Position adjustment system for a projection lens

A lens position adjustment system (10) permits adjustment of the position of a projection lens (5) relative to a projector (100) for making a Scheimpflug adjustment. The projection lens (5) has an optical axis (6). The system (10) comprises: a first support part (20) for fitting to, or forming part of the projector (100); a second support part (40) for fitting to, or forming part of the projection lens (5); and a connecting part (30). The connecting part (30) is pivotally connected to the first support part (20) and pivotally connected to the second support part (40) and configured to permit independent adjustment of the second support part (40) relative to the first support part (20) about two axes of rotation (7, 8) which intersect, and are perpendicular to, the optical axis (6) of the projection lens (5). A locking mechanism (28, 29, 51-58) is provided for securing a position of the second support part (40) relative to the first support part (20).

Start up cascaded fuel cell stack

A cascaded fuel cell stack (9a) includes a plurality of groups (10-12) of fuel cells (13) connected electrically in series by means of conductive separator plates (58, 59) and current collecting pressure plates (56, 57). Each group has an inlet fuel distributing fuel inlet manifold (17a, 19c, 20c), a fuel exit manifold (19a, 20a) of each group except the last feeding the inlet manifold of each subsequent group. A microcontroller responds to signals from a plurality of voltage sensing devices (48a-48c) to cause corresponding switches (50a-50c) (a) to connect each group, and all preceding groups in the sequence, to a voltage limiting device (VLD) (45), or (b) to connect each group to its own (VLD (45a-45c), in response to sensing a predetermined average cell voltage across the corresponding group. When normal operation occurs, the microcontroller connects the main load and disconnects the voltage limiting device (53) (25).

Switching amplifier using flyback transformer

A switching amplifying method or a switching amplifier for obtaining one or more than one linearly amplified replicas of an input signal, is highly efficient, and does not have the disadvantage of “dead time” problem related to the class D amplifiers. Another aspect of the present invention provides a switching amplifier that is completely off when there is no input signal. Yet another aspect of the present invention provides a switching amplifier for obtaining a plurality of different linearly amplified replicas of the input signal, and adds more slave outputs easily and economically.

Transport container for maintaining the temperature of frozen goods

The invention relates to a transport container (1) comprising a superinsulation in the form of an evacuated insulating container (2) comprising a vacuum maintaining material (55). The transport container is provided with a cooling container (16) comprising a heat-conducting metal wool filling (57) and an organic coolant which undergoes a solid / liquid phase change in the temperature range of between −30° C. and −850° C. and has a heat of fusion of at least 50 J / ml. A slim cylindrical sample chamber (24) is used to receive deep-frozen tissue samples (26), said chamber being surrounded by the cooling container (16) and merging into a long neck opening (25) forming a single component therewith, said opening being largely filled by the insulating shaft (30) of a screwable plug (28) and sealed from the sample chamber (24). The air in the ring gap (32) created can be evacuated by means of an evacuating system (48). The plug (28) is provided with a stopper (38) protruding into the sample chamber (24) and a data logger (41) for recording the temperature in the sample chamber (24). Following the freezing of the coolant, the transport container (1) enables distribution times and intermediate storage of up to 14 days without any risk of damage to the tissue samples (26) received therein.

Apparatus Support Structure

The invention relates to a pre-table system (V) for container handling machines, comprising at least in-feed and out-feed starwheels (A, Z), arranged such as to be driven on support housings (1), defining a starwheel configuration (K) in the pre-table system (V), within which the support housing (1) is fixed to a floor-standing support structure (S) whereby the support structure (S) has a tube and / or profile section frame (6) of sections (7) directly or indirectly detachably connected to each other at points (N) by means of the support housing and floor support feet (8), within which the support housings are arranged in a free-standing manner such that free areas (15) are formed around the support housings and at least some sections (7) may be combined together and with support housings such that the starwheel configurations (K) may be optionally altered.

Polyurethane foam handle and method for making the same

A polyurethane foam handle includes: a polyurethane foam having the shape and size of the handle; a coating layer formed on the surface of the polyurethane foam; and an additive disposed inside the coating layer, in which the additive is cork powder, white clay, yellow soil, a coloring matter, shellfish powder, metal powder, shiny powder, or a compound of them. The foam handle solves the problems due to using EVA or cork to make a handle and to achieve a polyurethane foam handle over the defects of polyurethane foam.

Two component powder coating system and method for coating a heat sensitive substrate therewith

[Wood] A heat sensitive substrate is [electrostatically] coated with a thermosetting powder coating system in which a mixture of a self-curing epoxy resin and a catalyst therefore is extruded and pulverized and a low temperature curing agent [are both] a pulverized and the powders are blended with conventional additives to make a coating powder which is deposited on [a wooden] the substrate and heated to cure. The mixture of resin and catalyst does not cure within the extruder but it is made to cure at low temperatures by the separate addition of the curing agent. A small amount of the low temperature curing agent, insufficient to cause substantial curing during extrusion may be used in place of the catalyst.

Repetition Action Mechanism for an Upright Piano

InactiveUS20090114074A1Additional deviceSimple and reliable configuration and constructionStringed musical instrumentsDriven elementEngineering
An improved device for providing the so-called magic touch effect during a double repetition, in an upright piano, is characterized in that said device comprises a plurality of keys said keys being swingably mounted on a keyboard frame and supporting, each, a suitably inclined slanted drive element, which can be screw adjusted and is intercoupled to a slanted swinging arm, operating as control angular variation continuous escapement energy lever in turn pivoted to an abruptely clockwise downstream slanted main bridge operatively swinging with the escapement lever which is coupled to a butt roller of a hammer, pivoted to a first pillar element, in turn supporting a plurality of adjusting buttons for adjusting a first and second escapements. To said main bridge assembly being coupled a second pillar element, to which is pivoted the lever of the second escapement supporting the adjusting button for adjusting its operating angle, cooperating with the lever of the first escapement, which in turn supports and adjusting button.
