A substance delivery device capable of insertion into a body cavity of an animal, with the delivery device including a body capable of housing a delivery apparatus capable of actively being controlled to autonomously deliver at least one substance into a body cavity of an animal, with the delivery apparatus including dedicated pressure systems to deliver the at least one substance from independent reservoirs via at least one associated outlet, with the at least one substance ranging in form from substantially fluid to substantially solid, with the device also including a programmable control device capable of initiating and regulating delivery of the at least one substance in accordance with a preferred delivery regime, and with the body further including a tail portion adapted to receive retention apparatus external to the animal and capable of effecting retention of the substance delivery device within the body cavity of an animal.

A method is disclosed for two-stage stretch forming of a sheet metal blank workpiece between a preform tool with a concave cavity and an opposing finish-form punch tool. Both tools are independently heated to different forming temperatures with the preform tool being hotter. Gas pressure is first applied to one side of the workpiece in the first forming stage to balloon it into the cavity of the preform tool. Gas pressure is then applied to the other side of the preformed workpiece to stretch it against the finish-form surface. The hotter preform tool enables faster forming and gas venting in the first stage. The cooler finish-form tool enables the final shaping of the part and its undistorted removal from the punch surface.

An electrical connector (100) includes an insulative housing (2) defining a plurality of passageways (21) and a plurality of contacts (1) received in corresponding passageways. Each contact includes a moveable part (10) forming a pair of guiding beams (105), an immoveable part (20) coupled with the moveable part and a biasing device (30) constantly urging the moveable part away from immoveable part. The immoveable part includes a pair of posts (205) and defines a pair of guiding slots (207). The guiding beams are received in the guiding slots and are capable of moving with regard to the immovable part along opposite surfaces of the immoveable part. The guiding beams and the posts are decussated to surround the biasing device for preventing the biasing device from disengaging therefrom.

A round circular hose has a tendency to kink when extended. Also, a round circular hose can be difficult to form into a coil. With this background I have developed a hose with rigid sides to prevent kinking and for ease for forming into a coil provided with thicker wall sections.

A cockpit assembly generally includes a cast alloy backbone, an intermediate plastic support member, and an instrument panel. The cast alloy backbone extends laterally and defines attachment features. The intermediate support member provides structural support to the various devices of the cockpit assembly, and is connected to the backbone through molding of the plastic around the attachment features. The instrument panel is connected to the support member and defines an interior surface exposed to the passenger compartment of the vehicle.

A slip sheet for use with unitized loads has a plurality of banding anchors. The banding anchors extend from an edge of the slip sheet or from a portion of the slip sheet tab. The banding anchors may be provided on one, two, three, or four edges of the slip sheet. The banding anchors may be folded up against the side of a unitized load to provide a place for packaging bands to engage the slip sheet. Portions of at least one slip tray sidewall are separated from the remaining sidewall to form flaps that may be folded down to function as tabs that help lift vehicles get under the slip tray.

A cloth-type vehicle laundering implement includes a support mechanism consisting of a rotatable drive shaft and a plurality of generally parallel, adjacently arranged spacers mounted on the support mechanism. Each of the plurality of spacers includes a first face and a second face. The implement includes a plurality of individual circular fabric disk elements disposed between the first face of one of the plurality of spacers and the second face of another of the plurality of spacers. Each of the plurality of individual circular fabric disk elements extends outwardly beyond the spacers. Each of the individual circular fabric disk elements consists of a single piece of non-woven material having an inner diameter and an outer diameter. The inner diameter is retained in a single plane by a securing mechanism such that more material is located adjacent the inner diameter than the outer diameter to provide a more rigid element. The outer diameter and the inner diameter consist of substantially the same linear length of material.

According to the present invention there is provided a MEMS device comprising, a mirror which is connected to a fixed portion by means of a first and second torsional arm, each of the first and second torsional arms are configured such that they can twist about torsional axes so as to oscillate the mirror about a first oscillation axes, and wherein the first and second torsional arms are each configured to have two or more meanders and wherein the first and second torsional arms are arranged symmetrically relative to the first oscillation axis.

Piezoelectric vibrating pieces are disclosed that include a base portion and first and second vibrating arms extending in a longitudinal direction from the base portion. Each vibrating arm has first and second main surfaces, a first groove on the first main surface, and a second groove on the second main surface. The grooves extend in the longitudinal. By adjusting the length and shapes of at least the first grooves relative to each other, the rigidity of the vibrating arms can be balanced and adverse effects of deformed regions between the vibrating arms caused by anomalous etching can be reduced.

A fireproof and thermal insulator product (1) including an Alkaline Earth Silicate (AES) material (2), and at least one of the following: a liquid barrier film (5), an FRP (Fiber Reinforcement Plastic) layer (4), cork (3), wherein the liquid barrier film (5) and the FRP layer (4) are staked onto the AES material (2), and wherein the cork (3) material is also staked onto the AES material (2) or embedded into said AES material (2) in where said cork (3) is configured as a plurality of strips performing a grid structure infilled with the AES material (2).

An object of the present invention is to provide a polypropylene polymer film superior in convenience in handling that does not generate troubles such as wrinkling, elongation or breakage during processing at a high temperature of 80° C. to 120° C., independently of the conveying method used in the drying step, and an adhesive film having the polypropylene polymer film as its carrier. Provided are a polypropylene polymer film, characterized by having a tensile modulus of 300 MPa to 1,000 MPa under an atmosphere at 23° C. and 60 MPa to 120 MPa under an atmosphere at 120° C. and an adhesive film containing it as the carrier.
