A head and neck protection system includes a head protector, a shoulder protector, and a neck guard for protecting an athlete from injury. The neck guard detachably connects between the head protector and the shoulder protector and includes a collar. The collar has a first edge and a second edge spaced apart from the first edge and longer than the first edge. The first and second edges include fasteners for detachably coupling the collar between the head protector and the shoulder protector. The collar has a perimeter that flares radially outwardly as the collar extends from the head protector to the shoulder protector. The collar interconnects the head protector with the shoulder protector to form a restraint that limits displacement of the head protector relative to the shoulder protector.

An improved injection site (12) for infusion of parenteral fluids and the like is provided, having a pressure-actuated valve (20) and a novel split septum unit (24), which effectively prevent reflux of blood into the assembly (10). The septum unit (24) includes a resilient split septum body (64) which is precompressed so that the septum body (64) is caused to protrude proximally (78) upon insertion of a cannula (16). Consequently, upon removal of the cannula (16), there is essentially no “drumming” or creation of friction-induced negative pressures sufficient to generate blood reflux. The preloaded septum body (64) also has its proximal surface (74) essentially flush and coplanar with the adjacent proximal end (66b) of the tubular septum holder (66) to enhance the cleanliness of the unit (24). The specialized well (46) and septum unit (24) afford a resilient seal between the periphery of the septum body (64) and the surface (50), and a separate hard-surface seal between the outer margin of the surface (50) and the septum holder (66).

A grip portion is formed by a pair of half-split grip portions and grips an end portion of a tubular cable cover exteriorly mounted on a cable when the half-split grip portions are joined. A clamp portion is formed by a pair of half-split clamp portions and clamps the cable exposed from the end portion when the half-split clamp portions are joined. A clamp protrusion is formed on an inner surface of the clamp portion and clamps the cable exposed from the end portion by pressing the cable in a radial direction.

Inspection of circumferential sections of pipe or other conduit using an ultrasonic scanning apparatus is provided, wherein axial drift of the ultrasonic scanning apparatus is prevented using a guide track assembly. The guide track assembly is rigidly coupled to the ultrasonic scanning apparatus in the axial direction, but allows rotational motion of the ultrasonic scanning apparatus directly along the outer surface of the conduit using a drive chain that is driven by a circumferential drive. Secure rotational motion without drift between the guide track assembly and the ultrasonic scanning apparatus is maintained by the rigid coupling and by a spring-loaded wheel housing assembly that maintains contact of wheels that travel along the guide track. The ultrasonic scanning apparatus includes a transducer with spring-loaded gimbaling that maintains optimal proximity with the conduit surface. The transducer is translated axially along linear journals that extend along the conduit with a linear actuator.

The invention discloses a shield construction method for a two-line overpass with small radius, shallow covering soil and large longitudinal slope complex linear tunnel, which belongs to the technical field of tunnel construction. The construction method of the present invention includes the following steps: determining the advancing sequence of the two-line interchange, selecting a shield machine type, taking auxiliary strengthening measures for the ground surface, strata, and segments, shield advancing, axis control and construction monitoring, and shield tunneling. In the present invention, since the shield increases the hinged part, the sensitivity of the shield is increased, and the control of the axis of the tunnel is more convenient; a suitable reinforcement and pressure scheme, a segment typesetting method and a stiffening rib scheme are selected to make the outer arc of the segment broken. Cracks and segmental water seepage can be improved; and through high-frequency monitoring and information feedback, the shield propulsion parameters are strictly controlled. By taking the above measures, the deformation and displacement of the ground surface and the tunnel are effectively controlled, which effectively reduces the cost of tunnel construction and The complex influence of the post-construction tunnel ensures the smooth progress of the construction and the effective control of the tunnel deformation.

A handgun holster permits sideward extraction of the weapon, and engages with the central portions of the handgun without regard to accessories mounted to the front or beneath the barrel. The holster has a main element which engages the central region of the pistol in a snap fit between two opposed arms. Lateral projections extend from the back wall to restrict the side-to-side displacement of the gun and two resilient flaps extend around the engaged gun, providing additional retention, and covering the on / off switch of any flashlight accessory. The main element is connected to a mounting assembly to permit the main element to be set at any desired angular orientation with respect to the mounting assembly. The mounting assembly has two expandable parts with opposed flanges which permit mounting to either a conventional belt, or to a series of webbing pockets, such as in the military's PALS webbing attachment system.

The invention herein allows for manually positioning telescoping members relative to each other in a variety of positions within a given range of motion such as for movable chair backs or arms. A strut is engaged with and telescopically slides in a mounting member while deformable guide members provide for frictional engagement of the strut within the mounting member. A détente limits the range of motion of the strut relative to the mounting member. The détente comprises a stud or tab which engages a slot in the mounting member.
