Abstract: A breech lock wireline connector for connecting tools to a wireline inserted into a well bore. The connector has a housing with an axially movable plunger within the housing and each being in axial alignment. A spring is used for biasing the plunger axially toward and into engagement with the breech pin. The breech pin is selectively engageable and disengageable into lock and unlock positions, respectively, with the plunger and the housing. The plunger rotates the breech pin axially between the lock and unlock positions. A latch is provided for latching the plunger and breech pin in the lock position.

Abstract: Door stop apparatus includes a block secured to a vehicle and a bar extending through a generally horizontal bore in the block. The bar is secured to a vehicle door and includes stop recesses spaced apart from each other. The bar extends through a cylinder a generally vertical bore in the block and the cylinder includes a biased roller which extends sequentially into the stop recesses on the bar to provide intermediate stops for the vehicle door. The cylinder pivots or rotates in the bore as the door moves.

Abstract: In some embodiments of the present invention, a freewheeling lock assembly is provided that includes a housing at least partially defining a cavity and having a central axis, an actuator rotatably coupled to the housing and substantially axially fixed with respect to the housing, a lock cylinder received within the cavity, having a locked configuration and an unlocked configuration, and rotatable with respect to the housing in both the locked and unlocked configurations, and a clutch having a sleeve and a disk that are received by the cavity and that selectively couple the lock cylinder and the actuator for rotation together in response to rotation of the lock cylinder in one of the locked and unlocked configurations. In some embodiments, the lock cylinder remains substantially axially stationary with respect to the housing when rotated.

Abstract: A grommet includes a first cylindrical portion 21 for passing a wire harness therethrough, a second cylindrical portion 22 for fitting in a mounting hole 12 in a panel 11, and a connecting portion 23 interconnecting the first and second cylindrical portions 21 and 22. The second cylindrical portion 22 is turned inside out, and flange portions 25, formed on the second cylindrical portion 22, are passed through the mounting hole 12. Subsequently, the second cylindrical portion 22 is restored into its initial shape by its own restoring force, thereby mounting the grommet in a predetermined position. Ribs 30 are formed on an inner peripheral surface of the connecting portion 30, and the position of folding of the connecting portion 23 is determined by these ribs, thereby preventing the grommet from being excessively reversed, and by doing so, the restoration of the grommet into its initial shape can be easily started.

Abstract: A hydrodynamic shaft seal formed with a spiral hydrodynamic channel in which successive turns of the channel are of progressively diminishing volume toward an air side of the seal. The channel is made by forming a spirally extending first cut in a surface of the seal, and forming a spirally extending second cut in the surface of the seal adjacent to the first cut such that the first and second cuts intersect below the surface of the seal to produce a spiral channel. The spiral of the first cut has a lead different from the lead of the second cut such that the channel is of progressively diminishing volume along its length. Alternatively, the second cut may have the same lead as the first cut for the first few turns, after which the lead of the second cut may be reduced, to provide a channel of constant volume for the first few turns, followed by a channel portion of reduced volume.

Abstract: A remote-controlled door lock includes a housing installed inside with a battery base, a circuit board and an electromagnetic valve. The electromagnetic valve is fitted with a lateral valve rod controlled by the circuit board to extend out of the through hole in a sidewall of the housing and engage in the insert hole in a sidewall of the bolt base of a doorjamb. A remote controller is operated to control the valve rod of electromagnetic valve to move outward and extend out of the through hole of the housing and engage in the insert hole of the bolt base to lock the door at a limited position. Thus, the door lock is impossible to be unlocked only by a key before the valve rod of the electromagnetic valve is released by the remote controller to disengage from the insert hole of the bolt base, having best effect of anti-theft.

Abstract: A hinge device. The device includes an elongated main frame that extends along a first axis. The device includes an elongated pivot rod that extends along the first axis and that has a pivot end portion coupled pivotally to a stationary fixing block such that the pivot rod is rotatable axially about the first axis, and a connecting end portion connected to the main frame. A pivot unit includes an elongated pivot shaft that extends along a second axis transverse to the first axis. The pivot shaft has an upper end portion opposite to a lower end portion, which is coupled to the main frame, and projecting from the main frame. A pivot member is coupled pivotally to the upper end portion of the pivot shaft. A positioning unit is mounted on the main frame and is operable so as to prevent axial rotation of the pivot member about the second axis.

Abstract: The invention relates to a unique door hinge which does not employ pin receiving knuckles which are normally us in more conventional hinges. The unique hinge, provides two hinge leafs, the first of which has a flat web which terminates at an open end loop which is coextensive with the web and defines a space for matingly receiving a head portion which is at the termination of the web of the second leaf. The head portion is rotatable within the loop portion and is segmented by longitudinally spaced spaces for receiving plastic bearings which facilitate rotation of the hinge and support the movable hinge leaf relative to the fixed hinge leaf of a normally mounted door hinge.

The invention has a connection device for transmission of force from the lock cylinder to the carrier is provided to be axially displaced in relation to the lock cylinder from a neutral position and in direction towards this during rotation of the lock cylinder with a fitting key. The connection device is provided to be brought to an active position in friction engagement with the carrier not until after the axial displacement from the neutral position, after which locking and unlocking respectively of the lock device is performed by further rotation of the lock cylinder by means of the key.

Abstract: A sliding resistance member (3) is interposed between a glove box (B) and a rod type air damper (21). It is assumed that when a glove box lid (L) corresponding to a open-close member starts opening, the rod type air damper (21) rotates while running idle in conjunction therewith, in a relation in which the rotary type oil damper (3) is positively interposed between the glove box (B) corresponding to the mounting shaft and the rod type air damper (21). However, since a braking force of the sliding resistance member (3) is applied to the side of the open-close member in a rotating section of the rod type air damper (21), an sufficient damper effect can be obtained even when the open-close member starts opening.

The waterstop ring includes an annular waterstop member projecting from an outer circumference thereof, and a pair of annular shoulder portions respectively disposed on each side of the waterstop member. The waterstop member and each of the shoulder portions each include hollow annular cavities defined therein, such that when the waterstop ring is installed in a connection between a concrete structure and a pipe, and partially embedded within the concrete structure, the annular cavities allow deformation of the waterstop ring and thereby allow tilting movement of the pipe in a direction away from the central axis of the pipe.

Abstract: A wheel mechanism for controlling turning of the front wheel of a stroller includes a vertical axle and a latch mechanism. The upper end of the vertical axle is pivotally connected to the frame of the stroller. The lower end of the vertical axle is fixed to a horizontal axle of the wheel. The latch is movably mounted along the vertical axle and the frame and selectively moved between a released position and a locked position. When in the released position, the wheel can freely turn around the vertical axle. When in the locked position, the wheel cannot turn on the vertical axle but only rotates with the horizontal axle in a certain direction.
