Abstract: A security system including a security module positioned so that personnel traveling from a first zone to a second zone pass through the module for identification and verification of access. The module includes a card reader on one wall for reading an identification card inserted by the personnel, a scale for weighing personnel within the module, sensors for measuring the height, girth, position and direction of movement of personnel passing through the module, and video cameras for viewing such personnel. Information relating to whether the card is used properly, whether the card is correct and valid, whether issued to the person carrying the card and whether the person should be traveling between the zones at that time is determined and alerts provided when violations occur. The scale includes a floor plate suspended within the module.

Abstract: An elongate, rigid restraint member is disposed to be positioned by an arresting officer vertically behind a suspect's back. One ankle of the suspect is then releasably secured by a clamping mechanism to the lower end of the member, and a strap at the upper end of the member is secured snugly by the officer around the suspect's neck, thereby forming a substantially rigid restraint between the suspect's ankle and neck.

Abstract: A protective guard is provided for a lock cylinder in a door, which consists of a generally rectangular metal plate assembly having a central passageway therethrough. Components are for attaching the plate assembly to the door with the central passageway generally aligned with the lock cylinder. The attaching components are concealed, removable and adjustably connected to an inner side of the plate assembly, thereby rendering the lock cylinder less susceptible to tampering.

Abstract: A motorcycle lock is provided which includes a lock body consisting of a metal casing and a lock unit fitted into the metal casing. The lock unit includes two locking plates at the top and a lock cylinder at the bottom, and a shackle having two annular grooves around two opposite ends thereof and respectively inserted into a respective hole on the metal casing and locked by the locking plates. Turning the lock cylinder in one direction causes the locking plates to move in the reverse directions for permitting the shackle to be removed from the lock body. Turning the lock cylinder in the reverse direction causes the stop blocks of the left and right locking plates to engage the annular groove on opposing ends of the shackle for holding down the shackle.

Abstract: A dental chair has an armrest pivoted to a base at an armrest pivot, and a seat back pivoted to the base at a back pivot located forward of the armrest pivot. The seat back includes a support pin for supporting the armrest at a position forward of the seat back pivot. Moving the seat back from an upright position to a reclined position through a large range of angular motion causes the support pin to elevate the armrest by a substantially smaller angular amount.

Abstract: A mobile folding stage unit has right and left platform sections pivotably mounted in side-by-side relation to a frame, corresponding sets of roller wheels mounted to the frame, pivot brackets mounted to the bottom of the platform sections, support brackets mounted to the frame to which the platform sections are pivotably mounted via the pivot brackets, and pivot legs pivotably mounted to an eccentric position on the corresponding pivot brackets and slidable in pivotable bearing guides mounted to the frame adjacent the corresponding roller wheels. When the platform sections are folded to the vertical position for storage, the pivot legs are lifted above the wheels, and when they are opened to the horizontal position for use, the pivot legs are lowered to lift the wheels out of contact with the ground.

Abstract: This device is for preventing unauthorized access, and theft of automobiles license plates. This license plate lock works by first fastening the license plate locking device to the automobile with bolts that are put in back of the device. Next unlocking the lock in front of the device, this can be with a key lock, or combination lock. Next the movable arm swings up and down so that the license plate can be put inside of the device and locked up.

Abstract: In a chair having a seat which is adjustable in both height and tilt, there is provided a simplified adjustment mechanism over prior art document 2226756-A, in which a first adjustment mechanism is provided to tilt the seat of the chair to suit the physique of a particular user, which mechanism is compatible, and used in conjunction with a second adjustment mechanism which is used to vary both height and tilt of the seat cooperatively to suit the specific requirements of said particular user for being in a seated, or semi-standing position at various heights.

Abstract: A safety latching device for refrigerators of the type having at least one vertically-hinged door extending the entire length of the refrigerator. The safety latching device includes an elongated support base having a latching bar rotatably attached thereto secured to the top of the refrigerator, and a coupling plate having a slot therein secured to the top of the refrigerator door in alignment with the latching bar. To prevent the refrigerator door from being opened by a young child, the latching bar is positioned in the coupling plate slot. To allow access to the refrigerator by an adult, the latching bar is rotatably moved from the slot. For refrigerators having more than one vertically-hinged door, the safety latching device utilizes a pair of latching bars with a pair of corresponding coupling plates.

Abstract: To prevent the unauthorized unlocking of van doors equipped with safety rod locks, the lever of the safety rod lock is held to the door by a retainer clip. The retainer clip has an extending tongue with apertures in it that passes through the door into the van. In the van, there is a dead bolt which may be actuated by a key cylinder inserted from outside the van through the door to cause the dead bolt to enter an aperture and lock the extending tongue of the retainer and hold the retainer in place so that the lever cannot be moved to unlock the safety rod lock. A second key actuated member or solenoid actuated member is actuated to move a cam in front of the first key slot so that it cannot be unlocked until the second cam lever is moved out of the way. Thus, a sequence must be followed using two different actuating means to unlock the door or lock the door.

Abstract: A wheel clamp assembly to be applied on a road wheel of a vehicle to prevent unauthorized operation of the vehicle. The assembly includes a first elongate arm member and a catch member at one end of the first arm member projecting transversely of the first arm member. The first arm member and a second elongate arm member are each joined at their bottom ends to an elongate body member. The body member supports the arm members in spaced apart relationship so that the width of the road wheel can be accommodated between the arm members. The second arm member is movable relative to the first arm member between an inoperative position spaced from the first arm member an amount sufficient to permit the catch member to be located into and out of the wheel well opening, and an operative position wherein the second arm member is substantially parallel to the first arm member and extends transversely of the front face of the wheel. A key-operated locking mechanism retains the second arm member in the operative position.
