Abstract: ABSTRACT OF DISCLOSURE A stud  driver has  threaded  jaws with thread relief provided on a leading edge area of the jaws to reduce thread marking or deformation of the thread on the stud when the stud is driven under high torque condi-tions.  The thread relief in the leading edge area of the jaws  creates  a  shallower  angle and  increases  contact area.   If the stud driver is subjected to unusually high torques, the increased contact area prevents shearing of the thread on the stud.

Granted: 1992-04-28
Abstract: ABSTRACT OF THE DISCLOSURE         The disclosure herein describes a vehicle for curbside  collection  of  source  separated  recyclable materials.   A dumping unit includes a box-like frame having  a  series  of  compartments  to  receive  the separated materials and includes, along one side wall thereof, a vertically movable trough having a series of compartments receiving the recyclable materials.   The trough moves upwardly along the said side wall to an upper  discharging  position  whereby  the  separated materials  are  dumped  into  the  compartments  of  the frame.    A  cylinder  located  centrally  between  the understructure   and   the   frame   cooperates   with pin-engaged hinge points on either side or rear of the frame to tilt the frame on any one side depending on where the pins are engaged in the hinge points.  Doors at the bottom of each compartment allow the discharging of the contents of the compartments whenever the frame is tilted on one side or the other.

Title: Dual hydraulic hospital bed with emergency bypass circuit
Inventor: BAILEY DAVID W
IPC: A61G7/018
Filed: 1988-06-13
Granted: 1991-01-29
Abstract: Abstract of the Disclosure A hydraulically operated hospital bed with dual hydraulic power systems for operation with or without electrical service.  The bed has  its  head and thigh/leg  elevation  functions  performed by hydraulic cylinders.  A control circuit meters the introduction and removal of hydraulic fluid from these cylinders so an occupant of the bed is not subjected to any sudden movement.  In case of an emergency requiring the bed occupant to be in a supine position (the need to perform CPR), the normal control circuit is bypassed by an emergency circuit that allows much faster than normal lowering of the head and thigh/leg portions of the bed.

Title: Shock absorber
Inventor: NISHIMOTO YUKIO
IPC: F16F9/49
Filed: 1988-07-26
Granted: 1992-08-04
Abstract: ABSTRACT OF THE DISCLOSURE   A shock absorber adapted to be mounted between a body and a wheel shaft in a vehicle such as a car or a motorcycle for reducing shocks and vibrations derived from a road. The shock absorber includes a sub-cylinder mounted in a cylinder at one end thereof, a rebound cushion mounted in the sub-cylinder at one end thereof, and an oil-lock piston mounted on a piston rod of the cylinder in confronting relation to the interior of the sub-cylinder. As the piston approaches the end of the expanding stroke, the oil-lock piston is fitted in the sub cylinder, at which time oil in the sub-cylinder is compressed and then flows into an oil chamber below the oil-lock piston via an annular gap around a periphery of the oil-lock piston and a small-diameter hole in the oil-lock piston. Due to the flow resistance of the small-diameter hole, an oil-lock load can be obtained. As the piston arrives at the end of the expanding stroke, the oil-lock piston abuts against the rebound cushion so as to keep a bearing at a head of the cylinder from violent impacts.

Abstract: An electric activating system for vehicle roofs and openable members in which an openable member is opened and closed by rotation of driving shafts provided on right and left sides.  The system includes a motor which rotates the driving  shafts  via  a  reduction mechanism  and  switching relays  which  switch  the  rotational  direction  of  the motor.   Open  and  close  command  switches  command  the opening and closing of the openable member and a rotation synchronization sensor associated with the motor generates pulses  synchronized with the  rotation of  the motor.  A mechanical  stopper  limits  the  rotation  of  the  driving shaft which is rotated via the reduction mechanism of the motor and a motor lock detecting means detects locking of the motor by detecting the pulse width generated by the rotation  synchronization  sensor.   Also,   an  actuation stopping arrangement stops the actuation of an actuation device which supplies current to the motor if a signal is generated by the detection apparatus that detects locking of the motor.

The adjustment device includes a rod mounted at or in the basic element which is longitudinally displaceable and articulated to the pivot arms to positively control them and which, if displaced longitudinally, pivots the pivot arms.  It is advantageous for the end of the rod facing the pivot arms to be connected with the pivot arms by guide arms. It is further desirable that the basic element be configured as a tube and the rod be displaceably mounted in this tube. the end of the rod remote from the pivot arms projects out of the tubular basic element and is provided with a thread onto which a nut is threaded when the rod is pushed axially into the tube, it forms a stop which lies at the end of the tube. The pivot arms are bent at right angles in the elevational direction and the individual components of the instrument are composed of a high strength light metal, preferably of titanium.

Abstract: A novel retinoic acid receptor is disclosed. The novel receptor is encoded for by cDNA carried on plasmid phRAR1, which has been deposited with the American Type Culture Collection for patent purposes. Chimeric receptor proteins are also disclosed. The chimera are constructed by exchanging functional domains between the glucocorticoid, the mineralocorticoid, the estrogen-related, the thyroid and the retinoic acid receptors. In addition, a novel method for identifying functional ligands for receptor proteins is disclosed. The method, which takes advantage of the modular structure of the hormone receptors and the idea that the functional domains may be interchangeable, replaces the DNA-binding domain of a putative novel receptor with the DNA-binding domain of a known receptor such as the glucocorticoid receptor. The resulting chimeric construction, when expressed in cells, produces a hybrid receptor whose activation of a ligand-(e.g., glucocorticoid) inducible promoter is dependent on the presence of the new ligand. The novel method is illustrated in part by showing that the ligand for the new receptor protein is the retinoid, retinoic acid.

Abstract: METHOD AND APPARATUS FOR RESOLVING A VARIABLE NUMBER OF POTENTIAL MEMORY ACCESS CONFLICTS IN A PIPELINED COMPUTER SYSTEM                    ABSTRACT      An operand processing unit delivers a specified address and at least one read/write signal in response to an instruction being a source or destination operand, and delivers the source operand to an execution unit in response to completion of the preprocessing.  The execution unit receives the source operand, executes it and delivers the resultant data to memory.  A "write queue" receives the write addresses of the destination operands from the operand processing unit, stores the write addresses, and delivers the stored preselected addresses to memory in response to receiving the resultant data corresponding to the preselected address. The addresses of the source operand is compared to the write addresses stored in the write queue, and the operand processing unit is stalled whenever at least one of the write addresses in the write queue is equivalent to the read address.  Therefore, fetching of the operand is delayed until the corresponding resultant data has been delivered by the execution unit.
