Title: Portable tubular magazine for shotgun or rifle
Inventor: IRIYE ALBERT
IPC: F41A9/18
Filed: 1990-05-15
Abstract: ABSTRACT            An apparatus for loading shotguns or rifles to capacity in  one operation by the use of a pre-loaded  portable tubular magazine  (2)  which can be locked  inside a rigid steel guide tube (6) connected to the firearm in place of it's conventional tubular magazine. The  portable   tubular magazine  (2)   comprises a rigid steel tube  capped at one end and tapered at the other to contain  a  magazine  spring  (15)  and  cartridge  pusher (16). Cartridges  (17)  are inserted over a spring loaded cartridge retainer (18) and are released  inside the guide tube  (6)  when the cartridge retainer lifter (9) is raised by ramps  (10)  at the end of a slot  (12)  which forms a channel  in the guide tube (6) for the cartridge retainer housing  (21).  The fore end  (7)  fitting over the guide tube   (6)   is similarly slotted and   is  connected  to conventional slide bars (8). At  the  front end of the guide tube  (6)  limiting the forward travel of the fore end  (7)  a two piece barrel clamp  (3) incorporates mounting brackets  (4)   for lock levers (5) having two laterally spaced teeth. When the lock ring  (14)  on the portable tubular magazine (2) engages the front tooth the cartridge retainer lifter (9)  is clear of the lifting ramps (10) and cartridges are not released until the ring  (14)  engages the back tooth in the fully seated position  . In this  position it  is possible to load cartridges  in the conventional manner.

Abstract: Methods and artificial matrices for the growth and implantation of cartilaginous structures and surfaces and bone are dis-closed. In the preferred embodiments, chondrocytes are grown on biodegradable, biocompatible fibrous polymeric matrices. Op-tionally, the cells are proliferated in vitro until an adequate cell volume and density has developed for the cells to survive and pro-liferate in vivo. One advantage of the matrices is that they can be cast or molded into a desired shape, on an individual basis, so that the final product closely resembles a patient's own ear or nose, Alternatively, flexible matrices can be used which can be ma-nipulated at the time of implantation, as in a joint followed by remodeling through cell growth and proliferation in vivo. The cul-tured cells can also be maintained on the matrix in a nutrient media for production of bioactive molecules such as angiogenesis inhibiting factor, Examples are provided showing the growth of hyaline cartilage for joint relinings, the growth of elastic cartia-lage for plastic or reconstructive replacement of cartilage structures, and repair of large bone defects.

Title: Transport refrigeration system having means for enhancing the capacity of a heating cycle
Inventor: HALEY JAMES H
IPC: F25D29/00
Filed: 1992-02-20
Abstract: 56,392 ABSTRACT OF THE DISCLOSURE           A transport  refrigeration system which includes a compressor, a condenser,  a receiver,  an evaporator, an accumulator,  and  a control  valve  having  cooling  and heating output ports which are alternatively  connected to first or  second refrigerant  circuits to initiate cooling and heating cycles, respectively.  The heating capacity of a commanded  heating cycle  is enhanced prior to switching to the heating  cycle  by  connecting  the  outlet  of the receiver to the second refrigerant circuit while maintain-ing the control valve cooling  port  active  in  the first refrigerant circuit  for a predetermined time delay.  This forces liquid  refrigerant in  the condenser  to flow into the receiver and then into the second refrigerant circuit, making  additional  liquid  refrigerant  available  to the heating  cycle,  which  is  initiated  at  the  end of the predetermined  time  delay,  without   introducing  liquid refrigerant directly into the accumulator.

Inventor: KELLER SILVANO
IPC: B05B7/14
Filed: 1992-03-31
Abstract: The apparatus comprises a volumetrically working metering unit (1) and a weighing device (12, 13) which together allow a gravimetric powder metering. The metering unit (1) has a rotating metering plate (3) of vertical axis of rotation, a driving part (4) arranged underneath the metering plate (3) and, above the metering plate, powder supply and extraction devices (9, 8). This metering unit (1) of predominantly vertical extent is fixed on a weighbridge (12) which rests on a plurality of weighing cells (13). The arrangement is such that the driving part (4) is located underneath the weighbridge (12), so that the centre of gravity of the entire metering unit (1) is at least approximately level with the weighbridge (12). The tendency of the metering unit (1) to oscillate can thereby be greatly reduced in comparison with a metering unit arranged completely above a weighbridge, with the result that a gravimetric powder metering of high accuracy and uniformity is achieved. <IMAGE>

Title: Stimulator for surface stimulation in paralyzed patients
Inventor: GRAUPE DANIEL
IPC: A61N1/36
Filed: 1990-11-26
Abstract: The system of the present invention is a stimulation system (100) for providing upper-motor-neuron paralyzed patients with capabilities of unbraced standing and unbraced walking, which consists of a single pulse power and amplifier (103) that outputs various trains of stimulation pulses and which is totally under microprocessor (104) generation and control, where the microprocessor's microcomputer selectively performs multiplexing of the pulse trains and their selective alternate distribution to the various surface electrodes attached to the skin of the patient at the appropriate stimulation locations. It also controls pulse-width, pulse-duration, pulse-amplitude and pulse-shape. Furthermore, the system can compute and activate (audible and/or visual) warning signals to warn the patient when the system is close to its maximal output.  This would happen when muscle fatigue is such that no further increase in stimuli level can keep the patient upright. The system computes and outputs indications of the various stimuli levels to a visual display, and it provides automatic fail-safe and override capabilities to help ensure that the patient does not fall in case of major circuit or system failure or misactivation. This is a critical capability since this system will be used by paraplegics who lack sensation in their lower extremities.

Abstract: ABSTRACT OF THE DISCLOSURE   The invention relates to a mechanism for advancing flat-laid package blanks (10) disposed in a magazine (14). A shaft (1) extending through the mechanism at right angles to the magazine (14) is journalled by means of a free-wheel hub (5) so that it may rotate in only one direction. The shaft (1) is urged against at least one endless elastic belt (9) which interconnects two or more wheels (11). In its turn, the belt (9) presses against the flat-laid package blanks (10).      The free-wheel hub (5) is surrounded by a lever (6), reciprocally pivotal and connected to a drive unit (8). When the lever (6) is pivoted in the one direction, the movement is transferred via the shaft (1) to the belt (9) and the package blanks (10) are fed forwardly in the magazine (14). When the lever (6) is pivoted in the other direction, the free-wheel hub (5) locks and no movement is transmitted to the belt (9) which might counteract the forward advancement of the package blanks (10) in the magazine (14).

Title: Method of determining the short-circuit impedance of an electrical power supply system to be monitored
Inventor: BOEHME KLAUS
IPC: G01R27/16
Filed: 1991-08-28
Abstract: In a process for finding the short-circuit impedance of an electric power supply system to be monitored, coefficients of a system matrix Xi or a system matrix Xu1 of a preselected model of an electric power supply system is calculated taking account of the mains frequency of the system to be monitored and the preselected time sequence of scanned values of a measurement value proportional to the current and voltage in the system. Starting with preselected parameter vectors .beta.i(O) or .beta.u1(O), error vectors at a predetermined smallest error vector are found with the actual scanned values of the measurements and the actual system matrix Xi or Xu1 by recursive estimation and the short-circuit impedance is determined therefrom. In order to avoid errors through the effect of an arc in finding the short-circuit impedance, in the process of the invention the system matrix Xu1 is calculated by including and taking account of the actual sign of the scanned value (yi(k)) of one measurement; in addition, an additional component taking account of a short circuit arc is included in calculating the parameter vector .beta.u1.
