Title: Safety device for trigger mechanisms, in particular for firearms
Inventor: SCARAMUCCI SERGIO
IPC: F41A17/74
Filed: 1992-05-07
Abstract: ABSTRACT In a trigger mechanism for firearms, in particular of the adjustable type for target-shooting pistols, the actuator of the mechanism is constituted by an elastic element (29) which is pivoted to the hammer (23) in an upward position and is pivoted, in a downward position, to an element (39) which can slide on the body (5) of the firearm; by acting on the sliding element, the elastic element is inclined so as to vary the direction of the actuation force with respect to the lever arm formed by the fulcrum (25) of the hammer with the upper pivot (27) of the elastic element. The safety device disengages the trigger from the operation of the firing mechanism.                           (Ref. Fig. 1)

Title: Emergency signaling device
Inventor: HOYLE PATRICK D
IPC: G08B5/38
Filed: 1992-08-11
Abstract: ABSTRACT      A switching device for flashing an installed light fixture, as for helping emergency response personnel locate a dwelling.  A switch housing which is mountable within a conventional junction box encloses a switch having "off", "on", and "flash" positions.  In the "flash" position, the switch cyclically completes and interrupts the installed 120 volt AC circuit so that the light fixture flashes on and off.  A triac is employed as a relay for completing the circuit, and a timer-controlled driver portion is provided for actuating the triac.  The triac driver actuates the triac at the beginning of each half-cycle of the AC current, in response to a low-voltage pulse which passes through a capacitor connected to the high-voltage lead.  The timer may be a 555 IC timer, and a conversion network may be provided for supplying DC current for this.  A piezoelectric element is also provided for generating an audible signal indicating that the "flash" mode has been actuated. The duty cycle of the device can be adjusted as desired, to provide anything from long-term illumination of the bulb to a short flash.

Title: Apparatus for detecting and signaling the function and status for an elevator safety brake
Inventor: LAMB MILES P
IPC: F16D59/02
Filed: 1992-09-30
Abstract: ABSTRACT OF THE DISCLOSURE    An apparatus for detecting and signaling the function and the status of an electronically actuated two-circuit safety disk brake for elevators includes an axially moveable spring centering bolt and a sliding block attached to each of a pair of brake shoes for actuating position sensors.  A force imbalance due to breakage of a brake pressure spring displaces the spring centering bolt from its neutral position and actuates a microswitch of a first position sensor by way of sliding block attached to the bolt to generate a signal to a monitoring circuit.  A double switching arm formed on the sliding blocks attached to the brake shoes signals not only the normal closure and opening movements of the brake, but causes, on exceeding an admissible wear of the brake lining for the first time, an alarm switching cycle of a microswitch of a second position sensor.

Inventor: TARUSAWA YOSHIAKI
IPC: G01R25/08
Filed: 1993-01-18
Abstract: A modulus counter counts first clock pulses to modulus M and outputs the count value as an m-bit reference signal, M being an integer.  A latch circuit samples and holds the reference signal in response to a trigger signal generated by a trigger signal generator in synchronism with an input signal.  A high-speed counter is supplied with second clock pulses of a frequency higher than that of the first clock pulses and starts counting the second clock pulses in response to the trigger signal and stops the counting in response to a first one of the first clock pulses immediately thereafter.  A data processor converts the n-bit count value of the high-speed counter to n-bit data corresponding to a phase fraction of a phase quantization step in the latch, combines the n-bit data as low-order bits with m-bit data from the latch and outputs the combined data as phase difference data.

IPC: G03D5/04
Filed: 1991-11-22
Abstract: It is known to provide agitation of processing solutions in photographic processing apparatus using jets. Jets are also known for urging material between sets of rollers. However, such jets are not known to impart drive to material being processed as it passes through the apparatus. Described herein is an arrangement in which material (M) is transported through a narrow elongate tank (20) by means of processing solution which is directed into the tank (20) by means of high speed jets (24, 25). The jets (24, 25) have two functions, namely to drive the material (M) through the tank (20) and to supply processing solution to the tank (20) simultaneously. Such an arrangement has the advantage of providing high speed processing apparatus which occupies minimum space and has few moving parts.

Title: Method and arrangement for the compression of gas
Inventor: GRATZ GUENTHER
IPC: F01K3/00
Filed: 1993-07-09
Abstract: A method and an arrangement for compressing gas in a compressor station for a gas pipeline, especially in areas of permanent frost, wherein the gas is supplied in the gas pipeline to the compressor station at an entry pressure and the gas is returned to the pipeline for further transportation in the pipeline at a desired exit temperature and at an exit pressure which is higher than the entry pressure. The gas is initially compressed at least during individual time intervals to an excess pressure which is substantially higher than the desired exit pressure. The compressed gas is then cooled by heat exchange to a temperature above the desired exit temperature. Finally, the gas is further cooled to the desired exit temperature by expanding the gas from the excess pressure to the exit pressure.

Title: Thermal sorting
Inventor: ROSS VICTOR E
IPC: B07B13/00
Filed: 1993-11-08
Abstract: The invention is directed to the sorting of particles according to the thermal properties of the particles. The method comprises, as a first step, subjecting the particles to one ox more thermal treatment steps so that particles with different intrinsic thermal properties are brought to different temperatures. In the next step, conducted either during or after the thermal treatment steps, the particles are subjected to a further, non-thermal treatment. This treatment is chosen to give selected particles that are distinguished from other particles by a difference in temperature a certain feature which is not an intrinsic feature of the particles prior to the thermal treatment step. The particles can then be sorted into a fraction having the certain feature after a predetermined time period has elapsed since the further treatment step and a fraction not having the certain feature after that time lapse.
