Title: An automatically and manually operable portable fire extinguisher
Inventor: MOHLER JOHANN GEORG
IPC: A62C35/02
Filed: 1985-04-01
Abstract: The nozzle-connecting and sprinkler-connecting body (1) contains a central longitudinal bore (3), a sprinkler (5) projecting at right angles to the longitudinal axis of the said bore (3) being arranged on its portion (3') on the inflow side. Adjoining the longitudinal bore (3) is a valve ante-chamber (20) which can be closed off on the outflow side by a valve device (14) and which leads into a flow deflection space (24) via a combination of a valve seat (17) and valve plate (16). A jet nozzle (31) located on the bottom of a jet pipe (30) is connected to this flow deflection space via a jet bore (27) opening out laterally. The nozzle-connecting and sprinkler-connecting body (1) is designed so that the fire extinguisher equipped with it can both be brought to the source of the fire by means of direct manual actuation (12, 13) and also serve as a stationary appliance in which the sprinkler (5) can be released by remote control as a result of the effect of heat or by means of alarms. <IMAGE>

Patent GB-2163213-A (GB)
Title: Ignition systems for internal combustion engines
Inventor: FRITZ ADOLF
IPC: F02P3/055
Filed: 1985-06-27
Abstract: The primary winding (5) of the ignition coil (6) has a shunt circuit including a thyristor (21), and the primary winding (5) is, before each ignition point, supplied during transitory periods of time with current from a DC source (1) through an output transistor (7). At the end of each such time period, the current induced in the primary winding (5) can flow through the thyristor (21). Thus, while storing the ignition energy, the thyristor (21) is forward biased during the off state of the output transistor (7) and reverse biased during the on state of the output transistor (7). A measuring resistor (8) is in series with the primary winding (5) and the output transistor (7) and is used to switch the output transistor (7) on and off while the ignition energy is stored. At the ignition instant, a control unit 14 switches on a transistor (20) thereby grounding the gate of the thyristor (21) and preventing it from switching on so that when the transistor 7 is switched off, a spark is generated. <IMAGE>

Title: Method of driving a liquid crystal apparatus
Inventor: OHTA MORIO
IPC: G06K15/12
Filed: 1985-09-09
Abstract: The present invention relates to a method of driving a liquid crystal light shutter for using a liquid crystal material whose dielectric anisotrophy becomes zero when a specified frequency is inputted is sealed between the common and signal electrodes (13, 14). The signal for driving the liquid crystal light shutters (15-18) comprises a signal the frequency of which is lower than the specified frequency and a signal obtained by superposing a signal of a frequency higher than the specified frequency on a signal of a frequency lower than the specified frequency. The signal for reversely driving the liquid crystal light shutters comprises a signal of a frequency higher than the specified frequency and a silence signal. A frequency fL3 lower than FL may be applied for a short period to further enhance on tendency. A high frequency hysteresis is avoided by the silent signal in the case of off- drive signal. Temperature characteristics are also improved. <IMAGE>

Title: An exercise machine
Inventor: KON ISRAEL
IPC: A61B5/22
Filed: 1986-02-21
Abstract: An exercise machine for human beings includes a member to be operated by a user (U) and load means (M) supplying a variable resistive force to resist operation of the member. A detector (A) monitors a physiological parameter, preferably pulse rate, of the user (U), which parameter alters in accordance with the degree of physical power applied to the operating member by the user. Control means (D) controls the load means (M) automatically in accordance with output from the detector (A) to thereby regulate the resistive force applied to the operating member. Preferably, the resistive force is varied in a time dependent manner subject. The user is monitored constantly and the level of exercise varied accordingly so as to ensure safety and optimum level of exercise. If the output from the detector does not remain within a range determined by the control means the exercise is terminated. <IMAGE>

Title: Pipe support
Inventor: SALTER ANTHONY JOHN
IPC: F16L3/21

Abstract: A constant tension pipe support has load attachment means and spring means connected in counterbalance to a pivoted lever 1 by connections of which at least one is adjustable such that the position of the connection can be moved transversely of the lever to vary the moment of the force applied to the lever at that connection. The moment adjustment may be made to compensate for a variation in the load exerted on the lever 1 by a supported pipe, or by the spring means, and may be made whilst the pipe support is in use. The preferred embodiment has the adjustable connection provided by a pin 22 associated with the load attachment or spring means engaged in registering portions of mutually inclined slots 13, 17 at the lever and in an adjuster 14 movable along the lever by a screw 19 to vary the position transversely of the lever at which the slot portions register. <IMAGE>

Abstract: To monitor machinery and plant in mining, i.e. in particular the hydraulic support system, a manometer is used comprising a Bourdon spring 7 and a Hall generator 9 via which the movement of the Bourdon spring is converted to electrical signals and then converted for remote display and by suitable accessories also for direct display. The Bourdon spring is made with high strength and thus is suitable for overloads occurring under-ground. The magnet 8 is fixedly connected to the spring and the Hall generator to the housing, which consists of two parts. The Bourdon spring, the magnet and the Hall generator are associated with one part and the sealed-in electronics with the other. The Hall generator, secured to the housing, is aligned with the magnet and is arranged in a bridge circuit with temperature compensation, running at a constant current of about 2.5 milliamps. The housing is filled with oil for damping externally- induced vibrations in the Bourdon tube. <IMAGE>
