Title: Pressure transmitting device and diaphragm assembly therefor
IPC: G01L7/08
Filed: 1980-07-10
Abstract: A pressure transmitting device comprises a disc-shaped head 1, a hollow stem 3 and a diaphragm 25 closing one end of a central chamber in which a bleed nozzle 10 is mounted so as to be closable by the diaphragm or a closure member carried by the diaphragm.

Title: Photochromic glasses
IPC: C03C4/06
Filed: 1980-09-30
Abstract: A fast reacting photochromic alumino- phosphate glass having silver halide crystals dispersed throughout the glass, and a green colouration induced by the presence of a chromium oxide in the finished glass, wherein the finished glass also includes an oxide of antimony and/or an oxide of arsenic, and wherein the fading rate of the glass upon its removal from actinic radiation is such that in the course of fading from its fully darkened condition to its fully faded condition at least 25% of the total possible change in optical density of the glass occurs within 16 seconds. By including an arsenic oxide and/or an antimony oxide in a fast reacting alumino-phosphate photochromic glass composition in addition to a chromium oxide, one can overcome the deterioration in photochromic properties which is observed when a chromium oxide alone without antimony and/or arsenic oxide is added to such a glass composition.

Title: Piezoelectric resonators
IPC: H03H9/17
Filed: 1981-01-14
Abstract: In a thickness shear mode piezoelectric resonator comprising a plate 1 of piezoelectric material with an electrode 2 on a corresponding region of each main face, at ieast one region of the plate immediately adjacent the portion sandwiched between the electrodes is provided with additional mass loading 3 such that across the width of the electrodes the integral of the particle motion corresponding to a trapped anharmonic overtone is zero and no net piezoelectric charge due to said overtone is collected by the electrodes in operation.

Title: D.C. Limit Value Indicator
IPC: G01R19/165
Filed: 1981-03-04
Abstract: In a D.C. limit value indicator using a bistable magnetic element the direct current (Ix) to be monitored is compared with a reference direct current (Is), the two direct currents being passed through two galvanically separated windings (4, 3) whereupon the magnetic fluxes produced therein are compared. The two windings (4, 3) possess, as a common ferromagnetic core, a bistable magnetic element (1), in which, on reaching the predetermined direct current limit value, the direction of magnetisation is abruptly changed. As a result of the abrupt change of magnetic field thus produced, an electrical voltage pulse is induced in a further winding (5), which indicates that the limit value has been reached. By superimposing a pulsating magnetic field (HI) upon the resulting magnetic field produced by the reference direct current and the direct current to be monitored, on exceeding (or falling short of) the predetermined limit value, not only a single pulse, but a train of pulses, is induced. <IMAGE>

Title: Washing machine
IPC: D06F37/20
Filed: 1981-07-16
Abstract: A washing machine comprises a washing unit, which is capable of oscillating freely in a housing 1 and which comprises a container 3 supported by spring legs 2. Disposed on the container 3 is an abutment 4 which co-operates with a feeler 5 detecting the oscillatory travel of the container. Associated with the feeler 5, e.g. a bellows, is a switch 7, e.g. a pressure switch, which is mounted on the housing 1 and which above a certain oscillatory deflection of the container delivers a signal. The container 3 contains a rotatable drum driven by a drive motor, the rotational speed of which is controlled by a thyristor or a triac. To avoid damage of the machine, in the event of failure of the thyristor or triac, the switch 7 is arranged in the motor supply current circuit and is so actuated by the feeler 5 in response to sensing of an impermissible amount of container oscillation as to interrupt the motor current circuit. The switch 7 is not automatically resettable into its closed position, but can be re-set by a mechanical pull element 8. In another embodiment, Fig. 4 (not shown), the feeler is provided by a rocker (11) of a toggle switch (10) and is actuable by a resilient member (9) on the container (3). <IMAGE>
