Abstract: 1478900 Bidets M B BARRADA 8 July 1974 30195/74 Heading A4N [Also in Division E1] A water closet bowl is provided with a cleaning water supply passage 35, Fig. 1A, having an inlet for connection to a water supply pipe 21 and a single outlet (37), Fig. 1B (not shown), fixed to or integral with the bowl in the upper margins thereof and adapted to direct water as either a jet or a spray horizontally towards a user when seated, and a valve 22 to control the flow through the passage 35. The passage may be part of a hinge construction for the seat of a conventional water closet bowl (11), Fig. 1 (not shown). In other embodiments it may be formed integrally with the bowl, Figs. 2-5 (not shown). The bowl 50, Fig. 2A, of vitreous china has the cleaning water supply passage 61, with inlet 63 and outlet 65, cast into the flushing water inlet 52 of the bowl, the valve (not shown), being on or near the closet seat. Alternatively, the cleaning water supply passage may be separately formed from e.g. plastics, metal or glass, and be inserted into a bore formed in the bowl. Internal voids may be cast in a bowl by the use of plaster plugs or collapsible rubber tubes, which are removed after the form has hardened. The outlet of the cleaning water supply passage may be located either at the rear of the bowl and directed forwardly, Figs. 1-5 (not shown), or at the front of the bowl and directed rearwardly, Figs. 6 and 7 (not shown). Alternatively, a front outlet may be provided in addition to a rear outlet. The control valve may be replaced by a mixer tap unit, so that a mixture of hot and cold water may be supplied.

Title: Improvements in or relating to the control of hydraulic operating apparatus including hydraulic brakes
Inventor: ORLOFF GEORGE

Filed: 1949-11-24
Abstract: 669,527. Aircraft wheel brake. BRITISH MESSIER, Ltd. Oct. 27, 1950 [Nov. 24, 1949], No. 30202/49. Class 4. [Also in Groups XXXI and XXXIV] In a fluid pressure brake system for an aircraft, the normal operation of the brakes is by a rod 63 coupled to the brake pedal (not shown). Movement of rod 63 pivots a lever 61 about its pivot 62 thereby causing the arms 46 and 56 of two levers pivoted to the lever 61 at 60 to open or close pairs of contacts 47, 48 and .57, 58. These contacts form part of the circuits for solenoids 49. 79 and 59, 89 which control the operation of cocks 41 and 51 so as to connect the wheel cylinders 72, 82 either to a source of fluid pressure by pipe 70 or to exhaust through pipe 90. When a certain pressure has been attained in the cylinders 72, 82, this pressure reacting through pipes 73, 83 on the restoring jacks 74, 84, causes operation of the contact elements 47, 48 and 57, 58 in such a way as to shut off the fluid pressure supply to the cylinders 72, 82. So as to provide for differential actuation of the cylinders 72, 82 for steering purposes, a rod 92, connected to the rudder bar, when moved in one direction pivots about point 60 the lever arm 46, and in the other direction the arm 56, only those contacts affecting the control of the brake cylinder on one side being altered at a time.

Abstract: 1, 247, 611. Paramagnetic gas analyser. SIEMENS A. G. June 13, 1969 [June 13, 1968J, No.30242/69. Heading G1N. A paramagnetic gas analyser comprises a chamber MK, supplied by ducts Z1, Z2, and orifices E1, E2 with a comparison gas V, and by a duct MG with a gas to be tested MA, the two gases mixing in a region B in which the alternating magnetic field from yoke J is homogeneous, and discharging together through a duct A. The pressure difference existing, in use, across the chamber is measured by two heated resistive grids G1, G2, in the path of gas flow through a duct QV linking the supply ducts Z1, Z2. Flow regulating filters Stl, St2 produce laminar gas flows. In an alternative embodiment, Fig.2 (not shown) the position of the chamber is rotated through 90 degrees with respect to Fig. 1. A pressure-sensing switch may be disposed in the supply duct Z to actuate a solenoid valve to close the duct MG if the flow through Z falls below a predetermined value. The magnetic field may be pulsed. The resistive grids may be in a bridge circuit.

Title: Semiconductor transducer
IPC: H04R23/00
Filed: 1969-06-16
Abstract: 1277052 Gramophone pickups RCA CORPORATION 16 June 1969 [26 June 1968 (2)] 30281/69 Heading H4J [Also in Divisions C4 and H1] A transducer has two contiguous regions of different semi-conductors, the two semi-conductors being chosen such that they respond differently in respect of their field-independent polarization to the input; the input here being mechanical stress. At least one of the semiconductors has piezoelectric properties. The presence of a PN junction between the two semiconductors is preferred, and such pressure transducers may be made for forward biased (current varying) operation, for reverse biased (capacitance varying) operation, for A.C. (rectifying) operation, or for forward biased light emitting (especially lasing) operation. An injection laser may have a PN junction between region of gallium phosphide and gallium arsenophosphide. A general pressure-sensitive device may have a flexible substrate of metal, glass, mica, alumina, beryllia, acrylic resin, or polyamide resin coated in turn with vapourdeposited layers of gold (electrode), tellurium (buffer layer to allow for the different crystal structure of the following layer), crystalline P-type selenium (which does not show a fieldindependent polarization), hexagonal N-type cadmium selenide, and aluminium (ohmic contact). The two semi-conductor layers may be either monocrystalline or macroscopically polycrystalline and are substantially epitaxial. Gold may be replaced by other metals of high work function-Ni, Ag, Bi, Cu. The cadmium selenide may be replaced by CdS, AsS, As 2 Se 3 , Sb 2 S 3  and Sb 2 Se 3 . The selenium layer is amorphous when deposited and crystallization is effected (and speeded up by the tellurium) by heating the layer in air before the deposition of the further layers. The transducer may be encapsulated. Two of these transducers may be used in a stereophonic pick-up cartridge (Fig. 4) which has a rigid plastics frame 21 upon which the stylus 24 is carried by a flexible arm 25 (not shown in Fig. 4), the stylus movement being linked to the flexible substrates 2 of the transducers 1 by an elastomeric yoke 26, for example of rubber.
