Abstract: 1,245,326. Machinery safety devices. CANDY S.p.A. 2 Dec., 1969 [17 Dec., 1968], No. 58844/69. Heading F2J. In a timing device for a washing machine comprising an electric motor 4 which drives two groups of cams, a slow group 5 and a fast group 6, mounted upon a rotatable shaft 7 which carries a washing control hand knob 8 at its upper end, cams 14, 22 operate a latch device 29 which locks a door release push-button 32 for a predetermined interval of time after the normal cycle of the machine in order to prevent opening of the door during that interval of time. The slow cam 22 may be modified to enable the button 32 to be depressed during a phase when the drum is rotating slowly. In a modification shown in Fig. 17, an electromagnet 54, 61 operates a latch bar 64 having a ramp portion 77 which locks a rod 71 carrying a push-button 72 of a master cut-out and also having a portion 75 which engages an aperture in a rod 31 carrying push-button 32, thus preventing unlocking of the door of the washing machine. At the end of the centrifugal phase, a protrusion 50 of slow cam 22, Fig. 16, releases a follower 49 thereby breaking a contact 51 supplying power to the electromagnet coil 54.

Patent GB-2001763-A (GB)
Title: Electrochemical cell gas sensor
IPC: G01N27/49
Filed: 1978-07-21
Abstract: For sensing depolarising species in gases, especially for sensing carbon monoxide in air, for example in coal mines, an electrochemical cell has two electrodes of identical composition in the presence of an electrolyte, one of the electrodes being positioned so that an atmosphere to be sensed can diffuse to it. No voltage is applied across the electrodes, other than that resulting from the depolarising action of gas species in the atmosphere and the sensor current is measured. The sensor offers the possibility of manufacturing an easily portable instrument which is not subject to zero drift.

Patent GB-2018999-A (GB)
Title: Distance Measuring
IPC: G01D5/22
Filed: 1978-11-23
Abstract: A transducer arrangement is provided for measuring distances representing relative displacements between apparatus parts, particularly pistons and cylinders of hydraulic rams. A plug 30 may screw fit into a hydraulic ram cylinder end and houses an electromagnetic distance transducer 58 having a short range of operation with opposing applied biases from relatively strong and weak springs 40 and 52, respectively, between it and a part 54 which may be pinned to the interior of an axial bore through a piston and its rod assembly. The relatively weak spring 52 is constrained in a tubular sleeve 22 also to extend within a piston/piston rod bore. In operation, relatively large displacements of an apparatus part keyed to the part 54 will produce nearly proportionate smaller displacements of a transducer core 56 enabling the transducer 58 effectively to measure such large displacements accurately. <IMAGE>

Title: A fuel injection carburation system for an internal combustion engine
IPC: F02M69/04
Filed: 1979-07-12
Abstract: Fuel is passed into the inlet manifold 9 of an internal combustion engine 17 via a plurality of passages arranged in parallel, and each incorporating a respective electromagnetically operated valve 8. These passages are connected upstream of the valves 8 with a pipe 11 extending from a fuel pressure regulator 10, supplied with fuel from a tank 13 by a pump P, the regulator 10 serving to maintain the pressure difference between pipe 11 and injection zone 9a of manifold 9 at a constant value. Each valve 8 is opened and closed repeatedly at the same frequency, the frequency being proportional to the rate of air flow through the manifold as measured by sensor 4. However, the operation of each valve differs in phase from that of any of the others by a fraction p DIVIDED n of the period of the valve operating cycle, where p is an integer and n equals the number of valves. The system described allows accurate and highly reliable fuel supply over a wide range of engine operating conditions from idling to maximum speed. <IMAGE>
