Title: Improvements in and relating to washing machines
IPC: D06F34/30
Filed: 1965-07-12
Abstract: 1,091,368. Washing machines. PHILCOFORD CORPORATION. July 12, 1965 [July 13, 1964], No. 29528/65. Heading D1A. In a washing machine having programme control means which causes successive operations to be performed in successive timed intervals, sub-interval control means are operative in at least on programme to provide intermittent agitation of the fabrics or the like being washed instead of the continuous agitation peculiar to that interval during another programme. The washing machine 10 has a control dial 11 mounted on a back panel 12 with the push buttons 13 for selecting water temperatures and the like and programme selector push buttons 14, 15. The washing operations may be started and also manually accelerated or modified by turning the dial with knob 16. When push button 14 is depressed to initiate the blanket and woollen cycle and knob 16 is rotated slightly the fill solenoid F is energized and the drive motor circuit is left open. Filling continues until pressure switch PS is operated when timer motor T is started and contacts 7B and ST are closed in series with sub-interval switch SS, unless these contacts have already been closed by turning knob 16. Switch SS comprises a cam 18 with a lobe 19 driven by timer motor T and operating a lever 20 to open and close contacts SS periodically. When contacts SS are closed, they energize a relay R which shifts a linkage SRL to actuate switch S2 and energize motor M to cause tumbling during this subinterval, e.g. 10 seconds, the intervals between tumbling being, e.g. 12 seconds. During the subinterval operations, the lobe 22 of a cam 21, driven by motor T operates a pawl 23 to advance ratchet 24 by one tooth for every revolution and 20 turning the cams operating switches 5, 6, 7, 8 and 9. When the subinterval tumbling ceases the drive motor M is de-energized and the timer circuit is opened. The temperature control circuit is then closed to operate a water heater controlled by a temperature control unit TC to heat the wash water to the selected temperature. The timer is then re-energized and when contacts ST are closed another intermittent tumbling operation is performed after which there is a soaking operation without tumbling and then these two operations are repeated. Meanwhile although the contacts controlling the drain, rinse and spinning open and close, relay R being energized prevents these operations. The cycle is completed by removing the warm water, adding cold rinse water, soaking and extracting. The machine is drained and meanwhile subinterval tumbling takes place until the water level has dropped sufficiently to operate pressure switch PS when the machine goes into spin when switch SS closes. In the final main intervals spinning takes place. The machine also performs a normal wash cycle.

Title: Electrical two-part connector with releasable locking mechanism
IPC: H01R13/703
Filed: 1959-09-03
Abstract: 934,442. Two-part couplings. CANNON ELECTRIC CO. Sept. 3, 1959 [Sept. 25, 1958], No. 30081/59. Class 38 (1). A plug-and-socket connector comprising shells 16, 15 respectively enclosing pin-andsocket contact-carrying pairs of insulating blocks 25, 26 and 43, 44 has a releasable locking device 35 for securing the plug- and-socket members together. As shown, the socket member has a further pair of socket contact - carrying blocks 49 slidable on bolts 52 and spring- urged away from the blocks 43, 44 but which can be drawn towards the latter blocks by the locking device to engage the contacts 18 carried thereby with rearwardlyextending pins 48 on the contacts 19 carried by blocks 43, 44. The locking device comprises a screw-threaded socket 115 carried by the blocks 49 and engageable by a stud 111 having a stem 112 locked in the end of a tubular shaft 82, which extends through a barrel 36 carried by the plug member, by keys 108, Fig. 5, which are held in engagement with a groove 113 in stem 112 by cam surfaces 104 on the barrel. The shaft and barrel are movable relatively to each other either by means of a lanyard 125 attached to a collar 74 carried by the inner end of the barrel, or by fluid pressure acting on a piston 83 carried by the shaft and slidable in the collar 74. Thus the cam surfaces 104 may be withdrawn from locking engagement with the keys 108 to release the stud 111. In engaging the plug-and-socket members, the plug with the stud 111 locked thereto is engaged with the contacts 19 and the barrel 36 and shaft 82 are rotated by means of a knob 88, thereby causing the stud to draw the socket 115 and blocks 49 towards the blocks 43, 44 against the biasing springs to complete the circuit through the connector and at the same time lock the coupling members together. To release these, the stud 111 is unlocked as described above, either by the lanyard or fluid pressure, thus allowing the blocks 49 to retract and disengage contacts 18, 19 such movement being assisted by a spring-loaded rod 101 in the shaft 82. The plug member may then be removed leaving the stud attached to the socket member from which it may be subsequently removed when the members are to be re-connected. The blocks 49 and further set of socket contacts 18 may be omitted in which case the socket 115 will be carried by the blocks 43, 44 and release of the locking device will cause the rod 101 to eject the plug member from the socket member.
