Title: Improvements in or relating to water closets
IPC: E03D5/02
Filed: 1958-08-08
Abstract: 902,871. Sanitary closets. LILJENDAHL S. A. J. Aug. 8, 1958 [Aug. 16, 1957], No. 25548/58. Class 26. In a water-closet assembly comprising a bowl 20 with a bottom outlet normally closedoff by a valve 22 which is intermittently operable to be open to discharge the bowl and a mechanism 31 to control the operation of the valve 22, so as to open it and reclose it after the lapse of a predetermined period of time, the outlet is connectible through a waste conduit 23 to a source of vacuum to promote discharging and the mechanism 31 is associated with an interlocking device influenced by the vacuum existing behind the valve 22 so as to prevent initiation of the mechanism 31 if the vacuum is less than a predetermined value. The mechanism 31 also controls a supply of pressurized water through a valve 27 to flush the bowl 20, is power-driven and is initiated manually by a knob 37. In one form shown, Figs. 1 and 8, the interlocking device comprises a cylinder 75 in a valve device 35 connected to the waste conduit 23 (through a pipe 34) in which slides a piston 74 associated with an interlocking element 73, drawn into the cylinder 75 against the action of a restoring force into a position in which the interlocking element 73 is inactive when a sufficient vacuum is reached in the conduit 23. The mechanism 31 is associated with a fluidoperated motor 32, 33 started by opening an actuating valve 72 in the fluid-supply conduit 34 thereto, the interlocking element 73 in its active position locking the actuating valve 72 positively in the closed position and closing off the conduit 34. In another form, Figs. 9 and 12, a separate conduit 95 is connected between the tank 25 and a modified control valve device 96 acting to evacuate the cylinder 33. To block the valve device 96 should the vacuum behind the valve 22 decrease below a predetermined value, a pressure-responsive mechanism 97 is connected with the waste conduit 23 through a pipe 98. The manual operating means for initiation is also modified, a knob 37 being on a spindle 97, joined to a lever 103 attached at one end to an extension 106 of the spindle 107 of the valve 72 and at the other end to a rod 108 which is part of means whereby the mechanism 31 will not operate unless the valve 22 is closed. The mechanism 97 comprises a cylinder 113 receiving a plunger 114 associated with a control rod 115 entering a hole 116 in the extension 106 with a low vacuum to lock the valve 72, assisted by an attached frame member 117 and a weighted wire 118. Specifications 867,664, 902,872, 902,873 and 902,874 are referred to.

Title: Circuit arrangement to compare two information items
IPC: G06F7/02
Filed: 1965-06-18
Abstract: 1,091,514. Comparators. INTERNATIONAL STANDARD ELECTRIC CORPORATION. June 18, 1965 [June 20, 1964 (2)], No. 25867/65. Heading G4M. A comparator has two cores per bit place of one binary comparand, each comparand being presented over a respective set of leads including a 1 lead and a 0 lead for each bit, the leads threading the cores. In a first embodiment, twelve leads carrying signals representing two 3-bit numbers in true and complement form are threaded through six magnetic cores as follows. The true lead of a given bit of one number threads in one sense a core which is threaded in the other sense by the complement lead of the correspondng bit in the other number. The same statement is also true with the words " true " and " complement " interchanged. Accordingly, if the numbers are equal, all cores are saturated in one direction or the other, and a pulse applied to a supervisory winding threading all the cores meets a low impedance and therefore emerges to actuate an indicator. Correct operation is monitored by applying the pulse with no numbers applied, a further winding threaded through all the cores in alternating senses delivering a signal in the case of malfunction. In a second embodiment, a pulse is applied to a winding on one of two respective cores for each bit of one number, a short-circuit having been completed in a winding on one of the two cores according to the corresponding bit of the second number. If the two numbers are equal, each core which the pulse attempts to switch has a short-circuited winding so no pulse is induced in an output winding threading all the cores. As a modification, one of two cores can be saturated for each bit of the second number, then application of the pulse will switch no cores if the numbers are equal.

Title: Improvements in or relating to press brakes and similar machines
Inventor: ASHLEY ALLAN
IPC: G05G13/00
Filed: 1948-10-13
Abstract: 650,234. Starting and stopping gear. VICKERS-ARMSTRONGS, Ltd. Oct. 13, 1948, No. 26673. [Class 80(ii)] [Also in Groups XXVI and XXXVII] Starting and stopping gear for a press is controlled by a lever 6 on a pivot 4, the outer end of the lever being connected to a treadle while its inner end carries a spring-pressed pawl 8 coacting with the inner end of a lever 5 on the same pivot 4, the outer end of the lever 5 being connected to the starting and stopping means, e.g. a clutch or electric switch or throttle valve and a brake. A second pawl 13 is mounted on a fixed pivot pivot 14, and a hand-lever 17, pivoted at 18 and carrying a pin 19 adapted to be engaged in any one of three holes 20, 20a, 20b, pivotally carries one end of a link 22, the other end 23 of which is controlled by cam means driven by the press. With the pin 19 engaged in hole 20, as in Fig. 1, depression of the treadle causes the inner end of lever 5 to be raised, by means of pawl 8, to a position in which it is held by the pawl 13, irrespective of whether the treadle is released or not. The machine is thus started and runs until the link 22 moves so that a part 22b depresses an arm 13a of pawl 13 (and also, if'treadle has not been released, an arm 8a of pawl 8) so as to release the lever 5, which returns to initial position, stopping the machine. With the pin 19 engaged in hole 20a, Fig. 5, a part 17a of the lever 17 engages a part 13b of the pawl 13 so as to displace the latter and render it incapable of holding the lever 5. The machine is started by depression of the treadle but may now be stopped at any time by release of the treadle, the machine being in any case finally stopped by the action of the link 22 in tripping the pawl 8. With the handle in the third position, in which the pin 19 is engaged in the hole 20b, the pawl 15 is again held inoperative but the link 22 is also displaced laterally so that it cannot contact the pawl 8, so that the machine continues to run so long as the treadle is depressed.
