Abstract: 1444001 Repeater power supply WESTERN ELECTRIC CO Inc 27 July 1973 [31 July 1972] 35941/73 Heading H4R [Also in Divisions G3 and H2] A pair of signal transmission lines 13, 14 having repeaters 11, 12 derive power from multiple regulation mode D.C.-D.C. converters 15 ... 18 (see Division H2). The converter outputs are normally regulated in response to the sum of output voltage and output current but have voltage regulation modes to prevent the voltage becoming excessive and current regulation modes to prevent the current becoming excessive. The mid-point between converters 16 and 18 is grounded; a relay 24 is provided to ground the mid-point between converters 15 and 17 under specified fault conditions. Fig. 4 shows the circuit associated with the mid-point between converters 15 and 17. The current between the converters is monitored across resistors 92, 93 and is compared by amplifier 96 with a reference 97. When the loop current falls below a threshold level, relay 98 will be de-energized, opening contacts 108, releasing relay 105 and closing contacts 24 which ground the floating point via resistor 102. The floating point voltage is monitored by a gas tube 101 and carbon block over-voltage protector 100 so as to operate amplifier 106 and close contacts 24 in the event of over-voltage.

Abstract: 1,106,669. Fire detection systems. PYROTECTOR Inc. 11 Aug., 1966, No. 36065/66. Heading G4N. [Also in Division G1] A power supply is connected so that radiation on one of a plurality of optical or smoke detection heads 10 causes a decrease in resistance of the head and a resulting increase of voltage at the base of transistor Q1, to actuate a fire alarm, through transistor Q2 and relay K1. To prevent a false alarm being given in the event of a short circuit occurring in one of the leads to or from detector heads 10, a third transistor Q3 is connected between the base of alarm actuating transistor Q2 and earth. A Zener diode ZD1, having a breakdown voltage greater than the voltage which appears at the base of transistor Q1 in the event of a fire, is connected between the emitter of transistor Q1 and the base of transistor Q3 to render the latter conductive in the event of a short circuit and thus to prevent actuation of transistor Q2.

[Class 74 (ii).] In knitting ladder-proof fabric, means is provided for relatively adjusting each wale thread guide and its associated needle to hold the wale thread in front of the ground thread loop, as the needle descends the stitch cam. Wale thread feeding means is described. Each thread guide in order is moved outwardly, deflected and retracted by cams 22, 26, 24 respectively. It is now again projected by a cam 23 to hold its thread in front of the ground thread loop, reaches its extreme position just as the needle has descended nearly to the bottom of the stitch cam, and is then retracted again by a cam 25 whilst the needle completes its descent. The cams 22, 23 and swinging levers 31,46 are fulcrummed on pins 30, 45 carried by a plate 29. At one end the levers carry pins 32, 47, which enter slots 33, 48, formed in slides 34, 49, and, at the other end, are engaged by stems 35, 43 upstanding from the ends of cams 22, 23, and passing through arcuate slots 37, 44 in plate 29. A pinion 39 effects engagement between racks 38, 41 formed on slides 34, 42. A pin 50, fixed to the slide 49, is engaged by one end of a lever 52, pivoted at 53, and having a pin 54 at its opposite end. To put the wale thread guides out of action, an external abutment (e.g. 55) is made to engage slide 42 and the pin 54. To bring the cams into operation the abutment is made to engage a pin 51 on the slide 34, and the pin 50. The bobbins 16, are supported by their flanges on a channelled support 17. Wire droppers 21 pivotally mounted on the axis of the guide pulleys 20 take up slack. Specifioations 364,039, 364,108, 376,350, 393,314, and 394,708 are referred to.

Abstract: 1,026,360. Washing machines. HOLZER PATENT A.G. Sept. 4, 1964 [Sept. 4, 1963; Sept. 11, 1963], No. 36468/64. Heading D1A. [Also in Division H2] In a washing machine, the programme is set by switching means mounted behind a moisture impervious panel 3 and operated from outside through the control panel. As shown, Fig. 1, in a cavity 2, sealed against moisture by a magnetically neutral panel 3, there are switches 5, 6, 7, 8 connected respectively to the contacts 9, 10, 11, 12 of programme switch 13, the other contacts being connected to feed wire 20. A switching arm 15 engages contacts 9, 10, 11, 12 and is connected through relay 16 to bus bar 19 and controls a bridging contact 17 of the control circuit of motor 18, which drives switch 13 through hunting and stepping gearing 21. Armatures 23 on switches 5, 6, 7, 8 are attracted by a permanent magnet 22 outside panel 3 to close the switch corresponding to the programme required. If switch 7 is closed and motor 18 is started manually, arm 15 moves rapidly across contacts 9 and 10 and on reaching contact 11 it breaks the motor control circuit at 17 so that the motor operates by slow step motion and the corresponding washing programme is carried out. In a modification, contact 17 is magnetically operated and arm 15 switches small control lamps. In a further modification, several magnets may be provided so that several switches may be closed to select a programme. Magnets may be mounted on a plate which is placed in different positions on the panel to select different programmes or the magnets may be mounted on a rotatable carrier. Armatures 23 may be magnetized and operated by pieces of metal. In an alternative arrangement, Fig. 5 (not shown), light sensitive switching cells 31, 32, 33, 34 are arranged in series, the control panel is partly transparent and a partly shadable light source is arranged outside it. Cell 31 is connected to supply line 35, cell 34 is connected through relay 36 to supply line 37 and the normally closed contacts 38, 39 control the current supply from line 37 to line 40 connected to the ends of switching relays 41, 42, 43 which are connected to the leads between cells 31, 32, 33, 34 and control programme selector contacts 44, 45, 46. In a modification, one light sensitive cell 53 is provided which, when shaded, starts motor 57 to cause the rotation of an arm 56 which engages successively the contacts of a switch 54 connected to programme selection relays 41, 42, 43, 51 each connected to a lamp 55. When the appropriate lamp lights up, the shading is removed from cell 53, motor 57 stops and the appropriate programme proceeds.
