Abstract: 1,099,762. Semi-conductor pulse dividing circuits. STANDARD TELEPHONES & CABLES Ltd. Oct. 21, 1966, No. 47147/66. Heading H3T. A digital divide by two circuit includes a resistance memory device RM1 which has a voltage-current characteristic as shown in Fig. 4. In Fig. 3 the device RM1 is biased in the low resistance condition at Q and a first negative input pulse P1 from a generator G changes the state of the device into the high resistance condition which it maintains when this pulse ends and is then biased at V B . The next negative input pulse P2 changes the state of the device to a low resistance condition biased at Q so that for every two input pulses one output pulse of voltage V B  is produced which may be filtered to produce a further output (Fig. 5C, not shown). In an alternative arrangement (Fig. 6, not shown), the output is taken across an additional resistor connected between the device and the earth connection. The device RM1 consists of a thin metalinsulator-metal sandwich which holds its high or low resistance condition to which it has been set for a delay or relaxation time, during which time input pulses applied to the device have no effect on its state. The D.C. source V s  may be applied intermittently so as to save on power supplied to the circuit.

Abstract: 1,171,914. Lighting control systems. THORN ELECTRONICS Ltd. 19 Oct., 1967 [21 Oct., 1966], No. 47340/66. Heading H2H. [Also in Division G3] The Specification relates to lighting control systems generally similar to those described in co-pending Specifications 1,171,915 and 1,171,916, but is primarily directed to the layout and functioning of the channel selector and the input scanner. As shown, the selector 13 comprises a " hundreds " register 50 and a " tens " register 51, both of which can be set by push-buttons (not shown) and which are connected to corresponding AND gates in respective matrices 52, 53, each gate also receiving an input from the corresponding " hundreds " and " tens " outputs of the divider circuit 16. The output 54, 55 of the matrices are connected to an AND gate 56 in turn connected to all the AND gates in the matrix 58 of the input scanner 22, each of the latter gates also receiving an input from a fader and an input from the unit register of the divider 16. Thus the fader outputs appear at terminal 59 for the range of channels selected by selector 13, the matrix 58 being duplicated to provide two output terminals respectively supplying " raise " and " dim " analogue signals from the faders. The channel selector may be modified according to the number of faders provided in the system, e.g. the channel selector may have " hundreds," " tens " and " units " if only one fader is present. Operation of the system for various numbers of faders is discussed. If a greater number of channels are required, the divider and channel selector are modified together with an increase in the master oscillator frequency or the time of the divider cycle. The Specification also describes an AND gate matrix, Fig. 4 (not shown), suitable for the file selector (35) of the lighting control system of Specification 1,171,916.

Title: Hydraulic device for turning an invertible plough

Abstract: 1474926 Reversible ploughs E HENGSTLER [trading as ERWIN HENGSTLER FABRIK HYDRAULISCHER HEBEZEUGE] 4 Nov 1974 [21 Dec 1973] 47551/74 Heading A1B  An invertible plough is reversed by the piston rod 6 of a double-acting ram 1 supplied from the tractor hydraulic system (not shown) through a pressure-dependent control unit 2 fitted to the ram head. Oil at a pressure of 40 to 90 bars, supplied through conduits 17, 16, depresses a slide valve 10, which opens a valve 13 and connects conduit 16 to an external conduit 36. Piston 43 is forced upwards and a valve 35 opens so that excess oil flows into chamber 32, and displaced oil flows back to the hydraulic oil supply (not shown) through valve 13 and conduits 30, 31. Near to the upper dead centre point, the bolt 24 closes conduit 34. This causes the pressure in conduit 16 to rise to a value of 150 to 180 bars, determined by a pressure limiting valve (not shown) in the tractor hydraulic system (not shown), which is sufficient to depress a changeover piston 11 slightly and to open a valve 12 which permits the full depression of piston 11. This connects conduit 29 to conduit 18 and to conduits 16, 17, and raises the slide valve 10, which in turn closes conduit 36 and valve 13 whilst opening conduit 48. Oil then flows through conduit 18 to open valve 19 and depress piston 43. At the same time valve 35 is closed, and chamber 33 is connected to the return conduit 31 via conduits 36 and 48, so that piston 43 moves down without counterpressure. Protection against premature opening of valve 12 by a high starting surge is provided by a spring-loaded damper piston 46. The rate of depression of piston 43 is controllable by adjustment of a constriction element 15 which partially blocks conduit 29.
