Abstract: 1,145,525. Automatic speed control. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Nov. 2, 1967 [Nov. 22, 1966], No.52266/66. Heading G3R. [Also in Division H2] In a mine winder, motors 1, 2, are supplied in parallel from generator 3 whose field winding 4 is controlled by unit 5 which amplifies the result of comparing a reference signal with a signal derived from tachometer generator 8. The reference signal is derived from a potentiometer associated with a driver's lever and having an output circuit 6 connected to a ramp circuit 7 for changing the signal gradually. An auxiliary generator 9, which is connected to the motor 2, has its field winding 10 supplied from unit 11 in which the signal from unit 7 is compared with a signal representing the speed of the motor 2. The unit 11 is also controlled by a position error detector 13 which compares the outputs of selsyns 14, 15, each coupled to the respective motors, the output of the detector 13 being limited by unit 16. The units 5, 11, may be controlled additionally by limiters 17, 18, responsive to signals derived from current transformers 19, 20, the unit 18 being adapted to cut out one motor while the other motor continues to operate. Motor field windings 21, 22, are supplied through resistors 23, 24, from constant voltage source 25. The input to the detector 13 may be derived from floor level signals relating the positions of conveyances driven by the motors. The auxiliary generator 9 may be replaced by semiconductor rectifiers adapted to boost the operation of the motor 2 for lifting action only.

Rotation of the wheels 17 is transmitted by shafts 18A, 18B, and gearboxes 19 to the opposite ends of a rotary flow control shaft (not shown) within the seed hopper 8 of the sowing mechanism 9. Connected to the outlets of the seed hopper 8 are telescopic tubes 20. 20A feeding staggered sowing shoes 21 (Figs. 1 and 2), or hoses 47A (Fig. 3). The shoes 21 are fastened to arms 22, 23 which are pivoted to a removable beam 24 and are biased downwards by spring-loaded telescopic rods 25 by linkage 26-31 to a control lever 33 accessible to the tractor driver.

Patent GB-1397840-A (GB)
Title: Electronic switching module
IPC: H04Q11/04
Filed: 1972-11-30
Abstract: 1397840 Automatic exchange systems INTERNATIONAL STANDARD ELECTRIC CORP 30 Nov 1972 [2 Dec 1971] 55262/72 Heading H4K An integrated circuit cross-point switching matrix for interconnecting time multiplexed PCM channels comprises for each column of the matrix a control circuit consisting of a receive register RR0 into which the identity of a crosspoint gate-to-be-opened is entered over an address wire ad0, a buffer register RT0 into which the identity is transferred, and a decoding network dc00-dc07 for enabling the specified gate. A plurality of matrices may share the same column in which case a particular matrix i.e. a particular group of inlets E0-E7, is selected by actuating a matrix gate, e.g. CVD. The registers may be integrated circuits consisting of MOSFETS as depicted in Fig. 2. A bit applied to input ent during the presence of a short pulse phase #1 and an overlapping phase #2 (Fig. 3) is inverted and stored in capacitor Cp1. In similarly constituted phases #3, #4, it is reinverted and stored in capacitor Cp2. In Fig. 4 each box CH consists of a chain of 3 MOSFETS such as Q1-Q3 so that during the serial application of three bits to the circuit during a single phase cycle #1-#4 (i.e. #1, #2; #3, #4; #1, #2) the boxes CH3, CH4 and CH1 will store the first, second and third bits respectively each in inverted form. During subsequent phases #5, #6 the bits are reinverted and stored in boxes CH7-CH5 respectively from where they are decoded by the decoding circuits so as to enable the cross-point gate to which they correspond. An alternative embodiment using two MOSFETS in series between positive and negative battery terminals and an input MOSFET responsive to phase #2 signals is described with reference to Fig. 6 (not shown). Such a circuit when used on a register dispenses with one of the boxes CH1-CH4 but requires two boxes per each of CH5-CH7. The advantage lies in that the buffer register is now constituted by bi-stable circuits which provide the inverted and non-inverted versions of an input signal at all times.

Abstract: 1,248,750. Delivering sheets; cutting apparatus. JAGENBERG-WERKE A.G. 27 Nov., 1968 [8 Dec., 1967], No. 56322/68. Heading B8R. [Also in Division F2] Sheets leaving high speed conveyer belts 9, 10 and 11 are caused to overlap by transfer to a slower moving conveyer belt 13 which latter belt is driven through a differential arrangement 15 adapted to permit selective starting and stopping of the belts. The differential, Fig. 3, comprises a drive shaft 23 and two driven shafts 24 and 25, the latter being connected to roller 26 (of conveyer 13). Shafts 24 and 25 carry brake discs 27 and 28 which may be gripped by brake shoes 34, 35. A gap in the stream of sheets detected upstream of conveyer 13 causes shaft 25 to be braked and idler shaft 24 to be released, thus transferring the drive of shaft 23 from shaft 25 to shaft 24 and stopping belts 13 to permit closing of the gap. The sheets may be cut by rotary cutters 5 from a web 2 and fed over a table 7 to a magnetically controlled deflector 8 which diverts faulty sheets (as detected at 3) to supplementary pile 22. Good sheets are delivered in overlapping formation to pile 14. Photo-cell 12 detects gaps in the stream and delivers control pulses to the differential.

Filed: 1973-12-07
Abstract: 1459797 Cathode-ray storage tubes SONY CORP 7 Dec 1973 [8 Dec 1972] 56918/73 Heading H1D [Also in Division B6] A storage target for use in a tube having an electrical input and output, or in a camera tube, includes a conductive electrode 9 formed on a base 1a-e.g. the tube envelope-a storage material 10, and an electrode 12 in the form of spaced strips. For an electrical input tube, the layer 10 is of insulator, e.g. SiO or SiO 2 , formed as the oxidized surface of the chromium electrode 9, the electrode 11 being of aluminium. The tube includes a scanning electron gun and a beam landing adjusting grid (G 4 , Fig. 4, not shown). To erase the target and prepare it for uniting, the potential V T  of electrode 9 is held at 200 volts and that of electrode 12, V P , at 180 volts, whereby scanning the target with the electron beam gives a secondary electron emission ratio greater than unity and raises the insulator surface potential, V S , to 180 volts. To unite upon the target, V P  is raised to 220 volts, and the target scanned with the density modulated writing beam, to give V S  equal to 180 volts still over the unwritten areas, but 220 volts over the written areas, whereby although V S  varies over 40 volts, the potential difference across the insulator 10 does not exceed 20 volts. To read the target, V T  is set at - 20 volts and V P  at 10 volts, whereby the beam reaching the electrode 12 is modulated by the surface potential of the adjacent regions of insulator. In a modified target, Fig. 7, insulator 10 is of increased depth beneath the electrode 12, and a method of producing this structure by etching, without undue attack on the sidewalls of the depressions in the insulator, is disclosed (see Division B6), in which the insulator 10 is formed of three successive layers of MgF 2  or CaF 2 , of Al 2 O 3 , and of SiO 2 . Reference is also made to a target formed by applying electrodes to opposite surfaces of a thin glass plate. When employed as a camera tube, electrode 9 is transparent, and storage layer 10 is a photoconductor, the incidence of an optical image producing a corresponding pattern of potential V C  at the opposite surface of the photoconductor, again to modulate the receipt of a writing beam by the electrode 12; since charging and discharging currents are not employed in the read-out process, the latter may be repeated without image exhaustion.
