Title: System for automatically stopping a guided moving body at desired positions
IPC: G05D3/20
Filed: 1972-07-21
Abstract: 1400281 Automatic control of movement LANSING BAGNALL Ltd 21 July 1972 [23 July 1971] 34342/72 Heading G3N [Also in Division H3] In a system for controlling the movement of the forks of a fork-lift truck to a desired position within any one of a plurality of possible non- contiguous stop zones, the actual position of the forks is digitally encoded by two disc encoders [Division H3], one of which is geared to make not more than one revolution for the complete range of movement and signals which stop zone the forks are in and the other of which signals unambiguously the position of the forks within the stop zone. The stop zones may be of unequal size and unequal spacing. The zone encoder, Fig. 3 (not shown), is divided into as many sectors as there are zones and has three information tracks co-operating with, respective photo-electric devices. The outer track gives a binary signal denoting the sector, the next signals the occupation of a stop zone, and the innermost carries marks extending further than the zones to signal the approach to a zone for slowing the movement of the forks. The system has pushbuttons 32 for selecting a desired aisle, a warning light 33 indicating when the truck is not in the right aisle, as detected by photo-cells 30 co-operating with fixed, aisle-identifying marks. The required bay is selected by pushbuttons 24, the bays being detected as they are passed by photo-cells 20, 21 and counted at 22, indicator lights 26 showing whether the required bay is ahead, has been reached, or is behind. The height to which the forks are to be moved are selected by pushbuttons 36a, 36b according to whether there is to be stacking or destacking. Over-riding manual "lift", "stop" and "raise" buttons 41, 42, 43 are provided.

Abstract: 1,006,556. Cathode-ray storage tubes. RAYTHEON CO. Sept. 27, 1961, No. 34588/61. Heading H1D. [Also in Division H4] In signal storage apparatus, the potential of the cathode-ray tube storage screen is varied in synchronism with the scanning thereof by a modulated electron beam, in such a way that in regions of the scanning pattern where the scanning lines are relatively closely spaced, e.g. in the centre of a P.P.I. radar scan, the writing sensitivity of the screen is lower than in regions where the scanning lines are more widely spaced. In particular, the storage surface 42 may be stabilized at cathode potential, and during writing, a saw-tooth waveform may be applied to screen 44 to raise its potential during each radial line scan from a lower limit just above the critical potential at which the secondary emission ratio is unity, to an upper limit giving maximum sensitivity. As shown, the storage tube comprises a perforated storage screen, a decelerating electrode 35, and a collector electrode 32 which may be replaced by a fluorescent screen.

Abstract: 447,534. Discharge apparatus. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN, Emmasingel, Eindhoven, Holland. Dec. 14, 1935, No. 34788. Convention date, Jan. 11.

Preferably, at least two points of support are provided in each of at least two transverse planes. In the form shown, a lamp 1 is supported within an outer envelope 2 by three helical springs 14 in each of two transverse planes, the points of support in the two planes having a mutual angular displacement with respect to the lamp axis.

Patent GB-1011079-A (GB)
Title: Electrical computer circuit
IPC: G05B19/18
Filed: 1963-02-08
Abstract: 1,011,079. Electric analogue calculating circuits. CINCINNATI MILLING MACHINE CO. Feb. 8, 1963 [Feb. 26, 1962], No. 34782/64. Divided out of 1,011,077. Heading G4G. [Also in Division H3] A circuit for computing the quotient of two variables comprises a current amplifying circuit having an input resistance across which is developed a signal proportional to a first variable function, the current amplifying circuit producing a D.C. flow through the input resistance directly proportional to a second variable function, the current amplifying circuit with its input resistance representing a high input impedance to A.C. flow. A variable impedance attenuating network is connected to a tap on the input resistance so that the A.C. signal developed across the input resistance proportional to the first function is varied in accordance with the D.C. flow proportional to the second function. Thus the A.C. potential across the input resistance is reduced as the direct input signal representing the second function is increased. The second variable will usually be represented by an alternating signal, which is converted to a D.C. by the full wave rectifier circuit of Fig. 3 and is positive going with respect to a steady negative potential of 18 V. From the output of the rectifier circuit the D.C. voltage is fed to the terminal 136 of the dividing circuit (Fig. 2) and is applied via the transistor 141 and Zener diode 142 to the base of a Darlington circuit consisting of the transistors 140 and 139. As the emitter of the transistor 141 goes more positive so does the base of the Darlington circuit and a more negative voltage appears at the collector of the circuit, i.e. on the lead 148. A coupling from the emitter of the transistor 139 in the Darlington circuit to the base of the transistor 141 provides negative feedback which ensures that the negative going potential changes on the lead 148 are directly proportional to the positive going changes at the input terminal 136. The A.C. proportional to the first variable is applied across the resistors R22, R19 (the Darlington circuit presents high impedance to the A.C. signal). In parallel with R19 are a number of resistor diode circuits 145, the positive ends of the diodes being connected to a resistor chain R23 energized from a negative terminal 147. The number of the circuits which conduct, and are therefore effectively in parallel with R19 is determined by the negative D.C. potential on line 148. The A.C. signal across R19 appearing on the line 148 is therefore attenuated by these circuit and will be attenuated in proportion to the D.C. signal corresponding to the second input variable. The circuit output at the terminal 146 thus represents the quotient of the first and second variables. This subject-matter is divided from Specification 1,011,077.

[Also in Division H2] A machine for shaping a terminal end of a conductor mounted on a dielectric base comprises, three relatively shiftable tool devices, means on the base forming part of the tool devices, the three tool devices comprising means for. forming in one cyclic operation a serpentine connector clip on the terminal end, and power means and control means for cycling the tool devices through an operating cycle. A preconstructed bridging connector 270 is placed in a groove 310 of a jig 218 and secured by spring clips 312, 314. The plastic body 290 of the connector may be trimmed to length 302 after shaping the terminal ends 296a-296c. The jigris placed on gusset blocks 220, 222 of a lower ram 152 and the terminal ends rest against alternate ones of mandrel studs 286, Fig. 10 (not shown). The extremities of the terminal ends are in contact with toothed abutments 276 of an upper ram 150. Pressure motors 112-118 are then actuated and the rams 150, 152 driven diagonally towards each other. The terminal ends are shaped. around protuberances 300, which are integral with the body 290 and around alternate studs 286. As the rams approach the ends of their strokes the extremities of the terminal ends contact the disengaged studs 286 and the abutments 276 enter between adjacent studs to form a reflex bend in each terminal end. The ram 152 has a shorter stroke than the ram 150 to permit the initial bend of the clip to be formed by the protuberance 300 without interference from the matching tooth 276. The protuberance may be slightly deformed during this final stage, but the initial bend has been fully formed at this stage and is not thereafter deformed by the tooth 276. The rams are then retracted, but owing to the shape of the formed spring clips, the connector piece 270 and the jig 218 remain stationary. The clips tend to spring back slightly as the rams withdraw and the operator removes the connector piece and jig by sliding the clips off the studs 286.
