Patent GB-959777-A (GB)
Title: Improvements in or relating to transistor current switching apparatus
IPC: H03K17/14
Filed: 1960-08-19
Abstract: 959,777. Transistor timing circuits. A. KUCKENS. Aug. 19, 1960 [Sept. 23, 1959], No. 28857/60. Heading H3T. [Also in Division G1] A transistor unit for operating a switching device for a given time comprises a normally charged capacitor which upon closing a switch causes a transistor to be cutoff until the capacitor has discharged, the transistor being coupled to a second transistor which conducts when the first is non-conducting and so operates a switch. In Fig. 5, transistor 17 normally conducts due to the current through resistors 5, 5<SP>1</SP> and 6 and a capacitor 4 is charged through a resistor 7. On making a contact such as 105 the potential at point A is brought to the reference potential and transistor 17 is cut-off so that a relay 3 is operated. The capacitor 4 however discharges through resistors 5, 5<SP>1</SP> and 6 so that after a time delay transistor 17 again becomes conducting and relay 3 released. A contact of relay 3 such as 104 may be connected across terminals A and B so that the timing sequence will occur even if contact 105 is only momentarily made. The relay is also operable by shining a light on a photodiode 103 so as to produce a pulse at terminal A, a condenser 102 preventing slow changes in the lighting from operating the circuit. The circuit may be operated by a sudden decrease in lighting if the photodiode 103 and resistor 101 are interchanged in position. Stabilization of the operation is obtained by maintaining the two transistors at the same temperature as by embedding them in synthetic resin of high heat-conductivity. The points A, B and C may alternatively be connected to a circuit such as is shown in Fig. 6 comprising two photodiodes 103 and 106. These diodes are arranged in a balanced bridge circuit so that variations, such as those due to temperature, are cancelled out. If diode 106 is shaded it may be arranged that the change in voltage across 103 at dusk causes transistor 109 to conduct and produce an output at A. Alternatively, if 103 is shaded the diode 106 may operate the circuit at dawn. Fig. 7 shows a sequence timer in which the momentary operation of a switch causes relay 3 to operate. This steps on a contact 33 so that capacitors 4 commences to charge, the charging current causing transistor 2 to be conducting and causing the relay 3 to be released. When capacitor 4 is charged transistor 2 becomes non-conducting and relay 3 is operated so that the switch 33 steps on one further position. Transistor 2 now remains cut-off until the charge on condenser 4 has returned to its original discharged condition when the transistor again conducts. Thus the relay may be made to operate and release intermittently at predetermined intervals. It is stated that the circuit may be arranged to recycle when the first sequence is complete. In an alternative embodiment (Fig. 4, not shown), the circuit automatically goes through a sequence of cycles on switching on the starting circuit and without the operation of switch F.

Filed: 1968-06-18
Abstract: 1,236,633. Foamed plastics laminates. A. A. CANDEL. 18 June, 1968, No. 28873/68. Heading B5N. A non-woven laminate comprises a base layer of elastic foamed plastics material covered on at least one face by a layer of flexible material of crimped or crinkled appearance, such crimping having been produced by bonding the base and cover whilst the base is under elastic tension and the cover is free of internal stress and then releasing the tension to crimp the cover. Both faces of the foam base may be so covered, either simultaneously or successively, or the second face may be covered by conventional means. The foam may be polyurethane and the covering material may be cellulose wadding, paper, plastics or fabric. In examples, foam base is unwound from a brake roller so that it is under elastic tension, and covering material is applied thereto, the foam surface having been rendered adhesive by heat-treatment. The material is calendered at 15‹ C. and 2 kg./cm.<SP>2</SP> and wound in a slack manner on to a roller. In the case where both surfaces of the base are covered, successively, the tension applied to the base may be different in each case; also, the tension applied may be varied in a discontinuous or gradual manner.

Title: Improvements in or relating to tool location in automatically controlled machine tools
Inventor: WILLIAMSON DAVID THEODORE NELS
IPC: B23Q17/22
Filed: 1962-07-27
Abstract: 1,035,197. Machine tool details. D. T. N. WILLIAMSON, and MOLINS ORGANISATION Ltd. July 26, 1963 [July 27, 1962; April 26, 1963], Nos. 28962/62 and 16544/63. Headings B3B and B3K. A method of locating a cutting tool T in numerically-controlled machine tool (e.g. by punched or magnetic tape) consists in releasing the grip on the tool within a chuck, moving the tool against a reference surface 118 and then reclamping the tool. Two tools 107, T are carried on a slide 102 movable on a slide 105. Two workpieces are carried on a vertically-movable slide 113 which also carries two reference pads 117, 118 and a tool storage rack 114. Axial play of the spindle 3, Fig. 3, is prevented by springs 9 between a collar 7 and a bearing 5. Oil-mist lubrication is supplied through passages 15, 16, 30. The spindle is rotated by a Pelton wheel driven by an oil jet. The rack 114 contains spring-pressed plastic holders which have thin-walled extensions to grip the cutting-ends of the stored tools. A plastic cover extending over all the tools is lifted when the slide 113 is lowered for tool-changing. In operation, each spindle 2, 109 (only one of which is subsequently referred to) moves to lie opposite a required tool as the slide 113 is lowered. Pressure is admitted to passages 68, 67 and a cylinder 60 moves forwardly to abut a collar 26; the pressure is then sufficient to overcome the force of a spring 73 so that a piston 54 then moves rearwardly. During the movement of the piston 54, pins 57 on the piston engage a ring 61 and carry back a rod 52 and a piston 49. Withdrawal of the piston 49 releases a conicallyended collet 36 and allows a split sleeve 39 to expand. The spindle is next advanced to pick up a tool, the advance being determined by a tape instruction. The spindle 3 is rotated slowly until a projection 43 in the end of the tool engages a recess in a spring-pressed plunger 44. The tool is then clamped by admitting pressure behind the piston 54 to release the rod 52 and allow springs 51 to close the collet 36. The slide 106 is then withdrawn, the slide 113 is raised, the slide 105 is moved sideways and the slide 106 again advanced. As the slide advances, the tool is unclamped and engages the reference pad 118. The slide stops at a tape-determined position. As the tool has been moved into the chuck, the rod 52 has moved a rod 76 to move arms 78 around a pivot 79. If the correct tool has been selected, one of two switches 80 is actuated: if a toolong or too-short tool has been selected, neither, or both, of the switches 80 are actuated and the machine stops. In a modification, the slide 113 is replaced by a rotary table, the cutter head can be swivelled, and only one tool is provided. The first Provisional Specification describes also a holster secured by a bayonet joint and carrying a spring-fingered toolholder, a bellows-shaped chuck and a toolejector.
