Filed: 1947-09-08
Abstract: 639,591. Transformers and inductances. STANDARD TELEPHONES & CABLES, Ltd. Sept. 8, 1947, No. 24654. [Class 38 (ii)] An inductive electrical winding comprises a flat insulating disc A, of impregnated paper, fabric or plastic material, with a plurality of uniplanar of conducting metallic track B printed or deposited thereon and at the centre a hole D provided for the insertion of a magnetic core. One end of the track B terminates radially on a tag C, the other end in a raised contact portion E. The tag C is bent over as at G (Fig. 3) so that when a number of discs with metallic tracks and insulating discs are assembled to form an inductance the outer end of the conductor of the first disc makes contact through a hole in the insulating disc with the inner end of the conductor of the next disc to form a continuous winding. The stack of discs is then heat and pressure moulded to a central form and the central hole may accommodate a magnetic core. Various arrangements of sets of discs and wiring therebetween may be used to form a transformer. An alternative embodiment shows a winding unit in which a narrow strip of insulating material has a metallic conductor deposited or printed along one side of it and then wound into a tight spiral on a mandrel so that a hole is formed which may house a magnetic core. Specifications 569,388, [Group II], and 475,964 are referred to.

Filed: 1958-08-06
Abstract: 904,944. Insulators. BRITISH INSULATED CALLENDER'S CABLES Ltd. Aug. 5, 1959 [Aug. 6, 1958; May 29, 1959], Nos. 25254/58 and 18321/59. Class 36. A section insulator for an overhead traction system comprises at least two horizontally-spaced runners 2, each of which is composed of an insulating portion 5 uniting two metal end portions 3 and 4, the runners being attached at each of their ends to the end of a contact wire 1 by end fittings 6 and 7 and being so disposed that a metal end part 3 of one runner overlaps that metal end part 3 of a second runner which lies at the opposite end of the section insulator. The metal end portions 3 and 4 of the runners may be of inverted T section, the flange being cut away where necessary to permit bolting to the end fittings 6 and 7, and also to the insulating portions 5 by means of metal fittings 35. Alternatively the metal end portions may be of rectangular, tubular, or of other section. The insulators 5 are preferably resin-bonded glass or other inorganic fibre rods or tubes with a coating of a fluorocarbon resin, the fittings 35 being compression-jointed to them after cutting back the coating in stepped fashion, the end of the fitting 35 having a corresponding stepped bore (Fig. 8, not shown). Alternatively, if the end fittings are tubular, the glass fibre rod may pass right along the length thereof, being compression-jointed at the ends. In any case the external dimensions of the glass fibre rod and the fitting are such that the combination presents a smooth running surface for a travelling collector. The end fittings 6 (Fig. 4) are provided with a shaped groove in the underside to secure a profiled conductor which is locked by screws 18 (Fig. 2) set at 60 degrees. The runners are clamped on to the threaded ends of shaped studs which pass through holes 21 and have a cut-away central portion to allow passage of the end of the conductor wire 1 (Fig. 6, not shown). The clamp 7 which secures the outer ends of the runners to the contact wire 1 is formed. in two parts which, when bolted together, define an internal grooved profile to correspond with that of the contact wire. In an alternative form of insulator (Figs. 9 and 10, not shown) the runners are spaced apart and supported at the centre of the insulator from a tranverse bar of coated, resin-bonded fibre glass from the ends of which depend steady arms to which the runners are attached. In a further modification (Figs. 11 and 12, not shown) three runners are provided: two outer ones having their insulating portions at one end of the insulator and a centre one disposed the opposite way. The outer runners are carried by a metal arm which bridges the centre runner.

Abstract: 1349275 Transistor circuits; pulse amplitude modulation SIEMENS AG 19 April 1971 [25 March 1970] 25539/71 Headings H3T and H4L [Also in Division G1] In a circuit arrangement for producing current pulses of which the amplitude is dependent on the magnitude of a reference voltage, a series circuit comprises the emitter-collector path of a transistor 1 and first and second resistances 5 and 10 connected one on either side of the collectoremitter path, the second resistance 10 is lower in value than the first resistance 5 at least in the ratio 1 : 2, the base of the transistor 1 is connectable to a point of constant potential through a switching device 2 when the device 2 receives pulses and a further device 3, arranged to operate as a forward biased diode, is connected between the base of the transistor 1 and a point 8 for receiving the reference voltage and the further device 3 is arranged so that in operation the voltage across it varies with temperature in a similar manner to the base and emitter voltage of the transistor. Positive pulses applied at 9 to a transistor 2 cause the transistor 1 to conduct and produce current pulses i in the load 5. The amplitude of these pulses depends on the rereference voltage applied between 7 and 8. The current pulses i may be maintained constant independent of temperature or the amplitude of these pulses may be regulated depending on the temperature or depending on another quantity. Variations in the base-emitter voltage of the transistor 1 due to temperature are stabilized by a forward biased diode (6, Fig. 1, not shown) or as shown the emitter-base junction of a transistor 3 which is accommodated in the same housing as the transistor 1. As shown the amplitude of the current pulses i is regulated depending on temperature by a reference voltage obtained from a diode 12 which acts as a temperature responsive resistor. This circuit may be used as a current driver for providing inhibit current pulses to the inhibit line of a matrix store.

Title: Improvements in or relating to overload release clutch mechanism and electrically driven apparatus comprising a plurality of such mechanisms
IPC: G05G15/00
Filed: 1948-10-01
Abstract: 653,762. Overload-release clutches. PHILIPS ELECTRICAL, Ltd. Oct. 1, 1948, No. 25620. Convention date, Oct. 4, 1947. [Class 80(ii)] An overload release clutch, which re-engages automatically when the overload is cleared, comprises a floating intermediate member 4, drivingly connected by a pawl 8 to a driving ratchet-wheel 3; by a torqueresponsive tension spring 11 to a driven wheel 5; and by a one-way jamming roller 14 to an arresting member 6 which holds the intermediate member 4 in a stationary declutched condition during overload and itself has a tongue-and-slot limited connection 16 with a fixed member 17, whereby on overload-release the arresting member makes a limited backward movement which may be used for opening or closing a switch 19 in the circuit e.g. of the driving motor or of signalling apparatus, or for mechanically operating signalling: counting or hydraulic apparatus. The intermediate member 4 carries the pawl 8 on a pivot-pin 7 passing through an arcuate slot 13 in the driven wheel 5 to permit limited turning movement between the members 4, 5, by which movement the pawl 8 is pivoted into and out of engagement with the driving ratchet-wheel 3 by thrust against a pawl-recess 22 of one or other radially projecting end of a single-turn spring 20 carried in a circular recess 21 in the driven wheel 5. The pawl 8, which is as described in Specification 648,555, is channel-shaped and engages the driving ratchet 3 through a roller 9 pressed by a spring 10. Normal drive, Fig. 2, in the direction of the arrow P, passes from the driving ratchet 3, through the pawl 8, intermediate member 4, and tension-spring 11, to the driven wheel 5, the pawl 8 being pressed down into engagement by the left end (Fig. 2), of the circular spring 20. Overload causes the driven wheel 5 to lag behind, stretching the tension-spring 11 until eventually the other end (right, Fig. 2), of the circular spring 20 lifts the pawl 8 off the driving ratchet 3, thus disengaging' the clutch. The intermediate member 4 is now free to execute a limited movement backwards relatively to the driven wheel 5 under the influence of the tension-spring 11, during which movement the jamming roller 14 engages and turns the arresting- member 6 to the limit of its backward movement, opening the motor-switch 19. When the overload is cleared the tensionspring 11 returns the parts to the clutchengaged position Fig. 2, the arresting-member 6 being returned by the switch-spring or by an additional spring. One or more of these clutches may be used to permit arresting one or more shafts in predetermined positions, e.g. for tuning radio. Specification 634,781 also is referred to.
