Abstract: 1,053,343. Thread-tying in winding machines. W. REINERS. Aug. 30, 1963 [Sept. 1, 1962], No. 34405/63. Heading D1J. In a thread winding machine having a thread tying device and a test device for checking the strength of the tied thread means are also provided which operate in the event of unsuccessful thread tying to remove the thread parts from the tying device. Two threads 1, 2 (Fig. 3 not shown) clamped in clips 3, 4 are tied by-tying beaks 12, 13 the operation of which is initiated by rotation of a cam plate 6. A second rotating cam plate 7 actuates the thread testing plunger 5, movement of which is limited by the thread if a correctly formed knot has been made; otherwise the plunger 5 continues its movement causing electrical contacts 16, 17 to close and thereby to operate electromagnetic cutting means 20, 27. A suction nozzle 21 removes the severed thread end from the vicinity of the thread tying device. Similar severing and removing devices may be mounted for the thread 2 leading to the take-up spool if required. The contacts 16, 17 may be linked with counting means which serve to limit the number of thread tying attempts.

Abstract: 1305026 Vehicle lighting systems JOSEPH LUCAS (INDUSTRIES) Ltd 16 June 1970 [15 July 1969] 35484/69 Heading H2H  An electrical system for a trailer vehicle includes means for sensing the battery voltage, and adjusting a selecting circuit so that trailer lamps &c. are suitable for the tractor battery. If the tractor battery is a 24 volt battery, Zener diode 29 breaks down, and causes transistor 32 to conduct. The voltage across Zener diode 34 is then insufficient to cause it to break down, and transistor 36 is therefore non conducting. Thus no current passes through relay coil 16. In these circumstances the relay contacts 16a and 16b are in the condition shown in the Figure, and 24 volt flasher lamps 42 and 43 are connected to the terminals 11 and 12, half the voltage to stop lamps 46 and 47 is dropped across resistors 44 and 45, and half the voltage to lamps 49 is dropped across resistor 48. If the tractor battery voltage is 12 volts, the Zener diode 29 does not break down and so transistor 32 does not conduct. The voltage developed across Zener diode 34 is then sufficient to cause it to break down and switch transistor 36 on, this causes a current to pass through relay coil 16. Relay contact 16a is therefore closed and energizes relay coil 17, 18 and 19 causing relay contacts 17a, 18a and 19a to change state. This switches 12 volt lamps 43a and 42a, and causes 12 volts to be applied to lamps 46, 47 and 49.

Abstract: 1336846 Semi-conductor devices MULLARD Ltd 4 Nov 1970 [19 Nov 1969] 52474/70 Divided out of 1336845 Heading HlK The invention concerns a method of manufacturing an electric component, in particular a semi-conductor device, by forming a metal layer on a substrate and bombarding the layer with ions so that atoms from the layer are knocked-on and implanted in the substrate, at least part of the metal layer being retained in the manufactured component as an electrical contact for the implanted region of the substrate. Fig. 19 illustrates the application of the invention to the improvement of the electrical contact between two Al layers 84, 85 in a multi-level electrode structure on a Si body 80. Al atoms from the upper layer 85 are knocked-on by Ar ions to penetrate a contaminating alumina layer on the lower layer 83 and thereby to form an intimate contact therewith. In all the other embodiments the substrate into which implantation occurs is a semi-conductor body, and the descriptions of the manufacture of a PN junction diode, a PN junction radiation detector, a Schottky barrier diode and integrated circuits employing air-isolation, reverse-biased PN junction isolation and dielectric isolation are substantially as contained in the complete Specifications of co-pending Specification 1,336,845. The description of the manufacture of an IGFET is similar to that in the copending application, but in the present case the bombarding ions may themselves be acceptors and may be implanted to locally enhance the conductivity of the source and drain regions. Certain other modifications of the method of the copending application arise from this variation. Junction-gate FET manufacture is also referred to. Figs. 9-13, 14-17 and 20 (not shown) respectively illustrate three alternative applications of the invention to the manufacture of discrete bipolar transistors. In the first of these applications Sb ions are used both to knock-on Al atoms from a layer (48) into a Si body (41) to form the base region and also for direct implantation into the Si to form the emitter region (49). In the second application a large area Al layer (64) is applied over a localized Sb layer (63) so that on bombardment with inert ions Sb is knocked-on to form the emitter region while Al is knocked-on to form the base region. In the third application P ions are implanted into a P type Si body (90) to form a base region, the ions at the same time causing knock-on of Al atoms from a layer (98) to form the emitter region. Optionally Sb atoms may simultaneously be knocked-on to form a high conductivity base contact region at the surface of the implanted base region. Reference has been directed by the Comptroller to Specifications 1,239,043 and 1,239,044.
