Title: Injection Moulding Machine
IPC: B29C45/53
Filed: 1967-10-04
Abstract: 1,171,307. Injection-moulding machines. GEORG SEIDL K.G. 4 Oct., 1967 [7 Oct., 1966], No. 45154/67. Heading B5A. An injection cylinder 1 has a unit 9 adjacent its outlet comprised by a number of pellets with passages therebetween for the flow of material forced into a mould 4 by a piston 2. Material is supplied to the injection cylinder from a cylinder 5 having a piston 6 and a similar assembly 8 of pellets. The units 8 and 9 effect a heating of the moulding material and a mixing of its ingredients. In the embodiment of Fig. 2 an injection cylinder 1, with a unit 9 of pellets, is rigidly attached to a main cylinder 21 by members 17, 18, and supplies, in turn, one of a series of moulds 4 arranged on a table to rotate past the cylinder. The latter is fed with moulding material from a cylinder 5 by means of a piston 6 having its rear portion 26 slidable in a housing 25 supplied with pressure medium through apertures 31 or 32. The material is fed to the cylinder 5 via a hopper 23 and passage 7, and reciprocation of the piston 6 forces it through a unit 8 of pellets into the injection cylinder. As the latter fills with material the cylinder 5 and its associated parts 14, 25 are forced back and are guided on the members 17, 18 until the assembly strikes an adjustable stop 36 whereupon the supply to the injection cylinder is interrupted, and pressure medium is supplied at 28 to the main cylinder 21. Such pressure medium acts on a piston 24 of the assembly to cause the piston 2 to force the material from the cylinder 1 into the mould. The apparatus is adjustable longitudinally and laterally on a support 35.

Title: Method of electrical fault indication
IPC: G06F3/147
Filed: 1975-10-31
Abstract: 1522810 Testing data processing equipment WESTINGHOUSE ELECTRIC CORP 31 Oct 1975 [8 Nov 1974] 45446/75 Heading G1U A method of monitoring for a fault in an apparatus which periodically produces coded output signals involves communicating the output signals to a decoder which provides a response when the correct coded signal is received, this response restarts a time signal nominally lasting for a predetermined time, and this time signal inhibits the generation of a fault indication. If the period between the emission of coded signals is shorter than the predetermined time, the fault indication is continuously inhibited. If the predetermined time is made slightly shorter than the period, the fault indicators will momentarily respond. The coded signals may be emitted in response to a master controller operating a test generator which contains stored test codes Fig. 1 (not shown), or may be emitted by a microprocessor used to monitor and  control an industrial process i.e. a nuclear reactor in which neutron flux is monitored. Preferably the coded signals are sequentially supplied in complementary pairs received over lines DATA 0-15 and DS1-5 in address and data form. After decoding 38-42, the reception of two correct codes in the correct order operates a bi-stable 48-54 to trigger paralleled monostables 56-58 to energize the fault relay thereby inhibiting the alarm.

Abstract: 1498099 Lemon slicing machine LEMONAID Ltd 23 Aug 1976 [6 Nov 1975]  46033/75 Heading A4C A slicing machine, e.g. for halved lemons, consists of a cassette 10 of semi-cylindrical shape and adapted to be rotated by location in a holder 5 rotated by an electric motor 20 via gearing 21 and belts 22, 23, the motor also rotating a blade 9 so that as the cassette is rotated the thickness of a lemon projecting beneath the open bottom end of the cassette is sliced off by the blade and falls through an opening 25 in a bottom tray 4. The machine may be operated continuously using a switch 26 or intermittently using a pivoted lever 6 which when momentarily contacted by a receptacle below opening 25 to receive a slice will pivot and cause its end 29 to close a micro-switch 30. This causes the holder 5 to rotate sufficiently to close a second micro-switch 31 which will energize the motor so that the cassette completes a single revolution, switch 31 co-operating in this respect with a cam 32 on holder 5. The cassette is held in holder 5 by a projection 18 on the former engaging a slot 17 in the latter. The slice thickness is determined by the position of a gauge plate 8 and a weight 24 forces the lemon halves downwards through the cassette. The motor may have an electromagnetic brake and a thermal cut-out.

Abstract: 1,154,863. Semi-conductor devices. TEXAS INSTRUMENTS Inc. 17 Oct., 1966 [20 Oct., 1965], No. 46249/66. Heading H1K. An integrated circuit comprises a number of monocrystalline semi-conductor bodies 11 embedded in a support 12 made of a glass having a working temperature above about 900‹ C. The bodies 11, which contain active or passive semiconductor components such as diffused transistors or resistors, are interconnected by leads extending across the support 12, which may also carry thin film resistors, and have only their upper surfaces exposed by the support 12. The various bodies 11 may be made of different semi-conductor materials such as Si, Ge, and/or GaAs pressed into the support 12, and in this way a temperature compensated integrated circuit may be provided. In the embodiment shown the bodies 11 initially comprise mesas etched in an Si wafer and covered with aluminasilica glass to form the support 12. The glass is applied by settling or centrifuging a mixture of glass particles and photoresist polymer. The polymer is developed to provide a temporary bond for the glass, and the assembly is heated to melt the glass and burn away the polymer. The wafer is then lapped or etched away, leaving only the mutually isolated mesa portions 11 embedded in the glass support 12, following which individual components are formed by diffusion into the portions 11 through oxide masks thereon. In an alternative method the semi-conductor bodies are separated by scribing a semi-conductor wafer mounted on a glass support, etching away the areas of the wafer which have been fractured by the scribing process, and pressing the remaining semiconductor material into the glass while heating the latter to its working point.
