Title: Improvements in or relating to coupling devices for toothed or friction gearing
IPC: F02N15/06
Filed: 1932-04-28
Abstract: 388,253. Turning - gear. ECLIPSE MACHINE CO., Elmira, New York, U.S.A. April 28, 1932, No. 12236. Convention date, April 29, 1931. [Class 7 (v).] In an engine starter in which a pinion 12 is moved axially and driven by means of interthreaded springs 15, 16 anchored at their ends in the pinion and in an actuating member 17, the anchorage is obtained by providing the ends of the springs with radially out-turned portions which engage substantially axial slots 20 in the pinion and the member 17, and are cut to form radially extending shoulders 25. As shown, the springs are retained by collars 21, 28 which are forced on annular seats formed by turning down a part of the pinion and the member 17 to the outside diameter of the springs. The collars 21, 28 engage the shoulders 25 on the springs. The member 17 is mounted on the shaft 10 of a starting motor, and a light spring 29 normally holds the pinion 12 out of mesh with the engine gear 11.

Title: Machine for packing articles of any kind
IPC: B65B11/40
Filed: 1926-05-12
Abstract: 252,179. Uhlig, P. May 18, 1925, [Convention date]. Packeting by wrapping-up.-Relates to machines for wrapping caramels or the like and in which the wrapping is carried out in a rotating mould-wheel. According to the invention, the mould wheel is fitted with means, such as a flap or spring, for holding an additional printed sheet for incorporation in the packet so as to be visible through an outer wrapper of their transparent material. As shown, a strip a is fed from a bobbin d, Fig. 1. by an intermittently rotating roller b, into the grip of a tongue, e co-opemating with a side f of the receiving mould. The strip is printed by a stamp k while at rest and at the same time a knife h cuts off a sheet. The sheet is carried round by a rotation of the mould wheel to the securing position, where a plunger p thrusts an article into the mould, carrying with it a waxed or like wrapper drawn from a reel n and cut off by a. knife g. At the moment of insertion, a counter-plunger o raises the side f, and a tongue r prevents the wrapper from disturbing the sheet a, the condition now being as shown in Fig. 2. After two further intermittent rotations, the partially wrapped packet arrives opposite the ejecting point and a spring-mounted roller s folds the outstanding flap of the wrapper over the sheet into the position shown in Fig. 3. An ejector t removes the packet from the wheel to a position in which folders u, v continue the folding. The side f and tongue e coincide with only half of the side of the article when in the mould so that the sheet may be carried out easily with the wrapper. The ends of the wrapper may be twisted. The Specification as open to inspection under Sect. 91 (3) (a) states that roller-shaped objects may be dealt with by the machine.. This subject-matter does not appear in the Specification as accepted.

Abstract: 1,214,203. Semi-conductor devices. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 15 March, 1968 [16 March, 1967], No. 12703/68. Heading H1K. [Also in Division H3] Individual semi-conductor devices of an integrated circuit are formed in islands 11a &c. in an epitaxial layer 11 on a substrate 10 of opposite conductivity type to the layer 11. The islands are mutually insulated by grooves 9 containing polycrystalline semi-conductor material 18. A coating 19 of insulating material may line the grooves 9. In the embodiment shown the grooves 9 are etched through an N type Si epitaxial layer 11 on a P type Si substrate 10 and are filled with silicone oxide 19 and polycrystalline Si 18. An amplifier circuit is formed in the resulting structure, comprising two NPN transistors, each formed by oxide masked diffusion into a separate island, three diodes, each formed by diffusion into a separate island and having an NPN structure, the P zone of each device being shorted to the surrounding N zone as shown in the left-hand island in Fig. 4, and a number of resistors such as R 1 , R 2 , all of which are formed by P type diffusion into a single N type island. Boron and phosphorus are referred to as suitable dopants. A silicon oxide passivating layer 6 is provided, and interconnections between devices are formed by vapour deposited Al tracks 16, 17. In a second embodiment comprising a voltage control circuit three successive Si epitaxial layers (31a), (31b), (34), Fig. 7 (not shown), of N +, N and P types respectively are deposited on a P type Si substrate (30), and grooves (29) are etched, provided with an oxide lining (39) and filled with polycrystalline Si (38). The layer (31a) thus provides a low resistivity buried layer beneath each island, in which transistors, diodes and resistors are formed by diffusion. In this embodiment the P type epitaxial layer (34) is divided into the various isolated regions required to form the individual devices by diffusing N type regions (31c) through the layer (34) to join the underlying N type layer (31b). Ge and GaAs are mentioned as suitable semi-conductor materials, and nitrides may be used instead of oxides as the insulating material.

Class 97(1) The microtome comprises two driving means for providing relative movement at two different speeds between an object to be sectioned and a knife, means being provided for alternately coupling each of the driving means to a rotor for carrying a knife or an object so that the relative speed of the object and knife is higher in the intervals between the cutting actions than it is during them. In the Figure the object 2a is moved past a knife 7 by a rotor 1. The rotor 1 is belt driven from a shaft 10 which may be connected through the electromagnetic clutch 16 to electric motor 18 and which is connected through an overrun clutch to motor 14. This motor 14 has a slower speed than motor 18 and runs idle, when the motor 18 is driving the rotor. As the object 2a approaches the knife 7, a cam 6 on rotor 1 opens a switch 19 and the motor 18 is disconnected so that as the object passes the knife it is driven by the motor 14 only. After the cut has been reformed switch 19 re-opens and rotor 1 is again driven at a higher speed by motor 18. Motor 18 may be permanently connected to the rotor by closing switch 20. Only one motor, connected to clutches 16 and 12 by intermediate gearing need be used.
