Title: Improvements in coin-freed apparatus
Filed: 1933-05-31
Abstract: 407,570. Coin-freed apparatus. KERR, R., 459, Smithdown Road, Wavertree, Liverpool. May 31, 1933, No. 15675. [Class 27.] Testing coins.-A coin 1 inserted through a slot 2 is turned to an horizontal position before entering a shoot 6 by an oblique member 4, the coin then sliding down the shoot till it is arrested by a stop 7 over a slot 8 in the shoot. A plunger 10 is depressed by a lever 11, the plunger having a resilient foot 21 which engages the coin and, if the latter is a soft metal disc, pushes it through the slot 8 to a return shoot 23. Genuine coins are not bent and, when the stop 7 is raised by the return of the plunger 10, slide down the shoot and pass over a partition 30. This partition is disposed to one side of the central line of the shoot so that a genuine coin tends to fall to one side of the partition and pass to the coin-freed mechanism by a shoot 33. A magnet 31 on the other side of the partition attracts iron or nickel discs, which have passed the rigidity test, so that they fall to a receptacle for such bad coins. The stop 7 is raised by a hooked spring 27 on the plunger engaging under a flange 26 on the stop which slides on rods 24. When the plunger is partly raised, a yoke 25 on the rods 24 releases the spring so that the stop 7 can drop to its coin-arresting position. A second coin is prevented from passing down the shoot 6 while the stop 7 is raised by two depending rods 29 carried by the plunger.

Title: Improvements relating to indicating and recording instruments
IPC: G01D5/04
Filed: 1940-10-31
Abstract: 543,271. Indicating apparatus. RECORD ELECTRICAL CO., Ltd., and WOODCOCK, R. Oct. 31, 1940, No. 15949. [Class 106 (iv)] In indicating and recording instruments such as speedometers, ammeters and voltmeters, the pointers or dials are actuated relative to one another without employing gear wheels, by transmitting the torque of the instrument to a torsion spring or springs various points of which are connected to the respective pointers or dials. As shown in connection with an instrument having two pointers b, j with relative ten to one movements, a spindle a which is turned by the force to be measured is attached to the centre coil of a spiral spring d, and carries the pointer b. The outer coil of the spring is coupled by a strip e to the outer coil of spiral spring f anchored by its inner coil to a fixed bracket g. An arm h on the strip e carries the pointer j. The spring f has nine times the torsional strength of the spring d so that the pointer j receives one tenth of the displacement of the pointer b. In a modification applied to a speedometer, the outer coil of the spring d is connected to the inner coil of the spring f, the outer coil of the spring f being fixed.

Title: A process for the production of n-p-n or p-n-p-junctions in semiconductors
IPC: H01L21/00
Filed: 1957-05-20
Abstract: 854,757. Semi-conductor devices. INTERMETALL GESELLSCHAFT FUR METALLURGIE UND ELEKTRONIK. May 20, 1957 [May 19, 1956], No. 15958/57. Class 37 A method of making a PNP or NPN junction body comprises causing the activator impurities to differentially diffuse out of a semi-conductor body containing unbalanced amountsof donor and acceptor impurities having differing diffusion constants. In this process the surface concentration of the activator impurities may be controlled either jointly by carrying out the process under a controlled pressure of inert gas or independently by varying the vapour pressure of the impurities in the atmosphere in which the process is carried out or by chemical means, e.g. by using an oxidising atmosphere if the oxide of the impurity has a high vapour pressure. An NPN junction body suitable for use in a transistor is made by heating a crystal of N type germanium doped with antimony and indium in an atmosphere containing antimony vapour at a high partial pressure. As a result the diffusion rate of the indium exceeds that of antimony but on account of the low diffusion constant of indium its concentration gradient is steeper giving rise to a final impurity distribution as shown in Fig. 2 with a pair of PN junctions spaced approximately a micron apart. Since the junction nearer the surface is more abrupt than the other and the net impurity gradient in the middle zone is so directed as to cause holes to be accelerated from the abrupt to the shallow junction the device would be operated with the surface zone connected as emitter. A similar NPN or PNP junction body could alternatively be obtained by heating in vacuum a body in which the predominating impurity has a higher diffusion constant and lower vapour pressure than the other.

Abstract: 1365872 Sewing machines COURTAULDS Ltd 27 Sept 1971 [28 Sept 1970 21 May 1971] 45990/70 and 16215/71 Heading D1G A pair of pneumatic sensors in a pneumatic control circuit are mounted on the cloth plate C of a sewing machine in such a way that when a workpiece is placed on the plate air streams are obstructed causing the control system to connect the treadle linkage and lower the presser foot. When the workpiece is removed the treadle linkage is disconnected, the brake applied, the presser foot raised, and the thread cutter operated. Compressed air is supplied to two first jets 3, 6 mounted respectively before and after the needle, and above the cloth plate. These jets blow air through apertures 9a, 9b to deflect air from jets 4, 7 which would otherwise enter outlets 5, 8 respectively. When a workpiece interrupts the first air jet 3 air from the second jet 4 pressurises the pipes 20a and 21 to switch the diaphram operated valve 18. This in turn switches valves 26 and 27 to pressurise the reservoir 30 and operate pistons 36 and 39 which operate the treadle linkage and presser foot. The presser foot may be lifted temporarily by operating a valve 37 by a knee switch 38. When the work piece is removed the valve 18 switches back, causing valves 26 and 27 to disconnect the treadle linkage and lift the presser foot, as well as venting the reservoir into a valve 22 to momentarily operate the thread cutter piston 25. Air from the button operated valve 17 may be blown through the outlets 5, 8 to clean them, or the first jets 3, 6 may be positioned below the cloth and the blocks 1a, 1b above it. The air pressure in the embodiment is 4.2 kg/cm<SP>2</SP>. The sensitivity of the second sensor 1b may be reduced by narrowing a section of the pipe 20b.
