Title: An improved coin freed apparatus for cleaning tobacco pipes
IPC: G07F17/00
Filed: 1919-07-04
Abstract: 152,103. Genzell, F. July 4, 1919. Hiring pipe-cleaners.-A coin-freed apparatus for cleaning tobacco pipes and cigarette holders comprises a rotary bowl-scraper and a suctionproducing arrangement which is set during the operation of the scraper and released manually at the conclusion of the scraping. The casing containing the operating mechanism carries a slidable cylindrical member 2 controlled by a spring 9 and terminating in a cup 3 against which the bowl of a pipe is pressed. Pressure on the pipebowl causes the depression of the cylinder and allows two scraper blades 5 to emerge and be pressed by a spring 6 against the bowl. The scrapers are carried by a shaft 9 rotated by a gear 13, 14, shaft 15, and hand-operated crank 16. The shaft 15 is locked by a coin-freed bolt 17. The shaft 9 drives, through a clutch 35, 36, a worm 34 gearing with a wheel 37, on the shaft of which is loosely mounted a pulley 39 normally clutched to the shaft by a dog 40 withdrawable by a pull rod 41 co-axial with the shaft. A cord 42 is secured to the pulley and to a bar 43 forming part of a piston 48. The piston is surrounded by a spring 46 and is drawn upwards against the pressure of the spring by the cord 42, when the crank 16 is turned, until the member 43 engages the lower end of the shaft 9 and separates the clutch members 35, 36. On the conclusion of the scraping operation, the rod 41 is operated, and the piston on its return stroke draws air through the pipe by way of a tube 50 secured in a diaphragm 30. The piston has attached thereto a protective sleeve of canvas 44 and a cup 49 for receiving waste material. A hinged plate 55 locked by a bolt 56 and padlock 58 closes the casing and the coin outlet 59. The bolt 17 is connected by a pin-and-slot to a sleeve 19 between which and the frame part 11 is a spring 20 acting to withdraw the bolt, but prevented by the engagement of the end of the sleeve with an abutment 23 formed on a stub-shaft 21 co-axial with the sleeve. A counterweighted lever 22 is engaged by the coin to turn the shaft 21 and remove the abutment from engagement so that the sleeve and bolt may move away from the locking position. A cam 26 is pivoted to the sleeve and connected by a link 27 to a flexible diaphragm 29 in the top of the cylinder. When the diaphragm is sucked in by the stroke of the piston, the cam is moved to impel the sleeve away from the abutment 23 and allow the bolt to be moved into locking position by a spring 26a interposed between it and the shaft 21.

Title: Improvements in and relating to braking means for spinning & twisting machines
IPC: D01H1/20
Filed: 1929-05-31
Abstract: 312,926. International General Electric Co., Inc., (Assignees of Allgemeine Elektricitõts-Ges.). June 1, 1928, [Convention date]. Brake arrangements.-The brake of the tin roller shaft of spinning-machines is controlled by an e I e c t r omagnet M which is switched on and off by means of the switch of the driving - motor. In the arrangement shown in Fig. 1, the electromagnet is connected with the stator terminals U, V, W of the driving-motor so that it operates to raise the brake lever B against the effect of the weight G when the motor is started and remains energized while the machine is running. The electromagnet may be arranged to apply the brake against the retractive effect of the weight, and is then not energized during the normal running of the machine; in this arrangement the control switch has three positions, in which the driving- motor only is switched on, the driving-motor and the electromagnet are switched on, and the electromagnet only is switched on respectively, and the switch is so arranged that, on release, it is retracted by a spring to the " off " position to prevent the electromagnet being inadvertently left switched on.

Title: Method of procuing a metal part having at least one magnetic  portion and at least one non-magnetic portion
IPC: C21D6/00

Abstract: 1434214 Heat-treating magnetic alloys TSENTRAL NI INST CHERNOI METALLURGII IM IP BARDINA 9 April 1973 16966/73 Headings C7A and C7N  An integral metal component one portion of which is magnetic and one portion non-magnetic is produced from an alloy which develops magnetic properties on ageing but loses them on high temperature tempering by heating that portion which is to be magnetic to 450-980‹C and soaking until magnetic properties are developed, followed by cooling. The non-magnetic portion is then heated to a temperature between 1000‹C and the melting point, and cooled at a rate sufficient to prevent development of magnetic properties. It may be advantageous to initially treat the whole workpiece to make it magnetic, followed by local treatment of those portions to be made non- magnetic. In a preferred embodiment those portions to be finally magnetic are initially heated t 1050-1350‹C and soaked to eliminate the effect of any previously applied treatments, followed by cooling and subsequent heating to develop magnetic properties. Cooling after the latter step may be a magnetic field. A preferred alloy contains, in percentage by wt-

Title: Improvements in or relating to the manufacture of light-sensitive photographic material
IPC: G03B21/32
Filed: 1940-11-27
Abstract: 545,469. Automatic control systems. HARRISON, G. B., HERCOCK, R. J., and HORNER, R. G. Nov. 27, 1940, No. 16986. [Class 38 (iv)] [Also in Group XL] A photographic material, for example a film, is scanned by a light beam and the reflected or transmitted light is directed on a photo-electric cell the output of which serves to indicate or record any irregularity in the photographic coating and to perform any desired operation in dependence thereon. A light beam is used to which the photographic material is insensitive. In the apparatus shown in Fig. 1, light from a lamp 1 is directed by an optical system 2, 4 with an aperture 3 through an infra-red filter 5 to a prism 6 which reflects the light to an inclined mirror 8 on the rotating shaft of a motor 9. The light reflected by the mirror 8 during its rotation traces a cone around the prism and scans a film 10 in a series of arcs while the film is gradually moved through the apparatus. The light passing through the film falls on a cell 11. In a modification, Fig. 2, the light from a lamp 1 is directed by a telescopic collinator 12 to an oscillating mirror 13 which reflects the light through a filter 5 and the film 10 to the cell 22, the oscillations of the mirror scanning the film in a series of transverse lines. There may be a tendency for the film to wander from side to side causing the scanning spot to go beyond the edges. Means may be provided for automatically centring the scanning action. For this purpose, the optical system is arranged to produce an additional wide scanning spot or two additional scanning spots so positioned that an additional scanning spot reaches the edge of the film just before the main scanning spot. An additional cell or a pair of cells is also provided to be affected by the additional scanning spot or spots when the edge of the film is overshot. This cell or pair of cells controls a direct-current through the coil 20 to make the centre of the oscillation of the mirror follow the central line of the film.

Title: An arc welder
IPC: B23K9/22
Filed: 1963-04-30
Abstract: 1,015,693. Welding by fusion. PULSE ARC WELDER CO. April 30, 1963 [May 7, 1962; Feb. 25, 1963], No. 17006/63. Heading B3R. [Also in Division H2] A stored energy discharge welding circuit comprises banks of capacitors 63-70, charged through a rectifier 32, resistor 34 and contacts 38, 41 discharging into two circuits. One 96- 98 forms a resonant circuit of high-frequency, say 1000 Me., which initiates a discharge across the electrodes 14, 16, and the second reduces the impulse through an autotransformer 90 to a value high enough to maintain the arc, but not to strike it. In the event of an arc not being struck the capacitors are discharged through the autotransformer winding 90 to earth. Should the operator touch the electrodes 14, 16, the resonant circuit 96, 98 is thrown out of resonance thus reducing the H.F. voltage. The transformer 78 core which may be of ferrite saturates at a value which prevents the energy discharging through the second circuit from being transformed back into the first circuit. A small capacitor 104 of low inductance is paralleled with the main capacitors 63-70. The H.F. pulse is diverted from the rest of the circuit by a low current rapid switching diode 110 in parallel with a high current diode 112. Either or both of the electrodes 14, 16 may be a workpiece, e.g. a wire or a bundle of wires.
