Title: Improved machine for beating and cleaning sheep-skins and like skins
IPC: D06G1/00
Filed: 1923-03-23
Abstract: 215,516. Wallace, T. W. March 23, 1923. Furs and the like, beating mechanically. - Sheep skins &c., laid on an endless conveyer 6, are carried between feed rolls 8, 9 which support them suspended between a stationary beating surface 10 and a similar surface 11 oscillated about an axis 15 by a crank-shaft 21. The surfaces consist of semi-octagonal bars mounted on frames which, in the case of the stationary surface, are resiliently supported by means of plungers 12 working in spring casings 13. The beaters 11 are attached to arms 14 rocked bv the shaft 21 through a connecting rod 18 and yielding connections 17. To institute a cycle of operations, a pedal 24 is depressed to connect a pulley 33 (driven by an open belt from shaft 21) to its shaft 32 which thereupon, through spur gearing, rotates the lower roll 8 to feed the skin into position. When the roll has rotated to the extent of 1“ revolutions a pin 43 fixed to its spindle has turned a loose collar 42 sufficiently to bring a projection thereon against a lever 45 so that this is displaced and through a bell-crank 47 returns the driving clutch on shaft 32 to inoperative position. When the skin has been beaten to the desired degree the pedal is again operated but in the opposite direction to throw the clutch into engagement with a pulley 34 driven from shaft 21 by a crossed belt. The feed roll 8 is consequently rotated in the reverse direction to withdraw the skin and return it to the conveyer. At the end of 1“ revolutions of the roll 8 the pin 43 and collar 42 again act to shift the lever 45 and restore the clutch once more to normal position. Arrangements could be made whereby the beaters are oscillated only during the interval between the feeding and withdrawing motions of the rolls 8, 9.

Title: Direction signalling systems
IPC: B60Q1/38
Filed: 1956-03-20
Abstract: 825,752. Road-traffic signals on vehicles. HOLLINS, J. R. March 20, 1956, No. 8678/56. Class 118 (2). [Also in Group XXXVII] A direction signalling system for vehicles comprises a selector switch with means to latch the switch in either operated position and electrically energized release means effective after a predetermined period of energization to release said latch means, with an energizing circuit for said release means completed only when said selector switch is in operated position and having potential applied when a driveroperated control element is in the vehicle motion permitting position. A selector switch 10 comprises a dielectric base 11 carrying pins 13 engaging slots 21 in a sliding member 20. An operating lever 15, pivoted at 12 on the base 11, serves to move the slide 20 in the selected direction against the action of centring springs 14 which co-operate with abutments 23. In the operated position a contact strip 53 on the slide 20 bridges contacts 51 and 52R or 52L on the base 11 to connect the flasher 50 to right-hand or left-hand front and rear signalling lamps RF, RR or LF, LR respectively. A pilot lamp PL flashes when the signalling lamps are thus in circuit. A bimetallic strip 30, shaped as shown, normally rests on a dielectric strip 28, but when the slide 20 is moved to an operated position it is retained there by the strip 30 engaging one of the notches 26. At the same time the battery is connected via the conductive strip 25 and bimetallic strip 30 to a heating winding 35 whose circuit is completed by switch 45 when the accelerator pedal 47 is depressed. After a predetermined heating period the bimetallic strip 30 bows outwards to allow slide 20 to restore to its neutral position under action of a spring 14, thereby cancelling the direction signal. Should the vehicle be delayed in making a turn (e.g. by heavy traffic) the accelerator pedal would not be depressed during the waiting period and hence the signal would not be prematurely cancelled. Instead of using the accelerator pedal, the brake or clutch control may be used (Fig. 3, not shown) but in this case the associated switch would be normally closed, and open while the pedal was depressed. In an alternative embodiment (Fig.. 2, not shown) the member 20 is pivoted to rotate instead of sliding, and the operating lever 15 is rigidly attached to it.

Abstract: 107,411. Constantinesco, G., and Haddon, W. June 26, 1916. Spray carburettors; vaporizers, external.-In engines which can be run alternatively on different fuels such as petrol and heavy oil and in which the supply of the different fuels is controlled through electro-magnetic devices by a thermostat, the electro-magnets are so arranged that, when both are energized, one fuel is cut off and the other admitted to the engine. The outlet of the petrol carburettor a is controlled by two valve spindles l, m, the former of which is raised by the suction of the engine and the latter actuated by an electro-magnet k. The valve spindle h of the paraffin float chamber e also is actuated by an electro-magnet f, and the circuits are arranged so that the magnets are energized only when a light lift valve q is open. This valve has a disk r which nearly closes an air inlet and its spindle rests on a contact s when the valve is closed. A mercury thermostat p having two contacts in its stem is placed in the circuits of the electro-magnets. At starting, petrol is supplied owing to the raising of the valve spindle l, but as the speed increases the suction becomes sufficient to raise the valve q and air is drawn through the exhaustheated vaporizer g. The upward movement of the valve q also closes the contact s. When a certain temperature is attained, the mercury in the thermostat reaches the contact u and the circuit of the electro-magnet f is completed. Paraffin now enters the vaporizer, and the engine runs on a mixture of paraffin and petrol until the temperature is sufficiently high for the mercury to reach the contact v, when the magnet k is energized and the supply of petrol cut off. The carburettor a mav be of the kind described in Specification 17176/14.

Abstract: 269,166. I. G. Farbenindustrie Akt.- Ges. April 10, 1926, [Convention date]. Catalytic agents, preparation of; catalytic apparatus.-The invention is an improvement on the process of Specification 261,559 in which hydrocyanic acid is produced from formamide or ammonium formate or both by heating rapidly to above 350‹ C., preferably 400-900‹ C., and rapidly cooling the reaction mixture. According to the invention, the vapours of formamide or formamide containing ammonium formate are passed in a highly diluted condition at high velocity over metals in the absence of the catalysts mentioned in Specifications 261,559, 233,080 and 220,771. Iron, manganese, nickel, aluminium, and copper and their alloys are mentioned as suitable. They may be used in the form of granules, turnings or wire netting with or without carrriers or in conjunction with other substances which are not dehydrating catalysts. The catalyst may be in the form of a reaction tube of or lined with the metal chosen. When mild steel or Krupp's V2A steel is used, 350-450‹ C. is suitable; nickel is used at 450-500‹ C., and aluminium at 500-600‹ C. The vapours may be diluted with ammonia, or inert gases containing ammonia, or inert gases alone, and the high velocity is obtained by using reduced pressure. In the examples, formamide vapour, which may contain ammonium formate and formic acid, is passed through an iron, nickel, or aluminium coil at reduced or ordinary pressure; formamide vapour is passed through a V2A steel tube, which may be two-thirds filled with iron turnings; or a quartz tube may be used containing aluminium shreds or turnings or granules of manganese or other metals, or alloys such as ferrosilicon, with or without carriers or in conjunction with other compounds may be used.

Abstract: 883,987. Packaging machines. TREDGET, C. A., and MOLINS MACHINE CO. Ltd. March 16, 1960 [March 17, 1959], No. 9218/59. Class 94(1). An apparatus in which articles are packed in a first machine and are then transferred to a second machine wherein an outer wrapping is applied, comprises conveyer 16 between the machines, and a detector finger 24 contacting the packages on the conveyer 16 and movable, if a gap occurs in the normal succession of packages, to cause a switch 26 to open and break a circuit to a normally closed magnetic clutch 30 that couples the wrapping machine to the packing machine, so that the absence of a package from the conveyer 16 causes the wrapping machine to stop. As shown, cigarettes in a hopper 3 pass through outlets 4 to two parallel channels 6 wherein pusher members carry the cigarettes through wrapping means 7 enclosing the cigarettes in metal foil. A second conveyer 8 has pockets that receive slides S and each slide receives a foil wrapped package from each of the channels 6. A transverse conveyer 10 moves the filled slides in to shells 11 and the resulting packages are then carried along a bed 12, past a revenue stamping device 13, to an intermittently driven wheel 14 having radial pockets that receive the packages and carry them round to the conveyer 16 on to which they are ejected by a pusher 15. At the end of the conveyer 16, a pusher 17 moves each package to the wrapping machine 22 in which they pass through various devices 23 which feed and fold a wrapper around each package. The wrapped packages may be finally turned up on edge. The wrapping machine can be driven independently by a motor 31 if it is desired that the wrapping machine shall function even though the clutch 30 is open.
