Title: Improvements in coin counting machines
Inventor: RAND LEONARD ALEXANDER
IPC: G07D9/04
Filed: 1958-09-16
Abstract: 861,307. Counting-apparatus. INTERNATIONAL COIN COUNTING MACHINE CO. Ltd. Sept. 15, 1959 [Sept. 16, 1958], No. 29676/58. Class 106 (1). [Also in Group XXX] In a machine for counting coins in which coins are fed from a hopper and spread out on a revolving-plate which conveys them to a counter, a feeler overlies the plate and is moved by an excess of coins on the plate to cut off the supply of coins from the hopper. As shown, coins are fed from a hopper 1 to a clockwise revolving plate 2 whence they are conveyed via a guidechannel 4 past a counter 5. A horizontal spindle 7 carries at one end a feeler in the form of a leaf 10 which is raised by a sufficient thickness of coins passing under it, thereby rotating the spindle 7 to move a plate 12 fixed thereto and hence via bolt 15, rotate a cam 13 to open a microswitch 11 cutting off the supply of coins from the hopper 1. The normal position of the leaf 10 may be altered by means of a nut on the bolt 15 which connects the plate 12 and cam 13, thereby altering the critical thickness of coins on the plate 2 which moves the leaf 10. The leaf 10 and cam 13 are returned to normal position by a spring 16.

Title: Improvements in or relating to signalling methods and means therefor
IPC: H03C1/62
Filed: 1929-10-03
Abstract: 346,318. Wireless transmitting systems. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Marconi House, Strand, London.-(Assignees of Roberts, W. van B. ; 155, Hodge Road, Princeton, New Jersey, U.S.A.) Oct. 3, 1929, No. 30062. Convention date, Oct. 4, 1928. Void [Published under Sect. 91 of the Acts]. [Class 40 (v).] In order to prevent heterodyne hisses and similar noises in reception, the average percentage modulation at the transmitting end is maintained approximately constant for both soft and loud signals, and the amount of energy radiated from the aerial is varied in reverse proportion to the strength of the microphone current. A linkage coupling 7, 8, 9 is arranged so as to maintain a constant input voltage, as measured by a voltmeter V, from a low-frequency amplifier 2 to the modulator valve 3. This may be done by adjusting the degree of coupling or the grid bias. Simultaneously the coupling between the oscillator 4 and the radiofrequency amplifier 5 is altered in the reverse sense. The linkage 7, 8, 9 may be controlled by hand, or automatically through a branch circuit shunted across the microphone 1 and comprising an amplifier 10, rectifier 11, and a second amplifier 12. The latter applies a pull varying with the microphone current on a spring-controlled plunger 14 and so rocks the linkage 7, 8, 9 through members 16, 17.

Filed: 1935-11-01
Abstract: 459,061. Key-locks. GIBBONS, F. J. J., St. John's Works, Church Lane, Wolverhampton. Nov. 1, 1935, No. 30199. [Class 44] The invention comprises a method of differing between key-operated locks, and between keys of a number of locks and keys, in that the part circular eye of a keyhole is located at the base of a recess e<1> on the outside of one or more of the locks, and providing only keys for such lock or locks, each with a collar L between the stem and the pin of a key, capable of passing to the recessed eye of the keyhole. This method may be used in conjunction with other methods of differing such as differing the widths of keyhole slots, and the thicknesses of keys therefor. Thus the master key h has a collar L which is small enough to enter the recess e<1> of the lock in Fig. 5, which has a wide tapering key-slot, and also a narrow bit h<1> which may enter another key-hole into which the key g could not be inserted. In this case the kev of the second lock could not be inserted into the keyhole shown in Fig. 5, as the key has a collar which is too large to enter the recess el.

Convention date, Nov. 4, 1931. [Class 17 (i).] Lasting.-Relates to machines of the kind described in Specification 294,640, [Class 17 (i)], wherein a step-by-step gripper lasting machine has a wiper movable toward the shoe in a path inclined toward the plane of the sole and the lasted upper is secured by staples deflected into a curved path as they are driven to anchor them in the shoe. The wiper is mounted so that on contacting with the shoe it is deflected thereby to follow a path substantially parallel with the shoe bottom. This mounting renders the machine suitable for lasting uppers having the whole or a portion of the margin secured by cement, and feed of the staple wire is stopped when desired so that no staples are formed. The wiper moves inwardly over the shoe bottom with the staple inserting device, with its forward edge between the deflector and the shoe, the deflector limiting the yield of the wiper away from its preliminary inclined path. A second upper pressing member is carried by the stapling nozzle to engage the upper inward of the location of the upper fastening staples. The machine is constructed substantially as described in the prior Specification with an edge gauge 10, sole rest 12, and a slide 16 movable at an angle to the bottom face of the shoe carrying overlaying and stapling mechanism, the latter including a nozzle 20 and driver 22 actuated by a lever 38 oscillated by an bell-crank lever 44 urged counter-clockwise by a spring and retracted by a latch 58 pivoted to a lever 54 carried by the guideway for the slide. The wiper 70 underlies the deflector 24 and is pivoted at 73 to a member 72 bolted to the slide, a spring 90 urging the wiper downwardly against a stop forming part of the member 72. The staple nozzle carries a further work presser 102 acting on the upper margin inwards of the end 100 of the wiper.

Title: Process for the production of alkylated hydrocarbons
IPC: C07C2/00
Filed: 1937-11-09
Abstract: Alkylated derivatives of paraffinic, aromatic and naphthenic hydrocarbons are obtained by treating the hydrocarbons with a cycloparaffin, containing less than five carbon atoms in the ring, in the presence of a metal halide and hydrogen halide.  In the examples: (1) cyclopropane and hydrogen chloride are passed into a mixture of methylcyclohexane and aluminium chloride kept at about -10 DEG  C., whereby a propylmethylcyclohexane and a subordinate proportion of dipropylmethylcyclohexanes are obtained; the monopropyl derivative yields aromatic hydrocarbons when dehydrogenated at 250 DEG  C. with the aid of a catalyst comprising platinum on alumina; (2) benzene and cyclopropane are brought to reaction as in example 1; propylbenzene is the main product, but subordinate proportions of dipropylbenzenes, and some hexapropylbenzene, are also obtained; (3) isobutane and cyclopropane are brought to reaction as in example 1; the products are mainly heptanes and decanes.  Reference is made also to the use of cyclobutane as a reagent, to the use of zirconium chloride as a catalyst, and to the treatment of gasolines, gasoline fractions, and cyclohexane.  Normally liquid hydrocarbons are generally treated at below 15 DEG  C., but normally solid hydrocarbons may be treated in the liquefied state at a higher temperature. The process may be effected continuously or as a batch process. Cyclopropane and cyclobutane may be prepared by the action of sodium on a 1 : 3-dihalogenpropane or a 1 : 4-dihalogenbutane, respectively.

Abstract: 718,766. Applying screw-closures to containers. ARNOLD, J. C. (Pneumatic Scale Corporation, Ltd.). Dec. 5, 1952, No. goggi/52. Class 125 (2). Closures 60 are gripped and screwed on to containers by a rotary chuck 50 including an annular resilient closure-gripping element 52 held between a flange 54 and a plate 62 and constricted about the closure by the application of axial pressure brought about by the moving downwards of plate 62 by compressed air supplied through a bore 186. The closures may be screw caps as shown or closures having interrupted threads. A spider 32 rotates continuously about a central pillar 12 and has depending from its periphery a plurality of casings 16 in which chuck housings 14 are raised and lowered by the engagement of rollers 38 with a stationary cam track 42. The housings 14 are rotated continuously about their own axes by the engagement of elongated gears 46 with a stationary gear 48 mounted on the pillar 12. This rotation is transmitted to the chucks 50 through a socket member 104, a friction housing 66, a slipping clutch 68 and the chuck spindle 58. The latter normally rests on a conical face 70 at the bottom of chuck housing 14 but when the chuck engages a container, it is raised relative to the housing 14 against a spring 76 and, if the container is slightly out of alignment, the chuck and the friction housing 66 can pivot slightly about a resilient ring 102 forming the drive between the socket member 104 and the housing 66. When the closure has been applied, clutch 68 slips and by adjustment of its loading spring g6 by screw cap 98, the degree of tightening can be altered. Upper extensions 114 of the rotary parts slide in cylinders 118 carried by spider 32. Compressed air is supplied by a pipe 122 and flows by channels 126, 128 to valves 120 and thence by channels within the rotary parts of the heads to the bore 186 to actuate the chuck. Valves 120 are actuated at the correct times by a stationary cam 194 either to supply compressed air to the chucks or to vent the chucks by way of channels 218, 222, 224. The cams 42, 194 are so set that, in rotation about pillar 12, each chuck descends to embrace a closure, compressed air is supplied to grip the closure, the chuck rises, it then descends to apply the closure to the container, the chuck is vented by valve 120 to release the closure and finally it rises to be ready to start a fresh cycle. U.S.A. Specification 2,082,048 is referred to.
