Title: Coin-freed mechanism for packet carriers of vending machines
IPC: G07F5/04
Filed: 1930-09-05
Abstract: 355,049. Coin-freed article delivery apparatus. HARPER, P. S., 1, Ashurst Walk, Croydon, Surrey. Sept. 5, 1930, No. 26542. [Class 27.] Coin action, with stationary coin forming abutment, and multiple coin.-An article - delivery drawer 1, shown in the Figure, is normally locked by a lever 5, which is pivoted to it and held in position by a spring 6, normally engaging a shoulder 7 on the machine frame 4 during the preliminary movement of the drawer. A coin or coins 9 inserted in a shoot 8 pass a pivoted stop 10 to rest on the outer end of the lever 5, a projection 11 of the stop engaging over the coin or the last coin to prevent them from being raised in the shoot, when the drawer is pulled. The drawer is connected to the frame 4 by pivoted links 2; 3, so that it follows an arcuate path, when pulled. This causes the lever 5 to be rocked and miss the shoulder 7 since the coins form a solid abutment between its outer end and the projection 11. The coins fall from the lever before a packet can be taken from the drawer. The same release mechanism can be used for a recessed delivery roller. In a modification, the drawer slides in a straight path in the machine frame and the locking lever 5 is provided with an inclined end to engage the bottom coin as the drawer is pulkd.

Title: Improvements in or relating to the determination of the number of fibres of approximately the same length in a cotton sample
IPC: G01N21/55
Filed: 1955-09-20
Abstract: 817,833. Photo-electric inspection. LICENCIA TALALMANYOKAT ERTEKESITO VALLALAT. Sept. 20, 1955 [Sept. 24, 1954], No. 26796/55. Class 40 (3). [Also in Group IX] In order to determine the staple-lengths present in a sample of cotton fibre it is fed to an intermittently operated stationary staple laying device 8, of specified type having suitable drive mechanism. The laying device places the fibres on a uniformly moving dark plush band 1 in such a way that they are in a series of groups of fibres, each group consisting of fibres of the same length and containing fibres longer than those in the preceding group. As the band 1 moves round, driven by motor 5, the groups of yarns pass through a beam of light from lamp 7. The more fibres there are in a group the greater the intensity of the light reflected and consequently the higher the electrical output from observing photo-electric cell 9. The output from cell 9 is amplified at 11 and fed to a recording device 10 which produces a diagram showing the numbers of fibres in the different length groups. When there are no further fibres on the band ], the amplifier output drops to zero and a relay is de-energized and breaks the circuit of lamp 7.

Title: Improvements in and relating to waveguide devices
Inventor: HARVEY ARTHUR FRANK
IPC: G01R23/04
Filed: 1948-10-15
Abstract: 649,067. Wave meters. MINISTER OF SUPPLY. Oct. 15, 1948, No. 26883. [Class 37] [Also in Group XL (b)] A detecting device is connected to one T-arm of a hybrid T-junction fed with ultra shortwave energy through the other T arm, one of the in-line arms is closed by an adjustable short-circuiting piston and the other in-line arm is coupled to or continued as a wave-guide or other transmission path, long compared with the operating wavelength and having an unmatched termination. The arrangement may be used as a wave-meter by feeding the wave to be measured into the shunt T-arm 4 and adjusting the position of the short-circuiting piston 5 in the in-line arm 1 so that an indicator connected to the detector coupled to the series T-arm 3 shows zero power in this arm. In-line arm 2 is connected to a waveguide 6 of the order of a hundred wave lengths long with an unmatched termination. Energy fed in shunt arm 4 enters arms 1, 2 in phase and, by adjusting piston 5, the reflected energy may be made to arrive at the junction in phase, giving zero power in series arm 3. The long path in guide 6 increases the adjustment of piston 5 necessary to give a zero reading, and the piston adjusting means may be calibrated in frequency. The long guide 6 may be coiled or folded or may be replaced by a coaxial line or free space path.

Abstract: 444,592. Oscillating motors. GOLDSCHMIDT, R., 15a, Clarendon Court, Maida Vale, London. Sept. 22, 1934, No. 27286. [Class 35] A motor for setting the blade of a safety razor in vibration comprises a body portion 5 caused to vibrate by an armature 1 mounted thereon, the body being coupled with the blade 23 and so mounted upon a handle 10 that the motor as a whole is capable of vibrating relatively to the handle. The motor is similar to that described in Specification 442,871, the armature axis passing through the centre of gravity. The body 5 acts as a casing for the armature and the pivot axis 9 passes through the centre of gravity of the body and armature together with the attached razor. The armature polepiece 4 is arranged to strike the casing 5 either directly or through a stiff spring or buffer. The polepiece 3 may be provided with a stiff spring, and the polepiece 4 with a light spring at one side and a hammer head at the other. The handle contains a battery 11 and the end cap 14 may act as a switch. A rubber or other sealing ring 15 between the body 5 and the handle 10 prevents the entry of moisture &c. and serves to centre the body. A further rubber ring 16 or resilient pads may also be provided to act as a buffer and may or may not fill the space between the body and the handle. The body may be arranged to receive a razor of standard form and an unbalanced rotary armature may replace the vibratory armature 1. It is explained in the Specification that components of vibration should be imparted parallel with the edge of the blade and also at an angle to the edge. This may be effected by rotating the razor slightly about the axis of the threaded supporting member 19. Locating means may be provided to define the correct position of the razor.

Abstract: Hexamethylene 1,6-diamine is produced by contacting liquid adiponitrile with hydrogen and ammonia at a pressure greater than 150 atmospheres and a temperature of from 60 DEG  to 135 DEG  C. in an elongated reaction zone or containing a solid hydrogenation catalyst, the amount of hydrogen in the reaction zone being at least the number of moles of adiponitrile multiplied by the diameter of the reaction zone in millimetres and divided by 0.4, the adiponitrile being fed to the reaction zone at a rate in kilograms per hour of not more than the length of the reaction zone expressed in metres divided by 18 and the hydrogen being introduced as a mixture containing from 5 to 20 volumes per cent ammonia as measured in the gas phase.  The preferred catalyst comprises from 20 to 27% cobalt, from 5 to 10% manganese and from 0.05 to 1% silver on a solid support, the catalytic metals being in the metallic state.  Hexamethyleneimine, 1,2 - diaminocyclohexane and 6,61-diaminohexylamine are obtained as by-products.ALSO:A catalyst for the hydrogenation of adiponitrile to hexamethylene-1, 6-diamine in the presence of ammonia and hydrogen comprises 20 to 27% cobalt, 5 to 10% manganese and 0.05 to 1% silver on a solid preferably particulate support, the promoting metals being generally in the metallic state.  Suitable supports include pumice stone and other essentially siliceous solids, preferably of a particle size range of about 1 to 10 mms. and the catalysts generally will contain about 30% by weight of promoting metals.  The catalyst may be made by dissolving in water the nitrates or other heat decomposible water-soluble salts of the promoting metals, impregnating the support material with this solution, heating the resulting mass to about 130 DEG C to dry it and then to about 300 DEG  to 400 DEG C to decompose the salts.  The promoting metals are reduced to the metallic state by a stream of hydrogen at 350 DEG C, then treated with CO2 to remove entrained hydrogen and with an inert gas to avoid pyrophenic qualities in the catalyst. In the Example the catalyst comprises 23% cobalt, 7% manganese and 0.38 silver supported on pumice stone having a size range of 4 to 6 mm.
