Title: Improved clothes washing machine
IPC: D06F13/04
Filed: 1945-02-24
Abstract: 595,769. Washing-machines. CONSTANTINE, W. W. (General Motors Corporation). Feb. 24, 1945, No. 4676. [Class 138 (ii)] A'clothes washing-machine comprises a tube 10 containing a vertically reciprocable agitator 13 having a lower flared coaxial conical portion which remains below water level and is in close proximity to the base of the tube at its lower limit of movement, the nature of the reciprocation being such that the rate of change of speed at the lower limit is less than that of a simple harmonic reciprocation at the same frequency. By this movement, the bulk of the clothes is caused to float in the upper part of the liquid. As shown in Fig. 1, the agitator is fixed to the upper end of a rod 16 which is fixed at its lower end to a plunger 21 slidable in a fixed bearing 17. A spring 19 urges the plunger downwardly so that a roller 23 thereon is maintained in contact with a cam 15 which is rotated at a uniform speed by a shaft 24, the cam being shaped to give the required rate of change of speed of the agitator at its lower limit of reciprocation. The machine is supported on legs 25 and a cylindrical apron 26 through a rubber ring 28, and a cross-member 27 supports a ring 29, secured in a central opening 30 in the bottom of the tub and fixed to the lower end of a sealing bellows 31 which is attached at its upper end to the agitator. In another construction, Fig. 4, a rotatable shaft 24 drives a cam 51, connecting rod 52, plunger 53 and supporting rod 54, springs 56, 57 extending between a disc 55 fixed to the rod 54 and upper and lower rings 58, 59 on the agitator. The rod slides relatively to the rings and, when the shaft is rotated at a uniform speed, the spring device causes the agitator to lag behind so that it has a lesser rate of change of speed near the lower limit of its reciprocation than in simple harmonic motion and a higher rate near its upper limit. In a modification of this construction, Fig. 6 (not shown), the spring device is arranged inside the plunger 53.

Title: Colour electrophotographic method
IPC: G03G13/01
Filed: 1974-02-01
Abstract: 1423793 Multi-colour electrophotography HITACHI Ltd 1 Feb 1974 [5 Feb 1973]  04734/74 Heading G2H In a process in which a photo-conductive sheet 12 is charged, exposed to a light image through a first colour filter 68, and developed to produce an image in a first complementary colour which is then fixed, and the process is repeated a number of times corresponding to the number of colour separations desired, in the charging step in each image-forming process the sheet 12 is charged to a potential close to its saturation value. The potential required to produce saturation increases for the second and subsequent image-forming processes, and is obtained by having a stepwise adjustable high voltage DC supply 100 connected to the electrode 32 of a corona discharge device 30, as shown, or may be obtained by adjustment of the value of a leak resistance connected to a control grid of a corona device, by adjustment of the speed of rotation of the drum 10 carrying the sheet 12 to vary its time of exposure to the corona, or by adjustment of the distance between the corona device 30 and the sheet 12. The developing device 40 includes a reservoir 41-44 and an applicator roller 45-48 respectively for each colour and is movable to bring the appropriate colour into position as required. A roller 70 with a cleaning pad 72 both removes developer carrier liquid from the sheet 12 and fixes the developed images.

Title: Coin-controlled mechanism
Inventor: MAYOR ROBERT
IPC: G07F17/14
Filed: 1956-02-15
Abstract: 795,319. Coin-freed turnstiles. ELLISON & CO., Ltd., W. T. Feb. 15, 1957 [Feb. 15, 1956], No. 4753/56. Class 27 A coin-freed mechanism for releasing turnstiles and other devices comprises a bolt 4 which, upon being moved manually towards a plunger 5, actuates the latter through a mechanical connection provided by an inserted coin and so releases the turnstile or other device, the coin in this effective position being supported on two pins 13 spaced apart horizontally by a distance just sufficient to prevent a coin of the correct denomination from falling between them. The bolt 4 is slidably mounted in a guide 1a and is urged into contact with a pawl 8, rigidly connected to an operating handle 2. by a spring 15. The plunger 5, which is also slidably mounted in a guide 1b and urged towards the bolt by a spring 11, is provided in its operative end with two clearance holes 5b co-operating with the pins 13 which are carried on an L-plate 6 screwed to a guide 1a. A coin-shoot 3 of size corresponding to the spacing of the pins 13 is mounted above the guides 1a, 1b. When a coin of correct value is inserted, it is supported on the pins and movement of the bolt 4 is transmitted to the plunger 5 so that a peg 12 thereon effects the release of the turnstile; continued movement of the turnstile, together with the plunger, after the bolt has reached the limit of its .normal travel, releases the coin so that it falls into a collecting box. If the mechanism is operated without the insertion of .a coin, the bolt 4 moves through a clearance slot 6a in the plate 6 and into a hole 5a in the plunger without effecting movement of the plunger. A guide plate 7 is provided to prevent coins, inserted during movement of the bolt, from jamming the mechanism. In order that the mechanism may be used with different value coins, the coin shoot 3 and the bracket 6 with the pins 13 are made interchangeable or adjustable, and, the guide plate 7 is made interchangeable.

Patent GB-687229-A (GB)
Title: Improvements in or relating to the purification of dehydroacetic acid by distillation
Inventor: WIGGINS GLENN CHARLES
Filed: 1951-03-01
Abstract: Dehydroacetic acid (C8H8O4) is purified by distilling it under reduced pressure in the range 1-15 mm. absolute in the presence of 1 to 5 parts by weight of a glycol or a glycol mono-alkyl ether having a boiling point between 235 DEG  and 280 DEG C at atmospheric pressure.  The dehydrocacetic acid distils over with the glycol or glycolether, leaving most of the impurities in the still.  The distillate is cooled until the purified dehydroacetic acid crystallizes out.  The crystals are then separated from the mother-liquor by centrifuging, filtering or decanting.  Suitable glycols and glycolethers are: Diethylene glycol, triethylene glycol, tripropylene glycol, the monomethyl and monoethyl ethers of triethylene glycol, and the lower monoalkl ethers of tripropylene glycol.  In an example, commercial dehydroacetic acid (141 grm.) containing about 20 per cent impurities was mixed with tripropylene glycol monomethyl ether (432 grm.) and the mixture was distilled at 118 DEG C under an absolute pressure of 5-7 mm. until 530 grm. of distillate had collected.  The distillate was warmed to 85 DEG C and then cooled to 15 DEG C, whereupon dehydroacetic acid crystallized out.  The crystals were filtered off, washed with water to remove traces of glycol-ether, and dried for 5 hours at 50-60 DEG C.  White crystals with a melting-point of 109 DEG -110.5 DEG C were obtained (yield 92 per cent).  Specifications 657,797, 661,472, 661,473 and 664,845, [all in Group VI], are referred to.

Title: Improvements in or relating to thermionic amplifiers and circuit arrangements therefor
IPC: H04N5/44
Filed: 1927-02-23
Abstract: 291,143. Round, H. J. Feb. 23, 1927. Thermionic amplifiers and detectors. - An inductive reactance or choke is inserted between the plate of one valve and the grid of a following valve, in series with the coupling condenser of the resistance-capacity coupling; the object being to keep up the amplification of the higher voice frequencies. Fig. 1 shows a valve 1 coupled to a following valve by the usual plate resistance 5, coupling condenser 7, and grid leak 11. The choke 8 is inserted on one or other side of the condenser 7; and a condenser 13 (which may be shunted by a damping-resistance. 14) is connected across the grid and filament. At the resonance frequency of the choke in combination with the grid-filament capacity, amplification is increased, whilst beyond that frequency there is a comparatively sharp cut off, which may be adjusted to about five or six thousand cycles. The choke also tends to prevent radio frequency currents from passing from a detector into an audio-frequency amplifier. A condenser 15 may be employed to by-pass radio frequency currents between the plate and filament of the valve 1; and the provision of the choke counteracts the tendency for this condenser to reduce amplification of the higher voice frequencies.
