Title: Improvements relating to polish distributing and like apparatus
Inventor: COLLINS JOHN HENRY
IPC: B24B57/04
Filed: 1950-07-11
Abstract: 692,869. Grinding and polishing. DAMIEN (LONDON), Ltd., M. July 11, 1951 [July 11, 1950], No. 17345/50. Class 60. An apparatus for distributing grinding, polishing or the like paste 3 in cake form to a grinding &c. disc 1 applies the cake to the disc intermittently by combined reciprocating and forward feed motions. The cake 3 is supported in a housing 4 carried by a frame 30 having bearings 16 for shafts 15 mounted in bearings 17 on a slide 18 that is adjustable on a carriage 19. The frame 30 is advanced along the shafts 15 to apply the cake 3 to the disc 1 of a polishing machine, such as described in Specification 692,870, by a cable H operated as the workpiece 32 is brought into operative relationship with the disc. The cable H is connected to a lever 13 pivoted at 38 to the frame 30. As the lever is rocked by the cable H against the influence of a spring 14, it causes rotation of a lever 10 connected to the lever 13 by spring-link 39, 42, 44. Further rocking of the lever 13, after it has contacted an edge 13'of the frame 30, causes the frame to be advanced against the action of a spring 25 acting between one of the bearings 16 and a part 26 on the end of one of the shafts 15. During the application of the polish to the disc 1. the frame 30 is rocked continuously on the shafts 15 by a cable H', Fig. 2, operated while the workpiece 32 is being rotated in contact with the disc. The cable H<SP>1</SP> is fixed to a bracket 24 on the slide 18 and oscillates the frame with the assistance of a spring 23, rocking motion being limited by an adjustable stop 37 on the slide. During withdrawal of the frame 30, effected by a spring 25, the rocking motion produced by the cable H' is stopped and the lever 10 returned by the spring 14. As the lever is returned, a pawl 34, Fig. 1, rotates a pawlwheel 8<SP>1</SP> and a sprocket 8, a further pawl 9 slipping to allow this rotation. A chain 6 is driven by the sprocket 8 to project the cake 3 from its housing 4 by moving a back-plate 33 attached to the chain. The plate 33 may be withdrawn by a handle 5, and the extent of each projection of the cake to compensate for wear may be adjusted by varying the position of the link 39, 42, 44 on the levers 10; 13. To compensate for wear of the disc 1, it is coupled (not shown) to a shaft on which a pinion 21 is mounted freely. This pinion meshes with a fixed rack 22 and a rack 20 on the carriage 19 so that any adjustment of the spindle 1<SP>1</SP> of the wheel 1 produces an adjustment of the carriage 19 of twice the extent of the adjustment of the wheel.

Filed: 1920-06-26
Abstract: 146,216. Huberty et Cie, F. Oct. 3, 1913, [Convention date]. Vinegar.-The serum obtained as a by-product in the manufacture of casein is made suitable for the preparation of vinegar containing milk sugar by removing the soluble albuminoid contents, (a) by precipitating with tannin, (b) by concentrating the serum in vacuo and precipitating the albumen by alcohol, (c) by evaporating the serum to dryness in vacuo and taking up the residue with the water of distillation, the albumen remaining behind undissolved. In each case, the precipitate is separated at ordinary temperature under pressure. The filtrate is then diluted with alcohol, alcoholic fermentation being thus avoided, and fermented by means of Mycoderma aceti, and the vinegar formed is led into the usual containers through a filter composed entirely of wood and canvas. Specifications 16302/03 and 21865/04, [both in Class 49, Food &c.], are referred to.

Title: Improvements in and relating to the production of alkali cellulose for viscose
IPC: D01F2/08
Filed: 1948-07-02
Abstract: Cellulose is converted into alkali cellulose for viscose manufacture by treatment with 17-25 per cent aqueous caustic soda solution in the presence of oxygen and an alkali-soluble diazonium hydroxide.  The ripening period is thus eliminated or reduced. Benzene diazonium hydroxide is preferred.  The process may be carried out as a slurry process by mixing the cellulose, caustic soda and diazonium hydroxide and passing air or oxygen into the slurry, preferably as a finely divided rapid stream whilst mechanically agitating.  If desired, cellulose sheets may be steeped in the caustic soda solution containing the diazonium hydroxide in the absence of air or oxygen, pressed and shredded in a Pfleiderer mixer so that air is freely accessible during the shredding.  The alkali cellulose is xanthated by the normal procedure when the fluidity of the cellulose has reached the desired figure (determined on cuprammonium solutions). In an example (all parts by weight) 15 parts of wood pulp sheets are steeped in 85 parts of 5.5N caustic soda containing 0.005 per cent benzene diazonium hydroxide and pressed hydraulically to give 45 parts impregnated pulp which is disintegrated in an open Pfleiderer mixer at 25 DEG  C.  Specifications 13055/14, 14675/14, [both in Class 2 (ii)], 467,500 and 642,843, [Group XXXI], are referred to.

Title: Improvements in or relating to telephone impulse transmitters
IPC: H04M1/278
Filed: 1963-05-07
Abstract: 1,037,812. Impulse transmitters. WESTERN ELECTRIC CO. Inc. May 7, 1963 [May 8, 1962], No. 17935/63. Heading H4K. The digits of a telephone number to be called are encoded on a code-bearing medium which co-operates with code-translating means to control an impulsing relay connectible to the telephone line, the impulsing relay being energized by the telephone line when connected thereto and interrupting the telephone line when energized. The digits are encoded in the form of rows of holes in a card which is inserted into the impulse transmitter, winding a spring which on release of a latch drives the card stepby-step past scanning means comprising spring- loaded feelers which operate contacts according to the arrangement of holes in the card. These contacts form a switching matrix together with other contacts controlled by an encoded drum which rotates through one revolution for each advancement of the card, the matrix controlling a blanking relay which when energized shunts the impulsing relay so that the number of impulses sent over the line at each step corresponds to the encoded digit being scanned.
