[Class 44.] Furniture such as a pedestal desk 2 in which the closure of a master drawer 6 having a key lock permits the movement of a vertically sliding locking-bar 1 with lateral fingers 4 engaging recesses in the sides of the master and subsidiary drawers 3 whereby the latter are automatically locked has the master drawer provided with a second recess 5a, at the inner end, whereby this drawer 6 is prevented from being removed from the desk and when fully pulled out likewise locks the subsidiary drawers 3. The fingers 4 may run on metal plates 9 cut to correspond with the recesses 5, 5a and attached to the sides of the drawers. Figs. 7 and 8 show alternative means which permit a subsidiary drawer to be closed after the master drawer has been closed. Fig. 7 shows the side face of the drawer cut away at 11 so that the bar 1 may drop (to lock the other drawers) when the master drawer is shut while on subsequently closing this subsidiary drawer the bar 1 is raised by the slope 12 and then drops again with finger 4 now locked in the square recess 5. Fig. 8 shows the fingers 4 slidably mounted in recesses 14 on the bar 1 and urged downwards by weak springs 15. Should a subsidiary drawer be left open when the master drawer is shut the finger 4 corresponding to such subsidiary drawer remains up on the stop edge of the side wall until such time as the drawer is pushed in whereupon the finger 4 springs into the square recess 5 to lock this drawer. The bar 1 is urged downwards by a strong spring 7. A metal plate 6a protects the underside of the master drawer 6.

IPC: C25D1/06
Filed: 1920-11-26
Abstract: 176,456. British Thomson - Houston Co., Ltd., (General Electric Co.). Nov. 26, 1920. Silvering.-Relates to surface-coated metal mirrors made by depositing silver or other reflecting metal on a glass form, backing it with another metal or cement or both, and then removing the whole from the form. According to the invention the deposit of reflecting metal is strengthened by an electrolytic deposit of silver; good electrical contact is obtained by painting a band of conducting material around the edge of the mirror. A search-light mirror is made as follows. The convex surface of a ground and polished form 2, Fig. 2, is covered with a chemical deposit 3 of silver, which is reinforced by an electrolytic deposit 5 of silver. The edge of the chemical deposit is first covered with a bronze lacquer annulus upon which is clamped a brass angular edge ring 7 by means of clamps 10 secured to a spider 4 supporting the form 2; an open space 9 is left between the lower outer edge of the ring 7 and the form. An electrolytic layer 15 of copper is then deposited upon the electrolytic layer of silver; in cases where the mirror is to have a central opening a ring 14 is placed on the electrolytic silver layer before depositing the copper. The mirror is then backed with a layer 17, Fig. 5, of cement, such as Portland cement or plaster of Paris, an adhesive such as linseed oil or linseed oil and ground pumice, or oil paint with sand dusted thereon being employed. The cement may be reinforced by a metal shell 18 formed in sectors and with perforations 19, through which cement passes to rivet the shell in place. The mirror is then removed preferably by means of compressed air nozzles introduced into the open space 9 at the edge. A colourless lacquer is then applied to the chemical silver deposit.

Title: Process for stabilising organopolysiloxane polymers
Filed: 1957-10-29
Abstract: Organopolysiloxanes having a viscosity above 100,000 cs. at 25 DEG C., and obtained by the action of 0.0001 to 0.01% of an alkaline agent on a siloxane having a ratio of about 2 hydrocarbon radicals per Si atom, are stabilized by adding thereto from 0.1 to 2.5% by weight of a finely divided silica obtained by precipitation or combustion and consisting of particles having a mean diameter less than 1000 m m  and a specific surface area of at least 50 m2/gram. The treated siloxane gums may be freed from the volatile constituents contained therein by heating, and may then be converted into elastomers by the addition of a filler which may be a silica as used for stabilization, and vulcanizing agent in a known manner.  In Examples: (1) a methylpolysiloxane gum and (3) a methylvinylpolysiloxane gum are stabilized in the above manner.

Title: Controlled feeding means for machines for slicing bread and the like
IPC: B26D7/27
Filed: 1957-11-01
Abstract: 829,340. Feeding bread for slicing. PACKAGE MACHINERY CO. Nov. 1, 1957 [Jan. 7, 1957], No. 34131/57. Class 5(1). [Also in Group XXX] Sliced loaves operate detector fingers 30 and are carried to a wrapping machine and pass to a cross machine and pass to a cross conveyer 38 to the wrapping machine, the fingers 30 operating to stop the in-feed of the loaves to the slicer and start the carry away feed from the slicer in timed relation to the cyclic operation of the wrapping machine. A sliced loaf entering the exit station 22 depresses fingers 30. Switch SW1 assumes its normally open position as block 164 moves away from its switch plunger. Opening of switch SW1, Fig. 2, deenergizes solenoid S1 and allows pawl 156 to drop to engage ratchet 158 to stop end belts 14 to stop the feed-in of loaves to be sliced. Pawl drop thus moves it away from plunger of switch SW2 whereby solenoid S2 is energized. Assuming that lever 98, Fig. 5, has been rotated to counterclockwise position by cam 140 the stop 102 allows latch 104 to be drawn in from stop 102. Rotation of cam 140 to position, Fig. 7, permits lever 98 to rotate clockwise to release pawl 120 so that it places disc 124 in driving engagement with sprocket 98 thus starting the discharge conveyer 34. Sprocket 58 has a predetermined relationship with the cyclic operation of the wrapping machine. Thus whenever pawl 120 engages a tooth 126 the conveyer 34 will be moved in predetermined timed relationship to the cyclic operation of the wrapping machine. When disc 124 is in driving relationship with shaft 90 the cam 146 is also rotated, so that shortly after, cam 146 allows lever 136 to rotate to displace link 148 to the left and raising pin 154 to bring pawl 156 away from ratchet teeth 158 so that belts 14 begin to feed a loaf to the slicers 18.

[Class 51 (ii)] In a furnace having a conveyer consisting of driven rollers 8 carrying charge - supporting discs 10, the rollers 8, which rest on one or more bearings 12 within the furnace chamber, terminate, at one end, short of the side wall 2 and, at the other end, have extensions 38 which pass through apertures in the opposite wall 2 and are connected by flexible couplings 42 to driving shafts 44. The latter are driven through bevel gearing 48, 50 from a shaft 52, and the apertures through which the roller extensions 38 pass are sealed by heat-insulating material 54 enclosed in sheet metal containers 56. Each bearing 12 comprises a pair of rollers supported in bearers 14 secured to the upper end of a pedestal 16 which is adjustably mounted in the furnace floor 6. As shown in Fig. 1, the pedestal has secured to its lower end a wedge-shaped part 30 resting on a similarly shaped member 57 which is moved horizontally, to raise or lower the pedestal, by a shaft having a crank handle 61 at its outer end. The roller 8 is retained in position on the bearing rollers 12 and access of dirt and scale to the latter is prevented by a two-part hood 26 which is welded at 28, Fig. 3, to the supports 14. Fig. 7 shows a modified form of bearing in which, in addition to the rollers 60, there is provided an additional " floating " roller 64 which rests on top of the roller 8 and is mounted for free vertical movement in recesses 66 in a yoke 68. The arrangement of bearings shown in Fig. 1 is modified for exceptionally narrow or wide furnaces ; in the former case one bearing is disposed within and another outside the furnace, while for wide furnaces each roller 8, which is formed in two sections connected by a flexible coupling, is supported by three bearings within and one outside the furnace chamber. Fig. 13 shows, in plan view, a further construction in which the rollers 8 are arranged in groups, the rollers of each group being connected by driving chains 106 and the end roller only of each group extending through the furnace wall 2 for connection through a flexible coupling 42 to the driving gear 48, 50. The main driving shaft 110 is formed in sections between which are provided change-speed mechanisms 114 to enable the speed of the several groups of rollers to be varied as desired. In this construction each roller 8 is supported within the furnace by two bearings, one being of the form shown in Fig. 3 and the other as shown in Fig. 7.
