Abstract: 646,307. Endless conveyers. HALFORD, Ltd., E. R., and HALFORD, B. March 8, 1948, No. 7073. [Class 78 (i)] [Also in Group VI] Apparatus for handling tins or like receptacles used, for example, for baking bread, comprises means for propelling the tins and guiding means which include a loop or bend in which the tins are automatically inverted as their direction of travel is reversed, the guiding means also supporting the inverted tins. As shown, tins a containing baked loaves are placed on a conveyer consisting of a pair of parallel endless chains d having platforms extending there between for supporting the tins with projections c for propelling them. The conveyer carries the tins between a pair of rails f and then between a pair of vertical plates g, each having an arcuate groove h bounded by a flange i, the grooves being concentric with the chain sprockets j. As the tins are propelled round the grooves h, they are supported by wheels k whilst a guideplate m prevents the loaves dropping from the tins until these pass over a shoot o down which the loaves fall on to a conveyer n. The empty tins are then propelled by the projections e from the flanges i along supporting rails p until they come over a conveyer extending at right-angles to the chains d, on to which they fall to be carried away for re-filling with dough. The empty tins may be sprayed by a pneumatically-operated grease gun positioned beneath the rails p, the gun being actuated by a solenoid controlled by a mercury switch which is tilted by a lever operated by a projection on a disc mounted on a shaft above the rails and having fingers projecting into the path of the tins.

Title: Improvements in or relating to methods of making poppet valves, and the improved valves resulting therefrom
IPC: B23P13/00
Filed: 1945-03-22
Abstract: 604,290. Making poppet valves. THOMPSON PRODUCTS, Inc. March 22, 1945, No. 7268. Convention date, June 26, 1944. [Classes 83 (ii) and 83 (iv)] [Also in Group XXVII] Welding.-In the manufacture of hollow poppet valves having an insert for conducting heat away from the head, the stem is formed with a cavity, flared at its open end, which receives a sodium insert and a cap is resistance welded on to the open end of the stem, the stem having a convex rim forming a projector to concentrate the welding current, thus preventing heating of the sodium. More than one may be produced at a time; the stem 12 being fitted in a die block 14 of a die-holding fixture 15 in a welding machine. A sodium insert 16 is introduced into the flared cavity 13 of the stem and a cap 19, secured in a die block 20 of the upper die-holding fixture of the machine, is lowered on to the projection 18 of the body. This projection serves to localize and concentrate the welding current to effect welding without increasing, greatly, the temperature of the heat-conducting insert. Pressure is maintained and electric current passed to fuse the members together, forming a secure weld extending into both parts. The interior of the cavity may be polished as a preventative against fatigue cracks. The Specification as open to inspection under Sect. 91 states that a projection may be formed on the cap or on both the cap and the body. A modification is also described in which the valve is formed complete with head, but contains a central bore for the sodium insert, said bore being closed at its open end, after fitting the sodium stick, by a tapered plug member which is pushed into the cavity and is welded to the edge thereof, the head surface being afterwards finished by grinding to present a smooth contour. This subject-matter does not appear in the Specification as accepted.

Filed: 1924-03-24
Abstract: 235,941. Automatic Telephone Manufacturing Co., Ltd., and Tench, F. March 24, 1924. Automatic and semi-automatic exchange systems.-Chain circuits are arranged to changeover (a) when a predetermined number of relays or off-normal springs become operated or (b) when a predetermined number fall back, certain of the relays controlling a number of contact points equal to the " predetermined number." The former arrangement may be used to control the driving magnet of a switch for allotting a piece of apparatus common to a number of operators. If only one operator needs the apparatus the chain is held open, but when two or more need it, it is closed to ensure that each operator gets it in turn. The second arrangement may be used when a group of secondary line switches is to be marked busy when all but one of the switches have been taken into use. The chain shown in Fig. 2 is closed and that in Fig. 8 opened whenever three or more of the relays are operated. That shown in Fig. 4 is closed when all the relays are operated and opened when three or more have fallen back. That in Fig. 6 is open when the relays are all operated and is closed when three or more have fallen back.

In a vacuum bottlefilling machine comprising a liquid container, 20 supplied with liquid by a pipe 12, maintained under vacuum by a pipe 19 and provided with peripheral filling nozzles each having a filling pipe 23, a vent pipe 26 extending above the liquid level in the container 20 and a sealing member 25 acting with a bulged part 28 of the vent pipe to form a liquid valve which is opened by a bottle neck engaging the member 25, the degree of vacuum can be adjusted by rotating a valve 16 and the pipe 26 has sufficient volume above the level 31 of liquid in the container to contain all the liquid withdrawn from the bottle through the pipe 26 when the seal between the bottle and the nozzle has been broken. In filling bottles of different nominal capacities, it will be necessary to remove different quantities of liquid from the bottle after the seal has been broken. The amount of liquid withdrawn forms a hydrostatic head in the tube 26. This head depends on the difference between the atmospheric pressure and the vacuum pressure applied. Therefore, by selecting the correct position of valve 16, the desired amount of liquid can be withdrawn from the bottle. The valve 16 rotates in a housing 9 and comprises a cylindrical member tapered at 17 and provided for rotation with a projection 34 and lock-nut 35 projecting through a peripheral slot in the housing 9. The level in the container 20 is maintained by a float 33 and valve 36. The nozzles are moved down into engagement with the bottles by means 30.
