Patent GB-175998-A (GB)
Title: Improvements in dough dividing machines
IPC: A21C5/08
Filed: 1922-02-24
Abstract: 175,998. Bertram, O. Feb. 24, 1921, [Convention date]. Dough dividing and working machines; rolling- machines.-In a machine for pressing, dividing, and kneading dough, having fluid-operating mechanism comprising a press plate, a yieldable counter plate and a dividing-appliance which moves through said counter plate when it has yielded, the counter plate is positively locked until the pressing operation is completed and is then released so as to yield to the advancing press plate. The dough rests on a press plate 36 supported on a hollow piston 35 inside which reciprocates a piston 34 so as alternately to compress and expand the air in the chamber 64. The piston is driven through worm gearing 28, 29 by the shaft 4 which is rotated intermittently from the shaft 25, the clutch 8, 10 being thrown in and out of gear by a lever 12 pivoted on a support 13 and moved to the right or left according to the position of the roller 17 in the cam groove 18. Initial compressiom of the air causes the plate 36 to rise and compress the dough against the counter plate 48 locked in position by a bolt passing through the spindle 56. Further compression causes the spring-controlled valve 41 to be opened and this allows air to flow along the passages 3, 43 and operate the piston 44 so as to lift the push 45 and release the bolt which holds the plate 48 in pcsition. The latter along with the plates 36 then rises owing to the pressure in the chamber 64 and the dough is pushed into the compartments formed by the cutter 50. The lever 12 is then actuated by the cam mechanism to throw the shaft 4 out of gear and simultaneously engages the shaft 6 through the clutch 9, 11. Motion is thus imparted through worm gearing 54, 55 to the sleeve 52 thus rotating the plate 48 and kneading the dough, said plate 48 being counter-balar ced by a weight so as to yield to the rising of the dough. Further motion of the cam 24 declutches the shaft 6 and re-starts the shaft 4. The piston 34 is thus retracted and the exhausion of the air causes the descent of the plate 36 which on its path strikes the gear 47, thus opening the valve 46 and allowing the compressed air in the pipes 43 to escape.

Abstract: 1,220,874. Jointing by stamping; making pipe fittings. H. MATSUMOTO. 2 Feb., 1968 [4 Feb., 1967], No. 5549/68. Headings B3A and B3Q. [Also in Division F2] In a method and means for securing a fitting 4 having a circular internal bore and a hexagonal periphery on a pipe 1 two tools 6 and 7 are moved towards each other and engage the fitting so as to exert four angularly directed compressive forces 16, 16; 17, 17 to produce an elliptical internal cross-section and then two forces 22, 23 in the direction of movement of the tools to make the bore of the fitting circular and closely fitting on the pipe. The hexagonal faces of the fitting are preferably convex. A fitting is made by first forming it with dimensions corresponding to the final dimensions to be achieved, and then expanding it by means of a conical tool to a larger diameter. The fitting is then placed in tools similar to 6 and 7 and compressed. If the internal cross-section is circular after the compression this represents the final form of the fitting. If, however, a non-circular cross-section is obtained as in Fig. 10 then the dimensions of the thickness of the fitting are increased or decreased by amounts S 2 , S 1  to obtain the desired final form for the fitting.

Abstract: 564,929. Riveting. BRITISH UNITED SHOE MACHINERY CO., Ltd., and COOPER, B. P. April 8, 1943, No. 5593. [Class 43] A tool for pop-riveting comprises an abutment 11 to engage a rivet head, means to engage a portion of the mandrel stem M to bend it out of alignment with an adjacent stem portion, and means arranged to cause rectilinear movement of the bending means axially of the rivet to impart a pull to the mandrel stem when in the bent condition. A slide 19 comprises a base-plate 21 having grooves to receive the mandrel stem on either side of a gap 31, the groove nearer the abutment plate 11 being serrated. A slide 41 above the base-plate guides three plungers 33, 35, 37, the first and last being opposite the grooves and the middle plunger opposite the gap and bevelled to an edge. The plungers have heads normally urged outwardly by springs 59 and engaged by a plate 45 co-operating with a cam 53 actuated by a hand lever 51 for bending the mandrel stem. The slide 19 is moved to give the usual pull to the mandrel by a hand-actuated lazy tongs connected to a rod 63. A spring plunger 60 ejects the mandrel stem when the grip is released.

[Class 38 (iv)] A circuit arrangement for a discharge lamp 10 having filamentary electrodes 11, 12, which provides a high starting voltage across the electrodes and automatic reduction of heating current to the electrodes whilst the lamp is operating, comprises a swinging choke 16 included in one of the supply leads to the lamp electrodes and a heating transformer 18 comprising two secondary windings 20, 21 connected to the respective electrodes and a primary winding 19 connected at one end to a tapping 24 on the choke 16 and at the other in series with the secondary winding 20 to that supply lead 14 connecting the electrode 11 direct to a supply terminal, the core cross-section of the transformer being substantially greater than that of the choke so that during preheating the choke functions as an auto-transformer to provide the high voltage across the lamp, and upon initiation of the lamp discharge the voltage drop increases across that portion of the choke remote from the lamp to lower the heating current. A condenser may be shunted across the lamp to facilitate starting and the transformer and choke may be loosely coupled.
