Title: Improvements in and relating to the delivery of cakes and the like from baking tins
IPC: A21B3/18
Filed: 1938-03-25
Abstract: 513,064. Endless-chain conveyers. PICKLES, J. D., NEWBOULD & SON, Ltd., J., and BAKER PERKINS, Ltd. March 25, 1938, No. 9246. [Class 78 (i)] Relates to the extraction of sponge cakes, buns, or like confectionery from the tins in which they are baked. The baking tins 7 pass from the travelling plate oven 6 down a shoot 9 to a lateral series of vertical guide members 13 terminating in a horizontal bar 14. The impact dislodges the cakes which fall forwards on to the conveyer 15 at the same time as the pans fall backwards on to the conveyer 16. If the tins in a row on the oven 6 are not in alignment, they are-retained on the shoot 9 by pivoted flaps 17 until the row is completed, and are then released simultaneously to fall upon the bar 14. As each tin slides down the shoot, it closes a tiltable mercury switch 19, and when all the switches are closed a magnet 22 is energized to withdraw the flaps.
Patent GB-659932-A (GB)
Title: Improvements in or relating to record changing phonographs
IPC: G11B17/16
Filed: 1949-04-05
Abstract: 659,932. Automatic gramophones. HOLSTENSSON, A. H. April 5, 1949, No. 9250. Convention date, April 6, 1948. [Class 40 (ii)] A record-changing device comprises a fixed centering pin 2 about which the turntable 3 rotates. The pin has a longitudinal slot 7 which, towards the upper end, is cut right through the pin opposite to a recess 4 forming a supporting shoulder 5. Inside the pin 2 and movable in the slot 7 is a record-changing rod 8 formed at its upper end with a supporting shoulder 19, recess 9, and finger 10. A stop member 12 is tiltably mounted in the upper end of the pin 2 and can move longitudinally under the control of a spring 11. Stop 12 has an arm 15 and an arm 16 that rests in recess 9 of rod 8. A stack of records 6 is threaded on pin 2 and rests on the shoulder 19 of rod 8 which is moved to this position (Fig. 1) by the record-changing mechanism (not shown). To change a .record the rod 8 is turned clockwise to remove the shoulder 19 and allow the lowest record to fall (Fig. 2). The stop member 12 rotates and arm 15 displaces the remaining records to the right so as to be supported on shoulder 5 on pin 2. The rod 8 is then moved upwards to lift the records off the shoulder 5, and then rotates anticlockwise to move shoulder 19 outside the pin 2 and lower the remaining records into the original position shown in Fig. 1. When the last record has fallen, rod 8 moves up under the action of a weak spring (not shown) to stop the gramophone at the end of the record. Alternatively, the normal static position may be that of Fig. 2, the records resting on the shelf 5. After playing, when records are removed from the pin 2 they force rod 8 inwards so as to lie within the pin. The uppermost record then engages the end of arm 15 to move stop 12 upwards against the action of spring 11 until the edge of the recess in the pin turns member 12 clockwise so as to lie within the pin, thus allowing the records to be removed.

Title: Improvements in or relating to methods of and means for printing
IPC: B41F17/00
Filed: 1946-03-26
Abstract: 619,224. Printing machines. GOSS PRINTING PRESS CO., Ltd. March 26, 1946, No. 9376. Convention date, March 26, 1945. [Class 100(ii)] In printing apparatus of the kind in which ink is transferred from a printing surface 10, Fig. 1, or 50, Fig. 4, under the influence of an electric field of force, the web is fed so as to touch the ink with slight pressure instead of being definitely separated from the inked surface. In Fig. 1, the inked cylinder 10 is connected to earth and the coacting cylinder 16 is connected via a variable resistance 22 to the positive pole of a source of high potential 21 which is also connected to earth. Preparatory to the printing operation, the web 14 is charged positively with static electricity by passage over a mass 15 of silver, or other material which will charge paper positively, and from this the web passes directly to the printing line. This is protected by wedges 19, 20 of plate glass separated by a short distance, and the roller 16 is covered with a layer 16b of conducting rubber. In a modified form of apparatus a metal roller is interposed between the'cylinder 16 and the resistance 22, and the roller 16 as well as the roller 10 is connected to earth. A condenser effect is thus formed between the rubbercovered cylinder 16 and the positively charged metal roller. In a further modification, Fig. 4, the positively charged electrode 68a is protected by a glass hood 66 and is arranged at a distance from the printing roller 50. The hood 66 is adjustable by means of a screw 70, and the side 66b of the hc.od is arranged at a higher level than the side 66c, so as to permit the web 54 when charged by the silver member 55 to engage the roller 50 without contacting the side 66b. Specifications 604,012, 608,902 and U.S.A. Specifications 1,820,194 and 2,224,391 are referred to.

Title: Process for separation of acetic anhydride and acetic acid
Filed: 1931-03-27
Abstract: Acetic anhydride is separated from its liquid mixtures with acetic acid which may contain a non-aqueous solvent such as toluene, chlorinated hydrocarbons, ethers and esters, by cooling to a sufficiently low temperature, to cause the crystallization of the acetic acid.  The mixtures may be cooled by external cooling and/or by adding a freezing material such as solid carbon dioxide.  In examples (1) a mixture of 20 parts acetic acid and 50 parts acetic anhydride is cooled to -70 DEG  C.; (2) a mixture of 25 parts acetic acid, 15 parts acetic anhydride, and 65 parts toluene is cooled to -68 DEG  to -70 DEG  C.  The anhydride may be separated from the toluene by distillation, or, where an organic solvent is to be present in a process of acetylation, the mixture of such solvent and anhydride may be used for the acetylation as it is.

Title: Improvements relating to particle accelerators
IPC: H05G1/62
Filed: 1955-03-31
Abstract: 776,802. X-ray apparatus. GENERAL ELECTRIC CO. March 31, 1955 [March 31, 1954], No. 9449/55. Class 98(1) [Also in Group XL(a)] The pulsed X-ray output from a betatron or synchrotron particle accelerator is synchronized with the recurrent motion of a body for the purpose of taking stroboscopic radiographs. Particles are only injected into the accelerator when its accelerating cycle begins within a fixed time interval after the body reaches a triggering position. At the end of the time interval the particles bombard an X-ray target. Trigger pulses B are derived from voltages induced in coil 9 by a cam 6 connected to the moving object through a shaft 5 and fed to differentiating circuit 13, 14. Pulses B trigger multivibrator 15 to produce square wave pulses C which are fed to a coincidence switch 27 together with signal pulses A from the injection timing circuit 3 of the accelerator. Pulses E from coincidence switch 27 are fed to injection circuit 38. Pulses D produced at the ends of square wave pulses C by differentiating circuit 24, 25 are fed to the ejection circuit 36. In a modification output pulses G are fed to the ejection circuit only when particles are actually injected into the accelerator. Pulses G are derived from a second coincidence switch to which are applied the pulses D and square wave pulses F which are produced in a second multivibrator by pulses E. In order to obtain exact synchronization between X- ral bursts and the moving object, the end of square wave pulse C is determined by a second trigger pulse B<SP>1</SP> which is derived by providing a second tooth on the cam 6. Interval BB<SP>1</SP> varies with the speed of the moving body. Specifications 574,812, 589,348 [both in Group XL] and 622,148 [Group XL(a)] are referred to.
