Patent GB-883325-A (GB)
Title: Phantastron circuit
IPC: H03K4/56
Filed: 1960-01-13
Abstract: 883,325. Valve pulse-generating circuits. NATIONAL CASH REGISTER CO. Jan. 13, 1960 [Feb. 4, 1959], No. 1213/60. Class 40(6). In a cathode-coupled phantastron circuit in which the duration of the voltage run-down at the anode may be varied without changing the rate of voltage run-down, the output sweep voltage is compared with an adjustable reference voltage in a circuit which when the sweep voltage falls below the reference initiates resetting means to restore the circuit to its quiescent state. The emitter of a transistor Tl is baised to a voltage +ET derived from a potentiometer R20 connected across the voltage source El while the base electrode is connected to a tapping point on the output circuit, so that when the sweep voltage at the anode of the phantastron valve Vl, as translated by the cathode-follower V3, falls below a predetermined value, the transistor T1 conducts so sending its collector electrode positive and thus applying a positive resetting voltage to the control grid of V1 through the diode D. In a modification, Fig. 4 (not shown), the collector of transistor Tl is connected to the base of a NPN transistor which is switched on when Tl conducts to apply a negative resetting voltage to the suppressor grid of the valve V1. In addition to the control already provided, the amplitude of the output sweep voltage may be varied without affecting its duration by means of the potentiometer R9 while adjustment of variable resistor R8 permits the duration to be varied without change of amplitude.

Title: Improvements in dough proofers
IPC: A21C13/00
Filed: 1928-01-16
Abstract: 291,422. Baker Perkins, Ltd., (Assignees of Devlin, H.). June 4, 1927, [Convention date]. Proving-appliances.-In a prover having pivoted pocketed trays carried on an endless conveyer, a loader delivers a dough piece to a pocket, e.g., the first, second or third pockets, of each tray as it reaches the loader, and the trays are tilted at a predetermined point in their path, the dough pieces being guided by shoots into relatively offset pockets of a preceding tray, the dough pieces from the last pockets, however, being guided by a shoot to the discharge point. As shown in Figs. 2 and 3, the trays 4 have six pockets 7 and are pivotally carried on chains 5 trained over sprockets 6. The loader comprises, in its simplest form, a shoot 15 receiving dough from the divider and delivering it into a spout 16 aligned with the first pockets of the trays. The spout 16 is closed, in synchronism with the trays, by a feed timing gate 17 which is operated by a lever 19 and a cam 18, on the lower sprocket shaft. The first pockets are charged continuously and the trays are tilted at the discharge position by engaging a cam rail 13. The dough pieces fall through inclined shoots 12 into relatively offset pockets of the second tray ahead. The dough from the last pocket of the tilted tray is discharged through the shoot 3 to a sheeting and rolling machine. With this arrangement, each dough piece is transferred to another tray several times and is turned or inverted during its transfers. Two alternative methods are described for varying the proof time without altering either the rate of feeding dough to the machine, or the conveyer speed. In one method, Fig. 2, three spouts 16 are provided, and adjustable baffles 22 co-act therewith to feed the dough into the first, second, or third pockets of the trays. The dough pieces are thus traversed through the machine six times when fed into the first pockets, five times when fed into the second pockets, and four times when fed into the third pockets. In the other method, Fig. 5, the inclined shoots 12 and the discharge shoot 3<a> are slidable bodily so that the dough pieces can be discharged from intermediate pockets or from the last pockets.

Abstract: 864,179. Injection-moulding machines. FEMCO MOULDING MACHINE CO. Ltd. Jan. 13, 1960 [Jan. 19, 1959], No. 1881/59. Class 87(2). An injection-moulding machine, of the type having a fixed injection head for injecting plastic material into moulds as they are successively indexed on a rotary table below the head, comprises a camshaft adjacent to and having a part directly engaging the outer edge of the table, which camshaft controls in timed relationship the table-indexing mechanism, the feeding assembly for the injection head, means for locking the indexed moulds, and the means for injecting the material from the head into the mould at the injection station. A rotatable table comprises spaced circular plates 10, 11 each having a ring of apertures which in plate 10 support the upper mould parts 12 and in plate 11 allow the passage of plungers 8 which carry the lower mould parts 13. The table is intermittently rotated by the driving arm 27 of a Geneva mechanism 26 carried on a main vertical shaft 28 driven by motor 6; which arm carries a roller which engages slots in plate 11, Fig. 2 (not shown), and recesses between each slot are successively engaged by a lobe 30 of said mechanism to ensure accurate mould positioning. Plastic material is fed to pre-plasticising unit 92 containing a heated torpedo 96 and from thence to the injection cylinder by a plunger 108 connected via yieldable transmission to a shaft 118 reciprocated from crank 111 on shaft 28 via rods 112, 114, rack 115, shaft 116 and rack 117. A plate 124 attached to plunger 108 operates an adjustable metering pusher 126 which feeds forward granular material from hopper 103. At each station the plunger 8 is forced upwardly to lock the mould against the injection nozzle 49 by a toggle mechanism 83 which is straightened via link 85 and arm 84 under the action of cam 88 on shaft 28 and later collapsed by a further cam 86 on this shaft. Cam 79 on shaft 28 actuates microswitch 80 to energise the solenoid of valve 71 which allows the passage of oil through pipe 72 to the top of piston 44 in cylinder 42 and thus causes the injection stroke of plunger 45. Figs. 5 and 6 (not shown), illustrate a threaded cap member 139 produced by the apparatus between the two part members 12 and a core in member 13 which core is rotatable to release the article ; the broken sprue being blown away by an air jet. Rollers 136 running on track 137 and attached on arms to the bottom of plungers 8 control the opening and closing of the moulds, and the stripping of the article 139 is controlled by a roller 146 in a cam groove 147 in a block 148 keyed to the shaft 28.
