Title: Improvements in continuous baking and the like machines
IPC: A21B5/02
Filed: 1952-01-17
Abstract: 692,917. Rotary mould table machines for making crumpets. GLEADALL, L. R., HARRIS, B. R. and MILICICH, J. Jan. 17, 1952 [Feb. 19, 1951], No. 1387/52. Class 87 (ii) [Also in Group VI] Crumpets 22 are continuously baked in frame moulds 23 resting on a series of radial hot plates 18 between the spokes 10<SP>3</SP> of a horizontal rotated carrier 10 the moulds 23 being supplied with a measured quantity of dough material and after cooking on the hot plates during carrier rotation, the moulds are raised in turn from their crumpets, and the hot plates are rocked along their radial trunnions 19,'20 to discharge the crumpets downwards. Fig. 6 is a straight line development of the apparatus. By the time the crumpet is cooked, each mould holder 25, Fig. 8, is pivoted up about 45 degrees by a fixed cam plate 34 engaging a crank arm 28 on a spindle 27 forming a hinge for the mould holder 25. Each hot plate 18 is then rotated through 180 degrees by a pinion 36 travelling into engagement with fixed toothed racks 37. The crumpet is then stripped from the inverted hot plates 18 by contacting fixed stripper knives 39 pivoted on a guide plate 38. A second toothed rack 37 rotates each hot plate 18 through a further 180 degrees to restore it to dough receiving position. The moulds 23 then pivot back on to their hot plates by their weight.  The strippers 39 are so weighted as to keep their edge in contact with the hot plate. The edge of the stripper 39 is protected by a horn 41 projecting beyond its edge. If both sides of the hot plate are made flat, only one rotation through 180 degrees is necessary to bring the other flat side into cooking position. The moulds 23 are loosely secured to the holder 25 by pins fitting in clearance holes 23 in the mould holder 25. When the hot plates are heated by electricity the supply from bus bars 47, 48 Fig. 8 is interrupted during turn over of the hot plates when flexible contact strips 45 also turn over. When heated by gas jets the hot plates are made to abut substantially to resist flow of the hot gases between them, and a casing may be arranged over the cooking arc of the machine. Radiant heat may be supplied to the top of the crumpets by another superposed hot plate. Dough of the consistency of a paste in a central air pressurized hopper (50 not shown) is supplied to a pair of diametrically opposed radial tubes 52, and from them through valves to an empty set of moulds. A projection on the mould set trips an arm to rotate an inner tube 53 Fig. 6 to register slots 54 with slots 55 whereby dough paste is discharged into the moulds.

Patent GB-1361156-A (GB)
Title: Digital sweep generator in video storage device for a radar data display system
IPC: G01S7/28
Filed: 1973-01-10
Abstract: 1361156 Pulse radar; cathode-ray tube displays BENDIX CORP 10 Jan 1973 [16 Feb 1972] 1397/73 Headings H4D and H4T A pulse radar display is supplied with digitized radar returns, a digital storage system being provided between the radar receiver and display and comprising a circulating digital memory fed by an input buffer store allowing the rate at which bits are entered in the memory to be varied, an output circuit feeding the display device and allowing the read out of stored data at a rate differing from that at which data is entered into the input buffer. Fig. 1 illustrates the input section of the system, the digitized return being fed to buffer 11, capable of storing two words, each corresponding to a particular range sweep. The data is entered into the buffer at a rate determined by divider 15 which determines the display range. Counter 20 allows only one word to be stored at a time. Two words are stored consecutively in buffer 11, the words corresponding to consecutive range sweeps and are then transferred at frequency fo to memory 26 under control of the remaining logic circuitry. Once memory 26 is updated access to it from buffer 11 is disabled and the data in memory 26 is continually recirculated. The data in memory 26 is passed to an integrator (Fig. 2, not shown) which tends to eliminate straneous bits. An azimuth control (Fig. 2, not shown) synchronizes the operation of the system and radar antenna. The integrated data is fed to a memory (Fig. 3, not shown) which is split into two parts necessary for updating purposes. An output buffer connected to the latter memory comprises two shift registers 160, 162. One shift register stores a word from the latter memory during which time the other shift register reads out a previously stored word at a higher rate the register, alternating from storing to reading from word to word. In the embodiment a word is read out twice as fast as it is stored and is read out twice to a digital to analogue converter (168) (Fig. 4, not shown), feeding a CRT (170). The higher read out rate enables the production of a bright flicker-free display from radars operating at low P.R.F.s.

Patent GB-766443-A (GB)
Title: Improvements in or relating to device for locating recorded information on a recording medium
IPC: G11B27/06
Filed: 1954-01-18
Abstract: 766,443. Magnetic recording apparatus. TECHNICOLOR MOTION PICTURE CORPORATION. Jan. 18, 1954 [Jan. 19, 1953], No. 1473/54. Class 40 (2). A magnetic tape 12 is driven between spools 14, 15 by a motor 30 and is scanned, e.g. for editing the tape, by a magnetic head 42 which is reciprocated by a crank 75. Alternatively the head may be held stationary whilst the tape is reciprocated over it, the recorded signal being fed to a loud-speaker 50. When a region is reached where it is desired to cut the tape, the motor 30 is stopped to stop the tape, and a motor 57 started to oscillate the head 42, the recorded signal is fed through a switch 55 to an oscillograph 52. The oscillograph has a time base sweep controlled by an alternating voltage source 87 which also energizes the motor 57. A still representation 90 of the recorded signal is therefore produced. To accurately mark the spot where the cut is to be made, a magnet 100 is mounted on a manually movable lever which also carries a punch (Fig. 5, not shown). The magnet 100 produces an image 103 on the oscillograph. The lever is moved until the mark 103 is moved to the desired point of the representation 90, and the punch depressed to mark the tape. If desired, the lever may be connected to the rotatable arm of a potentiometer, instead of carrying the magnet. In a modification (Fig. 4, not shown) a pair of magnetic heads may be mounted on opposite ends of a continuously rotated lever. The apparatus may be modified to represent several recordings on adjacent tracks on the tape. The tape drive rollers 17, 26 may be in the form of drive sprockets.

Abstract: 400,811. Electromagnetic switches; protective cut-out systems. ENGLISH ELECTRIC CO., Ltd., 28, Kingsway, London, and BAMFORD, W., 101, St. George's Road, Stafford. Jan. 20, 1933, No. 1917. [Class 38 (v).] - A transformer associated with a power line for operating measuring instruments, relays, protective gear, &c. is designed for a low output, the secondary winding being connected to a thermionic valve amplifier. The current transformer 1 is mounted in the bushing chamber of a'high voltage bushing through which passes the line 2 carrying the current to be measured. The core is of small dimensions and may have a large mean magnetic path without air gaps. Alternatively the core may have air gaps, or the transformer may be air-cored. The secondary winding is connected between the cathode 3d and grid 3a of a thermionic valve 3, the anode 3c of which is connected through resistances 6, 7 and condensers 8, 9 to the grid 4a of a second valve 4. In the output circuit of this valve are connected a relay 10 and ammeter 11 in series with a condenser. Other methods of interstage coupling may be employed, and the output stage may contain a number of valves. At an intermediate stage the amplifier may be tuned either to respond to, or to reject, one particular frequency or band of frequencies in order to render the instrument substantially unresponsive to transients in the line 2. The reactance of the circuit may be chosen so that the phase of the current through the relay 10 and instrument 11 may differ by a desired amount from that of the current in the line 2. The amplifier may include a rectifying valve so as to obtain a direct current output.
