Title: Privacy transmission system
IPC: H04K1/06
Filed: 1973-04-10
Abstract: 1382558 Secret transmission systems MULLARD Ltd 10 April 1973 17045/73 Heading H4R  In a secret transmission system, successive signal elements are stored, transmitted at a rate which varies over the period of each element and in a programmed, rearranged order, and the original order reconstituted after transmission. Signals at 17 are pulse-code modulated 18 successive elements fed to shift-register 5-7 (or core stores), via electronic switches 8-10 programmed by a multiplexes, and recirculated, all under clock pulse control CK1. Switches 11-13 are opened in scrambled sequence but in sync. with switches 8-10 to read-out at a variable rate CK2 switched at 14-16. The received signals are similarly read into registers 25-27 at rate CK2, rearranged and read-out at. rate CK1 and demodulated. The rate CK2 may vary pseudo-randomly in programmed manner in successive time periods. A random generator (Fig. 2, not shown), includes a register (41) whose last three stages are fed via resistors (R, 2R, 3R), to an adder feeding 1.p.f. (46) and v.c.o. (47). The generator cycle  may be shorter than each element period so that successive elements have a different time axis, or the cycle may be equal to each period with an artificially generated start-point for increased security.

Abstract: 1,027,222. Furnace walls. PILKINGTON BROS. Ltd., and J. R. BEATTIE. April 9, 1963 [May 3, 1962], No. 17082/62. Heading F4B. A heat treatment furnace for heating sheet glass and other purposes has cavity side walls 1 formed by spaced partitions 2 . . . 6, the innermost partitions being coated on at least one surface with a coating comprising a refractory material to establish a layer on that surface having a surface reflectivity greater than its surface absorptivity at the operating temperatures. The partitions 2 . . . 6 are held in spaced relation by refractory spacers 7 carried by rigid frames 8. The partitions 2 . . . 4 are made of refractory metallic material, partition 5 is of stainless steel and partition 6 of aluminium. The outer surface of partition 2 and the inner and outer surfaces of partitions 3, 4 have layers 9 . . . 13, preferably 0À005 inch thick, of zirconia which includes 5% by weight of calcium oxide, said layers being deposited as an atomized spray. These layers cause more heat to be reflected by the surface than is absorbed by the same, and cause heat to be redirected towards the interior of the furnace. Other refractory materials may be used provided their heat reflectivity is greater than their heat absorptivity at a substantial portion of the wavelengths below 6 microns. Heating elements 14 of nickel-chromium strip are supported by refractory bodies 15 on the innermost partition 2. Gas burners may be used instead. The base 16 and the roof 17 of the furnace are of refractory material. Slidable roof closing members 18 can be opened for lowering a glass sheet 19 into the furnace.

Patent GB-832719-A (GB)
Title: Shifting register with inductive intermediate storage
Inventor: ECKERT JOHN PRESPER
IPC: G11C19/04
Filed: 1957-05-30
Abstract: 832,719. Magnetic amplifiers. SPERRY RAND CORPORATION. May 30, 1957, No. 17149/57. Class 40 (9). [Also in Group XIX] In a shifting register, e.g. for computing apparatus, comprising cascade-connected magnetic core devices each including an input and an output winding, a source of regularly recurring pulses is coupled to one end of each output winding, and the other end of each output winding is coupled to the input of the next core device by means including two rectifiers and an inductance. The shifting register shown in Fig. 2 employs " complementing " magnetic core devices I, II, III ... which provide output signals so long as input signals are not applied. Each device comprises a core 20, 30, 40 . . . , of material having a substantially rectangular hysteresis loop; the core may be of various shapes, e.g. cup-shaped or toroidal, and may be of ferrite or comprise strips of magnetic tape. In the normal state of the register, core 20 is in the positive remanent condition and winding 21 presents a relatively low impedance to positive " power pulses," Fig. 3A, from 23; thus for each such pulse an output pulse, Fig. 3C, is obtained which causes current to flow through diode D2 and inductance L1. When the power pulse ceases, the inductance will act as a current source and will cause a reverse current flow, Fig. 3 D, through a diode D3 and input winding 32 on the next core 30, a blocking pulse, Fig. 3 B, from 25 preventing current flow in the input winding while a power pulse is being applied. The current in winding 32 drives core 30 to the negative remanent condition, so that the following power pulse at winding 31 is used up in driving the core back to its positive remanent condition and no appreciable output is obtained from device II. Thus core 40 receives no pulses at input winding 42 and therefore produces output pulses, Fig. 3G, in response to the power pulse at winding 41. Similarly, each odd core is in the output-producing state and each even core in the non-output-producing state. If an input pulse, Fig. 3H, is applied from 24 to input winding 22, it will shift the first core 20 to the negative condition. Thus, for the next power pulse, no output will be obtained to energize L1, Fig. 3D, and the following power pulse will produce an output from core 30 which energizes inductance L2, Figs. 3E and F. This in turn prevents an output pulse from core 40, Fig. 3G, and so on. Thus each pulse at 24 is shifted along the register as a series of changes from normal. Current in the first input winding 22 is blocked, during the application of power pulses, by a circuit comprising resistor R and diode D8. Reference is made to the use of " non-complementing " magnetic core devices.

[Class 135] [Also in Groups XXIV and XXII] In a machine such as a stamping press,. indicated at 1, which requires one or more operatives a number of hand starting and stopping valves are provided and arranged so that all the starting valves must be actuated simultaneously to start the machine to ensure that the hands of the operatives are clear of the working parts, whilst actuation of any of the stopping valves will stop the machine. Starting valves 60, 62, 64 and 66 in series with a compressed air supply 48 and a main starting valve 35 are arranged on the four corner posts 2 of a stamping press requiring four operatives. Stopping valves 81, 84, 85, 86 are provided one adjacent each of the starting valves and are arranged in parallel with the compressed air supply 48 and a main stopping valve 34. The valves 34 and 35 are similar and comprise pistons which are actuated by the compressed air from the hard starting or stopping valves to actuate valve members controlling the relief of pressure from either side of a piston distributing valve 6, shown in detail in Fig. 3, through conduits 47, 52. The piston valve member 15 controls the supply of compressed air from a conduit 50 to conduits 51 and 53 leading to the two sides of a power piston 4, Fig. 10, for actuating a clutch 3 of the machine. Leakage ports 30 and 31 are provided in the ends of the piston valve member 15 so that the air pressure can build up on the side of the piston which is closed to atmosphere and cause the valve to move to the side which is opened to atmosphere. A further stopping valve 87 similar to the valves 81, 84, 85, 86 may be provided for automatic stopping of the machine, by a part 96 of a cam 90 on the crank-shaft of the machine, after each cycle of operation. The cam 90 has also a safety portion 94 which maintains the stopping valve 87 open, and therefore requires the operatives to keep their hands on the starting valves, whilst the press is lowering so that the distributing valve remains in its " on " position. A further hand operated valve 101 is provided, in series with the cam actuated valve 87 and the main stopping valve 34, which is normally open but is adapted to be closed in the event of the press stopping with the valve 87 held open by the cam part 96 to allow another '' inching " valve 112 to be actuated to start the press to give the crank-shaft a slight rotation. A further stopping valve (not shown) may be provided to be actuated when the pressure of the compressed air supply falls below a predetermined value to exhaust the air from the stopping side of the distributing valve 6 to move it to effect the withdrawal of the clutch 3.
