Patent GB-1534230-A (GB)
Title: Data processing apparatus
IPC: H03M7/00
Filed: 1977-10-05
Abstract: 1534230 Shift networks INTERNATIONAL BUSINESS MACHINES CORP 5 Oct 1977 [11 Nov 1976] 41371/77 Heading G4A The shift operations necessary to perform conversions between packed and zoned decimal formats are effected by a routing network which operates in parallel by byte instead of serially by byte as in prior art processors. The routing network is combined with a 0-7 bit shifter in a two-stage network which can perform normal shift operations required in a processor as well as the format conversions. The preferred embodiment of network is formed from integrated circuit chips each of which routes, from each byte, a corresponding bit from the high and low order halves; for example, Fig. 12 shows the chip which handles bit 3 and bit 7 from every byte. This arrangement reduces the number of inter-chip connections which would otherwise benecessary because of the high order-low order cross-overs which occur in the format conversion when the zone codes are inserted or eliminated. Each chip receives a shift amount 47 which is decoded to provide shift control signals R0D-R4 for first and second level byte shifters 50, 53 and 52, 55. The first level normally shifts by between 0 and 3 bytes and the second level by 0 or 4 bytes, a total shift of 8 bytes being performed in the unpack (packedzoned) conversion without sign operation. The second level is also controlled by a control decoder 58 to perform the format conversion shifts which increase/decrease progressively for successive bytes. Fig. 17 shows an example for a zone to packed format conversion for bits 3 and 7 of bytes 0-7. For the reverse conversion, the cross-over is in the reverse direction and 1's are forced in the bit 3 positions of all bytes except that containing the sign digit (byte 6), (the zone code being 1111). An additional chip is provided for handling the byte parity bits.

Title: A photo-electric cathode and method for its manufacture
IPC: H01J1/34
Filed: 1963-10-23
Abstract: A photo-cathode, Fig. 1, comprises a glass surface 1 having a first layer 2 thereon which comprises slightly oxidized tungsten, molybdenum, manganese, chromium or cobalt and a second layer 4 on the first layer comprising antimony and a plurality of alkali metals. Alkali metals mentioned include potassium, sodium and caesium.  An image intensifying tube temporarily provided with means for depositing the two layers of the photo-cathode is shown in Fig. 2. Inside a glass envelope 10 are electrodes 11, 12, 13, a fluorescent screen 14 and a disc 15 to cover the aperture in electrode 12 while the photo-cathode is being formed.  The photo-cathode 23 is formed by evaporating on the glass envelope 10 a first layer of tungsten from a tungsten filament 18 fixed to two rigid conductors 19 connected by sliding contacts 20 to terminals 21 in a glass tube 16, including soft steel parts 22 so that filament 18 may be moved along tube 16 by an external magnet (not shown).  In one method, envelope 10 is evacuated through tube 17 to a pressure between 5.10-3 and 5.10-5 Torr, filament 18 is moved to a central position and heated by passing current through it which causes the tungsten to evaporate. During this operation a small portion of the tungsten layer oxidizes. In a second method, the tungsten is evaporated with an air pressure below 10-6 Torr.  After deposition of the layer, the tungsten is partially oxidized by admitting oxygen into the envelope until the pressure is from 10-3 to 10-4 Torr, and releasing an electrical discharge between one of terminals 21 and terminal 24 connected to layer 23.  Filament 18 is then withdrawn from the envelope and the vacuum increased to 10-6 Torr.  The second layer is then deposited by evaporation of successive layers of antimony from antimony rod 26, potassium from evaporator 27 at an envelope temperature of 160-200 DEG C., sodium from evaporator 28, and caesium from evaporator <PICT:0981480/C6-C7/1> <PICT:0981480/C6-C7/2> 29, the temperature for the evaporation of caesium being 140-160  DEG C.

Abstract: 1,075,731. Delivering measured quantities of liquid. D. V. ZIVANOVICH and V. AVRAMOVIC. Nov. 8, 1963 [Nov. 9, 1962], No.42505/62. Heading B8N. An apparatus for dispensing a measured quantity of liquid to a receptacle, such as disinfectant to a lavatory bowl (2) Fig. 1 (not shown) comprises a container 5 for the liquid 6, and a metering device (8) having an inlet 9 and an outlet 10 adapted to draw liquid from the container and to discharge a metered amount of liquid under pressure through the outlet and a discharge pipe (11). The metering device comprises a piston 17 slidable within a cylinder 15, the limits of movement being determined by stops 19, 21 on the piston rod 18. A compression spring is mounted between the stop 21 and the end-wall 20 of the cylinder so that after the rod has been pulled outwardly by a handle 22 to draw in liquid, via a non-return valve 27, the liquid is forced, via a non-return valve 29, through the outlet under the action of the spring; alternatively, a tension spring may be fitted between the rod 18 and the wall 20 so that upon pressing the piston inwardly to dispense the liquid, the spring is tensioned so as to return the piston and thereby draw in liquid in readiness for the next operation. The discharge pipe (11) leads into the lavatory bowl (2) and may be fitted with a spray nozzle (12); alternatively, the pipe may enter directly into the flush pipe 4. In modifications, the spray nozzle may dispense a measured quantity of liquid on to a felt or sponge pad so that the latter absorbs the liquid and allows evaporation thereof or the pad may be directly impregnated with liquid and the metering device actuated without liquid merely to force air through the pad. The container 5 may be of a synthetic plastic material, such as polyethylene.

[Also in Division G3] A protective arrangement for a power supply unit having a series voltage regulator St comprises a resistor R 1  in series with the regulator. A trigger circuit T 1 , T 2  which is caused to change its state by the potential arising across the resistor R 1  when the load current is excessive, and a resistor/capacitor network to provide a delay before the trigger circuit switches back to its original state. In the arrangement shown, the transistors T 1 , T 2  are respectively conducting and non-conducting so that the voltage at a point B is such as to render a control transistor T 3  non-conducting and a transistor T 4  conducting, an indicating lamp L being lit. When overload occurs, the voltage across the resistor R 1  biases the transistor T 1  to non-conduction so that the transistor T 2  conducts causing the point B to become more positive This causes the transistor T 3  to conduct and through a control device S cause the regulator Sk to switch off the supply. The transistor T 4  ceases to conduct and the lamp L is extinguished. A capacitor C is charged by the voltage across the resistor R 1  and on the interruption of the supply, discharges through a diode D 1  and resistors R 11 .....R 15  to maintain the transistor T 1  in its non-conductive state for a predetermined time, after which the transistor T 1  conducts and the supply is restored.

Title: Cracking of hydrocarbons
Inventor: FREY OTTO
IPC: C10G9/38
Filed: 1960-12-20
Abstract: In the cracking of liquid and/or gaseous hydrocarbons in the presence of fluidized granular inert or carbonaceous solids at 650-850 DEG  C. to produce gaseous olefins, e.g. ethylene, the effluent containing entrained solid is passed through a cyclone to remove the bulk of such solid and is then contacted with a hydrocarbon oil boiling above 250 DEG  C. which is a recycled portion of the product and which quenches the effluent and thereby vaporizing the lower boiling fraction of the recycled oil and removes the remaining entrained solid in the unvaporized higher boiling fraction, such solid is at least partly removed from the quenching oil and the oil is recycled to the fluidized bed reactor. Oxygen and/or steam may be added to the reaction, and pressures of 1.2-1.5 atmospheres are preferred.  The solid used is oil coke, ceramic, corundum, sillimanite or sand.  The process removes fine-grained solids from the reactor and thereby maintains at least 50%, preferably 70-95%, of the solid within the desired grain size of 100-3000 microns.  The quenching oil preferably boils in the range 350-650 DEG C. and, in quenching, a lower boiling oil may be added to assist cooling by evaporation. Solids are removed from the oil by centrifuging to separate 30-100% before recycle.
