Title: Blast furnace stove control
IPC: F23N5/00
Filed: 1970-10-26
Abstract: 1283790 Programmed control of flow JONES & LAUCHLIN STEEL CORP 26 Oct 1970 [10 Nov 1969] 50748/70 Heading G3N The flow of blast-furnace gas, natural gas and combustion air, for heating a stove for cyclically pre-heating air to a blast furnace is controlled in dependence on a predetermined programme relating the temperature of the dome of the stove to the time during which the gases are heating the stove. As shown, the flow-rate of furnace gas on a line 12 to a burner is regulated by a pneumatic valve 17, controlled electrically in response to the output of a transducer 10, measuring the difference in pressure across an orifice 11 through a squareroot determining device 13, by a proportional and reset controller 15. The supply of natural gas mixing with the furnace gas at a junction 42 is similarly regulated by a valve 41 operated by a controller 35, as is the supply of combustion air on a line 24 by a controller 20 and valve 26. The controller 15 is set for the desired furnace gas flow-rate by a device 14. The controller 35 is set by a temperature comparison circuit comprising a profile function generator 30 the output of which represents the desired dome temperature with respect to time. The output of the generator is compared with the dome temperature, as sensed by a device 31, by a controller 32 having an output proportional to the temperature difference which is fed to a potentiometer 33. The set output of potentiometer 33 is fed to the natural gas rate controller 15 through a device 34, which is responsive to the actual blast furnace gas flow-rate from device 13 to keep the desired natural gas flow-rate below a preselected percentage of the actual furnace gas flowrate.

Title: Hydrofoil system for longshore fishing and other underwater purposes
IPC: A01K73/05
Filed: 1965-12-02
Abstract: 1,131,856. Fishing apparatus. W. KING- STON. 1 Dec., 1966 [2 Dec., 1965], No. 51107/65. Heading A1A. [Also in Division B7] A fishing net is anchored by a device having two hydrofoil blades 1 supported by members 2 to slide in a frame 5 which includes two triangular guides 9. Net ropes 10 are slidingly connected to the guides by rings 11, and cables 12, 13 also connect the blades 1 to the guides and are arranged so that when the net rope ring 11 slides to one side of the triangular guide 9, as shown, it pulls on the cable 13 to tilt the hydrofoil blades whereby spikes 6 are pushed downwardly into the bed. On a change of flow (change of tide) the ropes slide to the other side of the triangle and pull on the other rope 12 to tilt the blades in the opposite direction. For lifting a net, the hydrofoil shown in Fig. 2 is connected to a net rope 10 and its tilt and therefore the amount of lift exerted is adjustable by an attachment cable 20 whose securing position to the hydrofoil is adjustable by a screw arrangement 17 to 19. The blades are formed with metal skins and a main spar of metal, paper or plastics honeycomb surrounded by a foamed polyurethane plastic. A catch which is released on striking the ground, can be used to hold the hydrofoil blades in a position for generating maximum force when the anchor is being dropped.

Title: Semiconductor integrated circuits
IPC: H01L21/86
Filed: 1971-11-11
Abstract: 1369449 Transistor bi-stable circuits PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 11 Nov 1971 [14 Nov 1970] 52406/71 Heading H3T [Also in Division H1] In a monolithic logic circuit the collector of a multi-emitter transistor acting as a gate is connected direct or through further circuitry to the base of a further transistor of like conductivity type. The two transistors are formed in PN junction isolated sections of a surface layer of opposite type to the underlying substrate over buried inclusions of the same type as the layer, the base region of the multi-emitter transistor being formed in the same diffusion as the isolation region and thus extending to the underlying inclusion whereas that of the further transistor is formed independently and is spaced from the associated buried inclusion. This results in the former transistor having the desired lower inverse current amplification factor, which may be further reduced by increasing the emittercollector spacing at the wafer face. In integrating the Fig. 1 circuit in the form shown in Fig. 3 arsenic is first diffused into an oxidemasked P type silicon wafer to form the buried inclusions beneath each section to be isolated prior to deposition of the N type epitaxial layer. In the next step boron is diffused through reformed masking to form the isolation network 4, the base zones of multi-emitter transistors T 5 , T 6  and the emitters and collectors of the lateral ring-dot PNP transistors T 7 -T 10 , which, when terminals B and C are resistively connected, constitute with similar diode-connected transistor, T 11  two current sources. In a subsequent shorter diffusion the shallow base regions 10 of the pairs of cross-coupled transistors T 1 -T 4  are formed, and in a final phosphorus diffusion the emitters of all the NPN transistors and N type base and collector contact regions are provided. The masking oxide is retained or replaced by silicon oxide/nitride and aluminium vapourdeposited overall and pattern etched to form the circuit connections. Alternative materials are germanium and A III B VV  compounds for the wafer and molybdenum, gold and multiple layers for the metallization.

Filed: 1969-10-28
Abstract: 1280879 Antiskid braking systems NORTH AMERICAN ROCKWELL CORP 28 Oct 1969 52657/69 Heading F2F A vehicle fluid pressure braking system intended to permit full braking pressure to be developed at the vehicle front wheels but to maintain the braking effort at the rear wheels at a level just below that which will establish wheel lock except when the front wheels lock has a normally open valve 87, interposed between the pressure source and the rear brakes, which is closed by means responsive to a predetermined decrease in velocity of the rear wheels relative to that of the front wheels and a bleed valve 90 interposed between the normally open valve 87 and the rear brakes controlled by means responsive to a second greater decrease in said rear velocity relative to the front wheel velocity to further reduce the braking pressure. The wheels 10-12, 14, 16 are equipped respectively with conventional air brake mechanisms 18, 20, 22, 24 receiving compressed air from a reservoir 32, charged by an engine driven compressor 26, via a drivers valve 34. Each vehicle wheel has a mechanism including a transducer 58a, 58b, 58c or 58d which generates a signal indicative of the rotational velocity of the wheel and the signals -are passed to rectifier and filter networks 60, 62, 68, 69, the combined output signal of the front wheel transducers being fed to differential comparators 72, 78 and the combined rear wheel output being fed to comparator 72 through a variable attenuator 79 and to comparator 78 via a variable attenuator 80 so that as the voltage varies across the terminals 72A, 72B of comparator 72 due to the velocity of the rear wheels being less and thus approaching a lock-up condition, the output triggers an amplifier 85 to operate valve 87 and when a further decrease of velocity occurs an amplifier 88 is triggered to operate valve 90 and release the brake pressure. A by-pass conduit with check valve 116 facilitates quick release of the brakes. When the front wheels are locked valves 87, 90 will be open thus permitting full braking pressure on the rear wheels.

Abstract: 1320968 Feed pumps J HœBNER 12 Nov 1970 [19 Nov 1969] 53783/70 Heading F1A A feed pump, especially for viscous media, comprises a cylinder 1 in which reciprocates a piston 5 with a reduced diameter portion 7 which co-operates with an enlarged diameter portion of cylinder 1 to form an annular space. A foil 14 is attached to portion 7 and has its periphery clamped between parts 2, 3 of cylinder 1. Polyamide washers are inserted in the annular space and engage the foil 14 to restrict flexing thereof. Piston 5 has a spring-biased shaft 6, the end of which receives a pivot bearing 28 of a lever having arms 27, 30. Oscillations of arm 27 are transmitted to piston 5 via bearing 28 due to a counter abutment 31 on arm 30. Abutment 31 is supported by a slider 34 which is moved parallel to the lever under the control of a spring-biased bolt 37 opposing a control piston 35 which reciprocates in a cylinder 39 connected to the outlet 25 of the pump. Thus if pressure in the line 25 increases the piston 35 moves abutment 31 to the right thus reducing the stroke of piston 5. If a spray gun attached to line 25 is closed, the resulting pressure causes the abutment 31 to assume the clotted position in Fig.1 above bearing 28 so that no motion is transmitted to the piston 5. Washers 16 can be replaced by ring segments, Figs. 2, 3 (not shown) and piston 35 can be covered by a flexible cap so as to separate it from the viscous medium, Figs.4, 5 (not shown).

Abstract: 542,380. Catalytic hydrogenation. DU PONT DE NEMOURS & CO., E. I. June 4, 1940, No. 9754. Convention date, June 6, 1939. [Class 1 (i)] [Also in Group IV] Ethers of polyhydric alcohols are made by hydrogenation' of aldehydes of the formulae where R is alkyl, aryl, aralkyl, alkoxymethyl or aryloxymethyl and the R groups may be similar or dissimilar when two are present. Preferably the hydrogenation is effected under pressure with a hydrogenation catalyst and if desired in the presence of an oxygen containing solvent such as an alcohol, ether or ester. The hydrogenation catalyst may contain a metal oxide promoter, and may be a metal or metal oxide containing a more acidic oxide such as copper chromite. When the initial aldehyde is prepared from formaldehyde and contains some of that body, it is preferred to effect the reactions at pH7.5-9. In examples (1) glycerol-#-methylether is obtained by hydrogenating glyceric aldehyde α-methyl ether in the presence of methanol and sodium hydroxide at 80-120‹C. and 600 atmospheres pressure, (2) glycerol-#- methoxy-methyl ether is prepared from glyceric aldehyde α-methoxy-methyl ether, using a nickel oxide on kieselguhr catalyst ; (3) erythritol-1-3- dimethyl ether is made from 2-hydroxy-1-3 butyraldehyde.
