Filed: 1964-10-22
Abstract: 1,061,805. Welding by pressure; brazing. INTERNATIONAL BUSINESS MACHINES CORPORATION. Oct. 22, 1964 [Nov. 19, 1963], No. 43042/64. Heading B3R. In bonding, e.g. resistance welding or brazing, a non-conductively coated member to another member, an electrode is energized to heat and fuse the coating whereupon current is passed through the electrode and the members to produce the bond. A machine for welding insulated wires 86, Fig. 1, to a terminal 87 has a block 17 adjustable vertically on rods 12 in a base 10 by a nut 20. A frame 24 adjustable transversely of and mounted in the block 17 carries a common pivotal mounting 31 for two slightly flexible rods 32, 33, respectively and adjustably supporting a U-shaped molybdenum or platinum rhodium alloy electrode 40 and a contact 45. A weight 35 is mounted on the rod 32. Actuation of a handle 58 operates a micro-switch 61 to energize a control circuit and rotates an eccentric stop 64 to allow springs 73 acting on the rods 32, 33 to engage the base of the U-shaped electrode 40 with a coated wire 86 and to lower the contact 45 until a pair of spring fingers at its end straddle and locate the wire 86 and engage the terminal 87. A control circuit discharges a capacitor through the electrode 40 which heats up and fuses the coating on the wire 86 and then discharges a capacitor between the electrode 40 and the contact 45 to weld the wire 86 to the terminal 87. After the electrode 40 has been raised a further capacitor discharge through the electrode 40 reheats the electrode 40 and cleans its surface. Alternatively A.C. may be used for the heating and welding currents. In a modification the contact 45 is replaced by a second U-shaped electrode which simultaneously serves to weld a second coated wire to the terminal.

Title: Leaching tio-containing slags
IPC: C22B34/12
Filed: 1964-10-26
Abstract: Titanium dioxide-bearing slag containing as an impurity at least one of the elements chromium or vanadium is leached with sulphuric acid containing ferric ions resulting in a titanium dioxide residue low in chromium and vanadium. Ferric ions can be introduced in various ways such as by pre-oxidation of the slag or by addition of oxidants such as air or an oxidizing chemical compound during leaching.  The ferric ions may also be introduced by mixing ilmenite with the slag or by using an acid solution containing ferric ions as, for example, by adding ferric sulphate or by using acid previously used for leaching ilmenite.  The slag and the ilmenite may be commonly ground so that about 90% by weight will pass a 325-mesh Tyler screen.  Sulphuric acid waste acids as from the manufacture of TiO2 pigments may be used, the strength of which may be increased by evaporation or fortification.  The acid strength may be from 15-60% and the temperature from 100 DEG  to 250 DEG  C. at pressures up to 500 p.s.i. The acid may be in, say 20%, excess.  Lower temperatures require longer times or higher acid concentrations.  For example at 200 DEG  C. using 30/40% sulphuric acid the appropriate time is two hours.

Title: Production of acetylene by thermal cracking of liquid hydro-carbons
Inventor: NONNENMACHER HELMUT
IPC: C07C11/24
Filed: 1961-12-06
Abstract: Acetylene is obtained by thermal cracking of liquid hydrocarbons in the presence of insufficient oxygen for complete combustion by reacting part of the liquid product containing carbon black with oxygen by burning in a free space and introducing into the combustion products lateral, penetrating jets first of hydrocarbon to be cracked in an amount of 1-3 kg. per cubic metre (S.T.P.) of oxygen and then, as quenching fluid, liquid product containing carbon black in an amount to reduce the temperature below 500 DEG C.  The flame direction is preferably upward and the reactor walls may be washed with liquid cracked product. The amount of liquid product, boiling above 85 DEG C., recycled to the burner may be 30-150% of the hydrocarbons to be cracked.  The process may be effected at 1-20 atmospheres, the combustion products being at 1200-2800 DEG C. before mixing with the hydrocarbon feed and 800-1600 DEG C. after.  Diluent gases, e.g. steam or carbon dioxide, may be introduced at any point as desired.  In an example, crude petroleum oil is cracked.

Filed: 1976-10-22
Abstract: 1537533 Fuel injection systems ROBERT BOSCH GmbH 22 Oct 1976 [24 Oct 1975] 43873/76 Heading F1B In a continuous injection fuel injection system for I.C. engines, a spool 14 of a metering and distributer valve 10 is moved during starting at low temperatures by a bi-metal spring 53, which is heated by an electric element 59 energized during starting to move the bi-metal spring 53 away from the spool 14. In Fig. 1, the bi-metal spring 53 is mounted on lever 11 pivoted together with lever 12 at point 13. Elements 59 and 62 are both energized during starting by way of ignition switch 60 and starting switch 61 and the bi-metal spring 53 bends to reduce the fuel supplied via valve 10. The right hand end of the bi-metal spring 53 may be mounted on the housing with its free end engaging the lever 11. In Fig. 2 (not shown), bimetal spring 66 is pivoted about point 67 by a solenoid 69 energized during starting. A pressure control valve 42 controls the richness of the air-fuel mixture during warming up. The restoring force on spool 14 provided by the pressure in chamber 39 is lower at lower temperatures because a bi-metal spring 49 then acts downwardly on spring 46 provided to bias diaphragm 45 towards seat 44. The bi-metal spring 49 is heated by an electrical element 50 after the engine is started with the result that the diaphragm 45 is biased more strongly towards seat 44 causing weakening of the air-fuel mixture.

Title: Multi-record graphic recorder
IPC: G01D1/12
Filed: 1963-11-07
Abstract: 1,018,832. Recording-apparatus. LEEDS & NORTHRUP CO. Nov. 7, 1963 [Nov. 23, 1962], No. 44046/63. Heading G1J. Apparatus for recording a plurality of different variables comprises a motor 13 for driving a pen 14 across a strip 15 a distance proportional to the value of a variable in response to signals derived from one of a number of transducers 8 (A to D) and a motor 16 for driving the strip 15 by an amount distinctive of the particular variable being recorded. The apparatus may be used for recording continuously from a transducer 8A by throwing a switch 9 to the right (a) to connect supply lines 20A, 20B to motor 16 which then drives the strip 15 at constant speed (b) to connect lines 20A, 20B to solenoid 17 to move the pen 14 into contact with the strip 15 and (c) to connect transducer 8A to network 11 to be balanced continuously by motor 13 so that the pen 14 records a curve A. For recording cyclically from transducers 8B, 8C and 8D the switches 7 and 9 are set as shown. A motor 19 drives a cam shaft so that cams 18 (A to C) successively close contacts 24 (A to C). In the position shown cam 18A has closed contacts 24A energizing relay 25A which closes contacts 29A, 34A. Contacts 29A connect transducer 8B to network 11 and motor 13 moves pen 14 across strip 15 in accordance with the value measured. Meanwhile a capacitor 27A in parallel with relay 25A has been charged so that when cam 18A opens contacts 24A and closes contacts 45A the capacitor 27A discharges through the relat 25A delaying its opening until current has passed through motor 16 and solenoid 17, causing a mark B to be traced during the discharge. Cams 18B and 18C similarly control recording from transducers 8C, 8D to produce marks C, D. By varying the delay interval of the capacitors 27 (A to C) the different lengths of the marks B, C, D can be used as distinguishing features. For example with a chart speed of three inches a minute delays of 5 sec., 1 sec. and 1.5 sec. produce marks 1/64", 1/32" and 3/64. For use in chromatography, transducer 8A represents the measuring cell, switch 7 is first placed in neutral position and switch 9 to the right so that curve A is traced and shows peaks occurring at times t 1 , t 2 , t 3 , t 4  .... attained by the components of the sample eluted. Then in order to monitor the variations in peak value, of the components having peaks at times t 1 , t 4 , t 6  the cams 18 (A to C) are set to turn switches 22 (A to C) on and off just before and just after times t 1 , t 4 , t 6 . Switch 9 is thrown to the left and switch 7 to the right so that the output of the measuring cell 8A is repeatedly applied to the network 11 for brief intervals embracing times t 1 , t 4 , t 6  to produce curves B, C, D for the three components selected.

Abstract: 1,077,567. Monopulse radar. CSF-COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. Oct. 25, 1965 [Nov. 9, 1964], No. 45153/65. Heading H4D. In an amplitude comparison monopulse radar, means are provided controlling the display of echoes from targets situated outside the angular region in which the main lobes of the two antennae overlap. Outside this region, a main lobe of one antenna will overlap an antiphase side lobe of the other antenna, with   the result that the difference signal ## is greater than the sum signal ##. Control is thus made on the basis of the value of the ratio |#/# D |.   Hybrid ring means 4 produces sum ## and   difference ## signals from the antennae outputs, and feeds them to a second hybrid ring 6, the   ## signal being fed via a 90 degree phase shifter   to give a signal j##. The ring 6 produces signals   equal to ## - j## and ## + j## and these are fed via limiting amplifiers to a phase detector 10. The output of the detector is proportional to Cos 2#, where 2# is the angle between the vectors ## + j## and ## - i##, and is positive for |#/# | < 1 and negative for the controlling mode of |#/#| >1. The output of the detector may control the display of a normal radar display 9   fed by the ## signals. A mathematical analysis is given showing how the invention operates when a plurality echo signals are received.
