Title: Improvements in plated metal wire-like material
IPC: B21C47/26
Filed: 1948-02-02
Abstract: 663,044. Wire; making compound wire. KENMORE METALS CORPORATION. Feb. 2, 1948 [Feb. 1, 1947; June 26, 1947], Nos. 3042/48 and 3043/48. Class 83 (ii). [Also in Group XXXVI] A rod-like element has a metal core and twenty to seventy-five layers of metal concentrically plated thereon, the layers being separated from each other by layers of weakness which permit. the metal layers to slip with respect to one another when subject to forces of extension. In the arrangement shown diagrammatically, a stiff wire 12 in helical form is passed through a number of baths including an electro-plating bath 33 in which the wire is immersed several times. As the wire is exposed between each immersion a thin coating of oxide is formed, constituting a layer of weakness. The wire is fed through the baths by means of a rotating shaft with which the wire is maintained in contact by a roller 15. Products of the invention include a steel or copper wire coated with nickel, a base metal alloy containing iron and nickel, which is coated with copper, and a metal core with a plating of nickel chromium alloy, zinc, cadmium, or tin. The plated wire may be drawn to desired size and then flattened. Specifications 601,994, [Group XXXVI], and 645,834 are referred to. Reference has been directed by the Comptroller to Specifications 9011/01 and 231,997, [both in Class 41].

Abstract: 487,257. Thermionic valves. M-O VALVE CO., Ltd., and SMITHELLS, C. J. Feb. 2, 1937, No. 3064.

Title: Method of decontaminating aqueous solutions of nitrites of alkali metals and/or alkaline earth metals
IPC: C02F1/70
Filed: 1963-01-24
Abstract: Alkali metal and/or alkaline earth metal nitriles are removed from aqueous solutions, particularly industrial waste solutions, by adding to the solution in the presence of excess acid ions a decontaminating agent consisting of (a) sufficient mineral acid to convert the total metallic nitrite to nitrous acid and (b) sufficient of compound RNH2, where R is H or an organic radical, to convert all the nitrous acid to free nitrogen, or consisting of a salt of the reaction (a) with (b), the pH of the solution being used as a retro-active control of the supply of the decontaminating agent; the latter may be ammonium chloride or preferably hydrochloric acid plus urea, which mixture when used in a ratio 2: 1 to 3: 1 provides also the required excess acid ions. The reaction produces nitrogen, and a nitrite-free solution which may be discarded into public drainage.

Title: Improvements in braking systems for steerable vehicles
IPC: B60T13/12
Filed: 1926-02-04
Abstract: 270,383. Edwards, C. K., and Associated Equipme,nt Co., Ltd. Feb. 4, 1926. Braking; hydraulic and pneumatic transmission. -Fluid-pressure operated steering-wheel brakes are provided with brake-releasing devices, one for each wheel, which are so controlled by the position of the steering road wheels that when the vehicle is rounding a curve the brake on the outer wheel is released. The brake-releasing device may be arranged so that first it isolates the corresponding brake and subsequently releases it. In the construction shown in Fig. 1, the stationary steering-point 14 carries a cam 16 the raised part 18 of which is adapted to be engaged by the plunger 23 of a valve casing 20 which is carried by and swivels with the stub axle 13. Air is admitted from a source of supply through a pipe 21 to the valve casing 20 and passes through a valve 25 and pipe 22 to the corresponding steering wheel brake. When the vehicle is steered each valve plunger 23 moves over its cam, the plunger on the inner wheel passing idly over the low part 17 of its cam, while the plunger on the outer wheel engages with the raised part 18 of the corresponding cam and'so actuates a double valve 25, 27. The first action of the plunger is to compress a spring 29 and raise a valve stem 24, thus closing the valve 25 and isolating the pipe 22 and its braking means from the other brakes. Further movement of the plunger 23 causes it to lift the valve 27 and' allow the air to escape from, the brake pipe 22 past the valve 27 to the atmosphere through a port 30. A single valve may be used instead of the double valve 25, 27. In the construction shown in Fig. 3 a cam 31 on the rocker-shaft of the steering gear acts either on a valve 35 controlling the brake on one steering-wheel or on a valve 36 controlling the other steering wheel brake. According to the Provisional Specification, the brakes on more than one steering-wheel may be released when the steering-gear is operated.

Title: Improvements in means for producing a variable voltage
Inventor: GURWICZ DAVID
IPC: H03K5/01
Filed: 1967-01-21
Abstract: 1,215,296. Converting. SEVCON ENG. Ltd. 6 Dec., 1967 [21 Jan., 1967], No. 3244/67. Heading H2F. [Also in Division G1] A direct voltage is produced at output terminals OP of a magnitude dependent on the position of a movable ferrite core of an inductance L1. A multivibrator TR1, TR2 generates a sawtooth wave which causes a linear ramp variation of current through TR3. This induces in the inductance L1 a constant voltage which is stored and smoothed (D1, R1, C1) and fed to the output terminals OP by the double emitter-follower TR4, TR5. The energy in the inductance at the end of the sawtooth is absorbed by R2 and D2, and a Zener diode ZX1 provides a backing voltage so that the output can be set to zero by adjustment of VR1 when the inductance L1 has its minimum value. The output voltage OP may be used to control a variable frequency or variable pulse width oscillator controlling the speed of an electric motor, e.g. in a battery operated vehicle, or the system may operate as a transducer, in connection with flow rates, pressures or like situations in which an electrical potential corresponding to a movement is required.

[Class 80 (i).] A driving-belt for use with expanding pulleys with twin-coned flanges comprises a flexible flat chain a, Figs. 1 and 4, to take the tension, and transverse blocks or tread members b to take the squeezing effect of the pulley and prevent such squeezing acting on any part of the chain. The blocks b are shown as solid members straddling'the chain and carrying friction tread surfaces 2 for engaging the pulley flanges. Each block b is fitted to the chain a by eye-bolts d threaded on a cross pin g which couples together parallel links of the flat chain. The bolts d pass through the block b and are secured by nuts f. In a modification shown in Figs. 7 and 9, the tread blocks b are built up solid with a row of parallel links 12 of the chain and clamped by through bolts 14 in such a way that the squeezing of the pulley flanges does not interfere with the free flexure of the belt as a whole. Reference has been directed by the Comptroller to Specification 30014/13, (Class 80 (i), Gearing, Belt &c.].

[Class 29] Absorption systems.-In a boiler for continuous cycle inert gas systems of the kind having a heated pump tube 19, a liquid heat exchanger 11, a vertical conduit 15 containing an unbroken liquid column forming the reaction lead for the pump and communicating freely with an absorber vessel 14, and a second vertical conduit 17 from which weak liquor is passed to the absorber by a pipe 18, the pump tube 19 is heated within a zone located between the liquid level in the conduit 15 and the lowest point of the heat exchanger 11. The boiler conduit 15 is welded to the flue tube 10 and com-- municates at its lower end with the pump tube 19 also welded to the flue so that weak liquor is pumped into the tube 17 which, through the outer tube of the liquid heat exchanger, communicates by the pipe 18 with the absorber. Strong liquor from the absorber passes by a pipe 13 and the inner tube 12 of the liquid heat exchanger to the boiler conduit 15. The upper end of the conduit 17 opens into the vapour pipe 16 and the conduit 17 may also be in heat conductive relation to the flue tube. The pump tube is welded to the flue tube 10 between the points 20 and 21. In a modification an auxiliary boiler is provided comprising a tube connected to the boiler- 15 at a point slightly below the liquid level and connected at its lower end to the pump tube 19. Fig. 3 shows the boiler conduit spaced from the flue tube 10 at its lower part 22 to ensure sufficient heating of the pump tube at this part. This spacing may be provided by bending the boiler tube as shown or by suitable arrangement of the welding material between the upper parts of the boiler and flue tubes. The conduit 17 may form the boiler conduit.
