Patent GB-1177904-A (GB)
Title: Dual Hydrostatic Transmission System with Power-Proportioning Control
IPC: E02F9/22
Filed: 1968-06-27
Abstract: 1,177,904. Hydrostatic transmission. GENERAL SIGNAL CORP. 27 June, 1968 [15 Nov., 1967], No. 30697/68. Heading F2D. A drive from two engines 11, lid, e.g. in a dual-engine scraper, to a common load 12, includes two hydrostatic transmissions 13, 13d, each including a variable displacement pump 14, (14a), and a motor 15, (15a), in closed circuit, the pump 14 being adjusted manually, and the pump 14a being adjusted automatically by a valve 33 responsive to main line pressures in the two closed circuits to maintain these pressures in a predetermined ratio, e.g. equal, to ensure a fixed ratio between the power delivery from each motor 15, 15a. As shown, the motors share the load equally, and the pumps are reversible. On increasing the displacement of pump 14, pressure in the main line, e.g. 16, increases and acts on a valve 23 in a pressure relief circuit 22 to connect the line 16 to an hydraulic actuator 36 acting on one end of a valve 33 which, directs pressure fluid from an engine-driven make-up pump 21a to one-side or the other of a piston 29 to increase the disi. placement of pump 18a.. Subsequent increased pressure in line 16a acts on. the end of. a valve 23a in pressure relief circuit 22a and is conneeted through that valveto an hydraulic actuator 37 acting on the end of valve 33. When the pressures in lines 16, 16a are substantially equal, the valve 33 is centralized, and the pump 14a is locked in its new position. On reversing pump 14, pressure in line 17 acts on actuator 36, and on the end of a reversing valve 38 for the pump 14a. By making the effective areas of actuators 36, 37, unequal, and/or by making the motors 15, 15a of different displacements, the ratio of share loading may be of any desired value. Again, Fig. 1 (not shown), pump 14a is not reversible, and pump 14 acts alone in reverse. Lines 16, 16a are connected directly to actuators 36, 37 respectively, and the reversing valve 38 is omitted. A by-pass valve (27) is inserted between lines 16a, 17a, and is opened whenever line 17 is pressurized, i.e. whenever pump 14 is reversed.

Title: Improvements relating to the filling of reservoirs with liquefied gas
IPC: F17C13/04
Filed: 1960-09-07
Abstract: 967,437. Smoker's lighters. NATIONALE S.A., and RONSON CORPORATION. Sept. 7, 1960 [Sept. 8, 1959], No. 30877/60. Heading F4F. The liquefied gas reservoir 1 of a smoker's lighter has a single orifice 4 for the simultaneous entry of liquefied gas from a refill vessel and the exhaust to atmosphere of gas in the reservoir, the orifice 4 being closed by a valve 6 adapted to be opened by a spout 12 on the refill vessel. The liquefied gas flows down a bore 26 and along grooves 27 in the spout 12 and then through lateral ports 10 in the cylindrical casing of the valve 6, and the gas in the reservoir escapes through the ports 10 and through the space between the spout 12 and the orifice 4. The refill vessel has a closure valve comprising a flexible resilient membrane 13 co-operating with a cylindrical valve seat 22. When the spout 12 is inserted into the orifice 4 of the reservoir and pushed downwardly it opens the valve 6 and the opening movement is stopped by the valve 6 abutting a projection 11 on a plug 9. Increased force on the refill vessel then causes the spout 12 to slide upwardly in the refill vessel to raise the membrane 13 so that liquefied gas can flow through holes 14 in the membrane 13 and through notches 29 at the upper end of the spout into the bore of the spout. In a modification, Fig. 3 (not shown), the reservoir valve comprises a strip of flexible material held at its two ends but having free sides. The enlarged central portion of the valve engages the orifice 4. The opening movement of the valve is limited by a shoulder on the spout engaging the valve casing. The spout has a longitudinal rib engaging in a groove 35 in the valve casing to insure that a transverse fuel groove on the end of the spout is directed towards the free sides of the valve.

IPC: H02M7/06
Filed: 1934-10-30
Abstract: 431,898. Rectifying alternating currents ; transformers; automatic regulation. WESTINGHOUSE BRAKE & SAXBY SIGNAL CO., Ltd., 82, York Road, King's Cross, London.-(Assignees of Gilson, R. M.; 615, Kirkland Street, Pittsburg, U.S.A.) Oct. 30, 1934, No. 31124. Convention date, Dec. 30, 1933. [Classes 38 (ii) and 38 (iv)] The output of a rectifier R supplying a load, i.e. a track signal TR is automatically regulated by means of a transformer T having a variably saturated shunt path 8, 9 to the core, the main windings being arranged on the limbs 10, 11. In series in the load circuit is a saturating winding 22, 23 arranged on the cores 8, 9 so as to be non-inductive with respect to the main windings. As the load current increases the saturation of the shunt increases and the voltage applied to the rectifier is increased. A battery B, for maintaining the supply in the event of the failure of the main supply, is connected in parallel with the rectifier R through a further saturating winding 29, 30 which is connected so that if current flows from the rectifier to the battery the rectifier voltage is reduced and if current flows from the battery to the load the rectifier voltage is increased. In a modification in which a secondary battery is used provision is made for maintaining a trickle charge. A further saturating winding is provided connected across the battery through a resistance which, if the battery voltage is normal neutralizes the effect of the winding 29, 30.

Title: New anthraquinone dyestuffs and the application thereof
IPC: H04R17/00
Filed: 1931-11-13
Abstract: Anthraquinone dyes are prepared by reacting an amino-3-keto-2,3-dihydrobenz-1,4-thiazine with a 1-hydroxyanthraquinone or a leucoderivative thereof, oxidizing, if necessary, and hydrolysing the product to give the substituted thioglycollic acid of which it is the lactam.  The 1-hydroxyanthraquinones may carry substituents and may comprise those specified in Specifications 4961/95 and 7538/96, [both in Class 2, Acids and salts, Organic &c.]; they are condensed with the amino-thiazine derivatives by the methods disclosed in these Specifications, the presence of pyridine or dimethylaniline as a diluent being mentioned.  In examples (1) leuco-quinizarin is condensed with 7-amino-3-keto-2,3-dihydrobenz-1,4-thiazine in pyridine and in presence of boric acid; saponification by means of aqueous caustic soda yields the thioglycollic acid which dyes wool green shades; the latter on treatment with hot dilute hydrochloric acid are "lactamized" to dyeings fast to potting; (2) the 7-amino derivative may be replaced by the 6-amino or 8-amino-6-methyl-derivatives of 3-keto-2,3-dihydrobenz-1,4-thiazines to give similar products dyeing green shades which may be "lactamized" on the fibre and remained fast to potting; (3) leuco-1,4,5-trihydroxyanthraquinone is similarly condensed with 7-amino-3-keto-2,3-dihydrobenz-1,4-thiazine; the dyeing shade after lactamization is green.  The above 6- and 7-aminothiazine derivatives are prepared by first hydrolysing (alkaline) the 5- or 6-aminobenzthiazole according to the process of Specification 355,808, treating the resulting mercaptophenylenediamines with chloracetic acid and ring-closing by means of hot dilute mineral acid. 8-amino-6-methyl-3-keto-2,3-dihydrobenz-1,4-thiazine is prepared by treating 4-chloro-3,5-dinitrotoluene with alcoholic sodium hydrosulphide to give the mercaptan which is then condensed with sodium chloracetate and reduced with zinc and acetic acid.

Title: Improvements in spirometer apparatus
IPC: A61B5/095
Filed: 1947-11-27
Abstract: 637,482. Respiratory appliances. FLEISCH, A. Nov. 27, 1947, No. 31475. Convention date, Dec. 10, 1946. [Class 81(ii)] A spirometer of the gasometer type is sub-divided into two compartments, one connected to the face mask and the outlet of a circulating pump and the other to the mask and inlet of the pump. In one embodiment the bell G, counter-balanced by a weight Gg, has a partition Q dividing it into equal chambers A, E. A pump P circulates air through a carbon dioxide absorber Ab. This arrangement permits the pump to supply air at half the breathing rate of the patient. Thus if the patient Vp breathes in at 4 litres/sec. while the pump supplies at 2 litres/sec. the additional 2 litres are taken from the chamber E. At the same time the pump withdraws 2 litres from the space A, which counterbalances the reduction in volume of space E, and the bell falls evenly. During the expiratory period 2 litres pass into the space A and 2 litres go to the pump while the pump supplies 2 litres to space E. The volume of oxygen absorbed is indicated by the fall in average height of the bell G. If any difference in pressure in the two chambers A, E might result in tilting of the bell G this may be overcome by having the chamber A of slightly greater volume or by mounting the bell to rise and fall about a horizontal pivot. In a modification by means of which oxygen is gradually added to the system, an additional bell containing oxygen is teed into the pipe between the pump and absorber and, by suitable control cocks, part of the air from the pump is made to pass through this bell. More even distribution of the enriched air throughout the system, and in particular, in the chambers A, E is obtained by passing all inhaled air through the chamber E and having a small orifice in the separating partition Q, see Fig. 4 (not shown).
