Abstract: 500,639. Metal tubes pressure gas cylinders. BERCOVITZ, B., and DEBOR, H. May 4, 1937, No. 12698. Void. Convention date, Nov. 11, 1936. [Classes 8 (ii) and 99 (ii)] [Also in Groups XXII, X, and XXI] Tubular steel for use as structural elements, for sustaining high internal pressure, for barrels for firearms &c., have the wall thicker in some places than others, particularly in the form of annular internal or external projections which may be worked into flanges, ribs or other forms. The manufacture may be effected by rolling, hammering, forging, pressinng, drawing, &c. A tube as show, Fig. 1. may be rolled on a mandrel, Fig. 2, divided for removal in sections, or the tube may be formed by hammering between swages. In a modification, Fig. 6, the extra metal f almost closes the tube. In a further modification, the metal is in the form of projections h, Fig. 7, and in a further modification, the annular projections extend both inwards and outwards. The elements may be used in the construction of motor cars and aircraft.

Title: Improvements in and relating to synchronous motors
IPC: H02K19/10
Filed: 1929-04-24
Abstract: 310,381. British Thomson-Houston Co., Ltd., (Assignees of Umansky, L. A.). April 24, 19218, [Convention date]. Driving - arrangements. - To vary the speed of running of a synchronous motor according to variations of load, the field member as well as the armature member is mounted for rotation and is used to drive a dvnamo-electric machine which transmits variable mechanical or electrical energy to the synchronous motor. In the arrangement shown in Fig. 1, the field member 13 of the synchronous motor 10 reversely drives a direct-current generator 16 feeding a motor 20 coupled to the armature shaft of the synchronous motor, which also has a flywheel 14. The generator 16 has an adjustable separately-excited field winding 25 and a differential series field winding 24, the strength of the fields determining the action of the set as a regulator of speed and torque. In a modified arrangement, the fields of the machines 16, 20 are reversible in order that they may interchange functions for the purpose of driving the field member 13 in the same direction as the armature 10, and thus obtaining regulated drive above synchronous speed. In the arrangement shown in Fig 3, the rotatable field member 52 drives an induction machine 53 which may work as a generator to transmit electrical energy to the line, or as a motor in the opposite direction. Specifications 225,564 and 271,084 are referred to.

Title: Improvements in gearing
IPC: F16H1/22
Filed: 1958-04-23
Abstract: 886,762. Toothed gearing; securing gearwheels to shafts. WALLGREN, A. G. F. April 23, 1958, No. 12873/58. Classes 80 (1) and 80 (2). In order to equalize the load transmitted by two intermediate shafts 30, 31 in helical reduction gearing between shafts 14, 24, both the intermediate shafts and one or other of the driving and driven shafts, or the gear thereon, is free to move axially and each of the two parts 20 or 22 of a double helical pinion on the driving shaft 14 is engaged by a single helical gear 36 or 44 on the respective intermediate shaft. The two intermediate shafts also carry double helical pinions 48-50 engaging a double helical gear 54 on the driven shaft 24. The shaft 24 is held against axial movement by a thrustbearing 26, the shafts 30, 31 being free to move axially to equalize the load taken by the two pinion parts 48, 50. The gear casing includes a partition 12 serving to support the intermediate and driven shafts, the single helical gears 36, 44 being on overhanging end portions of their shafts. The double helical pinion 20-22 and its co-operating gears have a small tooth angleless than half that of the gear 54- in order to reduce the axial forces in the gearing. The pinion 20-22 comprises two single helical pinions of opposite hand which instead of being keyed to the shaft 14 have end-face clutch couplings with each other and with a sleeve keyed to the shaft. The shaft 14 is supported by a bearing in the partition 12. The two sets of teeth of the pinion 20-22 may have slightly different inclinations so as to produce an axial force on the shaft 24 which will prevent any tendency for play in the bearing 26, or may have different tooth numbers so that the gears on the shafts 30, 31 are not identical. The driving and driven shafts 14 may be coaxial or may be slightly eccentric, the gear pairs 20-36 and 22-44 then differing. The gear-wheels may be of nodular cast iron.

Abstract: 725,212. Fuel injectors. NAPIER & SON, Ltd., D. May 11, 1953, No. 13030/53. Class 7 (3). A fuel injector comprises a housing member 14 and a separately formed nozzle piece 11, and a spring-loaded injection valve 16 has a stem sliding in a bore in the member 14 and an enlarged head 26 which lies within a pressure chamber 18 and engages an abutment in the chamber 18 to limit the lift of the valve, a flat seating portion 27 on which normally closes the injection passage 12 leading to spray apertures 13. When the valve is lifted by fuel pressure, the head 26 engages the upper wall of the chamber 18, whereby the lift of the valve is limited and a seal is formed preventing fuel leaking along the valve stem. The valve is positioned eccentric of the axis of the cylindrical part of the member 14 to provide room for a fuel supply bore 20 leading to the chamber 18 and the members 14, 11, are mounted within a screwed sleeve 5 which is clamped within a second mounting sleeve 1 by a clamping ring 8. Gas tight joints are formed by sealing rings 3 and a screw threaded pressure ring 4.

In a coordinate measuring system displaying in inches or millimetres a control 36 issues signals only when the counter is to display in inches; a first signal causes the gate 24 to eliminate one pulse every 63À5 pulses; a second signal changes over a switch 40 to apply the pulses to the counter via a five times bit rate multiplier 51 instead of a two times multiplier 50 while a third signal shifts the decimal point on the display. Inhibit signals for gate 24 are obtained by a six bit counter 26 which repetitively counts to 32 and then back down to zero; on alternative cycles it is immediately preset to one before counting up. The inhibit signals are issued each time counter 26 reaches 32, keeping the maximum error to ¢ pulse. The transducer may use a Moire fringe arrangement with a photoelectric detector.

The base coating may be zinc phosphate; iron phosphate; borax, lime or iron oxalate and silicates. The base coating acts as a carrier for the lubricant and must be able to withstand temperatures between 600F. and 1100F. The lubricant preferably consists of between 5 and 30% by volume of molydisulphide and the remainder any of the well known wire drawing lubricants such as calcium stearate and any of the well known fillers such as lime. Alternatively, graphite, silicone, phosphates, or a mixture of potassium phosphate and sodium tetraborate may be substituted for the molydisulphide. In the figure, wires 18, having said base coating applied through a tube 22, are stranded about the wires 16 and the lubricating mixture is applied via the pipe 22 at a point before the closing die 24.

[Class 41] [Also in Group XXII] Relates to means for electrolytically producing metallic coatings on stainless steel articles such as wire; when of copper or other lubricant metal, the coatings are of assistance in enabling the wire to be drawn by successive passings between dies to a smaller diameter. The annealed wire 2 is first passed through a 10 per cent. solution of sulphuric acid in an electrolytic bath 3 to remove scale, the wire being made the anode, a current density of 75 amperes per square foot of surface being used. After passing through a 10 per cent. hydrochloric acid solution in bath 4 and being washed in cold running water (not indicated in the Figures) the-wire passes as the cathode through a second 10 per cent. sulphuric acid deoxidizing bath 5, a current density of 30 amperes per square foot being used in this instance. From bath 5 the wire passes through cloths 6 soaked in sodium carbonate solution, first to neutralizing bath 7, also of. sodium carbonate solution, and from there through more cloths 8 soaked in sodium carbonate solution to a copper plating (copper cyanide) bath 9, where a current density of 30 amperes per square foot is employed. It is then drawn through dies 10, 11 (where a powdered sodium stearate lubricant is used in addition to the copper coating). Finally the copper coating is removed in a copper cyanide electrolytic bath 12.
