Abstract: 683,200. Boring and facing machines. KEARNS & CO., Ltd., H. W., and KEARNS, Sir H. W. L. Aug. 28, 1951, No. 20247/51. Class 83 (iii). A work table of a horizontal boring machine has an overhanging saddle supported by rollers on tracks, the rollers being covered by the saddle and the portions of the roller tracks with which the rollers are in contact being shielded at each side of the saddle by wipers sliding along the upper surface of said tracks and at each side of the tracks by means depending from the saddle closely alongside and to beneath the level of said tracks. The bed a, Fig. 3, of the machine is provided with lateral extensions on which tracks k support the overhanging portions of a saddle f. The latter moves along the bed a and supports a cross-slide h, Fig. 2, on which the work is mounted. Alternatively, a further revolving table i may be carried on the cross-slide h to support the work. Rollers l carried through ball-and-roller bearings n<SP>1</SP>, n<SP>2</SP>, Fig. 3, by pins o run on the tracks k. The pins o are carried in brackets p, lugs q of which support the saddle and at the same time protect the side flanges of the tracks k from swarf. Additional filling pieces s secured to the saddle cover part of the exposed sides of the tracks below the saddle, other strips t complete the side protection and engage grooves u in the bed to act also as holding-down members. Wipers r, Fig. 2, protect the top surfaces of the tracks at each side of the saddle.

Abstract: 709,874. Two-part couplings. THOMAS & BETTS CO. Aug. 12, 1952, No. 20251/52. Class 38(1). [Also in Group XXV] A terminal adapted to make electrical and mechanical engagement with an identical terminal comprises a unitary metal member formed at one end with a wire-receiving sleeve 3 and slotted at 5 to form a pair of resilient prongs. Each prong is formed with an ear 9 providing a flange 10, the distance between the underneath of the ears and the terminal body being slightly greater than the thickness of the terminal, the distance between flanges 10 being slightly less than that between edges 4 of the body, and the minimum distance between ears 9 being slightly greater than the width of the terminal shank 2. In making a connection the two connectors are placed so that their sides carrying the ears 9 face each other and each shank 2 is passed between the ears 9 of the other connector. The connectors are then pulled apart whereupon the edges 4 are forced between the flanges 10 to establish electrical contact and the ends 12 of the ears 9 abut one another to provide positive mechanical locking. Additional mechanical latching may be provided comprising a recess 14 leading to a cam surface 15, the cams 15 climbing one another during the connecting operation and the peaks passing each other just prior to the engagement of surfaces 12, Fig. 11. A boss 17 pressed out of the recess 14 prevents engagement of the connectors if one should be upside-down.

[Also in Division H3] Fine control of the temperature compensation of a simulated Zener diode structure of the kind described in the parent Specification is obtained by means of an additional transistor structure having its collector formed in the common collector zone and having a first resistor connecting its emitter to its base and a second resistor connected to its base, the emitter and the end of the second resistor remote from the base forming terminals which are inserted at some point in the series chain of forward and reverse biased emitter junctions, one of the resistors being adjusted by means of an at least partial short circuit. As shown, Fig. 2, a plurality of transistor structures, some of which have double emitters, are formed with a common collector region and are connected so that their emitters form a plurality of reverse biased Zener junctions in series with a plurality of forward biased junctions to provide temperature compensation. An additional transistor structure T is provided together with resistors R 1  and R 2  which are inserted into the series circuit. Resistor R 2  is adjustable and this is achieved by depositing a layer of metal over it during the manufacture of the device to provide a short circuit, measuring the temperature coefficient of the completed device and selectively removing parts of the metal layer short circuiting R 2  to provide the fine adjustment of temperature coefficient. The resistors may be formed as diffused regions arranged in the common collector zone, or as resistive tracks on the surface.

Abstract: 585,240. Radial flow turbines. THOMAS, D. W. Sept. 11, 1944, No. 20840. Divided out of 585,229. [Class 110 (iii)] A triple expansion turbine comprises three concentric rotors held between a pair of side plates and having channels for the working fluid, which may be steam, water, or air. The innermost rotor is the H.P. and the outermost the L.P. and the fluid passes from one rotor to another through suitable holes or passages in the circumferential dividing walls. The channels in the intermediate rotor are curved oppositely to those in the other rotors. Fluid enters at P and passes through a pedestal F<*>, around shaft D, and through a valve V to flow successively through spiral channels in the high pressure stages A ; thence through passage S<1> and valve V<2> to intermediate stages B ; and thence through passage S<3> and valve V<5> to low pressure stages C, finally exhausting at R. Valves V, V and V are held in the open position by the fluid to obstruct the corresponding passages S, S<2> and R* respectively. Reversal is obtained by admitting fluid at P<*>so that the rotor channels are traversed in reverse sequence. Valves V<1>, V<3> and V<4> are then opened by the fluid, to obstruct the corresponding passages S<1>, S<3>, and R respectively. Exhaust takes place through R<*>.

Title: Production and purification of titanium
IPC: C22B34/12
Filed: 1951-09-05
Abstract: Titanium or an alloy of titanium and a volatile metal of the group consisting of zinc and lead is produced by reacting titanium-bearing material at elevated temperature and preferably at reduced partial pressure with the support of one or more halides of the group consisting of chlorides, bromides and iodides of the volatile metals, thus forming the vapour of the volatile metal and a stable titanium halide, leading the resultant vapours into a condensing zone which is provided with an excess of the volatile metal so as to convert the titanium halide into the halide of the volatile metal and an alloy of titanium with volatile metal which condenses and evaporating all or any desired amount of volatile metal from the alloy.  The halide of the volatile metal used is preferably zinc bromide or chloride.  The excess volatile metal in the condenser may (a) be present in the form of a liquid pool, (b) be introduced as a liquid or vapour stream at a predetermined rate relative to the rate of entry of and in countercurrent to the reaction vapours to ensure complete conversion of these vapours, or (c) be passed over the titanium bearing material together with the volatile metal halide vapour and the resultant mixed vapour led to the condenser.  An inert gas, e.g. argon at reduced pressure may be used to carry the volatile metal halide over the titanium-bearing material. Specification 666,869 is referred to.

Abstract: 914,105. Centrifugal pumps. DOWTY FUEL SYSTEMS Ltd. June 6, 1961 [June 15, 1960], No. 21057/60. Class 110 (1). In a liquid supply system including a centrifugal pump supplying pressure liquid to an hydraulic load from a low-pressure source, the pump includes a throttle valve balanced with regard to the low pressure for controlling liquid flow into the pump, the throttling portion of the valve being located within or closely adjacent the centre of the pump impeller and the liquid assuming an annular form within the pump, the radial depth of the liquid annulus controlling the output pressure and the central core within the annulus being substantially at the vapour pressure of the liquid. In the centrifugal pump shown, in which the arrangement is such that a central core or cavity substantially at the vapour pressure of the liquid is formed in the liquid at the inlet to the impeller 3 as described in Specification 842,354, the liquid flow is controlled by a throttle valve comprising a cylindrical sleeve 13 which is axially slidable to adjust the effective size of ports 11 in a fixed sleeve 9. The sleeve 13 is actuated by hydraulic pressure applied through ducts 21, 22 to either side of a piston portion 18, a spring 19 urging the sleeve in a direction to uncover the ports 11. Preferably, the sleeve 13 is rotatably driven through gearing 15, 16 so as to reduce its frictional resistance to axial movement. Each port 11 produces a radial stream of liquid within the impeller to reduce the extent of liquid atomization.
