Title: Improvements in lighting fittings
IPC: B64F1/20
Filed: 1947-02-05
Abstract: 660,561. Airfield lighting fittings. GENERAL ELECTRIC CO., Ltd., ADAMS, J. C., and BEGGS, S. S. Jan. 30,1948 [Feb. 5, 1947], No. 3434/47. Classes 75(ii) and 75 (iv) In a lighting fitting adapted to be placed on or in the ground as a contact or taxitrack light for an airfield, refractory means for forming a beam extends only partly around the electric lamp within the fitting and is rotatable around the lamp to effect adjustment of the direction of the beam. A refractory panel 22 consisting of a section of a sphero-drum concentrating lens with parallel vertical prisms, the angle of each prism being constant throughout the length of the prism, is rotatably mounted so as partly to surround an electric lamp 11 in a housing 1 bolted in a recess in the concrete taxi-track and covered by a domed prismatic glass 5; a mask 21 may surround the other part of the lamp. The foot 24 of the panel is made plain and is clamped between two annuluses 19, 23 secured by bolts 16 to a part spherical reflector 12 surrounding the lower part of the lamp 11 and provided with three springs 14 engaged in a groove 15 in the housing; the annulus 19 overlies a lip on the mask 21 and a lip on a hemi-spherical coloured glass cap 20. Two refracting panels independently rotatable or linked together may be fitted to provide two beams. Colour filters may be used and in order to offset the different transmitting powers of filters of different colour a filter of low power is used in conjunction with the refractory panel and a filter of high power without the refracting panel; alternate operation of the filters is effected by a shutter. The spatial form of the beam is that described by rotating a fixed angle about an axis through its vertix and at right angles to its bisector. According to the Provisional Specification the refracting panel may form part of the domed glass cover for the housing. Specification 660,647, is referred to

Title: Improvements in or relating to coal breaking machines
IPC: B02C1/12
Filed: 1935-02-02
Abstract: 446,308. Reciprocating picks. HOPE, H. G., Trigfa Teg, Llwyn Arosfa, TyCoch, Swansea. Feb. 2, 1935, No. 3489. [Class 59] In a coal-breaking machine the teeth 6 of a lower breaking element A are arranged to penetrate a reciprocating screen 2 and an upper breaking element B is arranged to press upon and break the coal that rests upon the top of the teeth of the lower element while they project 'above the screen. The lower set of picks 6 are resiliently mounted on springs 8 and the teeth pass through the longitudinal slats 2a of the screen, the transverse slats 2b being removed in order to provide for the reciprocatory motion of the screen. The upper set of picks are reciprocated in guides 7 by connecting rod 10 and crank 11. The screen 2 is suspended on links 3 and is connected by a link 14 to a transverse bar 15 forming the pivotal connection between the connecting rod and upper set of picks. On the upward movement of the head B the screen 2 is moved upwards and forwards and the coal thereon is deposited over the lower picks 6 and on the downward movement of the head B, the screen moves downwards and backwards and leaves the coal on the points of the picks.. The coal is thus crushed between the opposed picks and the small coal passes through the screen 2 whilst the larger pieces are moved forward by the screen to another set of picks, the picks of which are more closely spaced. A further set of picks may receive the material discharged over the screen 2.

Title: D-c ammeter calibrator
IPC: G01R1/28
Filed: 1961-01-31
Abstract: 980,310. Calibrating electric instruments. DAYSTROM Inc. Jan. 31, 1961 [Feb. 1, 1960], No. 3576/61 Heading G1U. [Also in Division G3] A D.C. supply is arranged to provide a wide range of selected stabilized output currents for calibrating ammeters. Basically, the circuit consists of a full-wave rectifier 73 supplying an ammeter 78 through a selected series resistor e.g., 81, the voltage drop across this resistor being compared with a reference voltage obtained from a reference cell 58 and selected tappings 57, 109 on a potential divider. Any difference between the two voltages is amplified at 107, 113 and 37 to control the current through the control winding of a saturable reactor 34 which is in series with the A.C. supply to the full wave rectifier 73. The reference cell 58 may be checked against a standard cell 61 using calibrating resistors 26<SP>1</SP>, 27<SP>1</SP> and a galvanometer 28. Six main values of output current (i.e., full scale deflections) may be selected by switch 19 which changes the ratio of a transformer 67 feeding the rectifier 73 and also selects the appropriate series resistor 81 etc. Each main value of output current can be coarsely subdivided by a switch 17 which changes the reference voltage tapping 109 and also changes the input voltage to the rectifier 73 by adjusting the tapping on another transformer 46. Fine subdivision of the current values are obtained by further adjusting the reference voltage with a multiturn potentiometer 57.

Title: Improvements in gas exchange apparatus
IPC: B01D19/00
Filed: 1966-01-27
Abstract: 1,130,421. Blood oxygenating apparatus. GENERAL ELECTRIC CO. 27 Jan., 1966 [12 Feb., 1965], No. 3610/66. Heading A5R. [Also in Division B1] A blood oxygenating apparatus comprises a stack of selectively permeable membranes of high area/volume ratio, e.g. of 1 ml. thick silicone rubber, separated by a screen material, e.g. of nylon monofilaments, the stack being so arranged as to provide two sets of alternate passageways, one set of which allows an oxygen stream to flow in parallel across one face of each membrane while a blood stream flows in parallel in the other set across the other face of the membrane, the screen separators acting so as to produce turbulent flow in the passageways. As shown in Fig. 2, membranes 55-58 are separated by screens 50-54 to provide a stack of square plan (see Fig. 1, not shown). By sealing two parallel edges 60, 61 of alternate screen layers, parallel passageways are created therein. Preferably adjacent layers have different pairs of edges sealed, so that flow one side of a membrane is at 90 to that on the other side. The oxygen is passed across the membranes between tubes 40 and 42, and the blood between tubes 41 and 43 (see Fig. 1, not shown).

Title: Apparatus for combating oscillatory movements of structures, for example, ships
IPC: B63B39/04
Filed: 1957-02-01
Abstract: 806,849. Combating oscillations of ship's and aircraft. SALOMON, F. M. M. B. Feb. 1, 1957 [Feb. 1, 1956], No. 3649/57. Classes 4 and 113. [Also in Group XXXII] Apparatus for exerting alternate mechanical impulses on a structure to combat oscillations of a structure, e.g. the rolling of a ship, is adapted to utilize the inertia of a fluent mass, e.g. liquid, which exerts during its transfer between two opposite rotating casings 7 and 7a a useful torque on the reaction members, e.g. 15, 16 and 17 to oppose the rolling motion. The rotating casings 7 and 7a, whose axes of rotation are arranged parallel to the longitudinal axis of the ship, are driven by motors 1 and la, and are supported by bearings 3, 3a and 11, 11a, on pedestals 5, 5a and 12, secured to the deck 4 of the ship. Rims 8, 8a have annular gutters 29, 29a and vanes 13, 14 and 13a 14a. Two radially opposite scoops 19 draw the liquid from the casing 7 and deliver through the passage 17 to the delivery nozzles 28 in the casing 7a, similarly scoops may draw liquid from the casing 7a and supply to the delivery nozzles 37 in the casing 7. To enable the scoops and delivery nozzles to be moved radially, a tube 18 having a piston 23 slides between two tubes 15 and 20 rigidly attached to the pedestal 12. The annular chambers 21 and 22 are connected by conduits to a control box 26 which actuates the radial movement e.g. hydraulically, and is dependent upon an automatic calculating device which determines from detecting members disposed around the ship the characteristics of the ship's motion. The speed of the casings are adjustable by the motors which may may be coupled and clutches and switches may be interposed in the transmission; the casings may be driven by the engines which drive the ship's generating plant. The reaction members may be either rigidly or elastically connected to the hull, and may be provided with a liquid cooling circulation system, while regulating needles may be fitted in the delivery nozzles. Valves may be introduced in the system as may be a liquid reservoir. In an embodiment, means are described whereby the casing 7 is arranged inside the casing 7a, the opposite rotary motion being supplied by one motor with requisite gear wheels.

Abstract: 229,295. Gabler, J. Feb. 13, 1924, [Convention date]. Weft inserters not carrying bobbins, cops, and the like, looms with.-The weft 15, Fig. 5, is inserted at both sides of the loom from bobbins 14, Fig. 2, and for this purpose is guided into the path of the respective weft-inserter 22, 23, Figs. 5 and 8, by a corresponding weft-feeder 10, 11 actuated at times by lever mechanism operated by studs 27 on a cam-disc on a shaft 5 driven by chain gearing. The weft can thus be inserted once or several times in succession from one side of the loom before it is inserted from the other side, and a pattern can be produced by using bobbins at the two sides with weft of different colour. When a weft-feeder is actuated, it is raised at the beat-up so as to lie over the weft extending from the fabric, through guide eyes 17, 16 to the bobbin at that side. When the weft-feeder descends, it moves this weft into the path of the weft-inserter 22, 23 at that side as shown in Fig. 5, whereby the weft is inserted into the shed. Each weft-inserter comprises a fork 22 for pushing the weft to the centre of the shed and a hook for dragging it the remaining way across, as described in Specification 204,143, this withdrawal occurring after the portion attached to the previous pick has been cut. The inserters are also provided with protectors 24 provided with points 25 for dividing the warps. The transfer from the fork of one inserter to the hook of the other inserter occurs at the centre of the shed.
