Title: Improvements relating to electrical measuring instruments
IPC: G01R11/40
Filed: 1922-07-22
Abstract: 196,525. Metropolitan-Vickers Electrical Co., Ltd., (Westinghouse Electric & Manufacturing Co.). July 22,1922. Polyphase transformers; phase, changing.-In order to measure the volt-amperes in an alternating-current circuit, the current supplied to the pressure coil 14 of a wattmeter 4 is brought into definite phase relationship with that supplied to the current winding 11 independently of the power factor of the circuit 'by a motor device 5 having a rotatable winding 6 connected to the mains 1 through a pressure transformer 3, a stationary winding 10 connected to the circuit through the current windings 11 of the wattmeter 4, and a third stationary winding 13 in inductive relation to the winding 6 and connected to the pressure coil 14 of the wattmeter. Whatever the power factor, the rotatable winding 6 takes up a position of no torque, in which there is a definite phase relationship between the currents in the windings 10, 6 and consequently between those in the windings 10, 13. In a modification, Fig. 2, the winding 13 is dispensed with and the connections 15 to the pressure coil are taken from points between the conductors 12 leading to the current windings 11. In a further modification, the pressure coils of the wattmeter are connected to the conductors 12, which are connected to the secondary circuit of the current transformer 2 through step-up transformers, thereby enabling the ampere-turns. on the windings 6, 10 to be more nearly equal. The current windings of the watt-meter in this case are star-connected. A previously suggested apparatus for the same purpose is mentioned, in which a transformer with relatively movable primary and secondary members is controlled by a motor device the position of the movable member of which is controlled by the power factor.

Title: Improvements in or relating to television apparatus and the like
IPC: H04N3/04
Filed: 1928-07-11
Abstract: 321,441. Baird, J. L., and Television, Ltd. July 11, 1928. Television.-In an apparatus for stereoscopic television, two aspects of an object or scene are transmitted successively through a single communication-channel and reproduced in juxtaposition, at such a rate as to be within the persistence of vision of the observer, which involves the transmission of some 12 images of each aspect per second. The scanning disc 14, Figs. 2 and 3 is provided with two sets of holes 10, 11, Fig. 1, lying on spirals whose " operative points " are 12 and 13 respectively, and which are spaced any desired distance apart, e.g. the spacing of human eyes. In the transmitter, Fig. 2, the light sources 17, 18 scan the object 21 alternately, and from a different angle, through the spirals 10, 11, whose fields are represented as 15 and 16 respectively, and light from the sources, reflected from the object, is received by the light-sensitive cells 22, 23 respectively. At the receiver Fig. 3, glow discharge lamps 24, 25 in conjunction with an identical scanning disc 14, produce two images in alternation which are in juxtaposition and are viewed by a stereoscope 26. Exaggerated stereoscopic effects may be obtained by using scanning discs of the type shown in Fig. 4, in which 30, 31 are the widely spaced " operative points " of the spirals 28, 29 respectively. Colour effects may be obtained by reproducing one picture in red and the other in blue by using a filter of appropriate colour with each spiral on both scanning discs. For a three-colour process the disc 32, Fig. 5, is preferably used in which the three outer spirals 33, 34, 35 have an " operative point " 39, and the three inner spirals 36, 37, 38 have an " operative point " 40, the spirals of each group being provided with blue, green, and red colour filters respectively, arranged in any desired sequence. An alternative scanning scheme employs a disc 41, Fig. 6, having two spirals 42, 43 extending substantially all round the disc, having " operative points " 44, 45, respectively, and whose corresponding light-apertures are on different but adjacent radii so that at any given time one band only of one of the pictures is being explored, and the transmission consists of a series of intercalated bands from the two images. The light-apertures in the scanning discs may be replaced by lenses, mirrors, or the equivalents. Specification 266,564 is referred to.

Title: Improvements in or relating to Stud and Socket Fasteners.
Inventor: BLOXAM ARTHUR GEORGE
IPC: A44B17/00
Filed: 1918-12-06
Abstract: 136,229. Bloxam, A. G., (Carr Fastener Co.). Dec. 6, 1918. Press-button fasteners.-In a stud-and-socket fastener of the kind in which the socket has on one side of its aperture a rigid jaw and on the other side a yielding jaw to engage the stud head, the fixed jaw and casing of the socket are so constructed that the stud can only be withdrawn when the stud and socket are tipped relatively to each other in a single predetermined direction. The socket, Fig. 2, comprises a casing 20 attached to the fabric 26 by prongs 28 passing through two plates 25, 27, the apertures in which are so formed that the stud 4 can be tipped only in one direction. The casing contains a spring 23 forming the yielding jaw 24, and has an aperture, one edge 21 of which is depressed and recessed to form the fixed jaw. The distance between the jaw 21 and the other edge 24 of the aperture is such that the stud will jam if withdrawal by a direct pull is attempted. The stud is formed with a gently inclining cam-surface 7 joining the head 5 and neck 6, so that when it is tilted, as shown in dotted lines, the spring 24 is pressed back, allowing the stud to be disengaged from the fixed jaw 21. In another form, the fixed jaw 21 is pressed up from the intermediate plate 25, and the top of the casing is pressed outwards, forming 'supporting-surfaces for the head of the stud.

Title: Improvements in and relating to smoke consuming devices for boiler and other furnaces
IPC: F23M3/00
Filed: 1928-07-12
Abstract: 320,407. Kelly, A. R. July 12, 1928. Firebridges; doors; liquid and gaseous fuel furnaces.-To consume smoke, a controlled supply of air, pre-heated in a special construction of bridge, is delivered transversely to the gases passing over the bridge and additional preheated air is supplied at the front or other convenient part of the combustion chamber. The bridge air, after being heated beneath the grate, is delivered through a valve 10 below the grate level and adjustable from the front, to the bridge. Here the air travels first upwardly, then forwardly, then upwardly and rearwardly and finally is deflected upwardly by a secondary bridge wall 6. The front air supply is preheated in flue-pipes 20, or it may be in the ash-pit or elsewhere, and is then admitted to a perforated distributing-box 28, Fig. 5, on the inside of the fire-door. For this purpose a pipe 27 connected to the box 28 makes joint, when the door is closed, with the air supply pipe at 25, Fig. 4, such joint including a spring-controlled sleeve 32 fitted with packing. The invention is applicable also to furnaces, when fitted with bridges, fired by oil or by combustible waste gas or producer gas or the like.

Title: Improvements in or relating to means for carrying spare wheels on motor vehicles
IPC: B62D43/00
Filed: 1930-07-04
Abstract: 353,223. Spare wheel holders. THORNYCROFT & CO., Ltd., J. I., Thornycroft House, Smith Square, London, and ALLEN, H. F. G., Old Basing, Basingstoke, Hampshire. July 4, 1930, No. 20327. [Class 136 (i).] A spare wheel carrier, more particularly for heavy motor vehicles, comprises a plate 4, adapted to turn about a horizontal hinge pin 3 on a plate 2 secured to the side member 1 of the chassis, and a second plate 5 adapted to support the spare wheel 7, as by means of a pin 6, clamping-plate 8, and locking-nut 9, and pivoted to the plate 4 on a fulcrum pin 10 eccentric to the pin 6, the plates 4, 5 being adapted to be locked together, as by a spring-urged bolt 11, and moved from a vertical position into a horizontal position beneath the chassis, in which position the wheel 7 is held in a support 14 carried by angle brackets 15 from the chassis member 1a, and from which the plates and wheel can be moved back into the vertical position for removal of the wheel, the arrangement being such that the wheel is at all times supported by the carrier until it is brought into contact with the ground. The bolt 11 slides in guides 12 on the plate 4 and normally engages a lug 5a on the plate 5, and it is adapted to be withdrawn by means of a knob, finger ring, &c. 11a and then held by rotating it to engage a projection on it with one of the guides 12. The plate 5 and wheel 7 can then be rotated about the eccentric pin 10 to withdraw the wheel from the support 14, when the plates 4, 5 and the wheel may be turned about the pin 3 into the vertical position. The plates and wheel are then moved sidewise along the pin 3, and are prevented from turning back under the chassis by the engagement of the plate 4 with projections 2a on the plate 2. The plate 5 and wheel 7 are then turned about the pin 10 until the wheel touches the ground for removal.

Title: Improvements in or relating to hydraulic follow-up devices for assisting a relatively small force
IPC: B62D5/08
Filed: 1945-08-08
Abstract: 598,087. Fluid-pressure servomotor - control systems. INTEGRAL, Ltd., and WORLIDGE, R. F. Aug. 8, 1945, No. 20335. [Class 135] In a fluid-pressure servomotor for transmitting the movements of, e.g. a steering-wheel to the road wheels of a vehicle, the hollow piston-rod 10, Fig. 1, of a piston 9 is connected by a ball-ended member 19, Fig. 2, to the road wheels, whilst a tubular valve member 8 having an end disc 12 is slidably mounted in the rod 10 and, through a coupling-rod 23, biassed by a spring 22 to contact a socket-member 20 which engages the bottom of the steering column. The member 20 is slidable with limited movement between cushioning springs 21 in the member 19. The cylinder 3 is closed by a head 4 having an inlet 25 and a drain 26 and carries concentric tubes. 5, 6 whose other ends are secured to a head 7 over which the valve member slides. A spring- mounted valve 27 is operated by pressure fluid to connect the inlet with a passage 13 and when the pressure fluid is not available the passage 13 is connected to the drain. Pressure fluid after passing through the passage 13 enters the space between the tubes 5 and 6 and emerges therefrom through holes in the outer tube adjacent to the head 7, traverses the space between the outer tube and the valve 8, passes through ports 15, and, when the parts are in the balanced position shown, to both sides of the piston through passages 16, 17 respectively. The ports 15 are arranged so that the left-hand side of the piston, which is half the crosssectional area of the right-hand side, is always open to pressure fluid whilst the right-hand side can be opened to drain via the undercut 18 on the valve 8, the holes through the valve adjacent its end 12 and the bore of the inner tube 5. In operation, a movement of the steering-wheel to move the valve to the right progressively cuts off the supply of pressure fluid through the ports 15 to the right-hand side of the piston and opens that side to the drain, whence the piston will follow the movement of the valve in a rightward direction until the valve is stopped when the valve and piston will again occupy a balanced position. On movement of the steering-wheel to move the valve to the left, the ports 15 open the right-hand side of the piston fully to pressure fluid supply and at the same time the opening through the undercut 18 to the drain is cut off, whence, due to the difference in areas of the two sides of the piston, the piston will follow the movements of the valve leftwardly until the valve is stopped when they will again occupy a balanced position.

Title: Improvements in hypodermic injection apparatus
IPC: A61M5/24
Filed: 1948-07-30
Abstract: 652,945. Hypodermic injection appliances. BECTON DICKINSON & CO. July 30, 1948. No. 20359. Convention date, July 30. 1947. '[Class 81(ii)] In a device for projecting liquids through the skin by pressure and velocity, the expelling means is first cocked and then released by continuing pressure on the actuating mechanism. In one form of the device the ampoule is held in a central recess in a plug 42 fitted in a body member 10 and is retained by a plug 43 having a convex outer face and a central cannula 44, the inner end of which pierces the lower end of the ampoule. When the instrument is used a plunger rod 12 is lifted against a spring 20 by engagement of a projection 23 with a plate 13, the projection being on a sliding member actuated by gripping' the handle 26. At the top of the stroke a cam surface 24 on the sliding member engages a stop 25 and disengages from the head 13, whereupon the plunger is thrust violently downwards against the ampoule so as to expel the contents. For subsequent use the plunger is restored to the position shown by being lifted by the handle 16 the lower end of the tubular' centre member 17 engaging the head 15. The ampoule may be of pliable plastic material, in which case it may be crushed by the plunger or it may be a glass tube having a piston-like rubber plug at each end, the upper one of which is displaced by the plunger. In a modification the sliding member is replaced by a lever arrangement which disengage from the plunger to release it, at the end of its travel, see Fig. 7 (not shown).

Abstract: 350,278. Recuperative furnaces ; pipe joints. WHITE, A. E., 5, Quality Court, Chancery Lane, London.-(Morgan Construction Co. ; 15, Belmont Street, Worcester, Massachusetts, U.S.A.) July 4, 1930, No. 20361. [Classes 51 (i) and 61 (ii).] In a recuperator vertical tubes 23 through which the waste gases pass downwardly are supported on and interlocked with an apertured bottom plate 27 to prevent such relative vertical movement as would destroy the seal which each tube makes with the bottom plate. The Tecuperator is arranged within the end wall 13 of the billet heating furnace shown, the waste gases from the heating chamber 11 passing downwardly through vertical tubes each comprising top and bottom sections 25, 24 and a number of intermediate sections 26 joined by telescopic interlocking joints sealed with packing material. Each aperture 28 in the bottom plate 27 has an upstanding flange 30 provided with opposite exterior lateral projections 31, Fig. 5, and adapted to be received within the enlarged lower end 32 of the bottom tube section which has internal segmental projections 33 leaving gaps adapted to pass the projections 31, after which the tube section is turned through 90‹ to interlock it with the bottom plate. The joints are sealed with packing material 34 and sand a. The intermediate sections are similarly interlocked with each other and each top section has a plain upper end passing through an aperture 41 of a top plate 42 and encircled by an upstanding flange 44 of the top plate, the annular space being sealed by asbestos 45. The upper sections are formed of chrome nickel steel to withstand the high temperatures. Heat radiating ribs 46 are provided on each tube section and transverse baffles 47 force the ascending air to travel between the ribs. The top and bottom plates are supported by projections 43, 29 on the brick walls of the furnace. A flue 12 connects the tubes 23 with the stack, while the cold air is supplied from a flue 10, and the heated air passes beneath the floor 6 of the heating chamber to a port 4 adjacent the gaseous fuel supply passage 2. The billets are charged on to the hearth 6 through a side door 16 and moved through the furnace by a pusher 15, a guide 61 preventing them from passing on to the pusher skids 17 overlying the recuperator so that no scale from the billets can fall into the tubes. The pusher skids 17 are made hollow and supplied with cooling air or water by a pipe 20 from the cooling space 19 beneath the hearth, the cooling medium being removed by a pipe 21.
