Title: Improvements in or relating to electric carrier wave signalling systems
IPC: H04B3/10
Filed: 1941-03-28
Abstract: 546,217. Repeating systems. STANDARD TELEPHONES & CABLES, Ltd. March 28, 1941, No. 4182. Convention date, April 3, 1940. [Class 40 (iv)] Each pair in a carrier cable carries three pilot currents, one for controlling the flat gain, another for controlling a slope network, i.e. adjusting the slope of the attenuation characteristic, and the third for controlling a bulge 'network, i.e. controlling the maximum amplitude of the attenuation characteristic without changing its shape, and it is arranged that if a pilot current fails, control of the element concerned is effected by the corresponding pilot currents of other pairs. In the arrangement shown, the pilot currents are filtered off at 23, separated in the anode circuit of a valve 26 and rectified by voltagedoubler-type metal rectifiers and the resulting voltages control the anode currents, which are derived in part from an A.C. generator 58, of valves 48, 69, 87. The output currents are fed in part to the heaters of variable resistance elements 10, 13, 16 associated respectively with the feed-back path of a flat gain amplifier and with slope and bulge networks and in part over resistances such as 60, 61 to control-buses such as 62 which are similarly associated with the pilot channels of other pairs. If, say, the pilot channel controlling resistance 10 fails, the resistance continues to be controlled over circuit 62 by the corresponding pilots of the other pairs. Specifications 469,667, [Group XIII], 508,341, [Group XL], and 540,844, [Group XXXVI], are referred to.

Patent GB-881380-A (GB)
Title: Improvements in storage arrangements for wheeled vehicles
Inventor: BAILEY BASIL FREDERICK THOMAS
IPC: E04H6/26
Filed: 1957-02-08
Abstract: 881,380. Storage of vehicles. POWER PARKING Ltd. Feb. 7, 1958 [Feb. 8, 1957], No. 4344/57. Class 78 (4). Cars are handled for parking purposes (e.g. in a multi-storey garage) by tilting platforms along which the car runs. In Fig. 3, the platform 86 is pivotally carried by lift platform 103 and is biased by a weight 89. Platforms 95, 96 at each level are pivoted and biased to tilt outwards, and the transfer of cars to and from the lift platform 86 is achieved by first locking the platforms concerned, as at 104, then suitably positioning the lift and retracting the appropriate stop 91 or 92. The entrance and exit ramps at ground level are sloped towards and away from the lift respectively, and retractable stops are provided at their forward ends. The lift is capable of stopping at three different positions for each floor level (indicated at H, M, L). In a second embodiment (Fig. 11) the platform 32 is mounted on adjustable mountings 34, 35 on lift platform 33. A tiltable entrance ramp 29 is normally locked in alignment with the approach road 28 (which may be sloping upwards), but can be tilted as shown to load the car 42 on to the lift. The slope of platform 29 in the position shown may be less than that of all the other platforms, so that if a car rolls freely on to the lift it can be assumed it will roll freely throughout the system. Each platform preferably has a trough or channel along one side to guide the car wheels. The car is discharged from the lift at any level in a manner similar to that of the first embodiment. The lift is mounted in a tower which may be movable horizontally to serve a number of columns. On restricted sites a turn-table with a sloping ramp may be used in the approach road. In another arrangement the lift platform is circular and rotatable to serve a number of columns arranged radially around the tower. In yet another form a " big wheel " is employed, Fig. 27, the cars being accommodated in cages 121 with tilting platforms and the lift tower being at 128. The tilting platform in the lift must, in this case slide forward to bridge the gap needed for clearance of the wheel framework. A form of bolt for locking two platforms together (shown at 104, Fig. 3), is shown at 135, Fig. 29. The bolt slides in guides 136, 137, and the latter allows limited vertical movement to allow for slight mis-alignment of the platforms 133, 134. The bolt may be poweroperated and is normally held central by buffers or springs 138, 139.

Filed: 1940-03-08
Abstract: 539,443. Making rock drill bits. RIP-BITS, Ltd., PADLEY, L., and MORGAN, G. A. March 8, 1940, No. 4356. [Class 124] [Also in Group XXII] In a rock drill in which the drill bit is attached to the drill rod by means of a separately formed connecting member seating in and projecting from a socket in the bit, the drill bit c is formed into shape between dies by the single step of forging a heated solid metal slug a in contact with a preformed connecting member b. During such formation the connecting member penetrates the slug, and thereby forms, and becomes seated in, the socket of the bit simultaneously as the slug is transformed to drill bit shape. The connecting member may be solid, or axially drilled for a part or the whole of its length, and the two parts are then drilled, either axially or from one side, Fig. 8, to form a passage e for flushing water. The connecting member may be screw-threaded, with or without interruptions, g, Fig. 6, or its embedded portion may be of dovetail or like formation to prevent relative axial or rotational movement.

Title: Improvements in, and relating to, motor power plant
IPC: F02G3/02
Filed: 1921-02-09
Abstract: 178,617. MacAlpine, T. W. Feb. 9, 1921. Motor power plant.-Air drawn into a separating plant A is separated by the Claude or another process into oxygen and nitrogen, and the oxygen is delivered by a compressor B to a combustion chamber C wherein fuel is burnt, the products of combustion being used to drive an engine or turbine D, which may exhaust through a cooler E, serving to heat the nitrogen or the other working fluid of its cycle. The nitrogen is delivered by a compressor M to the combustion chamber heater H, where part of it may mix with the combustion products, the main supply, however, being used to drive the engines or turbines K, P, preferably expanding to a sub-atmospheric temperature and returning either wholly or in part to the separator A. Other gases may be used instead of oxygen and nitrogen.
Patent GB-831434-A (GB)
Title: Improvements relating to the production of artificial slub yarns
Inventor: TALLIS ERNEST EDWARD
IPC: D01D5/20
Filed: 1957-02-12
Abstract: <PICT:0831434/IV (a)/1> Artificial multifilament yarns of one colour having slubs of a different colour are made by extruding through a spinning jet a first fibre-forming liquid at uniform pressure having the colour of the yarn, and intermittently interrupting the flow of the first liquid to the jet face by injecting intermittently, at a pressure greater than that at which the first liquid is supplied to the spinning jet, a second fibre-forming liquid having the colour of the slubs at a point immediately behind the jet face, but spaced sufficiently from the jet face to allow the first fibre-forming liquid to regain access immediately to the whole of the jet face and to resume extrusion at the end of a slub formed from the second fibre-forming liquid which, being extruded at a greater pressure, has a higher volumetric rate of extrusion than that of the first fibre-forming liquid.  Preferably, immediately after the cessation of the supply of the second fibre-forming liquid to a point immediately behind the jet face, the pump controlling the liquid sucks back a small quantity of the liquid to provide a sharp change of colour and denier at the tail end of the slub.  As shown, a conical spinning jet 1 is secured to a rounder end 2 by a screwed coupling 3, a seal being formed by the rubber ring 4.  A nozzle 5 is supported centrally close behind the face 6 of the jet 1 by radial centring members 7.  The nozzle is connected by a pipe 8 provided with a strainer to an injector-type pump (described in Specification 812,022) which delivers coloured viscose in sharply-defined pulses at a pressure higher than that of the clear uncoloured viscose supplied at a uniform rate through the rounder end 2 by a gear-type metering pump. The injector type pump may be actuated by a cam or by a pneumatic piston in a cylinder to which the supply of air is controlled by an electromagnetically-operated valve.  The pipe 8 is made rigid and as short as possible, to reduce its elasticity to a minimum and thus obtain sharp changes in colour at the ends of the slubs.  The spring-loaded delivery valve in the injector pump may itself be shaped as a plunger working in the delivery valve chamber, so that it sucks back slightly as the valve closes, thus absorbing any "tailing" effect due to the unavoidable small elasticity of the pipe 8.  The jet 1 is immersed in a regenerating bath and the threads are taken over a guide positioned above the surface of the bath and then underneath a guide positioned beyond it in the bath to a godet or other take-up device.  The first guide has the effect, particularly necessary at spinning speeds above 50 metres per minute, of preventing the slubs in the various individual filaments from moving longitudinally and thus becoming displaced. French Specifications 766,852, 803,144 and German Specification 741,595 also are referred to.
