Title: Improvements in or relating to apparatus for producing a plurality of proportionate liquid pressures
IPC: B60T8/26
Filed: 1945-06-11
Abstract: 603,718. Fluid-actuated valves. ROCKWELL, E. A. June 11, 1945, No. 14778. Convention date, June 9, 1944. [Class 135] [Also in Group XXXIV] In a device for producing hydraulic pressures from an arbitrarily variable inlet pressure in which the relationship between the output pressures is controlled, adjusting means is provided for maintaining a substantially constant ratio of adjustable magnitude between the output pressures throughout the range of the inlet pressure. As applied to a braking system for a vehicle, a controlling hydraulic fluid of which the pressure is varied by manual means flows through a conduit 44, Fig. 3, into a chamber 114 where it acts on a piston 119. The resulting movement of the latter is applied through a tappet 123, a lever 79 pivoted at 81, a tappet 76, a lever 80 pivoted at 82, a tappet 88, and a piston 91, to open a valve 96 and allow the pressure liquid in chamber 114 to flow through a conduit (not shown) and a chamber 109, past the valve, and into a chamber 105 from which the liquid is applied to the brake cylinders through a conduit 9. A connection may also be taken from chamber 105 through a port 106. Pressure liquid in chamber 114 may also be tapped off through port 116 to provide a second pressure liquid whereby the various brakes of the vehicle may be operated at differential pressures. The differential of pressure between the liquids in conduits 44, 9 may be varied by altering the position of tappet 76 along the levers 79, 80. For this purpose the tappet is carried by a plunger 67 spring-loaded to a central position, but movable by means of a Bowden wire 33 which, at its other end, is attached with a lost-motion connection 28, Fig. 9, to an operating lever 12. The latter moves over a scale and is held in its adjusted position by a tooth-and-rack device. The movement of the plunger is restricted by a pin 73 housed in a groove in the plunger, this arrangement also preventing the plunger, from rotating. With the device shown operating only the front set of brakes on the vehicle, a second, similar, device may be incorporated to operate the rear brakes.

Title: Improvements in or relating to radio receivers and the like
IPC: H03G11/00
Filed: 1937-05-28
Abstract: 496,246. Wireless receiving systems. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. May 28, 1937, No. 14879. Convention date, May 28, 1936. [Class 40 (v)] When noise impulses are present in the detected audio-frequency signals of a radio receiver, the mixture of signals and noise is interrupted at a high frequency and the inter. rupted signals are removed by a low-pass filter. As shown the grid circuit of the first audiofrequency amplifier 19 is shunted by a limiting diode 26, biassed to be conducting for signals exceeding a predetermined amplitude, and a valve 25 to the screen grid of which is connected a source 36 of super-audible frequency. An auxiliary diode detector 55 coupled to the input 6 of the signal and A.V.C. diodes 7, 8 respectively produces a bias across its load resistance 59, when signals exceed a predetermined amplitude, which overcomes a paralyzing bias on the grid 63 of the valve 26 due to the source 61, so that the noise impulses are replaced by potentials of the frequency of the source 36 on the grid 18 of the valve 19. This frequency is removed from the output circuit of the valve 19 by a low,pass filter 44, thus replacing a noise impulse by a period of zero output.

Title: Improvements in or relating to electric phase shifting circuit arrangements
IPC: H03H7/20
Filed: 1950-06-14
Abstract: 668,708. Phase displacement. PHILIPS ELECTRICAL INDUSTRIES, Ltd. June 14, 1950 [June 16, 1949], No. 14885/50. Class 38 (ii). A variable phase shifting bridge comprises a series combination of a transformer winding 2, a variable inductance 3 and a resistance 4, a voltage variable in phase being taken from a load 7 which is connected between a tapping 5 on the transformer winding and the junction between the variable inductance and the resistance, the arrangement being characterized in that the load is shunted for the greater part by a condenser 9, the value of which is such that the total load is capacitative. This value is also chosen such that when the inductance 3 is adjusted to its maximum value the current through the condenser is several times as great as the current through the inductance and when the inductance 3 is adjusted to its minimum value, the condenser current is several times less. With this arrangement a phase shift of at least substantially 180 degrees is obtainable and the arrangement may be used for the control of discharge tubes from substantially no load to full load. In this case the load 7 may take the form of a saturable transformer, thereby giving a peaky waveform to the control voltage.

Title: Improvements in or relating to electric metal-vapour discharge tubes
IPC: C09K11/68
Filed: 1941-11-19
Abstract: 549,810. Metallic-vapour discharge lamps. PHILIPS LAMPS, Ltd. (Naamlooze Vennootschap Philips' Gloeilampenfabrieken). Nov. 19, 1941, No. 14890. Drawings to Specification. [Class 39 (i)] A metal-vapour discharge lamp contains two or more superimposed layers of luminescent material, the more durable material being more remote from the discharge than the less durable material. Durability is determined by the percentage falling-off in output in 1,000 hours of similar lamps each containing a separate material under test; or separate parts of the same tube may contain layers of different materials and the output from these parts is compared. In an example, blue magnesium tungstate alone gave 15 per cent falling-off, while yellow zinc-beryllium silicate activated with manganese gave 40 per cent. Superimposing the silicate on the tungstate in accordance with the invention gave only 20 per cent falling-off, while the reverse arrangement gave 35 per cent. Phosphoric acid is used as the binder.

Title: Improvements relating to methods and apparatus for forming briquettes from plastic paste
Inventor: RAMSE KRISTIAN FREDRIK LANGFEL
IPC: C10L5/14
Filed: 1954-05-20
Abstract: 752,954. Moulding briquettes of electrode material &c. ELEKTROKEMISK AKTIESELSKAP. May 20, 1954, No. 14908/54. Classes 70 and 87(2) Briquettes of, e.g. electrode material are made by moulding plastic electrode paste in a rotary moulding machine. The paste may be of other material than that particularly suitable for electrodes and is made from solid particles, e.g. crushed and calcined carbonaceous material mixed with a water insoluble thermoplastic binder, e.g. pitch or tar and is kept warm and plastic in a hopper 5 with a jacket 6, through which warm oil is circulated, and with heat insulation 7. The mould cavities are in the surface of rollers 1 which are mounted side by side and are rotated in opposite directions so that corresponding cavities form complete moulding spaces where the rollers meet. The rollers are hollow, thin-walled and of good heat-conducting material, e.g. brass or aluminium and are cooled internally by liquid supplied through conduits and nozzles in the shafts 2 and are cooled externally by sprays 4. The liquid is usually water but for paste with a low softening point it may be a special cooling liquid, such as salt solution, circulated in a closed cycle. The material from the hopper comes in contact with the wet and cool mould surfaces and a solid skin is formed on it as the rollers slowly rotate from a to b; where the rollers meet, briquettes are formed with solid shells and liquid or semi-liquid interiors. There is an optimium speed for a particular composition of material, examples being given in the Specification. The moulded and partly solidified briquettes drop into water in a bath 8 as the lower surfaces of the rollers move apart, and their interiors are cooled and solidined. They fall on a wire band conveyer 9 which carries them away for suitable disposal. One example of paste compositions comprises 70 per cent calcined petrol coke and 30 per cent pitch with softening temperatures 80‹C. Another example comprises 40 per cent quartz, 30 per cent aluminium oxide and 30 per cent pitch with softening temperature 70‹C.

Title: Sliver handling apparatus
IPC: D01G21/00
Filed: 1971-05-14
Abstract: 1345450 Handling; crimping and coiling fibres BURLINGTON INDUSTRIES INC 14 May 1971 [23 June 1970] 15022/71 Heading D1F In sliver handling apparatus to and from which sliver is continuously supplied and taken-up, any increase or decrease (as sensed according to weight or volume) of an accumulation of sliver supported on a surface of a reservoir causes a corresponding change in the speed of take-up. In the operation of the apparatus of Figs. 2 and 3 which controls the speed of rotation of a coiler can 30 in response to the weight of crimped sliver in a reservoir 28, sliver is delivered through a funnel 34 to adjustably loaded feed rolls 26 of a stuffer-box crimper 46 wherein the sliver is compacted against a spring-loaded end-flap. The crimped fibre then passes along a ramp 49 and surface 49' in a reservoir 28 whence it moves through a conduit 50 and into the sliver coiler 52 to be deposited into can 30. When the accumulation of sliver is sufficient, reservoir 28 pivots about a pin 38 against the resistance of a spring 42 and actuates a microswitch 54 (as determined by preadjustment of set screw 40) thus opening a valve 84 to supply high pressure air to cylinder 78 and compel a piston rod 76 to move an idler arm 72 to the position shown dotted in Fig. 3, whereat belt 62 is moved towards the centre of a spring-loaded sheave 60 to reduce its effective diameter thus causing increased speed of coiler can mechanism through gear box 64. The resultant decreased weight in the reservoir allows it to return to a horizontal position whereupon the coiler can mechanism slows. In the operation of the embodiment of Fig. 4, as sliver accumulates in a reservoir 112, a movable flap 114 is forced upwards to actuate a microswitch 116 and initiate operation of a valve member 108 to supply high pressure air to an air cylinder 102 thus causing idler arm 98 to rotate and force a belt to move within a spring-loaded adjustable sheave 92, reducing the effective diameter thereof thus increasing the speed of the coiler can mechanism and removal of sliver from the reservoir. This speed change reduces the accumulation of sliver so that flap 114 is restored to its former position with a resultant fall in speed of the can mechanism.
