Title: Improvements in processes of drying peat and other aqueous materials
IPC: F26B17/20
Filed: 1943-05-03
Abstract: 566,668. Drying peat. FAIRWEATHER, H. G. C. (Aktiebolaget Torkapparater). May 3, 1943, No. 6968. [Class 34 (ii)] . Aqueous materials, such as peat, are dried in two or more stages, the hot vapour obtained in one stage being used as heating agent in another stage. In a two-stage apparatus I, II, at high and low temperature respectively, each heating unit comprises tubes 4 mounted on rotatable tube plates 2, 3 which also divide the container 1 into three compartments 5, 6, 7, the compartments 5, 7 comprising inlet and outlet headers for heating medium, and compartment 6 comprising a drying chamber. The tubes 4 may have loose internal members to transmit heat and clean the heat transmitting surfaces during rotation. Flue gases are employed for heating apparatus I, and are reduced to 400-600‹ C. by admixture with cool gases from header 7 supplied by blower 11. Peat passes through from 8 to 9 in the same direction as the heating gas. Vapour expelled from the peat is carried off by some of the flue gas from furnace 10, mixing chamber 5, or outlet chamber 7, and is admitted to inlet 5 of apparatus II, through which peat passes in the opposite direction from 8 to 9. Latent heat of the vapour is available in apparatus II and condensate passes to outlet 12, and gas to fan 13. Vapour from the chamber 6 is carried off by cool flue gas from apparatus I, the heat content of the gas being used in direct contact with the material, or for heating air or another gas which is used as drying medium. The saturated drying medium from apparatus II may be used as heating medium in another stage, or for preheating the material. Moisture thereby condensed on the material is removed mechanically. Alternatively, effluent gas and vapour from apparatus II may be used in apparatus 15 to preheat air for the furnace combustion.

Title: Improvements in or relating to shuttlecocks for badminton and the like games
IPC: A63B67/18
Filed: 1931-03-07
Abstract: 363,563. Shuttlecocks. SPALDING & BROS, (BRITISH), Ltd., A. G., Deodar Road, Putney, London.-(Assignees of Saunders, A. T. ; Akron, Ohio, U.S.A.) March 7,1931, No. 7155. Convention date, Jan. 26. [Class 132 (iii).] A shuttlecock for the game of badminton &c. comprises a head, and a vane consisting of a coneshaped member of seamless tubular textile fabric secured to the head. The vane 1, Fig. 4, is made by drawing a seamless tube of knitted fabric over a duralumin form 8, Fig. 1, securing it by a rubber band 2 and a cord 3, dipping it repeatedly but to successively smaller depths in a stiffening material (e.g. plasticized glue or pyroxylin with an admixture of sulphide or oxide of zinc or oxide of titanium) so that the smaller end of the vane receives the heavier coating, cutting off the vane to the requisite length, removing from the form and mounting on the head 5. In drawing the fabric tube on to the form, the vane is given a greater density of texture, that is, with smaller interstices, near the smaller end than towards the larger end. When the vane and cone are dipped into a quick-drying solution the increased thickness at the small end of the vane is obtained at a single dipping by a gradual withdrawal, at decreasing speed, from the solution. When a glue compound is used, the vane may be rendered waterproof, after coating, by treatment with formaldehyde. The cone 8 may be lubricated with paraffin or soap to facilitate removal of the vane. The stiffened cone, after removal from the form 8, may be placed in a heated mould and given a fluted edge d, Fig. 5. The flutes may be formed with unequal sides to produce a spinning motion of the shuttlecock in flight. The head 5 is preferably formed of cork and is provided with a covering of colloidal composition, such as rubber, plasticized glue or plasticized pyroxylin with an admixture of white pigment. The colloidal cover may be reinforced by an admixture of silk fibre, paper pulp, felted hair, or by a knitted fabric. The vane is glued or cemented to the head and the usual band 4 is added.

Title: Improvements in thermionic amplifiers
IPC: G01S7/28
Filed: 1950-03-24
Abstract: 667,725. Electric analogue calculating systems. CRONEY, J., and BUCKINGHAM, J. March 24, 1960, No. 7416/60. Class 37. [Also in Group XL (c)] In a multi-stage amplifier, each stage feeds its own detector and the outputs of all the detectors are combined in a common low impedance load through delay circuits which compensate for the successive time delays due to the passage of the signal through the amplifier. The intermediate frequency amplifier of a radar receiver, Fig. 1, comprises ten valves VI ... V10 feeding through .detectors D1 ... D10 individual load resistors R6. Each load resistor is connected to a delay line comprising inductors L3 and capacitors C3 terminated by resistors R7 equal to the characteristic impedance. Since resistors. R7 are small compared with resistors R6, very little voltage is fed back from the last detector D10 to bias back the earlier detectors. As the input to valve VI  increases, the later valves saturate in turn, so that due to the geometric variation in amplification along the amplifier, a logarithmic characteristic results. In order to simulate a further I.F. valve a rectifier D11 is provided biased by resistors R8, R9 to a point at which a further valve would run into grid current. A change-over switch may be provided, Fig. 2 (not shown), to allow the amplifier to operate in a linear manner.

Patent GB-707224-A (GB)
Title: Process for recovering oils, fats or waxes from spent absorbent materials
IPC: C11B13/04
Filed: 1950-03-25
Abstract: Oils, fats and waxes are recovered from earthy absorbent materials, such as Fuller's earth, used in refining them, by heating the absorbent material at atmospheric pressure, in the presence of a detergent, with an aqueous solution of an alkali, or an alkali-metal salt which reacts alkaline to phenolphthalein or a combination of these, the amount of alkali, alkali-metal salt or combination thereof being sufficient to react with the absorbent material, and removing the separated oil, fat or wax from the mixture.  The alkali or alkali-metal salt reacts completely with the reactive metallic constituents of the earth to alter its nature so that it is no longer capable of absorbing oily matter. The detergent may be a synthetic detergent or a soap.  The latter may be formed in situ by partial saponification of fatty oil or free fatty acid contained in the earthy absorbent material.  The alkalies or alkali-metal salts preferred comprise sodium carbonate or caustic soda.  The alkali or alkali-metal salts is usually present in amount less than 10 per cent. of the weight of the earthy absorbent material.  In the case of saponifiable oils using caustic soda, the calculated quantity of alkali is added at 60 DEG C. until disintegration of the abosrbent is complete and in the presence of water in amount from 2 to 4 times the weight of earth, followed by the addition of a further quantity of the alkali sufficient to produce the necessary soap to cause separation of the oil whilst the temperature is raised to 100 DEG C. The soapy liquor is drawn off and acidified to recover its fatty content. In examples, the treated earths contain viscous lubricating oil, tallow, lard, cod liver oil and rape oil.

Abstract: 684,065. Electromagnetic interrupters. GENERAL RAILWAY SIGNAL CO. April 3, 1951 [April 13, 1950], No. 7701/51. Class 38 (v) [Also in Group XXXVIII] A code signalling system (see Group XXXVIII) employs local balance-wheel oscillators to drive relay distributers. As shown, the energization of a U-shaped magnet 34-36 holds an armature 37 against non-magnetic stops 40, stressing a spiral spring 32. When the magnet is released, the armature oscillates, alternately operating and releasing two sets of contacts 41, 42, 45, 46 and 43, 44, 47, 48 by means of a cam 49. In the system described, four complete oscillations take place on each release of the magnet. In a modification, Fig. 16 (not shown) with a heavier moving system and a heavier spring, the non-magnetic stops are secured by magnetic screws and washers, and this enables the attracted position of the armature to be along the centre line between the pole pieces. In this construction, the weight associated with the armature is not secured directly to the shaft but is coupled to it frictionally and by means of a spring to avoid damage when the armature hits the stops.

Abstract: 673,957. Phase measurement. MINISTER OF SUPPLY, MILLER, C. W., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. March 15, 1950 [March 22, 1949], No. 7815/49. Class 37. [Also in Groups XXXV and XL (c)] An electrical wave-guide arrangement interconnecting two separate radio frequency sources and a load circuit so arranged as to prevent transmission of power between the sources but to combine the power outputs in the load circuit, comprises means for controlling the relative phasing of the two sources, said means being controlled by the voltages at two pick-up points which are so chosen that when the radio frequency inputs vary from the required phase relationship the ratio of the pick-up voltages varies from a normal ratio, said variation tending to restore the phase relationship of the power sources to the required value. Fig. 1 shows two sources A and B, which are combined to feed a load D by means of a ratrace wave-guide junction comprising rectangular guides 1... 4 supporting H 01  mode waves and forming E-plane T junctions spaced around a wave-guide loop as shown. Power fed into arm 1 and arm 2 is supplied to arms 3 and 4, with no coupling between arms 1 and 2, arm 4 being terminated by a dummy load C, and when the powers from A and B are equal and combined in phase in the load D connected to arm 3, no resultant power is fed to arm 4. Two pick-up points 5 and 6 provided by probes, loops, or series arms are located symmetrically about arm 4 and respectively feed two detectors which are connected to a differential circuit 8, an output being provided from 8 proportional to the phase difference between the two inputs which is utilized in known manner to control the phase shifter 7 to reduce the phase difference. The arrangement may be used with the travelling-wave linear accelerator employing feed-back described in Specification 664,906, [Group XL (b)]. In a modification, Fig. 3, a rat-race junction combines the sources A and B to feed the load D and arm 4 feeds a dummy load as before. Arm 1<SP>1</SP> of a similar rat-race junction is coupled to arm 1, and arm 21 is coupled through 90 degrees phase-shifting element 9 to the arm 2. Detectors mounted in the arms 31, 4<SP>1</SP>, feed a differential circuit 81, which provides an output dependent on the phase relationship between the waves in arms 1<SP>1</SP> and 21 to control the phase shifter 7. A magic T-junction may be used instead of a rat-race, the load being connected to the H-plane junction, the two power sources to the in-line arms, and the dummy load to the E- plane branch. If separated pick-up points are required, as in Fig. 1, the E-plane branch may be divided into two sections by a septum a half wavelength in length suitable pick-up elements being located one on each side of the septum. Specification 667,290, [Group XL (b)], also is referred to.
