Title: Improvements in electric switches
IPC: H01H27/10
Filed: 1919-08-18
Abstract: 150,523. Newey, C. F. Aug. 18, 1919. No Patent granted (Sealing fee not paid). Secret combination switches for preventing unauthorized closure of motor-car ignition circuits and like purposes. The switch is composed of an insulating-base 1, on the visible side of which are mounted several numbered dials, provided with movable pointers 5 attached to knobs 6. The spindles of the knobs pass through the base and carry radial arms 7 which terminate in contacts adapted to engage stationary contact 8 mounted on the underside of the base. The electric circuit between a pair of terminals 11, 12 is thus completed when all the pointers are set in given positions. The combinations can be altered by removing the base and loosening nuts which attach the radial contact arms to the spindles. Reference has been directed by the Comptroller to Specification 136,759.

Title: Wave guide assemblies
IPC: H01P5/12
Filed: 1946-08-29
Abstract: 669,516. Wave-guides. WATSON, W. H., and GUPTILL, E. W. Aug. 29, 1946 [Sept. 19, 1945], No. 20372/50. Divided out of 669,463. Class 40 (viii). In a wave - guide assembly whereby energy is transferred from a feeder guide to a plurality of auxiliary guides, particularly for supplying energy to a two - dimensional slot aerial array as described in the parent Specification (see Group XL (c)), the feeder guide is coupled to each auxiliary guide by means of a slot common to the two guides and so dimensioned that in the impedance transformation from one guide to the other, the slot itself introduces no reactive components. Fig. 3 illustrates a system wherein the coupling slot 72 is coupled in series aspect (i.e. it behaves as a series impedance) in both guides, being more strongly coupled to the auxiliary guide B than to the feeder guide A. The Specification also illustrates several other arrangements including some where the slot is in shunt aspect to both guide and some where it is in series aspect to one guide and in series aspect to the other.

Patent GB-572249-A (GB)
Title: Improvements in door operation
IPC: E05F15/04
Filed: 1943-12-07
Abstract: 572,249. Door-operating a p p l i a n c e s. NATIONAL PNEUMATIC CO. Dec. 7, 1943, No. 20445. Convention date, March 30. [Class 65 (i)] To start the opening of a door, which opening is completed manually, compressed air is released from the left-hand side of a piston 39, in a differential-pressure engine, whereon compressed air trapped in a space 381 and between the pistons 36, 39 causes the piston 39 to move to the left and actuate linkage 5, 6, 7, through rack and pinion gear, to open the door 1 a few inches. The supply of compressed air from a pipe 11 passes through a strainer 13 and needle valve 15 to a valve 10 which is solenoid operated. When hand pressure is applied to a hinged panel 19, the solenoid is energised, the valve 10 cuts the connection between 11 and 16 and opens the pipe 16 to exhaust, releasing the compressed air in the cylinder 22. A handle 21 on the other side of the door, is coupled to the panel 19. When a valve 47 approaches its seat 48, compressed air passes out through a passage 49, the resistance having a retarding effect on the door movement. When the valve 47 bears on its seat 48, final movement of the piston assembly compresses a spring 41, which acts as a shock absorber during the termination of the door-opening movement. When the panel 19, or handle 21, are free, the solenoid is deenergised and compressed air flows through an inlet 26 from the pipe 16 and, at first enters the cylinder 22 only through the passage 49 and past a ball valve 43, into the spring chamber C and through the annular passage between parts 39 and 40. Valve 47 then opens allowing air direct entry into the cylinder 22. Compressed air from 22 seeps past a packing leather 38 into the storage space 381 The cushioning mechanism, i.e., the parts 40, 41, 43 may be dispensed with.

Title: A process for the manufacture of liver extracts from livers of fishes of the shark variety
IPC: A61K31/00
Filed: 1945-08-09
Abstract: Liver extract, suitable for oral and/or parenteral administration and derived from the livers of fish of the shark family, is prepared by subjecting the livers to pressure and/or extracting them with acidulated water to obtain a liquor the pH of which is adjusted, if necessary, so that on heating coagulated protein and tissue material separate therefrom and the coagulated material and oil are removed by methods known to be capable of producing a clear oil-free liver extract.  The livers may be (a) minced, macerated with acidulated water of pH 4.5 for 12 to 18 hours, (b) minced, the pulp mixed with sand, pressed, resoaked in water and again pressed, the liquor so formed being adjusted, if necessary, to a pH of 4.5 and the mixture heated to 80 DEG C. the oil floated off, the residue centrifugal and concentrated in vacuo at a temperature not exceeding 60 DEG F. to provide a liquor (A) which is worked up into preparations suitable for patenteral or oral administration.  In the former case, the liquor (A) is extracted with ether to remove residual fat, 90 per cent alcohol is added to produce 70 per cent alcohol in the mixture, the inactive precipitate removed, the clear liquor so formed further concentrated and absolute alcohol added to produce a 90 per cent alcohol mixture, the precipitated active material being dissolved in sterile distilled water containing phenol, filtered through a bacteria proof filter and ampouled.  For oral administration the liquor (A) is concentrated in vacus to a syrupy consistency, residual oil removed by ether extraction, and suitably diluted used as such with, if desired, the further addition of glycerin or alcohol and suitable flavours.

Title: Process for extracting iron from oxidic ferrous ores
Inventor: HEITMANN GUNTER
IPC: C21B13/14
Filed: 1967-05-03
Abstract: Oxidic iron ores are given a preliminary reduction in a rotary kiln with a solid carbonaceous reducing agent having a high content of rotable matter and are then finally reduced in an electric furnace, the whole of the reducing agent required for the reduction and for carburization of the product being fed by mechanical and/or pneumatic into the kiln from the solids discharge end thereof in such a manner that the reducing agent is distributed over the surface of the charge for at least 4 metres of the kiln length.  The desired distribution may be effected ballistically by using a reducing agent having a wide particle size range, or by using a multiplicity of feed pipes inclined at varying angles to the kiln axis and/or provided with differing propelling forces.  Fine particles of ore be separated prior to charging, and added to the kiln with the reducing agent.
Patent GB-700948-A (GB)
Title: Improvements in or relating to whirling machines for coating lithographic plates
Inventor: KOELLNER WALTER
IPC: G03F7/16
Filed: 1951-08-31
Abstract: <PICT:0700948/III/1> <PICT:0700948/III/2> For coating lithographic plates, a whirling machine comprises a plate support, a D.C. electric shunt motor arranged for connection with a mains source of alternating electric current and connected with the plate support to effect rotation thereof, rectifying means in the armature and field circuits of the motor, and a variable transformer included either in the armature or the field circuit between the rectifying means therein and the mains source of current supply whereby a selected constant speed of rotation of the support can be obtained.  The machine has a plate support 1, Fig. 1, mounted on a spindle 2 connected to the shaft of a D.C. shunt motor 3.  Current for the motor field F, Fig. 2, is supplied from an A.C. supply through a main switch 4 and a two-way metal rectifier 10.  Current for the motor armature A comes from the same supply and passes through a relay 13, a variable transformer 14, built on the auto-transformer principle, and a metal rectifier 15.  When the motor is started the main switch 4 and a secondary switch 17 are closed whereupon current is supplied to the motor field F.  Current also passes to the relay 13 along lines 18 and 19 through a closed micro-switch 16, causing relay contacts 13b and 13c to close, and 13a to open.  As a result current is passed to the transformer 14 along lines 5 and 20, so that on movement of the control knob of the transformer from the zero position thereof current is supplied to the armature field A through lines 21 and 22.  The speed of the motor is determined by the extent to which the transformer control knob is adjusted. Movement of the control knob from its zero setting opens the micro-switch 16 so that supply to the motor continues as described until one or both of switches 4 and 17 is or are opened, or until the transformer setting is restored to zero.  Braking is effected on setting the transformer to zero either by opening switches 17 or 4 or by the action of the micro-switch 16, which, of switches 4 and 17 remain closed, short circuits relay 13.  In each event the relay contacts are reversed so that 13a is closed and 13b and 13c are open.  Closing of 13a effects braking by short circuiting the armature field along lines 25 and 26. If desired the transformer may be in the field circuit, but its position in the armature circuit is preferable.

The cover for the universal joint comprises two part-spherical rigid members 12 each having a series of outturned lugs 15 which inter-engage to provide means for securing the two members together by a spring ring 17. A resilient ring 18 may be fitted over the joint to form an oil-tight casing. The ends of the members 12 remote from the lugs 15 are outturned to receive a thickened end of the flexible housing member 20, the other end of which is fastened to one part of the universal joint by a thickened end 25 secured by a circlip 26, and may be protected by a shroud 27. Modifications are described in which the flexible ring is out-turned to provide the double-walled portion. Where the two shafts have only relative angular movement, the whole cover may be moulded in rubber with thick and thin portions for the rigid and flexible parts respectively. The two housings 12 may be secured together by a circlip, laced by a spring or held by a series of spring loops.

Abstract: 754,174. Valve gear. EATON MANUFACTURING CO. July 20, 1954 [Jan. 20, 1954], No. 21119/54. Class 7(6) A clearance adjusting mechanism comprises a pair of screw-threaded members 31, 32 which are biased apart by a torsion spring 38, the member 32 being in frictional engagement with a push rod member 30 which is oscillated on each valve cycle by a sleeve 45 fixed thereon actuated by a stationary cam 42. The lower end 34 of the member 32 fits within the bore of the push rod 30 and carries a flange 36 which is in frictional engagement with the top of the push rod 30, the member 31 having a socket 27 which is in frictional engagement with an adjustable setting screw 25 carried by the valve rocker 22. The sleeve 45 comprises a wire coil fitting tightly on the rod 30 one end 48 of which coil is anchored in a hole 46 in the member 30 and engages a groove 47 in the member 32 to hold it in position and the other end 43 of which is extended to form an arm co-operating with the cam 42. On each downstroke of the push rod, the cam 42 moves the arm 43 to tighten the coil 45 and thereby rotates the rod 30 in the direction which causes screwing of the member 32 into the member 31 to shorten the push rod arrangement. When the valve 12 seats and the push rod arrangement is free of the load of the valve spring 18, the members 31, 32 are screwed apart by the torsion spring 38 until any clearance is taken up. On the upstroke of the push rod the load of the spring 18 prevents the members 31, 32 being screwed apart and the backward rotation of the rod 30 is not transmitted to the member 32, slipping occurring at the collar 36.

Filed: 1962-06-01
Abstract: 992,515. Resistors. MHOGLAS Ltd. May 21, 1963 [June 1, 1962], No. 21214/62. Heading H1S. A non-metallic electrical resistance element is made by forming a suspension in a liquid medium of substantially uniform size agglomerations of particles of graphite or other material of low conductivity, coating a fabric or fibres of inorganic material, e.g. glass, with the suspension, drying and, if necessary, treating the coated fabric or fibres to remove any organic matter, additives and impurities present in the coating. It is preferred that the agglomerations should have a diameter of about 2 to 3 microns. The suspension is prepared in one example from a colloidal suspension of 25% by wt. of graphite in water comprising 90% by wt. of the graphite in a truly colloidal state, i.e. 2 microns diameter or smaller, by diluting with four times its volume of water, a coagulant comprising ¢ to 1% by wt. of cationic soap dissolved in water calculated on the weight of the original suspension then being stirred into the suspension little by little. Thickening is observed and when thinning just begins due to a redispersal by the soap, no more soap is added and the mix is allowed to stand for an hour before being passed through a mechanical emulsifier set so that a microscopical examination shows the dispersion to be of a uniform particle size of about 3 microns or less. Specification 747,257 is referred to.
