Title: Improvements in or relating to lattice girders, framed structures or frameworks built up from metal elements
IPC: E04C3/293
Filed: 1940-03-26
Abstract: 540,018. Lattice girders roof trusses. ADAMS, J. E. March 26, 1940, No. 5463. [Classes 20 (ii) and 20 (iv)] In making light framed structures such as lattice girders and roof trusses the metal elements are assembled in their relative positions extending at each joint into or through a moulding box which is then filled with concrete. The moulds may be left permanently in position or may be removed after the concrete has set. The metal elements may be apertured, bent or otherwise shaped to provide an anchorage within the concrete. The moulds may be of sheet steel or of plastic material and are provided with slots for receiving the metal bars such as 2, 3, 4, Fig. 2, the tops of the slots being closed by a tension band 5 after the bars have been placed in position. When necessary the slots are made deep enough to take several parallel bars, which are separated by spacers. A lattice girder of the form shown in Fig. 6 has its joints J1, J2 made in the manner indicated in Figs. 7, 8, the ties 19 and struts 24 being formed with hooked ends and links 22, 28, 30 being placed around the parts to assist the anchorage. If desired the portions of the boom 18 between the joints may be encased in concrete. In the case of a roof truss of the form shown in Fig. 14, in which the rafter member R consists of a bar R1 encased in concrete, slotted moulds somewhat similar to that in Fig. 2 are employed, and the one at the joint J2 communicates with the shuttering about the bar R1. The invention is applicable also to structures involving threedimensional joints. Specifications 271,909, [Class 34 (i)], and 495,566 are referred to.
Patent GB-482686-A (GB)
Title: Method of and apparatus for electromagnetically controlling the output of air or gas compressors
IPC: F04B49/24
Filed: 1937-02-23
Abstract: 482,686. Regulating compressors. HOERBIGER, J. R., and HOERBIGER, A., (trading as HOERBIGER & CO.). Feb. 23, 1937, No. 5466. Convention date, Feb. 24, 1936. [Class 8 (i)] [Also in Group XXXV] The output of an air or gas compressor is controlled by adjusting the moment at which the spring - loaded suction valve closes during the discharge stroke of the piston. The suction, valve is acted upon in the direction of opening by an electromagnet 23 which is connected to the power lines through a switching device which comprises a plate 11 rotated at the same speed or half the speed of the compressor. A contact bridge is adjusted by hand or automatically and cooperates with discs 12, 13 arranged on the plate 11 to vary the point at which the current to the coil 23 is reversed. When the current is reversed the suction valve closes and the electromagnet is not powerful enough to open it against the compression then taking place in the cylinder. In a modification two coils are provided to a valve and the current flows through them alternately in opposite directions.
Patent GB-1448101-A (GB)
Title: Torque transmitting device with torque limiting brake
IPC: F16D67/02
Filed: 1973-02-03
Abstract: 1448101 Torque-limiting automatic brakes LUCAS INDUSTRIES Ltd 23 Jan 1974 [3 Feb 1973] 5466/73 Heading F2E A torque-transmitting and -limiting device comprises an input drive member 10, a coaxial output drive member 11, first and second coupling members 16, 17, through which torque is transmitted from input to output, pre-stressed torsion means 18 applying a torque load to the coupling members 16, 17, and a brake 12 to 15 actuatable on relative movement of the drive members 10, 11. (Fig. 2 is a continuation to the right of Fig. 1). As shown, the coupling members 16, 17, are generally tubular and are splined to the torsion bar 18 at opposite ends thereof. The torsion bar is pre-stressed by twisting the left-hand end counter-clockwise (in the sense of Fig. 3) relative to the right-hand end so that on assembly, lobes 16a, 16b on coupling member 16 are pressed into contact with the right-hand edge of keyways 19a, 19b at one end (where there is a cam 12) of input member 10, while fins 17a, 17b on coupling member 17 are partly accommodated in slots 21 between lobes 16a, 16b and are pressed into contact with the left-hand edge of keyways 19a, 19b. Keyways 20a, 20b at one end (where there is a roller cage 13) of output member 11 are normally aligned with keyways 19a, 19b respectively and are similarly engaged by the lobes and lugs. The coupling members are rotatable relative to the input and output members, while a fixed ring 15 surrounds an assembly of rollers 14 and the roller cage 13. In operation, on clockwise rotation (in the sense of Fig. 3) of input member 11, the drive path is as follows: keyways 19a, 19b, fins 17a, 17b on coupling member 17, torsion bar 18, coupling member 16, lobes 16a, 16b, keyways 20a, 20b of output member 11. When the transmitted torque tends to exceed preloading of bar 18, the edges of keyways 19a, 19b force fins 17a, 17b slightly clockwise, but since these keyways are integral with cam 12 it follows that cam 12 turns slightly clockwise relative to keyways 20a, 20b and thus to roller cage 13, thus jamming rollers 14 against fixed ring 15 and braking all moving parts. On counterclockwise rotation of input member 11, the drive path is: keyways 19a, 19b, lobes 16a, 16b on coupling member 16, torsion bar 18, coupling member 17, fins 17a, 17b, keyways 20a, 20b of output member 11. For excessive torque in this case, lobes 16a, 16b are forced slightly counter-clockwise, i.e. cam 12 turns slightly counter-clockwise so rollers 14 are again jammed.

Title: Titanium dioxide capacitor
IPC: H01G4/10
Filed: 1954-02-25
Abstract: 752,670. Metal surfaces treatment. ERIE RESISTOR CORPORATION. Feb. 25, 1954 [March 23, 1953], No. 5560/54. Class 82(2) [Also in Group XXXVI] A capacitor comprises titanium and silver electrodes 1, 2 separated by a dielectric layer 7 of titanium dioxide. The capacitor is prepared by coating the titanium sheet 1 with a layer of silver or a silver bearing composition and subsequently heating in an oxidizing atmosphere, the oxygen diffusing through the silver coating and oxidizing the titanium underneath. A layer 3 of gold or other noble metal impervious to oxygen is formed upon the titanium at the other end of the sheet 1 before it is heated. Leads (not shown) are soldered to the layers 2, 3. The layers 2, 3 may be prepared by evaporation of the appropriate metal on to the titanium sheet or by the application of a suitable paint which on heating breaks down to form a film of the desired metal. In the latter case, the oxidation step may be made part of or a continuation of the firing step. In a modification Fig. 3 (not shown), the coated titanium foil is initially loosely rolled into a cylindrical shape and subsequently oxidized to form a roll-type capacitor.

Title: Improvements relating to moulds for the casting of metals
Inventor: WESTWOOD ALBERT RONALD CLIFTON
IPC: B22C1/22
Filed: 1958-02-21
Abstract: Moulds, particularly for casting titanium, zirconium or alloys thereof, are made from graphite powder and a thermosetting synthetic resin, the resin being cured and then completely carbonized.  The resin is in sufficient quantity to leave behind, after carbonizing, an amount of carbon sufficient to bind the graphite particles together, but not so great that the evolution of volatile materials during carbonizing will weaken the mould structure.  In an example, the mix contains 40% of phenol formaldehyde resin, and is carbonized by baking at 850 DEG  C. for 1 1/2 hours in an argon atmosphere.  The facing-layer of the mould may be made by first coating the pattern with one or more layers of the mix made up into a slurry with a volatile liquid such as aliphatic alcohols, which is then driven off.

Title: Improvements in and relating to the sterilisation of liquids
IPC: A61L2/238
Filed: 1930-02-21
Abstract: 353,409. Purifying liquids. KRAUSE, G. A., 9, Bavariaring, Munich, Germany. Feb. 21, 1930, No. 5882. Convention date, March 1, 1929. [Class 46.] Liquids, especially water, are sterilized by adding thereto salts of oligodynamically active metals in small amount, not exceeding 2 mgms. of metal per litre, and leaving the liquid for sufficient time after the mixing to allow the sterilization to be completed before drawing it off for use. The time for which the liquid is held is longer as the amount of the salt added is decreased. Salts of silver, copper or mercury may be used. The metal may be removed and recovered from the treated liquid, e.g. by deposition on a grid or filter of a baser metal such as iron or aluminium, a corresponding amount of which goes into solution, or by absorption, or electrochemical means. Where water is sterilized and is then treated with lime, the presence of salts of iron and aluminium, when added by the metal-recovery step, will be of use in the coagulation process. The apparatus used in sterilizing must not contain a metal baser but may contain one the same as or nobler than that in the sterilizing salt. The apparatus may be constructed of glass, stoneware or other non-metallic material. The treatment may be combined with oligodynamic sterilization by the aid of a free metal which must not be less noble than that in the salt added. In the example given, water, which may have been filtered, flows in through a pipe a to a vessel d where a solution of the sterilizing salt, such as silver nitrate or copper sulphate, of known strength prepared in a vessel b is added in accurately measured quantity through a pipe c. The water then enters chamber f through which it takes three hours to flow, the chamber being subdivided by partitions or by fillers which may be coated with a suitable metal to increase the sterilizing action. The sterilized water passes to a vessel i which contains a grid or filter k formed of iron wire netting or iron clippings or turnings. The purified water leaving at l may be further treated with lime and filtered. The sterilizing salt may alternatively be added in solid form. Specification 325,796, [Class 46, Filtering &c.], is referred to.
