Title: Sundial showing local or greenwich mean time
IPC: G04B49/02
Filed: 1923-02-16
Abstract: 214,034. Chase, L. H. Feb. 16, 1923. Sun-dials. - Greenwich mean time is read on a sun-dial by means of a director OP adjustably fixed to a rotatable disc H and having a curve, Fig. 2, marked on the vane 0, on which curve the image of the aperture Q is brought before reading time on the scale A against the pointer K. The disc H is graduated in intervals of 14‹ 22¢ and reads as a vernier against the 15‹ graduations on the fixed plate A, the reading being the nearest hour to the pointer plus or minus the minutes marked on the vernier at the coincident marks of the two scales. The displacement of the image right or left from the median line R when the pointer is at mean time is d tan #, d being the distance between Q and 0 and # being the angle in degrees corresponding to the equation of time. The value of # is obtained by multiplying the difference of time in minutes by 4. The displacement above or below the equinoctional position S due to declination is arrived at by multiplying the tangent of the angle of declination by d. The curve constructed from these displacement values is marked in months and provided with arrows showing the direction of motion. The director may be adjusted by a scale and pointer N for reading summer time. The position of the director pivot I on the disc may be varied. The equatorial plate A is adjustably connected to the fixed plate B by hinges C and telescopic arms D, graduations E being provided for different latitudes if desired. A lens may be fitted in the hole Q to give a brighter image, the focal length of the lens being the average distance Q to R. The director vane 0 may be curved and the diagram correspondingly modified.

Abstract: 804,666. Aerials; aerial couplings. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Feb. 15, 1956 [Feb. 16, 1955No. 4608/55. Addition to 704,659. Class 40 (7). An aircraft aerial system makes use of the metal skin of an aircraft member, such as a wing, as the aerial element and this is tuned and coupled to a transducer by means of a recess having a width equal or greater than its depth and conductive internal surfaces formed in a convex surface of the member. The recess contains means coupling it to a feeder and has a conductor or conductors arranged across its mouth and connecting a capacitor along the direction of flow of the radio-frequency currents. The dimensions of the recess and the value of the capacitor are chosen so as to tune the aerial system to frequencies within a required band. In one embodiment the recess 3 is formed in the leading edge of an aircraft wing 2 close to the fuselage 1. A coupling coil 4 is arranged in the recess and has a variable capacitor 7 connected across it for tuning purposes. The coaxial feeder has its inner conductor joined to the coil at an intermediate point 6 providing suitable matching and its outer conductor is earthed close to the point 30 at which the earthy side of the coil is connected to the side wall of the recess. A copper conductor 8 and capacitor 9 are connected across the mouth of the recess which may be protected by a non- conductive plastic sheet fairing 10. In a modification (Fig. 4) the tuned coil 4 is omitted and the inner conductor of the feeder led to a point 11 chosen so as to match the aerial to the feeder at a given operating frequency. In a more complex arrangement the feeder may be terminated at a switch on the side wall of the recess so arranged that the central conductor may be connected as required to any one of a number of extension wires connected to differing points 11 to provide proper matching at differing frequencies (Fig. 3, not shown). The capacitor 9 may be moved away from the recess and coupled to the side wall of the recess and the conductor 8 by a coaxial line; further, the conductor 8 may be made inductive by forming it as a coil. More than one recess may be provided to produce particular radiation patterns and the aerial may be formed from the tail fin or tail plane instead of a wing.

Title: Improvements in temperature-responsive control apparatus
IPC: F25D21/00
Filed: 1952-02-25
Abstract: 699,946. Thermal switches. RANCO, Inc. Feb. 25, 1952 [March 28, 1951 No. 4916/52. Class 38 (v) [Also in Group XXIX] A control apparatus particularly for the control of the defrost cycle of a refrigerator, comprises a switch 11, a reciprocable actuating member 40 slidably guided in openings 37, 35 in the walls 28, 30 of a housing 10, means such as a notch 46 on the member 40 co-operating with the edge 47 of the opening 37 to restrain the movement of the member 40 under the bias of a spring 42, and temperature responsive means to move the actuating member 40 to disengage the notch 46 from the edge 47 to permit the spring to restore the actuating member to the position shown. In use, the manual actuation of the member 40 to the right causes a cam formation 41 on it to actuate the snap-action switch mechanism 11 to initiate the defrosting. The notch 46 positively engages with the edge 47 due to the slight downward bias of the spring 42 on the member 40 to which the spring is secured by means of a downwardly projecting spur 43 on the member 40. At the end of the defrost period, fluid in a pipe 51, which is in heat exchange relationship with the evaporator of the refrigerator, expands a capsule 50 sufficiently for it to turn a lever 53 about a pivot 54. The end 57 of the lever 53 abuts and raises the member 40 slightly to disengage the notch 46 from the edge 47, whereupon the spring 42 restores the member 40 to its initial position and the switch 11 retracts to stop the defrosting action. The temperature in the evaporator at which this occurs is determined by the adjustment of a spring 60 which biases the lever 53 against the capsule 50.

Title: Disc brakes
IPC: F16D65/00
Filed: 1978-02-07
Abstract: The rotating brake housing of the full-lining disc brake contains two brake discs (92, 96) and a casing (90). The casing (90) rests by one end against the inside of one brake disc (92) and, with its other end, the casing (90) overlaps the outer circumference of the other brake disc (96). This is accomplished by means of a radially inward-projecting annular flange (98). The annular flange (98) is connected to the outside of the brake disc (96) by means of fastening screws. For fastening the casing (90) to one brake disc (92) use is made of clamping screws (104) and to the other brake disc (96) of the fastening screws. By virtue of this design, all that is now necessary for changing the linings is to release the clamping screws (104) connecting the casing (90) to the brake discs (92, 96) and it is no longer necessary to displace the brake discs (92, 96) from their installation position. <IMAGE>

Patent GB-918044-A (GB)
Title: Production of nuclear fuels, moderators or control members
IPC: G21C21/18
Filed: 1959-02-13
Abstract: Material for use as a nuclear fuel, a moderator or a control-rod is made by mixing the corresponding nuclear fuel, moderator or absorber material, in finely-divided state, with a metallic constituent comprising one or more metals, also finely divided, the mixture being sintered in an atmosphere containing hydrogen, a halogen and a chromium halide, the surface layer formed being substantially purely metallic.  The metallic constituent comprises one or more of the following: Fe, Ni, Co, Cr, Mo and alloys containing at least one of these metals.  The nuclear fuel, moderator or absorber material must have a heat of formation, if a compound, high enough to prevent it being reduced by the metallic constituent during the sintering operation and form halides which are both stable and volatile under sintering conditions.  The nuclear fuel may be UO2, U3O8, ThO2 or mixtures of these and may be mixed with a finely-divided moderator substance such as BeO.  The absorber material may be boron.  The sintering atmosphere may either be an atmosphere of hydrogen- and halogen-containing gas, e.g. a hydrogen halide which is dissociated at the temperatures employed, together with a chromium halide; or an atmosphere of hydrogen and halogen (as above) which forms chromium halide in situ, e.g. when the body to be sintered is packed in chromium fragments.  The halogen in the sintering atmosphere is preferably fluorine.  The metallic surface layer is plastic as well as being firmly bonded to the underlying matrix so that recompressions e.g. between two sintering stages, can be applied as on a press or in extruding and wire-drawing equipment without the risk of cracking.  When U3O8 is used, a reduction to UO2 may occur under some operating conditions with the formation of Cr2O3, if chromium is present in the matrix, and this may result in a hardening of the matrix.  Various oxides, e.g. Fe2O3, CeO, NgO and Al2O3 may be added to a UO2-containing mixture and during the sintering release oxygen which forms Cr2O3 in situ to harden the matrix. The mixture, prior to sintering, may be shaped and coated with a layer of Cr powder, an Fe-Cr alloy powder or a Cr-Ni alloy powder. A sheath of refractory material may be bonded to the metallic surface layer of the sintered material.  Many examples of processes according to the invention are given.  The Mo and Fe constituents may be present as fibres and Cd and W powders may also be added to the matrix.  Uranium carbide may also be used.

Title: Process for the production of aminocarboxylic acid amides acylated or sulphonated atthe nitrogen atom of the amino group
Filed: 1953-02-25
Abstract: Amino carboxylic acid amides acylated or sulphonated at the amino nitrogen atom are produced by contacting N-acylated or sulphonated chloramines with aqueous ammonia and sulphur or with an ammonium polysulphide solution at 100-300 DEG , preferably 150-180 DEG  C. The reaction is preferably effected in the presence of an inert organic diluent or solvent, e.g. alcohols, dioxane, hydrocarbons, ether or pyridine.  The reaction time is from 1 to 20, preferably 2 to 6 hours.  About 2-20, preferably 4-8 parts by weight of ammonium polysulphide solution, are used per part by weight of starting material and the reaction solution generally contains 5-20 mols. ammonia, 0.1-5 mols. hydrogen sulphide and 1-10 gram atoms of sulphur per litre.  The reaction is preferably effected in a closed vessel of steel, glass, porcelain or other resistant material.  The pressure developing in the vessel is about 5-40 kilos/sq. cm., although higher pressures are obtained when gaseous ammonia is passed in under pressure.  The products are obtained by evaporating the reaction solution to dryness and extracting with hot water.  In examples: (1) and (2) d -benzamino-n-valeric acid amide is produced from N-(e -chlor-n-amyl)-benzamide; (3) e -benzamino-n-caproic acid amide is produced from chlorinated N-n-hexyl-benzamide; (4) d -p-toluene sulphamino-n-valeric acid amide is produced from N-(e -n-chlor-n-amyl)-p-toluene sulphonamide; (6) e -p-toluene sulphamino-n-caproic acid amide is produced from chlorinated - N - n - hexyl - p - toluene sulphonamide.

Filed: 1943-04-02
Abstract: 566,089. Lasting-machines. BRITISH UNITED SHOE MACHINERY CO., Ltd. (United Shoe Machinery Corporation). April 2, 1943, No. 5275. [Class 17 (i)] A machine of the kind described in Specification 520,194 is provided with a retarder device, arranged to clamp the part of the upper pulled by the gripping means against the wip - ing means, to exercise a control on the upper in the course of the wiping operation. The device is actuated by fluid pressure. The shoe is positioned by a member 2 engaging the bottom face of the insole and the inner 'face of the lip of the insole, the member being interchangeably carried by a rod 6 vertically adjustable by a hand wheel 10. The rod 6 carries a cylinder 48 to which is pivoted a rod 34 carrying the retarder 24. The retarder is pivoted at 28 to a flat spring 30 screwed at 32 to the rod 34 and restrained by a guide 36 secured to the rod. The rod 34 also carries pins 46 engaging angular slots 44 so that the retarder is swung forwardly as it commences to descend. The cylinder 48 is urged upwardly by springs 60 and slides on a piston 52 to the underside of which oil under pressure is delivered by a pipe 70 when a valve 74 is swung by a cam to admit fluid thereto from a pressure pipe 78. The pressure on the retarder is determined by a spring 136 adjustable by a screw 144. The ends of the retarder first engage the upper, the retarder tipping about the pivot 28 to equalize the pressure on its two sides, the spring being bowed to permit the central part of the retarder also to clamp the upper. The retarder is lifted as the wipers rise to upwipe. Near the end of this movement the grippers release the upper. The valve 74 is actuated and the retarder is raised by its springs 60 before the wipers complete their over-wiping movement. To prevent oil dropping on the shoe, a groove 150 in the cylinder 48 communicates with a pipe 152 by which oil returns to the sump. Specification 556,240 also is referred to.
