Abstract: 679,453. Magnetic compositions. GENERAL ANILINE & FILM CORPORATION. May 7, 1951 [May 10, 1950], No. 10697/51. Class 38 (ii). A non-metallic ferromagnetic composition suitable for cores used at frequencies between 30 and 300 megacycles/sec. is made by heating between 850‹ and 1250‹ C. a dry powdered mixture of ferric oxide with one or more of nickel, copper or magnesium oxides in a molecular ratio between 2: 1 and 1: 2, and terminating the heat treatment when between 60 and 95 per cent of the iron and also of the other metal or metals in the composition remain undissolved after treatment with 6N aqueous HCl at 100‹ C. for 1 hour. Examples are described in which the other oxide is of nickel in the mol. ratio with the ferric oxide 1 : 0 to 1.4: 1, the oxides are ball milled together as a wet paste which is afterwards dried, then heated as a loose powder in air for 6 hours at 900‹-1200‹ C., e.g. at 1050‹ C., sieved and compressed with a binder. This may be a synthetic resin such as urea-, melamine-, furfural-, or phenol-formaldehyde or a polysiloxane resin, or an inorganic material such as a sodium or other alkali metal silicate. In an alternative method the powder may be moulded before heat treatment with a binder destroyed by heat. Values of G and Q are given which tests show to be stable against magnetic and mechanical shock. While the degree of conversion may be determined chemically by treatment with the 6N acid, it may also be controlled by observation of the degree of colour change in the composition.

Title: Improvements in lapping machine
IPC: B24B33/04
Filed: 1931-04-13
Abstract: 376,750. Grinding. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.-(Pratt & Whitney Co. ; Hartford, Connecticut, U.S.A.) April 13, 1931, No. 10881. [Class 60.] Rollers, spindles, and the like, treating.- A machine for lapping conical members of antifriction bearings &c. consists of three laps of part conical form rotating at different speeds and engaging the surface of the work at angularly spaced positions, the differences in the speeds of the laps causing the work to rotate at an intermediate speed. The machine comprises a base 10 having on its upper surface movable heads 11 supported by parallel links 13 carried by shafts 14, 15 in housings 12, so that the head may move towards and from the work W. Within the heads 11 and carried thereby, are electric motors 34 which drive through gearing, shafts 16, each carrying a cast-iron &c. lap 17 of frusto-conical form to which abrasive is applied. The work W is carried, so as to be capable of adjusting itself laterally, by a vertical shaft 18 rotatably mounted in a sleeve 19 movable axially to give the work a slight axial reciprocation by a lever 21 and a cam 23, the sleeve being supported by a spring 20, the tension of which is adjustable by a wheel 92 operated, through worm gearing, by a shaft 95 and hand-wheel 96. During lapping, the laps rest upon the work with a pressure due to the weight of the heads 11, and the heads are moved simultaneously away from and towards the work by the vertical movements of a rod 25 carrying lugs 26, 27 adapted to engage a pin on a bevel gear 24 on one of the shafts 14, which are geared together by other bevel gears 24 ; the lugs are separated so that they are free of the pin when the laps engage the work, by a lever 29, which lifts the lug 27 against the pressure of a spring 33. The rod 25 is lifted by a cam 80 carried by a shaft 52 which is driven at two different speeds from the shaft 36 of a motor 35, one speed being a direct drive through gearing 37, 40, 43, 45, bevel gears 46 carried freely in a yoke 47 on a worm wheel 41 and gearing 50, 51, and the second, and increased, speed being obtained by clutching a worm 38 to the shaft 36 and releasing a brake from the sleeve of the worm 38, whereby the wheel 41 rotates in the opposite direction to the wheel 40. The clutch and the brake are operated by a lever 72 actuated by dogs 75 on a disc 76 on the shaft 52. The work is removed and replaced by another work-piece during the period of increased speed of the shaft 52, and operation on a work-piece is completed in one rotation of the cam 80.

Title: Apparatus for securing a container to a base
IPC: B60P7/13
Filed: 1974-03-12
Abstract: 1455484 Twist-lock fasteners GRAUBREMSE GmbH 12 March 1974 [13 March 1973 28 Aug 1973] 10937/74 Heading E2B  The fastening bolt 6, 7 of a twist-lock container fastener is raised to a non-gripping position by fluid-pressure and returned to a gripping or retracted position by spring-pressure. In the form shown in Fig. 5a, the fastener is lifted by pneumatic piston 17 in cylinder 14, and returned flush with plate 11 or held in gripping position in a container fitting (not shown) by a spring 18. The fastener is rotatable in the piston at bearing 23 and it is rotated to an appropriate position, on axial movement, by lateral projections 26 engaging in partly spiral grooves 25 (Figs. 5c and 6, not shown). It is described (Fig. 7, not shown) how the fasteners may be operated simultaneously from a vehicle brake system. In the form shown in Fig. 8, the axial movement is produced by a helical surface 49 on a sleeve 46 having an arm 48 which is turned pneumatically against spring-pressure (Fig. 9, not shown). In a further embodiment, Fig. 10, the fastener 6, 7 is axially moved, against spring 18, by a piston 17 which is rotatable on it. The shank 6 of the fastener is hollow to house a stud 63 which is rotatably secured to the base 15 of the casing. A locking plunger 56 slides inside the shank 6 and is biased down by a weak spring 59. The stud 63 has square portions 64, 66 joined by a screw section 65 and it is normally held against rotation by lever 71. The base 67 of the shank 6 has a square hole to fit the stud so that it rotates 90‹ during axial displacement. Air pressure from line 32 lifts the piston 17 and also raises the locking plunger 56 against spring 59 so that shoulders 58 are lifted clear of balls 62 so that they clear slots 44 thus allowing the piston 17 to raise the shank and thus rotate it 90‹ as it passes section 65 of the stud 63 (Fig. 11 not shown). The container fitting can now be placed on the fastener. When the casing 14 is again exhausted, the fastener is pulled down and at the same time rotated to its fastening position. At the same time, the locking plunger 56 descends, forcing the balls out into the wide region 44 of the guide 43 to prevent upward movement of the fastener against its spring loading by excessive force. In an emergency, the fastener may be released by turning it by means of lever 71.

Title: Improvements in or relating to pressure-gas operated horns
Inventor: VRSALJKO DINKO
IPC: G10K9/04
Filed: 1964-03-16
Abstract: 1,025,549. Gas pressure horn. KOCKUMS MEKANISKA VERKSTADS A.B. March 16, 1964, No. 10948/64. Heading G5J. In a pressure-gas operated horn the flow of gas is periodically interrupted by a freely moving rigid disc-shaped valve member 12. The gas, supplied via the annular inlet 5, forces the valve off the seating 4 and 8 of which the seating 8 is considerably broader than the seating 4. The escape of gas down the trumpet forms a pressure wave and the subsequent decompression wave in the trumpet, the compression of the residual gas behind the valve and the weight of the valve itself all cause the valve to return to the seating and so recommence the cycle. The holes 15 and 16 in the chamber and valve disc respectively, allow the compressed gas behind the valve to leak away when the horn is not in use so that it may restart easily immediately after a prior sound emission. Annular grooves may be provided in the seat 8 and/or disc to improve the sealing between the valve and the seatings.

Abstract: 206,784. Thornton, A. A., (Motion Picture Improvement Co.). April 23, 1923. Testing-apparatus, auxiliary. - Comprises a device for correctly setting a number of lenses round the periphery of a disc, used in kinematograph apparatus of the continuously moving film type for the purpose of optical compensation of the movement of the film. The optical centre of each lens sector must lie on a common circle and the distances between the centres, must be equal. This adjustment is effected by mounting the disc J on a shaft F carried in journals e<2>, e<3> capable of rotation about the axis of a telescope formed by an eye-piece C and one of the lenses K. A second disc G on the shaft F is provided with a series of apertures g opposite the lenses K and notches g<1> on its periphery so that any selected lens map be held in the testing position. When testing the lenses, the disc J is first set so that the image of cross-lines on the target X formed by one of the lenses K coincides with the crosshairs c<1> in the telescope eyepiece. The shaft F is then rotated round the axis of the telescope on the bearings e, e<1> and the lens K adjusted until no movement of the image of the target results. Successive lenses in the series are similarly adjusted and when so adjusted in the disc J, the disc is ready for use in kinematograph apparatus.

Abstract: 865,541. Thermocouples. WESTINGHOUSE ELECTRIC CORPORATION. April 9, 1958 [April 16, 1957], No. 11202/58. Class 37. A thermocouple comprises one element consisting of a compound of the formula Li m A (1-m) B or Al n A (1-n) B where A represents one or more of the elements Mn, Fe, Co, Cu and Zn, B represents S, Se, Te or O, and m and n have values between 0.001 and 0.1. Preferred thermocouples utilize a member made of one of the compounds Li m A (1-m) B which have positive thermoelectric powers, connected to a member made of one of the compounds Al n A (1-n) B which have negative thermoelectric powers. Alternatively a member of Li m A (1-m) B may be used in combination with a member made of a compound MZ (1-a) , and a member Al n A (1-n) B used with a member made of a compound MZ (1+a) , where M is at least one element selected from Cr, Mn, Fe, Ni, Co, and. Cu, Z is at least one of the elements Se, Te, S, As, Sb, Bi and a has a value in the range 0.001 to 0.1. Such an arrangement used as a heat pump is shown in the Figure. The thermocouple members 12, 14 are joined within an insulated chamber by a strip 16 of copper or silver soldered to metal layers 18, 20, vacuum evaporated or ultrasonically brazed on the elements. The strip 16 and strips 22, 24 similarly soldered to the other ends of the elements outside the chamber may be finned to facilitate absorption and dissipation of heat. With the circuit shown, heat is absorbed at strip 16 and rejected at strips 22, 24. A number of such couples may be connected in series to increase the cooling effect. The couples may also be used as current generators by placing one set of junctions in a furnace and cooling the other set. Couples consisting of any of the compounds and a metal, e.g. copper, silver, copper alloys, silver alloys and molybdenum, are also useful. Materials of the formula MZ (1a)  specifically described are non-stoichiometric compounds of chromium or manganese with tellurium, arsenic, antimony or bismuth, e.g. manganese arsenide, telluride, bismuthide and antimonide and chromium telluride, which are made by intimately mixing the correct proportions of the elements, firing in a protective atmosphere and compressing and sintering the resulting powder. The compound Li .01 Zn .92 Cu .07 O is made by mixing suitable proportions of lithium peroxide, zinc oxide and cupric oxide, compressing, and heating in a sealed container to 900 C. for several hours. The resulting non-homogeneous mass is fused, and recrystallized by slowly withdrawing from a furnace to form a homogeneous, preferably monocrystalline body. A compound of the formula Al n Cu (1-n-p)  Zn p O may be made by heating an alloy of copper with 10 atomic per cent of aluminium in an oxidizing atmosphere and mixing the resulting oxide with a suitable amount of zinc oxide. The mixture is then melted and resolidified to a homogeneous mass. Specification 865,542 is referred to.
