Abstract: 426,106. Sirens. EKMAN, O. I. H., 64, Malmskillnadsgatan, Stockholm. June 23, 1934, No. 18640. [Class 13] A siren, Figs. 1 and 2, comprises a rotor carried by the motor shaft 2 and comprising a circular disc 3 having on its upper side a number of radial blades 30 situated between the hub of the disc and a peripheral flange formed with a series of sound apertures 31. The wheel 3 is surrounded by a stator 32 similarly formed with a series of apertures 33 and the stator is surrounded by a rotatable wall 7 having two diametrically opposite openings each of which is associated with a horn 13. The wall 7 with openings 34 in its upper end is rotatably mounted on the shaft 2 and may be driven mechanically, electrically or automatically. The rotation of the wall may be controlled by a spring 35 bearing against the stator and controlled by a screw 36. According to a modification, Fig. 3, (not shown); the wall instead of fitting the stator closely may be formed with diffused channels like those of a centrifugal pump. Fig. 4 shows a further modification in which the stator is dispensed with and the wall 7 which immediately surrounds the rotor 3 is provided with a single horn, the opposite side of the wall being counterbalanced by a blade-shaped projection 14.

Abstract: 810,219. Corrugating ; stamping screwthreads. KEELAVITE CO. Ltd. June 5, 1957 [June 15, 1955; Nov. 13, 1956; April 18, 1957], Nos. 18699/56, 34744/56 and 12810/57. Class 83 (4). Apparatus for forming one or more swellings 13 adjacent to the end of a pipe 11 by expanding it into one or more recesses 33 in a surrounding part or former 30, comprises a pressure-applying element 39 including a cylindrical head 40 for insertion into the pipe and carrying circumferentially extending sealing means including spaced annular end portions 46, e.g. of rubber, arranged to make fluid-right joints with the head and a tubular resilient membrane 47, e.g. of rubber, extending between and in fluid-tight engagement with the said end portions, and passages 41 and 43 by which fluid under pressure can be delivered to the periphery of the head surrounded by the membrane to expand the membrane and force the pipe into the said recess or recesses. Adjacent the recess 33 in the split former 30 is machined a cylindrical portion 35 larger than the pipe diameter and tapering at 36 into the former bore 32. Recesses 49 are provided on each side of the grooves 45 accommodating the sealing members 46 remote from the membrane to house tapered nylon buttress rings 50 which partly overlap the members 46. In operation, the application of fluid pressure forms the swelling or corrugation 13 in the pipe and also expands the pipe in the region of the cylindrical portion 35 of the former to form an accurate seating surface 18 for an O-ring seal 19 (Fig. 2). The buttress rings 50 are forced into engagement with the bore of the pipe during the expanding operation and prevent extrusion of the sealing members 46 into the space between the head and the pipe. The recess 33 may be circumferentially incomplete or may consist of a series or recesses arranged to co-operate with an internally-slotted part in the manner of a bayonet joint. Alternatively the swelling may be in the form of a screw thread to co-operate with a corresponding screw-thread in a secondary part, e.g. a co-operating pipe connection. Specification 770,532 is referred to.

Abstract: 1464926 Multi-disc brakes; spring-applied brakes; hydraulic systems; preventing vibration LAMBERT BRAKE CORP 1 May 1974 [26 June 1973] 19070/74 Headings F2E and F2F A spring applied, hydraulically released multidisc brake 2 comprises a plurality of rotor discs 44 axially movable on and rotatable with a rotor 26, and a plurality of rotationally fixed stator discs 60, 62 interleaved with said rotor discs 44 and axially slidable on torque pins 65, 67; a first stator disc 62 is engaged by a plurality of springs 83 which act to bias the assembly of discs into a brake engaged position and the assembly is movable into a brake released position by the action of hydraulic pressure on an annular piston 52 which piston 52 has an annular skirt 56 which surrounds the rotor discs 44 and engages the stator disc 62. The stator discs 60, 62 all have diametrically opposed ears 66, 68 formed with holes 76 to receive the torque pins 65, 67 and the ears 66, 68 of the discs 60 extend with clearance through slots 70, 72 in the piston skirt 56 while the ears 66, 68 of stator disc 62 do not project through the slots but are in axial alignment therewith and the stator disc 62 is in peripheral engagement with the skirt 56. Coil springs 78 mounted on the torque pins 65, 67 locate the stator discs 60, 62 and in combination with the springs 83 reduce vibration and noise. The rotor discs 44 are provided with friction material 46 which may be in the form of segments with radial grooves (48). To release the brake from its engaged position hydraulic fluid is supplied to an annular chamber 50 formed in a pressure plate 10 of the brake 2 whereby piston 52 is moved in the direction of disc 62 and in opposition to the force of springs 83 whereby the pressure on the discs is relieved and rotor 26 can be driven. An end wall 80 with a shoulder 86 that limits axial movement of disc 62. Hydraulic -fluid is introduced into chamber 50 via a conduit 88 threaded into a hole (90) in plate 10 and the plate 10 may have another hole 92 for receiving a screw-type bleeder valve 92. The brake 2 is interposed between a driving unit such as an hydraulic motor 4 and a driven unit such as a gear-box 6. As shown the rotor 26 is splined to an output shaft 30 of the motor 4 and to an input shaft 36 of the gear-box 6. Fig. 5 illustrates an hydraulic system for use with such an arrangement and comprising a fixed pressure pump P2 and a variable pressure pump P1. The pump P2 maintains a charge pressure for the system and supplies the necessary pressure through conduit 88 to release the brake. Pump P1 produces an operating pressure to drive the motor 4. The operating pressure is supplied through conduit 96 and returns through conduit 98 which is at charge pressure as a result of check valve 100. Check valve 102 prevents high pressure from conduit 96 from entering the charge pressure line. The brake may be used in various applications such as in vehicle power trains, machine tools, cable reels, and servo mechanism type applications.

Title: Improved bronze powders and manufacturing process therefor
Inventor: HALBERSTADT JOSEPH
IPC: C09C1/66
Filed: 1951-08-22
Abstract: The particles of a copper base bronze flake powder, e.g. for use in paints, are free from solvent soluble organic matter and coated with an invisible film impermeable to fumes and vapours likely to cause tarnishing.  Commercial powders manufactured by disintegration in hammer and ball mills in the presence of a suitable fatty lubricant, e.g. stearic acid, retain a small amount of this lubricant, usually about 0.5 per cent.  This lubricant is changed into a protective film surrounding each particle by heating the powder in an atmosphere having no decarburizing properties.  Suitable atmospheres are provided by hydrocarbon gases, e.g. methane or propane. Alternatively an inert gas may be used.  The temperature used is between 300 DEG C and the sintering temperature of the powder and is usually about 500 DEG C.  To increase the thickness of the protective layer the lubricant may be supplemented by the addition of more lubricant or other organic substances of which examples are given. The increase may also be effected by using acetylene as the processing atmosphere. p
