Abstract: 576,984. Interrupters. FORD MOTOR CO., Ltd. May 18, 1944, No. 9583. Convention date, May 17, 1943.

Abstract: 1445474 Moulded foamed olefine resin particles KANEGAPUCHI KAGAKU KOGYO KK 13 Dec 1973 [19 Dec 1972] 57776/73 Heading C3C Moulded foamed articles are made by (a) pressing pressurizing gas into foamed olefine resin particles having at least 65% of closed cells, based on total cell volume, the resin being cross-linked and having 0À1-70% of gel content (i.e. wt. per cent insolubles in xylene) so that pressurizing gas in the particles is kept at a pressure greater than 1À18 atm., (b) charging the particles into a mould, (c) heating the particles in the mould while maintaining the above pressure within them to cause their expansion and adhesion to form a moulded article and (d) releasing the article from the mould after allowing it to cool, e.g. to a temperature of less than its m.p. and not more than 50 C. lower than the m.p. The resin may be cross-linked by ionizing radiation or with a cross-linking agent. In the examples crosslinked polyethylene pellets were foamed, e.g. by impregnation with dichloro-difluoro-methane and then steam heating, the foamed pellets were allowed to stand in air and/or nitrogen, or carbon dioxide under pressure and then the pellets were placed in a mould which was steam heated to form a moulded article which was removed from the mould after water cooling thereof.

Title: A Shear-Type Viscous Liquid Coupling
Inventor: LUTZ OTTO
IPC: F16D35/02
Filed: 1967-12-22
Abstract: 1,168,440. Hydraulic couplings and control. O. LUTZ. 22 Dec., 1967 [24 Dec., 1966], No. 58385/67. Headings F2C, F2D and F2L. In a shear-type viscous fluid coupling, particularly for a motor vehicle cooling water fan drive, wherein an amount of liquid depending on the torque to be transmitted is circulated between invariably axially spaced annular coupling surfaces of a rotatable housing 3, 8 and a rotatable disc 2, the housing provides an annular chamber 5 radially outwardly of the disc 6 and large enough to receive the total amount of the liquid when centrifuged, from which annular chamber liquid is taken through a pipe 6, having a bent end 7 positioned in said annular chamber so as to extend contrary to the direction of housing rotation, and is fed to the coupling surfaces, at the inner peripheries thereof, through an externally controlled valve. As shown, the disc 2 is fast with a driving shaft 1 and positioned between one wall of the housing and a radially outwardly perforated disc 4 secured thereto. The housing is rotatably mounted on a stationary stub shaft 9. The pipe 6 is fast in the shaft 9 in which is axially mounted the control valve piston 10. The latter has an edge 11 controlling flow from the pipe 6 to a pipe 12 leading into a conical lip 14 of the disc 4. Alternatively, liquid flowing from the valve may be taken through a rotary connection to an axial bore of the shaft 1 from whence it may be directed through radial bores in said shaft. In order that the liquid flows to both sides of the disc 2, the latter is radially inwardly perforated at 13. When inoperative, the liquid collects at the lower part of the housing so as to partly wet the driving disc 2 and a starting torque is transmitted sufficiently to accelerate the housing and develop a ring of liquid in the chamber 5. The valve piston 10 may be controlled by a cooling water temperature responsive bellows 15 or an over-riding control member 18. The latter may be manually actuated, e.g. by an instrument panel knob, or electromagnetically actuated in response to manual or vehicle speed responsive control. In such electromagnetic actuation, the armature may be formed by the valve piston 10. A spring 20 protects the bellows 15 when the over-riding control is actuated. In Fig. 3 (not shown), the housing 3, 8 and the disc 2 are respectively driving and driven, the housing being, e.g., provided with a V-belt groove (24), and the pipe 6 rotates, being fast with a rotating shaft 1 which carries the disc 2 and houses the valve piston 10. The pipe 12 is replaced by radial ports (27) branching from an axial bore (26) in the shaft 1. Multiple intercalated discs 1, 4 may be provided.

Title: Stators for rotary electric machines
IPC: H02K1/06
Filed: 1973-12-17
Abstract: 1457450 Core constructions SKF INDUSTRIAL TRADING & DEVELOPMENT CO BV 17 Dec 1973 [21 Dec 1972] 58422/73 Heading H2A A stator for a rotary electric machine comprises a stack of laminations with faces parallel to the machine axis, whose edges parallel to the axis are bent inwards toward the stator bore to form the poles of the machine and are held in place by a moulded compound. The laminations 35 are previously bent and fitted with windings 32 and take up a radius D1 before fixing. The insertion of mandrel 34 deforms the laminations such that the edges form a cylindrical surface of radius D2. The mandrel may be ridged or grooved (Fig. 5, not shown) to guide the edges. A thermosetting resin 37 is then poured into the mould to secure the windings and laminations in place. A pole of highly accurate shape is thus provided ensuring a close tolerance air-gap and hence high efficiency. The laminated polepieces have the same sectional area as the yoke pieces 30 avoiding excessive core-losses and a smaller construction (Figs. 12a, 12b, not shown). The flux resistance of the magnetic circuit may be controlled by altering the lamination thickness to take account of the extra length of some laminations. Desired flux patterns are provided by adjusting the distribution of the lamination edges and by splitting the lamination edges (Figs. 7 and 10b, not shown). A shaded pole motor may be constructed by providing short circuited turns on some laminations (Fig. 8, not shown). In a modification (Fig. 11, not shown) the coils are wound on the yoke portions allowing a large surface area for cooling both inside and outside the motor.

Abstract: 1,202,759. Producing metal powder. SOC. DES ACCUMULATEURS FIXES ET DE TRACTION. Dec. 17, 1968 [Dec. 18, 1967], No. 59984/68. Heading C7D. Metal is produced in the form of agglomerated particles by precipitating particles of the metal from a solution of a salt of the metal by agitating a mixture of the salt and a reducing agent with a purturbed whirling motion, continuing the agitation to agglomerate the metal particles, separating said particles from the mother liquid, and washing and drying the agglomerated particles to obtain the desired powder. The agitation is obtained either by creating more than one vortex in the mixture or by purturbing a single vortex e.g. by use of an agitator comprising rotatable and stationary blades. The powders obtained may be compressed and sintered to form electrodes. Advantageously silver powder is produced by this method from AgNO3 reduced by Na2 SO3, and these two compounds are mixed in equimolar concentrations. By varying agitation time agglomerate size can be controlled within the range 100-500 microns with a specific surface area of 2000-3000 cm<2> /gram.
