IPC: B26B21/50
Filed: 1925-11-24
Abstract: 266,445. Kennedy, E. N. Nov. 24, 1925. Razors of the kind using a single-edged blade which can be stropped without removal from the holder, as, for example, in Specification 15230/07, 105,522, and 184,808 are provided with two such blades with independent supports so arranged that they can be held in juxtaposition back-to-back, Fig. 1, for shaving purposes, or separated, Fig. 4, to allow the blades to be stropped simultaneously in tandem. As described, the upper end of the handle 11 is halved, the part 13 being pivoted at 14 to the part 12. Each part 12, 13 carries a crossbar 15 integral with a toothed guard 16 of usual form, and upstanding lugs between which are pivoted spindles 20, 21 geared together by toothed wheels 23, 24 and respectively carrying the blade-holder 19 and a strop-engaging roller below which the strop 22 is passed as shown. The wheels 23, 24 reverse the blade when stropping in the usual way. The parts 12, 13 are secured in the separated or closed positions shown by a sliding member 28 on one part adapted to engage suitable grooves or projections on the other. Alternatively a leaf-spring catch or other means may be used. When in position for shaving, Fig. 1, the blade-holders are held against rotation with the blades 27 against the guards by a projection 26 on one member 15 engaging a toothed wheel, or an arm 25 carried thereby, on the other part. The blade holder 19 has a concave surface against which the blade 27 is clamped by a bar 33 pivoted to the holder at 34 so that it may be swung over the blade and its free end engaged under a catch 35. The blade has positioning notches 36, and apertures 37 to facilitate flexing the blade when clamping in place. Alternatively, the blades may be locked in position for shaving as described in Specification 184,808, the pivotal movement of the guards being effected by trip lugs on the two parts of the handle.

Title: Improvements in or relating to labyrinth parking systems for use in turbines or pumps
IPC: F04D29/16
Filed: 1954-10-15
Abstract: 761,421. Hydraulic turbines; centrifugal pumps. ESCHER WYSS AKT.-GES. Oct. 15, 1954 [Oct. 7, 1953], No. 29782/54. Classes 110 (1) and 110 (3). A labyrinth seal arranged in the flow path of leakage fluid between adjacent parts of a turbine or pump runner and its housing, comprises at least two annular throttling passages leading to and from an enlarged annular space bounded by the runner and housing, so that displacement of the runner radially from the axis alters the width of the passages to produce hydraulic forces to urge the runner back to its correct position. The runner 2 and housing 1 of a Frances turbine are shaped to provide passages 10, 11, 19, 20 leading to and from spaces 13, 22. During displacement in a radial direction axial forces produced in the spaces are balanced but radial forces produced in spaces 22 restore the runner to the central position.

Title: Improvements in the preparation of cupric oxide surfaces
IPC: B05D3/10
Filed: 1961-08-17
Abstract: An organic composition such as a thermosetting or thermoplastic resin, a paint, an adhesive or a lacquer is applied to a copper containing surface which has been treated to form a cupric oxide layer by immersion in a strongly alkaline aqueous solution of an oxidizing agent such as an alkali metal chlorite containing cyanide ions.  Alternatively the cupric oxide layer formed may be reduced to copper cupric to applying the organic coating.  The resins such as polyethylene P.V.C., "Penton" (Registered Trade Mark) or "Teflon" (Registered Trade Mark) are applied either by preheating the work-piece to 200 DEG C. or 300 DEG C. and immersing it in a static aerate of the material or in a fluidized bed or air or flame-spraying it.  Specification 912,464 is referred to.ALSO:A black layer of cupric oxide needles is formed on a copper containing surface by treatment with an aqueous strongly alkaline solution of an oxidizing agent such as an alkali metal chlorite containing cyanide ions.  The solution contains between 0.007 and 0.6 gm. ions per litre of cyanide, e.g. KCN or NaCN, between 0.3 and 1.0 gm. ions per litre of chlorite and treatment is effected between 80 DEG  C. and the boiling point of the solution.  The reaction rate may be increased by making the copper surface an anode and applying a voltage of 3-24 volts to the solution.  The pH of the solution should preferably be at least 12 and the surfaces treated may be copper, brass or bronze.  The cupric oxide layer is used as a base for a coating of a thermoplastic or thermosetting resin, a paint, an adhesive or a lacquer or alternatively the cupric oxide may first be reduced to copper by heating in a reducing atmosphere.  Specification 912,464 is referred to.

IPC: F16D57/04
Filed: 1970-06-19
Abstract: 1,267,340. Arresting aircraft. GULF & WESTERN INDUSTRIAL PRODUCTS CO. 19 June, 1970 [19 June, 1969], No. 29871/70. Heading B7G. [Also in Division F2] A rotary hydraulic energy absorber, particularly for arresting landing aircraft A, has a casing J to which are fixed non-rotary stators 30 forming stator pockets which interact with rotor vanes 32 rotatably attached to shafts 34 fixed to a shaft 26 coupled to reels E, around which are located cables H for engaging the aircraft, the vanes 32 being automatically adjustable to provide a constantly retarding torque with decreasing reel speed. To provide adjustment of vanes 32 a ring member M is positioned to slidably receive in guide channels 38 followers 35 secured to the vanes, rods 44 attached to pistons 42, Fig. 4 (not shown), of hydraulically connected cylinders N being fastened to the member M. Pistons 42 are spring- biased and are held in their uppermost positions in which vanes 32 are parallel to the plane of ring M to provide minimum retardation by hydraulic pressure passed through a line 60 from a master cylinder S coupled through a rod 56, a cam R, reduction gearing P and bevel gear 52, 54 to shaft 26. Cam R rotates once during each arrestment cycle so that at its commencement rod 56 causes master cylinder S to supply fluid to cylinders N to maintain minimum retarding torque, but as the cam rotates the fluid pressure in cylinder N decreases and the vanes 32 rotate to increase the torque. A plurality of interconnected master cylinders S may be provided bolted to baffles T, Fig. 3 (not shown), which are moved into any desired position in the pocket by operation of a valve (76) in the line connecting the master cylinders to adjust the depth of the pockets so that the absorber may be preset for a predetermined aircraft weight. The reel E may be reset by a motor K and a one-way clutch (82) provided so that no torque is transmitted to shaft 26 during resetting. In another embodiment the rotor vanes 32 automatically assume the maximum retardation position on loss of hydraulic pressure to the adjustment device by providing a second cylinder hydraulically coupled to cylinder N.

Abstract: 1,073,159. Rotary engines, motors and pumps. R. JAMES. July 29, 1965 [July 29, 1964], No. 30096/64. Heading F1F. A semi-rotary-piston two-stroke I.C. engine comprises a pair of mutually-opposed pistons (36, 37), Figs. 1, 3, 5, 6 and 7 (not shown), which are lodged in an arcuate cylinder 29 and pivotally supported by a stationary shaft (23), the ends (45, 46) of the pistons being coupled by connecting- rods (78, 83) to crank-pins (72, 73) on a rotatable crank-shaft (62). The cylinder is defined by the inner surface (20) of a wall (16), an arcuate wall (26), and parallel end-walls (17, 18), Fig. 2 (not shown), the longitudinal axis of the cylinder being part-circular and having its centre of curvature lying on the axis of the shaft (23). The crankpins (72, 73) are situated between three coaxial discs (68, 69, 70), Fig. 4 (not shown), the outermost discs (68, 70) being carried by a stub-shaft (74) and a power-output shaft (75), respectively. Fuel-air mixture is drawn into a chamber (97), which contains the crank-shaft, through a pipe (95) whilst the pistons move towards one another; and, during the subsequent power-stroke of the pistons, said mixture is compressed in said chamber before it is transferred to a working space (49) through a recess or groove (100) and a transverse passage (102) in the piston (37), and a transfer passage (106) in the wall (16). The mixture in the space (49) is ignited by a sparkplug (110), the products of combustion being ejected through a port (91) which is controlled by the piston (36). In a modification, Figs. 8 to 10 (not shown), the pistons (36a, 37a) are axially displaced relative to one another so that the connecting rods (78, 83) reside in a common transverse plane. In a further modification, Figs. 11 to 14 (not shown), the crank-shaft (138) comprises a single crank-pin (139) to which the piston (36b) is directly coupled by a connecting- rod (132), the other piston being attached by a connecting-rod (146) to a pin (150) on an arm (142) forming an integral part of the rod (132). Alternatively, the engine operates on a fourstroke cycle, and may be adapted to function as either a fluid-actuated motor or a pump.

Abstract: 1520638 Position determination DYNELL ELECTRONICS CORP 18 July 1975 [22 July 1974] 30226/75 Heading H4D Apparatus for generating signals for use in determining the positional co-ordinates of a given location, e.g. 44 having unknown positional coordinates comprises: (a) reticle means 10 for defining a plurality of separately discernible cells 16 &c., (b) means, e.g. 30, for defining a discernible indicium, (c) means 38 for spacedly positioning the reticle means and the indicium defining means in a field of view, and (d) means for generating a signal indicative of the one of said cells, e.g. 22d, which is on the optical path extending from the given location to the indicium. The apparatus may be used for determining the position of the lens node of a camera at 44, e.g. in the course of photographically assisted reproduction of 3-D objects. A photograph taken by the camera will be as shown in Fig. 2; this is then scanned to derive the signals of (d). The reticle means may be composed of filaments 14, 15; they may be thick wires which are opaque to incident energy, or substantially transparent fine wire filaments. In this latter case, a series of separate photographs of rows 14, columns 15, and the indicia may be taken (Figs. 4-6, not shown), from which the signals of Figs. 7a-7e may be derived. In alternative embodiments, the reticle may be defined by moving lights instead of filaments (Fig. 10, not shown), or a single axis reticle may be used. A reticle such as that shown in Fig. 9 may be used to give a cyclic cell-defining code. Here, cells II, III and V contain an extra line 14a; when scanned, this gives rise to the signal of Fig. 1(f). In general there are P cells, with each succession of N cells giving a term of the code, where 2<SP>N</SP> - 1 = P. This latter embodiment is claimed in divisional Specification 1,520,639.

Title: Improvements in methods of manufacturing permanent magnets
IPC: C22C19/07
Filed: 1957-09-30
Abstract: Magnetically anisotropic permanent magnets are formed by obtaining an alloy consisting of Fe, 28-42% Co, 10-20% Ni, up to 8% Cu and 6-10% Al, the last element with a purity of at least 99.8%, adding thereto 4-10% Ti of purity at least as high as that obtained by the known iodide process, solidifying the alloy by withdrawing heat in one direction only and carrying out thermal treatment in a magnetic field the direction of which coincides with the direction in which heat was withdrawn, care being taken during all these operations to avoid contamination of the alloy so that, after final magnetization the magnet has, at a coercivity of over 1000 Oersted, a (BH) max. of at least 8 times 106.  The Fe-Co-Ni-Al-Cu alloy may be produced by melting previously purified constituents in a protective atmosphere or by adding Al of the required purity to a melt of the other constituents which has been purified in a hydrogen atmosphere. Solidification of the alloy may be performed by lowering the mould containing the alloy slowly out of a furnace while cooling the bottom of the mould, by drawing a rod vertically upwards from the melt using the known method of manufacturing mono-crystals or pseudo-monocrystals, or by the method described in Specification 860,127.  Specifications 821,624 and 852,249 also are referred to.
