IPC: H01F1/04
Filed: 1964-02-12
Abstract: 1,057,904. Continuous-casting processes; making magnets. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Feb. 12, 1964 [Feb. 15, 1963], No. 5912/64. Headings B3A and B3F. A Ni-Al-Co-Fe alloy for permanent magnets is continuously cast, the wall of the tubular mould being kept at such a high temperature that substantially the whole quantity of heat is conducted away in an axial direction, and the casting withdrawal rate is not more than 0À1 mm./sec. Alternatively the casting is withdrawn intermittently, the delay periods between movements of the casting increasing as the rate of movement increases. Powdered metal (.1), Fig. 1 (not shown), is fed to a melting crucible (4) which may have an inert gas atmosphere and is withdrawn through the heated die opening (5) which with the iron starter bar (12) and cooling zone (15) causes the axial withdrawal of heat. At (17) the casting is rendered magnetically anisotropic and is then cut into pieces which are magnetized.

Title: Improved process and apparatus for the manufacture of writing materials
IPC: C09D13/00
Filed: 1920-02-28
Abstract: 164,439. Lafeuille, C. J. F. Feb. 28, 1920. Pencils and leads; pencil-holders. - In the manufacture of writing-compositions, a mixture of fusible agglutinant substance and writing- material, preferably a sulphur-graphite mixture, is heated on a liquid or vapour bath, such as oil or steam under pressure, to a determined degree of temperature above the melting-point of the agglutinant, and is then kneaded. Writing-devices are formed from this mixture either by pressing it into previously heated and lubricated moulds to form writing-points of cylindro-conical form for use in the usual pencil-holders, such as split resilient tubes, or by dipping a rod of wood &c. into the melt to form a solidified drop of writing-material on the end of the rod. In the form of apparatus shown, the mixture is heated in the trough 4 on the oil bath 1, the temperature of which is regulated by means such as the thermometer 3. The moulds 5 are also heated on this bath and may comprise pairs of metal strips 9 with cavities 8 forming the complete mould when the strips are brought together. These strips 9 are provided with registering-devices 11, 12 and are mounted in frames 10 hinged together at 7, the frames 10 closing the open ends of the cavities in the first pair of strips, this first pair closing those in the second pair, and so on.

Title: Improvements in or relating to pressure sensing devices
IPC: G01L7/16
Filed: 1955-03-02
Abstract: 774,156. Pressuresensing devices. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. March 2, 1955 [March 10, 1954], No. 6151/55. Class 106 (2). An absolute pressuresensing device comprises a member 21 having a bore 22, a piston 25 movably supported in the bore 22 and dividing the bore into first and second chambers 26, 27, means providing a first restricted orifice Al in communication with the chambers 26, 27, means 30 for connecting the first chamber 26 to a source of fluid under pressure, and means 32 for maintaining critical flow conditions including a second restricted orifice A2 connecting the second chamber to the ambient, whereby when critical flow conditions prevail in the orifice A2, the piston 25 is subjected to a force which varies as the absolute pressure PI of the fluid. When fluid under pressure flows through an orifice, e.g. A2, the volumetric flow increases with pressure until the pressure attains a certain value, the critical pressure, beyond which the flow is constant regardless of increase in pressure. This type of flow is such that the pressure ratio of PI in chamber 26 to P2 in chamber 27 is constant, so that the resultant pressure on the piston 25 when critical flow conditions prevail is proportional to the absolute pressure P1. The rod 28 carrying the piston moves against gravity or a spring 32 to give an indication of the pressure PI to operate valves &c. according to the pressure. The passages 29a, 29b permit equalization of pressure in the bore 29a with that in the chamber 27.

Title: Brake pressure proportioning device
IPC: B60T8/28
Filed: 1962-02-19
Abstract: 939,889. Fluid-pressure brakes. KELSEY-HAYES CO. Feb. 19, 1962 [March 3, 1961], No. 6282/62. Class 103 (1). [Also in Group XXIX] Means for reducing hydraulic pressure to the rear wheel brakes of a motor vehicle comprises a valve interposed in the conduit 15 leading from a master cylinder 10 to rear brake cylinders 19, a direct connection 12 leading from the master cylinder to the front brake cylinders 14. The valve is of the inertiaoperated type responsive to deceleration of the vehicle and comprises a steel ball 34 acting as inertia mass and also as a valve to close the entrance 26 to a passage 25 formed in a block 24 of resilient material. The ball is normally held away from the entrance 26 by magnetic force exerted by a magnet 50 mounted in a piston 41 which is held against a shoulder 44 by a spring 49. When pressure is built up in the system fluid passes directly to the front brakes and is initially free to pass to the rear brakes via passage 25 and conduit 17. When the resulting deceleration is sufficient to overcome the magnetic force the ball 34 seats in the entrance 26. Thereafter, increasing pressure in the conduit 15 causes the block 24 to distort progressively, the pressure in conduit 17 being less than the pressure in conduit 15 by an amount corresponding to the resistance of the block to distortion at any given time, until a space 28 is filled with the material of the block, after which no further increase in rear brake pressure can occur. Should brake fade occur or for any other reason a higher braking pressure than -normal occurs before a deceleration sufficient to overcome the force of magnet 50 is produced, piston 41 moves under the higher pressure so that the magnetic force is weakened, thus permitting the ball to move at a lower deceleration to close the entrance 26.

Filed: 1926-03-09
Abstract: 258,790. Fitzpatrick, H. D., (Marquette Tool & Manufacturing Co. March 9, 1926. Cupping.-A press for drawing sheet metal is provided with means for applying a constant pressure to the draw-ring during the drawing operation, and for preventing backlash on the release of this pressure at the end of the stroke. The draw-ring 15 is supported by pins 16 resting on a pressure-pad 17 carried by a spring 27 mounted on a ring 26 which is adjustably supported on a plate 23 by a nut 25. The plate 23 is supported by a spring 2 carried by a plate 21 which is supported by fixed hangers 43. A fixed piston 30 works within a cylinder 29 carried by a rod 18 passing loosely through the plate 21. The upper end of the cylinder 29 is constantly open to the atmosphere by way of a port 18<a>, the lower end of the cylinder communicating with a valvebox 34 by connections 35, 38, Fig. 3, fiuid-pressure being admitted to the valve-box through a pipe 32, Fig. 1. On the drawing stroke of the press the spring 27 is first compressed to a given extent after which drawing proceeds with a constant pressure on the blank-holder, due to the thrust pins 28. A charge of fluid under pressure is thereby admitted to the cylinder 29, this charge being slowly expelled on the return of the upper die, thus preventing a violent return of the blankholder. A number of such cushioning devices may be fitted.
