Abstract: 885,130. Work-holders. ENGRENAGES MINERVA S.A. Nov. 20, 1959 [Nov. 21, 1958], No. 39470/59. Class 83 (3). A work-holder comprises a base 3, having an interchangeable support 4 secured thereto and a column 1 carrying an hydraulic cylinder 7, the piston 8 of which is secured to a slide 13. A housing 15 secured to the slide carries a rotatable spindle 17 driven from a motor 37 through gears 35, 22. Secured to the spindle 17 is a spindle 25 which rotatably carries a clamp 32, and has a screwed end 40 which engages a spring-urged nut 43 splened in a bore 46 of the support 4. In operation, fluid is supplied to the cylinder 7 at 10, and the piston 8 along with the slide 13 and the spindle 25 move upwardly. A gear blank &c. 38 is fed on to the support 4 from a conveyer 39 and the fluid is exhausted from the cylinder 7, thus allowing the spindle 25 to move towards the blank, either by gravity or by supplying fluid to the opposite end of the cylinder. The motor 37 is actuated, thus rotating the spindle 25 which enters the bore of the blank, and locates the latter. As the end 40 of the spindle engages the nut 43 the spring 47 is compressed until the piston 8 reaches the end of its stroke. At this point, the downward movement is cushioned by a dash-pot- 51 in the cylinder and due to the rotation of the spindle 25 and its threaded engagement with the nut, the latter moves upwardly and pulls the clamp 32 on to the blank. Clamps 32 and supports 4 of different sizes are provided to accommodate various blanks and adjustable torque limit means are provided for the motor 37. The spindle 25 may be retracted downwardly, and in a modification the spindle 25 is non-rotatable and the nut 43 rotates.

Abstract: 1,030,048. Semi-conductor devices. SIEMENS & HALSKE A.G. Sept. 29, 1964 [Sept. 30, 1963], No. 39541/64. Heading H1K. A semi-conductor unit is produced by diffusing gaseous dopant of one type into opposite surfaces of a semi-conductor body of the opposite conductivity type, one surface being masked to limit the diffusion to an annular zone, the process being such that the diffusion joints meet to isolate a region of the original conductivity type inside the annulus. In one embodiment an N-type silicon wafer which has one face lapped and one polished to provide different rates of diffusion is covered with silicon oxide which is then removed from the lapped face and from an annular region, 3, on the polished face. Diffusion is effected with boron trioxide vapour to form P-type regions 7 and 9; the diffusion is effected in two steps, firstly in the presence of the dopant vapour and then in oxygen which results in further diffusion and the provision of a new oxide layer 3 over the diffused region. Diffusion is continued until the two P-regions meet leaving an N-type island 8. A semi-conductor diode may be provided by alloying a metal layer 4 to the N-type region 8 to form an ohmic contact for terminal member 13. Similarly metal layer 11 provides ohmic contact to P-region 7 for base-plate 12. A further embodiment consists of a transistor in which terminal 13 is associated with a further P-type zone extending into N-type base region 8 which is provided with an annular ohmic base contact. Phosphorus pentoxide or trioxide may be used to form N-type regions and germanium or A 3 B 5  compounds may be used in place of silicon. Indium, gallium, zinc, antimony and arsenic may also be used for diffusion.

Title: Improvements in or relating to the purification of beryllium compounds
IPC: C22B35/00
Filed: 1958-12-11
Abstract: Aqueous solutions of beryllium salts for example, the sulphate, are purified by contacting them with zinc hydroxide in the presence of a soluble fluoride, the pH of the solution being maintained at a value lower than that at which beryllium hydroxide would be precipitated, and then separating the solution from the zinc hydroxide.  There is preferably present in the solution at least two atoms of fluorine for each atom of beryllium.  The zinc hydroxide may be formed in situ for example by having present in the solution a soluble zinc salt and adding a base to the solution to adjust the pH to between 7 and 10, thereby precipitating the zinc hydroxide.  The precipitated zinc hydroxide may be recovered and employed to treat further batches of beryllium solution.  Any zinc remaining in the solution may be removed by treating with a soluble sulphide, for example ammonium, sodium, or hydrogen sulphide.  Beryllium may be recovered from the purified solution by precipitation as the hydroxide, for example by the addition of sodium hydroxide or ammonia.  A sodium hypochlorite solution may be added to the solution to be purified to oxidize any iron or manganese present and thereby to facilitate their precipitation. The solution may be prepared by calcining beryl and sodium fluosilicate and leaching.

Abstract: 1,124,650. Anti-skid braking system; drum brakes. FORD MOTOR CO. Ltd. 8 Sept., 1966, No. 40215/66. Headings F2E and F2F. A motor vehicle anti-skid braking system includes a sensor device acted upon by a force which varies with the limiting friction between a friction member and a part rigid with the vehicle wheel and a force dependent upon the actual frictional force between those parts, the arrangement being such that when the limiting friction dependent force overcomes the force dependent on the actual friction force the sensor reduces the pressure in the brake application line. The sensor 9 is disposed between a master cylinder 1 and the drum brake actuator 17 and is further supplied with fluid under pressure from the leading shoe abutment piston and cylinder device 25. While the wheel is rotating the pressure generated in cylinder 25 increases with increase of pressure supplied to the actuator 17. When the wheel locks the frictional force between shoe and drum remains constant but the rising force as an increased pressure is applied to actuator 17 causes sensor plunger 35 to move leftwards, cutting off communication between the master cylinder and the line 52 leading to the brake actuator, the increase in volume to the right of the plunger causing a fall in the pressure in line 52. To prevent the device operating when the vehicle is moving in reverse a rod 45 co-operates with a passage 43 in the plunger to block that passage when the vehicle is moving in a forward direction but to open the passage when the vehicle reverses and no pressure is experienced in line 57 and allow the master cylinder pressure to pass to line 52 despite the leftward movement of plunger 35. In another embodiment (Fig. 6, not shown), both wheels of an axle are provided with cylinders 25; these are connected to the sensor 9 through a valve which operates to connect the cylinder delivering the lesser pressure to the sensor.
