Title: Electron gun and method of manufacture thereof
IPC: H01J29/48
Filed: 1962-10-10
Abstract: 1,016,169. Cathode-ray tubes. RADIO CORPORATION OF AMERICA. Oct. 10, 1962 [Nov. 7, 1961], No. 38437/62. Heading H1D. To reduce the stray capacitance between the cathode 12 and accelerating electrode 16 of an electron gun 10, these electrodes are mounted on separate pairs of insulating support rods 24, 25 with the control electrode 14 secured to both pairs of rods to provide an integral structure. The spacing between the emissive wall 28 of the cathode and the electrode 14 may be adjusted by sliding the cathode 12 within its support ring 32 and/or by sliding the ring 32 within the cathode shield 30, members 30, 32 then being welded together. The correct spacing between members 12, 14 is determined by adjusting to obtain a selected capacitance Cx between members 12, 16, the stray capacitance therebetween being further reduced by the presence of metal capacitance shields 48 which are connected to the electrode 14 and earth. The shields 48 may be removed after the spacing operation is completed or may form a permanent part of the gun 10, which also includes a focus electrode 20, first and second lens electrodes 18, 22, spring snubbers 46 and a ring getter 47. The cathode 12 encloses a coil-type heater 42 supported by straps 44, and the shield 30 and the various electrodes are welded to U-shaped elements whose legs are secured to the supports 24, 25, which are axially aligned.

Title: Improvements in or relating to spot type disc brakes
IPC: F16D65/54
Filed: 1962-10-12
Abstract: 992,282. Disc brakes. H. TEVES, E. A. TEVES, and M. TAUSEND, [trading as ALFRED TEVES MASCHINEN-UND ARMATURENFABRIK KOMM.-GES.]. Oct. 12, 1962 [Oct. 24, 1961], No. 38721/62. Heading F2E. A spot type disc brake is hydraulically and manually operated and has friction pads 3 which are carried and guided in the arms of a U-shaped casing 2 embracing the disc 1 and which are moved to engage the face of the disc, through caliper arms 4, 5 and a double-armed lever 6, by an hydraulic actuating cylinder 13 or by a cable 17, the disposition being such that the brake-operating force is directed through the oasing at an inclination to the plane of the disc. The caliper arms 4, 5 are pivoted to the casing 2 at 11, 12. The free end of the caliper arm 5 is pivoted to the lever 6 at 10, which is also the fulcrum of this lever. A draw rod 7 connects the free end of the caliper arm 4, through a pivot 8, to a pivot 9 on the lever 6, the distance between the pivots 9, 10 being the shorter arm of a double-armed lever. The longer arm is the distance between the pivot 10 and a pivot 14 when the end of the piston from the cylinder 13 is connected to the lever 6. The cylinder 13 is integral with the casing 2 and its axis is inclined to the brake disc 1. In a modification the hydraulic cylinder is integral with the caliper arm which is pivoted to the operating lever. In another modification the base of the cylinder is pivoted on the same pin as that on which the caliper arm pivots. In all these arrangements the brake operating force 18 directed through the casing at an inclination to the plane of the disc. Known wear-compensating means, e.g. 15, 16, may be incorporated.

Patent GB-812092-A (GB)
Title: Process for the production of borides
IPC: C22C29/14
Filed: 1956-12-21
Abstract: A boride or a mixture of borides is synthesized by reacting boron carbide and carbide and oxide of titanium, vanadium, chromium, zirconium, niobium, molybdenum, hafnium, tantalum, or tungsten, or mixtures of such carbides and oxides at a temperature at least as high as the metathesis temperature, 1400 DEG  C. of B4C to boride of the metal or metals and carbon monoxide, and in stoichiometric proportions to substantially completely decompose the B4C and produce boride of the metal or metals. The reactants may be moulded to produce shaped boride articles. The maximum temperature varies from 1900-2250 DEG  C., depending on the boride produced.  The reducing atmosphere of CO formed may be maintained in the furnace, but the gas pressure is usually below 1 atm.  A granular boride is produced by packing the reactants round the graphite resistor of a closed resistor furnace.  For shaped articles, the reactants are placed in a graphite mould having graphite plungers to which mechanical pressure of at least 500 lb./sq. in. may be applied by hydraulic press and an induction heating coil heats the mould in a tube furnace.  Pressures of 2,500 lb./sq. in. may be used.  The B4C may contain an excess or deficiency of B, and where zirconium is used it may contain the normal content of hafnium.

Title: Bobbin winding machines
IPC: B65H67/04
Filed: 1975-09-23
Abstract: 1525015 Conveying wound packages from machines W REINERS VERWALTUNGS GmbH 23 Sept 1975 [1 Oct 1974] 38976/75 Heading D1F A process for the removal of cross-wound bobbins 30, 30a, Fig. 1, from winding stations positioned in succession to one another on both sides of a plane of symmetry 21, comprises means 34 transportable in the plane of symmetry of machine for moving each completed package into the plane of symmetry 21, raising the package up to a conveyor 48 having a run for conveying the packages along said plane above the winding heads, and unloading the packages at the end of the textile machine. In Fig. 1 the packages 30, 30a are carried by cradles 29, the packages resting on driving rollers 28. When a package is fully wound, the cradle supporting it will have been raised to a setting in which they actuate an approximation switch 65. This causes a cutter 24 to sever the yarn, a suction duct 26 to take-up the continuously supplied filamentary material, and a gripper 40 or 41 to be raised upwardly by means of a guide 80 to cause the package to be lifted out of its cradle and deposited on a central receiving trough 83 of a bobbin lift 44. Above the winding stations is a conveyor chain 48, one run of which is directly over the central plane 21. The bobbin lift 44 raises a completed package to such a height that a hook 54, Fig. 5, carried by the conveyor chain 48 enters a central aperture 88 in the wound package to move the package of the trough 83 and carrying it to the end of the row of textile machines. The grippers 40, 41; trough 83 and lift 44 are all part of a bobbin changing mechanism 34 that travels along rails 32, 33, the bobbin changing mechanism 34 carrying empty bobbins 38 and means 42 for moving an empty bobbin into a vacated cradle 29. When a package has been conveyed to the end of the row of winding units it is carried round a return wheel to proceed in the opposite direction. During this stage, Fig. 7, it actuates a proximity switch 90 that causes a bobbin stop 57 to move from a full-line setting to a broken line setting to allow the wound package 30 to pass. On further movement of the package a pin 89 on the hook 54 slides up an inclined surface of a stationary skid 56 to cause the hook 54, carrying the bobbin, to swing clockwise. At the same time the switch 90 causes the bobbin stop 57 to swing back to its full line setting at the rear of the package to prevent the package from moving clockwise with the hook 54. The package is thus doffed from the hook 54 and rolls down a surface 58, Fig. 9. onto a conveyer belt 59.

The duct 5 may be arranged eccentrically in the support 1 and the sectors instead of being of rectangular cross-section shown, may be of circular or elliptical section. The sectors may also have a positive or negative circumferential rake or clearance starting from their cutting edge 4.

A positive yarn feed for a circular knitting machine comprises two pairs of closable nip rollers between which the yarn is directed so that it may be selectively fed at two different rates. Each of two drive rollers 12, 13 cooperate with two pressure rollers 17, 17'; 20, 21' respectively so that the device feeds two yarns. Each pressure roller is carried by an arm, pairs of which 18, 18'; 21, 21' associated with each driven roller are mounted on pivots 6, 11 and spring urged together. Yarn guides associated with the pressure rollers are also carried by the arms. Cams 30, 30' are mounted between the arms and are turned by striking arms 29, 29' to force the arms apart. This position is maintained by arrangement of pins 28, 28' in catches 27, 27'. When one pair of arms, e.g. 21 21' are forced apart the others are allowed to spring together by releasing the catch.
