IPC: H01J61/94
Filed: 1957-01-23
Abstract: 821,668. Fluorescent discharge lamps. GENERAL ELECTRIC CO. Ltd. Jan. 23, 1958 [Jan. 23, 1957], No. 2474/57. Class 39(1). In a colour lighting arrangement a D.C. operated discharge tube has an electrode arrangement at each end capable of acting either as a cathode or as an anode and is filled with at least two rare gases at such relative partial pressures as to be separable by electrophoresis and contains fluorescent material excitable by the passage of an electric discharge through the rare gases, the tube being in combination with circuit components which include a polarity reversing switch, and the fluorescent material and rare gases being chosen so that in one polarity of connection, after separation of the gases has occurred, the resultant light emitted from one end of the tube is different from that emitted from the other end and on reversing the polarity, and after the gases have again separated, the resultant light changes at least at one end of the tube. A suitable filling is neon at a partial pressure of between 2 and 10 mm. Hg and xenon at a partial pressure of less than 1 mm. Hg. The fluorescent material may be a coating on the envelope or on letter forms inside the tube, and its distribution or composition along the tube may be non-uniform for example one end of the tube may be coated with willemite and the other with calcium tungstate. Many examples of suitable fluorescent material, gas fillings and the resultant colours of the light produced are given.

Abstract: 1,082,654. Disc brakes. GIRLING Ltd. Jan. 12, 1965 [Jan. 21, 1964; Aug. 29, 1964], Nos. 2527/64 and 35468/64. Addition to 1,075,371. Heading F2E. The disc brake of the parent Specification is modified by the addition of a mechanical arrangement for applying the pads as an alternative to application by fluid pressure. This may take several forms, one form being a lever pivotally mounted on the yoke 16 and acting on the directly actuated pad 20 via a bifurcated number guided in the yoke, an alternative arrangement comprising cables attached to spaced points on the pad 20 and passed around pulleys on the yoke, and a further alternative comprising a wedge or equivalent expander operating between the inner ends of the pistons 13, 14 in the cylinder formed in the fixed structure 10. A preferred form comprises a lever 36 carried on a crank-pin 37 journalled in the yoke 16, the cranked ends of which engage a U-shaped member 39 which in turn engages a portion 26 of a screw-type adjuster 26, 27 of which the latter portion passes through the outer piston 13 and is held against rotation in the inner piston 14, either by a locking ring 31 or by threaded engagement (Fig. 4, not shown). Automatic adjustment of the adjuster is effected by a pawl carried by the pin 37 and engaging a ratchet-wheel 41 formed integrally with the portion 26, on rocking of lever 36 beyond a predetermined limit. Adjustment can be arranged to take place during either release or application of the brake. The portion 27 is sealed in bore 28 of piston 13 by seals 29 which may have sufficient friction to cause piston 13 to move with the adjuster, to avoid the danger of air being sucked into the working space between the pistons. In normal fluid operation, the pistons are moved apart, piston 14 applying pad 20 directly, and piston 13 acting on the yoke 16, which is slidably guided by engagement with grooves in the outer surface of the portion of structure 10 supporting the pad 20, so as to apply pad 23 whose backing plate 24 is secured in a recess in the yoke. 1,082,655.

[Class 19.] A brushmaking machine comprises a filling nozzle so arranged that a knot of bristles can be fed to it selectively from alternate storages so that different parts of one brush may differ in size or quality of bristles. In the preferred form of apparatus, each kind of bristle is fed through a separate channel k<1>, k<2>, Fig. 1, to a picker f which transfers it to a filling nozzle m. On a power shaft a, Fig. 2, is fixed a cam a<1> operating a lever a<3> pivoted at a<4> and provided with a cam roller a<2>. The lever at its upper end has a universal joint a<5> connected to a rod d<2> which is again connected by a universal joint to an arm d<1>. This arm is fixed on the lower end of a vertical shaft c rocking in bearings in the standard h of the machine and carrying the picker f provided with a groove f<1> for the bristles. The channels k<1>, k<2> hold the bristles upright and pushed forwards by sliding pins k<6>, k<7> operated by weighted cables k<12>. Brush stocks are held in a pivoted member m<3>, Fig. 1, and during the reciprocation of the picker f by the cam a the grooved member f<1> is moved across the ends of the troughs k<1>, k<2> and carries a knot of bristles to the nozzle m through the usual slot. To close one or other of the bristle troughs, shutter mechanism is provided consisting of fingers n<1>, n<2> pressed against the picker f by springs n<3>, n4. The fingers are supported in detachable spring-pivoted blocks n<5>, n<6>. The shutter fingers n<1>, n<2> have pivot pins n<9>, n<10> running in curved grooves n<11>, n<12> in the blocks n<5>, n<6>. These pivot pins also connect the pins n<1>, n<2> to a quadrant member e with a boss e<5> loosely surrounding the shaft c, and on the lower end of the boss e<5>, Fig. 2, is an arm e<1> universally jointed at e<6> to a lever e<2> pivoted at e<3> to the standard h. During the rotation of the shaft a, an eccentric e<21>, Fig. 3, reciprocates a pawl e<15> and rotates a cam e<12>, Fig. 1, intermittently, which reciprocates a lever e<8> and rod e<4> and thereby the lever e<2> which reciprocates the arm e<1> and the quadrant e carrying the shutter fingers n<1>, n<2>. At one end of the movement of the quadrant e, the shutter finger n<1> prevents bristles moving from the trough k<2> so that the picker collects bristles from the trough k<1> only, and so on. To ensure the closure of the picker groove f<1> a shoe k<16> is pressed into engagement with the picker f and for a similar purpose the block n<6> also pressed against the quadrant f. The movement of the shutter carrying quadrant e is limited by adjustable stops s<1>, s<2>. Alternative bristle storages might be arranged on opposite sides of the nozzle with openings therein on both sides.

Abstract: 1,031,032. Grinding. BRITISH AIRCRAFT CORPORATION (OPERATING) Ltd. Jan. 22, 1964 [Jan. 22, 1963], No. 2731/63. Heading B3D. [Also in Division F2] A method of making a bearing having two elements 11, 12, Fig. 1, each of which has at least three coaxial circular raceways 16, 17 of different diameters, and a multiplicity of balls or rollers distributed round and co-operating with the raceways, comprises forming the raceways to a high degree of accuracy and then bringing them to an even higher degree of accuracy by a lapping operation, whereby irregularities of the individual raceways are worn away. Preferably each element has four to six raceways each of part-circular crosssection and initially machined to an accuracy of 0À0002 inch. Lapping of the grooves is then effected by placing pumice and industrial grade balls 18 in the grooves and rotating one element relative to the other at, for example, 60 r.p.m. Alternate balls may be slightly smaller to provide a reference surface for comparing the appearance of the lapping balls during the lapping operation as the balls wear. The lapping may be effected in two stages first using balls accurate to 0À000,05 inch and then using balls accurate to 0À000,02 inch. After dismantling and cleaning, the bearing is assembled using more accurately spherical balls and the errors in circular motion of the bearing may be about 0À000,015 inch or less. Each element may also be lapped against a third element which has been similarly machined. In another embodiment, the raceways lie in different planes and may have part-conical cross-sections. In a further embodiment, the elements 31, 32, Fig. 4, receive tapered rollers 38. In yet another embodiment, the elements 41, 42, Fig. 5, have raceways for balls 48a and rollers 48b.

Title: Improvements in hydraulic variable-speed transmissions
IPC: F16H61/42
Filed: 1957-01-28
Abstract: 857,922. Hydraulic transmissions. WESTON, B. April 28, 1958 [Jan. 28, 1957], No. 2977/57. Class 69 (2). The major axes of the stationary elliptical cams 6, 7 against which the spring biased rollers 8 of the pump and motor of an hydraulic transmission react, are inclined at 45 degrees to each other. A disc valve 11 is rotatable between limits by hydraulic pressure on one side or the other of vane 12. In the neutral position shown in Fig. 2, where the four slots 26 of the valve 11 are arranged so that each pump axis is cut symmetrically by two slots, the pump output is zero, since of the grooves 5 of the pump covered by any one slot 26, an equal number are decreasing in volume as are increasing. As disc valve 11 is rotated, the pump output increases from zero and the ability of the motor to absorb liquid decreases, causing an increasing motor speed. The direction of rotation of the motor depends on the direction of rotation of the disc valve 11 from its neutral position. The invention may be applied to transmissions with other types of pump and motor.
