Title: Control knob assembly
Inventor: WOOLLARD RAYMOND CHARLES JOHN
IPC: G05G1/10
Filed: 1958-03-20
Abstract: 843,299. Adjusting radio controls. PYE Ltd. March 20, 1959 [March 20, 1958], No. 8969/58. Class 40(5). [Also in Group XXIV] A control knob assembly for electrical apparatus comprises a cylindrical hollow outer knob 1, with an inwardly extending flange 2 adjacent its front end and an outwardly extending flange 3 rearward of the front end, and a second knob 7 rotatably mounted within the first projecting forwardly through it, having an outwardly extending flange 8 which fits behind the inwardly extending flange 2. At the rear of knob 1 are two or more projections 4 which extend through apertures 5 in a disc like rear member 6. The peripheral surfaces of both knobs may be ribbed or knurled, and the knobs made of moulded plastic. The rear face of the knob 7 is formed with a recess 9 to receive a metal key 10 (Fig. 2) which engages with the shaped end of the spindle 12 to be controlled. The rear member 6 is formed with a hole 13 through which passes the spindle 12 and also a surrounding sleeve 14 which serves as a control spindle operated by the knob 1. The end of the sleeve 14 is also shaped to fit into a key 15 similar in shape to the key 10. The two concentric knobs are arranged to project through an aperture 16 in the front panel of a television receiver cabinet 17, the aperture 16 being smaller than the diameter of the flange 3 so that the knobs cannot be removed from the front of the cabinet. The assembly may comprise more than two knobs, for example a further hollow knob similar but larger than knob 1 may be arranged to embrace the flange 3 and be closed at its rear by a member similar to but larger than the member 6. Reference has been directed by the Comptroller to Specification 634,415.

Title: Improvements in or relating to socket-and-spigot pipe joints including resilient seals
Inventor: STRAZNICKY JOSEF
IPC: F16L21/03
Filed: 1970-02-25
Abstract: 1,260,263. Pipe joints; joint-making packing. SEMPERIT A.G. 25 Feb., 1970, No. 8988/70. Headings F2B and F2G. A spigot-and-socket joint, e.g. for joining pipes of large manufacturing tolerances such as stoneware, clay ware, concrete or asbestos cement) incorporates an annular seal of resilient material comprising in its undeformed state an outer ring 4 (Fig. 3) of mean diameter between 5 and 6% larger than the socket, an inner ring 5 of mean diameter between 6 and 8% smaller than the spigot, and a transverse wall 6 joining the rings at or near their ends, the rings being substantially cylindrical when compressed between socket and spigot in the assembled joint. The wall 6 transmits very little radial force and may be inclined, curved, corrugated or buckled to this effect, while the generatrices of the rings 4, 5 when undeformed, may be inclined at an angle to each other or may both be parallel to the seal axis. A distance ring 7 may be attached to either ring 4, 5 and projects into the interannular gap to prevent eccentricity of the spigot when large pipes are joined. One or more clamping lips 7, 9 directed away from wall 6 (Fig. 16) may project from either ring to bear on the opposite ring and these may be undercut on the side away from wall 6. An annular ring- shaped shoulder 8 may also be provided behind wall 6 to assist " rolling " of the seal on insertion of a spigot in a tight joint and thereby prevent the seal breaking away from the socket. Collars 12, 13 may be provided to abut the ends of the spigot and/or socket, and a projection 14 may be provided on the inner ring to engage one of the clamping rings. The sealing member may be adhesively bonded to either the spigot or socket at manufacture, and the joint may be sealed with adhesive on assembly. Suitable materials for the sealing member are polychloroprene, S.B.R., isopropylene, P.V.C., chlorosulphurized polyethylene.

A PN junction is produced by alloying an aluminium-silicon alloy, preferably of eutectic composition, to a silicon body, at a temperature between 650‹ and 670‹ C. and then cooling slowly to 470‹ C. The alloy may be prepared by heating aluminium and silicon to about 950‹ C., cooling to 550‹ C., etching, cutting and pressing into plates while being heated several times during the process to preserve ductility, and melted into balls on a graphite plate. These are placed into conical recesses in a silicon body and may be retained in place by silicone fluid. Alloying is effected at 670‹ C. with slow cooling from 670‹ to 570‹ C. in vacuum or hydrogen. Fig. 2 shows a transistor prepared according to the invention with silicon body 1<1>, base electrode 4<1>, emitter and collector electrodes 2<1> and 3<1>, each with a recrystallized silicon region 5<1> of about 40Á thickness.

Abstract: 416,986. Moving signs. ELWORTHY, F., 24, Pasture Close, North Wembley, Middlesex. March 29, 1933, No. 9380. [Class 3 (i).] A sign mounted on a vehicle and having a display surface comprising a plurality of intermittently rotated drums 13 and a series of succesively illuminated lamps 43 is actuated by a vibration or acceleration operated pendulum 23. The pendulum rod 22 has screwed ends whereby both its period and its effective length in oscillating a pawl 35 can be adjusted. The ratchet wheel 36 operated by the pawl 35 is on a shaft 27 which carries also a toothedwheel engaged by a spring-pressed detent 38 which is released by a striker on the pawlcarrying rocker 32. The motion is conveyed from the shaft 27 to the drums 13 by an endless chain passing over a sprocket on each roller consecutively in opposite directions. An adjustable slotted member 25 surrounds the rod 22 to bias the pendulum and prevent its reaching the vertical position. Cams on the shaft 27 make and break the contacts of the lamps 43. In a modification the shaft 27 is rotated by a pawl oscillated by a weight suspended by a spring.

Abstract: 970,246. Polarizing apparatus. G. VALENSL March 14, 1962 [March 15, 1961; June 8, 1961; Aug. 28, 1961], No. 9800/62. Heading G2J. [Also in Divisions G4, H1 and H4] In an arrangement for controlling the colour and intensity of light passing from a source #to a screen EP utilizing transparent bodies which are rendered birefringent in proportion to the intensity of applied electric fields, six such bodies K 1 , K 2 , K<SP>1</SP> 2 , K 3 , K<SP>1</SP> 3  and K 4  are employed in association with plane polarizing elements P, A 1 , A 2 , A 3  and A<SP>1</SP> of which A 1 , A 2 , As and A<SP>1</SP> are aligned with their polarization axes parallel to each other and crossed with respect to the axis of P. Bodies K 1 , K 2 , K<SP>1</SP> 2 , K 3  and K<SP>1</SP> 3  are controlled by a common signal C the amplitude of which determines the predominating wavelength which is selected. Each of the bodies produces the same retardation between the two light components produced by the birefringent action. Body K 1  functions primarily to select the desired predominating wavelength whilst bodies K 2 , K<SP>1</SP> 2 , K 3  and K<SP>1</SP> 3  function to modify the spectral distribution of the transmitted light so as to increase the colour saturation. Body K 4  is controlled by a separate signal L 1  and functions to determine the intensity of the transmitted light. Polarizing elements A 3  and A<SP>1</SP> are not crossed with respect to each other and signal L 4  is arranged to be inversely related to the desired light intensity. The arrangement shown in Fig. 7 illustrates a light modulating method which is employed in colour television image display systems (see Division H4). In some systems there is provided a line of arrangements as shown in the Figure, one for each elemental area into which a television image line is considered to be resolved. In other systems the birefringent bodies are incorporated in cathoderay tubes and each extend over an area sufficient to permit light modulation point-by-point over the whole television image area. In one of these systems bodies K 3  and K<SP>1</SP> 3  are dispensed with, in another system only bodies K 1  and K 2  are used (intensity modulation as by K 4  being dispensed with entirely) and in another system body K, is located between crossed polarizers and is controlled by a signal directly related to the desired light intensity. Specifications 851,430 and 891,957 are referred to.
