Title: Improvements in or relating to television receivers
IPC: H01J29/14
Filed: 1938-02-03
Abstract: 513,776. Television receivers. SCOPHONY, Ltd., and ROSENTHAL, A. H. Feb. 3, 1938, No. 3434. [Classes 39 (i) and 40 (iii)] A screen of a crystalline alkali halide or like material is scanned to produce an opacity which is brought to a datum at frame frequency. A crystal 9, Fig. 1, e.g. of potassium bromide, is scanned by a modulated cathode ray beam, the electrons injected into the crystal forming an opaque deposit which moves through the crystal . at a velocity dependent upon the potentials of the electrodes 10, 11, and the temperature of the crystal. These factors are adjusted so that the opaque deposit completes its traverse in a frame period. Electrodes 10, 11 may be dispensed with, the surface charge being utilized to produce the desired field. The electrode 10 may be replaced by a secondary emitting layer, either to increase the opaque deposit or to produce a surface charge. The crystal is maintained at a constant temperature by thermostatically controlled heating coils within, or without, the crystal, Figs. 4, 5, not shown. The crystal may be mounted outside the cathode ray tube on an electrode forming the end wall, Fig. 2, not shown. The opaque deposit may be brought to a datum level by a second cathode ray beam immediately preceding the modulated cathode ray beam, Fig. 6, not shown. In a modification, the crystal is scanned by light of one wavelength, and imaged on the screen by light of another wavelength, Fig. 3, not shown. The scanning may reduce or increase the opacity of the crystal.

[Also in Group IX] Yarn length metering mechanism has a metering wheel which is turned by the yarn passing thereover, a gear-wheel system coupled to the wheel and contacts on each of the gearwheels which contacts complete an electrical circuit for terminating the sealing or winding operation only when the wheels return to their original relative position. Instead of the contacts each gear-wheel may have a hole therethrough which holes co-operate to complete an optical path only when the wheels return to their original relative positions. As shown, yarn 2 passes over metering wheel 1 and thus rotates the train of gear-wheels 4, 5, 6, 7 and 8. Wheels 4 and 8 each have a single contact 12 and 13 which are connected to their respective shafts 3 and 14 whilst the remaining wheels each have two contacts connected respectively by conductors 9, 10 and 11. The arrangement is such that an electric circuit is completed in one relative position only of all the wheels and that position is only reached after the required length of yarn has passed over the wheel 1. In an alternative arrangement two sets of gearwheels are used in parallel.

Filed: 1927-02-09
Abstract: 290,344. La Bourdonnais, Prince de Mahe, C. M. de C. de. Feb. 9, 1927. Diaphragms; loud-speakers. - A large conical diaphragm d is attached at its centre directly to the movement as shown in Fig. 1, and is supported peripherally from a rigid ring c by three equidistant lugs f, Fig. 3, formed by cutting away the intervening portions of the material forming the diaphragm. In this way it is stated that a substantial portion of the diaphragm vibrates by " piston " action whilst the remainder vibrates by flexure from the periphery. The conical diaphragm is mounted as a whole inside a shallow horn b of circular or polygonal form so as to leave an annular space, e. Sound waves are accordingly propagated from both sides of the diaphragm. The pitch of the sounds is controlled by moving the cone d relatively to the horn b, the arrangement being such that sound waves from the core do not impinge at right angles to the reflecting surfaces of the horn. The diaphragm may be built up from a plurality of conical laminae so that its thickness increases from periphery to centre; or it may be so impregnated as to acquire a graded elasticity from periphery to centre. In such cases the diaphragm may be supported around the entire periphery so as to vibrate partly by piston action and partly by flexure. The diaphragm may be made of onozote, a rubber composition described in Specification 162,176, [Class 70, Indiarubber &c.], the thickness of the diaphragm increasing from periphery to centre.

Abstract: 897,522. Electrically-released switches; electromagrietic relays.. TELEPHONE MANUFACTURING CO. Ltd. Feb. 4, 1959 [Feb. 6, 1958], No. 3892/58. Class 38 (5). A relay has a single core and two armatures, one of which is retained by remanent magnetism. Each armature 1a, 1b operates a contact stack 4, 5 by means of an actuator 10a, 10b and is pivoted on the end of the yoke 3 and retained by a bridge 7 and screw 8. The armature 1b is provided with a screw 9 to set the minimum gap between it and the core end 2 ensuring that it is released on de-energization, whilst the armature 1a has no such gap so that it may be retained in engagement with the core. The core, core end or armature 1a may be the member having the remanent magnetic properties. A reverse flux in the relay causes the release of the armature 1a before both armatures are re-attracted. The relay may have a single winding which has to be energized in the reverse direction to release armature 1 or it may have two windings with a resistance to limit the current in the release winding to a value insufficient to cause the re-attraction of the armatures. In either case the contacts of the stack 4 may be connected in the energizing circuit to set the relay for release. Specification 897,523 is referred to.

Abstract: 1,070,172. Rolling tubes. BLAW-KNOX CO. Jan. 31, 1966 [Feb. 15, 1965], No. 4126/66. Heading B3M. A tubular blank W is rolled between pairs of grooved rolls 6<SP>1</SP>-10<SP>1</SP> while supported by a mandrel 14, the mandrel being moved, during the rolling process, relative to both the blank and the rolls. The mandrel, which is attached to a thrust rod 15, is moved to the right by means of a chain-driven thrust block 16 until it lies between the rolls 9<SP>1</SP>, Fig. 12 (not shown). The blank is advanced by a pusher 19 to a position between the rolls 6<SP>1</SP>, a heat sensor 147 signalling the presence of the blank, to initiate operation of a control beam 18. The thrust block 16 is at this stage in contact with the control beam and the grip of the rolls 6<SP>1</SP> on the blank is tending to move the mandrel and thrust block to the right. The speed of advance of the beam 18, controlled by motor-driven screws, thus determines the speed of advance of the mandrel. Conveniently the mandrel is advanced from its position between the rolls 9<SP>1</SP> to a position between the rolls 19<SP>1</SP> during the complete rolling operation, but the mandrel can be retracted during the latter part of the operation. In both cases wear on the mandrel is spread over the working length of the mandrel. Adjacent roll pairs are set at 90 degrees to each other the pairs 6<SP>1</SP>-9<SP>1</SP> reducing the tube, while the pair 10<SP>1</SP> merely ensures that the finished blank is uniformly round in section. The mandrel 14 and also the rod 15 are hollow and accommodate a central tube (102), Fig. 7 (not shown), which is fed with water under pressure for cooling the interior of the mandrel. A further tube (103) carries lubricant for the inside of the blank (W) as the mandrel is advanced, bores (107) serving to direct the lubricant on to the blank. A trough 120 drains off any excess lubricant. A conduit (115) supplies a lubricant for the exterior of the mandrel. A blank W, before being moved on to a trough 12 aligned with the rolls, is positioned on an inlet table, parallel to the trough and provided with motor-driven rollers and hydraulically-operated kick-out arms. Retractable rollers 57 support the mandrel bar 15 when it is not positioned within a blank.
