Title: Improvements in or relating to yarn winding mechanisms
IPC: B65H54/36
Filed: 1944-05-05
Abstract: 590,061. Winding yarn. EVANS, W. E. (Foster Machine Co.). May 5, 1944, Nos. 8600/44 and 13799/45. [Classes 120 (ii) and 120 (iii)] In a yarn winding mechanism provided with a rotatable spindle to receive a package core and a yarn guide to be traversed along the core to control the lay of yarn thereon, an idler roller extending the length of the traverse and between which and said package the yarn is laid by the guide, the roller moving away from the core as the package builds up with its axis parallel to the surface of the package, means are provided for shifting the traverse of the guide towards the nose of the package by progressive increments of movement which bear a direct relation to the increased size of the package as it progressively builds up. The thread guide 5 is traversed by the cam 4 through a follower 11 and tube 9, the cam 4 being constructed to give to the guide 5 an acceleration as it approaches the nose of the package and a decelaration as it approaches the base of the package. A roller extending along the length of the package and parallel to the contacting surface thereof, is rocked, with its carrying frame 6, by the growing package, to rotate a bushing 37 about the shaft 3. Attached to the bushing are diametrically opposed studs 43 carrying rollers 44 which engage in cam slots 36 in two plates 35 attached, through ball bearings, with a bushing 27' slidably keyed to the shaft 3. As the package grows, the traverse cam 4 is therefore moved with a motion, determined by the slope of the cam slots 36, towards the nose of the package. The preferred form of cam slots 36 will give an acceleration of movement of the cam 4 towards the nose so to produce a coned package with a convex base and a bevelled concave nose (Fig. 4).

Title: Film recording of television pictures
Inventor: YOUNG ROBERT ERIC
IPC: H04N5/84
Filed: 1952-04-05
Abstract: 742,054. Television. ARMSTRONG WHITWORTH AIRCRAFT, Ltd., Sir W. G. April 7, 1953 [April 5, 1952], No. 8780/52. Drawings to Specification. Class 40 (3). In an arrangement for recording television pictures of objects in a vehicle (e.g. aircraft instruments) on a light-sensitive film at a remote position and employing conventional television transmission apparatus in the vehicle and conventional picture reproducing and film driving apparatus at the remote position the " line " scanning in the latter apparatus is controlled by means of normal synchronizing signals transmitted from the vehicle whilst the " frame " scanning of the transmitting apparatus is controlled by means of a synchronizing signal (related to the frequency of an alternating current source which supplies a synchronous motor in the film driving apparatus) transmitted from the remote position to the vehicle. One embodiment is concerned with a non-interlaced system and in the arrangement described (Fig. 1, not shown), the beam of the picture reproducing tube, which is modulated by the received picture signals, is deflected only in the horizontal direction and the " frame " scan, in effect, provided by the motion of the film. In a second embodiment (Fig. 2, not shown), concerned with interlaced transmission, susuccessive (interlaced) fields are reproduced on the picture tube by means of a sequential " frame " scan so that two separate image fields, each of half the height of a complete interlaced " frame," are produced. These images are then projected on to the film which moves, in the opposite direction to that of the " frame " scanning, at a speed such that the two image fields are recorded as a single interlaced picture on each film frame. Synchronization of the " frame " scanning of the apparatus in the remote position with that of the apparatus in the vehicle is accomplished by transmitting the fundamental, harmonic or subharmonic of the supply to the film-driving synchronous motor from the remote position to the vehicle the " frame " scan of the apparatus which is controlled thereby.

Abstract: 785,419. Centrifugal compressors. SULZER FRERES SOC. ANON. March 21, 1956 [March 22, 1955], No. 8895/56. Class 110 (1). A method of manufacturing a number of single-stage or multi-stage radial-flow compressors having different characteristics comprises making a number of identical housings and at least two different kinds of insertion and rotor sets which can be fitted into the housings without any modification of the latter, one kind comprising a shrouded rotor and an insertion having a wall which lies adjacent to the rotor shroud, and another kind comprising an opensided rotor and an insertion which forms the boundary wall of the blade channels at the open side of the rotor. The compressors shown in Figs. 1 and 2 have identical casings 1, diffuser 11 and shaft 5, but have a shrouded impeller 8 or an open-sided impeller 8<SP>1</SP>, with correspondingly different stationary removable insertions 10 or 10<SP>1</SP> respectively. Insertion 10 co-operates with impeller 8 to form a labyrinth seal 14, while insertion 101 is shaped to provide a wall for the blade channels of impeller 81. Each insertion 10 or 10<SP>1</SP> is split, like the casing 1, on a horizontal plane to facilitate assembly and supports the removable diffuser 11 on one side. The lefthand wall of the diffuser may be integral with the insertion. The impellers, insertions and diffuser may be made in a number of different widths, and the diffusers may be made with different inlet angles. The impeller is clamped against a collar 6 on the shaft by means of a clamping ring 7 or 71, a spacer 12 being interposed in the former case. The invention may be applied to the first stage and, it may be, subsequent stages, of a multi-stage compressor, and is applicable to the multi-stage compressor described in Specification 754,322.

Title: Erbium laser device
Inventor: SNITZER ELIAS
IPC: H01S3/06
Filed: 1969-02-19
Abstract: 1,201,594. Lasers. AMERICAN OPTICAL CORP. 19 Feb., 1969 [29 April, 1968], No. 9045/69. Heading H1C. A first laser 12, Fig. 1, which comprises a trivalent neodymium-doped laser rod 16 pumped by a flash lamp 20, is used to pump a second laser 10 the laser rod 14 of which is doped with trivalent ytterbium sensitizer ions and trivalent erbium laser ions. The first laser provides an output of 0À92 or 1À06 microns and the second laser a 1À5 micron output. As shown the resonators of the first and second lasers are formed by mirrors R1, R2 and R2, R3, respectively, the common mirror R2 and mirror R3 being dichroic so that the first laser passes its output 22 (0À92 or 1À06 microns) into the second laser resonator, while the second laser output (1-5 microns) is obtained through mirror R3. In an alternative arrangement, Fig. 2, normal mirrors R1, R2 form the first laser resonator, and a mirror R3 and a total internal reflecting facetted end 26 of the laser rod 18 form the second resonator. The first laser output 22 is introduced into the laser rod 18 through a facet S1 and follows a zig-zag internally reflecting path 30 until it emerges through a facet S2. A mirror R1 reflects the emergent pump energy back into the rod. In a modification, Fig. 3, the second resonator is formed by mirrors R3, R4 and an inclined end surface S3 of the laser rod 18, the pump energy being introduced through this surface and again following a zigzag path 30. Higher pumping efficiency is stated to be obtained by heating the second laser rod.

Title: Improvements in or relating to hobbing machines for generating the teeth of gear wheels with helical teeth
IPC: B23F5/22
Filed: 1922-03-30
Abstract: 200,157. Shaw, F. W. March 30, 1922. Gear-cutting.-In a hobbing - machine for generating helical gears an endwise movement is imparted to the hob during its traverse across the work, the gearing between the hob and work being the same as for cutting straight spur gears. Alternatively where this method would necessitate the use of very long hobs, the " creep " of the hob may be effected partly by modification of the change wheel ratios and partly by imparting endwise movement to the hob. The vertically arranged hob saddla 2 is provided with a slide 4 on which the hob saddle is pivotally mounted and the endwise movement of the hob during its vertical traverse is affected by means of a slipper 7 sliding in an adjustably inclined guide 8. In a modification the slide 4 is mounted on an angularly adjustable plate pivoted to the hob saddle. In a further modification the slide 4 may be traversed by means of a screw driven at the required speed. Specification 19932/14 is referred to.

Title: Improvements in the manufacture of artificial textile materials
IPC: D01G1/08
Filed: 1933-03-28
Abstract: 417,326. Staple fibre yarns; spinning-machines. DREYFUS, H., 22, Hanover Square, London. March 28, 1933, No. 9310. [Classes 120 (ii) and 120 (iii).] Apparatus for the production of staple fibre yarns from continuous filaments comprises pairs of breaking rollers, one roller of each pair having an unyielding surface covered with protuberances which localize the pressure applied to the filaments between the rollers. The other roller of each pair may be surfaced with slightly yielding material. The protuberances may be formed in a knurled or lozenge pattern by grooving the roller helically in both right and left-hand directions. Any sharp edges in the projections formed may be rounded off by sand-blasting. The yielding surface of the other roller may be of leather, cork, or rubber so that the protuberances of the unyielding roller sink therein and spread to some extent the localized nipping force. All the continuous filaments between the rollers are thus always under tension but different filaments are periodically subjected at different times to a tighter nip and broken. The device may be used for natural or artificial continuous filaments such as those regenerated from viscose or cuprammonium solutions and those of cellulose acetate or other cellulose ester or ether. As shown in Figs. 1 and 2 continuous filaments 3 are passed between a pair of rollers 4, 5 and another pair 6, 7 rotating at a higher speed. The upper rollers are pressed on the lower rollers by an adjustably loaded bar 8 and rod 9. The lower rollers are made of steel and surfaced with a pattern of grooves with upstanding protuberances as shown enlarged in Fig. 3. The upper rollers are covered with leather or rubber 12. To avoid excessive local wear, the thread is reciprocated between the pairs of rollers by a guide tube 10. The staple fibre thread produced is wound and twisted on a ring spinning device 15, 16. Specifications 410,805, 411,506, 416,864, and 417,325 are referred to.
