Title: Improvements in automatic package-winding apparatus for use in conjunction with textile machinery
IPC: B65H67/04
Filed: 1951-05-15
Abstract: 699,264. Sliver &c. winding machine. T.M.M. (RESEARCH), Ltd., WATSON, W.H., and MORRIS, R May 13, 1952 [May 15, 1951], No. 11306/51. Class 120(ii) An automatic package-winding machine comprises in combination with a friction driving roller 36, a carrier 27 for a bobbin 28, means; e.g. a block 23, at one end of the carrier for mounting it for free rotation with the bobbin in driving contact with the roller 36, said means being capable of traversing away from the roller 36 as the package grows and of returning to the initial position when the package is doffed, as by rollers 24 on the block 23 engaging between vertical rails 22, means for withdrawing the carrier 27 from the bobbin when the package is complete, and charging mechanism for thereafter delivering an empty bobbin to the carrier preparatory to the commencement of the next cycle of operations. When the package is complete, the shaft 35 driving the friction rollers 36 is stopped and a shaft 46 is set in motion, which, through gearing 44, 45 drives a screw 42 to traverse a plate 37 to withdraw the carrier 27 furnished with springs 29 from the package which falls into a suitable receiver. The carrier 27 then drops under gravity to its original vertical position and reversing gear brings the plate 37 and carrier 27 back towards winding position. During this return movement, a gate 53, closing the bottom of a magazine 51, is tripped by a lever 58 carrying a roller 66 to allow the lowermost empty bobbin 52 to fall on to limb 55 of the charging slide 54. The lead screw 56 is now rotated to cause the slide 54 to convey the bobbin 52 thereon and to place it over the carrier 27 in the adjacent winding unit. The sliver extending between the driving roller 36 and the doffed package is then lifted by a lever 60 co-operating with a slot 71 so that it becomes nipped between the empty bobbin 52 which is being donned and the flange 271 of the carrier 27. The lead screw 56 is now reversed and the charging slide 54 is withdrawn into a position to receive the next empty tube 52 from the magazine 51. The shaft 35 is then set in motion to rotate the new bobbin 52, break the sliver extending to the doffed package and begin a new wind. Any suitable timing control means for the operation of shafts 35 and 46 and lead screw 56 may be employed. The delivery point E of the sliver is maintained stationary and traverse along the bobbin is effected by reciprocating the frame 20 to which winding units are attached.

Filed: 1950-05-09
Abstract: 672,844. Photographic developing apparatus. EISBEIN, W. May 9, 1950 [May 13, 1949; June 13, 1949], No. 11545/50. Class 98 (ii). A device for developing flexible photographic sheet material and for simultaneously transferring an image on to flexible transfer sheet material by moistening the materials with a developer liquid and by subsequently pressing the materials into contact one with another, comprises a container for the developer liquid and spaced guiding means mounted in the container and determining superposed curved guideways for two or more such sheets, the guideways having their inlet ends above the intended level of the liquid and extending from the inlet ends downwardly, whereby the sheets will be immersed in the liquid, and having their outlet ends adjacent a roller arrangement which presses the sheets together. As shown, the liquid is held in a casing 1 having a lid 2; a removable frame 3 has a flange 4 resting on the rim of the casing 1. Frame 3 supports four parallel plates 5, 6, 7, 8 forming a guideway, which project through the casing and lead below the liquid surface to a pair of rollers mounted in the frame 3, the plates and the sides of the casing being apertured to allow the liquid to pass therethrough. The rollers are geared together and driven by an electric motor 24 through a shaft 23 and a worm gear. Each roller has a metal core 13 and a resilient outer covering 14, e.g. of rubber, and the upper roller is mounted in bearings which are spring-pressed towards the lower roller. The resilient layers may be of different thicknesses. The apparatus is chiefly used in a process described in French Specification 879,995, wherein exposed sheets are wetted with a liquid which activates developing and fixing materials contained in the coating thereof and pressed into contact with coated copying material to which an image is transferred. The copying material may be coated on both sides, and fed between plates 6, 7 at the same time as two exposed sheets are fed between plates 5, 6 and 7, 8 with their coated faces inwards. The plates preferably have corrugations inclined to the direction of travel of the sheets so that they are thoroughly wetted as they pass through the liquid to the rollers, by which they are squeezed together, so that transference of the image takes place and at the same time most of the liquid is squeezed out. The emerging papers are stripped from the rollers by two series of plates 28, 29, mounted to swivel on shafts 30, 31 and pressed tangential contact with the rollers by springs 32, 33, which also serve to guide the papers through an opening 34 in the casing. A tray formed of parallel wires, not shown, receives the papers as they emerge.

When turned from the positior shown to an extent limited by a stop 92, ar eccentric 98 unseats the valve 36 through a push rod 37 and the working cylinder communicates with the exhaust through a passage 103. Subsequent sliding movement to the right until a detent 58 engages a groove 56 closes this passage, and a tapered portion of the valve acts to unseat the valve. 44 through a push rod 45, and pressure liquid passes to the cylinder and through a hole 77 to a recess inside the valve. When the pressure in the working cylinder rises to a predetermined value it unseats a needle valve 78, adjustably loaded by a spring 82, to admit pressure to a chamber 78<1>. Here it acts as a part of the valve of increased diameter to complete its lift and on the valve member 54 to return it. to its initial position. When it is desired to lock liquid under pressure in the working cylinder, the valve 54 is merely moved to the right, so that the valve 44 is unseated. Pressure liquid then passes to the cylinder by lifting the valve 36 and is trapped therein by the valve 36 reseating when the valve 54 is back in the position shown.

Title: Improvements relating to signal storage apparatus
Inventor: PERKINS DENIS GORDON
IPC: H04N9/07
Filed: 1957-04-11
Abstract: 893,951. Radar. ELECTRIC & MUSICAL INDUSTRIES Ltd. July 11, 1958 [April 11, 1957], No. 11871/57. Class 40(7). [Also in Group XL(b)] Simultaneous type colour television signals are derived from sequential type signals by storing successive fields of the latter as a charge pattern on the charge storage electrode of a storage tube 2 coincidently with a biasing stimulus produced by a spot of light which also scans the target storage electrode so that during the second and subsequent field scans the signals derived from the tube consist of the difference between the signals stored during the scan considered and the signals stored during the preceding scanning field together with a constant signal due to the bias stimulus. Such output signals are then combined in adder 3 with the signals being stored during the scan considered the algebraic addition resulting in the production of the signals corresponding to those stored during the preceding scan together with the bias stimulus signal. The latter is removed by a level setting or D.C. stabilizing circuit and the remaining signals, i.e. those stored during the preceding field then occur simultaneously with the signals currently being stored. In the present embodiment the television signals supplied to terminal 1 consist of alternate fields comprising green component video signals and intervening fields comprising red component video signals together with a carrier component amplitude modulated by blue component signals. The green signals are then supplied to terminal 5 either directly from the input at terminal 1 or from the output of adder 3 via switch S1 which "changes-over" at field rate the red and blue signals being likewise simultaneously derived during each field scan and separated out by a L.P. filter 8 and a demodulator 9 on a frequency basis. Other embodiments are described in which the storage arrangement 4 is employed to convert sequential type colour television signals to simultaneous type signals in a system utilizing a colour pick-up tube of the type described in Specification 891,941 (Figs. 2 and 3 not shown) and to produce simultaneous type signals from signals derived from a three field sequential colour television camera (Fig. 4 not shown). The storage apparatus of the invention is stated to be also applicable to radar systems in which it is desired to eliminate components of a signal representing fixed objects. Instead of employing a light stimulus a double beam "reading-writing" tube may be employed one beam being used to "lay-down" the signals and the other to provide the necessary bias stimulus. The scanning of the storage tube(s) and of the connected tubes employed in the embodiments of Figs. 2-4 (not shown) is effected with "spot-wobble" to ensure discharge of the whole area during each field scan period. Specification 657,666 also is referred to.

Title: Improved stimulated emission source of light
IPC: H01S3/113
Filed: 1965-03-19
Abstract: 1,079,793. Lasers. CSF-COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. March 19, 1965 [March 20, 1964], No. 11903/65. Heading H1C. Q-switching in a laser is achieved by including in the optical cavity a body of material whose transparency increases with the intensity of the light incident thereon. In one embodiment, Fig. 4 (not shown), a plate of glass containing semi-conductive impurities and whose transparency depends on the intensity of light passing through it, Fig. 5 (not shown), is inserted in the resonant cavity of an optically pumped ruby laser between the ruby crystal and one of the plane reflecting mirrors of the cavity. At the start of the pumping action, when there is no stimulated emission, the plate is absorptive and the population of the upper energy level of the chromium ions corresponding to the red transition is zero. Due to the pumping by a flash tube the population of this level increases until it reaches the threshold level for stimulated emission to occur. At this instant, Fig. 6A, (not shown), the plate becomes transparent due to the increase in intensity of the light incident thereon and the critical threshold which is determined partly by the transparency of the plate is greatly decreased resulting in the production of a pulse of light. When the population decreases below this new threshold level stimulated emission ceases and the plate becomes opaque again. In order to control the instant when oscillation starts an electric field is applied to the plate 2 parallel to or at rightangles to the transmitted light so as to vary its transmitting power, Fig. 7. A pulse generator 5 is coupled to the lamp 4 for providing pumping pulses and a delay 6 is connected between the generator 5 and electrodes 7 for triggering stimulated emission at the end of each pumping pulse.

Abstract: 1411729 Displays MATSUSHITA ELECTRONICS CORP 18 March 1974 [20 March 1973] 11910/74 Heading G4H In a decimal point display circuit, a register 1, controlled by an adder/subtractor 2, stores the position of the decimal point, the sign of this information being detected at circuit 3 to indicate whether or not the decimal point is beyond the lower limit of the display and accordingly control a circuit 5 to load a counter 4 with the position information in true or inverted form, the counter 4 being decremented by display digit timing pulses to produce, at count zero, a pulse from an AND gate 9 or 10, controlled by circuit 3, to display a decimal point or digit mark respectively according as the decimal point position is or is not within the limit of the display. In Fig. 1, AND gate 10 resets a flipflop 7 which is initially set, so that all the digit marks from the low order of the display up to the required position are energized, i.e. the number of marks energized equals the number of positions below the low end of the display the decimal point is at. Alternatively, the flipflop could be omitted so no more than one digit mark is energized.

Abstract: 547,359. Coating surfaces. BRAND, H. M. Sept. 17, 1941, No. 11914. Convention date, Oct. 30. 1940. [Class 95] [Also in Group XVII] A plastic, slightly elastic composition of natural or synthetic indiarubber and bitumen is disposed in a groove 4, Fig. 1, in, the lid of a container to make sealing contact with the surface 7 of the mouth ring 3. The groove may be first coated with a film of resin, and the composition may be coated after application with a layer 6 of lacquer. The composition is applied by means of the device shown in Figs. 2 and 3 in which the lids are supported by their edges between a fixed rail c and a travelling conveyer band e. The edges are first dipped into liquid resin in a trough bh, then cooled in a tunnel f after which they receive the composition consisting of liquid bitumen and rubber solution in trough bg. Lacquer, if used, is applied in trough bl and the lids are dried in a second tunnel g after which they are heated to soften the composition by a heater h and dried in a third tunnel k and finally drop into a receiver m. The heating causes the bitumen to ooze out from the composition, filling the surface pores of the rubber or penetrating into the lacquer coating if provided. In a modification, formed rubber rings laid on films of resin disposed in the grooves are coated with bitumen contained in the trough bg, the process then continuing as before.
