Title: Improvements in or relating to knitting-machines
IPC: D04B1/28
Filed: 1920-10-05
Abstract: 152,680. Hemphill Co., (Assignees of Bosworth, G. P.). Oct, 22, 1919, [Convention date]. Void [Published under Sect. 91 of the Act]. Circular machines. - Broad selvedged webs having joined therewith a group of narrow strips, e.g. glove blanks are knitted on circular latchneedle machines with rotary needle cylinders by means of mechanism which comprises knitting- cams, needles with selective butts grouped for strip-production, means for retiring needles prior to selection for each strip, group selective cams for selecting the needle-groups required in knitting successive narrow strips, needle-restoring means and cam controlling devices. Prior to selection of a group of needles for knitting a narrow strip, a withdrawal cam 2 is pressed in towards the needle-cylinder N by a spring. Normally the cam 2 is held out by means of linkwork under control of the pattern gear. The knitting-butts 1<a> are thus engaged and the whole of the needles are elevated out of the way of the knitting-cams, and the lower selective butts 3<a> - - 7<a> are brought up to the level of the groupselective cams 3 - - 7 as shown in Fig. 3. By the pressing in of one of the cams 3 - - 7 when such movement is permitted by the pattern control drum g the corresponding group of needles can be brought down for knitting a thumb or finger strip. The groups of butts, 3<a> - - 7<a> overlap, as shown, to provide for the formation of gussets between the finger strips. Thus some of the needles with butts 4<a> which are brought down by the cam 4 to knit the little-finger strip have additional butts 5<a> and are brought down again when the cam 5 is put in to bring down the needles with butts 5a for knitting the third-finger strip. After all the finger strips are knitted the needles are all restored to the operative level by a cam 8 and a broad selvedged web for the back of the hand and wrist is begun. The hand and wrist portions may also be made by round-andround knitting. The bell-cranks 2r, 8r for the cams 2, 8 are connected by links 2s, 8
 to the same pattern lever 2t so that when one is held out of action the other is pushed in and vice versa. The cams 3 - - 7 are operated by means of a range of pattern-levers g<1> under control of the drum g and connected by links g<3> to bellcranks 3<r> - - 7<r> carrying cam-bars such as 3t. Each of the cam-bars have inclined surfaces such as 3<v>, Fig. 14, which co-operate with notches such as 3<u> in sliding stems such as 3<m>, Fig. 15, of the corresponding cams 3 - - 7. When the cambars occupy the position shown in Fig. 8, the flat surfaces such as 3<x>, Fig. 14, keep the respective cams 3 - - 7 in the outward inoperative positions. When a cam-bar is moved to the left, the incline 3<v> permits a spring to move the stem 3<m> carrying the cam 3 radially inwards towards the needle cylinder.

Filed: 1954-10-01
Abstract: 757,465. Discharge apparatus. WESTING- HOUSE-ELECTRIC INTERNATIONAL CO. Oct. 1, 1954 [Oct. 9, 1953], No. 28325/54. Class 39 (1). An electrode such as the anode 2 of an X-ray tube has an apertured shield electrode 16 in front of or partly surrounding it, and connected to it through an impedance 18. Thus, if high-voltage flash-over occurs in the tube, the current transfers to the shield, and has to traverse the serially connected high impedance, thus preventing its rise to destructive values. Either or both of the main electrodes may be so protected, and the construction may also be applied to high-voltage rectifiers. The connection from the impedance to the shield may be made by way of a metal envelope section 6, as shown, or directly through the envelope wall, or through one of the pinch leads.

Title: Laser
IPC: H01S3/30
Filed: 1970-06-12
Abstract: 1,262,222. Lasers. INTERNATIONAL BUSINESS MACHINES CORP. 12 June, 1970 [30 June, 1969], No. 28502/70. Heading H1C. A gas laser medium 13, Fig. 1, is pumped by pulses from a further laser 1, the carrier frequency of the pulses being swept through the resonant frequency of an optically resonant transition of the gas 13. The pumping laser 1 is a Q switched ruby whose plane polarized output pulses are frequency modulated by an R.F. excited LiNbO 3  crystal before passing into a fluoro-benzene Raman cell 49. The Stokes output from this cell is at a frequency suitable to excite the 4<SP>2</SP>S 1 / 2 #4<SP>2</SP>S 3 / 2  transition in the potassium vapour medium 13, a filter 11 preventing any of the ruby frequencies reaching the vapour medium. The Q switched ruby and the LiNbO 3  modulator are synchronized, Fig. 3 (not shown), so that the ruby output pulses and hence the Stokes output are swept through the above transition in a time short compared with the relaxation time of the transition. This pumping technique, referred to as adiabatic rapid passage, causes super radiant emission from the potassium vapour, without using a resonator. The emission appears to be due to coherenced brightening, i.e. to the passage of an optical shockwave through the vapour, which causes virtually complete population inversion. The pulse width and frequency spread of the super-radiant output depends on the shape of the vapour cell 13 and on the density of the vapour in it. A medium other than potassium vapour may be used, and other transitions, such as a three level transition, may be excited.

Title: Colour developing high impact polystyrene sheet and method of developing colour images inside the same
IPC: B41M5/155
Filed: 1973-06-18
Abstract: 1434586 Polystyrene sheet; laminates OJI PAPER CO Ltd 18 June 1973 [24 June 1972] 28819/73 Headings B5B and B5N [Also in Division D2] A colour developing high impact polystyrene sheet comprises a high impact polystyrene film which has been stretched in at least one direction, a surface layer of the film being treated with an organic liquid, which is capable of dissolving or swelling the polystyrene, so as to form therein numerous microvoids preferably having a mean size in the range 3-20 Á. These microvoids contain acid colour developing agent capable of developing acid-reactive colourless colour forming dye. In the embodiment shown, Fig. 5, a no carbon duplicating sheet incorporates two such polystyrene sheets 63, 68 having microvoid layers 76, 70. The top sheet 61 includes a layer of microcapsules 65 which contain the dye, a second microcapsule/dye layer 74 occurring in the intermediate sheet 62. Thus when pressure is applied to the uppermost face of sheet 60, two coloured records result within layers 70, 76. A releasing agent layer 73 is easily removed from an adhesive layer 71 allowing one sheet 66 to be affixed to, e.g. an article whilst sheet 63 is, e.g. retained as a record. No intermediate sheet need be used (Fig. 1, not shown) or alternatively more than one may be incorporated. The adhesive layer may be omitted. The polystyrene film may comprise 80-98% by weight of polystyrene and 2-20% by weight of a rubber component, e.g. styrenegrafted and non-grafted polybutadiene, styrenebutadiene rubber, an acrylonitrile-butadienestyrene rubber, or natural rubber. The film may be produced from the polystyrene rubber blend by uniformly dispersing, into a polystyrene matrix, fine particles of the rubber component having a mean size of 1-7 Á. The stretching of the sheet causes many of the particles to be elongated and fixed. Treatment by the organic liquid causes these particles to be released which shrink and thereby forms the microvoids, the liquid being removed by evaporation, replacement with a non-solvent or washing. The organic liquid used for treating the polystyrene film may be n-hexane, n-heptane, noctane, benzene, toluene, xylene, tetrachloromethane, methylethyl ketone, methyl-iso-butyl ketone or 1,4-dioxane.
