Title: Improvements relating to flat warp knitting machines
Inventor: PORTER ALLAN WILLIAM HENRY
IPC: D04B27/08
Filed: 1959-04-14
Abstract: 889,738. Knitting-machines. HOBOURNF. N. F. Ltd. April 4, 1960 [April 14, 1959], No. 12666/59. Class 74 (2). The needle bar 23 of a flat warp machine is driven at each drive point from a pair of eccentrics 39, 43 which operate in parallel, eccentric 39 rotating at twice the speed of eccentric 43, through two rods 37, 41 connecting the eccentrics to a cross-head 35, and through mechanism including a bell crank 31 connected to the cross-head at a point 34 between the connections 36, 40 to the two connecting rods, guide bars 45-50 also being driven from the eccentrics through the connecting rods and cross-head and through further mechanism which includes a rod 63 connected to the crosshead at a position 64 on that side of point 40 remote from 36. The distance between points 36 and 34 is twice that between points 34 and 40 and the distance between points 40 and 64 is substantially equal to that between points 40 and 34. The eccentrics 39, 43 have the same eccentricity and are in phase. The bell-crank 31 drives through a U-shaped lever 25 pivoted at 26 to an arm 27 pivoted on a fixed shaft 28. The rod 63 drives through pin and slot connection 61, 62, bell-crank 60 and push rod 58. The arrangement provides that the needles move as in Fig. 6, with a dwell and slight downward movement in their uppermost position, whilst the guide eyes carry out the movement of Fig. 8, which is nearly a mirror image of that of the needles, but displaced from it by 180 degrees. When, say, only two guide bars are used, the guides do not need so long a dwell for shogging at the backs of the needles and simple harmonic motion is preferable. To this end, the rod 63 is detached from the crosshead and, by means of an extension 97 of the rod, is connected at 98 to the connecting rod 41 so that it is influenced only by the eccentric 43. Tongue bar 66 is driven through a U-shaped lever 68 supported on a pivoted arm 69 and pivoted to a bell-crank 72 in turn driven through a crosshead 74 and connecting rods 75, 76 by eccentrics 77, 78 on the shafts 13, 14. The throws and angular relationship of the eccentrics 77, 78 are such that the tongues close the needle hooks just as the needles start to descend at the righthand side of Fig. 6, maintain them closed during all this descent and open them rapidly as the needles start to rise. The sinker bar 82 is, at each drive point, supported on an arm 83 swinging at 84 on an arm 85 mounted on a fixed shaft 86 and linked through pin and slot connection 88, 87 to a lever 89 pivoted on a shaft 32, and connected at 91 to a crosshead 92, in turn connected by rods 93, 94 to eccentrics 95, 96 on shafts 13, 14. Specification 524,969 is referred to.

Title: Manufacture of organo-magnesium compounds
IPC: C07F3/02
Filed: 1936-05-07
Abstract: Phenylmagnesium chloride and its homologues are prepared by heating chlorobenzene or a homologue thereof to boiling under ordinary pressure and in the absence of ether with magnesium or a magnesium alloy having a clean unoxidized surface.  Metal turnings or powders which either are freshly prepared or have been stored in vacuo or in a dry inert gas are suitable for the reaction; when their activity diminishes they may be reactivated by addition of the halide of a metal or metalloid or of an organo-magnesium halide.  An aromatic, hydroaromatic or aliphatic hydrocarbon of high-boiling-point may be present as a diluent or suspending agent, and an excess of the chlorobenzene or homologue may be used for this purpose, the reaction then being interrupted before the conversion of the whole of the magnesium.  The chlorohydrocarbon may be added in portions to the magnesium.  Examples are given of the interaction of chlorobenzene and chlorotoluene with freshly-prepared magnesium turnings, or with ordinary magnesium in the presence of a little cuprous chloride or aluminium bromide or in the presence of a little bromobenzene which becomes converted into its magnesium compound and functions as an activator.  Other activators mentioned are cuprous bromide and iodide, silver chloride and bromide, aluminium chloride, anhydrous magnesium chloride or bromide and phosphorus tribromide; iodine may be present in addition.  Magnesium alloys referred to are those containing 2 per cent of zinc and/or 1 to 2 per cent of copper. Specification 398,561 is referred to.

IPC: F01B17/04
Abstract: 133,043. Gleichstrom - Schiffsmaschinen Ges. K. Schmid & Co. Sept. 29, 1917, [Convention date]. Actuating pumps by fluid-pressure motors. - Relates to uniflow engines of the kind in which the piston has a reduced portion sliding in a guide-cylinder concentric with the working cylinder and consists in using the annular space between the said cylinders as the barrel of the dry air-pump. As shown, the main piston 3 has a reduced part 4 sliding in a guide-cylinder 5. The reduced part is hollow and is in communication with the crank chamber which again is in communication with the condenser. A projection on the main piston carries an annular piston 8 working in the space 7 between the cylinders 5 and 6. When the piston 8 is at the top of its stroke it is above the ports 11 in the cylinder 5 and these are in register with the ports 12 in the reduced part of the main piston, so that the space 7 is in communication with the crank-chamber and the condenser. When the piston 8 descends, the air or vapour trapped by the closing of the ports 11 is ejected through the non-return valve 16.

IPC: B23G1/32
Abstract: 135,602. Muncaster, W. Nov. 28, 1918. Milling screws; attachments for milling.-The work-holding head has an adjustable device for causing axial movement of the work to vary the pitch of the thread cut. The work spindle b is mounted on a slide, which also carries a worm shaft f for rotating the work and a screwed shaft h adapted to be driven by gearing from the worm shaft. A half-nut j carried by an eccentric shaft i is adapted to be engaged with and disengaged from the screwed shaft h, and fits into a recess k<1> of a block k which carries a slipper m adapted to slide on a pivoted bar n which can be fixed at any required angle of inclination to the bed-plate o. The worm shaft is driven through a telescopic rod and two universal joints, and a driving clutch on it is thrown into gear at the same time as the half-nut is geared to the screwed shaft, so that the work slide is moved axially as the work rotates. A collar t on the 'shaft i is pressed upon by the half-nut j to cause automatic disengagement of the drive before the half-nut reaches the end of the slot. The guide bar may be set to zero for plain circular milling. An automatic knockoff may be employed to take effect at any part of a rotation.

Filed: 1929-06-04
Abstract: 339,323. Triggs, W. W., (Multicolor Films, Inc.). June 4, 1929. Drawings to Specification. Toning; colour photography.-In a process for producing colour images, fixed silver images are treated with a basic dye bath and then with a uranium toning and mordauting bath. This treatment is used in a process for producing colour films having colour component images on opposite sides which are simultaneously printed in register from colour component negatives. The printed positive is developed, fixed, and washed, and that side bearing the images printed from the orangered negative is toned blue by application to that side only of an iron toning solution. The film is then passed through successive baths containing (1) water, (2) a basic red dye, (3) water, (4) a uranium toning and mordanting solution, (5) water, (6) hypo, (7) water, and is then passed through drying apparatus. The iron toning solution contains ferric ammonium oxalate, potassium ferricyanide, ammonium chloride, and hydrochloric acid. The basic dye bath is a mixture of two solutions of (a) basic magenta and acetic acid, and (b) auramine and acetic acid. This bath does not affect the blue image if the previous toning is carried to completion, but in conjunction with the following uranium bath gives the orange-red image. The uranium bath comprises potassium oxalate, uranium nitrate, hydrochloric acid and potassium ferricyanide. It clears the dye from the high lights, mordants the dye and also tones the silver image. The colour of the blue image may be modified by not completely toning the image blue so that it may be modified to a bluegreen or green colour by the successive dye and uranium baths.
