Title: Improvements in flat-bar knitting machines and the production of fabrics thereon
IPC: D04B11/00
Filed: 1930-05-09
Abstract: 354,374. Straight-bar knitting-machines. JONES, T. H., Breck Hill Road, Woodthorpe, Nottinghamshire, and MILLS, R. K., 3, Edwards Lane, Sherwood, Nottingham. May 9, 1930, No. 14256. [Class 74 (ii).] A machine of tl e Cotton type is provided with needles 1 having double or multiple latches whereby the non- laddering fabric described in Specification 329,098, [Class 74 (ii), Knitting &c.], can be made. The hooks may be made springy to facilitate transfer of loops. Locked or tied stitches are madeat predetermined intervals, the needles being raised for this purpose to a greater extent than for making plain stitches, by a cam 4, so that the yarn can be fed between the latches. The needle bar 2 is reciprocated by a lever device 6 carrying a roller 7 which can be shifted, as required, from the ordinary cam 3 to the cam 4. The roller 7 is controlled by a shaft 19 which can be shifted by edge cams on a shaft driven by the shaft 5. Alternatively the cams 3, 4 may be displaced on the shaft 5 or the latter may move endwise, or clutches may be employed. The sinkers are caused to sink more varn in the formation of a course of locked stitches by pushing in the slur-cocks 21, the rear ends of which are screwed and carry wheels 26. Stops on brackets 24 come into contact with the wheels 26 at the ends of the traverses thus pushing the slur-cocks in or out.

Title: Aromatic dicarboxylic acids and process for making same
Inventor: MIKESKA LOUIS ALOIS
IPC: C07C51/16
Filed: 1957-05-06
Abstract: Aromatic dicarboxylic acids are prepared from diformyl-benzenes which may contain up to four alkyl groups by mixing the dialdehyde with one to ten times its weight of water in an amount sufficient to form a two-phase system, adding sufficient alkali metal permanganate to oxidize the dialdehyde to the acid and sufficient alkali metal hydroxide to convert all of the resulting acid into its alkali metal soap, maintaining the resulting two-phase mixture under reaction conditions and separating the acid from the mixture.  Specified starting materials are the phthalyl dialdehydes and methyl-, 2 : 5-dimethyl- or tetramethyl-terephthalyl-dialdehydes.  Other alkyl substituents specified are tridecyl and heptyl.  Inert diluents such as benzene, toluene or naphtha may be used.  In an example a mixture of 2 : 3 : 5 : 6-tetramethyl-terephthalyl-dialdehyde, sodium hydroxide and water is stirred with cooling and potassium permanganate is added, the mixture is stirred until the permanganate colour disappears and is boiled and filtered. Tetramethyl-terephthalic acid is obtained by acidifying the filtrate. The yield obtained is compared with those of similar oxidations wherein a water/acetone or water/ethanol mixture replaces water in the above process giving a homogeneous mixture.

A variable inductor or transformer comprises first and second magnetic cores 10, 11, each carrying at least one winding, the cores being located on opposite sides of a plane II-II and each comprising a pair of legs terminating at said plane and circumscribable at said plane by a rectangle (13) (Fig. 2, not shown), having sides not differing in length by more than 15%, means mounting the cores for relative displacement about an axis 12, the range of such displacement including an angular position at which each leg of one core is in alignment with a respective leg of the other core, and the cores being so shaped and dimensioned that each closes the magnetic circuit of the other at angular positions within said range. The winding(s) of each core are connected in series aiding relationship such that (as shown) the net field is zero and current passing through the device experiences substantially no reactance. However, on rotation of core 10 through 180 degrees the reactance becomes a maximum, and for angular displacements between 0 and 180 degrees and 180 and 360 degrees the reactance is between zero and maximum, being proportional to the displacement, by virtue of a substantially linear characteristic. A voltage regulator (Figs. 6 and 7, not shown) comprises all four windings connected in series, and a tapping (35) at the connection between the windings of one core and the windings of the other core. The cores may, in a modification, each have three legs, the centre one of which may carry a winding. The windings, in another modification, may be inductively coupled in which case the device constitutes a transformer. In yet another modification, a characteristic other than a straight line may be obtained by an asymmetrical winding arrangement.

Filed: 1924-06-19
Abstract: 218,639. Allyne-Zerk Co., (Assignees of Zerk, O. U.). July 5, 1923, [Convention date]. Single-acting suctionvalveless piston pumps; suction reservoirs. - A gun for supplying lubricant to a nipple 26 comprises a low - pressure chamber 10 with a piston 20 therein adapted to ensure feed of lubricant therefrom to a highpressure cylinder 23, and a high-pressure. plunger 30 adapted to expel the contents of the cylinder 23 by force exerted between the gun and the nipple, such force also effecting and maintaining a fluid - tight joint between the nozzle of the gun and the nipple. The cylinder 23 is provided with a non-return valve 27 and telescopes in the mouth 12 of the chamber 10, communicating therewith through a port 28. The plunger 30 abuts against a cross-pin 29 and extends into the cylinder 23. A spring 32 is arranged between the head 31 of the plunger and a shoulder 24 on the cylinder. The upper part 11 of the container is pressed on to the lower part 10 and contains the cork piston 20, with washers 21, secured on a piston rod 17 extending through a cap 14 and secured to a handle 18. The cap 14 is secured on the part 11 by a wire 16 sprung over a bead 13. The port 28 may be replaced by longitudinal flutes 33, Fig. 4, on the plunger 30. To facilitate the withdrawal of the piston 20 for filling the container, the formation of a vacuum in the container is prevented by a non- return valve 37, Fig. 2, in a passage 34 in the end of the rod 17. Alternatively, the rod 17 may move axially in the piston 20 to open passages 45, 47, Fig. 6. The cylinder 23 is provided with a nozzle 25 having a semi-spherical recess adapted to have leak-proof contact with the nipple 26 at various angles. In operation, the nozzle 25 is pressed against the nipple 26 by pressure on the handle 18. The piston 20 moves inwards to charge the cylinder through the port 28, and, as the pressure is increased, the container slides over the cylinder and the plunger 30 ejects the charge of lubricant under high pressure. Alternatively, the device may be operated by pressing the container towards the nipple, without using the handle. When the pressure is released, the spring 32 moves the cylinder outwards, the vacuum produced therein causing a fresh charge to be drawn into the cylinder and causing the piston 20 to move downwards in the container.

[Class 40 (ii)] Apparatus employing, as in the parent invention, a mask having a number of apertures whereby a variable-area record may be made either in the form of a single track or as a multiple track, the number of tracks chosen being suited to the mean acoustic frequencies being recorded at any particular time, is characterized by the provision in the group of apertures of one which enables a variabledensity record to be produced when required, while means are also provided for automatically moving into the path of the light beam a cylindrical lens or lens system when the variable density record is to be made. In the example shown, the mask is formed as a disc 2 having apertures 2<a>-2<d> which, by rotating the disc into operative position relatively to a beam controlled by an oscillograph 5, enable the different kinds of variable-width records to be made. In addition to these apertures, a rectangular one, 2<e>, is provided. When this is brought into use, rotation of the disc-carrying spindle 2f causes, by means of a cam 9, a spindle 10<a> to rotate and move a cylindrical lens into a position where it concentrates the reflected light beam on a fixed slit 6, which is imaged on the film 8. With this setting, a variable-density record may be made. A notched disc and pawl 14, 15 fix the positions of the spindle 2f in the various settings. The mask may, instead of being a disc, be formed as a drum shaped as a prism &c. or as a cone or cylinder or the like having flattened faces in which the apertures are provided. In a modification, the cylindrical lens may be linked with the means for controlling the oscillograph loop bias current used in one of the arrangements described in the parent Specification.
