Title: Improvements in methods of knitting hosiery
IPC: D04B9/46
Filed: 1944-11-17
Abstract: 628,590. Knitting. SCOTT & WILLIAMS, Inc. Nov. 17, 1944, No. 16201/47. Convention date, Nov. 13, 1943. Divided out of 628,526. [Class 74 (ii)] To facilitate recognition of the loopers' rounds formed on the completion of the reciprocatory knitted toe of a stocking, so that they may readily be placed on the points of a looping- machine, the first course of rotary knitting is knitted of the same yarn as the last course of reciprocatory knitting. The stocking is knitted of two yarns Y, Y<SP>1</SP>, simultaneously, as is described in Specification 628,526, and the toe is knitted by reciprocatory knitting of the two yarns such that two courses of one yarn alternate with two courses of the other yarn. On recommencing rotary knitting, the first course 2 is of the same yarn as the last course 1 of reciprocatory knitting and is knitted as a loose course for the purpose of forming loopers' rounds. The second course 3 is knitted of contrasting yarn and also as a loose course. Thereafter rotary knitting continues normally using the contrasting yarns in alternation. The courses 2, 1, being the last two adjacent courses knitted of the same yarn, permits the loopers' rounds, formed by the first course 2 of rotary knitting, to be easily recognised and readily selected for positioning on a looping-machine.

Title: Improvements in or relating to straight bar knitting machines
Inventor: WOODCOCK GEORGE SYDNEY
IPC: D04B11/00
Filed: 1961-05-05
Abstract: 1,001,591. Knitting machines. WILLIAM COTTON Ltd. May 3,1962 [May 5, 1961], No. 16296/61. Heading D1C. Needle selection for patterning on a straightbar machine is achieved by mounting the needles 1 in the needle bar 2 such that they are only frictionally held and are capable of being retained in a lowered position by control elements 17 which selectively engage over the heads of the needles. When the needle bar is raised those needles engaged by their selecting elements 17 are held stationary whilst the needle bar frictionally slides up their shanks. After a yarn has been fed to the raised needles the needle bar is lowered to cause the operative needles to knit the yarn whilst a stop member 15 supports the needles which have been retained in a lowered position so that the needle bar slides down their shanks. Prior to the next course a fresh selection of the elements 17 is made. If a two colour pattern effect is required needles which are rendered inoperative in one course by being retained in a lowered position knit in the next course and vice versa. The control elements are mounted to slide in the sinker head adjacent the sinkers and are selected by a pattern drum 18 rotated and advanced to effect selection of the elements by mechanism operated by cams on the main cam shaft. The front edge of the control elements serves as the presser edge for those needles which are caused to knit. Alternatively, the needles may be caused to effect tuck work or held loops.

Title: Improvements in or relating to the production of combustible gases from hydrocarbons
IPC: C01B3/30
Filed: 1951-07-13
Abstract: 701,820. Generating oil gas. HUMPHREYS & GLASGOW, Ltd., and WILLIAMS, N. H. June 25, 1952 [July 13, 1951], No. 16644/51. Class 55 (2) In a process for making gas from liquid or gaseous hydrocarbons by reacting them with an oxidizing gas e.g. CO 2  or steam, in the presence of a readily oxidized and reduced catalyst, catalytic material rendered inactive by carbon deposited thereon is withdrawn from the reaction zone and regenerated by passing it, together with a gas containing free oxygen, through a regenerating zone, the carbon being burnt and the thus heated catalytic material being returned to the reaction zone. In one form, the apparatus consists of a reaction vessel 1, filled with a previously heated catalytic material comprising, for example, iron and nickel oxides. Steam and a hydrocarbon oil or gas enter vessel 1 through pipes 2 and 3 respectively, the oil gas generated discharging to storage through pipe 4. Carbon-contaminated catalyst is withdrawn continuously by a rotary valve 6 and is elevated by a mechanical lift 9 to pass through a valve 10 into a regenerating vessel 11 which is connected by a neck 5, sealed by steam from a pipe 7, to the top of vessel 1. Air from a blower 15 enters the top of vessel 11 and passes down with the catalyst, burning off the carbon thereon and thus heating the material to the reaction temperature required in the vessel 1. If this combustion does not generate sufficient heat, oil may be admitted through a pipe 18 to burn with part of the air in a chamber 13. The amount of air flowing through chamber 11 and its time of contact with the material are adjusted so that the carbon is burnt but the material is not further oxidized. The combustion gases discharge through a pipe 12 and pass through heat exchangers 17 for the combustion air and 20 for the reaction steam. In a modification, Fig. 2 (not shown), the reaction between the oil and steam is conducted in a fluidized bed of the catalyst and the regenerator zone consists of a standpipe up which the carbon contaminated catalyst is carried by the combustion air.

Title: Improvements connected with electric transformers
IPC: H01F29/04
Filed: 1927-06-24
Abstract: 296,839. English Electric Co., Ltd., and Ayres, W., E. M. June 24, 1927. Systems depending on static transformers.- Relates to regulating the voltage of a transformer by tappings associated with an induction regulator by means of whch the voltage may be gradually changed from one tapping value to the next, and consists in employing an induction regulator such as that described in Specification 270,839 in which the rotor and stator windings are in series and associated with a change-over switch whereby excitation may be applied to either winding so that a voltage may be added or subtracted, the regulator being interconnected with the tapping switch. The tappings 1 - - 7 of the transformer secondary 8 are shown connected to correspondingly numbered fixed contacts on a drum controller having also fixed contacts 26, 27 connected respectively to the windings 19, 20 of an induction regulator. Excitation is applied to one or other of these windings by a winding 23 on the main transformer through a change-over switch comprising a slip ring 21 and a divided ring 24. The moving contacts 10 - - 18 of the controller are arranged and interconnected as shown so that when the fixed contacts occupy the position I, the whole voltage of the winding 8 with the maximum voltage of the induction regulator is applied to the load terminals 28, 29. A reduction of voltage is produced by rotation of the induction regulator until its voltage reaches zero whereupon the change-over switch associated therewith automatically reverses the excitation after which further movement increases its voltage to a maximum in opposition to the voltage of the winding 8. At this point the net voltage is equal to the voltage of the winding 8 up to the tapping 2, and the interconnection between the regulator and the tapping switch causes the contact 11 to engage the contact 2 thus bringing the tapping 2 into use. Further movement of the regulator brings into operation the tapping 3 by engagement of the contacts 3, 12 at the position II, and at the same time again reverses the excitation of the regulator by operation of the change-over switch thus maintaining substantially the voltage of the tapping 2. Further gradual reduction of voltage is then possible by movement of the regulator causing the cycle to be repeated to the position III. Instead of mechanical switchgear, contactors operated electromagnetically may be employed. The switchgear may be housed in the transformer tank or in a separate tank.
