Title: Improvements in and relating to circular knitted stockings
IPC: D04B1/26
Filed: 1962-01-29
Abstract: 989,186. Knitting. M. NEBEL, and E. NEBEL. Jan. 29, 1962 [Feb.18, 1961; June 10, 1961], No. 3359/62. Heading D1K. A stocking comprises circular knitted fabric Fig. 1, which consists of courses (a) of stitches and tuck loops formed by one thread and courses (b) of held stitches and locking stitches, the thread length of course (b) being approximately 70% or less of course (a) so that, when the tuck stitches are formed, the held stitches are drawn up to match the held loops additional thread being derived from the remaining stitches which are reduced to form the locking stitches which appear in successive wales in successive courses (b). Alternatively, Fig. 2, instead of the tuck loops and held stitches forming tuck stitches the tuck loops are knitted with locking stitches of course (b) to form double thread stitches. Tuck loops may be more widely spaced than every second wale e.g. every third wale, Fig. 4, so that single thread locking stitches are formed as well as double thread locking stitches in the fabric shown partly in dotted lines. The thread length of course (b) may be 60-65% or as little as 45% of that of course (a). The overall size of the stitches may be diminished as the stocking is knitted but the ratio between the thread lengths of the courses may be maintained, increased or decreased. Plain courses (c) may be inserted following a course (b), Fig. 3, in which either tuck stitches are formed or the tuck loops are knitted with stitches of course (c) to form double thread stitches. The present fabrics may form the whole stocking including the toe and/or heel or may form a ladder stop band at the toe when the rest of the stocking is of ordinary fabric. A reinforcement thread may be knitted with course (a) or course(b). Courses (a) and (b) may be of different materials e.g. course (b) may have the higher shrinkage. Otherwise course (b) may be synthetic false twist, bulked or crimped yarn and course (a) synthetic pre-shrunkyarn. Specifications 989,187, 989,188 and 989,189 are referred to.

Title: Improvements relating to gravity filters
Inventor: AITKEN ROBERT WILLIAM
IPC: B01D24/20
Filed: 1962-01-30
Abstract: 966,394. Filters. CANDY FILTER CO. Ltd. Jan. 30, 1963 [Jan. 30, 1962], No. 3524/62. Heading B1D. In a gravity filter in which a granular filter bed is disposed above a floor incorporating means for collecting filtered liquid and for distributing cleansing liquid, an upward flow of cleansing liquid is passed through the bed at a rapidly pulsating rate so that the filter bed is caused alternately to expand and contract by amounts which are insufficient to cause filtering media to be carried away with dirt entrained in the cleansing liquid. In one embodiment, Fig. 1, a rapid gravity filter incorporates a rectangular container 1 holding filter bed 2 of e.g. sand or anthracite supported on grid 3 forming the floor of the container. Sill 4 forms with one wall a trough 6 for disposal of cleansing liquid. The filter is cleaned by delivering cleansing liquid from a pump or raised tank (not shown) via pipe 7 to underdrain 5. The otherwise steady flow of liquid is pulsated by operating a reciprocating plunger, diaphragm or air-vessel 8 at e.g. 25-200 pulses/minute. The momentary variations in pressure under the filter bed and corresponding variations in flow rate cause alternating expansion and contraction of the bed. Pipe 7 is of such length that the flow of liquid from pump or raised tank is unaffected by the variations in pressure. In a modification, Fig. 2, the reciprocating member 8 is connected to underdrain system 5 by a separate pipe 9.

Filed: 1923-02-07
Abstract: In a cyclic process for the extraction of copper, the copper sulphate obtained from the copper-bearing material is treated in presence of sulphurous acid with a mixture of sulphuric and hydriodic acids obtained by treating iodine with sulphurous acid. Cuprous iodide and sulphuric acid are obtained.  The cuprous iodide may be treated with a solution of sodium carbonate or hydrate to obtain sodium iodide which is heated with an oxidizing agent such as manganese dioxide to liberate iodine.  The sodium manganate thus obtained is treated with water to obtain manganic oxide and sodium hydrate.ALSO:Copper-bearing material is treated with sulphuric acid to obtain a solution of copper sulphate from which any silver may be precipitated as chloride and removed.  The solution is treated in presence of sulphur dioxide in excess, with a mixture of sulphuric and hydriodic acids obtained by reacting upon iodine with sulphur dioxide and water.  The cuprous iodide is separated, leaving sulphuric acid which is used to treat the copper-bearing material as above described the process being cyclic.  The cuprous iodide is heated in presence of oxygen or copper oxide or both to obtain iodine and cupric or cuprous oxide, or is treated with solution of sodium carbonate or hydrate to obtain cuprous oxide and sodium iodide.  The sodium iodide is heated with an oxidizing agent such as manganese dioxide to obtain iodine, the manganate being then decomposed by water to obtain caustic soda and manganic oxide which may be reconverted into the dioxide in known manner.

Filed: 1976-01-30
Abstract: 1512174 Repairing and retreading tyres VAKUUM VULK HOLDINGS Ltd 30 Jan 1976 [31 Jan 1975] 03838/76 Heading B7C In a method of repairing or wholly or partially retreading a tyre in which unvulcanized rubber has been applied to fill a damaged portion or to attach a tread or tread portion to the tyre, a hollow needle is inserted into a part of the repair or retread area enclosed from the atmosphere and suction is applied to the needle to remove gaseous matter from within the area, the needle is removed and the puncture opening made by it sealed, and then the repair or retread area is heated to vulcanize the unvulcanized rubber. In the repair method illustrated in Fig. 1 a damaged portion 2 is covered by a flexible rubber cover 3a after being filled with unvulcanized rubber, and the cover is then stuck at its edges 5 to the tyre by using unvulcanized rubber. The cover is then punctured by a needle 16 and gaseous matter is extracted by suction which at the same time causes the cover 3a to be drawn down tightly on to the repair area. When gas extraction is complete the hole made by the needle is sealed by a piece of unvulcanized rubber 10d which may be placed in position prior to insertion of the needle as shown or after the needle has been removed. A cover stuck to the tyre may also be used to cover a tread or tread portion and unvulcanized rubber adhering the tread or tread portion to the tyre-Fig. 2, not shown, the procedure then adopted being the same as in the repair method described above. In an alternative method of retreading unvulcanized rubber members 10b, Fig. 3, of wedge section are inserted between the edges of a tread band 11 and a layer 10 of unvulcanized bonding rubber so as to form spaces 18 between the band 11 and layer 10, and then the needle is inserted through the layer 10 of a member 10b into one of the spaces 18. Extraction of the gaseous matter in the spaces 18 then causes the band 11 to be drawn down tightly on to the layer 10 and members 10b.

Abstract: 971, 894. Resistance bridges. COUNCIL FOR SCIENTIFIC & INDUSTRIAL RESEARCH. Jan. 31, 1961 [Jan. 15, 1960], No. 3979/64. Divided out of 971, 893. Heading G1U. An A.C. bridge circuit having transformer ratio arms is arranged so as to substantially eliminate from the potential balance circuit, the effect of the resistance of the leads to the unknown resistor. The bridge may be used with the resistance thermometer described in Specification 971, 893. Fig. 1 shows one embodiment in which the A.C. source is connected direct to one end of the unknown resistor so that the supply current does not flow in the balance circuit of the bridge and a transformer T2 is provided which injects into one of the ratio arms a voltage equal to that developed across the other lead to the unknown resistor, thus cancelling the effect of the resistance of this lead. A similar embodiment is described using a second transformer in the case where the resistor Y is located at a distance from the bridge circuit e.g. with the unknown resistor. Fig. 3 shows an embodiment in which the current supply to the measuring resistors X and Y is via transformers Sx and Sy while the remainder of the bridge circuit can be located remote from the resistors, the high impedance of the transformer ratio arms preventing the resistance of the connecting leads having any substantial effect on the measurement. In an alternative form the resistors are connected to the bridge circuit via transformers Sx and Sy Fig. 4 so that the supply circuit is isolated from the measuring circuit. Alternatively in a modification of Fig. 4 the secondaries of transformers Sx and Sy are connected in series opposition, one transformer having an adjustable tapping which is varied until the secondary voltages cancel indicating balance, Fig. 5 (not shown). Alternatively Fig. 4 may be modified to measure average temperature of a region by employing a number of resistance thermometers connected in series in the arms of the bridge, Fig. 6 (not shown)
