Title: Improvements in or relating to circular latch needle knitting machines
IPC: D04B15/28
Filed: 1945-04-03
Abstract: 595,279. Knitting-machines. WILDT & CO., Ltd., HOLMES, H. H., and WIDDOWSON, A. H. April 3, 1945, No. 8169. [Class 74 (ii)] In a combined yarn feeding and latch controlling mechanism of the kind involving a latch detainer and two or more movable feeders, one or more of which feed ground and plating yarns conjointly to the needles, the latch detainer is controlled as to its movements to and from the operating position by one or more of the feeding members of the yarn feeding arrangement. A pair of feeders 1, 2 for ground and plating yarns, an additional yarn feeder 3 and a rubber thread feeder 4 are all pivoted on an axle 7, and a latch detainer 5 is pivoted at 25. When feeder 3 or 4 is swung into operation in substitution for the feeders 1, 2, either a pin 19 on the arm 15 of the feeder 3 contacts the back edge of the latch detainer, or the leading edge of feeder 4 contacts a pin 24 on the latch detainer ; and the latch detainer is thereby swung to an inoperative position against the action of a spring 26. The arms carrying the feeders are spring biassed to swing the feeders into operation and are swung in the opposite direction at the appropriate times by cams mounted on a shaft 53, acting through slides and linkages, and rotated by patterncontrolled mechanism. The feeder 2 consists of a plate formed with a slot 2a to permit change in the relative positions of ground and plating yarns during reciprocatory knitting. The feeder 3 consists of a slidable element 3a which, when inoperative, is retracted by a spring, to avoid fouling the feeder 4 but which is projected by an adjustable stop 27 when in the operative position. Adjustable stops 31, 32, determine the operative positions of feeder 3 and latch detainer 5. The feeders 1, 2, are swung in, initially, beyond the normal feeding location (up to an adjustable stop 30) and are returned by the outgoing feeder to the feeding position by means of an adjustable contact (e.g. screw 29) associated with one or each of the feeders 3, 4. A conventional yarn trapping and severing device 90 is provided. In a modification, Fig. 7, a projection 2b on the feeder 2 cooperates with a tail 5b on the latch detainer to swing the detainer to the inoperative position, against the action of a spring 26, as the feeder is withdrawn.

Title: Partial oxidation of hydrocarbons
Inventor: OLENBERG HARRY
IPC: C07C29/52
Filed: 1964-02-27
Abstract: An improvement in a process for the preparation of oxygenated products, especially cyclohexanone and cyclohexanol, wherein a hydrocarbon is selectively oxidized in the presence of a boron compound so as to form a reaction mass containing a boron ester and unreacted hydrocarbon, wherein the reaction product is hydrolysed so as to obtain boric acid and hydrocarbon oil containing unreacted hydrocarbon and oxygenated products, and wherein said boric acid is recovered as a solid and used in a subsequent hydrocarbon oxidation reaction, which improvement comprises washing said recovered boric acid so as to maintain a high selectivity to said ester in said subsequent oxidation.  The washing liquid may suitably be water, the starting hydrocarbon, oxygenated products obtained in the oxidation, or purified "hydrocarbon oil" (i.e., the organic liquid phase resulting from the hydrolysis of the reactor effluent, which has been purified by caustic washing or distillation). Where cyclohexane is the starting material the order of preference of the washing liquids is (1) purified cyclohexane-oil, (2) cyclohexanol and/or cyclohexanone, (3) water, (4) cyclohexane.

Title: Detection of changes in the material of a product by means of detection of heat radiation emitted from the product
IPC: G01N21/89
Filed: 1973-02-20
Abstract: 1415545 Scanning hot materials for faults therein AGA AB 20 Feb 1973 [14 March 1972]  8356/73 Heading G1A In a device for scanning hot infrared radiation emitting material, Fig. 1 (not shown), for faults &c. the part of the material being scanned by a detector is covered by an apertured screen 12 which is maintained at substantially the same temperature as the material and which is treated to have an emissivity of close to 1, the scanning of the material being effected via the aperture. The scanning mechanism is preferably arranged to receive radiation being emitted at an angle to the material, Fig. 2 (not shown), thereby reducing the effect of ambient radiation passing via the aperture to be reflected off the material and received by the scanning detector. The output of the scanning detector 11 is fed via a video amplifier into two sample and hold circuits 14, 15 with relatively long time constants controlled by two gating pulse generators 18, 19 which activate the sample and hold circuits 14, 15 once in each scan so that one receives signals due to the bridge parts of the screen (at either end of the slot aperture) and the other receives signals due to the material itself (plus ambient radiation &c.), the net result being that at the end of each scan the sample and hold circuits have a value equivalent to the mean temperature of the screen or of the material, these signal values are then compared by a differential amplifier 20 which controls a temperature servosystem 21 for maintaining the screen at the same temperature as the material. The signal from the video amplifier 13 is also connected via a voltage divider 23 to one input of a comparator 24 along with the output of the sample and hold circuit 15, as shown, the comparator 24 being controlled by the gating pulse generator 19, and is able to detect defects in the material since it compares the present temperature signals provided by the video amplifier with signals due to the mean temperature of the preceding scan supplied by the sample and hold circuit 15. Whenever a defect is detected a relay 28 is activated to turn on a warning light.
