Title: Improvements in thread cutting temples for automatic filling replenishing looms
IPC: D03D49/70
Filed: 1925-08-27
Abstract: 257,733. British Northrop Loom Co., Ltd., (Northrop Loom Co.). Aug. 27, 1925. Weft, cutting. - The temple thread-cutfter 23, 24, Fig. 6, of an automatic weft-replenishing loom is normally held inoperative by a latch 29 controlled by a device on a fixed part of the loom, which is operated by the detector-mechanism to release the cutter for a number of picks while it is gradually shifted, by connections from the lay, back to inoperative position. The lever 29 has a pin-and-slot connection with a lever 32, which is movable against a spring 35 by a Bowden-wire connection 75 with a controller lever 47, Fig. 2. The lever 47 coacts with a cam-disc 45 having depressions 46; when the lever 47 enters a depression, the lever 29 engages the pin 31. A ratchet 49 on the disc 45 is operable by a pawl-lever 55, but is mutilated at 50 so that the ratchet is not actuated when the lever 47 is in inoperative position. The lever 55 is pivoted to an adjustable twopart clamp on the lay 4 and is slotted to engage a pin 56 on the frame. When filling-replenishment is indicated, the shaft 10. Fig. 1, is rocked so that its arm 11 swings the shuttle-feeler 12 about its pivot 13. This movement raises a rod 53 pivoted to the shuttle-feeler 12, so that a pawl 51 at its other end engages one of several broad teeth 57, Fig. 2, on the ratchet 49 and partially rotates the ratchet and the disc 45. The lever 47 is thereby raised on to the periphery of the cam-disc, and the cutter-blade 24, 25, Fig. 6, is released, so that the arm 25 is shifted into the path of the lay and the cutter is thereby actuated. The pawl 55 now engages the ratchet and gradually rotates it until another mutilated poition 50 is reached, when the lever 47 drops into a corresponding depression 46 and the cutter is latched into inoperative position. The controller is mounted on a plate 38, Fig. 2, adjustably fixed to the loom-frame. The disc 45 is freely mounted on a spindle 42 and is positioned by a spring 'surrounding the spindle between the disc and a cover-plate 67, Fig. 1, which also positions the other members of the controller.

Title: "improvements in or relating to flexible, porous, metallised sheet material"
Inventor: BRACE ROY DRAKELEY
IPC: D06Q1/04
Filed: 1953-08-04
Abstract: Fabrics, paper, and fibrous webs of animal, vegetable, or mineral fibres are metallized by first applying an adhesive by means of a spraying apparatus, a tipping or printing roller and thereafter applying a thin, porous layer of metal by vacuum deposition.  The adhesive is so applied that a vapour-permeable metallized fabric is obtained, e.g. only upstanding fibres or portions of the fabric structure are coated, the majority of the interstices being left free.  In using a spraying apparatus as adhesive applicator, it is adjusted so that the adhesive has dried to the point of being just tacky by the time the droplets reach the backing.  The adhesive may be applied to selected areas only of the backing.  The treatment of a viscose rayon fabric is referred to.  Specification 722,409 [Group VIII] is referred to.

Patent GB-479488-A (GB)
Title: A process for the refining of lignite tar, shale tar, peat tar and the like
IPC: C10C1/18
Filed: 1936-08-04
Abstract: In a process for working up crude tars, such as lignite, shale or peat tars, the tar is topped to about 260 DEG  C., and the residue treated at above 50 DEG  C. with a selective solvent preferably low boiling phenols, whereby non-paraffinic components, asphalts and resins are removed.  The phenols may be used alone or diluted with water, esters, ketones, or lower alcohols which decrease the solvent power of the phenol.  If the topped tar is dewaxed or diluted with benzine or similar solvent a lower extraction temperature, e.g. 30 DEG  C. is used.  In an example, the crude tar is topped to about 200--220 DEG  C and then to 260 DEG  C.  The first fraction is freed from the phenols and cresols which it contains, and these are used as the selective solvent subsequently.  The residue of this fraction is used as a motor fuel, and the second fraction (220--260 DEG  C.) after refining, e.g. with sulphur dioxide, is used as a Diesel fuel. The topped tar is then extracted at 50--60 DEG  C. with the phenols obtained from the first fraction mixed with about 10 per cent of water.  The mixture is separated in a centrifuge and the raffinate is freed from the phenol by distillation in vacuo.  This oil is then de-waxed by chilling and separating the wax.  The wax may be further purified by sweating and treating with sweated wax with ash-free coke.  The de-waxed oil may be further extracted with selective solvent to form lubricating oils, or submitted to cracking or hydrogenation to form motor and Diesel fuels.  The extracts obtained are preferably detected with benzine and the precipitated material is separated. Phenols and benzine are recovered from each fraction. This raffinate may be used as Diesel fuel, and the asphaltic extract after removal of wax, if any, is worked up into a road-surfacing material, for example by oxidation or by distilling off the light oils.

Title: Improvements relating to variable-pitch airscrews
IPC: B64C11/36
Filed: 1939-07-26
Abstract: 534,529. Variable pitch propellers. DE HAVILLAND AIRCRAFT CO., Ltd., and THOMAS, F. M. July 26, 1939, No. 21723. [Class 114] Energy is accumulated during pitch-change operations outside the normal range of pitch variation, and is used to effect such abnormal pitch variations, e.g. feathering and unfeathering. The pitch may be changed by a piston 7 carrying racks engaging pinions on the blades. This piston is actuated by oil under pressure supplied through an annular space 22 in the screw shaft, between a fixed seating 21 and a seating on a piston 16 which is moved against a spring 17 by oil under pressure supplied through a conduit 18. When the pressure in the conduit 18 is cut off, the spring 17 returns the piston, and the seats 20, 21 are pressed into contact, the entrapped oil holding the piston in position against a spring 9, and also when the blades are moved into feathering position, against a spring 10. On reopening the lock 20, 21, the release of oil pressure allows the springs to return the blades to normal pitch. The oil pressure is used indirectly to press the rack and pinion into contact. Specification 509,298 is referred to.
