In the machine described in Specification 699,851. the end of the recoiling combed tuft at feed-back is held against the surface of detaching roll 7 and then caused to pass between the wall of a housing 9 and a baffle 139, so that it is shielded from the combing cylinder 1. by an induced waste-removing airdraught passing through holes 261 in a channel member 255 running the length of the machine frame and connected to a suction fan delivering to a waste receptacle. To determine the percentage of waste removed by any combing head, a wire screen 272 is inserted over the corresponding hcle 261 and the weight of waste caught thereby is compared with the weight of stock fed to the machine in the same interval of time. Specification 699,860 also is referred to.

Filed: 1974-04-10
Abstract: 1471420 Data transmission; multiplexing KOKUSAI DENSHIN DENWA KK 10 April 1974 [12 April 1973] 15869/74 Heading H4P An arrangement, particularly for facsimile transmission wherein other information may be transmitted when bits in blocks all have the same value, comprises a first store and signal change detecting device which provides an inverted signal on presence of change in present and previous blocks, whereby the present block is sent if change is detected together with a flag bit(s), but other information is sent, with different flag bit(s) if nil change(s) are detected. At a receiver, the flag bit(s) determine destination of incoming information. An analogue or digital signal on terminal 101 is sampled at 2, the result being passed to a 4-stage shift register 4 which when full is examined, together with the last bit in a shift register 7 by a bit change detector 5. Provided at least one bit differs from the remainder, flip-flop 11 is set to 1 and gate 6 transfers content of 4 to 7 and thence to 8 for transmission with a flag bit 0. With no change, flip-flop 11 is set or remains at 0 and other information from memory 10 is passed through 8 and transmitted together with a flag bit 1. If there are a plurality of sources of other information, an appropriate number of flag bits will be transmitted. At the receiver a flag bit detector (308) Fig. 2 (not shown) energizes an appropriate gate, e.g. (204, 206) to divert incoming blocks appropriately. A shift register receiving the main transmission has a control circuit to insert untransmitted facsimile &c. bits. The arrangement permits additional transmitted information during periods which would otherwise be occupied by redundant bits.

Abstract: 578,845. Projectiles; bombs; grenades. TAYLOR, J., WHITBY, G. F., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. Nov. 11, 1942, No. 15978. [Class 9 (i)] Projectiles, bombs and grenades for use against armour plate, of the kind wherein the explosive is loaded under pressure in to a two-part casing the fore-part of' which is thin enough to collapse readily on impact, have the two parts connected without relative rotation and with the interposition of a resilient washer, so that relative longitudinal displacement is possible to accommodate the expansion of the explosive under temperature increases. The Figure shows a hollow-charge projectile, the hollow end of the charge 3 being lined with a coned metal plate 4, upon the rim of which bears a flange 8 on the front part 1 of the projectile casing. The rear part 2 of the casing is of larger diameter than the part 1 and has a screw thread 11 rolled on it to receive a flanged screwed ring 12. Between the flange 13 of the ring and the flange 8, a resilient felt washer 10 is interposed. A V-section sealing ring 14 prevents escape of the explosive past the rim of the plate 4 into the space occupied by the washer, and a strip of adhesive tape is so placed as to prevent metallic contact between the two parts of the casing adjacent the flange 8.

Title: Improvements in methods of and apparatus for moulding tiles and the like
IPC: B28B1/00
Filed: 1949-06-16
Abstract: 672,934. Moulding tiles; shaking-machines. GRINDROD, P. W. June 14, 1950 [June 16, 1949], No. 16107/49. Class 87(ii) [Also in Group X] A method of moulding cement tiles and like articles comprises the steps of forming a -fluid mixture of facing material, depositing a layer of the facing material on the base of the mould and ventilating the base of the mould and vibrating the base of the mould to consolidate the solid part of the mixture thereon, adding a backing layer of a relatively dry cement mixture, and finally vibrating the base of the mould to unite the facing and backing layers, the mixture for the backing layer being such that it absorbs all the free moisture from the facing layer. A tile is moulded on a pallet 35 which rests on a platen 17 and is lowered part way in a surround 10, forming the sides of the mould, by the partial depression of a lever 22, to which the platen is joined by a link rod 20, against the resistance of springs 16. The mixture of facing material comprising equal volumes of cement and aggregate with enough water to render the mixture fluid is poured on the pallet and levelled off. The aggregate is material which will take a polish, e.g. granite or marble chips. The layer 22 is then fully depressed and the pallet lowered to the bottom of the surround 10. A pneumatic vibrator 30, fixed to the underside of the platen 17, is then set in motion to consolidate the mixture 36 on the pallet. When liquid is seen to rise to the surface of the mixture the vibration is stopped and the remainder of the space in the mould is filled with a mixture 37, which is levelled off, this backing mixture comprising equal volumes of cement and aggregate with only so much water as will render the mixture coherent under pressure. the aggregate being sand and shingle. The vibrator 30 is operated again till moisture is seen to rise through the layer 37, which absorbs it. The lever 22 is released and the springs 16 push up the platen 17, which lifts the pallet above the top of the surround 10 so that the tile can be removed on its pallet. The lever 22 passes through a slot 25 in a latch plate 24 and is held in its bottom .position by a lateral lever 26 at the bottom of the slot and in an intermediate position by a pivoted stop bar 27 hanging vertically. When the stop bar 27 is horizontal the lever 22 can be fully raised. The thickness of the tiles can be adjusted by altering the length of the link rod 20, and the relative thicknesses of the layers 36, 37 can be controlled by adjusting the length of the stop bar 27. The platen 17 has recesses cut back from its edge to facilitate the removal of the pallets from it.
