Abstract: 1,009,745. Endless conveyers for flat articles, e.g. mail. POSTMASTER GENERAL. May 8, 1964 [May 16, 1963], No. 19185/64. Heading B8A. An endless conveyer 10 of a mechanism for deflecting and for stacking items of mail, e.g. letters &c., comprises links coupled by pins 12 and carrying upstanding plates 13. The plates overlap one another to form side barriers 14, 18 and a slanting barrier 15; the barrier 18 has a gap 19. A letter 25 fed from a pair of rollers 26 is prevented from falling sideways by a channel member 31 as the letter is moved by the conveyer towards a stop 27 which is in alignment with the end wall 28 of a stacker 29 provided with a spring-loaded back plate 30. The conveyer continues to move when the letter reaches the stop and the slanting barrier 15 moves the letter transversely through the gap 19 into the stacker. When the gap again comes around to a position alongside the stacker, either another letter on the conveyer will push back the letter 25 or, if there is no further letter, the letter 25 may be moved outwardly of the stacker to re-engage the barrier 15 and moved back again. The upper edge of a letter is urged towards the stacker 29 by a spring finger 32 and a driven roller 33. A shoot for receiving the letters may replace the stacker 29 in which event the finger and roller may be dispensed with. In Fig. 7, letters are fed alternately on to the two sides of a conveyer 10<SP>1</SP> which has double the capacity of the first arrangement. A roller 26a movable by an operator may be used for pre-sorting the letters. Stackers 29a-29d each provided with a movable stop 27 also provide for sorting. In place of the conveyer utilizing separate links and barrier plates a continuous flexible belt having upstanding strip moulded integrally with or otherwise secured to the letter supporting surface may be provided.

Title: Improvements in the control of travelling filaments, yarns and fibres
IPC: D01H13/12
Filed: 1954-07-01
Abstract: 777,843. Control of travelling filaments, yams, etc.; doubles preventing. BOURNE & CO., Ltd., S., and HILL, R. July 1, 1955 [July 1, 1954], No. 19266/54. Class 120 (2). In a machine wherein a plurality of filaments travel simultaneously along parallel paths there is provided repetitively operating cutter means and guide means for guiding, to the cutter means, any filament on sideways displacement of the latter from its normal path, thus preventing this filament from becoming entangled with an adjacent filament. In the arrangement shown each filament or yarn F is caused to pass over a spool like guide 13 mounted on a metal tube 11. The tube 11 contains a metal cutter bar 12 which is reciprocated longitudinally by a suitable mechanism 14 and carries a pin 15 protruding through a helical slot 16 in the tube 11 into a straight guide track 17 so that as the cutter bar 12 is reciprocated tube 11 is turned to and fro about its axis thereby causing the guides 13 to make cyclic movements. The guide 13 has side discs 19a, 19b each of which has a gate 20 cut into it. When a filament F is unbroken it runs downwardly over the centre part 18 as shown in full lines of the guide 13. If a filament breaks there is a tendency for it to drift sideways to the chain dotted line position where it is caught by one of the deflectors 21a or 21b and passed through the gate 20, it is further deflected by either of the conical parts 22a, 22b into a slot 23a or 23b in the tube 11 where it is cut by the reciprocating bar 12 thus preventing it from becoming entangled with an adjacent filament. In another embodiment the guide spool 13 is replaced by a circumferential groove in the tube 11.

Abstract: 1,046,046. Raising sunken ships. G. D. HENDRY. May 7, 1965 [May 9, 1964], No. 19439/65. Heading B7S. Apparatus for raising a sunken ship comprises a plurality of tubular members 16, 26, 31, 32, 38 (Fig. 1, not shown), connected to one another to form a duct through which pieces of buoyant material, e.g. expanded polyurethane, cork, cord wood or balsa wood, are driven by a weighted plunger 22 downwardly into the hull 14 of the sunken ship to displace water therein, said material being prevented from escaping from the hull by grids placed across any openings therein. Pieces of said material are placed within the uppermost member 16 through an opening or hatch 17 formed therein above a loading platform 11 which is connected to a salvaging vessel 12 by e.g. a chain conveyer. Water within the members 16, 26, 31, 32 is ejected by a pump 34 into a tank 25 whilst the buoyant material is being inserted through the hatch 17. The pieces of said material are supported by a gate member 36 which is pivotally mounted within the tubular member 32 until the apparatus is fully charged, the water in the tank 25 being subsequently returned to the members 16, 26, 31, 32 by compressed air supplied through a pipe P whilst the buoyant material is depressed by the plunger 22 until pressure on either side of the gate member 36 is sufficiently equalized to permit opening of the gate member by an hydraulic ram 37, 37<SP>1</SP> (Figs. 2 and 3, not shown). When the gate member is in the open position the buoyant material 15 is driven downwardly into the hull 14 by the plunger 22 through non-return means 40 constituted by a pair of pivotally-supported plates 41, 42, the downward motion of the plunger being arrested by a tapered stop 44 formed within the tubular member 38 immediately above said means. The plunger is subsequently raised by a cable 20 coupled to a hoist 19. The apparatus is supported by a buoyancy tank 28 which is attached to the tubular member 26 and charged with compressed air through a valve 29 when water therein is to be ejected through a valve 30. The lowermost tubular member 38 engages with non-return means 47 in a funnel-shaped member 13 attached to the hull 14. The pieces of buoyant material may be distributed within the hull by periodically pumping water into the hull to effect turbulence therein. Alternatively, the pieces of buoyant material may be driven downwardly into the hull by compressed air instead of the plunger 22.

Abstract: 756,159. Antistatic fabrics. DUNLOP RUBBER CO., Ltd. June 22, 1954 [July 14, 1953; Oct. 20, 1953], Nos. 19444/53 and 28871/53. Class 37. An antistatic fabric is made up of fibrous material containing electrically-conductive carbon black and fibrous material free from such black in such proportions that the electrical resistance of the fabric as a whole is less than 100,000 megohms per unit square at all humidities. The proportion of black-containing fibrous material should not be less than 2 per cent of the whole and should preferably constitute 5 to 20 per cent. The fabric may be woven from a mixed yarn spun from the two fibrous materials together or the two types may be spun separately and woven, for example, to have a distinctive fine black-and-white chequered pattern. The fibrous material may be a regenerated cellulose such as a viscose rayon or nylon or polyester fibres spun from a melt containing carbon black may be used. The carbon black is preferably acetylene black [" Shawinigan " (Registered Trade Mark) black] or reinforcing furnace black or channel black may be used. Thus the fabric may, for example, contain 10 per cent by weight of viscose rayon containing 30 per cent of " Shawinigan " black, together with 90 per cent of black-free viscose rayon. The fabric thus obtained would have a resistance of between 0.5 and 5 megohms/unit square at any humidity. In place of black-free viscose rayon, cotton may be used.
