Title: Improvements in or relating to bottle washing machines
IPC: B08B9/30
Filed: 1934-10-31
Abstract: 446,523. Endless - chain conveyers. DAWSON BROS., Ltd., DAWSON, G., and DAWSON, D. H., Ventnor Tank & Iron Works, Gomersal, near Leeds. Oct. 31, 1934, No. 31184. [Class 78 (i)] In bottle-washing machines of the kind in which the bottles are fed in rows intermittently through the machine by means of transverse carriers 2 supported by intermittently driven endless chains 3, the bottles are fed intermittently in rows from a conveyer 4 to the carriers of the machine by means comprising in combination an intermittently operated rotary member 8 adapted to turn each row of bottles received thereby through approximately a quarter turn so that the bottles lie on their sides, and a series of tipping arms 10 which is operated to raise and tilt each horizontal row from the rotary member and cause them to slide neck downwards into the cup-shaped openings 2x in the carrier presented to them. A pusher bar 5 removes the bottles from the conveyer 4 and pushes each one through one of a series of diverging channels on to the member 8. The channels effect the spacing apart of the bottles to correspond with the spacing of the cups 2x. The member 8 comprises a number of spider frames arranged in pairs to receive the bottles between them. An arm 10 is disposed between each pair of frames and is mounted on a rock-shaft 11. The pusher 5 is carried by a slidable frame 22 which is actuated through a pin-andslot connection 25 by the components 17, 18 of the linkage connecting the arm 16 on the shaft 11 to the rock-shaft 19. The lever 18 is fixed to the shaft 19, and its lower arm has a trigger piece 20 adapted to be engaged by the detent 15 on the reciprocating bar 14. The trigger is tripped to allow the parts to return to their normal positions. The member 8 is driven intermittently through step-up gearing 12 by one of the main sprockets 13 of the chain 3.

Title: Process of decomposing vegetable fibrous substances for the purpose of obtaining simultaneously the cellulose and the incrusting ingredients
IPC: D21C3/20
Filed: 1930-10-27
Abstract: Fibrous vegetable material is decomposed with aqueous alcohol containing 25-80 per cent alcohol, under pressure at temperatures above 150 DEG  C., whereby the cellulose and also the incrusting ingredients, including lignin and the sugar resulting from the decomposition, may be recovered.  Suitable alcohols are methyl, ethyl, and their homologues, and polyvalent alcohols such as glycerine.  In an example, wood chips with 10 times their weight of 50 per cent alcohol are heated for 3 hours at 150-180 DEG  C., the temperature is then raised to a maximum of 210 DEG  C. for a further 3 hours, the alcohol being renewed several times.  Raw cellulose is obtained, and by evaporating off the alcohol, lignin and other substances are recovered.  The rate of decomposition is accelerated by the addition of small quantities, e.g. up to ,1 per cent, of acid or basic substances.  Examples of suitable acid substances are hydrochloric, sulphuric, formic or acetic acids, sodium bisulphite or bisulphate; examples of suitable basic substances are oxides and hydroxides of alkaline earths, and sodium or magnesium carbonate.ALSO:Fibrous vegetable material is decomposed with aqueous alcohol containing 25-80 per cent alcohol, under pressure at temperatures above 150 DEG  C., whereby the cellulose and also the incrusting ingredients, including lignin and the sugar resulting from the decomposition, may be recovered.

Title: Improvements in furnaces
IPC: F23H13/06
Filed: 1952-12-23
Abstract: 733,374. Furnaces. BIGELOW-LIPTAK CORPORATION. Dec. 23,1952 [Jan. 15, 1952], No. 32562/52. Class 51 (1). A refuse-consuming, e.g. bagasse, furnace comprises a hearth or cell with a side wall, a door in the wall, a sill in the cell adjacent the door, a movable floor in the cell and means for upwardly moving the floor so that material thereon will slide downwardly on to the sill. As shown the invention is applied to a furnace of the type shown and described in Specification 733,373, each perforated cell floor 19 being tiltable in an upwardly direction by the action of floor lifting means. Each floor 19 comprises four in number flanged castings 25, 27, 29, 31 bolted together along their inner flanged edges at points where pads 37 have been cast on. Each casting is perforated at 59 and is provided on its underside with suitable reinforcing ribs the main one of which 39 carries a part of a horizontal flange 41 the whole of which serves as a convenient attachment for the floor-lifting means. These means comprise a pressure fluid operated cylinder 47 suitable pivot means being provided to attach the cylinder to the floor of the pit 55 beneath the cell and to attach the piston rod to the flange 41. In operation each floor 19 is caused to swing upwards about connections 69 pivotally attaching the floor to the edge of the pit thereby dumping ash or other material on the floor on to a sill 23 located to the rear of doors 21 through which the ash &c. is ultimately removed. During the upward movement each floor will scrape its respective cell wall to remove slag and other clinging materials. Each sill 23 has a projecting lip 75 that remains close to the surface of its respective floor when the latter is tilted to prevent material from sliding into the pit 55.

Title: Improvements in or relating to a tape winding machine
IPC: B65H54/68
Filed: 1947-12-10
Abstract: 654,171. Winding tape on cards, CREED B. C. Dec. 10, 1947, No. 32569. Convention date, Dec. 12, 1946. [Class 42 (ii)] A machine for winding tape on cards includes a rotatable control cam, a rotatable locking cam, a clutch located between a driving means and the cams and means for effecting the simultaneous disengagement of the clutch and engagement of a locking member with the locking cam. The card holder 12 may be U-shaped with a cross-bar 13 having equal, slight, opposed transverse bends immediately adjacent side arms 15 and supporting shaft 14. Shaft 14 is maintained in driving connection with an intermediate shaft 52 by gears 19, 51. Intermediate shaft 52 also drives, through change gears 40 a cam-shaft 33 carrying a stepped cam 36 for giving intermittent motion to the tape guide 23 secured adjustably to a slidable shaft 20, to which a cam finger 24 is also fixed. The cam finger 24 has a spring- pressed plunger 30 which is held against the cam 36 and as the cam rotates is urged into successive steps 37 of the cam and finally into an annular groove 38. The number of steps 37 of the cam 36 determines the number of rows of tape which will be wound on a card and the gear ratio between holder shaft 14 and cam-shaft 33 determines the number of throws of tape which will be wound on each row and on the complete card. When the card is completed, the cam-shaft 33 will have made one revolution and a trip cam 87, also on shaft 33, will open the circuit of a relay switch to simultaneously de-activate two solenoids 66 (not shown), 76. The solenoid 66 thereupon declutches a driving shaft from the drive of an electric motor. Simultaneously, solenoid 76 permits a locking tooth on a locking lever 77 to rise into contact with a locking tooth on a cam 82 on the intermediate shaft 52. Shaft 52 is normally driven from shaft 47 in belt-driving engagement with the clutchcarrying driving shaft. To start the machine, downward pressure is applied to a handle 90 which is arranged to activate the solenoids 66, 76 and release the locking tooth on the cam 82. The tape guide 23 includes a tape tensioning device.
