Title: Improvements in sheet-delivery apparatus
IPC: B65H31/00
Filed: 1930-07-08
Abstract: 358,559. Sheet-delivery apparatus. BARKER, R. W., 56, Ludgate Hill, London. -(American Bank Note Co. ; 70, Broad Street, New York, U.S.A.) July 8, 1930, No. 20675. [Class 100 (i).] Apparatus for delivering printed sheets from a machine in which they have been wound up with a web of paraffined paper, as described in Specification 357,307, comprises an inclined shelf 31 slidably carried by a base-frame 23, 24, 25, Fig. 6, mounted on a hydraulic or other ram 13, Fig. 2, for raising and lowering the shelf with respect to delivery tapes 11, lever devices operated by the movements of the ram 13 being provided to cause the shelf 31 to slide along the frame so that the sheets strike an inclined tailboard 48 at approximately a constant distance from the tapes as the shelf is lowered. The shelf 31 has straps 32 .. 35 on its underside slidable on transverse bars of a carriage 30 so that it can be adjusted transversely of the line of the delivery of the sheets by means of a hand-wheel 38 operating through spindles 37, 40 on the carriage 30, the spindle 40 having pinions 43, 44 engaging racks 45, 46 on the shelf 31. The carriage 30 is slidable in the direction of the sheet delivery on the side-bars 23, 24 of the base-frame 23, 24, 25 which are connected by a cross-plate 14. Journalled in bearings 19 on the undersurface of the plate 14 is a shaft 20 operated by a hand-wheel 21 and carrying a worm engaging a segmental worm wheel 18 fixed to lugs 17 on the top of the ram 13. The plate 14 is pivoted on a pin 16 fixed to the lugs 17 and by turning the hand-wheel 21, the slope of the plate 14 and therefore of the shelf 31 can be adjusted relatively to the tapes 11. A stop 22 on the ram 13 limits the movement of the plate 14. Lugs 59 fixed to the carriage 30 are pivoted to a link 56 having a pin-and-slot connection 57 with a lever 55 pivoted to a bracket 54 fixed to a slide 52 movable in a slideway 53 formed on the exterior of the hydraulic cylinder 12. The slide 52 is connected by a link 62 with the pin 16. A camsurface 61 on the lever 55 bears against a roller 60 fixed to the cylinder 12 and is so designed that if the ram 13 is raised or lowered or the plate 14 rotated about the pin 16 the carriage 30 is moved relatively away from or towards the tapes 11 so that the distance between the discharge point of the tapes 11 and the part of the board 48 struck by a sheet being delivered is maintained approximately constant. The board 48 may be adjusted manually along a slot 47, Fig. 5, in the shelf 31 according to the size of the sheets. A side gauge 49 may be provided having tongues adapted to fit into pairs of holes 50, 51 on the shelf, the wheel 38 providing a fine adjustment. Hydraulic power is applied to the cylinder 12 from pipes 63, 65.

Title: Improvements in looms and methods of weaving
IPC: D03D47/40
Filed: 1959-06-16
Abstract: 918,776. Shuttleless looms; forming selvedges. SULZER FRERES S.A. June 16, 1959 [June 27, 1958], No. 20675/59. Classes 142 (2) and 142 (4). In a loom weaving two fabrics 19, 21 side by side with a common weft 18, the weft at each selvedge is sometimes cut close to the edge of the fabric and sometimes cut away from the edge and tucked in. The gap between the fabrics is such that when the weft is cut at the edge of one fabric, it is the correct length for tucking into the other fabric. Two pairs of shears a, b, operating in any desired sequence, are provided at the input and output sides of the loom; or the output side may have shears at position a only, the correct length for tucking in being obtained by drawing back the weft after insertion. There may be two pairs of shears between the fabrics, or one pair may be shogged from position c to position d. The edge warp threads may be closed or partly crossed early, or may be leno woven as described in Specification 657,421, to prevent the cut ends of weft from springing back into the shed.

Title: Improvements in and relating to apparatus comprising relatively oscillatory members
IPC: B25D9/08
Filed: 1959-06-17
Abstract: 927,903. Percussive tools. C. LEAVELL. June 17, 1959 [June 18, 1958], No. 20870/59. Class 124. Apparatus for maintaining a predetermined relation between two oscillatory elements comprises a connecting linkage means to transmit force between a first and a second oscillatory element, means for automatically adjusting the force, and means for maintaining any adjusted value relatively constant throughout any cycle of the oscillatory motion of the elements. As shown, applied to a pneumatic percussive tool, the first element comprises a casing 356 forming a cylinder and attached to the casing of a percussive tool and the second element comprises a piston 320 which may oscillate in the cylinder, the upper part of the cylinder being connected to the lower space of the tool cylinder and the lower part of the cylinder to the upper space of the tool cylinder, and the effective area of the piston being equivalent to the areas of the ends of the tool cylinder. One piston-rod 353b on the piston 320 extends outside the lower end of the cylinder and a second piston-rod extends upwardly of the cylinder into a second cylinder 374 and is provided with a piston 352. The cylinder 374 carries a chamber 368 supplied with compressed air through a nozzle and is provided with vents 334b1 connected to a chamber 334b2 connected in turn to atmosphere through non- return valves 334b3. If, during oscillation of the piston, it rises against the pressure in the chamber 368, the chamber 356a is vented to atmosphere and the piston 320 moves downwardly in its cylinder. Similarly if the piston moves too far downwardly in its cylinder the chamber 368 is vented and the piston rises. The piston is thus maintained in a relatively constant position during its oscillatory movement. In a modification, Figs. 3 and 4 (not shown), two cylinder and piston assemblies are provided, one on either side of the tool casing. Specification 927,902 is referred to.

A shaft 24 is driven from the axle 15 by the clutch and chain and spur gearing shown. Fixed on the shaft 24 is a split block 25, Fig. 5, carrying the pivoted hammers, which strike the end of the shank 11 as the shaft 24 rotates. The hammers are raised by the engagement of projections 29 with flat surfaces on the block 25. The hammer heads are fitted with removable cones 28 of hardened metal. The share is retracted between the blows by a spring and the forward movement of the plough. The Specification as open to inspection under Sect. 91 (3) (a) states that the invention may be applied to multiple-share ploughs, and that the shaft 24 may be driven from a tractor. This subject-matter does not appear in the Specification as accepted.

Abstract: 1430541 Demagnetization PRZEMYSLOWY INSTYTUT AUTOMATYKI I POMIAROW MERA-PIAP 13 May 1974 [16 May 1973] 21002/74 Heading H1P Demagnetizing large ferromagnetic components of electromagnetic chucks is effected by energizing the excitation winding from a phasecontrolled A.C. fed bilateral semi-conductor rectifier 2 with alternating pulses of sequentially opposed senses and amplitudes progressively decreasing to zero. Switch 4 has contacts S 1  and S 2  and is operated to disconnect the chuck from continuous operation and initially a transformation circuit 3 comprising a capacitor is energized over S 2  from a constant voltage source U z . Thereafter S 1  closes to initiate a timing and logic circuit 5 fed from circuit 3 periodically reversing the output voltage U WY , and S 2  opens to deenergize circuit 3, whose output then progressively decays to reduce the conduction angle of rectifier 2 and the amplitudes of successive pulses of opposed polarities at its output; separated by time intervals for collapse of magnetic flux in the chuck, thus resulting in progressive demagnetization. The rectifier may alternatively be set for continuous energization of the chuck at a selected polarity.

Filed: 1924-09-05
Abstract: 236,884. Soc. Anon. le Carbone. July 12, 1924, [Convention date]. Arrangement; carbon electrodes, making; electrodes; gas batteries.-A tubular carbon electrode a, open at both ends is immersed so that electrolyte has access to both inner and outer faces, which are previously treated to render them impervious to liquids whilst remaining permeable to gases. Suitable treatment consists in plunging the electrode into a solution of paraffin in benzene, and then evaporating the solvent, or in subjecting the electrode to prolonged immersion in an atmosphere highly charged with heavy hydrocarbons, such as that in the flues of a tar-distilling furnace. The lower end of the electrode may have perforations g. A zinc electrode d surrounds the electrode a, the electrolyte used being a solution of ammonium chloride. The hydrogen liberated is stated to pass to the interior of the electrode a and rise to the surface, no oxidation of hydrogen within the electrode body taking place. Ammonium liberated is retained in the electrode body. Preferably, a central rod b of carbon, which may be treated in the above way, is disposed within and electrically connected to the electrode a. The rod b and electrode a constitute elements of a gas battery, the action of which is explained as aiding the escape of hydrogen.

Title: Improvements relating to the preparation of calcium carbonate
Inventor: FORBAT GEORGE
IPC: C09C1/02
Filed: 1955-07-21
Abstract: A powder containing over 97 per cent of calcium carbonate, together with magnesium carbonate, suitable for use as a filler for paints, plastics or rubber is obtained by cleaning, substantially drying and pulverizing egg-shells.  In an example the egg-shells are passed from a hopper into a horizontal steam-heated worm conveyer in which they are treated with caustic soda to remove proteinaceous materials and the mixture is then discharged into a centrifuge to separate the egg-shells.  The caustic soda is recycled and the egg-shells are washed with hot water in a further horizontal worm conveyer and passed to a second centrifuge where the water is separated.  They are then passed to a feed hopper for a mill in which they are crushed. In an alternative procedure the shells are placed in hot water containing bleaching and deodorizing agents in a washing machine having a pulsator or agitator.  They are removed, centrifuged and tumbled in a hot air drier at 230 DEG  F. whereby they are also broken up, and finally milled to e.g. 120 mesh (British standard). The product is also said to be useful for cosmetic, pharmaceutical, medical and horticultural purposes.ALSO:Calcium carbonate obtained from egg-shells by cleaning, drying and pulverising is stated to be useful for water softening.

Title: Gas holders
IPC: F17B1/12
Filed: 1925-08-24
Abstract: 248,261. Williams, A. H. T. Aug. 24, 1925. Holders.-The capacity of gas holders is increased by providing a chamber inside the inner lifs for containing gas at a relatively high pressure. Figs. 1 and 2 show a holder having a tank formed by a foundation 10 sunk into the ground and walls 11. The high pressure chamber is formed by a bottom 22, side wall 23, and a crown 24. The crown 24 is provided with supports 27 carried by brace-members 25 and posts 26. A highpressure gas pipe 43 and a low-pressure gas pipe 37 extend transversely beneath the bottom of the gas holder. The pipe 43 has a stand pipe 44 opening into the highpressure chamber and terminates at a valve 40. The pipe 37 leads from the valve 40 and has a stand pipe 38 projecting into the outer gas holder. A valve 45 controlling the supply of high-pressure gas to the pipe 43 and a valve 39 for controlling the supply of low-pressure gas to the mains are arranged in a pit or box having a cover 47. The valve 40 is arranged in a shaft 30 and is operated when it is desired to renew the gas in the outer bolder by means of a hand-wheel 42. The shaft .30 leads to a tunnel 32 which allows access to be had to the high pressure chamber through a manhole cover 33. Water finding its way into the high-pressure chamber is collected in a basin 34 and may be drawn off by means of a pump 36. The crown 21 of the inner lift is supported when pressure is removed from the outer holder by cross-members 29 and posts 28 on the crown 24. In another construction the entire tank is above the ground level, the provision of the pump 36 being thereby rendered unnecessary.
