Title: Improvements in or relating to devices for applying closures to bottles or the like
IPC: B67B3/10
Filed: 1953-04-21
Abstract: 725,858. Capsuling bottles &c. HALL, G. H. April 21, 1953, No. 10941/53. Class 125 (2). For applying foil capsules to bottles &c. an integral or one piece body 11 is lowered to cause the bottle neck to enter a recess 12 in which a flat resilient disc 14 rests in a groove 13. The bottle causes the disc 14 to pivot and distort about the upper edge 15 of the groove 13 so as to wipe the capsule about the bottle neck. The disc is restored to horizontal position by a spring-loaded plate 16 and vents 18, 19 are provided in the disc and the holder respectively. The device may be fitted to a capping machine.

Title: Improvements in boiler feed water apparatus
IPC: F22D5/08
Filed: 1920-04-20
Abstract: 157,024. Davin, W. W. April 20, 1920. Feed-water, supplying and controlling.-In a gravity-feed apparatus, comprising a closed chamber with connections to the steam and water spaces of a boiler, the feed-water is discharged bv the automatic admission of boiler steam to the surface of the feed-water. The feed inlet valve 33 in lifting automatically opens a restricted vent valve 36 and permits the flow of water into the tank. The boiler pressure in the delivery pipe 23 acts on top of valve 26 retaining it closecl and the restricted vent valve 30 open. The compression of air in tank 1 due to inflow of feed-water lifts the steam valve 12, but to ensure a positive action of this valve a float 21 mav be fitted. The steam valve 12 in rising places the pipe 10 from the steam-dome of the boiler in direct communication with the interior of the tank through ports in valve 12. The pressure in tank 1 now equals the boiler pressure, and the valve 33. together with the vent valve 36, closes. The valve 26 is subjected to a difference of pressure equivalent to the head of water in the tank, on its underside. In lifting, it closes the vent valve 30, and the contents of the tank down to the level of the pipe 23 are discharged to the boiler. The steam valve 12 now falls and the action is repeated. The steam valve 12 may be operated by hand to regulate the feeding of the boiler. If desired to feed the boiler at shorter intervals with a smaller quantity of water, the valves 4, 6 are closed. The effect of the entering water is to increase the air pressure in the tank more rapidly and raise the steam valve 12 at shorter intervals, a smaller quantity of water being discharged each time. The pipe 3 may also be used for the supply of condensing-water to the spray head 37, in which case it is connected to the water supply. Water is sprayed into the tank each time the valve 33 lifts and condenses the steam left over after each discharge. The speed of discharge is regulated by the valve 40. A counter gear may be operated by the valve stem 27 to indicate the number of discharges from the tank.

Abstract: 750,606. Mobile collapsible jib cranes. BRITISH HOIST & CRANE CO., Ltd., and EVANS, P. N. May 1, 1953 [May 1, 1952], No. 11020/52. Class 78 (4). A bogey can be fitted to a slewing jib crane which dismantles for transport and which, when erected, is roughly balanced on the bogey so that it can be moved along a track. In the form illustrated road wheels secured to axles 17, Fig. 1, on the chassis of the crane may be replaced by bogies 22 running on a rail track 21. The bogies include plates 23, Fig. 2, formed with slots 24 into which extend the reduced ends 18 of the axles 17 to permit the crane to move over a curved track. The crane is generally similar to that described in Specification 722,703 and may be modified in accordance with Specification 750,608 both of which Specifications are referred to. The axles 17 are disposed adjacent to the centre of gravity of the crane but slightly displaced towards the mast 13, and the crane is steadied during movement along the track by securing the road wheels 15, 16 to arms at the front and rear of the chassis similar to those provided on the jib in Specification 750,607 which is also referred to. The crane is supported on jacks 19 during use. According to the Provisional Specification only, the crane may be roughly balanced about the axles 17 both when erected and when dismantled, or separate axles for the rail bogeys and the road wheels may be provided near the centres of gravity of the crane in these two conditions.

Abstract: 430,378. Piles or columns for foundations. BRITISH STEEL PILING CO., Ltd., POUND, E. C., and HILEY, A., Thames House, Millbank, London. April 12, 1934, No. 11093. [Class 68 (ii)] A sectional concrete hollow pile or like cylindrical unit comprises sections held together by longitudinal tie rods, keeping them in compression, in which state the pile &c. is driven. Fig. 1 shows a completed pile comprising precast tubular units 2 ; the central bores 3 have slightly flared ends 5 in which are fitted short tubular positioning-sleeves 15. The shoe 6 is also flared, and is made with a shoulder 8 and with lugs 10 slotted to receive tubular tie rods 12. The units 2 are jointed by the positioning-sleeves 15, by a mixture of rubber latex and cement in the annulus between the sleeves 15 and the ends of the units 2, and by a sealing-band 18, which may consist of a strip of adhesive tape wrapped tightly round the joint. The ends of each section are strengthened by steel bands 25. After driving a suitable number of sections in succession to form a pile, the aperture above is excavated, and stones 27 and concrete 26 are placed in it to form a seal, and is tamped; if water is pre. sent the materials may be lowered in containers, e.g. short cylinders of perforated zinc. The bore is then de-watered, and a cage of steel reinforcements i s lowered into it. The bore is then filled with concrete, which is allowed to set. The tie rods 12 are then withdrawn, and while being withdrawn are used for supplying grout under pressure for forming a coating round the pile and for permeating and consolidating the soil. The tie members 12 may be placed in passages in the walls ; they may be left in place, and may be supplemented by the ropes. When the pile is driven through soft ground to a harder stratum, the shoe 6 may be plugged with a weakly-cemented block of sand &c., which afterwards can be removed. The interior surfaces of the units 2 may be protected by a sheeting or coating, which may be removed.

A newspaper vending machine comprises a series of horizontal shelves 1 supporting the lower edges of newspapers P disposed in upright planes, and a lever arm 11 connected to each shelf. The lever arms rest on a series of supports 2 which are advanced step by step so that the last 2F of the series successively moves to leave each lever arm in turn unsupported to allow the corresponding shelf to tilt and the newspaper resting on it to fall into a delivery tray. The supports are mounted on an endless chain 20 which carries a second series of supports separated from the first series by a gap which permits one shelf to tilt before the second series raises it to the horizontal. The supports are advanced by a ratchet dog 3 moved by an external handle (45, Fig. 1, not shown) connected to a rod 31. Movement of the rod is blocked by a peg (64, Fig. 4, not shown) on a wheel (63) rotated by a coin wheel (6). The last newspaper to be released is contatted by a spring-biased feeler (5, Fig. 4, not shown), which allows a pin to block the passage of the coin (C) to the coin wheel, arid divert the coin, when the last newspaper has been dispensed.
