Abstract: 813,621. Tanks. WHESSOE Ltd. Jan. 3, 1956 [Oct. 18, 1954], No. 29973/54. Class 69 (1). A vessel 2 in the form of a vertically disposed cylinder 7 with hemispherical ends (only the lower end 3 being shown in Fig. 1 which is a vertical radial section through the vessel wall at one of the points of support) is supported by a number of columns 1 around its circumference, each column being in rolling engagement with the underside of a bracket 4 secured to the outer wall of the vessel, and with a horizontal foundation at its lower end, so that it may rock in a vertical plane through the axis of the vessel to allow the vessel to expand and contract due to changes in temperature or pressure. The curved rolling surfaces at top and bottom of the column preferably have a radius equal to half the height of the column, and bolts passing through the base plates 8 of the brackets and tops 12 of the columns on the normal lines of contact retain these parts in contact while allowing the necessary play, blocks 15 and 16 on the base plates 8 also aiding in this respect. The columns may be of V, or inverted-V, form, engaging two adjacent brackets 4 and a single position on the foundation, or vice versa. The construction and arrangement of internal load supports shown in broken lines in the upper right-hand part of the Fig. is described in Specification 813,622.

Title: Knife holder for circular-knife cutting machines
IPC: B26D5/04
Filed: 1962-08-07
Abstract: 1,004,503. Fluid pressure apparatus. KARL RUD DIENES, FABRIKATIONGESELLSCHAFT FUR MASCHINENERSATZTELLE m.b.H. Aug. 7, 1962 [Aug. 9, 1961], No. 30270/62. Heading FIP. [Also in Division B4] The circular knife 4 of a cutting machine has its hub 3 connected to a piston 10 movable against the action of a spring 12 within a casing 35, which is itself connected by a rod 13 to another piston 14 movable against the action of a spring 18 in a casing 34, the arrangement being such that operating fluid entering the pressure chamber 16 of the casing 34 through a port 33 starts a lowering movement of the knife before a radial bore 20 comes into position to supply the fluid through an axial bore 15 in the rod 13 to the casing 35 and thereby effect a sideways setting movement of the knife. The spring 12 is stronger, by comparison with the corresponding piston area, than the spring 18 so that the knife will be lowered prior to being set to a position opposite a circular counter knife. The rod 13 is keyed against rotation in an angularly-adjustable cover plate 23 of the casing 34 and is adjustable in stroke by nuts 21. The knife 4 is held in place by adjustable spring washers 6 and the setting stroke is adjustable by a screwed stop 11.

Title: Method and apparatus for locally treating, e.g. heat sealing, a continuous web of material at locations which are spaced apart along the latter
IPC: B31B23/00
Filed: 1956-10-04
Abstract: 815,006. Seaming. MEULEN, L. VAN DER. Oct. 4, 1956 [Oct. 8, 1955], No. 30294/56. Class 42 (1). [Also in Group XVII] A machine for forming bags by heat sealing at intervals a longitudinally folded web comprises means to deliver the web at relatively high speed to a series of gripping and sealing means moving at a slower speed, the excess of web delivered forming loops between the gripping means, and means to accelerate the sealed web when released by the gripping means to its initial speed thereby taking up the loops. The arrangement gives additional time for cooling of the seams. A web of heat sealable material 2 is drawn from a roll 1 past folding and straightening means 6, 7 and is fed in doubled form to the combined sealing and gripping means. The latter consist of elongated bars 24, 16 carried respectively on a rotatable assembly 23 and a continuous belt 15, the speed of the bars 16, 24 being less than that of the web feed. The end belt carrying roller 22 has a series of slots which as each comes opposite a slot in a pressure air delivery pipe 27, directs an air blast against the web so that that portion of it immediately behind the last pair of bars 16, 24 to engage it, forms a loop 29<SP>1</SP>. This process may be assisted by the application of vacuum to the space between the bars 24 in which the loop is being formed via a pipe 46. As the next portion of the web is being gripped, the feed is momentarily decelerated by devices 14, 44 engaging the web. Each bar 24 comprises spaced heating elements 32 and a central rubber strip 35 and the bars 16 have heating elements 38 in spaced housings 36. Heat is applied for an initial portion only of the travel of the grippers, cooling taking place over the remainder. Needles 51 cooperate with the strips 35 to give lines of perforations between the bags, the bags being separated along these lines by web accelerating means 55, 58, 56, 57 operated at different speeds. Widths of bags may be varied by varying the initial web speed and thus the size of the loops, or by heating only selected grippers 16. 24.

Title: Improvements in method of and apparatus for rolling metal
IPC: B21B27/10
Filed: 1931-11-02
Abstract: 380,642. Rolling. CLARK, W. R., 225, Golden Hill Street, Bridgeport, Connecticut, U.S.A. Nov. 2, 1931, No. 30310. [Class 83 (iv).] The temperature of rolls 8 and of the sheet M before entering the rolls is thermostatically controlled by devices which automatically supply cooling or heating fluid as required, so as to avoid variations in the pass opening. If the temperature of the roll 8 rises it heats up the alcohol, ethyl ether, or alcohol and water, or other suitable fluid in the chamber 36 which expands the thermostatic bellows 26 and opens the valve 15 to admit cooling fluid from the pipe 17 to the chamber 12 one face of which is open to the roll surface. The fluid exits through the pipe 14. If the roll temperature falls, it operates another thermostatic bulb 58 to open valve 51 to admit cooling fluid through the chamber 49 to the roll surface. The bulb 36 is covered by a heat-insulating hood 38 while the bellows 26 operates the balanced valve 15 against an adjustable counterweight 29. The chambers 12 can be varied by having their ends and/or sides 19 adjustable to vary the area of roll exposed to the heating or cooling fluids. The temperature of the sheet M is controlled by a similar thermostatic bulb 14 to control the supply of heating or cooling fluid through valve 41 and nozzles 40 to the sheet. The nozzles 40 have individual valves adjusted by hand for localized heating required.
