Patent GB-2303098-A (GB)
Title: Food moulding apparatus and method of forming food products
Inventor: LONDON EUGENE J
IPC: A23P1/10
Filed: 1996-07-03
Abstract: The invention provides a molding apparatus and process of molding formable materials which comprises at least one supply manifold (44) for receiving a formable material and plungers or pistons (52) for applying pressure to the formable material within the manifolds. A mold plate (24) including at least one mold cavity 26 is driven by drive means 28 between fill and discharge positions, with the at least one mold cavity 26 selectively exposed to manifold 44 when in the fill position. A clamp member (110) is positioned adjacent the mold plate 24 when in the fill position, and pressure is applied on member 110 to clamp plate 24 against manifold 44. Member 110 and associated structure apply pressure to the clamp member compensating for deflection of these structural members which maintains plate 24 in firm clamping relation relative to manifold 44. The clamp plate therefore does not operate in flexure, and eliminates the need to provide the clamp plate with a thick cross section or heavy mass which would accommodate forces normally encountered during filling of the mold cavities. In this manner a mold plate having a relatively thin section, and a clamp member also of relatively thin section may be utilized, to allow a machine having significantly increased width to be realized. The significantly increased width of the machine will correspondingly increase capacity, and also allows compatibility with other processing equipment. A knock-out mechanism 60 removes formable material from cavity 26 when plate 24 is in the discharge position. An alternative supply is depicted in figure 11 (not shown).

This combination can even include a device that contains all radial holes, Fig.2 or all radial tubes (Fig.3). The distance that the gas is injected into the air stream is small at the radial holes (15) and larger at the radial tubes (17).
Patent GB-965604-A (GB)
Abstract: 965,604. Bending tubes. BABCOCK & WILCOX Ltd. July 16, 1962 [July 17, 1961], No. 27191/62. Heading B3E. A method of bending a tube by means of a bending roller comprises passing the tube through a heating region disposed at the inside of the projected bend close to a bending zone to heat the tube metal at the inside of the bend to high temperature relative to that at the outside of the projected bend at which high temperature the tube metal is readily deformable, passing the tube transversely of the axis of and in contact with the roller to effect bending thereof at the bending zone and passing the bent part of the tube immediately after bending through a cooling region disposed at the inside of the bend close to the bending zone to cool the heated part of the tube to a temperature at which it is no longer readily deformable. In one embodiment, Fig. 1, a tube 4 to be bent is fed over a mandrel 5 by rollers 6 to a circumferentially grooved offset bending roll 1 and is heated, e.g. to a temperature of 1200‹ C., in the portion to form the inside of the bend by a gas burner 7. As the tube is bent by engagement with the roll 1 cooling means 8, separated by a refractory screen 9 from the heater 7, discharge cooling fluid, e.g. carbon dioxide, nitrogen or inert gas suitably humidified on to the hot inner part of the bend. The tube is then guided by a plate 12 into engagement with a second roller 11 which exerts additional bending stress. The mandrel 5 may be formed with a burner nozzle 17, supplied with gas through a bore 18 in the former, to heat the inside of the tube bend within the tube. Alternatively or in addition the mandrel 5 may have coolant discharge means for cooling the inside of the tube opposite the cooling means 8. The bent tube may be subsequently heat treated. In another embodiment, Fig. 4, a tube 21 clamped at 30 to a peripherally grooved former 20 rotated by a shaft 23 is guided to the former 20 by a sleeve 22, is heated by a burner 28, bent around the former 20 as it rotates, and cooled by means 27, separated from the burner 28 by a screen 26. Additional heating and/or cooling means may be disposed within the tube.
