Abstract: 1,065,329. Air conditioning units. LUWA A.G. Dec. 13, 1963 [Dec. 14, 1962], No. 49304/63. Heading F4V. In an induction air-conditioning unit any water separating out from the secondary air stream on passing through a heat exchanger is withdrawn by a jet pump arrangement using branched primary air as propellant. As illustrated, primary air supplied through a pipe 3a passes through a filter 7, heat exchanger 5 and nozzles 8 thus drawing secondary air through a filter 7<SP>1</SP> and heat exchanger 6. A partition 2 separates the primary and secondary air streams and serves to collect condensate from the heat exchanger 6 which is withdrawn through a pipe 16 by a jet pump 12 whose propellant pipe 15 is fed from the primary air stream. The pipe 15 also serves to withdraw condensate formed by the heat exchanger 5. In a modification, not shown, condensate is collected in separate. containers in the unit to which the pipes 15 and 16 are connected. Suitable control means may be included to automatically close the propellant pipe when no condensate is formed, particularly when the unit is used to heat air.

[Also in Division F2] A seaming device comprises a paramagnetic mandrel M about which material is formed for seaming and magnet means 26 to position the mandrel in a required position, the arrangement being such that in the operation of the device material is fed continuously along the mandrel for continuous seaming thereof and the mandrel M is positioned by the means 26 continuously during the seaming. In apparatus for forming a tube, a planar laminated web W, Fig. 1, comprising a metal foil layer sandwiched between two heat sealable plastics layers, is guided into tubular form about the mandrel M by a concave roller set 12 and a belt 16 trained about idler rollers 18. The mandrel M is supported for limiting floating movement by a cantilever-like mounting 24 comprising a fixed L-shaped bracket 42 the forward leg of which terminates in a fork (46), Fig. 6 (not shown), to embrace a reduced neck 48 of the mandrel M. A saddle block 50, Figs. 1 and 5, loosely overfits a screw 54 secured to the forward leg of the bracket 42 and which is adjustable by a screw and nut arrangement 56, 58 to alter the position of the block 50. The block 50 is formed with bifurcated legs 60 to embrace the neck 48 which is provided with a pin 62 retained by screws 64 to provide limited rotational movement of the mandrel M to permit precise formation of the longitudinal seam by the application of non-uniform pressure transversely of the seam with lesser pressure adjacent the underlapped side edge to cause flow of softened thermoplastic material theretoward. The overlapping longitudinal margins of the web W pass beneath a heating assembly 20 and are firmly held between belts 28, 38, Figs. 1 and 9, the tape 28, which is preferably made of fibreglass coated with polytetrafluoroethylene, running along slots in the mandrel M. Heat is applied to the seam by electrical heating elements 92, 84 in the assembly 20 and the mandrel M, respectively. The element 84 is maintained at a lower temperature than the element 92 and is supported in the mandrel M by a stainless steel spacer 88 and a beryllium spacer 90. A hairpin-like cooling conduit 96 is provided in grooves 94 in the mandrel and contacts the mandrel downstream of the assembly 20 only. After heating, the partially molten joint passes beneath a cooling shoe 22 having a cooling conduit 82, Figs. 1 and 8, passing therethrough. The magnet means 26 co-operates with the shoe 22 and comprises electromagnet cores 74 terminating in polepieces 76, 78 and provided with windings 80. Supply of current to the windings 80 during seaming causes the polepieces 76, 78 to attract the metallic mandrel upwardly and apply pressure to the cooling joint. Air is supplied to an axial bore 100, Fig. 9, in the mandrel M having radial passages 104 to properly size or control the internal diameter of the tube being formed. A second magnet means, similar to the means 26, may be provided at the heating assembly 20.
