IPC: F28F9/22
Filed: 1943-08-27
Abstract: 568,937. Tubular heat-exchangers. WOODALL-DUCKHAM (1920), Ltd., and MILLENER, W. H. Aug. 27, 1943, No. 13974. [Class 64 (iii)] Tubular heat-exchange apparatus, e.g., a condenser, in which each of the fluids makes at least two parallel passes through the apparatus, comprises a cylindrical shell 10 permanently closed at one end and open at the other to receive a tube assembly incorporating at least two tube banks between inlet and outlet manifolds 13, 14 and a floating head 15, a pass plate formed of two relatively movable and separable parts 17, 17a, or 18, 18a, inserted between the tube banks and entirely unattached to the tube assembly, arcuate baffles 25 in space between the tubes and the shell at intervals along the length of the tubes, each arcuate baffle being connected at one end to a part of a pass plate and supported at the other adjacent to the edge of a pass plate, and means to press the two parts of the pass plate into contact with the shell when in the tube assembly, pass plate and arcuate baffles have been inserted, whilst maintaining a seal between the two parts . of the pass plate. In the form shown there are two pass plates or partitions composed in all of four flanged plates, 17, 17a, 18, 18a. The two plates of each pair are connected by bolts such as 19, 20 engaging in nuts such as 19a fixed to one plate of each pair. Tightening of the bolts, by the insertion of a tool through apertures in the casing when the tube assembly and partitions have been inserted, causes the pair of plates so drawn together to press the outer edges of the other pair of plates against the casing. Baffles 24 restrict the flow of fluid between the plates and the tubes. Openings 21 are provided in the plates for the passage of fluid from one side of each plate to the other. The bolts and nuts may be replaced by open L-shaped springs each attached at one end to :a baffle 24 and at the other pressing against the adjacent surface of another partition plate. In a double-pass apparatus, the single partition is composed of a large flanged plate which extends nearly across the casing, and a small auxiliary piece which closes the gap between the flanged end of the plate and the casing. The auxiliary piece may be of L-section and connected to the large plate by bolts engaging in nuts fixed to the flange. Alternatively, the outer edge of the auxiliary piece may be urged away from the large plate by a spring. Semi-annular baffles are attached to the large plate and its auxiliary piece.

Patent GB-887232-A (GB)
Title: Improvements in or relating to the transfer of electrostatic patterns
IPC: G03G15/30
Filed: 1958-05-06
Abstract: 887,232. Printing processes. KOLB, O. K. (Haloid Co.). May 6, 1958, No. 14443/58. Class 100(2) In a method of removing an image or pattern of particulate matter resulting from the development of an original electrostatic image electrostatically defined upon a retentive surface on to a transfer member adapted to be placed into and out of contact with said surface, the original electrostatic image is preserved for further cycles of development thereof and removal of the developed image. Distortion of the image at the zone of separation of said surface and said transfer member is avoided by applying an electrostatic field at the zone of separation by means of a conductive roller over which the transfer member passes for separation from the image-bearing surface. The roller may have a resilient cover (e.g. black rubber, sponge rubber, plastics, cloth, #-¢ inch thick) of 10<SP>4</SP>-10<SP>8</SP> ohm centimetres resistivity, to receive any foreign bodies between it and the transfer member without breaking smooth contact. The roller may move along the transfer member and imagebearing surface, or vice versa, and may be replaced by a rod or edge. The preferred voltage drop between the roller and the conductive backing of the image-bearing surface is 500- 900 volts. The image transfer may be effected by corona discharge at a position before the roller, but this step can be omitted with the preferred voltage drop, which itself effects the transfer. The low resistivity of the resilient cover prevents breakdown between the transfer member and the roller on separation thereof. Alternatively a grounded roller may be used, the conductive backing also being grounded. The apparatus illustrated is enclosed in a cabinet 90 to exclude light. The image is formed on the photo-conductive layer 56 (charged at 52) by optical projection at 53, developed at 55, and transferred at 56 to a paper web 77 (passing from a spool 78 to a spool 80) by a corona charging device 40. A conductive belt 43 passes over grounded rollers 41, 42 in contact with the web, which is separated from the layer 56 at the roller 42.
