Title: Process fluid heater
IPC: B01J8/06
Filed: 1966-04-28
Abstract: 1,129,076. Fluid heaters. FOSTER WHEELER CORP. 28 April, 1966 [11 June, 1965], No. 18729/66. Headings F4A and F4S. A process fluid heater has rows of vertical tubes 41 extending through an enclosure 21 into which burners 31 fire, the gases from the enclosure 21 then passing over convection heated tubes 27. The tubes 41 are supported by a weight and pulley arrangement 49 from frame 53, and are supplied with fluid from upper header 50 through connectors 58, 60. The tubes 41 are provided with removable end caps 47, through which catalyst (54, Fig. 5) and catalyst support cones (51) may be inserted. From the tubes 41, the fluid passes through connectors 55 to a horizontally extending lower collector header 42, which is mounted in a support casting 44 by a bracket and slot arrangement (48, 46, Fig. 2) to permit longitudinal expansion of the header. A metal bar 61, having expansion rate similar to that of the header 42 is placed parallel thereto in contact with and between the tubes 41, a little above the point of connection of the connectors 55 to the tubes. This expands as the header does, thereby bowing out the tubes 41 at their lower end, and preventing the connectors 55 from breaking. The bar is formed from a plurality of half sections 63, Fig. 3, each section engaging four of the tubes, the sections being bolted together at their edges. The sections associated with each row of tubes, are cross linked by members 73, to form the bar 61 which is maintained in place by spaced lugs (77, Fig. 2) on the tubes. In a modification (Figs. 5 to 8) provided with a single row of vertical tubes, the bar (61) is formed from two overlapping half bar sections (81).

Title: Process for bonding and covering flexible materials
IPC: D06M15/55
Filed: 1971-06-03
Abstract: 1310631 Laminates BAYER AG 3 June 1971 [3 June 1970] 18788/71 Heading B5N [Also in Division C3] A process for covering a flexible material comprises providing the material by a direct or reversal process, with a coating which has been produced from a solution comprising a hydroxyl polyurethane and an epoxide resin both dissolved in an organic solvent. In the reversal process, the solution is applied to a support and dried, the dried layer united with the flexible material which may itself be applied as a coating and the support removed. In a modification of the process, the solution is applied to the flexible material to form a coating thereon and is bonded to another material by pressure either before the coating has completely dried or after heat-tackifying the coating. The polyurethane is preferably linear and may be made by reacting an aromatic, aliphatic or cycloaliphatic diisocyanate with a slight excess of a linear hydroxyl polyester obtained from a dicarboxylic acid and a diol. The epoxide resin may be obtained by reacting 2,2-bis-(4-hydroxy-phenyl)propane and epichlorohydrin. The solvent may be a ketone, an aromatic hydrocarbon, a chlorinated hydrocarbon or a mixture thereof. The solution may also contain a polyisocyanate, a natural or synthetic resin or a substituted carbodiimide and may be applied by brushing, doctoring or rolling. More than one layer of the solution may be applied. The flexible material may be a textile, leather, artificial leather, synthetic plastics or metal as may the other material to be bonded thereto. In the example, aluminium foils are coated and overlaid under pressure with foils of polyethylene, polypropylene or a polyester; woven linen fabrics are coated, assembled with the coatings on contact and pressed.

Title: Data compression system
Filed: 1975-07-24
Abstract: 1515851 Data transmission J S HOERNING 24 July 1975 [30 April 1974] 18903/74 Heading H4P In a data transmission system including, for example, a terminal A connected to a computer I over a transmission line E associated with modems D, F, the terminal A and computer I generate and operate upon characters expressed as a constant number of bits, e.g. 8 bits, but these characters are encoded at the transmitting end by means of a compaction device generating a bit stream in which varying numbers of bits are used to express different characters, whereby the overall length in bits of the original data stream is shortened, making for more efficient use of the transmission medium. The compaction device at the receiving end operates to decode the transmitted data which is thus restored to its original form. In a preferred embodiment combinations one to eight bits in length are used, and the compaction device produces these by the controlled switching of logic devices, e.g. a diode matrix constituting a read-only memory, associated with a read-write or buffer memory, e.g. a magnetic core memory, in which the data is stored prior to compaction in the "transmit" mode or after decoding in the "receive" mode.

Abstract: 835,381. Control of several D.C. motors. COMPTOIR DE L'INDUSTRIE COTONNIERE ETABLISSEMENTS BOUSSAC. June 17, 1958 [June 19, 1957], No. 19297/58. Class 38 (3). Electric motors M1-M3 are supplied from a generator G1 and are adapted to drive successive sections through which strip material undergoing treatment moves longitudinally, a winder for the material being driven by a motor M4 which is supplied from generator G2. The speed of operation of the plant as a whole is determined by the voltage supplied from valve apparatus 21 to the field windings 8, 10, of the generators G1, G2, the plant being started by closure of switch 22 and accelerated by switch 23 up to a speed set by hand wheel 25. Motors M1, M2 have balanced series field windings 2, 4 and the tension in the material between these motors is adjusted by means of resistor 15 in bridge circuit 15, 16. The tensions in the material between motors M2, M3 and M3, M4 -are dependent upon the power developed by motor M4 which is adjusted by rheostat 27 in series with the field winding 9 of generator G2. During operation, the machine M3 is driven as a generator having its field winding 5 controlled by rheostat 19. As the diameter of the material on the reel increases, the current passing through series field winding 11 of the generator G2 tends to increase, but since this field winding opposes the windings 9, 10, the total excitation of the generator is held at a value such that the tension of the material being wound is maintained at a constant value. The tension of the material during standstill is fixed by including resistors 30, 31 in series with field windings 6, 9. The material is removed from the reel by reversing the motor M4 through switch 13a, the excitation of generator G2 being reduced by connecting resistor 30 in series with field winding 9. Operation at low speed for starting is provided by reducing the output voltage of the source 21, and by inserting resistor 26 in circuit with the field windings 6, 9.

Title: Improved process of dehydrating castor oil
IPC: C09F5/06
Filed: 1950-08-02
Abstract: In the catalytic dehydration of castor oil with diluted sulphuric acid as the catalyst, the acid is added in the form of a preformed emulsion in a fatty oil, such as in castor oil itself. Sulphuric acid of 80 per cent strength at the most and preferably from 60 to 70 per cent is used.  The acid emulsion is preferably added gradually in the course of the process to the castor oil, which is at reaction temperature.  A batch or continuous process may be used, in the latter the catalyst being added at various stages of the reaction. The reaction temperatures preferably range from 240 DEG C to 250 DEG C, and normal or preferably reduced pressure may be used.  The dehydrated castor oil may be subsequently bodied by further heating, or the bodying may be effected simultaneously with the dehydration by using a higher reaction temperature, such as 280 DEG C.  The process results in a saving of sulphuric acid with less risk of discolouration and polymerization.
