Title: Heat exchangers
IPC: F28D7/16
Filed: 1946-10-02
Abstract: 631,115. Tubular heat-exchangers. TRIGGS. W. W. (Air Preheater Corporation). October 2, 1946, No. 29400. [Class 64(iii)] A heat-exchanger has a casing with a gas inlet at one end, a transverse baffle opposite and spaced from the inlet, and a bank of heat exchange elements so mounted in the casing between the inlet and the baffle as to leave an unoccupied space between the casing wall and the heat exchange elements for gas to flow from the inlet to the baffle, the heat exchange elements being closer together adjacent the baffle than adjacent the inlet. In the gas turbine recuperator shown in Fig. 1, an annular bundle of tubes 11 arranged in concentric circles is enclosed by a casing 24 having a gas inlet 21. The tubes are spaced apart by tube plates 12, 13, a baffle 23 and an annular plate 27 and are more closely spaced at the baffle 23 than at the tube plate 12 since the circles of tubes in the baffle are of smaller diameter than those in the tube plate. In the annular plate 27 the tube circles are of larger diameter but are spaced more closely than in the baffle 23. In the tube plate 13 the tube circles are smaller in diameter than those in the annular plate 27. Cone shaped baffles 29 are also provided. In the form shown in Fig. 6, gas enters through the inlet 43 and is directed by a baffle 45 over two convergent banks 40' of tubes 41 which extend normally to the general direction of gas flow and are more closely spaced adjacent the baffle than adjacent the inlet. After passing through the passage 46 between the tube banks and the casing 44, the gas flows to the outlet 47 over tubes arranged in divergent banks 40A in which the tubes are more closely spaced adjacent the outlet 47 than adjacent the baffle 45. In a modification, the second pair of tube banks as well as the first pair is convergent towards the gas outlet. In a further form the gas flows over a single bank of tubes arranged transversely in a casing, part of which acts as a transverse baffle.

Patent GB-666378-A (GB)
Title: Improved process for the formation of a band or rod from high-molecular condensation products
IPC: C08G69/46
Filed: 1949-11-17
Abstract: Highly polymeric linear condensation products, e.g. omega polycaproic amide, is freed from most of its low molecular weight condensation products by breaking it up into small pieces, extracting it with water, alcohols, acetone, chlorinated hydrocarbons, benzene, &c., and then extruding it into the form of a band or rod at a temperature near its melting point, e.g. below its melting point and preferably at 150-215 DEG  C.  The band or rod is then made into threads, ribbons, &c., as by spinning.  The extraction may reduce the low m.w. products to less than 2 per cent, e.g. 1.5 per cent.  The pieces may be 0.5-10 mm. in diameter.  In one example amino caproic acid is melted, heated until it has a viscosity of 0.9, cooled, granulated to 2 mm. pieces and boiled for 2 hours in water, the part soluble in water being thus reduced from 9 per cent to 1.5 per cent.  The extracted mass is then dried, extruded at 208 DEG  C. into a band 4 X 20 mm., melted in a spinning apparatus at 240 DEG  C., and pressed through a spinning nozzle via a filter consisting of a plate made from sintered grains of stainless steel.  In another example a molten mixture of caprolactam and formic acid is similarly treated, the extraction in this case being first with toluene and then with hot water.  Reference is made to removing the low molecular weight condensation products (a) from a band by extraction with hot water, and (b) from molten polymer by means of high vacuum. Specifications 527,532, 542,128, 591,382 and 599,671 are referred to.

Filed: 1936-11-02
Abstract: 468,493. Copying telegraphy. SIEMENS & HALSKE AKT.-GES. Nov. 2, 1936, No. 29793. Convention date, Nov. 11, 1935. [Class 40 (iii)] In a facsimile telegraph, the characters to be scanned have their horizontal portions broadened as shown at 5, Fig. 1, so that the signal period is approximately equal to the interval between two signals, while at the receiver the signal is prevented from recording for a predetermined time so that the character is recorded as shown at 9, Fig. 1. This delay in recording may be obtained by applying the signal to a relay winding 20, Fig. 2, so that its field opposes that produced by a winding 18 energized with a constant current; a copper sleeve 17 tends to prevent the relay releasing its armature to record, so that the relay has a slow release but acts quickly. Alternatively, the signal is applied to the input of a valve 22, Fig. 3, over a condenser 28 and a resistance 29 which are so chosen that the relay 24 is actuated with the desired relay. The invention allows the frequency of the carrier wave to be reduced, and the effect of atmospherics on the receiver is minimized.
