Title: Improvements in and relating to steam generators
IPC: F22B1/22
Filed: 1930-12-05
Abstract: 367,484. Methods of generating steam. AKT.-GES. BROWN, BOVERI, ET CIE, Baden. Switzerland. Dec. 5, 1930, No. 36708. Convention date, Dec. 16, 1929. [Class 123 (ii).] To promote the water circulation and to facilitate the steam separation in a steam boiler heated by gases which are generated by explosion or by continuous conibustion under high pressure in an internal combustion chamber 1 and which are passed over the boiler surfaces 3 at a velocity of from 200 metres per second to the velocity of sound, the main part of the water in the steam separating space 5 is led to the water circulation pump 16 through return passages 17 within the boiler casing, and the wet steam is conducted into an exterior separator 20 which discharges its water into the return passages. The gases pass from the combustion chamber through tubes 2 inside water tubes 3 connected to upper and lower water chambers. Part of the water in the upper chamber passes downwards through an annular opening 6 into a space 7 communicating with the return passages. The other part passes upwards through nozzles 11 so arranged as to give the water a circular motion. Water returns from the space above the nozzles through tubes 14, and the separated steam is led to the separator 20 together with the steam conducted from the space 7 through tubes 10. A number of boilers may have a common circulation pump and may have their external separators connected to common water supply and steam delivery pipes.

Title: Tunnel diode sensing circuit
IPC: H03K3/315
Filed: 1965-08-26
Abstract: 1,104,720. Data storage. INTERNATIONAL BUSINESS MACHINES CORPORATION. 26 Aug., 1965 [23 Sept., 1964], No. 36762/65. Heading G4C. [Also in Division H3] A circuit for reading out the state of a bistable element (e.g. magnetic core, transistor or tunnel diode circuit) represented by ESL and RSL comprises a pair of tunnel diodes TD 1  and TD 2  having fixed bias EB, a sawtooth generator ER continuously operating to shift the loadline, and strobe pulses Es to shift the load-line further for given periods. The tunnel diodes are switched to their opposite voltage state whenever the combined level of ESL + ER + Es exceeds a certain threshold. The strobe pulses from Es occur only during the part of the " read " cycle when output pulses ESL are obtained, and noise at other parts of the cycle cannot cause false operation or blocking (Fig. 3, not shown). More than one of the sawtooth waves appear during each strobe pulse and two output pulses are obtained during each of the strobe pulses, the time-separation of these depending on the sign of the signal ESL. This time-separation is detected by passing the two pulses through a delay line D matched at the end and followed by a differentiating circuit CRN. The delayed differentiated output is compared with the second pulse which has passed directly through RM and if the two coincide the tunnel diode TD 3  will be switched to give an output at 18.

Abstract: 907,662. Transistor pulse circuits. BRITISH TELECOMMUNICATIONS RESEARCH Ltd. Nov. 18, 1959 [Nov. 20, 1958], No. 37407/58. Class 40 (6). The output of a common emitter pulse circuit is shunted by a further transistor having its collector connected to the emitter of the first transistor and its base fed with the inverse of the input waveform so that the further transistor is conductive when the first is cut off. In the Figure, pulses are applied through the emitter follower transistor T1 to an output terminal O feeding a capacitive line. During the negative going part of the input pulses transistor T1 conducts and rapidly charges the line while during the positive portion transistor T1 is cut off but due to the pulse fed through capacitor C transistor T2 becomes conductive to discharge the load so that sharp leading and trailing edges of the output pulse are obtained. A diode D prevents the base of the transistor T2 from being driven positively.

Title: An improved process for the production of curly fibres
IPC: D01D5/22
Filed: 1954-12-29
Abstract: In the production of helically-curled fibres by drawing continuous filaments from a molten source of thermoplastic material, e.g. methyl methacrylate, polyethylene or vinyl polymers, each filament is stretched on one side along its entire length by pulling it continuously through an arcuate path to deform it curvilinearly while it is being cooled to a temperature below that at which it is inelastic.  As shown in Fig. 2, streams of molten material emerging from staggered orifices in a feeder 11 are attenuated into filaments 13 and gathered at a shoe 14 to form a strand 15 which is wound on a tube 16 <PICT:0796876/IV (a)/1> <PICT:0796876/IV (a)/2> <PICT:0796876/IV (a)/3> <PICT:0796876/IV (a)/4> and, in the zone wherein the material changes from a thermoplastic inelastic state to a solid and elastic state, the molten stream passes over a water- or air-cooled rod 20 of heat-resistant material such as graphite and of a diameter corresponding to the tightness of curl required. Lubricating fluid may be applied to the strand.  Two cooled rods may be used to form the curl, one rod deforming the filament and the other changing its direction of travel so that it is drawn in a straight path to the winder while remaining in contact with the rods for a maximum number of degrees, e.g. 270 degrees, over the curvilinear surfaces thereof. In the curling apparatus of Fig. 4, filaments 53 pass between mated water-cooled members 50 and 51 of heat-resistant material which may be mounted in a metal holder associated with means (not shown) for adjusting the relative disposition of the members and filaments.  The apparatus of Fig. 5 comprises an adjustable, cooled, curling member 60 and cooled members 61 and 62, all providing staggered fibre-contacting surfaces in the path of the filaments 63; in similar apparatus, the members 60, 61, 62 are replaced by fixed or rotatable rods which are not water-cooled, Figs. 6 and 7 (not shown).  As shown in Fig. 8, streams of material flowing from a source 80 through orifices in a feeder 81 are attenuated to filaments 83; staggered jets of fluid, e.g. air or steam, issuing from blowers 84 and 85 and limited by a baffle 86, impinge on the filaments, when the latter are in the appropriate transition state, to produce the curled formation.
