Abstract: 865,780. Structural members. GOLLNOWWERKE A. G. July 30, 1957 [July 30, 1956], No. 24200/57. Drawings to Specification. Class 20(2) [Also in Groups XXII and XXXIII] A prestressed structural tube is made by inserting filling material into the tube, hermetically closing its ends and, by external action, causing a physical or chemical change in the filling material resulting in a superatmospheric pressure within the tube. Light metal, steel or plastics tubes of various crosssections and shapes and tubes separated into longitudinal and lateral compartments are described. Solid, liquid or plastic filling material introduced at low temperatures and activated by external heating or by a blow destroying a glass separating two chemically reactable materials or an expandable material and an expanding agent are referred to. The tube may be coated internally with lacquer, plastics, rubber or metal. The tube may be internally divided either laterally or longitudinally and the compartments stressed to different pressures. The ends of the tube are blanked off by plates having eyelets attaching an internal tension member. Index marks may be made on the outside of the tube to indicate the extent of expansion during prestressing.

Title: Control mechanism for fire doors
IPC: F23M7/00
Filed: 1950-10-06
Abstract: 677,119. Preventing fires. LANEY, J. P. DE. Oct. 6, 1950. No. 24490/50. Class 47 (ii). [Also in Group XXV] A fireproof door of the rolling shutter type adapted for both manual and automatic operation is mounted on a rotary drum 3 containing a shaft 6 to the outer end of which is secured a disc 7 connected by a fusible link to a support bracket 1 for preventing rotation of the shaft under normal conditions of operation. A sleeve 8 fixed to the bracket has secured to its inner end a collar 11 providing an anchorage for one end of a spring 12, the other end of which is anchored to a collar 10 secured to the shaft. A recessed collar 22 secured to the drum is formed with longitudinal slots engaged by pins 21 on a nut member 18 which is mounted on a screw-threaded extension of a member 15 secured to the inner end of the shaft. Mechanical operation of the door downwardly carries the nut member away from the member 15, and operation upwardly carries it towards the latter until movement of the door is arrested by the engagement of abutments on the respective members. The abutments serve to transmit torque from the spring to the drum for lowering the door if the link fuses when the door is raised. Downward movement of the door is cushioned by a spring 30, one end of which is anchored to a collar 29 secured to the inner end of a non- rotatable shaft 27 and the other end to a collar 28 secured to the drum. Spring 12 may be so stressed initially that it reaches its neutral position before the door is fully closed, thereafter being wound up in the opposite direction to provide additional cushioning effect.

Title: Improvements in and relating to the production of thermoplastic polycondensation products
IPC: B01J14/00
Filed: 1964-06-12
Abstract: <PICT:1007302/C3/1> Thermoplastic condensation polymers are prepared by feeding the viscous starting materials or solutions thereof into a heated tube, along the inner wall of which they are moved by a worm conveyer, to the exit point, where the product is withdrawn, the loading of the tube being adjusted so that the central part of the tube is left free to conduct away volatile reaction products and possibly solvent vapours.  The worm conveyer may also be heated, and the heated tube may be maintained under reduced pressure. Suitable subjects for this process are polyamides and polyesters, including polycarbonates and polyesteramides.  Instead of monomeric starting materials low molecular weight precondensates may be used.  In examples precondensates from (1) diphenyl carbonate and bisphenol A, and (2) terephthalic acid bis-(hydroxyethyl) ester, are passed into a tube of 100 mm. diameter and 600 mm. long at rates of 5.0 and 1.8 kg./hr., at 270-300 DEG  C. and 270-280 DEG  C. and at worm speeds of 20 and 40 r.p.m., to give mean residence times of 8-10 and 8 minutes respectively, under 1 mm. Hg. pressure.  Fig. 2 describes a suitable form of apparatus wherein the worm (2), rotated by a drive (3), conveys material along the heated tube (1) from the entry (4) to the exit (5) where the product is removing by a geared pump or another worm (7), any volatile material being exhausted through a pipe (8).

Title: Improvements relating to the generation of water gas

Filed: 1937-09-09
Abstract: 502,147. Water - gas generators. BALFOUR & CO.; Ltd., H. (Pintsch Akt.- Ges., J.) Sept. 9, 1937, No. 24571. [Class 55 (i)] The usual " blow " stage of a water-gas generator B, having a superimposed retort A, is followed by an up-run with steam admitted to the superheater F through an injector J which withdraws gases and vapours from the retort A to mix with the up-running steam. This stage may be preceded by a short up-run with steam only. Water-gas is withdrawn through conduit M. The up-run may be followed by a down-run by admitting the same mixture of gases from the injector J to the top of the generator at Q, water-gas being withdrawn below the grate through conduit R. The downrun may be modified by shutting off the injector and admitting steam to the superheater through pipe 0 to flow downwardly through the retort, the mixed gases then downrunning the generator as before. Reference has been directed by the Comptroller to Specification 473,948.

Abstract: 1459686 Brake relay valves WERKZEUGMASCHINENFABRIK OERLIKONBUHRLE AG 4 June 1974 [6 July 1973] 24615/74 Heading F2F In a relay valve for controlling operation of a pneumatic brake cylinder 21, when the pressure in a chamber 16 connected to a main brake pipe 18 equals that in a chamber 15 connected to a control reservoir 17 a spring 41 depresses pistons 13, 14 and stem 11 causing the latter to disengage valve disc 31 which engages seat 30 on a piston 24, the brake cylinder thereby being isolated from air reservoir 36 and connected to vent port 43 via chamber 25, passage 12 in stem 11 and chamber 20. When the pressure in the main brake pipe is released somewhat to effect partial braking, pistons 13, 14 and the stem move upwards to cause the stem to abut the disc 31 and disengage it from seat 30, thereby disconnecting cylinder 21 from vent port 43 and connecting it instead to the reservoir 36, the pressure in cylinder consequently rising until the disc is reseated as a result of the outlet pressure acting on piston 14. If, on the other hand, the pressure in the brake pipe is reduced to zero to effect full braking, then the outlet pressure acting on piston 14 is unable to reseat disc 31, but in this case the outlet pressure acts to raise piston 24 against the bias of an adjustable spring 33 to engage the seat 30 with the disc. The upper side of piston 24 is permanently vented via port 28.

The arm 14 of the strip 7 and the disc 12 are rigid with a sleeve 9 rotatable on a shaft 8 to which the set pointer 4 and the potentiometer arm 32 are rigidly secured. The shaft 8 has a knob 5 outside the housing 1. A friction wheel 13 driven by the servomotor is spring-urged into contact with the disc 12 to drive it. Stops 18, 19 on the disc 12 limit its rotational travel. A recess 20 with ramped ends 20', 20" in the disc periphery prevents wear of the friction wheel 13 when the disc 12 reaches its limit of travel. The disc 12 carries a second potentiometer arm 30 which contacts a resistance wire 28. The two potentiometers 28/30 and 29/32 are part of an electrical control circuit. The potentiometer wires 28, 29 are supported by a stationary insulating disc 25. Preferably the end 7a of the strip 7 is secured to a second disc (not shown) rigidly secured to the sleeve 9 between the plate 10 and the disc 12.
