IPC: B07C5/34
Filed: 1954-02-16
Abstract: 758,850. Testing transparent containers photo-electrically. GENERAL ELECTRIC CO., Ltd., and THOMPSON, W. G. Feb. 16, 1955 [Feb. 16, 1954], No. 4575/54. Class 40 (3). To detect dirt particles on the inside only of a transparent container 2 light from a source 1 transmitted through the container to a cell 3 is compared with light from a source 4 reflected from the outside of the container to a cell 5. The bottle is slowly rotated and moved up and down with respect to the light sources. Dirt on the inside of the bottle reduces the light of cell 3 and an electric comparison circuit rejects the bottle. The bottle may be filled with water during inspection to prevent spurious signals caused by water droplets inside the bottle. -

Title: Pressure regulating mechanism and flow distribution means for enclosures such as aircraft cabins
IPC: B64D13/02
Filed: 1954-02-22
Abstract: 786,479. Fluid-pressure servomotor control systems; valves. GARRETT CORPORATION. Feb. 22, 1954 [March 16, 1953], No. 5104/54. Class 135. An air-flow control valve suitable for application to pressurized aircraft cabins comprises a pressure-responsive control element subject on one side to a control pressure and on at least a portion of the other side to a modifying pressure which is varied in response to flow through the valve. One embodiment is similar to the valve described in Specification 728,480 with the addition of a tube 95, Fig. 2, having an open end adjacent the valve member 34 and communicating through passages 108, 111, 115 with a chamber 57 to furnish the modifying pressure acting on the pressure responsive member 54, 71 in opposition to the control pressure which is effective in a chamber 85. The pressure sensed by the open end of the tube 95 depends upon the flow through the valve. The tube 95 is adjustably positioned by a nut 105, and instead of facing downstream as shown, it may face upstream. Alternatively, the tube 95 may be fixed to the valve member with its open end facing the valve seat 37. In another embodiment, the flow sensing tube opens adjacent one of the closure members of a double-beat valve of the kind described in Specification 652,423. The valves may be used in a system in which a cabin 11, Fig. 1, is pressurized by a supercharger 12 and discharges through chambers A, B to atmosphere. Valves 16, 26 control the connection of the cabin 11 with the chambers A, B respectively to maintain the rates of flow through those chambers in fixed proportion. .A pressure control unit 19, e.g. as described in Specification 718,674, is common to both valves 16, 26. The pressure in chamber B is controlled by an outflow valve 21 under the control of a regulator 23. In another embodiment a valve member 179, 182, 202, Fig. 6, is subject on its upper side to control pressure in a chamber 215 and on its lower side to pressure in a chamber 195 which is connected by a pipe 198 to a point 196 in a throat of the valve so as to sense a pressure related to flow. The chamber 215, which has a bleed 217 to atmosphere, is connected through a port 216 to pressure-responsive control devices comprising a low-differential control 240, an isobaric control 241, a climb and dive control 242, which controls the rate of change of pressure, and a high differential control 243. These devices actuate valves which control flow of air through an opening 237 from the cabin to the chamber 215. Instead of the main valve being combined with the control devices as shown it may be connected to the control chamber of another outflow valve or to a separate regulator unit.

Title: Improvements in or relating to heat exchangers
IPC: F28F1/12
Filed: 1962-02-09
Abstract: 994,703. Heat exchangers; forced flow steam boilers. BABCOCK & WILCOX Ltd. Feb. 9, 1962 [Feb. 9, 1961], No. 5176/62. Headings F4A and F4S. A heat exchanger comprises a helically wound tube of varying pitch enclosed within a cylindrical casing in which the heating medium flows axially over the surface of the tube coil. The tube is provided with means, such as fins or grooves, for promoting heat exchange and these are so arranged that while the inclination of the tube to the direction of flow may vary owing to the varying pitch, the inclination of all similarly disposed portions of the fins or grooves on one side or the other of the tube is the same and is kept to a minimum in order to minimize turbulence. The fins may be discrete or may form the convolutions of a helix on the surface of the tube in which case the pitch of the finhelix is varied as indicated in Fig. 1 to achieve the desired inclination. With this arrangement the inclination of the portions of the fin-helix to the direction of flow is inevitably greater on one side of the tube than on the other. The smaller inclination is preferably less than 10 degrees. To accommodate the larger inclination short conduits 7 may be mounted in appropriate places to deflect the flow suitably in the region of the particular fin or groove. A tube 2 is wound helically at varying pitch to form an economizer section 3, a vapour generating section 4 and a superheater section 5 of a steam generator. The fin-helix is indicated by reference numeral 6. Where a number of coils of differing radii are disposed coaxially within each other, Fig. 2 (not shown) the finhelices may be oppositely handed on alternate coils in order that the flow of heating medium in the annulus between any pair of coils should be diverted in the same direction by the opposed fins. Where the opposed fins are not inclined in the same direction short bifurcated conduits may be interposed between the coils to deflect the flow to a direction suited to the fins on each particular tube.

Title: Improvements in and relating to condensation products of ureides and formaldehyde
IPC: C08G12/10
Filed: 1947-02-24
Abstract: Trichlorethylidenediureide (chloraldiurea) is reacted with formaldehyde in aqueous solution to give soluble and insoluble condensation products suitable for use in moulding powders, as coating compositions giving hard glossy films on airdrying or stoving and for impregnating textiles.  The condensates are soluble in aromatic hydrocarbons.  Condensation may be carried out under acid or alkaline conditions and the syrupy product is stable under alkaline conditions but under acid conditions is precipitated on cooling; this can be prevented by adding polyhydroxy compounds, e.g. glycols, pentaerythritol, glycerol or half acetal thereof or an ester containing more than one free hydroxyl group per mol, e.g. esters of tartaric acid, bis(hydroxyethyl) sebacate or a polyglyceryl phthalate.  The condensate may be modified by heating it with a monohydric alcohol, prolonged treatment giving products compatible with nitrocellulose, polyvinyl chloride, urea-formaldehyde and phenolic resins.  In examples: (1) 3 parts of the diureide are heated with 10 parts 40 per cent formaldehyde until a clear solution is obtained.  On cooling and adding cold water a soft resin precipitates; (2) the reaction is carried out with formaldehyde which has been made alkaline by addition of conc. ammonia; on cooling, the syrup remains clear after storage for some months; (3) and (4) the resin obtained in (1) is reacted with n-butanol, (a) for about 30 minutes, (b) for 3 hours, products insoluble and soluble respectively in aromatic compounds being obtained; (6) amyl alcohol is substituted for the butanol; (7) the reaction is carried out in presence of ethylene glycol; (8) in presence of pentaerythritol chloral.
