Abstract: 882,991. Light projectors. PHILIPS ELECTRICAL INDUSTRIES Ltd. March 11, 1960 [March 14, 1959], No. 8665/60. Classes 75(2) and 75(4) A lighting fitting especially for marking airfield runways comprises a lamp, the light source of which is located substantially at the foci of two oppositely directed reflectors, each of which is mounted in a slide displaceable outwards from an inner operative position in a direction parallel to the axes of the reflector, the slides being connected together by draw springs. In the form shown, an incandescent lamp 3 is mounted on a base 2 so that the filament 4 is at the foci of two paraboloidal reflectors 5a, 5b (not shown) in their inner operative position. The reflectors are carried by supports 9a, 9b mounted in slides 10a, 10b movable along a frame 11 and guided by steps 12 on the edge thereof, the slides being linked by springs 15. The inner edges of the slides 10a, 10b are circular, the centre of the circle being on a vertical axis through the lamp, and rest against studs 17b on the slides. Small adjustments of the reflectors in a horizontal plane may be made by loosening screws 19a, 19b which hold the slides to the supports. Stops 20 on the base limit the inward movement of the slides and pawls 22a, 22b on the outer ends of the slides can be brought into engagement with the ends of the frame 11 to retain the slides in the outward position when required. The arrangement allows of easy access to the lamp, e.g. for cleaning.

Title: Improvements in the manufacture and production of triarylmethane dyestuffs
IPC: C09B11/22
Filed: 1936-03-25
Abstract: Triarylmethane dyestuffs capable of being converted into complex metal compounds are obtained by oxidizing the leuco compounds produced by condensing an ortho hydroxycarboxylic acid of the benzene series substituted by an aldehyde group with a secondary or tertiary aromatic amine, the components being selected so that the product contains a water solubilizing group other than the carboxylic group of the ortho hydroxycarboxylic acid component.  The water solubilizing groups are the carboxylic, sulphonic, hydroxyalkyl and hydroxyalkylether groups.  In examples: 2-hydroxy - 3 - methyl - 5 - aldehydobenzene - 1 - carboxylic acid and 2-hydroxy-5-aldehydobenzene-1-carboxylic acid are used as the ortho hydroxycarboxylic acids containing aldehyde groups and these are condensed with b -(2-methylphenylamino)ethanesulphonic acid, b -(N-butyl-N - phenylamino)ethanesulphonic acid, b -benzyl - metatolylamino)ethanesulphonic acid, b  - (N - ethyl - N - phenylamino)ethane sulphonic acid, N - ethyl - N - sulphobenzylaniline, 1 - N - butyl - N - phenylaminopropanesulphonic acid, 1 - N - hydroxyethyl - N - phenylaminoacetic acid, 1-(N-butyl-N-phenylamino-)2-hydroxypropane-3-sulphonic acid and N-dihydroxyethylaminobenzene.  The use of 2-hydroxy-3-aldehydobenzene-1-carboxylic acid and the alkyl, alkoxy and sulphonic acid derivatives thereof is mentioned.  These aldehydes may be prepared from the corresponding halogen compound containing the same number of carbon atoms and hexamethylenetetramine according to the process described in Specification 5533/03, [Class 2 (iii)]. The dyestuff may be used for dyeing wool, silk, leather and paper and they give lakes with calcium or barium salts or phosphorus-tungsten or molybdenum acids.  The complex chromium compounds of the dyestuffs are suitable for colouring spirit lacquers.  1 - (N - butyl - N - phenylamino) - 2 - hydroxypropane-3-sulphonic acid is prepared by condensing N-butyl aniline with epichlorhydrin and treating the N-butyl-N-phenylaminohydroxychlorpropane with sodium sulphite.

Title: Self-sealing couplings for use in pressure fluid systems
Inventor: SMITH RALPH ANDREW
IPC: F16L37/30
Filed: 1955-03-30
Abstract: 829,096. Pipe couplings. I. V. PRESSURE CONTROLLERS Ltd. March 29, 1956 [March 30, 1955], No. 9302/55. Class 99(1). A coupling device for a circuit comprising pressure fluid flow pipes and return flow pipes comprises a spigot member 42A, Fig. 2, engaging a socket member 1, Fig. 1, each member having coaxial passages for the pressure fluid and return flow, which passages are closed by valves when the members are disconnected and opened by the action of connection. The spigot 42A comprises a stationary thrust member 51, forming the pressure flow pipe, on which slides a valve 60 urged by a spring 55 on to a seat 65 to cut-off the return flow fluid entering at 70 and flowing through the annular passage around the member 51, the valve 60 also blocking ports 58 in member 51. The socket 1 comprises a thrust member 32 in which slides a piston valve 23 forming the pressure flow pipe and around which slides a valve 39 in the return flow passage urged on to a seat 36. When the member 42A is inserted into the socket 45 of the member 1 the thrust member 51 forces back the piston valve 23 (see lower part of Fig. 3) until the ports 58, 28, become interconnected by an annular space 33, permitting flow through the pressure fluid pipe, and the valves 60, 39, are forced off their seats 65, 36, by the thrust member 32 and the member 42A respectively, permitting return flow fluid entering at 70 to flow through the annular passage around the members 51, 32 and leave at 71. After a predetermined travel the member 39 contacts a step 1A on the body 1 and further movement of the member 42A to the right causes the body 1 to be moved against a spring 13 relative to a locking sleeve 16 having a conical portion 17 which forces spring loaded pins 9 inwards to engage behind a flange 50 on the spigot 42A and lock the spigot in position, the sleeve 16 being held in position by a clamp. Sealing rings 59, 37, in the valve 60 and member 32 prevent leakage of fluid from the pressure pipe to the return pipe. In a modification, Figs. 4 and 5 (not shown), the sealing rings are positioned in recesses in the parts 51, 23, and are acted upon by the pressure in the return flow passage. The inlet and outlet 70, 71, for the return flow fluid may be arranged coaxially with the pressure flow passage.

Title: Improvements in and relating to valve gear for mixed pressure turbines
IPC: F01D1/02
Filed: 1919-04-14
Abstract: 147,975. British Thomson - Houston Co., and Halliwell, R. F. April 14, 1919. Regulating.-Governing and valve mechanism is provided whereby a mixed-pressure turbine is driven by high-pressure steam when the low pressure supply is insufficient. The high and low pressure valves are each operated by a separate servomotor, a single pilot-valve controlling both motors. The arrangement is such that when the low-pressure steam supply is sufficient, the lowpressure valve is opened in preference to the highpressure valve. The servomotor 15 for the lowpressure valve 1 is operated by oil conveyed to it by pipes 33, 27 having extensions 32, 38 communicating with the servomotor for the high-pressure valves (not shown), the supply of oil to these pipes being controlled by a governor-controlled pilotvalve 18. The flow of oil to the underside of the piston 16 to open the valve 1 is regulated by a valve 26 operated by a pressure-regulator 12, the upper end of which is connected by a pipe 25 to the valve 1, while its lower end is open to the atmosphere. Assuming the turbine to be running on low-pressure steam with the high-pressure valves shut, a diminution in the low-pressure supply will cause the piston 13 to rise, thereby lifting the valve 26, and connecting the underside, of the piston 16 with the exhaust 28. The piston 16 therefore descends and shuts the valve 1, thereby through a link 21 raising a link 31 and valve 18 to supply oil to the pipe 38 and operate the servomotor 23 to open the high-pressure valves, which continue to open until the descent of the rack 22 lowers the link 31 and valve 18 sufficiently to shut off oil from the pipe 38, and equilibrium is again established. Valves 36, 37 are so arranged as to offer a resistance to the flow of oil in a direction to open to highpressure valves and to shut the low-pressure valve respectively, and have springs so adjusted that when the flow of oil along pipe 27 is unrestricted, as shown, the valve 1 is opened in preference to the high-pressure valves. A trip 11 is adapted to be manually released to close the valve 1 on emergency.
