Title: Improvements in and relating to hydraulic operating mechanism
IPC: F15B15/18
Filed: 1937-09-27
Abstract: 495,992. Hydraulic presses and other apparatus. BRITISH THOMSON-HOUSTON CO., Ltd. Sept. 27, 1937, No. 26150. Convention date, Sept. 26, 1936. [Class 69 (ii)] [Also in Group VIII] Hydraulic operating mechanism of the type comprising a cylinder containing a liquid and fitted with a piston having its head immersed in the liquid and an impeller carried by the piston and moving therewith for forcing liquid from the upper side to the lower side of the piston head for moving the piston upward in the cylinder, is provided with sealing means above the liquid level for preventing leakage of the liquid, a vent opening from the atmosphere to the space between the sealing means and the liquid, and means for closing the vent during the upward movement of the piston. An impeller 16 mounted in the piston head 13, 14 is rotated by an electric motor, the stator 28 of which is carried by the wall 29 of the piston, the motor shaft 17 running in a bearing 31 supported by the wall 30. A piston ring 32 is mounted with axial play in groove 33 in a collar 34 secured to the wall 24 ; vents 35 are provided. During upward movement of the piston from the position shown, frictional engagement with the wall of the cylinder 1 forces the piston ring to the bottom of the groove, thus closing the vents. As oil is withdrawn from the interior of the piston, the air pressure therein is reduced; this aids friction to hold the ring down. The reduction in pressure draws from the motor housing any oil which may have seeped thereinto, and when the motor is de-energized aids the return stroke. As the piston moves downward, oil returns to the interior of the piston, so that the air pressure rises ; at a certain point, the upward frictional force overcomes the pressure difference, and the ring moves up, uncovering the vents. The piston is thus able to return exactly to its initial position, and the inrush of air prevents the escape of fumes caused by the churning of the oil by the impeller. The invention is described as applied to an ironing press.

Title: Improvements relating to fluid pressure braking apparatus
IPC: B60T13/46
Filed: 1928-09-13
Abstract: 322,788. Leclair, L. J., Brackenbury, A. G., and Westinghouse Brake & Saxby Signal Co., Ltd. Sept. 13, 1928. Fluid-pressure.-Relates to vacuum braking apparatus in which a quick inshot valve device is subject to the pressure in the train pipe and in the brake cylinder and is adapted to admit air rapidly to the brake cylinder when train pipe pressure is increased on brake application. Brake cylinder pressure is adapted to be built up slowly thereafter through an apertured non-return valve in a bye-pass around the quick inshot valve so that relatively rapid release of the brakes may be obtained through this non-return valve. The invention is shown combined with the usual release valve. Air admitted to the train pipe nozzle 7, Fig. 1, on brake application passes by a passage 14 to the chamber 11 below an abutment 10 which rises and raises a ball valve 8 from its seat by means of a stem 9 and thus admits air from the atmospheric chamber 13 to the chamber 12 above the abutment and the brake cylinder passage 6 which is connected to the chamber 12. The resulting rise in brake cylinder pressure forces down the abutment 12 to reclose the valve 8 and further supply to the brake cylinder is maintained through a bye-pass 17 leading to the passage 6 and containing a non- return valve adapted to open to allow unrestricted brake-release and having a restricted aperture to allow slow building up of brake cylinder pressure. In a modified form, the stem 9, Fig. 4, passes through a part 22 in a spring pressed valve 23 which is opened by the air admitted past the valve 8, this air passing by ports 27 to the brake cylinder until the valve 23 recloses when the pressure in the chamber above the abutment 10 has attained a predetermined value, a restricted flow then takes place through the port 22 until the abutment 10 allows the valve 8 to close. In a further modification a port is formed through the side of the valve 23 and a valve face is formed on the abutment 10 which closes the end of the port 22 and the brake cylinder supply takes place in three stages, first past the open valve 23. secondly when the valve closes through port 22 and a port through the stem of the valve 23,. and finally the abutment 10 falls to allow direct communication through the port 22.

Abstract: 444,197. Door-operating appliances. JONES, W. H., 22, Pendennis Road, Wallasey, Cheshire. Sept. 14,1934, No. 26488. [Class 65 (i)] A spring closer and check for doors comprises a plunger 26, with a spindle 14 fixed thereto, slidable axially in a casing 10 on relative rotation, under the control of cams 41, 38, which are fixed to the spindle and casing respectively and are maintained in engagement by a spring 43 between the casing and the plunger, and resilient means, shown as a torsion spring 35, between the casing and spindle to store up energy on relative rotation of the parts in one direction so as to produce the return movement, the spindle having an opening for permitting the flow of fluid from one side of the plunger to the other, this flow being restricted during the return movement referred to. In the form shown, the spindle 14 has a longitudinal bore with transverse openings 45 and an opening at the lower end controlled by a valve 28 contained in the bore of the plunger and having a finger-knob 30 at the top for adjustment. The plunger also has a passage through it, closed by a spring strip 34 acting as a non- return valve. The casing is fixed to the top of the door, and the upper end of the spindle 14 is fixed to an arm 15 which is connected by a link to the door frame ; the link is adjustable in length and is provided with universal joints to accommodate the rising of the spindle 14 in the casing. Opening of the door causes rotation of the spindle, and the cams 38, 41 allow the spindle and plunger to rise under the action of spring 43, the spring 35 being stressed and fluid flowing freely from the upper to the lower part of the casing through the passage in the plunger controlled by valve 34. The door is closed by the spring 35, the spindle and plunger being forced down by the cams and the fluid passing to the upper side of the plunger through the restricted valve passage 28, which checks the motion; a transverse opening 46 in the upper part of the spindle allows the passage of fluid to lubricate the cam surfaces. The lower end of the spring 43 is carried in a cup 44 which is free to rotate in the casing as the plunger rotates. The cam surfaces are preferably helical, and may have a flat portion to allow limited rotation of the spindle without axial movement.

Title: Improvements in or relating to the recovery of phenols
IPC: C07C37/72
Filed: 1951-11-13
Abstract: Acid oils, e.g. phenols, cresols, catechol or xylenols are recovered from mixtures containing neutral oils by extracting with water at a temperature above 100 DEG  C. under pressure, diluting the aqueous extract of acid oils by adding water, removing residual neutral oils from the aqueous extract by azeotropic distillation with steam and separating the acid oils from the extract by means of organic solvents, e.g. oxygen or nitrogen containing solvents such as ethers, ketones or esters.  In preferred modifications, the mixture of acid oils and neutral oils is treated with water (particularly phenol containing waters such as waste waters from the dry distillation, gasification or hydrogenation of fuels) at above 100 DEG  C. under pressure, the aqueous extract is cooled to give a lower layer consisting of phenols and small amounts of water and neutral oils, water is added to this lower layer at 40-100 DEG  C. to dissolve the phenols and it is then subjected to azeotropic distillation together with the top layer.  The separation of the neutral oils may be improved by the addition of a solvent for neutral oils such as hexane to the initial hot water extract.  The process is conveniently carried out continuously as a multi-stage counter-current process and dephenolized water resulting from the final organic extraction step may be re-used in the process.  In an example a fraction boiling at 150-120 DEG  C. obtained by distilling brown coal tar is extracted by counter-current with dephenolized water at 200 DEG  C., the aqueous extract is cooled, the lower layer is dissolved in phenol-containing waste water and this solution, together with the upper layer is subjected to azeotropic distillation to remove neutral oils followed by extraction of the residual aqueous phenols with butyl acetate. Specifications 273,351, [Class 2 (iii)], and 517,618 are referred to.

Title: Improvements in or relating to television receiver systems including a plurality of cathode ray tubes
IPC: H04N3/30
Filed: 1937-10-01
Abstract: 503,025. Television. MULLER, E. N. Oct. 1, 1937, No. 26625. Convention date, Oct. 1, 1936. [Class 40 (iii)] A picture is reconstituted by a plurality of cathode-ray beams, to which deflecting potentials or forces are supplied selectively from generators or amplifiers 401, 402 in which the rise in voltage corresponding to the active scanning deflection occurs at different times for the various cathode-ray tubes. The highest voltage associated with each amplifier is less than twice that required for the active deflection. An equal number of mirror drums rotating at framing frequency may co-operate with the cathode-ray tubes to reconstruct the corresponding zones a<1> ... d<3> of the image, Fig. 4 (not shown). The deflecting potentials and the scanning movement are of sufficient amplitude to cause overlapping of the scanning by adjacent tubes on the viewing screen in order to prevent sharp changes. For this purpose the permeability of masks 201, 211, 221 for the tubes increases gradually close to the margins of the respective zones, or -the intensity of the cathode ray is decreased in that region by potentials associated with the scanning. As shown, a common source 301 of saw-tooth potentials of the scanning frequency feeds the inputs of the amplifiers 401, 402, which are given such staggered biases 51i ... 53s through limiting diodes 512, 514, 522, 524 that the amplifiers pass successive overlapping portions of the stroke of the generator 301, Fig. 3 (not shown). The return stroke is then virtually simultaneous for all tubes. According to a modification, two generators are associated with alternate groups of tubes and generate saw-tooth waves with a frequency which is a sub-multiple of the scanning frequency, the waves in one set overlapping those in the other, Fig. 5a (not shown). The deflecting potential for each tube is obtained through an amplifier . which suppresses the undesired parts of the waves, Fig. 5b (not shown). In this arrangement the return stroke in each tube occurs immediately after the active forward stroke. The picture signals are distributed electronically or mechanically to output valves associated with the tubes, not more than two of which are effective at a time. In another modification, the deflection is obtained from a plurality of phasedisplaced sinusoidal waves, of which a portion of the upward stroke is selected to deflect the spots in the tubes which trace different portions of the image, Fig. 6 (not shown). The sinusoidal waves may be generated by a dynamo on the same shaft as the distributer of the picture signals. Specification 467,195 is referred to.
