Title: Improvements in or relating to devices for reproducing images comprising a cathode-ray tube
IPC: H01J29/89
Filed: 1950-12-14
Abstract: 701,270. Cathode-ray tubes. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Dec. 14, 1950 [Dec. 17, 1949], No. 30544/50. Class 39(1) [Also in Group XL(b)] In a cathode ray image reproducing apparatus having a fluorescent screen, such as a television tube, oscillograph or indicator, a number of thread or scale-like bodies, are arranged on end or on edge respectively on and fixed to the image window or a separate light transmitting plate between the window and the observer, and extend substantially parallel to the tube axis, their cross sectional dimensions parallel to the window or plate being small in comparison with the diameter of the screen or plate. This expedient improves the contrast by reducing the space angle from which external light can strike the image window. The ratio between the length and the spacing of the bodies may be such as to allow light to impinge on the image window through an angle of 60 degrees with the tube axis. The ends and / or sides of the bodies may be blackened or frosted so as to further improve the contrast. Another expedient is to partly fill the spaces between the bodies with synthetic resin in which a light absorbing substance is dispersed. A plurality of parallel threads, for example of artificial silk, may be used. They are dyed to make them lightabsorbing and then further treated to give them a matte surface. Their conductivity may be improved by coating them with metal. Alternatively suitably treated mica scales may be used. In one form, Fig. 1 (not shown), threads are arranged directly on the outside of the tube wall. In another form, Fig. 2 (not shown), the cathode ray tube is enclosed in a cabinet having a glass anti-implosion plate on the outer surface of which the bodies are arranged. In another form, Fig. 3, the cathode ray tube 8 has an image screen 13 coated with a metal layer 12. During manufacture, a high D.C. potential is applied between the metal layer 12 and a metal bowl 9 holding glass or mica threads 10. The threads 10 are charged by the field and attracted to the end wall of the tube, their mutual repulsion assuring their disposition in parallel relationship thereon. An agglutinant is provided on the end wall to secure the threads 10 in position. If the cathode ray tube has no metal layer 12, a positively charged grating may be arranged between the end wall and the bowl 9, or alternatively the outer surface of the end wall may be made conducting either permanently, for example by a coating of tin oxide, or temporarily, so that the high potential may be applied thereto. The image window may be of glass or synthetic resin.

Abstract: 743,337. Locking levers; controlling change-speed gearing. ROLLS-ROYCE, Ltd. Dec. 2, 1953 [Dec. 2, 1952], No. 30597/52 Classes 80(2) and 80(3) An operating lever 10, particularly for a vehicle steering column controlled change-speed gearing, is adapted to be moved in steps each step corresponding to an application of the operating torque. The lever 10 is mounted on a rod 12 for rotation with a radius arm 14. The arm 14 has a limited rotation. relative to a second radius arm 17 determined by pins 19 thereon and carries a roller 16 at its end which co-operates with a V- notch 21 in a pawl 20 pivoted on the arm 17. A blade spring 24 serves to urge the pawl 20 against the roller 16 and thereby centralise the arm 14 between the pins 19 of arm 17. Centralised on the pawl 20 between pegs 48 is a detent 27 with a nose 28 and acted upon by a blade spring 29. The detent 27, 28 is adapted to operate with a series of abutments 31-36 on a fixed structure 30. The arm 17 is secured to one end of a driven shaft formed in two parts 37, 38 connected by a lost-motion coupling 39, 40 and a rubber sleeve 41. To the other end of shaft 37, 38 is secured a toothed wheel 42 which co-operates with a spring-loaded locating plunger 43. In operation from the position shown, in which the detent 28 lies opposite one of the abutments 31-36, a torque is applied to lever 10 in the desired direction of movement and the arms 14 and 17 move together until the lost-motion between the shaft parts 37, 38 is taken up and the detent 28 moved out of line with the abutment 32. The arm 14 then moves relatively to arm 17 and roller 16 forces pawl 20 together with detent 28 outwardly. The arm 14 then engages one of the pins 19 and the two arms 14 and 17 again move together until the detent 28 abuts the next of the abutments 31-36, whilst the spring plunger 43 drops into the next tooth of the wheel 42. Further movement of the operating lever 10 by continued application of the torque thereto will not effect any further movement of the lever and arms 14 and 17. If the operating torque on lever 10 is released the arm 14 is then centralised with respect to arm 17 and detent 28 assumes a position opposite the abutment it was engaging. The mechanism can then be operated for a further step of movement. Dogs 46, 44 an the shaft 12 and arm 17 can be engaged for an overriding direct control of shaft 37, 38. A modified arrangement is described in which a pawl corresponding to pawl 20 is pivoted on driven arm 17 and carries two pegs which in any adjusted position are radially aligned with, and on either side of, one of a series of fixed abutments. These pegs are adapted to move radially, on an operating movement, for one of them to engage the next abutment and limit the movement to one step. The pegs are disengaged on release of the operating torque as before to allow a further movement.

Title: Improvements in photometers
IPC: G01J1/12
Filed: 1920-10-29
Abstract: 153,323. Siemens & Halske Akt.-Ges. Nov. 5, 1919, [Convention date]. Comparison photometers.- The light from the standard source of light L2 or the light L, to be measured is led through a transparent body d to a surface of comparison i, the construction and arrangement of the transparent body being such that the light rays enter and pass out at end'surfaces and are led through the bcdy in its longitudinal direction so that total reflection takes place from the whole of its side surface. The surfaces of comparison l, m, for the lights L2, L1, may be in the same or different planes, one light being arranged in a casing a and the other in an opaque casing c. In the example shown in Fig. 2, the glass body d is in contact with a separate glass plate h dulled on its rear face or covered with milk glass, and arranged between rings k. Direct comparison may thus be effected, the glass body providing a sharp line of demarcation. In another example, the glass body projects beyond the surface of comparison for the light L1, and in a further example, the light exit end of the transparent body extends through an opaque irregularly reflecting mass having a surface of comparison in the same plane as the end surface of the transparent body.

Patent GB-601286-A (GB)
Title: Improvements in or relating to internal combustion engines
IPC: F02B37/18
Filed: 1945-11-15
Abstract: 601,286. Fluid-pressure servomotor-control systems. AKTIEBOLAGET GOTAVERKEN. Nov. 15, 1945, No. 30653. Convention date, Dec. 13, 1944. [Class 135] [Also in Group XXVII] In an internal-combustion engine, e.g. a two-stroke engine, having an exhaust-driven, preferably two-stage, turbine 3, Fig. 1, driving a compressor 5 which supplies scavenging and supercharging air to the engine through a conduit 6, the turbine is supplied, through a conduit 1, with exhaust gases which have been substantially finally expanded in the engine, and through a conduit 2, with exhaust gases at a higher pressure, whilst a'byepass 7 controlled by a valve 8 permits, under certain conditions of exhaust gas pressure and scavenging air pressure, the discharge direct to the atmosphere of exhaust gases in the conduit 1. The valve 8 comprises a double-beat lift valve member 9, Fig. 2, urged by a spring 12 towards the open position and closed by fluid pressure in a chamber 13 acting on a piston 14, the chamber 13 being connected by a conduit 15 to a control valve 16 adapted to connect the conduit either with a pressure fluid supply 17 or with an exhaust 18. A bellows 21, connected by a pipe 23 to the scavenging air conduit 6 bears at the lower end of the valve 16, whilst a spring-assisted bellows 22 connected by a pipe 24 to the exhaust conduit 1 bears at the other end of the valve. To prevent the exhaust gases from coming into contact with the bellows 22, a restricted passage 26 connects the bellows with the pipe 23, the pressure of air in this pipe being generally greater than that of the exhaust gases. Should the exhaust gas pressure, tend to exceed the scavenging pressure, e.g. due to a rise in engine speed or load, or both, the valve 16 is moved to vent the chamber 13 and allow the valve 8 to open, thereby reducing the back pressure in the conduit 1 caused by the turbine, whilst the turbine is gradually speeded up by the increased pressure in the conduit 2 to increase the scavenging air pressure and thereby cause the valve 8 to close. It is stated that if one exhaust gas conduit only is connected to the turbine, the byepass valve may open a variable amount according to temporary deviations from the balance between the exhaust gas pressure and the scavenging air pressure. It. is also stated that the byepass valve may be operated mechanically by a member in place of the control valve 16 and that the byepass valve may be operated electrically.

Abstract: 1,049,070. Spray carburetters; regulating; mixing charge. COMBUSTION & EXPLOSIVES RESEARCH Inc. Aug. 2, 1963, No. 30704/63. Heading F1B. Fuel-air mixture from a carburetter 3 flows into a turbulence chamber 5 to varporise the fuel droplets, the pressure drop between the carburetter inlet and the turbulence chamber being maintained at a predetermined value at full load to ensure that the velocity of the mixture entering chamber 5 is sufficiently great. The throttle valve 12 at the entrance to chamber 5 is controlled manually through a rod 20 connected to the outer ring gear 15 of an epicyclic gear having a sun gear 17 fixed on the throttle shaft 13 and a planet gear 16 carried by arms 18 freely pivoted on shaft 13. The arm 18 is connected to a capsule 22 subject to the pressure in chamber 5. When the turbulence chamber pressure is below a predetermined value, capsule 22 is contracted and the throttle valve position is determined by the manual control means 20. If the pressure in chamber 5 rises above the predetermined value, capsule 22 expands and moves arm 18 to override the manual control and close throttle 12 until the predetermined pressure is restored.

Title: Improvements in the manufacture of headers and manifolds
IPC: B21C37/29
Filed: 1956-10-09
Abstract: 803,037. Making pipe fittings; stamping; forging. HUET, A. Oct. 9, 1956 [Nov. 10, 1955 ; Feb. 29, 1956], No. 30747/56. Classes 83 (2) and 83 (4). In a method of forming multiple nipples i, Fig. 4, on a header pipe a, a series of hydraulically-operated punches g mounted on a common base f inside the pipe are operated simultaneously through a common pipe connection k. Alternatively the nipples are pierced in succession by a mechanically operated punch m, Fig. 6, articulated on one end of a lever a<SP>1</SP> which is pivoted between plates c, Fig. 7, inside the pipe and actuated at its other end by pressure or impact on an external rod n. In forming the first nipple the rod n is outside one end of the pipe but in forming successive nipples the plates c are moved through the pipe on a bar t, and the rod n, is inserted through one of the nipples already formed. In the first example the header is surrounded by a pair of dies b1, b2, Fig. 2, and is heated in the region at which the nipple is to be formed so that as the dies are brought together a thickening of the material occurs to reinforce this region. Recesses in the dies may also form stiffening ribs d, e, Fig. 4, on the header pipe. Openings m in the dies may be used for the insertion of tools to force the return of the hydraulic jacks after the formation of the nipples. Jets of hot gas may be passed through the openings m to obtain localized heating during the piercing operations. In the second example the pipe a, Fig. 6, is enclosed between a semi-cylindrical base p and a die having aperture shaped to the required form of the nipple r.

Title: An improved method of and means for vaporizing liquid fuels
IPC: F23D11/38
Filed: 1921-11-17
Abstract: 171,700. Bachhofer, P., and M³ller, J. Nov. 18, 1920, [Convention date]. Jet nozzles.-A nozzle of the type shown in Fig. 1, intended primarily for the injection of fuel into the cylinders of internal-combustion engines, is built so rigidly that no perceptible gap is formed between the members d during injection, the fuel being forced through microscopic pores in the contacting line. The criterion for the required degree of rigidity is the ability of the nozzle to produce atomized fuel which ignites spontaneously on injection into air compressed to fifteen atmospheres only. The core d and flange f may be hade of hardened steel, and the core d may be tapered. The Specification as open to inspection under Sect. 91 (3) (a) describes also several other nozzles adapted to vaporize the fuel by causing it to be forced through a very narrow orifice extremely short in the direction of the motion of the fuel. This result, which is attained by the nozzles above described and slight modifications thereof, is also secured by constructing the flange f on the core d instead of the outer portion g of the nozzle, and by the constructions shown in Figs. 1 (Cancelled), 11 (Cancelled), and 13 (Cancelled). A modification of the construction shown in Fig. 11 (Cancelled) is described, in which the spring-pressed member d<3> is flat-ended, and which is adapted to spray the fuel in a downward direction only. This subject-matter does not appear in the Specification as accepted.

Title: Improvements relating to buffers
IPC: F41A3/94
Filed: 1920-11-01
Abstract: 162,633. Thompson, J. T. April 28, 1920, [Convention date]. Ordnance breech mechanism. - Relates to buffers for the recoiling breech-blocks of automatic and semi-automatic firearms, and of the type having movable and fixed members with a spring, operating in an oil bath, interposed between them, and consists in providing Belleville springs as the cushioning-means. The fixed member 8, Fig. 1, is cylindrical and the movable member 9 a sliding fit thereon. The member 9 carries a piston 10 having an intermediate portion of frustro-conical form upon varying angles, interfitting with an opening 20 in the member 8 to vary its effective size during movement. The piston 10 then passes through a bushing 15 in a flanged plug 14 in the rear of the member 8 to a counter-recoil cap 11, controlled by a spring 12. The member 8 is secured by a screwed flange 13 in a receiver 7, and the member 9 has a flange 23, against which abuts one end of the recoil spring 24, and a rubber or like buffer 22 to receive the impact of the breech closure or similar member to which is fitted the front end of the recoil spring. Within the member 9 Belleville springs 26 are arranged having axial openings or spaced slots to allow the passage of oil, which is provided in sufficient amount substantially to fill the chambers when the buffer is compressed. As the buffer is compressed by the breech closure, the orifice 20 is reduced thus increasing the resistance to the passage of oil. The air resistance also increases. When the buffer is compressed, the spring 12 is in its normal position, and the orifice 20 is closed. The piston may be dispensed with, the counterrecoil cap being connected by rods to the flange 23. A passage is then provided in the lower portion of the end wall of the member 8 to connect the chambers. The movable member 56, Fig. 4, may slide on an intermediate member 55 connected by a sleeve 60 to a fixed member 52 which contains a tension counter-recoil spring 54 and a piston head 61. The conical part of the piston passes through a frustro-conical opening 59 in the sleeve 60, and its forward end passes through a spider 62 and supports the Belleville, springs 65. The space between the rear face of the member 56 and the head 61 is filled with oil or other suitable liquid.

Abstract: 518,858. Artificial resins. ALBERT PRODUCTS, Ltd. Oct. 25, 1938, No. 30857. Convention date, Oct. 30, 1937. [Class 2 (iii)] Artificial products hardenable at normal temperature are obtained by mixing at normal or moderate temperatures water-insoluble ureaformaldehyde and/or thioureaformaldehyde condensation products with phenol resols and hardening catalysts ; condensation products of formaldehyde with condensable amino compounds, e.g., dicyandiamide, or aniline, may be added. The two resins may be mixed, neutralized and heated with stirring, or one resin may be added to a solution, e.g., in alcohol, of the other, or solutions of both resins may be mixed and heated. Alkaline or acid catalysts may be added, preferably acid, e.g., hydrochloric, sulphuric or phosphoric acids or hydroxylamine-chlorhydrate. The products are suitable for coatings, adhesives, cement, packing and impregnating materials and for castings and plastic masses. In examples, (1) a waterinsoluble product obtained by weakly alkaline condensation of urea and thiourea with formaldehyde at 30-40‹C., followed by further heating with urea nitrate in alcohol, is mixed with a phenol resol, produced by condensing phenol and formaldehyde in the presence of caustic' soda, together with glycerine as softening agent and an alcoholic solution of hydrochloric acid to produce a casting resin ; (2) a resol from dioxydiphenylmethane and formaldehyde is added to an alcoholic solution of a ureaformaldehyde condensation product and, after heating to 60-70‹C. for a short time a butanol solution of sulphuric acid, together with ethyl lactate giving a solution suitable as an adhesive, e.g., for completely hardened phenolic or carbamide resins ; (3) a butanol solution of a cresol-formaldehyde resin is mixed with a spirit-benzol alcohol solution of a urea-formaldehyde condensation product triturated with pigments or dyestuffs and alcoholic hydrochloric acid added forming enamels. The Specification as open to inspection under Sect. 91 refers to urea-formaldehyde and/or thiourea-formaldehyde condensation products in general, and includes a further example in which dimethylolurea is heated with a phenolformaldehyde resin and treated with phosphoric acid. This subject matter does not appear in the Specification as accepted.
