Abstract: 1,093,993. Power steering. DANFOSS A.S. July 7, 1966 [July 9, 1966], No. 30587/66. Heading B7H. [Also in Division F2] A valve arrangement for a vehicle steering system, Fig. 1, allows equalization of the pressures across servopiston 2 when the latter experiences impacts from the road wheels. As shown, the piston is supplied from pump 6, control device 7, hydraulic lock 8, Fig. 7, and lines 3, 4. If the piston is moved downwardly by an impact, the increased pressure in line 4 is relieved via line 14, relief valve 15 and drain lines 17, 9, part of the fluid from the relief valve 15 being admitted to the space above the piston via check valve 13 and lines 11, 3. If the piston is forced upwards, the increased pressure in line 3 is relieved via line 11, relief valve 12 and drain lines 17, 9, part of the fluid from relief valve 12 being admitted to the space below the piston via check valve 16 and lines 14, 4. The pairs of valves 12, 13 and 15, 16 are provided with common seat members 27, Fig. 6, each of the latter having an inwardly facing seat for a relief valve ball 43 and an outwardly facing seat for a check valve ball 41. - The seat members have pairs of passages (30, 31) and (32, 33) in orthogonal radial planes, each pair leading from one seat to the opposite end of the members. Plugs 40 retain the seat members in place against shoulders 39 and a common spring 45 loads the relief valve balls. The hydraulic lock valve 8 comprises, Fig. 7, a pair of check valves 53 and a piston 56, the opposite sides of which are connected to the device 7. The valves 8, 12, 13, 15 and 16 are combined in a housing 18 having internal connections indicated in Fig. 1, and ports 19-26 for connection to the other parts of the system. In normal operation, the device 7 supplies one side or the other of piston 2 via chamber 57 or 59 of valve 8, and both valves 53 are open. When the pressure in line 3 or 4 rises as the result of a shock load on piston 2, both valves 53 close to protect device 7 and pump 6 and the pressure is equalized across piston 2 as described above.

Title: Improvements in and relating to thin layers with coloured light transmission for optical or decorative purposes
IPC: G02B5/28
Filed: 1954-10-27
Abstract: Thin layers with coloured light transmission for optical or decorative purposes are made as by vacuum or cathodical deposition from the vapour phase of two different substances in the form of a finely mixed layer on a base such as glass, one of the substances being a metal compound such as fluoride or oxide or a metal convertible to such by heating in a chemically active atmosphere and the other a metal capable of imparting colour to glass melts, and heating the mixed layer as to a temperature of 300 DEG C. to produce a colloidal inclusion of the metal in the first-mentioned substance. A solvent such as water or dilute acid may be used to enhance the colloidal structure.  The heating may be effected by action of corpuscular radiations. high frequency or ultra-sonic vibrations and may be carried out during application of the mixed layer.  In Example A, gold and zinc are so vaporized on to a carrier surface and heated in an oxygen-containing atmosphere to give a purple or blue film of extinction maximum at 550 mm . and in Example B magnesium fluoride and copper are vaporized similarly with subsequent heating to give a green film. The description following the examples states that the magnesium fluoride and copper may be vaporized at 1000 DEG C. from tungsten crucibles on to a glass plate and that the subsequent heating at 300 DEG C. may be effected in an oven, and mentions zinc oxide as a metal compound, and thorium and silver as other metals for use in the invention.

Abstract: 1,176,130. Toy disc gramophones. ASAHI TOY CO. Ltd. 29 June, 1968, No. 31180/68. Heading G5R. A record player for installation in a toy comprises a chassis adapted to house a battery, and has an electric motor, a pick-up and a hinged cover; a turn-table is journalled to the hinged cover by a shaft so that a record can be fitted or detached freely when the hinged cover is open, and the motor can drive the turn-table when the cover is closed. Playback.-Figs. 1, 2 and 5 show the apparatus during playback. The turntable 16 is driven through a belt 21 engaging a pulley 23 on the shaft of a motor 22 energized by a battery 36, Fig. 2, through a switch S, Fig. 1, closed at this time. The record 19 is held on the turntable by a spring 20. The sound is reproduced mechanically by a needle 48, boss 47 (on tone arm 44), a guide arm 56 in contact with the boss 47, and a speaker 54 secured near the end of the guide arm. During the operative traverse of the needle the boss 47 has sliding contact with guide arm 56 and is pressed downwards by a leaf spring 60 bearing on the guide arm. The boss 47 protrudes through a slot 50 in the upper surface 32 of a chassis 12. End of play.-As the needle reaches the end of its operative traverse the boss 47 on the tone arm 44 pushes the movable contact 67 away from the fixed contact 68 of the switch S to stop the motor. The "cover" 15, (at the underside on Figs. 2 and 5), hinged at 14, and on which the turntable 16 alone is mounted may then be swung outwards by pulling lug 69, Fig. 3. The switch S is maintained open by spring 60 acting on boss 47 through the guide arm 56. If desired the record may now be changed. Re-starting.-The cover 15 is swung back to the closed position. The needle 48 is still in the neighbourhood of the centre of the record 19. An operating lever 66, Fig. 2, is now pressed. This acts on a projection 64, Fig. 1, forming part of a generally annular actuator 61 pivoted at 62 in bearings 63, and normally held in the Fig. 2 position by a leaf spring 65. The pressing of lever 66 pivots actuator 61, which raises guide arm 56 (against its spring 60) free of contact with the boss 47 on tone arm 44. A torsion spring 51, Figs. 1 and 5, wound around the tone arm shaft 49 and having its free end located in an aperture 45 in the tone arm, now serves to swing the tone arm outwards to the record periphery. The movable contact 67 thereupon springs back to close switch S and restart the motor. When the lever 66 is released again, spring 60 urges needle 48 on to the record through guide arm 56 and boss 47. Playing then proceeds.

Abstract: 863,204. Vehicle headlamps. BOXWELL, C. F. N. Sept. 15, 1959, No. 31342/59. Class 75(4). In a masking device for vehicle headlamps for controlling the spread of directly radiated light consisting of a cylindrical ring element mounted within the concavity of the reflector and a maskirig shutter pivoted for movement from a position in front of the lamp bulb to one in which it lies in a plane substantially parallel to the optical axis as in Specification 756,682, the shutter is carried by a spindle lying chordal to the arc of the reflector circumference and operated by a slender bar magnet rotatable about its midpoint and co-operating with the wound cones on a pair of pole pieces so that the magnet moves through 90 degrees when the polarity of the electromagnet windings is reversed. In the form shown, the shutter D, Fig. 1, is mounted on a horizontal axis A in front of the bulb B and is associated with a ring element P, the size of which is such that the shutter D can move freely through it and the position of which inside the reflector R is determined by the cone E2 representing the "escape angle" between the rear end of the filament F and the reflector opening O. The size of the shutter D is determined by the cone E3 representing the "escape angle" between the rear end of the filament F and the front edge of the ring element P. Both sides of the shutter D may be polished or the inner surface finished dead black. Similarly the whole inner surface of the ring element P may be reflecting or the lower half or a lower quadrant blackened. The shutter may be similarly cut away. Where a bulb with main and "dip" filaments is used, the ring P may be cut away obliquely so that the plane of its rearward edge inclines towards the pivotal axis of the shutter D and the ring P and shutter D are positioned with reference to the "escape angle" cones of the dip filament. The actuating mechanism for the shutter consists of a slender bar magnet 5, Fig. 10, carried on one end of the spindle 7 of the shutter disc and a fixed electromagnet 4 having two windings, the electromagnet being in circuit with a control switch so that the polarities of the windings can be reversed. Where main and "dip" filaments in a single bulb are used these are connected to a common earth and their opposite ends each to one terminal of a double pole switch connected to the source of current, the windings of the electromagnet being arranged across the two poles so that change-over of the switch reverses the direction of current through the windings.
