Title: Improvements in rear-view mirrors, in particular for automotive vehicles
IPC: B60R1/08
Filed: 1950-10-27
Abstract: 680,686. Anti-dazzle devices for automobile rear view mirrors. STEHLE, P. R. J. Oct. 27, 1950 [Nov. 4, 1949], No. 26286/50. Class 103 (ii). In a rear view mirror of the type associated with a means for diverting from the driver's field of vision one fraction of the light rays likely to cause dazzling, and simultaneously filtering the remaining fraction of said dazzling rays in their path towards the mirror and from said mirror to the driver's eye, there is positioned in front of the conventional reflecting mirror at least one semi-transparent, semireflecting glass plate which is pivotally mounted in relation to said mirror so that it can occupy two positions, a daylight position in which it is parallel to the mirror and a sunset or night position in which it is inclined at an angle in relation to the mirror, the angle being so determined that the glass plate partially diverts and filters the dazzling light rays. The mirror 2, which is mounted in a casing 1, rests on a ledge 6 and is faced by a glass plate 3 which rests on the bottom 5 of the casing and is free to be pivoted about the upper edge 4 of the frame 12 by a pivoted cam 10 actuated by a trigger 11 against the action of a leaf-spring 8. For normal use the plate 3 is urged by the spring 8 against the mirror 2, both elements giving a combined un-deflected image. To limit the reflection of brilliant light the plate 3 is deflected so that a proportion of the incident light A, Fig. 4, is deflected at C, by the glass plate B, the remainder being reflected by the reflecting surface 14 of the mirror at D and filtered by the plate 3. The trigger 11 may be replaced by a mechanical or electrical remote control device and in another embodiment a plurality of deflecting plates, operated by a multiple cam device, may be used. In either embodiment the aggregate coefficient of light transmission ranges between 8 and 15 per cent and the glass plate(s) 3 may be coated with a metal such as stainless steel, aluminium or an alloy containing nickel, chromium and iron.

Title: Improvements relating to actuator mechanisms
IPC: F15B15/26
Filed: 1951-11-09
Abstract: 698,780. Door-operating appliances. SULZER FRERES SOC. ANON. Nov. 9, 1951 [Nov. 29, 1950], No. 26299/51. Class 65 (i) [Also in Groups XXVIII and XXIX] A door operating shaft 2, Fig. 1, is actuated by a lever 1 and a rod 6 connected to a fluid pressure motor 3 through an energy storing device comprising a member 9 forming the free end of the piston rod 5, a spring 7 and a member 10 capable of movement relative to the member 9 to provide for release of energy. To displace the lever 1 from the open position O to the closed position Z pressure fluid is admitted through a duct 18, a valve 19 and a duct 17 to one side of the motor piston 4 causing a pawl 13 to ride over teeth 12 of the piston rod 5 and the spring 7 to be extended to a limit determined by stops 11. In the event of a pressure leak or accidental actuation of the valve lever 20 to exhaust, the pawl allows but slight return movement of the rod 5 and member 9, and this is absorbed by the spring 7. The lever 1 thus remains in a position where it is locked against reverse movement. Reverse movement of the lever is permitted by releasing the pawl by hand (fluid being admitted to the cylinder first if necessary to take the load off the pawl) and then turning the valve to exhaust, the piston being drawn back by the door through the spring 7. In a modification a compression spring 23, Fig. 2, is located in a ratchet sleeve 22 secured to the piston 4 and has one end leaning against the piston and the other end against a collar 24 of a connecting rod 25. Spring compression is limited by abutment of the piston 4 against a collar 32. In this form air can be admitted to the left-hand end of the cylinder if necessary to produce the opening movement, the piston acting on the rod 25 through a stop 26.

Abstract: 1331491 Coating with metals to form recording mediums CHASE MANHATTAN CAPITAL CORP and UNITED CALIFORNIA BANK 2 June 1970 [6 June 1969] 26625/70 Heading C6F [Also in Division B2] A recording medium for permanently storing data by selective laser beam ablation of a layer of optical energy-absorbing material comprises a substrate, a uniform first layer of optical energy-absorbing material coated on the substrate, and a protective record layer of material transparent to the laser beam coated over the first layer which second layer provides for the maintenance of the integrity of the medium before, during and after laser beam ablation of the energyabsorbing material. A heat reflective layer may be formed intermediate the substrate and the layer of energy-absorbing materials. Preferably the energy-absorbing layer is a metal layer formed by sputtering on to the substrate. The transparent protective layer may also be formed by sputtering over the metal layer or adhesive bonding can be used. As shown in Fig. 1 a flexible transparent substrate 11 made of plastics, e.g. polyethylene terephthalate carries a layer 12 of metal, e.g. rhodium formed by vapourisation, sputtering or other vacuum deposition on to the surface of the substrate which has been precleaned by chemical techniques, and a protective 13 of transparent material, e.g. SiO 2  deposited on the metal layer by sputtering or vacuum deposition or Al 2 O 3 . Recording by laser beam ablation takes place through the transparent protective layer 13. In another embodiment, Fig. 2 (not shown) a metal layer consists of aluminium, platinum or rhodium and a heat-reflective layer of fused quarts or SiO 2  is interposed between the transparent substrate and the metal layer. In a further embodiment, Fig. 3 (not shown) metal layers are deposited on both surfaces of a transparent substrate and transparent protective layers thereafter coated over the metal layers. The substrate may be opaque. As shown in Figs. 4-6, a metal layer 30 is deposited on transparent substrate 31 by sputtering, and a protective layer 32 of transparent material is laminated over metal layer 30 by adhesive 33. Alternatively, the metal 30 can be sputtered on to the protective layer 32 and the substrate 31 thereafter laminated to the metal layer by adhesive bonding. Multilayered recording media may be produced by: (1) Fig. 8 (not shown) sputtering a metal layer on one side of a first and second transparent carrier, and adhesively laminating the carriers with the metal layer of one carrier adjacent the unsputtered side of the other carrier. A protective layer of transparent material is laminated over the exposed metal layer; (2) Sputtering a metal layer on one side of a first and second transparent carrier, and adhesively bonding an intermediate carrier to the respective sputtered metal layers on the first and second carriers, Fig. 7 (not shown). The recording media can be formed into a tape, disc or a strip for wrapping around the periphery of a drum.
