Filed: 1936-08-22
Abstract: 462,808. Projection screens. LASSUS ST. GENIES, A. H. J. DE. Aug. 22,1936, Nos. 23139 and 23140. Convention dates, Sept. 24, 1935 and June 13, 1936. Addition to 454,020. [Class 97 (i)] In screens according to the parent Specification, divergent lenticular elements are included in the refractive image-forming systems. In accordance with the parent Specification, the screen comprises a refractive system of lenticular elements R2 producing images of the exit pupil of the projecting objective which are imaged by a second refractive system of lenticular elements E on an unpolished screen surface 12. The image on the surface 12 is viewed through a third refractive system of lenticular elements R3. Projection may be effected from a three-dimensional object, or from images associated with a lenticular or lined screen to produce a relief effect, and the pitch of the elements R3 is a little less than the pitch of the images of the exit pupil produced on the surface 12 so as to produce a zone from which the whole picture may be seen with a relief effect. Each of the refractive systems may comprise one or more lenticular networks, and, in accordance with the present invention, the elements of any of the networks producing the images on the surface 12 may be divergent, so as to reduce the total thickness of the screen and to increase luminosity. As shown in Fig. 1, the elements R2 are divergent and such as to produce, in a plane 11, virtual images which are imaged on the surface 12 as real images substantially in contact. An opaque grid T may be provided on a face of one of the networks to prevent the impingement of rays from any element R2 on an element E with which it is not associated ; partitions between the elements may be, alternatively, provided for this purpose. Fig. 2 shows two modifications in which a network of divergent elements E is associated either with a single network comprising convergent elements R2 or with a refractive system R<1>2 comprising a network of convergent elements K and a network of divergent elements L.

Rotary mixers.-A concrete mixing- machme is provided with means whereby the raising of the charging hopper opens a supply for a measured quantity of water, effects the movement of the discharge shoot to its inoperative position, and starts a timing-mechanism which controls the period of mixing and at the end of the period effects the movement of the discharge shoot to its operative position. The water is supplied from a tank F, Fig. 1 connected by a three-way cock 2 with the main and a discharge to the constantly-rotating drum B. The cock is controlled by a link 4 operated by a rock-shaft 7 actuated by a link 12. 1'he latter is connected by a cable 17 with bell cranks 25, 26 engaged by a projection 24 on the loading skip. As the skip is raised the link 12 is operated to discharge the tank into the drum; the return of the skip to the position shown moves the link 12 in the reverse direction to open the tank to the main. Another projection 27 on the skip engages the end 28 of a rod 29 which starts the timing-device E. The operation of the rock-shaft 7 by the link 12 also effects the movement of a link 9, Fig. 3 at one end of which is a hook 73 engaging a spring-returned catch 74 operating a pivoted, spring-influenced member 62 the lower end 63 of which forms a stop for a member 49 controlling the discharge shoot. The pivoted member 62 is also operated by a sliding bar 56 through connections 54, 32 from an arm 30 actuated by the timing-device E. The hook member 73 and bar 56 have cam surfaces 75, 59 respectively so as to become inoperative at the ends of their movements. The member 49 for controlling the discharge shoot is pivoted to the main frame A, Fig. 7 and is formed with a member 47 operating the end of a pivoted member 41.

Title: Improvements in and relating to soldering metals and alloys, more particularly thosethat are difficult to solder
IPC: B23K35/00
Filed: 1946-08-08
Abstract: In coating metals or alloys particularly those difficult to coat such as aluminium or its alloys, chromium or its alloys, zirconium, or magnesium alloys, the metals &c. are coated first with a solderable metal layer by burning on with a glaze, and then with molten metal such as by dipping in molten zinc.  The solderable layer may be effected without first removing the oxide on the article, and anodized aluminium articles may then be coated.  A suspension of enamel and metal such as silver, copper, platinum, gold, or compounds thereof may be painted or sprayed on to the object and then burnt on in a manner similar to coating ceramic materials.  As an alternative a layer of enamel may be first applied and then a metallizing suspension.  Where the surface is still difficult to solder after burning on a glaze containing metals, a further metal layer free from glaze may be burnt on.  In a further form a glaze containing a metal suspension may be first applied and dried, a coating of glaze-free metal suspension then applied, and burning on then effected to fix the coating.  An aluminium plate may be sprayed with a suspension formed of 200 grams of borosilicate enamel containing 5.6 per cent of SiO2 14.8 per cent of B2O3, 71.4 per cent of PbO, 1 per cent of H2O3, 1.4 per cent of ZnO, and 2000 grams of silver or silver oxide in 1000 grams of ethylene glycol to which 50 grams of nitrocellulose is added.  After drying, a layer of silver or silver oxide free of enamel is sprayed on and after drying the second layer, heating is effected for 10 minutes at 500 DEG C.  The surface prior to coating may be pickled or sand blasted.  Sleeves or tubes of aluminium may then be used in the manufacture of coils, transformers potentiometers and other electrical parts and for kitchen or household articles.
