Title: Improvements in the manufacture and production of condensation products
Filed: 1929-12-16
Abstract: Esters are prepared by esterifying sorbitol or mixtures thereof with one or more other polyhydric alcohols containing more than three hydroxy groups, with monobasic aliphatic carboxylic acids containing at least ten carbon atoms.  The products may be polymerized, e.g. they may be heated with sulphur or agents splitting off sulphur, or they may be polymerized and/or oxidized with air or pure oxygen or substances which split off oxygen, such as hydrogen peroxide.  In examples, (1) sorbitol and linoleic acid are heated together under pressure, giving a viscous drying oil which may be used for the production of linoleum or varnishes. The oil may be thickened by blowing with air or oxygen at raised temperature in the presence or not of oxygen transferrers such as lead and/or manganese salts of the fatty or resinic acids.  (2) A viscous oil suitable as a lubricating agent or a softening agent is obtained from sorbitol and ricinoleic acid.  The consistency of the products may be altered by partial replacement of the ricinoleic acid by acids such as stearic acid or acids of crude, deresinified or bleached montan wax.  (3) A waxy product which may be hardened by heating with calcium oxide and which may be used for floor-polishing purposes preferably after dilution with paraffin wax or ceresine and turpentine, is obtained from sorbitol and bleached montan wax.  (4) A viscous drying oil is obtained from sorbitol with soya bean oil and acids of china wood oil. Specifications 306,452 and 306,453, [both in Class 2 (iii), Dyes &c.], are referred to.

Title: Camera shutter
IPC: G03B9/58
Filed: 1972-07-18
Abstract: 1349616 Camera shutters BALDA-WERKE PHOTOGRAPHISCHE GERATE UND KUNSTSTOFF R GRUTER KG 18 Aug 1972 [25 Aug 1971] 38577/72 Heading G2A A shutter comrises at least one shutter blade 12 fixed on a pivotally mounted arm 19 having an elastic region 20, 21 which latches behind a lug 22 on the armature 15 of an electromagnet 16 as long as the electromagnet is energized, so holding the shutter open. As shown, during shutter release, a slider 4 is forced downwards against a spring 5. The slider carries a tensioning lever 8, and during the release movement a lug 10 on lever 8 strikes a projection 11 on arm 19, so that arm 19 and blade 12 are pivoted anti-clockwise, against a spring 13, to uncover the exposure aperture 14. At the end of arm 19 is a pin 21 resiliently mounted thereon by means of a spring 20. During the period in which the electromagnet is energized, the armature lever 15 is held with its plate 17 against the electromagnet, so that as arm 19 pivots anti-clockwise its spring-loaded pin 21 latches behind lug 22 and so the aperture 14 remains uncovered. The armature 15 has a spring arm 23 which bears against a fixed stop, so that the armature is urged anti-clockwise. When the electromagnet is de-energized, after an interval of time determined by a photoelectric circuit, the armature is released to be pivoted anti-clockwise by spring 23, so that arm 19 and shutter blade 12 are also released to be pivoted clockwise by spring 13, hence closing the exposure aperture. When slider 4 returns to its initial position the tensioning lever 8 moves into the path of one of the cams 27 on the winding mechanism, which pivots it anti-clockwise until a pin 31 on the lever engages in a recess 32 in a transmission lever 33. When slider 4 moves downwards, lever 33 is pivoted anti-clockwise so that its end 35 engages a surface 36 of armature 15 and pivots it clockwise back into contact with the electromagnet.

A roof of substantially the configuration of a hyperbolic paraboloid is formed of two strata of panels each comprised of two layers of boards and in one stratum the panels extend longitudinally in a direction parallel to a vertical plane through two opposite roof corners and in the other stratum the panels are arranged at right angles thereto so that one stratum takes the compressive forces and the other stratum the tensile forces. The panels are constructed by forming to shape a roof of two layers of boards running parallel to the plane joining two corners and glueing the layers together. Panels are then cut from this roof or separated therefrom along lines where glue is omitted and similar panels are formed with boards running parallel to the plane joining the other corners. The panels are transported to the site, being self supporting in shape, and are superposed and assembled between and secured to girders joining the corners of the roof. The two panel layers are secured together as by railing.
