Abstract: 1,145,353. Photo-electric measurement. INSTITUT NATIONAL DU VERRE. March 15, 1966[March 31, 1965], No.11346/66. Heading G1A. Angularity (non-parallelism of opposed surfaces) and local distortions (e. g. lens effects due to chemical or physical heterogeneities) in sheet material 12 (e. g. a lens or windscreen) are detected and measured using a detector 24 located to receive light transmitted through the sheet and distorted thereby, but in such a position as to be on the same axis as the light beam 10 incident on the sheet. In the described embodiment, the basic optical system comprises lenses 6 and 15, focusing the image of an opaque disc-shaped mask illuminated by source 2, on to the opaque centre portion 22 of an annular aperture 21 on a screen 20 located in front of photo-cell 24. When no sheet is present in the light path, the image is superimposed exactly on the centre portion 22. The presence of a sheet having a degree of angularity causes and angular displacement (refraction) of the light and the image overlaps on to the open part of the annular aperture, cutting down the amount of light reaching detector 24. The output signal of the detector is thus representative of the presence and the degree of angularity of the sheet. In order to avoid measurement inaccuracies due to changes in light source intensity and transparency or clearness &c. of the sheet, a beam splitter 17 is provided to direct light to a second (reference) photo-cell 28, which may be connected in a Wheatstone bridge circuit with cell 24, or some other suitable circuit. A visual (e. g. meter) or audio indication may be taken, or a record (photographic, magnetic, &c. made. The record can be a continuous one taken as a particular line across the sheet is moved through the light path or as the sheet is rotated. From this record, thickness variations may be determinable. The effect of a change in light flux on the reference cell 28 due to angularity changes, is reduced by having a diffusing screen and large adjustable aperture in front of the cell. Instead of the opaque mask 8, an attenuator, or colour or polaroid filter may be used, an appropriate attenuator or filter being provided instead of the opaque portion 22 in front of cell 24. The mask may be of semicircular or quadrant form and the screen aperture 21 circular or partly obturated by a segment, Figs. 2, 3 (not shown). Such masks may be rotated instead of moving the sheet, when angularity variations in all directions are required.

Abstract: 539,910. Degreasing apparatus. FRASER & FRASER, Ltd., and HELLER, M. July 17, 1940, No. 11814. [Classes 32 and 91] [Also in Group I] A de-greasing plant is provided with a closed vessel 1 adapted to receive the degreasing liquid which may be contaminated with water or other liquid of lighter density, said vessel having a domed top 1a with a valve-controlled outlet 29 in its middle, whereby the lighter liquid, which floats on the denser de-greasing liquid, can be removed by adding further de-greasing liquid in amount sufficient to displace the lighter liquid through the outlet. The vessel 1 contains a solvent, e.g. tri- or per-chlorethylene, which is heated by a heating coil 40 and passed by means of a centrifugal pump 11 and pipe 15 to a steam-jacketed degreasing tank 3. The articles to be de-greased are placed in a basket 4 in the tank 3, which is then closed by a lid 3a ; the basket can then be rotated by a handwheel 3b Surplus solvent flows back to the tank 1 through a pipe 16, and after an interval the contents of the tank 3 are returned to the tank 1 by the pump 11. Soluble oil or the like removed from the articles in the tank 3 floats on the surface of the solvent and, under rotation of the basket 4, collects at the centre of the concave surface of the liquid, and on the return flow of liquid to the tank 1 flows down a tube 41 and is thereby removed with the liquid from the tank 3. The latter tank now contains the hot articles moistened with solvent, and solvent vapours mixed with air ; the latter are circulated by a pump 12 in a closed system including the tank 3, pipe 23, condenser 6, separator 7, pipe 25 and heater 2 to recover the solvent, which passes from the separator 7 to a storage tank 8 from which it can be led to the tank 1. When, after repeated use, it is necessary to purify the solvent in the tank 1, the soluble oil or the like floating on the surface is first removed through the outlet 29 ; the solvent is then pumped into the distilling retort 9, evaporated therein, condensed in the condenser 10 and returned to the storage tank 8.

Apparatus for wiping a windshield comprises a windshield wiper arm 1, Figs. 1 and 2, a wiper blade unit 2, a connector 4 slidably connecting the unit 2 to the arm 1, the connector and arm having co-operating means 32, 19, thereon adapted to rotate and tilt the unit 2 with respect to the arm 1 during longitudinal movement of the unit 2 relative to the arm 1. The wiper arm comprises an inner section 6 secured to a drive shaft 7, a channel section 9 pivoted at 8 to the section 6 and an outer bar-like member 10 adjustably clampable in the section 9, in known manner, by a lever 14. The member 10 has angularly disposed but coplanar straight portions 17 and 18 and a straight portion 19 which is inclined to the plane of the portions 17, 18 and offset with reference to the longitudinal axis of the portion 18. The connector 4 has a base wall 28, Fig. 4, and two upright end walls 31 having guide openings 32 to slidably receive the bar-member 10. Pivoted in an aperture in the base wall 28 is the upturned end 33 of a movement modifying arm 3 the other end of which is adjustable in a screw coupling 34 pivoted at 36 in a fitting 35 secured by a nut 38, Fig. 2, to a bearing 37 for the drive shaft 7. Clearly the relative positions of the connector and the wiper arm may be adjusted by the coupling 34. The connector 4 also has depending legs 29, between which is secured a pivot pin 30, Fig. 4, The pin 30 is journalled in a plastic bearing member 24 secured by a strap 25 in a transverse cylindrical seat in a bridge member 22 connected at its ends to a pair of yoke members carrying the wiper blade comprised of a rubber element 20 and flexible backing member 21. Referring to Fig. 10, when the wiper moves between the positions A and C over the frontal portion 39 of a "wrap-around" windshield the blade 20, 21 and connector 4 are moved outwardly along the straight portion 18 of the arm 10. On passing from the sharply curved portion C of the windshield between the frontal portion 39 and the rearwardly extending wing portion 40, the connector 4 is still moved outwardly and onto the portion 19 of the arm. The blade is thus rotated about an axis generally normal to the windshield and also tilted about its own longitudinal axis so as to be always substantially normal to the surface of the windshield.
