Abstract: 1370145 Squareness gauge J G SEATON and B C TESTER [trading as TESTON ENG] 24 Aug 1972 [22 Sept 1971] 44116/71 Heading G1M A base 1 providing a datum line 15 mounts a  column 2 which supports a sleeve 3 vertically and rotatably movable thereon, and the sleeve itself supports a pinion 22 which may be turned by a finger wheel 10 to slide a rack 9 having a carrier 7 slotted at 8 to receive a dial gauge 5. In operation the knurled screw 4 may be unlocked to allow the sleeve 3 to be rotated until a maximum reading is given by the gauge 5 on one of a pair of parallel faces 17, 18. The object being measured is then repositioned with its other face touching the  datum line 15 and another reading of 5 taken. The difference between these readings indicate the degree of squareness error between these faces and the third face 20.

Title: Photocopying apparatus
IPC: G03B17/50
Filed: 1967-09-28
Abstract: 1,201,346. Photo-copying apparatus. ITEK CORP. Sept.28, 1967 [Oct.17, 1966], No.44148/67. Heading G2A. A photo-copying apparatus includes a roller having a flattened portion which is maintained adjacent the copy sheet when the sheet feed means is deactivated, and a drive means for rotating the roller a predetermined whole number of revolutions. As shown in Fig.2, the copy material 11 is fed by a roller 24 from a cassette 22 to an exposure platen 2, where it is projection printed. After exposure, a roller 32 having a flat portion 32 is rotated a whole number of revolutions to feed the sheet 11 to a developing station 62, the feed rollers 59 of which may rotate slower than the roller 32. A photo-electric detector 33 detects the leading edge of the sheet and deactivates the roller 24 and activates a knife 23 to cut the sheet. A light source 40 radiates across the sheet path on to the detector 33, comprising two photo-cells 39, 41, shown as an inset in the Figure. The cells are mounted on a pivoted lever 36 such that the light to photo-cell 41 is blocked before that of photo-cell 39 as the leading edge of the sheet passes over the light source 40, and the difference in output from the cells activates a logic bridge which deactivates a drive motor 26. An alternative detector, Fig.3, (not shown), has a sensing member of switch projecting into the sheet path. The apparatus may include a sequence timer 64 for continuous repeating reproduction. The original is placed in a holder which is pivoted near its lower end Fig.1 (not shown), so as to be counterbalanced and so as to extend inwardly into the apparatus, when opened, to cover the lights for illuminating the original.

A prefabricated building component comprises a generally substantially planar corrugated sheet e.g. steel, asbestos or aluminium sheet, having a layer of strong insulating material e.g. foamed polyurethane, of uniform thickness greater than that of the sheet adhered to at least one major surface thereof and extending over substantially the total area of the major surface. The expression "generally planar" includes both flat and curved sheets. The insulating material may be applied to both major surfaces of the corrugated sheet. A thin layer of plastics material e.g. polyvinyl chloride, may be applied to a major surface not covered by insulating material. The corrugations of the sheet may be rectangular, trapezoidal, triangular, or undulating curvilinear cross-section. The surface of the sheet to which the insulating material is applied may be degreased, or may be coated with a primer, before application thereof. A strip along at least one edge of the major surface of the sheet to which insulating material is applied may be left bare of insulating material. The component may comprise a sheet of aluminium, first coated with a zinc chromate primer, further coated with foamed rigid polyurethane. The insulating material may be sprayed onto the major surface of the sheet by maintaining the direction of travel of the spray substantially normal to the surface. Rigid foamed polyurethane may be sprayed as a mixture of polyisocyanate and polyol together with catalytic additives, and may additionally comprise a blowing agent. The cure of the coated layer of plastics material may be completed by heat. The spraying may be performed at 10‹ to 22‹C. The jets of the spray gun may be at a distance of from 9 to 18 inches from the surface. The traverse of the spray gun may be so controlled that strips along two adjacent perpendicular edges of the surface are left bare of insulating material.
