Title: Improvements in or relating to thin-film electronic circuit assemblies
IPC: H05K1/18
Filed: 1969-05-30
Abstract: 1,246,057. Thin film circuits. SIEMENS A.G. 30 May, 1969 [31 May, 1968 (2); 12 Sept., 1968; 18 Nov., 1968], No. 27388/69. Heading H1R. In a thin-film circuit assembly, the circuit is mounted on a flexible, insulating foil substrate of a polyimide, and is encapsulated in a protective layer, e.g. of varnish, or a housing. The assembly is manufactured by passing a continuous strip of the foil substrate through various stages involving spraying or vacuum deposition of resistive and conductive layers, and photographic and etching techniques to provide the desired resistor, conductor and contact area patterns. The contact areas may be tinned. In one embodiment, Figs. 1 and 2 (not shown), the assembly, which has contact areas in the form of strips (2) extending to an edge of the foil, is mounted in a rectangular housing which has embedded therein a transistor (9) which makes contact with the foil circuit through holes in the foil. The strips (2) may extend outside the housing or may be contacted by pins extending through the housing. In Fig. 5 (not shown), the assembly is wound, circuit bearing face inwards, around a cylindrical base of insulating material, e.g. ceramic, silicon, epoxy resin, P.T.F.E., or polyester material, and a thermally conductive cap is slid over the base to hold the circuit in place with the contact areas engaging contacts on the base. The circuit may be encapsulated in a protective varnish, Fig. 3 (not shown), and mounted on a printed circuit board, Fig. 4 (not shown).

Title: Improvements in automatic clutches
IPC: F16D43/10
Filed: 1946-09-12
Abstract: 616,767. Centrifugal clutches. KIRKPATRICK, H. G. Sept. 12, 1946, No. 27465. Convention date, Oct. 25, 1945. [Class 80 (ii)] In a centrifugal clutch, balls 19 housed in segmental carriers 17 are disposed between a pressure plate 21 and a spring diaphragm 15 carried by a drum 13 secured to a flywheel 11. Driving shaft 10 is bolted to the flywheel 11 and driven shaft 25 having' clutch plate 24 slidingly splined thereto is rotatably supported at its end by a ball bearing 126 mounted on the flywheel 11. Compression springs 23 are positioned between the pressure plate 21 and flywheel 11. Carriers 17 are connected by springs 20. On rotation of driving shaft 10, the carriers 17 are subjected to centrifugal force which at a predetermined speed is sufficient to overcome the combined effect of springs 20, 23 and diaphragm 15. Consequently the balls 19 ride up the ramp surface 15B and cause pressure plate 21 to move laterally and engage the clutch. When the speed of the' driving shaft falls below a predetermined value, the springs 20, 23 and diaphragm 15 cause disengagement of the clutch. The clutch is particularly applicable to motor vehicles.
Patent GB-189940-A (GB)
Title: Improvements in or relating to roundabouts or the like
IPC: A63G1/28
Filed: 1921-10-17
Abstract: 189,940. Cramp, R. Oct. 17, 1921. Roundabouts.-A roundabout comprises passenger cars attached to a wheel suspended by flexible cables from a drum mounted upon a central pillar, and means whereby the cables are wound upon and unwound from the drum so as to impart to the wheel an upward and downward spiral motion on the pillar. Fig. 1 shows the drum 2 mounted freely upon the pillar 1 and secured to the shaft 3, which is oscillated by an arm 16, Figs. 3 and 5, the arm being actuated by hydraulic mechanism. In use, the attendant operates the valveplunger 23 through the hand lever 22 so as to admit pressure fluid from the supply pipe 25 to the pipes 28, 31 alternately, and impress an oscillatory motion on the arm 16, a corresponding motion being transmitted to the wheel 6 through the cables 4. The vertical movement of the wheel on the pillar is limited automatically by the hub 7 contacting with the pivoted levers 20, 21 and actuating the rod 19 and the valve-plunger 23 to reverse the motion of the arm when the wheel is in its extreme positions. The wheel can be brought to rest by maintaining the arm in its mid position. In a modification, the supply of fluid to the pipes 28, 31 is controlled by two plungers actuated from a shaft which is rotated by means of a rack ,secured to the rod 19 co-operating with a toothed-wheel on the shaft. In another arrangement, the drum is secured to the pillar and the wheel is free to slide upon an hexagonal sleeve 42, Fig. 10, which is rotated through gearing 44, 46 from an electric motor 48. When the wheel is in its lowest position, the hub depresses a rod 51 and actuates a rod 19 which closes the motor switch 50. The wheel rises to its highest position, contacts with the lever 21 and depresses the rod 19 which opens the switch. The switch may reverse the motion of, as well as cut out the motor. The momentum of the wheel could be absorbed by working the motor as a dynamo. A magnetic brake may be fitted to the motor or other part of the apparatus to control the speed of descent of the wheel. In a further modification, in which the apparatus is portable, the drum is secured to the pillar 1, Fig. 13, which is rotated through gearing 58, 59 from a motor 62 until the speed of the wheel reaches an arbitrary point upon which the attendant disconnects the clutch 60, thus simultaneously raising a stop 63. The stop 65 on the wheel 58 contacts alternately with the opposite sides of the stop 63 until the shaft and the wheel are brought to rest.

Title: Photographic copying
IPC: G03B27/32
Filed: 1975-06-30
Abstract: 1512838 Photographic copying cameras OCE-VAN DER GRINTEN NV 30 June 1975 [28 June 1974] 27554/75 Heading G2A In a photographic copying camera where the magnification # and focusing are adjusted by moving lens-board 8 and a support 4 for the original, and two devices emit signals representative of the respective positions of the lens-board 8 and support 4, each device consists of a decade counter with discs each operating a ten-step switch, the driveshaft of the counter being coupled by gear transmission to the means for moving the lens-board 8 or the support 4. The camera shown has a frame 1 on which a body 2 is fixed. Body 2 has a glass plate for supporting the light-sensitive material. Lamp housings 5, 6, 7 illuminate the original. Cranks 11, 12 mounted in body 2, when rotated, move lens-board 8 and support 4 respectively in a vertical direction. As shown in Fig. 2, crank 11 is mounted on a horizontal shaft 13 which, by pulleys 14, 16 and a twisted belt 15, drives a vertical shaft 17. Belt 15 may have holes co-operating with teeth on pulleys 14, 16. Shaft 17 is connected to lens-board 8 to move it up and down; e.g. shaft 17 may be a lead-screw engaging a nut held captive in lens-board 8. Shaft 13 also drives through gears 21 a decade counter comprising cams 22, 23, 24 engaging switches 25, from which an electrical signal X is obtained, indicating the position of the lens-board with respect to the glass plate. Similarly, handle 12 drives a vertical shaft which moves the support 4 up and down, and produces an electrical signal C indicating the position of the support 4 with respect to the glass plate. The signal S is fed to a calculator (I), Fig. 3 (not shown), into which the values of the focal length of the lens 9 (F) and the length of the lens 9 (h) are set. The calculator (I) produces a signal (S), indicating the magnification, which is displayed at (26). Signal (S) is also fed to a second calculator (II) into which the values (F)  and (h) are set, and which produces a signal representing the required distance (C) from the glass plate of the support 4. The signal (C) is entered with a signal (C ) derived from the actual distance of the support 4 from the glass plate into a comparator (III). Thus, the operator first sets the lens by crank 11 until the desired magnification appears at (26). If the support 4 is not correctly positioned, one of two lamps (27), (28) will light, indicating in which direction support 4 should be moved to reach the correct position, in which a third lamp (29) will light.
