Title: Improvements in and relating to photographic cameras
IPC: G03B7/06
Filed: 1960-03-28
Abstract: 947,214. Photographic cameras. VOIGTLANDER A. G. March 28, 1960 [March 28, 1959], No. 10970/60. Heading G2A. In a photographic camera, the linear law movements of an exposure time or aperture setting member are correlated with the non linear deflection characteristic of an exposure meter galvanometer pointer by a coupling comprising a coupling bar coupled at one end to the drive shaft of a pointer scanner to rotate with the shaft and engaging a slider coupled to the setting member. The pointer 6 takes up a position dependent upon the scene brightness. On actuation of the film wind on mechanism, scanner 37 moves to the position shown in Fig. 2 and the slider 46 moves to its extreme left position. When the camera release is actuated, pointer 6 is clamped by a clamping bow 27 and the pawl 57 disengaged from the detent 56. Slider 46 is moved to the right by a spring 55, the motion of the slider being communicated to a wheel 43 through a slider and slot connection 49, 50. The wheel 43 is arrested when the abutment 40 (Fig. 2) on scanner 37 meets the pointer 6 and causing a spring 38 to be extended and the tip 41 to engage the curved surface 42. The wheel 43 in turn arrests the slider 46 to set the correct aperture through coupling 63, 61. Film speed and exposure time are allowed for by filters 69, 66 moved in front of photo-cell 71 by rings 67, 65.

Title: Improvements relating to windscreens for vehicles
IPC: B32B17/10
Filed: 1931-04-14
Abstract: 370,656. Antidazzle screens for vehicles. ARMITAGE, L. R., 6A, Spring- field Parade, Palmers Green, London. April 14, 1931, No. 10986. Drawings to Specification. [Class 103 (ii).] In a non-shatterable vehicle windscreen comprising two sheets of glass with an intervening sheet of non-shatterable material, the upper portion of the material is during the manufacturing process dyed, coloured with a combination of colours, or formed with a series of parallel strips or lines, to serve as an antidazzle device, the strips or lines being formed on each side of the material and arranged in staggered relationship to provide a venetian blind effect. The strips or lines are obtained by slicing thin layers from a block of the non- shatterable material, colouring the layers, remaking the block with a series of the coloured layers over the area which is to form the antidazzle means, and then slicing the re-made block at an incline.

Title: Improvements in pneumatic web control device
IPC: B65H23/08
Filed: 1958-04-08
Abstract: 853,589. Band brakes; fluid-pressure brakes. WOOD NEWSPAPER MACHINERY CORPORATION. April 8, 1958 [Jan. 15, 1958], No. 11038/58. Class 103 (1). [Also in Group XVI] A pneumatic web-tensioning apparatus for controlling the tension of a web running from a supply roll comprises a floating roller engaged by the web, a variable-pressure control-valve actuated by the floating roller, a pressure chamber in the control valve, a reaction chamber in the control valve communicating with the pressure chamber, pressure-operated braking means in communication with the pressure chamber for braking the supply roll, and rate control means for varying the rate at which pressure is built up in the reaction chamber upon actuation of the floating roller. As shown, the tension of a web 4 is controlled by a roller 10 carried by arm 11, the arm being urged counterclockwise by a piston 12 within a cylinder supplied with air under pressure by a valve, the setting of which determines the initial web tension. The arm 11 rocks a lever 21 carrying a roller 32 through a link 20. The roller 32 engages a piston 30 slidable. inwardly of a housing 31 of a control-valve 9 against a spring 42 engaging-a diaphragm 40 secured to a tube 41. The spring 42 balances the weights of the roller 10 and arm 11 when the arm is inclined. A reaction chamber 44 is connected by a pipe 46 to a cylinder, not shown, which varies the force applied to a tension belt, not shown, engaging the periphery of a web roll. A valve 47 controls the rate of build-up of pressure, in the reaction chamber 44. Tube 41 has an exhaust valve seat 50 co-operating with a valve 51 on a stem 52 also carrying an inlet valve 53 cooperating with a seat 54, the valves being closed by a spring 55. The inlet valve supplies air under pressure from a pipe 57 via a pressurechamber 56 to a pipe 8 leading to the brake operating cylinder, not shown. A sudden increase in web tension causes the arm 21 to move clockwise thus allowing the piston 30 to move outwardly, while the tube 41 is also moved to the left by the diaphragm 40, thus opening exhaust valve 50 connected both to the brakeoperating cylinder and to atmosphere through the tube 41. Thus, the tension belt effects a reduction in braking effect and so web tension. Should the machine being supplied with web make an emergency stop, the roller 10 moves to the left, thus moving piston 30 inwardly against spring 42, thereby moving diaphragm 40 and tube 41 to the right. The inlet valve 53 opens to cause the brake-operating cylinder to increase the braking effect on the web roll. After a delay, dependent on the setting of valve 47, the pressure in reaction chamber 44 increases, thereby moving diaphragm 40 and tube 41 to the left to shut the valve 53. Specification 838,892 is referred to.

Abstract: 434,745. Making leather. TENNANT, W. J., 111, Hatton Garden, London.-(Ritter Chemical Co. ; Amsterdam, New York, U.S.A.) April 13, 1934, No. 11226. [Class 76] Skins which have been pickled in strong acid, e.g. the usual solution of sulphuric acid and common salt, are treated with a salt of a non-soap-forming non-tanning organic acid to bring the pH value of the skins to about 5À0 to 6À0 and then chrome tanned. In practice it is advantageous to add borax and common salt and /or sodium sulphate to the organic acid salt. Sodium acetate, formate or lactate may be used as the depickling agent and organic acid may be added. In the tanning stage basic chromium sulphate, with the addition of common salt or sodium sulphate, is used. According to one example skins so tanned are further treated with an agent made from sulphonated orthocresol condensed with formaldehyde, and fat liquored with sulphonated sperm and coconut oils.
