Abstract: 762,199. Electrodeposition of protective coatings of titanium-cadmium alloys. MICHEL, R. Jan. 20, 1954, No. 1666/54. Class 41. Metal is rendered resistant to oxidation and stains by co-depositing on to it titanium and cadmium from an alkaline cyanide bath which contains titanium oxychloride, with or without the use of titanium anodes, the cadmium being supplied by the use of cadmium anodes and/or including in the bath cadmium oxide or a cadmium salt. The bath preferably also contains molybdic acid or a salt thereof whereby molybdenum is deposited simultaneously, or alternatively the article is rinsed after the codeposition of titanium and cadmium and is then coated with a simultaneous deposit of titanium, cadmium, and molybdenum. A final electroplated coating of chromium may be applied. After coating is completed, the metal is passivated by a nitric or chromic acid dip. Prior to plating, the metal such as iron, steel, brass or bronze is cleaned with petrol or carbon tetrachloride, pickled in hydrochloric acid, and electrolytically cleaned with sodium cyanide and soda. In the case of aluminium the pickling step is omitted.

Abstract: 1512923 Cutting pile fabric MILLIKEN RESEARCH CORP 16 Jan 1976 [20 Jan 1975] 01764/76 Heading D1S The loops of a loop pile fabric 10 having a backing 62 thereon are cut by passing the fabric 10 over a rotating cutting device 14 which cuts the loops whilst maintaining the backing 62 away from cutting blades 42. As shown in Fig. 1, the fabric 10, e.g. a tufted or bonded fabric, passes from a roll 12 under idlers 26, 28, around a guide roll 30, over the device 14, between driven feed rolls 18, 20 to a take-up roll 16. The amount of wrap of the fabric 10 around the device 14 is controlled by adjustment of idlers 32, 34 in supports 36. An air nozzle 40 blows lint or yarn from the device 14 and this is picked up by a suction conduit 46. The device 14, Fig. 2, is solid and has cutting modules 52 accommodated in grooves 50 therein, an elongate projection 54 on each module engaging in a slot 56. Each module 52, Fig. 4, comprises cutting blades 42 alternating with blade guards 44 held together on a pin 58 and moulded into a metal or plastics base 60. The guards 44 extend outwardly beyond the blades 42 so as to bear against the fabric and prevent the blades 42 from cutting the backing 62. To prevent rows or stripes appearing in the fabric during cutting, the device 14 is transversely reciprocated across the fabric 10 by a motor (64), Fig. 3 (not shown), having an eccentric (66) on the shaft (68) thereof, the eccentric (66) being connected to the shaft (70) of the device (14). In a modification, to obtain a striped pattern effect of cut and uncut pile loops, selected blades are removed in each of the longitudinal rows of blades.

[Also in Division H3] To the arrangement described in the parent Specification, in which windings W1, W2 around the core C have either a low or high inductance depending on whether the flux due to the permanent magnet M and the control electromagnet EM assist or oppose in the limbs L3 and L4, is added a further similar core C1 and associated permanent magnet M1 which may have its polarity opposed to that of the magnet M (as shown) so that when the winding W1, W2 present a low inductance, the winding W3, W4 presents a high inductance and vice versa. The polarity of the permanent magnets M, M1 may be in the same sense in which case windings W1, W2 and W3, W4 have either a high or low inductance together. The polepieces P3, P4 are made of high remanence material so that the winding W1, W2 maintains the impedance imparted to it by the control current in winding W5 after this ceases, whereas the windings W3, W4 present a high impedance since the polepieces P7, P8 are made of low remanence material.

Title: Improvements relating to shutter mechanisms
IPC: G03B7/083
Filed: 1959-01-19
Abstract: 857,410. Photo-electric control arrangements. INTERNATIONAL POLAROID CORPORATION. Jan. 19,1959 [Jan. 27, 1958], No. 1917/59. Class 40(3). Camera shutter mechanism in which the exposure time is determined by a photo-electric device has the speed of shutter movement controlled by the flow of a fluid into or out of a deformable hollow member, the rate of flow being set in accorddance with the output of the photo-electric device. In the preferred embodiment the fluid is air and the deformable hollow member a bellows. The aperture 26 is covered by pivoted shutter plate 34 having a cut-out portion 38 which moves over the aperture 26 during shutter travel. The plate 34 has an arm 42 co-operating with the activating lever 50 and a further arm 40 rigidly attached to the movable end of bellows 80. The bellows 80 may be made of resilient material or may be merely flexible. They are urged towards their extended position by a spring 87. Coupled to the interior of the bellows through opening 86 is an orifice shaped as indicated at 96. Movable freely, but immediately above the orifice, is a rotatable shutter having an opening as indicated at 110. This shutter is carried and positioned by the meter movement of a photo-electric light intensity measuring device having its light sensitive element adjacent the aperture 26. When an exposure is to be made the finger end 54 of the lever 50, which projects through the camera case, is moved upwards to the position shown in Fig. 2. While making this movement it causes shutter plate 34 to rotate clockwise expelling air from the bellows. During this movement cut-out 38 moves over aperture 26 but no exposure is made because mask 72 which is a part of lever 50 covers the aperture at this time. At or near the position shown in Fig. 2 pin 74 presses a resilient clamping plate down to hold the shutter with the opening 110 against the surface containing orifice 96, thus determining in accordance with the light falling on the photo-electric device the effective area of the aperture through which air can flow into the bellows. When the projection 66 on lever 50 clears arm 42 the shutter returns to its initial position at a rate determined by the speed at which air can flow into the bellows and the exposure is made as cut-out 38 passes over aperture 26. In a modification the pin 74 operates to free the shutter having the opening 110 at appropriate times, the shutter being clamped when the pin does not press the clamping plate out of position.
