Title: Photographic projection printing apparatus
Inventor: WOODCOCK EDWARD CECIL
IPC: G03B27/36
Filed: 1962-01-30
Abstract: 1,029,292. Projection printing apparatus. WILUAMSON MANUFACTURING CO. Ltd. Jan. 30, 1963 [Jan 30, 1962],No. 3525/62. Addition to 950, 822. Heading G2A. A projection printing apparatus has a range of magnification ratios, with automatic focusing controlled by a rotary cam coupled to means for varying the optical distance from paper to negative, the cam comprising two separate parts, providing two separate ranges of cam surfaces. In the form shown, light from a lamp 17 is reflected from a mirror 21 to pass through a condenser 22 and then the negative carrier 19. After passing through the objective 14 the light is reflected by a mirror system 15, 16 to fall on the sensitive paper on a guide 23. A carriage 12 mounting the objective and a carriage 13 mounting the mirror system are moved simultaneously to change the degree of magnification, the relationship between them for automatic adjustment of the focus being maintained by a cam arrangement. Carriage 13 is attached to a wire cable 32 looped round a drum 34. Rotation of the drum causes vertical movement of carriage 13 and hence the mirrors 15,16, and the cam arc rangement controls corresponding movement of the objective. For convenience, two separate cam parts 35a, 35b are provided, giving two separate ranges of cam surfaces, against which bear respective rollers 36a and 36b on carriage 12; cam 35a providing the higher range of magnification values, and cam 35b the lower range. The mechanism controlling the paper feed is shown in Fig.3. A connecting rod 57 is pivoted at one end 56 to a rotatable disc 52. In a slot 58 at its other end slides a pin 59 on one arm of a lever 61a. On the other arm is a roller 62, the lever being biased by a spring 63 to bring roller 62 against a cam 64. In the position shown, with pin 59 at the extreme end of slot 58, as soon as disc 52 begins to rotate, pin 59 is immediately moved by rod 57, and lever 61 tilted. The other arm 61b of lever 61 is attached to a wire cable 66 passing round a drum 67 which, through a one-way clutch 69, rotates a shaft 69; this carries a feed roller 43 which moves the paper, held firmly against it by pressure rollers 72. The paper supply roll is housed in magazine 41 and is taken up again in magazine 42. Cam 64 is shown in its lowest position, i.e. lever 61 is allowed its maximum degree of tilt anti-clockwise. In any other position of cam 64, lever 61 will be slightly clockwise of the position shown so that the pin 59 will not be right at the end of slot 58. Thus rod 57 will move a short distance before engaging pin 59 and hence actuating the paper feed. The position of cam 64 therefore controls the length of paper feed. The image area on the paper can also be varied by an adjustable masking plate 75. This is slidably moved by the arm 77a of a lever, whose other arm 77b can be tilted into various positions against the action of a spring by a rotatable cam 78. A mark ing stamp 85 and a guillotine 86 may be provided.

In a flexible mounting for a vehicle engine which is allowed to turn about its natural axis due to torque reaction, the mounting comprising parts each pivotally connected to the engine and directed tangentially to a circle centred on the natural axis, the circumference of the circle passing the pivotal connections of the parts to the engine and each part having its movements resisted by a low rate spring combined with a high rate limiting stop, a double acting hydraulic damper is connected between the engine and the vehicle frame so that engine movement about its natural axis in either direction is resisted by the damper dissipating energy and thereby preventing the accumulation of synchronous movements of large amplitude at the instants of starting and stopping. The damper may be mounted on the frame or the engine. The damper may comprise two pistons moving in opposite directions in a common cylinder interconnected by a passage having a variable orifice or a spring loaded valve. Alternatively the damper may be in the form of a straight strut extending substantially tangentially from the engine to the vehicle frame. The damper is shown applied to the flexible mountings shown in Figs. 5 and 6, 10 and 11, and 12 of Specification 483,703.

Abstract: 737,494. Valves controlled by auxiliary valves. SOC. D'INVENTIONS AERONAUTIQUES ET MECANIQUES S.I.A.M. Feb. 10, 1953 [Feb. 14, 1952], No. 3704/53. Class 135. A hydraulic system is controlled by two piston-actuated main valves, one of which serves to-interconnect the supply and motor conduits and the other, the motor and exhaust conduits, there being bleed passages past the pistons so as to connect the supply conduit with the supply port of a primary control valve, and the motor conduit with the motor port of a further primary control valve, and the two latter valves are spring-loaded in one direction and interconnected to move together so that one opens as the other shuts, except for a brief period when they are both open at the same time. In an embodiment, loose ball valves 1, 2, separated by a tappet 3, are urged to the upper position by a spring 10 and pushed to the lower position on energisation of a solenoid 13. When pushed to the lower position, valve 1 is opened against the flow of hydraulic pressure fluid from a line A to permit such fluid to act on a piston 15 and so close a valve 21 which shuts off communication between an exhaust line R and a line U leading to an hydraulically actuated apparatus. At the same time, the opening of valve 1 removes the pressure at the back of a piston 14 and so allows the supply pressure acting on the front face of the piston to force the latter to the right and open a valve 20 to permit the full supply pressure to flow to line U. Two devices similar to that shown may be combined to form one unit with the two lines U leading to a double-acting device.

Abstract: 489,975. Catamenial appliances. JOHNSON & JOHNSON (GT. BRITAIN), Ltd. (Johnson & Johnson) Feb. 8, 1937, Nos. 3762 and 19865. [Class 81 (ii)] A sanitary towel comprising a pad of absorbent material carried in a gauze wrapping which extends beyond the ends of the pad, has the gauze ends formed into attachment devices, or has attachment devices secured thereto by the application of adhesive. The ends may be turned back on themselves to form loops or may be turned back round separate loops or other anchorage devices which may be also secured to the gauze by adhesive. Alternatively the anchorage devices may be attached to the ends of the gauze, which are not turned back, in conjunction with strengthening patches. The adhesive may be latex, cellulose ester, or a phenolic resinoid and may be applied in patches, or in stripes or lines which may radiate and form strengthening means, whereby the towel takes up a concave form when in use. Loops may be applied to the end of the towel by placing suitably prepared pads 1 into trays which then travel on a continuous conveyer under various devices. The tray 3, Fig. 2, comprises a base having a plurality of slots 6 therein and side walls 7, which converge adjacent their ends 8. Beyond the portions 8 the walls are cut away to leave small projections 9 at each end, which serve to retain the loops 10 which are placed thereon previously. The towel enters the tray as a pad with the gauze wrapped round it, the ends being folded inwards upon the pad. The towel is centralized by swinging arms and then travels to a device comprising an air-pressure tube with terminal openings, which when lowered on to the pad causes the folded ends 12 to be blown open. The edges of the gauze 12<1> are folded inward by the convergent part of the tray as shown in Fig. 5. The loops 10 are then raised by pins 17, Fig. 6, operated by suitable link mechanism 18 and 20, and controlled by the cam 19. The towel is gripped by clamp 23 and the gauze ends are tucked through the loops by tucker blades 21. The ends are folded back over the loops by a mechanism similar to that which opened the loops. Coagulant is then applied to the underside of the gauze through the slots 6 by pins on upwardly swung arms and adhesive patches 34, Fig. 10, to the upper surface of the gauze, the adhesive being dried by electrically heated plates below the tray. The finished towel is ejected from the tray after being passed through a drying oven.
