Title: Optical System for Reproduction Machine
IPC: G03G15/30
Filed: 1966-06-27
Abstract: 1,150,462. Optical system for scanning microfiche. RANK XEROX Ltd. June 27, 1966 [June 30, 1965], No.28663/66. Headings G2A and G2H. An optical system for scanning microfiche frames has means defining a window which prevents light rays from reaching other frames when the frame being scanned has light projected therethrough and means for producing relative movement between a device holding the microfiche and the optical axis for directing image forming rays of light on to a light-sensitive surface. As applied to a xerographic machine, an image of a microfiche 40, Fig. 1, is focused through a slit aperture 18 on to the surface of a xerographic drum 20 previously electrostatically charged by corona device 21. The latent image formed is developed and transferred to a paper sheet at station 25 in known manner. The microfiche (40, Fig.2 not shown) has ninety six frames numbered in the order in which they are scanned. The microfiche is placed in a holder 48 Fig. 3 having a base 50 and a hinged cover plate (81, Fig.4 not shown) which clamps a microfiche to the base. A sheet 79 Fig. 3, of transparent material is cemented to the base. The holder 48 is placed in a carriage (100, Fig. 7 not shown) actuated as described in Specification 1,150,461. The holder is clamped between upper and lower clamping levers (221, 222) provided with clamping elements 223, 224 Fig. 11. A lamp housing 270, Fig. 1 encloses a lamp LMP 2, a bi-convex lens 271, a mirror 272, and a condenser lens 273. Light rays R converging from lens 273 are directed into the upper clamping element 223 on to the microfiche 40. The lower clamping element 224 establishes the plane of a micro-image S during scanning. An objective lens 17 is mounted within a housing having a disc 280 formed with a slot 281 in alignment with the optical axis X. During scanning, the slot 281 masks the image light rays R from the particular micro-image being scanned to limit the light rays which reach the slit 18, Fig. 1, and the drum surface 20. The elements 223, 224 are moved in the direction of the arrow, Fig. 11, during scanning.

Abstract: 261,418. Forges et Ateliers de Constructions Electriques de Jeumont. Nov. 16, 1925, [Convention date]. Fluid-pressure.-In safety brakes for winding engines of the kind in which the brake is applied by a weight and is held off by compressed air, a valve device is provided adapted to permit an initial rapid escape of the air until the pressure has fallen to a value sufficient to effect engagement of the brake, the valve then closing autoinatically and further escape of air taking place at a slower rate through a needle or other valve to give a progressive tightening of the brake. Compressed air is supplied, to a cylinder to hold off the brakes by a union b, Fig. 2, an inlet valve c, and a union a and is exhausted from the cylinder by a valve and an exhaust channel h. The valves are controlled by tappets, e, f secured to a cross-bar : i connected to an operating handle,. The exhaust chamber h, Fig. 1, communicates with the atmosphere through a rapid exhaust valve m, which may be arranged like an ordinary lever safety valve, and allows rapid fall of pressure in the brake cylinder and then closes and further exhaust takes place at reduced speed through an adjustable needle valve k.

[Also in Division B1] In a heat exchanger for condensing or evaporating refrigerant fluid, a heat exchange element 2 mounted within an outer collecting cylinder 1 comprises a plurality of horizontal tubes 2a embedded within a body 17 of porous metallic material. The body which comprises particles of spherical or cylindrical shape is located within an inverted U-shaped casing 2b closed by end covers 2c. A grid-like mesh member 18 together with a stiffener member 19 are located on top of the porous body. When operating as a condenser gaseous refrigerant enters the heat exchange element 2 through inlet pipe 4 and passes through the porous material heat exchanging with coolant flowing through the tubes 2a. The condensate leaving the heat exchange element 2 collects in the bottom of the cylinder 1 where it is sub-cooled by contact with coolant tubes 7 before finally leaving through a siphon tube 5. When operating as an evaporator (Figs. 5, 6, not shown), liquid refrigerant to be evaporated is introduced into the heat exchange element through a plurality of injection pipes (21). The tubes 7 in this case serve to superheat the refrigerant vapours in the bottom of the cylinder 1.

In a cluster of rockets suspended as described in Specification 846,246, each rocket has two circumferential screwed rings 14 and 15 (Fig. 7), abutting respectively on the slidable tail unit 3 and an abutment on the rocket body which may take the form of a boss 16 which enters into a keyway 17 in ring 14. By unscrewing the ring 15 from the ring 14 (advantageously with a torque wrench), axial play in the assembly is taken up. One ring (preferably 15) may be of plastic in order to introduce a locking effect. The rear suspension may consist of a pin 9 (Fig. 4) which enters into an arm 10 pivoting on a pin 11 in the rocket I. Pin 9 and arm 10 are locked together by a locking pin 12 which is secured in, and acts as a fulcrum for, a flap 5 which enters the nozzle of the lower rocket II. When rocket II is fired, flap 5 is urged rearward by the propellent gases unlocking arm 10 of rocket I from the pin 9 of rocket II.

Class 126 An adjustable damper in the throat of an open fireplace is so shaped and arranged that its forward surface provides a smooth upward extension of the front surface of the fireback, at least in the position giving the minimum throat area. The damper 13 is formed of refractory concrete or fireclay supported by a metal frame, and is pivotally supported by lugs on the end members of frame engaging recesses in the end walls 19 of a bearer bar 14 built into the sides of the fireplace. Abutments formed on endplates of the damper frame engage shoulders on the bearer ends 19 to limit the movement of the damper. The damper is actuated by lugs 33 on a reciprocating rod 32 engaging a stud 34 formed on one end of the damper frame and the forward position of the damper may be adjusted by a screw 42. The rear surface of the damper 13 forms a downwardly extending part of the rear wall of a smoke chamber and soot trap which is continued upwardly and rearwardly by the heat resistant concrete packing 12 behind the fire back 10. The front wall of the smoke chamber is formed by a hollow metal air-heating chamber 27 and curves smoothly upwards from a bottom semi-circular part at or slightly below the level of the rounded damper top to a rearwardly extending upper part. Air is supplied to the chamber 27 from channels 39 at the sides of the fireplace as described in Specification 785,699 [Group XIII], and the outlet 41 for heated air is hidden by a flange 46 on the cross member of a metal frame 43 surrounding the fireplace opening. The frame 43 gives the fireplace a normal appearance, though the actual height of the front opening between the bottom of the air heater 27 and the top 63 of the fret is reduced to about 9 inches. The fireplace, including the back packing 12 which is enclosed by expanded metal reinforcement, and the metal frame 43 is formed as a unit for insertion in a recess provided with a lintel 48, surround 44 and refractory hearth 11. Asbestos seals 49 are provided between the top of the unit and the lintel 48. and a front fret 55 with an air control door is integral with the frame 43. A grate frame 58 is supported by rear legs and a lip 60 overhanging the fret 55. An extension piece 63 to increase the depth of the fuel bed, is supported by pegs engaging holes in the lip 60. Cast iron linings 65 rest on the grate frame 58, which supports the grate proper. The fireback may be replaced by a boiler resting on a block, which may be removed to give access to a cleaning hole in the bottom of the boiler, which has no rear flue. A removable hood may be arranged to reflect heat back into the fireplace and close the outlet of the air heating chamber if it is desired to heat water without heating the room.
