Patent GB-1238887-A (GB)
IPC: G03D3/06
Filed: 1968-10-16
Abstract: 1,238,887. Photographic processing apparatus. EASTMAN KODAK CO. Oct. 16, 1968 [Oct. 20, 1967], No.49023/68. Heading G2A. Photographic film processing apparatus is provided with means for transporting film 22 through developing, fixing, washing and drying chambers thereof; with a film sensing device for detecting the presence of film in the apparatus; and with waterflow regulating means responsive to the film sensing device for supplying maximum waterflow to the washing chamber, the regulating means reducing or cutting off the waterflow a predetermined time interval after the film sensing device ceases to detect the presence of film. The film is fed into the apparatus over a table 20 having a recessed chamber 24 with apertures 26 in its top wall. As the film covers these apertures 26, the action of a suction pump 30 causes a pressure actuated switch 34 to change over to its maximum waterflow position, thereby de-energizing a time delay relay mechanism 36. This supplies power to a solenoid 40, thereby moving a valve 42 to its maximum waterflow position. When the film 22 uncovers the holes 26, the negative pressure is reduced causing the switch 34 to return to its reduced waterflow position, resupplying power to the timer 36. However the solenoid 40 is not de-energized until a capacitor associated with the timer charges up to a sufficient voltage, and the time taken for this charging is controlled by a variable time delay resistor 48 coupled to a potentiometer 50 of a film drive motor control 52. The potentiometer 50 controls the speed of film transport through the apparatus, thus the valve 42 is not moved to its reduced flow position until the film has completed its passage through the wash chamber.

Abstract: 1,250,150. Diaphragm control arrangements. PRONTOR-WERK ALFRED GAUTHIER G.m.b.H. March 24, 1970 [April 12, 1969], No.14093/70. Heading G2A. A diaphragm aperture defined by blades 2 is controlled by an electromagnet step-by-step mechanism 7 actuated by a pulse generator 8, an electric gate circuit 9 controlling the energization of the generator so that the step-by-step mechanism carries out a predetermined number of steps. On energization of the step-by-step mechanism, permanent magnet 6 pivots to swing like a pendulum, and pawl 5 mounted thereon meshes with saw-tooth like serrations 1a on diaphragm actuating ring 1 to rotate ring 1 one serration per pulse. The switching time of gate circuit 9 is controlled by an RC timing circuit consisting of capacitor C and a manually selected one of resistors R 1  -R n  housed within a remote selector 10. When a change of diaphragm valve is required, push-button 14 is depressed to close switch S 4  to thus energize an electromagnet 11. Armature 12c mounted on lever 12 is thus attracted and pins 12a, 12b lift drive pawl 5 and locking pawl 13 to allow ring 1 to rotate to a minimum position under action of spring 4. Knob 10a is then rotated to a desired setting of pointer 20a, and an appropriate resistor R 1 -R n  is bridged by contact 23. Switches S 2 , S 3  are interlocked with movement of lever 12. A tapered slot diaphragm plate may be used, and other forms of step-bystep mechanism are described.

Abstract: 1,257,688. Gripper mechanism. HEIDELBERGER DRUCKMASCHINEN A.G. 8 Dec., 1969 [27 Feb., 1969], No. 59744/69. Heading B6C. The sheer grippers 6, 7, 8 on a transfer cylinder are divided between three support bars 1, 2, 3, each of which can be adjusted radially of the cylinder independently of the other and the centre one of which can be adjusted circumferentially while the cylinder is turning. The leading edge 5 of a sheet which has suffered distortion and is to be restored to register is held by the grippers, then the bar 2 moves circumferentially while the grippers 7 relax and the sheet is held only by the grippers 6 and 8. The opening and closing of the grippers 6, 7, 8 and the movement of the bar 2 may be controlled by fixed cams, which co-operate with cam followers mounted on the cylinder, and the cam controlling the movement of the bar 2 may be adjustable, so as to allow variation of the deformation of the edge 5.

Abstract: 1,258,868. Valves. MANET INDUSTRIES (PTY.) Ltd. 12 June, 1970 [13 June, 1969], No. 28688/70. Heading F2V. [Also in Divisions F3-F4 and G2-G3] Domestic hot water is supplied to taps &c., Fig. 1, via pipe 16 from heating vessel 12 having cold water supplied from main 20 through pipe 14 and valve 18. This valve is arranged to remain closed until the level of water in expansion tank 32, connected via pipe 16 to the heating vessel 12, has fallen to a predetermined level. On expansion water from vessel 12 flows into the expansion vessel 32 by lifting the weight biased cap valve 36 and when a tap is opened water flows out through flap valve 40 in cap valve 36 which is slightly biased to closed position. When a tap is open the pressure falls in pipe 16 and hence also in connected compartment 22À1 thereby tending to draw diaphragm 24 and valve closure member 26, 28 downwards against spring 30 to open valve 18. This is prevented by the vacuum conditions in chamber 22À2 and pipe 46 which is closed off by the diaphragm at one end and at the other by float 50 in the expansion chamber. Only when the level of water in the expansion chamber falls sufficiently for float 50 to uncover the end of pipe 46 can air enter chamber 22À2 and allow the diaphragm.and closure member to descend and open valve 18. In the second embodiment Fig. 2 the expansion tank is mounted on valve 18 over the diaphragm 54 and pipes 38, 46 are omitted. When a tap is opened the pressure in pipe 16À2 and chamber 52À2 falls and the weight of water in the expansion chamber 52À1 forces the edges of dished valve 96 downwards, allowing water through apertures 92 in diaphragm 54. This valve may be replaced by annular flap valve 106, 108. Hollow column 60 and member 70À1 to which ball float 64 is pivoted are mounted on a fixed cross-support 58. When water flows from chamber 52À1 the float falls and the sleeve 62 resting on pin 72 on the float arm follows. Eventually the surface 62À1 clears balls 76 and they are pushed out by camming sleeve 78 fixed to valve stem 28 allowing the stem and diaphragm 54 to descend under the influence of spring 80, thus opening valve 18 and allowing cold water in. When the tap is closed water continues to flow until the pressure in chamber 52À2 lifts diaphragm 54 and hence stem 28, cutting off the water supply. Apertures 56 in the centre of diaphragm 54 are normally sealed by the diaphragm being pressed by spring 80 against sealing disc 102 mounted on stem 28. When the water in vessel 12 expands on heating the pressure in chamber 52À2 forces diaphragm 54 upwards and away from disc 102, allowing water to enter the expansion chamber 52À1 via apertures 56.

Abstract: 1288258 Fluid regulation UNITED KINGDOM ATOMIC ENERGY AUTHORITY 16 Oct 1970 [22 Oct 1969] 51873/69 Heading G3H [Also in Division G6] An adjustable fluid-flow impedance, which tends to suppress cavitation by the information of eddy-induced pressure drops, which is suitable for use in liquid metal flows, and which can be used to provide a gag in a fuel channel associated with the core of a nuclear reactor operating in the first neutron region and cooled by liquid sodium, comprises a series of woven wire mesh barrier elements 3 the flow cross-sectioned area of which is selectively variable. Each element comprises a backing disc 8 having formed therein a plurality of spaced flow ports 9. Each flow port accommodates a wire mesh window 10 with the windows being secured in position by being trapped between the backing plate 8 and an insert plate 11 which is welded to plate 8, the insert plate being provided with flow ports corresponding in number and relative disposition to those of the backing plate 8. A plurality of such barrier elements 3 are arranged in a spaced relationship within a flow duct (2), Fig.1 (not shown), and each has disposed upstream thereof a masking plate (12) which has flow ports matching the woven wire mesh windows in the associated element 3. The masking plates 12 are mounted on, and are rotatable by a shaft (13) which extends along the axis of the flow duct, rotation of the shaft causing the masking plates to move between positions in which the windows are totally unobstructed and substantially obstructed.

Abstract: 1288676 Valves SKODA NARODNI PODNIK 3 June 1970 [4 June 1969] 26814/70 Heading F2V A valve for controlling e.g. high or extra-high tension switches, consists of a valve body 1 with a central chamber 4 having a port 14 for connection to the switch. A valve disc 6 in the chamber has sealing surfaces 7, 8 co-operating with opposed seats 17, 18. The disc is connected to actuating pistons 9, 10 on opposite sides which are operated by air pressure admitted through control valves 24, 25. Inlet and exhaust ports 13, 15 respectively communicate with the seats. Opening of control valve 24 actuates the valve 6 into the other extreme position from that shown, and corresponds to breaking of the H.T. or E.H.T. switch. The relative areas of the pistons and if the areas enclosed by the effective seating diameters, are such that the valve 6 is biased to the position shown by the inlet pressure, and is retained in the other operated position by the fluid pressures even if both control valves 24, 25 are open. In a modification, the control valve 25 is replaced by a connection from chamber 4 through an adjustable throttle (27), Fig. 2 (not shown) into a chamber (26) communicating with the rear of piston 10.

Abstract: 1315846 Frictionally damped torsion spring units J R C MOORE 24 May 1971 [28 May 1970] 25853/70 Heading F2S A spring unit comprises two relatively rotatable members 3, 8 connected by a helical spring 11 such that relative rotation stresses the spring in torsion, the coils of the spring being in contact (with or without interleaves, Figs. 2-4, not shown) so that relative rotation of the members is resisted by the friction between the coils. The spring 11 is either prestressed, or acted upon by a tension spring inside the coil or an adjustableforce compression spring 16 to maintain the spring under axial compression with the coils in contact. The frictional resistance varies with the direction of rotation of the members 3, 8. In a vehicle suspension unit this gives a differential effect on "bump" and "recoil". The spring 11 is loaded through 30-40 degree skewed splines 10. If the angle of inclination of the splines with respect to the axis of the spring 11 is sufficiently great, the member 8 is not restored to its original position after anti-clockwise rotation, the spring force being insufficient to overcome the friction between the coils, but is locked in its deflected position. This is useful in tools, e.g. clamps. Friction interleaves may be bonded to the spring coils on one side, or may be flanged (Fig. 3) to provide frictional sliding on both sides. Fig. 4 depicts a construction for a circular-section coil spring. The interleaves may be self-lubricating. The spring 11 may be multi-start.

Abstract: 1322036 Interference microscope CARL ZEISS JENA VEB 26 Oct 1970 50771/70  Heading G2J In an interference microscope, for examining object surfaces, light from a source 1 is split at 2 into a sample beam O 1 - O 1  and a reference beam O 2  - O 2 , the sample beam is reflected to pass an objective 5 and illuminate the surface 6 to be examined, which surface 6 is located in the front focal plane of the objective 5, is reflected back along its path from the surface, through the beam splitter to a plane 7 in which is also incident the reference beam O 2 -O 2 , and a hologram, formed by the reference beam and the sample beam but reflected from a plane mirror 12 instead of the object, is located in the plane 7. Interference fringes are thus formed by the discrepancy in the surface 6 modulated wave and the image reconstructed from the hologram and these can be viewed through eypiece 9, 10. Measurement of the fringes may be effected by rotation of a parallel sides plate 11 of by movement of surface 6 in directions A. The mirror 12 is adapted to be moved into the sample beam path. If desired the objective 5 and the hologram may be replaced by two other such but having different characteristics.
