Title: Exposure control mechanism for a photographic camera
IPC: G03B7/085
Filed: 1964-09-16
Abstract: 1,087,261. Photographic cameras. EASTMAN KODAK CO. Sept. 16, 1964 [Sept. 20, 1963], No. 37836/64. Heading G2A. In a camera, in which a pivoted, exposure meter controlled, diaphragm vane 10 has a tapered slot 14 alignable with a taking lens aperture 16, a mask member 18 is pivotable away from aperture 16, on operation of release 24, when meter 12 responds to low light values. At high light values, the downward motion of release 24 is lost to member 18 by compression of spring 28 whose resilience exerts clamping pressure between member 18 and abutment 32 on vane 10. Catch 44 retains release 24 in this position in which vane 10 cannot move. Further depression of release 24, causes projection 25 to operate shutter release 27. At low light values, the widened region of slot 14 is aligned with aperture 16, thus removing abutment 32 from the path of member 18. On depressing release 24, member 18 moves, as shown, about its pivot 22 to face aperture 16 and close contacts 46 in a flash light circuit for shutter operation. Pointer 34 moves over a bi-colour scale 40, 42 in the camera viewfinder. Reference has been directed by the Comptroller to Specification 867, 705.

Title: A process for the manufacture of vat dyestuffs from dibenzanthrone and iso-dibenzanthrone and the products produced thereby
IPC: C09B3/30
Filed: 1929-12-10
Abstract: Dibenzanthrone and isodibenzanthrone dyes are obtained by treating dibenzanthrone or isodibenzanthrone dissolved or suspended in an inorganic acid diluent possessing a dehydrating action, such as oleum or chlorsulphonic acid, with sulphur chloride S2Cl2; the products give blue shades of great brilliance and fastness, and their brilliance may be enhanced by adding relatively small quantities of boric acid during the course of the reaction.  It is probable that two S2Cl groups enter the molecule and become hydrolyzed to mercapto groups when the dyestuff is treated with water.  Examples are given.

Title: Photographic camera
IPC: G03B17/12
Filed: 1961-10-25
Abstract: 998,997. Photographic cameras. VOIGTLANDER A.G. Oct. 25, 1961 [Dec. 2,19601, No. 38274/61. Heading G2A. A photographic camera has setting means allowing for filter multiplication factors by adjustment of the diaphragm and/or shutter speed setting in which an indicator is moved into, or caused to appear in, the image field of the view-finder when a filter factor ahs been allowed for and is removed from the image field when the allowance has been cancelled. In the embodiment shown in Fig. 1 a pointer 14 is coupled by means of toothed gears 11, 9 and shaft 7 to a knob 8. This knob is also connected by gears 6, 5 to exposure setting means 3. When a filter 4 is fitted in front of the objective 2, knob 8 is rotated, and hence also the exposure setting means until the correct multiplication factor for the filter is set on scale 15, (fixed to pointer 14) relative to index 16. Simultaneously the pointer 14 is moved into the viewfinder field 13 relative to a scale 17 identical to scale 15. When no filter is fitted knob 8 is rotated until scale 15 indicates zero, the pointer 14 is no longer visible in the viewfinder field and a non toothed part of gear 6 is adjacent gear 5 which is therefore not coupled to knob 8. In alternative embodiments the pointer may be controlled by a cam or shaft 12 and it may be movable axially instead of being pivoted. In the embodiment shown in Fig. 5 the shutter speed is set by rotating ring 52 and this, through cam 53 and rod 54 pivots a lever 57 about a point 58 and the resultant movement of pulley 62 causes an exposure meter galvanometer 65 to rotate by means of a tension strip 63. The galvanometer pointer 67 moves over a scale 68 in the viewfinder field which indicates diaphragm values. The tension strip 63 connects the galvanometer pivot 64 with the cam disc 79 which controls the filter pointer 82, but during the above movement the cam is locked by pin 73 engaging one of a series of notches 72 therein. The cam 79 can be rotated manually by means of a knob (not shown) on shaft 78 to allow for a filter magnification factor, which movement is transmitted (a) to pointer 82 to move it into the viewfinder field and (b) through strip 63 to the galvanometer to vary the diaphragm reading. Ring 52 may alternatively be arranged to set the diaphragm aperture or film sensitivity.

Class 142(2) [Also in Group XXIX]  Stoppage of a loom in such a position that a cam operated valve 3 governing a weft inserting air jet 1 is open, causes a dash-pot controlled valve 6 (Group XXIX) opened by a cam 5 and upstream of the valve 3, to be closed by a spring 11, to cut off the supply of air. The low part of the cam 5, which allows the valve 6 to close, subtends at the cam axis an angle # which is the same as that subtended by the high part of the cam 2 operating the valve 3; and the cams rotate in unison with the low part of cam 5 and the high part of cam 2 in phase. The return of oil past the dash-pot piston 8 is so slow that the valve 6 does not close in the operative period of the low part of cam '5 during normal operation of the loom.

Abstract: 1278883 Cathode - ray tube displays BUNKER-RAMO CORP 11 Aug 1970 [11 Aug 1969] 38726/70 Heading H4T An arrangement for displaying graphically a succession of numerical values of a variable compares each value with a continuously counted up digital number, and when equality is recognized a signal is passed to bright-up an ordinate trace. Fig. 1 illustrates a C.R.T. dis play of the price movement of a single stock during a day's transactions, point 12 representing the previous day's closing price and the other points 14 the 18 most recent transaction prices. These 19 values are stored in digital form on a magnetic drum and read out in turn as the C.R.T. vertical raster moves from positions H6 to H24. For producing dots 14 the closing price value is used as a reference and after display (raster lines H6) is decrement ed by a "range" amount which as shown is 2 but may be changed to 4 or 8 as described below. At each of positions V3-V12 in a vertical raster stroke it is incremented and when equality is found between its value and that of a transaction the trace is brightened. If this brightening occurs at V3 or V12 the scale factor is doubled, while a large-scale factor will be decreased if no equality is signalled at V4, V5, V11 or V12, thus ensuring that the variations are displayed optimally within the top right-hand area of the Figure. As further transaction prices are entered into the system they appear at the right-hand-side of the display, shifting the' earlier dots 14 to the left, the leftmost being erased. Stock identities and pricing characters are included in the display. In modifications of the display, price ranges may be indicated by vertical bars, or the number of shares dealt with may be indicated in similar manner. Logic circuitry for all arrangements are described and illustrated schematically.

Title: Improvements in or relating to hydraulic pumps and reversible pump turbines
Inventor: HARTLAND DEREK
IPC: F03B15/00
Filed: 1962-10-15
Abstract: 1,009,900. Priming centrifugal pumps. ENGLISH ELECTRIC CO. Ltd. Oct. 14, 1963 [Oct. 15, 1962], No. 38854/62. Heading F1C. A hydraulic pump or reversible pumpturbine comprises means for injecting an emulsion of gas and water into the impeller and for varying the proportions of gas and water so as to vary the density of the emulsion during priming of the pump or of the reversible pumpturbine in operation as a pump. Pumping operation of a pump or pump-turbine is started by a procedure which is substantially the same as that described in Specification 1,006,299 but the means for controlling the power absorption comprises ports 44 through which an emulsion of air and water is introduced into the suction tube 20. During the final removal of air from the impeller 11, the power absorbed by the pump rises rapidly at a rate which tends to be difficult to control. This increase of power absorption is kept under control, however, by injecting an emulsion into the impeller 11 through the ports 44, first at a low density. The density is then gradually increased, preferably by reducing the air supply while maintaining the water supply constant, until the greater part of the impeller 11 and the top of the suction tube 20 are substantially filled with water, the air injected being exhausted to atmosphere through pipe 31. The rate of power rise during the final removal of air from the impeller 11 is thereby reduced to an acceptable value, whereby this phase may be spread over a period of 20 seconds instead of a fraction of a second. The filling of the impeller 11 may be done entirely by the injection of emulsion, without previously partly filling it with water. An emulsifying agent, such as a detergent, may be fed to the emulsifier, which may be of mechanical type or of the hydraulically energized type. The emulsifier may comprise a venturi through which water is passed, air and an emulsifying agent being fed to the throat of the venturi. The water may be supplied from the spiral casing 17 of the pump or from the pump delivery pipe. The air may be derived from an external source of compressed air or may be air which is exhausted from the impeller through pipe 31.

Abstract: 804,844. Furnace observation and access ports. BABCOCK & WILCOX Ltd. Dec. 20, 1956 [Dec.30, 1955], No. 38876/56. Class 51 (1). A circular observation port in a furnace wall comprises a throat member 20, Fig. 6, between and coaxial with convergent and divergent members 21, 19, having apex angles between 50 and 100 degrees. The members are set in a furnace wall lined with water tubes 13, Fig. 2, by welding the member 19 to tubes 13C and supporting the members 20, 21, in a framework 22 which forms the outer surface of the port structure and carries door mounting means. The port opening 10 is formed by reversely bending, at each side of the opening, a tube 13A and its neighbour 13C in planes at right-angles to each other to displace a portion of the tube 13C to the position 13D and move a portion of the tube 13A into its place. The door comprises a hinged yoke 31 having a catch-piece 45, Fig. 1, and carrying, through bolts 37, an annular windowsupporting member 34, Fig. 2, the latter having screws 38 for securing the bolts 37 passed therein. The member 34 mounts a packing-ring 44 and a window 40, the latter being held in place by a ring 41 bolted to the member. Screws 52 threaded through the yoke 31 bear on the member 34 to ensure the necessary gas seal between the latter and the frame 22. The door is securely closed by engagement between the catch 45 and a pivoted screw stud 48 carrying a knob 47 thereon. Air, from supply pipework 56, 25, 26, is passed through the port 10 from the space 23 surrounding the member 21. A valve 27 controls the air flow and, in the position shown, allows a low-pressure cooling supply to the port from the pipe 56. A block 54 carried by the valve abuts a lug 50 on the catch 45 and whilst the valve is as shown the door cannot be opened. Valve rotation to allow opening of the door causes a high-pressure air supply to flow to the port from the pipe 25 to prevent the escape of hot gases &c. when the door is opened. In a modification, a refractory-filled lance door is mounted on the yoke 31 in place of the member 34. In a rectangular port means defining a furnace wall passage of rectangular cross-section throughout its length and of acute frustopyramidal section will be used.
