Title: Improvements in and relating to the manufacture of photographic images
IPC: G03C8/06
Filed: 1946-09-04
Abstract: 654,630. Photographic processes. GEVAERT PHOTO-PRODUCTEN N. V. Sept. 4, 1946, No. 26569. Convention date, March 20, 1941. Addition to 614,155. [Class 98 (ii)] In the production of a silver image in a receiving surface by diffusion of the unreduced silver halide from an exposed and developed silver halide emulsion layer in contact therewith either during or after development of the emulsion layer and by simultaneous reduction of the diffused silver halide in the receiving layer in presence of substances acting as development nuclei, finely-divided heavy metals or insoluble metal salts or metalloids which neither develop or reduce the silver halide or form less soluble compounds therewith are used as development nuclei. In example 1, paper is coated with gelatin containing colloidal silver to form a receiving layer, and this is immersed in a developer containing hypo during the development of a negative print on silver chlorobromide paper. The print is then contacted with the receiving layer for 10 minutes, and on separation the receiving layer carries a positive image, which may be toned in a selenium toning bath. In example 2, paper is coated with gelatin containing hypo and barium chloride, and the procedure is similar to example 1 using a print made by reflex copying on silver chloride paper. The Specification as open to inspection under Sect. 91 comprises also a receiving support prepared by coating paper with a composition made by mixing aqueous mercuric chloride with aqueous gelatin containing sodium hydrosulphite and allowing to stand to form colloidal mercury and then mixing with further aqueous gelatin. This subject-matter does not appear in the Specification as accepted.

Abstract: 1,240,372. Loading imbricated bags. W. R. GRACE & CO. 11 Sept., 1968 [11 Sept., 1967], No. 26825/69. Divided out of 1,240,371. Heading B8C. A chain of imbricated bags are loaded sequentially by opening each bag by reducing the air pressure above the bag and directing a fluid stream into it to open it fully and loading it by means of a reciprocating tray. The bag feeding, opening and filling apparatus comprises a support table and tape pulling unit 15 to feed a continuous chain 130 of imbricated bags, e.g. 131 to a loading position which are then opened by inflation with air and filled. The chain of bags are adhered to a pair of parallel, sticky tapes which are pulled from container 143 over rollers 73, 74 over the support table 21, twisted to run over knurled rollers 63, 64 and are crimped together by gear-wheels 30, 56. These gearwheels are actuated to pull the tapes and bags when spring 51 is released on to valve 47, Fig. 2 (not shown), starting motor 43. Air blower unit 16 operates to open and inflate bag 131 through shoot 113. Inlet 111 is closed by piston-operated gate 117, in response to co-operation of cam 125 and lever 124 on movement of tray 12. Support table and tape pulling unit 15 is pivoted at 82 and actuated by cylinder 84 in response to switch 86. The article to be loaded is placed on tray 12 which is pushed into the inflated bag, shutting off the air supply in so doing. The article is pushed from the tray 12 into the bag 131, which is thereby simultaneously stripped from the tapes, releasing spring 51 to cause the tapes to pull the next bag into position as tray 12 is retracted to allow air supply to recommence. To change the size of bags or the tape, unit 15 may be pivoted by switch 86 and the tapes released by means of toggle (57, Fig. 2, not shown), so that the chain of bags and the tapes may be withdrawn and replaced in container 143 so that a new chain may be connected. In another embodiment (Figs. 8-10, not shown), the support table and tape pulling unit (215) is fixed and the tray and blower assembly (315) is pivoted manually to facilitate application of the tapes to the front face (224) of unit (215). Tray (212) is not reciprocated, blower (210) being actuated either by spring (251) or separately. In a further embodiment (Figs. 11-13, not shown), a cartridge (400) enclosing a rotatable spool (403) is clipped on to the front face of the tape pulling unit (415) and effects the pulling of the tapes and chain of bags by means of shaft (431) and couplings (401-402).

Title: Improvements in fuel supply systems for gas turbine engines
IPC: F02C9/16
Filed: 1955-09-21
Abstract: 825,530. Gas-turbine plant. HOBSON Ltd., H. M., and GREENLAND, L. S. Sept. 13, 1956 [Sept. 21, 1955], No. 26984/55. Class 110 (3). [Also in Group XXIX] An acceleration control unit for a gas-turbine fuel supply system comprises a device 33 responsive to compressor delivery pressure for controlling a fuel metering valve 4 to maintain a constant fuel/air ratio at any selected engine speed, a device sensitive to engine speed, e.g. diaphragm 47 responsive to the delivery pressure from an engine-driven fuel pump 1, which modifies the relationship between the metered fuel flow and the compressor delivery pressure, and a pressure regulating valve 3 in series with valve 4 for controlling the pressure drop across the metering valve and preventing excessive fuel delivery during engine acceleration and connected to a device, e.g. diaphragm 32, sensitive to the whole or a portion of the pressure drop across valve 4. A gear pump 2 supplies fuel on starting the engine and at the given speed is de-clutched at 19 so that pump 1 supplies fuel past the flap valve 30. Piston 38 actuating the metering valve is exposed on one side to pump pressure and on the other side by a pressure derived through a restriction 41 from the pump line but modified by the hinged leak-off valve 43 moved in response to compressor delivery pressure by capsule 32. The pressure drop across the metering valve 4 is equal to the pressure drop across the diaphragm actuated valve 5 and a restriction 45. As pump delivery pressure, and therefor engine speed, increases diaphragm 47 closes valve 5 and diaphragm 32, having one face open to pressure downstream of valve 4 and the other to upstream pressure modified by valve 5, moves to the left to open the regulating valve 3. In a modification the parts 5, 45 and 47 are dispensed with and the chamber to the left of diaphragm 32 is connected upstream of the valve 4. Compressor discharge pressure at 34 is modified by a leak-off valve, downstream of a restoration, actuated by a piston responsive to pump delivery pressure before it is applied to the capsule 33. Specifications 764,072, 802,144, 825,529 and 825,531 are referred to.

Title: Improvements in or relating to automatic electric circuit-breakers
IPC: H01H71/68
Filed: 1937-10-06
Abstract: 502,698. Electricallyreleased switches. PRENTICE, H. G., and FIELDING. J. G. Oct. 6, 1937, No. 27032. [Class 38 (v)] An automatic circuit - breaker comprises springy or spring - loaded contacts which normally complete the breaker - operating coil circuit and are adapted to be operated by an insulating and slidably mounted bar, which is retained in its normal or inoperative position against the action of spring loading by means of a catch lever which is engaged by a trip bar. The arrangement is such that when the latter is actuated on overload by either a thermal or magnetic device, it releases the catch lever and thereby allows the insulating bar to come into action to operate at least one of the contacts. The latter comprise pivoted arms 2, 3 which are normally urged by springs 4 into engagement with a fixed bridging contact 5, and located between them is a projection 6x on an insulating bar 6 which is slidable in guides 7 and urged to the left by a spring 8. A thermally or magnetically-actuated trip bar 11, on overload, moves clear of a nose 12 on a catch 10, so allowing the bar 6 to move and projection 6x to disengage contact 2 from contact 5. In the case of a thermal trip, the contact 2 can be reset by pushing back the catch 10, as by a press-button, further inward movement of the button serving to disengage contacts 3, 5 to provide manual release. The catch 10 is pivoted on an arm 13 working over an indicator scale 14 for adjusting the trip point over a given range, movement of the arm beyond this range causing the catch to move back the bar 6 so that contacts 3, 5 separate. In Fig. 3, the adjustment is modified by slidably mounting the arm-pivot 16 in a slot in a bracket 17 which carries the pivot 19 of a graduated setting-disc 18, a spiral slot 20 in which receives the pivot 16. The lower end of the catch 10 straddles the pivot 19 with enough clearance to allow the catch to rock.

Filed: 1952-10-29
Abstract: 727,172. Bundling-machines. LOWETH, J. W. Oct. 29, 1953 [Oct. 29, 1952], No. 27180/52. Class 94 (1). [Also in Group XXIV] A machine for twisting hanks of yarn comprises a rotatable and axially-movable shaft 8 provided at one end with a U-shaped hook 9 over which one end of a hank is placed by the operator, a transmission for imparting rotation to the shaft from a power source, means for coupling the transmission to the power source as a consequence of an axial movement of the shaft due to the hank being pulled outwardly by the operator and means for automatically uncoupling the transmission from the power source after the shaft has been turned through a predetermined number of revolutions. The shaft 8 carries a spur gear 14 meshing with a gear 15 rotatable on a fixed shaft 25 and located axially by a thrust bearing 29. A chain sprocket 16 also rotatable on the shaft, is driven continuously through gearing by an electric motor and carries a disc 24 faced with a layer of cork 36 which co-operates with a similar facing on the gear 15 to form a friction coupling. The facings are normally kept in light rubbing contact by a spring 31 interposed between a thrust bearing 30 and an axiallymovable collar 32, the shaft 8 being prevented from rotating by an abutment 12 on a collar 11 which engages a fixed abutment 13. The collar 32 is backed by a member carrying a bracket 34 which is coupled by a pin 41 to a lever 38 fulcrummed at 39. When the operator exerts a pull on a hank placed over the hook 9, the abutment 12 is moved clear of the abutment 13 and a collar 45 on the shaft 8 operates the lever 38 against the action of the spring 31 to increase the pressure between the facings and cause rotation of the shaft. At the same time, a cam 48 on the lever is positioned in the path of a cam 47 on the gear 15 so that after one revolution of the gear, corresponding to three of the shaft, the lever is forced back and the shaft returns to its original position under the action of the spring 31, the abutments 12, 13 re-engaging to bring the shaft to rest with the hook in a vertical position.
