Title: Improvements in or relating to barometric fuze devices for aerial bombs, pyrotechnicdevices and the like
IPC: F42C5/02
Filed: 1943-05-31
Abstract: 586,837. Fuzes for aerial bombs, flares, &c. HEBARD, H. C., and IMBER RESEARCH, Ltd. May 31, 1943, No. 8668. [Class 9 (i)] A barometric fuze of the kind described in Specification 561,931, is provided with means whereby the mechanism may be adjusted during assembly so that, despite variations in the sensitivity of individual aneroid capsules, the identical height scales of the fuzes may be correct for each fuze. For this purpose, a lever 2 is pivoted at 3 on a slide 4 which is radially adjustable'by a screw 6, the head of which is exposed. An arm 7 of the lever rests upon a circular-wedge cam 8, Fig. 3, on a base 9 which is rotatable, together with a flange 10, relative to the fuze-casing and mechanism-container 1. The end 15 of the lever, when raised by the cam 8 and arm 7, forms an adjustable stop for the base 20 of the aneroid capsule 18 after the safety screw 13 has been withdrawn by the wind-vane 14 during descent of the bomb or the like. A height-scale is provided on the flange 10 and a pointer on the casing 1. At zero-setting the cam 8 lifts the arm 7 to horizontal position, but to calibrate the scale during assembly of the fuze, the cam 8 is turned to the other extremity, corresponding to the maximum height of operation, say 10,000. ft.; the fuze is subjected to a pressure corresponding to such height ; and the slide 4 is moved by the screw 6, thereby varying the angle of the lever 2 and arm 7 bearing upon the cam 8, until the fuze mechanism operates. The cam 8 will thereafter control the angle of the stoplever 2 correctly for any scale reading between maximum-height and zero. A further adjustment may be made during assembly, to obtain correct (horizontal) zero-setting of the arm 7, by relative axial movement between the casing 1 and the casting 23, permitted by a screw-andslot connection 21.

Title: Improvements in and relating to photographic enlarging apparatus
IPC: G03B27/36
Filed: 1940-05-15
Abstract: 541,154. Photographic enlarging apparatus. DEWEY, E. B. May 15, 1940, No. 8712. Convention date, May 23, 1939. [Class 98 (i)] A photographic enlarger is carried by a bracket or head 15 slidably adjustable on a standard 6 which is itself slidable in the head 4 of a fixed standard 1, the heads 4, 15 being in different vertical planes so that they may pass one another to allow adjustment over the whole length of the movable standard. In the form shown, the standard 6 is of H-section, each head sliding on one flange, adjustment being effected by pinions mounted in the heads and engaging racks on the standard. The heads are split and clamped in adjusted position by locking screws. The parts are counterbalanced by straps 13, 551, connected respectively to the head 4 and a spring reel 12 secured to the bottom of the standard 6, and to the top of the standard and a spring reel 54 carried by the head 15. When the standard 6 is lowered to its full extent automatic focusing is provided by means of a bell-crank lever 24 connected by a link 27 to the vertically-slidable lens-carrier 26 and carrying a roller 23 which engages one or other of two cam tracks 20, 21 on the standard, according to the focal length of the lens in use. For the purpose of changing from one track to the other, the head 15 is raised until the roller is clear of the upper ends of the tracks, when the spindle 52 to which the lever 24 is secured, may be shifted axially by knobs 51, 51<SP>1</SP>. When the standard 6 is raised for greater degrees of enlargement focusing is performed by the lens mount 50. The condenser lenses are mounted in a frame 41 sliding into the condenser housing from the front on guides 42, and the lamp 37 is carried by a vertically adjustable tube 36. In a modification, the movable standard is formed by two parallel members such as tubes or rods secured together at their ends by cross-pieces, and the fixed standard is hinged near its base so that it may be folded down for storage. The negative holder consists of hinged apertured upper and lower plates 68, 69, shown separated in Fig. 10 and with the upper plate inverted. Grooves 72, 721 of the width of the picture space prevent contact of the picture area with the holder. The edges of the film are pressed on to slides, formed by a wider groove 71 in the upper plate, by strips 73 housed in grooves in the lower plate and pressed upwardly by leaf springs.

Title: Improvements in or relating to gas turbine units
Inventor: HYETT VIVIAN ARCHIBALD
IPC: F02C7/32
Filed: 1964-03-03
Abstract: 1,034,233. Gas turbine engines; starting engines. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Feb. 8,1965 [March 3,1964], No. 8953/64. Headings FIG and F1K. The invention relates to means for driving the fuel pump of a gas turbine engine particularly during starting of the engine. The engine shown comprises compressor 1, combustion equipment 3 and turbine 7 which drives the compressor through shaft 15 which also drives the load. The engine comprises also a starter motor 23 shown as an electric motor, and a fuel pump 11 shown as a centrifugal type pump which supplies fuel to the combustion equipment 3 through line 13. The fuel pump 11 is arranged to be driven by the starter motor 23 at starting, the drive of the pump being taken over by the turbine and compressor assembly when the engine has reached a predetermined speed. The starter motor 23 is connected to a shaft 43 through a first one-way drive 45, and the shaft 43 is connected through gearing 41, 37B, intermediate shaft 33 and gearing 35, 39 to the extension 21 of the turbine and compressor shaft, the gear 37B constituting one element of a second one-way drive 37 which allows drive from shaft 43 to shaft 33 but not vice versa. The shaft 43 is also connected through the gearing 41, 37B to the gear 29 which is secured to the drive shaft 27 of the fuel pump 11. Thus at starting, the turbine and compressor assembly is rotated, also the fuel pump. The gear 35 secured to the intermediate shaft 33 is also in engagement with a gear 31B which constitutes one element of a third one-way drive 31, the second element 31 A of which is connected to the drive shaft 27 of the fuel pump 11. The gear ratios are such that the drive to the fuel pump 11 from the turbine and compressor assembly through the gearing 39, 35, 31B and one-way drive 31 occurs only when the speed of that assembly attains a certain pre-determined value. The motor 23 may also be used to accelerate the engine rapidly from idling speed, the motor then being used to drive the fuel pump, and possibly also the turbine and compressor assembly, the increased speed of the fuel pump and thus the increased flow of fuel to the combustion chamber serving to boost the rate of acceleration.

Patent GB-1138662-A (GB)
Title: Device for ejecting workpieces from presses
IPC: B30B15/32
Filed: 1967-02-24
Abstract: 1,138,662. Stamping. KABEL-UND METALLWERKE NEUMEYER G.m.b.H. 24 Feb., 1967 [26 Feb., 1966], No. 8996/67. Heading B3Q. An ejection apparatus for a crank-operated press conprises an ejector 3, means 6 for locking the ejector to a member 2 during its ejection stroke, means 10 for releasing the locking means after ejection is completed, permitting the ejector to withdraw relatively to the member 2, and means 17 for returning the ejector to its operative position in member 2 shortly before the press-ram has reached its bottom dead-centre. As applied to shaping workpieces in dies (not shown), from the bottom die of which the workpieces are removed by the ejector, release of the ejector from its operating member 2 allows the ejector to fall by gravity from the lower die, which is thus vacated more quickly for introduction of a further workpiece. Rods 1 connect the member 2 for movement with the ram so that during the upward ejection stroke a cam 10 beneath the press-table withdraws the locking slide 6 against the influence of a return spring 9. This allows the ejector to fall against a damper 5 and prevent return of the slide. Towards the end of the working stroke of the ram, a rod 13 bearing on the ejector encounters a stop 17 and returns the ejector to its extended position. A recess (not shown) in the rod allows the slide 6 to return beneath the ejector. In a modification. Fig. 2, the ejector 23 is held in its extended position by one or more levers 26 bearing at one end on the operating member 22 and at the other carrying rollers 28. At the end of an ejection stroke, the levers 26 are retracted into the ejector 23 by a cam 37, allowing the ejector to fall until the levers contact a nut 33. The ejector is re-set by a stop 36 towards the end of the working stroke of the ram.
