Title: Improvements in and relating to Percussion Fuses for Explosive Projectiles.
Inventor: MIDGLEY ALBERT HENRY
IPC: F42C1/06
Filed: 1916-10-06
Abstract: 125,649. Midgley, A. H., and Vandervell, C. A. Oct. 6, 1916. Projectile fuses.-Relates to percussion fuses of the kind in which the striker and percussion cap are carried by two relatively movable pellets hava safety member interposed, which member automatically moves from between the pellets during flight and remains within the fuse-holder. According to the invention, the whole of the percussion mechanism moves bodily within the fuse-holder when the shell is discharged, causing an obstacle within the holder to be removed or modified, and allowing the pellets to be slightly separated so that the safety member is free to move into an inoperative position. In the construction shown, the pellets a, b, with which a ball o coacts in known manner, are normally held at safe by balls j. When the projectile is discharged, the percussion mechanism sets back, deforming a curved washer g or the equivalent. This allows a spring f to separate the pellets slightly, so that the balls o can escape into an annular recess k in the fuse body. The fuse is thus armed. Specification 112,633 is referred to.

Title: Improvements in the production of photographic negatives and diapositives
IPC: G03F3/06
Filed: 1932-05-20
Abstract: 402,082. Photography ; colour photography. BOETTGER, A., 20, Gaiglstrasse, and KRONSCHNABL, M., 44, Nockherstrasse, both in Munich, Germany. May 20, 1932, No. 14388. Convention date, May 21, 1931. [Classes 98 (i) and 98 (ii).] In order to secure finer gradations of colour or of light and shade, without retouching, photographic negatives and diapositives are obtained by exposing a light-sensitive surface through photographic masking negatives or diapositives of the original, and following the masked exposures with unmasked exposures. Thus, for black-and-white pictures, the original is first photographed through a negative mask to record the finer shades, after which the mask is removed and a brief exposure is made without the mask, to record the high lights. For colour printing plate negatives, a panchromatic layer is successively exposed through a series of masking negatives and with appropriate filters and the unmasked exposure is also made through an appropriate filter. Thus, a first masking negative is taken through a "minus red " filter ; a second masking negative is obtained by exposure through an orange filter behind the first masking negative, followed by an unmasked exposure through a blue filter; and a third masking negative is obtained by exposure through an orange filter successively behind the first and second masking negatives followed by an unmasked exposure through the same filter. The yellow component negative is obtained by exposing a panchromatic layer through an orange filter and through the first masking negative, then through a blue filter and the third masking negative, and finally through a blue filter without a mask. For the red component negative, the exposures are made successively through the third masking negative with a blue filter, then through the second masking negative with a green filter and finally through the green filter alone ; and for the blue component negative, first, through the first masking negative and an orange filter, then through the second masking negative and the same filter, and finally through the same filter without a mask. If desired, a third exposure through the remaining masking negative, prior to the unmasked exposure, may be made, such exposure being made through the filter used for the unmasked exposure and being of longer duration. Examples of appropriate exposures are given. The invention may be extended to more than three colours, e.g. a fourth colour, black or grey. To ensure accurate location of the plates and masks, use is made of a dark slide comprising slides el, e<2>, f<1>, f<2> slidable on rails c d and connected by bars g<1>, g2, h<1>, h<2>, on which are adjustable slides l, m, n, o rebated at p to receive the plates q which are pressed against stops z on two contiguous sides, by opposed stops s urged outwardly by springs t. The spring stops s are retractable by cams v. Rubber cushions 5 secure the plates.

Title: Systems for regulating the air to fuel ratio of the mixture supplied to an internal combustion engine
Inventor: ZECHNALL R
IPC: F02M23/04
Filed: 1972-03-30
Abstract: 1386429 Regulating I C engine ROBERT BOSCH GmbH 30 March 1972 [2 April 1971] 14960/72 Heading F1B [Also in Divisions G1 and G3] The fuel/air mixture supplied to an I. C. engine is regulated in dependence upon the composition of the exhaust gases of the engine utilizing at least one gas probe, the/or at least one of the probes comprising an oxygen ion conductive solid electrolyte whose output signal is fed to an electronic control circuit via a low pass filter. In an intermittent fuel injection system, Fig. 1 and Figs. 2, 4, 5, 6, and 9 (not shown), the signal representing oxygen content regulates the duration of each energization of the injection valve, and in a carburetter system, Fig. 3 (not shown), the signal regulates the position of an auxiliary air throttle. As shown, the intermittent fuel injection system includes the oxygen sensor 21 whose output is applied to a threshold circuit 23 via the low pass filter 22, the output of the circuit 23 being fed to one input of a control multi-vibrator 30 via a limiting network 25. The multi-vibrator is triggered in synchronism with engine rotation, and its pulses energize an injection valve 28. The duration of the pulses is determined by the output of the limiting network 25 and by other parameters. In operation, the multi-vibrator is normally set to produce an air/fuel ratio slightly in excess of that desired so as to produce a higher than desired oxygen content. Thus, the circuit 23 is triggered to increase the pulse period of the multivibrator to produce an air/fuel ratio slightly less than that desired. A two step regulation is thereby achieved. In a modification, Fig. 2 (not shown), the output of the filter 22 is applied to a pair of differentiating amplifiers which operate so that one  responds to excess oxygen signals and the other to insufficient oxygen signals. One of the amplifiers operates to vary the pulse duration of the multivibrator, while the other operates to vary the pulse duration of a multiplying circuit which is operative to extend the pulses of the multi-vibrator. In an improvement of the above modification Figs. 5 and 6 (not shown), the carbon monoxide content or temperature of the exhaust gases is also utilized, and a function generator is provided to regulate air/fuel ratios for different engine operating condition, e.g no-load, intermediate load, and full load conditions. In a further modification, Fig. 9 (not shown), temperature compensation is provided by utilizing a temperature sensor in the exhaust manifold. Until the temperature reaches a pre-set value, the oxygen sensor signal is not utilized. Alternatively, the oxygen sensor may be provided with a heater.

Title: Improvements in Safety Mechanism for use with Gun Breech Mechanism having a Removable Firing-tube Holder.
IPC: F41A17/76
Filed: 1919-06-13
Abstract: 128,226. Schneider et Cie. Dec. 27, 1917, [Convention date]. Ordnance breech mechanism.-Relates to safety devices for primer locks of the kind in which the primer lock constitutes a holder for the primer and is removed after each discharge to receive a new primer. According to the invention, (1) the insertion of the primer lock is prevented by a sliding-bolt, various forms of which are described, until the breech-block has been fully screwed home, and (2) the pivoted firing-hammer is prevented from contacting with the striker until the primer lock has been secured in its recess. In the form shown in Figs. 3 and 4, the primer lock G is screwed into a central aperture in the breechblock carrier C, and the hammer J is pivoted below the carrier. A bolt I is slidably mounted in the carrier, and, when the breech is closed, its upper end can enter a recess a<3> in the breechscrew A. After discharge, the lock G is first removed; the rotation of the breech-screw then depresses the bolt I so that the latter protrudes into the primer-lock recess and prevents re-insertion of the lock until the breech has been again closed and locked. The thread g on the primer lock then pushes the bolt I upwards into the recess a<3>. The hammer J is prevented from contacting with the striker K of the primer lock until the latter is screwed home, by forming a rim on the rear face of the lock, a recess g<1> in which is presented opposite a nose on the hammer only when the lock has 'been correctly positioned. Since it is necessary to remove the primer lock by hand before the breech can be opened, the device constitutes also a hang-fire safety-device Other forms of the safety-bolt I are described which are moved into the blocking position by a spring, and in one construction, the bolt also protrudes behind the breech-mechanism lever E, to lock it, when the primer lock is in place. The bolt in this construction also locks the primer lock in position, and has to be lifted by hand before the primer lock can be unscrewed.

Abstract: 542,741. Gear-cutting; shaping. FELLOWS GEAR SHAPER CO. Oct. 8, 1940, No. 15023. Convention date, Oct. 16, 1939. [Class 83 (iii)] A shaping or like machine, particularly a gear generator of the reciprocating pinion cutter type wherein a work blank such as W, Fig. 6, has teeth generated by a reciprocating cutter C while the gear and cutter rotate in timed relation has means for effecting the relative relieving movement between the cutter and the work on the non-cutting strokes at a variable angle x to the line joining the centres c, w so that external and internal gears of different pitches, pressure angle, &c., may be cut without causing rubbing on the non-cutting strokes at the entering side m of the cutter teeth. In Fig. 1 the work W is mounted on a horizontal axis and the cutter C is mounted on a spindle 10 which is reciprocated from a main shaft 12 through a crank 13 racktoothed connecting rod 14 pinion 16 and rack sleeve 17 mounted between thrust bearings the sleeve being arranged to permit lateral spindle movement. Generating movement is imparted to the cutter by worm gearing 24 through a guide sleeve 26 co-acting with a guide on the cutter spindle. The cutter assembly is mounted in an adjustable carriage 29. A ring 30 is mounted concentrically with a bearing sleeve 31 for the hub of worm wheel 25, the sleeve being mounted to swing on trunnions 32, 33 in the ring 30. The axis N, N of the trunnions may be angularly adjusted by means of slots 35 and bolts 34 this adjustment being indicated by a scale co-acting with pointer 42. At its outer end the spindle fits in a bushing 43 having shoulders 44, Fig. 3, which engage between abutment blocks 45 which have convergent stop faces. The blocks 45 are adjustable to vary the limit of movement of the bushing 43 to determine the precise cutting position. The taper of the stop faces also allows withdrawal of the cutter spindle at different angles x within the limits of the angle of taper. The relief movements are effected by a spring 48 and are controlled by a cam 57 acting through a lever 55 and rod 50 on the bushing 43. The cam is so timed that the spindle is shifted into its cutting path before each cutting stroke and withdrawn at the end of such stroke. The bushing is guided during its movement by an angularly adjustable block 61 having at one end a plane surface 64 which is adjusted to the required angle x. The surface 64 engages the plane surface at a follower block 67 which seats in a cylindrical bearing surface secured to the bushing. A spring 70 holds the guide surfaces in contact and ensures that the bushing moves in the path determined by the setting of the block 61. The trunnion axis N, N is given the same angular setting as the block 61. Specification 500,928 is referred to.
