Title: Preionizer for a spark gap
IPC: H01T23/00
Filed: 1974-07-05
Abstract: 1474440 Spark gaps GENERAL ELECTRIC CO 5 July 1974 [5 July 1973] 29946/74 Headings H1X and H1D A main spark gap is ionised ready for a discharge by a preioniser comprising a condenser and a photon emitter which are connected in series between the main gap electrodes. The condenser, Figs. 1a, 1b, consists of plates 22a, 24 on opposited sides of an insulating layer 12, connected to strips 22, 28 respectively, deposited on layer 12. Strip 28 is resistive and connected to strip 20, which has a portion forming a gap 26 with plate 24. The schematic connections of the preioniser 10, connected across the electrodes 32, 34 of main spark gap 30, are shown in Fig. 2. When an overvoltage impulse arrives, it includes a high frequency component to which the condenser offers little impedance, so that the main voltage appears across resistance 28 and gap 26. Gap 26 breaks down before the main gap 30, so that photons emitted by gap 26 ionise gap 30 which is ready to conduct as soon as the voltage across it reaches the break-down voltage. It is thus assured that gap 30 will properly protect the apparatus connected thereto. The main gap and preioniser may be assembled on a disc (Figs. 3a, 3b, not shown), and the discs may be piled to form a spark gap arrestor.

Title: Improvements in or relating to planting and manure distributing machines
IPC: A01C15/18
Filed: 1927-11-09
Abstract: 303,607. Dubbeldan, P. Nov. 9, 1927. Manure distributers; planting- machines.-In potato and like planting machines in which the potatoes are fed by hand on to an endless band moving across the machine and then vertically downwards to the furrow made by a share, a large transverse hopper provided with endless-conveyer feeding-mechanism is arranged to deliver a quantity of manure or fertilizer at the same point as the potato &c., or adjacent thereto. The hopper b extends nearly across the machine and is bevelled off to clear the planting mechanism. The manure is delivered to an adjustable, shoot y near the potato shoot g by an endless chain or belt k at the bottom of the hopper h. The belt runs over rollers on shafts i, j one of which is driven from the potato feeding mechanism by interchangeable chain gearing. The driving-chain m bears against an adjustable jockey pulley or roller m<1>. The delivery from the hopper is controlled by sliding doors n, o one in front of the other. The door n has a straight bottom edge and is adjusted by means of a pivoted spring-controlled lever provided with a projection to engage one or other of several holes p<3> in a segment p<2> The door o is formed with a gap o<1> in the bottom edge and is adjustably secured by a thumb screw o<3> passing through a slot o<2>. The belt k may be of cotton balata, &c. and may be provided with upstanding spikes or projections. An inclined scraper bears on the top of the lower run of the belt and delivers manure scraped off to an outlet orifice in the hopper. A brush bears on the roller i<1> and a scraper on the roller j<1>. Spikes on the roller a<1> may engage the belt k, or a chain on the inside of the belt may mesh with sprocket wheels on the shafts i, j. Instead of the belt an endless chain may be used the links of which are provided with vertical or inclined spikes or projections. Two chains carrying lateral projections may be employed. The upper run of the belt is supported by a platform u and its edges run under inclined metal flanges v in the hopper. The bearings of the shaft j may be adjustable to tension the belt k, or a jockey roller may be provided. The shaft j is journaled in sliding plates w movable by screwing up a nut w<2>. The spout y may be dispensed with, the outlet of the hopper h then being arranged directly over the furrow above or in front of the furrow-closing discs. The belt k may be driven by interchangeable gearing from the axle b instead of from the potato feeding mechanism. The manuring apparatus may form a separate fitting for attachment to existing planters.

Patent GB-504944-A (GB)
Title: Fuzes for projectiles, particularly for anti-aircraft fire
IPC: F42C9/16
Filed: 1937-11-02
Abstract: 504,944. Projectile fuzes. CESKOSLOVENSKA ZBROJOVKA AKCIOVA SPOLECNOST, BRNO. Nov. 2, 1937, No. 30014. Convention date, Nov. 16, 1936. (Class 9 (i)] A direct-action fuze for projectiles comprises an inertia member that sets back on discharge thereby freeing members which move outwards under the action of centrifugal force so as to render the striker free to fire the detonator on impact of the projectile and means whereby the striker is caused to tire the detonator in the event of the projectile missing the target, the action of said means being regulated by control members that are subjected to air pressure caused by the passage of the projectile through the air and which are so arranged as to prevent operation of said means until such time as the centrifugal force acting on said control members exceeds the force due to the air pressure. As shown, the body 1 of the projectile is formed with a bore 2 in which is located a detonator 3 above which is arranged the striker mechanism. This mechanism is arranged in a casing 4 which is slidably mounted in a stepped portion of the bore 2 and is formed at one end with a flange 7 which serves as an abutment for one end of a spring 8, the other end of which is supported by a shoulder 9 in the bore 2. A plug 10 screwed into the casing 4 is formed with a conical seating 11 which receives balls 12 which support the striker 15, the head 16 of which abuts against the inturned shoulder 5 of the casing 4 and is thus secured against axial displacement. The enlarged middle portion 15<1> of the striker is guided in a sleeve 17 which is provided with a flange 18 formed with radial grooves 19 which locate the balls 12. The sleeve 17 is fitted within a cylindrical sleeve 20 having an inturned flange 21 and the upper end of which abuts against the internal shoulder 6 of the casing 4. This casing is supported in grooves 31 in rollers 30 slidably mounted in openings 25 formed at an inclined angle in the body 1 of the projectile. In operation, when the projectile is fired, the flange 21 is sheared and the sleeve 20 sets back freeing the sleeve 17. The balls 12 are then free to move outwards under the action of centrifugal force thus arming the striker 15, which, in the event of the projectile hitting the target, pierces the detonator 3. Should the projectile miss the target, as soon as the centrifugal force acting on the rollers 30 attains a higher value than the air resistance acting thereon and the pressure of the spring 8 loading the casing. 4, the rollers fly out of the projectile and the spring 8 urges the casing 4 and its striker mechanism towards the detonator. According to a modification, Fig. 2 (not shown), the rollers 30 are mounted in radial bores 25 and are held by pins mounted in open-ended bores extending parallel or substantially paralieJ to the axis of the projectile.

Abstract: 1,216,944. Disc brakes. DR. HERMANN E. MULLER. 13 June, 1969 [20 June, 1968], No. 30027/69. Heading F2E. In a disc brake of the kind wherein a brake calliper 4 spans the edge of a disc 2 and is arranged to be displaced parallel to the axis of the disc in relation to a brake support 1 secured to a vehicle frame, the calliper is connected to the support on both sides of the disc by resilient bracket members 5... 8 and is adapted to swing outwardly, under the effect of braking loads, from the normal position thereof partly in a direction parallel to the disc axis and partly in a direction parallel to the disc, the calliper being guided back to the normal position thereof, i.e. the position assumed by the calliper when brake loads are not applied, upon completion of a braking operation by the resilient effect of the bracket members. As shown, the spring steel members 5...8 are secured, as by welding, to the support 1 and the ends 71, 81 are retained under spring tension in holes 9, 10 in the calliper so that the latter is freely suspended, the calliper, under heavy braking loads, being applied against the wall 16 of the support. In modifications, (a) the bracket members are arranged between parts which limit or prevent lateral swing of the members or have squareprofile ends fitted into correspondingly shaped holes, and (b) the ends 72, 82 of the members are encircled by torsion springs to inhibit movement of the members in a direction transverse to the brake disc.

Abstract: 599,060. Bread slicers. ROSE, A. G., PEARSON, F. H., and ROSE BROS. (GAINSBOROUGH), Ltd. Nov. 12, 1945, No. 30139. [Class 5 (i)] A slicing mechanism comprises a pair of knife carriers each pivotally mounted at opposite ends on corresponding arms of a pair of twoarmed rocker arms for movement about axes parallel to the pivotal axes of said arms, the carriers being disposed one on each side of a plane containing the axes of the rocker arms so that they remain parallel to each other during rocking of the arms, characterised by the disposition of the knives in their carriers and the degree of rocking of the arms being such that the knives in one frame always cut in advance of the other. In the construction illustrated, the slicing knives 14 are mounted at their lower ends on projections 16 fixed to a pair of knife frames 18, 19, and at their upper ends on projections 17 slidably mounted for vertical movement in slideways 20 on the knife frames. Springs 21 hold the knives under tension. The knife frames are pivotally attached at their corners by shafts 22 to two pairs of rocker arms 23, the lower ones being attached to a rock-shaft 24 connected to a crank 31 carried by a rotatable shaft 32, while the upper ones are pivotally mounted in bearings 26 on brackets 27 on the main frame. The pivotal axes of the upper rocker arms are coincident and are parallel to and in vertical alignment with the axis of the rock-shaft. The arms of the rocker arms are of equal length to provide for parallel motion of the knife frames during rocking. The knives in each frame arc offset with respect to the knives in the other frame, all the knives being equally spaced apart and disposed in planes offset to the planes containing the pivotal axis of the knife frames so as to bring the knives of one frame into close proximity with the knives of the other, then during rocking motion of the arms 23 the knives of each frame pass into the spaces between the knives of the other frame. The disposition of the knives and the degree of oscillation of the rocker arms is such that when the rocker arms are in their maximum position of inclination, the cutting edges of the forward set of knives lie in a plane slightly in advance of the plane of the other set of knives. A quick release device for removing the frames comprises bosses 36 and bushes 38 each provided with openings 37 and 39 on the shafts 22. Spring plungers 42 housed in the bosses 36 position the bushes 38 in the open and closed position. The Provisional Specification also describes a single lower rocker arm disposed midway between the two upper rocker arms, in place of or in addition to a pair of lower rocker arms. The knife carriers may be bifurcated and pivotally attached at the extremities of the bifurcations to a pair of upper rocker arms.
