Title: Improvements in and relating to biscuit making machines
IPC: A21C11/10
Filed: 1936-02-05
Abstract: 471,739. Biscuit &c. cutting-machines. MARSDEN L., LAPIDUS, J., and MARSDEN, P. Feb. 5, 1936, No. 3419. [Class 87 (ii)] In a biscuit-making machine wherein dough f is carried between a table or support d and a combined cutter c and embosser a, the support d is positively reciprocated to and from the cutter and embosser. The embosser a may be secured on rods b attached to a relatively fixed part such as the levers g pivotally suspended in a frame h. The hollow cutter c is reciprocated about the embosser by an eccentric c<1> and the support d reciprocated by an eccentric d<1>. The eccentric c<1> may be advanced angularly with respect to the eccentric d<1> by 120‹. The arrangement is such that the support d rises and causes the dough to be embossed and the cutter to enter the dough. While the cutting is being completed, the table begins to fall away but at a slower speed, so that the descending cutter pushes the dough off the embosser, and finally, completes the cutting. A stripper bar may be provided around the cutter. The dough may be fed by a travelling web e. The feed may be intermittent, being stationary during embossing and cutting. Alternatively the feed may be continuous and the cutter, embosser and support may be moved bodily with the dough by reciprocation of the levers g by a lever j and eccentric g<1>. The eccentrics c<1>, d<1>, g<1> may be on one shaft i. which may be coaxial with the pivot for the levers g. The embosser may be reciprocated and in that case, the cutter may be stationary. The tools may be arranged in multiple with one common or a number of separate webs e. Specification 16602/02, [Class 87], is referred to.

Title: Improvements in mechanical fuzes for artillery projectiles
IPC: H01J29/10
Filed: 1939-02-06
Abstract: 508,296. Projectile fuzes. KUNZ, P. A. Feb. 6, 1939, No. 3863. Convention date, Feb. 21, 1938. [Class 9 (i)] Relates to a mechanical fuze. for artillery projectiles having timing gear driven under the action of centrifugal force by moving masses, one of which brings about ignition of the charge, the masses moving along a spiral path on a paraboloidal or approximately conical surrounding surface up to the moment of direct actuation of the igniter. According to the invention, the centrifugal masses instead of moving in a common track, each moves in its own spiral track and in such away that all are always at the same level, so that the masses form a moving system which is symmetrical to the axis of the projectile. As shown, the fuze body 1 carries the timing gear 2, the first wheel 4 of which is driven by a toothed rim 7 on a conical driving wheel 6 provided on its periphery with longitudinal grooves. The wheel 6 is itself driven by two balls 5a, 5b which are guided by the grooves in the wheel and under the action of centrifugal force run on a conical surrounding surface in the fuze body, each in its own spiral groove 12, 13 respectively and always at the same level as one another. At, its upper end, one of the spiral grooves communicates with an outward passage 8 into which the respective ball enters at the end of its movement and engages the firing pin 9 which, when it strikes the primer 10, ignites the explosive charge through the flash passage 11. The fuze is set by turning the cap 3 connected with the timing gear 2 so that the wheel 4 carries with it the rim 7, wheel 6 and the balls 5a, 5b. On discharge of the projectile, the timing gear is set in motion through the wheel 6 by the balls 5a, 5b, each of which, from the predetermined starting point, rises under the action of centrifugal force in its own spiral groove symmetrically opposite each other until one of the balls passes into the passage 8 and actuates the firing pin 9.

Title: Improvements in or relating to apparatus for supervising slip in friction drives
IPC: B65G43/04
Filed: 1953-02-11
Abstract: 726,979. Belt conveyers. SIEMENSSCHUCKERTWERKE AKT.-GES. Feb. 11, 1953 [Feb. 11, 1952], No. 3870/53. Class 78 (1). [Also in Group XXXVII] Relates to means for switching off an electric motor in the event of excessive slipping by a motor-driven conveyer belt. In one embodiment, Fig. 1 (not shown), separate tachometer generators are respectively coupled directly with the motor and with a detector roller driven by the belt, and the electromotive forces generated thereby are arranged in opposition to one another. The difference voltage is applied to an electromotive counting mechanism which disconnects the drive after recording a predetermined number of slip revolutions. As shown, tachometer generators 1 and 2 are respectively coupled to the shaft of the driving motor and to a detector roller, and each generator supplies a capacitor 6, 7, through a resistor 4, 5, which provides a given time constant for the charging operation. Connected in parallel with each capacitor is a discharge resistor 8, 9, of high positive temperature coefficient, the winding of a relay 12 being connected between points 10, 11. If the electromotive force of the generator 2 falls, the voltage across the capacitor 7 decreases at a constant rate, and, when the potential difference between the points 10, 11 reaches a sufficient value, the relay 12 responds to disconnect the driving motor or effect other appropriate control action. In another arrangement, Fig. 3 (not shown), the speed-responsive generators are of the synchronous type having permanent magnet rotors, and each generator separately supplies a synchronous motor. Both motors are coupled to a common differential gear, the output shaft of which is connected to a counting and tripping mechanism for the main drive.
