Title: A press for moulding granular materials into solid bodies
IPC: B30B15/30
Filed: 1927-12-30
Abstract: 295,178. Haddan, R., (Steatit Magnesia Akt.-Ges.). Dec. 30, 1927. Presses; delivery.-Comprises feeding-mechanism for supplying and also gripping and handling mechanism for removing pressed articles of granular material from the moulding-press, the gripping-mechanism being actuated independently of the feeding- mechanism. The moulding operation is performed by the verticallymoving plunger 21 driven by the eccentric 7 and a vertically-movable matrix 23 driven in timed relation with the plunger 21 by cam gear 36, 37, both acting in conjunction with the fixed ejecting-plunger 45. The pressing-action takes place in four stages, (1) the plunger 21 applies the initial compression while the matrix is stationary, (2) the plunger and matrix move downwards in unison to apply the main compression, (3) the plunger applies a final compression while the matrix is stationary and (4) the plunger recedes while the matrix continues to move downwards so that the moulded article is presented for delivery by the fixed plunger. The feeding-mechanism comprises a feeding-shoe 50, Fig. 5 carried by an arm feathered on the shaft 53 so that it moves with the matrix and also swings in a horizontal plane to register with the matrix opening through the medium of the cam 59 and tootned gearing 57, 54. A fixed hopper 48 charges the shoe through a flexible pipe 49. Lumps on the cam 59 vibrate the shoe when in register with the matrix opening. The gripping and handling mechanism comprises pivoted jaws 71, Fig. 8, carried by a lever 62 pivoted on the shaft 63 and operated by toothed gearing from the cam 69. The lever 62 also carries sliding wedges 75 which are advanced to release the jaws when they contact with a fixed stop 88 and are retracted to allow the spring jaws to close through the linkage 79, 82 and the cam 86.

Title: Improvements in or relating to fuses for gyratory projectiles
IPC: F42C9/18
Filed: 1932-12-16
Abstract: 392,478. Projectile fuzes. BRANDT, E. W., 101, Boulevard Murat, Paris. Dec. 16, 1932, No. 35659. Convention date, Jan. 8. Addition to 383,105. [Class 9 (i). Relates to projectile fuzes in which the striker and the primer are kept apart by balls until the centrifugal force falls during flight below a predetermined value when the fuze is fired by a spring as claimed in as the parent Specification. According to the invention the same striker and primer are so arranged that they can fire the fuze on impact if this occurs before the centrifugal force has dropped to the required value. In the form shown in the Figure, when the projectile is discharged, arming is delayed by the inertia of the various movable parts during the acceleration period. After this, a set of balls 8 bear by centrifugal force on inclined ledges 15 and wedge a ring 10a up against a spring 11. This brings holes in the ring 10a opposite a second set of balls 7, which in their turn move out to complete the arming. During flight, the striker 4 creeps up against the closing disc 19 ; and on impact the striker is driven against the primer 5. If no impact occurs, then when centrifugal has dropped sufficiently, still during flight, the spring 11 overcomes the centrifugal action of the balls against the ledge 15 and drives the ring 10a back ; and a shoulder on this ring engaging a shoulder 17 on the striker, the striker is made to fire the primer. In a modification, the balls 8, 7 are separate and the spring 11 is compressed by the recoil of the ring 10a and drives the primer against the striker when the centrifugal balls give way.

Title: Improvements in or relating to arrangements for measuring and plotting periodically varying voltages and currents
IPC: G01R13/04
Filed: 1931-12-24
Abstract: 382,464. Current, pressure, and phasedifference measurements. SIEMENS & HALSKE AKT.-GES., Siemensstadt, Berlin. Dec. 24, 1931, No. 35738. Convention date, March 21. [Class 37.] Instantaneous values and wave form of periodically varying g currents or voltages are obtained by the provision of 'two series - connected vibrating-reed switches or rectifiers, or by static contact rectifiers, the operation of the switches or rectifiers overlapping by a slight variable extent so that a measurement of this overlap gives an indication of the instantaneous current or voltage. The apparatus may be employed for regulating the peak voltage of a circuit, or for the transmission of measured magnitudes. The current or voltage to be measured is connected to terminals 1 supplying series-connected vibratory reeds 2, 3 the exciting windings 2a, 3a of which are connected in parallel through resistances 7, 8 to the secondary of a phase-shifter 9 energized at the frequency of the circuit under measurement. When the switches 2, 3 are energized in phase with the voltage or current to be measured, no indication is given by the meter 4, but if an inductance 10 is connected in one of the exciting circuits, that switch operates before the circuit of the other one is opened. The meter is then energized by a voltage, corresponding to the overlap of the switch actuation. The amount of overlap can be varied by varying the inductance 10 or by providing a second phase-shifter in place thereof. The location of the overlap may be varied by adjusting the phase-shifter 9. In a constructional form the recording drum and phase-shifter have a common drive from a spring or electric motor through a double worm gear, the motor starting switch releasing a locking tooth on the recording drum shaft, which tooth is re-engaged on the completion of a full revolution of the phaseshifter. Optical recording may be employed by the provision of mirrors arranged at right angles on the instrument shaft and rotor of the phase-shifter respectively. Specifications 353,462, [Group XXXVII], and 380,081 are referred to.
