Abstract: 423,558. Buckles &c. ZIMMERMANN, V., 31, Schiesstattstrasse, Bilovec, Czecho- Slovakia. June 6, 1934, No. 16838. [Class 43] The span width of a band having both ends sewn down, e.g. to a waistcoat or sock, is adjusted by passing a loop 6 of the band or the free ends of two bands which are subsequently connected to form a loop, through a one piece buckle 5 and inserting a press-stud 12 into the root of the loop to clamp the band in desired position, the stud causing the limb of the loop to be pressed against the plain or serrated edges of the buckle slot 8. Accidental displacement of the band or the fastening members may be prevented by the engagement of the band loop with teeth 15 on the stud base or prongs on the outer edges of the buckle, a buckle of the latter type being formed with blunt protecting tongues to prevent accidental pricking. The stud may be sewn to the inner side of the band loop as shown in Fig. 4.

Title: System for speed regulating electric motors with current limitation
IPC: H02P7/34
Filed: 1954-06-11
Abstract: 740,137. Automatic speed-control systems. ATELIERS DE CONSTRUCTIONS ELECTRIQUES DE CHARLEROI. June 11, 1954 [June 11, 1953], No. 17205/54. Class 38 (4). In an electronic speed-control system with current limitation, the speed and currentresponsive signal voltages are applied to the grid control valve through parallel circuits with diode gates whereby the larger of the two signals at any time automatically blocks the other signal. The invention is described with reference to a Ward-Leonard set comprising a motor 3 and a generator 2 having its field energized through grid controlled rectifiers 5, 6 which are provided with a control valve 9 (arranged so that as its grid goes negative the motor speed increases). The speed-control signal appearing between the grid and cathode of the control valve comprises the difference between a reference voltage (er-u) derived from source 12, and the output ev from a tachometer generator 4; this signal being applied to the control valve through diode 21 and producing across resistance 15 a voltage V equal to u + ev. The voltage proportional to the motor current (obtained by any desired means) is applied to potentiometer 19 and through diode 20 to the control valve. Diode 20 remains non-conducting until vi exceed the voltage u + ev, after which diode 20 conducts to provide a current-limiting control and diode 21 is blocked to remove the speed-control signal. Modifications.-(i) The speed-responsive voltage may be derived from a potentiometer across the motor armature, and may be compensated for armature IR drop, Fig. 2 (not shown). If IR drop compensation is included the reference source er will be in series with the current-limiting signal and " backing-off " battery 23 will have to be included in the circuit; (ii) provision may be made for current control during regenerative braking by a reversely connected diode 25, Fig. 3 (not shown).

Title: Improvements in and relating to fuses for projectiles and the like
IPC: F42C1/02
Filed: 1924-07-25
Abstract: 219,700. Pantoflicek, B. July 26, 1923, [Convention date]. Projectile fuzes.-Percussion fuzes are so arranged that ignition of the fuze is effected by movement in a rearward direction, by direct impact, of one member of the fuze and movement relative to this member, under the influence of forces entirely dependent upon the movement of the fuze, of another member of the fuze, the movement of the said members being rendered possible by the movement of the other said member and the, action of the fuze being dependent upon a postive locking action or the removal of a positive locking action between the two said members during the initial stages of impact. As shown in Fig. 1, the percussion fuze has a directaction plunger 3 in conjunction with a momentum pellet 5, which normally maintains locking balls 11 in position. On impact, the pellet 5 shoots forward, releasing the balls 11; and the pLunger 3, released by the balls 11, is pushed in, driving the firing-pin 2 against the percussion cap 1. In modifications, locking balls are moved by inertia or centrifugal force, sometimes in conjunction with an initial movement of the plunger, and the movement of the balls releases the plunger or a momentum pellet carrying a percussion cap or a firing-pin. For example, in Figs. 13, balls 5 escape out of the locking position shown at the beginning of the inward movement of the plunger 3 and release a percussion cap pellet 1. This Figure also shows a spring-controlled ball 17, which prevents the passage of a flash except on impact. In other modifications, a ball or thimble causes by its momentum the securing of a firing-pin to the plunger on impact, and the firing-pin thus secured to the plunger is driven through a protecting disc covering a percussion cap. In still another modification, the inward movement of the plunger releases a percussion cap carrier, which is then driven by centrifugal force against a fixed firing-pin. The Specification as open to inspection under Sect. 91 (3) (a) also comprises direct-impactaction percussion fuzes, in which a firing-member is adapted on impact to be moved into or kept in line with the other firing-member, as now described in Specification 239,876, and fuzes in which a momentum member opens a flash passage or maintains a flash passage open on impact, as now described in Specification 239,877. This subject-matter does not appear in the Specification as accepted.
