Title: Strapping tool
IPC: B65B13/34
Filed: 1962-12-04
Abstract: 987,150. Strapping tools. STANLEY WORKS. Dec. 4, 1962 [July 18, 1962], No. 25642/64. Divided out of 987,149. Heading F2G.

Title: Firing circuit for controlled rectifiers
IPC: H02M1/08
Filed: 1965-06-17
Abstract: 1,084,934. Control system for resistance welders. SQUARE D CO. June 17, 1965 [June 22, 1964], No. 26652/65. Heading H2H. [Also in Division H3] In an arrangement in which an A.C. supply to a load 14 is controlled by a phase-controlled thyristor 13a, a train of firing pulses is applied to the thyristor rather than a single pulse. The control circuit includes a phase shifter 11a and a squarer 11b which provides a phaseshifted square wave output (ref. A, Fig. 2, not shown). Each excursion of square wavefront produces a short pulse (B or C, Fig. 2) and these initiate pulses of given duration (D, Fig. 2) during which a sequence of pulses is produced by a unijunction transistor oscillator. As shown, the control circuit includes a single-shot multivibrator circuit comprising a normally non-conducting transistor T1 and a normally conducting transistor T2. When the square waveform at A goes negative a short negative pulse is produced at B and renders transistor T1 conducting. The collector potential goes to earth and a capacitor C3 discharges through a resistor R5, during which time the transistor T2 is cut off, and the transistor T1 is maintained conducting, and the unijunction transistor oscillator T3, C4, 12, produces the train of pulses. At the end of the discharge of C3 the transistors revert to their normal state. At the commencement of the positive halfcycle of the square wave at A a capacitor C2 which had previously charged discharges through D2 and impresses a short positive pulse at C. This causes the transistor T2 to become non-conductive and the transistor T1 to conduct and similarly leads a further train of firing pulses. The inductive load 14 may be a resistance welder.

Title: Improvements in photographic objective shutters
Inventor: NOACK ROLPH
IPC: G03B9/70
Filed: 1955-09-08
Abstract: 793,567. Photographic shutters. VEB ZEISS IKON DRESDEN. Sept. 8,1955, No. 25727/55. Class 98(1) A shutter having an escapement serving both as a pretimer and a flash-contact escapement comprises a housing having a blade drive mechanism mounted therein a drive member capable of releasing the drive mechanism and having toothed segments engageable with various wheels of the escapement, a contact device in the housing for closing the flash light circuit and operable through means operatively connected with the drive member, plates pivoted within the housing and carrying the escapement wheels, and a manually operated setting slide in connection with the plates by means of which the escapement is moved to engage one wheel with one segment or another wheel with another segment so that one or more groups of wheels in the escapement can be brought alternately into driven engagement with the drive member thereby giving different delaying actions. As shown. the master member 2 is provided with two toothed members 15, 16 of different pitch which co-operate with the pinions 6 and 10 forming part of the escapement train 3-13. The escapement is pivoted at 14 and its lower plate 4 has a slot 18 engaged by a pin 17 for guiding purposes, the escapement being urged clockwise by the weak spring 20. A stronger spring 23 acts through a lever 22 on the end 21 of the upper plate 3 and tends to pivot the escapement counterclockwise. The setting slide 25 arranged above the plate 3 has a handle 26, an oblique face 28, and a lifting flank 29 and is guided by the engagement of its slot 39 with the pin 27. In the position shown, with the handle 26 aligned with mark "M", the spring-urged lever 22 rotates the escapement counter-clockwise to engage the pinion 10 with the toothed member 16, and when the released master member 2 moves in the direction of the arrow, the lug 34 strikes the nose 38 to turn the never 31 to close the contacts 32, 33 in the flash lamp circuit. The escapement in this position suitably retards further bladeopening movement of the member 2. Where the flash lamp requires no delay, the handle 26 is aligned with mark "X", whereupon the lifting flank 29 pivots the lever 31 counterclockwise so that the lug 34 slides past without causing the contacts 32, 33 to be closed, the closure of the flash lamp circuit being effected by a lever controlled directly or indirectly by the blade ring. When the escapement is to be used for delay-action purposes, the handle 26 is aligned with the mark "V/X", whereupon the oblique face 28 moves the lever 22 to an ineffective position, permitting the escapement to be rotated clockwise by the weak spring 20 to engage the pinion 6 with the toothed member 15, giving the maximum retardation. The pivot 14 may be so located that the escapement rocks out of engagement with the member 15 in setting, so that the pinion 6 need not be carried in slots. The coupling of different escapement members with the drive member may also take place axially.

The impeller comprises an upper disc 22 secured to the shaft 16 and carrying tangential blades which extend in an outwardly inclined direction to a lower ring 26. The shaft 16 is connected to an upper shaft 29 by a coupling 28, comprising similar members 31, 32, Fig. 2, clamped together and to the shafts by bolts 37, the shaft 29 extending upwardly through a gland bearing 39 and carrying a driving pulley 30. The relief valve 44 is mounted on the cover 42 of a man-hole 41 which is provided in the branch 5 adjacent the casing 1 to permit disconnection of the coupling 28 and removal of the shaft 16 and impeller 21. In operation, the butterfly valve 46 is kept closed until the whole of the air confined within the casing 1 and branch 5 is expelled through the relief valve 44, after which the valve 46 is opened to allow the water to escape from the outlet 45. The flap 48 prevents backflow when the pump is stopped.
