Title: Improvements in or relating to regulated rectifier power supply systems
Inventor: REINDL ERICH
IPC: H04M19/00
Filed: 1966-01-21
Abstract: 1,060,959. Standby supply systems. INTERNATIONAL STANDARD ELECTRIC CORPORATION. Jan. 21, 1966, No. 2891/66. Heading H2H. [Also in Division G3] A power supply arrangement for a system including terminals 14, 15 for connection to a load and terminals 12, 13 for connection to a standby battery includes a first regulator A which controls the charging voltage applied to the battery and a second regulator B which controls the voltage applied to the load, the first regulator being also controlled so that the power dissipated in the second regulator is limited to a predetermined maximum. The regulator A includes A.C. input terminals 8, 9, a series transductor 6, a transformer 3, a rectifier 4, a choke 5, output terminals 12, 13 which are connected to a standby battery and a deviation detector 7 which controls transductor 6 in dependence upon variations in the voltage applied to the battery. The regulator B is connected to the terminals 12, 13 and includes a series transistor 16 for maintaining constant the voltage at load terminals 14, 15, the transistor being controlled in known manner by a voltage detector 19. A thermistor 17 thermally bonded to transistor 16 senses the temperature of the transistor and controls the deviation detector 7 through a lead 18 to lower the voltage across terminals 12, 13 when this temperature exceeds a predetermined value. Thus when the standby battery is fully discharged, or when an overload occurs, the voltage at terminals 12, 13 is kept at a value within the regulating capacity of transistor 16 which is thereby protected against excessive dissipation.

Title: Photographic pivoted blade lens shutter with a flashbulb synchronizer
IPC: G03B9/70
Filed: 1952-02-04
Abstract: 701,870. Photographic shutters including flash lamp synchronizers. DECKEL, H., and DECKEL, F. W. Feb. 4, 1952 [April 13, 1951], No. 2897/52. Class 98(1) A photographic pivoted blade shutter incorporating a flash lamp synchronizer which after release runs through a constant distance under the control of an escapement mechanism and simultaneously operates a switch for the flash lamp as well as ultimately releasing the shutter mechanism, is characterized by a device by which the action of the escapement on the synchronizer and consequently on the duration of operation of the latter can be reduced to nearly zero. As shown, the shutter is set by rotating a master ring 12 clockwise, tensioning its driving spring 16, to the position shown in which it is latched by a clockwise urged pawl 18. Simultaneously a pin 46 on the ring engages a pawl 42 pivoted at 32 and rotates it anticlockwise so that by engagement of a nose 38 on the pawl with a projection 40 on a gear sector 24 pivoted at 26 the driving spring 28 of a retard train including a. star wheel 74 and pallet 72 is tensioned, the sector being latched when set by a pivoted pawl 74. During setting, a gear 70 and a disc 68 coaxial with a gear 64.meshing with the sector are rotated clockwise so that a lever 86 pivoted at 88 is moved anticlockwise by a cam 80 on the disc 68 so that the nose 102 of the lever is held clear of the movable contact 106 of the flashlamp circuit. On pressing the shutter release 62, the pawl 54 is moved clockwise releasing the sector 24 which rotates clockwise. Thereby the disc 68 is rotated anticlockwise and a cam 78 thereon turns the lever 86 so that its nose 102 presses the contact 106 against the insulated stationary contact 104 of the flashlamp circuit. Thereafter at a time determined in accordance with the lag of the lamp, the projection 40 on the sector engages a pin 48 on the latching pawl 18, tilting the pawl anticlockwise to release the master ring 12 to open the shutter. If an instantaneous lamp is used, a slide 118 is moved so that its index 124 registers with a mark X on the shutter casing. In this way a lever 98 is moved clockwise against its spring 100 and the tip 98<SP>1</SP> engaging a cam 96 on the lever 86 moves this lever anticlockwise to hold its tail out of the path of the cams 78 and 80 on the disc 68. Simultaneously a shoulder 132 on the slide rotates clockwise against its spring 128 a plate 126 freely rotatable on the pivot 26 and carrying the star wheel pallet so as to disengage the gear 76 on the star wheel from the gear 70. Consequently on pressing the release, the shutter is opened almost instantaneously and a pin 112 on a bell-crank lever 114 pin and slot connected to the ring 12 is rotated anticlockwise to close the contacts 104, 106 as the shutter opens. Specification 275,462, [Class 98(i)], is referred to.
