Abstract: 1,233,240. Photographic processing apparatus. ARTISAN INDUSTRIES Inc. Dec. 10, 1968, No.58756/68. Heading G2A. A film strip transport device for use in photographic processing apparatus has means for taking into account contraction of film being processed. A rack 10 has a main rotor shaft 16, externally driven, which shaft in turn drives a primary rotor shaft 22 and a floating rotor shaft 54. The shaft 22 carries primary overdriven spools 36, 38, 40 and the shaft 54 carries two friction drive rollers 56, 58 normally out of contact with the two enlarged primary spools 36, 38. Two rods 46, 48 depend from the shaft 54, the rods 46, 48 being movable vertically and laterally in slots in support plates 42, 44. The rods 46, 48 carry shafts 60, 64 which in turn carry discs 62 and secondary elevator spools 70 respectively. Film to be processed is arranged in a loop to loop arrangement between the spools 36, 38, 40 and 70. An increase in film tension in the incoming film results in the frame of shafts 54, 60, 64 and rods 46, 48 moving vertically and laterally (to the left as seen), thereby bringing the roller 56 into contact with the spool 36 Fig. 4 (not shown). This increases the feedrate into the rack, relieving the tension and the frame floats back into its normal position as shown. The lateral movement also minimizes the amount of tension variation within the loops. Successive racks are arranged in tanks for successive treatments. When a first rack takes film from a second rack, the second rack will supply the reserve film without seeking film from a third rack. This is normally accomplished without the left hand roller in the second rack engaging its own primary feed spool, although the right hand roller may contact the primary output spool.

Abstract: 1,253,075. Film magazines. EASTMAN KODAK CO. Nov.21, 1968 [Nov.24, 1967], No.55367/68. Heading G2A. A cartridge for containing and supplying sequentially to a camera a stack of slide transparency units which are to be developed within the camera, is in the form of a box-like housing H, inside which fits a cover C for the stack of slides 17. These rest on a blank 19, and are of the type having rupturable pods 18 of developing material. Blank 19 has upturned light baffles 25, 26 at its ends. The slides are urged downwards against blank 19 by a leaf spring 34 acting via a pressure pad 35 having upturned ends 36, and a second blank 37. A divider 38 is provided above the spring. When the cartridge is inserted into a camera, a reciprocal slider mechanism engages the blank 19 and pushes it out of an opening 33 in the direction of arrow 39, into an exposure position in the camera, the baffles 25, 26 folding down flat during this movement. A second actuation of the slider mechanism pushes the first transparency out of the cartridge into the exposure position, and the blank 19 out of the camera. A further actuation of the slider moves another transparency into the exposure position, at the same time pushing the previously exposed (and by now processed) transparency out of the camera. When the last transparency has been exposed, subsequent actuation of the slider pushes the blank 37 into the camera. After a transparency has been exposed and developed, it can be replaced in the slider for storage by insertion through a slot 40 in the cover C. It is deflected downwards by a transverse rib 43 so as to allow insertion of the next transparency. These stack up above the divider 38, which is now loaded upwards by spring 34. To form a permanent storage chamber the cover C is put on in a reversed position, which provides a more complete enclosure.

An I.C. engine fuel feed device comprises in the induction pipe 1, Fig. 1, upstream of a main throttle 2, Fig. 2 an auxiliary throttle 3, Fig. 2 which opens automatically with increasing airflow, means for injecting liquid fuel into the induction pipe downstream of the main throttle and a metering system which responds to the auxiliary throttle position to keep the fuel air mixture ratio constant. The metering system comprises a disc 14 rotated by the engine between a light source 16a and a light-sensitive cell 17 which are mounted on a common support connected to the auxiliary throttle. The disc has ports 19 which admits the light beam to the cell 17 to cause energization of an electromagnetic fuel injector 12. The support 18 is moved so that the electromagnet is energized during a fraction of each revolution of the disc which varies in accordance with the degree of opening of the throttle member. Each port is associated with a spring-loaded lever 29 which acts under centrifugal force to mask part of the port 19 when the auxiliary throttle is in the idling position to reduce the period of energization of the electromagnet. An amplifying relay 25 and an intensity limiting device 26 may be inserted between cell 17 and electromagnet 13. In multicylinder applications each cylinder is supplied by a separate electromagnet 13 energized through a distributer 27.

Abstract: 1,266,830. Gas turbine plant. E. I. JANELID. June 29, 1970 [June 30, 1969], No.31394/70. Heading F1G. The invention relates to a gas turbine plant of the kind in which at periods of low power demand, the air compressor of the engine forces air under pressure into a storage chamber, such as an underground cavern so driving out a volume of water, and in which at periods of high power demand water flows into the storage chamber to force out air under pressure to the gas turbine plant during which operation the compressor is preferably disconnected; when the power demand is low, water is forced out of the storage chamber to a reservoir having a relatively low level whereas when the power demand is high, water flows into the chamber from a water reservoir having a relatively high level. The plant shown in Fig. 1 comprises a gas turbine 1 which drives a compressor 5 through a coupling 6, air from the compressor passing through lines 7, 8 to the turbine to which fuel is supplied through line 2. The turbine drives also an electric generator 4. At periods of low power demand air from the compressor passes also through line 9 and passage 10 to an underground cavern 11 thereby forcing out water through passages 13 and 16 to the low level reservoir 20, the valve 17 being open. At periods of high power demand the valve 17 is closed and valve 18 opened whereupon water flows from the high level reservoir 21 through passage 18, 13 to the cavern so forcing out air from the cavern through passage 10 and line 9 to the gas turbine, the compressor 5 being now disconnected so that the full turbine power is available to drive the generator 4. In Fig. 2, valve 17, 22 are provided in the passage 16 and a motor-driven pump 25 is operated during periods of low power demand to transfer water from the low level reservoir 20 through passages 23, 24, 18 to the high level reservoir 21. In Fig.3 (not shown), a pump 25 is again utilized to raise water from the reservoir to a higher level but the passage 24 is connected directly to the passage 13, the reservoir 21 not being utilized. In Fig.4 (not shown) at high power demand the pump 25 forces water from the reservoir 20 through passage 27 into the passage 13 such that the water level 30 in the passage 13 is maintained at the desired level. In Fig. 5 (not shown) the pump 25 is disposed in passage 28 at such a level that it is below the level to which the compressor is able to force up water from the cavern. The pump serves to raise the water the extra height to the reservoir 20.
