Abstract: 1413399 Surface condensers ORMAT TURBINES (1965) Ltd 21 Aug 1973 [5 Sept 1972] 39626/73 Heading F4S [Also in Division F1] A method of operating a closed Rankine cycle power plant under low temperature ambient conditions, said power plant including a surface condenser, comprises arranging the condenser to permit the freezing of condensate on the inside of the condenser to form a heat sink and without blocking the flow of vapours into the condenser. The system described uses an organic fluid such as ortho-dichlorobenzine as the working fluid. As shown, the condenser comprises inclined, externally finned tubes 35 each closed at its outer end, said tubes extending from a header 33 and being supplied with vapour through one or more tubes 34. The header 33 and tubes 34 are covered with a heat insulating material 39. 36 is a passage for condensate running out of the tubes 35 and returning to the boiler of the plant (Fig. 1), said passage 36 extending through tubes 34. At low ambient temperature conditions a layer 40 of frozen condensate forms inside the tubes 35 and comprises a heat sink. The thickness of the layer 40 increases as ambient temperature falls and decreases as it rises. The variable heat rejection capability thus provided by the changing thickness of the frozen layer 40 serves to maintain substantially constant the temperature conditions within the condenser tubes regardless of the preventing ambient temperature.

Abstract: 1,046,597. Conveyer systems. FISHER & LUDLOW Ltd. Oct. 4, 1965 [Oct. 2, 1964], No. 40091/64. Heading B7L. In a conveyer system similar to that described in Specification 982,436, a stop device 9, Fig. 1, for stopping a load carrier trolley 8 on its track 7 after the trolley has been disconnected from the driving dogs on an endless power-driven chain, comprises a channel-sectioned arm 10 pivoted to the track about a vertical axis at 11 and a stop member 17 slidable lengthwise of the arm 10 against the urge of a leaf-spring assembly 29 and which member 17 after moving a predetermined distance relative to the arm 10 can swing laterally outwardly of the arm so as to be disengaged from the trolley. As shown, the stop member 17 has a portion 19 passing through a slot 16 in the arm 10 and a rear lug 26. The number of spring leaves 30 is varied in accordance with the loading of the trolleys of the system and the ends of the assembly 29 abut the lug 26 and the front closed end of the channel sectioned arm 10. The front end of the member 17 is T-shaped and one limb 21 of the T is engageable by the trolley 8 whilst the other limb 23 has an abutment face 24 which engages an abutment face 25 at the front end of the arm 10. When a trolley 8, which has been disconnected from the driving chain dogs (not shown), engages the limb 21 the momentum of the trolley will cause the member 17 to slide in the arm 10 against the urge of the spring assembly 29 until the trolley is brought to rest with the end 24a of the face 24 still in abutment with the end 25a of the face 25 as described with reference to Fig. 2 (not shown). However, should the conveyer mechanism be faulty and the trolley is still, e.g. positively driven, the member 17 will slide to the position in which the abutment faces 24, 25 disengage and the member 17 will then be swung outwardly of the arm 10 by the trolley by pivoting about its end 18 on the web 15 of the arm 10, as described with reference to Fig. 3 (not shown).

Abstract: 1,109,328. Photographic shutters. PENTACON DRESDEN KAMERA-UND KINOWERKE VEB. Sept. 9, 1966, No. 40387/66. Heading G2A. A photographic shutter has two spring driven blades 4, (5) Fig. 2 (not shown) which are brought to a halt by non-displaceably mounted brake lugs 41, 38 after they have uncovered and recovered the aperture 21. As shown, a slider 53 has cocked the shutter and is about to move to the left under spring action. To effect an exposure, a lever 13 is turned clockwise thus freeing levers 9, 11 to rotate clockwise under the action of springs 17, 16. Movement of the lever 11 rotates the shutter blade 4 anticlockwise by means of a segment arm thereof meshing with a pinion (6), thus uncovering the aperture. Near the end of its movement the blade 4 engages the lug 41 and is brought to rest thereby. The running down of the lever 11 is delayed in a known manner by a pre-set escapement mechanism, but eventually the blade (5) is halted by the lug 38. In the last part of the movement of the lever 11, an arm 48 thereof pivots a pawl 49 out of engagement with a lug 50 on a ring 43 which is rotated clockwise by means of a spring 47. Shift dogs 45 on the ring are brought into engagement with the lugs 38, 41 which are thereby disengaged from the blades. Cocking the shutter. The slider 53 is moved to the right engaging part of the lever 9 and thus moving the lever to the position shown. The lever 9 carries with it, via a nose 14 and a lug 15, the lever 11 and the two levers are held as shown by the lever 13. The last part of the movement of the slider 52 carries with it an arm 46 of the ring 43 which thus rotates the dogs 45 out of engagement with the lugs 38, 41 and brings the lug 50 back into engagement with the pawl 49.

Abstract: 1443493 Data storage systems; pipe-line control INTERNATIONAL BUSINESS MACHINES CORP 18 Sept 1974 [30 Nov 1973] 40633/74 Heading G4A The operation of each of a plurality of storage units 10, Fig. 1B, is controlled by timing pulses from a respective clock-driven ring counter 14, and control information is shifted along a plurality of shift registers 20-30, Fig. 1A, in synchronism with the stepping of the ring counters so as to be available at outputs of the shift registers to control the function of the storage units 10 at the appropriate times. An 8-byte data word and its associated check byte is addressed in a selected one of the storage units 10 via a decoder 16 and one of the address registers 12. At the same time as the address is applied, 4 select bits are fed in parallel to shift register 20 and simultaneously start the ring counter 14 for the selected storage unit 10. Depending on the operation to be performed, control bits are also supplied to shift registers 22-30 and data bits, in parallel, to a shift register 32. For a store operation, the outputs of stages SR1 of shift registers 20, 22 are gated together and delayed to enable gates 44 to pass the data from stage SR2 of shift register 32 to the selected address in the selected storage unit 10. Because of the pipe-lining facility provided by the shift registers, a store operation may be performed in one storage unit 10 concurrently with a partial store operation in another unit 10. The latter operation is initiated by a control bit in shift register 24 and 8 bits plus a parity bit in shift register 30 to identify which bytes of data addressed are to be replaced by corresponding bytes of data from shift register 32. The required data is fetched from the addressed storage unit 10 at a time when the corresponding control information and replacement data is located in stage SR4 of shift regissters 30, 32 so as to pass the required updated data to stage SR5 of register 32. A new check byte is generated, 40, 38 before entry into stage SR6 and return to the storage unit 10 via gates 40 which are enabled by stage SR6 of register 20, the select bits only reaching this stage when a partial store operation is called for. A fetch operation is performed in default of the store and partial store operations.

Abstract: 410,609. Colour photography. NORDMANN, C., Observatoire de Paris, Paris. May 1, 1933, No. 12651. Convention date May 27, 1932. [Classes 97 (i) and 98 (ii).] Colour-record images on a lenticular film V are reproduced by direct projection on to a sensitive lenticular film C with any desired degree of magnification, and the images are produced on the copy film C so as to be capable of projection with correct colour rendering in any pre-determined projection-apparatus. In taking the images on the film V, the elementary images of the taking filter are formed under each lenticular element in positions depending on the relative positions of the film and filter and on the distance of the element from the optical axis. When projecting the image on the film V, the axes of the beams by which these elementary images are projected from the lenticular elements intersect in a point X at a distance x from the film corresponding to the distance of the filter in the taking operation. The axes of these elementary beams projected on the copy film C by the convergent system defined by the principal planes P1, P2 and principal foci F1, F2, will similarly intersect at a point Y at a distance y from the copy C which defines the position which the filter must occupy relative to the copy C for correct colour rendering in the subsequent projection of the copy. The points X, Y are conjugate with respect to the system P1, P2. When the desired degree of magnification and the position which the filter is to occupy in the apparatus for the subsequent projection of the copy C are known, the focal length #, and the position with respect to the films V, C of the reproducing system P1, P2, may be calculated from equations derived in the Specification from the above stated considerations. Examples are discussed in which x and y are given various values. Reference is made to the correction device disclosed in Specification 360,524 in connection with cases in which y has a negative value. A collimated copy C is obtained from a non- collimated original V if the optical system P1, P2, is chosen so that X coincides with F1. A collimated copy may be obtained from a collimated original if the system P1, P2 is afocal, the components being chosen so that the ratio of the intermediary focal distances is equal to the magnification ratio desired.
