Patent GB-1405475-A (GB)
Title: Photographic film unit
IPC: G03C8/34
Filed: 1972-09-07
Abstract: 1405475 Self-processing film units EASTMAN KODAK CO 7 Sept 1972 [7 Sept 1971] 41564/72 Heading G2X In a self-processing film unit a reservoir for processing fluid (which may be either a supply pod or a trap for excess fluid) is readily detachable from the image-recording portion. Fig.2 shows an exploded view of the film unit, comprising a photo-sensitive element 11 and a transparent process or cover sheet 13, permanently secured together along their lateral margins 15. The processing fluid is supplied in a rupturable pod 23, guided between the sheets 11 and 13 by a funnel formed by sheets 33, 34, and any excess guided out again at the farther end by another funnel formed by sheets 39, 40 into a trap 9. Each of the sheets 33, 34 has a first portion 61 securely attached to the supply pod 23, and a second portion 63 securely attached to either sheet 11 or sheet 13. Between these two portions 61 and 63 is an intermediate unattached portion 65, so that portions 61 and 63 can be separated by tearing along the intermediate portion, as shown in Fig.3. A similar construction at the other end enables the trap portion 9 to be torn away. The coupling portions are made from sheet materials which are strong in tension but weak in shear, a preferred paper being specified. Thus the film unit can be handled and submitted to pulling means without causing a premature separation of the reservoir sections from the image-bearing section.

A floating-roof gas-seal arrangement comprises a flexible, impervious, wear resisting tube 10 pressurised internally so as to contact the tank side 2 and the roof side 6 and supported at two vertically spaced positions on the roof side by connections 12 and 24 which anchor the tube and allow it to conform with the upward and downward movements of the roof. The upper anchorage 12 is a lip on the tube which is clamped at 16 to the roof top. The lower anchorage 24 comprises a downwardly directed flange 31 on the wall side 6 which is engaged from beneath by hooks as at 26 (Fig. 3), 131 (Fig. 6) or 56 (Fig. 9); item 52 in the latter being a sectional view of a cable ring which is embraced as shown by the wall of the tube 10. Rotation of the roof may be prevented by spaced vertical bars 32 on the side 2 which engage with grooved shoes 36 which are flexibly supported on the roof at 40 and 42 (Fig. 7). Wheels 146 on spring-loaded arms 140 may be provided to assist in keeping the roof central and gas supply means 106 (shown in part in Fig. 5) may be used to maintain the tube at the correct pressure. A flexible weather shield 136 may be fixed to the periphery of the roof. The tube may be an integral annulus or be built up as lengths connected by fabric cylinders.

Abstract: 1411688 Statistical radar CONTRAVES AG 12 Sept 1973 [12 Oct 1972] 42781/73 Heading H4D In a statistical type pulse radar, the roles of accumulator, or up-down-counter and a "target"-"no target" decision making logic circuit are collectively performed by a suitably programmed read only memory (R.O.M.), FS, of a type stated to be readily available and a one repetition period delay register SR coupling the output of the ROM to its input, the output of the "echo/no echo" quantizer being fed as an updating signal to the input of the R.O.M. With a pulse repetition period of 100 Ásecs., the five bit shift register SR has 100 stages 0 to 99 shifted by 1 MHz pulses t from generator T. Binary weighted inputs a, b, c, d, e, of the R.O.M. have values 1, 2, 4, 8, 16, with an "echo" signal if at input f from quantizer F having an updating value of 32. Similarly the outputs A, B, C, D, E of the R.O.M. have values 1, 2, 4, 8, 16, with the last three outputs X, Y, Z giving 1 signals respectively indicating accumulated target indicating threshold being maintained, threshold just attained, threshold just left. The relationship between the value of inputs a, b, c, d, e (former accumulated sum) and the value of outputs A, B, C, D, E (fresh accumulated sum), in dependence on whether or not an echo signal is present at input f, may be summarized as follows The target attained threshold is 17, so that outputs X and Y give 1 outputs when 17 is first accumulated, and the target lost threshold is 12 so that X becomes 0 and Z gives 1 when 12 is reached in a decreasing count. Fig. 2 gives an example of the accumulated sum Ia (0-21) as a result of echoes from an extended target 01 (echoes being indicated by a complete downwards arrow) together with the 1 pulses of Y (during 17th p.r.p.), of X (from the 17th to 43rd p.r.p.) and of Z (during 43rd p.r.p.).

Title: Improvements in or relating to power generating plant comprising a gas turbine
IPC: F01K23/06
Filed: 1961-11-30
Abstract: 955,298. Gas and steam turbine power plant. ATELIERS ET CHANTIERS DE BRETAGNE ANCIENS ETABLISSMENTS DE LA BROSSE & FOUCHE. Nov. 30, 1961 [Dec. 27, 1960], No. 42945/61. Headings FIG, FIL and F1Q. [Also in Division F4] In a power generating plant the gases produced in a combustion chamber are utilized in part to drive the shaft of a gas turbine and in part to generate steam to drive a steam turbine which drives a compressor supplying air to the combustion chamber, the steam to the turbine being controlled by a regulator in accordance with the fuel feed rate to the combustion chamber. A combustion chamber 3 is fed with the minimum amount of air for combustion by a compressor 2. The air is supplied through pipes 6, 7 leading to burners 4, 5. The combustion gases are cooled to an acceptable temperature for delivery to a gas turbine 1 by generating steam in a boiler 11, lining the combustion chamber 3, and superheating the steam in a superheater 12, during their passage to the turbine 1. One or more burners 5 are provided in the combustion chamber to adjust the temperature drop of the gases in the superheater 12 and at the inlet of the turbine 1 when the latter is operating at low speeds. The turbine 1 exhausts through an auxiliary boiler 13 and an economizer 14 to a chimney 28. Water, fed into the economizer 14 at 16, passes to the boiler 11 at 18 and to the auxiliary boiler 13 at 17. Both boilers 11, 13 pass saturated steam through pipes 19, 20 to the superheater 12. Steam passes from the superheater through piping 23, 24 to steam turbines 8, 9 which exhaust to a condenser 10, and a branch pipe 25 supplies steam for driving auxiliaries, such as feed pumps or air separators or other machines or for heating. A regulator 26 controls the feed of steam to the turbine 8 to vary the speed of the compressor 2 to provide a constant relation between the air delivery from the latter and the fuel flow from the burners 4 and 5. A regulator 27 controls the feed of steam to the turbine 9 to maintain constant pressure in the boilers 11, 13. The plant may be started by steam supplied direct from the boiler 13 to the turbine 8, the boiler 13 then being heated by an auxiliary burner 15. The plant may be used for production of electrical energy, propulsion of ships or land vehicles, or for joint generation of power and steam.

Abstract: 1,045,317. Television. M. GRUNDIG. Oct. 30, 1964 [Oct. 30, 1963], No. 44382/64. Heading H4F. In an image transmission systemthe lineby-line scanning of an image by a camera K, which includes a vidicon tube B A , is controlled by a crystal-controlled oscillator Q s  acting through a frequency diver F s  brought into operation by a start pulse from a signal generator J produced on closure of switch T, the oscillator Q s  and divider F s  normally being prevented from passing timing signals to camera K by a bias voltage applied to their output circuits. The picture signal and start pulse (synchronizing signal) are transmitted by transmitter 1 by radio or wire circuit 2 to receiver 3 where the synchronizing signal is distinguished by gate A from the picture signal and passed to an oscillator Q E  and divider F E , similar to oscillator Q s  and divider F s , to start the writing scan in charge storage tube B w , the charge image being scanned by a further electron beam and made visible on a cathode-ray tube. The synchronizing signal is arranged to maintain the receiver scan in synchronism with the transmitter signal, correct phase in the signal from oscillator Q E  being ensured by momentarilystopping the oscillator and restarting it at a predetermined part of its oscillation cycle. At  the completion of the reading scan of the image in the transmitter a stop pulse is provided by generator J which stops the scanning in the transmitter and receiver. The above arrangement allows for better use to be made of a given band width without loss of image detail since a synchronizing pulse is transmitted only once during the image scan and not every line.
