Title: An apparatus for the development and after-treatment of exposed photographic film
IPC: G03D3/06
Filed: 1962-08-20
Abstract: 965,341. Photographic processing apparatus. K. GALL. Aug. 20, 1962 [Aug. 23, 1961], No. 31927/62. Heading G2A. An apparatus for processing exposed film comprises a light-tight tank, a continuously rotatable drum which dips below the liquid level in the tank and to which the film can be attached and a separate storage container for each processing liquid, each container having a separate pump, a separate supply pipe, a separate outlet valve and a separate return pipe, the pumps being automatically controlled by a programme switching mechanism so that the various liquids are admitted and removed in the correct sequence. As shown, the tank 2 has a cover 1 and a drum 5 mounted therein and rotatable about its horizontal longitudinal axis 6. The film 12 is clamped to the outer surface of the drum by means of strip 11. The processing operations are controlled by programme switching mechanism 45 (Fig. 2) which by inserting a programmed card 44 causes electric motor 7 to be switched on thus rotating the drum 5. Pump 21 is then energized causing the processing liquid in container 14 to be pumped into the tank 2 via pipe 17. When the first processing is completed the gate-valve 27 is energized and the processing liquid is returned to container 14. If a washing stage is required, electromagnetic valve 34 is opened allowing water to flow into the tank via pipe 19 until the water has reached the height of overflow pipe 35. When the washing stage is completed, gate valve 36 is opened and water is removed via pipe 37. Subsequent processing operations may be carried out by pumping the processing liquids in containers 15 and 16 by pumps 22 and 23 respectively, the discharge of these liquids being controlled by valves 28 and 29 respectively with any intermediate washing stages being performed if necessary. The temperature of containers is controlled by bath 13 containing water circulated by pump 41 via pipes 39 and 38. The bath may be heated by elements 42 or cooled by the addition of cold water.

Title: Improvements in or relating to a radio location and identification system
IPC: G01S13/02
Filed: 1945-11-28
Abstract: 617,737. Radiolocation. NOVY, J. F. Nov. 28, 1945, No. 32144. Convention date, Sept. 23, 1944. [Class 40 (vii)] In order to identify the responses displayed on a radar indicator, a separate D.F. system is provided responsive to radio signals of a different frequency emitted independently of the radar system by the object producing the responses, the output from the D.F. receiver being applied to modify the radar responses. The invention is described as applied to a pulse radar system with a plan-position indicator (P.P.I.) display produced by rotating the timebase deflector coils 8 of an intensity-modulated cathode-ray tube 7 in synchronism with a directive rotating aerial system 3 by means of selsyns 11 and 12. A separate goniometertype direction-finding system is provided having a cardioid directional characteristic produced by crossed loops 16 and an open aerial 18, the null of the cardioid being maintained in alignment with the radar beam by means of a further selsyn 20 coupled to the rotor of the goniometer 17 The negative output from the D.F. receiver 19 is applied to a valve 21 with a relay in the anode circuit, Fig. 2 (not shown), so that when the output falls to zero the valve becomes conductive and operates the relay which shorts out a resistor 10 in the biassing network of the cathode-ray tube to brighten the screen over a narrow sector. Thus, if a number of responses corresponding to different objects, e.g. aircraft, on different bearings are displayed on the screen and only one object is transmitting signals picked up by the directionfinder, the radar response corresponding to that object will be located in the brightened sector.

Title: Improvements in and relating to transmission circuits for wireless telegraphy and telephony
IPC: H03H2/00
Filed: 1920-11-15
Abstract: 175,402. Macrorie, A. K., Airey, H. Morris-, and Shearing, G. Nov. 15, 1920. Thermionic oscillation generators; harmonics, absorbing.-In order to eliminate harmonics from an aerial directly excited by a valve oscillation generator, a resistance and an inductance coil are connected in series between one of the main electrodes and the aerial inductance tapping, and one or more tuned circuits designed to by-pass the harmonics are connected between the other main electrode and the junction of the inductance and resistance. As shown in Fig. 1, the plate of the valve generator V is connected to the tapping point K of the aerial inductance L through a capacity C1, inductance L1, and resistance R, and a shunt, comprising inductance L2 and capacity C2 in parallel, is connected between the earthed filament and the junction point R, L,. The inductance-capacity products L, C1 and L2 C2 are made equal to the product LC for the aerial. The shunt L2 C2 allows harmonics to pass but offers high impedance to the fundamental oscillations. The resistance R prevents subsidiary oscillations from being set up in the circuits LKRC2, or CKRC2. The circuit L2 C3 may be replaced by one or more branches, each comprising inductance and capacity in series, and each tuned to an harmonic. The elements R, L1, C1 may be connected in the filament lead instead of in the plate lead. The grid circuit may be coupled inductively or directly to the aerial inductance.
