Title: Improvements in the manufacture of sound films
IPC: G03C5/14
Filed: 1930-09-04
Abstract: 368,852. Kinematograph films; photosensitive layers. SCHINZEL, K., 4, Beethoven Place, Troppau, Silesia, Czecho - Slovakia, Sept. 4, 1930, No. 27626/31. Convention date, Sept. 4, 1929. Divided on 369,221. [Class 98 (ii).] In making photographic sound records, films are used having a highly sensitized grainless or very finely grained emulsion, such as a Lippmann emulsion with a size of grains between À1 to À5 microns. The sensitizing may be effected bv means of ammonia and dissolved silver salts with the addition of sensitizing dyes such as eosine or pinaflavol. The emulsion is protected by a layer of gelatine, casein, dextrin, &c., permeable by the developer. Specification 369,221 is referred to. The Specification as open to inspection under Sect. 91 (3) (a) on the 5th October, 1931, refers also to the use of hydrogen peroxide and isocyanines for sensitizing the emulsion. It further states that the protecting layer of gelatine &c., or an intermediate film between the carrier and the emulsion, for preventing halation, are preferably coloured with red or other dyes that can easily be decoloured or washed out. This subject-matter does not appear in the Specification as accepted.

IPC: G01T7/06
Filed: 1957-09-02
Abstract: 859,172. Nuclear reactors. UNITED KING- DOM ATOMIC ENERGY AUTHORITY. Dec. 2, 1958 [Sept. 2, 1957], No.27628/57. Drawings to Specification. Class 39(4). In a nuclear reactor, the detection of burst fuel element sheaths is effected by sampling the coolant leaving the fuel element channels at precipitator units. The channels are monitored in turn and the signals converted to tape perforation which controls a computer. The latter produces two signals which are respectively a comparison between the currently recorded signal and the mean of the last two signals from the same channel, are a comparison between the currently recorded signal and the normal signal from same channel. Alarms are operated by the computor outputs. The channel readings are compensated for overall activity variation due to reactor power level changes.

Title: Improvements in or relating to photographic cameras and interchangeable objectives therefor
IPC: G03B3/00
Filed: 1938-09-23
Abstract: 517,493. Photographic cameras. KODAK, Ltd. Sept. 23, 1938, No. 27742. Convention date, Sept. 23, 1937. [Class 98 (i)] In a camera using interchangeable objectives, the objective is carried by the focusing means which is locked against movement upon removal of the objective therefrom. The objective 1 and its mount 2 are detachably held on a focussing mount by a lock nut 3, the tubular member 4, integral therewith, being held against rotation by a pin 5 and moved axially by means of a screw-threaded connection 7 with a focussing sleeve 6. A pin 11 in the lens mount 2 moves in a slot 13 of a rigid arm 14. The sleeve 6 is rotated through gears 9 by a focussing knob 8. The lock-nut 3 may be avoided by employing a screw-threaded connection 10 for the mounts and the member 4. A ring 15 is carried by the sleeve 6 and has an opening 16 which lies opposite the slot 13 when the objective is focussed for infinity, thus allowing the objective to be withdrawn. As the objective is removed, a spring-urged hook member 17 is swung into a hole 20 in the ring 15 and prevents movement of the focussing mechanism. The member 17 is pressed back when another objective is inserted.

Title: Improvements in transmission mechanisms
Inventor: RENDEL DAVID GEORGE AIDAN
IPC: F16D63/00
Filed: 1948-10-26
Abstract: 654,326. Controlling aircraft. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Oct. 26, 1948, No. 27839. [Class 4] [Also in Groups XXIV and XXXIV] A rotary shaft 1, Fig. 1, for transmitting power, particularly for operating control surfaces of aircraft, is adapted under certain circumstances to pivot about a transverse axis at 2 to bring a brake disc 5 on the shaft into engagement with a fixed friction block 6 or to release this brake. Thus if 3 and 4 are input and output pulleys or sprockets respectively, and the operating cables or chains are run downwardly then power supplied at the input end to rotate the shaft in either direction will tend to cause the brake to disengage whilst a rotational load applied at the output end tends to apply the brake, thus producing an irreversible mechanism. In a modified arrangement the input pulley 3 is replaced by a pinion which is engaged by a rack which on operation in one direction applies the brake but in the other direction releases it. A double-acting form of such an arrangement is shown in Fig. 3 in which a control column 23 operates an aircraft control surface 41 through racks and pinions 25, 29 and 26, 30, shaft 1 and gearing 36, 38, 39. Movement of the column 23 to either position A<SP>1</SP> or B<SP>1</SP> will operate either of lever systems 27 or 28 to rotate the shaft 1 through rack 25 or 26 to operate the control surface 41 to position A or B. Either of these movements pivots the shaft 1 about 2 in a brake-releasing direction so that a free operation results. When a return movement of the column 23 from position A<SP>1</SP> or B<SP>1</SP> is effected, however, the shaft is moved in a brake-applying direction so as to oppose the air load acting on the control surface 41 and tending to restore it to the neutral position.

Abstract: 1,039,622. Lasers. COMPAGNIE GENERALE D'ELECTRICITE. July 9, 1964 [July 10, 1963], No. 28440/64. Heading H3B. A prism has one face placed against one face of a crystal laser cut as a right-angled prism, the opposite face of which is plane in order to suppress oscillations and is displaced away from the crystal to allow oscillations. As shown in the Figure a ruby crystal 9 of the form shown is pumped by a Xenon flash lamp 16 controlled by device 22. In order to suppress oscillations a right-angled prism 12 is placed with one face 15 against face 11 of the crystal so that internal reflections do not occur, faces 13, 14 being coated with antireflection material. When a charge 4 of pistol 1 is detonated a piston 5 moves across a beam of light from lamp 17. An electrical impulse from photo-cell 19 is thus passed to device 22 which causes flash lamp 16 to ignite and pump the active medium. Piston 5 also strikes prism 12 to displace it from crystal 9 so that the latter acts as an optical resonator and stimulated emission occurs. Delay line 21 is inserted so that the piston strikes the prism at a time after the lighting of the flash lamp 16 when maximum inversion of population is achieved in the active medium. The rapid displacement of the prism may be produced by a hypersonic shock-wave generated in a shock tube.
