Abstract: 793,352. Luminescent screens. THORN ELECTRICAL INDUSTRIES, Ltd., and SYLVANIA-THORN COLOUR TELEVISION LABORATORIES, Ltd. Nov. 8, 1955 [Nov. 12, 1954; April 7, 1955], Nos. 32917/54 and 10350/55. Drawings to Specification. Class 39(1). [Also in Group XL(b)] In a colour television receiver [see Group XL(b)] the incoming signals are applied to a cathode-ray tube so as to produce on the screen a homochrome image, i.e. an image formed by radiation, specifically greenish white or ultraviolet, of substantially homogenous spectral composition arms the image, and radiation from this image is then diverted to a viewing screen comprising photo-luminescent materials selected to fluoresce in different colours, specifically red, green and blue, and arranged in a repeating sequence of parallel strips disposed transverse the line scanning direction. The screen may receive light by projection or may be disposed on the face of the cathode-ray tube, a lenticular screen in register with the strips being incorporated to reduce loss of light and definition. A filter may be placed over the front-face of the screen to prevent ambient light capable of exciting the photo-luminescent material from marking the screen. Specification 793,351 [Group XL(b)] is referred to.

Abstract: 1475157 Shutter timing circuit KONISHIROKU PHOTO INDUSTRY CO Ltd and MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 25 July 1974 [26 July 1973 12 Nov 1973] 32998/74 Heading G2A  A shutter timing circuit comprises an integrating capacitor Cl which is charged by an amplifier AMP 1  having a negative feedback loop including a non-linear device, preferably a diode D11. In automatic operation a photo-electric element P1 and a resistor VR 11  set according to exposure factors are connected as input to AMP 1 , and in manual operation a resistor VR 31  set according to a manually required exposure time is connected as input to AMP 1 , the non-linear response of AMP 1  providing a capacitor charging current which is an exponential function of the resistance of VR 11  or VR 31 . The voltage on C1 is compared with a reference voltage provided by R61 and R71 by a comparator COM 1  which controls a shutter closing electromagnet 8 1 . The invention enables linearly variable resistors VR 1  1  and VR 31  to be used and enables the same comparator reference voltage to be used for both automatic and manual operation. In Fig. 3, in the automatic mode the input voltage to differential amplifier AMP 1  is the sum of the voltage across VR 1  1  set according to diaphragm aperture and film speed and the voltage developed across a second diode D21 by the photocurrent from P1. In the manual mode the input voltage is the sum of the voltage set by shutter time resistor VR 31  and the voltage developed across D21 by a pre-set resistor VR 5  1 . A memory switch S31 is provided for SLR cameras. In Fig. 4 (not shown), a single resistor (VR32) having two taps replaces VR 31  and VR 11 . In Fig. 5 (not shown) in the manual mode the second diode (D23) is switched out. Fig. 6 (not shown) includes both the Fig. 4 and 5 modifications.

The compounds are prepared by reacting 9-alkyl-9-fluorenol with a compound of the formula X.CO.OR 4  where X is halogen and R 4  is a phenyl group optionally substituted by 1-5 nitro groups and/or halogen atoms, to give the carbonate product. The carbonates may be reacted with hydrazine to give a carbazate which is converted to the azidoformate by treatment with a compound of the formula R 5 NO 2  where R 5  is H, alkyl of 1-5 carbon atoms or an alkali metal, in an acid medium. The amino acid and peptide derivatives may be obtained by acylating an amino acid or peptide with the carbonates or azidoformates of the invention. Amino acid ester derivatives may also be prepared by treating a 9-alkyl-9-fluorenol with a compound of the formula R 3 NCO where R 3  is the residue remaining when the amino group is excluded from an amino acid ester. The amino acid derivatives may be further condensed with another amino acid or peptide. The 9-alkyl-9- fluorenyloxycarbonyl group may be removed from the amino acid or peptide derivatives by treatment with an acid, or by catalytic hydrogenolysis.

Abstract: 344,379. Spring motors. COWEY, L. E., Archer Works, Kew Gardens, Surrey, and VICTORIA WOODWORKING CO., Ltd., 16, City Road, London. Nov. 1, 1929, No. 33308. [Class 10.1 A multiple-spring gramophone motor has the springs interconnected so as to be wound up without intermediate gearing. In the form shown, cases 9, 10, 11, each containing two springs are mounted on arbors 15, 18, 18, 5 on the shaft 6 which is rotated for winding by a toothed wheel 20, connected by a belt 22 to the winding gear. The first spring 12 is fixed at one end to the arbor 15 fast on the shaft 6 and at the other end to the casing 9. As the shaft 6 is rotated, the spring 12 is wound up from its inner end. This causes the casing 9 to rotate, winding the spring 16 up from its outer end, and in turn rotating the arbor 18 to wind up the top spring in the casing 10. The process continues till all the springs are fully wound. Backward rotation of the shaft 6 is prevented by the double ratched device 32, 33, by which the shaft can only rotate backwards for half a tooth. The turntable spindle 2 is driven by gears 3, 4 through intermediate gearing (not shown).

Abstract: 439,766. Purifying exhaust. DEGEA AKT -GES. AUERGES., 16, Rotherstrasse, Berlin. Nov. 19, 1934, No. 33312. Convention date, Nov. 20, 1933. [Class 7 (ii)] [See also Group XXVIII] An exhaust filter in which granular or fibrous filtering material is used comprises two chambers communicating with each other one of which serves as a storage chamber for the other, which serves as a main filter chamber. In Fig. 1 the storage chamber D communicates by means of a conduit F with the main filter chamber C, whilst in Fig. 2 the storage chamber L communicates directly with the chamber H throughout its length. The reserve filtering- material is thus fed continuously by gravity or by spring pressure into the main filter chamber to keep the latter always full. Specification 405,976 is referred to.

The mould 1 may be of several surmounted sections 2, 3, 4, the lowest section 2 being the smallest as it is subject to most wear and requires most frequent replacement. When casting large ingots the melt surface in the mould may be covered with heat-insulating powder.  Foundry plant.-In order to facilitate cleaning and preparation of the mould a stairway and balcony (9) allowing access to the top of the mould may be provided (Fig. 2, not shown).

Abstract: 762,194. Gas turbine plant. DOWTY FUEL SYSTEMS, Ltd., and DEAN, J. S. March 3, 1955 [Dec. 7, 1953], No. 33982/53. Class 110 (3). [Also in Group XXIX] In a liquid fuel supply stem for continuous combustion turbine engines in which a throttle valve 10 actuated by a fluid pressure servomechanism is arranged in a by-pass passageway 9 connecting the inlet and output sides of an engine-driven pump 4 of fixed displacement supplying one or more burners 8, a pressure reducing valve 30 is arranged between the pump outlet and the throttle valve and operates to maintain a constant pressure difference across the throttle valve. The throttle valve 10 comprises a slotted valve member 15 controlling an orifice 14 and operated by a piston 17 subject on its upper side to the pressure in the valve inlet chamber 11. The chamber below the piston 17 is connected to the chamber 18 above it through a restriction 20 in a bleed duct 21, the outlet of which is controlled by a fuel control mechanism 6 operated by a hand lever 7. The mechanism 6 controls the fuel flow in the pump delivery line 5 and is provided with a drain duct 22 to return fuel bled from the duct 21 to the inlet of the pump. The pressure reducing valve 30 comprises a casing divided into three chambers 32, 33, 34 by a flexible diaphragm 35 and a partition 36. The last is formed with an orifice 37 controlled by a valve member 38 connected to the diaphragm by a stem 39. The diaphragm is loaded by a spring 40 adjusted by a screw 41. The chambers 33, 34 and the orifice 37 form part of the by-pass passage 9 between the fuel delivery line 5 and the valve inlet chamber 11. The chambers 32, 33 are respectively subject to the pressures on the outlet and inlet sides of the valve 10 so that the valve 30 maintains a constant pressure drop across the valve 10 dependent on the compression of the spring 40.
