Patent GB-263191-A (GB)
Title: Process for the production of 2-amido-4-nitrophenoxyethanol or -propandiol
Filed: 1926-12-18
Abstract: 263,191. Chemical Works, formerly Sandoz. Dec. 19, 1925, [Convention date]. 2-Amino-4-nitrophenoxy-ethanol orpropandiol, which may be used for the preparation of dyestuffs, are obtained by treating 2: 4-dinitrophenoxy-ethanol or -propandiol with reducing agents, in particular with alkali sulphides or polysulphides. In an example, 2: 4-dinitrophenoxypropandiol is warmed with sodium tetrasulphide; on cooling and neutralizing, an orange precipitate of the nitramine is formed. This is freed from sulphur by dissolving in hydrochloric acid; the base may then be precipitated with soda, and recrystallized from water. The corresponding nitroaminoethanol may be similarly obtained from 2 : 4-dinitrophenoxyethanol. 2:4-Dinitrophenoxyethanol is made by heating 2 : 4-dinitrochlorbenzene with glycol and soda.

Title: Diaphragm with wide compensation for light
IPC: G03B9/08
Filed: 1973-07-06
Abstract: 1440653 Iris diaphragms SOC D'OPTIQUE PRECISION ELECTRONIQUE E MECANIQUE 6 July 1973 [6 July 1972] 32280/73 Heading G2J An iris diaphragm with a plurality of blades pivoted on a casing and controlled by a rotating member has a graduated filter carried on a support member pivoted on the casing, there being a first phase of operation in which the blades progressively reduce the aperture from full to a predetermined size while the action of the filter remains constant, and a further phase in which the blades remain stationary at the predetermined aperture and the filter is progressively displaced to dispose increasing density in the aperture. As the two connected control rings 2, 3 Figs. 2, 3 are rotated through angle a<SP>1</SP>, the diaphragm blades 7 and blade 8 having the filter 10 are moved towards the predetermined small aperture, the filter then lying behind a diaphragm blade. On further rotation through angle a<SP>2</SP>, the diaphragm blades on pivot C have their actuating pins d confined in a part of cam slot 11  which is concentric to the aperture axis and therefore do not move, while the filter blade actuating pin d moves down an inclined portion of its cam slot 12 to progressively bring portions of the graduated filter 10 into the reduced aperture. In the embodiment of Figs. 4, 7, the filter 10 is carried on a transparent blade 8 covering the full aperture. During the first phase, the diaphragm blades close to the small aperture as in Fig. 7, the filter blade 8 staying fixed due to the concentric cam slot 13 within angle a<SP>1</SP>, Fig. 4. Movement through angle a<SP>2</SP> then keeps the diaphragm blades fixed due to the concentric part of slot 11 while the filter is moved progressively across the small aperture by the radially inward sloping part of slot 13. Further rotation through angle a<SP>3</SP> may completely close the aperture. The inter-connected diaphragm and filter blades may be in a single or separate housings.

Abstract: 1,001,276. Washing granular materials. PREPARATION INDUSTRIELLE DES COMBUSTIBLES. Aug. 22, 1962 [Sept. 4, 1961], No. 32302/62. Heading B2H. Apparatus for densimetric separation of solids comprises two wash boxes 1 and 2 with an arrangement as at 4 for lifting the heavy fractions which is mounted upright in a plane parallel to the direction of flow of the light products in the washboxes, the point of discharge 20 of the heavy fraction from the apparatus being positioned between points of discharge 18 and 19 for the light fractions. Heterogeneous raw material is fed into washbox 1 in the direction 13. The light fractions float on the liquid in the washbox and pass over the weir 18. The heavy fractions collect along the sloping wall 3 whence they are lifted by the wheel 4 and discharged into a shoot 6 by the conical hub 5 of the wheel. A bifurcated spreader 7 and 8 discharges the heavy fractions into the washbox 2 where the lighter fractions float over the weir 19 whilst the heavy fractions are lifted from the sloping wall 9 by a wheel 10, similar to that at 4, into a shoot 12 for discharge at 20. Alternatively the same raw product or different products may be fed to both washboxes separately and the heavy fractions from each be discharged from shoots 6 and 12 symmetrically rearranged.

Title: Improvements in or relating to conveying or like apparatus
IPC: B65G47/54
Filed: 1925-12-22
Abstract: 261,934. Carey, H. D. de M. Dec. 22, 1925. Discharging devices for endless rope conveyers; parallel ropes without cross-connections.- Means for transferring articles from a main conveyer to an auxiliary conveyer arranged substantially at right-angles thereto comprises a carriage provided with rollers which is adapted to be raised above the level of the main conveyer. The main conveyer a, Fig. 3, comprises a number of parallel bands b to which are attached blocks c provided with rollers d which run on rails e. Wheeled carriages f supported by rails g, h, Fig. 1, are disposed between the ropes b and each supports a rotatable roller i formed with a helical groove o of progressively decreasing pitch which is engaged by a pin n slidably mounted in a relatively fixed guide member p. A pin provided at the forward end of each carriage f can be raised above the level of the conveyer by electrical or mechanical means so as to be carried forward when struck by an article. The forward movement of the carriage brings the wheels on to the inclined portions of the rails g, h and also causes the rotation of the rollers i, so that the article is removed from the conveyer and moved laterally towards the conveyer r. If the rotation of the rollers is insufficient to effect the transfer of the article, an arm actuated electrically, by compressed air, or by the main conveyer may be provided to push the article. The carriages f may be moved by connecting rods s connected to the pistons of cylinders to which fluid pressure is admitted by a device having a connection t extending to one of the pins u forming part of a shock absorber for the pin j. The pins u are connected to a block v in which the pin j is mounted. When the carriages are moving forward, backward movement is prevented by the engagement of a pawl l mounted on the pin j with a rack m. 'When the pawl reaches the end of its travel, the pin j drops, and as the carriage returns to its initial position, the pawl moves along the underside of a bar w. The return movement of the carriages is effected either by the power used to drive them forward, or by means of rods a' connected to double-armed levers b<1>, of which one arm is tripped by an oncoming article.

Title: Isotope heated thermal batteries
IPC: H01M6/36
Filed: 1967-07-13
Abstract: 1482737 Thermal batteries CATALYST RESEARCH CORP 13 July 1967 32404/67 Heading H1B The useful operating time of a thermal battery which is activated by melting a solid electrolyte by heat derived from a combustible composition, is greatly extended by moving an auxiliary heat source in the form of a radioactive isotope into heat transmitting relationship with the battery so that the battery temperature is maintained after the combustible composition is expended whereby the electrolyte remains molten and the battery continues to provide electricity. As shown, the battery is annular and comprises electrodes 16, 18 spaced by pads 17 impregnated with fuzible electroyte and pads 20 impregnated with a combustible material. The pads 20 are connected by combustible strips 21 and are ignited by a device 38 connected by leads 40, 42 to a firing circuit 34, 36. A tube 4 extending through the battery housing 2 has an extension receiving a capsule 27 containing a radio-active isotope 28, e.g. Sr<SP>90</SP>TiO 4 . This capsule is retained against the action of a spring 32 by a fusible wire 29 extending through a hook 30 and connected by leads 46, 48 to the circuit 34, 36. Thus simultaneously with the action of the igniter 38 the wire 29 burns to release the capsule 27 and the heat generated by the isotope is transmitted to the battery.
