Title: Photosensitive compositions comprising organic halogen compounds
Inventor: FOTLAND RICHARD A
IPC: G03C1/675
Filed: 1970-05-20
Abstract: 1,247,506. Photo-sensitive organic halogen compound compositions. HORIZONS RESEARCH Inc. May 20, 1970 [June 9, 1969], No.24506/70. Heading G2C. A photo-sensitive composition comprises at least one organic halogen compound having at least three halogen atoms attached to one carbon atom and being capable of releasing free radicals when exposed to blue and/or violet radiation, at least one compound capable of forming a coloured reaction product with the free radicals, and at least one aminostilbene, or one aliphatic primary amine, or one alicyclic primary amine or a mixture of two or more of these compounds. Preferably 1 to 50 parts by weight of aminostilbene are used per 100 parts by weight of organic halogen compound, and preferably 1 to 200 parts by weight of primary amine per 10, 000 parts by weight of organic halogen compound. The aminostilbene may be 2, 5-dimethoxy -4<SP>1</SP> -aminostilbene and the primary aliphatic or alicyclic amine may be octadecylamine, cyclohexylamine or methylene -bis-cyclohexylamine. The organic halogen compound may be iodoform and the compound which forms the coloured reaction product may be triphenylmethane. The composition may also contain a triaryl compound of arsenic, antimony, bismuth or phosphorus or an alkyl-substituted phenol. The composition may contain a primary alkyl amine capable of vaporizing to some extent under conditions of storage as, or as well as the aliphatic primary amine. The composition may be coated on a clear support to provide a film. The film is exposed to blue or violet radiation, optically developed by exposing the film uniformly to radiation between the red and infrared regions and fixed by heating the film at 130 to 190‹C. for intervals of from 10 seconds at the higher temperatures to 90 seconds at the lower temperatures. The film is preferably fixed by heating to 150‹C. for 1 minute. The film may be stored, prior to exposure, in a closed container in an atmosphere of a primary alkyl amine to increase its shelf-life. On opening the container and allowing the film to remain in the air for a short period of time, the amine diffuses from the film thus allowing it to function in a normal high speed manner. Films produced with the above-defined compositions have an increased shelf-life at room temperature relative to the shelf-life of similar films not containing the aminostilbene or primary amine compounds.

Title: Improvements in and relating to propulsion of aircraft
IPC: F02K5/00
Filed: 1933-09-05
Abstract: 425,046. Two - stroke direct acting engines. STENNING, G. A., 63, Queen's Park Road, Brighton. Sept. 5, 1933, No. 24579. [Class 7 (ii)] [See also Group XXXIII] In propulsion means for aircraft, fluid under pressure is ejected from a jet driven in the direction of the issuing fluid so that a region of low pressure connected with the surrounding atmosphere is created within the craft. As shown, a fixed cam member in the head 2 of a cylinder 1, which is provided with a check-valve 6 controlling ports 5, actuates a valve 14 pivotally mounted on a piston 12 and closes, during explosion of a charge in the cylinder, the end of a hollow piston-rod 13. An inletvalve 8 actuated by known operating gear is provided and a pipe 10 communicates with this valve and a port in the cylinder adjacent the valve 6 and is also connected to a fuelsupply pipe 11. When explosion takes place the piston is forced to the left allowing the resulting gases to pass into the rod 13. When the piston reaches the end of its stroke, a cam member 17 on the plate 6 engages a cam member 18, Fig. 4a extending through the piston from the valve 14, to close the end of the piston rod ; subsequent movement of the piston to the right lifts the valve 6 and air thus admitted passes, during the outward stroke of the piston, through the pipe 10 and port of the valve 8. A second duplicate piston and cylinder is arranged opposite the first cylinder and the piston rods are connected by a rod 20, the connections being such that jets 21 are formed. The jets move in cylinders separated by a partition 30, the high and low pressure ends of the cylinders being appropriately connected to apertures in the external surfaces of the craft to effect propulsion. The jets may be moved over a curved path.

IPC: G01R11/02
Filed: 1928-08-28
Abstract: 297,456. Allgemeine Elektricitõts- Ges. Sept. 23, 1927, [Convention date]. Driving - arrangements. The humming noise produced in clocks and tariff apparatus driven by high speed synchronous motors is minimized by making the natural vibration frequency of the elements forming the oscillatable mechanical system less than the frequency of impact occuring between the teeth of the driving system. The invention is illustrated in connection with a toothed wheel z driven by a pinion R on the shaft A of the motor armature L. This shaft has a tendency to assume a vibratory bending movement in its bearings 3, 4, as indicated in Fig. 3, with a natural frequency. According to the invention, this frequency is made less than that of the tooth impacts by a suitable determination of the dimensions and weight of the armature disc and spindle with the result that the shaft runs quietly.

Title: Process and apparatus for sedimentation of solid impurities from liquids
IPC: C02F1/52
Filed: 1970-05-22
Abstract: 1287360 Sedimentation of solid particles from a suspension in liquid. SEPARA BRNO 22 May 1970 [22 May 1969] 24952/70 Heading BID A suspension of solid particles in liquid is separated into sludge and clarified liquid by multi-stage sedimentation of the solid particles in an apparatus comprising a shell 1 which has a floor sloping at two different acute angles, the shell being divided into compartments I to V by partitions 2', 3', which are parallel to the two floor portions, and each pair of partitions being associated with a baffle 10 which overlaps the lower part of partition 2' forming a channel 11 between adjacent compartments. The suspension to be treated is introduced into the uppermost compartment through inlet 19 and deaerating chamber 21; some of the larger particles sink into the first sump 15 while the suspension flows up the first compartment from the first settling area 16, a small proportion of clarified liquid overflows from the top of the compartment into channel 26 and then flows to receiver 25, but a substantial stream of suspension flows turbulently down through channel 11 into the next lower compartment where the sedimentation of further particles and separation of the liquid into two streams again take place. The sedimentation and liquid-division processes are repeated in compartments III to V. Clarified liquid flows from compartments II.. V, via overflows 34 and pipes 27, into receiver 25. The rate of flow of clarified liquid in pipes 27 is adjustable. Clarified liquid is withdrawn from the apparatus through outlet 8. The sludge collected in each sump 15 is discharged by a screw conveyor (or other mechanical means) 24. The sludge particles obtained from successive sumps are of diminishing size. The area of the outlet of each channel 11 is adjustable. Chemical coagulants may be supplied at the inlet of the channel 11. Each clarifying area 17 is provided with a partition 18; and the top compartment has a set of parallel partitions 9. The process may be applied to the treatment of domestic sewage water, also for sorting kaolin and China clay, grading gravel, and separating paper pulp from slime.

Filed: 1928-09-03
Abstract: 324,939. Wheeler, T. S., and Imperial Chemical Industries, Ltd. Sept. 3, 1928. Aromatic hydrocarbons. - Saturated hydrocarbons such as methane or ethane are decomposed by heat to produce aromatic hydrocarbons such as benzene which are removed from the residual gases followed by the removal of hydrogen, for instance by passing the gas over a material which acts upon hydrogen but not on the hydrocarbons, such as copper oxide at 250‹ C. In an example, methane is passed through a heated tube at 1000‹ C. at a high space velocity, the resulting gas being condensed to produce light oils and the hydrogen is then separated either by diffusion or by interaction with added carbon monoxide in presence of a nickel catalyst in known manner. Specifications 211,461 (as open to inspection under Sect. 91 of the Acts), and 264,845 are referred to. Reference has been directed by the Comptroller to Specification 316,126.

Abstract: 1279068 Caps for bottles AMERICAN FLANGE & MFG CO Inc 19 April 1971 [6 April 1970] 25255/71 Heading B8T A lightweight metal closure cap 1 is removed from a container by tearing a section along weakened score lines. In order to reduce the jerk caused by the application of the extra force required to finally separate the torn cap from the container, the lines at the final section of the tear are scored deeper than those at the beginning. A pair of score lines formed in the surface of the cap begin on the edge of skirt 4 on either side of pull member 7, cross the skirt and a curved juncture portion substantially parallel and extend across top panel 2, flaring outwardly at 10a to terminate at the opposite edge of the skirt. A pull portion of a first depth extends to point 14 on each score line after which a second greater score depth is maintained. A transitional portion of gradually increasing depth lies between the two and counteracts the increased force required at the flared portion. Since the final portion is weakest, very little extra force is required to finally remove the cap remnants from the bottle and the tearing action is substantially uniform throughout.
