Abstract: ABSTRACT OF THE DISCLOSURE         A light-sensitive mixture is disclosed which contains a water-insoluble, aqueous-alkali-soluble binder, a light-sensitive o- or q-quinone-diazide or a mixture of a) a compound which generates or splits off an acid on exposure to light and b) a compound having at least one C-O-C group which can be cleaved by acid, and a phenol compound having 1 to 3 benzene nuclei which are mutually linked by single bonds, carbonyl groups, ether groups, thioether groups or optionally substituted methylene groups, and having at least one phenolic hydroxyl group and at least two substituents of the formula -CH2OR, in which R is hydrogen or a lower alkyl or acyl group.  The mixture is used for the preparation of light-sensitive copying material, pre-ferably for the preparation of planographic printing forms. The addition of the phenolic compound has the effect that the developed printing forms  can be baked at lower temperatures than hitherto in order to extend the printing run.

Abstract: ABSTRACT OF THE DISCLOSURE     The present invention relates to a stereo-scopic viewer which comprises optical elements per-mitting simultaneous examination, through two eyepieces, of two successive panoramic images in a film of pano-ramic exposures, the elements defining an optical path between each of the two images and its relevant eye-piece, and control elements for displacing one of the two images received by the observer in relation to the other; the optical elements comprise, for each optical path, on the one hand, a set of mirrors providing an odd number of reflections and, on the other hand, a total-reflection prism, preferably a right prism, the two prisms having, as a base, an isosceles triangle; the faces of the two prisms corresponding to the third side of the base, upon which total reflection is effected, are arranged substantially perpendicularly to the plane of the film to be examined and form between them an angle of about 90°, one of the faces running sub-stantially parallel with the longitudinal axis of the film to be examined.

Abstract: PROCESS FOR PRODUCING A HIGH-PURITY MALTOSE                 Abstract of the Disclosure An invention providing a process for producing a high purity maltose is disclosed.    More precisely,  the invention relates to a process for producing a high-purity maltose, comprising applying a material starch sugar solution with a maltose content of at least 70 % to a column packed with a strongly-acidic cation exchange resin of alkali metal- or alkaline earth metal-form; fractionating by charging thereto water the solution into HIGH-DEXTRIN FRACTION, HIGH-DEXTRIN-MALTOSE  FRACTION,  HIGH-MALTOSE  FRACTION,  HIGH-MALTOSE-GLUCOSE FRACTION,  and HIGH-GLUCOSE FRACTION,  in  the givn order; and recovering the HIGH-MALTOSE FRACTION.    In comparison with any conventional processes  for pro-ducing  a high-purity maltose with  the use  of  ion  exchange resin, the practise of the invention does constantly provide a fraction with a maltose content of 93 % or higher, and enable industrial-scale  production  of  a  high-purity  maltose  much easier at lower-cost.

Abstract: Abstract of the Disclosure A marine block employs a sheave which is rotatively mounted on an axle supported between a pair of spaced-apart cheek plates.  One or more ball bearing units are provided between the axle and the sheave, each unit containing a circular array of ball bearings which engage in circular races which are disposed radially outward from the axis of the axle.  Relatively large parts are formed in the cheek plates which are located directly opposite the bearing units whereby a water stream directed through the ports at one side of the block can penetrate around and between the exposed ball bearings and their races and scrub those surfaces free of dirt and film.  In a preferred block embodiment, clearance spaces exist radially inboard of the sheave between the bearing units and between the sheave and the cheek plates so that water can travel directly through the block and between the sheave and the cheek plates to further facilitate cleaning the block.

Abstract: SNAP ACTING SWITCH FOR THERMOSTATS OR THE LIKE   ABSTRACT OF THE DISCLOSURE          A snap acting switch structure for thermostats or the like is disclosed in which the switch's movable contact is supported on a pair of arms the first of which is placed in compression and the second of which is placed in tension by a bistable spring system. The first arm is formed of relatively thin metal providing deep flanges to cause the arm to act as a rigid beam pivoted at one end.  The two arms are welded together in face-to-face adjacency and the actuating force applied to the switch is applied substantially at the joint between the arms.  Therefore, there are no substantial bending forces applied to the first arm, and the switch effi-ciently produces good wiping between the contacts and suffi-cient shear forces to break welds which may occur therebe-tween.  The operating temperature differential is established for a given contact gap value by selecting the position of a calibration screw along the length of one leg of the snap spring system so that it cooperates with the stiffness of such leg to control the position of the joint between the snap spring legs to cause proper temperature differential.

Abstract: ABSTRACT           Process and apparatus for dissociating hydrogen atoms from a water molecule by electrical force.  Particularly, the separation of the hydrogen and oxygen atoms from the water molecule by the application of a non-regulated, non-filtered, low-power, direct current voltage electrical potential applied to two non-oxidizing similar metal plates having water passing therebetween.  The direct current voltage may be continuous, but the action can be enhanced by pulsing the non-regulated and non-filtered direct current voltage.  The apparatus comprises various constructional configurations and alternative embodiments for segregating the generated hydrogen gas from the oxygen gas.  The water need not be pure and may contain contaminants.  The release of the hydrogen and oxygen atoms causes the contaminants to fall away, thereby enabling the system to be utilized in a liquid slurry removal system.  Alternatively, the recombining of the hydrogen and oxygen would give pure water.

Abstract: PROCESS FOR MAKING CALCIUMMONOHYDROGEN PHOSPHATE DIHYDRATE      ABSTRACT OF THE DISCLOSURE    The disclosure relates to a process for making calcium-monohydrogen phosphate dihydrate with a high degree of white-ness from pure phosphoric acid and naturally occurring cal-cium carbonates. More particularly, a fine-particulate cal-cium carbonates is suspended in water and the suspension is mixed at temperatures between 0 and 60°C with phosphoric acid so as to establish a Ca/P-ratio of 0.20 up to 0.57. The phosphoric acid is added in quantities per unit time prevent--ing the resulting mixture from foaming over. Next, solid matter constituents are separated from the mixture, after CO2 has ceased to evolve, with the resultant formation of a clear colorless acid solution. This solution and an aqueous suspen-sion or solution of pure alkali metal and/or alkaline earth metal carbonates and/or hydroxides, are jointly in-troduced into a reaction zone at a reaction temperature of 20 to 45°C so as to establish a pH-value initially of 2.0 to 5.0 and then, towards the end of the reaction, of 6.0 to 8Ø Finally, the reaction product is filtered off, washed out, and dried in known fashion.

A neck portion is provided at a discharging end of the cartridge.  Plural séparate passageways extend through the neck portion, each passageway opening into a separate respec-live chamber.  Structure is provided for controlling the flow of the fluid compositions through the respective passageways, for preventing run-on of the fluid compositions through the respective passageways due to decompression of the fluid compositions upon removal of an extruding pressure, and thereby for preventing dispensing of the fluid compositions through the respective passageways in proportional ratios other than a desired predetermined proportional ratio.  Such structure includes a valve member having therethrough plural passage portions.  The valve member is mounted within the neck portion for movement with respect thereto between an open position, whereat the passage portions are aligned with respective of the passageways, thereby permitting extrusion through the passageways of the fluid compositions, and a closed position, whereat the passage portions are out of alignment with the respective passageways and the passageways are blocked by the valve member, thereby preventing any passage of the fluid compositions through the passageways.
