Title: Apparatus for use in diagnosing dysmetric dyslexia
IPC: A61B5/16
Filed: 1974-07-15
Abstract: 1471199 Optical projectors J FRANK and H N LEVINSON 15 July 1974 [16 July 1973] 31261/74 Heading G2J An optical projector for use in detecting dyslexia in young children projects an image which moves across the screen at a rate which appears blurred to a dyslexic child but not to a normal child. As shown in Fig. 5, an overhead projector has independent drives for film strips 16, 18, strip 18 bearing words 17 and strip 16 bearing background images 19. One strip is moved and the other kept still while in both cases the child looks at the words 17 and signals if they appear to him to be blurred. As shown in Fig. 1, strip 16 moves between rollers 30, 32 having axles 34, 54 on which are mounted friction discs 38, 52. A pulley 56 driven by an electric motor (not shown) rotates a shaft 42 carrying driving discs 40, 50. A knob 44 moves shaft 42 longitudinally to engage discs 38 and 40 or 50 and 52 to provide forward or reverse transport of strip 16, the position of engagement determining the speed of the strip. Strip 18 has a similar, independent drive system operated by a knob 84. The projection head 24 is carried by an L-shaped rod 60 pivoted at 62 to the projector housing 26. The drive systems for the strips 16 and 18 are mounted on a body (102), Fig. 2 (not shown) which is rotatable relative to the housing 26.

Class 29 In an evaporator unit comprising a boxlike compartment cooled by evaporator tubes 18, 35, 39, 36 and 37 secured to the bottom, one side, rear, the other side and. top of the compartment, connected inseries and supplied with liquid refrigerant. by a restrictor tube 22 the end of which is formed as an injector in the first part of tube 18, refrigerant being recirculated  in the evaporators from a header 14 having a suction conduit 34, defrosting is effected by a single electric or other heater 24 clamped to the compartment bottom and in heat exchange with the first and last passes 25, 26 of the tube 18 so that vapour is condensed in and defrosts the tube 18 and the tubes 35, 39, 36 and 37 respectively. A liquid seal 21 is formed between the down pipe 20 from header 14 and the tube 18. Defrosting is terminated by a thermal element 52 and the tubes are disposed as shown to ensure adequate heating of the whole box, the spacing of the passes of the tube 18 being closer than that of the other tubes because more frost forms on the bottom. The front edges of the top and bottom of the box are folded over the front passes of the tubes 37, 18 respectively. The bottom is corrugated between the passes of tube 18 and defrost water from the compartment passes through apertures in the corrugations to fall on an inclined tray for disposal. The top of the box inclines rearwardly so that refrigerant will not collect therein. Specification 701,778 is referred to.

The preferred catalyst is a member of the platinum group, and the preferred acid medium is a strong mineral acid Solvents mentioned are glacial acetic acid, methyl alcohol and ethyl alcohol.  In examples: (1) The oxyketone C19H30O2 made from epidihydrocholesterol as described in Specification 435,563 is hydrogenated in glacial acetic acid solution in the presence of sulphuric acid and platinum oxide.  The diacetate is prepared by heating with acetic anhydride in the presence of pyridine.  (2) The same oxyketone as used in example (1) is hydrogenated under the same conditions except that alcohol is substituted for glacial acetic acid as the solvent.  (3) The acetate of the hydroxy ketone of example (1) is treated as described in example (2).  The benzoate may also be p  treated in the same way. (4) The mono-succinic ester of the hydroxy ketone of example (1) is hydrogenated in dioxane solution in the presence of sulphuric acid and platinum oxide.

Abstract: 1314620 Deposition of organic resin P P G INDUSTRIES INC 30 Dec 1970 [2 Jan 1970] 61835/70 Heading C7B In a method of coating an electrode with an organic material from an electrolyte containing an ionically solubilized synthetic organic resin, the electrode is first primed with a porous film of organic resin. The solubilized resin is preferably a base solubilized polycarboxylic acid resin. The primer film is produced by mechanically applying to the article a composition comprising a film-forming material containing a gelable polymer, and a solvent mixture for the film-forming material. The solvent mixture contains two mixable liquids one of which is a non-solvent for the polymer and has a lower volatility than the other liquid. When the solvent mixture is evaporated an open-celled resinous film is consequently formed. The film has a thickness of up to 5 mil. and is at least 10% vol. void having a Kubelka-Munk scattering coefficient of greater than 0À5 reciprocal mil at 5600 Angstom. Dyes or corrosion inhibiters may also be included in the film. Suitable gelable polymers for the primer film include, cellulose derivatives, acrylic resins, polyolefins, nylon, polycarbonates, polystyrene and numerous vinyl monomers and polymers.
