Classes 20(3) and 137  A windscreen of the kind having a viewing slit at eye level to enable the driver to have clear vision under all conditions. comprises a convex screen 1 as viewed from the front, made e.g. of transparent plastic and having 'a central viewing aperture 3 and a central concave depression 2 which is wider at the bottom than at the top and has its maximum depth at the lower edge of the aperture 3. The depression 2 guides the incident air, see arrows 4, upwards across the aperture 3 substantially in the plane of the screen, and along the inside of the upper rearwardly curved part 5 of the screen to mix with air flowing over the top rof the screen with the minimum of eddies. The provision of the depression 2 reduces the air flow round the sides of the screen and also gives the screen additional rigidity, however, if further rigidity is required corrugatons (such as 6) may be provided adjacent the edges of the screen, alternatively the edges may be folded back and welded to form a hollow beaded edge. A further form of stiffening comprises a tube 7 of metal, or plastic, which is slit down one side to fit over an edge of the screen where it is retained by cementing, or by welding. The windscreen may be formed as a single piece, or as shown, the upper part 5 may be separate and joined to the lower part by removable fixing means 8. In another form the upper and lower parts are joined by rubber strips of bobbin section. For a closed motor car the aperture 3 is preferably closable by means of a hinged or removable section, the air being guided rearwards adjacent the inside of the roof to escape through a ventilator at the rear of the passenger compartment.

The 2-stilbenyl-1,2,3-triazoles of the formula wherein R denotes hydrogen, a salt-forming cation, C 1-4  alkyl optionally substituted by non- chromophoric substituents, or cyclohexyl, M denotes hydrogen or a salt forming cation, and n is 1 or 2, are claimed per se. Specified non- chromophoric substituents are C 1-4  alkyl halogen, C 1-4  alkoxy, phenoxy, C 1-4  alkylmercapto, phenylmercapto, carboxyl or sulpho or, in the case of two adjacent substituents, a methylene dioxy, trimethylene or tetramethylene group, and specified salt-forming cations are alkali and alkaline earth metal ions, NH 4 <SP>+</SP> and amine salt ions. The reaction is suitably effected at 10-150 C. and specified solvents are dialkylamides of formic or phosphoric acid and tetraalkyl ureas wherein the alkyl groups contain up to 4 carbon atoms; the strongly basic alkali metal compound is preferably an alkali metal alcoholate. The acid starting materials may be obtained by reacting an aldehyde with an appropriate aniline derivative, and the product may be reacted subsequently in situ. Amine salts may be obtained by converting an alkali metal salt of the sulphonic acid into the sulphochloride, followed by saponification in the presence of the desired amine. Carboxylic esters of the Formula IV may be manufactured by a known manner, e.g. by converting the carboxylic acids into the carboxylic acid chlorides and reacting the latter with alcohols; the sulphonic group, which may also be chlorinated, remains unchanged during the esterification step and may be converted to an appropriate salt in the subsequent saponification reaction. The triazole starting materials may be obtained by diazotizing a p-toluidine compound, reacting the product with an appropriate aminonaphthalene or aminobenzenesulphonic acid, followed by cyclization of the product. The products of Formula IV may be used to optically brighten a variety of organic materials, or they may be incorporated in cleansing compositions.

Abstract: 502,042. Gas - filled electric incandescent lamps. SIEMENS ELECTRIC LAMPS & SUPPLIES, Ltd., and ALDINGTON, J. N. Sept. 13, 1937, No. 24851. [Class 39 (ii)] In a lamp wherein a coiled filament is mounted within a bulb of low thermal capacity and comparatively small dimensions, and the bulb contains mercury which has a vapour pressure above one atmosphere under full running conditions, the operating voltage of the lamp is comparatively low, e.g. 50 volts or under, and the greatest dimension of the filament is not substantially more than one half of the largest internal dimension of the bulb. An inert gas or gases may be included in the lamp filling. In order to avoid dead spaces the shape of the bulb is preferably isothermal with respect to the type of filament employed, and places where condensation is likely to occur, such as the ends of the bulb, may be metallized in known manner. In the example the bulb 1, which may be blown from quartz tubing, is substantially spherical, with an internal diameter of about 19 mm., and contains a coiledcoil filament of an overall length of about 8 mm. The bulb is filled with argon to a pressure of about 25 mm. of mercury, and contains a globule 10 of mercury sufficient to produce a vapour pressure.of about 25 atmospheres within a short time of switching on the lamp. The bulb 1 is supported within an outer jacket 2 by strips of metal 3 which are clamped around the necks of the bulb and project laterally from stout conducting wires 4, 42 to which they are welded. The jacket 2 is exhausted of air and may be filled with a gas having a low thermal conductivity, e.g. nitrogen. In a modification a tubular bulb contains a filament in the form of a single helical coil extending longitudinally thereof.

Abstract: 1,154,984. Sewing machines. TRUBENISED (GT. BRITAIN) Ltd. 31 May, 1968 [31 May, 1967], No. 25109/67. Heading D1G. A sewing machine having means for temporarily reversing the direction of sewing comprises a template, a roller adapted to roll along an edge of the template, a first member mounted for guided movement relative to the template, and a second member rotated with the roller, the arrangement being such that the second member when brought into engagement with the first member by forward movement of the roller relative to the template operates to 'move the first member in a direction which both causes the second member and the roller to move rearwardly relative to the template and retracts the first member out of the path of the second member, such retraction allowing renewed forward movement of the roller and second member. A roller 1, rigid with a pinion 3, rolls counterclockwise along the edge of a template 2 until pinion 3 meshes with a rack 5 projecting beyond said edge. Rack 5 is formed on a bar 4 slidable on template 2 against a guide surface 6 inclined rearwardly at an angle a to said template edge, a spring 8 normally biasing bar 4 against a stud 7. Continued rotation of roller 1 and pinion 3 thereby serves to drive bar 4 inwardly, and, owing to the rearward inclination of surface 6, this causes roller 1 to slip rearwardly along the template edge until bar 4 has been driven flush with said edge, when roller 1 assumes its forward movement.
