Abstract: 712,625. Lighting fittings. GENERAL ELECTRIC CO., Ltd., and BEGGS, S. S. May 9, 1952 [May 10, 1951], No. 11071/51. Class 75 (2) A lighting fitting for uniformly illuminating an area, e.g. for use in irradiating plants, comprises a concave reflector or pair of concave reflectors arranged to reflect light from a source over an angle of 45 to 120 degrees in a plane, and an auxiliary reflector or reflectors positioned closer to the light source than the outer edge or edges of the concave reflector or reflectors so as to intercept, and re-direct within the desired angle, at least part of the light from the source outside the desired angle and not directed towards the concave reflector or reflectors. A concave reflector 12 is provided at each side of a tubular lamp 10 and is so shaped that rays 20, 22 from the lamp axis 11 are reflected as rays 20<SP>1</SP>, 221 which cross each other at the desired angle of lighting, e.g. 60 degrees. The lower edges of the reflectors 12 extend slightly below the horizontal plane through the axis 11, and for redirecting the rays such as 23 to 26, which are directed below the edges of the reflectors 12 outside the desired angle, two pairs of auxiliary reflectors 15, 16 are provided which produce reflected rays 23<SP>1</SP> to 26<SP>1</SP> within the desired angle. A flat or shallow V-shaped reflecting plate 14 may be provided across the aperture between the upper edges of the reflectors 12 and spaced from the latter to provide passages for the heated air. The visible light source may be replaced by a source of ultra-violet or infra-red radiation. The fitting may, alternatively, comprise a compact light source, and an annular concave reflector.

Abstract: 580,221. Riveting. FAIREY AVIATION CO., Ltd., and TIPS, E. O. June 20, 1944, No. 11726. [Class 83 (iv)] A device having a spring-loaded dolly to close the shank of a rivet by hammer blows applied to its head also has means for applying pressure of the plates &c. being riveted. A casing a, Fig. 2, has a nozzle b containing a hardened headed pin g terminating just short of the end c of the nozzle. A hammer e slides in the casing and is normally held in contact with the head h by a strong spring f confined by a screw cap d. The device is pressed against the shank of a rivet that forces back the pin g and hammer e until the nozzle b presses against and clamps the plates to be riveted. Rebound of the hammer e due to blows applied to the head of the rivet effects the closing of the shank. The nozzle may be screwed so that a number of the devices may be mounted in a jig plate for the simultaneous closing of a number of units, or for inserting in a tapped hole i, Fig. 3, in a block having a spring locating plunger m to engage an adjacent hole. In a modification for mounting on a tubular U-shaped frame p, Fig. 6, the hammer e i pivoted at s and held against the head h by a spring t adjustably loaded at v. Locating plungers such as m may be provided one on each side for working in . either direction, means being provided for holding the plunger, not required, in a retracted position.

The former compounds may be converted to the latter by subliming in a high vacuum or by treatment with mineral acids.  The latter may be converted to the former by dissolving in excess alcohol of the formula R11OH. The 2-alkoxy compounds may be prepared by the following methods: (1) reductive desulphurization of the corresponding 2-thiobarbituric acid or S-alkyl derivative thereof; (2) reacting the corresponding malondiamide with a formic acid ester in the presence of an alcohol R11OH; (3) reacting an N-formyl derivative of such a malondiamide with an alkali metal alkoxide in the presence of an alcohol R11OH; (4) reacting an ester of the corresponding malonic acid with formamidine in the presence of an alcohol R11OH.  In the examples: (1) 2-methoxy-5-(p-chlorophenyl)-5-ethyl hexahydropyrimidine-4,6-dione is prepared from a -(p-chlorophenyl)-a -ethylmalondiamide, ethyl formate and sodium methoxide.  The 5-(p-fluorophenyl)-5-ethyl-, 5-(m-chlorophenyl) - 5 - ethyl -, and 5 - (p - chlorophenyl) - 5-methyl-derivatives are similarly prepared; (2) 2 - methoxy - 5 - p - tolyl - 1 - methyl - 5 - ethylhexahydropyrimidine - 4,6 - dione is prepared by reducing 5-p-tolyl-1-methyl-5-ethyl-2-thiobarbituric acid with Raney nickel; (3) the product of (1) is sublimed to form 5-(p-chlorophenyl) - 5 - ethyltetrahydropyrimidine - 4,6 - dione which is dissolved in sec.-butanol to form 2 - sec. - butyloxy - 5 - (p - chlorophenyl) - 5 - ethylhexahydropyrimidine-4,6-dione.  a  - (p - Chlorophenyl) - a  - ethyl malondiamide, and other malondiamides, are prepared by hydrolysis of the corresponding cyanoacetamide.  5 - p - Tolyl - 1 - methyl - 5 - ethyl - 2 - thiobarbituric acid is prepared by reacting p-tolylethylmalonyl chloride and N-methylthiourea.

Abstract: 179,177. Besenne, G. Jan. 29, 1921, [Convention date]. Recording by distinctive marks.- A time - distance recorder for vehicles, applicable also to machine tools, comprises a recording- disc 38 mounted on a spindle 42 driven by clockwork disposed within a sleeve 37 secured to the back wall of the casing, and a combined spurwheel 45 and cam 44 rotating on the sleeve and driven from the vehicle.

Abstract: 914,802. Change-speed friction gear. ELECTRIC & MUSICAL INDUSTRIES Ltd. April 15, 1959 [April 16, 1958], No. 12045/58. Class 80 (2). [Also in Group XXXVIII] In a gramophone change-speed friction drive in which the friction disc 3 is engageable with a stepped driving spindle 1 and the turntable 2, the lateral and axial movements of the disc are imparted to a bracket arm 12, on which the disc is mounted, by a pair of cams integral with a rotary speed-selector 4. The latter has appropriate indicia 8 on its rim, and when one of them is visible in a cut-out in the base-plate 6 a pin 25 carried by a spring-loaded arm 24 in engagement with arm 12 engages one of a series of detent recesses 10 in the circumference of a circular cam-plate 9 secured to selector 4, thus allowing disc 3 to engage the spindle and turntable. Rotation of member 4 to change speed causes pin 25 to ride on the periphery of cam 9, rotating arm 24 about a pivot-pin 22 to disengage arm 12 from disc 3. The vertical position of disc 3 is determined by the setting of a heart-shaped cam-slot in the face of disc 9, which is engaged by a pin 20 carried by a vertically movable bracket 17 on which the arm 12 is mounted. In the arrangement shown in Fig. 3 the selector 4 is of conoidal form 30, on which a helical line 32 operates in conjunction with indicia 33 on base-plate 6.
