Title: Improvements in and relating to illuminating appliances
IPC: F21V5/00
Filed: 1928-04-03
Abstract: 298,447. Stephens, A. J., (Rolph, T. W.). April 3, 1928. Ceiling lamps.-A lens element 2 surrounding the light source 1 reduces the divergence of the light in vertical planes and an enclosing globe comprises a reflector 3 which directs the light vertically on to a bottom plate 4 for distribution. the upper part of the reflector having a light transmitting portion. The lens 2 of cup shape with a prismatic outer surface is held in place against a ledge 14 on the reflector by a, spring 11 and the bottom plate is fastened to the reflector by clips 12. On its inner surface the reflector 3 is of prismatic form giving downward reflection of typical rays C, D and the bottom plate may be constructed as described in Specification 258,482. [Class 75 (ii), Lamp chimneys &c.], to distribute the light uniformly as at C<1>, D'. Light directed upon the bottom of the cup as at G, H is refracted downwardly and distributed at G<1>, H<1>. Rays such as A, B, falling upon the upper portion of the globe are transmitted towards the ceiling while rays such as E, F falling upon reflecting prism between the points 6, 9 on the cup are directed towards the reflector 3 at such angles that they are transmitted upwardly by the prisms of the reflector and add to the illumination of the ceiling.
Patent GB-216112-A (GB)
IPC: G01G21/00
Filed: 1924-04-23
Abstract: 216,112. Krupp Akt.-Ges., F. May 17, 1923, [Convention date]. Automatic-feed weighers.-A gover. nor for controlling the time of operation of the automatic weighing devices of a mixing or other machine comprises a ratchet disc E, Fig. 1, provided with an adjustable stop e<7> which normally abuts against a stop c<2> on the frame C. The disc E is adapted to be rotated against the action of a spring G by an eccentric a<1> on a countershaft A, the connection being by means of a slidable rod B, a rocking lever D pivoted at c<1>, and pawls D<2>, D<4> pivoted respectively to the frame and to the lever. A bar J is supported by a roller H bearing on the inner surface of a ring E<4> fixed to the disc E, which rotates until an aperture e<5> in the ring comes into position beneath the roller H and allows the bar J to drop. In dropping, a pin i<3> projecting from the bar engages the lever D and moves it into an inoperative position. The governor may be adjusted to act after any predetermined time interval bv setting the stop e<7> in the correct hole e<6>. The lower end of the rod J is connected to a frame K, Fig. 3, which is adapted to rock on a shaft K<1>, but is normally held in a. raised position by brackets N<1> riveted to dropbars M<1>, each connected to the supply valve of one of a series of weighing receptacles S, and each supported by the engagement of a projection n<11> with a lever P. When the desired weight of material has passed into the receptacle S, the receptacle descends in the usual manner and depresses a lever R, thus allowing the lever P to rotate and release the corresponding bar M<1>. When all the receptacles are charged and the bars M, in their lowered position, the frame K is supported only by the bar J which in turn descends after the predetermined time interval has elapsed. As the frame K descends, a projection k<2> causes a clutch member u<2> on a rotating shaft u' to engage a worm V<5>, which drives a worm-wheel V rigidly mounted in a shaft V<1>. Cams on the shaft V' open the discharge valves of the receptacles S, and arms W<1> engage projections m<11> on the bars M<1> and raise them slightly above their normal positions before releasing them. While the bar J is raised above its normal position, a plate i<2> on the bar raises the pawls D<2>, D<4> and allows the disc E to return to its normal position under the action of the spring G. The continued rotation of the shaft V' causes an arm W<3> to engage a bow T and disengage the clutch. The machine is then in position to begin another cycle of operations.

Title: Method for packing dried and re-soaked fruit
IPC: A23B7/02
Filed: 1960-03-22
Abstract: Dried fruit which has been soaked in water is preserved by packing it in sealed transparent foil containers which are air- and water-tight and subjecting these to heat-treatment with non-ionizing radiation, e.g. infra-red rays or high-frequency radiation.  Preferably the fruit, e.g. dried prunes, apricots, sliced apples, &c., are soaked to a moisture content of 30 to 50% by weight and packed, together with a preservative, e.g. sodium benzoate, in thermostable foil bags, e.g. comprising a polyamide, a polyester or polyvinyl chloride, or regenerated cellulose film covered with one of these materials, which bags are then heat-sealed and exposed to a four to eight, preferably a five, minute heating by thermo elements placed above and below an endless gauze belt on which the bags are placed, the heating being of sufficient intensity for a temperature of at least 70 DEG  C. to be quickly reached at the centre of the fruit.  After heating the bags are cooled rapidly.
Patent GB-570427-A (GB)
Title: Improved manufacture of pure beta-picoline
Filed: 1943-06-24
Abstract: Pure b -picoline is recovered from basic oil mixtures containing b - and g -picoline by heating with a cyclic aldehyde at 130-180 DEG  C. in the presence of acetic anhydride, and separating the unchanged b -picoline from condensation products of the aldehyde with g -picoline, and with a -picoline and 2,6-butadine if these are present in the initial mixture.  The b -picoline catalyses the reaction of the aldehyde with the other methyl pyridines which proceeds substantially to completion. Where considerable amounts of 2,6-butidine are present, a preliminary separation thereof may be effected by treating with urea and separating the compound formed. Basic coal tar oil containing the b -picoline may be mixed with the aldehyde, preferably benzaldehyde or furfural, and acetic anhydride, generally in amounts equal to or slightly above the theoretical, and heated at 140-160 DEG  C. until reaction is complete. b -Picoline mixed with acetic acid can be separated by fractional distillation, acidified with sulphuric acid, and acetic acid distilled off.  The remaining acid sulphate is neutralized, e.g. with caustic soda, and b -picoline distilled.  Traces of aldehyde can be removed by resinifying and redistillation or the acid sulphate may be steam distilled prior to neutralization. Alternatively, the reaction mixture is steam distilled to distil off b -picoline, acetic acid and excess aldehyde, and the distillate acidified and worked up as above. The residual oil-water mixture from the steam distillation is allowed to stratify, and the aqueous layer worked up separately or with the distillate.  The solidified oil layer which may be a mixture of g -styryl-pyridine and 2,6-distyryl-pyridine when benzaldehyde is used may be crystallized from water.  In examples: (1) basic tar oil containing 40 per cent b -picoline, 45 g -picoline and 15 2,6-lutidine obtained from a picoline cut by removing part of the lutidine with urea, is heated for 4-5 hrs. at 170-180 DEG  C. with benzaldehyde and acetic anhydride, the product extracted with water, and b -picoline recovered from the aqueous layer; (2) a crude picoline cut wherein the percentages are 35, 40 and 25 respectively, is heated at 152 DEG  C. with excess of furfural and acetic anhydride, the product distilled off to 160 DEG  C., and b -picoline recovered from the distillate.  The purity of the b -picoline is determined from the melting point of the nicotinic acid obtained by oxidation.

Abstract: 299,837. Koppers Co., (Assignees of Shaw, J. A.). Nov. 2, 1927, [Convention date]. Ammoniacal liquor, separating and treating.-Tar acids such as phenol, cresol, &c. are removed from gas liquor, &c. by maintaining the liquid at a temperature just below its boiling point and blowing through it an inert gas such as air saturated with the volatile constituents of the liquid other than phenol. Tar acids are removed from the gas e.g. by sodium hydroxide and the gas recirculated. Gas liquor obtained from an ammonia still including a free ammonia still 2, a lime leg 4, a fixed ammonia still 3, and a dephlegmator 11, is sprayed over contact material 17 such as coke or tile in a tower 15 where it meets in counter-current an inert gas such as air. This carries off the tar acids to a washing tower 20 fed with caustic soda from a reservoir 24 and heated by a steam line 23, after which the gas is recirculated through the tower 15 by a blower 22. In a modification, the section in which the contact between the gas liquor and inert gas takes place is interposed between the free ammonia still and the lime leg, the gas cycle being substantially as before.
