Abstract: 534,127. Photographic enlarging apparatus. KODAK, Ltd. Dec. 29, 1939, No. 33028. Convention date, Dec. 31, 1938. [Classes 98 (i) and 98 (ii)] A photographic enlarging apparatus comprises a fixed focus camera having a front tubular extension member carrying locating means for a detachable negative support comprising selectively an apertured plate member or a film holder, a clamping element for the support being movably mounted on the extension member and being adapted in one position to retain the apertured plate member and in another position to retain the film holder in position. In the form shown, the front 12 of a fixed-focus camera carries an integral tubular extension 15 with an apertured front plate on which may be positioned an apertured filmsupporting plate 21 forming one of a series having different sized apertures. Locating pegs 19 extend through holes 20 in the plate, and also engage the longitudinal edges of the film to position it. A flexible clip 56 may be secured to one edge of the plate for holding a singleimage section of film 54 as shown in Fig. 7. Alternatively, as shown in Fig. 5, a holder 59 carrying a positive transparency mounted between glasses such as that described in Specification 493,880, may be located between the pins 19 and against a stop 67. The clamping device consists in a U-form spring member 30 which is pivoted to lugs 34 on the extension 15, and to which is pivoted a frame 35 carrying an opal diffusing glass. When the member 30 is folded down and held by a spring latch 46, which engages lugs 48 the pivoted frame 35 clamps the film or film holder 59 in position. The pivots 36 of the frame are not in the centre line of its sides, so that by reversing it through 180 degrees it will engage either the film or the film holder. For making separation negatives from colour positives, a slide 70 carrying colour filters is' adjustable in the tubular extension to bring the desired filter in front of the lens.

Abstract: 366,569. Automatic exchange systems. STANDARD TELEPHONES & CABLES, Ltd., WRIGHT, E. P. G., HARTLEY, G. C., and REYNOLDS, W. J., Columbia House, Aldwych, London. Nov. 6, 1930, No. 33371. [Class 40 (iv).] In equipment for determining the number of apparatus units in use at a given time, the switches AS which give access in succession to the apparatus units are located in proximity to the units themselves and apart from the central recording position. The apparatus units are associated with a plurality of levels 1 .. 8 of the access switches, each level being divided into five groups of ten, and each of the eight wipers is multipled to five jacks into which a meter circuit MC may be plugged, the jack circuits being rendered operative in turn under the control of a marking level 9 of the access switch. The equipment is adapted for use with apparatus marked busy either by the absence of full battery potential or by the presence of ground potential. To commence an observation, pulse key PK, common start key CK, and start keys SK individual to particular access switches are operated. The pulse on key PK intermittently operates relays TS, P so that at each second pulse the switches AS are advanced one step. Relay S is operated initially by a pulse over CK and locked over off-normal level 10 until the switch returns home. When an idle apparatus unit denoted by full battery on the test wire is encountered, relay T operates disconnecting the meter M, but if a busy unit is encountered meter M operates from ground on the jack sleeve. For apparatus units marked busy by ground on the test wire, the ring of the associated jack is connected to battery, Fig. 2, relay T operating over this battery unless it is short-circuited by busy ground on the tip contact.

Title: Improvements in the absorption of nitrogen-oxide-containing gases mixed with oxygen or air
IPC: B01D53/56
Filed: 1931-12-02
Abstract: Gases containing nitrogen oxides admixed with oxygen or air are absorbed by means of solid ammonium bicarbonate.  The gases may be passed from below through vessels containing coarse crystals of ammonium bicarbonate, a concentrated solution of ammonium nitrate collecting at the bottom.  The solution also contains some ammonium bicarbonate and ammonia, and may be used for pretreating fresh nitrogen oxide gases.  The formation of free ammonia may be facilitated by heating the solid bicarbonate.  Carbon dioxide, admixed with any excess oxygen or nitrogen, escapes at the top of the vessel and may be used to precipitate ammonium bicarbonate from an ammoniacal solution.  The Specification as open to inspection under Sect. 91 (3) (a) is not restricted to the use of ammonium bicarbonate in the solid form.

Patent GB-749729-A (GB)
Title: Process for the preparation of lubricating greases
IPC: D03D15/12
Filed: 1953-12-03
Abstract: Lubricating grease is prepared by substantially completely dehydrating a mixture of a lubricating oil and one or more alkaline earth metal soaps of a hydroxy fatty acid by heating to below the solution temperature of the soap in the oil, and cooling the mixture to 210 DEG F. or below, the mixture being subjected to shearing at a rate of at least 25,000 reciprocal seconds during both the heating and cooling steps.  Performed soaps may be used, or the soap may be prepared in the lubricating oil by saponification of the corresponding acids or glycerides.  Acids referred to are hydroxy and dihydroxy stearic acids, hydroxy and dihydroxy palmitic acids, hydroxy myristic acids and hydroxy behenic acids, and the hydroxy acids produced by catalytic oxidation of hydrocarbon oils and waxes. The soap of the hydroxy fatty acid may also contain other soaps such as sodium soaps, e.g. sodium stearate and oleate and sodium 12- hydroxy stearate. Normal or basic soaps may be used.  Lubricating oils referred to are mineral and synthetic oils such as oils prepared, for example, by redistilling a gas oil or lubricating oil fraction over caustic soda, extracting the distillate with a solvent such as sulphur dioxide, and refining the raffinate with an absorbent. Esters of alimono- and dibasic acids, aliphatic esters, organic phosphates, phosphonates, organic silicates and silicones; examples specified are bis (2-ethylhexyl) sebacate, dibutyl phthalate, tetrakis (2-ethylhexyl) silicate, dioctyl phthalate, tributyl phosphate, trimethylene glycol polymers and copolymers of ethylene and propylene glycols.  The shearing may be effected by passing the grease through a colloid mill, a multiple roll mill such as a paint mill, or a homogenizing valve, or by forcing the grease through a screen by a high capacity pump.  Oxidation inhibitors such as aromatic amines, e.g. N, N1-(tetramethyldiamino-diphenylmethane, diphenylamine and phenyl alpha-naphthylamine; anticorrosion agents; and non-soap thickeners such as latex and "Paratac" (Registered Trade Mark) may be incorporated in the greases.

Title: Boron-containing compounds
Inventor: MILLER HENRY CARLES
IPC: C01B6/00
Filed: 1961-09-22
Abstract: The invention comprises the boron-containing acid H2B12H12 which is a white crystalline solid having per molecule two ionizable hydrogen atoms and a divalent anion B12H12.  The acid is soluble in water and oxygenated solvents and may be separated from such solutions in a form containing up to 4 moles of water or solvent of crystallization. The acid is prepared by contacting an aqueous or non-aqueous solution of a salt of the B12H12 anion (prepared as described in Specification 989,293) with a strong acid. For example, a methanol solution of Na2B12H12 is treated with hydrogen chloride or sulphuric acid, an aqueous solution of BaB12H12 with sulphuric acid, or an aqueous solution of (NH4)2B12H12 with hydrochloric acid. Alternatively, an aqueous solution of the salt is contacted with an acidic ion exchange resin, either by mechanical mixing or by passing the solution through a column of the ion exchanger; the resultant solution is evaporated to obtain the solid acid.  The acid has a pKa value at 25 DEG  C. of about 2 and a characteristic infra-red absorption spectrum.  It is useful as a sequestering agent for metals, e.g. to separate copper from gasoline or aqueous solutions, and for etching steel, rust removal, pickling, and scale removal.ALSO:Hydrocarbon substituents are introduced into the B12H12 anion of the acid H2B12H12\t (see Division C1) for example by reaction with propyl alcohol and propylene to obtain.  (H3O)2B12H10[CH(CH3)2]2 or by reaction with hexene to obtain the cyclohexyl substituted acid, the caesium salt of which is useful as a surface active agent.  Specification 989,293 is referred to.
