Title: Improvements relating to pulse transfer devices
Inventor: HOUNSFIELD GODFREY NEWBOLD
IPC: G11C19/04
Filed: 1957-04-30
Abstract: 893,355. Circuits employing bi-stable magnetic elements. ELECTRIC & MUSICAL INDUSTRIES Ltd. April 22, 1958 [April 30, 1957], No. 13799/57. Class 40 (9). [Also in Group XIX] A shift register employing, as shown, magnetic cores 1, 12 and in which pulse lengthening means enable the use of one core per bit, has turn-off pulses applied from bias source 15 to the transistor coupling amplifiers to cut them all off simultaneously. The pulse-lengthening means may consist of the RC network 6, 14, shown, or hole storage in the transistors may be utilized. Fig. 7 (not shown), illustrates a modification in which the output from core 1 is in opposition to that from a similar core which also receives the shift pulses and hence, if it stores a " 1," inhibits the transfer of a " 1 " from core 1 to the next core. Fig. 8 (not shown), illustrates the application of the turn-off pulse directly to the transistor base.

Title: Improvements in or relating to adhesives
Inventor: WEIGHALL JOSEPH GEORGE
IPC: C04B26/12
Filed: 1949-05-25
Abstract: An adhesive composition comprises between 70 and 90 per cent of a powdered mineral filler, between 5 and 12 per cent of a heat-hardenable phenol-aldehyde resin, a plastizer therefor, and between 0.05 and 5 per cent of a silicone, the percentages being by weight of the composition.  The phenolic resin may either be a resol formed, e.g. by reacting a phenol such as cresol with a molecular excess of formaldehyde in the presence of an alkaline catalyst, or a mixture of hexamethylenetetramine and a novolak formed, e.g. by reacting a phenol with less than an equimolecular amount of formaldehyde in the presence of an acidic catalyst. Mineral fillers specified are marble dust, calcite, lithopone and barium sulphate. The plasticizer may comprise a liquid such as dibutyl phthalate or other high boiling liquid, or a material which itself is resinous or a mixture of such liquid and resinous material, e.g. rosin, shellac or ester gum, or it may consist of or include a thermoplastic or thermosetting synthetic resin, or it may be a fatty oil combined with a hardenable synthetic resin, e.g. the oil may be combined with a portion of the heat-hardenable resin (or other synthetic resin) and the product may be incorporated with the adhesive or with the basic resin of the adhesive.  The plasticizer may be used in amount between 2 and 12 per cent by weight of the composition.  The silicones, preferably those having thermosetting properties, may be added at any stage of the manufacture of the adhesive or be added to the paste formed by mixing the adhesive composition with solvent.  In examples: (1) a resin made by dehydrating a mixture of a toluol solution of a silicone and a novolak obtained by refluxing phenol, aqueous formaldehyde and oxalic acid, was grouped and mixed with hexamethylenetetramine, calcite and colophony.  The adhesive was made into a paste by mixing the alcohol; (2) the novolak of example (1) was modified by refluxing with blown castor oil and sulphuric acid, and the resulting resin was ground and mixed with hexamethylenetetramine, lithopone and ground marble and finally made into a paste with alcohol and mixed with a toluol solution of a silicone; (3) a castor-oil modified novolak resin, a mixture of a novolak resin, and a silicone resin, hexamethylenetetramine and p ground marble were ground in a ball mill and the mixture was formed into a paste by mixing with a solution of dibutylphthalate in alcohol.  The adhesives are used for fixing moulded or metallic caps to electric lamp bulbs and radio valves.
Patent GB-327885-A (GB)
IPC: C01B25/30
Filed: 1929-05-06
Abstract: 327,885. Kali-Forschungs - Anstalt Ges. Nov. 19, 1928, [Convention date]. Potassium monophosphate is obtaiend by heating potassium chloride with an excess of phosphoric acid of over 30 per cent strength at about 130‹ C., until the chlorine is driven off as hydrochloric acid, this being accelerated by working under reduced pressure. The acid salt. KH2PO4.H3PO4 crystallizes on cooling, and after separation, is treated with sufficient potassium monophosphate solution or water to precipitate potassium monophosphate, and leave a supernatant liquor saturated with the acid and monophosphate. This liquor and the mother liquor from the crystallization of the acid salt are used, with a further addition of phosphoric acid, for the conversion of further quantities of potassium chloride. The precipitated monophosphate is treated with water, and the mother liquor therefrom is again used to decompose the acid salt. Alternatively, the hot solution from the reaction with phosphoric acid may be treated with sufficient potassium monophosphate solution or water to produce, after cooling to precipitate potassium monophosphate, a liquor corresponding in composition to the liquod obtained above in the first described method of splitting the acid salt.

Title: Lubricating greases
Inventor: CLOGG ALAN DAVID
Filed: 1955-05-16
Abstract: A process for preparing lubricating grease compositions comprises mixing to a grease consistency a complex ester with a grease-making proportion of amorphous silica or the reaction product thereof with an alcohol.  The complex esters comprise the reaction products of at least one polycarboxylic acid and at least one polyhydroxy alcohol and comprise the reaction products of at least two of the following: monohydric alcohols, polyhydric alcohols, glycols, polyglycols, monocarboxylic, dicarboxylic and other polycarboxylic acids including hydroxy acids.  The alcohols include aliphatic, ether, thio, and thio-ether alcohols and preferably contain a branched aliphatic chain, examples being 2-ethyl hexanol and branched nonanols such as oxo nonanols.  The acids are those containing up to 22 carbon atoms, examples being adipic, azelaic and sebacic acids.  The glycols include members of the alkylene and polyalkalene series.  The preferred complex esters have the structure alcohol residue-dibasic acid residue-polyglycol residue-dibasic acid residue-alcohol residue. The amorphous silicas have a particle size of 5-100 millimicrons, but may be sponge-like aggregates thereof of the order of 1000 millimicrons.  The silica/alcohol reaction products are obtained by the reaction of a C2-20 primary aliphatic alcohol with acidic groups on the surface of a silica areogel.  The complex esters forming the base oils may be blended with other organic compounds such as mono- and di-esters, glycol ethers, formals and polyformals.  Other optional ingredients are anti-oxidants such as phenyl alpha or beta naphthylamine, trialkyl phenols, diphenylamine or phenothiazine; corrosion inibitors such as sorbitan mono-oleate or zinc naphthenate; and oiliness agents such as metal soaps or esters of fatty acids, e.g. isopropyl oleate. In the example, a complex ester derived from sebacic acid, 2-ethyl hexanol and polyglycol of molecular weight 200 is thickened with amorphous silica having a particle size of 8-10 millimicrons and phenyl alpha naphthylamine and zinc naphthenate are incorporated in the grease.

Abstract: 465,432. Automatic control systems. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE. May 18, 1936, No. 14099. Convention date, May 18, 1935. [Class 38 (iv)] [Also in Group XL] Power &c. output.-A radio or like transmitter arrangement of the kind comprising at least two parallel-connected transmitter stages is provided with electro-mechanical relay or like means responsive differentially to the loads on the parallel-connected stages and adapted upon response to adjust the loads automatically to equality. In the example shown in Fig. 3, differences in voltage across the resistances R1, R2 in the anode leads to transmitters T1, T2 actuate the double-acting relay D which starts the reversible series motor C. Relays Fl, F2 have contacts which prevent simultaneous actuation in both directions. Coil H removes a brake before making the main contacts HC and two single relays may replace the relay D. The motor C, Fig. 2, rotates the internally toothed drum G through a worm LW, thus producing, through gears Z1, Z2, a difference in rotation of the shafts W1, W2 which control the aerial coupling to the two stages, thereby equalizing the load on these stages. Equalizing gearing A and a clutch CL are provided. With more than two stages equalizing arrangements may be provided between each pair of stages ; alternatively, each stage may be connected through an equalizing arrangement to a master stage which is uncontrolled.
