In a modification the perhipery 29 Fig. 2 (not shown) is also secured to the air inlet plate by a metal bellows and during manufacture the annular space between the bellows and the chamber is filled with oil.
Patent GB-929226-A (GB)
Title: Encapsulation of lipophilic material
IPC: B01J13/10
Filed: 1959-11-26
Abstract: Finely divided lipophilic material is encapsulated by a process wherein there are brought together in the presence of the dispersed lipophilic material, aqueous solutions of an electrophoretically chargeable styrene-maleic acid copolymer and of an oppositely chargeable gelable colloid at a temperature above the gelation temperature of the colloid and at a pH at which the copolymer is electrophoretically charged and the colloid is oppositely (and preferably equally) charged and at which significant liquid-liquid phase separation of both the polymer and colloid occurs, thereby inducing encapsulation of the lipophilic material within a mantle of copolymer and colloid which may be set by cooling the mixture below the gelation temperature of the colloid.  Alternatively, the pH of the mixture may initially be outside the above-mentioned range and is subsequently brought within it and/or setting may be induced by the addition of a highly active carbonyl compound, e.g. formaldehyde, glyoxal, malonic acid dialdehyde, pyruvaldehyde, glyceraldehyde, diacetyl or methyl phenyl ketone or ferric chloride and tannic acid. Specified gelable colloids are gelatin, albumin, casein, deacetylated chitins, polyvinylpyrrolidone, styrene-polyvinylpyridine copolymer, triethanolamine-phthalic acid copolymer, polyamino acids, e.g. polylysine, polyornithine.  The styrene-maleic acid copolymers may be represented by the formula (-R-R1-)n wherein R represents lipophilic polymer units of which more than 70% are styrene residues and R1 represents hydrophilic polymer units of which more than 50% are maleic acid residues and the aqueous solutions thereof used in the process may contain organic liquids, e.g. lower alkanols, lower alkylene glycols and lower alkyl triols and solubilizing agents in particular polysaccharides, e.g. alginates, pectins, methyl- and carboxymethyl-cellulose and Irish moss derivatives.  The encapsulated product of the invention may be useful, by virtue of the nature of the lipophilic material or of material dissolved therein, as a fertilizer, pesticide, plant growth regulant, food additive (e.g. containing vitamins or fats), medicaments (especially delayed and sustained release oral medicaments), cosmetics and coating compositions useful in the manufacture of record paper, pressure-sensitive tapes and labels and magnetic information storage devices when the lipophilic material contains magnetic or magnetizable particles.  A specific example relates to the encapsulation of a Vitamin A oil in styrene-maleic acid copolymer. Specification 751,600 is referred to.

Filed: 1970-08-28
Abstract: 1278407 Data processing INTERNATIONAL BUSINESS MACHINES CORP 28 Aug 1970 [9 Sept 1969] 41427/70 Heading G4A A data processing system comprises a storage unit for storing programme instructions including programme analysis instructions, means for executing instructions, an analysis counter which counts instructions executed after a programme analysis instruction is executed, and programme interrupt means operable when a predetermined count is reached or upon the occurrence of each programme analysis instruction to store the status of the system. On either type of interrupt, and on error interrupt, the contents of the instruction register, instruction counter, analysis counter, programme status words, general purpose registers, indicators and time clock, are saved in the storage unit. The analysis instruction has a field which is loaded into the analysis counter, the counting being by decrementing to zero (or incrementing to capacity) at which interrupt occurs. The analysis instructions are used for de-bugging, e.g. by causing interrupt they can cause exit from an endlessly-repeating loop. After the programme has been run, the analysis instructions and saved analysis counter values can be printed out, a zero (or capacity) counter value indicating programme error at that position. The analysis instructions will be treated as nooperation instructions if a suitable manual (or programme) control is activated. The analysis counter may be displayed on the console where it will be available to the operator to permit adjustable setting, and may be incremented or decremented under manual or programme control.

Abstract: 1,031,463. Semi-conductor rectifier switching circuits. JOSEPH LUCAS (INDUSTRIES) Ltd. Nov. 2, 1962 [Nov. 22, 1961], No. 41733/61. Heading H3T. [Also in Division H2] An overload protective arrangement comprises a " gate-controlled switch " 5 and a resistor 7 in series with the load 6 to be protected, the switch 5 being a controlled rectifier having the additional property that the application of a pulse of reverse polarity to that of the triggering pulse switches off the rectifier. The gate of the switch 5 is connected to one terminal 3 of an A.C. supply through a diode 10 and to the other terminal 4 through parallel inductor 9 and resistance means 8. During alternate half-cycles, the switch 5 is non- conductive and energy is stored in the inductor 9. During the intervening half-cycles, the energy in the inductor 9 turns on the switch 5 which conducts. Should the current through the switch 5 exceed a predetermined magnitude, the cathode voltage rises to a value sufficient to turn off the switch 5. The resistance means 8 may be a resistor or a Zener diode. A second similar circuit 5a ... 10a is oppositely connected to obtain current flow through the load and protection on the half-cycles in which the switch 5 is non-conductive.

Title: Method of Manufacturing Semiconductor Devices.

Abstract: 1,197,759. Semi-conductor devices. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 13 Sept., 1967 [15 Sept.. 1966], No. 41733/67. Heading H1K. [Also in Division Cl] To remove selected parts of a silicon nitride layer on the surface of a semiconductor device, other parts of the layer are masked and the device is heated in an oxidizing atmosphere in the presence of lead oxide. This converts the exposed nitride into a mixed lead-silicon oxide which is removed by solution in hydrofluoric acid-in which the oxide is readily soluble and the nitride much less soluble. The mask may itself be an oxide, such as a mixture of silicon and aluminium oxides deposited by heating the device in the presence of specified organic compounds of silicon and aluminium in an oxidizing atmosphere. The apertures in this mask are produced by a photoetching technique in which the etchant is predominantly phosphoric acid. The heating in the presence of lead oxide is for 20 minutes at 700 C. with the lead oxide placed a few tenths of a millimeter from the masked nitride. The subsequent HF etch removes both the converted nitride and the masking oxide. In an alternative method, the nitride is masked by a metal, e.g. nickel, deposit provided with apertures by a photo-etching technique. In this case, however, the heating in the presence of lead oxide is for 5 minutes only; this produces total conversion of nitride to oxide at the edges of the apertures in the nickel but only partial conversion of the remainder of the exposed nitride. After the final HF etch therefore, only narrow slits in the nitrideabout 1 micron wide-are completely removed. These narrow slits may expose areas which are subsequently doped.

A universal joint between two shafts comprises an intermediate member 22 having slideways 23, 24 formed in its faces facing the respective shafts for slidably and pivotally receiving coupling elements connected to the shafts. As shown in Fig. 1 the coupling elements for the two shafts are similar and for shaft 21 comprise pins 35 on a coupling member 27 keyed to the shaft and carrying selfaligning bearings 37, 38 engaged in the slideway 23. Fig. 5 shows a similar universal joint, but the intermediate member 22 is formed with a central aperture 43 within which is disposed a supplementary intermediate member 45 of a supplementary universal joint similar to the main joint but 90 degrees out of phase therewith, the purpose of the supplementary joint being to reduce out-of-balance effects when the driving and driven shafts are misaligned. The supplementary coupling element 26a for one shaft is rigid with the main coupling element 26, but the supplementary coupling element for the other shaft is freely rotatable. Fig. 7 shows another way of reducing out-of-balance, in this ease the universal joint is as before but masses 60, 61 are freely slidable within the slideways and are supported by pairs of springs resting on retaining plates such as 65a in the slideways. In a modification of this arrangement two independently slidable masses are supported in each slideway.
