Title: Methods for the production of thermo-couples
IPC: G01K7/06
Filed: 1932-04-26
Abstract: 393,403. Thermo-electric batteries. JACKSON, L. MELLERSH-, 28, Southampton Buildings, London.-(Siemens- Planiawerke Akt.-Ges. fur Kohlefabrikate; 128, Herz bergstrasse, Lichtenberg, Berlin.) April 26, 1932, No. 11999. [Class 53.] The elements of a thermo-couple consist of different types of carbon or of different mixtures of carbon materials, one or both of the elements being graphited. One element may be made by graphiting a carbon material which is not easily graphited such as carbon black, or wood carbon, the other element being made of a material such as petrol coke, which is easily graphited. Binding materials which are not easily graphited are used for the first element, materials easily graphited being used as binders for the second element. The mixtures of carbonaceous materials and binders are heated in a furnace to the graphiting temperature. The thermo-couple is suitable for use at high temperatures, e.g. above 3000‹ C. The Figure shows a couple in which the elements are in the form of a rod b and tube a screwed together at the hot junction c. A silica, porcelain or zirconium oxide tube d separates the elements, the cold ends of which are coated with metal f, g to which the leads are attached. A gas space e is left between the elements at the hot end. The whole couple may be enclosed in a protective casing of ceramic material or carbon which may be spaced from the couple by ceramic bodies. In a modification the elements instead of being screwed together, are of conical shape and are wedged together at the hot junction. They may also be joined together by a cement that can be carbonized by heat. In another method the elements, having been shaped from the plastic mass, are joined together before being heated and converted into graphite. A burnt and an unburnt member may also be united by the burning process.

Title: Improvements in or relating to the manufacture of synthetic resins
IPC: C08L67/08
Filed: 1937-04-28
Abstract: Quick-drying resins producing flexible and lustrous coatings which will not crack when applied to flexible or semi-rigid surfaces are obtained by separating, by means of selective solvent extraction, a polyhydric alcohol-polybasic acid resin into fast and slow - drying portions and subsequently combining the fast-drying portion with a further amount of the original resin or with any proportion of the slow-drying portion separated from a different polyhydric alcohol-polybasic acid resin, or recombining the fast and slow-drying portions derived from any one resin in proportions different from those in which they are present in the original untreated resin.  The fast-drying portion may be obtained from a polybasic alcohol-polybasic acid resin modified with a monohydric alcohol or a fatty oil or a monobasic acid or with two or more of these compounds. When fatty oils are used these are preferably first subjected with the polyhydric alcohol to heat treatment in presence of a catalyst, i.e. litharge.  In examples: (1) a resin A is obtained by heating a mixture of soya bean oil and glycerol, with litharge as catalyst, to 220-225 DEG  C. for 1 1/2 hours and adding phthalic anhydride and continuing the heating for some six hours; a resin B is prepared by heating a mixture of phthalic anhydride, chinawood oil acids, glycerol and toluene, and finally adding butyl acetate and ethyl acetate; the reaction vessel is provided with a condenser and separator for the toluene, which is re-used; resins A and B are extracted with butyl alcohol and the slow-drying extract of A is mixed with the fast-drying extract of B in the proportions 1 to 1, 1 to 4, and 7 to 93 to give resins drying in 18 mins., 45 secs., and 20 secs. respectively, as compared with 60 mins. and 10 secs. for the separate extracts; (2) a resin obtained by heating linseed oil, chinawood oil, glycerol, litharge, and phthalic anhydride is dissolved in toluene and the slow-drying portion extracted with mineral spirit; resins of specified drying time are obtained by recombining the slow and fast drying portions in different proportions.  A drier-solution may be added to the resin compositions in an amount containing 0,05 per cent each of Co and Mn calculated on the drying-oil in the resin.  The resins may be used for glazing paper, cardboard, cellulose-derivative coated textiles; in producing high lustre finishes on wood, metal, plaster; as thermoplastic adhesives; as anchoring means for metal flake powders, pigments, flocks; as ingredients of heat-hardenable plastics and of cellulose nitrate or other cellulose-derivative lacquer.

Title: Improvements in change speed gearing
IPC: F16H61/02
Filed: 1924-05-20
Abstract: 238,602. Rowlands, P. O. May 20, 1924. Facilitating changing speed. - In change-speed gearing suitable for vehicles, auxiliary friction gearing is employed to bring gear and clutch teeth to similar speeds prior to engagement, such friction gearing being selected by the speed gear control and brought into action by the main clutch pedal. In the arrangement described with reference to Figs. 2 and 3, there is a driving-shaft 28, a driven shaft 2 with slidable gears 23, 24 upon it, and a lay shaft 3, and the auxiliary friction gearing 7, 8, 9, 10, 11, 12 is adapted to connect an extension 2a of the shaft 2 to the lay shaft so as to speed up the lay shaft gears by effort derived from the vehicle road wheels. The change gears 23, 24 are selected by axial movement of a hand-lever 22 and brought into mesh by subsequent pivotal movement of the same lever. The axial movement of the lever 22 through a linkage 20, 19 also serves to selectively move the set of friction gears 10, 11, 12. In changing speed, the main clutch is disengaged and the lever 22 is moved axially only. The clutch pedal 17<a> is then further depressed, which through a linkage 16, 15 brings the selected friction gears into action by lateral movement of a shaft 5. This lateral movement also brings a pair 7, 4 into engagement whereby the lay shaft 3 is driven to speed up the gear or clutch teeth, which are. then enmeshed by the pivotal movement of the lever 22. The main clutch is then let in, which disengaged the friction gearing. A four-speed arrangement is described. In a modification, conical friction stepby-step auxiliary gearing is employed.
