[Class 64(ii)] [Also in Group XX] The temperature of an object is controlled at a remote point by transferring heat from the object to a thermostat, or vice versa, by means of an evaporating and condensing liquid contained in a conduit having closed ends. As shown in Fig. 1 the apparatus comprises two interconnected closed vessels, the one 13 in contact with the furnace 10 whose temperature is to be measured, the other 14 in contact with a thermometer 15, the arrangement being such that changes of heat in the furnace 10 cause corresponding evaporation or condensation of the liquid in the vessel 13 with reciprocal condensation or evaporation in the vessel 14, the heat thus released or absorbed being indicated on the thermometer 15 which may be replaced by a thermostat. The levels of the two vessels 13, 14 are arranged so that condensed liquid returns to the vessel from which it is normally evaporated, thus, as shown, vessel 14 is higher than vessel 13. If however the temperature of the object 10 is normally below ambient temperature the vessel 14 is arranged to be lower than vessel 13. Alternatively the two vessels may be at the same level but so designed that an excess quantity of liquid in the one is returned to the other in either direction.

Abstract: Moulding compositions are made by separately mixing finely-divided keratin and cellulose with portions of a solution of amino-plast material, of the kind comprising urea-formaldehyde and/or melamine-formaldehyde, to form doughs, thoroughly mixing the doughs, and drying and grinding the resulting mixture.  The solutions to which the keratin and cellulose are added are preferably buffered to a pH of 7.0 to 7.3 and 7.3 to 7.5, respectively.

Abstract: 769,033. Electrical component assemblies. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd. June 28, 1955 [Sept. 22, 1954]; No. 27353/54. Class 40(5) An electrical-components assembly is made by the steps of embedding an electrical component in a synthetic resin to produce a plate-like form, mounting at least one other electrical component against the plate-like form, and applying a similar synthetic resin to mould the resultant assembly into a unitary structure. The Figures illustrate a filter assembly comprising silvered-mica capacitors 10, 11 and dust-cored inductors 20, 22. Before assembly the capacitors are separately embedded in cold-setting resin to form plates 14, 15, a plan view of plate 14 being shown in Fig. 3. The plate 14 carries eight hollow terminals 16 while the plate 15 is of identical shape but is provided with four countersunk holes 19, one at each corner only. To build up the assembly electrically-conducting spacing rods 17 are fitted through the corner holes of the plate 15 and are then covered with insulating sleeving 21. The inductors 20, 22 are placed upon the plate 15 and the plate 14 is arranged above the inductors with the rods 17 passing through the hollow terminals 16 at the corners of the plate 14, the plate 14 being pressed down to clamp the inductors 20, 22 and being retained in this position by suitably deforming the spacing rods 17. The leads of the lower capacitor 11 are wound round and soldered to the rods 17 at one side of the assembly, the leads from the capacitor 10 are soldered to the other two spacing rods, and the leads from the inductors 20, 22 are soldered to the intermediate hollow terminals 16. The assembly is then placed in a mould which is filled with cold-setting resin through the V-shaped notches in the upper plate 14, the resin being allowed to set thus resulting in a component assembly as illustrated in Fig. 4. A plurality of similar filter units, all of the same height, may be arranged in a metal container with their terminals all lying in the same plane and thus readily accessible for wiring between the units.

[Also in Division A3] A reticular film or sheet consisting of a "thermoplastic adhesive composition" is made by forming a pattern of spaced apart cuts in the film, the cuts extending therethrough, placing the film upon a supporting surface which is of such a nature it does not prevent movement of the film, heating the film to such an extent that the film material softens and shrinks away from the cuts, whereby the cuts widen to form apertures and the film acquires a reticulated structure. "Thermoplastic adhesive composition" is defined as a solvent-free adhesive composition which at normal room temperatures is in a solid condition in which it is substantially incapable of forming a strong bond with a solid surface but which can be softened and brought to a bond-forming condition by the application of heat, the composition returning to a solid condition on being allowed to cool, and the composition being capable of use in an adhesive bonding process in which the composition is heated to bondforming condition and allowed to cool. The supporting surface used in the formation of the reticulated film may be provided with a coating having "release characteristics" such as a coating of polytetrafluoroethylene or a silicone coating. The support may be a first workpiece which is to be bonded to a second workpiece by means of the web. (For details see Division A3). Preferably the pattern of spaced apart cuts is regular, all the cuts are of uniform length and parallel to one another and arranged in rows extending lengthwise of the cuts. The series of cuts in any one row is preferably staggered with respect to the series of cuts in the adjacent rows. The thermoplastic adhesive composition may comprise a condensation polymerization product of a mixture of 85 mol per cent dimerized linoleic acid and 15 mol per cent azelaic acid with a mixture of 85 mol per cent ethylene diamine and 15 mol per cent hexane diamine, the resulting polyamide containing material having a softening point (ball and ring) of 275 F. and a ball fall viscosity at 355 F.
