IPC: H01H37/60
Filed: 1953-09-01
Abstract: 751,483. Thermal switches. THOMPSON & CO. (SUNBURY), Ltd., R. E. Dec. 1, 1954 [Sept. 1, 1953], No. 24128/53. Class 38(5) A snap action device comprises a leaf spring divided by slots into tension and compression strips which are interconnected at each end, the spring being supported at one end and between the ends of the tension strips, the operating force being applied to the free end. As applied to a thermal switch associated with an immersion heater, the spring 4 has two tension strips 6, 7 and a central compression strip 5, the strips 6, 7 being deformed at 8 to bow the strip 5.

Title: Improvements relating to gas turbine engines
IPC: F02C6/00
Filed: 1947-09-01
Abstract: 628,366. Generating combustion products under pressure. MORDELL, D. L. Sept. 1, 1947, No. 24151. [Class 51 (i)] [Also in Group XXVI] In gas turbine plant having re-heat combustion chambers which are to be brought into use during the operation of the plant, fuel and high-pressure air are ignited in a shielded chamber from which a torch flame then issues into the re-heat combustion chamber to ignite the main fuel supply. The shielded chamber may contain a spark or glow plug, or spontaneous ignition may be secured by a selected fuel or by a sufficiently hot air supply. The latter may be taken from the delivery of the main combustion chamber. A re-heat chamber 17, Fig. 3, between turbine stages has a main fuel supply 29 and a torch flame burner 22. Fuel is injected at 27 and highpressure air passes through the perforations in the end of the burner. Gases passing to a propulsion jet are re-heated by fuel from an injector 48, Fig. 5, in a central air duct 49. A torch flame is provided from a chamber 51. The valves controlling the supply of air and fuel to the torch flames may be operated by solenoids arranged in parallel circuit with the spark or glow plug. Specification 618,760, [Group XXVI], is referred to in the Provisional Specification.
Patent GB-667134-A (GB)
Title: Purifying aliphatic alcohols by azeotropic distillation
Filed: 1949-09-20
Abstract: A mixture of aliphatic alcohols having 3 and 4 carbon atoms per molecule, containing acetals, carbonyl compounds and organic oxides as impurities, is separated by distillation into a fraction containing the alcohols normally boiling below 100 DEG C. and a fraction containing the remaining alcohols; and the two fractions are separately subjected to azeotropic distillation with methyl cyclohexane so as to obtain from each of the fractions an azeotropic mixture with methyl cyclohexane of the alcohols present in the fraction substantially free from impurities.  The process is particularly applicable to a crude mixture of n-propanol, and n-, sec., and iso-butanols obtained by the partial oxidation of butane or mixtures of propane and butane.  Preferably the initial distillation is conducted so as to obtain a fraction which boils from about 96 to 103 DEG C. and another fraction which boils from 103 to about 120 DEG C.  Methyl cyclohexane may be separated from the azeotropic mixtures by combining them and subjecting the bulk to distillation with methanol; the methanol forms an azeotropic mixture with the methyl cyclohexane which distils off, leaving behind the purified alcohols. The mixture of purified alcohols is then subjected to ordinary fractionation for the recovery of the individual alcohols.

The combined total of ingredients 2, 3, 4 and 5 should amount to at least 0.05 mols/litre unless acetate alone is employed in which case the amount of acetate must be 0.10-0.13 mols/litre. The body is preferably treated first in a heated solution of ingredients 1-6, and a second solution consisting of ingredients 7 - 9 then added. The process as described relates to the coating of silicon with nickel-gold. Other semi-conductive materials which may be coated are germanium, silicon-germanium, indium antimonide and lead sulphide.  If desired, an over-coating of silver may be applied.
Patent GB-242307-A (GB)
Abstract: 242,307. National Cash Register Co., (Assignees of Brand, S.). Feb. 2, 1924, [Convention date]. Transfer - mechanism for the totalizers of cash registers comprises an actuating rack 33 slidably mounted. on the differentially - moved member 31 and nor mally stopped onE step short of home position by a lever 43. When transfer takes place, this lever is tripped to allow the rack to partake of the full travel of the differential member. The rack is attached to the member by means of slots engaging pins 34 one of which also pivotally supports an arm 46 notched to take over a pin 49 projecting from an extension of the rack. The lever 43 pivoted at 44 tends to rock clockwise under the action of a spring 45 but is prevented by a pin 40 on an arm 39 fast on a shaft' 38. Normally these parts are positioned as shown and on the return of the differential member the surface 54 of the lever is met by the pin 49 so that the rack is stopped one step short of complete return. If transfer from the lower denomination is to take place the transfer tooth 36 rocks shaft 38 and so removes pin 40 from a shoulder in slot 42 and allows the lever 43 to rock clockwise. This removes obstruction t'o the pin 49 and the rack consequently continues with the differential member beyond the zero position to the home position. A roller 51 on arm 46 normally runs along a circular rail 52 and in non-transfer operations a recess 53 in this rail allows the arm 46 to rock counterclockwise to permit the relative motion between the member 31 and the rack. In transfer operations any such movement is prevented by a pin 56 on the lever 43 standing in the path of t'he end 55 of the arm 46. Restoration of the lever 43 when tripped is effected in the next operation of the machine by a pin projecting from the neighbouring driving element. Specifications 8119/15, 228,567, and 242,308 are referred to.

A wig comprises inner and outer layers of flexible plastic adhesively united together, the outer layer having spaced rows of apertures in which tufts of hair are mounted. Tufts of hair 21 in aluminium tubes 22 are received in spaced apertures 16, countersunk at 17, in the outer layer 7, the hair being secured by deforming the ends of the tubes as at 23. The outer layer 7 is bonded to the inner layer 6 by the action of a solvent, drain vents 12 from cupped recesses 8 in the inner layer and coinciding drain vents 18 in the outer layer being pierced through the assembled layers. In the marginal portions of the wig the thickness of the outer layer tapers towards the edge and smaller but more numerous hair receiving apertures 19 are interspaced with drain apertures 20 which coincide with vents 10 and 13 in the inner layer. The edges of the wig are without vents but are pricked to resemble skin pores and provide outlets for perspiration. The wig is secured to the shaved head by suction cups over the mastoid areas of the skull and a lifter is described to facilitate removal of the wig.
