Abstract: 1,157,411. Measuring temperature of power cables, electrically. ANACONDA WIRE & CABLE CO. June 13, 1967, [Sept. 20, 1966], No. 27249/67. Heading G1N. [Also in Division H1] To permit measurement of the average temperature of a power cable conductor, a pilot wire 10 Fig. 1 is embedded in the conductor 11 along the axis thereof, during manufacture of the cable. The wire and conductor are connected together at one end remote from a D.C. measuring bridge apparatus to which the other ends of the wire and conductor are connected, the wire and conductor thereby being connected in series and forming one arm of the bridge. The bridge unbalance voltage is a measure of temperature above a reference temperature at which the meter is nulled. The D.C. source includes a full wave rectifier 23 and filter L25, C26 supplied with A.C. from a transformer secondary winding 24, the primary winding being the conductor 11. A voltage regulator (not shown) may be connected to the rectifier to provide a constant voltage input to the bridge. A capacitor 17 is connected between the pilot wire 10 and conductor 11 to eliminate A.C. inductively produced, and a surge protection capacitor C34 is connected across meter 18 of the bridge. The indicating meter and measuring bridge are mounted in a housing formed in an extension of a pothead insulator 28 Fig. 2 which terminates the conductor 11. The housing may be aluminium, and the edges thereof may be round to reduce corona discharge. Additionally corona prevention rings 31, 32 may be provided. An indicator window 33 is preferably of electrically conductive glass. Magnetic shielding from fields generated by conductor current may be provided in the form of a laminated iron casing (not shown) around three sides of the apparatus. Alternatively, the D.C. may be provided by a constant voltage battery, or the rectifier current may be derived from capacitive current between the pothead and earth Fig. 3 (not shown), since the power cable may operate at 345 kV. The temperature may additionally be remotely monitored by connecting the bridge output to modulate a carrier signal and transmitting over a telephone line, for example. The pilot wire is of the same material as the cable conductor.

Title: Improved process for the preparation of esters of aromatic di-carboxylic acids, and esters so produced
IPC: C07C69/82
Filed: 1953-10-06
Abstract: Diesters of low-boiling alcohols and aromatic dicarboxylic acids are made by esterifying the desired acid or acids with mono- or polyhydric high-boiling alcohols or mixtures thereof and subjecting the product to ester interchange with the desired low-boiling alcohol in the presence of alkaline or acid ester interchange catalysts. Low-boiling alcohols are defined as methyl, ethyl and propyl alcohol. High-boiling alcohols are defined as monohydric alcohols of 4 or more carbon atoms, e.g. n-butyl, -hexyl, -heptyl and -octyl alcohol and polyhydric alcohols such as glycols or glycerol.  Mixtures of high-boiling alcohols may be used.  Tere- and iso-phthalic acids are specified. Solubility increasing substances such as butyrolactone may be present.  Water, added before, or obtained in the reaction may be removed by azeotropic distillation with the mono- or poly-hydric alcohols.  The initial esterification is effected in conventional fashion.  Alkaline ester interchange catalysts mentioned are alkylates, e.g. a methylate, and alcoholic solutions of hydroxides the reaction being effected at pH8-10 and -10 DEG  C.-+80 DEG  C. Temperatures are generally higher when acid ester interchange catalysts are used and the desired ester is soluble in the reaction product so that the process has to be repeated preferably with the addition of fresh quantities of high boiling ester and the removal of a part of the residue, from which acid and high boiling alcohol may be recovered.  Terephthalic acid containing isophthalic acid as impurity may be esterified with methanol and the diesters of each acid separately obtained since that of the former precipitates from the reaction product at about 30 DEG  C., whereas that of the latter precipitates only on cooling to a lower temperature, e.g. 0 DEG  to 10 DEG  C.  Examples are provided illustrating the preparation of dimethyl terephthalate by the methods given above.

Title: A new or improved process for the production of dolls and other toys
Inventor: SUTTON ERIC ALLAN
IPC: A63H9/00
Filed: 1950-11-10
Abstract: A doll or other toy or part thereof in the form of a hollow body filled with soft material such as cotton-wool or kapok is made as follows:-Into a hollow mould of internal configuration corresponding to the external configuration of the toy or part thereof, e.g. a doll's head, is poured a plasticized polyvinyl chloride resin.  A thin layer of the resin next to the mould surface is then gelled, as by heat, to form the hollow body.  The ungelled resin is then drained off, and the gelled hollow body is heated to convert it into a solid elastomer.  The hollow body is then removed from the mould and filled with cotton-wool &c. and the filling opening is closed to retain the filling.  The mould used may be in two separable parts or in one piece; if it is in one piece the hollow body is removed therefrom by first deforming the body and then withdrawing it through the filling opening of the mould.  As described, a two-part mould is first heated to 160 DEG C., then the resin is poured in, then the excess is removed leaving a layer one sixty-fourth of an inch thick, and finally the layer is hardened at 160 DEG C. for 20-30 minutes.  The neck opening in a doll's head may be closed by stretching it over a disc provided on the end of a doll's trunk.

Title: Improvements in and relating to hydraulic brakes
IPC: B60T11/224
Filed: 1930-09-15
Abstract: 356,491. Fluid-pressure brakes TEVES MASCHINEN-UND-ARMATURENFABRIK GES., A., 23, Gustavsburgstrasse, Frankfort-on-Main, Germany. Sept. 15, 1930, No. 27554. Convention date, July 4. [Class 103 (i).] An hydraulic brake system comprises a large and a small piston for taking up play and applying the brakes respectively and a valve rendering the large piston inoperative during the actual applications of the brakes, which valve is opened by a control piston when the requisite fluid pressure for applying the brakes operates on this piston. The large piston 1 and the small piston 2 are rigidly connected by a rod 3 and are contained in cylinders 4, 5 constituting a single casting. When operated by a lever 8 fluid is rapidly forced by the piston 1 through grooves 25 in the piston 2 into the conduit 9 to the brake shoe operating cylinder 10. Fluid pressure is also exerted in conduits 13, 14 connected to cylinders 4, 5 respectively, and leading to bores 17, 18 at either end of a housing 15. Pressure is thus exerted on a valve 19 and a piston 22 contained in these bores respectively but the valve is maintained closed by a spring 31 until the brake shoes 12 engage the brake drum when the consequent increase of pressure in the pipe 14 moves the piston 22, the area of which is larger than that of the valve 19, and opens the valve 19, to release fluid from the cylinder 4 through conduits 13, 32 to the reservoir 7 in which the cylinders 4, 5 are contained. The system is filled with fluid by a pumping action of the pistons 1, 2 and passages 28, 29 make up fluid losses occurring in the system when the pistons are in the " off" position. In a modification the valve 42 is contained in the large piston 36 and is operated by the rod 37 of the small piston 38. The rod 37 slides in the rod of the large piston 36. A pin 44 passes through the rod of the piston 36 and through a slot 45 in the rod 37. The fluid in the cylinder 39 is released through apertures 52 past the valve 42 and through passages 53 to the reservoir in which the cylinder is contained.
