Filed: 1940-04-30
Abstract: 537,167. Valve generating circuits. STANDARD TELEPHONES & CABLES, Ltd. April 30, 1940, No. 7798. Convention date, May 3, 1939. [Class 40 (v)] In a crystal-controlled oscillator having a trimming impedance, e.g. condenser Cl, for slightly changing the frequency generated, and additional impedance, e.g. an inductance L1 which may be shunted by a condenser C2, is so dimensioned that variation of the trimming impedance results in a linear percentage change of the frequency generated, as indicated upon the dial S. A condenser C3 in parallel with Cl serves to adjust the zero of the dial at the desired nominal frequency. Alternatively, the inductance L1 may be in series with the condenser Cl. The invention is particularly useful for ultra-high frequency generators.

Title: Trimeric alpha methyl para methyl styrene and method of making the same
IPC: C07C2/02
Filed: 1946-03-15
Abstract: Trimeric a -methyl p-methyl styrene is prepared by heating a mixture of the monomer, and an activated bleaching earth such as fuller's earth or floridin, at a temperature of 37-43 DEG  C.  The earth may be activated by heating at above 200-400 DEG  C. for 2-5 hrs.  The ratio by weight of monomer to catalyst is generally between 97 : 3 and 90 : 10, preferably 96 : 4 and 93 : 7.  The catalyst in powder form is added slowly to the heated monomer with continuous agitation which is further continued, generally for 3-4 hrs., until reaction is complete, as shown by the index of refraction.  The product is filtered and purified by distillation. It is of use as the liquid medium in thermometers and thermostats, as an electrical insulating material, and as a plasticizer for resins such as polyvinyl acetal, acrylic and dihydronaphthalene resins, cyclized rubber, benzyl and ethyl cellulose, styrene polymers and rubbery butadiene copolymers with acrylonitrile or styrene.

Title: Copolymerising mono-epoxides with tetrahydrofurane
IPC: C08G18/48
Filed: 1958-03-14
Abstract: A monoepoxide is copolymerized with tetrahydrofurane in the presence of a compound having one or more reactive hydrogen atoms and, as catalyst, an acid-activated natural or synthetic bleaching earth. Specified epoxides are ethylene, propylene, butylene, amylene, styrene and phenoxypropene oxides and epichlorhydrin. Suitable bleaching earths are natural or synthetic montmorillonite and kaolinite, e.g. as sold under the name "Tonsil".  The activating acid is generally a mineral acid such as sulphuric or hydrochloric acid. By "compounds having reactive hydrogen atoms" is meant any compound which gives a positive Zerewitinoff test.  Examples are mono- and poly-hydric alcohols, saturated and unsaturated organic acids, mercaptans, phenols, acid imides and enolic compounds. Polymerization is effected at room temperatures and diluents may be present, e.g. hydrocarbons, chloro-hydrocarbons, dioxane, and a liquid copolymer prepared from a previous polymerization.  Elevated pressure is preferably employed.  The products have molecular weights of about 300 to 5,000 or higher.  The catalyst can be removed by mechanical or filtering means.  Examples are given, in one of which, Example 7, propylene oxide and tetrahydrofurane are copolymerized in the presence of methacrylic acid and the unsaturated product is said to be polymerizable, e.g. with olefines.  The polyglycol ethers are also useful starting materials for other plastic materials, e.g. polyurethanes, and for lubricants and fuel additives.

Title: Method of finishing fabrics, especially woollen fabrics
IPC: D06M11/05
Filed: 1950-04-05
Abstract: 678,585. Finishing fabrics. KOSTRING, F. April 5, 1950 [April 5, 1949], No. 8618/50. Class 42 (i). In a method of finishing fabric, especially woollen fabric, a length of fabric is smoothed, after wet dressing or moistening if dry, by being passed while maintained in the damp state over one or more smooth heated surfaces, then passed without tension over a heated metal surface of large area in order to dry it and achieve a certain smoothing and glazing effect, then damped with the application of heat and moisture, then brought into a freezing chamber and freed from tension, and finally freed from excess moisture and flat-pressed under light pressure. In the first treatment stage the fabric may be passed between a moistened felt wrapper and a rotating heated metal cylinder, and over the latter. A part of the excess moisture may then be removed by suction, and the fabric passed without tension around a large heated decatizing drum against which it is pressed by a felt wrapper and which imparts the glazing effect. The fabric may now be sheared and fluffed up and then passed over a steaming box in front of and behind which are atomizer nozzles which blow a fine mist of water against the moving fabric; or the fabric may be guided between damp felt and a heated rotating drum. The moistened fabric is then put into the freezing chamber, preferably at a temperature of - 1 ‹ to - 200 C. After freezing, the excess moisture may be removed by passing the fabric, with the aid of a wrapper, around heated metal surfaces during or after which treatment it is subjected to moist air. The final treatment may be effected between press-boards successively in hot chambers at about 70 C., and cold chambers at slightly over 0‹ C.

Patent GB-472287-A (GB)
Title: An improved arrangement for the automatic protection of railway sections by means of axle counters
IPC: B61L1/16
Filed: 1936-03-23
Abstract: 472,287. Railway signalling systems. VEREINIGTE EISENBAHN - SIGNALWERKE GES. March 23, 1936, No. 8675. Convention date, Feb. 13. Addition to 424,909. [Class 105] The signal control system described in the parent Specification is arranged so that the track contact 50, by which the danger signal is given independently of the axle-counting mechanism, lies ahead of the contact bv which the counting-in is commenced. Entry of a train operates the axle-counting mechanism 25, 26 whereby a change - over contact 27 deenergizes a relay 14 which may be a signaloperating relay or a signal-lever lock magnet. When a track contact 50 a little way ahead is opened, a stick relay 10 is de-energized and its contact 11 opens another point in the circuit for energizing the signal relay 14. If, therefore, the axle-counter contact 27 failed to change over, the signal relay 14 would nevertheless be independently de-energized by the opening of contact 11. The contact 27 when in the changed-over position closes a pick-up circuit for the stick relay 10. A shunting train on backing out of the section will allow the track contact 50 to close finally prior to the axlecounting mechanism being restored to the zero position and thus the stick relay 10 will be picked up since the contact 27 will still be in the non-zero position when the contact 50 is finally closed. The signal relay 14 is therefore energized when the shunting train has left the section. With the arrangement shown in the parent Specification the relay 14 would remain de-energized to give a danger signal after the shunting train had left. The axle-counting apparatus described in Specification 372,436 is used. With such apparatus the track contact 50 may, as shown in Fig. 2, be arranged intermediately of the multiple-finger contact device 51 or may even be provided by one of the intermediate contact fingers.
