Patent GB-643177-A (GB)
Title: Improved start-and-stop mechanism for gramophones and the like
IPC: G11B17/02
Filed: 1947-11-25
Abstract: 643,177. Switches held set and freed mechanically. MATTHEWS, S. R., and SMALL ELECTRIC MOTORS, Ltd. Nov. 25, 1947, No. 31207. [Class 38(v)] [Also in. Group XXXVIII] A start-stop mechanism for a gramophone in which movement of the pick-up actuates a switch controlling the turntable motor, comprises a switch operating arm 5 which is carried by and pivoted to a lever 8 pivoted at 10 to a support, translatory movement being possible between the arm 5 and lever 8, and detent means 6<SP>1</SP> being provided to hold arm 5 in the " on " position against the action of spring 13 so that rotation of arm 5 relative to lever 8 results in arm 5 being moved to the " off " position under the action of spring 13. During playing of the record, arm 20, which is fixed to the pick-up spindle, engages tongue 12 and rotates lever 8 and arm 5 about pivot 10. If the record has an eccentric runoff groove, the reverse movement of arm 20 engages tongue 7 on arm 5 which, since lever 8 is restrained by a frictional washer on pivot 10, causes pin 15 on lever 8 to be released from slot 6' on arm 5 so that insulated plate 4 of arm 5 separates the motor switch contacts 4<SP>1</SP> and stops rotation of the turntable. If no eccentric run-off groove is provided, the insulating plate 4 is arranged to engage a fixed pin 33 at some predetermined angle of rotation of the pick-up member to produce the same result. A slight outward movement of the pick-up arm beyond its normal position re-sets the mechanism due to the action of spring- controlled arm 24, the arm 5 being moved relative to lever 8 by the action of pin 29 on the wedge-shaped surface of plate 4.

Title: Improvements in diethers of polyoxyalkylene diols
IPC: E21D1/08
Filed: 1947-11-29
Abstract: Polyoxyethylene - oxy - 1,2 - propylene diols or mono-ethers thereof, containing (apart from the terminal diol or hydroxy and ether groups) 1/3 to 9 parts by weight of 1,2-propylene oxide for each part by weight of ethylene oxide and having an average molecular weight of at least 500 are converted to aliphatic diethers by reaction with a dialkyl sulphate or aliphatic halide in presence of an alkali metal hydroxide.  The diols used as starting materials may be prepared by the process of Specification 610,505 or 651,712, and the mono-ethers thereof may be prepared as described in Specification 584,367 or 616,256.  The products are suitable, alone or with other materials, e.g. lubricating oils or mono- or di-ethers of glycols, as lubricants (see Group III), or pressure transmitting fluids (see Group XXIX). Preferably 1 to 2 mols. of diethyl sulphate or 1 to 4 mols of alkyl halide are used for each hydroxyl group in the starting materials, and 2 mols of alkali metal hydroxide per mol. of diethyl sulphate or 1.25 mols. per mol. of alkyl halide.  Dibutyl ether or toluene may be the reaction medium using dialkyl sulphate, a temperature of up to 100 DEG  C. being used.  The product is washed and/or neutralized with carbon dioxide or phosphoric acids and stripped of water diluent and alkyl sulphate by heating to 185 DEG  C., if desired with reduced pressure.  Toluene is the preferred reaction medium when using an alkyl halide, temperatures of 100 - 140 DEG  C. being employed. Products prepared from monoethers may have a second ether group which is the same as or different from the initial one.  The viscosity of the products changes more slowly with temperature than that of the starting materials.  Reference is made to ether groups having up to 18 carbon atoms but the preferred ones have 2 to 8 carbon atoms. Examples describe the preparation and properties of the following ethers (1), (6), (7) and (14) butyl, ethyl; (2) methyl, ethyl; (3) ethyl, ethyl; (4) butyl, ethyl; (5) tetradecyl, ethyl; (8) butyl, butyl; (9) butyl - n - octyl; (10) butyl - n - dodecyl; (11) butyl, 2-ethylbutyl; (12) butyl, 2-ethylhexyl; (13) butyl allyl. They illustrate the use of starting materials with varying proportions of oxyethylene and oxy-1,2-propylene groups and of varying molecular weights.ALSO:Aliphatic diethers of polyoxyethylene-oxy-1,2-propylene diols (see Group IV (a)), are used alone or with other materials as lubricants.  They have low temperature coefficients of viscosity. They are miscible with hydrocarbon oils.  Some of the products are water-miscible and may be used as metal lubricants with non-aqueous viscosity-reducing diluents, e.g. the mono- and di-ethers of glycols or their polymers, e.g. the mono-butyl ether of tetraethylene glycol.
