Title: Phonograph
IPC: G11B3/40
Filed: 1965-04-13
Abstract: 1,080,102. Record players. ARGUS Inc. April 13, 1965 [April 29, 1964; Aug. 25, 1964], No. 15644/65. Heading G5R. In a record player the loud-speaker, amplifier and pick-up arm are mounted for rotation relative to a stationary record. Housing 11, enclosing speaker 19, drive motor 31, battery power supply, record player amplifier and possibly a radio tuner unit, is mounted for rotation on a pedestal 16. The pedestal includes a circular base portion 21, which fits the centre hole 22 in the record 23, and a vertical grooved circumferential surface 28 which is engaged by the drive wheel 33 of motor 13 to drive the housing about the pedestal and record. An alternative smaller diameter record locating member used for locating the pedestal on records with a smaller centre hole is releasably secured in a compartment at the centre of the bottom surface of the base portion 21. The housing is provided with a jack 41 which receives a keyed plug 42 to which a tone arm support member 43 is secured by a resilient member formed of a piece of tubing. The tone arm 51 is pivotally attached to its support member 43. Insertion of the plug opens the circuit between the tuner unit (if present) and the amplifier and connects the record pick-up to the amplifier. The position of the keyed plug in the jack is such that in the absence of a record the tone arm is disposed at an angle below the generally horizontal position necessary for operation, thus in the operational position the resilient tube connector exerts a torsional force to increase the downward force exerted on the needle by the arm 51. The tone arm support member and the tone arm may be adjustable in length to accommodate different sizes of records. The drive is adjusted to the various record speeds by switching different values of resistance into the motor circuit. Means are also provided, Fig. 7 (not shown), for automatic repeat playing of a record. In a second embodiment using a clockwork motor the motor drive wheel engages the surface of the record, the position of the drive wheel relative to the centre of the record being adjustable to accommodate different record speeds.

Title: Process of producing tertiary nitriles
Filed: 1926-06-22
Abstract: 253,950. I.G. Farbenindustrie Akt.- Ges., (Assignees of Farbwerke vorm. Meister. Lucius, & Br³ning). June 22, 1925, [Convention date]. Samples furnished. Nitriles; acid amides. - Tertiary nitriles are produced by acting on a secondary aliphatic nitrile with an alkali metal, in the presence orabsence of a solvent, to form an alkali compound which is then treated with an alkylating or aralkylating agent. By subsequent saponification the acid amide is obtained. In examples (1) diethylallylacetonitrile is produced by the action of potassium on diethylacetonitrile, using ether,. benzene, or xylene as solvent, and subsequent heating with allyl bromide; saponification gives diethylallyiacetamide; (2) diethylbenzylacetonitrile is produced in a similar manner using benzyl bromide instead of allyl bromide, and this on saponification gives the amide. Specification 210,809 is referred to.

Title: Improvements in or relating to thermal cut-out switches
IPC: H01H61/02
Filed: 1930-05-22
Abstract: 356,110. Thermostats. AKTIEBOLAGET BIRKA REGULATOR, 48, Surbrunnsgatan, Stockholm. May 22, 1930, No. 15841. Convention date, May 25, 1929. [Class 64 (ii).] A thermal cutout switch 1, adapted to open by the expansion of a solid member 5 in a sealed glass vessel 1, upon overheating or overload, is held open by means of a heating winding 6 connected across its contacts. The member 5 may, as shown, take the form of a frame attached to two rod contacts 4. To reclose the switch the circuit must be temporarily opened elsewhere. Fig. 3 shows a form in which the switch is caused to open by means of a heating winding 7 which is energized when an auxiliary switch 9 in thermal communication with an electric heater 2 is closed. Opening of the contacts 4 puts the winding 6 into circuit and the contacts 4 therefore remain open even when the switch 9 opens. Fig. 6 shows a modification in which a second auxiliary switch 11, adapted to close at a lower temperature than the switch 9, is used. When the temperature falls owing to the opening of the contacts 4, the switch 9 will first open but current will still flow through the switch 11 and winding 6. At a lower temperature, the switch 11 opens, breaking this circuit so that the switch 1 then automatically recloses. Several switches 11 in parallel may be used situated at different places to ensure that the temperature is sufficiently low everywhere before the switch 1 can close.
