Title: Improvements in or relating to talking machines with an automatic disc changing device
IPC: G11B17/02
Filed: 1951-10-23
Abstract: 689,766. Automatic gramophones. PAILLARD SOC. ANON. Oct. 23, 1951 .[July 7, 1951], No. 24688/51. Class 40 (ii). In an automatic gramophone, means for producing a pause between record playings comprises a device for stopping a cycling cam-disc, and a w i r e which becomes wound on a shaft and acts as a control member for restarting the camdisc when a predetermined length of wire has been wound on the shaft. In one embodiment, Fig. 1, a cam-disc 1 is driven, during an automatic cycle, by a continuously rotating gearwheel 5, which idles in a recess 3a in the cam-disc while a record is being played. When an automatic cycle commences, the cam-disc 1 rotates until arrested by the contact of a pin 22 of a lever 20 which is biased against a stop 24 'by a spring 23. At this moment the gearwheel 5 idles in recess 3b in the cam-disc, and a pin 8 on the end of a bellcrank 9 is moved into a hollow in a central cam 7 under the influence of a spring 11, whereby the hub 15 of a star wheel 14 is brought into contact with a friction pad 17. At each revolution of the gearwheel 5, a pin 18 thereon moves the star wheel 14 an angular amount, corresponding to one of its teeth, to slowly wind a wire 31 on to its shaft 12, and serves to pull a bellcrank 25 against the tension of a weak spring 32 until a pin 28 thereon comes into contact with an adjustable cam 29. When this happens, continued tension in the wire 31 causes the lever 20 to be pulled out of the path of pin 4b and into contact with a ramp 19b so that the cam-disc is moved until the gearwheel 5 is re-engaged and the automatic cycle completed, In an alternative embodiment, Fig. 4, a threearmed lever 34 replaces the levers 20, 25, the time delay then being effected by the amount of wire required to draw the end 41 of arm 39 clear of the pin 4b, and the restarting of the cam-disc effected by the arm 38 coming into contact with the ramp 19b. Adjustment of the time delay is made by connecting the end of the wire to one or other of the points 35a, b, c or d.

Title: Chloroalkane manufacture
IPC: C07C17/00
Filed: 1956-08-17
Abstract: Ethyl chloride is produced, with or without other chloroalkanes, by subjecting a mixed gaseous feed of an alkane, ethylene and hydrogen chloride to liquid phase aluminium chloride catalysed ethylene hydrochlorination conditions in a hydrochlorination zone to convert the ethylene to ethyl chloride but leaving the alkane unreacted, passing some or all of the unreacted alkane from said hydrochlorinating zone, with additional alkane if desired, into a chlorinating zone, introducing chlorine into the chlorinating zone, maintained under conditions to effect suitable chlorination of a part of the alkane to produce additional chloroalkanes and hydrogen chloride, and passing at least a part of the unreacted alkane (and, if desired, at least a part of the chloroalkanes) to the hydrochlorination zone, together with at least a part of the hydrogen chloride to provide that required to react with the ethylene. Advantageously the chlorination is carried out at a temperature above about 660 DEG  F. in a fluidized bed, and the reaction gases therefrom may be subjected to a pressure drop exceeding about 50 inches of water in the presence of anhydrous liquid.  If the alkane employed is ethylene, the product of the chlorination reaction will, under suitable conditions, be essentially ethyl chloride.  Any polychlorinated by-products may be removed from the chlorination zone product prior to recycling of hydrogen chloride, unreacted ethane, ethyl chloride and water to the hydrochlorination zone. Any finely divided carbon carried over with the reaction products may be removed by passing the gases through a solids separator (e.g. a fluid scrubber), and this may employ a drying liquid (e.g. aluminium chloride solution or sulphuric acid) to remove water simultaneously. The ethyl chloride is preferably recovered following the hydrochlorinating step, but in some cases can also be separated directly from the chlorination product provided water contaminant is removed as a separate phase in the reflux drum of the fractionating tower.  Examples illustrate the various features of the invention as applied to the production, under various conditions, of ethyl chloride alone, of ethyl chloride plus chloromethanes, and of ethyl chloride plus dichlorethanes.
