Title: Electric sewing machine outfit
IPC: D05B69/18
Filed: 1928-01-21
Abstract: 291,707. Fairweather, W., (Singer Manufacturing Co.). Jan. 21, 1928. Driving.-The table of a drop-head electrically-driven, sewing-machine has one of the legs channelled to house the vertical control rod for the motor and bored at the bottom to receive a detachable pedal. The table 2 has the usual well to receive the machine 8 and motor 10 when not in use, and one leg 4<1> has a channel in which is housed the rod 29 pressed by a spring 46 on the flat part 28 of a cam 25 rotatable in a bearing 24 in the foot of the leg. When the pedal 32 is depressed against its spring 41, a tooth 31 on a sleeve 36 rigid with the pedal shaft 35, engages a tooth 30 on the cam and lifts the rod 29. An arm 43 rigid with the rod and projecting through a slot 44 in the leg then lifts an arm 48, through an adjustable screw 47 to rotate a shaft 20 and cause the inclined edge of another arm 19 to rock the. bell crank lever 16 about the pivot 17 and pull the rod 15 to cause the bow spring 14 to put pressure on the staoks of carbon discs 13 of the controlling rheostat and so govern the speed of the motor. In the case of a portable machine, Fig. 9, lowered into the well of the table, the screw 66 of the rod 62 operates on a pivoted arm 70 which engages an arm 72 on the shaft 73 which is put into, or out of, engagement with the control shaft 57 of the motor at will, through an opening in the side of the machine box.
Patent GB-846234-A (GB)
Title: Improvements in or relating to the production of monovinylacetylene
IPC: C07C2/38
Filed: 1959-01-20
Abstract: In the preparation of monovinylacetylene by dimerisation of acetylene in the presence of an aqueous cuprous chloride catalyst containing dispersed therein 1.5-20% by weight of a monoalkyl ether of diethylene glycol as in U.S.A.  Specification 2,914,587, the ether is recovered from the resultant ethereal layer containing tarry acetylene polymers by mixing with 2-15% aqueous hydrochloric acid and a liquid solvent hydrocarbon containing more than 50% by weight of aromatics, separating into a lighter layer comprising tar and hydrocarbon and a heavier layer comprising the ether and acid which latter is recycled to the reaction.  The ether usually contains about 3-30% of tar and each part by weight is mixed with 3-5 parts of acid and 1/3 -3 parts of hydrocarbon which may boil in the range 85-155 DEG C., and may contain benzene, toluene or xylenes, the mixing and separating steps being effected at 15-75 DEG C.  The acid used is generally obtained from the scrubbing operation with dilute hydrochloric acid applied to the acetylene-monovinylacetylene product mixture which operation also removes any ether carried over with the gases.  In one embodiment this acid is partly used in the mixing step and a further part is mixed with the hydrocarbon-tar effluent to remove further amounts of ether.  The aqueous-ether lower layers obtained from these two steps may be combined and partially distilled to remove some acid before recycling the bottoms containing just sufficient acid to the reaction vessel.  In another embodiment the major portion of the acid from the scrubbing operation is used in the second of the above mixing steps and the aqueous-ether layer so obtained used in the first mixing step, the lower layer from which is recycled.  The excess of the acid from the scrubbing operation over that required for recycle is either discarded or is firstly mixed with the incoming solvent hydrocarbon before being separated and discarded.

Title: Improvements in or relating to the production of alpha-chloro, beta-hydroxynitriles
Filed: 1943-02-15
Abstract: a -Chloro-b -hydroxy nitriles are prepared by reacting an aqueous solution of an a -b -unsaturated nitrile containing not more than four carbon atoms in the molecule with chlorine or hypochlorous acid at a temperature between 0 DEG  C. and 30 DEG  C., preferably 10-20 DEG  C., whilst the concentration of the unsaturated nitrile in the solution is maintained at or below the solubility value at the reaction temperature, whereby the whole of the nitrile remains in solution throughout the reaction period.  A mixture of water and a water-soluble alcohol or ketone, e.g. acetone, may also be used as the solvent, the mixture containing preferably at least 50 per cent water.  The hydrochloric acid set free in the reaction may be neutralized, if desired, by adding neutralizing agents such as alkali or alkaline earth metal hydroxides, carbonates, or salts of weak acids; alternatively an excess of calcium carbonate may be added at or near the commencement of the reaction.  The aqueous solution should not be alkaline.  Additional a -b -unsaturated nitrile may be added during the reaction, continuously or intermittently, so long as the solubility limit is not exceeded.  The a -chloro-b -hydroxy nitrile is extracted by a solvent such as ether, ethyl acetate or a water-immiscible alcohol.  U.S.A. Specification 2,231,360 is referred to.  In examples: (1) acrylonitrile in aqueous solution is treated with chlorine at 18 DEG  C., and the resultant a -chloro-b -hydroxy propio nitrile extracted with ether; (2) crotonitrile is treated likewise to yield a -chloro-b -hydroxy butyro nitrile.

Abstract: 782,850. Grinding and polishing glass and other surfaces. GLACERIES DE LA SAMBRE SOC. ANON. Jan. 27,1955 [Jan. 27, 1954], No. 2548/55. Addition to 755,832. Class 60. [Also in Groups XXVI and XXXVII] Apparatus for grinding or polishing a moving sheet 5 of glass or similar material comprises rotary tools 1 mounted on beams 3 which are supported on carriages for reciprocation across the sheet 5, a mechansim for reciprocating the beams and a second mechanism by means of which the velocity of the beams is maintained constant during a portion of the reciprocation, one of the mechanisms being a crank and connecting rod. The reciprocation may be produced by a connecting rod and crank driven by an electric motor 10 having a variable resistor 32 in its field circuit. The slider 31 of the resistor 32 is actuated through gearing 27 ... 30 by a cam 23 mounted on the crank shaft so that the speed of the motor is varied to produce a reciprocating movement of substantially uniform velocity. In an alternative arrangement, Fig. 5, a first reciprocating movement is imparted to a carriage 37 by a crank and connecting rod 35, 36 while a second reciprocating movement is imparted to a carriage 38 by a second crank and connecting rod 39, 40 so that the carriage 38 which is connected to the toolsupporting beam 3, reciprocates with substantially uniform velocity. The crank 39 may be actuated by a motor with a reduction gear or, as shown, through gearing 43 .... 48 from one of the tool shafts 42. The connecting rods may be made in two parts (see Group XXVI) to permit staggering of the beams in relation to one another to secure a uniform grinding or polishing action over the width of the glass. The upper and lower beams of each pair may also be staggered in relation to each other to reduce variations in the thickness of the glass.
