Abstract: 1,186,815. Feeding webs. HERMANN BERSTORFF MASCHINENBAU G.m.b.H. 29 July, 1968 [2 Aug., 1967], No. 36174/68. Heading B8R. Apparatus for winding a web 1 on to cores 11 to form rolls comprises a continuously rotating drum 3 over which the web is fed, and levers 8 coaxial with the drum carrying a spool-receiving forked-bracket 10 and a knife structure 9 for transverse cutting of the web after completion of a roll, the levers 8 being first moved from a cutting and winding-initiating position II to position III where the partly wound roll is deposited on arms 16 for completion of the winding and subsequent delivery of the wound roll, then moved back to position I to receive an adhesive-coated core from a magazine and finally returned to position II for severance of the web and initiating winding of a new roll. The levers 8 are moved anticlockwise by coupling them by an electromagnetic clutch 15, Fig. 2 (not shown), to the drum 3 and are rotated in the reverse direction by a separate hydraulic motor (7). At position II, a knife forming part of a structure 9 is moved transversely of the web by a serewed shaft and is lifted during its return movement. During the movement from position I to position II, the bracket 10 holds the core 11 spaced from the web, but when cutting is completed, one prong of the bracket 10 is moved radially inwards by an hydraulic cylinder 14 so that the adhesive-coated core engages the leading end of a new length of web and winding of a new roll is initiated. At position III, a catch 16a on the arms 16 is opened to allow the initiated roll to be deposited in the arms 16, and the roll is pressed against the drum 3 by the action of an hydraulic cylinder 19 connected to a slidable carriage 18 to which the arms 16 are pivoted. When the roll reaches a predetermined diameter, a control signal causes movement of the levers 8 as described above. At the same time, the hydraulic cylinder 19 moves the carriage 18 to the left, an hydraulic motor 17, Fig. 5 (not shown), swings the arms 16 anticlockwise, and the catch 16a is released so that the roll is discharged. As described above, the knife makes an oblique cut across the web, but a cut perpendicular to the web edges may be obtained by moving the levers 8 anticlockwise as the knife makes its stroke.

Abstract: 1,211,396. Television. SONY CORP. 30 July, 1968 [1 Aug., 1967], No. 36362/68. Heading H4F. In an automatic dark current control system for a pick-up tube a light transmission inhibiting region is provided on the target of the tube and the video signal level produced when this region is scanned is employed to control the target voltage to hold this level constant. Thus, as shown in Fig. 3, a mask 8 is disposed on the target 5 and the video signal level E B  (Fig. 4) occurring in a dark current period T D  following the horizontal fly-back period T B  and due to the presence of the mask is detected by a circuit 10 (Fig. 2), comprising e.g. a sampling circuit supplied with horizontal synchronizing pulses derived from the deflection circuit 12, and compared with a reference voltage E in a comparator 13 the output of which is applied to a target voltage control circuit 14 which controls the target voltage by feed-back to maintain level E B  substantially constant. The invention compensates for dark current changes due to temperature variations and is of particular advantage in maintaining white balance in colour television cameras employing a plurality of pick-up tubes. The mask 8 may be positioned along a horizontal edge of the target instead of, a vertical edge.

Title: Process for the production of 2-chloroacrolein and derivatives thereof
Filed: 1955-12-21
Abstract: 2-Chloroacrolein is manufactured by dehydrochlorinating 2:3-dichloropropionaldehyde with hot water in the absence of alkali but in the presence of a primary or secondary monohydric alcohol of not more than 10 carbon atoms per molecule, preferably in an amount at least equal to the weight of 2:3-dichloropropionaldehyde, e.g. in a proportion of 4-8 mols. of alcohol per mol. of 2:3-dichloropropionaldehyde.  A preferred procedure consists in introducing 2:3-dichloropropionaldehyde and the alcohol, separately or in admixture, into water (with or without a minor proportion of the alcohol) maintained at refluxing temperature, recovering a condensate containing water, alcohol and 2-chloroacrolein, and dehydrating it.  The mixture of alcohol and 2-chloroacrolein may then be distilled to recover the latter, or (when the alcohol is ethanol) may be reacted with additional ethanol to form 2-chloro-1:1:3-trietoxypropane, which may be dehydrochlorinated (e.g. by the action of caustic alkali in the presence of a dehydrating catalyst) to form 1:1:3-triethoxy-2-propene.  Examples illustrate the various features of the invention using ethanol as the alcohol.  In the example of the preparation of 2-chloro-1:1:3-triethoxypropane, 2 - chloro - 3 - ethoxypropionaldehyde and 2-chloroacrolein diethyl acetal are found as byproducts.  Other alcohols specified are methanol, n- and iso-propanols, primary and secondary butanols and pentanols, 2-ethylbutanol, 2-ethylhexanol and cyclohexanol.  Starting material.  2:3-Dichloropropionaldehyde is prepared by passing chlorine into a solution of acrolein in carbon tetrachloride at 0 DEG C.

Abstract: 635,267. Electrolytic production of metals. HUSQVARNA VAPENFABRIKS AKTIEBOLAG. Dec. 13, 1946, No. 36866. Convention date, Dec. 18, 1945. [Class 41] Metals or alloys (including carbides) in the form of powder for powder metallurgical processes are produced by electrolysis in a fused salt or salts of an alkali or alkaline earth metals, e.g. chlorides or fluorides of sodium, potassium, lithium and calcium, employing an anode containing a reducible compound of a heavy metal and a reducing agent therefor and carrying out the electrolysis at a temperature at which reduction of the reducible compound can take place but below the melting point of the metal which is deposited at the cathode as powder. The reducible metal compound such as finely-divided iron ore or nickel oxide or chromium oxides, and the reducing agent such as finely-divided carbon with a binder such as mineral coal tar, are shaped and heat-treated to form an anode. Alternatively the anode may comprise a mixture of finely-divided ore and carbon with or without a binder packed into metal tubes and advanced down the tube into the bath and being dried and sintered during the advance. Instead of the mixture of metal compounds two or more anodes containing different alloying components may be used and optionally supplied with different voltages and/or current densities. Carburization of the metals deposited at the cathode may be effected by any carbon containing gases liberated during the reduction at the anode which must be sufficiently near to the cathode. The anode may contain material, e.g. turnings for increasing the strength and/or porosity of the anode. The bath may contain one or more molten halides, cyanides, borides or phosphates of the alkali or alkaline earth metals. Iron and steel are produced, using carbon as a reducing agent, at between 600‹ and 900‹ C. Aluminium may be used as the reducing agent for chromium and titanium oxides, the aluminium oxide formed in the bath being separated therefrom by circulating and filtering the electrolyte. Hard metals may be produced by employing cobalt oxide, tungstic acid or titanic oxide with a sufficient amount of carbon for reduction. Tantalum may wholly or partly replace tungsten and nickel may replace cobalt.
