Title: Improvements in a method and means of washing air, gases and vapours
IPC: B01D47/02
Filed: 1958-02-11
Abstract: 866,770. Washing gases. HEAT & AIR SYSTEMS Ltd., and WALKER, R. J. March 18, 1959 [Feb. 11, 1958], No. 4499/58. Class 55 (2). In apparatus for washing air, gases and vapours, the gas or vapour to be washed is drawn downwardly on to the surface of a body of liquid in a container 1, and a mixture of gas or vapour and liquid passes upwardly into a chamber 2 and is given a spinning motion by vanes 11, the gas or vapour then passes upwardly through plates 14 (which serve to remove entrained washing liquid) to an outlet 13, while the washing liquid and impurities washed from the gas or vapour are flung against and flow down the walls of the frustoconical portion 3 of the chamber 2 into the container 1. The vanes 11 are secured to a baffle plate 7, which is adjustably mounted on vertical rods 5 fixed to the lower end of the portion 3 of the chamber 2. The vanes may be rotated by mechanical or electrical means.
Patent GB-579867-A (GB)
Title: Improvements in production of biguanides
IPC: C07C279/26
Filed: 1944-03-10
Abstract: Biguanide and alkyl substituted biguanides are prepared by subjecting the corresponding copper biguanide sulphate in the presence of an aliphatic monohydric alcohol of not more than 4 carbon atoms to the action of an alkali metal sulphide.  Insoluble materials are removed and the biguanide recovered from the alcohol solution.  The alcohol is used in sufficient amount to dissolve all the biguanide.  In the examples, sodium sulphide is added to a mixture of copper biguanide sulphate and methyl and ethyl alcohol respectively, the reaction mixture being stirred and gently heated.  The product is filtered, the filtrate evaporated under vacuum and the biguanide precipitated by adding ethyl ether. Other biguanides which may be prepared in a similar way are stated to be ethyl, n-propyl, n-amyl, n-octyl, n-dodecyl, n-tetradecyl, n-octadecyl, diethyl, d-n-butyl, d-n-hexyl, di-2-ethylhexyl, di-n-tetradecyl, unsymmetrical dimethyl, unsymmetrical d-n-dodecyl and unsymmetrical d-n-octadecyl biguanide. Alcohol solutions of the biguanides may be used in the preparation of guanamines.  Thus stearoguanamine is produced by adding an ester of stearic acid to a methyl alcohol solution of biguanide.  The alcohol solution may also be used in the preparation of biguanide salts.  The Specification as open to inspection under Sect. 91 refers to the preparation of b -hydroxyethyl biguanide.  This subject-matter does not appear in the Specification as accepted.

Abstract: 585,529. Automatic circuit-breakers; thermal switches. WILMOT-BREEDEN, Ltd., and LEWIS, F. V. Feb. 26, 1945, No. 4776. [Class 38 (v)] A switch for controlling vehicle direction indicators a comprises a manually operable switch member c adapted to energize either indicator a and simultaneously to energize a holding winding e, this winding e being deenergized after a predetermined time interval by a thermal switch. The thermal switch is in series with the winding e and comprises heating coils k and bimetal strips g one or other of which is arranged on heating to move a lever h past the dead centre position of a toggle spring i. The circuit is then interrupted during the instant that the lever h is clear of both strips g.

Abstract: 1532841 Shearing HEINRICH GEORG MASCHINENFABRIK 9 Feb 1976 [17 Feb 1975] 5027/76 Heading B3W Programme controlled apparatus for cutting transformer core plates which are intended to be layered one upon the other within a transformer core assembly comprises strip supply means 2, reversible first feed means 5, a shear 4 adjustable about a vertical axis for shearing at different inclinations to the feed direction, second feed means 8 and a fixed shear 6. To cut trapezium-shaped side limb plates first, the shear 4 is disposed for shearing strokes alternately in the two positions shown, the resulting plates being removed by a run-out table 8<SP>1</SP> to a deflecting device 9 for stacking the plates with accurate overlapping. To change to intermediate limb plates, the feed means 5 is reversed to retract the strip by a distance x, Fig. 4(b) while the shear is pivoted. The shear then chamfers the leading corner 16 which is removed by a conveyer 11 to a scrap pit. After feeding the strip aplate length plus length x the sheer is pivoted and actuated. The plate is advanced and the strip retracted by the second and first feed means respectively, each by the length x, and the shear 4 is actuated to shear tips 16 and 17. On the last cut before a change back to shearing trapezium plates the plate is advanced by the length x and the strip is retracted by a distance y greater than x, Fig. 5(b) and a gag is operated to allow the shear only to remove the tip 17. The first trapezium shaped plate is sheared after feeding the strip a plate length plus the length y. To chamfer the leading tip (20) of trapezium plates, Fig. 6 (not shown) the fixed shear 6 is operated. Magnetically operated proximity sensors monitor the position of the strip for the programme control.

In a print copying machine, comprising a portable transmitting head 10 wherein light from the lamp 16 focused to a point by the lens 20 is caused by the oscillating mirror 18 to scan the height of the word to be reproduced, the reflections received by the photo-cell 30 along the lucite rod 28 control the input to the high-voltage reproducing probe 36 under which is conveyed electro-sensitive recording paper 42 and which is caused by the bar 34 and electromagnet 40 to oscillate at the same frequency as the mirror 18. As shown the mirror 18 and bar 34 are caused to oscillate by electromagnets 26 and 40 respectively supplied from a common transformer 52, a phase shift circuit 54 compensating for delays due to the length of the connecting lines. The probe 36 is supplied from highfrequency oscillator 58 through switch 60 and amplifier 62. The switch 60 is opened by the output from the photo-cell 30 amplified by amplifiers 32 and 64. In operation the head 10 is held in the hand and is passed along the print to be reproduced, the width of scan of the light beam being preset by the variable resistor 56. When no print is directly beneath the beam of light, reflections from the surface of the paper activate the photo-cell thus opening the switch 60 and switching off the supply to the probe 36.
