Patent GB-866365-A (GB)
Title: Trimethylolethane
IPC: C07C31/18
Filed: 1958-03-12
Abstract: Trimethylolethane is recovered from an aqueous solution also containing sodium formate by extracting the solution with an amyl alcohol or a mixture of amyl alcohols to produce an amyl alcohol solution of trimethylolethane and recovering trimethylolethane from this solution.  Preferably the trimethylolethane is recovered from the amyl alcohol solution by extracting with water to produce an aqueous solution of trimethylolethane and crystallising the trimethylolethane from this solution after concentration.  Before carrying out the aqueous extraction it is preferred to wash the amyl alcohol solution with a little water to remove dissolved sodium formate.  It is preferred to carry out both extractions countercurrent with the aqueous phase as the continuous phase.  The process may be used for the recovery of trimethylolethane from the solution produced by the reaction of propionaldehyde, formaldehyde and sodium hydroxide.  The preferred temperature for the extraction with amyl alcohol is 70-80 DEG C. and also for the subsequent extraction with water. Specifications 790,759 and 790,760 are referred to.

Title: Improvements in butt welding devices for metal strip
IPC: B23K11/087
Filed: 1938-03-16
Abstract: 490,916. Welding metal strips. WILLIAMS, W. P. (American Rolling Mill Co.) March 16, 1938, No. 8070. [Class 83 (iv)] In a welding device comprising a pair of relatively movable heads carrying clamps, particularly for welding strips from hot rolling mills end to end so as to increase the size of the coil available for further reduction by cold rolling, shafts mounted in one of the heads carry gauge arms which may, by rotation of the shafts, be brought between the ends of the strips so as to space them endwise in parallel relationship prior to welding, means being provided for moving the arms laterally to avoid contact with the movable head during welding. The head 9, which may be moved by fluid pressure, and the fixed head 10, respectively carry electrodes 5, 6 secured to the terminals of a transformer 7, and are provided with clamps 11, 13 operated by fluid pressure for holding the strips 1, 2. A pair of shafts 16 carrying end gauge arms 4 are journalled in sliding insulated bearings 9<1> in the head 9 and are threaded at 10<1> into the head 10 so that on rotation of the shafts by rack and pinion mechanism 18, 17 from a fluid pressure cylinder, the shafts may also move axially so that in the upraised position they are moved clear of the movable head. The strips, which may be of different width are also positioned laterally so that their centres are in alignment. For this purpose each welding head carries a pair of telescopic shafts 23, 24 provided with brackets 22 and abutments such as rollers 21 for engaging the edges of the strips. The shafts are connected respectively by links 23<1>, 29 and 241, 30 to opposite sides of a lever 28 which is pivoted at 31 and operated by a fluid pressure cylinder 25, so that the shafts move equally in opposite directions.

Title: Improvements in recording images by means of phosphors
IPC: G03C5/17
Filed: 1947-03-25
Abstract: 650,457. Luminescent recording processes. KODAK, Ltd. March 25, 1947, No. 8159. Convention date, March 26, 1946. Drawings to Specification. [Classes 98 (i) and 98 (ii)] [Also in Group XL (a)] A method of delayed-action recording of a short wavelength image comprises projecting the image on to a layer of a phosphor which stores the exciting radiation and releases at least a part of it, when stimulated with longer wavelength radiation such as red or infra-red light, as light of intermediate wavelength, placing the excited phosphor layer in contact with, or if a projection system is interposed, in a plane conjugate to that of the recording layer and stimulating the excited phosphor to form an image on the recording layer. This layer may either be a photographic layer and a permanent image formed by the usual processing steps or merely a layer on which the image can be observed and recorded manually as by tracing. Numerous examples of suitable phosphors are given in the Specification and are included in the list given in Specification 650,455. When making copies of an original, the phosphor is excited image-wise by passing light from an ultra-violet lamp through the orignal or causing such light to pass through the phosphor first, when it then is excited by the light reflected from the more opaque parts of the original. The excited phosphor is then stimulated by uniform illumination with infrared light so as to print on to a light-sensitive sheet contacting the phosphor by means of the light emitted by the latter. If several prints are required from a single excitation of the phosphor the intensity of the stimulating infrared light is progressively increased to maintain the exposure time constant. To increase the sensitivity of the phosphor to the stimulating infra-red, it may be initially either strongly excited with ultra-violet and partially exhausted with infra-red, or partially excited with ultra-violet. In an application to recording galvanometer deflections, ultra-violet light is reflected from the galvanometer mirror and projected on to a continuously moving phosphor band. The faintly luminescent trace may be examined and either obliterated by flooding with red or infra-red light or a permanent record made on stimulating the phosphor with infra-red. Specifications 650,458 and 650,459, [both in Group XL (a)], also are referred to.

Abstract: 374,945. Multiplex telegraphy; thermionic valve distributers. STANDARD TELEPHONES & CABLES, Ltd., NASH, G. H., DUNHAM, C. R., and GROVE, S. H., Columbia House, Aldwych, London. March 19, ' 1931, No. 8447. [Classes 40 (iii) and 40 (v).] In a distributer for telegraphy or the like, the equivalent of a rotating arm is constituted by a beam of light which is rotated over a number of photo-electric cells. In a modification, beams of light from a series of sources illuminated in accordance with the signal elements to be transmitted are sequentially reflected on to a fixed photo-electric cell by the rotation of a mirror member. A narrow lightbeam B from a source L is rotated over photoelectric cells P1, P2, .. , and in accordance with the operated tongues of relays T1, T2 .. set up by a tape transmitter T, impulses pass from the corresponding members P1, P2 .. through an amplifier A to the line M. At the receiving end, Fig. 2, a beam B is similarly rotated over cells P1, P2, .. by which the valves V1, V2, .. are rendered operative in succession. A signal element from the line M passes to a modulator N associated with an oscillator O and through the valve VI, V2, .. operating at the instant to operate an associated trigger device F1, F2, .. and the corresponding printer magnet p1, p2, .. The coupling between the valves V1, V2 .. and the trigger devices F1, F2, .. is such that the latter are not operated by the successive operation of the valves unless the modulated signal is superposed. In a modified transmitting distributer, Fig. 3, the light sources S1, S2, S3 .. are illuminated in accordance with the signal impulses to be transmitted, and a rotatable mirror member M reflects to a fixed photo-electric cell PC1 lightbeams from the sources S1, S2 .. which are illuminated. At the receiving end, Fig. 4, a fixed source N is illuminated intermittently by the signal impulses and a rotating mirror M1 reflects the beams on to the corresponding cells P1, P2, P3, .. by which the associated trigger devices F1, F2, F3, .. are operated to control the printer p. In the schematic representation, Fig. 5, the light-sources S1, S2, .. are arranged in the plane of rotation of an inclined mirror M by which a light-beam is reflected from the selectively illuminated sources S1, S2 .. to a fixed photo-electric cell P mounted on the axis of rotation. For a receiving distributer, S1, S2 .. are photo-electric cells and P becomes the fixed light-source which is illuminated by the signals received. The mirror element may be carried on a vibrating reed, with the cells or light sources arranged in an arc. Specification 344,444 is referred to.
