Patent GB-834883-A (GB)
Title: Ethylene-imine-alkylene-oxide resins
IPC: C08G73/02
Filed: 1956-03-09
Abstract: Resins are prepared by reacting esters of the general formula <FORM:0834883/IV (a)/1> in which R1 is a monoto hexa-valent hydrocarbon radical with 1-10 carbon atoms, the chain of which may be interrupted by O, S, or tertiary N, R is a divalent radical containing 2-14 carbon atoms and n is a whole number from 1 to 6, with a compound containing more than one ethylene oxide group which may be obtained by reacting a polyhydric phenol or alcohol with epichlorhydrin or by epoxidizing unsaturated substances.  Examples of radicals which may be represented by R are <FORM:0834883/IV (a)/2> Some esters mentioned are as shown in the formulae <FORM:0834883/IV (a)/3> The reaction may be at room or raised temperature and may take place without a catalyst, and in presence or absence of solvents or diluents, examples of which are given.  The products may be soft and rubber-like or extremely hard.  Either or both of the components may be pre-polymerized with a catalyst specific for that purpose. Pre-polymerization should cease before insoluble or infusible products are produced.  In Examples 1-3 and 6, the ester used is bis-(b -ethylene-imino-butyric acid)-diglycol ester.  It is reacted with (1) a resorcinol epoxide resin to give a casting resin of low viscosity useful for intricate shapes; (2) with the same resin, the mixture being prepolymerized before hardening with dipropyl sulphate; (3) and (6) with a resin from 4,41-dihydroxydiphenylpropane-2 and epichlorhydrin.  In Example (4) bis-(b -ethylene-imino-propionic acid)-diglycol ester is reacted with a resorcinol epoxide resin. Example (5) is similar but uses b -ethyleneimino propionic acid methyl ester.  In Example (7) bis-(b -ethylene-imino-butyric acid) glycol ester is heated with an epoxide resin from 4,41-dihydroxy diphenyl dimethyl methane and epichlorhydrin to give a precondensed resin which is readily cured with phthalic anhydride.  Example (8) compares the hardening effect on the glycidyl ether of glycerol, of tri - (b  - ethylene - imino - butyric acid) glycerol ester; bis-(b -ethylene-iminobutyric acid)-glycol ester and pentaerythritetri - (b - ethylene - imino - butyric acid) (monocrotonic acid)-ester. Example (9) is similar but uses an epoxide from epichlorhydrin and butanediol-1,4.  Example (10) uses hexanetriol glycide ether, and Example (11) uses a resin from epichlorhydrin and 4,4-dihydroxydiphenyldimethyl methane. Specification 461,354 is referred to.

Patent GB-297311-A (GB)
Title: Electric furnace for heating strip metal by induction currents
IPC: F27D11/06
Filed: 1928-03-15
Abstract: 297,311. Hirsch Kupfer-und Messing- werke Akt.-Ges., and Tama, M. Sept. 17, 1927, [Convention date]. Induction furnaces.-To anneal strip metal it is wound in the form of a coil and placed in an ironless induction furnace so as to constitute a secondary. The primary coil I of flat copper strip or tube is mounted on an insulating cylinder 5 and bolted between flanges 23. The strip metal forming the secondary 17 is wound on a drum mounted on an axle 7 and resting on a layer 6 of refractory material forming the furnace bottom. A frequency of 50 or 60 cycles is used and the depth of the winding is not greater than the depth of penetration of the reduced currents. The furnace is sunk into the floor of the shop and is provided with a cover comprising a non- magnetic shell 14 containing a refractory filling. The shell may be of a chrome,-nickel alloy. The cover tilts about a pivot 10 and is fitted with a counterweight 11<a>, an eccentric water-seal 13, an inspection channel 16, and a non-return valve 15 allowing the escape of hot air. The drum carrying the metal strip comprises upper and lower discs or stars 18<a>, 19<a> having hubs 18, 19 connected by a sleeve 20 secured by bolts 21 to flanges 22, 23 on which is arranged a metal shell 24. The shell 24 is of material of greater resistance than the metal strip and is subdivided so as not to form a closed secondary. The metal strip may be bound to the drum to prevent sagging due to the strip expanding more than the drum. Fig. 2. shows a drum wherein the shell 32 is made in eight sections which are urged outwards by a weight 40. Vertical ribs 34 on the sections are connected by a links 36, 38, to the weight 40 and lugs 39. The weight 40 is provided with hooks 44 and is mounted on a sleeve 42 which is adapted to slide on the sleeve 28 connecting the hubs. The sleeves are coupled together by a removable pin 43 when the drum is being wound, and the drum is then lowered into the furnace by means of the hooks 44. The pin 43 is then removed to enable the drum to take up expansion during heating. Fig. 4 shows a plant having a turntable 62 adapted to support three drums. The furnace proper 45 is adapted to be raised and lowered by a rope 49. While heating and cooling respectively are taking place on two of the drums the third drum 57 is being wound or unwound by means of a toothed wheel 59 coupled to a suitable drive. The fourth drum is supported on a pivot 60. Instead of a turntable a reciprocating platform may be employed. Also provision for a greater number of drums may be made.

Patent GB-357191-A (GB)
Title: Improvements in arrangements for modulating radiation, particularly for use in picture-telegraphy, television, telephony by beams of light, and talking pictures
IPC: H04N5/66
Filed: 1930-03-12
Abstract: 357,191. Recording sound optically. MUELLER, C., 86, Sorrstrasse, Charlottenburg, Berlin. March 12, 1930, No. 8092. [Class 40 (ii).] In optical sound recording,light from a source 2, Fig. 1, is reflected from a membrane 4, and forms an image 5 in the plane of a diaphragm 6 so that the amount of light passing the diaphragm varies in accordance with the curvature of the membrane 4. The membrane 4 preferably consists of cellulose, or artificial resin, &c., provided with a reflecting coating and has its curvature varied by electromagnetic or electrostatic means or by sound waves falling directly upon it. The collimating lens 3 may be replaced by two half-lenses, Fig. 2, so that even should the membrane flex so as to cause the image to fall between the lens 3, Fig. 1, and the diaphragm 6 no light will pass beyond the diaphragm 10, Fig. 2. The diaphragm 6 may be replaced by a slit 38, Fig. 15, in a screen, which may be inclined to the line image 38 of the source 2, or the slit and image may assume different shapes. The sensitivity of the device is increased by using small sources of light such as an illuminated diffraction grating, when the diaphragm is also constituted by a similar grating. The lens 3 may be replaced by a concave mirror 32, Fig. 7, the light being reflected from the source 33 onto the modulating membrane 31 and back again to the screen 34. The lens 3 may be modified, e.g. by providing a reflector at its centre, so as to cause the light to undergo several reflections from the membrane, Fig. 29 (not shown), or this result may be obtained by the use of a concave mirror 61, which may be apertured, Fig. 8, or not apertured, Fig. 9 (not shown). The modulating action may be modified by movements of the mirror 61. Since the edges of the membrane 4 have the greatest effect in altering the width of the reflected beam, itscentre portion may be blacked out, e.g. by the condenser plates 11, 12, or the light reflected from this centre portion may be deflected laterally and used for control or observation of the source &c. The membrane may be reflecting on both surfaces and may modulate two rays, while it may also have a selective action for a particular wave-length. The device may be housed in a casing in which the gas pressure is variable to control the damping of the membrane.

Title: Ring and traveller device for textile spinning and twisting frames
IPC: D01H7/60
Filed: 1956-03-15
Abstract: 791,023. Ring and traveller spinning apparatus. LEMAIRE, P., and DERREUMAUX, P. March 15, 1956 [June 11, 1955; Nov. 28, 1955], No. 8193/56. Class 120(2) In a ring and traveller device for textile spinning frames, the traveller is provided with arms curved inward on a radius of curvature substantially the same as that of the interior surface of the ring upon which it is mounted and which is provided with an annular rib. As shown, the traveller 2 has arms 2a, 2b which co-operate with the inside wall 1d, 1e of the ring 1 when the traveller is thrown out by centrifugal force and with the walls 1b, 1c of the flange rib 1a due to the tension in the thread 3 before the speed is sufficient for centrifugal force to overcome the force due to the tension. In a second modification (not shown), the flanged rib 1a has a substantially triangular section and the grooves and traveller are so shaped that the arms 2a, 2b are thrown by centrifugal force against the bottom as well as the sides of the grooves. Thus a larger contact area is obtained and pressure per unit area reduced, permitting higher spindle speeds. In both modifications a slit 5 is provided in the ring 1 to facilitate threading the traveller 2.
