Title: Indication of changes in ambient conditions
IPC: G01K11/12
Filed: 1971-04-19
Abstract: 1353776 Polorizing apparatus S B ELLIOTT 19 April 1971 [12 March 1970] 23640/71 Heading G2J [Also in Division G1] A hygrometer comprises light transmitting layers 1, 4, Fig. 1, polarized at right angles to each other to produce a dark field, and a chemical crystal layer 3 deposited on a translucent substrate 2 which layer 3 is birefringent (double refracts light) at a first relative humidity but is non-birefringent at a second humidity. The layer 3 is formed of crystals containing unstable hydrates or alkali metals, many examples of which are given, and may split an incoming light beam into two rays vibrating at right angles to one another with a different velocity to give a phase difference therebetween, the beam then being generally referred to as elliptically polarized. The two components are resolved by the layer 4 into one plane polarized beam again but a phase difference has been introduced between its two parts. White light passing through will emerge from 4 either as brilliant colours or brilliant white, depending on the crystal size, but in either case the dark field now glows brilliantly. In a variation of Fig. 1 the layers 2 and 3 are in a roll form which may unroll close to a heated moving stylus in a recording instrument. The heated stylus forms a narrow line of non-birefringent crystals and traces a curve. In Fig.2 (not shown) the layers 1, 4 are formed by folding a single sheet at 45 degrees to its polarizing axis and the layer 3 may if required be deposited on 1 and 4 instead of upon 2. In Fig.3 (not shown) the layer 1 is perforated to allow air to stream therethrough and its humidity to be checked by viewing the colour of layer 4. In Fig.4 (not shown) one of the outer layers reflects light back to the first linear polarizing layer which then acts as an analyzer. In a variation the first layer may circularly polarize so that when the layer 3 is non-birefringent no light will be reflected through. The hygrometers thus described may be buried in materials to be tested for moisture content e.g. grain and allowed to remain there to equilibrate with the grain, or they may be sealed into a container with the apparatus to be checked. The layer 2 of glass or isotropic plastic may be sandblasted or etched to prevent the layer or layers 3 in its liquid state from flowing off. To further control drainage, the layer 3 may be deposited in areas e.g. by rough spraying to provide a dot formation or by filling the interstices between glass beads covering and stuck to a plate 2. In Fig.5 several different coatings 3, 3', 3" are applied to etched areas on 2, the viewer 6 scanning the system through analyzer 4 to determine whether uniformity of birefringence exists. The chemical of the layer 3 may be wetted before application, or the crystals of 3 may be dissolved by the moisture in the air to provide another visual indication of the humidity level. Various thickeners, materials to increase sensitivity to humidity, and dyes may be added to the crystals of the layer 3.

Title: Improvements in or relating to mechanism for feeding material from rolls to receiving machines
IPC: B65H23/06
Filed: 1923-09-26
Abstract: 225,005. Igranic Electric Co., Ltd., (Cutler-Hammer Manufacturing Co.). Sopt. 26, 1923. Acting on flat sides of discs; applied by speed regulators; electric and magnetic. - Material drawn from a supply roll is tensioned by a friction-member engaging a part rotated by the roll, the distance of the frictional engagement of the parts from the axis of rotation being automatically regulated in accordance with the diameter of the supply roll so as to maintain the tension of the material substantially constant. Fig. 2 shows a roll mounted between spindle heads 24, 30 geared to a shaft 77 carrying a friction disc 75 acted on at right-angles by a friction disc 76, Fig. 3, counted so as to move automatically nearer the centre of the disc 75 as the roll diminishes in diameter. The disc 76 is rotated, through chain and bevel gearing, by, and at a speed proportional to, the drawing-off machine. The disc 76 is carried by an arm 80, Fig. 3, fixed on the left-hand end of a shaft 58 which shaft also carries, on arms 55 and 57, web-renewing mechanism including rollers 50 and 51 which rest on the periphery of the web roll and by gravity follow it as it diminishes in size. As the disc 76 is thus gradually moved in nearer the centre of the disc 75 the frictional torque diminishes and the tension on the web remains constant. The tension may be varied by adjusting the pressure of the disc 76 on the disc 75 by means of a hand screw 97, Fig. 3, forcing a spring 95 against the arm 80 which can rock longitudinally for this purpose. The tension is taken off when the webremoving mechanism is acting by energizing electromagnets 91 which attract the arm 80 and so withdraw the friction wheel 76 from contact with the disc 75. When a new web roll is joined to the exhausted web and brought into action, the friction wheel 76 is automatically swung over to bear against the friction disc 75 of the new web spindle. To provide quick stopping of an active web roll to prevent overrunning, the supporting bracket 21, Fig. 2, of each roll-carrying frame has an electromagnetic winding 101 which attracts spring friction discs 102 on shafts 77 so that the discs rub against a fixed friction ring. such action retarding the shaft 77 and through gearing 79 and 78 braking the roll.
Patent GB-775081-A (GB)
Title: Improvements in polyester resins
IPC: C08G18/42
Filed: 1955-08-19
Abstract: A polyester is made by reacting together (1) 25 to 56 equivalents per cent of terephthalic acid and/or isophthalic acid (or ester-forming derivatives thereof); (2) 15 to 46 equivalents per cent of ethylene glycol and (3) 13 to 44 equivalents per cent of a saturated aliphatic polyhydric alcohol having at least three hydroxyl groups, e.g. glycerine, 1:1:1-trimethylol ethane, 1:1:1-trimethylol propane, pentaerythritol, sorbitol, mannitol, diglycerol or dipentaerythritol. The ester-forming derivatives may be the acid chlorides or half esters but are preferably the dialkyl esters.  Polyesterification is effected by heating the reactants for 2-6 hours from room temperature to 200 DEG  to 270 DEG  C. and maintaining the reactants at the final temperature for 2-4 hours and is preferably effected in presence of xylene.  When starting from the dialkyl esters, alcoholysis catalysts are preferably used, e.g. lead oxides, lead acetate, zinc oxide, cadmium acetate, cuprous acetate, zinc acetate, magnesium acetate, beryllium acetate, stannic acetate, ferric acetate or nickel acetate. The reaction is terminated by adding a solvent, e.g. cresols, xylenols, polyhydroxy benzenes, petroleum hydrocarbons, or xylenes and other polyalkyl benzenes, e.g. "Solvesso" (Registered Trade Mark) 100 or 150.  The resulting solutions may be used for insulating conductors (see Specification 775,082, [Group XXXV]) in which case the resin is cured on the wire by adding curing catalysts, e.g. zinc octoate, cadmium octoate, aromatic diisocyanates or aliphatic diisocyanates.  The resins may also be used as slot insulation in dynamo-electric machines, as the dielectric medium in capacitors, in paint or varnish formulations, as moulding powders in admixture with fillers, e.g. wood flour, diatomaceous earth, carbon or silica, or as impregnants or bonding materials for metallic and fibrous laminates. Minor amounts of other resins may be added, e.g. melamine-formaldehyde, aniline-formaldehyde, urea-formaldehyde, silicone, cellulose acetate, polyamide, vinyl, ethylene, styrene or butadiene/styrene resins.
