Patent GB-869140-A (GB)
Title: An improved method and apparatus for forming film or sheeting
IPC: B29C48/08
Filed: 1957-09-10
Abstract: <PICT:0869140/IV (a)/1> A composite film is formed on the surface of a continuously moving support by continuously extruding a solution of a film forming material from a stationary hopper on to the surface of the moving support, the viscosity of the dope and the distance of the outlet of the discharge slot of the hopper from the support being such that a layer of dope issuing from the slot forms a self-sustaining and unsupported ribbon bridging the distance between the slot and the support, forming a bead of coating solution against one surface of the ribbon in spaced relation with the support across and in contact with which the ribbon moves in passing to the support, the coatting solution having a viscosity sufficiently low to permit the ribbon to pick up a layer of the coating solution on its surface by a bead action as it moves thereacross, and continuously feeding fresh coating solution to the bead at a rate commensurate with the rate at which it is taken from the bead on the surface of the ribbon to maintain the bead at a given size. As shown in Fig. 2, a high viscosity film dope 11 which is to be cast is extruded under pressure from a hopper (not shown) from a narrow extrusion slot 13 in the form of a ribbon R on to a supporting surface 14, such as a chromium plated wheel or an endless band, continuously moving across the exit end of the hopper.  The exit end of the slot 13 is preferably at least 0,030 inch from the supporting surface, and a spacing of 0,060 inch has been found satisfactory.  A low viscosity coating solution 21 is allowed to flow by gravity from a second hopper (not shown) through a metering slot 22 which is inclined towards the slot 13 and whose exit end is spaced from and connected to one edge of the exit end of the slot 13 by a wall or surface 24.  A bead 23 of the coating solution 21 issuing from the metering slot 22 is formed and maintained in contact with the upper surface of the ribbon R by surface tension forces between the solution and the surface 23 and the lip 25 of the metering slot.  In a second embodiment of the invention the coating solution is supplied to the lower surface of the ribbon R and directly engages the supporting surface 14, while in a third embodiment both surfaces of the ribbon R are supplied with coating solution simultaneously.

Title: Automatic safety switchgear for motor vehicles
IPC: H01H73/30
Filed: 1958-09-05
Abstract: 899,705. Thermal switches; automatic circuit-breakers. TAPPERT, H. J., and GERLACH, H. Sept. 5, 1958 [Aug. 22, 1958], No. 28618/58. Class 38 (5). An automatic overload cut-out for motor vehicles comprises a bimetal strip carrying, the load current and arranged to deform on overloading to cause opening of contacts in the circuit and release of a push-button which moves to a position where it holds the contacts open until the push-button is returned, a second circuit feeding a signal being closed when the load circuit is opened. In one form, Fig. 2, the bimetal 2 carries a contact normally engaging a fixed contact on terminal 3 connected to the load 9, which may be a vehicle lamp. On overload, bimetal 2 deflects downwards to open the contacts and release a spring-urged button 4 which moves to prevent return of the bimetal. A second bimetal 5 is connected in parallel with a part of bimetal 2 and the current to the load normally keeps bimetal 5 deflected to separate contacts in circuit with an indicator 8. If the load circuit contacts open, or if the load 9 fails, bimetal 5 cools and the indicator 8 is energized. The indicator contact may alternatively be carried by the bimetal 2, Fig. 1 (not shown), so as to be closed thereby when the load circuit is open. In a further arrangement, Fig. 3 (not shown), the main bimetal deflects to release the push-button which moves to release the contacts. The indicator may be a lamp or other visual means, or an acoustic device.

Title: Improvements in or relating to the photographic production of coloured pictures
IPC: G03C7/20
Filed: 1927-10-27
Abstract: 279,882. Witte, W. Oct. 28, 1926, [Convention date]. Colour photography. - Two plates or films of different colour sensitivity are simultaneously exposed, and from the two negatives two diapositives are printed. From different combinations of two of the four plates, so selected that in each combination there is a common densitv for one primary colour, three printing plates for the primary colours are obtained. As a particular example an orthochromatic plate is superposed in front of a panchromatic plate and the combination exposed. From the orthochromatic negative I which reproduces most intensely the blue, and from the panchromatic plate II which reproduces most intensely the yellow, diapositives D1 and D2 are printed. Plate II is sensitized with bichromate and exposed through the back and also from the front through the plate D1, thereby giving a yellow printing plate G by the use of a pinatype dye. Similarly by sensitizing plate D1 and using it in conjunction with the plate D2 in the same way, a primary printing plate R for red is obtained. Similarly again from plates D2 and I a printing plate B for blue is obtained.

Title: System for the Automatic Control of Strip Thickness
Inventor: KUNIG HELMUT
IPC: G05D5/03
Filed: 1968-06-18
Abstract: 1,168,036. Automatic thickness control. HANSEATISCHE MOTOREN-G.m.b.H. June 18, 1968, No.28852/68. Heading G3R. In a system for automatically controlling the thickness of moving material, a feeler responsive to thickness adjusts the axial position of pins arranged in a circle about the axis of a rotating plate, the position of the ends of the pins being detected by photo-electric means controlling thickness. In Fig.3, a rod 8 moves axially in response to variations in thickness of a moving web of fibres (not shown) so that attached jaws 5 and 7 adjust the axial position of pins 4 arranged in a circle in a rotating plate 1. The ends 10 of the pins, which are enlarged, pass between a light source 12 and a photo-cell 11 so that the amount of obturation, and hence photo-cell output, is dependent on thickness with a lag dependent on the relative location round the circle of the photocell and jaws 5 and 7. The photo-cell output controls, through an amplifier 15, a solenoidoperated valve 17, and a hydraulic servomotor 20, the setting of a variable speed transmission 25 correcting thickness variations. Servomotor 20 also adjusts the axial position of the light source 12 and photo-cell 11 to provide follow-up. An electric servomotor operating a screw and nut adjuster may replace the hydraulic servomotor.

Title: Process for the production of esters of bis-[4-hydroxycoumarinyl-(3)]-acetic acid
IPC: C07D311/48
Filed: 1952-11-17
Abstract: Esters of bis-[4-hydroxycoumarinyl-(3)]-acetic acid are prepared by reacting a dialkoxy acetic acid alkyl ester with 4-hydroxycoumarin in highly concentrated formic or acetic acid, if necessary in presence of a very slight amount of mineral acid, e.g. concentrated sulphuric acid or hydrogen chloride.  Dimethoxy acetic acid methyl ester and diethoxy acetic acid methyl, ethyl, propyl and butyl esters are suitable dialkoxy acetic acid esters. The example describes the preparation of bis-[4-hydroxycoumarinyl-(3)]-acetic acid ethyl ester from 4-hydroxycoumarin and diethoxy acetic acid ethyl ester.  Bis - [4 - hydroxycoumarinyl - (3)] - acetic acid is obtained as a reaction product if less highly concentrated acetic or formic acid is used as the solvent.  Esters of the acid <FORM:0710631/IV (b)/1> are formed when greater amounts of sulphuric acid or hydrogen chloride are added to the glacial acetic acid solvent.
