Patent GB-852303-A (GB)
Title: Improvements in or relating to control devices for maintaining a rectified current at a constant voltage
IPC: H02J7/12
Filed: 1958-05-22
Abstract: 852,303. Automatic voltage control systems. SOC. DES ACCUMULATEURS FIXES ET DETRACTION. May 22, 1958 [May 28, 1957], No. 16491/58. Class 38 (4). In a voltage control system a saturable reactor 4 has a winding 4a in series with the A.C. supply to a bridge rectifier 3. A winding 4b carries the rectified output current and a control winding 4c is connected to the output terminals 7, 8 in series with a constant voltage element 5. The control winding 4c is wound to give a flux opposing the saturating flux due to the winding 4b and the output voltage is maintained at a value slightly greater than that of the constant voltage element 5 which comprises a battery of pressurised alkaline cells in a state of overcharge. A floating battery 11 having an equal number of cells to that of the constant voltage element 5 is connected across the output terminals together with a surge-limiting capacitor 10. It is stated that the control system may be used from a poly-phase supply by employing a saturable reactor 4 in each phase. The constant voltage element 5 may comprise Zener diodes. Specification 715,903 is referred to.

Patent GB-481588-A (GB)
Title: Method of forming articles from plastic material
IPC: B29C41/04
Filed: 1936-06-12
Abstract: 481,588. Moulding pipes &c. by rolling. FAIRWEATHER, H. G. C. (Haveg Corporation) June 12, 1936, No. 16500. [Class 87 (ii)] In forming articles from plastic materials such as synthetic or natural resin, asphalt, cement or sodium silicate with or without fillers such as fibrous asbestos, the material is applied to a support which is rotated and a small, freely rotatable roller 5 is applied so that a relative traversing movement is effected between the material and the roller. The support may be a mandrel 1 mounted on a lath,e 4 and the material may be placed between collars 3 on the mandrel. A pipe 6 may thus be formed by the roller 5. In another form, the material is applied to the interior of a fixed cylindrical two-part mould and the roller mounted within the mould on a support which rotates with a mandrel projecting within the mould. In another form, the support may be a flat disc and the roller may be applied to mould curved surfaces or pipe-ends. The shaped mass is hardened as by baking and the support removed. Pipes, tanks and other equipment, when made from synthetic resin in this way, are rendered corrosion-resistant. The resin may be a phenol-, urea-, or thioureaformaldehyde, polyhydric alcohol - polybasic acid, phenol-furfural or shellac, asphalt, cement or sodium silicate may be used. The filler may be fibrous asbestos, graphite, carbon black, quartz powder, slate powder, cellulose, or wood flour. Examples of mandrel and roller speeds for different diameters of pipes are given. The roller may be heated.
Patent GB-644193-A (GB)
Title: Improvements in or relating to automatic-feed weighing apparatus
IPC: G01G13/00
Filed: 1948-06-19
Abstract: 644,193. Automatic - feed weighers. SIMON, W. G. June 19, 1948, No. 16514. [Class 143] Apparatus for weighing-out flour or other powdered material has two sets of electrical contacts operated in succession by descent of the weigh-beam, the first controlling an electrically-actuated dribble gate 12, to reduce the rate of delivery from a supply hopper 1 to a weigh-pan 9 and the second stopping a motor 5 driving a delivery conveyer 2. In the apparatus shown, the conveyer 2 forms the base of the supply hopper 1 and delivers material through an aperture 8 in a partition 7 into the weigh-pan 9. The dribble gate 12 is on a lever 13 and is operable by a solenoid 14 to control the aperture 8. As the required weight is approached and the weighbeam 10 supporting the weigh-pan 9 descends, one of a pair of lugs 15 on the beam opens contacts to de-energisd. the solenoid 14 so that the shutter 12 lowers and restricts the flow. When the full weight is reached, the further movement of the weigh-beam causes the second lug 15 to open further contacts to de-energise and brake the conveyer motor 5 so stopping the feed. A discharge gate 18 is then opened by manually operating a pullrod 26; the returning weigh-beam re-sets the motor and solenoid contacts but the motor circuit remains open at safety contacts until the discharge gate 18 is reclosed. A push-button or automatic control may be employed for the discharge gate in place of the pull-rod 26. A motordriven thruster may replace the solenoid 14. Indicator lights show when the conveyer motor is running and when the feed hopper is nearly empty.
Patent GB-166271-A (GB)
Abstract: 166,271. Drey, O. Oct. 4, 1919. Coating fabrics in long lengths.- Discharge and resist effects are produced on pile fabrics by applying colouring-matter to the back of the foundation of the fabric and forcing it, or allowing it to percolate through the foundation and into or partially into the pile according to the effect desired. The foundation 3 of the fabric passes over a perforated steam pipe 2, and thence over a dye-applying roller 4 arranged in a trough 5. Superfluous dye is removed by a doctor 8, and the dye is forced through the foundation of the fabric into the pile by a perforated steam pipe 6. Compressed air may be employed instead of steam, and the fabric may be subjected to a number of treatments, the effects may also be varied by varying the speed of traverse of the fabric, the amount of dye applied, and the pressure of the steam or air employed. Reference has been directed by the Comptroller to Specifications 13000/90 and 5400/93, [both in Class 101, Printing other than letterpress &c.].

Abstract: 406,177. Safety razors. PAGE, M. H., 201, Graphic Arts Building, Kansas City, Missouri, U.S.A. June 12, 1933, No. 16780. [Class 30.] A hollow-ground safety-razor blade 27 rests on inner ledges 21 on side-flanges 12 and is pressed forwardly against undercut stops 24 which receive the corners of its cutting-edge, by a spring-pressed lever 34 pivoted at 31 on a base-member 11 which connects the side-flanges 12. The end of the lever is hook-shaped to conform to the thick rear-edge of the blade, which it engages centrally. The blade-supporting ledges 21 incline downwardly towards long, widely-spaced guard-teeth 16 on the basemember 11. Pressure on a finger-piece 42 of the lever 34 releases the blade, which, being unobstructed by any part of the holder, can be dropped therefrom without handling. Forward movement of the lever 34 when the blade is removed is limited by a stop 41 thereon.
