Title: Improvements in and relating to the preliminary treatment of articles made of iron or steel for cold deformation by the application of a phosphate layer
IPC: C23C22/10
Filed: 1959-08-27
Abstract: Ferrous material is descaled and phosphate coated in a single step by treatment with a solution of pH below 1.5 and containing 2-10% by weight free phosphoric acid, 0.2-2% by weight of a phosphate, an accelerator and less than 15 g./l. of iron at a temperature between 70 DEG  C. and the boiling-point of the solution, the treated material being directly dried below 200 DEG  C. without rinsing.  The concentration of the accelerator such as zinc nitrate, sodium nitrite or chromic acid is 0.1-1.0% by weight and the phosphate may be either zinc or manganese phosphate.  The ratio of free to bound phosphoric acid in the solution should be between 10 : 1 and 2.5 : 1 and in order to maintain the iron concentration below 15 g./l. oxidizing agents such as hydrogen peroxide, a chlorate, a nitrite, a nitrate, nitric acid, potassium permanganate, ozone or ozone containing air are added to precipitate the iron as ferric phosphates.  The treated material prior to drying may be treated with a second solution containing phosphoric acid, at least half of which is bound, and zinc or manganese phosphate so that the final coating contains less than 12 mol. per cent of iron phosphate.  The second solution has a preferred composition of 0.4-3% free phosphoric acid, 0.5-4% zinc or manganese phosphate and 0.1-2% accelerator, the temperature of the solution being 60-100 DEG  C.  The process may be a batch or continuous type and a mechanical descaling may be effected in the bath by means of rollers which bend the work e.g. wires or strip in three directions.  As shown in Fig. 2 a wire 12 is fed into the first phosphate bath 9 and bent by roller system 13 to remove loose scale 14 which is continuously removed from the bath.  After treatment the wire is directly dried by hot air in pipe extension 7.

Title: Improvements in or relating to draught excluders for doors and the like
IPC: E06B7/20
Filed: 1948-11-11
Abstract: 655,756. Draught excluders for doors. FLORIN, G. H. Nov. 11, 1948, No. 29371. [Class 20(iii)] A draught excluder mounted on the bottom rail of a door has a sliding presser bar which is pressed against the floor as the door closes by a rod, one end of which engages the door jamb whilst the other end engages the end of a stout, spiral, compression spring which, in turn, bears on the bar. The drawing shows a rear view of one form of the excluder. It consists of a flat casing having a central section 11 and two end sections 12 and 13 which are adjusted telescopically on the section 11 to the exact width of the door. A presser bar 18 is held in the lower part of the casing by return springs 23, whilst a spiral spring 37, held in a right angled tubular guide 36, bears on the mid point of the bar. An actuating rod 32 is slidably mounted in the upper part of the casing and bears on the spring 37 at one end, the other end passing through the end of the casing and terminating in a head 41 which, when the door closes, contacts a plate on the door jamb and is thus pushed inwardly, this movement being converted into a downward pressure on bar 18 by the spring. Since pressure is applied at the mid-point of the bar 18 by the spring, the bar can adjust itself to unevenness in the floor and can yield against any obstruction on the floor. The bar may be made in telescopic sections so that its length can be readily adjusted to suit the door width.

Title: Improvements relating to injectors
IPC: F04F5/46
Filed: 1926-11-22
Abstract: 285,963. Metcalfe, R. D., and Metcalfe, J. C. Nov. 22, 1926. Giffard injectors; controlling action.-In an exhaust steam injector automatic control valves o, j, x, Figs. 3 and 4, are incorporated for the exhaust steam and water supplies and for providing a live steam supply to replace the exhaust steam when the latter is not available. while a single steam - pipe having a valve for regulating the functioning of the injector is provided between the injector and the control position. The valve o has a delaying action for retarding the time of opening of the exhaust steam inlet valve s, Fig. 1, relatively to the time of admission of live steam through the passage b to the nozzle c, and of water through the inlet e to the space k. When working with exhaust steam, opening of the valve on the control pipe allows live steam entering at g, Fig. 3, to pass to the nozzle c and, by way of the passage h to the water valve control fitting i, j. Exhaust steam also enters at v, Fig. 3, and loads the valve w to prevent the live steam from raising the valve x. When the pressure in the space u beneath the valve o rises sufficiently the valve is opened. the steam passes to and depresses the piston q which acts through the lever r to open the exhaust inlet valve s. Exhaust steam then passes to the nozzle c and the injector functions normally. In the absence of exhaust steam the valve x is allowed to rise and seat upon the upper surface y and live steam passes through the spaces z to the passage d its flow being checked by the plug 6. A leak aperture u is provided to allow steam to escape from between the valve o and the piston q to allow the piston to rise under the action of the spring t.

Title: Improvements in and relating to substances transparent to ultraviolet light
IPC: C03C23/00
Filed: 1928-10-15
Abstract: 298,908. Corning Glass Works, (Assignees of Hood, H. P.). Oct. 15, 1927, [Convention date]. Production of metal.-Glasses which are transparent to ultraviolet rays, such as those described in Specification 263,410, are found to lose gradually this transparency on continued exposure to the rays or to sunlight. According to the invention, the lost power of transmitting the rays is restored by heating the glass to a temperature approximating to its annealing temperature. The restoration is also effected by heating the glass to a lower temperature for a time which varies according to the temperature. The Specification as open to inspection under Sect. 91 (3) (a) describes also a method of producing glass which is transparent to ultraviolet rays, the selection of materials for the batch, and apparatus to be used for melting the batch. This subject-matter does not appear in the Specification as accepted, but it forms the subject-matter of Specification 319,337.

Title: Improvements in or relating to electric luminous discharge tubes
IPC: H01J17/44
Filed: 1922-10-31
Abstract: 204,933. General Electric Co., Ltd., and Ryde, J. W. Oct. 31, 1922. Vacuum. tubes. - A vacuum tube in which a luminous discharge takes place without any source of electron emission or ionization other than the potential applied to the electrodes is provided with a control electrode, and may be employed as a rectifier, amplifier, or oscillation generator. A grid electrode and another electrode, which may be a plate or a grid, are arranged close together; the grid may serve as the control electrode and be situated within the dark space separating the cathode from the negative glow, or the grid may form the cathode, the control electrode being placed a short distance behind this. A construction for mounting the grid within say 0.5 mm. of the plate is shown, in which two sheets of mica d, e are placed at the back and front of the plate electrode c, the front sheet e having an aperture nearly as large as the plate c. Fine wire f, forming the grid electrode, is wound round the plates d, e binding them together, and a third mica sheet g may be arranged over the rear layer of wire f. The lead h to the plate c passes through the mica sheets d, g. The, tube may be filled with a rare gas. and the potential required to maintain the discharge may be reduced by using an active metal as the cathode. If the control grid is placed within the dark space of the cathode, conditions may be found such that a change in the potential of the control electrode in either direction produces a change of the same sign in the cathode-anode, current, the tube thus acting as a rectifier using both halves of the oscillation.
