Title: Improvements in and relating to apparatus for recording and reproducing sound
IPC: G11B15/22
Filed: 1941-02-28
Abstract: 544,760. Sound recording and reproducing apparatus. W.A.F. CO., Ltd., and ALLEN, H. H. Feb. 28, 1941, Nos. 2746 and 4531. [Class 40 (ii)] In an apparatus for mechanically recording sound on films, the recording head 6 is so mounted that it cannot move towards or away from the film 1 but only transversely thereto, whereas the film bears at the recording point against a cam 4 which can be turned to adjust the depth of cut, and the recording head is automatically traversed across the film during the travel of the film. As shown, the cam 4 is a circular segment mounted slightly eccentric-' ally on a shaft 8 which can be turned by a handle 13 to various positions indicated by a pointer 14 on a dial 15. When the circular segment faces the recording head, the stylus 12 is in contact with the film and the depth' of cut can be regulated by the rotational setting of the segment. When the segment is turned away from the recording head, space is left to permit removal and insertion of stylus which abuts against a stop in the recording head to ensure correct position. The recording head is mounted on and guided by a rod 10 and lead screw 11. The film 1 is an endless one with a twist permitting recording on opposite sides alternately in a number of parallel or slightly oblique tracks in continuation one of another. The film passes through a gate 3 to the cam 4 and thence upwards to a driving sprocket over which is situated a reproducing head 7. The sprocket 5 is driven through suitable gearing by a motor 16 which also serves to drive the lead screw 11 through reducing gear 17, change speed box 18, and clutch 19. The change speed box enables the pitch of the tracks on the film to be varied or compensation to be made for different lengths of film. The traverse of the recording head is indicated by a dial 21 geared to the screw 11 and movable behind a window 22 in the panel 2. The gate 3 is provided with two pairs of contact rollers 25, 26, to co-operate with contacts on the film to determine two stopping positions of the film, one for recording and one for reproducing. Various operations of the apparatus are controlled by the rotational setting of the shaft 8 by the handle 13. Normally when the apparatus is out of action, the shaft is set with its pointer 14 at the point " Off " on the dial 15, Fig. 6. To start recording, the pointer is turned to "Stop Record"; this causes the motor to drive the film until the contact on the film automatically stops the drive. The pointer is then turned to " Cut " ; this starts the motor again, but on a circuit independent of the film contact, and also operates the clutch to transmit motion to the lead screw. Finally the pointer is turned to the desired " Cutting Depth " graduation. For reproduction, the pointer is moved from " Off " to " Stop Repro " and then to " Reproduce." Specification 544,764 is referred to.

Insoluble metal oxide particle coated with a phosphate or an oxide or hydrous oxide of titanium, aluminium, cerium, silicon, zinc or zirconium are given a further coating of hydrous metal oxide by (a) mixing them with a solution made by raising the pH of, and then heating an aqueous solution of hydrolysable metal salt to form and re-dissolve a precipitate, and then (b) precipitating hydrous metal oxide upon the particles by, e.g. raising the pH of, or passing an electric current through, the solution. The coated insoluble metal oxide substrate particles are those that have been made by either (1) oxidizing a metal compound in the vapour phase in the presence of the insoluble metal particles to deposit a coating of an oxide of titanium, aluminium, cerium, silicon, zinc or zirconium, or (2) by mixing an aqueous dispersion of the particles to be coated with a hydrolysable compound of titanium, aluminium, cerium, silicon, zinc or zirconium or a phosphate or phosphoric acid in aqueous solution to which alkali has not been added, and changing the pH to deposit a hydrous oxide or a phosphate coating on the insoluble metal oxide particles. In one embodiment, the insoluble metal oxide is TiO 2 , and the coating is hydrous Al 2 O 3 . The initial aqueous solution may then contain 0À5-200 g./1. of an Al salt such as the trichloride, trinitrate or sulphate. Precipitation may be effected by adding sufficient water-soluble alkali to give a ratio of metal to OH group in solution of 1 : 0À2 to 1 : 2À8, and the precipitate may be redissolved by heating at 25-90‹ C. for 5-200 mins. The solution may then be diluted. Precipitation of the final coating, after dispersion of the TiO 2  particles, may then be effected by raising the pH over 0À25-10 hours to at lest 5À7 at 10-50‹ C. Further alkali may be added to give a pH up to 8À5. The hydrous oxide or phosphate coatings may comprise 0À5- 10% by wt. of the TiO 2 . In examples, a final coating of hydrous Al 2 O 3  is provided on rutile TiO 2  particles bearing initial coatings of (1) Ti and Al oxides; (2) Si and Al oxides; (3) Zr and Al oxides on an Al oxide subcoat.

Title: Improvements in and relating to pressure-fluid control devices
IPC: F16K11/065
Filed: 1959-01-28
Abstract: 890,657. Fluid-pressure servomotor-control systems; valves. ETABLISSEMENTS GROSDEMOUGE. Jan. 28, 1959 [Feb. 3, 1958], No. 3097/59. Class 135. [Also in Group XXXI] A valve consisting of relatively movable sleeve and plunger elements 16, 17, has a spring-loaded sleeve 73 interposed between co-operating ports 18, 23 to provide rapid opening. The arrangement is such that the sleeve 73 remains overlying the ports 23 until, due to relative movement between the elements 16, 17, the ports 18 communicate with an annular chamber 75 whereupon pressure-fluid supplied to the ports 18 through a passage 60 is effective on the end of the sleeve to move it against its spring 74 and permit full communication between the ports 18, 23. The valve may be used for controlling a jack for raising and lowering a plough carried by a tractor, the sleeve 16 being movable by a control lever 45 and the plunger 17 by a cam follower 48 carried by a lever 49 and coacting with a cam 51 adjustably positioned on a shaft 34 of the lifting arm for the plough. The lever 49 has a connection with the " third point " of attachment of the plough through a slotted link 54. When the elements 16, 17 are relatively positioned as shown, pressure-fluid entering the housing at 65 passes through a check valve 63 to the jack causing movement of the jack until the cam 51 brings the port 23 into communication with the port 18 when the pressure-fluid is passed through the hollow plunger 17 to exhaust 26 and the jack is held stationary by closure of the check valve 63. To permit the jack to move in the opposite direction the sleeve 16 is moved to exhaust the jack through a passage 61 and ports 82, 24. The latter ports may also be associated with a spring-loaded sleeve for giving a rapid opening. A safety valve 64 is provided.
