Title: Improved mechanism for raising and lowering and fixing windows of vehicles
IPC: E05F11/38
Filed: 1938-03-23
Abstract: 518,758. Vehicle-window regulators. BROOK, E. J. L. March 23, 1938, Nos. 20381/39 and 29495/38. Divided out of 512,925. [Class 20 (iii)] A lever mechanism for operating sliding windows of vehicles comprises a spring fitted between the operating-lever and a supporting bracket, the pressure of the spring being exerted at varying points on the lever in relation to its fulcrum in the 'swinging movements of the lever. As shown, the lever element consists of a parallel-ruler frame 1 pivoted at its upper end to the movable window-supporting bracket 2 and at its lower end to a fixed door - bracket 6. Centrally-pivoted on the bracket 6 is an arcuate-piece 4 against the inner edge 4a of which an extension 7a of the arm 7 of the leverframe wipes. A balancing-spring 19 operates in tension between the upper end of the'leverarm 25 and a link 21 which is pivoted at 22 on the fixed bracket 6, a roller 23 on the link 21 bearing on the lever 25. If the lever system is moved downwardly from the position shown, the spring will be stretched and its increased pull is compensated by the travel of the roller 23 towards the pivot 26 of the lever 25. The device is operated by a handle 17 and locked on release of the latter by the engagement of a pair of rocking jaws 10, 11 mounted on links 8, 9 which are pivoted on the lever 7, with the outer edge 4b of the arcuate piece 4. Fast with the handle 17 on the spindle 3 is a cam-disc 18 having pairs of shoulders 18a, 18b and 18c, 18d which are adapted successively to engage a slide 14 and a lug 28 on the lever 7. The slide 14 is formed with taper ends 15, 16 co-operating with complementary tapers on the links 8, 9 to spread the latter against the pull of a spring 13. The jaws 10 are thereby released and, according to the direction of movement of the handle 17, one or other of the shoulders 18c, 18d abuts the lug 28 to effect the desired movement of the lever system.

Title: Improvements in or relating to sound recording systems
IPC: G11B7/00
Filed: 1935-07-19
Abstract: 459,896. Optical sound recording apparatus and processes. ROUND, H. J., Westfield, Muswell Hill, SWANN, F. P., 7, Putney Park Avenue, and ROUND, F. A., 286, Watford Way, Hendon, all in London. July .19, 1935, No. 20642. [Class 40 (ii)] A method of effecting noiseless optical sound film variable area recording consists in bring- ing " cutting edges " into and out of use in pairs in accordance with the strength or level of the sound to be recorded whereby the effect, as regards reproduction, of any one of said " cutting edges " in the pairs is balanced out by the effect of the other cutting edge " in the same pair, there being always either one or some odd number of " cutting edges " in use. Fig. 3 shows a length of sound film record on which there are five parallel " cutting edge tracks " 2, 2a, 2b, 2c, 2d, and three exposed portions or tracks 1, 1a and 1b. The main track 1, which is never switched out, is bounded on one side by the line 2, the lines 2a, 2b defining track 1a and the lines 2c, 2d defining track 1b. According to the invention, tracks 1b and 1a are faded in and out as shown at X or shaped in and out, Fig. 4 (not shown), as required in dependence on sound level without altering the volume of reproduced sound. The apparatus for carrying the invention into effect may comprise a mask which is inserted in the path of a light beam which is reflected by an oscillograph mirror and projected and focused as a thin intense line of light on to the film. This mask is preferably in the form of a thin strip of mica or film with opaque areas having edges E ... Ed, Fig. 5a, photographically produced thereon. A moving coil fed with rectified currents derived by rectifying the signals to be recorded is attached to the mask which is thereby moved relatively to the light beam as shown at P, Q and R so as to vary the number of edges in the path of the recording light beam. When the mask is moved so that the light beam is in the position shown at P on ordinary variable area sound record results ; with the light beam in the position shown at Q and R additional sound tracks are recorded. The arrangement is such that the additional track are successively faded out as the amplitude of the sound to the recorded increases. Preferably, the end edges M, N are not sharp, but are shaded off so that the corresponding sound tracks are gradually faded out as the mask is moved to bring the light beam into and out of the positions P, Q, R.

Patent GB-206842-A (GB)
Abstract: 206,842. Automatic Telephone Manufacturing Co., Ltd., (Automatic Electric Co.). May 1, 1923. Drawings to Specification. Automatic exchange systems.-An impulse sender, forming part of a register-controller, comprises an interrupter which on the one hand builds up a relay counting-chain, energizing only one relay at each opening and closing of its circuit, and on the other hand controls the transmission of impulses to an outgoing circuit until a marked counting-relay is energized. The counting-relays are of two-step type, each relay being partly energized when its circuit is closed and bringing into play a second winding which is short-circuited as long as the original energizing circuit remains closed but afterwards brings about full energization. The system which is described as embodying the invention is the same as the system described in Specification 200,484.

Title: Method of producing aluminium oxide
IPC: C01F7/20
Filed: 1936-07-28
Abstract: In a process comprising the decomposition of clay, bauxite, leucite, or other aluminiferous material with an acid such as hydrochloric acid and thermal decomposition of the salts obtained into alumina and acid vapour, the hot acid gases from the thermal decomposition together with water are caused to react with the raw material to form a salt solution, insoluble residues, and steam, and the separated solution is evaporated substantially by means of said steam, thereby utilizing the reaction heat evolved. The water added in the decomposition of the raw material preferably consists of washing water and condensation water obtained in the process, and evaporation of the salt solution is preferably effected in one or more stages in a vacuum appliance. When hydrochloric acid is used conditions are preferably so regulated that the acid does not exceed a concentration of 20 per cent.  The raw material may be decomposed in a rotary cylinder through which the acid and material pass in the same direction or in a trickling tower.  Iron present in the acid solution may be removed by precipitation, or the solid aluminium chloride may be treated with a solvent for iron chloride such as ether or acetone, or be washed with a concentrated solution of aluminium chloride, the resulting solution, after reduction of iron if necessary, being reacted with aluminium sulphate to form sulphates less soluble in water than aluminium chloride.
