Title: Improvements relating to methods of and means for effecting reproduction from successive sound and/or motion picture records
IPC: G03B31/00
Filed: 1930-09-12
Abstract: 366,967. Kinematograph projection. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Cook, E. D. ; 37, Mitchell Avenue, Flushing, New York, U.S.A.) Sept. 12, 1930, No. 27321. Convention date, Sept. 12, 1929. [Class 97 (i).] Change-over from one projector to another is effected with the aid of auxiliary sound records on the two films, the sound records being identical and each producing a note of gradually increasing or decreasing pitch. The projectors are driven by separate synchronous or other constant speed motors 7 through differential gearing in casings 8. The films may carry sound records for reproduction during projection, and the images and sound record on the trailing end of one film are duplicated on the leading end of the other. Reproduction from the auxiliary records 27, 27<1> may be simultaneously effected by a loud speaker 36 in the operator's cabin, or separately by the two earpieces of a telephone worn by the operator. When one film is nearly run out, the operator receives a sound or other signal to start the second projector. When the second projector is running at full speed, he hears the notes from the two auxiliary sound records. If they are not identical, a beat note is heard, and, by turning the handle 18 to adjust the differential gearing 12 .. 15 of the second projector, the frequency of the beat note may be reduced to zero ; change-over may then be effected.

Patent GB-895503-A (GB)
Title: Sulfur recovery process
IPC: C01B17/05
Filed: 1958-08-29
Abstract: Hydrogen sulphide and water vapour are removed from a gaseous mixture by contacting with sulphur dioxide in a 90-99% aqueous solution of an inert, neutral, stable, organic solvent having a vapour pressure not more than 10 mm's. Hg., and a solubility in water not less than 2%, at 20 DEG  C., and containing at least 2 atoms of at least one element other than C and H, at least one of which is O or S, and not more than 2 vicinal OH radicals.  The water is absorbed by the solution and S particles are precipitated.  A number of organic solvents are specified including the glycols, e.g. diethylene, triethylene, or propylene glycol, or the ether or ester derivatives thereof.  The H2S-containing gases, e.g. sour natural gas, may be reacted with SO2 in the presence of the aqueous solution of the organic solvent in various ways, e.g. the SO2 may be dispersed in the sour natural gas in an absorption tower and the combined gaseous mixture absorbed in a descending stream of the aqueous solution of organic solvent, or the SO2 may be dissolved in the aqueous solution of organic solvent and the resulting solution, which should preferably contain less than 10% wt. of SO2, is contacted with a stream of sour gas ascending the absorption tower, or various combinations of such processes may be employed.  The Specification refers to several plants for the removal of H2S from gaseous mixtures in detail with reference to accompanying drawings.  The suspension of sulphur may be agglomerated by heating to melt the S, and the S is removed from the spent aqueous solution by decantation.  Spent aqueous solution, after regeneration to remove SO2 and excess water absorbed, is recycled to the process.  The SO2 may be formed by oxidizing one-third of the H2S in the gas mixture.

Title: Improvements in and relating to raising platforms or lifts particularly for motor vehicles
IPC: B66F7/20
Filed: 1945-10-25
Abstract: 601,090. Lifting platforms. JONGERIUS N. V., J. Oct. 25, 1945, No. 28167. Convention date, Dec. 1, 1943. [Class 78 (iii)] A device for lifting loads such as motor vehicles, comprising a platform supported on two or more extensible posts each of which consists of a plunger connected to the platform and adapted to be moved under pressure in a cylinder, and a controlling device provided for each post or the outer post of more than two aligned posts for maintaining the platform automatically in a horizontal position, said device being provided with valves which control the pressure fluid within a conduit connecting the cylinder with a reservoir containing fluid under pressure, is characterized in that each controlling device comprises two valves, one of which is operated by the difference of pressure between two points of the pressure fluid system and the other by means dependent on the inclination of the platform, and that the conduit intermediate the two valves includes two branches, one branch being closed during the upward movement of the plunger and the other during its downward movement by the first-mentioned valve and the cross-sectional 'area of the branch not closed by this valve being controlled by the second valve. In the embodiment shown, the platform 1 is supported on two posts, each comprising a plunger 3 and a cylinder 4 containing liquid and interconnected by conduits 6, 7 and a control device 8, the plunger being operated by compressed air introduced through a conduit 9. The conduit 11 in the device 8 connecting the conduits 6, 7 is provided with branches 12, 13 controlled by slide valves A, B, the valve A comprising spring-controlled valve members 14, 15 the latter of which forms the end of a chamber connected by a conduit 10 with the conduit 9, and the valve 13 being connected to the platform by a rod 20 and lever 21. When the platform is raised by introducing compressed air into the plunger 3, liquid is driven through conduit 6, the control device 8 and conduit 7 to the cylinder 4. Since the pressure in the channel 9 is higher than that in the cylinder, the valve members 14, 15 are raised so as to close the passage 13 and open the passage 12 and the cross sectional area of this latter passage is then controlled by the valve B, such control depending on the inclination of the platform. If the post lags behind, the platform becomes inclined as shown in Fig. 1 and the valve B forced down so as to open the passage 12. In the other post the valve B will be raised so as to close the corresponding passage 12. Thus the supply of liquid to the posts is adjusted so as to move the platform to a horizontal position.
