Title: Improvements in and relating to methods and apparatus for measuring and reproducing bodies of all kinds by photographic surveying
IPC: G01C11/00
Filed: 1935-02-14
Abstract: 452,004. Photogrammetry. HORNER, E., 10, Am Karlsbad, Berlin. Feb. 14, 1935, No. 7398/36. Divided out of and addition to 442,854. [Classes 97 (i) and 97 (ii)] A pair of stereoscopic photographs of the object being surveyed, e.g. a terrain, are placed in projectors 22, 23, in positions corresponding to those at exposure as described in the parent Specification, and are projected alternately on to a projection plane in rapid sequence so that the observer does not perceive the interruptions. The projectors 22, 23 are occulted by shutters driven by electric motors and the projections are viewed through binoculars 29 the object glasses of which are synchronously occulted by shutters so that a stereoscopic picture of the optical model is observed. A support 1 movable over the drawing table 2 carries an index plate 3, which can be adjusted in height, and a rail 9. Two blocks 10, 11 carrying lamps 13, 14 with indicia 15, 16, may be moved in opposite directions along the rail 9 by a spindle 12 with right and left-hand threads. The spindle 12 may be coupled to the spindle 4 by which the plate 3 is moved. The rail 19 carries a pencil 8 and a motor 17 driving a shutter 18 which occults the indicia 15, 16 synchronously with the binoculars 29 and projectors 22, 23. In a plate 19 above the shutter 18 are fixed two graduated strips of milk glass on which the indicia 15, 16 appear at 15a, 16a. In use the projections are first slowly occulted and the index plate 3 raised to the point of intersection of a pair of complementary rays 5, 6, the observer alternately seeing the point to the left and to the right until the index plate 3 has been moved exactly to the height of the point when the latter appears stationary at the index 7. The position of the point may be marked on the table 2 by the pencil 8. The index plate 3 is then swung to one side so that the projections fall on to the plate 19. The occulting devices are then operated rapidly so that when viewed through the binoculars 29, the images 15a, 15b formed by the pair of rays 5, 6, on the plate 19 appear as a single three dimensional image at 35. The lamps 13, 14, which at the positions 13a, 14a give rise to a single three dimensional image at 36, are moved apart until the image 36 coincides with the image 35. The separation of the indicia 15, 16 is then a measure of the height of the point defined by the rays 5, 6. A device for examining the effect of the grain of the plate on the projected image comprises a mirror mounted on the projection table and arranged to being a sample of the projected rays to a focus in a position where the image may be examined through a magnifying lens.

Abstract: 566,135. Push-button wireless sets. PHILIPS LAMPS, Ltd. (Naamlooze Vennootschap Philips' Gloeilampenfabrieken). May 6, 1940, No. 8125. [A Specification was laid open to inspection under Sect. 91 of the Acts, Nov. 11, 1940.] [Class 40 (i)] [Also in Groups XXXVI and XL] In the selection of short-wave stations, band-spreading arrangements are automatically brought into use. As shown in Fig. 1, the depression of a short-wave button operates contact 68 to mark the short-wave position to a disc 52 coupled to the wave range switch, one of four contacts, 69 ... 72, to mark the appropriate part of the short-wave band to a disc 54 coupled to a switch for connecting auxiliary condensers 46 ... 48 to the oscillator circuit and two contacts such as 77, 78 individual to the station and co-operating with profiled discs 59, 62 to cause condenser 16 to tune the preliminary circuit to the middle of the selected portion of the short-wave band and bandspreading condenser 45 to tune the oscillator appropriately for the selection of the station. A relay 82 in series with clutch magnets 84 and 83 prevents the setting of the tuning condenser until the range switches have been set and a relay 90 delays the setting of the band-spread condenser until condenser 15 has been set. In a modification, Fig. 2 (not shown), the preliminary circuit is tuned by fixed condensers connected up at the same time as the fixed condensers in the oscillator circuit and the ordinary oscillator-tuning condenser is used as the band-spreading condenser. In a further arrangement, Fig. 3, in which the buttons act mechanically, the operation of a short-wave button causes the latching plate 200 to release a disc 152 coupled to the wave-range switch which is then moved to the short-wave position, operates switches 98, 41 and 42 in accordance with the position of an adjustable member such as 209 to select the appropriate part of the short-wave range in the preliminary and oscillator circuits and finally sets the bandspread tuning condenser 45 by means of an adjustable member 208. The normal tuning condensers are only operated by the long and medium-range buttons such as 213.

Title: Improvements in or relating to the preparation of procaine penicillin
IPC: C07D499/00
Filed: 1949-03-25
Abstract: Procaine penicillin is produced by precipitating procaine penicillin from its solutions by means of a salting out agent and recovering the precipitated procaine penicillin.  For aqueous solutions the salting out agent is a water-soluble inorganic or organic salt, e.g. sodium chloride and procaine hydrochloride. Ammonium salts decompose the procaine penicillin and are therefore unsuitable.  Procaine may be used with organic solutions of procaine penicillin, e.g. chloroform solutions.  The procaine penicillin obtained from impure penicillin solutions may be purified by treatment with solvents such as acetone. Specifications 651,412 and 661,272 are referred to.
