Filed: 1938-12-19
Abstract: 522,054. Lactose. LAVETT, C. O. Dec. 19, 1938, No. 36965. [Class 127] [Also in Group III] Whey comprising the residue remaining after casein -has been removed from milk in the manufacture of cheese is concentrated and dried to obtain a product comprising chiefly beta lactose crystals by concentrating the whey to such an extent as to prevent free movement of crystals therethrough, seeding the concentrate with dry beta lactose crystals, and heating the solution to effect simultaneous drying and crystallization of the lactose. The whey is preferably concentrated to 30-50 per cent. solids in a multi-stage vacuum concentrator 1, 5, 9 and is then discharged into a steam jacketed storage tank 12, from which it is pumped to rotary steam heated drum dryers 21, 22 rotating upwardly from their point of contact to which the whey is fed by a pipe 15. A thick layer of whey is thus picked up by the drums and, after concentration to 70-90 per cent. solids, is removed by scrapers 25 and fed to a final pair of drum dryers 30, 31 which rotate towards their point of contact. Automatic seeding of the concentrate on these drums is effected by arranging the scrapers 32 so that only the top layer is scraped off and a layer of lactose crystals always remains on the surface of the drums. The seeded surface is heated to above 199.4‹ F., e.g., to 250-287‹ F. to insure that the lactose crystallizes in beta form, a non-caking stable product, which does not discolour on standing, being obtained.

Abstract: 1,069,568. Photographic process. RANK XEROX Ltd. Sept. 16, 1964 [Sept. 19, 1963], No. 37809/64. Headings G2C and G2H. Photographic images are prepared by imagewise exposing a layer of ZnO in a film forming organic compound to U. V. radiation having a wavelength in the range 350-380 mÁ, whereby the ZnO photo-catalyses an imagewise irreversible chemical change in the layer, and developing the latent image thus formed. The chemical change may result in a change in dye absorbtion or electrical conductivity in the exposed areas and the latent image may be developed by treatment with a dye solution, electrolytically, or by charging the layer and dusting it with a toner power. The latent image may be fixed by coating the layer with a solution of a compound which absorbs U.V. light. Specified film forming compounds are alkyd resins, polyvinyl acetate and linear polyesters.

Title: Pulse-modulated oscillation generator
IPC: H03K3/78
Filed: 1946-12-24
Abstract: 619,802. Pulsing carrier frequencies. HAZELTINE CORPORATION. Dec. 24, 1946, No. 37898. Convention date, Jan. 4. [Class 40 (v)] In a pulse-modulated tube generator, change of frequency due to change of pulsing rate is avoided by providing means for integrating the pulses and utilizing the resulting voltage to modify the heating effect at the tube electrodes and at associated elements. As shown in Fig. 1, the pulses are applied through a transformer 30 across anode and cathode of a triode tube 10 which is back-coupled to produce oscillations in the tuned circuit 11, 12 when the pulses render the anode positive relative to the cathode. A control triode 25 is connected in series with the oscillator valve 10 across the H.T. supply 26. The applied pulses are rectified'by a diode valve 43 and integrated by a condenser 41 and shunt resistance 40, the resulting voltage on the condenser 41 being applied through a low-pass filter 44, 45 across the grid and cathode of the valve 25. If the pulse frequency rises, the grid of valve 25 becomes increasingly negative and cuts down the anode current, thus avoiding a rise in temperature which would otherwise occur at the anode of the tube 10. In a modified circuit, Fig. 2, the control valve 25 is omitted, and the control of anode and grid current is effected by an integrating circuit 40, 41 in the cathode lead. The tuned circuit 11, 12 may be replaced by a cavity resonator or line section.

The inner tubular member may be formed by helically winding a metal strip corrugated by rollers and wound, as shown, with interlocking edges or in accordance with Fig. 3 (not shown) with an interlocked and folded over seam. The inner tube together with a wrapping of sound absorbing material may be fed through a hollow mandrel 17 around which is formed the outer tube by helically winding overlapping metal strip 16, the outer tube then being corrugated in a reverse direction to the winding direction by formers 19 and 20 in co-operation with threads on the end of mandrel 17. The corrugation pitch is then reduced by former 22. The strip 16 may be adhesively coated so that a seal is formed between overlapping edges thereof. Metal spacers of annular form and spaced apart or in the form of a helical rib formed on the inner tubular member are incorporated between the inner and outer tubular members.

Abstract: 994,120. Television. FERNSEH G.m.b.H. Sept. 27, 1963 [Sept. 28, 1962], No. 38143/63. Heading H4F. Apparatus for the regeneration of television signals containing a test line occurring within the standard vertical blanking interval comprises means controlled by horizontal and vertical blanking signals derived from the synchronizing signal contained in the television signal for producing in the regenerated signal a constant interference-free blanking signal, upon which is added a new synchronizing signal, likewise derived from the television signal, in which the derived vertical blanking signal is interrupted at least for the duration of the test line. The relationship between the white impulse in the test line and peak white in the picture signal is thus maintained since the test line is not blanked out. In the embodiment described the test line (Fig. 2b, not shown) is transmitted at the end of the vertical blanking interval (Fig. 2a, not shown) and the duration of the derived vertical blanking impulse (Fig. 2c, not shown) is made so that it terminates before the commencement of the test line. The television signal to be regenerated is received at 1 and fed to a device 2 in which alternating voltages superimposed upon the signal, such as hum voltages, are suppressed, control 20 of a clamp circuit serving for adjustment of the peak white level, and then to a device 3 in which it is blanked, control 30 serving for adjustment of the black level, and then to a device 4 in which the peak white level of the signal is limited at a potential determined by the setting of control 40 and finally to a device 5 in which a new synchronizing signal is added so that at the output 6 the complete regenerated television signal appears. The signal received at 1 is also applied to an amplitude filter 7 from which the horizontal and vertical frequency impulses are made separately available and in device 8 the required blanking signal components are developed and applied to device 3, and in device 9 new re-shaped synchronizing signals are formed and applied to device 5, their amplitudes being adjusted by control 90. So that the test line signal may be blanked out when it is severely distorted a switch 10 is provided, by means of which the whole of the vertical blanking interval including the test line may be blanked out and regenerated. The test line which comprises a peak-white impulse followed by a grey step-wedge may be used for monitoring purposes or for stabilizing the signal level.
