Title: Improvements in or relating to a method of accelerating the drying of coated surfaces
IPC: B05D3/02
Filed: 1948-05-18
Abstract: The drying of a surface, e.g. of paper, fabrics, film or metal foil, coated with a composition comprising a liquid vehicle is accelerated by applying a substance, liquid at ordinary temperatures which admixes on the surface with the liquid vehicle to form a mixture having a substantially lower boiling point.  In a modification the substance may be applied prior to coating.  In examples, compositions having toluene or butyl alcohol as vehicles have ethyl alcohol or water added.  During drying the solvent may be recovered by condensation and the residual air recirculated. Additional tinting materials may be included in the added solvent which may be applied to part of the coating only.

A line of text stored in the computer is in the form of a digital series of 16-bit binary words, the first two bits indicating white state or black state (for text), illustration state, or end of line, while the last fourteen bits indicate the duration of the indicated state. The words are sent to an electronic logic circuitry 82, which controls the modulation of a laser beam 84 which scans a photosensitive write drum 20 while a second laser beam 38 scans the drum 18 synchronously, the two lasers being stepped for line-spacing on receipt of an end-of-line signal by a stepping motor 56. For each line, four words are fed to the circuitry 82, the fourteen duration bits of each word being shifted into four respective down counters, counted down by a clock oscillator which also clocks the state of the words into two shift registers. The outputs of the registers respectively control the flow of information from the illustrative copy scanning device and the black and white of text matter. In this way, a complete page is recorded on the drum 20, with the text and illustrative matter in the correct positions.

Title: Improvements in or relating to separation of iron ores
IPC: B03D1/02
Filed: 1944-07-20
Abstract: In a pretreatment method for concentrating iron ores the pulp of a size suitable for froth flotation is subjected to two conditioning operations, the first with an anionic promoter of the fatty acid type, and the second with a sufficient amount of an alkaline earth metal oxide to convert the anionic reagent to an insoluble soap and produce an alkaline pH, the conditioned pulp being then subjected to a froth flotation process.  The ore is ground if necessary, and conditioned with an anionic promoter, e.g., a fatty acid, and then with the oxide of an alkaline earth metal, preferably in its hydrated form, e.g. lime which also has a depressant effect on the iron.  The pulp is then subjected to froth flotation, a frother may be added, and the silica floated off.  The iron concentrate is then cleaned and deslimed and treated by a further separation process which may comprise a further anionic conditioning and flotation or a gravity concentration.  A final iron concentrate suitable for blast furnace feed is obtained.  Specification 612,107 is referred to.  The Specification as open to inspection under Sect. 91 shows the flow sheet as including a final cationic flotation.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements in and relating to synchronising systems for oscillators
IPC: H04N5/12
Filed: 1950-06-06
Abstract: 677,481. Valve generating circuits. BRITISH THOMSON-HOUSTON CO., Ltd. June 6, 1950 [June 10, 1949], No. 14114/50. Class 40 (vi). An oscillator which has a tuned circuit is synchronized by means of synchronizing pulses which are applied so that energy is absorbed from the tuned circuit during a predetermined portion of the oscillatory cycle and the absorption of energy is discontinued during the occurrence of the synchronizing pulses. Fig. 1 shows such a synchronized oscillator used as a line scanning oscillator in a television receiver. Incoming television signals at aerial 1 are applied to a first detector and oscillator 2; I.F. amplifier 3; second detector 4 and video amplifier 5, the output signals from which are applied to the modulating grid of a cathoderay tube 6. The signals from the second detector 4 are also applied to a synchronizing signal separator stage 8 the frame frequency synchronizing signals from which are used to control the frame scanning circuit 7. Negativegoing line synchronizing signals from stage 8 are applied to a normally conducting valve 15 in the anode circuit of which is a resonant circuit 18, 19 which is tuned to approximately the line synchronizing signal repetition frequency. Valve 22 with tuned circuit 18, 19 operates as a Hartley type oscillator, capacitor 20 acquiring a charge so that valve 22 is held non-conductive except during a small portion of the oscillatory cycle. Capacitor 29 which charges from battery 28 through resistors 27 and 30 is periodically discharged by the pulses of anode current in valve 22 so that a voltage as shown in Fig. 2c is produced at anode 26 and is applied via capacitor 31 to the line scanning coils 12 via the amplifier and E.H.T. flyback generator 10. Valve 15 conducts only during the positive half cycles of the sinusoidal voltage produced across the resonant circuit 18, 19 when it absorbs energy from the tuned circuit, during the synchronizing pulses valve 15 is non-conductive and has no damping effect on circuit 18, 19 so that energy is induced into the tuned circuit at the frequency of the synchronizing signals. Noise and other unwanted pulses thus have little effect on the scanning frequency of the oscillator. In a modification, Fig. 3 (not shown), the anode of the valve to which the synchronizing signals are applied has a potential applied to it from a battery but is such that the valve is rendered non-conductive during the negative swings of the sinusoidal voltage across its tuned anode circuit. A pentagrid valve is used as the Hartley-type oscillator and the wave-shaping network is included in the anode circuit and thus does interact with the oscillator section of the valve. In a further modification, Fig. 4 (not shown), the capacitor of the tuned circuit is connected across the lower portion of the inductor. Increased excitation of the oscillator may be obtained by the use of a bi-filar wound inductor in the resonant circuit which is tuned by its own self capacity, Fig. 5 (not shown). Specification 677,478 is referred to.
