Abstract: 1,256,685. Automatic gain control. SONY CORP. 19 Feb., 1970 [22 Feb., 1969], No. 8059/70. Headings H3T and H4R. In an automatic gain control arrangement for a television camera 1, the output from the camera is fed to the base of transistor Q5 in gain controlling circuit 3 from the collector circuit of transistor Q4 an output being obtained which is amplified in amplifier 4. The output from amplifier 4 is fed to an output terminal and also to a clamp circuit 5 comprising transistor Q1, to the base of which a clamp signal synchronized with a horizontal synchronizing signal is applied. The clamping level is determined by a transistor Q2, the base bias of which is set by means of a potentiometer VR; diode D2 provides for temperature compensation. The output from clamp circuit 5 is rectified by a rectifying circuit 6, and may be applied by means of a switch S to a memory circuit comprising capacitor C2 and field-effect transistor Q3. The field-effect transistor Q3 is in common drain connection, the output from its source being applied to the base of transistor Q4 to control the gain of gain controlling circuit 3. It is stated in the Specification that the gain controlling circuit 3 may be replaced by a variable attenuator.

Abstract: 1,258,257. Conveyers. SIMON HANDLING ENGS. Ltd. 12 March, 1969 [14 March, 1968], No. 12403/68. Heading B8A. In a roller conveyer for load-carrying platens 5, a beam 14 for hauling the platens and a beam 16 for holding the platens stationary when they are not engaged by the hauling beam 14 are raised and lowered by a single draw bar 12. Each of a plurality of cross shafts 8 is connected to the draw bar by an arm 9, the shaft also carrying arms 10, 11 which have rollers for engaging the undersides of the beams 14, 16. To move the platens 5 along a roller track 3, the arms 10 are moved to the vertical position by longitudinal movement of the draw bar 12, the beam 14 being raised so that slots 18 of U-shaped members on the beam engage depending flanges of transverse platen bars 7. This movement of the bar 12 also causes the arms 11 to pivot downwardly and projections 19 of the holding beam 16 move out of engagement with the platens as the beam 16 is lowered. The hauling beam 14 is then moved longitudinally by a distance equal to the pitch between each adjacent pair of platens. The platens having been moved along the track, the draw bar 12 is then moved in the opposite direction, the hauling beam members 17 are disengaged from the platens, the holding beam projections 17 are raised and the hauling beam 14, still in its lowered position, is longitudinally moved to its original position with the U-shaped members 17 located beneath the platen bars 7.  Two such conveyers may be at an angle, normally a right angle, to one another, an intermediate section of roller track being alignable with the main tracks in turn. A conveyer may feed into the stream of a main conveyer by an intermediate section. In such a case, the holding beam may be replaced by automatically holding clamp means at each platen station in the feeding conveyer.

Abstract: 1,265,488. Sterilization of liquids. DRAYTON CASTLE Ltd. 1 July, 1969 [1 July, 1968], No. 31282/68. Heading A2D. In a process for the sterilization of liquids such as liquid for use in surgical work, wherein the liquid is sealed in a plastic container, the sterilization is carried out by placing the container and its contents in a pressure chamber, introducing steam rapidly to attain a predetermined steam pressure less than the pressure required to attain a temperature at which sterilization occurs, reducing and controlling the admission of steam to produce, during a period equal to the period which would be required to ensure sterilization if the pressure in the chamber had been the sterilisation pressure, a gradual rise in pressure to a value above the normal sterilising pressure. The steam may then be replaced by compressed air and the container sprayed with water to reduce its temperature.
