Title: Improvements relating to apparatus for reducing the distortion of an electronic amplifier
IPC: H03F1/36
Filed: 1948-10-01
Abstract: 681,344. Valve amplifying circuits. VACKAR, J., and KLIKA, V. Oct. J, 1948, No. 25612/48. Class 40 (vi). An amplifier is provided with a voltage divider connected to the output terminals which supplies a voltage which in the absence of distortion would be equal in amplitude and phase to the input voltage, the difference of these two voltages, consisting of the distortion, being phase-inverted and added to the input. In this way the distortion is reduced without restricting the amplification. As shown, a voltage divider R<SP>1</SP>, R<SP>2</SP> is connected across the output of a resistance-coupled amplifier V<SP>1</SP>, V2, and arranged to provide a potential at point A<SP>1</SP>, differing only by an amount due to the distortion, from the potential at point A, the ratio R<SP>1</SP> + R<SP>2</SP> being equal to the total amplification, R<SP>2</SP> and the distortion is fed back to the grid through a phase-inverting transformer Tr, which may step up the voltage, or through an auxiliary valve, Fig. 5 (not shown). By this means distortion may also be reduced in a two-stage push-pull amplifier, Fig. 2 (not shown), a single stage push-pull amplifier, Fig. 3 (not shown), and a single stage amplifier, Fig. 4 (not shown). Specification 495,943 is referred to.

Filed: 1949-10-07
Abstract: 665,256. Moulding ceramic articles. RAM, Inc. Oct. 7, 1949 [July 14, 1949], No. 25773/49 Class 87(ii) A mould for ceramic ware comprises a pair of mould sections 10, 11 having opposed ware-forming surfaces 16, 15 shaped to define the body of the article, with the surface beyond the ware-forming surface in at least one section formed with a plurality of grooves 19 surrounding the ware-forming surface, with narrow aperture 21 connecting the grooves with each other and the innermost groove with the ware-forming cavity when the sections are in juxtaposed moulding position. When the mould sections are separated after the moulding operation the excess material, or flash, remains as part of the moulded article 23, since its material has also been compacted owing to the back pressure resulting from the constrictions between the gutters, and is attached to the article by a thin strip 33 forming a fracture line. Thus it is not necessary to remove the flash while the article is still in the mould. Surplus material 31 may still remain behind but the outer gutter 19 fills up during subsequent mouldings till the material in it is compressed and is eventually removed with the rest of the flash. Knife edges may be arranged to meet at the outside edges of the outermost gutter 19 to cut off any further excess material such as 31. The article may be eased off the mould surfaces by fluid (e.g. air) pressure exerted through porous mould bodies and applied by conduits 17, 18 embedded therein and positioned according to the contour of the moulding surface. The moisture content and density of the material, e.g. ware-forming clay, may be influenced by the shape and proportion of the gutters, several examples being given.
