Title: Method of distorting electrical vibrations and means for carrying the method into effect
Inventor: BIERL RICHARD
IPC: G10H5/02
Filed: 1953-02-20
Abstract: 745,436. Changing wave-shape. HOHNER AKT.-GES., M. Feb. 20, 1953 [Feb. 29, 1952; July 7, 1952], No. 4819/53. Class 38 (2). [Also in Groups XXXVIII andXL (c)] Waveform distortion is produced by means of a voltage divider comprising two or more non - linear impedance elements of different characteristics, one of which may comprise an over-driven thermionic amplifier. The invention is primarily for use in electronic musical instruments. Oscillations are applied to a pair of pentodes 3, 4, Fig. 1, in push-pull, which distort the waveform to a degree controllable by variation both of the grid and screen potentials, via leads 5, 6 respectively. The valves feed over transformer 8 into a network 9 which includes non-linear resistance elements and produces the major part of the distortion. The secondary 10 of the transformer 8 is centretapped and the network 9 includes symmetrically-connected rectifiers 12, 14 producing symmetrical distortion and also unbalancing arms 17, 18 and a diagonal branch 23 whereby asymmetrical distortion may be produced. The output terminals 26, 27 may be connected across the whole or one side only of the network, by means of switch 29, while switches 32, 33 may be used to vary the portion of the transformer primary connected in the anode circuits of the valves 3, 4. When assymetric distortion is required the valve 4 may be disconnected by means of switch 44a. Transient effects may be produced by means of a switch 39 which connects resistance-capacity networks 41, 42, 43 in the common anode circuit, while the waveform may be modulated by variation of the anode potential applied to the valves. The frequency-range over which distortion is produced is varied by means of a variable condenser 44 connected across the transformer primary. Distorting networks including non-linear resistance elements may also be connected in the grid circuits of the valves 3, 4 (Fig. 2, not shown), together with switchable resistance-capacity networks determining the frequency range. The grid bias may be derived from a potentiometer including pressure-sensitive resistors connected, with the keyboard of an electronic musical instrument. Alternative distorting networks for connection in the anode circuits of the valves are also described (Figs. 2, 3, not shown), and include the use of a transformer with two secondary windings, one of which is wound on a core movable relative to the main part of the transformer core. Alternative non-linear resistance elements comprise glow-lamps, barretter tubes or saturated core chokes. The distorting networks may be followed by a further circuit comprising a series resistor 96, Fig. 4, and shunt potentiometer 95, the latter being ganged with a variable condenser 97 shunting the resistor 96.

Title: Improvements in brick moulding machines
IPC: B28B7/24
Filed: 1924-03-01
Abstract: 224,778. Wismar, L. C. March 1, 1924. Moulds.-Relates to brick-moulding machines of the kind in which the bricks are formed in a mould box having longitudinal and transverse partitions 13, 1 respectively and are ejected from said box by means of plungers 7. The longitudinal partitions 13 are connected to a rockshaft 12, by means of which they can be lifted out of the filled mould box before the ejection of the bricks, each partition being accompanied by a forked stripper 16, which is pivoted to a separate shaft 14 and linked to the partition so as to swing with the latter into an upright position after the partition has left the mould. The strippers are provided with rearwardly prolonged lever arms 15 interconnected by a rod 18, which is connected by a link 19 to a lever arm 20, 22 secured to the shaft 12, while the plungers 7 are secured to a plate 44 guided vertically by a rod 45. The shaft 12 is coupled to an operating lever 9, mounted on a shaft 8, by rods 10, 11, so that, when the lever 9 is moved to the left, the partitions 13 are lifted through the strippers 16 out of the mould. At approximately the same time, a tappet 36 on the shaft 8 operates a crank 31 to release the strippers, which are held thereby, and when the lever arm 20 contacts with a screw 23 on the arm 22, the latter will be operated to raise the strippers. As the movement is continued, the plungers 4 are raised through a slotted arm 6, secured to the shaft 8, and a link 5 connected to the rod 45 to free the boards 2 and bricks 43 out of the mould box. The shaft 8 is also provided with an arm 37 having a latch bar 38, pivoted thereto, sliding in a slotted plate 39 and engaging the latter by either of two notches 40, 41 so as to lock the machine in two different positions, namely, when the plungers 7 are at their highest level, and when they have sunk sufficiently below the top of the mould box to allow the boards 2 to be replaced. The lever 9 is then moved to the right, when the elements, with the exception of the strippers 16 which are retained by a catch 25, are restored to their initial position, after which the mould is refilled. The catch 25 is then released by a hand lever 28.

H., of General Electric Co., Wembley, Middlesex. Feb. 23,1931, No. 5634. [Class 40 (ii).] An optical projection system for reproducing sound from talking films, for electrical picture transmission, &c., without the aid of a slit and permitting most of the apparatus to be arranged on one side of the film comprises means whereby light from a source is deflected by an inclined sharp-edged deflector through a lens and the film, a mirror behind and adjacent the film reflecting an image of the deflector through the lens to form another image whose central portion is cut off by the deflector. The parts of this image produced by the rays passing the sharp edge of the deflector fall on a light sensitive cell. As shown, light from a source 1 is directed by lens 2 on a deflector 3 with sharp edge 4, and the rays are deflected through lens 5 and record film 9 on to a mirror 7 which forms an image 61 of the deflector. Rays from this image pass through the lens 5 to form an image 3<1> which is largely cut off by the deflector and acts on the cell 8.
