Title: Improvements relating to stereophonic sound apparatus
IPC: H04S1/00
Filed: 1960-01-18
Abstract: 939,218. Stereophonic transmission systems. TELEFUNKEN G.m.b.H. Jan. 18, 1960 [Jan. 17, 1959], No. 1714/60. Class 40 (4). In stereophonic sound apparatus including a first channel for transmitting a sound signal and a second channel for transmitting a directional signal indicative of the direction or position of the sources of the sound, a bridge having four resistive arms is connected between the channels and a signal fed to the sound channel is derived from or applied across a diagonal of the bridge while a signal fed to the directional channel is derived from a pair of oppositely disposed contacts which are movable together to make contact with points on respective opposite arms of the bridge. The outputs from a microphone MIM, Fig. 6, having a spherical polar response and from a microphone MIS of figure-of-eight characteristic are fed to amplifiers A 2 , A 1  respectively and to mixing controllers C 2 , C 1 . The microphones are set up for M/S stereophony. Sound signal from microphone MIM is applied across diagonal m, n of a resistive bridge R. Directional signal from microphone MIS is applied across diagonal o, p. A bridge output is obtained from two contacts 1, 2 which are infinitely variable or movable step-bystep to vary the proportions of the two microphone signals in channel S. Such movement of the contacts 1, 2 produces variation in the apparent position of the reproduced sound image obtained from two loud-speakers (not shown) fed respectively with sum and difference signals from channels M and S. A potentiometer B may be provided to vary the apparent width of the sound stage. Lateral inversion of the sound stage is obtained if the range of movement of the contacts 1, 2 covers 360 degrees. The potentiometer B may be replaced by a further resistive bridge, Fig. 7, not shown, the signal from microphone MIS being applied across one diagonal of the bridge and the output being taken from two movable contacts similar to those on the main bridge. Lateral inversion of the sound stage may then be obtained by adjustment of the movable contacts on the further resistive bridge. In an alternative arrangement, Fig. 10, two switches S 1  and S 2  are provided which, when positioned as shown, connect a bridge network R so that two closely situated cardioid microphones MIX and MIV arranged for XY stereophony provide a sound signal in channel M and a directional signal in channel S. When the switches are in the alternative position sound microphone MIM and directional signal microphone MIS, which replace the microphones MIX, MIY, provide a sound signal in channel M and a directional signal in channel S. A variable resistor B placed across diagonal terminals o, p of the bridge permits the width of the sound stage to be varied. An arrangement similar to that of Fig. 10 when set for X, Y stereophony but containing no switches S 1 , S 2  is described, Fig. 9 (not shown). Fig. 8 (not shown) shows an arrangement similar to that of Fig. 10 when set for M/S stereophony but containing no switches S 1 , S 2 .

Title: Improvements in or relating to apparatus for feeding material
IPC: F23K3/14
Filed: 1940-02-01
Abstract: 535,005. Step-by-step conveyers. STEVENS, A. H. (Morse Chain Co.) Feb. 1, 1940, No. 2015. [Class 78 (i)] In a conveyer suitable for feeding solid fuel to a heating stove A, Fig. 1, a conveying screw 13 advances with a non-rotating movement and rotates with an unthreading movement on the return stroke. The screw is actuated by pressure fluid acting alternately on opposite sides of a piston 17 and a pressurerelief valve 90 allows continued operation of the screw in the presence of an obstruction. The screw co-operates with a shearing lip 98 in the feed hopper D exerting against an obstruction a shearing action tending to sever the obstruction and a lateral thrust tending to move the obstruction gradually aside. As shown, the pressure fluid is supplied by a rotary pump 43, Fig. 2, on a shaft 49 driven through belt gearing 60, 61 from a motor 59. The pump draws oil from a sump 69 through a pipe 70 and expels it through a rotary valve 41 and passages 37, 40 alternatively to opposite sides of the piston 17. The valve 41 is rotated intermittently from the shaft 49 through worm gearing 52, 53, Fig. 3, and Geneva mechanism 56, 57. The rod 14 of the piston 17 is squared at 15 to engage a socket 16 on the screw 13 and is provided with a threaded portion 20 engaged by a collar 21. The latter rotates freely on the forward movement of the rod 14 and on the return movement is locked by clutch teeth 29, 30 to a fixed plate 31, causing a rotary unthreading movement of the screw through the fuel. The valve 90 for relieving pressure in the event of obstruction is provided on the duct 62 between the pump 43 and the valve 41, and may serve as a warning signal. The return movement of the piston 17 is terminated by the escape of fluid through a piston-controlled slot 75 in the cylinder 18, and the forward movement by the opening of ports 76 by an extension 80 of the piston rod. The ports 76 are formed in a sleeve 79 secured to an adjustment member 83 screwed on an extension 85 of the cylinder head and graduated to read against a fixed pointer 89. The shearing lip 98 in the hopper is formed on a separate section of tough material, such as a steel forging, detachable for grinding or replacement.
