Title: Means for forming sound holograms
IPC: G03H5/00
Filed: 1970-01-14
Abstract: 1,260,454. Acoustic holography. COMPAGNIE GENERALE D'ELECTRICITE. 14 Jan., 1970 [15 Jan., 1969],No. 1921/70. Heading H4D. A system for forming an acoustic hologram of an object 4 comprises a sound source 2 providing an illuminating beam, a two-dimensional matrix of transducers T1-TN receiving reflected sound from the object, and addition circuits A1-AN each receiving on one of its inputs the output signal of a respective transducer and on its other input a reference signal having at any instant a value proportional to a mean value (derived at 6) of the output signals of the transducers T1- TN. The outputs of the addition circuits constitute the hologram, which can be optically recorded by modulating lamps L1-LN (e.g. light-emitting diodes) with these outputs, and conducting the light to photographic plate 8 by optical fibres F1-FN. By synthesizing the reference signal as above, good holograms can be formed even if object 4 is remote and if variations in characteristics of the intervening medium (e.g. sound speed variations in sea water) introduce disturbing phase variations. A reference beam incident obliquely on the transducer matrix from the direction of object 4 may be simulated by applying differential delays to the inputs of mean-deriving unit 6 and/or to the reference signal inputs of addition circuits A1- AN, these delays being a function of the relative positions of transducers T1-TN.

Title: Magnetic aplifier apparatus
IPC: G05B11/01
Filed: 1962-01-23
Abstract: 998,382. Automatic control. ROBERT SHAW CONTROLS CO. Jan. 23, 1962 [Jan. 27, 1961], No. 2488/62. Heading G3R. [Also in Division H3] An automatic control system includes a magnetic amplifier, Fig. 1, in which a first saturable reactor SR1 is connected in series with a halfwave rectifier 10 and a load 12 to an A.C. supply 14, a variable impedance element 16 is connected in parallel with the rectifier, and a second saturable reactor SR2 is connected across the series combination of the first reactor and the rectifier, the load current being determined by the setting of the element 16. The rectifier is effectively short circuited when element 16 has zero impedance and the supply voltage is absorbed in fully switching both reactors during each half cycle. Minimum current then passes through the load. On the other hand when element 16 has maximum impedance, reactor SR1 is maintained in one saturation state only by the unidirectional rectifier current and the reactor SR2 remains in the other saturation state due to the passage of unidirectional current in the half waves when the rectifier is non-conducting. Maximum current then flows through the load. Intermediate load current values are obtained for settings of element 16 between the limiting values. An application is described, Fig.2, in which the load consists of a light source 20 which is maintained at a constant level by a photocell detector 18, the photo-cell having a negative impedance V illumination characteristic and functioning as the variable element 16. The circuit may be used to provide a constant current or voltage which is adjusted by varying the distance between the light source and the photo-cell, by introducing a shutter, or by using an auxiliary light source. A further application, Fig. 3, controls the heating by resistor 22 of a closure 24 so as to provide a constant temperature. As shown, the variable impedance element comprises a capacitor 26 and variable inductor 28, the two elements being tuned to series resonance for a selected minimum setting of the gap between inductor core portions 32 and 34. The gap is preset by a control knob 44 and is varied by the action of a bellows 38 which is in fluid connection with a hydraulic sensing bulb 36, the gap being reduced as the temperature rises. A general modification, Fig. 4 (not shown) is to couple the variable impedance element by a transformer to the rectifier 10, a condenser being connected in the primary circuit to block D C. currents.

Title: Improvements in rotating corn cleaners
IPC: B02B1/02
Filed: 1962-01-24
Abstract: 978,219. Grain cleaners. N. ANDERSSON. Jan. 24, 1962, No. 2586/62. Heading A2Q. In apparatus for cleaning grain falling through an upwardly moving, winnowing current of air within a cylindrical drum 1, the falling grain is spread to form a hollow cylindrical layer, within which is located a turbine wheel 10 having blades 14, so shaped and set that a portion of the upwardly moving air passes through and rotates the wheel and is deflected, by its blades, towards and through the cylindrical layer of falling grain. The drum 1 has an upper tangential outlet 2, connected to an exhauster or like suction device, and a lower opening 3 admitting air and serving as an outlet for cleaned grain, which falls, through a gap 20, into a receiver 4. Within the drum is a cylindrical part 18 spaced from the drum wall by a relatively narrow, annular passage 19 leading to the outlet 2. Grain is fed into the drum through a central tube 5 terminating in a discharge opening 6 located above a frusto-conical grainspreading plate 7 carried on a cylindrical tube 16 secured to the turbine wheel around its shaft 8, which is supported by a cross-piece 9. Alternatively, the plate 7 may be secured to the top of the shaft 8. The blades 14 are preferably surrounded by a frusto-conical ring 15 secured to the turbine wheel, as by arms 17 on the tube 16. The ring 15 is spaced from the plate 7 by a gap 21. The plate 7 prevents grain from falling into the turbine wheel and, together with the ring 15, gives the falling stream of grain the form of a hollow cylindrical layer. Chaff and dust are carried, in the current of air, through the passage 19 and the outlet 2.
