Abstract: 1,166,908. Measuring propagation loss. J. B. HAMILON. 3 Aug., 1967 [28 Sept., 1966], No. 35771/67. Heading H4L. In a system for measuring the propagation loss when surveying for the location of microwave radio stations, a pair of airborne platforms, e.g. tethered helicopters, are used to carry transmitting and receiving equipment whereby line-of-sight communication may be established between the helicopters and the received signal strength measured over a range of heights. As shown in Fig. 2, helicopters 10, 11 are situated at sites X, Y and stabilized in altitude by cables 12, 15 and windlasses 13, 16, respectively, the windlasses being controlled from the helicopters via electric cables 14, 17, respectively. A device 30 on the windlasses records the length of tether cable as it is played out or drawn in to the windlass. Microwave aerials 18, 19 are carried by the helicopters and are stabilized in roll and pitch by stabilizers 22, 23, respectively. The line-of-sight communication is established by radar tracking devices 20, 21 which control the orientation of aerials 18, 19, respectively.

Abstract: 1,152,835. Semi - conductor transducers. WESTERN ELECTRIC CO. Inc. 23 June, 1966 [28 June, 1965], No. 28136/66. Heading H4J. [Also in Division H1] An electromechanical transducer comprises a semi-conductor crystal 10 having a dielectric constant at the device operating temperature in the range 100-1000, provided with electrodes 11, 12, and containing a rectifying barrier between one electrode 11 and the body 10. Pressure transmission means, e.g. a stylus 13 pressing on the electrode 11, are provided to apply pressure changes to the crystal and thereby to vary the impedance across the rectifying barrier, or to receive pressure changes from the crystal. The preferred form comprises a ferro-electric crystal 10 of the perovskite class, e.g. KTaO 3  or KTa x  Nb 1-x O 3 , having a rectifying gold or platinum electrode 11 vacuum deposited on a freshly cleaned surface thereof, and an ohmic electrode 12 provided by vapour deposition of, e.g. chromium, aluminium or titanium. A gold film overlay may be formed on the electrode 12. Preferred crystal conductivity and dimensions and electrode thickness are given. Such a device may be included in the microphone of a telephone receiver, in which case the stylus is connected to a pressure-sensitive diaphragm. The crystal may either be mounted on a second diaphragm within the microphone to minimize the risk of damage by shock, or may be mounted on a metal cantilever support (21), Fig. 2 (not shown), insulated from the casing (23) by a block (22). A screw (26) urges the support (21) upwardly to provide a preset pressure bias between the stylus (25) and the crystal. The device may alternatively operate within a loud-speaker, variations of voltage across the rectifying barrier leading to pressure changes which may be transmitted to a diaphragm through a stylus.

Inventor: ROSSI P
IPC: B21D11/12
Filed: 1982-11-17
Abstract: In order to allow an adjusting of the bending tools to a given diameter of the wire being bent allowing the producing of the requisite bending radius a central mandrel which forms two bending or forming, respectively, jaws is replaceable together with a shearing tool. To this end a hollow shaft is mounted at the rear of the central mandrel, which shaft is mounted to a supporting shaft by means of a screw joint. The supporting shaft is supported in turn rotationally and can be rotated by means of a motor in order to disconnect the central mandrel. By mentioned rotation the screw joint is released. A special coupling of the shearing tool to an axially movable operating shaft allows a simultaneous disconnecting of the shearing tool together with the central mandrel. A bending mandrel is mountable at locations having various radial distances from the central mandrel. A cover plate provided with a position control element operates together with proximity switches such that two defined initial angular positions of the bending mandrel is maintained independently from mentioned adjustments.

Title: Potato processing apparatus
Inventor: WRIGHT RAYMOND GRENVILLE WHITE
IPC: B26D3/26
Filed: 1982-06-01
Abstract: A walking beam conveyor 28 feeds potatoes in a direction F to a cutting station where they are cut along planes 41 and 42 into four pieces. The conveyor 28 is pocketed and the pockets are configurated so that they cause each potato on the one hand to become oriented with its larger dimension generally at right-angles to the feeding direction F, and on the other hand to move to a central position transversely of the conveyor 28. Thus, each potato is in a predetermined position when it arrives at the cutting station, so that the four pieces into which it is cut are roughly of equal size.

Title: Method and apparatus for monitoring and controlling the filling of receptacles with a determined weight of material
Inventor: GRAFFIN ANDRE JEAN-JACQUES
IPC: G01G17/06
Filed: 1984-11-13
Abstract: A rotary carrousel of a filling installation includes a plurality of filling stations each equipped with a volumetric dispenser (37) whose volume may be varied by varying its dispensing time or the stroke of a piston in a cylinder. At least one of the filling stations includes a balance (36). As a receptacle (39) passes through the filling installation in a filling station equipped with a balance, it is first weighed empty while the corresponding dispenser (37) is filled, and it is then weighed continuously as the material is transferred from the dispenser to the receptacle. The actual weight of material dispensed is determined by comparing the full and empty weights of the receptacle. This weight is compared with a set weight. Any drift which is detected from the set weight can be corrected for subsequent receptacles passing through the filling installation by varying the volume of the material dispensed.

Title: Phosphine fumigation method and apparatus
Inventor: WINKS ROBERT GORDON
IPC: A23B9/18
Filed: 1990-06-26
Abstract: Fumigation of grain in a storage facility having a plurality of grain silos (13) is effected from a single source (10) of a mixture of a carrier gas and a gaseous fumigant. The single source is connected to a single gas supply duct (11), to which gas inlet ports (16) of the silos are also connected. The connection between each gas inlet port and the duct is provided with a respective valve (14) and a respective orifice plate (15), which is adjusted so that the pressure drop across the orifice plate into the silo is substantially greater than the pressure drop across any other component between the gas source and the silo. With this arrangement, the flow rate of gaseous fumigant through the grain-containing silos in the facility suffers only a minor perturbation when a valve between the gas supply duct and a silo is opened or closed. This minor perturbation can be readily compensated by returning the gas pressure in the duct to its previous value. <IMAGE>
