Title: Filter device
IPC: B01D29/09
Filed: 1969-11-28
Abstract: 1282427 Moving band filter and operation thereof MASCHINENFABRIK SACK GmbH 28 Nov 1969 [10 Dec 1968] 58330/69 Heading B1D Each successive section of a non-endless band 12 of nettle cloth is used for a plurality of successive filtering operations, during which liquid passes through the band from inlet chamber 8 to outlet chamber 7, a used section being withdrawn from between the chambers after filtering, cleaned by means 34 and returned to the chambers for re-use. Only after a section is worn out is it allowed to remain out of the chambers to enable the following section to be used for filtering. Cleaning means 34 comprises a scraper, rotary brush and compressed air nozzle acting successively on the band. Doors 26, 27 clamp the filter band which is supported by a grid 11 during filtering. Liquid is delivered by distributor 22 .. 25 until a band section clogs, then liquid supply is shut off and compressed air delivered to force remaining liquid through the band and dry the cake. The doors are raised and the band moved by reversible drive motor 21 and returned by motor 20. These motors may be air motors or involve slipping clutches. In Figs. 1, 3 (not shown) band 12 is carried across grid 11 by an intermediate support belt, which may be endless or non-endless and has drive motors separate from those driving band 12.

Title: Hydraulic work positioning saddle
IPC: B23K37/053
Filed: 1970-12-14
Abstract: 1311309 Work positioning saddle COMBUSTION ENG Inc 14 Dec 1970 [19 Dec 1969 59241/70 Heading B3B  An hydraulic work positioning saddle 12 comprises a base frame 24, a ram 62 slidably mounted on a fixed piston 54, Fig. 6, the piston and ram defining a chamber 84, and a wedge 110 which co-operates with a ring 112 so that movement of the wedge and consequent movement of the ring controls the flow of fluid to chamber 84 and thus the movement of ram 62 upwardly or downwardly. The 'edge is driven by reversible electric motor 108 via a lead screw 124 and a captive nut 122. As shown in Fig. 2 saddles can be arranged in pairs with tie bars 26 adjustably connecting them together. Fig. 1 shows four saddles used to support and position a vessel 10. Each saddle has switch means associated with the wedge and the ram so that movement of the rams can be stopped when the limit of movement of the parts is reached. Also the switch means can denote through electrical circuitry the direction of movement of the ram and whether it is above or below a median position. Apparatus controls are associated with a console 16 and a pendant 18. Vessel 10 has spiders 20 containing cross hairs positioned therein. An operator has an optical alignment instrument 22 which is in alignment with a reference point with which it is desired to align the vessel axis. The required direction of movement of each jack for alignment in say the horizontal plane is determined by the operator and set as such on the console 16. Operation of a forward drive button on the pendant produces the necessary movement of the rams and when the vessel axis is suitably aligned the button is released. If the rams are moved too far a reverse button can be used to reverse the movement of the rams. When the vessel is correctly aligned the rams are let down so that they rest on ring 112 and wedge 110. This downward movement is slight and is not sufficient to affect the vessels alignment. For maintenance operations each ram can be moved upwardly without operation of the wedge.

Title: Direction finding system
IPC: G01S3/32
Filed: 1978-10-20
Abstract: An antenna array for direction determination comprises two pairs of elongated end-firing log-periodic antenna elements 1, 2 and 3, 4, each pair fixed symmetrically to a reference plane 5 and forwardly convergent to it. The two antenna elements of one pair converge forwardly at an angle b, those of the other pair converge at an angle a = 1.5 b. From the detected and amplified signals of each pair there is obtained a difference signal designated L1, for the b-angle pair, L2 for the a-angle pair. A third difference signal L3 is obtained from L2-L1. The magnitude of each difference signal depends upon value of an angle V between a boresight axis 12 and a detected radiation source. An indication of V is taken on the basis of L1 if L1, L2 and L3 are on the same side of zero. A more precise indication of V is then taken on the basis of L2 by comparing absolute value of L2 with the absolute value of an adjustable reference signal. <IMAGE>

Title: Improvements in Electromagnetic Induction Systems for Geophysical Exploration and Conductor Location
IPC: G01V3/10
Filed: 1979-11-29
Abstract: Ground effects in pulse induction metal detectors are eliminated by comparing the actual response with a simulated response of the ground. The gated, amplified and synchronously detected voltage D at the output terminals of a receiver coil due to a pulsed primary magnetic field A produced by a transmit coil is fed to one input of a differential amplifier to the other input of which is applied the simulated signal and which is derived from an RC ground effect eliminator (Fig. 3) which fits a predetermined functional form E to the receiver coil output, which form corresponds to that due to background magnetic material. Any output signal F from the differential amplifier indicates a metal. The transmit and receiver coils are constructed to minimise coupling therebetween due to magnetic viscosity effects and the receiver coils form a gradiometer to reduce noise levels. The simulator may use exponential functions or reciprocal of one varying linearly with time. <IMAGE>
