Title: Improvements in or relating to Position Control Systems
Inventor: FRANKLIN DONALD PETER
IPC: G05B5/01
Filed: 1966-04-05
Abstract: 1,180,235. Mining machine control systems. ELECTRIC & MUSICAL INDUSTRIES Ltd. 20 April, 1967 [5 April, 1966], No. 15013/66. Heading E1F. [Also in Division G3] A system for controlling a device to follow a predetermined height profile comprises a height conscious means including a liquid-filled tube interconnecting a station at which the device is controlled with a datum station on a means for utilising the variation in hydrostatic pressure between the stations to control the position of the device in accordance with the profile. As shown, the portion of the control system to the left of the dotted line is carried on a coal cutting machine and comprises a tube 100, communicating with a tube 3 in a flexible water jacket 11, in which is a liquid column supporting a float 101 the position of which is sensed by a transducer 103 having an output controlling hydraulic valves 105 associated with the vertical motion actuators of the coal cutting machine. A freely collapsible diaphragm 102 prevents condensation of water vapour. To the right of the dotted line, at a fixed station, solenoids 108, 109 exert pressure on diaphragms 110 to position the liquid column. The pressure to be exerted by actuator 108 is predicted by a storage device 114, in dependence on the longitudinal position of the machine on line 117, and the actuator is energised through a digital to analogue convertor 115 in which a correction for the density of the liquid is effected in dependence on the temperature of the water-jacket 11 at point 116. The position of the solenoid 108 influences a position sensor 112 which controls an actuator 109 via an amplifier 113 to position a diaphragm 111 to bring diaphragm 110 to a desired position. Cooling water to the jacket is fed to an inlet 107 and from an exit 106. A chamber with a flexible diaphragm 118 is connected to pipe 3 and acts as a low pass filter to reduce high frequency surges along the pipe. In a modification the actuator 109 and diaphragm 111 are positioned adjacent to the tube 100 on the machine to speed up the forward response of the control system. The air spaces above the diaphragms 102, 110 and 111 are connected by a tube 10 passing through the water jacket 11. The predetermined profile is held in the storage device 114 and after several traverses the coal face is inspected to check the profile and errors are recorded and introduced into the storage device so that for subsequent traverses it can entrapulate a more accurate profile.

Filed: 1948-06-04
Abstract: 642,819. Rotary brushes. COLLARO, C. June 4, 1948, No. 15201. [Class 19] A rotary brush is formed of strips of rubber or like flexible material clamped between the flanges of three or more anglesection strips of rigid material, the rigid strips being secured together to constitute a rotatably mounted supporting member for the brush. The rigid strips may be made of plastic material but are preferably made of metal. The flexible strips may be arranged parallel to the axis of the brush or helically around it. In Figs. 1 and 3 four curved rigid strips 10 of rightangle cross-section are arranged so that when placed together the flanges are helically disposed about the rotational axis and receive the two flexible strips 11. The rigid strips are secured by rivets, or other fastening members 12, which pass through holes in adjacent flanges. The longitudinal edges 13 of the rigid strips 10 are flared away from the flexible strips and adjacent portions of these flanges may be bent or grooved slightly at 14 to grip the flexible strips more firmly. The ends of the rigid strips 10 extend slightly beyond the flexible strips 11 and they are cut away as 'shown at 15 so as to provide a recess bounded by shoulders 16 to receive the end of a driving spindle which is provided with one or more projections. The extreme ends of the flanges of the rigid strips may be bent towards the corresponding ends of adjacent strips. Fig. 4 shows an alternative arrangement of the flexible strips in which four separate flexible strips 30 are clamped between the parallel flanges of adjacent strips 10. If desired, any number of flexible strips may be used and the angular section of the rigid strips should be modified accordingly. The rigid strips may have longitudinal and/or transverse ridges or grooves to retain the flexible strips more securely.

Title: High-frequency aerial
IPC: H01Q1/12
Filed: 1958-05-13
Abstract: 842,060. Aerials. ASSEM VAN DEN, C. F. P. May 13, 1958 [May 20, 1957], No. 15317/58. Class 40(7). In order to prevent or minimize wind vibrations in rod aerial elements they are mounted on a support by securing means of plastic material having a substantialinternal mechanical hysteresis. The securing means consists of a sleeve 4 fitting over the central portion of the aerial element 1 and a socket 5 for the support 3. Extending between the two are a pair of extensive flanges 6 and, at right-angles, a pair of less extensive flanges 7. The securing means thus imparts a substantial measure of rigidity to the element in one plane containing the element axis and a lesser degree of rigidity in another such plane at right-angles to the first. This, coupled with the damping effect due to the material used, is stated to have the desired effect. The securing means is preferably of integral construction formed in polyethylene by injection moulding. The sleeve 4 is interrupted along its length as indicated at 8 and it is preferred to use a square-section support 3 and to attach the securing means to it by a screw 9. Dipoles, folded dipoles, and/or parasitic elements may be secured to a common support by using an appropriate number of the securing means described. The socket portions 5 of the outermost ones should be closed at their outer ends and, if the aerial elements are tubular, these should also be closed as indicated at 2 to prevent organ-pipe effects.

Abstract: 748.903. Turbine and compressor blades. POWER JETS (RESEARCH & DEVELOPMENT), Ltd. May 21, 1954 [June 4, 1953], No. 15406/53. Class 110(3) A blade for a compressor or turbine comprises a tubular working portion of aerofoil cross-section, the root ends of the faces of the tubular portion being formed into loops which fit closely around wires extending transversely to the blade axis. The loops and wires are wedge-shaped in cross-section with the apices of the wedges pointing towards the tip end of the blade, and the loops are engaged in spaced undercut grooves in a root block. In Figs. 1, 3 and 4, the blade is formed either from tubular stock or from sheet metal folded about the leading edge. and the extensions of the concave and convex surfaces are flattened at 1a and folded around two wedge-shaped wires 2 to form loops 1b. The two dovetail portions thus formed are entered in corresponding slots formed in a root block 3 which also has grooves 3a in its side faces for engagement with the inturned flanges 4a, 5a of the rotor discs 4, 5. The flanges 4a, 5a are stiffened by rings 6, 7 and the two rotor discs are connected by screwed rings 8, 9 welded to the discs as described in Specification 728,754. The root block is shaped to give the blade the desired stagger angle. In a second embodiment, a single groove is formed in the root block and a spacer is disposed in the groove so as to form two spaced grooves for the wedge-shaped loops on the blade faces. In another embodiment, the blade is similar to that shown in Figs. 1, 3 and 4, but the loops are symmetrically formed about radial planes. in Fig. 7, the wedge-shaped portions are curved instead of straight as in Figs. 1, 3 and 4 so that the platform portions 1d are reduced or eliminated. In Fig. 10, the wedge-shaped portions are curved to correspond with the curvature of the concave and convex aerofoil surfaces, the blade platforms being entirely eliminated; in this embodiment, the root block 14 is cast on.

Title: Improved image development
IPC: G03G15/08
Filed: 1960-05-03
Abstract: 952,609. Printing processes. RANK-XEROX Ltd. May 3, 1960 [May 7, 1959], No. 15524/60. Heading B6C. A method of producing a powder image on an insulating transfer surface comprises forming a substantially uniform layer of charged conductive particles on the surface of a layer of photoconductive material supported on a conductive base, exposing the photoconductive layer to a pattern of activating energy to selectively vary the conductivity through the photoconductive layer, and placing the transfer surface in contact with the powder layer with an electrostatic bias applied behind and across the transfer surface to effect selective transfer from the powder layer to form an image on the transfer surface. The photoconductive layer may be sprayed with powder particles less than 20 microns in diameter in aerosol form. Charging may be by a corona discharge electrode mounted on a sleeve which traverses a screw drive shaft. Exposure may be to light through a transparent conductive backing, or to X-rays or other radiation through a backing which need not be transparent, or through the particle layer. Image transfer may take place during or after exposure, by bringing against the particle layer a transfer member comprising an insulating layer with a charged conductive backing, or by rolling a transfer sheet against the particle layer by means of a charged or grounded roller. The transfer member may be polyethylene, or polyethylene-coated paper. In one form, the photoconductive layer 131 is supported on half the periphery of a rotatable drum 130. Powder is applied to the layer 131 by a brush 62 controlled by a cam to contact the drum when the layer 131 is passing. The powder layer is charged at a station 54. An original 142 is fed against the drum 130, where the layer 131 is not present, by a cam-controlled roller 136, and light from fluorescent tubes 133 is reflected from the original on to the back of the layer 131, which at the same time as the exposure, passes a transfer station 144, where a transfer sheet or web 147 is fed against the layer 131 by a camcontrolled, conductive and electrostatically biased roller 145 having a conductive layer 146 of sponge rubber. The image is fixed at a station 64. The remaining charge is removed by a fluorescent tube 58. By controlling the potential applied across the transfer zone, either the powder on that part of the photoconductive layer which has been exposed to radiation, or the powder on the unexposed part, can be transferred.
