Title: Wall Contacting Tool
IPC: E21B17/10
Filed: 1978-12-08
Abstract: A wall contacting tool, such as a fixed blade rotating stabilizer, useful in earth boring has replaceable wear pads 23. Each pad 23 is of generally sector shape cross section, the pad corner having a 90 DEG  apex angle and fitting in a correlative V groove flute 39 at the end of an arm of the stabilizer body, being held in place by radial dowel pins 47 each bisecting the apex angle of the corner and flute. Each pin 47 has a head 49, 51 turned to be retained in a slot 57, 59 in the body and having a threaded socket receiving a cap screw 25 whose head engages an outwardly facing shoulder in a stepped hole in the pad. The pad corner above and below the dowel pin locks the dowel pin head against turning. A releasable retainer ring 75 in an annular groove 77 in the stepped hole prevents withdrawal of the cap screw 25 from the pad 23. A lateral dowel 83 inbetween one side of the pad corner and one side of the body flute prevents movement of the pad radially outwardly from the flute. <IMAGE>

Patent GB-2023501-A (GB)
Title: Electrostatic colour printing method and apparatus
IPC: G03F3/08
Filed: 1979-06-21
Abstract: The apparatus has multiple independent stations each having a master sleeve with an image in semipermanent fixed primary dielectric toner formed thereon. The image is transferred directly or by way of an intermediate transfer roll. The master sleeve is charged in light, the toned parts retaining charge. The resulting now charged image is toned with a pigmented secondary toner and this double toned image is pressed against the passing substrate or brough very close to it either directly or through the transfer medium. An electrical field is established between the substrate and the sleeve or transfer medium, the toner transferred to the substrate and the sleeve or transfer medium circulate back to pass through the same process of charge, tone and transfer. The transferred images are fixed between or during movement through the stations. Image density information can be used to control change in the electrical field conditions or other parameters. The impressions from each station are applied in registration.

Title: Removing Surface Fibres from Animals
IPC: B26B19/24
Filed: 1979-10-08
Abstract: Surface fibres are removed from live animals, carcasses or hides, and particularly wool is removed from sheep, by a broad fibre impacting member 9 having a plurality of spaced shallow indentations which is rotated so as to strike successive groups of fibres in a direction transverse to the direction of the fibres. The fibre impacting members 9, are connected to rotating blades 1 and 2 which are rotatably driven within a housing 8 having a wool intake opening 12 and a fibre and air discharge opening 13.

Patent GB-2107540-A (GB)
Title: Feedforward amplifiers
Inventor: GERARD ROGER EDWIN JOHN
IPC: H03F1/32
Filed: 1981-10-14
Abstract: In a feedforward amplifier distortion signals are inevitably introduced to a greater or lesser extent, and the layout of a feedforward amplifier is such that at certain points 21; 32, there is ideally only a power input signal or its amplified replica, whilst at other points 22; 31, there is ideally only the distortion signal present, and no signal which corresponds to the input which is to be amplified. In practice, these ideal conditions rarely apply and two points within the feedforward amplifier are monitored at 20; 30 to determine the degree of similarity between the two signals being monitored. The degree of similarity is determined by a correlator which includes frequency multipliers Fig. 2. The outputs of which are used to adjust the amplitude and phase of at least one of the signals being monitored, so as to reduce the degree of similarity. When the amplifier is set up perfectly, so that no distortion is present in the output signal, the degree of similarity between the two monitored points is substantially zero. A feedforward amplifier contains two separately identifiable stages 12 and 13, in the first 12 of which the distortion is determined, and in the second 13 of which the distortion is removed from the output signal, and the correlation technique is applied individually to both stages of the amplifier. <IMAGE>
