Title: Chair lift or cableway with coupling clips
Inventor: BROCHAND MAX
IPC: B61B12/12
Filed: 1981-12-21
Granted: 1985-04-25
Abstract: Aerial monocable chairlift or gondola lift having detachable grips for coupling the chairs or gondolas to the continuously moving cable.

Title: Cutting insert for deep grooving
Inventor: GOWANLOCK THOMAS WILLIAM
IPC: B23B27/04
Filed: 1981-12-14
Granted: 1986-05-07
Abstract: A cutting insert for use in a deep grooving tool is formed from an elongated generally rectangular block of cutting material having a cutting end. The insert includes a straight cutting edge, disposed perpendicular to the longitudinal axis of the insert and is defined by the juncture between one side edge of the cutting end and the leading surface of the insert. The leading surface of the insert, which is configured for controlling chips, includes a V-shaped ridge, spaced from the cutting edge and oriented such that the apex portion thereof is disposed closest to the cutting edge. The leading surface of the insert further includes a groove, which is contiguous with the V-shaped ridge, and extends towards the cutting edge. In one preferred embodiment of the subject invention, the groove is substantially planar in configuration and extends to and is contiguous with the cutting edge. In a second embodiment of the subject invention, a planar land area is provided between the cutting edge and the groove for effectively spacing the groove from the cutting edge. In the latter embodiment, the groove is defined by two arcuate segments which are disposed in mirror image relationship about a central rib. In use, the insert functions to reduce the width and length of said chips thereby increasing the efficiency of the grooving tool.

Title: Method and apparatus for transmitting an image
Inventor: NICOL RICHARD CHARLES
IPC: H04N7/26
Filed: 1982-07-21
Granted: 1984-11-08
Abstract: A method and an apparatus for transmitting an image in which the image is sampled at a first plurality of points. The samples are then subjected to a two-dimensional unitary transform to produce a second plurality of transform coefficients, the second plurality being smaller than the first plurality and being obtained either by selection or truncation of the transform to provide the coefficients containing only the lower frequency components of the image. The transform coefficients are transmitted and on receipt converted by the inverse transform to a second plurality of image samples. Suitable transforms include the Hadamard and the discrete cosine. The image transmission is described as part of a viewdata system.

Title: Slurry pump
Inventor: DWYER ANTHONY FREDERICK
IPC: F16P3/08
Filed: 1983-01-24
Granted: 1986-10-16
Abstract: A slurry pump has a hopper containing slurry. A pumping cylinder containing a piston communicates with the hopper through the hopper wall. A delivery tube is swung into and out of register with the cylinder. Slurry is drawn into the cylinder by the piston and out through the delivery tube. The pump is controlled by a lever which has a central neutral position and two operating positions. Dangerous moving parts are covered by a guard mounted on hinges. An arm on the guard engages a slide which has a channel. If the guard is moved from its closed position, the arm slides the slide so that the control lever enters the channel and moves to its neutral position. The external moving parts include releasable clamping means for sealing the junction of the delivery tube and the cylinder while slurry is being transferred from the cylinder to the tube.

Title: Method of and device for making colour separations in one-colour printing
Inventor: JUNG EGGERT
IPC: H04N1/48
Filed: 1983-12-14
Granted: 1987-12-10
Abstract: The system uses line-by-line optoelectronic scanning to obtain colour values for three basic colours. A recognition circuit provides a colour tone recognition signal representing the difference between a scanned tone and a printing tone. A mixer combines a selected colour signal with a voltage value representing white to obtain a control signal for the printing element recording each printing point. The mixing ratio of the colour signal and the white voltage level is dependant on the colour tone recognition signal. The latter is pref. combined with the corrected colour signal to provide the printing control signal.
Patent DE-3374429-D1 (DE)
Title: Guidance system for a moving body viewing its surroundings and correlating
Inventor: BROWN GEORGE
IPC: G01C21/00
Filed: 1983-04-26
Granted: 1987-12-17
Abstract: The guidance system enables a moving body (1) e.g. an aircraft or missile, to be guided to a predetermined location by allowing the body (1) to view its surroundings and to compare the viewed scene (8) with a reference pattern (eg 24) stored on the body. A number of individual reference patterns (24,25,26,27,28,40 etc) are stored, and each reference pattern corresponds to an area of the surroundings (e.g. 24) which is very much smaller than the field of view (8) and thus the body identifies its position by correlating its field of view (8) with one of the reference patterns (e.g.24). To enable the body (1) to identify its position (30) even if it deviates from an expected path (31), a number of reference patterns (e.g. 24,25,27,28) are laterally displaced from the expected path (31). The extent of the lateral displacements reduces with decreasing distance from a predetermined locaction (40) to which the body (1) is to be guided.
