Title: Image processor normalising and enhancing image contrast - uses programme statistical pipe-line processor to calculate new brightness for each point in image
Inventor: ROCHE CLAUDE
IPC: H04N1/407
Filed: 1974-09-16
Abstract: The image processor normalises and enhances the contrast of an image using a pipe-line processor programmed to perform a statistical function on each image poit to yield a new value. For each image point the mean amplitude and the variance of the immediately neighbouring points are calculated in two processors. A histogram of mean amplitudes is stored, as is a histogram of amplitude variance, above a threshold. For each image point these histograms are combined in a statistical function whose form is determined by a read-only-memory. From the results of this process a look up table is derived which is used to transform each incoming image point into an enhanced point.

Title: Soft half tone photographic printing method - modifies dimensions of points which compose screened subject
Inventor: DELAGARDE YVES
IPC: G03F5/02
Filed: 1976-01-05
Abstract: The method concerns the preparation of half tone negatives for soft halftone prints. The method superposes two types of exposure of a photographic film through a screen. One of these types corresponds to at least one exposure of a film to a luminous source. This type of exposure is carried out in conditions such that the negative is produced in a uniform fashion. These conditions do not exceed that which will lead to the formation of maximum surface area points. Each of these points corresponding to a mesh of the screen. The other of the two types corresponds to at least one film exposure of the subject to be reproduced.

Title: Axial locating bearing for flywheel shafts - uses elastic O:ring in hub to retain torus fixed to shaft
IPC: G11B15/18
Filed: 1976-02-12
Abstract: The flywheel shaft (10) is rigidly mounted in a boss (14) at the flywheel (11) centre. A shallow circular depression (19) is formed around the boss to keep the fitting compact. On the boss is located a washer (16), with a torus shaped periphery (17), retained in place by a circlip (12). A hub (20) is fixed in the support wall (P) and has a stepped series of bores (21, 22,23) which clear the external diameters of the flywheel location fittings. At the end of the hub nearest the flywheel is cut an internal groove (24) which loosely retains an elastic O-ring (25) having a slightly smaller internal diameter than the external diameter of the torus. When the shaft is inserted in the hub and forced home, the torus expands, and is then retained by, the O-ring.

Title: Multiplexing system for telephone lines - has double modulation for twelve lines with pass band filters in first modulation
Inventor: COLIN JEAN EDOUARD
IPC: H04J1/04
Filed: 1976-05-14
Abstract: A multiplexing system for telephone lines is used in carrier current equipment. It has a double modulation and is aimed at reducing the cost of first modulation filters. The system has twelve lines. It consists in transposing twelve voice frequencies bands, situated between 0.3 and 3.4 kHz, into a single frequency band of 48 kHz, between 60.6 and 107.7 kHz. It has a first modulation of two, three or four carrier waves and a second modulation to give a total modulation of twelve carrier waves. The two, three of four lines are coupled by means of a filter with, correspondingly, two, three or four pass bands with the same attenuation in each band. The gap between the carrier waves of the first modulation is equal to the voice frequency band of 48 kHz divided by the number of first modulation carrier waves. There are correspondingly six, four or three assemblies which provide a second modulation to give the twelve carrier waves after coupling and filtering.

Title: Supporting layer for roads - comprising mineral granules hydraulic binder and coarse degradation resistant granules
IPC: E01C3/00
Filed: 1976-05-24
Abstract: Material for forming the foundation of support layers of roads, comprising a mixt. of mineral granular and a hydraulic binder or similar such as cement, strongly hydraulic lime, quicklime and slaked lime, contains in addition a degradation resistant mineral of much coarser grain size. The compsn. contains 4-15 pts. wt. hydraulic binder, 10-35 pts. wt. coarse mineral, 1-9 pts. water, all wrt. the total mixt. The mixt is prepd. by intensively mixing the active binder with the mineral granules and the coarser granules are added regularly to the mixt. The problems of fissuring due to temp. changes, esp. frost are eliminated, since the hydraulically set mineral can absorb the tensions dye to shrinkage and expansion without causing deterioration of the bituminous road surfacing.

Title: Coded transmission of analogue signals - sampling over variable periods reduces bits to be transmitted
IPC: H04B1/66
Filed: 1976-06-18
Abstract: A method for coding and decoding analogue signals to permit their transmission as telegrams, which is applicable to speech signals, in which test periods of predetermined length are generated and by repeated scanning over each test period it is determined whether any change in the analogue since the beginning of the priod has exceeded a predetermined threshold value (positive or negative). If this change has occurred a code message to that effect is immediately transmitted and the test period is ended. At the end of each test period which has extended to its full duration a code-word corresponding to the change over the period is sent. At the receiver the code words are translated into amplitude changes which are continuously summated. The method ensures the need to transmit the minimum number of bits with adequate signal/noise ratio.
