Patent FR-2232008-A1 (FR)
IPC: H04L17/16
Filed: 1974-05-29
Abstract: A detector for detecting predetermined digital words within a train of signals wherein the digits in the words each have a predetermined time period. The detector continuously samples the train of signals coupled thereto. Samplings are taken a number of times during the interval of a digit time period, and a digital signal corresponding to the sampled signal for each sample taken is stored in a multi-stage storage register. Comparison circuitry compares the digital signals in the storage register with a first predetermined word in a memory circuit. If there is a correlation, the comparison circuit counts for a time period long enough to sample the train of signals and store a new series of signals corresponding to a second digital word. The comparison circuit compares these second digital signals with a second word in the memory circuit. A correlation between theset two words produces a detection signal.

Title: High processing rate interpolator operation - frequency divider cct. avoids error generation when programmed speed exceeds maximum rate
IPC: G05B19/416
Filed: 1975-01-21
Abstract: A digital control circuit provides error free operation of the interpolator circuits of an NC control system when high positioning speeds are required. The interpolator receives geometrical input and generates digital information stored in shift registers and transmitted to outputs for X, Y and Z axis over AND gates. The rate of transfer of pulses via the AND gates is controlled by the frequency of signals from a pulse generator circuit. The frequency of operation is dependent upon the programmed speed of traverse held in a store. If the programmed rate exceeds the maximum permissable processing rate of the interpolator for reliable operation, a frequency dividing circuit generates a lower frequency. The frequency divider is coupled to a pulse generator connected to the interpolator. The contents of the interpolator registers are connected in such resistances.

Title: Appts. for reading glass dosimeters - where ultraviolet lamp irradiates glass sphere and photomultiplier tube measures fluorescence
Inventor: FRANCOIS HENRI
IPC: G01T1/105
Filed: 1975-10-10
Abstract: The novelty is that the dosimeter is mounted on a hollow support which can be located in a recess in a frame carrying the UV lamp; and a filter is located in front of the photomultiplier tube to blockout the UV radiation which has passed through the support and is reflected by the dosimeter. The dosimeter is pref. a sphere with a polished external surface, held by a reflecting mirror in the support which has a side window; the UV light reaching the mirror is reflected towards the glass sphere at 90 degrees to the fluorescence emitted by the sphere via the window and towards the photomultiplier. Alternatively, several photomultiplier tubes may be uniformly distributed at an oblique angle w.r.t. the UV radiation from the lamp. The dosimeter may also have an ovoid or conical shape. After gamma radiation for example, the sphere, made of metaphosphate glass, fluoresces when exposed to UV light, the fluorescence being measured via a photomultiplier tube.

Title: Simultaneous multi subscriber PCM circuit - reduces computation time using sequential addition and subtraction operations at constant rate
Inventor: CALVEZ JEAN-LUC
IPC: H04M3/56
Filed: 1975-12-04
Abstract: A communications circuit uses PCM techniques allowing simultaneous use by more than two subscribers. The design is intended to minimise the computation required and the time involved in the various operations. The switching, carried out at a constant repetition rate, is to an input memory where the non-linear subscriber codes are fed in as groups. The codes are converted to a linear form in an expansion circuit. Computation is by an add and subtract circuit. Each memory group is read twice in succession, alternate subtraction and addition occurring during the two periods. Two registers are employed, one being inhibited during substraction and reset to zero at the start of the addition phase.

Title: Clipping machine feed mechanism - has slide engaging behind free edges of lowest U-shaped clip in stack
IPC: B65B13/34
Filed: 1976-05-07
Abstract: The mechanism feeds clips to the closing head of a clipping machine by extracting the lowermost U-section clip from a stack and thrusting it by means of a slide to the closing tool. The front end of the slide engages behind the corners (30) of the lowermost clip (12) in the stack at the ends of the shanks, and which are left exposed by the next clip above it. The front end concerned can be in two halves, both clear of the path along which the strip to be clipped is guided. These halves (18, 19) can work in lateral guides. The design allows the slide to be made much stronger than is the case with existing designs, and the risk of jamming is thus greatly reduced.
