Title: Flat telephone type aerial cable support - uses flexible clamp which also acts as vibration damper
IPC: F16L3/137
Filed: 1973-06-06
Abstract: Cable support, in particular for an insulated cable, comprises, in combination, a fixing element such as nail, bolt, hook etc, a support piece with a slot for engaging into a fixing element, and a clamp made from flexible material.

Patent FR-2249377-A1 (FR)
IPC: G04F5/06
Filed: 1974-10-24
Abstract: In addition to an oscillating circuit constructed as a clock pulse generator (91) and having a temperature frequency response as low as possible, the time-measuring instrument has a further oscillating circuit (92) which has a temperature frequency response deviating therefrom and preferably higher. A counter (98) counts the pulses of this further oscillating circuit and a temperature-dependent signal is formed by arranging for the counter results to be stored in a memory during a period which is essentially determined by a time counter (912) driven essentially by the clock pulse generator (91). Said signal is transmitted periodically to a frequency converter (91) whose output signal is used to correct the signal transmitted by the clock pulse generator to a reduction mechanism (911) which drives the time counter (912). At least some of the said circuit parts consist of CMOS integrated circuits.

Title: Polycrystalline diamond body prodn. - by epitaxially forming diamond-graphite coat on particles and sintering at high temp. and press.
Inventor: FEDOSEEV D V
IPC: B01J3/06
Filed: 1975-10-08
Abstract: Prodn. of polycrystalline diamond bodies by coating individual diamond particles with graphite, and sintering a suitable shaped agglomerate under pressure whereby the graphitic domains are converted into the diamond structure. The diamond-graphite coating is formed on the particles by epitaxial deposition. The subsequent heating and compressing of the agglomerate results in the formation of a strong compact body free of graphitic inclusions. The epitaxial deposition takes place in a stream of a carbon-contg. gas. The gas stream is stopped before a purely graphitic surface layer is formed. The initial deposit has the diamond structure; then a mixed layer is formed; and finally a purely graphitic structure. These bodies withstand dynamic loading, so that they can be used as drill heads, cutting edges of metal-working tools, metal wire-drawing dies, etc. The starting material may contain even very small particles (1 mu), in contrast to the known process.

Title: Successive fixed image publicity display - uses photoelectric detector to control position of roller driven display band carrying pictures
IPC: G09F11/22
Filed: 1975-12-18
Abstract: The successive fixed image publicity display uses a flexible band. On this band (12) are the images (12a) to be displayed. The band (12) is moved past a presentation zone by a band transport and tensioning system. Movement of the band is stopped each time one of the displays enters into the presentation zone which has dimensions equal to that of the display. The band (12) transport and tensioning system uses two rollers (2a, 2b). These rollers (2a, 2b) are mounted on parallel axes onto which are wound the two ends of the band (12). A motor system drives one of the rollers at a given rate. Braking means, which are adjustable operate on the other roller. A photo electric detector (13) is used to note the passage of the display with respect to the presentation zone. The detector (13) actuates means which interrupt the drive motors for a determined duration, when the display is correctly phased in the presentation zone.
