Title: Monochromatic filter for seismic signals - generates cancellation signal equal in amplitude and phase to interference
IPC: G01V1/36
Filed: 1975-03-19
Abstract: An electronic filter removes approximately sinusoidal parasitic or interference waveforms from signals received by geophones during seismic exploration. The filter mechanism is based on the use of a second signal having the same frequency and amplitude as that of the interference, this signal being used to cancel the unwanted one. The phase and amplitude of the two signals are compared providing control signals correcting any dissimilarity. A third reference signal enables the basis of further phase correction to be derived from its comparison with the residual waveform. Analysis of phase and amplitude relationships is obtained by manipulation of pulse trains having frequencies which are multiples of the interference.

Title: Expandable PVC coatings for generating braille print - by selective heat up of surface printed patterns
Inventor: BRAND GERALD
IPC: B41M7/00
Filed: 1976-06-30
Abstract: Print detectable by blind persons is produced by printing the required (Braille) patterns on to a microporous plastic coating on a suitable (paper) support and then heat-treating the surface to cause local expansion of the printed zones to create patterns of raised relief. The print pattern can be rapidly reproduced for economic printing of books. Different texts may be applied to opposite faces of the same page (unlike use of embossed patterns). The degree of local expansion may be adjusted by varying the relative darkness of the printed pattern and hence heat absorption.

Title: Conveyor-distributor for cutting tuber crops esp. beets - with mobile rake for loading from silo and attachments for coupling to tractor
Inventor: RABAUD CLAUDE
IPC: C13B5/06
Filed: 1976-11-04
Abstract: Conveyor-distributor enables raw foodstuffs to be taken from a silo, or be received into a hopper, to be cut up and then distributed ready cut. The hopper is fitted with a conveyor, supplied with rakes, and driven by chains around the drums. The hopper can be carried by the three-point coupling of a tractor. Mobile rakes draw the raw materials onto the coveyor which carries them towards the discharge end, in the direction of the arrow. An arched opening and a rotating disc, fitted with knives, are located at the discharge end while the support of the disc is retractably mounted on two oscillating arms. A deflector prevents any debris from the roots from falling on the ground. The drive for the cutting disc is by a bevel drive and a shaft; this is itself driven by toothed wheels through a chain. Starting with beets or other tubers it is possible to feed cattle with chopped beets by using only one machine for transporting, cutting and distributing them; it may also be used for removing them from a silo.
