Title: Flexible packaging boxes of non-shrinkable plastics - which are sealed strengthed by shrinking plastic sleeve over body cover base parts
Inventor: FRESNEL JACQUES
IPC: B65D77/00
Filed: 1974-10-30
Abstract: Flexible packaging boxes consisting of non-shrinkable plastic material are strengthened and sealed by (a) fixing the base part onto the cylindrical or oral body of plastic sheet, (b) filling the body with the material to be packaged; (c) fixing the cover on the body; (d) pulling over the box a sleeve of shrinkable thermoplastic material, this sleeve having a slightly greater diameter than the cover and base part, and a greater length than the total distance separating the external walls of these parts; and (d) thermally shrinking the sleeve in an oven, so that it adapts exactly to the contours of the box, and closes over the cover and base part. Provides an excellent seal, and considerably increases the strength/rigidity of the packaging box. The body of the box is resistant to impacts and bursting, even when made of thin plastic sheet.

Title: Pulse code modulation circuit for telephone applications - provides high signal to noise ratio using ramped analogue technique
IPC: H03M1/00
Filed: 1975-09-30
Abstract: A coding circuit for telephone communications systems uses PCM techniques where amplitude compression is used following normalised characteristics to improve the signal to noise ratio at low transmission levels. A reference voltage is compared against sampled sections of the unknown level transmission resulting in an 'anamorph' of the normalised coding characteristics and consists of a unique ramp of eight successive slopes (Sk) between zero and a maximum level, this being >= the highest level occuring in the sample. Each of the four final slopes has twice the duration of each of the first two. A pulse counter processing the code is fed by a variable oscillator whose frequency falls to half value during the period of one sample segment.

Title: Shaft coupling with torque limiter - has blocks against drive shaft which press against half coupling to transmit torque by friction
Inventor: BELPERIN GERARD
IPC: F16D43/18
Filed: 1975-10-27
Abstract: The driving shaft (1) of the torque limiting coupling has two parallel end flanges with a recess (6) formed between them. A number of blocks (5) which form circular segments can slide radially for a very small distance between the end faces of the recess (6). The blocks (5) have a slot (7) which fits around the bolt (10). As the shaft (1) rotates the blocks (5) press against the bore of the half coupling (3). The friction between the blocks (5) and the half coupling (3) transmits the torque from the driving shaft (1) to the driven shaft (4). The torque is limited by the materials of the contacting surfaces and by the mass of the blocks (5) and the torque increases with increasing speed.

Title: Alternating current agglomeration of colloidal solids in suspension - used to purify industrial effluents
IPC: C02F1/00
Filed: 1976-07-13
Abstract: A continuous process and plant for agglomerating solids, partic. of colloidal dimension, from suspension in a liq. to facilitate sepn. and purificn. of the liq. is claimed. The liq. flows continuously between two electrodes operating on A.C. at 0.2 to 800 HZ and with a current density of 1.24 to 93.0 amps/dm2, while the liquid is agitated to a turbulence equivalent to a Reynolds number of about 10,000. The turbulence is created by injection of a fluid, e.g. compressed air and/or recirculated liq. and is used to promote between the electrodes a fluidised bed of electrically conductive particles, e.g. cylindrical pellets of graphite with a nominal dia. of 3.2mm x 4.8 mm long. Used e.g. sepg. colloidal graphite pollution from aqueous suspension and treating sedimentation sludge from paper mill effluent., enhanced flocculation of solids and extended periods of trouble-free operation are obtd.; erosion of electrodes is reduced to only 0.2% of that in D.C, cells. Treated water is clarified and deodorised by the hydroden peroxide. The electrodes are kept clean by scrubbing action of particles in the fluidised bed.

Title: Depth regulator for dredger on pivoting boom - has pulley to keep boom suspension cable tension constant despite sea-swell
IPC: E02F9/06
Filed: 1976-12-01
Abstract: The dredged-depth control system is for use in the dredging of shipping channels and compensates for the effects of sea-swell to maintain a constant dredged depth.
