Patent FR-2175683-A1 (FR)
Title: Enriching granular ores - by removing gangue from granules after drying
IPC: B07B9/02
Filed: 1972-03-14
Abstract: In the enriching of granular structure ores after drying, by eliminating the gangue from the nodules by disintegrating it into fine particles, the ore is projected at a speed V along a plane radial to the axis of a bladed wheel, the speed V being calcd. to give sufficient energy to each granule to loosen the gangue attached to its surface, by the shock. The ore is recovered in an annular channel coaxial with the wheel where it undergoes the impact of the continuously projected ore which produces an attrition of the mass until it overflows from the channel. Below the channel, cyclone tubes separate the fine gangue particles from the ore granules, each being collected in and evacuated from different chambers.

Title: Cultivation of wood-destroying mushrooms - on agricultural waste products
IPC: A01G1/04
Filed: 1972-10-16
Abstract: The growth medium consists of agricultural waste products which are chopped, mixed with water, loaded into containers with provision for aeration and sterilised.

Title: Cathode ray tube glass - contg zirconium dioxide and cerium oxide, for better initial transparency without discoloration
IPC: C03C4/12
Filed: 1972-12-06
Abstract: Glass contg. ZrO2 in addn. to CeO2 is used in a cathode ray tube with a glass envelope, including a glass front pane and a phosphor screen inside this. CeO2 suppresses the gradual discoloration of the tube during use but, in the amt. needed when used alone, also impairs the initial transparency, esp. in the near the UV region. The use of ZrO2 in conjuctiion with CeO2 ensures good initial transparency in and near this region and also very low discoloration. The glass pref. contains 0.5-5 wt.% CeO2, 0.05-10% ZrO2 and pref. also an arsenite as refining agent.

Title: Standard printed format for envelopes - has spaces for address both written and coded by marking or perforation
IPC: B65D27/00
Filed: 1974-11-27
Abstract: The standard printed format is for production of envelopes or post cards. The format consists of a number of spaces allocated to written address, stamps and destination, but also having smaller divisions bearing printed numbers. The sender marks off or perforates these divisions which are coded to give the same information as the address. A knowledge of the code makes it unnecessary for the sorter to be able to read the written information and equally makes it possible for the letters to be sorted mechanically or electronically. It is also possible to arrange an internationally agreed format and code so that no difficulty arises when sorting overseas mail.

Title: Hydrocarbon reformer using recycled combustion gases - mixed with burner combustion air to permit satisfactory use of gas and liq. fuels
IPC: C01B3/38
Filed: 1975-06-27

Title: External vacuum calibration of extrudates - to achieve calibration and high throughput without vacuum pumps
IPC: B29C48/90
Filed: 1975-09-02
Abstract: Equipment for external vacuum calibration of continuous extruded profiles comprises leading an oversized hot profile into an external calibration die passing through one or more water troughs. The die is interconnected with the upstream zone of the trough into which chilled water is injected to be circulated via a baffle towards an outlet at the downstream end of the trough. Recirculating water is also drawn countercurrent through a concentric passage in an extension of the calibration die. The chilled water entering the system continuously exchanges and cools water abstracting heat by contact with the extrudate passing through the calibration die, thus producing suction by contraction to maintain the extrudate in contact with the walls of the calibration die. Device utlises simple equipment and a standard water recirculation pump and chiller. Enhanced cooling rates are obtd., and h ence higher possible extrudated output rates, than systems using stagnant trough cooling.
Patent FR-2295901-A1 (FR)
Title: Thread knotting unit - control element arranged between knotter arm pivot and knotter
IPC: B65H69/04
Filed: 1975-12-22
Abstract: The control unit is arranged on the knotter arm between the swivel bearing of the arm and the knotter head. A single toothed segment is arranged for the drive to the pinion. By the pivoting motion of the knotter arm the pinion comes into the circular path of the segment consequent upon the control drum rotation. The knotter moves in an arc the radius of which is the total length of the knotter arm by which the movement is nearer to a straight line than with known makes. The carrying of the control unit in the centre area of the knotter arm leads to an increased compounding of the control unit movement on that of the knotter. This, apart from advantages in cost by the reduction in size of the cam and the control drum, has the advantage in reliability.

These gauges stop the winch when the discrepancy between the loads on the falls reaches a predetermined value. There can be teeth on the hoist block pulleys, or recesses in them, engaging with the chain links.
