Patent FR-2309735-A1 (FR)
Title: Hydraulic turbine speed control - has tachometer regulating air flow into hollow shaft for exhaust in casing to vary water effective density
IPC: F03B15/00
Filed: 1975-04-30
Abstract: Water at the level (N1) flows into the turbine inlet (1) and drives the rotor (R). The water then flows out through the outlet (2). The rotor (R) drives the shaft (A) the reduction gear (E) and a tachometer (T). The shaft (A) is hollow and air enters the holes (3) and flows out through the holes (4) where the water pressure is sub-atmospheric due to its velocity. The mount of air flowing is controlled by the tachometer (T) so that it increases with speed. The increased flow of air reduces the effective density of the water and so reduces the turbine speed.

Patent FR-2311876-A1 (FR)
Title: Reading a pattern to programme a Jacquard tape - esp. for circular knitting machines, without need for decoding
IPC: D03C17/00
Filed: 1975-05-22
Abstract: For the prodn. of a perforated tape corresp. to the reading of a pattern which is to be reproduced on a circular knitting machine, the points of the design are read from left to right in the direction of the weft and from bottom to top in the direction of the warp, using a Teletype ASR-38(RTM) or similar device. The keys are pressed to perforate the paper tape according to the colours, the same key being always used for the same colour, so that it is not necessary to decode before perforating the steel tape necessary for the working of the Jacquard selector mechanism, since the intermediate paper tape is the exact image of the finished steel tape. The pattern to be read is divided into sections all of which have the same number of rows. The details corresp. to a section are posted to a memory, and the paper is perforated only after the reading of a section is completely finished, during the reading of the following section. The technique is partic. applicable to Dubbed machines with Wevenit (RTM) patterning arrangements, type A24, A36, and Terrot RMA machines. Reading costs are saved. An additional key is fitted on the machine which moves up the rule row by row to assist reading off.

Title: Furnace with burner group ramps - has alternate flow rate burners for inversion of direction of travel of flame around area to be heated
IPC: F27D7/00
Filed: 1975-11-12
Abstract: The device comprises a furnace in which the heat generated by a group of burners situated on the furnace front wall is recirculated evenly over the area to be heated. The inversion of the direction of travel of the flames is caused by burner ramps situated independently on the furnace wall. The ramps are formed in two series of which each has a different flow rate. They vary alternately from burner to burner, the size of which depends upon the heating area of the furnace. The burner ramps are located at either side of the heating surface permitting the heat to flow down the outside and back along the centre.

Title: Wheel nut and cap prodn. - by compressing cap and nut between welding electrodes and generates current impulse
IPC: B23K11/30
Filed: 1977-06-27
Abstract: The process produces a wheel nut with polygonal spanner face and a conical end bearing against the wheel, together with a cap of corrosion-resistant steel, enclosing the spanner faces and the end opposite the conical one, ending near the join between the latter and the spanner faces. A first electrode is pressed against the conical nut end and a second one against a portion of the cap bearing directly against the nut. An electrical impulse is generated between the electrodes, having a duration of 30 micro-secs. and a current peak value >50,000 amperes. This forms a weld between cap and nut at a point close to where the second electrode bears against the cap, causing no negative metallurgical alterations in the cap materials.
