Title: Short cct. detector - protected DC line shunted, current growth measured against time
Inventor: CASTEX JEAN-PIERRE
IPC: H02H3/44
Filed: 1974-12-13
Abstract: A short circuit detector employs a method which involves shunting a D.C. line which is to be protected. The shunt signal is then passed through an amplifier (2), a filter (3) and a detector (4). The detector is an operational amplifier whose function is to measure the growth of the current within a given interval of time. The output of the detector goes into a comparator which has a defined threshold. When the output signal of the detector is greater than the threshold signal, a relay is energised disconnecting the original supply line. For an A.C. line, the shunt signal needs to be rectified.

Title: Diffraction grating manufacturing process - involves use of two coherent light beams to produce up to 10000 fringes per mm
IPC: G03F7/00
Filed: 1975-04-29
Abstract: Diffraction gratings with a blaze favouring a particular diffraction order are mfrd. using interference effects on a photosensitive layer (2). The photosensitive surface (2) is submitted to the simultaneous action of two coherent light beams (3, 4) coherent to each other, and at an acute angle to the surface. The two beams cross in a zone near to the surface. A developer is then applied to the photosensitive layer (2) which dissolves the parts on the layer transformed (or not transformed), by the light, when the photosensitive layer is positive (or negative). Thus saw tooth grooved profiles are formed. In the zone where the two beams (3, 4) cross there is a medium with an refraction index greater than that of air or even greater than that of the photosensitive layer.

Title: Dispenser for adhesive tape etc. - has rollers to unwind required length and hand operated blade to cut off length
IPC: B26D1/10
Filed: 1975-05-29
Abstract: The roll of tape is laid on a horizontal partition inside a box beneath a lid. Its end is passed through a slot in the partition and then through two sets of rollers to the outlet slot. The two pairs of rollers are geared together and rotated by a handwheel (1). Two of the four rollers are on pivot mountings. When the required length of tape has been unwound, it is cut free by moving a blade support block across the case. This rotates a pinion inside the block against a rack, and the resulting pinion rotation imparts a complex oscillating and pivoting motion to the blade.
Patent FR-2281815-A1 (FR)
Title: Cooling process for concrete sections of bridges etc. - lowers temperature of unset concrete and prevents localised freeze phenomena
IPC: B28C5/46
Filed: 1975-07-23
Abstract: Concrete is cooled by adding liquid N2 during mixing of the aggregate and cement with water, pref. by spraying it into the mixer. In addition, the aggregate and/or cement may be cooled with liquid N2 prior to mixing. Temp. is thus reduced by approx. 10 deg.C without the occurrence of localised freeze phenomena. A period of 1-2 mins. is completely sufficient for the process. The process requires less expenditure on site than the method of adding pounded water ice, as only an insulated tank for the liquid N2 and a supply pipe to the mixer need to be installed.
