Title: Crack detection in electrically conducting specimen - by comparing voltage drops of AC through test and reference specimens
Inventor: BAUS ALAIN
IPC: G01N3/06
Filed: 1974-10-11
Abstract: Detection of cracking in an electrically conducting test specimen subjected to a mechanical stress involves determination of the resistivity variations in a zone of maximum stress by means of a current passed through the zone. The detection equipment comprises a first speciment which is subjected to the mechanical stress by an appropriate method. A second speciment which is similar to the first is placed near it in order to be at the same temperature and to serve as a reference. A source of a.c. passes through the two specimens connected in series. Measurement contacts placed on each speciment on either side of the zone of interest sample the potential difference created in this zone by the passage of current; the two potential differences are compared to defect any large differences due to cracking.

Patent FR-2257879-A1 (FR)
IPC: F24S10/50
Filed: 1974-10-29
Abstract: A panel having multiple tubular passages extending therethrough and fitted on each end with a fluid tight hollow header. Apertures through one side of the headers place the tubular passages in communication with the interior of the headers. Fluid pumped into one header flows through the tubular passages to the other header, exchanging heat with the environment surrounding the panel as it passes therethrough. The panels are formed to provide a flow restrictive feature at the ends of the through fluid passages so that substantial flow will exist in all passages in all panels in an array of panels. One method for obtaining a fluid tight bond between the headers and the panel involves a forming process utilizing a heated die applied to the panel ends, and a subsequent panel and header material melting process followed by imposing pressure contact between the formed panel ends and the headers to thereby effect a permanent bond or weld.

Title: Emergency lock for doors - has flat plate actuator which rotates the square plug in the lock nut
IPC: E05B65/10
Filed: 1974-12-16
Abstract: The emergency actuator is designed for a lock with actuating nut with square hole. This lock is actuated by rotating the nut with a square plug which is inserted into the hole. The emergency actuator rotates this plug merely by exerting pressure on the actuating plate. This ensures that no complicated reasoned effort is needed to open the door in an emergency situation. The actuating plate is pivoted about a pin on the actual lock plate and also on the lock plate which does not house a lock but acts as a stabiliser. The rotation of the plate in the opening direction actuates a chain which in turn rotates a sprocket wheel. The sprocket wheel rotates a square pin.

Title: Multichamber pneumatic tyre with supply and discharge ducts - to all chambers, and limited communication for pressure balancing
IPC: B29D30/08
Filed: 1975-03-28
Abstract: A multi-chamber pneumatic tyre has all chambers supplied through individual non-return valves from an air supply duct running circumferentially through the tyre, all the chambers being also connected by individual non-return valves to a common, circumferential discharge air duct; both these ducts are connected to a common principal valve used for inflating and deflating the tyre. This principal valve comprises a valve chamber connected by passages to the air supply duct and air discharge duct resp.; a movable valve body inside this chamber, when in its normal posn., prevents any communication between these two passages and but, when moved to a second posn., provides communication between them. During inflation and adjustment of the tyre pressure, the valve can be moved to the second posn. so that excess pressure in any one chamber, discharging into the discharge duct can pass into the supply duct and thus enter some or all of the other chambers; in this way a balance of pressure throughout all the chambers is obtd.

Title: Electronic electrotherapy equipment - opposes signal at base of transistor forming part of multivibrator assembly
IPC: A61N1/08
Filed: 1975-05-13
Abstract: The equipment initiates and stops oscillation of multivibrators and oscillators accurately during cardiac systoles.

The electronic circuits used can be integrated, thus allowing operation at very low voltage. The multivibrator used can be monostable, back-coupled to form a multivibrator, being stopped and restarted by a single rack-pattern signal. Square oscillations can be obtained, of equal or unequal duration as desired by the users.

Title: Bone fracture or disease treatment device - has needles secured across brace with threaded distractors holding brace frames apart
Inventor: VOLKOV M V
IPC: A61B17/64
Filed: 1975-06-12
Abstract: The appts. is for surgical treatment of bone fractures and diseases. Two pairs of needles are each driven through one of the bone fragments being aligned.

Title: Vapour treating dyed polyester textiles - to effect removal of dye in certain regions
Inventor: BUJADOUX RAYMOND
IPC: D06P5/15
Filed: 1975-08-04
Abstract: Polyester based textile articles are dyed and then printed with e.g. a paste according to a pattern. The textile articles are then vapour treated at 100 degrees C so that the paste removes the original dye to leave a colourless area which can be subsequently dyed a different colour. The textile articles may be of fibres of butylene polyterephthalate which may be modified by 6% of a polyglycol.
