Title: Automatic time delayed seat belt unfastening system - has spring biased pneumatic piston removing block to allow fastening parts to separate in response to shock of collision
IPC: B60R22/32
Filed: 1980-11-24
Abstract: The device responds to the sudden shock of an accident in order to separate two parts. The device includes a female part which is attached to the floor of the vehicle, inside which is a male part. The male part comprises a cylinder with two pegs projecting from opposite sides of the bottom of the cylinder. These two pegs normally fit into recesses to hold the cylinder in the female part. Although the pegs are spring biased to the withdrawn position a block keeps them apart, and in the locking position. A large spring biased pneumatic piston is attached to this block by a further coil spring. In the case of a shock, the piston withdraws the block allowing the pegs to be withdrawn and the two parts of the block separated.

Title: Resistance wire arrangement for electric blanket - has parallel complementary channels, perpendicular to resistance channels, containing wire loops and return cables
Inventor: MORGANDI ARTURO
IPC: A47G9/02
Filed: 1980-12-16
Abstract: The double-woven blanket is divided into double regions sepd. by open or double regions forming parallel channels which house the heating resistances. Along each edge two complementary channels at right angles to the heating channels extend from end to end of the blanket, interconnected by cross-channels, of different width, at least partially aligned with the main channels. The cross-channels are formed between closed woven regions which serve as insulators between the heating formed between closed woven regions which serve as insulators between the heating wire loops in one complementary channel and the return conductor in the other. The heating resistances are easily and quickly inserted into the main channels accessible through the end openings of the aligned cross-channels. For a double blanket the wiring may be in two unconnected circuits.

Title: Intruder surveillance installation using tempered glass - has area formed of panels joined by flexible coupling with conductors in electrical circuit to detect any breakage of glass
Inventor: RUFFINI PIERRE DOMINIQUE
IPC: G08B13/04
Filed: 1981-01-14
Abstract: The glass cover is designed to fit over a position where a sheet of plane glass would not be adequate. A number of rectangular panels (1-4) of tempered glass are joined together by flexible joints (11,12). The joints comprise strips of material with two U-shaped channels to receive the edges of two adjacent panels. Alternatively, the panels may be held together by hooks on end supports, or flexible cord. Each glass panel includes an electrical conductor formed on its surface. The conductors on successive panels are used in series to form a complete loop with a detector. If any of the panels is broken, then the corresponding conductor is also fractured and the electrical circuit is broken, activating the alarm. The structure is cheaper to mfr. than a specially moulded glass panel.

Title: Test probe for monitoring action of cardiac electrode - comprises flexible tube carrying X=ray opaque markings introduced via blood vessel and detectable from outside patients body
Inventor: ROLLET MAURICE EMILE
IPC: A61N1/05
Filed: 1981-04-28
Abstract: The probe is used for determining the characteristics of an electrode which is implanted in a patient's heart as part of a cardiac pacemaker. The detector comprises a flexible tube (1) with a number of markings (3-11) at intervals along it. The markings may be opaque to X-rays, whilst the remainder of the tube is transparent, so that their position may be detected from outside the body. In an alternative arrangement, the markings may be small conductors attached to conducting wires, so that an electrical signal may be applied to them. The tube itself is introduced into the heart through a normal vessel in order to enable the action of the heart to be monitored. To each conducting wire is associated an electrical signal sensor, and that which provides the strongest signal is selected.

Title: Microprocessor controlled strongest signal selector for vehicle radio - compares strength of two carrier wave signals to determine whether modulated signals are identical
Inventor: SCHEUNEMANN JOACHIM
IPC: H03J1/00
Filed: 1981-05-12
Abstract: Two FM tuners and an AM tuner provide inputs to a microprocessor in which two program elements provide frequency control signals. There program elements are connected to a control circuit to command a switching circuit to connect the output of one tunes to the audio circuits and loudspeaker. The IF amplifier outputs for the FM tuners provide signals for shaping circuits for input to the microprocessor. A comparator determines the strongest signal and an identification circuit provides binary output identity signals for the microprocessor. The microprocessor then issues control signals to connect the strongest signal to the loudspeaker. Control signals are issued to provide frequency sweeping on the other tuner to maintain the monitoring process. Manual tuning is performed via the program element in the microprocessor.

Title: Compact three-element UHF antenna for TV reception - comprises aluminium strip formed into square loops mounted on insulated box containing preamplifier
IPC: H01Q19/28
Filed: 1981-05-25
Abstract: The aerial is formed of a dipole (1) consisting of a thin aluminium strip bent to form a square loop whose length of sides is dependent on the frequency. The ends of this strip enter a box made of insulating material to provide support. A reflector (2) and director (3) is formed of similar square loops with sides whose lengths are dependent on frequency. The ends are short circuited and the loops are mounted vertically and parallel to the dipole loop such that the dipole is located between the director and reflector. The box contains a matching circuit for the dipole and allows connection of the coaxial cable to the receiver. A miniature amplifier in this box allows reception of weak signals.

Title: Stirring of molten sodium in steam generator - using vertical row of baffle plates to create turbulent helical flow of sodium along vertical water tubes in generator
Inventor: FABREGUE JEAN-PIERRE
IPC: F22B1/06
Filed: 1981-06-26
Abstract: The sodium flows in a prim. circuit along the external surfaces of numerous tubes. Water in a sec. circuit flows through the bores of the tubes and is heated by the sodium to form steam. The sodium is subjected to a rotational force, and also to alternating centrifugal and centripetal forces so each part of the molten Na flows over a large number of the tubes. The pref. generators consists of a vertical casing down which molten Na flows in counter-current to water flowing up vertical tubes inside the casing. All the tubes pass through a vertical row of horizontal and perforated baffle plates. The baffle plates consist of two types used alternately to drive the molten Na along the desired paths. Elimination of hot zones in the molten Na, even when some of the tubes are blocked, i.e. if a tube leaks, it is blocked off so it receives no water.

Title: Carbon-mon:oxide in air concentration monitor - provides visual and audible alarm signals if mon:oxide in proportion of building exceeds critical level
Inventor: GODIJN WILLEM
IPC: G01N33/00
Filed: 1981-09-14
Abstract: If the proportion of Carbon Monoxide in the atmosphere of a building exceeds 50 parts per million, this detector gives visual and audible warnings. The air is drawn through the body of the detector (1) by a fan (2) mounted on the detector exhaust (8). The air enters the lower chamber (5) which has a water trap (16) which allows condensed water to drain away. The air enters the upper chamber through a small restriction hole (7) in the separating wall (6). This restriction causes a pressure difference of 12mm water gauge which is monitored (3) to ensure that the air-flow is continuous. The air is then filtered (13) and a small proportion flows through the detector assembly (11). The actual detector is a hot wire bridge type which feeds a metering circuit which displays the CO proportion in steps of 15ppm and operates the alarm system if it exceeds 50ppm.
