Patent IT-1216923-B (IT)
Inventor: BIHY LOTHAR
IPC: B44B7/00
Filed: 1987-04-07
Granted: 1990-03-14
Abstract: Markings have to be applied to the surface (41) of a mineral fibre web (38), said markings being arranged transversely to its length or to its direction of movement. For this, a cylinder (1) is provided with peripheral heating zones, in the form of heating rods (26), corresponding in shape and position to the markings to be applied, said cylinder (1) rotating at a speed whereby the rods (26), or marking ribs (30) provided on the latter, effect the rolling essentially without any slippage on the surface (41) of the mineral fibre web (38). The heating rods (26) or marking strips (30) are made of metal and are electrically heated, by an internal tubular heating element (31), to such a temperature that when contact is made with the surface (41) of the mineral fibre web (38) a flat decomposition zone (43) is created which corresponds to the contour of the marking strips (30), in which zone the binder of the mineral fibre web (38) is decomposed and by changing colour produces the optically visible marking line. The cylinder (1) can be driven either by a d.c. motor synchronously with the line speed of the mineral fibre web (38), or it can also be driven by entrainment with the surface (41) of the mineral fibre web (38).

Title: Evaluating formations traversed by borehole
Inventor: SCHWEITZER JEFFREY S
IPC: G01N/
Filed: 1980-04-16
Granted: 1986-10-01
Abstract: A method is for obtaining a display of an output parameter trace over a depth interval indicative of geologic formation characteristics from borehole derived raw data. Firstly actual values of measurement parameters are derived over the depth interval. Values for the output parameters over the depth interval are assumed and theoretical values of the measurement parameters over the depth interval are calculated. A trace of the assumed output parameters is displayed over the depth interval. Also displayed, for the depth interval, in juxtaposition, are representatives indicative of a trace of the actual values and a trace of the calculated theoretical values. The degree of agreement between these traces is indicative of the reliability of the trace of output parameters. The invention provides for evaluating formations traversed by a borehole, and takes into consideration most, if not all, of the information available, including a-priori information.

Title: Long-acting pyrethroid insecticide compositions - contg. a vaporisation-modifying agent e.g. butyl stearate
IPC: A01N53/00
Filed: 1977-03-23
Granted: 1986-01-27
Abstract: New compositions for the controlled and prolonged volatilisation of a pyrethroid insecticide contain a mixture of at least one pyrethroid insecticide and at least one volatilisation modifying agent. Addition of volatilisation-modifying agents lowers vapour pressure of the pyrethroid preventing premature decomposition, so that evaporation from electrically heated volatilisation devices can be extended for e.g. 8 hrs., thus ensuring continuous insecticidal effect. Typical pyrethroid insecticides include 3-allyl-2-methyl-cyclopent-2-en-4-on-1-yl dl-cis/trans-chrysanthemate and 5-(2-propargyl)-furfuryl dl-cis/trans-chrysanthemate. Typical volatilisation-modifying agents include butyl stearate, didecyl adipate, ethylene glycol benzoate and tricresyl phosphate.

Title: DC transmission line excess voltage protection - comprises excess voltage eliminator across thyristor gate to protect rectifiers
Inventor: GILIM A
IPC: H02M/
Filed: 1975-06-18
Granted: 1981-01-20
Abstract: A method for protecting rectifier for d. c. transmission lines from excess voltages, includes application of an excess voltage eliminator with series connected ballast resistor. The thyristor gate of the rectifier is allowed to be triggered once at the response-time point of the eliminator, and then the normal operation of the rectifier is re-established. This method of protecting transmission lines results in a reduction of the time during which the consumers power supply is interrupted in response to the eliminator action in preventing excess voltages.

Abstract: A method and apparatus for grounding multi-layer insulations (MLI) by electric contact, of either of each layer with the other or of all the layers with the underlying structure by means of one or more points of attachment of mechanical type. This makes it possible to simplify the construction procedure and increase the reliability. This method is essentially carried out in the following manner: The layers (Fig. 1) which form the multi-layer insulations (6), (7), (8) are metalized on both faces and have holes (9) which are also metalized. All layers are contacted with each other and with a part of the attachment system (3) which is also electrically conductive. The other part of the attachment system (2) is positioned on the structure (1) in such a manner as to permit the passage of electric charges. By contacting the two parts of the attachment system (2) (3), the multi-layer insulation is grounded with the structure. The invention lies within the technical field of passive thermal protections, especially for space structures (space apparatus and systems etc.). The object of the invention is to permit the removal of electric charges on multi-layer insulations.

Title: Method of pressurising fire extinguishing systems - first gas supply adjusts valve in second gas supply
IPC: A62C/
Filed: 1974-12-06
Granted: 1978-07-20
Abstract: The system gives rapid delivery of the carbon dioxide gas used as the propellant without icing up of the regulating valve used. The charge is held in a tank and kept at the same pressure as the feed line. A bleed taken from the tank is led to a control valve where the tank pressure acts against a diaphragm and a spring loaded plunger to regulate the inlet of gas through the feed line. When required, the gas is discharged directly into the supply pipe. The tank refills automatically as its pressure drops.

Abstract: 1,032,304. Locking devices. V. CORNARO. June 5, 1964 [Oct. 3, 1963], No. 23516/64. Heading E2A. A locking apparatus for a container for valuables comprises a lock 5 disposable in and removable from a wall portion 1 of said container in the unlocked condition of the locking apparatus, and a locking bolt 14 carried by said wall portion, said lock comprising a housing and a locking bolt actuating mechanism, said locking bolt being displaceable by said mechanism into a locking position only after insertion of said lock in said wall portion. In the embodiment shown the wall portion is the door 1 of the container with a recess 3 for receiving the lock actuating mechanism 5, the mechanism being held in place by a leaf spring 6, a shoulder 7 of which engages an opening 8 in the rear wall 1b of the door. The element 10 comprises a slide member which is displaced vertically out of the housing 4 by means of a key. In the upper part of the door there is a bolt 14 displaceably supported for vertical upward movement within a sleeve 15. The bolt has a shoulder 17 which bears against a door ledge 16 in its lowest position and a surface 14a which bears against the upper surface 10a of the slide member 10 so that on moving the member 10 upwardly the bolt 14 is simultaneously moved upwardly to protrude from the door wall into an opening in the frame of the door. During unlocking the slide member 10 is pulled downwardly allowing the bolt 14 to be withdrawn into the door under its own weight. In another embodiment the lock actuating mechanism has a further bolt which co-operates with the slide member 10. The slide member 10 is formed with an inclined slot in which a cylindrical pin rigidly connected to the additional bolt slides so that when the slide member extends the bolt 14 it also extends the bolt 23 (Fig. 3, not shown). There may also be provided at least one additional bolt in the door preferably moving vertically but extending from the bottom of the door. The two bolts may be operated simultaneously by the horizontal movement of a double wedge member, a toggle device the two links of which are connected to the slide members or a rotatable cam disc which co-operates with rollers on the inner ends of the bolts.
