Abstract: A method for decreasing the density of a substantially closed-cell thermoplastic resin foam material by the secondary expansion thereof. The method comprises increasing the gas pressure within the cells, retaining that elevated cell pressure for prolonged periods and then heating the foam material above its heat plastifying temperature to cause secondary expansion thereof. In an example, a low density polyethylene material was foamed to produce a foam with a density of approximately 0.085 grams per cubic centimeter. This foam was then pressurized with nitrogen and afterward secondarily expanded to produce a foam with a density of approximately 0.036 grams per cubic centimeter.

Abstract: The device for adjusting an electromechanical postage machine (11) comprises a motor (21) driving a driving shaft (23). On the shaft (23) there are arranged mutually independent control groups (28), each associated with a different decade (43) of an input electronic register (42). Each control group is connected mechanically, by means of a transmission (16), to a roller of numerals (13) of a rotary stamp (12) and with an input (14) of an adding mechanism (15). To each control group (28) a coupling mechanism (29) is associated for establishing or breaking a connection between the control group and the driving shaft (23), as well as a blocking wheel (30) which may be blocked by an electromagnetic stopping device (46). Each stopping device (56) is controlled by the "zero" position of a reversible counter (51) which, at the beginning of the adjusting process, takes the input value coming from the associated decade (43) and counts down at the rate of a pulse generator (35) arranged on the driving shaft (23). In the course of an adjusting cycle, the motor (21) rotates in the reverse direction forpositionning the rollers of numerals (13) on "zero" and in the foward direction for adjusting the rollers of numerals (13) on the desired input values. The stopping devices (56) then block the blocking wheels (30) according to the input values, and the coupling mechanisms (29) break the connection with the driving shaft (23).

Abstract: Un joint d'étanchéité à haute fréquence assure un joint électromagnétique entre une première (35) et une deuxième (45) pièces d'une enceinte de blindage. Le joint d'étanchéité comprend des éléments en saillie (37) en forme de doigts hautement élastiques qui sont fixés et en saillie sur le périmètre de la première pièce de l'enceinte (35). L'agencement correspondant relatif entre le joint d'étanchéité et la première et la deuxième pièces de l'enceinte est tel qu'une faible force appliquée sur la première pièce de l'enceinte (35) est contre-carrée par une force de résistance beaucoup plus élevée le long de la dimension longitudinale des éléments en saillie en forme de doigts hautement élastiques (37) lorsque les doigts engagent la deuxième pièce de l'enceinte (43). La force de résistance plus élevée produit une pression suffisamment élevée au point de contact entre les doigts en saillie (37) et la deuxième pièce de l'enceinte (43) de sorte que la surface de la deuxième pièce de l'enceinte (43) cède sous l'effet des doigts en saillie (37). On obtient ainsi un contact électrique fiable entre la première et la deuxième pièces de l'enceinte en perçant la surface de la deuxième pièce de l'enceinte (43) avec le point de contact des doigts en saillie avec la deuxième pièce de l'enceinte.

Abstract: A novel polymer alloy coating is provided consisting essentially of polyphenylene sulfide and an amount of polyimide. The polyimide is produced by the crosslinking and curing of an acetylene terminated aromatic polyimide oligomer resin. The amount of polyimide utilized is sufficient to enhance the adhesiveness of the polyphenylene sulfide to a metal substrate without substantially changing the melt flow properties, chemical resistance and thermal stability of the polyphenylene sulfide. A polymer alloy resin composition is also provided for application to the metal substrate to produce the polymer alloy coating. The novel polymer alloy coating is particularly suitable for coating pipes, particularly pipe couplings for oil and gas well production pipes which are exposed to extreme temperatures, pressures and corrosive environments.

Abstract: After the enciphering of a clear text, arbitrary control characters will occur which are not printable, such as, for example, "return movement of carriage" and "new line". The method of rendering the whole enciphered text printable obviates this disadvantage in accordance with the invention by subjecting all the enciphered characters to an additional processing step. This processing step consists in that the characters of an enciphered text consisting of, for example, 5-bit characters, are subdivided into 4-bit words. The 4-bit words are then extended to a new 5-bit word in a manner such that it is ensured that printable characters are obtained.

Abstract: Methods of making modified polyimide/polyimide- amide foams and the resulting compositions. An N-substituted aliphatic imide is prepared by reacting a suitable aromatic dianhydride with a suitable oxoimine. A polyimide forming material is prepared by dissolving the N-substituted aliphatic imide in an esterifying solvent, then adding a suitable aromatic diamine. This material is dried to a powder or film. A foam is produced by heating the material to reaction temperature for a period sufficient to produce a stable foam. The material melts, then spontaneously expands into a foam which becomes self supporting and cures to a resilient flexible foam. Depending upon heating conditions, a polyimide, polyimide-amide or mixture thereof may be produced, resulting in foams having varying physical properties.

Abstract: A novel pump suitable for use in a water injection system of an internal combustion engine is described. The pump controls the rate of flow of water injected into the engine. The pump includes a variable pressure inducing means for pressurizing the water contained in the pump. The variable pressure inducing means is responsive to negative back pressure developed in the intake manifold of the engine and varies the pressure of the water in accordance with changes in the negative back pressure of the manifold. As the negative back pressure decreases, the pressure of the water increases which in turn increases the flow rate of fluid from the pump into the engine. There is also disclosed a pressure sensitive nozzle for controlling the flow of fluid exiting from the nozzle as a function of fluid pressure. The nozzle includes an auxiliary fluid flow path through the nozzle that has an inlet opening of variable size. The nozzle further includes a pressure sensitive piston that provides a primary fluid flow path through the nozzle. The pressure sensitive piston normally blocks the inlet of the auxiliary flow path. In response to a pressure build up above the predetermined value in the primary fluid flow path of the piston, the piston moves thereby increasing the size of the inlet of the auxiliary flow path as the pressure build up in the primary flow path increases above the predetermined value.
