Abstract: ADDITIVE FOR ROAD SURFACE     ABSTRACT OF THE DISCLOSURE        The additive to a bituminous road cover is to be com-prised of red mud and aluminum hydroxide gel having resulted from partial or complete neutralization of alkali included in sodium aluminum silicate and sodium aluminate; silicon-dioxide gel is also preferably included.  Sodium chloride may be included as an antifreeze.  The neutralization is carried out by means of hydrochloric and/or sulfuric acid, possibly blended with an acidic aluminum salt of these acids.          Following blending of the components, they are dried and ground to below l-mm grain size.  Adding of higher hydro-carbons reduces dust formation.

Abstract: ABSTRACT OF THE DISCLOSURE         A multifilament yarn of an aromatic polyamide, in particular poly-p-phenylene terephthalamide, having a tenacity of at least 15 cN/dtex and an initial modulus of at least 400 cN/dtex is provided with a water-soluble size which is a polyester derived from at least a dicarboxylic acid, at least a diol and a sulphonated dicarboxylic acid, the fila-ments of the yarn having a cohesion corresponding to a Manra number not higher than 40.  The yarn is made by subjecting a non-sized yarn having a moisture content which is lower than its equilibrium moisture content, while under a tension of at most 0.25 cN/dtex, to a continuous wetting treatment with an aqueous solution of a size and subsequently winding the treated yarn into a yarn package.  The yarn package contains a single continuous length of the sized yarn.  The sized yarn is suitable as warp and weft yarn in the weaving industry.

Abstract: SOCIETE NATIONALE DES POUDRES ET EXPLOSIFS               PATENT APPLICATION   Dual-mode propellant charge with a trumpet-shaped channel possessing a star-shaped cross-section An invention of:                 Francis DALET               Bernard DUCOURNEAU                    ABSTRACT       Propellant charge, the combustion of which takes place according to at least two thrust modes, and which makes it possible to obtain at least one acceleration phase and one cruising phase of the self-propelled device equipped with this charge.     The propellant charge is of the so-called "trumpet block" type with radial combustion from a central channel which has a star-shaped cross-section over a length equal to at least one third of the total length of this charge.     In order to obtain at least one dual combustion mode using only a single charge of propellant, that part of the channel which is of star-shaped cross-section possesses at least one zone in which the star of the channel has at least four arms which determine at least two tooth-like sectors of propellant with a large sector angle (A) and at least two tooth-like sectors of propellant with a small sector angle (a), distributed symmetrically relative to the axis of the charge.

Abstract: ABSTRACT OF THE DISCLOSURE         A headrail bracket for mounting venetian blind headrails to ceilings, walls, window frames and the like includes a first and second hanger portions adapted to engage shoulder mounts on a U-shaped headrail where the bracket includes resilient means for moving the hanger portions relative to each other.  The resilient means urges at least one of the hanger portions into locking engagement with a support shoulder.  The bracket has a center web portion and a single flange extending generally downwardly from the web at a location spaced from the second hangar portion.  The resilient means comprises a portion of the single flange cut free from such flange but for one side and cantilevered by said side from a lower part of the flange and extending upwardly toward such web adjacent the flange.  It is therefore capable of being manually pushed so as to flex resiliently toward the plane of the flange to allow disengagement.  The portion of the single flange springs back after the pushing force is released and a part of said portion of the single flange spaced from the point where it joins the flange serves to form the first hangar portion.

Abstract: The indentification system consists of a key comprising a passive memory area (10) and a shift register (9) and a lock which can be coupled with the key. The lock is capable of supplying a set number of pulses causing the code contained in the memory (10) to be loaded into the register (9). The register (9) is subdivided into a certain number of elements linked together but loaded independently. This loading is carried out successively by the multiplexer (111). Transmission of an incorrect number of loading pulses leads, through connection (113), to a modification of the contents of the shift register (9).

Abstract: ABSTRACT OF THE DISCLOSURE            Data correlated to the light reflectance of a maximum toned area and a minimum toned area is recorded to establish standards for monitoring and controlling subsequent copier operation.  A test pattern is imaged onto the photoconductor by controlled illumina-tion levels in a series of steps with the detection of light reflectance from that test pattern being subsequently compared to establish the maximum black and maximum white criteria for storage.  Light reflected from cleaned photoconductor areas and subsequently established toner patches then are used to compare against the original test pattern re-flectance data.  Toner replenishment, controls and machine function monitoring (e.g.:  white copy background, developer operation, etc.) are based on these recorded standards from the test pattern.

Abstract: The invention concerns sleeves for protection against internal contaminations for a gynaecological gun for animals of the type comprising a tubular body, a chamber for storing the product to be injected or aspirated, and ejecting or aspirating means (7) operative through the front end of the body. The problem is to avoid contaminations through the medium of the gun between the vagina and the uterus of the animal. According to the invention, such a sleeve comprises a cylindrical element (13) of flexible and thin material and having an end (13c) which is closed in a sealed manner but is tearable, the length of the sleeve approximately corresponding to the length of the whole of the gun, two substantially parallel slits (16) being provided in the vicinity of the end (13a) opposed to the closed end. The invention is advantageous in the artificial insemination of bovines.

Abstract: IMPROVED AIR SPRAY GUN          Abstract of the Disclosure An improved air spray gun has a spray head assembly comprising separate but interconnectable elements including a fluid nozzle, a fluid inlet fitting and a fluid nozzle retainer.  The elements mount at a forward end of the gun body without any threaded attachment to the body, and air air cap threaded onto the fluid nozzle retainer mounts an air nozzle. Because the elements are separate, the fluid nozzle and fluid inlet fitting may conveniently be manufactured of a corrosion resistant material such as stainless steel, thereby to prevent fluid passages through the same from being corroded by fluid sprayed from the gun. Also, because the air cap threads onto the fluid nozzle retainer and not the gun body, there is no danger of damaging any threads on the body, which could otherwise require replacement of the body.

Abstract: ABSTRACT OF THE DISCLOSURE A control circuit is provided for applying energy to operate a circuit interrupter in response to, and a selected time after, the onset of overcurrent in an alter-nating-current line. The control circuit includes a trans-ducer for producing output current proportional to the cur-rent in the line. The power supply includes an energy storage circuit that stores energy derived from the output current. The stored energy, which is maintained within a first range when there is no overcurrent in the line, energizes the power supply. A time-current trip signal generator cir-cuit responds to output current representative of moderate overcurrent in the line by producing a trip signal after the passage of a time period that is inversely related to the overcurrent. An instantaneous trip signal generator circuit produces a trip signal in response to output current between a minimum and a maximum magnitude and increasing at a rate greater than a selected rate, which conditions indicate the presence of high overcurrent in the line. A switch or gate is responsive to either trip signal to apply the output current and the stored energy to the circuit interrupter. With moderate overcurrent in the line, neither the first range of stored energy nor the output current is sufficient to operate the circuit interrupter. Accordingly, the trip signal from the time-current trip signal generator circuit first causes the energy storate circuit of the power supply to store a sufficiently greater amount of energy before operating the switch.
