The proctologic pad, intended to receive anal discharges, is composed of a laminated web comprising at least one layer which is impermeable to liquids, but permeable to air, of at least one absorbent layer, and, on the face (2) opposite the one receiving the discharges, at least two adhesive zones (8a, 8b) which become superimposed, adhering to each other, when the pad is folded in two around a fo...

An automatic guided vehicle travels for a predetermined distance by detecting the distance covered, and thereafter stops when the mark located at the desired stopping point is detected by at least one sensor. Obstacles on the route, and cumulative error therefore have very little influence on the vehicle's travel, so that accurate travel control is obtained.

PURPOSE:To reduce the working load of an operator by performing an automatic steering operation of cars on the basis of a standard beam given from a laser oscillator so that the difference is kept within a prescribed range between a prescribed follow-up route of cars and a real route where the cars travel actually. CONSTITUTION:A laser oscillator 1 produces a standard beam for a follow-up route, a...

PURPOSE:To perform immediately the processing for abnormality of various machine instructions and increase the instruction processing capability by setting the maximum time of execution needed for each of various machine instructions and producing an error signal after detecting that the next instruction is not started even when said maximum execution time elapses. CONSTITUTION:A machine instructi...

PURPOSE:To detect the breakdown of a file in a short processing procedure by adding the same file update number at the head and the end of the information to be stored and deciding the coincidence or not of the update number between the head and the end of the information in a reading mode. CONSTITUTION:When a telegram (x) is supplied to a CPU1 from a terminal device X, the contents of file inform...

A water bed includes a water-filled bladder resting upon a base having a semi-flexible outer framework providing lateral support for the periphery of the bladder. The outer framework is divided into a lower wedge-shaped portion affixed to the base, and a movable wedge-shaped upper portion resting on the lower wedge and hinged to the base along the inside edge of the lower wedge. The periphery of t...

The present invention relates to a safety binding of a boot on a ski comprising two lateral clamps (4) movably mounted under the action of an elastic member (28) parallel to the plane of the ski (3) between a closed position in which the clamps coact with the sole of the boot and an open position. Each clamp (4) is connected to one end of a longitudinally slidable strip (45) by means of articulate...

Polymer compositions having enhanced oxygen index values as measured by ASTM Method D-2863-70 are disclosed, which compositions contain effective amounts of a bromo or chloro derivative of stilbene.

High performance (high tenacity and modulus) polyethylene fibers are subjected to pressure at elevated temperatures in the absence of a matrix to form articles such as non-woven fabrics and film-like structures, which may be translucent or even transparent. Good fiber adhesion and even fiber deformation to produce a substantially void-free article are achieved, even when molding temperatures are b...

To acquire and record the variation of a value such as a pressure as a function of a parameter such as time in a sonde (10) lowered into a well (12), pressure measurements are made at equal time intervals, these measurements are digitized and entered in a nonvolatile memory selectively so as to maximize the accuracy of the pressure variation reading during the measurement period, while minimizing ...

The invention provides an installation for testing a well by pumping by means of a submerged pump and a process for use thereof. The assembly 6 formed of an hydraulic pump and motor is carried by one end of a reinforced flexible tube 1 wound through a pulley 7 on a drum 3 actuated by the surface motor 8. . In the sheath of tube 1 are housed electric conductors 2 for supplying the motor of assembly...

A hydraulic cement mix including hydraulic cement, aggregate, sufficient water to effect hydraulic setting of the cement, and an admixture comprising one part by weight of a single compound or a mixture of two or more compounds selected from a group consisting of water-soluble salts of sulfonated melamine formalin condensates and water-soluble salts of aromatic hydrocarbon sulfonate formalin conde...

Metallic droplets in liquid, solid or partially solidified form are deposited onto a substrate to produce cast or coated articles by utilizing the Coanda Effect to draw one stream of gas toward another stream of gas flowing over a surface and introducing molten metal between the two gas streams such that the molten flow is broken into droplets. In the embodiment primary fluid flows through slit 50...

PURPOSE:To work and form exactly the end part of a pipe in a short time by crushing the end part of a pipe to be attached by butt welding to the side face of a pipe frame by a die having the shape conforming to said side face. CONSTITUTION:A pipe 3 is clamped onto a stationary plate 2 of a press machine in the case of attaching the end part of the pipe 3 by butt welding into a T shape to the side ...

The loader comprises a beam 3 articulated on a shaft 1 and capable of being lifted by a lifting jack 8. A bucket 7 is articulated at the end of the beam 3 and is connected by a connecting rod 12 to a lever 11 controlled by a bucket jack 13. The chambers of the bucket jack 13 are connected to the chambers of a compensation jack 9 so that, when the beam is lifted by the jack 8, hydraulic fluid is tr...

PURPOSE:To inspect exactly the propriety of an internal pressure and whether the internal pressure is suitable or not, irrespective of a quality of material and a structure of a tightly sealed-up vessel, by measuring a deformation quantity of the tightly sealed-up vessel, which is generated in case when an external pressure is applied to the tightly sealed-up vessel. CONSTITUTION:A pressing member...

A process is described for increasing the space time yield of polymer production in a fluidized bed reactor employing an exothermic polymerization reaction by cooling the recycle stream to below its dew point and returning the resultant two-phase fluid stream to the reactor to maintain the fluidized bed at a desired temperature above the dew point of the recycle stream.
