Abstract: The invention concerns the extrusion of helical internal gears and helical gears by pushing materials (5) processed to any type of blank into a die unit (2,3) successively by means of a punch (17), i.e., by passing the materials (5) once through the die unit (2,3). This die unit (2,3) comprises an outer contour restraining container (2) into which metal materials (5) each having a central bore are to be inserted, a die (3) placed contiguously below the container, these container (2) and die (3) being arranged to be circumferentially rotatable relative to each other, and upper and lower mandrels (13,16) disposed inside the container (2) and the die (3) in alignment with their axes, respectively, and interconnected for being circumferentially rotatable relative to each other. The metal materials (5) being successively pushed into gaps between the upper mandrel (13) and the container (2) and between the lower mandrel (16) and the die (3) by means of a punch (17) to mold helical internal gears (21). The outer peripheral surface of the lower mandrel (16) has formed therein an approach area (161a) in which the peripheral surface is gradually varied into a teeth shape of helical internal gear and a product configuration area (161b) continuously extended from the approach area and having a complete teeth shape of the helical internal gear (21).

Abstract: A pump control system is described in which the pumping mechanism causes corresponding movement of a pair of capacitor plates  (64, 66). The plates are energized by an a.c. signal, and the signal produced by the plates is amplitude detected, with the amplitude modulation representing pumping force. The pumping force is converted to pumping pressure. The pumping pressure peak during pumping and the pressure minimum during filling are detected to determine the portion of a pumping cycle required to make the transition between these two pressure levels. The difference between the two pressure levels divided by the transition portion of the pumping cycle gives a measure of the compliance of the pump chamber. The ratio of the compliance measure to the total cycle, when multiplied by the nominal chamber volume, gives a measure of unpumped volume, which is subtracted from the nominal volume to give the volume actually pumped during a pump cycle. The volume pumped is compared with a desired flow rate to determine a speed control value for the motor of the pumping mechanism. A motor control signal is developed by subtracting from a constant number a value which is a factor of the speed control value and the position of the motor.

Abstract: A car bumper is assembled by welding together a channel-shaped facing component (4) and a rigid backing component (15), of mutually compatible thermoplastics, using sacrificial heating elements (17) to soften the surface portions to be welded while the components are held in jigs. Once these portions have been softened, but not until then, pressure is applied to force the softened portions together, by means of movable members (9,10) coextensive with the seams and moved by inflation of resilient tubes (11,12) carried in recesses in the jig (5) which supports the facing component. After the weld surfaces have thus become fused, they are allowed to cool.

Abstract: Water absorbent structures are disclosed which are intended for use as wound dressings, disposable nappies (diapers) or similar applications. The structures comprise a flexible porous substrate, e.g. an open-cell foam web which is impregnated with (a) a solid, water-­insoluble water absorber which has a fine particle size and is capable of absorbing at least 30 times it weight of water and (b) a hydrophilic binder which retains the water absorber in the substrate and comprises a substantially non-cross-linked, water-insoluble, hydrogel forming polymer. 
     Component (a) has a high affinity for water due to the presence of hydrophilic groups in the polymer, but is insoluble in water and in common organic solvents. Component(b) is also water-insoluble, but because of its non-cross-linked structure is soluble in common organic solvents, such as ethanol.

Abstract: In a system for recognizing a time sequence of feature vectors of a speech signal representative of an unknown utterance as one of a plurality of reference patterns, a generator (11) for generating the reference patterns has a converter (15) for converting a plurality of time sequences of feature vectors of an input pattern of a speech signal with variances to a plurality of time sequences of feature codes with reference to code vectors (14) which are previously prepared by the known clustering. A first pattern former (16) generates a state transition probability distribution and an occurrence probability distribution of feature codes for each state in a state transition network. A function generator (17) calculates parameters of continuous Gaussian density function from the code vectors and the occurrence probability distribution to produce the continuous Gaussian density function approximating the occurrence probability distribution. A second pattern former (18) produces a reference pattern defined by the state transition probability distribution and the continuous Gaussian density function. For a plurality of different training words, a plurality of reference patterns are generated and are memorized in the reference pattern generator.
