A method and apparatus for fault diagnosis in pulse controlled devices whose control contains a logical network and a memory composed of a plurality of registers through the utilization of a data processing device wherein test apparatus is connected to the data processing device, the tested device internal timing pulse is switched off and replaced by a processing pulse supplied by the data processing device to form the basis on which the logical network of the test apparatus carries out a proces...

A differential amplifier is connected at one output terminal to the input terminal of a current mirror and at its other output terminal to the second terminal of the current mirror and to a load in shunt with the current mirror. In response to one polarity of an input signal applied to the amplifier, the current mirror saturates receiving substantially all of the amplifier current. In response to another polarity of the input signal, the current mirror operates in a linear mode receiving a porti...

A computer including a control unit, an arithmetic-logic unit, an input unit, an output unit, a memory unit, and circuitry interconnecting the units for transmitting, processing and storing sequences of characters, the memory unit is constituted by a plurality of stack registers each having a large storage capacity for storing expressions in the form of strings of characters, and the control unit constitutes a reduction processor operatively associated with the stack registers for determining th...

A haemodialyzer for use in a haemodialysis equipment of partial recirculation type, in which a vast plurality of semi-permeable hollow fibers formed in a bundle are diagonally disposed in a housing with surplus in length so that the ends of the bundle may direct oppositely downward and upward, respectively, and a dialyzate intake and exit are provided in such positions that flow of the dialyzate may effectively traverse the bundle of hollow fibers. With this haemodialyzer, the bundle of the holl...

A feedblock fashioned from a plurality of plates is disclosed which distributes two flows of dissimilar synthetic resinous materials into a radially stratified annular form for extrusion by a pipehead die. The feedblock is mounted on a pipehead with the plurality of plates defining material flow channels for three strata. Independently operable valves vary stratum thickness and assure radially matched flow conditions between strata at confluence. Each stratum is independently accelerated through...

Improved methods of employing TRH to enhance lactation and to prolong postpartum infertility are disclosed. The methods may be employed with women following full term delivery, as well as in cases of premature birth. In addition, a method for the use of TRH in surrogate mothers is disclosed.

Data demodulator which demodulates a received signal by means of comparing the received signal with itself delayed to produce a comparison signal having one amplitude value upon identity and another different amplitude value upon non-identity. The comparison is performed by a modulo two net-work herein illustrated as an EXCLUSIVE OR gate. The comparison signal is filtered by a digital filter which includes an UP/DOWN counter and associated control circuitry. The output of the digital filter is s...

Process of separating nutritional components from soybeans or other oilseeds, employing enzymatic hydrolysis of protein. Clean, whole soybeans are comminuted, heated at about 90.degree.-140.degree. C., and then cooled by adding more water. A proteolytic enzyme, preferably derived from an Aspergillus or Bacillus sp., is added to the slurry, which is then maintained at an incubation temperature of 25.degree.-75.degree. C. until the protein is sufficiently hydrolyzed. The fibrous solids portion is ...

A moisture setting printing process comprising the steps of printing with an ink having a vehicle comprising a glycolic soluble resin such as an acidic resin, a cross-linking agent such as hexamethylolmethyl melamine, a Lewis acid catalyst and a glycol solvent, contacting the printed ink with moisture and allowing a hardening reaction to proceed to completion.

A workpiece is cut by causing a focused spot from a laser beam to travel over its surface and a suction chamber is located on the other side of the workpiece with an opening under the cutting location so that air or other gas is drawn through the cut into the suction chamber, taking with it fumes and products of distillation. The opening in the suction chamber may be a grid supporting the workpiece. For metal workpieces a gas having an exothermic reaction with the metal can be drawn through the ...
