Abstract: Abstract A liquid component can be introduced into a detergent bar by injecting liquid within or immediately downstream of a multi-apertured plate positioned before the compression cone of an extruder.   The method can be used to produce marbled bars with the aid of a coloured liquid and is described in UK 1387567.         When a double extruder is used together with a common compression cone the injected liquid becomes unevenly distributed within the detergent.   Even distribution of the liquid as striations is achieved by use of a partition in the cone to ensure each detergent stream is subjected to separate compression during movement down the cone.

Abstract: ABSTRACT OF THE DISCLOSURE            A negative impedance repeater for amplification in telephone lines operating at voice frequency comprises two converters, one of them stable with open terminals and the other stable with short-circuited terminals; each converter is loaded by a fixed network of passive impedances chosen according to the characteristic impedance of the line to be amplified, and provided with means, external to the network of passive impedances, for adjusting the feedback, and consequently the conversion ratio.          The conversion ratios of the two converters may be varied independently from each other so that in the case of loaded lines their product may be kept always constant and this allows to adjust the repeater gain without modifying its impedance, while for unloaded lines it is possible to obtain that such product increases with a certain law by increasing gain, and this fact causes an equalization at the highest frequencies of the band, which is necessary for this type of lines.

Abstract: O.Z. 32,091 ABSTRACT OF THE DISCLOSURE:          The invention relates to a process for rapidly letting-down the pressure in continuous high pressure polymerization systems for the polymerization of ethylene. In this process, the let-down hot reac-tion mixture is passed into an expansion vessel in such a way that the jet of let-down hot reaction mixture issuing from the let-down line is led into the partially water-filled expansion vessel at an angle of from 0 to 45° to the water surface, so that the jet does not enter below the surface but must touch or strike it.   The method described makes it possible to let the mixture down partially and thus to slow down the decomposition in the case of explosive decomposition reactions occurring in the polymerization system.

Abstract: APPARATUS AND METHOD AND MEANS FOR REMOVING SURFACE DEFECTS FROM A WORKPIECE     ABSTRACT OF THE DISCLOSURE     Apparatus and a method for use thereof to remove surface defects from a formed workpiece having a rotary axis about which the workpiece is designed to rotate.  A plurality of rotary tools, preferably three, of the apparatus are rotatably mounted in spaced relationship to each other to receive the workpiece there-between in engagement therewith during rotation of the tools and the workpiece.  Pressure applied to each of the tools independent-ly of each other tool maintains an engaged condition between the tool and the workpiece while allowing outward tool movement upon engagement with a surface defect such that the rotary workpiece axis remains at a fixed location.  Extendable and retractable hydraulic cylinders are preferably utilized to apply the pressure between the tools and the workpiece and the engagement therebe-tween is at intermeshed teeth thereof so as to remove surface de-fects from the workpiece teeth.  Each cylinder includes a bore and an undersized piston received within the bore.  Hydraulic fluid supplied to the cylinders applies pressure between the tools and the workpiece while the fluid leaks past the pistons at a predetermined rate and, upon engagement of a tool with a sur-face defect on the workpiece, an increased rate of leakage flow permits cylinder retraction that allows outward tool movement without movement of the workpiece.  A power drive mechanism of the apparatus rotates one of the tools with a synchronizer rotat-ing the other tools prior to meshing engagement of the workpiece with the tools.  After a movable carriage of a carrier moves the workpiece into meshing engagement with the tools, the workpiece synchronizes the rotation of the tools with each other.  The drive mechanism increases the rate of rotation after the tools are meshed with the workpiece and rotates the tools in opposite direc-tions to apply pressure that removes surface defects from both sides of the workpiece teeth.

Abstract: DIGITAL DIFFERENTIAL PRESSURE       MEASUREMENT APPARATUS            Abstract of the Disclosure Apparatus for measuring a pressure differential in a fluid carrying conduit characterized by a digital representation of the rate of fluid flow and a high degree of accuracy is disclosed.  The sensor portion of the apparatus includes two identical electrically driven piezoelectric crystals.  One crystal provides a series of pulses at its resonant frequency for use as a reference signal.  The second crystal provides a series of pulses at a frequency which is inversely related to a force applied thereto. The sensor further includes two (minimally) arcuately curved stainless steel sealing diaphragms urged in opposing directions by two pressures acting in opposing directions. The movement of the two diaphragms, which are rigidly connected to one another, and which is directly related to the difference in magnitude of the two pressures, is used to apply the force to the second crystal.  The pulse trains provided by the first and second crystals are transmitted to a modulator which provides, as its output, a series of pulses at a frequency which is equal to the difference of the frequencies provided by the first and second crystals, this last frequency, which is subsequently provided to utilization apparatus, therefore being directly related to the difference between the first and second pressures.         This abstract is not to be taken either as a complete exposition or as a limitation of the present invention, however, the full nature and extent of the invention being discernible only by reference to and from the entire disclosure.

Abstract: ABSTRACT OF THE DISCLOSURE:             Permanent moulds for casting, supported by carriers proceed along a closed track comprising a forward strand and a return strand, maintaining thereby their original orientation.         The carriers with moulds are advanced along the forward strand step by step with most operations performed thereby, at the end of the forward strand they are shifted sidewards to the return strand where they are driven by a continuous drive toward the end of the return strand, to be at this place again shifted side-wards to the start of the forward strand. By changing the number of carriers in the return the conditions for cooling the moulds are altered and thus castings of different size enabled without changing the fundamental cycle of the arrangement.

Abstract: ABSTRACT OF THE DISCLOSURE            A method and sense latch circuit are described for determining the memory retention characteristics of differen-tially sensed metal nitride oxide semiconductor field effect transistor (MNOS FET) memory cells and arrays made up of such cells.  The method involves substitution of one differential comparator input with a known reference voltage (VR) for de-termining the analog voltage threshold levels of the memory cells.           The sense latch circuit, which can be fabricated as an integrated circuit, is responsively coupled to control inputs so that it can be operated in either a read or memory retention interrogation mode.  The determination of the analog threshold levels of each cell of an array at given times permits the determination of the array's memory window (i.e., memory retention characteristics).
