Abstract: Bei Koppelfeldeinheiten dieser Art, die unter Verwendung eines zyklisch eingeschriebenen und wahlfrei ausgelesenen Informationsspeichers arbeiten, ist eine Begrenzung der Anschlußzahlen insbesondere dadurch gegeben, daß beim wahlfreien Auslesen eine bestimmte Geschwindigkeit nicht überschritten werden kann. Erfindungsgemäß werden dadurch höhere Anschlußzahlen erreicht, daß die Koppelfeldeinheiten aus Bausteinen (BS1 und BS2) zusammengesetzt werden, deren gleichgeordneten Eingänge (PCMk) miteinander verbunden sind und in die jeweils je Pulsrahmen mehr PCM-Worte eingeschrieben als ausgelesen werden. Damit ist die Auslesefrequenz niedrig gehalten, wegen der eingangsseitigen Vielfachschaltung mehrerer Bausteine aber dennoch ein blockierungsfreies Durchschalten möglich.

Abstract: A diffusion washer and/or thickener assembly is provided that is greatly simplified. A number of withdrawal screens (12) and fluid introducing structures (14) are provided supported by spider arms (24) which comprise conduits (16) for introduction of liquid into and withdrawal of liquid from an elongated upright hollow vessel (10) in which the assembly is disposed. The conduits (16), with attached screens (12), are reciprocated up and down by a single linear actuator (60) located above the vessel (10) and within the cross-sectional area thereof so that the side (11) and bottom (13) walls of the vessel need not be penetrated by the conduits (16). The screens (12) and fluid introducing structures (14) remain stationary with respect to each other during reciprocation. A number of wiper blades (64), which may be operated by a single linear actuator (66), are provided at the top of the vessel (10) for moving upwardly flowing pulp into withdrawal conduits (62) surrounding the vessel periphery.

Abstract: The activity of a copper-containing catalyst used in the production of amides from nitriles by hydrolysis wherein the copper-containing catalyst serves as at least one electrode in an electrochemical reactor containing a solution including the nitrile to be hydrolysed and water is maintained by applying a direct current to the reactor at least intermittently. The copper containing electrode comprises elemental copper and the direct current may be applied to maintain the partial surface coverage at an average thickness of 0.75 to 12.5 monolayers of ionic copper. The hydrolysis of acrylonitrile to acrylamide is described.

Abstract: A level-sensitive filling device for fitting to a secondary electrical cell is formed as a plug (20) to replace the normal vent plug. The device includes inlet and outlet passages (1 and 2) respectively for connection to a water supply system and is controlled by a float (4) which, in use, is supported by the electrolyte (5) of the cell. The float (4) and the structure of the device around the openings (22 and 23) to the inlet and outlet passages are shaped to co-operate in such a way that when the correct level of electrolyte (5) is reached, the inlet and outlet passages (1 and 2) are substantially closed off from the body of the cell but not from one another. The shaping is such thatthe path offlow (6) from the inletopening (22) to the outlet opening (23) is of reduced cross section in relation to the inlet and outlet passages (1 and 2) and the resultant flow of fluid from one passage (22) to the other passage (23) thus causes a reduction of pressure outside the closure (7) formed by the float (4) in relation to the pressure in the cell, this differential pressure preventing any further flow of water into the cell, but allowing the escape of gas generated in the cell.

Abstract: A single channel duplex transmitter/receiver utilising digital FSK signals. An analogue-to-digital converter (2) frequency modulates a local oscillator (5) the output of which is coupled via a mixer/combiner/splitter network (6) to an aerial (7). FSK signals received from the aerial are mixed with the local oscillator output in network (6) to provide quadrature signals which are low-pass filtered (8, 9) before being demodulated in a zero IF demodulator (10) to give a digital output. To avoid unwanted sidetone the output of the A/D converter (2) is fed through a delay (12) to a digital network (11) where it is subtracted from the corresponding signals fed back through the demodulator (10). The digital signals are then fed to a D/A converter (13).

Abstract: An anaesthetic vaporiser of the by-pass type has a sump 7 with an outlet flow path comprising a first run 27 leading upwardly, a second run 30 leading downwardly and a third run 32 leading upwardly again. A duct 23 connects the lower end of the run 30 with the lower part of the sump and in normal operation is sealed by the sump liquid. However, if the vaporiser is displaced such that the liquid flows from the sump into runs 27 or 30 of the outlet flow path the liquidinevitably drains from the duct 23. A flow path for inflowing gas is thereby opened directr ly to the downstream end of the run 30, preventing the over-administration of vapour from the device and removing any danger of liquid anaesthetic being blown through the device from the runs 27 and 30.

Abstract: The signal-quality monitor has a filter (7) connected to the output of the FM demodulator (4). The filter has a relatively narrow bandwidth above the stereo-multiplexed signal inside the IF band. The filter's output is passed to an integrator whose own output is connected to the input of a level comparator (10). The comparator's output is coupled to a control (2) that tunes the receiver or performs other functions. The FM demodulator's output also passes via a bandpass filter (11) and a rectifier (12) to give a dc control signal that operates a switch (8) between the output of the first filter (7) and the rectifier (9) at the comparator's input. The switch acts as a gate and is only active when an LF signal is present. It opens when noise is excessive.

Abstract: A fabric mounting track consisting of two parts, a back support plate (11) and a hinge lock plate (10). The hinge lock plate (10) has a straight portion (15) at one end and a substantially circular portion (12) at the other end forming a hinge. The hinge is disposed in a plane spaced from the straight portion (15). The back support plate (11) also has a substantially circular portion (22) at one end forming a larger hinge into which the smaller hinge of the hinge lock plate (10) fits. Extending from the straight portion (24) of the back support plate (11) at an acute angle is a ledge (26), while the other end (30) terminates in a straight portion forming a small angle, and which may have its free end extending in the opposite direction. The hinge lock plate (10) is provided with substantially equally spaced lancings (16, 17) punched out from the straight portion (15) of the hinge plate (10). At intervals between a number of lancings, one (12) of the lancings is larger in size. It will pierce the fabric (32) to support it while the back support plate (11) is hanging down from the hinge lock plate (10). Thereupon the hinge lock plate (10) is rotated at 180' so that the large size lancings (17) will hook behind the ledge (26), while the small size lancings (16) will impact the free end'(27) of the ledge (26), thereby forcing the fabric (32) through the lancings (16). The lancings are now supporting the fabric.

Abstract: A method for measuring a low-frequency signal progression at a measuring point of a specimen by use of an electron probe. A load on the circuit is kept as low as possible by employing a pulsed electron probe during a search of the measuring points. The pulsed electron probe may also be employed for actual measurement. By providing a pulse repitition frequency of the electron probe which is independant of the operating frequency of the circuit specimen, a phase shift of the primary electron pulses relative to the low-frequency signal progression is not necessary for real time measurement of the low-frequency signal progression.
