Title: Biasing control for compound semiconductors
Inventor: DUFF CHRISTOPHER IAIN
IPC: G05F3/24
Filed: 2023-06-16
Abstract: A compound semiconductor integrated circuit is disclosed, which includes biasing circuity for generating a bias voltage at a bias output node. The biasing circuitry comprises a first circuit branch configured to extend between a defined voltage and a supply voltage. The first circuit branch includes a first transistor configured as a current source to generate a defined current in the first circuit branch and a controllably variable resistance. The bias output node is coupled to the first circuit branch at a first node which is between the controllably variable resistance and the first transistor. The biasing circuitry is operable so that the resistance value of the controllably variable resistance varies with a control voltage so as to vary the value of the bias voltage.

Abstract: The invention provide compounds having the formula:
     in which R, is iso-propyl orsec-butyl; R 2  is methoxy, hydroxy or loweralkanoyloxy; and R 3  is hydrogen; lower alkanoyl; α-L-oleandrosyl; 4'-(lower alkanoyl)-a-L- oleandrosyl; 4'-(α-L- oleandrosyl)-α-L-oleandrosyl or 4"-(lower alkanoyl)-4'- (α-L- oleandrosyl)-α-L- oleandrosyl. These compounds are derivatives of C-076 and are produced by catalytic reduction of the 22,23-position of the C-076 molecule. Further reaction of the reduced C-076 compouds is also possible. The compounds thus produced are used for their profound anthelmintic, insecticidal, ectoparasiticidal and acaracidal activity. Compositions containing the described C-076 derivatives as active ingredient are also disclosed.

Abstract: A method for the gasification of large-sized vegetable materials using a fixed bed gasogene. This gasification method includes the steps of moving the materials in a fixed treatment chamber extending substantially horizontally and having opposite rear and forward ends, the materials being moved from the rear end towards the forward end through substantially the whole transverse section of the chamber and being successfully subjected to drying, pyrolysis and gasification in successive areas of the chamber. Hot gases are generated by combustion in a zone free of materials to be treated and located in the chamber in front of the natural talus created by the front of the whole bulk of materials which occupy substantially the whole transverse section of the chamber. Gases are extracted from the chamber and recycled into the zone in front of the natural talus, whereby tar produced from the pyrolysis and carried away by the extracted gases is eliminated by heating the recycled gases in the zone. The temperature of the extracted gases is at least 500 DEG  C. after having passed through the materials contained in the chamber. The gas having passed through the material in the gasification area is taken out from the chamber at a location in front of the pyrolysis area product, whereby the product gas is freed from tars.

Title: Procede de travail pour la fabrication d'un rotor a poles lamelles d'une machine electrique
Inventor: HUPACH HEINZ
IPC: H02K15/02
Filed: 1980-07-14
Abstract: Dans les machines electriques de grand diametre, notamment les machines de centrales hydrauliques, les rotors sont constitues par des segments (1) formes de plusieurs toles empilees avec recouvrement et montes sur un croisillon rotorique (6). En raison du decalage des segments de tole lors de l'empilage pour former des anneaux de plusieurs metres de diametre, il se produit des imprecisions dues a l'addition des tolerances de division des toles individuelles et que l'on appelle decalage d empilage. De ce fait, les trous (3) de passage des boulons sont retrecis de l'ordre de grandeur de centiemes de millimetre. Pour retablir la dimension de passage des trous, il est propose de redonner une mesure exacte aux percages (3) pratiques dans les segments de tole (1) empiles en ecrasant leur paroi a l'aide d'un outil de calibrage comprenant un corps cylindrique (12) muni a sa peripherie de rouleaux coniques (14). On evite ainsi la formation de copeaux et la puissance de la machine-outil est nettement inferieure a celle des machines utilisees dans les procedes connus. De plus, 1e calibrage des trous peut etre effectue en une seule passe, ce qui entraine aussi une economie de temps e travail importante.

Abstract: Die Erfindung bezieht sich auf eine Transistorgegentaktendstufe, insbesondere für Impulsformer mit Gegenkopplung vom Ausgang auf den Eingang sowie hochohmigen Eingang und niederohmigen Ausgang. Bei der Prüfung von Baugruppen der Datentechnik sollen Kurzschlüsse in der Baugruppe nicht zur Zerstörung der Endstufe der Prüfeinrichtung führen. Die Erfindung sieht hierzu vor, daß in jeder Gegentaktstufe als Eingangstransistor ein Feldeffekttransistor (T31, T37) verwendet wird, der jeweils über eine Emitterfolgerstufe (T32, T74) die Parallelschaltung mehrerer Ausgangstransistoren (THA, TBA) ansteuert. Die Basen der Ausgangstransistoren (THA, TBA) werden über eine Konstantstromquelle (KH, KB) angesteuert, die bei Überspannung am Ausgang abgeschaltet wird. Die Transistoren in den beiden Gegentaktstufen sind zueinander komplementär. Zudem sind Mittel (OP4, T35, OP11, T80) zur Stromversorgung vorgesehen, die abhängig vom Spannungshub und der Impulsgrundspannung des Signals gesteuert werden. Die erfindungsgemäße Transistorgegentaktendstufe ist insbesondere als Endstufe für einen Impulsformer im Prüfautomaten für Datenverarbeitungsgeräte geeignet.

Abstract: Problems have occurred using chitin derivatives having surface ionic groups as ion-exchangers. These problems can be overcome by employing a material produced by acylating or treating with an acid the surface of a material composed of a cross-lined ionic chitin derivative. The acylation or acid treatment eliminates the surface ionic groups, for example by converting them to non-ionic groups. The resulting material can also be employed in dialysis and in the separation and purification of glycoproteins.

Abstract: A method of testing the integrity of the internal lining of a hollow body, especially a pipeline, by transmitting an ultrasonic wave from the exterior of the body through the adjacent wall of the body and monitoring the wave, if any, reflected from the opposite wall. In many cases, especially concrete linings, an intact or partially intact lining on the adjacent wall will absorb the ultrasonic wave and there is no reflected wave. A reflected wave frequently indicates loss of the lining on the adjacent wall although in some cases depending on, for example, the thickness of the lining or the material of which it is made, a reflected wave may be obtained even when the lining is intact. In such cases comparison of the reflected wave with predetermined standards provides an indication of whether or not the lining is intact.
