Abstract: Использование: изготовление центробежным формованием трубчатых изделий из композиционных полимерных материалов, в частности электроизоляционных покрышек, используемых в электротехнической промышленности. Сущность изобретения: в установке, которая содержит форму в виде тела вращения, привод вращения формы, трубопровод для подачи формуемого материала и смесительную головку, смешивание компонентов пластмассы производится непосредственно перед подачей их в форму. Смешивание выполняется на участке трубопровода, выполненного в виде двух коаксиально размещенных труб, проходящих через центр формы. Для повышения эффективности смешивания выходное отверстие внутренней трубы выполнено перпендикулярно к ее оси, а в отверстии наружной трубы размещена смесительная головка, которая выполнена по крайней мере в виде двух крыльчаток. Ось одной из крыльчаток связана с фланцем формы посредством планки и поэтому вращается с той же частотой, что и форма. Узел вращения второй крыльчатки выполнен в виде трех сопряженных зубчатых колес. Одно из зубчатых колес - ведущее, имеет внутреннее зацепление и закреплено на форме. Ведомое зубчатое колесо размещено соосно с трубопроводом и имеет центральное отверстие, в котором закреплена вторая крыльчатка.

Title: Steering angle sensor for motor vehicle
Inventor: WIGGENHAGEN FRANK
IPC: B62D15/02
Filed: 1995-03-10
Granted: 1996-08-01
Abstract: The sensor has a steering angle sensor element (3) with which the angular position of a steering wheel is detected wrt. a full rotation. A counting unit (4) counts the number of steering wheel null transitions. An initialising arrangement (6) contains a comparator which sets an actual steering wheel signal from a sensor in relation to a reference value. A setting device initialises the counter if the compared signals coincide. The initialising arrangement contains a detector which derives the running position of the drive wheels, which are affected by the steering wheel, from representative dynamic parameters detected by the sensor elements. A corresp. signal is used to form the comparator's reference value.
