Patent DE-4327308-A1 (DE)
Title: Process and apparatus for preparing polycrystalline silicon
Inventor: KIM HEE YOUNG
IPC: B01J8/42
Filed: 1993-08-13
Abstract: In the process or the apparatus for depositing high-purity silicon on silicon particles, there is provided a moving-bed reactor which is divided into a heating zone and a reaction zone by means of a separation device. The silicon particles in the heating zone are fluidised by a carrier gas, for example hydrogen, and heated by means of microwaves. On the other hand, the reaction zone provided for the deposition of silicon, through which reaction zone the reaction gases including the silicon source flow, is heated by particle mixing occurring between the reaction zone and the upper region of the heating zone. The desired reaction temperature in the reaction zone can thus be kept stable without disrupting the microwave heating in the heating zone.

Title: Arrangement for determining the driving (running) speed of a vehicle
Inventor: HECK JUERGEN
IPC: G01P3/80
Filed: 1993-08-24
Abstract: An arrangement for determining the driving speed of a vehicle with as little noise as possible is specified which has at least two vehicle axes over a driving plane. In the arrangement, provision is made of an acceleration sensor (5) which is arranged between the vehicle axes and is essentially sensitive to acceleration components perpendicular to the driving plane. A correlation signal is formed from the undelayed output signal of the acceleration sensor (5) and a delayed signal of the acceleration sensor (5) which is generated by means of a variable time-delay device. A determination is made of the delay time for which the correlation signal reaches its maximum. The driving speed v of the vehicle is determined from this delay time t0 and the wheelbase d of the vehicle in accordance with the equation v = d/t0. <IMAGE>

Filed: 1994-01-31
Abstract: Process and apparatus for producing an endless chain (K) of mouldings (5) from plastic connected to one another in a belt-like manner by means of an injection unit and a mould-clamping unit, the endless chain (K) being made up of segments. Movable mouldings (12) can be introduced one after the other by means of a transporting system into a mould frame, two mouldings (12) being received in each case next to each other and in an exactly defined position. In a prefabricating station (A), in each case a segment is moulded by injecting plastic and at the same time is connected to a further, already premoulded segment such that they overlap, the premoulded segment being fixed in a connecting station (B). For transferring the mouldings (12), the mould-clamping unit is briefly opened. This makes it possible to produce endless chains which make do without any special mechanical connecting elements and exhibit homogeneous behaviour throughout. <IMAGE>
