Title: Apparatus for reading and writing an optically readable information structure
Inventor: OPHEIJO WILLEM G
IPC: G11B7/09
Filed: 1981-10-08
Granted: 1990-01-31
Abstract: A light beam from a laser is focussed into a read spot by an objective lens onto optically recorded information on a drive.  A reflector rocks about an axis when driven by a drive system and a polarised beam divides and quarter wave blade enables the reflected beam modulated by the information to be separated from the transmitted laser beam.  Photodiodes determine the spot intensity w.r.t. the centre of the recorded track and a substraction circuit provides a tracking signal.  This is applied to the reflector drive system via an amplifier in order to null the tracking signal by movement of the reflector.

Title: Opto-electronic apparatus for writing and/or reading recording tracks by means of a radiation beam
Inventor: VAN ROSMALEN GERAAD EDUARD
IPC: G11B7/08
Filed: 1982-07-08
Granted: 1988-12-20
Abstract: The device measures the position of an objective holder with respect to the frame and controls electromagnetic levitation system to eliminate error.  As the holder is centred correctly the refracting edge of the prime is parrell to the Z-axis and photo detectors receive equally intense radiation beams.  If not, positioned error signals are provided for sin degrees of freedom of the objectives. In response to these signals the appropriate ones of actuator coils are energised.  Z-axis motion is achieved by an actuator coil and permanent magnet.  Movements of the objective holder are counteracted by electromagnetic bearings.  Consequently the holder is supported on its frame by electromagnetic actuator forces and electromagnetic levitation forces.

Title: Heat exchanger
Inventor: KLAREN DICK G
IPC: B01J8/24
Filed: 1984-07-21
Granted: 1991-04-03
Abstract: This invention relates to apparatus for carrying out physical and/or chemical processes, more specifically a heat exchanger (10) of the continuous type, comprising a large number of vertical heat exchanger tubes (18) mounted between a lower chamber (17) and an upper chamber (16) within a jacket (15). Within the tubes (18) small solid particles are kept in a fluidized condition by the fluid medium passing up from the lower chamber (17) through the tubes (18), so as to achieve a good heat transfer, whereas also any deposit will be removed from the innertube walls. Forthe downward flow of the granular mass at least one return tube (21) is provided. Downward circulation of the fluid medium through the return tube (21) should be minimal, however, which can be achieved by an increase of the pressure difference between the upper and lower chamber (16; 17), which increase of the pressure difference can be achieved by fitting several distribution plates (24; 42) at a level above the return tube (21) outlet into the lower chamber (17), preferably so thatthe apertures in the various distribution plates (24; 42) of the multiple design are not vertically in line.The second distribution plate (42) also serves to minimise excessive wear of the material of the jacket (15) due to the eddying motion of the granules.

Abstract: 다수의 광화이바로 이루어진 대규모 광선로의 감시시스템 등에 사용되고, 광선로를 전환하는 광스위치장치, 광스위치장치는 제1의 광스위치 수단과 제2의 광스위치 수단을 구비하고 있다. 제1의 광스위치 수단은, 일선의, 제1의 광화이바의 일단면을, n선의, 제2의 광화이바의 각 일단면에 선택적이고, 광학적으로 전환·접속한다. 제2의 광스위치 수단은, 각 일단면이 제2의 광화이바의 각 타단면에 광학적으로 접속되고, n선으로 이루어진 제3의 광화이바의 타단면의 전체를, 실질적으로 n선의 제4의 광화이바로 이루어진 복수의 광화이바 묶음중 필요한 하나의, 제4의 광화이바의 각 일단면에, 실질적으로 동시에 광학적으로 전환·접속한다.
