Title: Optical receiver
Inventor: DREXLER REINER DIPL ING
IPC: H04B10/69
Filed: 1987-12-23
Abstract: Optical receivers are frequently constructed as transimpedance amplifiers, a photoelectric element being connected to the input of the transimpedance amplifier. In the case of input signals having a high continuous-wave light component, a coupling capacitor is in most cases provided between photodiode and input of the transimpedance amplifier, but this coupling capacitor limits the bandwidth of the optical receiver. This coupling capacitor can be omitted when the circuit arrangement presented is used. For this purpose, the transimpedance amplifier is constructed as differential amplifier and the input of the transimpedance amplifier is connected to a current source circuit which is controlled by a control signal derived from the output signal of the transimpedance amplifier. The circuit arrangement is suitable, for example, for optical receivers of optical-fibre transmission links.

Abstract: The invention relates to a method for injection moulding of pieces injected from plasticisable material, in particular from plasticisable liquid crystal polymers. The plasticised material is injected into a closed injection mould having at least two gates by in each case an assigned plasticising and injecting unit, and further material feeding compensates for any shrinkage of the cooling injection-moulded pieces which may occur. For filling the mould cavity of the closed injection mould by the one plasticising and injecting unit, the plasticised material flows via the one gate into the mould cavity and partly continues to flow via the other gate in the direction of the other plasticising and injecting unit.
Patent DE-3815766-A1 (DE)
Title: Process for producing pellets of crude phosphate
Inventor: STENDEL JOACHIM DIPL CHEM DR
IPC: C01B25/01
Filed: 1988-05-09
Abstract: In the production of pellets of crude phosphate by drying, firing and cooling of granules using two travelling grates, the granules first pass as a bed on a first travelling grate through drying, firing and hardening zones separated from one another by intermediate walls. After passing through a heat-equilibration zone located between the two travelling grates, the pellets finally reach a second travelling grate serving as cooling zone. During this procedure, the granules are predried in the drying zone by means of hot waste gases flowing downwards from above, the predried granules are largely fired to give pellets in the firing zone by means of heating gases flowing downwards from above and in the hardening zone granules which are located at the bottom and have been only predried are further heated to the temperature required for strengthening by means of a gas stream drawn through downwards from above. Finally, all of the pellets are introduced with mixing into the heat-equilibration zone and the pellets are cooled in the cooling zone by means of air flowing upwards from below, before they are finally discharged. In this procedure, the heating gases flowing downwards from above in the firing zone are at least partially generated by combustion of lignite (brown coal) dust with air above the first travelling grate.

Title: Bus with a frontal entrance door
Inventor: BILDHAEUSER HANS-PETER
IPC: B62D35/00
Filed: 1988-12-06
Abstract: For improved entry a bus can be equipped with a frontal entrance door (transversely to the direction of travel). With the aid of an air-sprung front axle the vehicle body can be lowered to such an extent that there only remains a small height to overcome, or in conjunction with an appropriately shaped bus stop a step-less entrance is offered. This makes it possible for people in wheelchairs to have access. So that the person in the wheelchair does not block the entrance region he is positioned below the driver. The raised position of the driver gives him a good view. The attachment of information boards in his foot region only slightly obstructs his field of view. The frontal entrance door makes it possible for the front end to be inclined as desired or shaped spherically without restricting the clearance width and height, which restriction often occurs in conventional side entrances. This results in an aerodynamically favourable shape which has an energy-saving effect.
