Patent EP-0251032-A3 (EP)
Title: Packing or unpacking machine
IPC: B65B21/18
Filed: 1987-06-16
Abstract: A packing or unpacking machine having conveyor tracks for articles and containers, with transfer units that are guided in a circular path above these conveyer tracks. Each of the transfer units has a pick-up and carrier head on a support element that can be raised and lowered. A movement mechanism is provided for generating a relative movement for the pick-up and carrier heads relative to the support elements, with this relative movement being superimposed over the rotational movement of the support elements, so that during respective rotation of the support elements, which follow the circular path, the pick-up and carrier heads are moved in a common elliptical or elliptical-like overall path of revolution. In so doing, the respective pick-up and carrier heads are moved about a vertical axis such that a constant parallel position is maintained relative to the conveyer tracks. In this way, not only are the pick-up and carrier heads moved in the transport direction of the conveyer tracks for a period of time that is sufficient to permit reliable pick-up or depositing of the articles, but also a smooth, quiet rotation of the pick-up and carrier heads in the overall path of revolution is achieved.

IPC: A61P1/04
Filed: 1988-02-01
Abstract: Known processes for preparing cholestyramine 
involve chloromethylating and aminating 
unfunctionalized styrene/divinylbenzene beads in the 
presence of added halogenated hydrocarbon swelling 
solvent, typically ethylene dichloride. The use of such 
halogenated swelling solvent is disadvantageous because 
of toxicological implications.  
     The present invention provides a process for 
preparing cholestyramine by chloromethylating and 
aminating unfunctionalized styrene/divinylbenzene 
copolymer beads, the chloromethylation and amination 
being conducted in the absence of added halogenated 
hydrocarbon swelling sovent.  
     Furthermore, the cholestyramine produced by the 
process of the invention has improved palatability when 
compared with cholestyramine produced by known 
processes.

Title: A fluid spring
IPC: F16F9/43
Filed: 1989-06-22
Abstract: According to an illustrative example a gas spring 
comprises a cylinder (10) and a piston rod (11) axially movable 
with respect to the cylinder. The piston rod is guided 
through a guiding and sealing ring (13) adjacent one end of 
the cylinder. A piston (12) is fastened within the cylinder 
with the inner end of the piston rod. The piston is 
provided with an axial passage (20) connecting the two 
working chambers on both sides of the piston. A 
pressurized gas is provided within both working 
chambers. One of the working chambers is connected 
with a pressure reservoir (2). The pressure of gas within 
the pressure reservoir is larger than the pressure 
within the working chambers. A shut-off valve (5) is pro­
vided between the pressure reservoir and the respective 
working chamber. This shut-off valve is automatically 
controlled such as to admit pressurized gas from the 
reservoir to the respective chamber when the pressure 
value within the respective working chamber falls below 
a predetermined pressure value. The shut-off valve is 
closed again when the pressure within the respective 
 
 
working chamber has risen again up to a determined 
pressure value. Such it is warranted that the pressure 
within the working chambers does not fall below the 
predetermined value as long as the increased pressure 
within the reservoir exists.

Title: Optical transmitting and/or receiving element
IPC: H04B10/27
Filed: 1989-09-16
Abstract: An optical module is used for communication over optical waveguides. To couples laser light to or from the optical waveguide (3) with as little loss as possible, the laser diode (2) must be precisely aligned with respect to the core region (22) of the end face (14) of the optical waveguide. In conventional modules, this requires costly and complicated mechanical couplers, which nevertheless do not have the necessary long-term stability. To solve the problem of how to provide a low-cost laser-to-fiber coupling which exhibits long-term stability, the optical module (1) is provided with a control facility (16, 17, 18) which controls the coupling of light on the basis of measurements of the differences in reflection factor between the core region (22) and the cladding region (23) of the end face of the optical waveguide (3). For this measurement and control, use can be made of low-priced components employed in CD players.
