Title: Optical waveguide connector
Inventor: FINZEL LOTHAR DIPL ING
IPC: G02B6/38
Filed: 1988-03-15
Abstract: When producing the connection between two optical waveguides, it is important that the optical waveguides are aligned, with their end face sides, in a precisely concentric manner and so as to be flush with one another. For this purpose, the optical waveguides to be coupled can be inserted into a continuous groove (25) inside a holder (1). The holder (1) can consist of two parts (5, 6) between which the optical waveguides are secured inside the groove (25). The object consists in creating an optical waveguide connector in which the optical waveguides to be connected are secured, in a manner such that they can be released, by means of spring force, whereby it should be possible for the optical waveguide connection to be assembled on the spot without relatively large outlay. The object is achieved in that the holder (1) has essentially the form of a parallelepiped in which at least two edges (2, 3), parallel to the optical waveguides inserted, are bevelled at least over a part of the length of the parallelepiped, and in that the holder is totally or almost totally gripped, in the regions in which the edges (2, 3) of the holder (1) are bevelled, by a resilient bracket (4) or a plurality of resilient brackets. The resilient brackets can be easily released so that, when the connection is assembled, the optical waveguides can be inserted without any problems. The optical waveguide connector described is, above all, intended to be used on the spot, where no complexes devices for preparing the optical waveguide ends ... Original abstract incomplete. <IMAGE>

Title: Process for providing the gases required for operating high-temperature fuel cells
Inventor: KREUTER WALTER DR ING
IPC: H01M8/0662
Filed: 1988-03-25
Abstract: A process is proposed for providing the reaction gases H2 and CO2, by means of a fired reformer, for high-temperature fuel cells containing an oxygen ion-conducting electrolyte. The CO2 required for transporting the oxygen through the electrolyte comes from the off-gas of the reformer heated under atmospheric pressure, CO2 isolated by means of CO2 scrubbing being supplied to the fuel cell. The supply can be controlled via the CO2 consumption of the fuel cell.
Patent DE-3826859-A1 (DE)
Title: Packaging machine
Inventor: TAKAMURA YOSHIYUKI
IPC: B65B11/54
Filed: 1988-08-08
Abstract: The invention relates to a packaging machine for the packaging of a cubic or cuboid product with a wrapping. The machine has a wrapping-feed device which contains wrappings of different sizes and which selectively guides one of the wrappings to a packaging station, and furthermore a sensor which detects the sizes of the wrappings and which transmits corresponding signals to a control device coupled to the wrapping-feed device. The control device has an indicator device and determines whether the sizes of the wrappings come within useable range. If this is so, the wrapping-feed device is actuated in order to guide a wrapping to the packaging station. If none of the wrappings is of the necessary size, the necessary size is indicated on the indicator device. A wrapping-folding device folds the wrapping around the article to be packaged, whereupon the border of the wrapping is closed on the underside of the article by means of band.

Filed: 1988-08-20
Abstract: A remote control transmitter (3), which can be switched at a push button (4) and is held in the hand (2) of a user, of the remote control of an electric apparatus (1) generates radiation fields (5, 6) of differently identified carrier waves (7, 8) of different direction. The received field strength of the carrier waves (7, 8) received at a receiving element (14) of the remote control device are measured and from these control signals are formed in a direction detector which identify the angular deviation (Alpha) of the pointer direction (9) of the remote control transmitter (3) from a direction (13) on an optically visible marking element (12) and by this means call up operating commands for controlling the electrical apparatus (1) from a command memory via a command selector. In this manner, an electrical apparatus can be remotely controlled with great variety of operations by means of certain rotational movements of a remote control transmitter directed towards the electrical apparatus from the wrist without observation of the remote control transmitter exclusively by observing the remote-controllable electrical apparatus or a display (11) of this apparatus. <IMAGE>

Title: Blow-moulded three-handled canister together with a device and method for the production thereof
Inventor: SCHIEMANN WOLFRAM DR
IPC: B65D25/28
Filed: 1988-11-05
Abstract: In the case of a canister blow-moulded from plastic and having three handles, the upper part is formed with the handles of two injection-moulded part shells which are symmetrical with respect to the central separating plane of the canister. A part shell 22 of this kind has an outer handle 24 and half 27 of the central handle. The part shells are inserted into the halves of the blowing mould before the extruded flexible-tube material is introduced. After the mould has been closed and the flexible tube inflated to form the canister a wall made of blow-moulded plastic rests on the inside against the part shells and also the cavity between the halves 27 of the central handle is filled with this plastic. The canister thus has three very stable handles which lie well in the hand. Particularly suitable for 20 and 30 litre canisters. <IMAGE>

Patent DE-3911638-A1 (DE)
Inventor: GOTTFRIED JOSEF DIPL ING
IPC: F16K37/00
Filed: 1989-04-10
Abstract: 1. Safety valve which is replaceable under internal tank pressure. 2.1 Safety valves protect tanks and pipelines against unacceptably high overpressure. The function of the safety valves must be tested at specific time intervals. If a safety valve which is replaceable under internal tank pressure is screwed out in conjunction with a closing valve, the tank has no safety valve during this replacement phase, that is to say it has no overpressure protection. 2.2 If the valve closing cone 6 is provided with an acoustic warning and signalling device 3 on the side facing away from the flow, that is to say on the pressure tank side, this device is triggered as soon as the safety valve is screwed out and thus provides a penetrating and continuous warning to reinsert a new safety valve. 2.3 Especially for liquid gas tanks with a propane-butane filling, this device is suitable for recurrent testing of the safety valve, without having to empty the pressure tank. <IMAGE>
