Patent DE-3719306-A1 (DE)
Title: Magnet for NMR tomographs and process for the production thereof
Inventor: WESTPHAL MICHAEL DR
IPC: G01R33/383
Filed: 1987-06-10
Abstract: The NMR tomography devices hitherto used in practice use either resistive or superconducting magnets, although resistive magnets have a high energy consumption and superconducting magnets require considerable technical effort because of the necessary cooling. Nevertheless, permanent magnets have not hitherto been able to gain wide use because of the difficulties associated with their production. The invention makes possible the simple production of a permanent magnet suitable for NMR tomography, by starting from a permanent magnetic material (44) in the form of a flexible strip (44) which is magnetised with a direction and intensity prescribed for each point of the strip and is then wound up into a body (43) forming at least one section of the permanent magnet and is fixed in the position then achieved, preferably by adhesive bonding (glueing). The magnetisation of the strip (44) is set in such a way that, in the wound body (43), the local magnetisations of the wound up material add up to a total magnetisation which gives at least a prescribed proportion of the magnetic field to be achieved with the permanent magnet. <IMAGE>

Patent DE-3726875-A1 (DE)
Inventor: SCHINGNITZ MANFRED DR ING
IPC: F23D14/22
Filed: 1987-08-12
Abstract: The burner is employable in chemical or gas industry for the vapour/ oxygen conversion of natural gas. The gas is fed to inlet (7) and mixes with oxygen exiting through pipes (17) at the mouth of the burner. To avoid the risk that the burner mouth is burnt away by reaction with industrial oxygen, an outer cooling jacket (3) terminates in a coolable base (16) spaced apart from the housing base (5) to provide a gap. Water fed from an inlet (12) passes around gas pipes (10) to the base an exits at outlet (4). Oxygen gas outlet pipes (17) pass through both bases (5) and (16). The bases (5, 16) may be concave. <IMAGE>

Title: Circuit for connecting and disconnecting signal DC voltages of different polarity as required
Inventor: NOTHDORF UWE ING GRAD
IPC: H03K17/74
Filed: 1987-08-26
Abstract: The signal DC voltage (+12 V, -12 V) is fed to one AC voltage input of a diode bridge circuit (D1 to D4); the other AC voltage input of the bridge circuit is connected by a load (V) to reference earth (0V). The two DC voltage outputs of the bridge circuit are connected to the switching path of a transistor (T). As long as the transistor is switched on, the signal DC voltage (+12 V, -12 V) is connected to the load via in each case two diodes (D1, D3; D2, D4) and the switching path of the transistor (T). If the transistor is switched to have a high impedance, then the bridge circuit decouples the signal source (PU) from the load in a high-impedance manner. The circuit is particularly suitable for making electronic level converters effective or ineffective as required. <IMAGE>

Patent DE-3737682-A1 (DE)
Title: Bridge-laying unit having armoured laying vehicle and bridge-part feeding wheeled vehicle
Inventor: WAGNER GERHARD DIPL ING
IPC: E01D15/127
Filed: 1987-11-06
Abstract: Development work during the course of a project for providing bridge means and crossing means has shown that the integration of an armoured bridge layer in a large-scale family concept is opposed by a number of problems. A too extensive logistic precondition here counteracts the optimisation in the special area of responsibility. A bridge-laying unit (1) for laying a bridge (4) which is supported at the end on the ground (10) and comprises at least two bridge parts (5, 6) is proposed, the feed wheeled vehicle (3) being provided with an armoured driver's cab (8) and with a front coupling device (9), in which a rear swivelling arm (11) of the armoured laying vehicle engages for coupling the feed wheeled vehicle to the armoured laying vehicle during the bridge-laying operation. In this arrangement, the feed wheeled vehicle is supported at the front and at the rear by means of laterally arranged levelling supports. By this means, bridge lengths of up to 40 m can be realised. The laying of the bridges takes place under full armoured protection quickly and reliably with a relatively low investment of economic means. <IMAGE>
Patent DE-3737994-A1 (DE)
Title: Cash-drawer arrangement
Inventor: KRAGE GEB ERDKAMP
IPC: G07G1/00
Filed: 1987-11-09
Abstract: Conventionally, cash-drawer arrangements contain a drawer in which usually the hard cash is accommodated in the front region and the bank notes are accommodated in the rear region. At a check-out work station with an integrated cathode-ray tube within the appliance insert, there is only a small space depth which cannot receive a drawer of this type. Two cash drawers, one for hard cash and one for bank notes, are arranged one under the other and coupled to one another in such a way that the lower cash drawer covers approximately double the pull-out distance of the upper one. The cash-drawer arrangement is used predominantly when space depths in check-out work stations are restricted.

Patent DE-3802262-A1 (DE)
Title: Device for controlling the idling speed
Inventor: HENNING MANFRED
IPC: F02D41/12
Filed: 1988-01-27
Abstract: Known devices have the disadvantage that the set air flow may be too great for the transition to the idle-speed control operating state and that in overrun conditions undesirable cooling of the combustion chambers occurs. To counter this it is proposed that, when the throttle is opened beyond a predetermined amount, the command signal is kept at the value which was delivered to the throttle valve as idling speed control value before opening of the throttle, that at the onset of overrun conditions, the command signal to the throttle valve existing prior to the overrun conditions is reduced in the throttle valve closing direction according to a predetermined time function, that following overrun conditions, at the onset of idling or load operation, the command signal is rapidly set to the value which was delivered to the throttle valve prior to the overrun conditions. The proposal has applications in an internal combustion engine with an air intake port in which a throttle is arranged and a bypass duct bypassing the throttle which, from a throttle valve, in accordance with a command signal delivered to the throttle valve from an electronic control module, assumes a position in which an air flow corresponding to the operating conditions is set. <IMAGE>
