Patent DE-19538270-A1 (DE)
Inventor: GRUNWALD PETER HEIN
IPC: G03B21/16
Filed: 1995-10-13
Abstract: The invention relates to a projector, in particular an overhead projector or an LCD projector in the style of an overhead projector, comprising a housing, which accommodates a light source quipped with an elongate metal-vapour lamp 3 and having a lateral light outlet 5 a blower 6 and at least one inclined mirror 7. The object of the invention is, using simple means, to afford protection against damage caused by explosion of the metal-vapour lamp and to achieve adequate cooling of the metal-vapour lamp and the components of the projector. The invention is arranged such that the blower is a tangential fan, the axis of which is disposed parallel to the geometric axis of the metal-vapour lamp, the blower being disposed above the metal-vapour lamp, with the air discharge gap 14 of the tangential fan directed towards the adjacent housing side wall, and having an air channel extending from the air discharge gap to the housing side wall, the top of which channel is formed by a downwardly bent or angled plate 17. Thus, the metal-vapour lamp is accommodated in the housing of the projector in such a way that, in the event of explosion of the metal-vapour lamp, fragments of the lamp are prevented from leaving the housing of the projector and causing damage. By means of the tangential fan, the axis of which is disposed parallel to the axis of the metal-vapour lamp, particularly efficient cooling is achieved.

Title: Printing embossed labels with improved pressure distribution for durable legibility
Inventor: DZIERSK WILFRIED
IPC: B41M1/24
Filed: 1995-10-11
Abstract: The hot pressing machine prints pre-embossed labels, esp. vehicle identification plates. Its heated pressing roller (8) has a rubber-surfaced carrier, and a counter-pressure roller (9). Spools (3,4) wind the blocking foil (5), advancing it between them. The plates are drawn between the rollers for printing, with a novel interposed arrangement of two or more pressure distribution rollers (16,17), running both against the pressure roller (9), and in line contact with the rear of the plate. This improves the printing quality. The clearance between the lines of contact is approximately the line width of the printed plate.  The counter pressure element is a static slide block, which may be Teflon (RTM), and which provides flat support over approx. the line width.

Title: Automatic central Willison type buffer coupling for railed vehicle
Inventor: BENSCH JOERG
IPC: B61G3/10
Filed: 1995-11-30
Abstract: The coupling has an extending lever (10) supported in a coupling head (1) with a projecting nose (11). The lever extends a coupling pin (3') to engage into a coupling pocket (4) of the opposite coupling head (1'). The coupling heads move in opposite directions orthogonally to the contact surfaces (14) of two bolts. After operation of the lever the force exerted at the contact faces is reduced, allowing the bolts to be removed. The coupling heads can then be disengaged, bolts reinserted and the heads separated by the application of spring or other forces.

Title: Method for rinsing observation area or operation field during endoscopy
Inventor: FARIN GUENTER
IPC: A61B1/12
Filed: 1995-12-06
Abstract: The method involves the use of fluid feed devices (14,15,16,17,19,20) that are formed that a fluid amount defining a fluid plug (13) is filled into a proximal section of the conduit (10). This fluid plug, by means of the gas, is introduced under pressure after the fluid amount into the conduit, is accelerated in the conduit, and with enhanced end or mouth speed is ejected out of the mouth (11) of the conduit. The form of the fluid feed devices is such that a number of fluid plugs are ejected one after the other, preferably with regular spacing. The feed devices may have first adjustment devices for adjustment of the fluid amount of one of each fluid plugs. They can also have second adjustment devices for adjustment of the pressure of the gas. Third devices can adjust the spacing between the fluid plugs during ejection.
Patent DE-19613407-A1 (DE)
Title: Motor control equipment for data recording and playback device
Inventor: NOMURA MASARU
IPC: G11B21/08
Filed: 1996-04-03
Abstract: The motor control equipment includes recording and playback equipment, a disc-shaped recording medium, a motor (10) to move the former over the latter, and an operating condition sensor (8). The compensation device (13) uses the input signal and a signal produced by the sensor to generate a compensation signal against external interference and changes in motor parameters.  The amplitude limiting device (13a) limits the amplitude of the signal fed to the compensation device. Limiting this signal ensures that the drive signal generated by the motor drive equipment (12) does not exceed the maximum value within its control range.
Patent DE-19614425-A1 (DE)

Title: Scanner probe exchange arrangement for coordinate measuring apparatus
Inventor: AEHNELT PETER
IPC: G01B5/012
Filed: 1996-06-13
Abstract: The exchange arrangement is for a probe which measures vertical displacement, in the direction of the slender scanner shaft (5). The displacement is of an amount which is noticeably larger than their mutual distance. The bearing has three bearing positions (22,23,24), with respectively two bearing points, and the straight lines (g1-g3), which connect the bearing points, lie in at least two different planes displaced in the direction of the scanner shaft (5). The bearing points (e.g. 12a,13b) lying in one plane, support the scanner in the direction of the scanner shaft, and the bearing points (24a,24b), in the second plane displaced to the first plane, support the scanner essentially vertically to the scanner shaft.
Patent DE-19626556-A1 (DE)
Title: Determining absolute phase between two interferometric images generated by synthetic aperture radar
Inventor: MOREIRA JOAO R DR ING
IPC: G01S13/90
Filed: 1996-07-02
Abstract: An unfiltered, folded in-phase element is subtracted from an a priori absolute phase element after initialising an iteration. The result is filtered, unfolded and added to the absolute phase. The standard deviation of the difference between the absolute in-phase and priori absolute phase elements is determined and compared with a previous standard deviation to determine whether to proceed with the iteration. The a priori absolute in-phase element is replaced with the last determined value and the old standard deviation is simultaneously replaced with the new value and the process returns to the first step or the iteration is interrupted, when an absolute in-phase element of a first form is achieved, enabling an accurate terrain model to be derived using the flight geometry.

Title: Box-mating scaffolding tubes - have end diameters enlarged or contracted by projection or inversions to form bayonet fastening on erection
Inventor: OERS PETRUS CHRISTIANUS JOHANN
IPC: E04G7/30
Filed: 1996-07-26
Abstract: One of the tube ends (7,9) is deformed so as to reduce the diametral tolerance to less than that of the tubes before deformation. Thus the play between the two tubes when inserted in one another becomes less than that prior to deformation. One end has a wall (15,17) projection (19,21), pref. a rib running along the tube (5), or again a number of different projections (23,25) can be provided in the tube walls. The projection may be on the outside of the first end wall. The other end has at least one further inversion with the result that the inversions on the walls of the tube ends complete a bayonet fastening.

Title: Determining compression pressure in supercharged internal combustion engine
Inventor: WENZLAWSKI KLAUS DR
IPC: G01M15/08
Filed: 1997-04-29
Abstract: The determination of the duration of fuel injection on an internal combustion engine which has fuel injection (22) and supercharging (30) requires a knowledge of the pressure loss at the injection nozzle which in turn depends on the cylinder pressure and the common rail pressure (27). The cylinder pressure may be found from the fact that the ratio of the maximum cylinder pressure to the admission pressure (32) on load is equal to the same ratio under deceleration and without injection for a given speed. The latter values are memorised as function of the motor speeds at test and used by the control unit (26) to determine the cylinder pressure.
