Title: Control of exhaust and inlet valves of multi-valve IC engine - involves two load exchange valves for each cylinder with individual cam per valve on common camshaft
Inventor: SCHREIBER KLAUS-HAGEN
IPC: F01L1/26
Filed: 1992-10-31
Abstract: The second cams (13) are rotatable as separate components on the camshaft (4) and axially displaceable between a first (13') and a second axial position.

Patent DE-4238788-A1 (DE)
Inventor: IFRIM VASILE DR
IPC: F16H1/34
Filed: 1992-11-17
Abstract: An epicyclic roller gear (100) has two rings (1 and 4) provided with an inner profile. One ring (1) is fixed and the other ring (4) is parallel or coaxial to the first ring (1) and rotatably mounted with respect thereto. The number of teeth on the two rings is different. Both rings (1 and 4) have at least two parallel inner profiles (1.1, 1.2, 4.1 and 4.2) which are offset in the circumferential direction by a fraction of the pitch of the profile or teeth. When the gear has only two mutually offset inner profiles, they are mutually offset by half the pitch of the teeth, so that in this case the gaps between the teeth of one ring are occupied by the teeth of the second adjacent ring. This results in a high contact ratio with the corresponding complementary profiles of a rolling element, preferably a roller carrier (5) with rotary rollers which roll in the gaps between the teeth of the inner profiles. Because the rings have a different number of teeth, there results a relative torsion during each rotation of the rolling body. By providing sections having a different number of teeth and/or teeth of different shapes in the circumferential direction, the output speed can be varied, and if required the output may even be stopped for a short time or its direction of rotation may be reversed. This in turn may be used to convert, through the gear (100), a reciprocal movement acting on such a ring into a movement of rotation in a single direction.

Patent DE-4308227-A1 (DE)
Title: Measuring element
Inventor: KONZELMANN UWE DR
IPC: G01F1/698
Filed: 1993-03-16
Abstract: Known measuring elements for determining the mass of a flow medium have a substrate with a relatively narrow slit, provision being made of a measuring resistor on a lip located downstream and separated off by the slit. The slit has a breadth which corresponds approximately to the thickness of the substrate. In the case of the measurement of the mass in the intake region of an internal combustion engine, disturbing fluctuations often occur which considerably impair the measuring result, in particular in the case of a strongly pulsating flow with partial backflow. The measuring element has a relatively broad slit (50), which subdivides the substrate (15) into two lips (40, 41) and has a slit width which amounts to at least 30% and at most 50% of the total width of the substrate (15), in order to obtain a constantly precise measuring result in the case of a pulsating flow by means of aerodynamic compensation. The measuring element according to the invention is provided for determining the mass of a flowing medium, in particular the intake air of internal combustion engines (Figure 2). <IMAGE>

Patent DE-4322101-A1 (DE)
Inventor: BERGMANN THORALD DR
IPC: H01J49/40
Filed: 1993-07-02
Abstract: In order to achieve a high mass resolution in a time-of-flight mass spectrometer with gas phase ion source, the initial-speed components in the acceleration direction of the ions must be kept small. This can be achieved in that the gas or ion beam to be investigated traverses the ion source at right angles relative to the acceleration direction. If acceleration direction and flight direction of the gas or ion beam to be investigated are not parallel, then the flight path is loaded with less gas ballast, the dynamic range of the mass spectrometer being increased as a result. The mass range of such an ion source is limited by the fact that heavy ions can be deflected too far from the axis of the ion source and can get lost as a result. When the deflection field is already located in the acceleration path, the mass range of this ion source can be expanded significantly. <IMAGE>

Title: Plastic transport crate
Inventor: KORTE KLAUS
IPC: B65D25/00
Filed: 1993-07-06
Abstract: The invention relates to a plastic transport crate, whose one end-face wall can be pivoted about an axis at its lower edge, is connected in the closed position by attachment means to the adjacent side walls and, in the open position, can be displaced in guides below the bottom of the crate. The object of the invention is to provide a simple possibility of opening the crate at the end face in two successive stages. The invention consists in the fact that the pivotable end-face wall consists of two parts which are arranged one above the other, whose upper part is connected by means of hinges to the lower part which can be pivoted outwards by about 180 DEG , and in the fact that each part has its own attachment means for attachment to the side walls. This pivotable end-face wall takes up very little space, can be opened in two successive stages and, in the open state, can easily be stowed below the bottom of the crate. It can be operated easily and is very sturdy.

Title: CD player objective lens with correction for chromatic aberration - uses cascaded annular surfaces on lens to vary optical path length within lens
Inventor: MARUYAMA KOICHI
IPC: G02B3/08
Filed: 1993-07-16
Abstract: An objective lens in a CD player system is designed to correct chromatic aberration by the variation of the optical path length within the refractive medium with radial distance from the lens axis or centre. The surface of the lens is formed in a normal concave or convex curvature and is also formed with a central region and concentric annular regions where the regions are stepped consecutively. The stepping dimension, t, is determined by the relation t = m.lambda o/(n-1), where m is (0, 1, 2, ...), lambda o is a nominal wavelength within the working region of the laser system and n is the refractive index of the lens. The width of the rings is inversely proportional to the square of the radius. ADVANTAGE - Chromatic aberration correction by simple low cost lens improving focus and resolution of data tracks on CD player system irrespective of variations in power level and temp. changes.

Title: Process for the production of optical layers
Inventor: FABER RALF DIPL ING
IPC: C23C14/35
Filed: 1993-10-15
Abstract: The invention relates to a combined sputtering and CVD device for the coating of substrates, especially for the production of optical multilayer systems, in which layers of high and low refractive index are applied in alternation in a uniform in-line coating unit. In order to take account of the differing pressures which occur in the course of sputtering and in CVD methods, the continuous reduction of a gas flow, and a constant partial pressure ratio, are used to approximate the pressure conditions so that it is not necessary to use devices for gas separation, for example slotted locks or pressure reduction stages.

Title: Optical inspection of products in a bulk goods stream
Inventor: MASSEN ROBERT PROF DR ING
IPC: G01N21/85
Filed: 1993-11-01
Abstract: A process and an arrangement are described for the automatic optical inspection of grain-shaped products which occur in a bulk goods stream. The products are individualised in one layer but may contact one another. The detection of the edges is carried out using a separate, image-transmitting triangulation system which continuously determines a height image of the product stream. The edge contours of the products are determined from this height image and are communicated to the image computer for the actual surface inspection. Various processes for obtaining the height image rapidly and overlaying it with the inspection image are described.
Patent DE-4338664-A1 (DE)
Inventor: LINDNER BERND
IPC: B41F27/12
Filed: 1993-11-12
Abstract: The invention describes a method and a device for controlling an automatic plate exchange process in a sheet-fed offset printing machine, in which a used printing plate is removed from the gripping region of a clamping rail assigned to the leading edge of the plate cylinder and a new printing plate is then introduced into the opened gripping region, fixing of the in-register position of the newly introduced printing plate taking place before the gripping region is closed (clamped). This method is to be designed in such a way as to result in increased safety and reliability in the course of the plate exchange process. Before it is established whether the newly introduced printing plate lies in register in the gripping region of the clamping rail, it is checked whether the used printing plate has been removed from the gripping region, for which it is established whether the used printing plate is not in an in-register position with its leading edge. <IMAGE>
