Title: Distancing device for work rolls - ensures their easy and safe exchange
Inventor: BENDER HANS JUERGEN
IPC: B21B31/10
Filed: 1992-09-04
Abstract: The work rolls are moved apart by piston units located in fixed blocks (11) which act on the roll chocks. Once apart, a distancing rod (19) is pushed into place between the chocks by a further piston unit (20). The rod is connected to the piston (20) by a permanent magnet (26). When in position, the rolls are allowed to rest on the rod (19) and are slid horizontally out of the roll frame. The rod (19) is initially located in a cylindrical section (18) of the block (11) with seals (36) fitted to the end of the section and to guide cover (33) attached to the end of the piston-cylinder unit. The rod (19) is made of non-magnetic material with the permanent magnet fitted tightly inside the rod with the magnetic face (27) level with that of the rod (28). USE/ADVANTAGE - Esp. in four-high roll frames. Exchange time is reduced and automatic control during the exchange ensures that personnel do not have to enter the dangerous area around the roll frame.

Title: Steady-state operated internal combustion engine with emission control
Inventor: VOGELSANG FRIEDRICH WILHELM
IPC: F02D41/14
Filed: 1993-04-10
Abstract: The steady-state operated internal combustion engine, in particular using a fuel gas, such as natural gas, has a device for emission control which comprises a lambda probe and a catalytic converter arranged downstream of the latter in the exhaust gas line. The lambda probe is part of a control which adjusts the mixture of fuel gas and combustion air on the fresh gas side to operation in the region of the lambda window. In order to further improve the emission control, a second lambda probe is arranged downstream of the catalytic converter in the exhaust gas line, the said second lambda probe being assigned to a second control circuit which forms a cascade control with the control circuit of the first lambda probe and which adjusts the desired lambda value of the first lambda probe when the actual value of the second lambda probe leaves a desired value range. In this process, an interference pulse leading to a brief change in this desired lambda value is initially applied in the direction of a lean fuel/air mixture and directly afterwards in the direction of a richer fuel/air mixture if the actual value of the second lambda probe has not left the desired value range over a defined time interval.

Title: Analog to digital converter circuit having a high dynamic range
Inventor: BAUMGARTL RUDI DIPL ING
IPC: H03M1/18
Filed: 1993-06-09
Abstract: An analog to digital converter circuit for digitising an analog radio-frequency signal which is amplitude-modulated with a modulation signal comprises an analog input (2), a digital output (4) and an analog to digital converter stage (6) having a stage input (8) and a stage output (10). The stage input (8) is connected via a controllable-gain amplifier stage (12) to the analog input (2), and the stage output (10) is connected via a controllable digital divider (14) to the digital output (4). An input (16) of a quantisation stage (18) is likewise connected to the analog input (2). The quantisation stage (18) emits control signals at control outputs (20), as a function of discrete amplitude values. The control outputs (20) are connected to amplifier control inputs (22) and to divider control inputs (24). A gain is assigned to each control signal, so that the maximum amplitude which is assigned to each discrete amplitude value is only just digitised without distortion by the analog to digital converter stage (6), after the amplification. A divisor is likewise assigned to each control signal in the divider (14), which divisor corresponds to the reciprocal of the gain, as a result of which the effect of the gain is cancelled out again in the digitised radio-frequency signal. <IMAGE>

Title: Cavity (cavern)-module rotor (CMR) for vertical-axis wind power systems (VA-WPS)
Inventor: GEHRA LUDWIG
IPC: F03D3/06
Filed: 1993-08-04
Abstract: The "cavity-module rotor" is an open rotor system having, e.g., four cavity modules (CM) of dagger-type design which are constructed horizontally or vertically as incident-wind flow elements. With the forwardly open cavity halves and rearward module closure, as well as with in each case one inner and a plurality of outer cavities, they are rounded upwards to the rear, and are designed in accordance with the concept to be voluminous. A partition wall stabilises the joint by means of T-grooved profiles and mutual bolting. In accordance with Fig. 1 (horizontal construction), the CM are mounted at an angle of 45 DEG  on short and long bracing supports (BS) per 90 DEG  segment. The CM permit the wind to be applied on two sides over a relatively large proportion of the rotor circumference. In the case of a horizontal CMR, the partition wall receives the BS holders at both ends via latching rails. The vertical CM with the same operating principle at an angle of 45 DEG , 90 DEG  segment, has at the centre of gravity three vertical anchorages for the BS holders. Drainage shafts on the BS underside discharge rainwater and prevent the formation of clumps of snow, etc. The CM building material is preferably fibre composite material. The horizontal CMR is a true alternative for coastal shipping (coastal trading, cabotage); both types of CMR are to be used for isolated operation (solitary operation) and can be integrated into wind farms. For dry coastal areas, the horizontal CMR in a VA-WPS is particularly suitable for supplying power and drinking water. <IMAGE>

Title: One-part plastic snap hinge
Inventor: WOEBCKEN WILBRAND PROF DR ING
IPC: E05D1/02
Filed: 1993-10-14
Abstract: The invention relates to a one-part snap hinge produced by injection moulding and consisting of resilient plastic, the two hinge parts of which are connected to one another via film hinges and at least two intermediate elements consisting of a plurality of spring elements. The spring action necessary for the snap effect is brought about by intermediate elements in the form of sheet-like tension springs, the flexurally elastic sickle-shaped spring elements of which extend parallel to the outer surface of the hinge parts in the closed state of the hinge. Advantageously, during the pivoting of the hinge parts, the intermediate elements are essentially subjected to bending stress, the bending stress being distributed virtually uniformly over the entire length of the intermediate elements.

Title: Ceramic component containing a cermet electrode
Inventor: RECKZIEGEL ARNO DR
IPC: C04B37/02
Filed: 1993-10-20
Abstract: A ceramic component, in particular a ceramic tube for a magnetically inductive measuring apparatus, contains, in a drilled hole (10), a cermet electrode (12) which has been inserted into the drilled hole (10) prior to sintering and has subsequently been sintered in during sintering. This ceramic component should be further configured such that, on the one hand, a reliable seal is ensured and, on the other hand, unacceptable overvoltages are avoided. As a solution, it is proposed that the cermet electrode (12), which is configured as a rod, has a convex shape and/or the drilled hole (10) has a convex shape with the smallest diameter in the centre. Furthermore, the cermet electrode (12) is inserted into the drilled hole (10) in the green ceramic and is sintered with the latter in such a way that plastic deformability of the materials in the electrode region gives a highly vacuum-tight but low-stress electrode joint. <IMAGE>

Patent DE-4338503-A1 (DE)
Inventor: DECKER ANDREAS
IPC: E04B7/20
Filed: 1993-11-11
Abstract: The under-roof construction serves for the fastening of different roofing panels on roofs which are insulated by rigid-foam panels. Fastened on the rafters are retaining angles (2) which serve for securing the laminated rigid-foam panels (5). In the region of the joint, separate batten head carriers (3) are fitted into the retaining angles. The batten head carriers (3) exhibit fastening parts for receiving batten head rails (4) at regular intervals from one another, i.e. in the direction of the eaves. A plurality of batten head rails may be fastened with respect to one another on a batten head carrier, with the result that a plurality of roofing panels may also be fastened with respect to one another with the aid of a retaining angle and of a batten head carrier. By using three parts (retaining angle (2), batten head carrier (3) and batten head rail (4)), universal usage, utilising standardised rigid-foam panels, is possible. There are relatively few joints, the number thereof being predetermined by the dimensions of the rigid-foam panels. The construction is stable since the corresponding sections of the batten head carriers overlap one another. The number of heat bridges or cold bridges caused by the joints is small. Mounting is simple and thus possible in a cost-effective manner. The resulting joints of the rigid-foam panels are closed, by the lamination of the upper side of the panels, by a corresponding, overlapping width and may even be adhesively bonded. <IMAGE>
