Title: Boring tool with remote diametral adjustment - has finishing tool bit mounted on tilting beam supported against opposed wedges in central drawbar
Inventor: SCHEER GERHARD
IPC: B23B29/034
Filed: 1990-07-16
Abstract: The principle is shown applied to a combined roughing and finishing tool with a roughing toolbit (13, 14) and chamfering toolbit (13`, 14`) set in the tool body (10), and a finishing toolbit (15, 16) clamped to a beam (18) which tilts about the central pivot (20) fixed in the tool body. Spherical ended pins (36, 38) at each end of the tilting beam support it against opposing wedges (28, 30) recessed in the drawbar (34), so that when the drawbar is moved under hydraulic or servo-motor control the beam (18) tilts and causes radial adjustment of the finishing toolbit.

Title: Transmission drive with periodically changing ratio - has eccentric gear timing and variable transmission element
Inventor: MARTENS JOERN
IPC: F01C1/077
Filed: 1991-02-09
Abstract: The transmission translates a constant drive into a periodically variable ratio drive. The periodic variation is obtained by two gear trains with selected eccentricity, the outputs being combined by a third train. The latter is variable to vary the overall gear ratio of the system. The principle can be operated in either direction. For manually propelled vehicles the periodic torque supplied by the operator is changed into a constant drive. Alternately, a constant drive is changed into a controlled periodic drive, e.g. for artificial heart pumps. The selection of the eccentric elements controls the periodicy. ADVANTAGE - Simple transmission lay-outs.

Title: Combined spring-damper hydraulic unit - incorporates temp. variation compensating system
Inventor: MENKHOFF KARLHEINZ
IPC: F16F9/30
Filed: 1991-03-02
Abstract: This spring/damper unit incorporates two pistons (1&2) which slide relative to each other and within a housing (3), by reduced temp. the density and spring rate will fall. At low temp. the first piston (1) will travel further effectively decreasing the volume of the first cylinder (4), increasing density and spring rate to the original value. The effect of this is to maintain the pressure on the second piston (2) constant. The system negates the effect of temp. variations. To compensate for reduced spring length the piston cylinder system (4) can be driven down out of the second cylinder (5). USE/ADVANTAGE - Spring-damper unit compensates for changes in temp.

Patent DE-4118699-A1 (DE)
Inventor: BECKER ROLF DIPL ING
IPC: B62D109/00
Filed: 1991-06-07
Abstract: Four-wheel steering system for a motor vehicle in which at least one axle is of steerable design. The steering movements of the wheels are effected as a function of the intention of the driver and/or of variables which represent and/or influence the driving condition. According to the invention, driving conditions in which a deceleration of a certain, selectable magnitude is present are detected. During these driving conditions, steering movements which are dependent on variables which represent and/or influence the driving condition are at least reduced. In particular, steering movements in the opposite sense during braking manoeuvres starting at high speeds are prevented on vehicles with four-wheel steering. To improve directional stability during braking, steering movements of the front and rear wheels in the opposite sense which usually occur below a threshold vehicle speed are reduced or prevented if the vehicle is decelerating from a higher speed as detected by comparing wheel or vehicle speeds, whether the anti-lock braking system is operating or whether the brake pedal was pressed above the threshold speed. In a modification opposite steering is reduced only if the vehicle is also cornering as detected by steering angle sensors or by comparison of left and right wheel speeds.

Title: Spinning bath vapour condensing - uses the spinning bath to cool the recirculation sulphuric acid used for water condensation
Inventor: EBNER KARL
IPC: B01D3/06
Filed: 1991-06-27
Abstract: To condense the vapours emerging from spinning baths, with recirculating H2SO4, a spinning bath is used to cool the H2SO4 and is then cooled in a vacuum. The spinning bath is recirculated for cooling and part of the concentrated cooled bath is taken to be mixed with an equal vol. of new spinning bath. The water vapours are drawn off during cooling, and condensed with cold water. The spinning bath is cooled in a number of successive stages. The vapours from each cooling stage are condensed in an acid mixt. condenser, and the H2SO4 is circulated and recooled by the spinning bath in a separate heat exchanger. The condensers, using H2SO4 are in series and part of the H2SO4 from each condenser is passed to the next condenser. At the final condenser, part of the H2SO4 is extracted and an equal vol. of fresh H2SO4 is added to the first condenser. The heat exchangers are in series, with the same spinning bath flowing through them for cooling. The H2SO4 concentration increases from the initial condenser to the highest level at the final condenser. USE/ADVANTAGE - The system is used in rayon spinning where, according to the compsn., the spinning bath is cooled from 35-40 deg.C to 0-15 deg.C with simultaneous steam evapn., and the sodium sulphate is crystallised out as mirabilite. The method increases the cost-effectiveness of vacuum cooling and crystallisation assemblies where the vapours are condensed by recirculating H2SO4 on cooling the spinning ba
