Patent DE-4110862-A1 (DE)
Inventor: DIETERICH GUENTER ING GRAD
IPC: F16H57/02
Filed: 1991-04-04
Abstract: In the case of a switching device at least two switches (10, 11) are provided, which are each provided with a rotatably arranged control shaft (41, 42), the rotational movement of which brings about the actuation of at least one cam disk, triggering switching processes. The individual cam stages (12, 13, 14, 15) of the switches (10, 11) are each designed with a fixable internal gear rim, a rotatably arranged planet wheel carrier, on which at least one planet wheel is rotatably held, and with a cam disk. Planetary gearing is preconnected to the switches, on which gearing two drive shafts (35, 36) are rotatably mounted. Essentially the same parts are used in the gearing parts of the planetary gearing (34) as in the cam stages (12, 13, 14, 15) of the switches (10, 11). By means of this design a reduction of the manufacturing costs is achieved. <IMAGE>

Title: Water and oil emulsion disposal - uses an absorbent carrier for water to evaporate in air and oil is pressed out for collection
Inventor: GEORGII PETER
IPC: B01D17/02
Filed: 1991-05-18
Abstract: To dispose of an emulsion contg. water and oil, esp. metal-working coolant fluids, the water is evaporated under environmentally sound conditions.

Patent DE-4129781-A1 (DE)
Inventor: HAINDL HANS DR MED
IPC: A61M39/12
Filed: 1991-09-07
Abstract: A hose coupling has a tubular part (2) on which is slid the end of a hose to be coupled and means for retaining the end of the hose (13) on the tubular part. The tubular part (2) that extends from the housing (1) is conically enlarged towards its root, preferably like a trumpet. The hose end slid thereon is held by a clamping sleeve (6) having an inner squeezing edge (12) that is squeezed into the outer surface of the slid-on hose, reliably retaining the hose end on the tubular part, once the clamping sleeve has been linked with the housing, for example by means of a bayonet catch (8, 9), and at the same time pressing the hose end against the tubular part. A traction-resistant, durable, tight and easy to establish link is thus obtained. In the case of port-catheter systems, the length of the flexible catheter can be quickly and easily adapted to the prevailing conditions and subsequently coupled to the port.

Title: Controlling excavator with front mechanism - having joints for swivelling also rotary joints for turning and provided with joint angle sensors at corresp. joints for determining respective joint angles
Inventor: AWANO KATSUSUKE
IPC: E02F3/30
Filed: 1992-01-17
Abstract: The method includes computing the position coordinates of the ends of the rear arms, using the sensor results, related to the point (OE), based on the combination of the joint angle. The computed position coordinates are related to a basic coordinate system locally fixed w.r.t. a lower moving body of the hydraulic excavator. The translation and rotative speed of the point (OE) is predetermined for carrying out a desired working operation. The predetermined speeds are entered by means of electrical control levers (2a,2b,2c,2d) arranged in the cab to compute the position coordinates of the point (OE) after an elapsed time. The coordinates of the point (OE) described in a joint coordinate system are transformed into position coordinates related to the basic coordinate system. The differences between the present position coordinates of the point (OE) and the position coordinates after an elapsed time are determined and transformed into values related to the joint coordinate system. The transformed differences are multiplied with position adjusting factors for determining the angular speed differentials. These are transformed into the desired angular speeds of the respective joints. These are entered into a hydraulic control system, with all computing and transforming steps carried out using a computer arranged in the driving cab of the hydraulic excavator. ADVANTAGE - High working accuracy.

Title: Cable suspended hoisting carriage - is held in equilibrium by auxiliary rope drum and lifting rope gripping roller connected by reversing gearbox
Inventor: WERLBERGER JOSEF
IPC: B66C11/20
Filed: 1992-02-05
Abstract: Conventional hoisting carriages can only be held stationary at a desired position by clamping on the suspension cable. This is avoided and the carriage held in equilibrium by the use of a storage drum (4) and lifting rope gripping roller (7) which are connected by a reversing gearbox (6). Thus the gripping roller can be driven in the same or opposite sense as the storage drum (4). Wound round the storage drum is an auxiliary rope (5) connected at the other end to a fixed winching drum. The lifting rope (8) passes between the gripping roller (7) and pressure roller (9) to a second winching drum. ADVANTAGE - By approp. switching of the reversing gearbox drive and actuation of the two winching drums, light and heavy loads can be raised and lowered at any desired postiion of the carriage, which remains at rest under equilibrium of the forces acting on the two ropes. Loads can also be traversed at a constant height from varying terrain. The gearbox has a locked position.

Title: Viscous fluid type vibration damper - has facility to vary the flow cross=section during stroke to produce range of different damping force levers.
Inventor: DELAM HEINZ
IPC: F16F15/027
Filed: 1992-03-10
Abstract: A viscous fluid damper has a cylindrical housing (4) that contains a suitable fluid (6). Located coaxially in the housing is piston within a tube (3). Downwards movement of the tube and piston results in fluid being displaced in the space between the tube and the housing and a viscous damping force is generated. The force can be changed part way through the stroke by allowing a large cross-section piston (3a) to enter the fluid and so vary the fluid passage cross-section. An actuator may be used (7) to vary the point. The cross-section of the piston may also be varied to modify the damping action. USE/ADVANTAGE - For use in the attenuation of mechanical machine vibration. Allows damping action to be varied to suit conditions.
