Title: Operator's platform for a utility vehicle which can be operated in pull and push mode
Inventor: EPPLE JOHANN
IPC: B62D33/06
Filed: 1988-03-10
Abstract: In the case of utility vehicles in which the driver's seat is mounted on a support which can be rotated through 180@ for the purpose of being able to use the vehicle in pull or push mode, and a steering column, which supports the steering device, is articulated about a horizontal transverse spindle on the support, the support previously extended a good distance into the leg room where it represented a considerable obstacle to the freedom of movement of the driver. The intention accordingly is to make available a more comfortable operator's platform for utility vehicles of this type. This is achieved by virtue of the fact that that boundary of the support (7) which faces the steering column (9), lies, when seen in the direction of travel, behind the front boundary surface (8a) of the seat (8) and that that end region (9b) of the steering column (9) which is articulated on the support (7), is designed in a manner such that its surface which faces the steering wheel (10) is flat and in the operational position of the steering column (9) is accommodated recessed in a recess (15) in the floor (13) of the operator's platform in a manner such that it is at least approximately level with the surface. <IMAGE>

Patent DE-3842816-A1 (DE)
Title: Wormgear mechanism
Inventor: ARNDT FRANZ MARTIN
IPC: F16H57/04
Filed: 1988-12-20
Abstract: The internally screwed convex-concave double enveloping wormgear mechanism manufactured from hardened steel, steel, cast iron, or bronze with straight, hollow or crowned flanks has reduced lead curvature differences by virtue of lead function optimisation by means of a large transmission ratio, large worm radii, a reduced wheel-tooth width and an increased wheel-tooth height. By virtue of the internal helical gearing according to the invention, the centre distance, which is considerably smaller than the part circle radius of the globoid wheel, gives an increased output per unit volume and a reduction in the pump power loss. The production costs in relation to comparable, multi-stage gear mechanisms are lower due to a saving in the weight of materials by virtue of the approximately cubic shape of the gear casing (12), globoid-wheel rings (1, 2) and hydrostatic segment support by bearing segments (7) on the inner bearing cage (3). The approximately ideal positional fixing of the enveloping worm (1) relative to the globoid wheel (2) in the engagement area can be kept largely constant by means of hydraulic control valves and their sensor-and computer-program-controlled regulation as a function of the mechanical spring constant of the gear mechanism, the viscosity of the lubricant, the shear stress friction and the output torque. The energy savings in the construction and operation of the wormgear mechanism according to the invention have the effect, in combination with a large power throughput, of a significant long-term saving of capital and meet environmental protection requirements, inter alia by noise reduction due to the globoidal transmission of power ...

Title: Low-leakage hydraulic coupling
IPC: F16L37/23
Filed: 1989-02-11
Abstract: A hydraulic coupling consists of a socket valve (4) and a plug valve (2) which open one another counter to spring force during the plug-in movement. In its plug housing (18), the plug valve (2) has a valve element (22) guided in such a way as to be axially movable. In the socket housing (40), the socket valve (4) has an inner sleeve (52), which is supported so as to be axially displaceable by endwise contact with the plug housing (18) and has a valve seat (64) that interacts with a valve element (66), and a fixed countertappet (60) which rests against the valve element (22) of the plug valve (2) in order to open the latter. According to the invention, the countertappet (60) has the valve element (66) that interacts with the valve seat (64) of the inner sleeve (52) in the region of its end facing the plug valve (2) and consequently the valve element (66) is arranged in a fixed position in the socket housing (40). <IMAGE>

Title: Magnetic coupling for contactless transmission of forces out of sealed chambers
Inventor: GAST THEODOR PROF DR ING
IPC: H02N15/00
Filed: 1989-02-21
Abstract: Magnetic suspension couplings are used, for example in weighing technology, in order to transmit the weight of a sample out of a sealed reaction chamber. The suspension state is generally achieved by continually monitoring the suspension body position using a contactless sensor and correcting it using an electromagnet. However, position sensors imply limitations in construction and range of use. In addition, they can cause errors by zero-point drift. The magnetic coupling according to the invention (see drawing) is free of these disadvantages: the electromagnet (1) is also used for detecting the speed v of the suspension body. This is set to 0 with the aid of the regulator (5). The suspension body then assumes the position z in which the magnetic attraction force is equal to the weight, since it is only here that the speed can permanently equal zero. In the steady state, the average coil current is also zero, provided that the voltage at the comparison point of the unit (6) is also zero. By providing a different voltage value, a different suspension separation z can be set. <IMAGE>

Title: Process for generating a working gas stream
Inventor: BORT HARTMUT DR RER NAT
IPC: G05D23/13
Filed: 1989-03-20
Abstract: The invention is based on the object of providing a process by means of which a working gas stream can be generated, which can be controlled as accurately as possible with respect to temperature and flow rate. In the process according to the invention, the temperature and the flow rate of the working gas stream (3) are controlled by means of the flow rates of two partial gas streams (1, 2), the temperature of the first partial gas stream (1) lying below and the temperature of the second partial gas stream (2) lying above the desired temperature of the working gas stream (3). In this case, temperature and flow rate of the working gas stream (3) are measured and at least the measured value of the temperature is detected by means of a measuring and control unit (4), which controls the flow rates of the individual partial gas streams via two flow control units (5, 6), one of which respectively each controls the flow rate of one partial gas stream (1, 2), as a function of the differences between the desired values and actual values of the temperature of the working gas stream (3). The process according to the invention is used for generating a cold working gas stream for cooling in the production of optical waveguides. <IMAGE>
