Title: Drive arrangement for a heavy vehicle
Inventor: HAGIN FAUST DIPL ING
IPC: F16H47/04
Filed: 1987-10-01
Abstract: The invention relates to a drive arrangement for a heavy vehicle with a hydromechanical torque dividing transmission (2) between engine (1) and final drive train (5), with a planetary differential transmission (4) and two hydraulic converters (5, 6). The object in this is to improve the said drive arrangement so that an increased drive torque for the final drive train can be made available at least virtually in the entire operating range of the vehicle. For this purpose, an adjustable hydraulic converter (39) is assigned to the torque dividing transmission (2), which converter is employed differently in two different operating ranges of the vehicle, that is   a) in the range noutput:ninput </= 25% as torque-increasing starting aid, the converter being coupled to a gear train connected to the transmission output shaft (13) and uncoupled from the said gear train again at the end of this range, and b) in the range noutput:ninput > 25% as drive support or in some other function, the converter, coupled by way of another gear train, being connected to a shaft of the torque dividing transmission (2).   <IMAGE>

Inventor: BROZE GUY
IPC: C11D3/20
Filed: 1987-10-24
Abstract: The anti-gel and dispersibility properties of a built nonaqueous liquid nonionic surfactant laundry detergent composition are improved by the addition of heyxlene glycol to the composition. The addition of hexylene glycol reduces the plastic viscosity of the composition with little or no adverse affect on yield stress value of the composition or adverse affect on the physical stability of the composition. The further addition of propylene carbonate or acid-terminated nonionic surfactant to the composition reduces the apparent viscosity of the composition and increases the dispersibility of the composition.

Title: Forceps for bipolar coagulation
Inventor: HEBI FRITZ
IPC: A61B18/14
Filed: 1987-11-17
Abstract: Two resilient legs (11, 12) and an end-piece (10) which is designed with a bipolar plug (30) are made in one piece of an electrically insulating, sterilisable plastic. A working part (25 and 26, respectively) of metal is embedded in the distal end of each leg (11, 12) facing away from the end-piece (10). Each working part (25, 26) is electrically connected to the plug (30) via a line (23, 24) of low flexural strength in comparison with the associated leg (11 and 12, respectively). This results in a comparatively light-weight forceps causing little fatigue to the surgeon using it. <IMAGE>
Patent DE-3800871-A1 (DE)
Title: Wideband sound transducer
Inventor: RIEDER JOACHIM
IPC: H04R7/02
Filed: 1988-01-14
Abstract: Since it has become possible to record music in almost perfect form, the defects of conventional sound transducers have an increasingly severe effect. The greatest defect of these transducer systems is that they radiate the sound not from one point and one plane and, due to the cross-over network, not at the correct time, either. Nor can these sound transducers reproduce any squarewave pulses which occur in music and voice, at least for a short time due to the mixing of different frequencies. It can be observed all over the world that attempts are being made to make diaphragms of electrodynamic sound transducers ever more mechanically rigid. There are also some such sound transducers which, instead of the conventional conical diaphragm, have a flat diaphragm. To make this flat diaphragm rigid, however, is more difficult. The invention then describes the opposite approach by deliberately designing the sound-radiating surface to be elastic which is achieved by the fact that a more or less large area and mass is moved depending on frequency. This design allows the entire sound spectrum to be radiated from one point and one plane and does not require any cross-over network. In addition, this design is capable also of reproducing squarewave pulses. A significant advantage is also its low cost. A surface of this type can be produced very inexpensively, only one drive is needed and the cross-over network is omitted altogether.
Patent DE-3802839-A1 (DE)
Title: Pressure-relief valve working free of friction
Inventor: QUANTE HEINRICH
IPC: F16K17/04
Filed: 1988-02-01
Abstract: Pressure-relief valves are used for the most varied purposes in order to protect downstream units or equipment when there is a corresponding sudden increase in pressure. In underground mining they serve to protect the hydraulic face support, in particular when rock bursts occur. A low-maintenance pressure-relief valve working free of friction works with a tube which serves as a sealing element, is arranged in a loop shape in an annular space and is secured to both the displaceable piston and the housing. Pressure fluid penetrates into the annular space and thus into the corresponding loop of the tube owing to the fact that further radial bores are arranged at a distance from the radial bores in the piston, via which further radial bores the pressure medium, as explained, can penetrate into the area of the annular space. The tube then seals the radial bores as long as the spring force is higher than the pressure of the pressure medium in the piston. If the pressure in the piston increases, the piston is displaced against the force of the compression spring and the tube unrolls so that the radial bores are opened and the pressure medium can escape through the spring space into the atmosphere, and in fact until the excess pressure is removed. The piston is then pushed back into its initial position and the valve forms a seal again. <IMAGE>

Title: Machine for removing skin or rind
Inventor: SCHILL HERMANN
IPC: A22C25/17
Filed: 1988-11-02
Abstract: A machine (1) is used for skinning meat or fish or for removing the rind from bacon. The material to be processed is guided by a drawing roller (4) towards a blade (6). In order to hold the drawing roller, which is provided with a toothing (10), in a non-sliding fashion, there must be removal of residues hanging from it. To achieve this, there is provided a cleaning device (8) having a cleaning roller (9) and strippers (13) which engage in annular grooves (12). The toothings of the drawing roller (4) and the cleaning roller (9) are both essentially the same and have tooth profiles which are arranged in symmetrical or radial planes. Furthermore, the tooth profiles of both toothings have straight surfaces. As well as being easy to produce, such toothings ensure a particular advantageous engagement which ensures that the drawing roller (4) is cleaned thoroughly. The cleaning roller (9) can be subjected to pressure in the direction leading towards the drawing roller (4), especially in order to compensate for diameter tolerances and in so doing to ensure that contact with the drawing roller (4) remains consistently good. Furthermore, the cleaning roller (9) is also displaceable in an axial direction and is connected to a drive to permit oscillation (Figure 1). <IMAGE>

Title: Visual aid spectacles and make-up spectacles model A, B and C, the individual parts being mutually exchangeable as in a so-called building block system
Inventor: ROTHSTEIN HELGA
IPC: G02C5/00
Filed: 1988-12-28
Abstract: These are so-called HALF-SPECTACLES, which are to make it easier for wearers of spectacles to put on make-up and for wearers of contact lenses to insert the contact lenses, and, in the case of the latter, to put on make-up subsequently, by leaving out the rather disturbing parts of the second half of the spectacles which are common in case of commercially available make-up spectacles. These make-up spectacles consist of only one glass (1) in a metal frame (2). The lateral part (6/7) is connected to the frame by means of a hinge (8) and consists of the so-called temple bow (6) and of the ear bow (7) connected thereto by means of a second hinge (8-2). A nose bow (3) which has only half the length is fitted to the frame on the left-hand side with the pads (4) which are fastened to its free end. The ear bow directed downwards and the pads, likewise pointing downwards, can be rotated upwards about 180@ by way of the threaded parts (9) and (5) so that this half-part of the spectacles can then be placed on the other, left-hand side of the face which was previously free and to which make-up could therefore be easily applied (and to which make-up has now already been applied). These half-spectacles can, in addition, be folded together by way of the two hinges (8-1) and (8-2), inwards to form a very small frame. <IMAGE>
