Patent DE-3533783-A1 (DE)
Title: Machine or machine parts executing gyratory movements, such as, in particular, size reduction machines
Inventor: HEINZ ENGELBERT DIPL ING
IPC: B02C2/04
Filed: 1985-09-21
Abstract: The invention proposes a machine which, in general terms, executes gyratory movements and is intended, in particular, for the size reduction and processing of rock or the like, which is fitted with a plurality of radial and/ôor thrust rolling bearings to which it may be difficult to gain access. To avoid the necessity of first disassembling these bearings, at least the cages of the bearings are provided with through holes. It is now possible, on the one hand, to check the bearings from outside by means of suitable checking devices and, on the other hand, the openings have the effect of increasing the lubricant throughput. <IMAGE>
Patent DE-3538391-A1 (DE)
Title: Process for reducing a carbonate content in sodium hydrogen sulphide liquor
Inventor: SCHINKEL FRITZ DIPL ING
IPC: C04B7/24
Filed: 1985-10-29
Abstract: In order to utilize hydrogen sulphide-containing gases which contain carbon dioxide as an accompanying constituent, for producing merchantable sodium hydrogen sulphide liquor, the inevitably formed carbonate must be largely removed. The only method known hitherto for this purpose is precipitation with barium salts or limewash, this process being expensive and generating a very smelly waste sludge. In order to overcome these drawbacks, carbonate-containing sodium hydrogen sulphide liquor, whose carbonate content is to be reduced, is brought into intimate contact with granular materials having a large surface area or with cement clinker. The material having a large surface area or the cement clinker is washed after use with aqueous sodium hydroxide and steam condensate, and the cement clinker is reused in the cement works.

Patent DE-3603977-A1 (DE)
Title: Method for digital transmission of phase-modulated analog signals
Inventor: HESSENMUELLER HORST DIPL ING
IPC: H04J3/04
Filed: 1986-02-08
Abstract: In order to be able to transmit phase-modulated analog signals, in particular frequency-modulated radio signals, via digital line paths, only the intervals between their consecutive zero passages are digitised and transmitted as an equidistant string of equal-length code words following conversion at the transmitting end to an intermediate frequency which is as low as possible. The intervals between the zero passages are reconstructed from these code words at the receiving end and from them the rectangular phase-modulated output signals are obtained which, following their passage through a reception low-pass filter and after corresponding frequency conversion, can be fed to the input of a conventional FM receiver. Up to 11 frequency-modulated stereo radio signals can be transmitted at a bit rate of 34 Mbit/s with a 10-bit coding and 1024 time stages. <IMAGE>

Patent DE-3616567-A1 (DE)
Title: Process for producing thick sprayed metal layers
Inventor: LEUZE GERHART
IPC: C23C4/02
Filed: 1986-05-16
Abstract: To produce a thick sprayed metal layer (16) which firmly adheres to a substrate (10) in spite of internal stresses, it is proposed first to apply to the substrate (10) an epoxide adhesive layer (12) onto which a thin sprayed metal layer (14) of aluminium or zinc is sprayed immediately after the application. The adhesive layer (12) is then caused to cure, and the thick sprayed metal layer (16) which, for example, consists of chromium-containing steel, is then applied to the structure thus obtained. <IMAGE>
Patent DE-3641191-A1 (DE)
Inventor: KRENKEL BERNHARD DR
IPC: D21F3/02
Filed: 1986-12-03
Abstract: The invention relates to a method of the manufacture of dimensionally stable, liquid-impermeable, flexible press bands, particularly for wet presses of paper making machines. With known manufacturing methods for such press bands, the provision of a structured surface for liquid discharge on the outer surface of the press band, which faces the fibrous web or the felts, is achieved either by reversing the press band after removal from the casting mould so that the structured surface becomes the outer surface of the band while the smooth surface forms the inside thereof, or by grinding drainage ducts into the outer surface of the press band. But especially in the case of small band diameters, reversing of such cast press bands causes serious problems and entails considerable expenditure, wherein the risk of damage to the band cannot be excluded and grinding of the drainage ducts is just as expensive. To simplify the manufacturing process and to eliminate reversing of the press band after removal thereof from the casting mould, the inner wall of the centrifugal tube is provided with cavities and/or depressions which upon casting of the free-flowing mixture are filled therewith to form raised surface portions on the outer surface of the finished press band, so that in a subsequent pressing operation liquid to be discharged may be drained between said raised portions, and the completely cast press band is ground to finished size on the inside thereof.
Patent DE-3642503-A1 (DE)
Title: Lockable differential
Inventor: LOMMERZHEIM MANFRED
IPC: F16H48/30
Filed: 1986-12-12
Abstract: A lockable differential for motor vehicles is described. In order not to place an additional load on or to relieve the bearing points between the differential case (2) and the transmission case (1) in a locking sequence, the invention provides for an additional piston (26, 27), which counteracts the reaction forces produced by the pressure piston (20, 21). In one embodiment, the additional piston (26, 27) presses directly on a bearing ring (3a, 4a) of the rolling-contact bearing (3, 4) between the differential case (2) and transmission case (1). In another embodiment, the compensating piston (26) presses by way of a wheel drive shaft (6) and axle drive gear (10) on the differential case (2) and in so doing relieves the pressure load, which is introduced into the differential case (2) by the pressure piston (20). <IMAGE>

Patent DE-3709397-A1 (DE)
Inventor: GENUIT KLAUS DR
IPC: H04R5/027
Filed: 1987-03-21
Abstract: The invention relates to an interface in the transmission between the sound receiving and reproducing sides in an electroacoustic transmission system, based on the theoretical operating system of the outer ear taking into account the physical principles of the transmission operation of the outer ear, whereby the spectral variations due to the direction-independent components on the sound receiving side and due to the direction-dependent components on the sound reproducing side are corrected, so that the sound receiving side has no effect on the direction-dependent parameters of the outer ear [the directionally neutral interface which is therefore independent of the sound field (free field to diffuse sound field)] and the sound reproducing side has no effect on the direction-dependent parameters of the outer ear. The invention thereby offers a technically feasible option for individual adaption of head-phone transmission properties.

Patent DE-3741858-A1 (DE)
Title: Power transmission device for retractable undercarriages for aircraft in weight classes (civil) E, G, F, I, K, H, gliders and corresponding aircraft for military use
Inventor: KLOTZ WILLI DIPL ING
IPC: B64C25/10
Filed: 1987-12-10
Abstract: The invention, published in P 2747697.7 on 26.4.79, of a retractable undercarriage for use in aircraft in the classes mentioned above is considerably improved, with respect to its function, by means of this invention in that, when the undercarriage is extended, a closing force is (additionally) produced by the structural parts for which a patent is applied, which closing force produces a reliable force fit between the undercarriage well and the incoming mating ring. In consequence, the mating ring is reliably prevented from springing out of the well in all load cases, even in the case of relatively large radial forces. At the same time, destruction or damage of the well/mating ring parts and other components is prevented. At the same time, rotation of the mating ring in the event of a wheel load on one side (to the rear in the horizontal direction) is suppressed.

Patent DE-3812107-A1 (DE)
Title: Lever brake
Inventor: SEELIGER KLAUS DIPL ING
IPC: B62L1/04
Filed: 1988-04-12
Abstract: Lever brake acting as a driving brake and parking brake on tyres of muscle-powered vehicles, in particular wheelchairs; as a parking brake effective according to the invention also in the event of diminishing or absent tyre air pressure. In the driving brake angular region of the hand lever H the latter must be actuated counter to the spring force F and the counter-force of the tyre C at the brake block B. In the event of further angular actuation of the hand lever H, the spring lever R assumes a dead point position with respect to the spring force F. Following this, under the influence of the spring force F, the spring lever R springs, with its connecting link L, further in the angular direction alpha  and now presses, without hand force on the hand lever H, via the pin S, the brake block B onto the tyre C. In the event of diminishing air pressure in the tyre C, the spring force F draws the brake block B automatically as far as the rim D. <IMAGE>
Patent DE-3812495-A1 (DE)
Title: Protective sleeve combined with a roll-back seal
Inventor: WEIDENWEBER MICHAEL
IPC: F16D65/18
Filed: 1988-04-15
Abstract: For a piston guided in a cylinder, especially in a brake cylinder for disc brakes, it is often necessary to provide a protective sleeve between the piston and the end of the bore to prevent the ingress of dirt into the cylinder space. The cylinder furthermore generally has a seal which seals off the cylinder relative to the piston, thereby preventing any of the pressure medium that drives the piston from passing through the gap between the piston and the cylinder. The invention has set itself the object of simplifying the production and installation of the protective sleeve and the seal. The invention consists, in principle in that the seal and the protective sleeve are fixed in the cylinder directly adjacent to one another. As a result, only a single groove is required for the retention of the two components. In an advantageous further development, the invention permits the integral connection of the two components. The invention also describes possibilities for the particularly space-saving design of the unit comprising the sleeve and the seal, thereby improving the sealing provided by the constructional unit created in this way. <IMAGE>
