Patent DE-3709349-A1 (DE)
Title: Process for tempering components
Inventor: GERDES HORST
IPC: C21D11/00
Filed: 1987-03-21
Abstract: The invention relates to a process for tempering components made of tool or heat-treatable steels to obtain a given hardness (desired hardness), in which the component is heated up (heating-up phase) to a given temperature (tempering temperature) and is kept at this tempering temperature for a given time (holding time), in order then to be cooled down again to the starting temperature (cooling-down phase). To improve the quality of the treated components and to improve the efficiency of the process, it is proposed, according to the invention, that firstly the material-specific dependence of the hardness on the main tempering parameter, which results from the tempering temperature and time, is determined with the aid of samples taken from various melts or from samples of the component to be tempered or its material analysis and a tempering characteristic is derived therefrom, and that during the tempering treatment the furnace or component temperature is constantly measured and from it, using the tempering characteristic mentioned, the respective hardness value is determined, which is used as control variable for the holding time.

Patent DE-3716035-A1 (DE)
Title: Method for separating solids from a product liquid in a centrifugal drum
Inventor: MACKEL WILFRIED DIPL ING
IPC: B03B5/32
Filed: 1987-05-14
Abstract: In the method, there is fed to the centrifugal drum, in addition to the product liquid, an auxiliary liquid whose relative density is at least as large as that of the product liquid but smaller than that of the solids. The product liquid and the auxiliary liquid are fed to the centrifugal drum in such a manner that a radially inner product liquid layer and an auxiliary liquid layer arranged concentrically with respect to the latter build up in the centrifugal drum. The solids separated from the product liquid layer must also pass through the auxiliary liquid layer before they can be regarded as completely separated. The position of the solid particles within the product liquid layer has only a small influence on their separation as they must pass completely through the preferably substantially thicker auxiliary liquid layer. By this means, a better grading effect in the separation of the solids is possible.
Patent DE-3721802-A1 (DE)
Inventor: RIESER MANFRED
IPC: E21C35/187
Filed: 1987-07-01
Abstract: The nozzle (10,11, Fig. 1) sprays cooling liquid for the bit 7 of a cutting head and comprises a bursting cap portion (16) (Fig. 2) connected with a housing (15). The cooling liquid normally flows centrally through a spring-biassed valve member (19) to a nozzle (17). If an excess liquid pressure is generated due to clogging of the nozzle (17), the valve opens and the sudden pressure rise within an annular chamber (25) results in bursting of the cap portion along its intended breaking areas (18) at a predetermined pressure. <IMAGE>
Patent DE-3725448-A1 (DE)
Title: Valve timing gear for varying valve lift and valve opening time
Inventor: BARTSCH RAINER
IPC: F01L13/00
Filed: 1987-07-31
Abstract: A two-armed adjusting lever (S) is in constant contact with the running surfaces of two cams (N1, N2), differing in their lift and overall lift duration and transmits the cam lifting movements by way of a pickup (ASt) to the valve. Spring-loaded tappets (F) increase the contact pressure of the adjusting lever (S) on the cams (N1, N2). A rotation of the control shaft (Sw), the crank pin (Kz) of which slides in the guide groove (Fü) of the adjusting lever (S), displaces the axis of rotation (D) of the adjusting lever (S) and thereby adjusts the lever arm ratio between the lifting action points (H1, H2) of the two cams (N1, N2) and the axis of rotation (D). The share of the lift of each individual cam in the valve lift varies, resulting in a stepless variation of the maximum valve lift and the valve opening time. This allows the valve timing and valve timing cross-sections to be adjusted to the requirements of different engine speeds and loads in internal combustion engines. The primary concern is to improve the torque/speed curve in order to increase the economy and ecological safety of an engine. <IMAGE>
Patent DE-3738745-A1 (DE)
Inventor: KAHLAU GERHARD
IPC: F16D57/04
Filed: 1987-11-14
Abstract: In a hydrodynamic retarder having at least two mutually opposite blade wheels (12, 14), which form a chargeable and dischargeable working space (16), the blading within a wheel is subdivided by sectors (A,B, Fig 2) into regions of one and the other direction of slant, that is on the rotor blade wheel and on the stator blade wheel. In this way, during the rotation of the rotor, zones of trailing blade position and zones of leading blade position alternate. This produces an equal operation of the retarder in both directions of rotation with a single rotor blade wheel, without additional structure or control outlay. To compensate for the resulting reduced average braking torque value, the profile diameter need only be increased slightly, since the power absorption increases proportionally to the 5th power of the diameter. <IMAGE>

Title: Oil-conveying device for an atomising oil burner
Inventor: NEUMANN FRANK ING GRAD
IPC: F23D11/28
Filed: 1988-01-08
Abstract: In an oil-conveying device for an atomising oil burner, having a nozzle stock which can be connected via a solenoid valve (4) to the flow of a pump (1) and has a nozzle shut-off valve (8) which is to be opened by the flow pressure, and a nozzle (9), to avoid continued spraying and dripping when the burner is switched off, a spring-loaded non-return valve (27) which opens towards the pump (1) and whose opening pressure is smaller than the opening pressure of the nozzle shut-off valve (8) is provided in a by-pass line (20, 25) arranged parallel to the solenoid valve (4).

Patent DE-3801647-A1 (DE)
Title: Method and device for testing an all-wheel-drive assembly
Inventor: GEISS NORBERT DIPL ING
IPC: G01M17/007
Filed: 1988-01-21
Abstract: The object of the invention is a method and a device for testing an all-wheel-drive assembly by means of simulation of drive states of the appertaining vehicle in an all-wheel test stand, in which the all-wheel-drive assembly is coupled to a front engine and in each case on the axle shafts to a rear engine. For each axle shaft, the axle shaft rotational speed is measured and compared with a control variable, which is determined from a driving speed taking into account a respectively preset curve radius for the appertaining wheel, to form a rotational speed difference. The longitudinal tyre force is determined from the rotational speed difference by means of a characteristic curve which establishes the longitudinal force on the tyre as a function of the rotational speed difference between the rotational speed of the tyre and the rotational speed corresponding to the driving speed. The difference of the moments acting on the wheel is formed from the longitudinal tyre force by comparing at least with the measured axle shaft moment. By integrating the difference and dividing by the moment of inertia of the wheel, the desired value of the rotational speed of the wheel is determined, and is compared with the actual value of the rotational speed of the wheel to form the control deviation, which loads the rear engine via a controller. <IMAGE>
