Patent DE-3627962-A1 (DE)
Title: Rotary internal combustion engine
Inventor: JAUCH KURT
IPC: F02B55/14
Filed: 1986-08-18
Abstract: In a housing (1; 2), which contains a rotary piston compressor and a rotary piston engine, groups each of three cylinder chambers (3-5, 6-8; 20-22, 23-25) are formed, overlapping one another in pairs, and each with a shaft (18, 19; 32, 33) passing through it. Three rotary pistons (12-14, 15-17; 26-28, 29-31), of which the middle rotary piston is in each case offset by 180 DEG  in relation to the two outer rotary pistons, are fixed on each of the shafts (18, 19; 32, 33). Sealing sleeves (37, 38) are axially supported side by side in recesses of the rotary pistons (12-14, 15-17; 26-28, 29-31) in such a way that two rotary pistons fixed on the opposing shaft and turned by 180 DEG  counter to one another are capable of rolling on each sealing sleeve, forming a seal. The result of this is that the sealing sleeves (37, 38) in operation constantly rotate at the same circumferential speed as the rotary pistons (12-14, 15-17; 26-28, 29-31). The wear on the circumferential surfaces of the sealing sleeves (37, 38) and rotary pistons (12-14, 15-17; 26-28, 29-31) rolling on one another is thereby kept to a minimum. <IMAGE>

IPC: B23F19/06
Filed: 1986-10-23
Abstract: A gear-dressing machine contains a device producing crowning as well as a tapering device (31), a gear-shaped tool (36) and the gear (35) to be machined being displaced parallel to the respective axes in order to dress the gear, specifically in a state in which the engagement of the tool (36) on the gear takes place with crossed axes. The gear-dressing machine contains a device which rotates about a perpendicular axis of the machine in order to set the tool at the predetermined angle of crossing as well as two drive devices (25 and 41) in order to drive the tool and the gear independently of one another at right angles to the perpendicular direction as well as in respective axial directions in which both axes of the two drive devices are in each case orientated at right angles to one another in order to displace the tool and the gear in a desired direction. In such gear-dressing machines, a rotating mechanism allocated to a table carrying the gear is unnecessary. Nor is actuation necessary for exchanging parts if a change in the movement of the table is to take place. <IMAGE>

Title: Circuit arrangement for protecting electronic apparatuses against overloading
Inventor: BRAHMS MARTIN DIPL ING
IPC: H02H9/02
Filed: 1986-12-13
Abstract: A circuit arrangement is specified for protecting electronic apparatuses which are supplied from a DC voltage source and to which a connecting line (lead, cable) (ASL) is connected. A transistor (T2) is provided as the current-limiting element, in order to limit the current in the event of an overload on the connecting line (ASL). The transistor (T2) is switched off and on again at periodic intervals, when it is in its current-limiting state, by means of a swept-voltage generator (K). In normal operation of the circuit arrangement, the swept-voltage generator (K) does not function. By correct dimensioning of a diode (D2), the time in which the transistor (T2) is switched off can be set to be large in comparison with the time in which it acts as a current limiter. Excessive heating of the transistor (T2) is thus avoided. <IMAGE>

Title: Data processing system with a standard sequential circuit and at least one special sequential circuit
Inventor: BLOCK SIEGFRIED DIPL ING
IPC: G06F9/318
Filed: 1987-04-07
Abstract: In a programmable data processing system with a main sequential circuit (LSW) and at least one special sequential circuit (SSW), the appropriate sequential circuit (LSW, SSW) is activated by a switching network (SN), which is connected in series before the sequential circuits and distributes the current instruction (B1, B2, B3, BI, BII, BIII) to the relevant sequential circuit. For this purpose, the switching network (SN) receives a switching code (SK), which can be in the form of a binary word which is assigned to every instruction or the start of a subset of instructions. The switching code (SK) can also be in the form of a separate instruction which is stored within the program. The switching network (SN) can also be implemented so that it distributes the instructions without an additional switching code when it recognises the whole set of instructions. The program memory (PS) is only addressed by the main sequential circuit (LSW), to which an auxiliary instruction (HB1, HB2, HB3) is assigned while the special sequential circuit (SSW) is working, so that the instruction counter (BZ) of the main sequential circuit (LSW) is incremented to the appropriate state. <IMAGE>

Title: Non-ageing thermo-element
Inventor: KOERTVELYESSY LASZLO DIPL PHYS
IPC: H01L35/20
Filed: 1987-06-13
Abstract: The novel thermo-element on a nickel base contains a relatively large amount of chromium in both thermo-wires. The known non-noble-metal thermo-elements (e.g. iron/cupro-nickel, nickel-chromium/nickel, nickel-chromium-silicon/nickel-silicon) have a relatively high degree of ageing. The thermo-wires of the thermo-element according to the invention also age at high temperature but, surprisingly, the thermo-element itself does not. The negative thermo-wire is thicker than the positive. The novel thermo-element can, in a temperature range, imitate the thermo-electric voltage of any other thermo-element.
