Patent DE-4116202-A1 (DE)
Title: Driver bearing for electric power tool e.g. circular saw - holds tool so there is no play in axial or radial direction using pressure screws
Inventor: RAICHLE DIETER
IPC: F16C25/06
Filed: 1991-05-17
Abstract: The axial bearing (12) drives an electromotor (1) via a tool shaft (4) to which, e.g. a saw-blade (5), is attached. The shaft is located in a sleeve (6) and a radial bearing (7). The latter is axially movably located in a bearing seat (9) of a driver flange (10) connected to the housing (11). An axial needle bearing (12) between the cog (3) and the housing provides a rigid play-free seating of the shaft in the axial direction. Three bores (14) in the flange in which compression screws are screwed act on the radial bearing and press it in the direction of the needle bearing (12). This eliminates play in the radial bearing and safely prevents running of the saw-blade.

Title: Current limit circuit for electric motor pref. controlled by switching transistor - has at least one barrier resistance connected in series with motor winding to limit current to value compatible with transistor
Inventor: MENGE EBERHARD DIPL ING
IPC: H02H9/00
Filed: 1991-06-08
Abstract: Each series resistance (4, 5) is bridged by a thyristor (6, 7) which is switched on at a sufficiently high motor r.p.m. A voltage, rising with the motor r.p.m. and supplied to the gate of the thyristor, is produced either as a voltage difference tapped at the motor winding or by means of an induction coil (11) arranged on the stator winding (1). With an arrangement of several series resistances before the gates of the thyristors bridging them; voltage dependent semiconductors in the form of Zener diodes (18, 19) are so arranged, as regards voltage value or number connected in series, that the individual thyristors are switched on consecutively as a stepped circuit as motor r.p.m. increases. The motor is connected via. a full-wave rectifier to an AC so that, in both current paths of the rectifier, at least one series resistance is connected to the thyristor bridging it. ADVANTAGE - Motor current loads switching transistor at start, yet also limits this with certainty during operation. Switching transistor is thus not loaded and more robust thyristors take the load.

Patent DE-4135285-A1 (DE)
Inventor: HAUNER FRANZ DIPL ING DR
IPC: H01H11/04
Filed: 1991-10-25
Abstract: Especially in the case of contact layers made of a silver-metal oxide (AgMeO)-based material whose backside is provided with hard solder, it has been observed that the hard solder may indesirably ascend to the contact surfaces during hard soldering on a contact substrate. This is explained by the heat produced during hard soldering. According to the invention, the wettability of the side surfaces of the contact layers is reduced in order to prevent the hard solder from ascending to the printed circuit surface. Preferably, metal oxides are inserted for this purpose into the surfaces of the contact layers. In the case of silver-metal oxide (AgMeO)-based contact layers, metal oxides that are already available in the material as active elements are preferably used.

Title: Moulding shaped parts made of porcelain - using mould made of open-pored porcelain which can bind reversible water of crystallisation, further releasing it at corresp. temp.
Inventor: GRIGARCZIK GUNTHER
IPC: B28B7/34
Filed: 1992-01-08
Abstract: The mould is made of open-pored porcelain which can bind reversible water of crystallisation and further release it at corresp temp. During the moulding process the water present in the slip is rapidly withdrawn by capillary effect and by binding of water of crystallisation. After the moulding of the residual slip a rapid shrinkage occurs and after moulding the mould is passed through a microwave or other heat source, whereby the water of crystallisation is further driven out rapidly. USE/ADVANTAGE - For the structure of effective moulding equipment for thin and thick-walled porcelain piece strengths.

Abstract: In a CNC-machine having at least one main spindle (17) and a tailstock that can be driven by an electric motor (12) and that carries a clamping tool (18), i.e. a centre or a back spindle, a position limit is predetermined for the clamping tool, at which the part of the latter nearest to the workpiece (11) would lie within said workpiece. The clamping tool (18) is then driven in the direction of the position limit, at the same time as the force generated by the electric motor (12) or its torque is continuously monitored. The torque is limited to a maximum value preset in order to generate a desired holding force between the clamping tool (18) and the workpiece (11).

Title: Fuse monitoring method for power supply network - monitoring current variations in current converter secondary windings of individual phases and comparing with reference variations
Inventor: TROTT JOSEF DR
IPC: G01R31/02
Filed: 1992-03-27
Abstract: The fuse monitoring method involves continuously measurement of the current variations in the secondary windings (14-16) of the individual phases of a three-phase current converter (13) at time intervals.
