Patent DE-4131514-A1 (DE)
Inventor: KIRN MANFRED
IPC: B25F5/00
Filed: 1991-09-21
Abstract: Described is a hand-held power tool, in particular an angle grinder (1), fitted with a spindle brake (21), the tool having a spindle (7, 67) on which a disc-shaped attachment (33, 83) is gripped between an inner flange (29, 79) and an outer flange (31, 81).

Title: Non-carcinogenic cationic inorganic adsorbents to replace chrysotile asbestos - comprise non-fibrous synthetic serpentine made by hydrothermal synthesis under mild conditions
Inventor: GEYER STEFAN
IPC: B01J20/04
Filed: 1991-11-07
Abstract: Cationic inorganic adsorbent comprises synthetic serpentine 3MgO.2SiO2.2H2O having only a low degree of ordering, made by hydrothermal synthesis at 150-250 deg. C and 0.5-4.0 MPa.

Patent DE-4210273-A1 (DE)
Title: Power driver, for nut running, with torque limiting function - uses comparison of motor load with preset reference as input to phase gate control circuit of motor
Inventor: FRIEDRICH HANS-PETER DIPL ING
IPC: B25B23/147
Filed: 1992-03-28
Abstract: The torque-limiting power driver has an electric motor with gearbox whose output shaft connects to a socket head. A potentiometer is used for adjusting the torque limit and this is linked to a triac or thyristor for phase gate control of the motor current. The current phase angle is controlled by the load on the motor and fluctuations in the supply voltage. The cut-out switch is controlled by a circuit comparing the torque limit reference voltage (derived from the supply voltage by a potentiometer) and a voltage corresp. to the prevailing load (derived from a low ohmage resistor in the motor supply leads). The latter voltage signal is delayed through a low-pass filter to suppress high frequency peaks. ADVANTAGE - Switching peaks, e.g. when switching on at mains, do not affect torque limiting function and momentary load fluctuations are bypassed.

Title: Decorative faced sprue-free moulding - produced by placing embossed film across mould, closing it, injecting thermoplastic shot behind film and oscillating to break off sprue
Inventor: BOECKLEIN MICHAEL
IPC: B29C45/38
Filed: 1992-08-28
Abstract: A decorative plastic article is produced with an embossed film. The embossed film is placed between two mould tools which are then brought together to form the mould cavity and to grip the film between them. A shot of plastic material is injected into the cavity through at least one runner in one of the tools. This shot is allowed to harden to a correspondingly decorative prod., after which the mould is opened and the prod. is ejected. Before the moulding has set hard, however, the sprue formed is broken off. ADVANTAGE - The procedure eliminates the formation of flash or of rejects when the sprue is broken off

Title: Hydraulic pressure reducing valve with pilot stage and main spool - uses pilot to provide compensating action when valve responds to sudden fall in inlet pressure
Inventor: RAUSCH JUERGEN
IPC: B60T8/44
Filed: 1992-11-24
Abstract: A hydraulic pressure reducing valve has a pressure inlet (56) and outlet (42), together with a control connection (41). At one end of the valve a pilot stage (50) has a pin (55) that displaces a ball (26) relative to a bush (16) to determine the flow to a main stepped spool (22). The spool responds to the control input and output pressure on an annular area. If there is a sudden fall in the inlet pressure, the pilot stage responds to compensate for the change in force and provides a reduction in the noise generated by the sudden closure. ADVANTAGE - Provides damping of noise when spool responds to sudden drop in inlet pressure.
Patent DE-4243650-A1 (DE)
Title: Chuck for holding screwdriver bit
Inventor: SCHMIDT ULRICH
IPC: B25B23/00
Filed: 1992-12-23
Abstract: The hexagonal end of the screwdriver bit (4) is held in the corresponding bore (6) of a bush (2). Sliding on the bush is a sleeve (5) with an internal conical section (12) which bears on a ball (9) housed in a radial hole (8) of the bush.Because the conical section (12) opens towards the mouth of the chuck, downward movement of the sleeve (5) under the action of a compression spring (11) automatically forces the ball against notches (19) of the screwdriver bit and retains it in place. The bit is released by pulling the sleeve upwards against the force of the spring.

Title: Settling apparatus for separating a mixture of materials, in particular of solid particles from liquids
Inventor: KNETSCH REINHARD
IPC: B01D21/00
Filed: 1993-01-26
Abstract: A settling apparatus, which is effective as an inclined clarifier or lamella clarifier for separating a mixture of materials, in particular solid particles from liquids, is explained and claimed, wherein a multiplicity of lamellae (3) are arranged at a mutual spacing and in an inclined position in a tank or basin (2) which can be charged with the suspension, two adjacent lamellae (3) in each case defining a chamber (4) between them, in which the upper side of the back lamella (3) in each case is effective as a settling surface for the solids particles. In order to be able to overcome an undesired plugging or blocking of the chambers (4), in particular in the region of the bottom thickening zone, the lamellae (3) are accommodated in the tank or basin (2) in an adjustably inclined position. In this case, it is advantageous that a divergent enlargement of the chambers (4) between the lower ends of the lamellae (3) is coupled with the setting of a steep inclined position for the lamellae (3). <IMAGE>
