Title: Bitumen additives of acrylic copolymers with basic nitrogen cpds. - giving improved adhesion to mineral fillers
Inventor: NEUDOERFL PETER DIPL PHYS DR
IPC: C08L95/00
Filed: 1975-03-05
Abstract: Bitumen modifiers consisting of solid copolymers of (a) 3-20 wt % (meth)acrylic acid, (b) 3-20% unsat. polymerisable basic N cpd. with marked proton acceptor properties, (c) 30-94 wt % over 6C alkyl ester of (meth)acrylic acid, and (d) 0-50% one or more monomers with not more than one polymerisable C=C bond. mol.wt of the copolymers is 50000-500000. Due to hydrogen bonding in the additives, they give non-tacky brittle materials, which are easily pulverised, bandled and stored at room temp. The temp. interval between break pt. and softening pt. of bitumen compsns. is extended. Adhesion to mineral fillers, e.g. gravel, is improved and unaffected by water or moisture.

Title: Wheel-alignment equipment for motor vehicles - uses optical projection with universally adjustable mirrors for complete geometry check
Inventor: SCHMID JUERGEN
IPC: G01B11/275
Filed: 1975-05-17
Abstract: The measuring equipment comprises two projectors and adjustable mirrors, the projectors having three lenses arranged at 90 degree intervals in the horizontal plane. Each projector (25, 28) has adjustable clamps so that it may be aligned with the side of the body or chassis or the vehicle. The projectors are initially set up on each side of the vehicle at the centre line until eacc beam is self-collinated, one with the other (37, 38). Mirrors (29, 30) adjustable by universal pivots, are claped to each wheel of the common axle (23, 24). By adjustment of the mirrors in conjunction with various alignment marks and observation of angular displacement of the light beam against a scale, degree of toe-in, toe-out or camber angle can be determined.

Title: Fog signal circuit for ship - with several remote switches linked to master relay to give periodic signal
Inventor: HOLM BENGT LENNART
IPC: G08B3/10
Filed: 1975-07-02
Abstract: The fog signal of the ship is operated by a first relay which couples the signal to the supply voltage. The relay is operated by a second relay, or by a cam operated by a servo motor, to provide a periodic signal. A master relay operates as a holding relay to connect the motor to the supply voltage until the operating control is activated again. In order to provide a remote control for manual overide from different sites on the ship, a number of switches are coupled in parallel to a third relay which operates the signal once every time the remote controls are activated. Each remove control requires only one control line to the relay, with the other side of the switch to the supply line.

Title: Test installation torque and speed control - in system for multi-machine testing providing torque and speed regulator decoupling
Inventor: THUN HANS-JUERGEN V DIPL ING
IPC: G01M13/02
Filed: 1975-08-09
Abstract: A system for regulating the rotation speed and torque in a multi-machine test installation is designed for independent operation of the speed and torque regulation circuits. The installation operates with a machine coupled to a test piece and with drive moment proportional control parameters applied to the regulating circuits. The coupling between the circuits is strongly reduced by using good system damping. This, in turn, enables circuits of improved dynamic characteristics to be used. The speed regulating signal is input to the circuit governing the torque via a decoupling circuit. Additional electrical damping signals are derived from the machine speeds and fed to one or all of the governors with suitable amplification and phase lag. Phase advance torque control signals derived from the desired torque value are also used as an input to the regulating circuits.
