Title: Axial thrust apparatus with power spindle - has tubular ram surrounding spindle with free end connected to slipping clutch
Inventor: BETZING VOLKER
IPC: F16D7/02
Filed: 1973-12-21
Abstract: The particular design is a position control apparatus using a ball bearing race collar. The tubular ram fits in a bearing bracket. The slipping clutch is designed with a conical surface and the secondary part of the spindle has an internal cone at its end.

Title: Gantry crane for ship - having transverse beams on gantry to extend range of crane
Inventor: RAU KURT
IPC: B66C19/00
Filed: 1974-02-13
Abstract: The gantry crane has a control console travelling on a support beam across the ship. Two arms are mounted transversely to the beam, i.e. along the longitudinal axis of the ship with lifting tackle at each end. This enables the load to be lifted from the side of the beam, giving the crane more range. Also the load can be swung past the side supports onto extending sections of the beam to drop them over the side of the ship. The gantry requires no swivelling cranes and is thus a strong, rigid structure. The control console is duplicated on the other side of the beam.

Title: Road marking spray gun appts. - has heating jacket, fueled by oil, melting resinous thermoplastic from its powder form
Inventor: HARDING JOHN
IPC: E01C23/22
Filed: 1974-04-11
Abstract: The spray gun feeds the liquid material to be sprayed by feeding solid material into an endless conveying path, circulating the material around the path while the material is being heated to a predetermined temperature, discharging some of the heated material to the spray gun, and feeding further solid material into the conveying path. Apparatus suitable for spraying marking material onto road or other surfaces is described for carrying out the above method. Alternatively the hot liquid material may be intermittently discharged from the conveying path when, for example, it is desired to apply dash lines in the centre of the road surface. In this case the further solid material is also fed intermittently into the conveying path in timed relation and in a proportionate quantity to the liquid material discharged.

Title: Acceleration circuit for HF stepper motor - two branches with dissimilar time constants, one controlling other
Inventor: ARNOLD WERNER F ING GRAD
IPC: G05B19/416
Filed: 1974-05-07
Abstract: Stepping motors operating at pulse frequencies of the order of 6kHz, employ a circuit to overcome the braking effects which can be caused by mechanical resonances, diminishing these resonances by controlled acceleration. A first RC circuit (1, 2) has a time constant longer than that of the second circuit (3, 4, 5). The first circuit controls the resistance (5) of the second, typically by acting on a variable resistance element (6), for example a field effect transistor. The charging time of the second circuit is thus varied. The second circuit is connected to a level detector which switches to discharge the second capacitor (3) and thus produces an output of increasing frequency to accelerate the motor. A similar process may be used for retardation.
