Abstract: 1,084,187. Safe load indicators for cranes. CARL SCHENK MASCHINENFABRIK G.m.b.H. July 19, 1965 [July 18, 1964], No. 30632/65. Heading B8B. [Also in Division G1] A safe load indicator for a crane has a circuit G which can be preset for the maximum safe load and which also measures the load on the crane. This circuit is connected to an instrument AW with a pointer which moves from its position of rest and sounds an alarm as soon as the actual load exceeds the preset safe load. An operational voltage Usp is applied across a bridge of strain guages D1-D4 and a point 3 is adjusted to zero voltage by a potentiometer P1 before a load is applied. The pointer actuates a contact N through a shaft 7 and a cam 8. By means of a resistance 10 a voltage Uh proportional to the maximum safe load is applied to the bridge circuit. A contact Z in a time-delay switch disconnects the voltage Uh after a certain delay. In a second embodiment, Fig. 2 (not shown), the contact Z is initially connected between a potentiometer P2, which is used to apply the voltage for the safe load, and the point 3. After the time delay has elapsed the contact Z switches over to the potentiometer P1 thereby cancelling the preset voltage so that the pointer indicates the true load. The contact N may be operated other than mechanically, e.g. photo-electrically or magnetically.

Abstract: 1,232,289. Variable-speed gear. B. L. G. RUAUD. 27 June, 1968, No. 30739/68. Heading F2D. A variable-speed planetary gear comprises an input carrier 2 carrying a planet assembly comprising two opposed elements 4, 5 having inclined vanes 14, 15 defining oppositely directed cups, the element 4 being braked by centrifugal force acting on a fluid medium, e.g. hydraulic or a powder, picked up by the element 4 from a container 12, to drive the output shaft 8, e.g. via a ring gear 7 and a pinion 6 fast with the element 4, the kinetic energy imparted to the fluid by the element 4 being utilized by the element 5, on which it impinges on leaving element 4, which element 5 (thus exerts a turning moment on the input shaft to provide regenerative driving. As shown, a pinion 9, fast with the element 5 meshes a ring gear 10 fast with a stationary casing 20. The hydraulic fluid is fed to the container 12, freely mounted on the carrier 2, by a pump 11 and is maintained at a constant level therein by an overflow 13. The pump also provides lubrication for the gears and shafts. The planet assembly is balanced by a mass 3 which may be replaced by one or more planet assemblies. The gears may be replaced by chains and pinions, belts and pulleys, or the ring gears may be replaced by sun gears meshing the pinions 6 and 9 through idlers. The elements 4, 5 may be half-toric with inclined flat or curved blades. The output shaft may be concentric with the input shaft. The planet wheel axis V-W may be non- parallel to the main axis X-Y.

Abstract: 1,234,574. Electrical signal transducers. ROBERT BOSCH G.m.b.H. Aug. 2, 1968 [Aug. 12, 1967], No. 36903/68. Heading G1N. [Also in Division H1] Apparatus for producing an alternating signal whose frequency is proportional to the speed of rotation of a shaft 13 Fig. 1 comprises an armature 12, with four equi-spaced poles 14, attached to the shaft, and located at one end of a longitudinally magnetized cylindrical magnet 11, flux from the other pole of the magnet being conveyed via plate 18 to a fixed yoke 19 also with four poles 15. Plate 18 and yoke 19 have matching projections 20, 21 between which is located a magnetosensitive semi-conductor element 17. When shaft 13 and armature 12 are rotating, the flux through element 17 is maximum each time the poles 14, 15 are in line, giving a large change in resistance which may be used to produce a corresponding change in voltage for initiating a cyclic switching action, e.g. for the ignition system of an I. C. engine. An alternative flux path is provided by a cup 24 and poles 23 to minimize flux leakage effects. The element 17 could alternatively be a Hall plate element.
