Title: Safety cut=out for rotating machinery - has operating plunger in machine foot switches off current if foot lifts
Inventor: BARTH ERICH
IPC: D06F33/48
Filed: 1980-09-18
Abstract: A safety cut-out for rotating machinery such as a washing machine, centrifuge, etc., consists of a plunger housed in one or more of the machine feet which is depressed by the weight of the machine. In this position the plunger hinders the movement of a spring-loaded button in a power switch. Damaging vibration of the machine causes the foot to lift from the floor, allowing the plunger to project, releasing the switch button and cutting off the power. The action of the cut-out is non-specific, and is effective with any sort of vibration, whether caused by an unbalanced load, suspension system defects, faulty installation, etc., and can replace a number of specific fault-sensors.

Patent DE-3047644-A1 (DE)
Inventor: BLATTER JOHANN
IPC: H01H33/42
Filed: 1980-12-17
Abstract: A collar (10) is provided at at least one end of the drive rod (1'), which collar (10) has a coaxial threaded hole (11) in which a compression screw (32) of the operating rod (3) (which is coaxially coupled to the drive rod) is seated. The operating rod (3) has a shoulder (31) on which two half-shells (34) rest. A retaining ring (35) which is pulled towards the collar (10) by means of tensioning screws (37) which are screwed into the collar (10), rests on the spherical surfaces (340) of the half-shells (34). In consequence, the screws (37) prestress themselves and the compression screw (32) without play. The spherical nature of the surfaces (340) prevents bracing. For assembly, the retaining ring (35) can be pushed over the shoulder (31) and can be held by the half-shells (34) which are then attached. Assembly is thus simple. Because of the rotational symmetry of all parts, they can be produced precisely, economically and with low tolerances, by turning. <IMAGE>

Title: Labelling machine having a turntable
Inventor: ZEPF GEORG
IPC: B65C9/04
Filed: 1981-07-10
Abstract: A labelling machine having a turntable (6) possesses a sun wheel (25) which is rotatably mounted concentrically relative to this and into which engage planet wheels (26) connected to rotary plates (7) mounted in the turntable. The sun wheel is driven synchronously with the turntable via a change-wheel gear (29) with an adjustable rocker (28) and an exchangeable change wheel (40). The transmission ratio is designed in such a way that the labelling articles clamped on the rotary plates rotate at the desired angular speed in relation to the rotating turntable, so that, for example, an exact extraction of all-round labels from a stationary label container (11) directly by the previously glue-coated labelling articles is possible. As a result of an exchange of the change wheel and an adjustment of the rocker by means of a handwheel (31) and a threaded spindle (30), an exact change-over of the speed ratio between the turntable and the rotary plates to a different labelling-article diameter is possible quickly and easily. <IMAGE>
