Title: Sliver drawing and collection unit - has monitored sliver store to control transport speed for sliver consistency
Inventor: SCHMID REINHOLD
IPC: D01H5/32
Filed: 1980-08-20
Abstract: A sliver store is located between the transport roller(s) and the collection point for the slivers being brought together to be drawn and laid together. The common drive for the transport rollers is controlled to give a higher speed when the store volume drops, and to reduce speed when the volume rises. The monitors, connected to a maximum/minimum switch, are in the form of opto-electronic or inductive or capacitative proximity switches to register the ends of the loops of sliver stored in variable lengths. Two energy sources are used for the drive to give a basic loading and an additional loading under separate control through a control channel. The additional loading is provided by an electro-motor with a controlled rotary speed, while the main motor for the basic loading powers the complete assembly. The system prevents the development of irregularities in the sliver on either side of the collection point, so that a consistent sliver is developed as an end product.

Patent DE-3103146-A1 (DE)
Title: Device for, in particular three-dimensional, measurement and/or marking off and/or scanning of workpieces
Inventor: KNOBLOCH ULRICH
IPC: B23Q11/00
Filed: 1981-01-30
Abstract: A three dimensional measuring, marking-off and/or scanning device is proposed whose column, which is fixed on the lower carriage and extends vertically, has a compound rest, which can be displaced on said column and has a transverse arm which can be displaced transversely relative to said compound rest. The column is braced with respect to the carriage by means of a strut which leads from the carriage to the column head and is mounted there adjustably by means of nuts which acts on the head part of the head plate. There is a thrust bearing in each case in the force path between the head part and the nut. Upon tightening of the nuts and adjustment of the unloading of the column by the strut, no reaction forces are guided onto the head part which could entail torsional stressing of the column. The measurement accuracy of the device is thereby increased. The transverse arm is seated with a lever arm at a distance from the centre of the column and therefore of itself causes no torsional loading of the column. For the purpose of compensation, the column is pretwisted to a desired extent with respect to the strut by means of a fork. The fork is seated on the strut in a manner secure against rotation. A fixed stop projects between the two fork limbs and is held firmly on the head part of the column. The fixed stop is spaced from the centre of the column. For the purpose of adjustment, each fork limb contains a threaded pin which presses against the fixed stop.

Title: Push-button switch
Inventor: NEUMANN PETER DIPL ING
IPC: H01H1/20
Filed: 1982-04-07
Abstract: The invention relates to a push-button switch whose push button, which has a cylindrical basic shape, operates a rotating and switching device, a switching pin which rotates in steps and assumes a high position on the one hand and a low position on the other hand supports an annular contact which is loaded by a spring towards the free end and connects two contacts provided in the housing to one another, or separates them from one another, depending on the position of the switching pin. It is endeavoured in the case of such a switch that one and the same switching positions are avoided and hence that no material overloads occur as a result of erosion on the contact means. This is achieved when a drive pin (cf. 10) is provided between the ring contact (7) and the switching pin (6) which switches onwards by, for example, 45 DEG  when the button is pressed (cf. 4, 5). <IMAGE>

Patent DE-3219853-A1 (DE)
Title: Multiple switch, especially an ignition/starter switch for motor vehicles
Inventor: MERTEN GUENTER
IPC: H01H1/16
Filed: 1982-05-27
Abstract: The invention relates to a multiple switch, which is especially suitable as an ignition/starter switch for motor vehicles. A central contact (2) can be connected by means of contact links (4.1, 4.2) to a plurality of outer stationary contacts (3a, 3b, 3c, 3d), in an alternating switching sequence. Each contact link is in permenant contact with the central contact (2), by means of a stamped contact surface (4b), and, at the other end, has a freely rotatable contact roller (4c) for making contact with the stationary contacts (3a, 3b, 3c, 3d). The stationary contacts are partially enclosed on one or both sides by control tracks (5a, 5b, 5c) for the contact rollers (4c) of the contact links (4.1, 4.2). No circuit making or breaking occurs on the central contact (2) and on the transition from the contact shaft to the contact roller (4c), and hence also no errosion. The electrical stress occurs mainly on the external circumference of the contact rollers (4c) and on the stationary contacts. This structure ensures excellent quality and a clean switching behaviour with a simple and space-saving construction. <IMAGE>
