Patent DE-2816424-A1 (DE)
Inventor: THADDEY KURT
IPC: B65C9/42
Filed: 1978-04-15
Abstract: In the transfer of a label, retained by means of a vacuum on the transfer device, to a body to be labelled, a periodically recurring variation in the vacuum between a high value in the presence of a label and a lower value after removal of the label occurs. One branch of a bridge (110) connected to a vacuum source is connected to the vacuum chamber (106) of the transfer device. A cylinder (116) in a cross-connection (115) of the bridge contains a piston (120) with a permanent magnet (121). When a label (101) is present above the suction holes (31) of the transfer device, the piston (120) is in the lower position and, after the removal of a label from the suction holes, moves into the upper position. A reed contact (123) next to the cylinder (116) is opened and closed under the influence of the permanent magnet (121) moving in oscillation. The absence of the actuation of the reed contact (123), taking place regularly during a fault-free labelling operation, can be utilised, together with other switching devices, for a luminous indication or for stopping the machine. <IMAGE>

Patent DE-2846619-A1 (DE)
Title: Changeover and parallel switching for power regulator transformers - using difference in switching stage settings to determine level of compensating current w.r.t. applied load
Inventor: HECHT SIEGFRIED DIPL ING
IPC: H02J3/38
Filed: 1978-10-26
Abstract: The changeover and parallel-switching method is for two regulator transformers whose primary voltage is connected to the common null-circuit i.e. over-voltage circuit. The secondary side supplies, via independent bus-bars, the galvanic, separate, independent networks at the same voltage level. In a first step, the switching stages of both transformers are set. The transformer, with the greater load, is tied down to the lower limb or the open terminal voltage, so that, as a result of the difference in the stage-settings, the magnitude or the compensating current is fixed. In a second step, the compensating current is fixed, by taking into account the loading or both transformers so that the max. permissible, total output of each of the transformers, even after parallel switching, is not exceeded. In a third stage, the expected and permissible compensation current values are compared, and if the former is to large or to small, the stage-setting is decreased or increased accordingly.
Patent DE-2847380-A1 (DE)
Title: Position regulator for pneumatic valve - has spiral spring for feedback of valve position acting on measuring membrane
Inventor: KEMMLER LOTHAR
IPC: F15C4/00
Filed: 1978-10-31
Abstract: The pressure operated position regulator (40) uses a signal spring (41) for monitoring the position of the valve, secured at the inner end to a shaft (42) extending from the end of a lever arm (38) coupled to the valve rod (31). The outer end (41") of the spring (41) acts directly on the movable part of the pressure measuring device for the position regulator, e.g. a measuring membrane (43) or spring bellows, so that the latter moves against the force of the spiral spring (41). Pref. the spring (41) is directly secured to a pressure measuring pin (45) fixed to the measuring membrane (43) at one end and acting on a lift plate (51) at the other end. This plate (51) cooperates with a release valve (52) which indirectly causes the valve to open.
Patent DE-2848025-A1 (DE)
Title: Thermal insulation for large pipe taking hot high-pressure gas - located internally and having temp. independent performance
Inventor: BUDKE JUERGEN DIPL PHYS DR
IPC: G21C11/08
Filed: 1978-11-06
Abstract: Large pipe carrying hot high-pressure gas as in a "High-Temperature" nuclear reactor has thermal insulation comprising lengths of coaxial graphite tube mounted internally. As claimed, circumferential grooves cut in each abutting pair of tube-ends together form a single chamber this being filled with a graphite ring whose inner and outer circumferences have alternately spaced circumferential slots each of depth exceeding half the ring radial thickness. Pref. the chamber and ring system penetrate the 2 abutting tube-ends to unequal depths. Only the portion of ring lying well into the deeper groove carries the slots. The abutment positions of adjacent tubes are axially displaced from each other. Elasticity provided by the system of slots in those graphite rings situated in the grooves prevents stress arising from tube interaction caused by thermal expansion. The intrinsic strength of the tubes is therefore available to withstand any sudden depressurisation of the system. This elasticity, and also that of the slotted interspace rings helps to restrict gas flow in the interspace over a range of temp. within which the insulation therefore remains effective.

A reinforcing bead can be formed on the sheet, over which this strip fits.
Patent DE-2854701-A1 (DE)
Inventor: HENTSCHEL MICHAEL DR ING
IPC: H02H3/253
Filed: 1978-12-18
Abstract: The heating is simulated in the circuit by the charging of at least one capacitor of a thermal model (L), the charging being controlled by the current consumption of the apparatus or of the machine. In order to simulate the heating of the apparatus or machine resulting from asymmetry in the supply to said apparatus or machine, the charging is controlled such that the charging current rises as a function of both the negative-sequence (IG) and positive-sequence (IM) components of the current consumption. The circuit preferably simulates the negative-sequence component (IG) approximately by forming a signal (T) which is proportional to the maximum amplitude difference (UG-UR) occurring between two phases of the current consumption. In consequence, it is made possible to produce a capacitor charging current which takes into account the additional heating of the apparatus or of the machine caused as a result of asymmetry in the current consumption. <IMAGE>

IPC: F16H3/64
Filed: 1979-01-25
Abstract: The method of interconnecting groups of machines in series, parallel, parallel/series, or series/parallel, arrangements can be used for mechanical, turbo-mechanical, or electro-mechanical drives, or combinations of these types of drive. The drive units can be gear units, turbo units or generators. The drive connections between them can be supported or unsupported so that torque is transferred between machines and used with auxiliary mechanisms so that braking forces can be applied by using hydraulic, pneumatic or combined control devices. Braking forces can be used to maintain a constant torque between machines. Drive conditions are given for cylindrical gearwheels, bevel wheels and turbo-mechanical drives.
