Title: Selective voltage or transmission level meter - has two rectifiers each comprising two push-pull modulators, and differential transformer
Inventor: SCHLOSSER KARL ING GRAD
IPC: G01R19/00
Filed: 1977-01-18
Abstract: In addition to a measurement signal (UM, fM) two carrier signals shifted w.r.t. each other by 90 deg., and at a specified rational frequency relation to the measurement signal, are applied to a first controlled rectifier unit consisting of two push-pull modulators. Output d.c. signals are of the form of UM cos (phi) and UM sin (phi) and are applied together with two further carrier signals U cos (omega)t, and U sin (omega)t, to a second controlled rectifier unit, consisting of two push-pull modulators. It carries out a vectorial addition. A differential transformer is connected to the output of one of the push-pull modulators in the second rectifier, and delivers a signal whose amplitude is proportional to the vector UM.

Title: Batched article packing machine - has dividers forming batches from article column coupled by mechanism to haulage chain
Inventor: KETTNER MAX
IPC: B65B35/44
Filed: 1977-03-17
Abstract: The packing machine suitable for bottles is for a large number of similar articles each with a stand surface, these being delivered by a conveyer continuously in the lengthwise direction of the column into which they are formed. A grouping device removes a set number of articles at a time from the top of the column for delivery in a batch in the direction of column movement for further processing. This device has dividers (21) spaced apart for the amt. of a batch length and running in synchronism with the further processing mechanism, engaging between the articles in the column and hauled by an endless chain.

Title: Grinding machine for spherical valve parts - uses cup grinding wheels intersecting axis of blank for constant setting
Inventor: THIELENHAUS ERNST
IPC: B24B11/00
Filed: 1977-07-15
Abstract: The grinding machine is used for grinding spherical closure elements of large diameter for a valve. The sphere blank is clamped along a dia. and rotated. High quality finish without chatter marks is obtained even if the blank has wide roundness and surface tolerances. The spherical blank is stripped in a first operation by a cup grinding wheel. The axis of this grinding wheel intersects at right angles, in plan view, the clamping axis. These axes are, however, staggered. The stripped blank is subsequently machined, in the same setting, with another cup grinding wheel whose axis forms true intersection with the clamping axis of the blank. The relative displacement of the workpiece and grinding wheel axes are carried out by swivelling and parallel displacement.
