Title: Slip-free follower control of stepping motors - with signals from nominal-valve indicator conveyed to motor
Inventor: KIRSCHBAUM BERTHOLD
IPC: G05B19/23
Filed: 1973-09-08
Abstract: In the method, the electrical signals produced by a position indicator detecting the movement and position of the stepping motor are delivered to a comparator. The difference between these electrical signals and the signals produced by the nominal-value indicator is used as a position correcting value for the movement of the stepping motor. The nominal-value and position indicators produce pulse trains, each of which is counted in a counter and whose amounts are subtracted from one another. The difference value is used as a correcting value to control the stepping motor.

Title: Optical-sonic reproduction record - transparent disc has mechanical recording on one side and optic recording on reverse
Inventor: THIELE HEINZ
IPC: G11B7/24
Filed: 1973-09-18
Abstract: Disc shaped optic/sonic records have adaptors to line up with the reproducing apparatus. One side of the disc has trace for mechanical and reverse side has fine optical trace for laser beam recording-reproducing. The record is transparent at least in the video information carrying section and its thickness is sufficient not to be affected by the mechanical trace on the other side. The optic side is covered with a reflecting surface. The information recorded and the speed of recording (1500-1800 r.p.m.) on the two sides is similar but not identical. The two types of recording can be carried out on two separate discs which are then joined with recorded faces up, one on top of the other. The process of recording is performed in one working cycle one side first than the other.
Patent DE-2351127-A1 (DE)
Title: Voltage regulator for high voltages - reduces cost by dispensing with high voltage inductor
Inventor: WIESMUELLER SIEGFRIED
IPC: H02M3/337
Filed: 1973-10-11
Abstract: The circuit controls the voltage across a varying load by feedback control of the mark-space ration of switches. The switches run at several kHz and the regulated output voltage is smoothed by a capacitor across the output terminals. One of the switches connects the voltage source through a resistor across this capacitor and the other connects discharge resistor across it. The switches may be transistors or other semiconductor devices and one is always closed when the other is open. From a reference voltage and the output voltage a comparator generates an error signal which controls the threshold level at which the switches are operated by a triangular waveform. Thus the charging switch is closed longer with a heavy load condition and vice versa.

Title: Rotary switch system for transformer stage switch - reduces contact sparking by grading fine winding tappings and bridging
Inventor: WIDMANN WERNER
IPC: H01F29/04
Filed: 1973-11-30
Abstract: The rotary switch system, for a transformer stage switch, has the fine winding stage tappings coupled over separate resistors to the rotary selection switch fixed contact studs. The ends of the winding are connected directly to the switch end contact studs. The switch lever has a hammer-head end that can bridge adjacent contacts.

Title: Driving mechanism for perpetual calendar - gives automatic data indication except for february, which requires adjustment by hand
Inventor: SATO REIJI
IPC: G09D3/06
Filed: 1974-01-08
Abstract: The actuating arrangement for a perpetual calendar uses a smaller number of parts and is more simply constructed than comparable mechanisms. The mechanism drive shaft holds a cog wheel, a data adjustment wheel, a month adjustment wheel, and a cog which engages with a pinion wheel. The periphery of the date wheel is divided uniformly into 31 sections, that representing the 30th day having a concave surface. The month wheel is rotated 1/122 or 1/24 of a full revolution ech month by a coupling. Its periphery is subdivided uniformly into 12 or 24 sections, each section corresponding to a month with 30 days having a concave surface. A lever pressing against both date and month wheels drops into the concave surfaces of both wheels when they coincide, so that a trip wheel which is normally moved by one cog each day is moved two cogs.

Title: Bedding material tamping unit for railway track - has two sets of tamping heads arranged behind one another and operated cyclically
Inventor: STEWART JOHN KENNETH
IPC: E01B27/17
Filed: 1974-01-22
Abstract: The tamping machine travels along the railway track and the sets of tamping heads operate in such a way that while the first head executes its working cycle, the second head is moved on the machine frame towards the fist head. While this second head executes its working cycle, the first head is moved along the track away from the second head whereby the tamping cycles overlap one another with a phase displacement of 180 deg. This operational design enables the working speed of the machine to be increased even though the sleepers may not be evenly separated from one another.
