Title: North seeking gyroscope with servo circuit - disconnected in second phase when caging control circuit orients pendulum to north
Inventor: SCHULTZ PETER DR ING
IPC: G01C19/38
Filed: 1977-03-31
Abstract: The gyro has two degrees of freedom and a rotor mounted in a frame. A case rotatable about a vertical axis is shaped as a pendulum or mounted in one. The frame is mounted in it with its axis of rotation perpendicular to the rotor axis and at least approx. vertical. A servo circuit reduces, via a control element, the deviation of the case w.r.t. the frame. The gyro is quickly accelerated (first phase) to a position approx. in the north direction. In the second phase the servo circuit is disconnected and deviation between frame and case is eliminated by a caging control circuit. In the second phase the pendulum freely swings in its bearing, and a device receives a correction signal corresponding to the caging circuit balanced state.

Title: Conical reduction roller for metal rolling mill - has active formative surfaces of parabolic form and may have hyperbolic smoothing zones
Inventor: TUSCHY ECKHARD DR RER NAT
IPC: B21B13/00
Filed: 1977-05-26
Abstract: The metal-rolling-mill has truncated conical rollers for reducing long cylindrical pieces into a piece of lesser dia. and is suitable for both cold rolling and work on non-ferrous metals. The roller has active surfaces constituted of formative and smoothing zones, and the former are approx. parabolic. Each conical sector of the formative surface produces identical local rolling deformations, or deformations which reduce relative to the hardening of the metal. The rollers are disposed on oblique axies within a hollow shaft which is traversed axially by the workpiece. The rollers can be adjusted for position along their axies of rotation and are driven by satellite pinions. The satellite pinions turn about the axis of the workpiece and are themselves driven by a planetary pinion. The smoothing zones may assume the form of a technical hyperboloid, and each roller may include canals for the circulation of cooling fluid.
Patent DE-2726828-A1 (DE)
Title: Pattern data reading unit - has a light beam to register colours on pattern paper with discrimination of delicate tones for conversion to machine data
Inventor: MAURER GOTTFRIED
IPC: D03C17/06
Filed: 1977-06-14
Abstract: In mfg. a woven or knitted fabric with a complex pattern, a monitor registers and reads colour data from a pattern paper. The pattern paper contains at least two separate colours which are optically different from each other. The reader discriminates between the colours, and delivers an energy stream when a colour is registered. The energy representing a detected colour is passed through a number of filters, each with an individual mean frequency, so that the energy for the colour passes through at least two filters. The energy passing through a filter is converted into a special signal which is compared with preset tolerance bands. If the signal falls within the tolerance band this is signalled as data for reading by the machine working the fabric. The system allows discrimination of a wide range of colours and tones, so that delicate shades can be worked accurately into the fabric, partic. with Jacquards.

Title: Tractor hydraulic power lift system - has hydraulic ram with lock valve preventing leakage of fluid from ram and safety interlock valve controlling release of lock valve
Inventor: LEVINGTON HENRY JOHN
IPC: A01B63/10
Filed: 1978-06-23
Abstract: The hydraulic power lift system has a single acting hydraulic ram for raising the linkage connected to an implement. A manually operated valve controls fluid flow to and from the ram.
