Patent DE-2718774-A1 (DE)
Title: Speed control for rotating cam - applies at least one intermediate speed control variable to drive at each change point to continuous working
Inventor: YAMADA TAKURO
IPC: B23Q15/10
Filed: 1977-04-27
Abstract: The drive for the object concerned, e.g. cam, is controlled by specified, stepped control variables at the objects specified angular positions. The method is intended for grinding cams, curves etc. At least one intermediate speed control variable is applied to the drive at each change-over point between different speeds, so that the object is driven at a speed between that before and after the point of change, and the object speed changes continuously without jerks. The drive for the object, e.g. a servo-motor, is determined at first by the rotational angle position w.r.t. a starting position.

Title: Phase locked loop as frequency or phase reference - compares oscillator output with output of resonator which has large field to give infinite negative phase slope characteristic
Inventor: BRANDELIK ALEXANDER DIPL ING D
IPC: H03L7/04
Filed: 1977-05-05
Abstract: The phase locked loop, as a frequency or phase reference, has an oscillator (2) whose output power is divided by a distributor (4) and passed via two HF cables to a resonator (1) and to the negative input of a phase detector (11). The resonator's output is connected to the phase detector's positive input. The phase detector's output controls the oscillator. The electromagnetic field in the resonator is large enough to degenerate the resonator's phase characteristics sufficiently to give a region of almost infinitely large negative phase slope.

Title: Resection surgical laser appts. - has organ clamping jaws with slot and groove reflecting laser beam
Inventor: MALYSCHEV BORIS NIKOLAEVITSCH
IPC: B23K26/10
Filed: 1977-05-17
Abstract: The surgical apparatus has a laser light source at the input end of a light conductor, whose output end has a collector lens. Clamping jaws (2, 3) of material impermeable to laser beams, compress the walls of a hollow organ (4) of a human being or animal from opposite sides along a line. A slide, also impermeable to laser beams (11), travels along a guide, and carries the outlet end of the light conductor (12) with collector lens (13). A slot is formed in one of the jaws along the line for the laser beam to reach the compressed organ, its walls reflecting the beam to a high degree. There is a groove in the other jaw opposite the slot, also reflecting and diffusing the beam. When the organ is compressed, the slot walls, groove and slide form a closed passage for the beam to its compressed part.

Title: Food pressure cooking - with initial program control of cooker outlet value for uniform temp. distribution
Inventor: JOENSSON NILS BERTIL
IPC: A23L5/10
Filed: 1978-01-14
Abstract: In a process for the treatment of food in a pressure cooker, steam is introduced from a steam generator into the cooker in which an outlet valve is kept open for a certain initial period. Depending on the kind of cooking process the valve is kept open continuously for a period of 2 min. or in pulses for a period of 3 min. This removes the air, which is present in the pressure cooker, in the shortest time and with the minimum energy consumption. It ensures a very uniform temp. distribution in the pressure cooker.

Title: Mould cores for moulding hollow rubber articles - with pneumatic disengagement from the static part of core mandrel
IPC: B29C45/43
Filed: 1978-07-21
Abstract: The core mandrel of a mould for making hollow mouldings from elastic material comprises two concentric hollow bodies shaped so that the smaller can more relative to the larger subjected to limits imposed by a conic seat and by a static head which limits the axial parting of the core pieces, e.g. by stopping a lip at the end of the base in the mobile core. The mobile core has an external lip which engages the end of the moulding. As the mobile core is shifted by pneumatic pressure, the moulding is subjected to tension and and then to internal pneumatic pressure via the parting plane of the cores, to ease disengagement of the moulding from the static mandrel. Arrangement is esp. suitable for making bellows or other articles with undulating wall profiles.
Patent DE-2833914-A1 (DE)
Inventor: GREUBEL WALDEMAR
IPC: F21K2/00
Filed: 1978-08-02
Abstract: A light-collecting device in the form of, for example, a rectangularly-shaped body having a so-called "fluorescent plate" with at least one light-exit window is comprised of a solid polymerized synthetic carrier material, such as a polyacrylate, a polymethacrylate, a polystyrene or copolymers thereof, containing fluorescing particles therein which have finite dipole moments with different values in the basic and in the excited state and containing a polar organic additive, such as a high-boiling polar solvent, for example, an aliphatic or aromatic alcohol, a nitrile or an ionogenic or non-ionogenic soap, with the fluorescing particles and additive being substantially uniformly distributed throughout such carrier material. The additive creates an environment with an orientating polarization about the fluorescent particles whereby the environment can re-orientate so-quickly that it achieves its thermodynamic equilibrium substantially completely during the existence of the excited state in the fluorescing particles and tends to suppress the disruptive self-absorption of light within the fluorescent plate. Such self-absorption originates from a partial overlap of the emission spectrum with the absorption spectrum of the fluorescing particles. The additive can be dissolved in the synthetic carrier material or can be chemically linked therewith and the so-attained system can be injection moulded, extruded or cast into a desired body form. The disclosed device is useful as a solar collector, an optical indicia transmitter or an image brightener for passive displays.
