Patent DE-3000800-A1 (DE)
Title: Static converter for frequency reduction - uses two antiparallel current gates for each phase
Inventor: IOVY RICHHARD KLAUS DR ING
IPC: H02M5/27
Filed: 1980-01-11
Abstract: The static converter reduces frequency by a non-integral number in the range 1 to 0.5. The output frequency is related to the input frequency by a specified equation involving the number of phases of the supplying transformer. The number of phases of the transformer determines the ratio between the output and input frequencies. Each phase has two antiparallel current gates. The gates may comprise thyristors each with two antiparallel diodes. The converter may be used to change, e.g. 60 Hz to 50 Hz.

Title: Locking device for fire escape or telescopic frame - has cord operated tilting plates controlling arms locking against adjacent sections
IPC: B66B9/187
Filed: 1980-01-16
Abstract: The locking system for the telescopic sections of a fire escape or support for an overhead working platform is operated by a swinging arm attached to the lowermost section. This is connected to a control cable (3) which is attached at the other end to a swinging plate (5) on each section, controlling two locking arms (7) on opposite sides of the section. Each locking arm has a set of locking fingers (6) projecting from it, to engage an adjacent section. When the swinging plate is tilted by the cable, a cord with a spring (29) incorporated is pulled so as to rotate the locking arm into the locking position against the force of a spring (30) around the top. This arm is connected by a further cord (32) to the second arm on the other side, so that this is locked at the same time.

IPC: A23B4/02
Filed: 1980-05-23
Abstract: Binding meat particles is carried out in two stages; in the first stage the particles are kept in motion, pref. for a comparatively long period, with careful monitoring of their temp. according to the particle size, nature and quantity of the liq. added. In the second stage the temp. is raised above the protein decompsn. temp., the particles still being kept in motion. This second stage is pref. carried out with a rapid but short temp. rise. A movable container is used for receiving and treating the particles and is equipped with a temp. measuring appts. This appts. may be coupled to a device for controlling the movement data. In addn. cooling and vacuum treatment may be carried out. The movement and temp. treatment of the meat particles is standardised and is rendered independent of accidental or subjective control measures.

Title: Cellular bricks mfr. - adding crushed coke from low-temp. refuse carbonisation to clay before firing
Inventor: HAESSLER ANDREAS ING GRAD
IPC: C04B38/06
Filed: 1980-07-22
Abstract: Cellular bricks and tiles are produced by adding crushed coke from the low-temp. carbonisation or pyrolysis of refuse material to the clay. The usual firing temps. in kilns are 1000-1200 deg.C so that any contaminants in the material are made innocuous. This produces high-quality cellular bricks and tiles and at the same time it locks up the heavy metal constituents which remain in the coke and otherwise present a problem for the disposal.

Title: Free-standing support for different-sized skis - has twin pairs of rails with base and displaceable transverse member
Inventor: LECHNER DIETER
IPC: A63C11/02
Filed: 1980-07-30
Abstract: The stand is comprised of a pair (20) of upper horizontal longitudinal rails and a pair of lower horizontal longitudinal rails (22) which are fastened in two end frames (12,13). A gap of constant width is maintained between the pairs of rails, with the gaps at top and bottom being vertically aligned.

Title: Control valve with expansion elements - is used to provide safe control of operating temperature to prevent overheating
Inventor: SANDAU HARTMUT ING GRAD
IPC: F15B21/04
Filed: 1980-07-31
Abstract: The control valve is for use with viscous liquids, and is designed to provide protection against the possibility of overheating. The unit has two sealed expansion capsules that react to increases in temperature. The oil or grease is supplied to an inlet (14) and passes to outlet (16) over a controlled restriction. A pilot restrictor (25) is located in a control spool (23) that moves under the application of high pressure to establish a main flow path (29,30,34).

Title: Tipping mechanism for lorry cab - has tipping hinges carried by downward sloping chassis extension in front of front axle
Inventor: ELLER BRUNO
IPC: B62D33/07
Filed: 1980-08-14
Abstract: The tippable lorry cabin is fitted on the vehicle chassis (12) over the engine and gearbox in front of the front axle (11). The cabin floor is cut away to allow the cabin to be hung closer to ground level. The cabin is fixed to a downward sloping extension frame (16) through hinge pins (20).

Title: Towed two-wheel beet harvesting machine
Inventor: STAHLBOCK KLAUS
IPC: A01D27/00
Filed: 1981-01-15
Abstract: In a towed two-wheeled beet harvesting machine, in front of one wheel of which the lifting assembly is arranged, the intention is to remove the ridges which have arisen between the rows of lifted beet without special smoothing devices. This is achieved by virtue of the fact that the spacing of the running wheels is an uneven integral multiple of half the spacing between the rows, that the width of the tyres of the running wheels corresponds to the spacing between the rows, that the tyres of the running wheels are pneumatic rubber tyres with an inflation pressure of 0.5 to 1.5 atmospheres above atmospheric pressure and in that a slope (stabiliser) plate is arranged behind and to the side of the wheel in front of which the lifting apparatus is not arranged. Uniform loading of the soil during lifting is thereby simultaneously achieved. The beet harvesting machine furthermore has increased stability as regards its position when working on a slope.

Title: Thread protection device for tube ends
Inventor: DREYFUSS WILFRIED
IPC: B65D59/06
Filed: 1981-04-09
Abstract: The invention relates to a thread protection device for screwing onto or into the ends of tubes provided with a thread. In order to facilitate inspection of the inside of the tube, the thread protection device is provided with a moisture indicating device which can be read off on the outside and is arranged in the bottom of the thread protection device. The moisture indicating device is preferably a moisture indicator with a colour display for different moisture ranges and is arranged in a threaded stopper with a window, said stopper being screwed into the bottom of the thread protection device. By means of this design according to the invention, it is no longer necessary to remove the thread protection devices for the purpose of inspecting the inside of the tube since, with the aid of the moisture indicating device, it can be recognised whether or not there is a degree of moisture inside the tube which will permit rusting. <IMAGE>

Title: Projection device for planetaria
Inventor: KUEHN GEBHARD DIPL PHYS
IPC: G09B27/02
Filed: 1981-06-26
Abstract: The invention relates to a projection device for planetaria for generating cycles of phases in representations of the moon and planets. The aim of the invention is a realistic reproduction of this cycle of phases. The object of simplifying the diaphragm drive mechanism required is achieved by enabling at least one diaphragm, which in accordance with the invention is attached to at least one tensioned, endless guide belt, to be inserted into the projection beam path. It is advantageous to mount a plurality of diaphragms having mutually differing shapes and sizes on the guide belt. It is favourable for the stability of the system if the diaphragms are mounted between two synchronously running guide belts. The invention differs from the known technical solutions in that the diaphragms are guided continuously and without vibration through the projection beam path.
