Patent DE-2518267-A1 (DE)
Title: Speed control for several drives - forms actual and required speed difference for each drive and relative positions of drives
Inventor: O'CALLAGHAN GERALD FRANCIS
IPC: H02P5/56
Filed: 1975-04-24
Abstract: The speed control for several drives with equal or proportional speeds, has tachogenerators or similar producing a pulse train proportional to the actual speed of the loads. Summing circuits add each actual-speed pulse train to a reference pulse train and produce positional error signals characterising the difference between the two sets of input pulses. The positioned error signals are used to control speed control circuits. Position detectors monitor the actual position of the loads relative to a fixed reference position, and pass their outputs to a synchronisation unit that forms a signal representing the relationship between the actual positions of the loads.

Title: Mounting for steel or plastic containers - with inter foamed plastic layer between container bottom and supporting saddle
IPC: B65D90/12
Filed: 1975-04-30
Abstract: Mounting for steel or plastic containers with a curved bottom has a saddle with supporting faces fitting the curve of the container bottom, and an intermediate layer of foamed, esp. polyrethane matl. between the container bottom and the supporting faces of the saddle. Enables the container to be rapidly and cheaply mounted on the saddle by foaming the polyurethane matl. between the container bottom and the receiving face of the saddle. The foam matl. fills irregularities in the surfaces of the container bottom and receiving face, and guarantees an exact filling between the surfaces. Good support is provided for the container.

Title: Exchange call signalling circuit for PBX exchange - has optoelectronic coupler which is arranged between exchange line and PBX equipment
Inventor: REINICKE JOCHEN ING GRAD
IPC: H04M7/00
Filed: 1975-05-10
Abstract: The exchange call signalling circuit, for PBX telephone exchanges, has extremely high sensitivity to exchange line ac call current whilst maintaining dc isolation between exchange line and PBX equipment. The isolation is achieved using an optoelectric coupler (15, 19). The coupler triggers the release of a call signal in the PBX equipment on receipt of a call current on the exchange line. The optoelectric coupler consists of an LED and phototransistor. The LED is shunted by an oppositely poled diode and connected to both exchange line wires. The photo- transistor acts as switch for the PBX call voltage source.

Title: Draw trolley for drawing small rods and profiles - out of an extrusion press, with automatic release of gripper tongs
Inventor: PUEHRINGER WILHELM
IPC: B21C35/02
Filed: 1975-05-17
Abstract: Drawing device used on a metal extrusion press for guiding and drawing the extruded rod or profile out of the extrusion die, using gripper tongs mounted on a trolley drawn by a cable drive. The novelty is that the tongs are mounted on a tube which can be axially displaced between rollers located on the trolley when the cable is wound on a drum (I) by a variable speed motor; a spring coupling joins the tube to the trolley; a second variable speed motor uses couplings to drive drum (I) or a second drum (II) with a second cable drawing the trolley; and a third motor and coupling are employed to drive the trolley back to its starting position adjacent to the extrusion die. Used e.g. for hot extruding rod with a small cross section where the drawing tongs prevent the distortion or bending of the rod; the tongs operate automatically.

Title: Quality control on synthetic material processing machines - which is effected by continuous comparison and adjustment of processing conditions
Inventor: KALWAR KLAUS
IPC: G01G19/00
Filed: 1975-07-17
Abstract: The throughput of raw material on synthetic processing machines is measured continuously or intermittently as a weight per unit of time, and compared with a predetermined nominal figure for the ejection of the product, in a digital circuit. The result is used for regulating the production process as it proceeds. All the analog measurement data together with the values predetermind as nominal for the process are convered to digital impulses and the information obtained is used for controlling the process and for accounting purposes. Method allows detection of errors before they cause lowered quality of the product and serious losses of material and energy occur.

Title: Drying installation for sugar beet - uses hot gases from soot blower for firing in after combustion chamber
Inventor: PAULI BALDUIN DR
IPC: F23C6/00
Filed: 1975-10-25

Two friction rollers (60, 62) are mounted at opposite sides of the projector to drive the supporting band in either direction. The band travels between guide rails (66, 68) in the region between the condenser lens (64) and the projecting lens (54). The guide rails are tensioned together by a spring (70). A photocell (72) detects markings, e.g. perforations (10) for positioning. The band can be stored in a casette.

Title: Continuous railway track distortion travelling metering process - uses calculator with storage units monitoring rail top comparative setting functions
Inventor: BREYER WALTER
IPC: G01B21/22
Filed: 1975-11-11
Abstract: The rail-monitored travelling track-measuring vehicle is used in the continuous measurement of railway track distortions. As the vehicle moves, change in the function of the height of the two rail top edges is continuously computed, with the aid of a calculator, with storage devices. This is programmed so as to store a metered reading and the time of reading, in the event of agreement of this reading with one of the input limit readings. Similarly, the next agreeing reading, and its time, are stored, and the quotient of the differential is resolved, this programmed process being continuously repeated. The system is not dependent on the base length.

Title: Ski with spring mounted sole plate - has spherical recess in sole plate end to match boss screwed to ski
Inventor: MEYER HANS
IPC: A63C9/00
Filed: 1976-01-20
Abstract: The ski (1) is provided with a sole plate (2) which extends for about one third of the length of the ski. The end of the sole plate (2) is provided with a spherical recess (3) which matches the boss which is screwed to the ski. The sole plate is clamped to the boss by a knurled nut (10). The other end of the sole plate is supported by a tension spring housed in a tubular member. Supporting the sole plate by a spring gives the skier a better control of the ski when turning and also requires less effort and so reduces fatigue. Alternative designs use a leaf spring instead of the tension spring.

Title: Warping blade control system - has positive and automatic guide unit controlled by diameter of wound material and pitch of cone guide bar
Inventor: BRUEES WILHELM
IPC: D02H3/00
