Title: Controlling an impulse cutter in continuous casting machine - by measurement of casting speed
Inventor: SAWELIEW ANATOLIJ S
IPC: B22D11/16
Filed: 1974-01-21
Abstract: An impulse cutting machine for cutting billets of preset length from a continuously cast strand of metal is controlled measuring the time which the forward face of the strand takes to pass between two points spaced along the axis of casting travel, the two points corresponding to the length of travel of a cast strand moving at its maximum speed in the maximum time it takes to fill the combustion chamber of the impulse cutter with fuel; the point furthest from the cutter lies the same distance from the first point as does a third point which corresponds in distance from the impulse cutter equal to the desired length of billet; and (b) comparing the speed of the strand with the speed of filling the combustion chamber with fuel; the delay in filling the chamber being selected so that the chamber is filled when the forward strand face reaches the third point. Although the cast strand speed may vary, constant lengths may be cut.

Title: Remote stopping and starting system for diesel engine - with fuel feed and starter motor actuated via delay cct. by radio receiver
Inventor: BUCHER JEFFRY CLIFFORD
IPC: F02N11/08
Filed: 1974-03-12
Abstract: A receiver for a command signal produces an appropriate signal to control the engine. A start signal causes the battery to be connected to the starter motor and to energise the engine fuel supply system, with a voltage from the generator causing the starter to be disconnected from the battery upon the engine starting whereas an engine stop signal causes the fuel supply to be interrupted thereby stopping the engine. The signals are transmitted in coded form while a protective mechanism cuts off the fuel supply in any one of a number of events such as the engine running at too high a speed, not starting when rotated by the starter motor or when the engine has been running on no load, or idling, for a predetermined time.

Title: Fibre suspension impurity removal - through clearing channels mounted in stationary perforated drum under valve control
Inventor: FREDRIKSSON BOERJE INGEMAR
IPC: D21D5/06
Filed: 1974-03-27
Abstract: Designed for the removal of impurities from the fibre suspension to be used in paper mfr., the suspension is swirled through a perforated drum enabling the impurities to be spun out against the surface to build up in a layer, and to be passed through regularly-spaced apertures into clearing channels operating under valve control. This reduces the lengths of the impurity layer, by the aperture interval, to improve the removal of collected impurities and prevent the surface of the drum from becoming clogged.

Title: Starting torque control for D.C. motor with large loads - adds extra continuous function to required current value for starting
Inventor: WEHRMANN CLAUS DIPL ING
IPC: H02P1/18
Filed: 1974-04-11
Abstract: The starting torque control, is used in conjunction with d.c. motors with large loads, and adds in a continuous function to the required value quantity of the current so that the armature current after starting falls to the level represented by the required value quantity for continuous operation under normal running conditions. The initial value of the armature current may be either independent of or dependent on the representative quantity; similarly the additional function may be either dependent on or independent of the representative quantity, but its duration is dependent on the speed of the d.c. motor. The armature current in falling from its initial to its steady state value may follow a given curve when plotted against time.

Title: Control system for trains on railway track - has sensors in track sections and central command station
Inventor: BROCKMANN JUERGEN DIPL ING
IPC: B61L27/04
Filed: 1974-06-21
Abstract: The position of each train within a given track section is monitored and the data is supplied to a central station in addition to the data concerning the actual travelling speed and the given braking capacity. Each track section length is approx. 30 metres. The central station evaluates allowable maximum speeds for each train on the basis of obstacles, slow speed sections and the stops at stations. This information is combined with the actual travelling speed and a command is formed which is transmitted to each train. The evaluation system requires only small storage capacity for information and the search area of an existing line configuration is adapted by weighting of the lengths of individual line sections.

Patent DE-2442648-A1 (DE)
Title: Differential for hydraulic transmission - with pressure valve held in mid position by opposing pressures from servo motors
Inventor: JAECK PAUL
IPC: B60K17/10
Filed: 1974-09-06
Abstract: The hydraulic transmission has separate pumps and hydraulic circuits for each driven wheel, on a common axle. The hydraulic pressures are taken to a special compensating valve which has a floating element held in its mid position by the opposing hydraulic pressures and by springs. If the pressure drops by more than a set amount in one circuit, i.e. the wheel on that side rotates faster than the wheel on the other side, then the valve element is displaced to enable fluid to flow to the other side. This provides a simple hydraulic differential and ensures optimum traction. The system is simple to instal, even in existing transmissions.

Title: Amplification control in phase locked loop - with protection against reference input disturbance using adjustable resistor and coincidence circuit
Inventor: BRAUCH ULRICH
IPC: H03L7/10
Filed: 1975-02-04
Abstract: A phase locked loop control provides a facility for varying the regulating circuit amplification independently of the output and a separate facility provides protection against input disturbances. An operational amplifier (1) with a control input over a resistor (9) has a reference frequency input (6). The output operates over a low pass filter (2) to generate a correcting signal for the phase regulated oscillator (3). Feedback to the comparator (1) is over a divider (4) and an adjustable resistor (11) permits the amplification to be varied. A transistor (12) is controlled by a coincidence circuit operating on the reference input (6) and the feedback value. Any disturbance in the reference produces switching of the transistor to limit the regulating circuit amplification.
