Title: Drive linkage for IC engine - has piston connected to crosshead opposite crankshaft to modify piston velocity to improve efficiency
Inventor: SCHUELER GERHARD DR ING
IPC: F01B9/02
Filed: 1979-05-19
Abstract: The piston (1) has a pair of piston rods (2) running on either side of the crankshaft to a crosshead (3) which moves with the piston in guides on the opposite side of the crankshaft. There is a connecting rod (4) from the crosshead to a crank (5) on the crankshaft. A fly-wheel is attached to the crankshaft. For uniform rotation of the fly-wheel this linkage gives a lower speed of the piston immediately after top dead centre than a direct connection from piston to crankshaft. The speed at which the piston is pulled away from the expanding gases is reduced and they can do more work.

Title: Cylindrical workpiece surface rolling machine - has cone distortion detector supplying comparator to control sliding movement
Inventor: ROTTLEUTHNER HEINZ
IPC: B24B39/02
Filed: 1979-09-04
Abstract: The machine rolls a cylindrical workpiece surface smooth, using a tool comprising a hollow cone and a cage coaxial to and sliding axially in relation to it. Taper rollers slide radially in the cage slots and roll against the cone face towards the cylindrical face of the work. A drive causes cone and work to turn and slide in relation to each other, while a setting device slides the cage in relation to the cone. The cone (6) also rolls an internal cylindrical work surface smooth (4), and its wall thickness is such as to allow distortion beyond the side furthest from this surface (25). A distortion detector (24) acts against the cone face (25), its output being fed to one input of a comparator, whose other input is supplied with an adjustable desired value. The relative sliding movement of cone and cage (9) by the setting device depends on the comparator output signal, until the value from the feeler equals the desired value.

Title: Engine driven alternator individual wheel motorised propulsion system - has stepping motor control system with variable frequency generator including gate controlled rectifiers
Inventor: FENGLER WERNER HERMANN
IPC: B60L50/15
Filed: 1980-02-02
Abstract: The constant-speed continuously-running low-powered diesel engine or turbine drives a two-phase alternator, the output from which for direct drive, flows to the stator pole piece windings of four independently-rotating stepping motors operating synchronously with the alternator. Each stepping motor is connected to a traction wheel of a motor vehicle, propelled at a limited maximum speed sufficiently to overcome normal wind resistance over a level road. In starting, during acceleration, and for propulsion at higher speeds, direct current from a storage battery is caused to pulsate and is added to the current from the alternator to the stepping motors. A circuit controls selectively the frequency of a variable frequency generator electrically connected to the pulse-responsive electrical power system to vary the frequency of the current supplied to the stepping motors and thus vary the vehicle speed. During idling, the alternating current from the alternator is rectified and recharges the battery.

Title: Coking coal prepn. flow sheet - using five stages for prodn. of set moisture and ash content
Inventor: KELLERWESSEL HANS
IPC: B07B9/00
Filed: 1980-02-23
Abstract: Method for the prepn. of coal, esp. of raw smalls to produce coking coal of a fixed max. permissible moisture and ash content, consists of five stages. After screening to an effective separating size of 0.5-2 mm, a wet cleaning by dense medium, jigs and dewatering is followed by drying to a free-running consistency. Dry-cleaning of the underflow from stage 1 by dry cleaning tables produces the concentrate which is added in the last stage to the smalls from stage 2. This procedure fully compensates for the increasing deterioration of the run-of-mine coal by rising moisture content (for dust suppression reasons), and rising fines and ash content (for mechanisation reasons).

Title: Device for detecting the transmission load, engine load and fuel consumption economy of the operation of a motor vehicle
Inventor: WEBER ALFRED DIPL ING
IPC: B60K26/00
Filed: 1981-04-14
Abstract: The object of the invention is to save fuel in the operation of a motor vehicle and to safeguard the engine and transmission. The invention is characterised in that the instantaneous engine operating state is compared with the position of the accelerator (= fuel actuating device) or the linkage leading from this to the throttle valve and/or transmission device and/or the position of the throttle valve itself. This sensing of the said position is possible both magnetically and electrically, mechanically, electronically or optically in digital or analog form. It is now possible by means of the invention to immediately detect the very first stages leading to a possibly unfavourable operating state and, where necessary comparing this with the actual instantaneous operating state (engine speed, speed of travel), to indicate larger differences (for example, too much fuel supply = "racing start" or too little fuel supply = engine braking) visually or audibly to the driver and thereby to modify his driving behaviour or to restore more economical driving behaviour by switching on an open or closed loop control circuit.
