Patent DE-2427321-A1 (DE)
Title: Device to determine acceleration time of a motor - is for equipment running at different speeds and under different loads
Inventor: SCHLAPKOHL JOACHIM ING GRAD
IPC: G01M15/04
Filed: 1974-06-06
Abstract: The acceleration time is the time required by the motor to reach its nominal speed from absolute rest. Pulses generated by the pulse generator mounted on a motor shaft are applied to a counter operating in the sampling mode. They generate in a time interval limited by two pulses, which a clock generator removes after a time interval has elapsed, the changes in the counting store. Preset program data are stored in the counter. The evaluation logic monitors dynamic changes of data in the counting store, and generates a signal at its certain state which stops the time count and/or activates a further motor control. Depending on the selector switch position, the switching means delay is adapted to motor running.

Title: Internal combustion engine piston - has layer of saw tooth-shaped galvanically deposited hard iron on shell
Inventor: WACKER ERICH DIPL ING
IPC: F02F3/10
Filed: 1974-08-10
Abstract: On pistons of internal combustion engines it is important to supply a sufficient quantity of lubricant, particularly to the hottest part of the cylinder, i.e. to the head. To achieve this radial grooves of various shapes have been used, acting as lubricant storages and spreaders. However the apex part of the grooves tended to wear out quickly or cause excessive wear on the cylinder. The present concept uses a layer of galvanically deposited hard iron in combination of a saw tooth-shaped profile of the grooving to achieve an improved lubrication. Profile angles used on the grooving are in the range of 100 to 170 deg., with included angles of 0.5 to 10P and with a depth of 1 to 20 um.

Title: Electronic integrator using voltage frequency converter - driving into counter sets bistable opening feedback relay to allow integrating amplifier output to rise to ref. value
Inventor: GIELOW GUENTHER DIPL ING
IPC: G06G7/161
Filed: 1974-10-09
Abstract: An electronic integrator circuit operates to generate an output frequency, and this frequency is proportional to the input voltage which is then used to actuate a counter producing a time integration of the input voltage. The voltage frequency conversion operates according to a given mathematical formula, and the frequency input (fo) sets a flip-flop (24) and the feedback relay is open (18). The operation amplifier (12) output voltage increases until it equals the reference (VREF) and is indicated by a comparator (20). The flip-flop resets and the relay closes. The flip-flop output (I) duration is thus proportional to input voltage (Ue2).

Title: Impulse type heavy - oil burner for tunnel kilns - fine atomizing is achieved by pre-heating oil within kiln
Inventor: RINKE CARL
IPC: F23D11/26
Filed: 1975-01-20
Abstract: Atomized oil is squirted at approximately one-second intervals into the comparatively low kiln through a fine jet (22) at the extreme end of a supply pipe (14) which projects down into the kiln from roof level. An ejection plate (18), which fits closely above the jet plate (21) is turned to and fro (spindle 10) through perhaps 90 deg., and transmits fuel (15) every time a narrow channel (20) in its lower face moves across the jet opening (22). Variations in fuel viscosity (the burner is designed for both heavy and medium oils) are catered for by using the pressure of the incoming fuel itself to work the motor that drives the jet mechanism. The fuel is heated to 150 deg.C in the jet-supply pipe (14), where this projects into the hot kiln (the water in the fuel vaporizes).
