Title: Gearing for converting non-uniform into uniform motion - has pair of eccentric gears with periodic non-uniformity
Inventor: KNOOP GERHARD
IPC: F16H35/02
Filed: 1973-11-10
Abstract: The gearing has an input shaft driven at a 2:1 ratio from a gear which is driven with periodic non-uniform motion by a crank connecting rod. The input shaft has a first eccentric gear meshing with a second eccentric gear secured to an output shaft. The eccentricity of the latter gears is such that the periodic change in speed of the input shaft is compensated for by the periodic non-uniformity of the speed of the driven relative to the driving eccentric gear. The invention may also be used with advantage in cases where the resistance to a drive varies periodically.

Title: Vibrating ballast processing appts. - ballast packed under railway lines by sequential vibrations of various amplitudes
Inventor: SIEKE HELMUT DIPL ING
IPC: E02D3/068
Filed: 1974-01-07
Abstract: A first vibration is applied to ballast having a large amplitude but of short duration and is followed by a second vibration of smaller amplitude but of greater duration. The vibrations are applied hydraulically to a work tool. Over a working cycle the pressure in the working cylinder gradually rises. Various vibration producing devices are applicable but are based around an oscillating spool value which switches pressurised oil supplied from a source through ports in the spool valve cylinder wall. In processing friable stone a low powered, long duration impulse can be used in the working direction while the working tool, set in the material, is released by a high powered, short duration impulse. The arrangement is reversed for hard stone processing.

Title: Buffer register operation in data processing system - with optimum ratio of effective to minimum access time uses hierarchical memory
Inventor: PFEIFFER KLAUS DIPL PHYS DR
IPC: G06F12/0802
Filed: 1974-06-05
Abstract: The data processing system has a hierarchical working memory acting as a rapid access memory to memory words selected by a search process through an address portion organised as an associative memory. After each search a condition signal is derived from the signal condition of the individual stages (FF1-FFn) of an address coincidence register (TR). In the case of an unsuccessful search a write signal is generated in a word wire of the address portion allocated to buffer register line having the first stored word. The condition signal initiates a read cycle in a main memory in which the sought stored word is written into the selected line of the memory's data section, whereby the condition signal returns to its original state calling for a search of the address portion.

Title: Laser appts for measuring distance and velocity relative to plane - with beam deflection speed stabilized using additional detectors
Inventor: BODLAJ VIKTOR DR ING
IPC: G01S17/50
Filed: 1975-02-28
Abstract: A laser beam periodically scans the region of the object and is diffusely reflected by the object. The reflected radiation is received by a detector near the transmitter which can receive light only from a certain direction. Distances are determined from the interval between deflection of the beam and the appearance of a detector signal, as in 22 29 887. In order to stabilise deflection speed of the beam deflector (9), the laser beam reflected from a semitransparent plate (24) is registered by two additional detectors (25, 25'). When the time interval between their signal differs from a specified value, the control voltage applied to the deflector is readjusted.

Patent DE-2527994-A1 (DE)
Title: Fibrous web thickness control during stretching through needles - by transmitting signal after time lag, to alter draft
Inventor: MUELLER PETER DIPL ING DR ING
IPC: D01H5/38
Filed: 1975-06-24
Abstract: During its treatment in a stretching unit, the thickness of a web of fibrous material is regulated by measuring the thickness of the web before stretching, and using this figure as a datum, for the altering after a time lag, of the amount of draft, so as to make the thickness of the product uniform. The control signal which influences the amount of draft is delayed for a length of time determined during operation, before being transmitted, and the distance between the point at which the measurement is taken and the point at which the drafting begins is increased or reduced proportionally to the speed of the web in the drafting zone. The device uses a delay in time instead of a delay dependent upon the run of fibre, so that it is considerably cheaper.

Title: Improving flow characteristics of sticky or granular materials - using loudspeakers to direct sound waves at specified frequencies at material in silo
Inventor: MATHIEU ERNST-ULRICH
IPC: B65D88/66
Filed: 1975-08-06
Abstract: In cleaning off, loosening and improving the flow characteristics of granular, small piece or thick flowing materials in chambers, vessels, silos, etc. sound waves are used which transmit oscillations to the particles of the materials. This leads to a reduction of internal friction and to a release in tension. The sound is generated by electro-magnetic or electro-mechanical loudspeakers and is beamed from them. The frequency of the sound may be varied in accordance with the operating requirements, with the sound volume being similarly variable. The current requirements of the installation can normally be supplied by the domestic supply of 220 Volts, 50 Hz. The installation may be used as a stationary or a mobile operating unit.
Patent DE-2536538-A1 (DE)
Title: Fibreboard pressed at controlled pressure and temperature - to give varying density profile and controlled residual moisture
IPC: B27N3/20
Filed: 1975-08-16
Abstract: The Parent Patent describes a method of pressing chipboard, fibreboard or the like in a plate press, consisting of applying a press. for a predetermined period and then subjecting the matl. to pressing temp. The electric power supplied to each heating plate below and above each board is varied during pressing in order to regulate the temp. as a function of time. In this Patent of Addition the pressure is maintained constant for a period and, during the same period, the heating power is raised constant only until the desired temp. has been reached and is then reduced so that the pressing temp. is only maintained or, opt. after a short pause, is slightly increased. The heating power is an energy impulse having steep flanks so that the rate of temp. rises with time is greater than 0.5 degrees per second. This process enables finished chipboard, fibreboard etc. to be given a defined density profile across their thickness and, opt. also, a defined residual moisture. The quality of the prod. is improved.
