Title: Concave guide for a combine harvester
Inventor: KAMBEITZ BERNARD G
IPC: A01F12/24
Filed: 1990-11-22
Granted: 1995-01-03
Abstract: A threshing concave or concave guide for a combine harvester  is described.   The concave  is positioned in its conventional  location on a combine,  however the design has been modified.   The crop  is directed into the concave by threshing cylinder rasp bars.  As the crop enters the guide, at  its base,  there are positioned a number of angled bars that direct the  incoming  crop away from the centre of the concave.    Traditional  concaves  move  the  grain toward the centre  of  the  device.    The  angled  bars  of  the  present invention distribute the load more evenly along the concave surface,  thereby resulting in a decreased wear and tear of the  concave  and  rasp  bars.   The design also reduces  the damage  to  separated  grain  as  the  grain  slides  into  the leading edge of the device rather than abruptly hitting the sharp edge of a first cross bar, as in traditional concaves.

Inventor: BEST JOHN S
IPC: G11B21/10
Filed: 1990-11-26
Granted: 1995-05-16
Abstract: A method and means is described for writing data on a recording medium,  such as a disk or tape, containing servo samples in such manner that the number of servo samples is increased with a minimal increase in overhead (non-data) regions.  The tracks on the medium are divided into a plurality of maxi sections, each of which contains all fields with servo and associated overhead information and also a data field.  At least one micro servo section containing only a portion of said information is located within each data field.     As each micro servo section passes by an associated recording  head,   writing  and  reading  of  data  is temporarily interrupted, but resumed when the micro servo section moves beyond the head,  in such manner  as to require minimal  resynchronization of  said data during reading.     Using a phase continuous clock, data is written in both portions of a data field to either side of each micro servo section in one pass of the disk or tape relative to the head.  The micro servo sections contain no timing reference address mark and require no data encoder/decoder flush or synchronization byte to resume reading in the portion of the data field following each micro servo section.

Title: Control device for a passenger retaining and/or protective system for vehicles
Inventor: EIGLER JUERGEN
IPC: B60R21/00
Filed: 1990-02-19
Granted: 1997-01-07
Abstract: A control device for a passenger retaining and/or protective system for vehicleswith a sensor which generates an analog output signal corresponding to the acceleration or deceleration acting on its point of installation in the vehicle, an evaluation circuit assessing the sensor output signal and a triggering circuit which triggers the system when the threshold is exceeded. The time cycle of the sensoroutput signal is subjected to several different evaluations (1, 2, 3, 4, 5) in that said sensor output signal is taken to an evaluation circuit operating in a complex manner or to several such circuits operating differently, which assess the cycle according to differing criteria and thus with several differently defined thresholds. At least one of these evaluation circuits (2) is so constructed and operated that it can differentiate: between at least two different kinds of accident (frontal and oblique) with differently defined thresholds depending on the seriousness of the accident. At least one of the evaluation circuits (3, 4) is constructed and operated in such a way that it establishes the seriousness of the type of accident allocated to it from the events and the threshold allocated to it. The outputs of the evaluation circuits are connected to the inputs of an interlink component (23, 24, 234, 1234) which transmits the result to the triggering circuit. The interlink function is selected so that the system is triggered only if the evaluations indicate both a defined type of accident and the exceeding of the threshold(s) specifically allocated to the type of accident concerned.
