Patent DE-4321207-A1 (DE)
Title: Circuit arrangement for pulse propagation time measurement (delay time measurement)
Inventor: JUENEMANN OTTO
IPC: G01S7/487
Filed: 1993-06-25
Abstract: The invention relates to a circuit arrangement for pulse propagation time measurement, consisting of a radiation detector, a preamplifier, a comparator, a delay element and a digital output stage which receives optical direct signals and reflex signals of unknown amplitude, converts them into electrical signals, amplifies them and forms digital output signals by means of comparison, and passes them onto the digital output stage which uses the trigger edges of the digital output signals to determine the propagation time of the reflex signals. Time separation between, on the one hand, the reception and the preamplification and, on the other hand, the supply of the digital output signals to the output stage by a delay element avoids any switching interference being fed back onto the areas of the electrical signal which are relevant for the comparison, which enables precise determination of the timing of the trigger edges. <IMAGE>

Title: Cutting method for stripping optical fibre coating - using two relatively adjusted blades with spaced cutting edges on either side of clamped optical fibre axis
Inventor: KAIZU RYOSUKE
IPC: G02B6/245
Filed: 1993-08-20
Abstract: The stripping method is used for removing the optical fibre outer coating comprising two successive layers. The optical fibre is clamped at two or more spaced points and blade holder (15) with a pair of cutting blades (16a,16b) with straight cutting edges (17a,17b) facing one another in the same plane at right angles to the optical fibre axis is brought into contact with the clamped optical fibre. The cutting blades can be spaced to remove the outermost layer of the outer coating, while leaving the innermost layer intact by adjusting them transverse to the  optical fibre axis. ADVANTAGE - Provides high stripping accuracy and reproducible stripping characteristics.

Title: Data processing system and method of organising data in data processing systems
Inventor: MUELLER FRANK DIPL ING
IPC: G06F17/30
Filed: 1993-09-21
Abstract: In a novel organisation of data in data processing systems, data of the same type are sorted in each case into a basic information unit (1', 2', 5') and at least one logic combination file (6) is created, in which data from different basic information units (1', 2') is stored and provided with different, freely selected selectors which characterise a logic combination, the logic combination file (6) being designed in such a way that a search can be made for the selectors. An organisation of this type avoids the emergence of long access times due to multiply nested search operations. <IMAGE>

Title: Device for mounting an agricultural appliance on a tractor
Inventor: EIDAM MANFRED DIPL ING
IPC: A01B71/06
Filed: 1993-09-29
Abstract: The invention relates to a device for mounting an agricultural appliance 2 on a tractor 1, a drive connection additionally being received between the power take-off shaft of the tractor and the drive of the appliance. This purpose is served by a gear unit 8 with two bevel-wheel angle gears 9, 10 arranged one above the other, of which one is fixedly connected to the drawbar of the appliance and the other can be connected to the lower links of the tractor via a mounting (12). The trailer mounting allows a pivotability of the tractor and appliance relative to one another about a vertical axis 25, a transverse axis 26 and a longitudinal axis 27, whilst, in order to achieve the pivotability, the mounting 12 is mounted relative to the gear unit 8 about the longitudinal axis 27 by means of a sleeve 47 on a flanged housing 39 which is arranged coaxially to the first connecting pin 20 of the gear unit 8. An improvement in the transmission of tensile forces is achieved thereby. <IMAGE>

Title: Device for wiping the tines of a grab on a material crane for agricultural purposes
Inventor: RECK ERNST
IPC: B66C3/04
Filed: 1993-10-19
Abstract: In the use of grabs, the problem of material to be transported, mainly silage, sticking to the grab tines when the grab is opened frequently occurs. Removal is often only possible with difficulty. The working sequence is consequently disturbed and the efficiency of the crane apparatus is reduced. To solve the problem, two frames with wipers are pivotably fastened to the jaws (5) of the grab by means of bolts (2) and brackets (3). The wipers (6) are arranged in such a way that the grab tines (7) can move through between each two wipers (6). The frames (1) are pressed against the stop (4) when the grab filled with material to be transported is opened, and the grab tines have to move through between the wipers, as a result of which they are freed of material to be transported. The device is suitable for crane apparatus having grabs of the most varied manufacture. Grabs can also be subsequently equipped with the device. <IMAGE>

Title: Hologram scanner with compensating plate and concave and plane mirrors - diffracts laser beam towards or in opposite direction from midpoint of curved scan line to produce linear trace on projection surface
Inventor: KIM YOUNG SIK
IPC: G02B5/32
Filed: 1993-11-06
Abstract: A laser diode (10) emits a beam towards a hologram scanning disc (30) which is rotated by a motor (20). The beam exhibits a curved scan line corresp. to the hologram pattern, and the position error of the image projected on to a surface (70) is a measure of the laser temp. difference by wavelength variation. The plane mirror (40) reflects the diffracted beam on to the concave mirror (50) which redirects it through the compensation plate (60), forming a straight line on the projection surface during each scan. USE/ADVANTAGE - For image production. Follows current trends towards compact, lightweight and miniaturised scanning devices for holographic imaging.

The components are placed on the pivotal devices by inlet mechanisms and ejected from the rotary devices by ejectors (9) whilst the component is still in one of the stable positions. The component can be moved between the inlet and ejector devices along channels (25) having a base (21) and two side walls (23). The width of the channel increases from one end associated with the inlet to the other end associated with the ejector. ADVANTAGE- Simplified construction reducing dwell time of components in machine.
Patent DE-4402064-A1 (DE)
Inventor: OPPITZ HORST
IPC: A23B7/144
Filed: 1994-01-25
Abstract: The invention relates to a process for combatting pests (rodents, insects) in loose material, especially grains, e.g. cereals. One long-used and effective method of treatment involves gassing with phosphane (PH3) or other pesticides available in gas or vapour form and heavier than air. According to the invention, CO2, preferably in the form of flakes of dry ice, is also caused to penetrate by gravity into the loose material. Although the quantity of pesticide may be greatly reduced, the pesticidal effect acts much more quickly. It is particularly advantageous to use zinc phosphide as the precursor for the pesticide and dry ice as the source or CO2.
