Title: Process for the production of directed short-fibre fleeces
Inventor: VORBACH DIETER
IPC: D04H1/74
Filed: 1993-06-08
Abstract: Process for the production of oriented short-fibre fleeces, parallelisation taking place on a mechanical principle. The practicability of the process is independent of the properties of the fibres. Both polymer fibres, carbon fibres and metal fibres as well as mixtures of these can be oriented. The principle of the process is that the fibres are applied to a plate having webs or grooves. The spacing of the webs or grooves is conventionally smaller than the short-fibre length. This plate is set in mechanical vibration via a vibration generator, so that the fibres are at the same time oriented. The oriented fibres can be received in a continuous process by a transport device, whilst, in a subsequent operation, a consolidation of the fleece and the introduction of the matrix can be carried out.

Patent DE-4336799-A1 (DE)
Title: Device for the detection of, and reading out from, transponders which move relative to this device
Inventor: HOEFGEN GUENTER DR ING
IPC: G01S13/78
Filed: 1993-10-28
Abstract: A device is specified for the detection of, and reading out from, transponders (T) which move relative to this device and carry information, the distance of the transponders which are to be read from being selected and the readout in consequence not being interfered with by reflections or undesired transponder responses from range zones which are closer or further away. Two phase modulators (PM1, PM2), one of which is arranged in the transmission path and the other in the reception path of the reading device, are driven by the same pseudo-random code, but the second phase modulator is delayed in time. They form a delay-time filter, that is to say received signals which have been reflected by a transponder or other objects are evaluated only if the sum of the delay times between the transmitted RF signal and the signal which is reflected back to the reading device is approximately equal to the delay of the modulation signal fed to the second phase modulator. For further protection against evaluation of transponder information from adjacent range zones, additional delay-time filters can be provided for these adjacent range zones and the evaluation can be carried out only in the case when no response signal is received from one of the adjacent range zones having a higher level. The device can be used in a stationary manner for reading out from transponders which are connected to moving objects, or in a mobile manner, for example on trains for reading fixed distance marks. <IMAGE>

Patent DE-4407369-A1 (DE)
Title: Transition time measurement method
Inventor: GRIESBAUM KARL
IPC: G01S17/10
Filed: 1994-03-05
Abstract: The method involves using a signals transmitter and receiver (1) with a envelope slope detector (5) and a quadrature modulator (20). The transition time is first determined approximately and finally a correction value, taking into account the exact transition time, is determined. The phase angle of the pulse is measured and the correction value derived from a fraction of the carrier frequency (fT) defined by the phase angle. The defined time point can be defined by a preceding pulse modulated pulse with the same carrier signal. The phase angles of the two pulses can determined and their phase difference formed. The correction value can then be determined from a fraction of the carrier frequency defined by the phase difference.

Patent DE-4423700-A1 (DE)
Title: Permanent-magnetic retention means
Inventor: BUTTHOFF HENDRICK
IPC: B23D33/08
Filed: 1994-06-24
Abstract: In the case of known permanent-magnetic retention means, the adhesive force is determined by the physical properties of the permanent magnets used and the coefficient of friction of the surfaces which interact with one another. The solution according to the invention is to permit the adhesive force of the permanent-magnetic retention means to be increased due to an improved coefficient of friction without changing the physical values of the permanent magnets used. This is achieved by the fact that metal or mineral grains or fibres (5) are admixed with the casting compound (4) which is required for producing the permanent-magnetic retention means, and a level of the casting compound (4) which is greater than or equal to the height of the shaped iron pieces (2) which project the furthest is aimed for. The associated increase in the contact area and the simultaneous increase in its surface roughness due to the admixed slide-inhibiting additives emerging at the surface mean that, on the whole, the adhesive force of the permanent-magnetic retention means is improved. The casting compound (4) used may have permanently elastic properties. The invention increases the resistance of permanent-magnetic retention means to displacing and slipping loads. This means that the adhesion and consequently the operational safety of mobile devices on large components made of magnetic materials can be considerably improved, even with perpendicular or greatly inclined surfaces (Fig. 1). <IMAGE>
Patent DE-4424163-A1 (DE)
Title: Cattle trough drinking height adjuster
Inventor: TASCHITZKI MARTIN VON
IPC: A01K1/02
Filed: 1994-07-08
Abstract: The adjuster consists of a spacer (2) on the ground in the drinking nipple access area which is sized and shaped to enable a beast at any stage of growth to reach the drinking nipple (1). The spacer part nearest the drinking nipple is the highest, with the height (h) in turn diminishing as the distance (a) from the drinking nipple increases. The height of the spacer and the horizontal interval between spacer tread (3,4) and nipple (1) are adapted to beast height and the length between muzzle and front legs in each phase of beast growth. The total length (1) of the spacer is adapted to the muzzle/front legs distance of a fully grown animal to reach the drinking nipple with its muzzle, with the height of the spacer decreasing over spacer length. The tread surface is cambered so the spacer as such acquires an inwards or outwards bent profile over its length, using gratings as treads to give a non-slip surface. The spacer is fixed to the trough itself and made from material proof against injury or health damage to the beast.
