Abstract: A reduction of the diameter is carried out in the pipe (5) in a thread-free manner. The in-pipe reduction (6) comprises a cylindrical hollow body (7) with two sealing rings (8) and four bores (9) for receiving arresting bolts (10). Plugged in the cylindrical hollow body (7) is a tube part (12) with an integrally formed flange (13), on the one hand, and a thread, on the other hand.

Patent DE-3917374-A1 (DE)
Inventor: KULA MARIA-REGINA
IPC: C12P13/00
Filed: 1989-05-29
Abstract: The preparation of (S)-cyanohydrins by reaction of the corresponding oxo compounds with hydrocyanic acid can be achieved enzymatically with the aid of oxynitrilase (4.1.2.11) from Sorghum bicolor. This is preferably carried out in aqueous medium at pH values below 6.0, in particular below 4.5, in order to suppress competing chemical reactions and racemisations. The reaction temperatures are, in particular, between -5 DEG C and +50 DEG C. Of particular interest is the reaction of aromatic aldehydes, specifically benzaldehyde and its derivatives, and the generation of aldononitriles by reaction of aldoses, especially of sugars with 3 to 9 carbon atoms, with hydrocyanic acid.

IPC: D21F3/02
Filed: 1989-08-10
Abstract: The press-belt filter has an arcuate entry gap 6 in the region of an arcuate sliding guide 3 which is formed by a perforated plastic shell. This plastic has very favourable sliding properties. The arcuate entry part corresponds approximately to a circle sector of 15 DEG . The frictional stresses along the screening belt running on the sliding guide are consequently not very high. <IMAGE>

Title: Air-air heat exchanger - with plastic clamping blocks for corrugated parallel tubes
Inventor: OBERSCHMID RAIMUND DR RER NAT
IPC: F28F9/14
Filed: 1989-08-29
Abstract: An air-to-air heat exchanger, specially for transferring the heat from outgoing air of byres to the cold ingoing air, is made up of corrugated tubes (1) which are held in a frame (8) with sets of clamping blocks (3) at each end. These blocks are made of die cast metal, stainless steel, glass fibre reinforced plastic injection mouldings or of wood. They have several semi-circular recesses for the tubes on both sides. The distance between these blocks can be varied within 0.5-2% of the nominal distance to facilitate the assembly and the raster can be filled with cast epoxy resin. The separate blocks (3) can also be replaced by rectangular plates, again with a grid of bores to suit the tubes (1). The distance can be adjusted by bending the frame sections (16) or by a set of suspension springs. ADVANTAGE - Such heat exchangers are simpler to make and to assemble.

Title: Applying transfer to surface of can - involves turntable to transport cans to work stations
Inventor: SCHWYN BERNHARD ANDREAS
IPC: B41F16/00
Filed: 1989-10-26
Abstract: Motifs are printed on the outside surfaces of metal cans first coating the can surface with a substance with an affinity for the colouring matter in the transfer.

This process is carried out by a machine with a turntable (11) which is provided with mandrels (19) to receive the cans.  The  turntable rotates with a stepwise motion and transports the cans from the loading station (13), to the transfer applying station (14), the heating station (15), the station (16) where the  transfer backing strip is removed, and finally to the unloading station (17). USE - Applying designs etc. to surfaces of metal cans.

Title: Protection circuit for power MOSFET - has switch across gate-source and responsive to drain and input voltages
Inventor: SOMMER PETER
IPC: H03K17/082
Filed: 1989-11-02
Abstract: A switch (5) is between the gate and source of the power MOSFET (1) and is switched on if the drain-to-source voltage exceeds a preset value which is greater than the voltage for nominal current flow. Between the gate terminal (G) and the input terminal (23) is a controllable resitance (2) which is so controlled by the controllable switch as to assume a low resistance when the switch is off and a high resistance when the switch is on. Pref. the controllable resistance (2) is a depletion FET (8).  A temperature sensor (18) may contact the power MOSFET, and when this reaches a set temperature the sensor gives out a signal which also causes the switch (5) to switch on.  A delay (19) may be between the input terminal and the controllable switch (5). ADVANTAGE - Protection against load short circuit while allowing high operating currents.

Title: Remote inconsistency or foreign body location - uses opto-thermal-acoustic technique to measure surface oscillation and identify target locations
Inventor: MANTEL JUVAL DR ING
IPC: G01S17/86
Filed: 1990-02-12
Abstract: The opto-thermal-acoustic remote locating technique, to detect inconsistencies and unwanted solids in the ground or in slurries uses laser pulses to generate a sound level at the surface. Optical velocimeters receive the sound inconsistency reflections through surface oscillations from the bodies detected by the optical velocimeters. The laser light source is strongly concentrated by amplitude and duration or other modulation to accelerate the evaluation of the signal and to improve the signal noise gap. Additional sensors can be used to fix the sound, such as capacitative probes which receive the surface oscillations to give a better noise ratio on signal processing. The signal processing uses a single- or multi-dimensional cross correlation function or pattern recognition.

Patent DE-4007103-A1 (DE)
Title: Sabot for sub-calibre projectile
Inventor: ROSSMANN WINFRIED
IPC: F42B14/06
Filed: 1990-03-07
Abstract: A sabot has a forwardly open air compartment with an inturned lip. The compartment is pref. cup-shaped, most pref. tulip-shaped, and has borings through its wall and apertures spaced around the peripheral region of the lip. The compartment is in a front zone of the sabot, and radial through-borings in the lip reduce drag forces acting on the base of the compartment to permit neat and unimpeded separation of sabot segments from the projectile after leaving the barrel, The borings and free cross-sections reduce air resistance so that load on the connection zone between the rear zone and compartment is reduced and the connection zone can be of smaller diameter, this reduces wt.
