Patent EP-0150976-A3 (EP)
IPC: H04S1/00
Filed: 1985-01-23
Abstract: A system for providing the effect of an extended sound­
stage comprises a pair of stereophonic loudspeakers (38A, 
38B), each having a movable or vibrational element driven by 
a pair of voice coils (44A, 46A; 44B,46B) including a principal 
or main voice coil (44A, 44B) and an auxiliary or enhancement 
voice coil (46A, 46B). The principal voice coil of each speaker 
is driven in a customary manner from one channel (70,72; 74, 
76) of a stereophonic amplifier, while the enhancement voice 
coil is driven in a reversed phase sense from the output of the 
opposite channel, and sound is effectively provided over an ex­
tended apparent source having dimensions beyond the spacing 
between the loudspeakers.

IPC: C12P1/00
Filed: 1985-12-09
Abstract: Alcohols, such as aromatic and aliphatic alcohols, are 
prepared by reducing the corresponding aldehyde with an 
alcohol dehydrogenase enzyme and with a cofactor for the 
enzyme. The enzyme is immobilised by covalent bonding to 
a support material to ameliorate the problem of its inhibition 
by the aldehyde and hence increase its active life. The 
enzyme is preferably an enzyme of Enzyme Commission 
class 1.1.1.1. such as yeast alcohol dehydrogenase (YADH) or 
horse liver alcohol dehydrogenase (HLADH). The support 
material may, for example, be agarose or an oxirane-acrylic 
polymer.

Abstract: Flow control valve (1) includes angled metering ports (37, 38 or 
35', 36') in the valve sleeve (4) for directing the 
momentum of the fluid flow against the respective valve flow metering 
edges (51, 52 or 67, 69) in a direction producing an

connected is produced every time when the contacts (1) to be 
grounded are changed, or a ground terminal block (7) having 
a great number of branched connections (7a) commonly 
formed for requirement of various circuits is produced and 
then unnecessary branched connections are removed to 
form a ground terminal block having the branched connec­
tions only required for requirement of a specific circuit to be 
connected.

Title: Fixing device with a clamping lock for releasable acting upon profiles with undercuts
IPC: F16B7/04
Filed: 1987-02-19
Abstract: A connector which can releasably couple two confronting or divergent flanges of a profiled structural member with a hollow second member has a housing which is insertable into the second member and contains two retaining arms with hook-shaped jaws projecting from the open front end of the housing. The arms are movable toward or away from each other into and from positions of overlap with the flanges before they are retracted to engage the jaws with the respective flanges. The jaws are movable to positions of overlap with the flanges by one or more displacing members and to retracted positions by one or more motion transmitting members. The displacing members and the motion transmitting members receive motion from one or more eccentrics or disc cams of an actuator which is rotatably mounted in the second member on a shaft which can be disengaged from the second member to allow for extraction of the entire connector from the second member. The shaft is movable axially relative to the actuator and has a polygonal coupling portion which transmits torque to the actuator, and one or more cylindrical portions which are rotatably journalled in a housing of the connector and/or in the second member.
