Patent EP-0070633-A3 (EP)
Title: Electrical switching circuit for a multi-phase load
IPC: H02P7/00
Filed: 1982-06-28
Abstract: An electrical switching circuit for a multi-phase a.c. supply uses semiconductor rectifier switches SCR1 to 5 to reversibly switch power to a multi-phase electric motor so that the motor can be run in a forward or a reverse direction. The SCRs are provide in two sets, one for switching power to forward run the motor, and the other set for reverse running of the motor. Inductor elements  DELTA L are connected in series with the SCRs. The inductor elements comprise coils which include a non-linear permeability core, for example of ferrite or permalloy, which are operative to suppress voltage transients at switch on of the motor. These transients would otherwise produce spurious firing of the SCRs and could produce a short circuit across the input phases of the a.c. supply. The circuit is used in a valve actuator. Improved torque limit switches and position limit switches are disclosed, which operate a low voltage and which use Reed and wall effect switches.

Abstract: A method of manufacturing a foodstuff or a foodstuff 
precursor, said method comprising steps of forming a liquid 
protein composition with the desired ingredients, modifying 
the protein using a coagulating enzyme but without allowing 
coagulation, passing the liquid so modified along a flow path 
while adjusting the pH and heating the liquid to cause 
coagulation of the protein into small curd centres within the 
flow, separating the coagulated protein from the remainder 
of the liquid, mixing the coagulated protein with additives, if 
any, and forming the resultant mix into a foodstuff or

IPC: G01H9/00
Filed: 1984-12-20
Abstract: An orthoscopic ultrasonic imaging system which in­
cludes an acoustic transducer for insonifying an object to be 
inspected and an improved liquid crystal detector cell for 
receiving an imaging beam from the insonified object and for 
displaying a visible image. An electric, magnetic or acoustic 
biasing field is applied to the liquid crystal cell for raising the 
cell to an acousto-optic threshold which permits detection 
and display of low intensify imaging signals. The cell 
surfaces which contact the liquid crystal material are treated 
so as to preferentially align the liquid crystal molecules for 
situations where electric or magnetic field biasing is used. 
Preferential alignment means that the longitudinal axis of the 
molecules are on average parallel to each other as indicated 
by the bulk director. Low intensity, acoustic fields [e.g. less 
than 10⁻³ w/cm²] can be detected and displayed, and the 
object being examined can be insonified with low intensity 
ultrasonic beams.

IPC: F16F15/26
Filed: 1985-11-14
Abstract: To additionally reduce the noxious emissions of motor 
vehicles, the gasoline or diesel engines are splitted into a 
primary and a secondary engine, both having own partial 
crankshafts.  
     The primary engine in conventionally used, and it 
drives the vehicle auxiliaries by a novel engine cross-shaft, 
while the secondary engine is automatically started and 
clutched-in for higher loads, and automatically separated 
and stopped under no-load conditions.  
     The clutching-in and separation of the secondary 
engine is performed by a novel clutch between the two 
partial crankshafts, controlled by the accelerator pedal with­
out the driver's help, which also effects an automatical 
synchronization of the crank positions of the partial crank­
shafts.  
     An additional hand-switch can exclude the clutching-in 
of the secondary engine for motor-queuings.  
     The split-engine establishes a whole engine family, 
contributes a multiplicative reduction of noxious emissions, 
saves additionally fuel, and enables economy-priced engine 
optionals.
