Title: Inductance and capacitance charge pump circuit for driving power mos transistor bridges
IPC: H03K17/082
Filed: 1989-06-08
Abstract: The circuit comprises a tank capacitance (C) and a charge 
circuit supplied with the same voltage (Vs) as the bridge (M1, M2) and 
comprising an inductance (L) and a control transistor (T). 
There is also provided a control circuit (CC), which comprises 
an oscillator (OSC) controlling the periodic switching of 
control transistor (T) and a comparator (CP1) which controls 
the momentary clamping of control transistor (T) in the 
condition wherein the charge circuit is interrupted when the 
difference between the voltage across capacitance (C) and the 
power supply voltage exceeds a preset maximum value and the 
unclamping of the same transistor (T) when such difference 
falls below a preset minimum value. A further comparator (CP2) 
similarly clamps control transistor (T) if there is an excess 
current in the transistor itself.  
     The generated voltage (Vp), which is higher than the supply voltage 
(Vs), controls, through a driver circuit (DS2), the gate of a power MOS 
transistor (M2).

Title: Low calorie fat mimetics
IPC: A23L1/308
Filed: 1989-01-19
Abstract: Novel fat mimetic compositions are disclosed as reduced 
calorie food components. These compositions comprise complex 
polyol esters elaborated with fatty acid residues, and/or 
residues of esters or ethers having an acid function. The 
complex esters are partially broken down in the body to yield 
at least two types of aliphatic digestion residues which are 
more hydrophilic than the original complex polyol ester 
substrate. The majority by weight of the digestion residues 
will be non-hydrolyzable by the normal digestive processes, 
while a minor amount by weight may be susceptible to facile 
cleavage by the action of digestive lipase. The fat mimetic 
compounds are useful as replacements for fats and oils for 
most food applications.

Title: A particle agglomeration process
IPC: B09B3/00
Filed: 1989-01-20
Abstract: A method is described for utilizing metal 
containing by-products or waste products of metallurgical 
processes. The metal containing particles, or dust 
originating in metallurgical processes are agglomerated with 
a combustible agglomerating agent, and are usually charged 
to smelters, converters, or similar high temperature 
installations for the recovery valuable metals present in 
such dust particles. The agglomerates are obtained by 
mixing the dust particles with an amount of combustible 
agglomerating agent. The amount of agglomerating agent used 
for producing the agglomerates is related to the bulk 
specific gravity and the particle size range of the dust 
particles. The combustible agglomerating agent of this 
method, such as hydrocarbon wax, tar, bitumen, distillation, 
residue and similar combustible material, is solid at 
ambient temperatures.  
     In the preferred embodiement the combustible 
agglomerating agent is mixed with the dust particles at a 
temperature above the melting point of the agglomerating 
agent, the hot mixture is subsequently allowed to cool in a 
 
 
mould and compacted. The cooled compacts are removed from 
the mould before utilization. In a particular form of 
application of this invention the mixture is allowed to cool 
in combustible containers and may subsequently be utilized 
as compacts bonded to their containers.  
     The agglomerated particles may be used for 
non-combusted purposes as well, such as support structures 
or filling in cavities, or merely for protecting the 
environment from loose dust particles of metallurgical 
origin.

Title: Magnetically-damped, testable accelerometer
IPC: G01P15/00
Filed: 1989-02-20
Abstract: An acceleration sensor comprises a housing 
having a magnetically permeable element, such as a steel 
washer, secured thereto proximate with an end of a 
cylindrical passage formed therein; a magnetic sensing 
mass in the passage which is displaced in response to 
acceleration of the housing from an initial position 
within the passage proximate the steel washer to a 
second position within the passage when such 
acceleration overcomes the magnetic bias of the sensing 
mass towards the steel washer; a pair of electrically 
conductive rings encompassing the passage so as to 
provide magnetic damping for the sensing mass during the 
displacement thereof; and a pair of beam contacts 
projecting from the housing into the passage so as to be 
bridged by the sensing mass when the sensing mass is 
displaced to the second position within the passage. 
The accelerometer further comprises a pair of 
oppositely-wound electrical coils encompassing the 
passage proximate the initial position and the second 
position of the sensing mass therein, respectively. 
Upon the delivery of a direct current to the coils, the 
sensing mass is magnetically biased to the second 
position within the passage, whereby the beam contacts 
are bridged by the sensing mass to confirm the 
operability of the sensor.
