Patent EP-0088626-A3 (EP)
IPC: G05D13/62
Filed: 1983-03-08
Abstract: A closed-loop system for precisely regulating the speed of 
an electrically driven rotating body. A tachometer rotor (53) 
mechanically linked to the rotating body is provided with p 
"teeth" (55) around its periphery. A sensor (57) produces a 
pulse signal upon passage of each of these teeth, to generate a 
cyclic tachometer signal having a frequency p times the 
frequency of rotation. A tachometer counter (5) counts this 
signal and produces a single output pulse after every n x p 
pulses from the sensor, such that the same one of the p teeth is 
responsible for triggering each of the successive output pulses, 
and variations in spacing between teeth do not cause variations 
in the period of the counter output.  
     A high frequency clock (17) is counted by a second coun­
ter (14) which transfers its count to a storage register (23) and 
resets upon each pulse from the tachometer counter (5), such 
that the count held by the storage register is a continuously up­
dated, highly accurate digital respresentation of the period of 
the rotating body. A period comparator (39) derives a speed 
control signal which is proportional to the inverse of the dif­
ference between the count and a digital speed command signal 
representative of the rotational period at the desired rotational 
speed.

Abstract: A slab (6) is joined by means of pillars (2, 3, 4, 5) to the 
top of a buoy (1). The weight of the entire unit and the 
volume of the buoy (1) are such that the level of free-floating 
(7) of the unit is between the top and the bottom of the buoy 
(1). The height of the pillars (2, 3, 4, 5) is greater than the 
expected maximum height of waves in the region where the 
unit has been installed. The unit is anchored by means of 
ropes (12, 13, 14, 15) under tension so that it is kept 
submerged to a level (20) which is above the top of the buoy 
(1) and below the slab (6). At this position and for loads up to 
the difference of the buoyance of the buoy minus the weight 
of the entire unit and minus the weight of the ropes (12, 13, 
14, 15) the unit remains immobile despite the existence of 
waves or fluctuations of the load it is bearing.

Title: Colorimetric immunoassay on solid surface, dipstick thercolorimetric immunoassay on solid surface, dipstick therefor and its preparation efor and its preparation
IPC: G01N33/535
Filed: 1984-05-04
Abstract: The inventive concept provides an immunoassay using an enzyme label, in which the detection of the unknown substance is performed colorimetrically directly upon a solid surface. Preferably, the surface is an impermeable surface of a dipstick. To detect antigen in a biologically derived fluid sample, a dipstick containing bound antibody may be contacted with the sample and with a soluble enzyme-labeled antibody, to cause the antigen to bind to both the immobilized antibody and the labeled antibody on the surface. After separation of unreacted reagents, the solid surface is contacted with a substrate which converts from a soluble form to an insoluble colored form in the presence of the enzyme and deposits upon the surface of the solid surface. The solid surface is separated from the solution. The sandwich immunoassay technique may also be employed to detect antibody in the sample by reversing the roles of the antigen and antibody. The system is also applicable to a competitive binding technique. The invention further includes a colored dipstick produced by this means.

Title: Method for expelling a batch of dewatered laundry from the press container
IPC: D06F47/00
Filed: 1985-03-01
Abstract: The press container of a wash press sits on a porous press plate. Because of the high press pressure of the press piston head the fabrics of the wash are partially forced into the holes of the press plate. In order to remove the pressed wash safely from the press plate, the pressed wash is raised somewhat from the press plate when the press container and press piston are simultaneously raised, first into a middle position in which the press piston head remains, while the press container is raised further. The wash loosened in this way can be safely slid laterally from the press plate.
Patent EP-0179541-A3 (EP)
IPC: G01F1/66
Filed: 1985-03-29
Abstract: The disclosed meters employ mechanical radiant energy 
to determine the flow velocity of flowing material. Mechan­
ical radiant energy is propagated through the flowing ma­
terial in two directions to permit the material to cause a 
variance between the average velocity at which the energy 
travels in a first direction from the average velocity at which 
the energy travels in a second direction. Since the variance 
in average velocities is due to the movement of the material 
and is related thereto, the variance, and the difference in time 
required for the energy to propagate through the material, 
can be used to determine the flow velocity of the material. 
One embodiment employs the following equation to calcu­
late the flow velocity: 
  
where t u  and t d  represent the time required for the energy to 
traverse the path in each direction. Another embodiment 
transmits energy pulses in each direction in groups of at least 
two pulses and imposes a time delay between the time each 
pulse finishes propagating along the path and the transmis­
sion of the next pulse. The time required for the energy to 
propagate along the path in each direction is determined 
from the time required to transmit along the path all the 
energy pulses of each group and the total duration of the 
time delays. A further embodiment examines the received 
energy and determines whether the level of the transmitted 
energy should be altered to improve signal processing. A 
further embodiment assumes that the energy has reached 
the end of the path, and is therefore able to determine the 
time required for the pulse to traverse the path, by defining 
a receive point which is a predetermined point at which the 
received signal crosses a reference axis following the peak 
level of the signal. The preferred embodiment combines all 
the features identified above.

Abstract: A Doppler radar system for a vehicle providing driver 
warning, vehicle brake application and air bag deployment. 
The system produces voltage level inputs directed to the 
distance and approach rate to an object, vehicle speed and 
driving monitor inputs, such as steering angles, turning rates, 
braking, and acceleration/deacceleration. These voltages are 
properly weighted as to their importance. These weighted 
instantaneous input voltages are summed. The summed vol­
tage is then compared with a predetermined voltage level 
dividing safe and danger zones. If the summed level falls 
within the safe zone, the radar system produces no output 
signals. If the summed voltage level falls within the danger 
zone, the radar system produces audio warning signals and if 
impact with an object is eminent vehicle braking signals are 
then produced. The invention further includes an air bag de­
ployment feature. A vehicle air bag is deployed when the 
vehicle speed exceeds a pre-determined value and the dis­
tance to impact is within a predetermined distance. The air 
bag deployment and audio and braking functions are inde­
pendent.
