Title: Bioassay for toxic substances bioassay for toxic substances
IPC: C12Q1/25
Filed: 1986-12-24
Abstract: An assay method is disclosed to test for the presence of toxic substances in environmental samples. The assay uses a suspension of mitochondrial membranes carrying enzymes which can be driven by reverse electron transfer to reduce NAD+ to NADH. The competency of the mitochondrial membrane to accomplish this reduction in the presence of the environmental sample is measured spectrophotometrically to test for toxicants.

Title: Method and device for making concrete in a tunnel
IPC: B28C9/04
Filed: 1987-11-05
Abstract: A concreting train consists of a plurality of wagons supporting a mixer, a multiple conveyor arrangement and separate containers for cement and aggregate. A container for cement has at least one integrated conveyor worm. All container wagons are provided with inclined conveyor belts which extend below the containers and overlap one another. On separate pathes aggregate and cement are supplied into a housing of the mixer wagon. The housing is supported on a weighing frame in order to additively weigh the mixing components. The housing contains a mixing shaft operatively connected with a drive motor. The housing is mounted for reciprocating movement along an inclined angled track in order to lift the housing on a higher level for discharging the concrete into a hopper of a concrete pump. The concreting train is adopted to be used in narrow tunnels in order to provide a multiplicity of small batches of high quality concrete in very short periods of time at the face, whereby quality and consistence can be quickly varied.

Title: Water boiler volume compensating device for a hot water boiler
IPC: F24H1/18
Filed: 1987-12-24
Abstract: In the device, the water to be heated can be heated and stored in a water tank (5) which has a cold water supply and a hot water delivery. 
<??>In such hot water boilers, a thermal expansion of the water takes place during the heating period. In a closed water tank, this renders volume compensation necessary to avoid a harmful rise in pressure. 
<??>For the purpose of volume compensation and in order to avoid expansion water emerging in drip form at the consumer tapping point, there is connected fluidically to the water tank (5) a bellows (11) which can be extended via a pressure-controlled or temperature- controlled lifting device (13, 13') according to the temperature- conditioned change in volume of the heated tank water. 
<??>The volume-compensating device is suitable in particular for so- called open hot water boilers.

Abstract: An improved jitter detecting method and an appara­
tus thereof, for detecting a jitter generated in a repro­
duced video signal of a VTR or video disc wherein a 
frequency-modulated carrier of a video signal is recorded by 
synchronizing the leading edge of a sync signal with the 
phase of the forefront carrier of a constant frequency 
carrier train corresponding to a sync tip for every 
horizontal period at the time of a frequency-modulation, and 
from the reproduced frequency-modulated carrier the 
phase-reset constant frequency carrier train is abstracted 
as a reference burst signal, thereby to be capable of 
removing a time-base error by detecting a specifie 
zero-crossing timing of the abtracted carrier burst through

Title: Circuitry for a connection component in a time division multiplex digital telecommunications network
IPC: H04B1/58
Filed: 1988-06-09
Abstract: A circuit arrangement for a module in the line-connection section of a digital time-multiplex telecommunication network is disclosed. The module contains, among other things, a transverse filter to perform a two-wire/four-wire conversion and is connected through a transformer to the wires of a subscriber line. In order to compensate for phase distortions caused by reflection of signals from the transformer back to the module, the corresponding signals coming from the module are subjected to an equal and opposite phase pre-distortion. This optimizes the hybrid circuit attenuation.

Title: Active four wheel steering system for automotive vehicles
IPC: B62D6/02
Filed: 1989-02-11
Abstract: An active four-wheel steering system for motor vehicles, with steering arrangements for the front and rear wheels is described. These arrangements act as a function of driving-condition variables fed to an electronic control unit. A variable steering-lock angle ratio with respect to the front wheels is set, a first function converter of the control unit being supplied with the input signal relating to the steering-wheel angle by a steering-wheel angle sensor and with the further signal relating to the vehicle speed by a speed sensor. This function converter produces a first output signal for the lateral acceleration, which is fed as an input signal, together with the further input signal relating to the vehicle speed, to a second function converter. To allow for a change in the driving speed, the output signal relating to the lateral acceleration is fed, together with a signal derived from the change in the driving speed, to the third function converter. This input signal, calculated in the first function converter, and the input signals relating to the change in speed, calculated in the third function converter, are converted into an output signal for an additional rear-wheel steering angle, which is superposed on the output signal for the rear-wheel steering angle. The sum of these output signals is fed as steering-angle signal to the control unit for the purpose of controlling the hydraulic steering arrangement for the rear wheels. <IMAGE>

Title: A vertical jump exercise apparatus
IPC: A63B21/04
Filed: 1989-05-30
Abstract: A vertical jump exercise apparatus is proposed to train and condition participants in sports demanding a high degree of vertical jumping ability. Elastic cords (20) fastened to the waist of the user provide a nearly constant resistive force, thereby simulating increased body weight to strengthen leg muscles and to improve motor reflexes. Generation of the nearly constant force is accomplished by directing one or more of the elastic cords beneath or away from the exercise area (12), thus allowing use of an increased length of cord. Directional control for the jumper, cord following to prevent fouling of the cord, and reduced friction are provided by movable tracking assemblies (40) that may pivot or move linearly and may be provided with pulleys. The tracking assemblies may also serve as force imbalance indicators for the elastic cords.

IPC: G06F12/06
Filed: 1989-11-30
Abstract: In order to more effectively use read only memory space of a 
personal computer system, ROM code is selectively located or mapped 
to either an address boundary which is an even or odd integer 
multiple of one half the capacity of the read only memory device in 
which the ROM code is stored. The ROM code is stored in the read 
only memory device in two fields. In a first field, the ROM code is 
broken up into two segments, and the first segment precedes the 
second segment. In the second field, the same two segments are 
stored, but the second segment is stored preceding the first 
segment. A register, for storing page select bits, provides an 
input to an address decoder and an input to an adder, which adds 
unity to the contents of the register and provides its output to 
the address decoder as well. Accordingly, the address decoder will 
respond to either the page which is identified by the page select 
bits or the page following the identified page. The LSB of the page 
select bits is used in addressing the read only memory device to 
select between the first field (selected when the LSB is zero) or 
the second field (selected when the LSB is unity).

both, (c) polyfunctional, polymerizable, non-acryloxy-­
functional ethers, (d) at least one radiation sensitive 
initiator and, preferably, (e) a monofunctional monomer. 
When the surface of a substrate coated with the cured 
coating composition is immersed in a colored dye bath 
for a sufficient period of time, the coating absorbs or 
transmits to the substrate a desired amount of dye.
