Title: Signal diversity arrangement for mobile reception
Inventor: LINDENMEIER KARL-HEINZ G
IPC: H04B7/08
Filed: 1987-12-02
Granted: 1992-01-07
Abstract: ABSTRACT       "Signal diversity arrangement for mobile reception"         The invention relates to a signal diversity arrangement for a mobile reception, comprising a receiver and a diversity processor, which receives the input signals and applies a differ-ent input signal to the receiver when interference occurs.  The diversity processor comprises an interference detector operating in the analog mode and a comparator, to whose first input is applied the output signal of the interference detector and to whose second input is applied a suitably set voltage Vl.  The comparator shows on its output the occurrence of interference by way of a binary signal when the threshold voltage V at the second input is exceeded.  No less than one integrator is available hav-ing a discharging time constant, to whose input is applied a sig-nal derived from the interference signal and whose time of inte-gration is equal to the switching interval of one of the input signals and whose output signal is added to either the interfer-ence signal at the first comparator input such that when the interference is increased the total voltage at the first input of the comparator is increased also, or the output signal is applied to the second comparator input such that the threshold voltage is lowered when the interference rises.  In the case of a series of integrators whose inputs each receive a signal derived from the interference signal of the associated input signal, the output signals of these integrators are each time applied to one of the comparator inputs and the threshold voltage V is changed each time in accordance with the interference signal during the switching interval.

Title: Roller conveyor
Inventor: KATSURAGI HIFUMI
IPC: B65G13/07
Filed: 1988-04-20
Granted: 1991-07-16
Abstract: Abstract Free rollers for transferring objects to be transferred, and a driving device for rotating the free rollers are supported by a support frame.  A plurality of support frames are attached to a main frame so that their positions can be changed lengthwise of the main frame.  The roller pitch can be changed as desired by changing the attaching position of the support frame.  Thereby, the number of units each consisting of a free roller and a driving roller is reduced in accordance with the shape and length of objects to be transferred.  Thus a cost reduction of the entire conveyor and a compact design of the free roller driving device can be attained.

Title: Process for rehabilitating internally reinforced concrete by removal of chlorides
Inventor: VENNESLAND OYSTEIN
IPC: C04B41/72
Filed: 1989-09-06
Granted: 1996-03-12
Abstract: A process for rehabilitation of internally reinforced concrete which comprises the temporary application of an adherent coating of an electrolytic material to surface areas  of  the  concrete.    Distributed  electrode  means, preferably a wire grid, is embedded in the adherent coat-ing.  Voltage sufficient to develop a current of about 1-5 amps/m  is  applied  between  the  reinforcement  and  the distributed electrode, to cause migration of chloride ions from the concrete into the electrolytic coating.  When the chloride content of the concrete has been reduced to a desired level, the voltage is discontinued and the electro-lytic coating and distributed electrode are removed.   A highly preferred material for the adherent electrolytic layer is cellulosic pulp, premixed with water or other solution  (such as calcium hydroxide)  in a nozzle and sprayed  onto  the  surface  of  the  area being  treated.          Desirably, the distributed electrode is formed of a ferrous material reactive with chlorine, to minimize the release of free chlorine gas into the ambient.   Particularly for tensioned reinforcement, the process monitors polarization of the tensioned steel to prevent hydrogen embrittlement.

The methods comprise: (a)     sampling at least one organism in order to determine whether it has been chronically exposed to a sublethal concentration of one or more pollutants in its environment, under sampling conditions that do not induceany additional heat shock protein (hsp) response in the organism; (b)     obtaining a sample of cells or secretions of said organism, suspected of having elevated levels of heat shock proteins and solubilizing the heat shock proteins in the sample; and (c)     measuring the concentration of a heat shock protein selected from hsp 70, hsp 60 and ubiquitin, in said sample. The invention also provides methods for evaluating biological damage due to chronic exposure to a sublethal concentration of one or more pollutants comprising detecting chronic exposure of the organism by the above method and then comparing the measured concentration of hsp to a predetermined standard calibration curve which correlates hsp concentration with physiological impairment of growth or reproductive processes, and kits for carrying out the methods.

Abstract: A road testing apparatus has a framework extending over a test portion of road pavement and has tracks with upwardly curved ends along which wheels of a trolley unit roll so that the trolley unit decelerates as it approaches an end position to cause kinetic energy to be transformed into potential energy and when return motion trolley commences the potential energy transforms back to kinetic energy. The trolley unit has a pivotally mounted base structure carrying a test load and a pair of road wheels which are mounted so as to be steered by the trolley as it progresses in a forward direction along the test pavement, additional wheels of the trolley running up an end portion of the track to lift the road wheels off the road surface as the end position is reached. A telescopic linkage latches into engagement at this end position to retain the road wheels in an elevated position relative to the trolley so that, during return motion, the road wheels can continue to rotate in the same direction but engage on the bottom of a base plate structure of the framework to drive the trolley in the reverse direction, the latch arrangement being released when the trolley reaches the opposite end position to permit a further cycle of operations.
