Abstract: ABSTRACT           An electronic parking meter comprising a display device, a timer and a control means operable to set the timing device in operation for a purchased parking time in response to insertion of coins into the meter.  The display device is arranged to give an initial display of purchased time, but for this display to be inhibited shortly afterwards so that a user of a previously vacant parking lot controlled by the meter cannot determine from the meter whether there is any unexpired parking time left for that lot by a preceding user.  In one form, the meter is controlled by a central processing unit and is arranged for storage in a memory of user supplied data such as vehicle registration number and parking lot identification, as well as of purchased time.  For controlling several parking lots by the meter, the meter is provided with a selector enabling the user to select a desired parking lot.

Abstract: ABSTRACT OF THE DISCLOSURE       The invention relates to a method for examining in materials such as metals in the solid state for surface defects, surface cracks or the like the properties of coating or the sur-face quality of paper.  A special application of the method is the measurement of the thickness of the surface hardening layer of steel.  With a view to preventing the rapid evening out of the temperature differences produced on the surface of the ma-terial under examination, a pulsed light beam in the visible light wavelength range is directed onto the material, whereby at least part of said light beam is absorbed on the surface of the material under examination and causes elevation of the sur-face temperature of the material under examination.  The sur-face of the material under examination that has been heated by effect of the periodic temperature variation  produced emits a pulsed infra-red radiation which is received by a sensor sensitive to infra-red radiation.

Abstract: ABSTRACT OF THE DISCLOSURE    A heat quantity meter for measuring the quantity of heat abstracted from a circulating flow of liquid by a consumption unit based upon the indirect measurement of the volume flow rate of the liquid, while maintaining a sub heat flow from and/or to the main heat flow transported by the flow of liquid, the volume flow rate of the flow of liquid being determined on the basis of the flow rate dependant heat transfer in the boundary layer of the flow of liquid at the location of the sub heat flow, by determining the temperature differential across the boundary layer and the sub heat flow passing through said boundary layer, comprising a conduit section (26) for the supply flow of liquid (24), possibly a conduit section (27) for the drain flow of liquid (25), a thermal connection (3) to at least one of said conduit sections to obtain the sub heat flow, at least one temperature sensor (22,23) on the supply conduit section or/and the drain conduit section and two additional temperature sensors (20,21) on the thermal connection on either side of the heat resistance thereof to determine the quotient of the temperature differential across the fixed heat resistance of the thermal connection and the temperature differential across the boundary layer. The thermal connection and the measuring bodies of the temperature sensors being of easily heat conducting material are taken up in a housing (30) through thermal insulation means (28,29,37,43) having in its entirety such an implementation that a linearized and reproduceable relation is obtained between the said quotient of temperature differentials and the volume flow rate.

Abstract: TABLE STRUCTURING AND DECODING            Abstract of the Disclosure A decode table made up of words arranged and encoded on a byte value/frequency of use basis for decoding phrases stored in a table.  The words making up the phrases in the phrase table are also encoded with a byte value based on the frequency of use of the words.  That is, the most popular words are coded with low byte values represented with a minimum number of bits.  The least used words are coded with higher byte values represented with a greater number of bits.  As such, storage requirements are significantly decreased.  As an example, a three word phrase including two relatively popular words may require only 11 bits made up of 3, 3, and 5 bit words.  In the decoding table associated with each word is number of word bits information.  This number of bits information is used during decoding for distinguishing the words making up the phrases.  The process of decoding a phrase includes comparing the phrase with the words in the decode table.  Since the words in the decode table are arranged or ordered by byte value, there is a likelihood of an early compare upon indexing through the decode table.  Upon a compare, the number of bits information associated with the word resulting in a compare is used to determine any phrase remainder.  If there is a remainder, the remainder is compared with the decode table to obtain a match.  The compare/remainder determination sequencing continues until all words in the phrase have been decoded.

Abstract: ABSTRACT A torsional vibration absorber device is positioned between two relatively rotatable members.  A coupling member has a projection engaging a camming surface on one of the members, the camming surface being slanted circumferentially with respect to the axial direction.  A wet type friction clutch is interposed between the coupling member and the other rotary mem-ber and is urged in the direction of its engagement upon axial movement of said coupling member, and a spring opposes such movement of the coupling member.  An hydraulic oil chamber connected to atmosphere via an orifice decreases in volume upon axial movement of the coupling member.

Abstract: A B S T R A C T     SUCTION ANCHOR AND METHOD OF INSTALLING             A SUCTION ANCHOR     A problem which sometimes occurs is that the plug of bottom material which enters the interior of a suction anchor during installation of the anchor may disturb the pumping process, since the reduced pressure may cause expansion of the plug, the result being that the anchor does not reach the desired depth in the water bottom. According to the invention this problem is solved by removing at least the upper part of the plug from the interior by introducing water into the interior, forming a mixture of bottom particles and water and removing the mixture formed from the interior.           The invention relates as well to a suction anchor suitable for carrying out the method according to the invention.

Abstract: Abstract of the Disclosure In manufacturing synthesis gas by partial oxidation of slag-rich fuels, the slag must be removed from the crude gas in order to avoid clogging of the gas generator; at the same time it is desirable to recycle the soot agglomerated with slag into the synthesis gas reactor.  The soot-slag agglomerates are scrubbed out of the gas by water. The suspension of agglomerates is processed according to the invention in a shearing force generating disperser, and then separated by means of an organic solvent.  The organic solvent absorbs the low-slag soot which is recycled into the synthesis gas reactor.  Soot-free slag is drained off through the aqueous phase, and conveyed to where it will be processed further.

Abstract: ABSTRACT There is described an improved liquefaction process by which coal is converted to a low ash and low sulfur carbonaceous material that can be used as a fuel in an environmentally acceptable manner without costly gas scrubbing equipment. In the process, coal is slurried with a solvent, passed through a preheater and at least two dissolvers in series in the presence of hydrogen-rich gases at elevated temperatures and pressures. Solids, including mineral ash and unconverted coal macerals are separated from the condensed dissolver effluent. In accordance with the improved process, fresh hydrogen is fed to each dissolver and the entrained gas from each dis-solver is separated from the slurry phase and removed from the reactor system before the condensed phase is passed to the next dissolver in the series. In accordance with another process, the feeds to the dissolvers are such that the top of each downstream dissolver is used as a gas-liquid separator.
