Abstract: TEAT DILATOR              ABSTRACT OF DISCLOSURE     A dilator for a teat of a dairy cow operates to facilitate the flow of fluid from the teat.  The dilator has a body having a passage adapted to be positioned in communication with a duct of the teat.          An elongated tubular member extends from the body into the duct.  The tubular member has a passage allowing the flow of fluid through the dilator.  A one-way valve mounted on the body allows the flow of fluid out of the dilator and restricts the entrance of external foreign substances back into the passage and duct of the teat.          The valve has flexible side walls terminating in normally closed lips.  A slit mouth is located between the lips.          The slit mouth can be opened to facilitate the dispensing of medicinal compounds into the teat and udder of the mammal.  An inserter having a rod extended through the one-way valve and tubular member is used to place the dilator in the teat duct and duct outlet, with the one-way valve located at the terminal end of the teat.

ABSTRACT OF THE DISCLOSURE       A coin-operated lock for a trolley system, especially shopping trolleys and luggage trolleys, which lock is adapted for mounting on a trolley. The coin-operated lock is arranged for release of a trolley when a coin is inserted as well as for repayment of the amount paid when the trolley is returned. The lock has two blockable keyholes, either of which is arranged for acceptance of a separate key, one of which is fixed to the same trolley as that on which the lock is  mounted. The lock is further arranged in such a way that when a coin is inserted, one keyhole is released for acceptance and securing of the said key fixed to the same trolley, that the other keyhole secures a key belonging to another trolley or a coupling unit, that the other keyhole is released for release of the other key when the said key fixed to the same trolley is inserted in the former keyhole, and that the former keyhole is released for release of the said key fixed to the same trolley and secured therein and for return of the coin when the other key is inserted in the other keyhole.     The keys (4) designed for insertion in keyholes (2 and 3) have interacting blocking means (2) arranged as codification units (13, 14, 15, 16) which only permit insertion and withdrawal respectively of a key if the code of this key fits together with the code of the other key so that only keys fitting together can be moved relative to each other for insertion and withdrawal purposes respectively.          The use of different codes for the trolleys of different enterprises can thus prevent trolleys from different enterprises being coupled together.     Fig. 2.

Abstract: A SYSTEM FOR REDUCING THE RATING REQUIREMENTS     OF STATIC COMPENSATOR COMPONENTS AT        HVDC INVERTER STATIONS         ABSTRACT OF THE DISCLOSURE         In a static compensator for use with HVDC converter stations, the rating requirements of the compensator transformer, thyristor switches for switched capacitors, compensator capacitor banks and their tuning reactors, are reduced.  The compensator is arranged to regulate AC system voltage in accordance with a first reference.  The voltage on the secondary bus, i.e., the secondary winding of the compensator transformer, is regulated in accordance with a second reference and this overrides the regulation of AC system voltage for larger leading currents supplied to the AC system.  These larger leading currents are not required as they represent leading currents which exceed unity power factor operation by a predetermined amount.  Being able to limit the leading current in this manner enables lower rating requirements.

Abstract: ABSTRACT OF THE DISCLOSURE      A procedure for measuring the flow velocity of a sus-pension by ultrasonic echo pulse technique.  In the proce-dure, two or several ultrasonic transducers located at a dis-tance from each other are placed on the surface of the pipe subjected to measurement.  From the transducers an ultra-sonic pulse is emitted through the pipe and an echo of the ultrasonic pulse is received after a time determined by the measuring depth.  The echo pulses are received and a low fre-quency signal contained in them, caused by fibres or other particles in the suspension, is amplitude-detected.  In the procedure is used a second or later echo from the rear wall of the measuring pipe in case a received echo is masked by the transmitted pulse.  The signals derived from the trans-ducers are compared utilizing a correlation technique and in this way the flow velocity of the suspension that is to be measured is determined.

Abstract: PORTABLE HEATER WITH INTEGRATED CONTROL SYSTEM          ABSTRACT OF THE DISCLOSURE:    A heater including a generally cylindrical shell defin-ing its housing arranged in a very closely spaced relation to the outer periphery of its combustion chamber assembly and its fan device as it bounds a plenum chamber therebetween.          The combustion chamber assembly has its discharge end adjacent the discharge end of the shell.  The relative configuration of the outer peripheral surface of the combustion chamber assembly and that of the discharge end portion of the shell creates therebetween a passage through which the fan device, on en-ergization thereof, produces a very high velocity flow of a thin layer of air which, on discharge, is throttled and ab-ruptly and sharply driven into the center of the flow from the assembly.  The effect of this is to moderate and influence a relative uniformity of the temperature of the discharge and rapidly project it outwardly of and considerably beyond the heater.  A further consequence is the creation of such a head of pressure in the plenum chamber as to produce a greater and more uniform pressured flow of air into and about the com-bustion chamber.  The whole provides a heater which for a given size has a heating capacity substantially greater than heretofore.  The heater also features an integrated control system giving it an uncluttered interior and insuring, to a significant degree, against failure and malfunction.  A pre-ferred housing for the heater is a multi-part shell the form of which eliminates need for intervening gaskets.
