Abstract: ABSTRACT OF THE DISCLOSURE   A method and apparatus for removing defective railroad ties from the right-of-way in one piece and without dis-turbing the elevation, cross-level and line, of a track system.  The method is carried out by first removing the tie plates from an individual tie to be replaced; forming a trench underneath the tie by the use of laterally directed scarifiers while retaining the tie in its normal position and restraining the tie against movement longi-tudinally of the track system so as to displace ballast material from underneath the tie to the next adjacent crib; applying a downward force to the top of the tie to be removed  and withdrawing the tie from one or the other end.  The apparatus for performing the method includes a plurality of laterally spaced-apart scarifier means adapted to be rotated about a common axis that is parallel to the longitudinal axis of a tie to be removed; a restraining means to retain the tie in its normal position while the scarifiers are rotated down and through the ballast under-neath the tie to thereby "pump" the ballast material from a chamber, the top of which is defined by the lower surface of the tie; a means for providing a downwardly directed force on the top of the tie to displace it downwardly underneath the rails of the track system; and a means for withdrawing the tie from either end.  The scarifier means are configured to distribute a force in adjacent ballast material which contributes to the "pumping" action as the scarifier is inserted into the chamber formed beneath the lower surface of the tie to be removed.  The scarifier means may also be configured to pump ballast on their withdrawal from the chamber underneath the tie.

Abstract: ABSTRACT Foam remaining upon the surface of a liquid, more particularly a liquid used for filling into a container, for example milk, after the con-tainer has been filled is destroyed by the action of high-frequency wave-radiation.  The radiation may be infra-red, ultrasonic waves or micro-waves, and effects rapid elimination of the foam without contamination of the liquid.

Abstract: ARRANGEMENT FOR THE PREWARMING OF HEATING OIL          ABSTRACT OF THE DISCLOSURE         It is known to prewarm heating oil prior to its exit from the burner jet by means of a current energised PTC       element in heat contact with the jetstock conducting the oil to the jet.  In order to improve the prewarming efficiency and maintain the diameter of the jetstock as is, it is proposed according to the present invention to utilize at least a single     PTC      element (14) in the form of a plate which is placed within the cross-section of the jetstock, and which is in heat contact with a flat channel (16,28) into which the oil pipe is configured.  The prewarming has good efficiency and the power self-regulation of the PTC       element follows the oil temperature with little delay.

Abstract: TITLE:  A RETRACTABLE MECHANISM FOR A WRITING ELEMENT         ABSTRACT OF THE DISCLOSURE       A retractable mechanism for a writing element especially the expendable refill of a ball-point writing pen, is disclosed.  A manually depressible plunger (4) advances a latch member (7) biased to retract the plunger (4).  The latch member (7) has a pair of latch arms (11,12) one of which in an advanced or retracted position thereof engage a latch means (5,6).  Depression of the plunger (4) releases the engaged latch arm (11 or 12) from its latch means (5,6).  The resultant of the force on the plunger (4) and bias on the writing element (1) then laterally aligns the other latch arm (12 or 11) with its latch means (6 or 5). On release of the plunger (4), the bias on the writing element (1) brings a co-operating notch (16) and pivot edge (15) of the aligned latch arm (11,12) and latch means (5,6) into register for pivot action therebetween.  This pivot action and rocking of the latch member (7) about its fulcrum (9) positions the latch member rearward limb (23) in readi-ness for the next depression of the plunger (14) whereby the writing element (1) may be displaced between its retracted and projected positions (or vice versa) in response to successive depressions of the plunger (4).

Abstract: METHOD AND MECHANISM FOR INSERTING AN ELASTIC BAND IN SELECTED AREAS OF MATTRESS-WRAPPING BEDCLOTHES.             ABSTRACT OF THE DISCLOSURE.       A method and a mechanical assembly are disclos-ed for mounting, on angular areas of a mattress-envelop-ing bed sheet or similar article, segments of elastic band to elasticize said angular areas.  The method re-quires that the angular transversal seams which unite adjacent flaps of the sheet pairwise be detected by a thickness gauge ( 25, 26, 27) so as to generate a si-gnal going to a stitch counting assembly (SCA) wherein a preselected number of stitches corresponding to the angular area to be elasticized has been preselected. The sewing machine is thus started and begins to stitch the continuously fed fabric (1): meanwhile, a double fold is formed on the fabric edge (6) by a specially provided shaping device (17, FG1, FG2).  Immediately after, the elastic band feeding device (DS, 29, 30, 31, 32, 33) en-ters action and introduce the elastic band in the fabric double fold for a time determined by the Stitch Counting 2.     Assembly (SCA) and the sewing machine (11) sews the ela-stic band and the folded fabric together.  As the pre-selected number of stitches has been applied, the elastic band feeding mechanism is withdrawn, the elastic band is locally twisted and a snipping blade (34) housed in the presser foot (36) of the sewing machine (11) snips the clastic band the cycle is restarted and repeated until all the four corner areas of the bedclothes article have been elasticized.

Abstract: ABSTRACT          There is provided an apparatus for automatically peeling potatoes.  The apparatus includes a chamber which is essentially cylindrical, but which includes facet-defining walls which encroach inwardly on the space of the chamber.  There is a top to cover the chamber, and at the bottom there is a downwardly and outwardly sloping rotary member having roughened regions thereon for abrading and removing the potato skins. The provision of the facet-defining walls prevents the potatoes from rotating "en bloc", and causes them to be jostled and tumbled in such a way as to bring all parts of all potatoes into contact with the roughened abrading regions.

Abstract: ABSTRACT OF THE DISCLOSURE         A clamp for releasably clamping a rope.  The clamp comprises a support base and a plurality of independent clamping members, each having an opening therein through which the rope may pass.  The openings are substantially cylindrical in shape and disposed at an angle to a common plane of the support base.  One end of each clamping member is pivotally secured to the base.  The pivot axes of the clamping members are located at right angles to the rope and lie in a common plane spaced a predetermined distance from the openings through which the rope passes.  The said distance is less than the thickness of the rope.  The clamping members are displaceable on their pivot axis to assume an open position in which the rope passes freely through the openings, and a closed position where the rope is clamped by the members.  When the clamping members are in their open position they form an acute angle with the plane of the support base.  The passages are disposed coaxial with one another.  When the clamping members are in their open position they are in contact with each other so that the members are displaced from the open position to the clamping position while simultaneously enlarging the acute angle.
