Abstract: CONTROLLED FLOW COOLING SYSTEM FOR ENGINE HEAD FOR LOW WEIGHT RECIPROCATING ENGINE            ABSTRACT OF THE DISCLOSURE        A light metal die-cast head employs a low volume cooling system which eliminates the conventional intricate water jacket and replaces it with continuous grooves which wrap hemi-cylindrically about each combustion cylinder in a thinly spaced relation.  The grooves are exposed along their length at the deck surface of the head.  There is a critically located straight drilled passage along with two such grooves in the head, the combination of which is restricted in throat area when compared to the throat area of similar grooves in a cast iron engine block.  This results in a high velocity flow in the head and a low velocity flow in the block when they are connected in series flow relation.  The straight longitudinally drilled passage, which may include one or more of such passages, is located in the head separating the exhaust and metal valve guides; the passage has a throat area equal to or less than the throat area of either of the grooves in the head.          Heat extraction is more easily and flexibly programmed to achieve not only a more uniform wall temperature throughout the head and block, but permit a desirably slightly higher average wall temperature than conventional light metal heads for improvement in fuel economy and thermal efficiency.

Abstract: ABSTRACT OF THE DISCLOSURE           Moulding tool for making an article from vibrated concrete optimized as regards strength, the article having embedded therein a tubular sleeve located by a pin during the moulding process.  The moulding tool is designed to keep the interior of the sleeve free from concrete and to decrease wear and mechanical stress exerted on the pin during the moulding process.  Such a moulding tool is characterized in that, during the moulding process, the pin extends through a sealing and dampening body made from an elastic or semi-hard material, the sealing and dampening body having sealing engagement with the pin.  The sealing and dampening body is compressed by the sleeve so that a sealing engagement is achieved between one end of the sleeve and the sealing and dampening body and between the other end of the sleeve and a surface of the moulding tool.

Abstract: ABSTRACT              A heater for heating liquids such as water in an aquarium comprises a water-impermeable housing including a heating section for immersion in the water.  Within the heating section of the housing is a flexible, distributed planar heating element.  The housing is resistant to breakage from mechanical and operating abuse and has a high heat transfer coefficient and high heat distortion temperature. To prevent the housing from melting when a control element of the heater malfunctions, preferably the aquarium heater includes temperature limiting means such as a circuit protection element comprising a material having a positive temperature coefficient of resistance.  Preferably, the heating section of the housing is fabricated with large surface area walls to accommodate the planar heating element, and is provided with coupling means for maintainig the heating element thermally coupled to the walls of the heating section.  The coupling means can be a ribbed support for holding the heating element against the heating section walls.

Abstract: TITLE OF THE INVENTION           "MATERIAL WEB FOR THE MANUFACTURE OF FILTER RODS FOR  TOBACCO PRODUCTS AND APPARATUS AND PROCESS FOR PRODUCING SUCH WEB"                 ABSTRACT OF THE DISCLOSURE             The invention relates to a longitudinally creped paper web for use in the manufacture of filter rods.  In order to improve the filtering capacity and resistance to flow therethrough without weakening filter plugs formed from the web in respect of resistance to radial crushing the longitudinally creped web is provided with linear indentations transversely thereof which are sufficiently closely spaced one from the other longitudinally of the web to provide consistency in draw of short length sections cut from filter plugs made from the web.  The invention also relates to the process and apparatus for forming such a filter web using co-operating spaced rollers for forming controlled linear compression zones extending transversely of the web, at least one of these two rollers being provided with ribs extending at least approximately axially of the roll.  A drive to the two rollers is synchronised so that the surface speed of both the rollers is at the same speed as the speed of advance of the web being treated thereby.  The treated web may either be formed into a roll or coil for storage and subsequent use or may be fed directly to a tow machine in which it is formed at once into filter plugs in the conventional manner.          The invention also relates to filter plugs of which the filling comprises the gathered together material web.     - 1a -
