Abstract: ABSTRACT OF THE DISCLOSURE           In a vacuum-moulding process for manufacturing an electrical heating unit, in which process a resistance heating coil is placed on a sieve-like tray, above a suction box, and a slip is applied thereto, this slip being composed of ceramic fibres, so that a ceramic fibre layer builds up under the action of suction, it is proposed, according to the invention, that portions of the sieve-tray be closed, in regions beneath the resistance heating coil, in particular by means of spacing strips, and that these strips, which cover some of the perforations in the sieve-tray, be placed beneath the resistance-heating coil, but in a manner such that the impervious regions of the sieve-tray are narrower than the width dimensions of the heating coil.  These measures lead to the result that the space inside the heating coil remains free of fibre material during the vacuum-moulding operation, so that the temperature difference between the radiating side of the heating coils and their rear side, which lies within the composition forming the fibre block, is smaller than in conventional heating units of this type, in which there is a risk of crystallization of the fibres forming the fibre block.  The use of spacing strips produces retaining webs on the radiating side of the fibre block, these webs ensuring that the heating coils are securely anchored.

Abstract: Abstract A desired decorative design on packaging such as tubes is made up of a combination of printed matter and a decorative foil such as a metal, pigmented or textured pattern foil. The method involves the steps of first applying the printed matter to the material with an ink treated to prevent adherence of the foil to the printed matter. Thereafter, the foil coated with an adhesive  is  positioned  against  the  material  and heat and/or pressure applied so that a foil transfer will occur onto all areas of the material engaged by the foil that are devoid of the printed matter.  The  foil  is applied with a smooth continuous silicone  pad.  Exact  registration  is  assured  and  the use  of complicated die designs is wholly avoided.

Abstract: METHOD OF PROCESSING MARGARINE OR BUTTER        FOR SQUEEZE PACKET CONTAINERS              Abstract of the Disclosure Margarine or other foodstuff with similar physical properties is warmed to room temperature and placed in a mixing bowl (10).  The margarine is blended by stirring with paddles (12).  Then, the margarine is mixed until it has a substantially uniform viscosity by a recirculating pump (14), extrusion of the margarine from the recirculating pump through a screen (16), and continued stirring with the paddles.  A 15 to 30 second burst of steam is applied into jacket (20) liquifying but not clarifying the margarine contiguous with the edge of the vessel.  The recirculating pump draws the liquified margarine from the edge of the mixing howl and pumps it into the top center of the margarine where is it blended into substantially unheated margarine.  The process is repeated until the margarine attains a viscosity in the range of 16,000 to 18,000 centipoise.          Once this viscosity range is reached, the margarine is pumped into a holding tank (26).  A filling machine (30) draws the margarine from the holding tank and pumps metered volumes into heat sealed squeeze packets (60).

Abstract: ABSTRACT A method of removing paraffin build up from an oil well which includes determining the location of a cooler portion of the oil well at which paraffin build up occurs, introducing an inductance heating element down into the annular space between the oil well tubing and the oil well casing, positioning the inductance heating element in the vicinity of the cooler portion and inductance heating the inside surface of the oil well tube to at least the temperature about that of the melting point of paraffin.  Preferably, the inside surface of the tube is heated on the down stroke of the oil well sucker rod and at the start of the sucker rod up stroke in order to strip the paraffin from the tubing. The outside surface of the sucker rod is heated on its up stroke and the inductance heater has multiple bands of coil to heat the same general area of the sucker rod as it travels.

Abstract: 1.                      STACKER-RECLAIMER     ABSTRACT OF THE DISCLOSURE     A stacker-reclaimer has a luffing and slewing mounting supporting a boom structure with a main, forwardly extending boom having material-conveying means running along it, and a rearwardly extending tail boom with a counterbalance weight depending from its rear end.          The tail boom is at a higher level than the main boom, to provide clearance for a feeder conveyor to the material-conveying means.  The counterbalance weight is attached by a pivot on the tail boom, and is displaceable about the pivot by a control cable attached to a non-luffing part of the luffing and slewing mounting forwards of the luffing axis whereby the weight is displaced forwards in relation to the pivot in upward luffing movements of the boom structure.  This compensates for the rearward displacement of the rear end of the tail boom in such movements, and reduces the maximum overturning moment to be resisted in the working luffing range.

Abstract: Abstract of the Disclosure An apparatus for drilling a large profile workpiece has a support fixable relative to the workpiece, a drill arbor centered on an axis intersecting the workpiece, a bit coaxially carried on the arbor, and a drive connected to the arbor for advancing the bit toward the workpiece either at a relatively fast advance speed or at a relatively slow boring speed.  A guide element displaceable in the support parallel to the axis is secured by a compression spring to the arbor for joint movement parallel to the axis with a predetermined limited lost-motion stroke, in other words, the arbor and element can only move relative to each other through this stroke.  A switch carried on the element and a switch operator carried on the arbor control axial movement of the arbor along with an abutment carried on the element and a stop on the support engageable with the abutment that define an outer position for the guide element and arbor.  Thus the guide element is prevented by engagement of the abutment of the stop from moving further away from the workpiece than the outer position.  A clamping device is provided on the support for arresting the guide element thereon, to that, when the guide element is prevented by engagement of the abutment on the stop from moving further away from the workpiece than the outer position.  A clamping device is provided on the support for arresting the guide element thereon, to that, when the guide element is arrested on the support, the axial stroke of the arbor is determined by the switch and the operator in dependence on the lost-motion stroke.
