Abstract: ABSTRACT   The disclosed apparatus is used for splicing the laps of two reels of web material delivered to a processing machine, the splicing occurring in two different modes.  The device comprises a pressure arm (28) and an accele-ration arm (29), both mounted so that they can be shifted angularly around a common pivot point (48).  The pressure arm (28) is made of two levers (53, 54) on which a pressure roller (19) located between two short levers (79, 80), and a cutting device (66) bearing the knives (71, 72), are arranged.  The acceleration arm (29) is made of two side levers (88, 89) supporting the axle (96) of an acceleration roller (25).  The arms (94, 95) can be shifted angularly by means of a pneumatic cylinder (108) and the acceleration roller (25) is then positioned in such a way that it allows crossing the pressure arm (28) with the acceleration arm (29), when the mode of splicing changes.  The device is used in a machine processing web material, for instance a printing cutting press, and allows, using the same elements, "IN" lap splicing or "OUT" lap splicing.

Abstract: APPARATUS AND METHOD FOR REMOVING RECUPERATIVE CONDENSATE      Abstract of the Disclosure A furnace having a recuperative heat exchanger including apparatus for draining condensate and then flushing the exchanger with water to remove residual condensate.  The recuperative heat exchanger lowers the temperature of the products of combustion from approximately 500°F to approxi-mately 100°F thereby recovering sensible heat and heat of condensation before exhaust into the flue.  Preferably, the recuperative heat exchanger functions as a preheater for forced air which is then directed past a second heat exchanger adapted to receive a circulating fluid which is heated by the combustion burner.

Abstract: ABSTRACT            The processes of the invention comprise depositing onto a foamable or non-foamable support, in a first selected area or zone, a coating or print containing at least one radiation initiator for polymerization and, in a second selected area or zone which can optionally partially encompass the first zone, a coating based on a cross-linkable monomer; providing a pre-gelling treatment and, at least locally, a mechanical graining treatment; providing also a polymerisation of the covering of the first zone by radiation initiation so as to fix its appearance and thereafter a gelling treatment which, by causing fluidisation of the second zone material, causes the disappearance of the grained appearance in the cross-linkable monomer and may also cause an expansion.  The processes are particularly applicable to the production of wall coverings and floor coverings.

Abstract: HEAT EXCHANGER            ABSTRACT OF THE DISCLOSURE          A heat exchange apparatus includes a core mounted within a casing and two fans arranged to draw air from the exterior of a building through the core in a first path and to draw air from the interior of the building through the core in a second path.  The core is made up from a plurality of tubular cells each formed from a single folded sheet of aluminum and having a slot shaped cross section.  The short sides of the slot are arranged to face the inlet of cold exterior air so that it impinges upon the outer surface of the short side.  The fan drawing the warm air is arranged to direct air onto the other surface of the short side so that the short side and the surrounding portions of the long sides act as an effective heat exchange sur-face free from the seam of the tubular core which is arranged adjacent opposite the short side.  A differen-tially perforated baffle plate spreads the cold air over core such that more cold air is directed to the warm end of the core.  The amount of warm air passing through the core is arranged to be greater than the amount of cold air so as to maintain the core above frosting tem-peratures.  The excess of air can be arranged by by-passing air to and from the interior of the building through openings in the casing.

The grab head on one arm (3), preferably the lower arm, is subdivided vertically into a lower U-shaped member (35) fixedly connected to the arm (3) via a housing (11) and an upper U-shaped member (18) rotatable relative to the lower member (35) and provided with locking means (28,29,30) for retaining the pipe, drill collar or the like.  The two members (18, 35) are provided with rotation means intended to bring the upper, rotatable member (18) from an arbitrary angular position into a locked position in which its claw aperture (20) is in alignment with the claw aperture (36) of the lower member (35).  The rotation means which brings the two apertures (20 and 36) into alignment, in a preferred embodiment, consists of the facing surfaces on the two members (18, 35), which are formed as complementary, helical, inclined planes (32,37) whose ends (entry and exit of the helix) are connected via respective surfaces (33 and 38 respectively) which form an acute angle relative to the centerline of the housing (11).

Abstract: ABSTRACT     The invention relates to a method of producing a container of plastic material capable of being oriented and/or crystallized, in which a substantially tubular blank is, in at least two mutually con-secutive and mutually separate shaping phases or shaping stages, re-shaped into the container. The blank is reshaped into the container in that mechanical forming elements (34,42) stretch the material in the axial direction of the blank, and in the circumferential direc-tion of the blank. By stretching the material in each separate shap-ing stage to a regulated degree, there will be accumulated in the ma-terial a total stretching corresponding to the requisite stretching in order to impart to the material the desired and predetermined ori-entation and thereby the requisite strength properties.
