Apparatus for feeding and transporting blanks of corrugated paperboard and the like is disclosed wherein a stack of blanks is received on a blank feeding station having a first belt-over-roller conveyor which cooperates with an angularly inclined control gate of a gate assembly to feed blanks from the bottom of the stack beneath the control gate and effect shingling of the blanks, whereafter the b...

In this comminution device, elongated rotor blades (15) which interact with stationary blades (11) are attached in each case to rotor discs (7) arranged with axial spacing from one another. Each rotor blade (15) has a leading cutting edge (5) which moves on a circular rotation path (9), and an outer surface (23) which extends in the direction of the chord with respect to the rotation path (9) betw...

An expandible tire-building drum for making toric shaped tire carcasses built in the form of cylindrical sleeves is provided. The cylindrical sleeves have at their extremities, annular bulges which are circumferentially inextensible and are radially developed towards the inside. These bulges form the beads on the carcass. The height of the bead is one-half the difference between the internal diame...

A solenoid device includes a cylindrical armature movable within a core tube the tube and armature being formed from magnetisable material. The armature is smaller in diameter than the interior diameter of the tube and a pair of axially spaced recesses are defined between the tube and the armature, each recess accommodating a circumferentially extending cylindrical member. The members serve to loc...

When an empty molding box arrives at the molding machine on a roller track extending through the machine, it is placed on a pattern plate carrier with a pattern situated thereon and is lowered thereon on to a transverse roller track on which it is transferred, by means of a thrust drive operating on the carrier, to the empty station of a two-station transporting carriage on which it is then moved,...

A spectrophotometer includes a wide band radiant energy source and a detector for providing an output signal proportional to the intensity of the radiant energy received thereby. A light pipe system is divided into a reference path and a sample path. Such system coacts with a rotary assembly having a variable monochromatic filter located diametrically opposite to an opening through which radiant e...

In a methanol production process comprising synthesis gas generation, catalytic synthesis, recovery of crude methanol and purification by distillation, organic compounds of higher boiling point than methanol (the so-called "fusel oil" stream) are contacted in liquid form with a gaseous stream to be fed to synthesis gas generation, whereby to convert those compounds to synthesis gas. When an alkali...

A ski binding wherein the housing of a safety device is secured directly to the upper side of the ski or to a cross country frame whose front end portion is pivoted to the ski. The housing has and/or contains friction reducing balls, rollers, liners and/or edge portions which guide a carriage for the front or rear hold-down device. The carriage is movable relative to the housing in a horizontal pl...

A sun protection consisting of at least two frame-type supporting beams. The beams are formed of respectively one cross beam and two lateral beams adapted to be put together, with mounting ears. These ears are provided at the bottom ends of the lateral beams which ears are seated on respectively one bolt of a clamp holder provided with a clamping element.

A process and apparatus are provided for making a bead wire and bead zone filler for a vehicle tire. The apparatus has a rotatable drum and deformable tubular member disposed on the drum. The external surface of the tubular member is adapted to receive a strip of elastomeric material to be shaped into the bead zone filler. The tubular member is changed from tubular to annular shape with a fluid un...

A method of producing electrical conductor cable having a polyethylene-based coating, wherein additive material such as a filler is first mixed with a vehicle including an ethylene propylene rubber to provide a homogeneous concentrate, and the concentrate is then blended with polyethylene to constitute a coating composition for application to a cable as by extrusion. The concentrate-polyethylene b...

A gas discharge display device comprising a gas-filled, -gas-tight enclosure, an insulating matrix member dividing the housing into two chambers and comprising an insulating plate having a plurality of apertures therethrough, arranged in an array of rows and columns corresponding in number to a desired number of image points, a cathode electrode disposed in one chamber and extending parallel with ...

In this process for producing and subsequently increasing the heat resistance of a phenolic resin moulding with a metal covering which surrounds the phenolic resin moulding, the production takes place by an injection moulding process, the metal covering being inserted into the mould before the injection moulding, whilst the increase in the heat resistance is carried out by a heat treatment. The ai...
