Abstract: Abstract of the Disclosure An installation for casting from ceramic material in slip form tanks each having side walls, a bottom wall and an open top, the installation comprising a plurality of moulds arranged in a generally horizontal line on a support structure, each mould consisting of a female part having a cavity for shaping the external surfaces of the side walls and bottom wall of a tank to be cast and a male part having a core which is adapted to be located in the cavity of the female part for shaping the internal surfaces of the side walls and bottom wall of the tank, and means for clamping the moulds each in a closed condition for casting, the mould parts being carried by transport means enabling them to be moved along the support structure in a direction longitudinally of the line of moulds for separating and closing the mould parts, the mould parts being arranged on the transport means so that the tanks are each cast in a position in which the open top faces in a direction generally parallel to the longitudinal direction of the line of moulds.     The present novel installation avoids problems associated with conventional casting of cistern tanks in having to use very strong clamps to hold the core precisely in place and involving manual lifting of the core out of the female part of the mould.

Abstract: ABSTRACT OF THE DISCLOSURE       A microwave oven with an electrically conductive surface such as a flat metal plate positioned parallel to the bottom of the oven cavity and spaced therefrom by approximately one tenth the wavelength in free space .lambda.a of the excitation microwave energy.  The width of the plate is an odd multiple of a quarter wavelength (.lambda.a/4) and the depth is an even multiple of .lambda.a/4.  Preferably the plate is spaced an odd multiple of .lambda.a/4 from the feed aperture at the top of the oven cavity.  The edges of the plate are spaced from the vertical side walls of the oven cavity, at least in that region of the cavity where the microwave energy level would be greatest in the absence of the plate.

Abstract: ABSTRACT             KEYLESS CHUCK CONSTRUCTION             A chuck construction for use in association with a power tool or the like.  The construction is particularly adaptable for use as a keyless chuck and comprises a base suitable for attachment to the driven shaft of the tool and a collar threadably received by the base.  Jaw means are adapted to receive a work piece such as a drill bit, and rota-tion of the collar relative to the base operates to drive the jaw means into gripping engagement with the work piece.  A truncated cone is interposed between the collar and jaw means, and a thrust washer is interposed between the base and jaw means.  The structure permits the utilization of plastic for the collar and base.  Other parts including the jaws, the force-applying cone, and the thrust washer are produced of hard metal, and these members are arranged so that the hard metal jaws and other hard parts do not damage the plastic. The thrust washer can be attached by means of an oppositely threaded fastener or other suitable means whereby the con-struction can be utilized in both forward and reverse opera-tion of the tool.

Abstract: ABSTRACT OF THE DISCLOSURE           The testing method comprises subjecting the welds to a mechanical test using a pneumatic hammer and during the test the so-called "stuck" welds are destroyed.  The remaining welds then undergo a punctiform inspection, using a rheometric method.  This method consists of creating a potential difference between the supply electrodes,  of which there are even numbers in contact with the weld.          Measuring electrodes located in the vicinity of the supply electrodes make it possible to obtain a resulting quantity of the different voltages measured.  After calibrating the resulting value of the voltages makes it possible to deduce therefrom the diameter of the weld and consequently its efficiency.

Abstract: Abstract The present invention provides a machine and method wherein envelopes are removed from a supply hopper, one by one, and then transmitted to a plurality of sequen-tially disposed cutting stations wherein one end edge of the envelope is first severed, and thereafter an adja-cent side edge of the envelope is severed.  The envelope with two adjacent edges thus severed is transmitted to a processing station at which the envelope is opened and held open by suction cups, for removal of contents by an operator.  The envelope is thereafter transmitted to a detector station to confirm content removal and then to a recovery station, and then to a point of discharge. Means is provided for adjusting the opening of the suc-tion cups at the processing station, and stop means is provided for positioning the envelope as it reaches the processing station.  The envelope is transmitted toward the processing station in horizontal disposition, and in one form of the invention at the processing station it is repositioned into angular disposition prior to the gripping action of the suction cups.

Abstract: ABSTRACT OF THE DISCLOSURE           According to the invention, during the welding of the buffer layer, the axis of the welding electrode runs at an angle with respect to the plane of the abutting surfaces of the components, and the sides of the melted down weld beads of the buffer layer overlap.  This alters the course of the solidification front and produces a different alignment of crystals or grains, as compared with conventional welding in which the axis of the electrode is usually approximately at right angles with respect to the plane of the abutting  surfaces.          The axis of the electrode preferably runs at an angle with reference to two reference planes which are at right angles to each other and passing through the axis of the component, one of the said reference planes passing through the weld point.          Thus the tracking angle in relation to the reference plane passing through the weld point may be between 15 and 35°, while the other tracking angle may be between 15 and 50°.
