Abstract: As a process for storing wafer blocks within a production line in which liquid wafer batter is baked to form wafer sheets which are cooled and coated on one side with an edible coating composition, preferably together with cover sheets, are joined to one another to form wafer blocks filled with coating composition, which wafer blocks are cooled on passing through a wafer block cooling apparatus, it is proposed that the wafer blocks which have already been cooled in the wafer block cooling apparatus, during a predetermined storage time, together with the newly delivered wafer blocks which are still to be cooled, are conducted through the wafer block cooling apparatus at least a further time, the wafer block transport density in the wafer block cooling apparatus being multiplied during the storage time, and that, after the storage time, the transport of the wafer blocks away from the wafer block cooling apparatus is increased above the extent corresponding to the delivery of new wafer blocks which are still to be cooled until the wafer block transport density within the wafer block cooling apparatus has fallen again to the extent corresponding to the delivery, whereupon the transport of the wafer blocks away from the wafer block cooling apparatus is decreased again to the extent corresponding to the delivery.

IPC: E02D13/10
Filed: 1989-04-11
Abstract: In a method for driving of a pile (2), where the pile has a top side and side faces extending substantially perpendicularly to the top side, a hammer assembly is held firmly in position in relation to the longitudinal axis of the pile and drives the pile into the ground by hammering on the top of the pile. According to the invention the hammering action is exerted within a defined area of the pile top, not extending to the edges of the pile, while the edge zones are held free of the hammering action. This may be carried out by means of a ram head (110) for fixation of the hammer assembly in relation to the pile, said ram head having a bottom part provided for transmitting the impact impulse to an intermediate plate or impact piece (100) which, in turn, transmits the impulse to the pile top, said bottom part of the ram head being provided with a projecting collar (126) embracing the impact piece to hold it within a defined area not extending to the edges of the pile top.

Inventor: BAILEY ALAN CURTIS
IPC: C03B37/025
Filed: 1981-07-03
Abstract: A method of making solid glass articles by the flame hydrolysis technique. A thin stratum of low viscosity glass soot is applied to the surface of a mandrel. First and second coatings of glass soot are deposited on the surface of the thin stratum to form a porous preform. The refractive index of the soot particles of the first coating is greater than that of the soot of the second coating, and the soot of the first coating has a viscosity lower than that of the second coating. The mandrel is removed, and the soot preform is subjected to a high temperature whereby it is consolidated to form a dense glass blank. The glass surface tension and the relative viscosities of the inner and outer portions of the preform cause the aperture to close during the consolidation process. The thin stratum, which preferably includes P2O5, smoothes over the damage caused by removing the mandrel and reduces or even eliminates seed formation at the axis of the resultant glass blank. The blank may be heated and drawn into a filament, or it may be sliced into optical windows, lenses or the like.

Title: Corner holder for mirrors or similar objects
Inventor: NIELSEN POUL ERIK
IPC: A47G1/16
Filed: 1985-12-16
Granted: 1990-09-28
Abstract: A corner holding for mirrors and similar elements includes a base element and a plurality of holding members, with the base element being adapted, by breaking along the weakening lines formed by a cross-shaped recess, to be divided into four sections, and with a shape corresponding to the shape of the holding members being provided with locking pins for the introduction into locking holes of the base element of the sections which are furthermore provided with fixing holes. The base element includes a circular plastic plate adapted for division into four sections defined by the cross-shaped recess, while the holding member includes an outwardly open pocket adapted for reception of a mirror corner so that a mirror by way of four holding members can be fixed to base elements secured to a wall surface. With the holder, a considerable simplification is realized by the mounting of a given mirrors wall since the number of base elements and holding member always corresponds to the number of mirrors. The mounting of the mirrors, for example, requires the use of a base element divided into four sections together with four holding members, while the mounting of four mirrors for a mirror wall requires the use of one entire base element, four half base elements, and four quarter base elements, that is, in total, four entire base elements and sixteen holding members.

Abstract: The components of the coupling for pressure lines are a female coupling (1) and a male coupling (2). The female coupling (1) has two adjacent axial bores (3; 4) of different diameters. An annular groove (5) around the smaller bore (4) is formed coaxially with the bores (3; 4) from the larger bore (3) side. When the coupling components (1; 2) are fitted together, the male coupling (2) is inserted into the bore (3) of the female coupling (1). Here, the male coupling (2) is pushed over the nipple (6) formed by the annular groove (5) and the smaller bore (4). The seal fitted in the male coupling (2) sealingly engages the smooth outer surface (7) of the nipple (6). The shape of the female coupling (1) and the mating male coupling (2) makes coupling and uncoupling with a predetermined flow cross section possible with less force than with prior art couplings.
