A display case being rectangular in a plan elevation, characterized by side walls and a door, each consisting of a glass panel (3,4,5,6) of equal thickness having side edges abutting at each other and having fastening means (16,17), some of them being fastened to an upper and a lower frame (1,2) respectively, the outer surfaces of the upper and lower frames (1,2) ending at a distance from the outer surfaces of the glass panels which distance is at least half of the thickness (25) of one of the glass panels, each one of the glass panels at one end abutting with its inner surface at the end face (21) of the neighboring glass panel, and at its other end (22) abutting with its end face (26) at the inner surface of the glass panel neighboring that other end, and that the fastening means (16,17) of the glass panels (3,4,5,6) are not protruding over the outer surface of their glass panel.There also is described a modular display system consisting of several such display cases.

In an electronic control device for electric ranges having a plurality of individual heat settings to selectively energize a heating element of the range under the control of a digital input to produce switching pulses having different on-off ratios, each heat setting has an associated time controlled constant power period in the start-cooking or roasting range, and in the subsequent finish-cooking range there are produced switch-on and switch-off pulses having a constant time pattern at every heat setting, while the time duration of the constant power period and the duration of the switch-on pulses in the finish-cooking range are different from one heat setting to another.

An arrangement for anchoring a mounting element in a hole of a masonry and the like with the use of binding material has a sleeve-shaped mounting element insertable in the hole and having an axis and an inner bore adapted to receive therein a threaded element, a plurality of retaining members arranged on the mounting element for fixing the latter in the hole, which retaining members extend transversely to the axis of the sleeve-shaped element and taper towards a wall of the hole, and a flange arranged at a trailing end of the mounting element so as to close a hole and having an opening for mounting a feeding device, feeding the binding material into the hole. The retaining members have throughgoing apertures through which the binding material flows so as to reliably fill the hole. The retaining members are preferably wedge-shaped. The feeding device may be inserted not only in the opening of the flange but also directly in the inner bore of the mounting element. An additional sheath may be provided for preventing escape of the binding material through a gap between the masonry and an additional structure to be mounted thereto.

A neutral bronze sheet glass has a dominant wavelength in the vicinity of 575 nm, and a monochromatic transmittance which in the range from about 400 nm to about 550 nm is on the average from about 5 to about 50% lower than in the range from about 550 nm to about 750 nm, and possesses in thicknesses suitable for glazing a luminous transmittance above 70%.
摘要:
An anchoring arrangement for securing an object to a support structure having an internal cavity includes an anchoring element which extends through an anchoring hole into the internal cavity and includes a hollow anchoring member having a passage at its leading end and a collar mounted on the trailing end of the anchoring member so as to surround the same, which supports the anchoring element in the anchoring hole and closes the anchoring hole around the anchoring member. A bag-shaped limiting member surrounds at least a portion of the anchoring element and defines a compartment therewith, and hardenable material is introduced into the compartment through the interior of the anchoring member and through the passage to fill the compartment and to harden therein in form of a body of hardened material which attaches the anchoring element to the support structure and prevents an extraction thereof from the anchoring hole. The limiting member may be air-permeable but impermeable to the hardenable material to allow for venting of air present in the compartment, and may be of an elastically, preferably non-isotropically, yieldable material. A shielding element is used for guiding the hardenable material toward the passage and for protecting the interior of the anchoring member from contact with the hardenable material. A valve arrangement may be provided which prevents backflow of the hardenable material from the compartment into the interior of the anchoring member upon the termination of the introduction of the hardenable material into the compartment.
摘要:
An anchoring member is inserted into an anchoring hole in a support structure and has transverse dimensions smaller than those of the anchoring hole, and is supported with clearance in such anchoring hole by means of a cap member of ring-shaped configuration which surrounds the anchoring member at the trailing end thereof and closes the open end of the clearance. The anchoring member is of a tubular configuration and is closed at its leading end, an aperture communicating the interior of the anchoring member with the clearance. A body of hardenable material is introduced into the clearance through the aperture and by means of a shielding arrangement accommodated in the interior of the tubular anchoring member and communicating with the aperture. At least a portion of the ring-shaped cap member is at least translucent so that the introduction of the hardenable material into the clearance can be monitored therethrough. A depression, preferably an annular groove, is visible through the translucent portion and has such dimensions that, due to its viscosity, the hardenable material will not be able to penetrate into the depression until after the pressure in the clearance has exceeded a value indicative of the completion of the clearance-filling process. A small-sized opening communicates the clearance with the exterior of the cap member and allows air to escape from the clearance during the clearance-filling operation, while preventing the hardenable material from escaping therethrough until the pressure of the hardenable material has reached a predetermined level.
