Abstract: PCT No. PCT/CH85/00001 Sec. 371 Date Sep. 9, 1985 Sec. 102(e) Date Sep. 9, 1985 PCT Filed Jan. 10, 1985 PCT Pub. No. WO85/03030 PCT Pub. Date Jul. 18, 1985.The invention is primarily concerned with a sandwich material (55) made of sheets based on paper. This material is substantially comprised of a sheet (42) of corrugated paper (44) forming one or several layers. An intermediate paper sheet (31) is bonded to the corrugations of the sheet 42. A film (29) of a thermoplastic compound adheres physically as the result of an extrusion to the outer side of the intermediate paper sheet (31). The process for manufacturing this material consists firstly in extruding a film (29) of thermoplastic compound on the intermediate paper sheet (31), and then in bonding the web (27) of protective layer thus obtained on the corrugations of the sheet of corrugated paper (42). The invention is remarkable in that these operations are carried out on a standard machine for manufacturing corrugated paperboard. However, on the one hand an adhesive setting instantly at room temperature is used, and on the other hand the various heating elements used to bring about the setting of adhesives polymerizing through an endothermic reaction are kept switched off. The invention is particularly useful for making furniture or wall panels.

Granted: 1989-11-30
Abstract: In a process for recovering sulphur from a typically relatively concentrated gaseous stream of hydrogen sulphide, the stream is reacted with pure oxygen or oxygen-enriched air in a furnace 2 to form a gas mixture including hydrogen sulphide and sulphur dioxide. The hydrogen sulphide and sulphur dioxide then react to form sulphur vapour and water vapour. The temperature of the gases in the furnace 2 is controlled by introducing into the gases a quenchant. The quenchant is preferably liquid water although other liquid quenchants may be employed. Alternatively a vaporous quenchant stream comprising at least 80% by volume of steam is employed. The process enables relatively high rates of formation of sulphur vapour to be achieved for a given furnace volume.

Each of the electrodes (48) includes an end portion on the corresponding end of the body (14) in electrical contact with the corresponding lead (16, 18) of the discrete electronic device (10) and a contact portion (66-72) extending along the mounting surface (36-42) for making electrical connection to a circuit having a portion defined on a surface to which the device (10) is mountable. The discrete electronic device (12) is manufactured, prior to encapsulation, by known and proven techniques. Preferably the body (14) is a rectangular solid with each of the four sided having electrode contact portions (66-72) thereon to thus serve as one of four possible mounting surfaces each (36-42) with substantial mechanical stability. When the discrete electronic device is an inductor, interruption of the magnetic field is minimized by spacing the ends of the inductor core from the ends of the encapsulating body, separating the electrode contact portions, having the area of the electrode end portion less than the area of the end of the encapsulating body, and having the cross-sectional area of the most narrow section of the electrode end portion no less than the cross sectional area of the magnetic wire of the inductor winding. In the case of a shielded inductor, phenolic core inductor or non-inductive device such as a resistor, capacitor or diode, solid metal electrode can be employed.

Abstract: 1. Disk player with a magazine 2.1. A known compact-disk player with a magazine consisting of several superimposed compartments for accommodating compact disks has a system of levers and a pulley driven by an electric motor in each compartment for removing a disk from the compartment. 2.2. To decrease the considerable expense for each compartment (2) in the magazine (11), there is an access opening (15) on the rear wall of each compartment, through which a plunger (4) can travel to thrust the compact disk (7) out of the compartment. The plunger can be a flexible shaft that extends forward from the rear wall of the magazine through a tubular guide (3) and along one side of the magazine. The plunger can be introduced into and extracted from the compartment by means of a toothed rack (14) secured to the front of the flexible plunger (4) in conjunction with the cogwheel (10) that is driven by an electric motor (6) and engages the rack. 2.3. When embodied in a compact-disk player the invention is especially appropriate for installation in a motor vehicle. 2.3. Figures 1 and 2.
