Abstract: Drainage catheter (1) such as a nephrostomy catheter and method for the manufacture thereof, comprising the extrusion from flexible plastic of a tubular basic body (2) with a central channel (8), the attachment to one end of said basic body of a coupling element (3), the deformation of the opposite end part (4) into a curved form and the arrangement in the curved end part of a number of side-openings (5) connecting said central channel to the outside. Said basic body is extruded such that said central channel comes to lie eccentrically in said basic body. During the plastic deformation of said end part said basic body is supported for free rotation along its lengthwise axis and the arranging of the side openings is carried out after said end part has been plastically deformed into the curved shape.

Inventor: JOHANSSON SVEN ARNE
IPC: E04F15/20
Filed: 1990-05-10
Abstract: A floor assembly (10) providing a floating floor structure to minimise noise generation and/or propagation, comprises a primary or lower floor (18) on which a secondary or upper and floating floor (12) is mounted by means of isolation means (16) inserted between the floors. The isolation means (16) comprises zones (20) of an open cell foamed flexible ploymeric material. The zones (20) are spaced apart by free zones (22) in which the floating floor is unsupported. In contrast to the standard approach to acoustic insulation and lowering of frequencies at which resonance occurs by increasing the mass of material present, this provision of free or unsupported zones (22) of the floating floor nevertheless lowers the resonance frequency and improves performance while reducing consumption of materials.

Abstract: The present invention relates to an agricultural machine comprising at least one group of working members (19) and a structure (14), to which said group (19) is connected by means of a suspension device (22). The latter is structured in such a way that the group of working members (19) can: 
 
  - shift upwards and downwards in relation to the structure (14) as a result of the deformation of the deformable quadrilateral formed by the suspension members (48, 52) with said structure (14) and the group of working members (19); 
  - pivot about the straight line (72) 
 
<??>In contrast, because of the lateral suspension members (60, 66), the group of working members (19) cannot pivot about the straight line (75). In the invention, it is also possible to ensure the pivoting of the group of working members (19) about the straight line (74) is prevented or at least limited.

Date Jun. 28, 1990.Prereduced iron oxides are supplied to a smelting vessel (1) for the production of iron or steel by directing a hot reducing offgas from the vessel (1) into a vertical riser duct (8) without substantial cooling of the offgas and by way of inlet (16), particulate iron oxide containing material is entrained in the hot reducing offgas as the gas is conveyed upwardly through the duct (8). The hot gas heats the entrained material to a temperature at which partial reduction of the iron oxide occurs, the hot gas thereby, losing sensible heat. Additional materials may be introduced to the duct (8) for entrainment in the gas. Particulate material is separated in a cyclone (9) from the gas and the separated partially reduced material is introduced to the smelting vessel by way of passage (12). The particulate material, or part of it may be recycled by way of passage (15) through the vertical rise duct before the partially reduced material is introduced to the smelting vessel and only part of the hot reducing offgas emitted by the vessel may be directed into the duct.

Title: Apparatus for processing glass.
Inventor: HERRINGTON RICHARD A
IPC: C03B29/08
Filed: 1990-05-18
Abstract: An apparatus for processing glass sheets includes a furnace and a bending station traversed by a conveyor for carrying the glass sheets. A plurality of heaters mounted in the furnace each heat associated areas of the glass sheets in accordance with setpoint temperature signals representing desired values of temperatures for heating associated areas of the glass sheets. One or more parameters of the glass sheets, such as thickness and color, are sensed and the setpoint signal values are changed accordingly. The parameter values are also utilized to change the spacing between the upper and lower mold members in the bending station to adjust the bending pressure applied to the glass sheets. Furthermore, the parameters are utilized to change the speed of the conveyor sections in order to vary the time that the glass sheets are in the furnace and thus the amount of heat imparted to the glass sheets.
