Abstract: The exchanger makes use methodically of the high convective power of metal wires in a gas current. At least two webs (7, 8), which are specially prepared and adapted for each case of exchange, made of metal with a high thermal conductivity, are welded on either side of a grid of metal tubes (9, 10) presenting to them a flat (11, 12) for welding. The set of tubes (9, 10) which are mounted in parallel between these webs constitutes a unitary panel (2, 3, 4). The assembly of one or more unitary panels (2, 3, 4) by links adapted to the ends of the tubes (9, 10) forms a metal wire exchanger (1) between a gas passing through the webs (7, 8) and a fluid circulating within the tubes (9, 10). In particular, a series of vertical exchangers (1) are disposed in a star configuration below and around a sheath (30), in which one or more fans (31) create the reduced pressure required for the passage of the air through the webs (9, 10). <IMAGE>

Abstract: In known diode split transformers, transient effects occur during the forward line trace which impair the image quality. In the novel diode split transformer, no transient effects impairing the image quality should occur. Essentially, this is achieved by the fact that a diode (D4) is connected in parallel with the part-winding (I1) of the diode split transformer which is closest to earth, in such a manner that interference oscillations occurring at the part winding closest to earth during the forward line trace are bypassed to earth. <IMAGE>

Abstract: A rectangular container is made up from a base (11), a cover (12) parallel thereto, two mutually parallel faces (13, 14) and two mutually parallel sides (15, 16). The sides and faces are pivotably secured to the base via pivots parallel to the base so that the container may be collapsed into flat form when being transported empty. To simplify collapsing the container, at least the sides (15, 16) are sub-divided into sections (150, 154; 160, 164) which are hinged together. When the container is collapsed, the side sections (150, 154; 160, 164) are folded together about at least a second axis before they are lowered onto the base.

Abstract: The invention relates to an undercarriage for a funfair railway vehicle. An undercarriage of this kind has wheel shoes (11, 17) mounted in articulated fashion on in each case one end plate (6) to ensure that the wheels (25) rotatably mounted in the wheel shoes (11, 17) can be set against the rail (1) in articulated fashion from several sides. In order to improve the running quality of the wheels (25) because of the particularly large centrifugal forces arising at high speeds, the invention envisages mounting the individual end plate (6) flexibly on the vehicle frame (3, 4) via a ball-and-socket joint (5) and supporting it, likewise flexibly and in articulated fashion, relative to the vehicle frame (3) via a connecting rod (7). The advantage is thereby achieved that, due to the flexible bearings, all the forces acting on the wheels (25) can be taken up and dissipated with little noise and with a high damping effect.

Abstract: N-(2,2,6,6-tetraalkyl-4-piperidinyl)amic acid hydrazides contain a light stabilizing group, a heat stabilizing group and an amic acid hydrazide functionality in the same molecule. The amic acid hydrazide functionality in the compounds enhances the photooxidative stabilizing properties of the hindered amine groups and contributes thermal and oxidative stabilizing and metal complexing properties to the compounds. The novel compounds are excellent light stabilizers for polyolefins, have low volatility and are not readily lost from polymeric systems via volatilization, migration or extraction.

Abstract: The invention relates to a food processor comprising a housing 1, a bowl 3, a cover 4 having a feeding tube 5, a driving shaft 6 which is driven by a motor  via  a transmission mechanism 7, the said driving shaft being formed by an upper shaft 11 and a lower shaft 12 which are connected together by means of a coupling 19, the upper shaft 11 being journalled in the cover 4 and being suitable for connecting a tool thereto, the lower shaft 12 being journalled in a frame plate 15 by means of a bearing 17, said frame plate being suspended in the housing. The value of the tolerance of clearance S depends on a large number of other tolerance-dependent dimensions. In known food processors the axial forces are compensated by the bearing 17. According to the invention the driving shaft 6 is journalled axially in the housing 1 (bearing 25). As a result of this the tolerance path for the clearance S has become much smaller. It is also possible to journal the upper driving shaft 11 axially in the bowl 3.
