Abstract: The invention relates to a device for feeding a stream of hot gas to a printed circuit board during convection soldering in a soldering installation. The feed device comprises a nozzle plate (1) having at least one drilled hole (3), which opens into a hot gas nozzle (2) arranged on the nozzle plate (1) and having a nozzle opening (4). The invention is defined in that the hot gas nozzle is formed by a flexible helical spring (2). The invention permits the nozzle plate with the hot gas nozzles to be advanced right up to the printed circuit board under all peripheral conditions which occur. In particular, the printed circuit board can, for instance, be advanced right up to the nozzle plate even when a central support for the printed circuit boards or some other disruptive contour is present.

Abstract: A conveyor device for printed circuit boards includes a carrier that continuously circulates between conveyor wheels. At least one carrier element supporting placement of the printed circuit board and at least one resilient clamping element clamping the printed circuit board on the carrier element are arranged on the carrier. A switching device moves the clamping element back and forth between an open position of the clamping element, in which the printed circuit board can be loosely placed onto the carrier element, and a spring-loaded closed position of the clamping element, in which the printed circuit board can be pressed onto the carrier element by the clamping element.

Abstract: A process for producing an inner sole including a sole base and a plurality of blisters integrally formed on the sole base and extending away from the sole base, the process comprising the steps of preparing a mold with a recess for forming the sole base and the blisters, the recess having a number of projections on a first area and clearances for forming hollow spaces on an opposite second area, preparing a flexible elastic material, introducing material into the mold to form the sole base with integral blisters, and removing the inner sole from the mold.

Abstract: The present invention relates to methods for determining the relative immunogenicity of exogenous antibody variants comprising a) creating a non-human animal, which is transgenic for a standard antibody, b) contacting said transgenic non-human animal with an exogenous antibody whereby said exogenous antibody is a variant of said transgenic standard antibody of a), and c) determining the immune response of the transgenic non-human animal elicited by the exogenous antibody of (b).

Abstract: The invention relates to an item of footwear, particularly an item of sports footwear, e.g. ski boot, cross-country ski boot, hiking footwear or the like. The leg (5) of the item of footwear is made of a textile material and is joined, preferably adhered, to a preformed, for example, extruded toe cap (4), to a, for example, extruded counter (6), and to an anatomically shaped midsole (2), above all when a watertight item of footwear is desired.

Abstract: In a drive system for tandem axles a prime mover (1) drives a reduction gear (2) in the housing (4) of which one differential (6), service brakes (7) and planetary gears (8) are situated. The output of the reduction gear (2) is connected, via universal shafts, in an easy manner with the drive train of the tandem housing (3). It is thus possible to situate the tandem housing (3) in the vehicle chassis (10).

Abstract: A proposed machine tool has one hydrostatic drive system, one lower chassis where one motor for driving the wheels and one upper chassis is provided which is pivotably disposed upon the lower chassis and comprises one pump for supplying the drive system with pressurized medium, wherein a rotating passage is situated between upper and lower chassis and, in the lower chassis, one or more electronic components are provided as lower-chassis electronic system and serve to control and/or regulate the components of the lower chassis.

Abstract: The invention relates to an inner or inlay sole (2) for a shoe, in particular a sports shoe, which permits optimal damping properties and optimal wearing comfort. The above inner sole (2) is constructed in an integral manner from a flexible material and comprises blisters (6). According to a preferred embodiment, the blisters (6) are hollow in form in order to meet the requirement particularly well. According to a further embodiment, perforations (20) are provided in the region between the blisters and/or in the blisters themselves, for the optimisation of the damping properties and for removing fluids from the foot of the user. A combination of the two embodiments is particularly advantageous.
