Abstract: The sewing machine to stitch ribbons to the edges of fabrics, and especially half sections of sliding clasp fasteners, has a carrier arm for the sewing machine (10) as the lateral carrier (2b) of a fixed gantry (2) across the fabric support table (1). The fabric laying surface (1a) extends as far as the side of the gateway away from the sewing point The sewing machine, for stitching half sections of sliding clasp fasteners to fabric edges, has a straight sewing head (11) and a fabric advance at the presser foot. An additional fabric transport unit for the fabrics is at least at the zone of the straight sewing head. A cut-out in the fabric support table is at the zone of the straight sewing head and the fabric transport mechanism, as an access for the operative. The fabric transport system has two continuous paths (3a,3b), parallel to the stitching direction, with a limit guide (4) between them for the edges of the fabrics. Feeds (5,5') for covering ribbons (6) flank the limit guide, for the cut edges of the fabrics, and for the half-sections of the sliding clasp fastener. The sections of the sliding clasp fastener are delivered in cut lengths, or they are drawn off a wound roll. The straight sewing head and the looper head form a multi-needle sewing machine.

Abstract: A hearing aid includes a shaped body that is adapted to an individual auditory canal. A casting cavity is created from a central casting space element, an outer casting space element, and a canal element. The casting cavity is filled while inside the auditory canal. The central casting space element, which remains on the hearing aid, has an outer and an inner ring as well as a tubular and extendible membrane. The outer casting space element delimits the casting cavity on the outer face. After casting, the outer casting space element is replaced by an electronics module including a loudspeaker. The at least partly flexible canal element can hold the loudspeaker canal open, can be joined in a fixed or detachable manner to the outer casting space element, and can essentially close the opening of the inner ring and can limit the axial mobility of the inner ring.

Abstract: The invention relates to surfaces with hydrophilic properties and a method for producing such surfaces. Surfaces are provided with hydrophilic properties by applying a coating containing hydrophilic silicic acid by means of the inventive method. Said surfaces can be textile or polymer surfaces, metallic or wooden surfaces. The silicic acid can be permanently connected to the polymer surface or be in the form of a non-fixed coating. The inventive hydrophilic silicic acid is applied in a very simple manner by applying a suspension containing silicic acid particles in a solvent on the corresponding surface, whereupon the solvent is removed or the silicic acid particles are fixed to the surface by means of a carrier. Condensing devices of dehumidifiers, foams or sponges are examples of surfaces that can be provided with the inventive hydrophilic surfaces.

Abstract: With this group control, the cages of a group of lifts can be selected for embarking passengers in such a way that the embarking passengers arrive at the shaft door of the selected lift before the selected cage, thus reducing unnecessarily long stops. For this purpose, every lift is provided with a memory (15), in which the times required by a passenger on a floor to move from respective actuated call registering and display devices to the shaft doors of the lifts are stored. A comparator (16) connected to the memory (15) compares the time allocated to the actuated call registering and display device with the time required by the cage to move to the call input floor. If the travelling time is less than the time required by the passenger to reach the shaft door concerned, a switching device (17) connected to the output of the comparator (16) becomes active in such a way that the lift concerned is excluded from the call allocation method.

Abstract: 1. Low-pressure steam condenser system for condensing the steam leakage from shaft seals (2) of a steam turbine installation (1) having heat exchanger surfaces (77) cooled by the condensate of the condenser (60) of the steam turbine installation (1), the low-pressure steam condenser (70) being integrated into the condensate induction line (77) of the condenser (60). This system allows the low-pressure steam condenser (70) to be designed as a pressure-free heat exchanger. Particularly advantageous is an arrangement of said heat exchanger inside the condensate collecting space (61) underneath the condensate level (63) in the condenser (60). In this arrangement, the low-pressure steam condenser (70) can form an extension of the condensate induction line (75) within which there are arranged heat exchanger pipes (77), around which the condensate can flow, in which the low-pressure steam condenses. It is advantageous for the condensate to flow in on both sides of the low-pressure steam condenser (70) from which the condensate enters approximately in the centre into the condensate induction line (77). The arrangement is particularly space-saving and cost-effective because of the pressure-free design of the low-pressure steam condenser. <IMAGE>

Abstract: The invention concerns a vehicle-parking system with a number of vehicle pallets (4) which can be moved on a planar network of mutually perpendicular tracks (8, 9). Each pallet has its own drive unit (17) which is supplied with electric power through power pick-ups (25, 26) which make contact with current-carrying rails (23, 24) running along the tracks (8, 9). So that information concerning the lateral and longitudinal displacement of the pallets (4), and the corresponding drive programme, can be transmitted without the need for special signal lines to the pallets (4), the invention proposes that each pallet (4) is fitted with at least two separate pairs of power pick-ups (25, 26). A fixed selection unit displaces the current-carrying rails (23, 24) and the power pick-ups (25, 26) relative to each other in such a way that each of the two pairs of pick-ups (25, 26) only makes contact with either the rails (23) running in one direction or those (24) running in the direction at right angles. The two p airs of pick-ups (25, 26) are connected to a discriminator circuit (22) which activates various drive programmes, depending which pair of pick-ups (25, 26) is picking up power.
