Patent DE-3728945-A1 (DE)
Title: Changes in the basic structure of plotters, in this case primarily flat plotters
Inventor: HEINEMANN THEO
IPC: B43L5/02
Filed: 1987-08-29
Abstract: Basic structure of plotters, primarily flat-bed plotters. The basic structure according to the invention makes it possible to move the drawing paper in both axial directions relative to the drawing plane. In this arrangement, the paper which is not used during the individual, intermittent plotting operations is normally retained in two chambers. The paper is pushed with accuracy of register between a plurality of plotting operations of partial regions of the overall drawing, so that overall drawings can be produced in a size which is limited only by the size of the paper itself, even on plotters with relatively little axial movement. All that is previously known is the offsetting of a plotter frame over the paper stretched on a plane separate from the plotter and the winding of a paper stock, as a result of which a plurality of drawings which are self-contained per se can be plotted in succession. The basic structure according to the invention permits the relative movement of the paper, being the lighter medium, not only in the winding direction but also transversely thereto. Even with only one chamber, the movement takes place transversely to the winding direction. In this case, however, a reversal of the paper and a mirror-imaging of the partial regions to be plotted subsequently are necessary. Moreover, only a doubling of the axial length of the plotter in the winding direction can thus be achieved.

Patent DE-3742402-A1 (DE)
Title: Method and device for inert-gas welding
Inventor: LANGENBAHN HANS WILLI DR ING
IPC: B23K9/09
Filed: 1987-12-15
Abstract: The invention relates to a method for inert-gas welding using a metal-wire electrode which is tracked. This is periodically supplied with electrical welding energy from an energy source. Five welding parameters, and namely in particular the wire advance speed, the basic current or the basic voltage, the pulse current or the pulse voltage, the basic time as well as the pulse time can be predefined. The harmonisation of these welding parameters was in the past very difficult and was subject to the subjective process evaluation of the operating personnel. In order to avoid these difficulties and in order to control and to define the nature of the material transfer, a mathematical determination of the process parameters with quality preselection is proposed. The dependence of the pulse energy on the overall energy per period for the respective welding wire/protective gas combination is calculated. After predefining the weld seam form, the desired welding speed as well as the desired welding result, the pulse current or the pulse voltage, the basic current or the basic voltage, the pulse time, the basic time as well as the wire advance speed are determined. <IMAGE>
Patent DE-3743715-A1 (DE)
Title: Gear case
Inventor: MUEHLBERGER UWE
IPC: F16H57/028
Filed: 1987-12-23
Abstract: The invention relates to a machine case, especially a gear case for receiving gearwheels or any other vibration-exciting elements. To suppress the radiation of sound over the case surface, provision is made for dividing this into zones of small area. For this purpose, the case wall is stepped in an imbricated manner into narrower and wider regions in a plane preferably perpendicular to the gear axis. Furthermore, the case-wall thickness is made different in the individual step regions. This makes it possible to detune the vibrations of the outer surface, so that, as a result of deliberate asymmetry, the case does not constitute a diaphragm-like vibrational structure.

Title: Folding pram and pushchair
Inventor: KLAUBE HANS-JOACHIM
IPC: B62B7/08
Filed: 1987-12-29
Abstract: The invention relates to foldable prams, pushchairs and dolls' prams. The vehicle comprises front-axle struts, rear-axle struts, a seat with a hinged footbox and hinged backrest, a slide and armrests, the slide being arranged on the footbox side on the rear-axle strut via a hinge part known per se, and a backrest side part being hinged to the seat and an adjusting bar for the footbox being hinged to the armrest. The arrangement of the slide on the footbox side allows the pram to be used and folded from this position. The arrangement according to the invention of the subassemblies means that it is no longer necessary to swivel the slide onto the side of the backrest in order to initiate the folding process. Hinging the adjusting bar of the footbox to the armrest and the side part of the backrest to the seat ensures the forcible change in position or adoption of the folded position of the footbox or the backrest (Fig. 1). <IMAGE>

Title: Mounting for a rail laid in a channel in a track-supporting slab
Inventor: RADLER ERICH
IPC: E01B9/30
Filed: 1988-08-03
Abstract: Known mountings for rails laid in a channel in a track-supporting slab are not suitable for current working operations, require an undesired wide design of the rail channel and thus make considerable demands on mounting. It is now proposed ... the rail (21) laid in the rail channel (12) with respect to the track-supporting slab (11) by means of insertion pins (41) which are to be fitted into receptacles (123) starting from the side walls (122, 122') of the rail channel (12) , which pins, at the end facing away from the insertion end (411), merge into an excentric (412) which in the set condition comes to bear, with prestress, against the rail foot (211, 211'). The novel mounting is not only easy to assemble, but it also proves capable of meeting the current demands made of such a mounting, and furthermore it is possible to make do with a rail channel which is only slightly wider than the foot of the rail. <IMAGE>

IPC: F24C15/20
Filed: 1988-10-10
Abstract: For rooms with excess heat, in particular large-scale kitchens, known devices for aerating and deaerating are two bulky, so that it is not possible to accommodate them above an extractor hood. Various components, such as fan, the heat exchanger and other parts, are fixedly installed and can be reached only with difficulty for cleaning purposes. The new device is to be constructed, as a unit with fixed overall dimensions, compactly and with such a flatness that it can be installed without any problems above an extractor hood. Provided in a housing which is substantially smooth on the outside and is adapted in its overall dimensions to the space conditions existing above extractor hoods, in particular in large-scale kitchens, is a flat heat exchanger, below which a flat bypass duct runs. The heat exchanger and the bypass duct are separated from one another in their central region by means of a plate. The heat exchanger is removably mounted in the housing. A bottom panel of the bypass duct is designed as a fat and condensate trough. The device can be installed above the space remaining above extractor hoods or even combined with an extractor hood to form a structural unit. <IMAGE>

Title: High-temperature heating element and method for its production
Inventor: GRUENWALD WERNER DR DIPL PHYS
IPC: C04B35/581
Filed: 1989-01-20
Abstract: The invention relates to a high-temperature heating element having a substrate of aluminium nitride and, applied thereon, a heating conductor, and a method for producing said heating element. High-temperature heating elements are used in the motor vehicle industry for producing ceramic heating devices, in particular for producing spark plugs and glow attachments (heater attachments). The disadvantage when using aluminium nitride ceramic for producing high-temperature heating elements is that due to the good thermal conductivity of aluminium nitride by heat dissipation a strongly increased heating power is necessary to keep the heater at a predetermined temperature. To reduce heat dissipation, the heating element according to the invention has a substrate (1) of aluminium nitride, in which the substrate region (1a) which is to insulate thermally is doped with foreign ions. The heating conductor (2) can consist of one of the conventional heating conductors used in known high-temperature heating elements. A substrate (4) can serve as protection against oxidisation. A high-temperature heating element according to the invention is shown for example in Fig. 1. <IMAGE>
