Title: Tyre pressure control valve III
Inventor: KARTHAEUSER KLAUS DIPL ING
IPC: G05D16/06
Filed: 1987-09-02
Abstract: A tyre pressure control valve for a tyre pressure control device in motor vehicles is proposed whose switching function is insensitive to high centrifugal forces such as occur at the wheel rim at high wheel speeds. The control valve has a seat valve (22) with valve seat (19) fixed to the housing and a valve element (21) which interacts therewith and is attached to a control piston (23) with control faces (29, 30), lying opposite one another, for pressure to act. The control piston (23) is secured to two diaphragm springs (38, 39) which are arranged at an axial distance from one another and are each clamped in the valve housing (10) at their outer edge. By means of this constructional mounting, the bearing friction of the control piston (23) is virtually negligible as a result of which the control valve becomes insensitive to centrifugal forces. <IMAGE>

Title: Ultrasonic imaging device
Inventor: BARTELT HARTMUT DR
IPC: G01S7/52
Filed: 1987-12-21
Abstract: In ultrasonic imaging devices which operate in accordance with the pulse/echo method, time-delayed transmitted signals which result in artefacts in the ultrasonic image are generated by reflection of the echo signals at ultrasonic transducers (2 and 2'). According to the invention, echo signals are received in pairs from various directions in a temporally sequential fashion from an object (4) under investigation. Said signals are superimposed in a weighted manner in order to generate a location-dependent object function on which the pictorial representation is based. Artefact components in the echo signal can be largely suppressed by the weighted superimposition of the echo signals. Ultrasonic tomography. <IMAGE>

Title: Pressing box for pressing goods of all kinds
IPC: B30B9/30
Filed: 1988-05-02
Abstract: A pressing box which is filled with material which is pressed into the box at a high pressure is conventionally rectangular in cross-section and its walls are provided with reinforcing ribs on their outsides. In addition to the walls of the pressing box, the said reinforcing ribs must also be constructed very solidly, which means that the box has a very large overall weight. According to the invention, the rectangular inside box has an outside casing which encloses it on all sides and is supported by the reinforcing ribs, which are now supporting elements, on the inside box. The pressing forces are now evenly distributed over the entire circumference of the casing, which is now preferably circular in cross-section, and also where the said pressing forces are converted into tensile forces. This means that the pressing box can now be lighter in weight. <IMAGE>

Title: Apparatus for the laying of filamentary material
Inventor: WEICHELT HELLFRIED
IPC: B65H54/28
Filed: 1988-09-23
Abstract: The invention relates to an apparatus for generating the to-and-fro movement during the laying of filamentary material and is used for the winding of bobbin bodies of differing size. The aim of the invention is an apparatus having a long service life which can be operated at a low outlay in terms of time and servicing. The object on which the invention is based is to provide a laying apparatus which is characterised by a low wear of the constructional elements and which allows an exact setting of the reversal points during continuous operation and with a differing bobbin size. The object is achieved, according to the invention, in that, on the friction-wheel principle, between a pair of fixedly connected rods consisting of two rods and guided in rollers, a take-up roller set in rotation is pressed alternately against the rods over a very short switching travel, with the result that the to-and-fro movement is generated. During the change-over operation for a change of direction, the disengaged state of the take-up roller is bridged by a positive retention of the pair of rods.

Title: Synchronised three-membered telescopic rail for draw-out members
IPC: A47B88/49
Filed: 1988-10-25
Abstract: The present invention relates to a synchronised, three-membered telescopic rail for draw-out members, in particular for full extension or overextension, having a body rail (1) which is fixedly attached to a receptacle for the draw-out member, a draw-out member rail (2) which is fixed to the draw-out member, and an intermediate rail (3), a synchronising roller (8) mounted on the intermediate rail bearing against the first and the second rail on rolling surfaces (5, 6) arranged opposite one another and rolling on these surfaces as the draw-out member is pushed in or drawn out. In order to ensure reliable synchronisation even in the case of full extension or overextension, in the case of which the synchronising roller loses contact with at least one of the rolling surfaces, it is proposed according to the invention that there be provided a locking device (7, 18) which, as the draw-out member is drawn out, secures the intermediate rail (3) against further relative movement with respect to the body rail or the draw-out member rail (1 or 2), as soon as the synchronising roller loses contact with one of the rolling surfaces (5, 6), and which, as the draw-out member is pushed in, is substantially precisely released by the remaining rail or by a part connected thereto when the distance of the roller axis (13) to the points of the body rail and of the draw-out member rail, lying at the height of the roller axis in the fully pushed-in state, is the same. <IMAGE>
Patent DE-3837074-A1 (DE)
Title: Heater for vehicles and the like
Inventor: KENNER ERICH
IPC: F23D11/44
Filed: 1988-10-31
Abstract: In stationary-mode heaters, operated with liquid fuel, for motor vehicles, whose combustion chamber is fitted out as a vaporiser burner, hitherto a glow plug with an open glow filament has usually been used. The voltage dependence of such a glow plug is disadvantageous for operation, in particular when starting. It has also been found that increasing carbon deposition occurs over time. According to the invention, vaporisation of the liquid fuel takes place with the exclusion of air using a sheathed-element glow plug. Ignition can take place independently of voltage with the aid of a spark plug (high-voltage electrode). In one embodiment, the vaporiser is designed as a heat exchanger tube in which the sheathed-element glow plug is arranged. <IMAGE>
