Patent DE-3316082-A1 (DE)
Inventor: AFFA ALFRED ING GRAD
IPC: G01B21/02
Filed: 1983-05-03
Abstract: A measuring system for measuring the relative position of two machine parts of a processing machine includes a scale fastened at one end by means of screws to the slide of the machine. The other end of the scale is joined by means of an adhesive layer with one end of an expansion element. The other end of the expansion element is fastened in a similar manner by means of screws to the slide. For the compensation of thermally induced length changes of the scale, the expansion element is provided with a coefficient of thermal expansion substantially greater than that of the slide piece. Thermal expansion of the expansion element is dimensioned in such a way that the measuring length of the scale is preserved in an unaltered length in the event of temperature fluctuations by means of increased compressive forces applied by the expansion element to the scale.
Patent DE-3317861-A1 (DE)
Title: Heat exchanger
Inventor: KUEMMEL JOACHIM DIPL ING
IPC: B22C5/08
Filed: 1983-05-17
Abstract: Heat exchanger consisting of a housing (1) having built-in heating surfaces (3) for cooling bulk materials (8) - in particular hot foundry sands - has a damming system in the form of a sand cascade, and consisting of an upper perforated plate (9) having many small individual holes (11) and a lower perforated plate (10) having a small number of individual holes (12), which are separated by perforated plates (4, 15), it being possible for the passage of sand through the slide system (5, 6, 14) to be regulated or valved off. The passage holes can have a triangular, elongated or T-shaped hole in order to be able to run such a damming radiator in a wide control range. The perforated distance plates (4) form, moreover, a statically highly loadable support plate for accommodating the substantial weights of bulk material. The holes (15) of the distance plates (4) permit the dammed material to flow and float in the cascade chambers, and thus ensure the passage of bulk material uniformly through the upper cascade plate holes (11) in all loading cases. <IMAGE>

Title: Process for producing printed circuit boards having contact fingers with gold-plated edges
Inventor: MERKENSCHLAGER HANS-HERMANN DI
IPC: H05K3/06
Filed: 1983-05-27
Abstract: In existing processes, the gold plating of the edges of contact fingers on printed circuit boards is very cost-intensive. In the case of the invention, this is avoided as a result of the fact that the printed circuit boards are coated with an etch-resistant photographic foil, and exposed, developed, etched and stripped using a pressure tool containing contact fingers and conductor pattern. Then the stop-off mask is applied while leaving the contact fingers and solder lands exposed. The contact fingers are then masked with adhesive tape and the printed circuit boards are provided with liquid resist and dried. The adhesive tape is then peeled off, the contact fingers are gold-plated and the liquid resist is stripped. The contact fingers are then masked with solder stop-off resist, and the solder lands are activated, hot-tinned and washed. The solder stop-off resist is peeled off the contact fingers and the printed circuit boards are then processed further mechanically.

Title: Loading truck with a conveying and cutting device
Inventor: MENZL HERBERT ING
IPC: A01D90/04
Filed: 1983-06-23
Abstract: In a loading truck with two cutting devices, of which at least one knife row projects from the front wall of the conveying channel into the conveying channel and at least one knife row passes through the conveying channel from the rear wall of the conveying channel, the knives of the second cutting device located in front in the conveying direction are equipped with a knife guard, by which foreign bodies can pass into the space between these and the knives of the first cutting device. The knives of the first cutting device are equipped with a foreign-body guard which triggers the stopping of the conveying device by the cut-off of a change-speed gear. The knives of the first cutting device can be extractable from the conveying channel, especially if foreign bodies should pass into the loading space. Otherwise, after the second cutting device has been swung out, the foreign body is removed from the conveying channel by changing the conveying device over to reverse. The change-speed gear is designed as a chain transmission with backgear. The cutting devices can be made remotely controllable by actuating means. The removal of a foreign body can be made largely automatic by means of a control and regulating unit.

Title: Method and circuit arrangements for digital SECAM standard identification, and simultaneous synchronisation of the line-frequency switch
Inventor: SCHMELOVSKY KARL-HEINZ PROF DR
IPC: H04N9/64
Filed: 1984-09-03
Abstract: The object of the method is to obtain a reliable decision using predominantly digital means as to whether the received signal is modulated in accordance with the SECAM standard, and to derive a control signal therefrom for the colour killer. In addition, a control signal is intended to be formed for synchronisation of the line-frequency switch. For this purpose, the frequency of the colour subcarrier is converted at the start of the line of the SECAM signal into a digital variable and this is then added over the part of the field located outside the vertical blanking interval with a mathematical sign which alternates line by line and is controlled by the line switch. A test is carried out towards the end of the field to determine whether the result is greater in magnitude terms than a predetermined threshold value. A positive test result indicates that the SECAM standard is present. At the same time, a test is carried out to determine whether the result is positive, a negative test result indicating that the line-frequency switch is synchronised incorrectly, whereupon a correction is carried out. <IMAGE>

Title: Hydraulic control device for the load-moment limit in a jib crane
Inventor: HOEFER FRIEDRICH-WILHELM
IPC: B66C23/90
Filed: 1984-09-08
Abstract: A hydraulic control device (10) for the load-moment limit on the jib arm (11) of a loading crane is proposed in which the directional control valve (35) serving to control a telescopic cylinder (17) has a load-holding non-return valve (55) which at the same time serves as a shut-off means for the pressure-medium flow increasing the load moment. A control chamber (59) is allocated to the spring-loaded closing member (57) of the non-return valve (55). The control chamber (59) is relieved via a control line (61) for the return flow (48, 33) and, when the load-moment limit responds, can be acted upon by a pressure control valve (66) with feed pressure in such a way that the pressure-balanced closing member (57) shuts off the pressure-medium flow increasing the load moment. To unlock the non-return valve (55), its control chamber (59) is relieved by the spool (64) of the directional control valve (35) via a control passage (62), as a result of which a movement at the telescopic cylinder (17) reducing the load moment can be controlled despite response of the load-moment limit. <IMAGE>

Title: Coupling for heavy-current cables
Inventor: NEUMANN HERBERT
IPC: H01R13/622
Filed: 1984-11-16
Abstract: The coupling for heavy-current cables for the electrical and mechanical connection of conductor ends of two heavy-current cables which are to be connected consists of two bolts (2, 3) each of which is to be connected to one conductor end and whose ends (4, 5) which point in opposite directions in the coupled state are constructed as contact pieces (6, 7) which can be pressed towards one another. The ends (4, 5) can also have such contact elements (6, 7). The end of the one bolt (2) is provided with a coupling sleeve (8) which cannot be pulled off over the end (4) of the same and, in the coupled state, engages by means of its open end (9) over the end of the other bolt (3). The open end (9) of the coupling sleeve (8) has a first closure part (14), which is constructed as a screw sleeve, a closure lever or, in particular, as a bayonet closure part, and which can be moved to produce a closure effect with a second closure part (15) which is provided on the end (5) of the other bolt (3). Finally, at least one closure part (14 and/or 15) and/or its support (8 and/or 16) can be displaced longitudinally with respect to the bolts (2, 3) in the coupled state, so that the bolt (2 and/or 3) allocated to it can be pressed against the other bolt (3 or 2 respectively) with a compression-element arrangement (17) being prestressed (Fig. 2). <IMAGE>

Patent DE-3443269-A1 (DE)
Title: Wall element
Inventor: HAERTLING FRANZ DIPL ING
IPC: E04B1/84
Filed: 1984-11-27
Abstract: The invention relates to a wall element (1), the length of which is a multiple of the width, and which, being set up with its length running vertically, can be assembled with other identical wall elements to form a solid wall such as, for example, a sound-insulating wall, a screen wall or the like. The novelty of the invention is a connecting and clamping device (4 to 9) which is arranged in the interior of the wall element and by means of which the wall element can be bolted to neighbouring wall elements without the transverse load-bearing elements, which are otherwise required in the case of wall elements which are set up with their length running vertically, being necessary. This novel interior bolting arrangement permits not only a rapid and simple construction, but, likewise, an uncomplicated re-construction without the individual wall elements being damaged in any way. A further advantage is the possibility of setting up a solid wall, using wall elements according to the invention, on an uneven ground surface without having to erect a substructure or other types of foundations beforehand. <IMAGE>
