A motor vehicle has a vehicle body (21;31) to which is secured a corrosion protection device (10;20;) comprising a sacrificial anode made of a less noble material than the vehicle body, whereby in use, an electrolytic cell is created between the sacrificial anode (10;30), the body (21;31;) and moisture in electrical contact with both the sacrificial anode and the body, so that the sacrificial anod...

A universal winding consisting of a plurality of successive figure-8s spaced radially around a mandrel with the figure-8s being spaced such that the crossovers exist in all but one location to form a payout hole extending from the exterior of the winding into the interior of the axial opening therein in which the speed of the traverse or speed of the mandrel is varied with respect to one another i...

A system for controlling an electro-magnetic clutch for automobiles has a stepwise increase of the clutch torque for reducing the engaging shock. The system comprises a gate circuit for producing a signal by signal by shift lever clutch operation, a monostable multivibrator for producing a clutch engaging period signal by the output signal of the gate circuit for a predetermined clutch engaging pe...

The invention relates to a regulating arrangement in particular on packing machines for the feed of weblike packing material in register with decorations or folding indications, so-called crease lines, present on the web. In accordance with the invention the desired control is obtained by regulating the tension of the web with the help of a guide roller over which the web is passed. The speed of t...

1. Process covering hollow bodies such as glass bottles with a porous protective coating, the process being of the type in which immersion in a bath of liquid is carried out by plunging into a vinyl plastisol the hollow body which is previously heated to a temperature sufficient to cause formation of a gel of vinyl resin at its surface, followed by heating of the hollow body thus covered, the proc...

PURPOSE:To enable judgement on the propriety of an input circuit at all times by providing a buffer circuit for detection of abnormality different in the logic threshold besides an input buffer circuit. CONSTITUTION:Judgement is made on whether an input signal is 1 or 0 between logic thresholds Vth4 and Vth5 through an input buffer circuit 2 with the logic threshold Vth2, where Vth4>Vth2>Vth5. On ...

A pleated media filter element is disclosed which includes pleat spacers which are an integral structural part of the pleated media. The construction of the pleat spacers is accomplished by scoring on the unfolded media a continuous line pattern upon the portion of the media which, when folded, forms a pleat tip of the element. When the scored media is folded into pleats the patterns each define a...

A vehicle guidance and control system has a number of trucks (2, 3) whose movement is controlled by a base station (4). Each truck periodically fixes its own position in relation to marker boards (8) consisting of patterns of reflective coded stripes by scanning a narrow laser beam (14) in a predetermined direction across the stripes. Using at least two boards its position can be determined by tri...

To reduce costs both through material and labour savings of a nuclear plantheat exchanger, the latter comprises two quadrangular cross-section headers (1, 2) coupled by a yoke-like tube nest (3) which is cold pre-deformed in such a way as to minimize the primary stresses of thermal origin developed during the operation of the exchanger.

A helical scanning type video tape recorder includes a rotary cylinder which is slidable on a video tape; and a pair of vertical magnetization recording heads mounted on the peripheral wall of the rotary cylinder at prescribed positions. The plane of the vertical magnetization recording heads which faces the magnetic plane of the video tape is provided with a main magnetic pole and auxiliary magne...

2- and/or 6-pyridylethylamino-substituted fluorans useful as color formers, particularly in pressure-sensitive carbonless duplicating systems and thermal-responsive marking systems are prepared by the interaction of (pyridylethylaminophenyl)carbonylbenzoic acids with 4-hydroxy- or alkoxyanilines or by the interaction of (disubstituted aminophenyl)carbonylbenzoic acids with N-pyridylethyl-4-hydroxy...

The coded data (12) on the record carrier (10) and the method for encoding such data (12) in tracks (14) provide a relatively simple and yet very effective means for making the data record carrier (10), and particularly the data (12) recorded thereon, highly tolerant of errors such as "burst errors" where one or more spots of data on the data record carrier (10) are obliterated. The data (12) are ...
