A lacquer coating is applied to a laminated metal composite forming a sliding element such as a plane bearing and has particles of solid lubricants incorporated therein to form islets of greater thicknesses than the surrounding film and which serve as lubricant-trapping surface formations. The particles may be of polytetrafluoroethylene, fluorinated graphite or molybdenum disulfide and the lacquer...

A residual lap clearing apparatus for clearing a residual lap from a lap bobbin. The residual lap clearing apparatus comprises a rotary brush roller (11) for stripping the residual lap off the lap bobbin, a support roller (13) for supporting a lap package for residual lap clearing operation, a brake mechanism (21) for braking the lap package during the residual lap clearing operation, and a comb r...

The invention deals with improvements in doffing of yarn packages and insertion of bobbins (either conical or cylindrical) into the cradle mechanisms of operating stations of a yarn handling machine including definition of the insertion path, retention of the bobbin relative to the operating station while axiilary operations such as formation of a thread reserve are performed, and control of the i...

A method of monitoring yarn quality in a yarn texturing process comprises measuring the velocity of the travelling yarn at two locations and comparing the measured velocities. At a first location the yarn tension is sufficient to draw out the crimp and at a second location the tension is lower such that the crimp is developed. Apparatus for performing this method comprises a measuring device (28) ...

An on-line method of inspecting an apertured mask sheet (10) to be formed into a shadow mask for a colour cathode ray tube is disclosed. In one of several embodiments described the mask sheet (10) is linearly scanned by a laser spot (32) transverse to the direction of advancement (30) of the mask sheet. The peak values of the grey levels of the laser light transmitted by the mask sheet are detecte...

A cleaning compsn. concentrate, for mixing with water, contains (a) 40-60% of citrus terpenes, e.g. limonene or dipentene, (b) 10-20% of diethyl phthalate, (c) 10-20% of alpha-and/or beta-terpiniols, (d) 5-10% of emulsifier, (e) 5-10% of tuja oil, and (f) 3% of lemon oil and dipropylene glycol. The concentrate is mixed with water, pref. by means of a water jet pump, to give a compsn. contg. 90-99%...

The disposable, triangular or trapezoid napkin (1) has a narrow, conical holder-part (2) the surface (3) of which continually widens out towards the cover-part (4). Alternatively, the serviette is bottle-shaped with straight or curved side edges (5, 6). Part of one end of the cover part can be torn off along a perforated line. The free end of the covering part is turned over to form a pocket the t...

A yarn splicer employs aero-dynamic forces through air channels in an outer block serving sections in the inner yarn channel, which splay the yarn ends, then opposing tangential twist is applied above and below the splay, which joins the ends together. The inner block (4) has a yarn entry slot (3) into the tubular splicing channel (2). Connected to this channel are two slots with air entry at (12...

To splice slubbing, sliver, roving or yarns, they are twisted together and after bonding, are twisted back against the direction of splicing rotation. Pref. the spliced material is twisted back pneumatically. Before splicing, the ends to be joined are twisted open pneumatically, and any part not needed for the splice is blown clear at the same time as the ends are twisted open. ADVANTAGE - Method...

The device is intended for the accumulator production of traction batteries of clad positive plate (PANTZER) type. It guarantees that the battery remains sealed, while the connection between the lid and the pole terminal remain movable. Through a plastic body (1) and a screw of a cable lug (3), a cup-shaped sealing body (5), the device is connected to the polar terminal (9). In its bottom side, th...

Esterified epoxide-extended polyols (EEEPs) of the formula P(OH)a+c(EPO)n(FE)b where P is a polyol having a = 2-8 primary hydroxyls, c = 0-8 secondary and tertiary hydroxyls, a + c is in the range of 3-8, EPO is a C3-C6 epoxide, FE is a fatty acid acyl moiety, n is the minimum epoxylation index average number having a value generally equal to or greater than a and is a number sufficient that great...

The present invention relates to high-frequency generator for cutting tissue having adjustment devices, with which at least one of the momentary electric output values, such as e.g., current, voltage, power or electric arc can be set. The present invention is distinguished by, for improvement of the initial incision behavior, an electronic desired-value transmitter and a measurement device having ...
