A knotting arrangement, especially for spool frames for warping and other textile machines in which the orbital knotting head is connected to a suction tube and has a freely movable clamping body, e.g. a ball, therein which, when air pressure is supplied to the suction tube can press the ball against a seat to hold the yarn end. The clamping body is not connected to any elements within the head an...

Splicing head operated by a compressed gas for use in an automatic splicing device for producing by splicing a thread connection without knots, having a splicing head with at least two openings to admit the compressed gas, which accepts the two threads which are to be joined together, and has the capability to effect the mutual tangling, interwining, mixing and/or winding around of the fibers of t...

There is disclosed a speed control apparatus installed in an automobile equipped with an automatic transmission. This apparatus includes a microcomputer, an input interface circuit, an output interface circuit, an actuator for the automatic transmission, and an actuator for maintaining the speed of the automobile at the speed set by the driver.

A gem holder for fixedly holding a plurality of gemstones 2 during notching by means of a laser comprises a plurality of relatively flat strips 14, each having a plurality of datum notches 18 cut across at least one of its longitudinal edges, and a base plate 10, at least the upper surface of which is provided with at least one set of substantially parallel slots in which the strips are insertable...

In order to improve the sensitivity and the spectral resolution in measuring the luminescence of diverse sample materials, adapted optical imaging relationships at variable excitation output are provided for the different optical paths of the luminescence light emitted by the sample material. An excitation bundle of rays which can be stopped down and the central beam of the secondary beam which em...

Addition of H and a radical I' (R<1> = org. carbon radical; R<2> = H, R<1>; R<3> = C1-C4-alkyl) onto olefinically or acetylenically unsaturated compounds II (Y = H or together a further bond; n = 0 or 1; A, B = -CO-O-; -O-CO-; -CRR-O-; -CR-NR-; R = H, C1-C4-alkyl, identical or different; R<4>, R<5> = H, org. radical; A + B (n = 1) or A + B (n = 0) can be linked to give a 5- or 6-me...

A coating 2 that can be applied to a structure (1) to indicate damage to the structure that is otherwise not generally visible, includes a plurality of dye-loaded opaque capsules (3) which are designed to rupture when the structure is subject to a pressure greater than that liable to damage the structure. When ruptured, the capsules 3 release the dye which is readily visible. A fluorescent dye is ...

An apparatus for optical monitoring of the surface of rod-shaped smoking articles and/or filter rods for the tobacco industry comprises a conveying means transporting the rods perpendicularly to their longitudinal direction and a high-pressure lamp which serves as light source and which is connected via an optical fibre cable to a sensor block; the optical fibre cable is divided amongst at least t...

In the general Formula I R1 stands for hydrogen, halogen, trifluoromethyl, trifluoromethoxy or cyano; R2 represents hydrogen, halogen or methyl; R3 is C1-4 alkyl; and the R3 substituents may be the sa...

A hydraulic cement mix including hydraulic cement, aggregate, sufficient water to effect hydraulic setting of the cement, and an additive comprising mixtures of alkali and alkanolamine salts of alkylarylsulfonic acids and alpha olefinsulfonic acids, and alkali and alkanolamine salts of fatty acids, and a nonionic component selected from polyethylene glycol derivatives and diethanolamine adducts of...

A combined brake cylinder/air reservoir device in which a relatively small, tubular-shaped piston in a positioning chamber is connected to a larger power piston having an application chamber on one side and a release chamber on the other side in which air is stored in place of separate reservoirs. A replaceable cylinder liner is provided to receive different-sized power pistons. During a brake app...

A hydraulically controlled brake is equipped with a device preventing an excessive rise in temperature of the hydraulic fluid. The control piston of the brake comprises a cup-shaped piece and also an insulating core accommodated in the cup and having a free end face via which the piston pushes on the friction element. The core is screwed onto a central threaded column projecting from the bottom of...

Relative angular movement between two linear members is detected by shining light from a light source (11) through a triangular mask (12) in one member onto a mirror (10) in the other member and reflecting the image of the triangular mask onto a linear array of detectors (15). Movement between the two members causes different detectors in the array to be illuminated and the position and number of ...
