A spring (24) fits between the plunger (15) and base (26) of the brake cylinder (9). The cylinder base (9) is reinforced by a spring plate (25), and a brake release spindle (30) passes through the plate (25). The base (26) has an inward-opening passage (27) for the thread (28) which engages the brake release spindle (30). The spring plate has an inner annular protrusion (31) which centres the spri...

Nonextruded concentrates in particle form, each particle comprising: A) a matrix consisting of a nonextruded particle of an olefin polymer or copolymer, having a porosity, expressed in percentage of voids on the volume of the particle, higher than or equal to 15%; B) one or more additives, pigments or fillers, or combinations thereof, deposited on the surface of the matrix (A) and/or inside it...

An adhesive composition comprising (A) 100 parts by weight of a copolymer latex mixture consisting of (a1) 50 to 95 % by weight (expressed as a solid content) of a butadiene-styrene-vinylpyridine copolymer latex and (a2) 5 to 50 % by weight (expressed as a solid content) of a carboxylated butadiene-styrene base copolymer latex and (B) 10 to 30 parts by weight of a resorcin-formalin resin, whic...

In an electrical control device, two printed-circuit boards which are located parallel, one on top of the other, are used in the casing, which printed-circuit boards are connected to one another at points and, on their board edge, support coupling parts which come to rest in a front wall of the casing after assembly. In order to develop a compact control device which can be assembled quickly and d...

A laser (L) provides a beam processed through a lens (L1) a half wavelength plate (L2), a beam splitter (P5), a cylinder lens (ZL) and objective lens (OL). The signal reflected from the surface is received by a 4 quadrant photodetector (ABCD) with outputs summed by an amplifier to generate a data signal (HF). The amplitude of the signal is a measure of the laser power and is used by a regulator (R...

The description relates to the use of a nucleation agent in a process for the production of loose-fill packing from starch. The nucleation agent is applied to the surface of starch granulates in finely divided form in quantities of 0.1 to 0.2 % of the weight of the granulates and in a grain size of about 50 mu . The granulates thus coated with nucleation agent are taken to an extruder (14) in whi...

The vehicle is controlled by a throttle pedal (10) and brake pedal (20). The displacement of the controls is monitored and the displacement signals used to generate the control signals for the vehicle drive. A safety circuit (40) monitors the signals from the controls and operates a failsafe braking cycle if the throttle control jams. The failsafe braking cycle is release by re-applying the brake ...

The invention relates to a dressing and wear measuring apparatus for grinding and lapping machines, suitable in particular for use on tool discs used at the front face for the plane-parallel machining of workpieces, which apparatus is distinguished by the fact that the dressing head and measuring head, when lying one behind the other, can be retracted and extended with separate guide systems on a ...
