A method for controlling a continuously variable transmission (6) having a pair of pulleys each of which includes a groove defined between a stationary pulley element (8,14) and a movable pulley element (10,16), including the step of using hydraulic oil for increasing and decreasing the width of the groove to respectively decrease and increase the radius of rotation of a belt (4) looped around the...

A process for photo-ablating at least one stepped opening extending through a polymer material, the stepped opening being useful as a fluid carrying passageway such as an inkjet nozzle in a nozzle plate of an inkjet printer. In a first step, the polymer material (1) is exposed to a first beam of laser energy (2) to ablate the polymer material (1) so as to form a first hole (3) which extends into t...

The system involves cooling of a mincer section. The mincer section comprises a mounted feed-in worm, a mincer housing and a funnel in which the meat to be minced is fed in. The mincer section is carried out by means of several Peltier-effect modules. The transmission of the thermal flow from the Peltier-effect modules to the various parts of the mincer is by means of several specially manufacture...

The control of under-pressure in the suction system of a textile machine with a number of workstations, each with different suction requirements, sets the rotary speed of the suction system drive motor to cover the basic need of the whole machine. When an indication is received at the control, that an increased underpressure supply is required, the motor speed is increased before the raised underp...

A two stage reaction for the production of steel from iron carbide is carrie d out in two separate but interrelated reactors (1, 36). In the first reactor (1), iron carbide, with slag formers, is fed into a feed end (2) and the reaction is well-mixed by the vessel geometry, the stirring action of below- surface injection of oxygen and iron carbide feed, and the evolution of gase s from the liquid ...

L'invention porte sur un appareillage de mesure concernant des fluides dans un rotor ou un condenseur (2) durant une rotation. Cet appareillage comporte un détecteur électrique ou magnétique (4) monté sur la paroi interne d'un conteneur (2) et des organes (5A, 5B) destinés à assurer une transmission sans contact et intermittente de signaux de mesure en provenance du détecteur et à destination d'un...

The present invention relates to a novel method for the diagnosis of Alzheimer's disease using cerebrospinal fluid. More particularly, this method consists in contacting a sample of cerebrospinal fluid which contains a glutamine synthetase, having an apparent MT of about 42 000 daltons, with a labeled antibody specific for said glutamine synthetase under conditions that allow the formation of glut...

The flame detection system uses a microprocessor with a fuzzy-controller for analysis of the radiation intensity variations resulting from the flame, with signals outside a defined frequency band identified as interference signals. The mean and limit frequencies of the detected radiation are determined, with detection of periodic and non-periodic signals, the periodic signals with a mean frequency...

An improved closed cell polymer foam and foaming agent involving the use of a hydrogen-containing halocarbon blowing agent (e.g., HCFC-22) in combination with an effective amount of a hydrogen bond forming blocking agent (e.g., organic ether, ester or ketone). The presence of the blocking agent is shown to significantly reduce the escape of blowing agent from and entry of air into the foam resulti...

A curing mold (20) for pneumatic tires includes a plurality of segments (22) which are detachably adjoined with each other in a direction corresponding to the circumferential direction of a product tire. Each segment has a plurality of fitting pieces (26) with fixing portions (42, 44) at both ends, at least one of which is complementary to part of the land portion of the tire. The fitting pieces (...
