Patent EP-0170178-B1 (EP)
IPC: B29C61/00
Filed: 1985-07-20
Granted: 1989-05-24
Abstract: A removable core for use in the production of tubular structures from fibre reinforced resin materials. The body of the core is composed of a foam material which softens or collapses under the action of heat sufficient to cure the resin material but is hard and cross-sectionally dimensionally stable under less heat than that. The core is provided on the outside with a heat shrunk plastic tube or hose which closely embraces the foam body and serves as a coating therefor, thereby enhancing the rigidity and stability of shape of the core and imparting thereto a smooth surface.

Title: Method for preparation of fat-continuous dispersion
IPC: A23D7/00
Filed: 1985-07-17
Granted: 1990-12-19
Abstract: Butter, margarine and melanges as well as spreads containing less than 80% fat are prepared by passing an oil-in-water cream containing 40 to 70 wt.% oil, of which oil 15 to 65 wt.% is in the solid phase, through a static mixing unit, pressure valve or the like. Preferably, the cream is a physically ripened cream containing 20-40% solid fat calculated on the total weight of the fat present in the cream. Preferably, the pressure drop is about 2 to 20 bar and the attendant temperature rise less than 10 DEG C. Inversion of the oil-in-water emulsion occurs with a minimum of working. A high proportion of fat globules in the ripened cream can thus be present in the product.
Patent EP-0176529-B1 (EP)
IPC: B60K17/28
Filed: 1985-04-01
Granted: 1989-11-08
Abstract: A system for controlling the engagement of a friction clutch (12) which is particularly suitable for controlling such a clutch in a tractor power take-off drive. The system includes two sensors (18, 19) which provide signals indicative of the input and output speeds of the clutch during the engagement process. These signals are compared in a microprocess control circuit (25) to produce comparison signals. Predetermined target accelerations for the clutch output (17) are set in relation to the full range of comparison signal values. The actual acceleration achieved by the clutch output is determined and the target and actual accelerations of the clutch output are compared and an error signal produced which is indicative of the disparity between the target and actual accelerations. Clutch engagement pressure is adjusted in response to the error signals so as to achieve the target accelerations using a solenoid operated valve (14) and the so-called pulse width modulation technique.
