Patent EP-0235114-B1 (EP)
IPC: B28B1/29
Filed: 1987-01-12
Granted: 1991-01-09
Abstract: This publication describes a slipforming extruder for production of hollow-core concrete elements (23), movable in respect to a casting bed (4) and comprising a frame (18) which is movable, e.g. supported by wheels (19), and provided with at least two adjacent auger flights (2, 25) with flights (5) and a core-forming mandrel (3), attached to the final end of each auger flight (2). Furthermore, the machine comprises a primary drive and power train system (7, 15, 16, 17) for rotating the auger flights (2) and a feed apparatus attached to the frame (18), e.g. a hopper (1), for feeding the auger flights (2) with the concrete mix to be cast. According to the invention, a secondary drive and power train system (8...14) moves the adjacent auger flights (e.g. 2 and 25) in a synchronized and counterphased reciprocating manner in the axial direction. Because the machine disposes of core vibration, it achieves a low level of generated noise.

Date Mar. 24, 1988An apparatus for measuring physical properties of blood is disclosed. Two reservoirs are provided connected to a receptacle means by at least two elongated tubes. A punching station located along the two tubes permits the simultaneous punching of holes to simulate bleeding in the tubes. The bleeding of the tubes is monitored to indicate the haemostasis properties of blood flowing through the elongated tubes. Monitoring is effected by measuring the downstream pressure of a punched tube. Alternate embodiments include the addition of third channel having a collagen material within the channel. Platelet aggregation on the collagen material is observed as a measure of haemostasis properties of the blood.

Abstract: A known procedure is used to prepare liposomes of bipolar lipid membranes which are permeable and hence ''leak'' their contents at a rate which is variable by choice. The liposome is supplied with medication or cosmetic material for the oral cavity, or specifically for the teeth and gums. The liposome is then attached to a molecule that has affinity for the hydroxyapatite. Thus, the liposome will bind to oral cavity hydroxyapatite and bathe the surrounding support surface with its contents for extended hours of service.

Granted: 1992-12-16
Abstract: A digital transmission system and method for coherent optical systems in which a source signal (1) is frequency modulated by digital information and caused to be incident on a birefringent medium (20). Modulation signals are produced having a polarisation which is dependent on the frequency of the source signal. The information can be regenerated by processing only one the modulation signals and thus only one need be transmitted. Further modulation signals may be transmitted to enable error checking at the receiver.

Abstract: Fluidized-bed counter-jet mills are gas-jet mills with which extremely fine milling results can be produced with very little wear and tear. An improvement in the milling results can be achieved by cooling the gas jets with a refrigerant, but the improvement that can be achieved is not substantial and the consumption of refrigerant is very high. In order to lower the consumption of refrigerant while considerably improving the fineness of the milled material, the coarse material which is separated by the grader of the mill is cooled by the refrigerant within the fluidized-bed counter-jet mill and fed back into the milling chamber. Liquid nitrogen is the preferred refrigerant with which the sump of the mill is cooled.

Abstract: A card reader (2) for reading e.g. a "smart card" (1) having contact pads (7a,7b) thereon which are connected to an information store such as an integrated circuit. The card reader includes an enclosed sliding carriage (4) with wedge-shaped cams (9a,9b) that urge leaf contacts (6a,6b) into engagement with the contact pads (7a,7b) on the card (2) when it is inserted into the card reader. A microswitch, operated by the card, supplies power to circuitry for enabling the card to be read. The card reader can be made very slim, e.g. 5mm. Also, since the leaf contacts do not engage the card except when the card is fully inserted there is no wear on the card or the leaf contacts during insertion or withdrawal.

Abstract: A microwave proximity switch includes a microwave oscillator circuit having a micro strip line as an inductor thereof so as to sense a change in an oscillation frequency or output from the oscillator circuit caused by a variation in an impedance of the micro strip line due to a loss which takes place in a leakage magnetic field from the micro strip line when an object approaches the leakage magnetic field, thereby detecting an object in the neighborhood of the switch.   A microwave proximity switch includes a microwave oscillator circuit having a dielectric resonator. An object in the neighborhood of the switch is detected by sensing a change in a state of an oscillation frequency or output from the oscillator circuit caused by a variation in an impedance of a circuit including the dielectric resonator due to a loss which takes place in a leakage magnetic field from the dielectric resonator when an object approaches the leakage magnetic field.

Abstract: The present invention is concerned with a process for preparing a cheese product containing polyol fatty acid polyesters, comprising the following steps:   (a) preparing a water and oil containing mixture comprising from 1.2-40 wt.% oil, by combining a fatty composition containing at least 40% polyol fatty acid polyesters by weight of oil with an aqueous composition, (b) homogenizing said mixture so as to obtain a filled milk having an average oil droplet size of less than 20 microns, (c) preparing a cheese milk by combining the filled milk of step (b) and an aqueous composition containing at least 2 wt.% milk protein, (d) adding a starter culture and/or coagulant to the cheese milk and leaving it to coagulate (e) optionally cutting the coagulum to provide curd particles in whey, and   (f) separating the whey from the curd.   The present process offers the advantage that it enables the preparation of cheese products wherein a substantial amount of milk fat has been replaced by polyol fatty acid polyesters without any significant adverse effect on the quality of the final product. Another aspect of the present invention relates to a cheese product containing more than 4 wt.% polyol fatty acid polyesters and more than 6 wt.% triglycerides, the total fat present in the cheese having an N10 value of more than 25 and essentially all triglycerides originating from milk fat.
