Patent EP-0227579-A2 (EP)
Inventor: PHILLIPS JAMES STEWART
IPC: F01D5/18
Filed: 1986-12-18
Abstract: The wall of a hollow turbine airfoil has a longitudinally extending coolant outlet slot in its external surface which intersects, along its length, a longitudinally extending cylindrical channel within the wall. Metering passages extend from the inside surface of the airfoil wall to the cylindrical channel and direct a metered amount of coolant into the channel in a manner which results in a swirling motion being imparted to the fluid as the fluid diffuses within the channel. The coolant is thereupon ejected from the channel through the slot in the external surface as a film on the external surface of the airfoil along the length of the slot. The swirling of the fluid within the cylindrical channel helps diffuse the fluid such that the outlet slot becomes completely filled with coolant, whereby a film of coolant is created on the airfoil surface downstream of the slot over the full length of the slot.

Abstract: A thermoplastic adhesive is applied to at least one side of the paper to form sticky areas and, after the paper has been printed, is activated by heating and the sheet of paper is adhered together at predetermined points by application of pressure. To simplify mass production of paper products to be printed and to give the user many options for applying the final sticky areas, it is proposed that the thermoplastic adhesive be applied uniformly and finely to the entire surface of the paper in an amount of less than 50 g/m<2> and that individual predetermined sticky areas are not formed by heating and pressing until after the steps of printing, copying or the like.

Abstract: A three-color stripe filter comprising Ye, G and Cy color filters are arranged on an image sensing surface of a solid-state image sensor (1), and sensed image output is sampled and separated for respective colors by sample-hold circuits (3, 4, 5). On the other hand, color temperature detecting sensors (S1 to S3) receive light of an object through a similar three-color filter and output the relative color temperature levels. A first comparator circuit (9) controls the gain of a first amplifier (6) in response to the difference between the color temperature levels of Ye and G, and a second comparator circuit (10) controls the gain of a third amplifier (8) in response to the difference between the color temperature levels of Cy and G. As a result, the average values of outputs derived from the amplifiers (6, 7, 8) become equal, so that a Moiré component in a luminance signal component is eliminated.

Abstract: Air intake systems suitable for resonance charging on internal combustion engines take up considerable space owing to the resonance tubes and resonance chambers required. In order to keep this space to a minimum and at the same time to achieve a compact air plenum chamber the invention proposes to arrange the two resonance tubes coaxially one after the other in a first plane and the two associated resonance chambers likewise coaxially one after the other in a second plane lying above the first. Transition apertures to the resonance tubes are provided at both ends of the resonance chambers. A controllable device is provided in the common centre wall of the two resonance chambers in order to cancel out the unwanted resonance system occurring there at higher engine speeds and to allow it to act again only at lower engine speeds. <IMAGE>

Abstract: The magnetic head incorporates a simplified write coil structure (9) and an improved and simplified combined magnetic bias (11) and sensor current structure (3). The active sensing current is utilized both to create an anti-parallel magnetic vector couple in a coupled film magneto resistive sensor (3) and to magnetically bias or torque the anti-parallel couple so that magnetization within the sensor films lies at an angle with the easy magnetic axis. Sensor current is fed in series through an electromagnetic coil (11) wrapped about the magneto resistive sensor (3) so that sense current simultaneously creates an anti-parallel magnetic vector couple in the sensor (3) and generates an electromagnetic bias field to torque the anti-parallel couple at an angle with the easy axis of magnetization. An improved spirally laid-out planar deposited writing flux coil (9) is positioned about the writing electromagnetic core (8) which greatly simplifies fabrication steps in making the device.
