Patent EP-0009660-B2 (EP)
IPC: E04G21/04
Filed: 1979-09-07
Granted: 1986-05-07
Abstract: To reduce the impact velocity of the concrete mass upon a surface, such as a wall, a branch line is arranged at the concrete conveying hose and at a point removed from the spraying nozzle. The branch line is intended to carry compressed air and opens into the surroundings. This branch line has a valve for regulating the quantity of compressed air which is to be withdrawn. By means of the branch or withdrawal line there is appreciably reduced the rebound of the concrete mass at the wall. The concrete mixture is initially pre-moistened to a constant moisture content before it arrives along the spraying or injection path and at the spraying or injection nozzle there is added thereto a constant residual water quantity. This method affords a continuously constant water content and renders possible reduced pressure of the conveying air since the concrete mixture is only pre-moistened at the conveying path.

Abstract: A cassette for sheet film has a cover and a bottom which are hinged to one another along a longitudinal edge of the cassette. Locking elements for locking the cover and bottom when the cassette is closed are arranged at the opposite longitudinal edge of the cassette. The cover and bottom cooperate to define a film compartment and the bottom has a rigid, flat wall for supporting a sheet of film. The cover has a window for exposing the film in the compartment and is further provided with a slot which slidably receives a shield for protecting the film against light until such time as the film is to be exposed. A resilient rim is mounted on the cover and extends around the window. The rim is arranged to press the margins of the film against the rigid wall of the bottom when the cassette is closed. The hinged connection of the cover and the bottom causes the rim to contact the film progressively as the cassette is closed so that the rim stretches the film flat over the rigid wall of the bottom. The pressure of the rim on the margins of the film after the cassette has been closed insures that the film remains flat regardless of the orientation of the cassette.

Abstract: Disclosed is an intumescent curable composition which contains as a resinous binder a flexible polyepoxide resin. The polyepoxide is cured with an appropriate curing agent adapted for the particular resin. An additive component is present which contains a mixture of materials which provide a source of     (i) zinc,   (ii) boron,   (iii) phosphorus, and (iv) an expansion gas upon thermal decomposition. The composition is capable of forming a carbonaceous char upon exposure to heat or flame, with the proviso that the cured, unburned composition has sufficient flexibility that it passes at least 10 continuous cycles of a cold cycle test without cracking. The cold cycle test involves the following steps: the composition is applied at a thickness of 0.5 inch (12.7 millimeters) to a 10 inch (0.254 meter) section of a 4W13 I-beam having two thermocouples attached to the surface, allowed to cure at ambient temperature for 16 hours, force cured for 5 days at about 60 DEG C and subjected to the cold cycle test. For one cycle, the beam is placed in a freezer operating at a temperature between about 0 DEG F (-18 DEG C) and about -10 DEG F (-23 DEG C) for sufficient time for the steel to reach a temperature between about 0 DEG F (-18 DEG C) and about (-10 DEG F) -23 DEG C as determined by the two thermocouples attached to the surface of the beam beneath the coating, removed from the freezer and a 50 square inch area (0.0323 square meter) of the surface warmed as shown in FIGS 1 and 2 by passing a heat gun (Model No. HG 50146, Alpha Division of Loral Corp, 14 amp: minimum temperature at tip 500 DEG F (260 DEG C)) a distance of 0.5 inch (12.7 millimeter) from the surface, uniformly over the surface until the surface temperature reaches 110 DEG F (43 DEG C) within a 3 minute period, as determined by a thermocouple moved about the surface and allowed to stand for at least 2 hours at ambient temperature.   <IMAGE>

Abstract: A method and apparatus for adjusting a zero point of a pressure sensor of an injection apparatus, which method and apparatus enable precise zero-point adjustment for the pressure sensor. Pressure of resin is detected by use of the pressure sensor, while a screw is moved, and a detection value corresponding to a detected pressure is obtained. The zero point of the pressure sensor is adjusted on the basis of the detection value. The detection value is obtained when the screw is moved in a state in which a flight speed is rendered lower than a screw speed. In this case, since the frictional resistance which acts on resin in the vicinity of the inner circumferential surface of the heating cylinder upon movement of the screw can be decreased, loads stemming from the frictional resistance are prevented from serving as disturbance against the detection value. As a result, zero-point adjustment for the pressure sensor can be performed precisely.

Abstract: PROBLEM TO BE SOLVED: To obtain a liquid crystal device, having wide viewing angle characteristics by controlling liquid crystal molecules, in such a manner that when a voltage is applied, the liquid crystal molecules are tilted in a first direction and when a voltage is further applied, the liquid crystal molecules are tilted in a second direction different from the first direction. SOLUTION: Liquid crystal molecules 103 are aligned almost perpendicular to substrates 101, 102 before a voltage is applied. Then when a voltage is applied, the liquid crystal molecules 103 are tilted as shown in Figure (b). Furthermore, by applying a voltage, the liquid crystal molecules 103 move in the different direction as shown in Figure (c) from the first moving direction of the molecules. By using such liquid crystal molecules 103 responding in two different directions, the characteristics of the liquid crystal display are improved. For example, polarizing plates 104, 105 are disposed with transmission axes 106, 107 aligned as shown by the arrows. In the state of Figure (a), light is not completely transmitted. In the state of Figure (b), light is not completely transmitted.  When the liquid crystal becomes as in the state of Figure (c), the liquid crystal molecules 103 are aligned at about 45 deg. with respect to the polarizing plate 104, light is transmitted by properly controlling the thickness of the liquid crystal layer.
