The ring-shaped members (2) are placed in annular recesses provided in the laminating jig (13) and in correspondingly formed annular recesses (11) provided in the bag (10). Then stringers (3) are placed on the ring-shaped members (2) with the convexed parts (9) fitted in the recesses (7) of the ring-shaped members, so that a framework of the ring-shaped members (2) and the stringers (3) are formed. The framework (3) is thereafter fitted on a winding jig (15), and a fiber-reinforced prepreg (16) of tape form is wound around the framework. The entire assembly is subjected to curing and bagging processes. The jigs (13, 15) and bag (10) are removed finally.

Abstract: Method of preparing cheese for distributino through first concentrating milk through separation of the whey and then adding additives necessary for cheese production, e.g. rennet, and packaging in distribution-ready packagings. Through concentrating the milk to such an extent that it is given the same DM content as is desired in the finished cheese (what is known as full concentration) the milk and the added additives can be packaged in such a manner that both the coagulation of the milk and forming and maturing of the cheese essentially occur entirely in the said packagings.

Abstract: A semiconductor body (1) defines at least one active device. In the example shown in Figure 1 complementary n channel and p channel IGFETs (10 and 20) are provided. An electrically conductive region, which may form the gate conductive region (101 and 102) of the insulated gates (11 and 21) of an IGFET, is provided on a first major surface (2) of the semiconductor body (1) and is encapsulated within a covering insulating region (300,400). An area (100a) of the electrically conductive region (101 and 102) contacts a relatively highly doped semiconductor region (50) provided adjacent the one major surface (2) and electrical contact is made to the electrically conductive region (101 and 102) via a conductive track (205) provided on the first major surface (2) and a conductive path provided by the relatively highly doped semiconductor region (50). It is thus not necessary to form a contact opening through the covering insulating region (300,400) to enable contact to the electrically conductive region (101 and 103) and accordingly electrical interconnections can overlap or cross over the encapsulated electrically conductive region (101 and 102).

Abstract: Air bags are located at different positions within a vehicle. Squibs serve to fire and activate the air bags respectively. An acceleration detecting device is provided in common to the squibs for detecting an acceleration of the vehicle upon a collision of the vehicle and executing a switching operation in response to the detected vehicle acceleration. Constant-current circuits supplied with an electric power from a vehicle battery feed constant electric currents for a firing operation to the squibs respectively in response to the switching operation of the acceleration detecting device. An energy storage device serves to feed a backup electric power to the constant-current circuits when the supply of the electric power from the vehicle battery is cut off. Each of the constant-current circuits includes a first transistor for feeding an electric current to the related squib, a first resistor for detecting a level of the electric current fed to the squib, a second transistor conducting an electric current with a level which depends on the electric current level detected by the first resistor, and a second resistor for generating a voltage which depends on the electric current conducted by the second transistor and for controlling the first transistor in response to the generated voltage.

Abstract: An electrochemically actuated control valve is disclosed which represents a new class of devices for fluid flow control. The valve is activated by an electrochemical motor which converts DC electrical energy into compressed gas energy suitable for producing mechanical work. The mechanical motion is typically reciprocating linear motion. This linear displacement can be accurately controlled, can be modulated at high frequencies and responds quasi-instantaneously to the applied DC voltage. The electrochemical valve can be computer or microprocessor-controlled.

Abstract: A novel hydraulic set packer is set independently of the setting of two other straddle packers, the straddle packers being set by other than hydraulic means, such an by inflation or compression. If the straddle packers are set by inflation, a novel inflate deflate valve in associated with both straddle packers for providing an additional method to deflate the inflatably set straddle packer. If the straddle packers are compression set, it may be necessary to allow a top straddle packer to set only after the bottom straddle packer in already set, that is, the top straddle packer is not permitted to set when the straddle packer assembly is being pushed into a deviated/horizontal borehole or through a restriction in the borehole. Accordingly, a novel hydraulic ratchet, disposed above a bottom straddle packer on a tubing but below the top straddle packer on the tubing, will enable the top straddle packer to net only after the bottom straddle packer in already set.

Abstract: The invention discloses an impeller for pumping hot fluids in nuclear reactors, which comprises an impeller body (1), the latter having a bearing sleeve (2), and a shaft section (3) which transmits the driving torque. Together with the shaft section (3), an insert (4), which is connected to the non-rotating part of the pump, forms a flow channel (12) to guide an auxiliary flow which supplies cool reactor fluid in the direction (9) of flow to the impeller in the case of injection operation and leads hot reactor fluid in the direction (10) of flow away from the impeller for cooling in the case of leakage operation. Along its axis (5) of rotation, the impeller has a blind hole (6) which extends into the shaft section (3) and has an inside diameter (17) which is more than 30 % of the outside diameter (18) of the shaft in order to reduce the axial heat transfer surface to the shaft section (3). The blind hole (6) is sealed with a cover (7) and forms a cavity (14) which is evacuated or filled with a poor heat conductor. The transition zone between the impeller body (1) and the shaft section (3) is covered on the outside by a protective sleeve (11).

Abstract: The valve designed for being used in respirators adapted to operate exclusively in the superatmospheric pressure breathing regime is controlled by a straight stay or stays (1) immediately confining a space or cavity (8). In inoperative state where the cavity inlet is not exposed to any medium pressure, the stays (1) are tight and hold a valve (6) open until the pressurized medium has entered therethrough the cavity (8) where a superatmospheric pressure is produced consequently. Thereby the straight stay or stays (1) are bent, get shorter and release the valve (6) which cuts off the medium flow. By aspirating from the apparatus, the superatmospheric pressure in the cavity (8) drops so that the stays begin to reassume their original shape and to reopen the valve (6). The cavity (8) is air-tightly separated from the ambient atmosphere by cementing an elastic fold onto the periphery of stay (1), which fold is followed by a sealed forechamber (9) closing the entire automatic stay system and allowing the medium to be let in and out.
