Title: Control valve device
IPC: F15B13/043
Filed: 1988-07-16
Granted: 1992-12-23
Abstract: Control valve devices, in particular for antilock device on pneumatically operatable vehicle brake systems, have a controllable inlet valve (47, 2) and a controllable outlet valve (9, 10). A pressure medium output chamber (3, 7) can be connected via the inlet valve (47, 2) to a pressure medium intake chamber (48, 50) and via the outlet valve (9, 10) to the atmosphere. 
<??>Since, in normal operation (uncontrolled operation), the reduction in pressure in the pressure medium output chamber (3, 7) occurs via the inlet valve (47, 2) and the pressure medium intake chamber (48, 50), the reduction in pressure is considerably delayed. 
<??>In order to overcome this disadvantage and to shorten the times taken for the reduction in pressure, the pressure medium intake chamber (48, 50) is subdivided into a first sub-chamber (48) connected to the inlet valve (47, 2) and a second sub-chamber (50) connected to the pressure medium intake (39), as shown in fig.1. The first sub- chamber (48) and the second sub-chamber (50) can be connected to one another via an additional valve device (38, 42) designed as a non- return valve directable onto the first sub-chamber (48) into the open position. 
<??>By this measure it is ensured that in the event of a reduction in pressure the return flow of pressure medium from the pressure medium output chamber (3, 7) occurs not via the pressure medium intake chamber (48, 50) but via the outlet valve (9, 10) directly into the atmosphere, thereby resulting in an accelerated reduction in pressure in the pressure medium output chamber (3, 7) and hence in the consuming unit.

Granted: 1991-03-27
Abstract: An improved leaf spring clamp is provided, particularly for use with composite material leaf springs (50), to securely fix the position of the leaf spring (50) relative to a wheel axle or other suspension system member, such as in the suspension system of a motor vehicle. The leaf spring clamp comprises a rigid clamp base (30) and a clamp plate (40). The clamp base (30) forms a channel adapted to receive a wedge insert (60,70). The inner surface of at least one side wall of the clamp base (30) fairs from both ends into a channel-widening concavity (34a,34b), preferably at the longitudinal midpoint of the channel. The wedge insert (60,70) forms an inner channel adapted to laterally jacket the leaf spring (50). The outer surface of the wedge insert substantially fills the clamps base channel, providing a convexity adapted to register with the channel-widening concavity of the clamp base. The clamp plate (40) attaches to the clamp base (30) to clamp the leaf spring (50) between them under a preload. The clamp plate (40) and clamp base (30) together comprise pin-and-hole means (37a,37b,47a,47b) such that they can easily be attached to each other to yield a degree of compressive pre-load on the resilient insert.

Granted: 1993-03-10
Abstract: Transmitter and receiver devices (2, 3, respectively) are included in an active optic proximity fuse for realizing increased resistance to aerosols. The transmitter and receiver units operate with optical radiation (6, 7; 8, 9, respectively) and include a signal processing unit (4) which is intended to react to a target (10) located in a sensing regin (AV) and reflecting optical radiation emitted from the transmitter device to the receiver device. The sensing region displays, most proximal a carrier (1) of the proximity fuse, an inner sensing limit which is located at an inner distance (L) from the carrier. The signal processing unit (4) operates with preparatory signal processing and/or time measurement of reflected signals when the target is located within the sensing region, and emits an activation signal only when the target passes the inner sensing limit.

Abstract: The device for the obstruction of ventilation installations consists of a U-shaped frame 3, in which there are arranged, in the direction of flow and at a distance from one another, lamellae 4, 6, 7, 8, 9, 10 made of a material which in the event of fire foams and hermetically seals the cross-section. Of these lamellae, every second lamella is mounted pivotably about its vertical centre axis so that the intermediate space between two firmly installed lamellae can be sealed. At temperatures up to approximately 65 DEG C, the obstruction device does not respond for at least an hour, whereas at a trigger temperature of approximately 70 DEG C, by means of a control device, a pivoting movement of the rotatably mounted lamellae begins, and at at least 100 DEG C the sealing material foams. In the range up to 100 DEG C, the obstruction device therefore operates reversibly. <IMAGE>

Title: Water-in-oil dispersion and process for preparing such dispersion
IPC: C09K23/56
Filed: 1990-05-04
Granted: 1992-12-09
Abstract: The present invention is concerned with a process for preparing a dispersion comprising a continuous fat phase and a dispersed gelled aqueous phase, wherein a water-continuous composition, containing at least 1% gelatin by weight of water, is cooled from above the gel setting temperature of the water-continuous composition to below said gel setting temperature and subjected to such conditions of shear that the water-continuous composition is converted into small gelled aqueous beads, after which a fat-continuous dispersion is formed while maintaining the temperature at below the gel melting temperature. The process according to the invention offers the advantage that it enables the preparation of water-in-oil dispersions of extremely low fat content even when using aqueous phase compositions which in the ungelled state do not possess a high viscosity. Also the present process makes it possible to incorporate ingredients into the aqueous phase which, in the absence of a gelled structure, would promote and actually induce the formation of an oil-in-water dispersion. Another aspect of the present invention is a dispersion comprising less than 23% by weight of a continuous fat phase and a dispersed gelled aqueous phase containing gelatin at a concentration of 1 to 7 times its critical concentration and optionally a combination of one or more gelling agents other than gelatin at a concentration below their critical concentration.

Abstract: A game machine has a win judgment (29) stores information as to whether there is a win or not for each numerical value constituting a series of numerical values and its relation with winning ranks. A numerical value assigned with at least one special win allowing a big prize is located at one end of the series of numerical values. Only at the first game, one numerical value is sampled from the series of numerical values and such sampled value is used as a basis for a win judgment of the first game. In a second game and in games thereafter, such sampled numerical value is used as an initial value, a prearranged numerical value, which is shifted toward the end of the series of numerical values in proportion to the number of times for playing a game, is used. A win judgment is performed based on this prearranged numerical value. When the prearranged numerical value reaches the end of the series of numerical values, one cycle of games is over, and the next game becomes the first game for the next cycle of games.
