Patent EP-0292776-A1 (EP)
Inventor: DIETERLE FRANZ
IPC: H04N5/05
Filed: 1988-05-10
Abstract: 1. Circuitry for automatically switching the control speed of a phase-control circuit. 2.1. The switching is, especially in conjunction with different signal sources employed with a television receiver, either difficult or possible only by reserving prescribed program locations. The advantage of the invention is that it becomes possible to switch over without great expenditure to the higher control speed only while necessary and back to the low speed when it no longer needs to be high. 2.2. The invention is characterized in that a control circuit 12 increases the control speed, independent of whatever signal source is being employed to produce the picture, only during vertical flyback. 2.3. The circuit can be employed in television receivers to reproduce both broadcast television signals and video signals from a recorder connected to the receiver.

Abstract: In a process for dispersing or redispersing relatively large crystallites of Group VIII noble metal species on a porous inorganic support, the supported species is contacted with nitric oxide, either alone or in admixture with a source of halogen such as Cl₂, and thereafter any sorbed nitrogen oxide(s) and halogen are removed by purging with an inert gas. The treated metal-loaded catalyst demonstrates substantially increased benzene hydrogenation activity (BHA) compared to the same catalyst prior to treatment.

Abstract: A penumatic piston (11) has an output element (12) whose bore (17) provides a cylinder for a piston (18) which is secured to a fixed part (21) of the actuator and which has flow restrictors (22) through which hydraulic fluid is displaced as a result of movement of the output element (12). The restrictors (22) are normally shut by a valve (24) to provide a hydraulic lock which prevents movement of the output element (12). The valve (24) can be opened by an electro-magnetic actuator (27) which is energised in unison with a valve (13) through which actuating air is supplied to the piston (11).

Abstract: A power source (RX) for a car radio receiver which is kept on-state is temporarily turned off by a starter switch (12). However, three-second timer (20) is arranged between the power source (RX) and an antenna motor (M) to keep the antenna motor (M) not driven for three seconds even when the power source (RX) is shut off. This prevents the motor antenna to be unneces­sarily lifted and lowered every time when the starter switch is made on and off.

Abstract: Il est bien connu que l'emploi de l'agent gonflant monofluortrichlorométhane, également appelé Fréon 11 ou R-11, pour la production de mousse de polyuréthane est très désavantageux en ce que le R-11 a un effet de décomposition sur la couche d'ozone entourant notre planète. Malgré de vastes recherches scientifiques il n'est toujours pas possible de produire un produit de remplacement R-11 facilement utilisable, capendant un tel produit de remplacement est décrit par l'invention. D'après ladite invention on utilise un mélange de substances spécifiques, pratiquement sans danger pendant l'utilisation et par ailleurs avantageux, mais dont les points d'ébullition sont si éloignées des températures de travail habituelles que chacune des substances, prise séparément, s'avère totalement inutilisable pour l'objectif à atteindre. Les deux substances primaires sont le trichloroéthane 1.1.1. et le R-22 dont les points d'ébullition respectifs sont de 75-76°C et de -41°C. Lorsque l'on mélange ces substances, et qu'on les mélange dans le composé à transformer en mousse, les conditions du procédé correspondent largement à l'utilisation du R-11, sans parler des autres avantages que l'on peut en tirer.

Abstract: A hierarchical key management system includes a number of secure terminals (1-500). These terminals provide secure access to a corresponding number of users (1-500). A user inserts a security activation device (SAD) or key into the secure terminal to access a secure connection through the established communication network (PSTN). A group of secure wireline terminals (1-500) is connected to a key certification authority (KCA). There may be several groups of key certification authorities (A,B,C) and corresponding secure terminal users (1-500). At the highest level, a key certification center (KCC) authorizes secure communications by the key certification authorities (KCA). In turn, the key certification authorities (KCA) authorize secure communications between the users. As a result, if one level of key management is compromised, other levels and users are not affected.

Abstract: In a spring-loaded brake cylinder (5) for vehicles, especially utility ones, a piston tube (11) connect to the spring piston and extending out of the cylinder housing is sealed at its end with an end or pressure member (13); in the case of combination of the spring-loaded brake cylinder (5) with a service brake cylinder (3), the pressure member (13) can act on the actuating mechanism of the service brake cylinder (3). The pressure member (13), which is preferably screwed to the piston tube, has a device which prevents twisting relative to the piston tube and thus detachment from the latter. The device consists of a retention ring (33) which, situated between mutually facing bearing surfaces of the pressure member and the piston tube, engages by means of projections (35, 37) in recesses (25, 31) of the pressure member and the piston tube, such that a rotation of the pressure member relative to the piston tube is prevented. The retention ring (33) is slotted and, after the pressure member has been screwed in, is pushed down from the outer periphery of the piston tube into its locking position between pressure member and piston tube. <IMAGE>

Abstract: The invention relates to a brake system with antilock device for a motor vehicle. According to the invention, a two-channel design is proposed having only one sensor (S1, S2) on each front wheel (VL, VR), the antilock system engaging directly on the front wheels (VL and VR) only. The rear wheels are made to follow with the aid of a step piston cylinder arrangement (10) with an averaged brake pressure. Although, basically, an hydraulic and electronic two-channel system structure is present, an hydraulic 3-channel system is obtained, one channel being dependent on the other two. Thus, with simple design, in particular a good braking action on  mu split and increased safety are obtained since in the event of leakage on a front wheel the remaining three wheels can be braked; in the event of a failure of the rear wheel brakes, the braking capacity is maintained on both front wheels. In a further embodiment of the invention, two step piston cylinder arrangements (10) are used. <IMAGE>

Abstract: The histamine in a sample is determined by contacting the sample with a histamine binding agent, such as glass, which has been treated, e.g., with a polar organic polymer, to reduce the affinity of the agent for an interfering component of the sample while substantially retaining the agent's histamine-binding capacity. Such an agent facilitates determination of histamine in whole blood samples. Preferably, the agent is provided as a conglomerate of histamine-binding bodies, such as glass fibers, in a binder. Preferred binders are polyvinyl acetate, a vinyl acetate/ethylene copolymer, and polyvinyl alcohol or combinations thereof.
