Title: Upstream classifier for a multi-separator
IPC: B04C5/02
Filed: 1973-12-12
Abstract: Apparatus is described for classifying particulate matter of different densities that is entrained in a fluid flow stream and for selectively proportioning, on a density basis, the flow of particles to the inlets of plural separators. The apparatus includes a bend section of a duct system in which the particles are initially concentrated and a baffle disposed immediately downstream of the bend section which is operative to deflect the particles transversely across the path of the gas component. The particles are operated on by the gas to deliver the finer particles to one separator and the more coarse particles to the other separator.

Patent ES-437081-A1 (ES)
Title: 4-piperidylureas
IPC: C07D211/58
Filed: 1975-04-28
Abstract: Novel 1-[N-(p-fluorobenzoylpropyl)-4-piperidyl]ureas of the formula I below, in which R is a hydrogen atom, an acetyl group, an alkyl group with 1 to 3 carbon atoms or the phenyl group, are prepared by reacting a correspondingly substituted N-(4-piperidyl)-2-imidazolidinone with a p-fluorobutyrophenone which has in the omega position a group which can be eliminated under the reaction conditions. The products of the process can be converted into their physiologically tolerated acid addition salts. It is additionally possible for resulting compounds of the formula I in which R is hydrogen to be acetylated by reaction with acetyl chloride or acetic anhydride. The novel compounds show the typical range of effects of the neuroleptics and can therefore be employed as CNS-depressant agents, sedatives and tranquillizers.

Patent ES-469360-A1 (ES)
Title: Universal sequential dispensing pump system free of external check valves and having venting capability
IPC: F04B7/04
Filed: 1978-05-02
Abstract: A pump system having two moving parts consisting of a cylinder with a piston therein defining a pump chamber. An inlet part communicates with a dip tube which extends into a container and permits the product in the container to pass into the pump chamber. An outlet port allows for the product thus drawn to be dispensed from the pump chamber. The pump is actuated by pressure directed axially on the piston, forcing it into the cylinder. Fitted with a return device the piston is allowed to reciprocate in the cylinder alternating between a suction and compression stroke. During the suction stroke product is drawn into the pump chamber by way of the inlet port while the compression stroke provides for the dispensing of the product thus drawn via the outlet port. The system is equipped with passages and channels sufficient to accomplish the operation of drawing and dispensing the product in addition to providing for the venting of the container. The suction stroke provides for air to be drawn through the outlet part from the ambient into the pump chamber, advantageously removing any residual product from the outlet part where this is desirable. In certain applications the air is drawn into the pump chamber to assist in the dispensing of the product during the compression stroke. The introduction of air into the pump chamber also assures the presence of an air pocket therein, thereby maintaining a resiliency in the system thereby preventing piston "hang up". Embodiments of the pump system are disclosed having a vertical pump axis equipped with a vertically reciprocal finger actuated button on having either a vertical or horizontal axis with a trigger actuator. Different cylinder and piston configurations are disclosed facilitating commercial applications of the system.

Title: Double filter papermaking machine
IPC: D21F9/02
Filed: 1979-01-12
Abstract: A double filter papermaking machine comprising two filters guided over a dewatering cylinder. A first one of the filters contains a linear section or path located in front of the cylinder. A domed dewatering or slide shoe, shorter than such linear section, is arranged ahead of the cylinder. The second filter is equipped with an adjustable guide roll, by means of which it is possible to regulate the contact location of the second filter at the first filter, and specifically, between a location disposed at the starting region of the shoe and a location arranged after the shoe at the dewatering cylinder. A regulation device or regulator can be provided which contains a feeler for sensing the position of the water line at the dewatering cylinder. As a function of signals transmitted by the feeler the regulator adjusts the guide roll in a manner such that with a displacement of the water line from a reference position opposite the direction of movement of the filters the contact location is adjusted in the direction of movement of the filters and vice versa.
