The inner of a cylinder (1) is divided into a first and a second chamber (2)(3) by a partition (1a) where a first chamber oil inflow hole (1c) is formed. The first chamber oil inflow hole is opened and closed by a first chamber double check valve (9) and a second chamber oil inflow hole (3d) is operated by a second double check valve (11). The interval between the first chamber check valve and t...

A device for characterizing the formation of a sheet material is described. The device comprises a formation sensor (10) for measuring the basis weight of the sheet material as the material passes through the sensor, and signal processing circuitry which receives a basis weight signal from the formation sensor and which produces three types of outputs, which outputs characterize: (1) the magni...

The invention permits an inexpensive, flexible further processing of tabloids to smaller format double and multiple folds. In at least one conveying conversion means with in each case at least one removal station (19', 19'', 19'''), preferably simultaneously several starting products are removed, which are then further processed in parallel as clusters. The clusters are jointly conveyed by conveyi...

In a technique for producing a three-dimensional holographic display which is updatable in real time, a spinning lens device (28) intercepts a two-dimensional display on a projection television receiver (14) and transforms the display into a three-dimensional holographic display in free space. The holographic display is modifiable by a control room operator and process control variables can be rea...

A connector bank for cable wires (2,3,4) of telephone cables such that two cable wires (2,4 or 3,4, resp.) connected with each other over the connector bank can be separated from each other, with no need to loosen the respective contact connections. For this, the invention provides for each connecting element (7) a plug (6, 6a) with a contact lug (24, 24a) for insertion into the center contact (11...

The process and the related equipment are based on two resin packed ion exchange columns (4, 10) through which the juice (S) to be defecated is flowing. In the first column (4) the juice is partially defecated through ion exclusion thus producing molasses (M) with a satisfactory commercial value, while the defecation process is completed in the second column (10) with separation of the non-sugar r...

Self-supporting bodies are produced by reactive infiltration of a <> typically resulting in a composite comprising a parent metal boride and metal. The mass to be infiltrated may contain one or more inert fillers admixed with the boron source to produce a composite by reactive infiltration, which composite comprises a matrix of metal and parent metal boride embedd...

A button attaching machine has a chute assembly for conveying button parts and a blocking device for preventing button parts from falling from a detachable intermediate chute of the chute assembly when the intermediate chute is detached. The blocking device comprises a spring-loaded plunger supported by the intermediate chute adjacent to a lower end thereof and reciprocably movable in a plane perp...

A process for charging a sealed nickel-cadium storage battery in a time on the order of three to fifteen minutes. Charging is performed at a constant charging voltage which is lower than the voltage at which hydrogen is released at the negative electrode of the storage battery. Charging is terminated when the charging current intensity of the storage battery registers a significant increase follow...

A fuel cell in which the sealed portions formed at the peripheral edges of gas flow passages of a gas separating plate are turned so that they have a U-shaped cross section in the direction of the lamination so as to provide for elasticity. A filling member is filled in the interior of the sealed portions. This gas separating plate is used to respectively form gas flow passages through which diffe...

The selection switch for selecting the resistance value from 0 to 1x10n where n is constant with only one contact has 4 types of resistor and switch combinations. The first one is a combination of 10 switch and series connection of 1,1,2,1,2,3 resistors. The second one has a resistor series connection of 1,1,1,2,1,4 . The third one has a resistor series connection of 1,1,1,1,1,5 . The four...

A device for fixing cables E on a cable ladder K consists of a clamp 10 which is attached to the cable ladder in such a way that it is removable and comprises a pair of holders 11A, 11B which can be positioned one on each of the side pieces S of the ladder and arranged to engage by means of a hooked part 14 on one long edge of the adjacent ladder side piece and with a locking device 16 to engage a...

A joint structure has a clamp (6) manually operated by an activating member (7). A yoke-shaped holder (8) is movably mounted in a recess (9) formed in the load carrier support (2). The holder contains the actuating member and allows it to pivot. - A load carrying beam (5) is secured to the holder by clamping movement of the actuator member in one direction causes the clamp to close and grip the ve...
