Title: Tdm switching networks
IPC: G02B6/38
Filed: 1977-01-21
Abstract: The time division multiplex switching network has switching network units (KE) which in each case effect a spatial and a temporal allocation of time channels formed on connected time division multiplex lines. For a switching network of this type, a structure is indicated in which, using a single type of switching network unit and starting with the lowest configuration levels, expansions of any size can be undertaken in simple fashion by adding further switching network units without any preparatory work having to be carried out for this purpose during a basic configuration. To achieve this, the time division multiplex lines in the form of groups of lines (1Z to nZ; 1S to mS) form a matrix-type arrangement at whose intersection points at least one switching network unit (KE) is in each case connected to the individual lines of two line groups (Z, S) via which connections between time division multiplex lines of the two line groups (S, Z) as well as connections between time division multiplex lines within the two groups can be set up, and the switching network units (KE) have a lower traffic handling capacity than that which corresponds to full accessibility. <IMAGE>

Title: Methoxybenzoic acid amides and their preparation
IPC: C07D295/192
Filed: 1960-01-22
Abstract: The invention comprises di- and trimethoxy benzoic acid amides, the nitrogen atoms of the amide groups of which form part of a heterocyclic ring, e.g. piperidine, pyrrolidine, morpholine, thiomorpholine, 2-methylmorpholine and hydrogenated derivatives of quinoline and isoquinoline.  The compounds are prepared by reacting a di- or tri-methoxy benzoylating agent, e.g. acid halide, ester or azide, with a secondary heterocyclic amine, preferably in the presence of an acid binding agent which may be a tertiary amine or an excess of the secondary amine.  Detailed examples illustrate the formation of amides of 3,4-dimethoxy- and 3,4,5-, 2,3,4- 2,4,6- and 2,4,5-trimethoxy-benzoic acids with morpholine, its 2-methyl and thio derivatives, piperidine and pyrrolidine.

Filed: 1937-01-29
Abstract: <PICT:0466705/III/1> The production of anhydrous metal halides, particularly chlorides, by reacting mixtures of carbon and compounds of the metals with halogens or halogen-yielding substances at temperatures sufficient to volatilize the halides formed is carried out in an electric resistance furnace using the reaction mixture as electric resistance.  Ores, minerals, or intermediate products of the metals may be used, and coal, coke, retort carbon, or graphite as the reducing agent.  The reaction mixture may be in granular or briquette form.  It may be coked prior to use, and may be preheated as by passing hot gases therethrough.  When mixtures of metal halides are volatilized they may be separated by fractional condensation.  The process may be carried out continuously in a furnace a having electrodes d, d1, reaction mixture being supplied at g and halogen gas at e.  Volatilized halides are withdrawn at f and reaction residues at h.  Examples relate to the production of beryllium chloride from a coked mixture of beryllium oxide, wood charcoal, and pitch, of beryllium and aluminium chlorides from a coked mixture of beryl, coal, and pitch, and of chromium and ferric chlorides from a coked mixture of chrome iron ore and coal. The production of chlorides of zirconium, thorium, titanium, tungsten, and molybdenum is also referred to.

Title: Improvements in governors for steam operated hydraulic systems
IPC: G05D13/00
Filed: 1919-02-04
Abstract: 142,547. Brunton, J. L., and Brunton, W. P. Feb. 4, 1919. Fluid governors; fluid relays.-In a fluid-pressure governor in which variation of pressure in the hydraulic system controls the steam valve of the steam pump, a ram f in the system actuates a lever a mounted on a shaft b and held in a central position by springs d. An arm g on the shaft b operates a piston valve h controlling the admission of steam to both sides of a differential piston operating the main valve m. The underside of the piston j is subjected at all times to full steam pressure by way of a central part k. Should the pressure in the hydraulic system rise, the lever a and the valve h are lowered, admitting steam to the upper side of the piston and closing the valve m. A decrease of pressure in the hydraulic system raises the valve h, opens the upper side of the piston j to exhaust, and opens the valve m. An excessive decrease of pressure, due to the breakage of a pipe &c., raises the valve h farther, closing the upper side of the piston j. Leakage of steam past the piston j closes the valve m. To pump up the pressure initially, the lever a is locked in the central position shown by a tumbler catch e.

Title: Improvements in centrifugal guns
IPC: F41B3/04
Filed: 1929-01-28
Abstract: 323,665. Powell, B. F. S. Baden-. Jan. 28, 1929. Centrifugal guns. -Single and doublebarrelled guns are provided with means for releasing the projectiles in the desired line of projection at the instant when the centrifugal force has attained the necessary value. As shown in vertical section in Fig. 1, the free end 6 of a leaf spring 5 projects into the barret 2 and is provided with a projection 9 which rides on the fixed releasecontrolling cam 11. When the gun revolves, the projectiles 8 tend to deflect the spring 5 and when the speed of revolution reaches a certain limit the resistance of the spring is overcome and the pin 9 is depressed into the recess 12 in the cam to release a projectile. Guns with two barrels are provided with a rockably mounted guide 40, Fig. 5, pivoted on a pin 42. The release cam 46 in this case is provided with two slots diametrically opposite each other. On the release of the projectile 45, the guide rocks about its pin and the next projectile is guided into position for firing from the opposite barrel. In one modification of the single-barrelled gun, a gravity or spring- operated two-armed pivoted lever has one arm projecting into the barrel and thus arresting the projectile and the other arm bearing against a fixed annular flange. A slot in this flange permits the release of the projectile when the centrifugal force is sufficient to overcome the weight of the lever or the resistance of the spring. In a further modification a spring-operated multi-armed catch is used. Each arm in turn serves to arrest a projectile. On firing, the catch rotates and the next arm comes into position in the barrel to arrest the next projectile. The release device is similar to that of the two-armed lever. Specification 272,342 is referred to.
