Title: Variably damped passive tank stabilizer
IPC: G05D1/08
Filed: 1968-05-08
Abstract: A passive tank roll stabilization system for ships comprises an elongated tank 10, a body of free surface liquid 18 partially filling the tank to a level at which the tank imparts to the ship 16 an oscillating, timed stabilizing moment near the natural frequency of the ship, a closure assembly 20 located within the tank and spaced from the ends thereof to selectively isolate and permit liquid communication along the liquid path within the tank, and sensing and control means 72, 76 for sensing the roll frequency of the ship and completely closing the closure assembly to de-activate the tank when the ship rolls at a first frequency away from its natural frequency and at which the tank liquid would de-stabilize the ship so that the ship rolls at an amplitude primarily dependent upon the ship's static stability. The closure assembly may be in the form of sliding doors or rotating horizontal or vertical flaps. In the embodiment described the assembly consists of a door 24 supported for rotation about a vertical shaft 26 between upstanding plates 22.

Title: Process for preparing glycidyl esters of polycarboxylic acids
IPC: C07D301/30
Filed: 1968-06-26
Abstract: Glycidyl esters of polycarboxylic acids which are free from other epoxide-reactive groups, are prepared by reacting the acid and sufficient of an epihalohydrin to provide 2 mols. epihalohydrin per mol. carboxylic group, in the presence of a tertiary amine, a tertiary amine salt or a quaternary ammonium compound as catalyst, at 150-200 F. until the acid is substantially completely esterified and dehydrohalogenating the halohydrin ester by slow addition of an alkali metal hydroxide at 90-130 F. under a pressure low enough to ensure distillation of the water from the reactants. It is preferred to use 5-10 mols. of, e.g., epichlorohydrin, per mol. acid group and to employ an aqueous solution of the hydroxide in the second step. The glycidyl ester may be recovered by adding sufficient water to dissolve the halide salt by-product and distilling the epihalohydrin solution of the ester which forms the non- aqueous layer. Examples relate to the preparation of the glycidyl esters of adipic, isophthalic, terephthalic, azelaic and a C 18 dimer acid.

IPC: G21F7/047
Filed: 1969-05-17
Abstract: A glove box 1, which may be surrounded by shielding 3, has a transfer chamber 9 sealed at its two ends by doors 12, 13. Scavenging air is drawn through the glove box by suction applied at a pipe 26 whereby the interior 2 of the glove box is maintained at sub-atmospheric pressure.

Title: Method and apparatus for mixing two gas currents
IPC: B01F23/10
Filed: 1978-06-30
Abstract: A method and apparatus for mixing a first relatively cool gas current and a second relatively hot gas current in a manner such that the resulting gas current has a relatively uniform temperature immediately subsequent to the point of mixing. The first gas current is separated into first and second partial gas currents, the first partial gas current being directed to a conduit which branches from the conduit in which the second partial gas current is directed. The first partial gas current is directed at a relatively high velocity into a central nozzle in fluid communication with the second gas current while the second partial gas current is directed into a ring nozzle which also is in fluid communication with the second gas current and which concentrically surrounds the central nozzle. The flow of the first gas current is regulated by throttling the second partial gas current while maintaining the flow of the first partial gas current. The method and apparatus has particular application in the regulation of the inlet temperature to a heat exchanger of a cooling gas current in a dry cooling plant for hot bulk materials, such as coke.

Patent ES-8200536-A1 (ES)
Title: Decentralized call metering
IPC: H04M15/30
Filed: 1980-04-14
Abstract: In a telephone exchange system it is often required to be able to assess call charges at a decentralized location, such as at a calling subscriber's instrument, e.g. a coin box telephone. Such an arrangement includes a reference number memory (7) which holds codes for all charging zones accessible to a subscriber using that telephone instrument. When a wanted number is dialled, it is placed in a register (2) and its prefix code digits compared by a comparator (3) with the stored codes, which are read out cyclically by addressing means 4, 5. When the code for the wanted number is read out, as indicated by the comparator (3) the latter stops the read out, the point in the read-out cycle at which comparison is achieved is indicated by the setting of a counter (4). The setting of this counter causes the selection of a generator (one of Z1, Z2 ... Zn), which supplies meter pulses appropriate to the wanted line's zone and thus its charging rate, to an evaluator 11.
