Title: A device for breaking a hard material
Inventor: EDNEY BARRY E
IPC: B26F3/00
Filed: 1980-10-15
Granted: 1984-06-14
Abstract: A liquid jet cannon having a reciprocably movable piston device (6). The piston device is held in cocked position against the action of a gas pressure accumulator (19) by liquid pressure in a first chamber (15) until initiation of a power stroke. The power stroke is initiated by depressurization of a control chamber (16), whereby a valve (11) is moved to its open position so that a flow communication (39) is created between the first chamber (15) and a second chamber (17). The first chamber is thus rapidly depressurized so that the pressure in the gas pressure accumulator (19) drives the piston device (6) into a liquid chamber (14) to produce a liquid jet pulse for breakage of the hard material.

IPC: C07B61/00
Filed: 1981-02-13
Granted: 1984-01-26
Abstract: A process for the production of olefins from synthesis gas comprises a first synthesis stage in which a mixture of methanol and higher alcohols are formed from a synthesis gas comprising hydrogen and carbon monoxide. The catalyst for the first synthesis stage comprises the oxides of copper and zinc in intimate association with each other and a promoting compound selected from the group consisting of chromium, cerium, lanthanum, manganese, thorium, and an alkali metal. The materials from the first synthesis stage are separated into a gas phase and a liquid phase. Thereafter the methanol is separated from the higher alcohol fractions. The higher alcohols are then subjected to dehydration in a dehydration stage which comprises passing the higher alcohol fraction over an alkalized dehydration catalyst at a pressure in the range of 0.5-1 bar and a temperature in the range of 350 DEG -500 DEG  C. Thereafter the olefins produced by the dehydration of the higher alcohols are separated into the olefinic and non-olefinic materials. Preferred dehydration catalysts include alkalized aluminum oxide and alkalized calcium phosphate.

Title: Method of and circuit arrangement for supplying current to a two-wire telecommunications line
Inventor: CHEA RAMON CON WOO
IPC: H04B3/03
Filed: 1981-08-22
Granted: 1985-08-08
Abstract: The transverse and longitudinal termination impedances of a subscriber line interface circuit may be independently controlled. The equivalent termination impedance of a subscriber line/trunk appearing to the central office can be adusted upward or downward from a lower resistance value, with longitudnal balance being determined by the matching of feed resistors. The circuit is implementable as a monolithic integrated circuit having low power dissipation, improved power bandwidth requirements, and lower voltage breakdown requirements for integrated circuits; all resulting in an improved telephone line interface circuit. Voltage or current feedback to synthesize the proper ac transverse termination impedance from a known dc resistance, is utilized the feed resistors in a telephone line circuit. The transverse and the longitudinal termination impedance are determined by choice of feed resistance value. The independent control of transverse impedance is achieveable as a result of the feedback circuitry being nonresponsive to longitudinal signal.
