A perfume compsn. contains a cyclopenta(a)naphthalene deriv. of formula (I) (where R1 is Me or Et; and either R2 is H and R3 is Me, or R2 is Me and R3 is H). In prepn. of (I), tetralin is reacted with isoprene to give a mixt. of isomers of dimethylcyclopenta(a)naphthalene deriv., which is Friedel-Crafts acylated and the isomers sepd.

The bung comprises a closure (115) threaded into the filler stub (107) of the barrel. It is removed, and refitted using a self centering jig which is servo driven. The automatic handling turned the barrel to align with the drive and an elastic coupling (42) ensures that the grip head (140) locates accurately in the closure. The filler stub is shaped to guide the flanged head of the handler accurat...

PURPOSE:To control two transistors so that the voltage between the emitter and the collector of one transistor may be equal to that of the other one even if there is a small difference in performance characteristic between the two transistors by connecting a constant-current control circuit between the stages of the two transistors and by connecting a circuit to hold a voltage between the emitter ...

PURPOSE:To obtain a heat generating method which is the same as a conventional method by using hydrogen which is extremely cheaper than heavy hydrogen by a method wherein heat is generated by applying potential gradient between both surfaces of a plate shaped body, for which one surface of a hydrogen occlusion plate is covered with a thin film, the hydrogen atom diffusion constant of which is smal...

PURPOSE:To simplify the control rod replacing works and shorten the time for operation by lessening the outside dia. of the lower part of control rod, locating a handle for uncoupling the control rod over a metal piece to support the fuel, and furnishing a means to uncouple the control rod. CONSTITUTION:The outside dia. of the lower part 6a of a control rod is lessened so that the rod 6 can pass a...

A semiconductor pressure sensor device that can improve the measuring accuracy without providing a silicon base in attaching a semiconductor pressure sensor chip to a lead frame, and a method of manufacturing thereof is disclosed. The semiconductor pressure sensor device includes a die-bond adhesive 10 formed of a resilient material for fixing a semiconductor pressure sensor chip 50 to a lead fram...

The semiconducting pressure transducer includes a pressure detection chip (2A) with a membrane (5) for converting pressure into mechanical tension, a strain meter for converting the tension into an electrical signal and an integrated circuit for amplifying the output signal and performing temp. compensation. The chip and its base (6A) are enclosed and encapsulated in a housing (17) with an opening...

The stacked sheets are supported on two parallel transport belts looped over transport rollers (1). Each roller has two supports comprising elastic belts (9) inside grooved supports formed between fixed (6) and axially movable (6') rollers. The axial movement spreads the elastic belts and effectively alters the dia. of the rollers. A feedback control system adjusts the roller dia. to keep the stac...

The invention relates to a device for extruding rubber blends and rubber-like materials, consisting of a screw extruder and an injection head shaping the extrudate in a strand-shaped manner. The object of the invention is to provide an extruder/gear pump combination suitable for processing rubber blends. The invention consists in that in the device for extruding rubber materials a gear pump is dis...

Fluid streams containing hydrogen sulfide from a steam tubine or from a sour gas stream are contacted with an aqueous solution of a polyvalent metal chelate and a bisulfite whereby the hydrogen sulfide is converted to free sulfur and then to soluble sulfur compounds. The metal chelate is reduced to a lower oxidation state metal chelate and reduced metal chelate is subsequently oxidized with air ba...

PURPOSE:To enhance easiness in inserting a control rod, secure the water zone, simplify the shuffling procedures for fuel aggregate, and provide possibility of enlarging the fuel aggregate by furnishing a cruciform cylindrical arrangement surrounding a control rod. CONSTITUTION:A cruciform cylindrical arrangement 2 surrounding a control rod 3 is provided in a lattice-shaped space formed by a fuel ...

A process of hot pressing of materials to form articles or compacts is characterized by the steps: (A) providing a compactable particulate mixture; (B) uniaxially pressing the particles without heating to provide article or compact (22); (C) placing at least one article or compact (22) in an open pan (31) having an insertable frame (32) with edge surfaces (34) that are not significantly pressure d...

In a network termination connected to an exchanger and a plurality of terminal adaptors and enabling relief of call congestion in an exchanger, the network termination includes: a reception port (111) for receiving a reduction rate indicated by a congestion information area in a SDH frame input from the exchanger (20); a SDH frame transmission unit (113) for transferring the SDH frame including a ...
