Title: Arrangement for suppressing overshoot caused by level regulation in carrier-frequency systems
IPC: H04B3/12
Filed: 1972-10-17
Abstract: This relates to level regulation in a carrier frequency system with a plurality of repeaters in tandem.

Title: Mechanical power amplifier, in particular for a machine vise
IPC: F16H25/18
Filed: 1976-04-19
Abstract: A mechanical power amplifier for a vise having housing means and a primary member and a secondary member mounted therein. At least the primary member is movable in the housing and transmits a force to force amplifying and transmitting structure also mounted in the housing to effect both an amplification of the force transmitted thereto as well as a transfer of the force from the primary member to a force transmitting member. The force amplifying and transmitting structure includes a pair of bell-crank levers arranged in a mirror-image manner relative to the center axis of the housing.

The wedge surface engages a cam surface on the primary member and is movable laterally in response to a movement of the primary member. A pair of laterally spaced rollers are positioned on opposite sides of the center axis of the housing and engage the short lever arm and an abutment surface on the secondary member. Arcuate surfaces are provided on the side of each of the short lever arms remote from the rollers. As a result, the force transmitting member is moved relative to the housing in response to a lateral movement of the arcuate surface on the bell-crank levers caused by a movement of the primary member and the cam surface relative to the long lever arm so that each of the bell-crank levers are rocked about an axis defined by the location of engagement between the short lever arm and the roller.

Title: Regeneration method for gravity-flowing deactivated catalyst particles
IPC: C10G35/06
Filed: 1978-06-12
Abstract: A continuous method for regenerating deactivated catalyst particles in a regeneration zone through which the particles are downwardly movable by way of gravity-flow. Particles are initially introduced into an upper carbon-burning/halogenation zone wherein they are contacted, in a first section, with a first air stream and a first mixture of steam and a halogen, or halogen-containing compound. Partially regenerated/reconditioned particles are then contacted, in a lower second section, with a second air stream and second mixture of steam and halogen. From this two-sectioned, carbon-burning/halogenation zone, the catalyst particles flow via gravity into a drying zone wherein they are contacted by a substantially dry air stream.

Title: Apparatus and process for recovering nuclear fuel from scrap material
IPC: B01D11/04
Filed: 1978-07-11
Abstract: A process for recovering compounds of enriched nuclear fuel from scrap materials is disclosed. The process yields an acid solution with the nuclear fuel dissolved therein. Except for spent filter media, the scrap materials are calcined to produce an oxidized material, which is reduced to a particulate material and leached in an acid bath that contains some recycled acid to yield an acid solution of the nuclear fuel material. The scrap materials comprised of spent filter media are mulched and contacted with the acid solution. The insoluble materials are separated from the acid solution, and at least a portion of the acid solution is recycled to the leaching step, while the remainder of the acid solution is collected for subsequent treatment to recover the dissolved nuclear fuel material. Apparatus for performing the foregoing process is also disclosed.

Patent ES-474330-A1 (ES)
Title: Controlled flow cooling system for low weight reciprocating engine
IPC: F02F7/00
Filed: 1978-10-18
Abstract: A light metal die-cast head and cast iron block employ a low volume cooling system which cooperates with the differing thermal conductivity properties of said head and block. The cooling concept eliminates the conventional intricate water jacket and replaces it with continuous grooves which wrap hemi-cylindrically about each combustion cylinder in a thinly spaced relation. The grooves are exposed along their length at the deck surface of either the head or block. The total fluid mass in the system is reduced to as little as 1/5. There are two such grooves in the block which (a) extend from one end thereof to the opposite end, (b) are on opposed sides of the cylinder galleys and (c) have substantially no transverse flow in order to promote laminar or controlled flow. There is a critically located straight drilled passage along with two such grooves in the head, the combination of which is restricted in throat area when compared to the throat area of the grooves in the block this results in a high velocity flow in the head and a low velocity flow in the block when they are connected in series flow relation. The straight longitudinally drilled passage (which may include one or more of such passages) is located in the head separating the exhaust and metal valve guides the passage has a throat area equal to or less than the throat area of either of the grooves in the head. Heat extraction is more easily and flexibly programmed to achieve not only a more uniform wall temperature throughout the head and block, but permit a desirably slightly higher average wall temperature than conventional light metal heads for improvement in fuel economy and thermal efficiency.
