US Patent:

46018212, Jul 22, 1986

Filed:

Jun 10, 1983

Appl. No.:

6/503360

Inventors:

Robert M. Sherman - Granada Hills CA
Charles O. Fuerst - Simi Valley CA

Assignee:

Aquaria, Inc. - Chatsworth CA

International Classification:

E04H 316

US Classification:

210169

Abstract:

An aquarium filter of the free standing, nesting type is provided with an improved magnetic coupling system to couple a drive motor to the impeller which pumps water through the filter. A ring-shaped magnet is secured to the motor shaft and a second magnet coupled to the impeller and carried within the filter housing is inserted into the space inside the first magnet. The magnets are maintained coplanar and the rotation of the motor is coupled to the pump impeller of the filter in a very efficient fashion.

Appl. No.:

7/215655

International Classification:

A63F 922
A63F 924

US Classification:

273439

Abstract:

This invention involves a system of communicating information using audio signals. In one embodiment, the information is encoded in touch tones on the sound track of a television game show. The information relates to the action of the show, and is broadcast in-band with the audio portion of the show. The show, and thus the information encoded in its audio portion, is received by an ordinary home television. A device for playing a game "listens" to the television speaker and decodes the information. The device allows home viewers to play a game based on the action of the show. The touchtones are substantially indiscernible to humans because they are quieter than most of the audio portion of the show, they are very brief, and they are masked by the show's usual sound effects.

International Classification:

G21F 902

US Classification:

422159

Abstract:

An improved method and apparatus for storing isotopes of hydrogen (especially tritium) are provided. The hydrogen gas(es) is (are) stored as hydrides of material (for example uranium) within boreholes in a block of copper. The mass of the block is critically important to the operation, as is the selection of copper, because no cooling pipes are used. Because no cooling pipes are used, there can be no failure due to cooling pipes. And because copper is used instead of stainless steel, a significantly higher temperature can be reached before the eutectic formation of uranium with copper occurs, (the eutectic of uranium with the iron in stainless steel forming at a significantly lower temperature).

Appl. No.:

5/937258

Inventors:

Robert Sherman - Los Angeles CA

International Classification:

H05B 3702

US Classification:

323322

Abstract:

There is disclosed herein a method and apparatus for controlling the power dissipation in a load particularly suitable for use as a dimmer control for lighting circuits. Selected half cycles are applied to a load, such as an incandescent lamp. The number and sequence of the half cycles applied to the load are selected by logic circuitry which, according to the setting of a dimmer control, determines how many complete half cycles out of the total available to apply to the load. Zero crossing switching is used.

US Classification:

422159

Abstract:

A system of four cryogenic fractional distillation columns interlinked with two equilibrators for separating a DT and hydrogen feed stream into four product streams, consisting of a stream of high purity D. sub. 2, DT, T. sub. 2, and a tritium-free stream of HD for waste disposal.

Inventors:

Robert M. Sherman - Granada Hills CA

Assignee:

Aquaria, Inc. - Chatsworth CA

International Classification:

B01D 2506

US Classification:

210282

Abstract:

A filter cartridge for use with liquids or gases which includes a back structure having a plurality of channels formed in it and filtration granules contained within the channels. Each of the channels includes a plurality of holes to enable water to pass through the back structure. A filter element is secured to the front of the back structure to cover the channels. The provision of the channels enables a uniform distribution of filtration granules to be maintained throughout the filter cartridge.

International Classification:

B01D 35027

US Classification:

210169

Abstract:

An aquarium filter is disclosed that provides an overflow window for indicating a blocked filter cartridge. The filter cartridge extends across the full width of the filter box and includes an overflow weir, or lip. The overflow weir forms part of the filter structure and controls the flow of water when the filter cartridge is blocked. Since the filter cartridge extends across the width of the filter box, the size of the filter for a given flow rate is reduced. The filter provides the feature of overflow indication in a more compact and efficient structure than otherwise possible.
