Abstract: An artificial aquarium plant which includes an anchor in the shape of a narrow, elongated trough having a generally V-shaped cross section. The ends of the anchor are diverging downwardly to form scoops at the opposing ends. Transverse connecting walls define storage cells therebetween to receive the anchoring material, such as sand, for retaining the anchor at the bottom of an aquarium tank. A hollow tubular post provided in the anchor includes a restraining shoulder in its hollow portion. The plant member includes a bifurcated stem which can be inserted into the hollow post, and a ledge or lip section on the stem which engages the restraining shoulder to prevent removal of the plant member from the anchor. A package is designed to retain the artificial aquarium plant where the anchor acts in such a manner as to avoid crushing of the plant member.

Abstract: A bottom aquarium filter for an aquarium tank which includes a container having an inlet compartment which can receive contaminated water from the tank, and a filtration compartment which converts the contaminated water into decontaminated water. The filtration compartment contains a mass of filtering material with a restraining plate positioned in the filtration compartment to restrain the filtering material within one section thereof while maintaining another section substantially free of such filtration material, thereby providing a flow chamber which couples the inlet compartment to the section containing the filtering material. An air diffuser, attached by tubing to an air compressor located outside the aquarium tank, provides a stream of air bubbles to lift water from the decontaminated water compartment through an air lift tube.

Abstract: A dental model trimmer having an easily replaceable abrasive surfaced member. The abrasive surfaced member is contained within a housing and is releasably coupled onto a back plate assembly which is driven by a drive motor. The housing includes a releasably coupled cover plate providing access to the abrasive surfaced member. An opening formed in the cover plate exposes a portion of the abrasive surface so that a dental model workpiece can be inserted into the opening against the abrasive surface to permit work on the dental model workpiece. A tilting work table beneath the opening supports the workpiece during the operation. A stream of water is directed through the front cover onto the abrasive surface and is redirected against this surface by means of baffles positioned inside the cover plate. The opening includes a beveled boundary and an inwardly directed lip permitting angular manipulation of the workpiece, better visibility of the workpiece and maximum safety.

A lining surrounding a through-bore in the wear part may be cast therewith. The wear part is preferably clamped in a supporting frame.

Abstract: A large screen television system comprising two sections which are interconnected at their adjacent ends to define a substantially L-shaped housing configuration. The lower section is an elongated container with a television set supported near the bottom of the container having a lens assembly positioned on top of the television set. At the remote end of the upper section there is provided a rear projection screen. A reflective surface is angularly positioned at the interconnection between the two sections. A picture produced on the television screen is focused by the lens assembly to produce an image on the reflective surface. The image is then reflected from that surface and is projected onto the rear of the projection screen so that an enlarged image of the picture received by the television set may be viewed at a location in front of the screen.

Abstract: A micro-capsular material for use as a photographic reproducing medium includes a plurality of micro-capsules distributed over a given surface. Each of the capsules is formed with a mantle of light transmissive material. The mantles may be clear or colored and are advantageously transparent. The contents of each of the capsules includes a photoconductive material as well as a color progenitor or precursor material. Simultaneous exposure of the capsular material to light and high frequency electrical energy causes rupture of the capsule mantles and release of the capsular contents. When an image is focused by a lens onto the surface, selected ones of said capsules are ruptured to thereby result in a reproduction of the image. Dispersing micro-capsules having different color progenitor materials makes possible color photography when means are provided for selectively directing only those component of colored light onto the micro-capsules having corresponding color progenitor materials.

A groove formed between the inner and outer sections accommodates passage therethrough of the pump line cord during storage of the line cord within the inner section.

Abstract: A handle for a medical instrument having a handle portion. The handle portion is fabricated from metal, preferably stainless steel, and is provided with at least one annular channel disposed completely around the handle portion. An elastomer material, preferably silicone rubber, is molded on the handle portion to completely cover the handle portion, where the elastomer material extends into and fills the channel. The elastomer material provides pressure within the channel when the medical instrument is heated during steam sterilization thereof so that the elastomer material defines a seal within the channel to prevent moisture from passing between the covered handle portion and the elastomer material. Additionally, the handle portion may be provided with holes extending therethrough which are filled with the elastomer material to additionally secure the elastomer material to the handle portion.

Abstract: A procedure and installation for the manufacture of partial laced wiring harnesses in which each cable is pulled from an independent feeder and fed into a horizontal plane, then gripped at a forward free end. Each cable is then independently transported further in a constant stretch in an axial direction of the wiring harness to obtain a preselected length for each cable, where the cable is preferably arranged in the form of a loop and disposed in a transport installation. The front and rear portion of the preselected length of cable are gripped by members of the transport installation, and the forward free end is released. After cutting the cable to length, the cable is still gripped at the front and the rear portion thereof and is transported further horizontally at right angles to the axial direction of the cable ends. Then, at least one end area of the cable is bared and provided with a connector and thereafter provided with a casing.

Abstract: An apparatus for the treatment of powdery and granular substances, which provides for cooling or heating and/or spraying the substances with liquid or molten addition or treatment elements in a vessel rotationally symmetrical to its vertical axis. The substances to be treated are introduced into a vortex flow at the head of the vessel and then carried along by a substantially axially parallel, downward-moving gas stream and are conducted through a spraying zone in which the liquid or molten elements are sprayed thereon. This flow, after a movement undisturbed over a certain interval, strikes upon a counterflow rising from underneath, the velocity adjustment of which is determined by the sifting effect and/or the staying time. The gases, preferably air, enter the vessel in a tempered state in correspondence to the desired result of the process.
