Patent CA-1326744-C (CA)
Title: Toothbrush
Inventor: KLINKHAMMER RONALD W
IPC: A46B1/00
Filed: 1989-08-03
Granted: 1994-02-08
Abstract: TOOTHBRUSH                  Abstract The brush has sets of relatively reciprocably displaceable bristle which are straddled about a row of teeth, transverse thereof, and applied to the opposing faces of the teeth by means of a pair of paddle-headed  tweezer-like rods which are semi-rigid and discrete from one another, but hingedly interconnected with one another so that they can be held in unison as a handle while being rotated in relation to one another about an axis extending substantially parallel to the mutually adjacent sides thereof.  As they are applied to the faces of the teeth, the bristle may also be translated along the length of the row; and is so, the bristle may be equipped with a pair of picks, which are used to locate the gum lines of the teeth and steer the bristle while raking the gum lines themselves. Moreover, in such a case, the picks may have thin flanges extending relatively toward one another, to provide fillet-like gussets with which to stab-ilize the picks against splay when they are traced along the gum lines.  The brush lends itself to being packaged and shelved in compact form, and if desired as a disposable brush, that is, as one to be put to use a time or two and then thrown away. For example, it can be fabricated as a thin, flat item which has a cross hinge so that it can be reentrantly folded onto itself, longitudinally thereof, for compactness.

Title: Process for producing pure sodium polysulfides directly from higher sodium polysulphides and sodium
Inventor: BITTNER FRIEDRICH
IPC: C01B17/34
Filed: 1989-09-15
Granted: 1993-05-25
Abstract: ABSTRACT OF THE DISCLOSURE           The present invention describes processes for the production of lower sodium polysulfides, such as sodium disulfide, from higher sodium polysufides and sodium.  To this end, one either converts a prepared molten sodium polysulfide with sodium in a stoichiometric ratio that corresponds to the desired product with vigourous agitation in a protective gas, or under the same conditions dopes the higher polysulfide and the sodium into a prepared molten polysulfide, either in alternation or simultaneously.  In either case, the doping of the sodium is so adjusted that the reaction mixture remains stirrable, and is stirred until the desired composition of the product is obtained.

Title: Induction-based assistive listening system
Inventor: LEDERMAN NORMAN
IPC: H04R25/00
Filed: 1989-09-20
Granted: 1992-05-26
Abstract: ABSTRACT OF THE DISCLOSURE   A multiple-loop magnetic induction system for improving communication with the hearing-impaired or to people in general who wish to listen privately to speech or music while being in the company of others or at a public location. The invention uses a particular grid made up of several electrical conductors as a means of generating an audio-frequency magnetic field which in turn couples to the telephone coils already present in most hearing aid units. The audio-frequency magnetic field is correlated to sound waveforms -- speech, music, etc. -- which is to be communicated. The grid configuration is selected so as to produce an end signal which is substantially independent of the location and the orientation of the hearing aid device within the area of the grid and which falls off precipitously outside of the region defined by the grid. The conductors which make up the grid configuration are enveloped in a flexible, lightweight matting which can be unrolled in the area to be addressed.

Abstract: Method and aparatus for production of a gas from a comminuted biological waste material, such as straw, in which method the comminuted material is introduced into a reactor through a gastight lock possibly with an addition of steam and distributed into a bed of catalytic bodies, which are moving in such a way that the material during the gasification is flowing along a predetermined path as the produced gas and the residual material are removed through the bottom of said bed. In order to produce a gas of high calorific value and without tar and to prevent the surfaces for heat transmission from tar deposits, and to prevent formation of residual material from the gas production that contains substantial amounts of compositions, which are unacceptable to the environment, the method is characterized in that the bed is heated indirectly, and that the agitation of the catalytic bodies is provided by such a vibration of the bed that the material is conveyed downwards through the bed, the filler bodies being ceramic carriers for a catalytically acting heavy metal.

Abstract: A multi-purpose tracheal tube for use with high frequency ventilation. The tube is an endotracheal tube including up to three lumens, in addition to the primary lumen, which serve various functions to provide versatility in the treatment of patients. In cuffed tubes one of the lumens is used for inflating the cuff once the tube has been placed in the desired position in the trachea of the patient. Another lumen, referred to as the "insufflation lumen", is used to deliver oxygen or other gases by constant insufflation, intermittent jet ventilation or high frequency ventilation. The third lumen, when incorporated, is employed for monitoring and irrigation. The distal opening of the irrigation or monitoring lumen is located just inside the distal tip of the tube while the insufflation lumen opening is located rearwardly toward the proximal end of the tube relative to the irrigation or monitoring lumen opening.

Abstract: In frames consisting of sheet-metal sections (1) which have a bending edge at the edge with the tread plane because one leg (2) of the frame is bent round into the tread plane, this edge cannot be made sharp. Thus, when the panels are laid against one another, there is a small gap which, especially where thin hard floor coverings are concerned, can lead to a break of the floor covering at this point under a load exerted at a particular point. The sharp edge can be obtained, on the one hand, by designing the leg (2) as a sheet-metal part (5) bent back on itself, the free end of the sheet-metal part (5) coming to rest on the panel edge. Alternatively, it can be achieved in that a bead (9) formed in the sheet-metal section (7) in the vicinity of the respective panel edge is evened off in a tool in such a way that it forms as a result of the creep of the sheet-metal material. In the finished floor panel, the frame is filled with flowable hardening material. <IMAGE>
