Abstract: APPAREIL DE PRATIQUE POUR AMELIORER LA ION DES LANCERS AU HOCKEY Un appareil de pratique pour améliorer la précision des lancers au hockey. Cet appareil comprend un but destiné à être substitué à un but de type conventionnel et fixé de la même façon que ce dernier à la surface d'une patinoire à proximité de l'extrémité de celle-ci. Le but de substitution comprend deux poteaux et une barre horizontale de dimension réglementaire définissant un cadre, ainsi qu'un filet fixé en arrière du cadre. Au moins deux cibles verticales sont fixées aux poteaux et à la barre horizontale de façon à s'étendre à l'intérieur du cadre du but. De la même façon, des lampes sont fixées aux poteaux ou à la barre horizontale de façon à se trouver à l'intérieur du cadre du but et à indiquer à un joueur voulant pratiquer ses lancers laquelle des cibles il doit viser et essayer de toucher. Un circuit électronique de contrôle est prévu pour allumer les lampes les une après les autres dans n'importe quel ordre et même répétitivement à une vitesse donnée pour obliger le joueur à viser l'une ou l'autre des cibles. Ce circuit électronique peut être disposé dans une boîte portative et inclure un système de signalisation sonore relié électriquement à un jeu de contacts associé à chacune des cibles de façon à fournir un signal sonore aux joueurs pratiquant leurs lancers à chaque fois qu'une rondelle lancée a atteint la cible dont la lumière est allumée.

Abstract: Abstract of Disclosure A supply apparatus for the enrichment of aquarium water with CO2 is described.  In order to increase the diffusion surface, several containers which are open at their bases are arranged above one another along a gas inlet pipe, the whole being assembled substantially vertically.  The CO2 gas intro-duced into the bottom container displaces the water, and subsequently fills the above described containers in a cascade in a type of pneumatic tank.  The thus increased contact surface of CO2/water results in rapid adjustment to the desired higher CO2 concentration.

Abstract: Abstract of the Disclosure A mowing rotary sawtoothed cutter adapted to be attached to a mower for mowing or cutting grass, shrubs or trees, which comprises a thin disk having a central hole, and a suitable number of triangular small cutting blades disposed around the outer periphery of the disk and having cutting edges extending from the apex of the triangle along the both lateral edges thereof, half of the small cutting blades facing in one direction and the residual half of the small cutting blades facing in the other direction.  In a preferred embodiment, the cutter includes a plurality of large cutting blades in the form of a rectangle or the like having cutting edges on the opposite lateral edges thereof, and a series of the small cutting blades facing one direction and a series of the small cutting blades facing the other direction are disposed in opposed relation to each other between the large cutting blades.  The cutter of the invention has the feature that at the same time as the cutting edges on one side perform mowing or cutting, the cutting edges on the other side are sharpened by hard substances scattered around or sticking to the rhizomes of grass and shrubs, thereby allowing turned-over use of the cutter several times, thus the use-life without manual sharpening is greater than 10 times that of a conventional cutter.

Abstract: Abstract (in conjunction with Figure 1) When piece goods are transported on continuous con-veyors, it is often impossible to prevent some of the piece goods from having to be stopped momentarily when the con-veyor continues the run.  In order, very substantially, to prevent the resulting mechanical stresses on the piece goods, especially the frictional stresses, caused by the continuous conveyor which continues to run, the invention proposes a continuous conveyor of simple construction with only a single tension member (sheathed chain 10), on which freely rotat-able pile-up rollers (12, 39) are arranged on both sides 25 a carrying member.

Abstract: PYROTECHNIC CURRENT INTERRUPTER                       ABSTRACT        Apparatus is provided for automatically interrupting current in an electrical circuit before the first current peak which occurs after an excess current condition develops.  The apparatus includes a main conductor in the current path which passes the current under normal operating conditions, and pyrotechnic charge means associated with the conductor at several spaced locations which segments the conductor when it is ignited.  The charge means is ignited by a fuse link which senses the current and provides a rapid thermal response to excess current conditions, generating sufficient heat to ignite the charge means within a short period of time.  A current limiting fuse element may be connected in parallel with the conductor for operation at higher voltages, if needed, and the entire apparatus, including the resistive sensing means, may be contained in a single housing.

Abstract: ABSTRACT OF THE DISCLOSURE A compact lightweight engine or pump is constructed having a H-shaped piston, usually double acting. Each end of the piston has extending surfaces which form two moving sidewalls which act with two case sidewalls and a block-shaped head protrusion to define a working chamber with the appropriate top surface of the piston which moves to extract or add energy to the working chamber.  Energy is transferred between the piston and a crankshaft by means of a slide block on the crankshaft and the inner surfaces of a pair of parallel walls forming the center of the "H" of the piston, whose opposite surfaces form the piston top surfaces.  Through the use of suitable cams and valves, 4-cycle, 2-cylinder equivalent engines can be produced.  With suitable porting, baffles, and/or auxillary compression means, 2-cycle engines can also be produced as well as air pumps.  The planar walls of the devices maximize displacement while the planar design reduces mechanical stress allowing coatings of heat resistant materials such as ceramic for thermal protection rather than extensive cooling systems.

Abstract: STUFFING METHOD AND APPARATUS                          ABSTRACT           An improved high speed stuffing machine for forming links such as frankfurters.  The permanent stuffing horn of a conventional link stuffing machine is dispensed with, and apparatus is provided for utilizing highly compacted shirred casing carried directly on a disposable core, wherein the core serves as a rotatable stuffing horn.  A roller chuck is provided for engaging and rotating the cored casing article for purposes of linking, and resisting the thrust of the core due to emulsion flow while providing an emulsion seal between the casing article and chuck to prevent backflow of emulsion.  The aft end of the core is received in a quick connect emulsion discharge which provides a bearing surface and a rotating emulsion seal to allow the core to rotate while the discharge remains stationary.  The cored high density casing article allows the casing length to be increased by an integral multiple over conventional practice, which results in significant economies in the high speed production of linked sausages.
