Title: Ski boot having a thigh securing upper shaft
Inventor: HEUVEL JOHAN G F
IPC: A43B5/04
Filed: 1995-03-24
Granted: 2004-05-11
Abstract: Conventional ski boots limit the area of bodily contact between the skier and his-her ski boots to a foot and ankle securing lower boot portion and a leg and ankle securing shaft.      In the ski boot according to this invention, the area of bodily contact between the skier and his-her ski boot comprises: a foot and ankle securing lower boot portion, a leg and ankle securing resiliently positioned leg securing shaft, a hinged thigh securing upper shaft, and a detachable handle bar for manual engagement by the skier. The ski boot comprises means to control and limit lateral tibial rotational movement. reducing the risk of spiral fractures.      In one embodiment. the upper shaft is urged upwardly, reducing muscular effort to maintain the flexed position and reducing stress onto the knee joint.      The boot is provided with a position for storage and handling, reducing overall size when not in use.

Abstract: A container comprising a base, a pair of side walls, and first and second end walls. The pair of side walls are releasably connectable to the base by slidable movement from a first position to an intermediate position and then to a final position. The side walls are releasably connectable to the first and second end walls. The first end wall is releasably connectable to the base after the first end wall has been connected to the side walls when the side walls are in their intermediate position by slidable movement of the pair of side walls and the first end wall as a unit over the base to the final position of the side walls. After connection of the first end wall and side walls to the base, the second end wall is releasably connected to the side walls to complete the container. Interlocking three of the four walls to the base provides a container that is very strong and damage resistant. The container is also quick and simple to assemble and requires no tools.

Abstract: A pre-fillable hypodermic syringe is provided. The hypodermic syringe includes a syringe barrel having opposed proximal and distal ends and a drug-receiving chamber therebetween. The distal end of the syringe receives a needle cannula that is sealingly and protectively covered by a cap. The proximal end of the syringe is sealed by a stopper assembly. The stopper assembly includes a distal stopper that is positioned adjacent the drug pre-filled into the syringe barrel. The distal stopper is formed to exhibit acceptably low sliding forces without the presence of lubricants deleterious to the drug. The stopper assembly further includes a proximal stopper formed from a material that exhibits acceptable microbiological sealing. Because the proximal stopper is separated from the drug by the distal stopper the proximal stopper may be treated with any convenient lubricant, such as silicone oil. The distal stopper functions as a barrier between the drug and the lubricant such as silicone oil that is on or near the proximal stopper. The proximal stopper, on the other hand, provides the required microbiological sealing.

Abstract: A wrench selector provides for the quick and accurate checking of the dimension of a nut or bolt across the flats thereof, in order to determine the corresponding size of the wrench or socket required for use therewith. The selector incorporates two jaws, with the first jaw extending from an elongated scale and the opposite jaw extending from a body sleeve through which the scale slides.  The scale includes several rows of dimensional numbers thereon, with each of the numbers corresponding to a distance between the two jaws.   The numbers are staggered diagonally across the face of the scale, in order to spread them for greater legibility.  The body or sleeve  includes  a  set  of  windows  spaced  laterally thereacross, which in combination with the diagonal array of dimensional numbers, results in only a single one of the dimensional numbers being exactly aligned within a corresponding one of the windows for any measurement. The scale numbers correspond with the standard sizes of nuts and bolts used in industry, and the selector may include inch and fractional inch measurements on one side and metric measurements on the opposite  side.   The selector may be formed of various durable or disposable materials as desired, and may be made sufficiently small so as to fit within a conventional shirt pocket, in order to be readily available to the user at all times.

Abstract: An active current injection device (117) generates and injects fundamental and non-fundamental frequency current components onto an AC power line (111). A current pump control circuit (132) receives an input signal which is representative of the power line voltage and generates a control signal which is used to generate a fundamental frequency current component which lags the line voltage by approximately 90 degrees.  This fundamental frequency current component is transmitted through an impedance (131) to the line (111), thereby causing a fundamental frequency voltage drop across the impedance (131). A damping control circuit (116/176) receives an input signal representative of the line voltage and generates as output signal having first and second components proportional to the line voltage and the line voltage rate of change, respectively. The output signal is used to generate an electronic load current component which loads non-fundamental frequency components of the line voltage.

Abstract: A fuel-fired, forced draft, down-fired water heater is provided with an improved combustion product flow path that permits the heater to operate with improved fuel efficiency, lowered CO and NOx emissions, and an improved water heat input distribution along the vertical length of the heater.  The water heater includes a vertically oriented tank with a vent plenum structure formed at the top end of the tank interior and having an outlet passage connectable to an external combustion product vent pipe.  A centrally positioned submerged vertical burner tube extends downwardly from the vent plenum and has an open lower end extending into a submerged turn bowl disposed at the bottom end of the tank interior.  Extending upwardly from the turn bowl within the tank interior, and symmetrically arranged about the centrally disposed burner tube, are a plurality of vertical flue tubes that communicate the interiors of the turn bowl and the vent plenum.  A suitable fuel burner is disposed within the burner tube and is supplied with a throughflow of a pressurized fuel/air mixture which is ignited to create a downwardly directed flame and associated hot combustion products.  During operation of the water heater, the hot combustion products are sequentially flowed downwardly through the burner tube into the submerged turn bowl, upwardly through the flue tubes into the vent plenum, and then outwardly through the vent plenum outlet passage.

Abstract: On décrit un système de priorité destiné aux feux de signalisation, ainsi qu'un procédé de fonctionnement de celui-ci, dans lesquels on utilise des mesures du système mondial de radiorepérage (GPS) différentiel pour détecter de manière exacte la position, la vitesse et la direction d'un véhicule de service ou d'un véhicule prioritaire s'approchant d'une intersection régulée. Ce système comporte un récepteur GPS de référence, destiné à calculer des corrections des mesures GPS, ainsi qu'un récepteur GPS placé dans chaque véhicule et qui émet, par radio, ses mesures GPS en direction d'un récepteur situé au niveau de ladite intersection. A l'aide des mesures corrigées de position, de vitesse et de direction et conjointement avec des données précédemment enregistrées et déterminant des itinéraires d'approche de l'intersection, un ordinateur, également placé au niveau de l'intersection, détermine le temps optimum pour commuter sur mode priorité un régulateur de signalisation, afin de permettre le passage sans danger du véhicule. On peut introduire des corrections de mesures GPS dans un ordinateur de véhicule ou dans celui situé au niveau de l'intersection. D'autres modes de fonctionnement du système comprennent un mode surveillance automatique, grâce auquel le récepteur GPS de référence détermine sa position réelle en établissant une moyenne des mesures de positions sur une période d'un jour ou deux, ainsi qu'un mode apprentissage, grâce auquel l'ordinateur de l'intersection apprend des itinéraires inhabituels d'approche de l'intersection, lorsque le véhicule coupe à travers les itinéraires d'approche et émet des mesures de position et de vitesse.
