Title: Hinge for furniture
Inventor: BENEKE ULRICH
IPC: E05F1/12
Filed: 1994-09-22
Granted: 2003-12-30
Abstract: A furniture hinge has a housing (2) and a supporting part (3) with an articulated connection and closing and restraining device in the form of a flat spring (12) arranged within the housing (2). The flat spring (12) works in conjunction with a cam surface (10) during the opening movement of the hinge.  The flat spring (12) is arranged in the bottom (13) of the housing (2), more or less parallel to this bottom part, and its middle area is supported on a raised area (14) that is associated with the bottom (13) of the housing. As a result of this arrangement close to the bottom, the flat spring is very inconspicuous, and does not detract from the appearance of the furniture. The flat spring can be installed very easily and requires only a very simple basic structure for the hinge type, so that the flat spring can be used as required.

Abstract: L'invention consiste en un procédé d'isomérisation d'hydrocarbures aliphatiques linéaires dont le nombre d'atomes de carbone est supérieur à 6 pour en faire des hydrocarbures ramifiés présentant ainsi un meilleur indice d'octane. Le procédé consiste à faire passer l'hydrocarbure dilué dans l'hydrogène sur un catalyseur à basa d'oxycarbure de molybdène qui est obtenu soit à partir de carbure de molybdène que l'on soumet à une oxydation ménagée, soit à partir d'oxyde de molybdène MoO3 que l'on réduit par un hydrocarbure. L'avantage de l'invention par rapport aux catalyseurs de l'art antérieur est qu'il permet d'atteindre une sélectivité élevée en isomères ramifiés quel que soit le taux de conversion ce qui valorisa les coupes pétrolières n-heptane et n-octane.

Granted: 1997-03-25
Abstract: The disclosure involves a material handling machine, e.g., a crane, having a control circuit switch and a power limit switch.  Disclosed is a new weight assembly having first and second weights.  The control switch is maintained at a position by the first weight and the power switch is maintained at a position by the second weight which is positioned above the first weight.  The weights are telescoped to one another so that vertical weight alignment is assured as the crane hoist bottom block contacts and lifts the first weight.  If the bottom block continues its upward travel past a maximum desired elevation, the first weight (urged by the bottom block) lifts the second weight, permitting the power limit switch to trip and preventing the bottom block from continuing upward.  And the new assembly is ideal where the space available for limit switch weights is restricted.

Granted: 2000-10-03
Abstract: A hydro-thermo massaging tub and method of massage treatment  is  described  and  wherein  the  treatment  is performed by warm air jets distributed adjacent the bottom wall of the tub all about its circumference.   Air jets are formed by holes made in the tub wall with the longitudinal axis of the holes oriented less than 45° from the plane of the  bottom  wall.    The  jets  communicate  with  an  air distribution duct which is fed hot air under pressure by a blower.  Controls are also provided to vary the pressure of the air as well as the temperature thereof.   Warm air jets are released in the water contained within the tub to impart turbulence  in  the  body  of  water  to  create  acupressure massaging  flows  of  warm  air  jets  and  water  flows  from opposed sidewalls and end walls of the tub towards a central area of least turbulence and which is occupied by the body of a person.   The acupressure massaging flows perform a massaging action all about the body simultaneously.  The tub also includes  a back  massaging  cavity  to  simultaneously massage the back.   Hot air circulating in the distribution duct also heats the neck and back portion of the tub where the neck and back of the bather rests during treatment.

Title: Method and apparatus for improving the resolution of pulse position modulated communications between an implantable medical device and an external medical device
Inventor: FERNALD KENNETH WILSON
IPC: A61N1/372
Filed: 1995-10-31
Granted: 2001-06-19
Abstract: A method and apparatus is disclosed for use in an implantable device that communicates with an external device through pulse position modulation. A  timing generator is provided as part of said implantable device that determines the phase uncertainty between an external signal and an internal clock signal. The phase uncertainty then is added to the preset delay period to more precisely control the position of the response. The phase uncertainty is measured by a dual slope circuit that varies a state variable (which can be a digital timer, a capacitor voltage, or the like) at a fixed rate with either a positive or negative slope. When the external signal is detected, the state variable is reset and then decreased at a fixed rate until the next positive edge of the clock signal. The state variable then is increased at the same rate until the subsequent positive clock edge. The resulting variable value is proportional to the phase uncertainty. When the delay timer reaches zero, the state variable is again decreased at the same fixed rate until the initial value is reached, at which the output response is generated.
