Patent CA-2031172-A1 (CA)
IPC: A61F5/058
Filed: 1990-11-29
Abstract: ABSTRACT OF THE DISCLOSURE     There is provided a head immobilizer of the type which can be attached to a rigid backboard support, with the head immobilizer including a base and a pair of laterally extending side support panels.  Each of these side support panels  further comprises an inner panel and an outer panel, with the inner panel being conformable  appropriately  to  a  shape  necessary  to snugly support a head to be immobilized.   The inner panel  also  includes  an  opening  which  effectively divides a portion of that inner panel into a pair of spaced inner support members extending laterally from the base.  The outer panel has inner and outer edges, and is hingedly attached adjacent its inner edge to the inner panel such that it is foldable relative the inner  panel  to provide a substantially rigid brace for   securing   the   inner   panel   in   a   desired immobilizing position.  The outer panel also includes a cutout portion for providing substantial access to the opening of the inner panel when the inner panel is braced in a desired  immobilizing  position.   The outer  panel  can  be  secured  in  a bracing position relative  the  inner panel,  and  the  outer  panel includes   an  attachment  panel  hingedly  attached adjacent its outer edge for securing the outer panel in bracing position adjacent the base.

Title: Process and apparatus for feeding a web of material to a processing machine, especially a packaging machine
Inventor: FOCKE HEINZ
IPC: B65H20/32
Filed: 1991-01-23
Abstract: A b s t r a c t The  invention  relates  to  a  process  for controlling the drive of a reel of a continuous web  of  material  which  is fed  to a processing machine (packaging machine). The web of material forms a material reservoir  upstream  of  the  pro-cessing  machine.  The  invention  is based on the object to improve this process such that the reel can  be  driven  as continuously  as  possible  for  refeeding material into the material reservoir. For this purpose,  the  filling  of  the material  reservoir  is  (continuously)  determined  and the drive of the reel is driven in dependance on  the  reservoir filling,  such  that  the  filling  does  not  fall  below a minimum filling and does not exceed a maximum  filling.  The reservoir  filling is preferably determined by means of com-paring the reservoir outflow with the  reservoir  inflow  as well  as  by  a more direct method, preferably by an optical scanning or weighing. The invention  further  relates  to  a feed apparatus for conducting this process.

Title: Current mode multiplexed sample & hold circuit
Inventor: BENGEL DAVID W
IPC: G11C27/02
Filed: 1991-03-15
Abstract: Abstract of the Disclosure A sample and hold circuit is disclosed in which differentially coupled input stages are multiplexed to drive a common output stage.  In this way, a plurality of input stages can be employed wherein the transition between sample and hold modes produces greatly reduced switching transients.  The circuit has very high overall gain so that sampling accuracy is improved and a very low current input stage configuration permits the use of small hold capacitors without introducing excessive droop in the hold mode.  The differential balance is completed by a dummy hold capacitor which is switched along with the hold capacitor.          Both of these capacitors are switched in a virtual ground config-uration.  Also, disclosed are means for producing an auto zero input condition, means for adding a correlation feature for improved digital performance and means for injecting controlled offset potentials so that the sample and hold means can be employed as either a DA converter or an AD converter in either a pipelined or recirculating converter state.

Abstract: Abstract " E S C A R " is a New Type of  Vehicle which is able to cancel and optimize the Lateral  Forces applying over the Passengers. These Forces are virtually unavoidable and are produced by the Centripetal (Inertial) Actions or by the Improper Road Conditions (basecally  due to Lateral Slopes).            Emphasizing the Idea of  solving  the problem  mainly from the "point of view" of the Passenger(s), I  want to let everybody know that the other Inertial Forces produces by the positive or the negative acceleration are also taken into consideration.   A Phisical Demonstration of the facts is to introduce you into the problem and further more examples of "what" is done are to emphasized no infringement with the " E S C A R ", due to its perfect aproach of the theory. More, there is no infringement with...four wheel vehicles, by any means.   The  " E S C A R "  is not a three wheel vehicle which might be forbidden in many countries in the world due to turn overs!  But it is partialy inspired by this.  It is actually a two wheel vehicle with two side wheels. And it has a tilting capacity in order to cancel the unwanted forces.   This vehicle is to be made of  three main parts: the Frame, the Body and the Engine.  It is conceptualy accepted that the Engine related components to be easylly desmounted and ... mounted, in an entire unit. I also intend to offer to this vehicle a range of versatility, in order to achieve water floating and snow slidding capabilities.   A modern concept of modulated units is to be presented, in order to join together more "E S C A R S", or to join it to Cargo Units (Modules), for exemple.     If we accept to use the trigonometrical function of the tangent in order to determine  the tilting angle, than, either manualy  or  automaticaly, we have to follow the relation: tg .alpha. =     where  .alpha.  is  the Angle coresponding to the tg  .alpha.    (the arctg  ), 1/g   is a constant related to the Gravitational Acceleration g, v is the linear (tangental) Speed of the vehicle, and r is the Radius of the curve.            In conclusion   the  Angle of Tilting will be directely dependent on the square of the Speed and indirectely dependent to the Radius of the curve!
