IPC: A61M25/00
Filed: 1991-03-25
Abstract: A reinforced medico-surgical tube comprising a tube of flexible material, a filament helix coaxial with the tube and disposed between inner and outer peripheries of the tube, and a distal end of the tube, the distal end including a straight-cut or angle-cut axial end face disposed at an angle equal to or other than 90° with respect to a central axis of the tube.   The filament helix is separated into pieces at the distal end if the tube is angle-cut such that coils of the filament helix are  discontinuous  with  opposite  ends  of  the  coils adjacent the  end  face  of the distal  end.   The cut filament end in the case of a straight-cut tube or the cut  filament ends  in the case of  an angle-cut tube confront the axial end face and are separated therefrom by a thin layer of flexible material formed by melting the end face, melting a plastic piece onto the end face or by any other suitable method.   The end face can be radiused to provide a smooth rounded surface extending between the inner and outer peripheries of the tube at the distal end thereof.   One or more eyes can extend between the inner and outer peripheries of the tube at the distal end thereof and one or more secondary lumens can be provided in the tube.

Title: Process for producing anodic films exhibiting coloured patterns and structures incorporating such films
Inventor: JOZEFOWICZ MARK A
IPC: C25D11/22
Filed: 1991-05-09
Abstract: ABSTRACT OF THE DISCLOSURE      A process for producing a structure including an anodic film exhibiting a coloured pattern, and the resulting structures.  The process involves anodizing a surface of a metal substrate or article made of or coated with aluminum or an anodizable aluminum alloy to produce an anodic film preferably having pores extending from the film surface inwardly towards the underlying metal.  A semi-refective layer of a non-noble metal is then deposited on or within the pores of the film in order to generate a colour by effects including light interference.  Limited areas of the resulting film are then contacted with a solution of a noble metal compound (e.g.          Pd, Au or Pt) by a procedure which avoids the use of an adhering mask.  The noble metal from the solution at least partially replaces the non-noble metal in the contacted areas and creates a different colour in these areas.  The non-noble metal in the remaining areas may be fully or partially leached out, if desired, or the colour in the contacted areas may be changed by carrying out further anodization of the article, in which case the non-noble metal is also partially or fully leached away.  The result is a patterned anodized article in which the colours are highly resistant to fading or lack of uniformity.

Title: Method for metallizing dielectric surfaces containing a metal
Inventor: LAUDE LUCIEN D
IPC: H05K3/18
Filed: 1992-02-17
Abstract: ABSTRACT OF THE DISCLOSURE    "Method for metallizing dielectric surfaces containing a metal" The method for metallizing a dielectric surface according to the invention is carried out in two successive steps. The first step consists of irradiating the surface of the dielectric material by a previously adjusted laser beam (wave length, energy, energy density, irradiation time). The second step consists of immersing the piece of dielectric material after the irradiation into an autocatalytic bath containing the metal that one wishes to deposit. This deposit is formed by electroless plating only in the irradiated zones and follows exactly the geometrical profile of these zones. The remaining part of the surface, which has not been irradiated, is not coated by metal during the immersion into the bath. The characteristics of the metal deposit (thickness, profile, structure) are completely controlled by the irradiation characteristics and by the characteristics of the dielectric material and of the autocatalytic bath.

Abstract: The controlled impedance, low cross-talk, high density, EMI  shielded  electrical  connector  assembly  comprises  a receptacle connector and a plug connector for interconnecting circuits on mother and daughter printed circuit boards arranged orthogonally  or  in  other  configurations.    Each  of  the receptacle and plug connectors comprises in preferable form, four rows of electrical contacts arranged in two outer and two inner rows.   One set of inner rows and outer rows is each supported  in  an  insulator  of  dielectric  material  which surrounds each contact and extends between an outer and inner row in each set.  The contacts in the outer rows of each set are staggered with respect to the contacts in the inner rows. A conductive housing extends along the outer rows of contacts and further comprises a portion disposed adjacent the inner rows of contacts, the housing serving as a ground plane when connected to the boards.  The ground plane is spaced from the contacts at a selected distance that when combined with the dielectric material of the insulators provides a selected characteristic impedance.  Further, the conductive housing has a plurality of projections extending inwardly toward the outer rows  of  contacts  and outwardly toward the  inner  rows of contacts, the projections extending partially between each of the adjacent contacts in the respective rows to provide a conductive barrier for cross-talk protection.

Abstract: A microwave food carton having two integral layer-divider panels, and a one piece blank which may be erected to form the carton. Surface areas of the top and bottom walls of the carton, and the integral layer-divider panels, are each provided with a layer of microwave susceptor material so that they are directly heated thereby upon application of microwave energy. Such a carton is particularly useful in a microwave food package for microwave heating oppositely facing surfaces of each of a plurality of food pieces disposed in three layers in the package. In such a package, one of the integral layer-divider panels is disposed between each two adjacent layers of food pieces; the food pieces are preferably uniformly thick and have planar upper and lower surfaces; and the carton is preferably sized, relative to the sizes of the food pieces, to ensure a snug contacting relation between the microwave susceptor covered walls and panels of the carton, and the planar surfaces of each of the food pieces. An exemplary use of the carton is to package potato strips which are preferably parfried prior to packaging; and which, upon being microwaved for a sufficient period of time, become crispened on their outsides; and provide a crisp-exterior, meaty-interior eating sensation without having to be deep fried.

Title: Engine with an offset crankshaft
Inventor: MERKEL RONALD F
IPC: F16C3/06
Filed: 1992-05-12
Abstract: ENGINE WITH AN OFFSET CRANKSHAFT               ABSTRACT OF THE DISCLOSURE A new and useful improvement to internal combustion engines  is disclosed which  is an  engine  with  an  offset crankshaft.  When the crankshaft is rotated in a clockwise direction, the distance the piston travels from the top of the stroke (piston at maximum travel) to the bottom of the stroke (piston at the bottom of its travel) is greater than the diameter of  the  crankshaft rotation.   The angle  through which  the crankshaft moves during the downstroke is greater than 180°.  The engine therefore has a longer time power stroke than exhaust stroke.  The intake cycle is longer in time than the exhaust cycle which improves aspiration of the engine.  This concept can be applied to Otto cycle engines, Diesel engines, two stroke engines,  and may be applied to compressors.   When used in compressors,  the  intake  stroke  is extended which  improves aspiration.

Abstract: PRÉCIS Dans la présente invention, le but principal de l'Écono-neige est de changer la neige des rues en eau, pour être ensuite déversée dans les bouches d'égouts situées dans les rues de la ville. Pour ce faire, la neige qui est soufflée par la "souffleuse mécanique" est ejectée dans le compartiment à neige situé dans la partie supérieure de l'Écono-neige. Cette neige est ramassée par les palettes extérieures de deux moulins, tournant en sens inverse, situés sous le compartiment à neige, et est littéralement fondue par des brûleurs à gaz propane "directs" situés sur les côtés gauche et droit des moulins. Une fois fondue, la neige se déverse dans un petit réservoir, qui a la fonction de ramasser le sable et autres objets plus lourds que l'eau, pour ensuite être déversée dans le réservoir principal qui, à son tour, est déversée dans les bouches d'égout de la rue.
