Granted: 1991-11-19
Abstract: ABSTRACT OF THE DISCLOSURE A hinge pin is temporarily held on a first hinge member on the automobile body by means of a hinge pin support mechanism.  A door to be attached to the automobile body is held in position, and a second hinge member on the door is brought into engagement with the first hinge member.  The hinge pin is pressed into the second hinge member through the first hinge member to couple the door to the automobile door.  The hinge pin support mechanism includes a hinge pin retaining member including a ring separably joined to a plurality of legs.  When the hinge pin is pressed into the hinge members, the ring is sheared off from the legs and rides in a peripheral groove defined in the hinge pin.  The ring then engages one of the hinge members to prevent the hinge pin from being removed from the hinge members.  The door can automatically be attached to the automobile body by a door attaching mechanism and detached from the automobile body by a door detaching mechanism.

Title: Two stage blender
Inventor: ZIMMERLY ROBERT D
IPC: B01F25/64
Filed: 1987-08-27
Granted: 1991-03-05
Abstract: Abstract of Disclosure A two stage blender is capable of handling high viscosity liquid-powder mixtures.  The mixture discharged from the first stage is directed to the second stage, from which it is discharged at a relatively high discharge pressure.  The second stage further enhances the natural vacuum created within the first stage, so that powder is fed at a constant ratio for a wide variety of liquid flows.  Selected internal parts of the blender are designed to permit cleaning the blender in place.

Title: Plating bath for electrodeposition of aluminum and process for the same
Inventor: KATO YOSHIO
IPC: C25D3/44
Filed: 1987-09-01
Granted: 1992-12-22
Abstract: ABSTRACT OF THE DISCLOSURE       In a plating bath for electrodeposition of aluminium, comprising a nonaqueous electrolyte using a eutectic mixture fusible at room temperature, the plating bath comprises a mixture of about 40 to 80 mol % of an aluminum halide and about 20 to 60 mol % of butyl pyridinium halide, or further comprises an organic solvent mixed in said mixture.

Patent CA-1322897-C (CA)
Inventor: UEBEREGGER HENRY

Filed: 1987-10-14
Granted: 1993-10-12
Abstract: ABSTRACT OF THE DISCLOSURE           A foil sheet comprising a plurality of layers is continuously rolled up around a shaft extending in its longitudinal direction to form a tubular body in such a manner  that  the  two edges  overlap.    For welding,  the overlapping edges are pressed together between two belts driven such that they rotate in the longitudinal direction. The inner belt traveling inside the tubular body has a longitudinal groove, which at least partly receives the area of the overlapping edges.  The longitudinal groove shapes the inwardly oriented region of the seam of the tubular body and prevents plastic material that has been liquefied for welding purposes from stretching uncontrollably as a result of the pressing force.   It is thereby assured that the material of both edges is welded completely together, so that there are no squeezed-out edge areas of liquid material that can prematurely cool down and as a result not bond properly to the layer of material facing them.

Abstract: ABSTRACT OF THE DISCLOSURE    A novel cast, resiliently-deformable gasket is provided herein for supporting a sewer pipe in a manhole opening and sealing the space between the walls of the opening and the surface of the sewer pipe.  The gasket includes a generally-pentagonally-shaped, relative large mass and substantial thickness main body portion.  A cylindrical flange member is integral with the main body portion and is in the form of a staight leg portion terminating in an "L"-shaped foot.  A web of substantial thickness but which is nevertheless of less thickness than that of the main body portion. extends radially-inwardly at an acute angle from the main body portion.  The web terminates in a rim portion of torroidal form, which is integral with the web and having an inner diameter less than the outer diameter of the pipe.  The cylindrical flange and at least half the mass of the main body portion are adapted to be secured in situ within the manhole at the manhole opening.  This gasket is sufficiently resilient to compensate for stress in shear, is sufficiently flexible to accomodate extensive misalignment of the sewer pipe, and yet is capable of affording an absolute fluid-tight seal in the rim of the manhole opening.  The torroidal rim provides a sealing tension where it contacts the sewer pipe.  The gasket moreover is easy to install, comparatively inexpensive to make, and extremely reliable in use,

Title: System for off-the-air reprogramming of communication receivers
Inventor: DAVIS WALTER L
IPC: H04B7/26
Filed: 1987-12-31
Granted: 1991-07-09
Abstract: ABSTRACT      A communication receiver is disclosed which can decode signals transmitted by radio frequency propagation.  A programmable controller uses instructions in a non-volatile reprogrammable memory to decode and process the signals, and to output the information contained in the signals in a useable form.  The controller also responds to predetermined signals by decoding and processing information for new decoding and operating instructions, and stores the data in a temporary memory.  Logic circuitry responds to subsequent predetermined signals to enable selective reprogramming of the non-volatile reprogrammable memory by data stored in the temporary memory to alter the decoding characteristics of the receiver.

Title: Retroreflective sheet coated with silica layer
Inventor: HUANG TZULI J
IPC: B32B27/40
Filed: 1988-03-08
Granted: 1995-07-11
Abstract: Retroreflective sheeting has been improved by a coating comprising silica and a transparent polymer selected from aliphatic polyurethanes, polyvinyl chloride copolymers having a minor amount of a comonomer containing at least one carboxylic acid or hydroxyl moiety, and acrylic polymers. Silica comprises 10-80 weight percent (10-70% in the case of polyacrylates) of the transparent protective coating. For example, a solution or dispersion of polyurethane is mixed with a silica sol and possibly other ingredients (e.g. wetting agent, UV light absorber and adhesion promoter), and the composition is coated onto the retroreflective sheet and dried. The coated retroreflective sheeting has superior soil and dew repellancy, retaining a higher percentage of original brightness after exposure to dirt and/or dew conditions.

Abstract: ABSTRACT OF THE DISCLOSURE The analog implementation of a television signal transmission system includes a line integrator for developing a first analog signal corresponding to low frequency components, that is, the average level of active video below 15 KHz during each horizontal line of signal.  An A/D converter produces a digital value corresponding to the first analog signal and a D/A converter develops a second analog signal corresponding to the digital value.  The second analog signal is subtracted from the baseband video signal to develop the high frequency components of the video signal.  The digital value is encoded in the horizontal blanking interval of the high frequency components which is modulated onto an RF carrier.  A one horizontal line delay in the baseband video signal is introduced before subtraction.  In the digital implementation, a digital average is taken of the active video below 15 KHz of each line and subtracted.  In the receiver, the coded data is decoded to reconstruct the low frequency components signal, which is added to the high frequency. components video signal to reconstruct the television signal.

Abstract: ABSTRACT         A method of packaging a beverage and a package structure has a cylindrical tube 1 over an end 3 of which is located a partition wall 2 having a restricted orifice 6.  A closure wall 7 is located over the partition wall 2 and both walls are sealed, for example by crimping, to the rim of the tube 1.  A primary chamber 4 is formed within the tube and a secondary chamber 8 is formed between the partition wall 2 and closure wall 7 which chambers communicate through the orifice 6.  Chamber 4 is charged with beverage 11 containing gas in solution and sealed with an end wall 12 crimped to the rim 9 of the tube 1.  Prior to sealing the chamber 9 is dosed with liquid nitrogen or carbon dioxide so that headspace 13 in that chamber is pressurised.  The package adjusts to a state of equilibrium in which beverage flows into the secondary chamber 8 to form a headspace 14 therein.  Upon opening of the package with a pull tag 15 a pressure differential between the headspace 14 and 13 causes beverage and/or gas in the chamber 8 to be ejected through the orifice 6 into the beverage 11 and thereby gas in solution in the beverage to be liberated and form, or assist in the formation of, a head of froth on the beverage.
