Title: Antifreeze self-spraying and -warming windshield wiper
Inventor: LAPLANTE SYLVAIN
IPC: B60S1/52
Filed: 1991-11-07
Abstract: Antifreeze self-spraying and -warming windshield wiper ABSTRACT OF THE DISCLOSURE           A wiper  for an  automobile windshield glass pane.  The elongated rubber wiper defines  an  anchoring  bead and  a blade integral  to  the  bead.    The  blade  has  a  lip portion and a lengthwise  V-shape  channel  defining  a  mouth  about  the  lip portion, so  that a  pair of  spaced lips  be defined.  A U-shape metal casing is embedded into the blade U-channel,  and is heated by a  wire made from a material having a high electric resistance and through which runs  an electric  current provided  by the car battery.    A  hose  is  frictionally  engaged  into the U-casing lengthwisely thereof, and connected to the antifreeze liquid tank under the  car hood.  The hose has a number of bores, for passage of the antifreeze  towards  the windshield  through  the channel mouth.   The wire  casing will  warm the antifreeze liquid in the hose and the wiping element including  its blade  as well  as its bead.

Title: Valve arrangements
Inventor: LANGLEY KEITH W
IPC: B60T11/32
Filed: 1991-11-12
Abstract: ABSTRACT OF THE DISCLOSURE            A valve arrangement comprises an inlet port (?),  an outlet port (?), a valve member (?) normally adopting a valve arrangement open position in which fluid flow from the inlet port (?) to the outlet port (?) is permitted via a choke (?), and a fluid chamber (?).  The inlet port (?) is connected via another choke (?) to supply fluid to the fluid chamber (?) to urge the valve member (?) to a valve arrangement closed position.  The two chokes (? ?) determine that upon flow of fluid from the inlet port (?) to the outlet port (?) the fluid pressure in the fluid chamber (?) tends to rise more slowly than the fluid pressure at the outlet port (?) and so the valve member (?) is urged to remain in the valve arrangement open position by the effect of the fluid pressure at the outlet port (?).  If this fluid pressure is insufficient, either because of an existing rupture downstream of the valve arrangement or because such a rupture occurs, the fluid pressure in the fluid chamber (?) asserts itself to move the valve member (?) to the valve arrangement closed position.

Inventor: MILLER JAMES J
IPC: A01N63/00
Filed: 1991-11-25
Abstract: Abstract:   The invention is a body dusting powder for external use, containing a live yet dormant bacterial culture which may consist of various strains of bacteria knownto inhabit the intestinal tract of the human body, particularly strains of lactobacillus and bifidus, and including especially, lactobacillus acidophilus and bifidobacterium, and also including a suitable growth medium for same.   When the invention is applied to external areas of the human body such as feet, hands, underarms, scalp, rectal and genital areas, for example, bacterial cultures contained in the powder are revived in the presence of moisture due to perspiration, and the cultures grow and multiply, feeding on the growth medium provided, producing lactic acid and other antibiotic substances, thereby inhibiting other micro-organisms normally found growing in these areas, as well as those found in the air which may alight upon these areas.   When applied to the human or animal body, the invention prevents and controls the growth of undesirable organisms such as cornybacterium, propionibacterium acnes, diptheroid bacteria  in general, staphylococci, streptocooci, coliforms, and fungae and yeast such as candida or tinea pedis.   The invention inhibits the spread of sexually transmitted and contagious diseases which may be due to organisms which enter the skin and the body from the air, which might otherwise be transmitted through body to body contact.

Title: Can coater with improved deactivator responsive to absence of a workpiece
Inventor: STIRBIS JAMES S
IPC: B41F31/04
Filed: 1992-01-09
Abstract: ABSTRACT     An offset blanket print/coat assembly for printing or coating rotating containers has a blanket wheel supporting a plurality of blanket assemblies by means of radial frame plates and an air cylinder operable for retracting the blankets inwardly on the blanket wheel.       The blanket assemblies move in both a radial direction and an axial direction in moving from a printing position to a stop-print position in response to the detection of the absence of a container of a mandrel  approaching  the  printing  position.    Novel  inker blade adjustment means adjusts the fountain blade relative to the fountain roll both inwardly and outwardly relative to the fountain roll and holds the blade edge in various desired positions along its entire length by the adjustment of individual adjustment members positioned along the blade length.  A plastic seal is urged from a slot in each side plate of an inker fountain against the end of the fountain roll and provides a lightweight and secure liquid seal between the seal and the fountain and also between the lower end of the seal and the fountain blade to minimize ink leakage.  The ink rolls are cooled by lubricating oil pumped through them and then sprayed into the gear case of the gears driving the ink rolls so as to cool the rolls and the gears and provide required gear lubrication.  Oil from the sump of the gear cases passes through a temperature control unit for cooling the oil prior to the pumping of the oil back to the ink rolls.

Filed: 1992-03-09
Abstract: Abstract of the Disclosure:            A method for testing a valve being driven by an electromagnet having a magnet armature,  includes determining a value of current intensity in the magnet as a response current inten-sity, at an instant when motion of the magnet armature of the valve begins during a switching action of the valve.  A force acting through the magnet upon the magnet armature is deter-mined from the determined response current intensity, at the instant when motion of the magnet armature begins, by means of a calibration function,  as a response force and as a standard for the condition of the valve.  An apparatus for testing a valve being driven by an electromagnet having a magnet armature and an electrical circuit, includes a current intensity meter in the electrical circuit of the magnet.  A computer is connected to the current intensity meter.  A memory for a calibration function is connected to the comput-er for indicating a dependency of a force acting upon the magnet armature on a current intensity in the electrical circuit of the magnet.

Title: Converter bypass piston for reduced idle loss
Inventor: HALL ARTHUR III
IPC: F16H61/50
Filed: 1992-11-02
Abstract: CONVERTER BYPASS PISTON FOR REDUCED IDLE LOSS          Abstract of the Disclosure An axially oriented annular piston is provided in the torque converter.  It encircles the converter pump.  The piston has an open and a closed position. In the open position, a portion of the fluid exiting the converter pump bypasses the turbine, passing through an axial gap between the pump and the turbine. Having some of the fluid bypass the turbine reduces the amount of fluid impinging on the turbine, thereby reducing the torque induced in the turbine by the fluid.  When the piston is in the closed position, all of the fluid is directed toward the turbine, maximizing the torque developed.  Springs keep the piston in the open position at rotative speeds at or below an engine idle speed.  As the rotative speed of the pump is increased beyond engine idle, a centrifugal chamber opposed to the springs fills with fluid and forces the piston to the closed position.
