Patent CA-1325253-C (CA)
Title: Demand defrost control method and apparatus
Inventor: WHITE LEE A
IPC: F25B13/00
Filed: 1988-07-18
Granted: 1993-12-14
Abstract: Demand Defrost Control Method and Apparatus Abstract A demand defrost controller for a heat pump.  The controller compares the temperature of an outdoor heat exchange coil with an enable temperature.  A timer is activated when the coil temperature is less than the enable temperature.  When the timer senses the compressor has run for a predetermined time the controller checks outdoor and coil temperatures to determine if a defrost cycle of the heat pump should be conducted.  A defrost cycle is achieved by reversing refrigerant flow in the heat pump system for a predetermined period or until the outdoor heat exchange coil has been heated to a termination temperature.

Abstract: ABSTRACT OF THE DISCLOSURE          A solenoid valve, especially an outlet valve for infusion water.  A valve chamber (2) is accommodated in a valve housing (1) and communicates with a supply channel (Z) and with a drain channel (A) by way of a valve seat (3).  The magnetic armature (6) of a magnetic system accommodated on valve housing (1) is connected to a valve plate (10) accommodated in the valve chamber (2) opposite the valve seat (3).  The valve chamber (2) is sealed off from the interior (11) of the magnetic system by an isolating diaphragm (12).          To prevent calcium deposits, the valve seat (3) has a sheet (13) of polytetrafluoroethylene accommodated coaxially along its inner circumference and projecting beyond the surface of the valve seat (3) on the side facing the valve plate (10).          The upper edge of the sheet (13) facing the valve plate (10) is in a sealing plane with respect to the valve plate.  The valve plate (10) consists of a resilient material that is softer than the sheet (13), and the surface that faces the valve seat (3) is radially at an acute angle to the sealing plane in the vicinity of the contact areas.

Abstract: Abstract of the Disclosure Kayak safety sponsons having two pa rallel inflatable tubes along the water-line on each side of the kayak adjacent the cockpit. These tubes join together below the waterline by means of material such as straps and above the waterline at both ends by a fastener such as a strap with a quick-release buckle, at each end of the cockpit. They can be attached and inflated by the kayaker seat-ed in the cockpit while using a paddle. Deflated, the sponsons are flat and tightly drawn against the hull by the two fasteners for minimal water resist-ance. Inflated, the sponsons taper toward both ends for minimal water resistance, increasing maximum waterline beam of the kayak adjacent to the cockpit area but not affecting foreward and aft  lines of the craft, permitting normal handling due to minimal change in underwater lines and minimal increase in water re-sistance.

Title: Modulator with two-stage orificed master cylinder bypass valve
Inventor: REUTER DAVID F
IPC: B60T8/40
Filed: 1988-11-17
Granted: 1992-11-10
Abstract: MODULATOR WITH TWO-STAGE ORIFICED   MASTER CYLINDER BYPASS VALVE Abstract of the Disclosure A vehicle wheel brake system having a service braking section and a wheel lock control (ABS) section. Under certain conditions the wheel lock control section may not be able to generate sufficient pressure to operate the vehicle wheel brakes when the master cylinder output pressure has been isolated therefrom. When such conditions occur, the displacement piston of the ABS control section moves to open a bypass valve which connects master cylinder output pressure to the vehicle wheel brake even though the ABS system has isolated it from that wheel brake. The bypass valve is a two-stage orifice valve arrangement which provides orifice control of master cylinder pressure during initial brake actuation and provides two stage valve opening action when the master cylinder output pressure is to be delivered to the wheel brake to actuate that brake irrespective of the attempted control of the wheel brake by the ABS section of the brake system. This therefore effectively returns the vehicle braking system to service braking until the vehicle operator releases the brake system.

Abstract: ABSTRACT         An automatic concentrate fertilizer injection system for fertilizing plants in a greenhouse.  Water is pumped through a combination pressure damper and flow stabilizer for regulating the water to a continuous flow.  Concentrated fertilizer is injected into the continuous flow of water at a first predetermined rate of injection, and concentrated acid is injected into the flow of water at a second predetermined rate of injection.  The water, acid and fertilizer are combined within a mixing chamber to produce a diluted fertilizer mixture.  A desired p/H level and fertilizer solubility (i.e. concentration) level is programmed into a control unit of the system.  The diluted fertilizer mixture flows into the control unit which in response detects the actual p/H and concentration levels.  The control unit then generates frequency impulse signals having frequency proportional to the difference between the desired and detected p/H and concentration levels.  The frequency impulse signals are transmitted to pumps for controlling the respective rates of injection of acid and concentrated fertilizer into the flow of water, thereby maintaining the desired p/H and fertilizer concentration levels of the mixture.

Granted: 1992-12-08
Abstract: ABSTRACT OF THE DISCLOSURE         Disclosed is a transfer-type plasma torch which may be used to heat objects, e.g., to heat molten steel at a certain stage of being supplied from a converter to a continuous casting mold  After a trigger electric discharge has been produced between the cathode and the ignition anode of the plasma torch, electric discharge is effected between the cathode and an object to be treated that is set as the anode.  The plasma torch includes a cylindrical cathode-holding member having therein a space allowing the flow of coolant, an ignition anode disposed within the cathode-holding member, and a ring-shaped cathode disposed on an inner periphery of the cathode-holding member and positioned below the tip of the ignition anode, with the tip portion of the cathode projecting downward from the bottom face of the cathode-holding member.  This arrangement makes a conventionally-provided nozzle unnecessary, thereby enabling a reduction in diameter of the entire torch while enabling a relative increase in diameter of the cathode.  Thus, the plasma torch is capable of exhibiting a large capacity for arc current.

Abstract: A cooling abnormality detection system for electronic equipment includes a protection unit with two temperature sensors arranged in each piece of electrical equipment.   A temperature difference measuring means receives the measured temperatures from each piece of equipment, and outputs a sensor failure signal when the absolute value of a difference between the temperatures measured by the two temperature sensors exceeds a first predetermined value.  An abnormal temperature signal is output from the temperature difference measuring means when the two measured temperatures both exceed a second value.   The sensor failure signal  is transmitted to the electronic  equipment,  while  generation  of  the  abnormal temperature alarm interrupts power supply to the electronic equipment.
