Title: Method for producing a tungsten carbide tip punch
Inventor: PENG DA H
IPC: B21D39/00
Filed: 1986-09-18
Granted: 1991-01-08
Abstract: ABSTRACT OF THE DISCLOSURE     A method is used for producing a tungsten carbide tip punch which includes a punch rod and a tungsten carbide piece of a hardness greater than that of the punch rod.  A crown-like indentation is formed in the bottom surface of the tung-sten carbide piece.   A brazing material is applied to the vertices of the crown-like indentation and around the inter-engaging surfaces of the punch rod and the tungsten carbide piece.  The cylindrical protrusion of the top surface of the punch rod is pushed into the crown-like indentation of the tungsten carbide piece by a hydraulic activating apparatus so that the top of the cylindrical protrusion is formed, along the vertices, into a crown-like shape to join the punch rod and the tungsten carbide piece together.   Both the brazing material and the interengaging surfaces are vacuum heated to enable flow of the molten brazing material over all the in-terengaging surfaces thus further bonding them together.

Title: Electronic temperature control for cordless iron
Inventor: FOSTER ROBERT W JR
IPC: D06F79/02
Filed: 1987-09-23
Granted: 1991-02-12
Abstract: ELECTRONIC TEMPERATURE CONTROL MEANS FOR CORDLESS IRONS          ABSTRACT OF THE DISCLOSURE An electronic temperature control means for a cordless ironing apparatus is described. The temperature of the sole plate of the iron is sensed by a thermistor embedded therein; the thermistor is part of an astable multivibrator circuit, and any change in temperature of the sole plate causes a change in resistance of the thermistor, and a corresponding change in frequency at the output of the multivibrator.  This output drives an infrared LED, and the light emitted by the LED in the iron is sensed by a phototransistor in the base, which relays the sensed temperature information to a microprocessor therein which controls the current applied to the heating element accordingly, to maintain the desired temperature of the sole plate.

Abstract: LOGICAL RESOURCE PARTITIONING OF A DATA PROCESSING SYSTEM ABSTRACT The embodiment discloses a method and means for partitioning the resources in a data processing system into a plurality of logical partitions. Host control code may be embodied in programming, microcode, or by special hardware to enable highly efficient operation of a plurality of preferred guest programming systems in the different partitions of the system. The main storage, expanded storage, the channel, and subchannel resources of a system are assigned to the different logical partitions in the system to enable a plurality of preferred guest programming systems to run simultaneously in the different partitions. This invention automatically relocates the absolute addresses of the I/O channel and subchannel resources in the system to their assigned partitions. Also the absolute and virtual addresses of the different guest programming systems are relocated into, as well as page addresses for any expanded storage, their assigned partitions. The guest programming systems generally will be different operating systems. The logical CPU(s) of the guests are dispatched on one or plural real CPUs in the system using the S/370XA SIE (start interpretive execution) instruction. Special operations are provided, including the CPU alerting of other guests in different partitions using I/O interruption signalling. Interception is provided to handle special circumstances.

Title: Fluid control valve
Inventor: NEWCOMBE HAYDN J
IPC: F16K11/20

Granted: 1991-08-06
Abstract: ABSTRACT FLUID CONTROL VALVE    A water tap has a closure member in the form of a rubber or like cup    located in a chamber in carrier   ?. The base of the cup extends across the port    which is to be closed when the tap is in "off" condition and the base of the cup has a hole    registered with the port in that off condition.  Hence water can flow into the cup and the water pressure in the cup acts to hold the cup on the seat whereas pressure in the port acts against the base of the cup in the opposite direction but on a smaller area of cup.  Hence the higher the water pressure the better the seal.
