Title: Point of lube monitor
Inventor: KAMIS PETER A
IPC: G01P13/00
Filed: 1991-06-26
Abstract: ABSTRACT OF THE DISCLOSURE A piston-type point of lubrication magnetic flow indicator providing a barrel interfit with a bushing having a cylinder portion penetrating the barrel coaxially and a magnetic piston which reciprocates closely interfit inside the cylinder portion of the bushing.  Lube oil enters an inlet port of the bushing, flows through a check valve into the cylinder portion, and impinges on one end of the magnetic piston.  The impinging causes the magnetic piston to move in the cylinder portion uncovering at least one port formed through the cylinder portion which opens the cylinder portion to the barrel, directing flow thereto.  The lubricating oil flows through the barrel and out of an aperture formed at a forward end of the barrel to a lubrication spray nozzle.  Movement of the magnetic piston through the cylinder portion triggers a magnetic reed switch mounted on an outside circumference of the barrel and generally overlying the relative axial position of the piston in the cylinder portion.  The opening and closing of the reed switch can be electrically monitored by electronic lubrication monitoring systems or controls as are known.

Title: Method for the separation of hfa 134a
Inventor: TAYLOR ANDREW M
IPC: C01B/
Filed: 1991-06-26
Abstract: A method for separating HFA 134a from an HFA 134a-rich mixture thereof with HF and/or HCFC 1122 which comprises feeding the mixture to a distillation column to separate an azeotrope or near-azeotrope of HFA 134a and HF and/or HCFC 1122 from a residue comprising substantially pure HFA 134a. Starting from an HF-rich mixture of HFA 134a such as a typical product stream in HFA 134a production, the method includes a first distillation step to separate HF from the initial mixture and produce an azeotrope or near azeotrope of HFA 134a and HF which is an HFA 134a-rich mixture.

Abstract: ABSTRACT INJECTION MOLDING MACHINE AND STATIONARY MOLD CARRIER FOR USE WITH A CENTER GATE MOLD AND AN OFF-CENTER GATE MOLD     By an injecting unit, which is horizontally shiftable at right angles to the injection axis, plastic material is adapted to be injected into injection mold sections which can selectively be fixed to a stationary mold carrier. The moldside ends of piston rods of the advance-retract cylinders of the injecting unit are contained in and adapted to be fixed to sleeves provided on a sleeve carrier, which is slidably mounted on the mold carrier. Between the sleeves, the sleeve carrier is formed with an opening for receiving the plasticizing cylinder of the injecting unit. The sleeve carrier substantially covers the cylinder-receiving opening of the mold carrier in those areas which are not occupied by the plasticizing cylinder at a time. In such an injection molding machine it is possible to provide injecting units in which the piston rods of the advance-retract cylinders lie in a horizontal plane.

Patent CA-2057400-A1 (CA)
Title: A clock buffer with adjustable delay and fixed duty cycle output
Inventor: TRAN THANH T
IPC: H03L7/08
Filed: 1991-12-11
Abstract: A clock buffer circuit for a computer system, and a computer system incorporating the same, are disclosed. The clock buffer circuit includes a differential input buffer for receiving the input clock signal, with its output coupled to the input of a phase locked loop (PLL). The switching level of the differential input buffer is adjustable, either by adjusting the DC bias applied to the input clock signal, or by adjusting the reference signal, which changes the point in the cycle of the input clock signal at which the differential buffer switches. The PLL synchronizes its output to an edge of the output of the differential buffer, but maintains the same duty cycle (e. g., 50%). Accordingly, the clock buffer circuit may have its delay adjusted, by modifying a voltage divider, applying a variable voltage, or programmably via a digital-to-analog converter, to match the delays of other clock buffer circuits in the computer system, reducing the clock skew in the system. A sine wave may be used as the input cloak signal, so that harmonic noise is reduced in the system.

Title: Tool holder
Inventor: VELTMAN HANS
IPC: B23B49/00
Filed: 1991-12-13
Abstract: ?          ABSTRACT          TOOL HOLDER     The invention relates to a tool holder comprising a coupling piece for coupling to the chuck of a drilling or screwing machine, wherein the coupling piece comprises at least one body that is received movably in radial direction in a carrier, wherein the body is movable to a position engaging onto the holes arranged in the chuck by a movable locking element and wherein a tool clamped in the chuck can be received inside the tool holder, wherein the locking element is movable in axial direction.      Such a tool holder finds application for instance in the use of a drilling or screwing machine wherein operations are performed requiring the alternating use of two tools. An example of this is the making of screw connections, wherein holes are drilled and screws are rotated into the drilled holes.      The axial movement of the locking element has the result that the actions for locking the tool holder on and releasing it from the chuck take place in the same direction as the respective movements with which the tool holder is placed on the chuck and taken therefrom.

Optical pulses are sensed by a photodiode, and if the pulse width is narrow enough to yield sufficient spectral energy within the bandpass of the tuned circuits, a "laser occurred" indication will be produced by the processing circuitry.  Automatic adjustment of the detected output for non-laser incident radiation is made by varying the signal level into a sequential detection logarithmic amplifier by a voltage proportional to the integral of the incident radiation over a short period of time.

Abstract: A lining material for pipe lines, especially those buried in the ground such as sewage pipe lines and a process for providing such pipe lines therewith are disclosed, which material comprises a flexible tubular film, a resin-impregnated sheet covering the outer surface of the flexible tubular film, and a tubular covering material having a strong resistance to tensile force. The sheet may be constructed by several units of sheet fractions arid is overlapped in both lateral end portions so as to be slidable each other in opposite directions to form a tubular sheet. The lining material is applicable for repair/and reinforcement to the inner surface of a pipe line having damages portions. According to the process of this invention thermocuring of the lining material applied onto the inner surface of a pipe line can be carried out by moving a nozzle for jetting pressurized steam from one end to the other end of the pipe line without applying high pressure to the pipe line. Thus, the present invention is particularly suited for applying a lining material to a superannuated sewage pipe line or general sewage pipe lines having damaged portions.
