Abstract: Disclosed is an improved window sash latch for use in a pivotal window sash adapted for installation in a master frame of a double-hung sash window assembly. The latch has a housing having a top wall having an access opening therethrough, a pair of opposing side walls and a single end wall extending between the side walls. Each of said side walls and the end wall extend from said top wall and have a free end opposite the top wall. There is a latch bolt slidably received in the housing and having a top wall, two opposing side walls and two opposing end walls. Each of the side walls and each of the end walls extend from said top wall and have a free end opposite said top wall. The first end wall is generally perpendicular to each of the side walls. The second end wall forms a beveled end arranged to be engaged in a guide rail for locking the window sash against pivotal movement.

Abstract: Disclosed herein is a method of coating a substrate with a zinc dialkyldithiophosphate (ZDDP) material, comprising the steps of selecting a substrate which is reactive with said ZDDP material; providing an atmosphere containing said ZDDP material at a predetermined concentration; exposing said substrate to said atmosphere for a sufficient period of time and at a sufficient temperature, so as to cause said ZDDP material to form a layered substrate having a layer of a ZDDP derivative material thereon; and annealing said layered substrate.

Abstract: The present assembly relates to a link assembly for a chair. The assembly includes a frame link for connecting to a frame of the chair and a back support link for connecting to a back support of the chair. The frame link and the back support link are pivotably connected in order to facilitate displacement of the back support according to movement of a back frame of the chair. An adjustable pivot point is located on one of the links for selectively adjusting the extent of displacement of the back support relative to the back frame.

Abstract: A composite high Tc superconductor film is applied to a substrate, said film as applied having a thickness of at least 5000 Angstrom and an outer surface having an average roughness not exceeding 250 Angstrom.

Abstract: A cable television monitoring system to monitor the return signals of a CATV system is disclosed. The system monitors the CATV system in a frequency range of 5-225 MHz and measures voltage and frequency parameters. The system provides an analysis in NTSC compatible base-band video which, when modulated to TV channel frequency and sent downstream in a cable TV system can be received at any point in a cable TV system.

Abstract: A liquid removal system having an interface device and a vacuum source are described. The interface device has a porous membrane with an entrance zone on one side. The vacuum source maintains a vacuum on the side of the membrane opposite the entrance zone when the membrane is wetted. Liquid which contacts the wetted porous membrane is removed from the interface device by the vacuum source.

Abstract: A kit for students to carry out biotechnology experiments in a classroom, comprising a plurality of first containers, each of the first containers containing a sample of a prepared substance for use in the experiments; at least one of the prepared substances including a biologically derived constituent; each of the prepared substances having constituents selected for their safety in a classroom experiment, while being representative of a substance used in an industrial experiment. A plurality of second containers are also provided, the second containers being arranged to receive a number of test samples of substances to be tested. A number of aids are also provided to allow the students to carry out the experiments in the absence of instrumentation used in the industrial experiment, along with a set of instructions to permit the students to carry out the classroom experiment and thereby to better understand the industrial experiment.

Abstract: An improved unicycle is disclosed. The unicycle has a forked stem with a pair of tines. A wheel is rotatable mounted on the tines and a seat is connected to the stem. The stem has a first rod extending rearwardly from the stem and a second rod at the end of the first rod opposite the stem. The second rod extends in a direction transverse to the wheel direction of travel and generally parallel to the axle of the unicycle. The second rod has handle at each of the first and second ends.

Abstract: An improved stretcher system is disclosed. The stretcher system has a first horizontal stretcher support member having a first end and a second end and a vertical stretcher support member having a first end and a second end. The first end of the horizontal stretcher support member is removably connected to a wall surface. The second end of the horizontal stretcher support member is connected to the first end of the vertical stretcher support member. The second end of the vertical stretcher support member is removably connected to a floor surface. Also disclosed is a second horizontal stretcher support member having a first end and a second end and a second vertical stretcher support member having a first end and a second end. The first end of the second horizontal stretcher support member is also removably connected to the wall surface, the second end of the second horizontal stretcher support member is connected to the first end of the second vertical stretcher support member.

Abstract: Disclosed herein is a modular motor comprising a discoidal stator unit and a discoidal rotor unit rotatable about an axis of rotation under a torque established therein, the stator unit being supported by a frame arrangement and having a winding assembly within in a matrix of polymer material, the winding assembly including a number of winding elements, each of the winding elements having a pair of radially disposed portions, wherein at least one of the radially disposed portions of each winding element is spaced from a radially disposed portion of another winding element to form a cooling region therein, the cooling region being arranged for the location therein of thermally conductive materials having a thermal conductance of at least 1.5 w.multidot.cm/(cm.sup.2 .multidot..degree.
