Abstract: ABSTRACT OF DISCLOSURE     A ball bearing for linear motion which is particularly useful in applications where the "open type" ball bearing is in combination with a shaft supported along its length which is sub-jected to radial forces primarily toward or away from the open side of the bearing.     The ball bearing for linear motion consists of a bear-ing sleeve adapted to position a plurality of bearing segments on its inside surface.  Each bearing segment contains a closed loop of circulating balls.  The closed loop has one straight track of load bearing balls and one straight track of non-load bearing balls.  The bearing segments are circumferentially positioned within the bearing sleeve so as to maximize the capacity of the bearing when load is applied either toward or away from the open side of the bearing.

Abstract: Form 22 Abstract The instrument named "Practise Finger Board" is of pocket size.  While musical stringed instruments have ample room to install separated strings and tuning machine heads (used to apply string tension) the Practise Finger Board has a devised method of adjusting string tension in a confined space.  Each string starts at a string-keeper, encircles a plastic type material nut, over the top of a metal top section, over an opposite nut and returns to a string guy where a tension nut is adjusted to a required tension.  A 1 3/4" hole on the top of said top metal section is not intended to emit musical sounds; nor is the instrument meant to have its strings tuned to recognized notes.  However, the said tension of said string can be adjusted to that required of a tuned musical instrument (by use of a 1/4" nut driver) allowing an operator to practise quietly and unobstrusively: 1) pick techniques and rhythm; the use of finger and thumb picks 2) also the use of fingers in finger picking, without picks, (as in instrumental playing) can be practised - and the varying techniques 3) the string order of tuning an instrument can be established 4) because of its ease of portability, it permits extra and quiet practice of the many chords needing practice up to 5th fret.

Abstract: Abstract of the Disclosure Apparatus is disclosed for conducting relatively hot molten thermoplastic material from a furnace and delivering the material at a desired homogeneity to a remote location.          The apparatus includes a conduit means having an inlet adapted to receive the material at one end from the furnace and an outlet for delivering same to the remote location.          There may also be provided a flow control device in flow communication with the outlet of the conduit means for regulating the flow of the thermoplastic material from the furnace at a controlled rate and head.  A refractory structure located in spaced relation about the conduit means and flow control device defines a space thereabout for the introduction of thermoplastic material.  Means is provided for blocking or preventing flow communication between the furnace and the remote location exterior of the conduit means thereby preventing flow of thermoplastic material in bypassing relation with the conduit means.  The conduit means, flow control device and blocking means are preferably fabricated of an oxidizable refractory metal and are maintained immersed in thermoplastic material when exposed to temperatures above an oxidation temperature thereof.  Heat exchange may be provided for temperature control of the glass.    A method is described for conveying and conditioning the thermoplastic material and blocking flow communication of the material exterior of the flow path between the inlet and the outlet end thereof.

Abstract: ABSTRACT      Apparatus for electroplating flat planar workpieces e.g. printed circuit boards has a receptacle for containing the electrolyte solution and a conveyor for transporting racks supporting the workpieces through the receptacle with the workpieces moving in their own plane.  The electrolyte is pumped to a manifold in the bottoms of the receptacle with towers extending upwardly from the manifold in longitudinal rows on each side of the path of the workpeices.  The elec-trolyte is sprayed toward the workpieces from nozzles on the towers.  A primary power supply is connected between the racks for the workpieces and containers of pellets of the metal to be plated which are immersed in the electrolyte.  An auxiliary power source is connected between the workpiece racks and insoluble electrode grills between the towers and the workpeice path.  The spraying arrangement allows the el-ectrolyte to be sprayed at high pressure and flow rate against the surfaces of the workpiece, and the insoluble electrode grills can be at a potential different from that between the workpiece and the metal to be plated to enhance the plating characteristics and permit high speed plating at high current densities.
