Abstract: ABSTRACT              MOLTEN METAL CASTING AND FEEDER      SLEEVES FOR USE THEREIN           Molten metal is cast in a mould having a feeder cavity, which may be defined by a feeder sleeve (1), whose surface has a plurality of elongate projections or ribs (6) spaced apart around its perimeter, the number and dimensions of the ribs being such that the volume of the feeder cavity is reduced by at least 20% compared to a feeder cavity of generally the same size and shape but without the ribs.  Preferably the ribs extend substantially the full length of the inner surface (7) of the feeder sleeve (1).

Abstract: ABSTRACT                              "Organoclays"   An organoclay material adapted specifically for use in a given system is selected by testing the system with organoclays made using a range of quaternary ammonium compounds having varying average carbon chain lengths, particularly by reacting suitable clays with mixed quaternary ammonium compounds, in order to determine the optimum C to N ratio in such quaternary ammonium compounds for that system. An organoclay is then manufactured substantially in accordance with the optimum ratio by utilising: one or more selected quaternary ammonium compounds designed substantially to achieve the optimum C to N ratio or a single quaternary ammonium compound which affords said C to N ratio.

Abstract: ABSTRACT OF THE DISCLOSURE    A text orientation system for dot matrix printers includes a character adjust logic for orienting an image to be printed relative to a physical page,  A first register in the character adjust logic receives A word of memory for either placement or character address.  Each word has base bits and orientation bits.  When the word is for address, the first register separates the base bits from the orientation bits and forwards the base bits to an adder and the orientation bits to an orientation adjust logic.  Other bits of orientation adjust from a character processor are loaded into a second register and then to the orientation adjust logic for combining with orientation bits.  A resulting adjusted signal goes to a Mux for selecting a displacement to produce a displacement signal.          The displacement signal is then added to the previously separated base bits and forwarded as an adjusted character address to a character generator address.  When the word is for placement, the first register also separates the base and orientation bits.  The base bits are forwarded to a microprocessor in the character processor.  The orientation bits are adjusted in the orientation adjust logic similar to the orientation bits of the address.  The resulting adjusted signal also goes to the microprocessor in the character processor.

Abstract: An Apparatus and Method for Wrapping an External Tape Support About a Filter Element Assembly An automatic wrapping apparatus for wrapping an external tape support about a filter element includes an indexable turret assembly having a plurality of filter element clamps rotatably mounted at spaced radial positions on the indexable turret. Means are provided at one of the radial positions for rotating a filter element clamp about a longitudinal axis. The wrapping apparatus also includes means for selectively varying the position of the strand of tape along the longitudinal axis during rotation of the clamp. Further, the apparatus includes means for severing the strand of tape and wrapping the severed ends about a respective pleated filter assembly. A method for wrapping an external tape support about a pleated filter element includes clamping a pleated filter between opposed face surfaces, contacting one end of a continuous strand of adhesive coated tape with an outer pleated edge surface of the pleated filter assembly carried in the clamp fixture, rotating the filter element assembly about a longitudinal axis and simultaneously move the position of the taped material in one direction along the longitudinal axis to spirally wrap the tape externally about the pleated filter element. After wrapping, the filter element is indexed to a second radial position and the trailing strand of tape is severed, producing a loose end which is pressed into contact with the outer edge surfaces of the pleated filter element. The present invention is particularly useful in the automatic assembly of cylindrical filter cartridge elements.

Title: Production of coated metallic or ceramic - particles
Inventor: DONALD E BAKER
IPC: C23C14/22
Filed: 1968-03-19
Abstract: Coarted particles are produced by passing the particles through a vapour and continuously changing the attitude to ensure a uniform coating. The particles are recycled through the vapour to build up the coating. Agglomeration and sticking of the particles is prevented by advancing them across the surface on which they are subjected to the vapour, while periodically disengaging the particles from the surface. This is done by imparting a period motion to the surface which is abrupt for part of each period. Uniformly coated particles are produced without sticking or agglomeration.
