Title: Rotary wooodworking tool
IPC: B27G13/02
Filed: 1980-07-24
Abstract: In a rotary woodworking tool having an elongated cutter blade 1 received in a peripheral seating 8 of a solid cylindrical support 6, one end of the cutting edge of the blade is offset angularly from the other end of the cutting edge, e.g. at least mating faces of the seating and blade are helical, and a cutting angle A defined at any point along the cutting edge between a leading face of the blade and a radius through that point is the same for all points along the cutting edge. As the tool rotates, there is obtained a shearing action at successive points along the cutting edge, as distinct from simultaneous impact of all points of the cutting edge with the workpiece and individual small zones of the cell and fibre structure of the wood being severed at any instant are supported by adjacent such zones to each side, whereby there is obtained a cleaner surface finish. <IMAGE>

Title: Alkenyl Isothiocyanates and Their Thiocarbamyl Derivatives
IPC: C07C335/12
Filed: 1980-08-29
Abstract: Both alkenyl isothiocyanates of formula   <IMAGE> where R is hydrogen hydrocarbyl or substituted hydrocarbyl, at least one R having 6-10,000 carbon atoms, and also thiocarbamyl derivatives of such compounds, are useful as additives for fuels and lubricants. The isothiocyanates may be made either by reacting an alkenyl chloride, e.g. chlorinated polyisobutylene, with KSCN to form a thiocyanate which then isomerises to the isothiocyanate, or by reacting an alkene, e.g. diisobutene, polyisobutene, isobutene/isoprene copolymer or EPDM, with Cl.SCN, removing HCl from the adduct to produce a thiocyanate, and then effecting thermal rearrangement to the isothiocyanate. The thiocarbamyl derivatives may be made by reacting the isothiocyanate with a reactive hydrogen compound, e.g. diethylene triamine, tetraethylene pentamine, benzylamine, N-aminopropyl morpholine, tris(hydroxymethyl)- aminomethane or 1,4,8,11- tetraazacyclotetradecane.

Title: Crop metering device
IPC: G01F3/38
Filed: 1981-06-09
Abstract: A crop metering device measures by volume the clean crop yield of a combine harvester during harvesting, wherein a trap 40 is located in the clean crop flow to build up a head of clean crop, and a paddle wheel 46 or analogous device successively releases known volumes of crop at a rate which tends to maintain a predetermined head of crop above the trap. A sensor 50 determines when the head of crop has built up to the predetermined level, and initiates successive operations of the paddle wheel or analogous crop releasing device. The volumes released are counted by a switch 52 or the like to determine yield in relation to time or harvested area. A weighing device (110), fig. 5 (not shown), may be incorporated to enable an on-board computer to effect a volume-to-weight conversion. <IMAGE>

Title: Packaging goods in pocketed trays
Inventor: REDPATH MAX TEAGO
IPC: B65B57/14
Filed: 1981-07-10
Abstract: In a method and apparatus for loading objects into the pockets of a compartmented tray (72), an in-line succession of abutting objects is advanced to a location over a plurality of gates (64 etc.) under which guide paths defined by chutes (68, etc.) extend in order, when the gates are opened, to guide the objects into the pockets (70, 84 etc.) of a tray located below the gates. The angles (???) at which the chutes are inclined differ to compensate for the spacing (86) that exists between the pockets. The objects supplied to the gates are ejected from a magazine (10) and scanned by a television camera (52), faulty objects, detected using the camera, being directed to a reject chute (34) by dipping a conveyor (30). The method and apparatus is especially suitable for use in the manufacture and production of multi-component foodstuffs, wherein the objects constitute self-supporting first foodstuff components eg. biscuits, and the tray loaded with such first foodstuff components is moved on to a station at which a non-self-supporting second foodstuff component, e.g. mallow is added, then to a station at which a closure seal is supplied to the tray and finally, possibly after sub-division of the tray, to a storage station at which the foodstuff can set whilst enclosed in its sealed environment. <IMAGE>

Title: Time division telephone switching systems
IPC: H04Q3/52
Filed: 1979-01-15
Abstract: A plurality of speech path units are controlled by a central processing unit. Each speech path unit includes a time switch which shifts a signal which is time-division-multiplexed from time slots of incoming highways to other time slots on outgoing highways, a digital trunk circuit and speech path control equipment. The time switch includes a speech path memory device divided into m<2> memory blocks (m > 2). The memory blocks have assigned thereto the column and row numbers of an mxm matrix. An incoming highway is accessed to a memory block address of a column of the matrix corresponding to that incoming highway, and similarly with the outgoing highways whereby to treat a plurality of said time slots as a group. This increases the time switch capacity without redundant use of the memory.

Patent GB-2090822-A (GB)
Title: Binderless zeolite extrudates and method of producing same
IPC: B01J20/16
Filed: 1981-12-01
Abstract: Binderless zeolite sieve extrudates are made by extruding a mixture containing about 40-60% zeolites with the remainder being a metakaolin clay that has mixed with it about 90-120% of the stoichiometric amount of sodium hydroxide to convert the clay to a zeolite. After extrusion the particles are allowed to dry age during which time most of the clay is converted to the zeolite. A further heat treatment in a dilute caustic aqueous solution ensures complete crystallization with subsequent washing and calcination to produce an adsorbent product. The extrudate particles can be dried under dry, bulk conditions in a container during which time autogeneous heat develops to convert the clay to zeolite.

Title: Cam system for double-cylinder knitting machines
IPC: D04B15/32
Filed: 1982-03-16
Abstract: A cam system for circular double- cylinder knitting machines is provided for controlling sliders (3), swingable intermediate selector jacks (2) and selector jacks (1). When knitting only ground loops the upper ends (21) of the jacks (2) are swung out of their tricks so that they are controlled by a raising cam edge (91) to lift the jacks (2), the sliders (3) and the needles into the clearing position. When knitting both ground loops and tuck loops the selector jacks (1) are either lifted by a raising cam (131) or not according to a pattern. Lifting of the jacks (1) by the raising cam (131) results in the jacks (2) being lifted by a raising cam (10) so as to lift the sliders (3) already raised by a cam (9), and the needles into the clearing position. Otherwise the jacks (1) and (2) are not lifted and the sliders (3) lifted by cam (9) pass onto a tuck cam (4) into the tuck position. <IMAGE>

Title: Ink drop duplicating system
Inventor: BOBICK THOMAS WALTER
IPC: H04N1/195
Filed: 1982-10-01
Abstract: An ink drop duplicating system which operates efficiently at high speed and at high resolution employs a plurality of ink drop print heads (4) extending at an angle to the scan direction to reproduce an original document (1). The heads (4) print a set of contiguous bands (5) collectively covering an area of the copy sheet (2) to be printed. Each printing head (4) produces a row of drop streams which are individually controlled to deposit printing drops at a plurality of printing positions along a line extending perpendicularly to the major axis of the printing head. Printing control information for the ink drop printing heads is generated by a photosensing array (3) which extends across one major dimension of an original document (1) and which is scanned across the other major dimension. Scanning data is stored on a magnetic disk (7). After one or more original documents have been completely scanned, the scanning data is read from the magnetic disk (7) and reorganized to produce drop control signals (10) for the ink drop printing heads (4). <IMAGE>
