Title: Improvements in or relating to the coating of granular materials with powder
IPC: A01C1/08
Filed: 1944-01-28
Abstract: 574,985. Weighing - apparatus. GIRLING, A., SUTTIE, K. R., and SCOTTISH AGRICULTURAL INDUSTRIES, Ltd. Jan. 28, 1944, No. 1622. Addition to 554,015. [Class 143] [Also in Groups I and II] The powder feed mechanism described in the parent Specification is modified to simplify refilling. It comprises a continuous travelling band 43, which is shown in Fig. 1 in relation to the hopper 1, weighing device and mixer 38 of the parent Specification. This band is moved through a predetermined distance, synchronously with delivery to the mixing apparatus of a predetermined weight of granular material. A powder-retaining structure, into which powder is fed, has a removable cover 47, Figs. 1, 2, and is mounted in contact with at least a part of the upper surface of the band 43. Powder is carried by the belt through a gap or aperture in the forward face 48 of the structure and discharged into a container 5 from which a shoot 37 leads to the mixer 38. Rotating wipers 56 and a brush 50 on shafts 41, 42, respectively, facilitate delivery of the powder from the belt. The powder feed band 43 is driven from the shaft 6, on which the compartmented drum 7 of the weighing device for the granular material is mounted, through a shaft 26 to which it is coupled by gears having a step-up ratio of I : 3. The shaft 26 carries a variable crank 49 connected to a ratchet arm 50 which moves a ratchet wheel 51 to drive the band 43 through a chain 52, wheel 43 and roller 45 to advance it a predetermined and adjustable amount each time the three-compartmented weighing device turns through one-third of a revolution. Fig. 3 shows a modified arrangement of powder feed mechanism, wherein the band is carried on rollers 61, 62, 63, the roller 61 being carried in bearings free to move horizontally under the action of springs, to hold the rollers 61, 62 to grip and drive the band. The upper run of the band is supported on a -board 66. The arrangement reduces tension in the band. A wiper 67 assists in discharging the powder from the band. Instead of reciprocating the ratchet arm 50 by a crank 49 and shaft 26 to move the band, this may be done by an upright lever connected at its upper end in an adjustable manner to the arm 50 and at its lower end to the frame of the machine and intermittently actuated by a three-spoked striker carried on the shaft 6. Delivery of the grain may be stopped, when the charge of powder in the container is exhausted, e.g. by giving an audible warning or knocking a spring-loaded driving clutch out. of action when the roller 4 of the belt 43 has turned a predetermined extent.

Abstract: 1,025,452. Gas-fuelled lighters. A. RACEK. Jan. 17, 1964 [Jan. 25, 1963], No. 2201/64. Heading F4F. A gas-lighter has a replaceable gas tank 20, Fig. 1, having a gas outlet valve 22 closed by a spring 24 and with a shoulder 25 on liftable valve stem 23; a disc-like rocker lever 26 permanently surrounds stem 23 and is engaged by a nose 27 on arms 7 pivoted to the part cylindrical case 1 on pivots, the arms 7 being fixed to cover 3 and attached to the limbs 19 of a member 18 whereby an over-centre spring 16 biases the cover to the closed or open position. A housing part 14, pivoted on pivot 5, engages below a slide member 13 supporting flint spring 12. The friction wheel 6 is rotated on opening of the cover 3 by a driver 8 on the cover engaging and rotating a driver wheel 9 connected to wheel 6. On opening of the cover, arms 7 pivot rocker lever 26 against a fulcrum 28 to engage shoulder 25 and raise the valve stem 23 to open the valve. The fulcrum 28 is of sprung metal and is attached to the case 1, a portion 31 being engaged by a conical ring 32 which is slidable to adjust the amount by which the fulcrum 28 extends into the case 1 and hence the degree of opening of valve 22. In Fig. 2, not shown, the stop shoulder is a nut which is adjusted on the stem to vary the valve opening; and in Fig. 3, not shown, the tank has a screw-threaded engagement with the case to adjust the rocker lever range. In Fig. 4, the nose 27c engages between two teeth 47 on a lever part 26c which bears on a fulcrum part 48 on the tank, the valve stem 23c being raised by a member 35 against spring 24c to move valve member 43 from passage 41. Throttling members 45 are inserted between a plate 40 and portion 39 of the tank and by screwing valve member 38 into portion 39 the members are accordingly compressed to control the flow rate of gas. The member 38 is held against rotation by a splined engagement 46 with parts 26c, 48 and engagement of part 26c with nose 27c so that rotation of the gas tank, which is limited by a lug 51 and a stop 52, adjusts the position of member 38.

Title: Improvements in or relating to the manufacture of polyurethane foams
IPC: C08G77/385
Filed: 1964-01-17
Abstract: Foamed polyurethane material is prepared by reacting an organic polyisocyanate with a hydroxyl group-containing polymer containing at least two isocyanate reactive groups per molecule under such conditions that a foam forming gas is generated, the reaction being carried out in the presence of a polysiloxane containing at least one unit of general formula <FORM:1087081/C3/1> where R stands for a monovalent hydrocarbon radical which may be substituted, X stands for the residue of a phenolic compound XOH and a for 0, 1 or 2.  Examples are linear polysiloxanes of formula <FORM:1087081/C3/2> where R and X are as above and n is an integer, preferably when n is greater than 10, and <FORM:1087081/C3/3> where p and q are integers, preferably when p is at least 3 and the sum of p and q is at least 10, particularly when p is 12 and q is 20 or p and q are each 9. Examples of phenolic compounds XOH are 2,4,6-trichlorophenol, 2,4-dibromophenol and 2,4-dichlorophenol.  The hydroxyl group containing polymer may be a polyester, polyesteramide or a polyether and is preferably a polyether having secondary hyhydroxyl groups. The preferred amount of polysiloxane is from 0.1 to 5.0% by weight of the polymer.  The polysiloxanes are prepared by reacting together a polysiloxane containing silicon bonded hydrogen, a phenol and a catalyst in the presence of an inert solvent. Typical catalysts are stannous salts and dialkyl tin salts.  Alternatively, they may be prepared by an interchange reaction of a phenol XOH with a polysiloxane containing -Si-OR1 groups, where R1OH is more volatile than XOH. Similar catalysts are employed. Blowing agents may be carbon dioxide produced in situ or inert low boiling liquids, e.g. fluorinated alkanes. Many polyisocyanates are mentioned, the preferred one being tolylene diisocyanate. Catalysts for the polyurethane formation include tertiary amines, e.g. triethylene diamine and soluble organic compounds of heavy metals, e.g. stannous octoate.  In examples, the hydroxy-group containing polymer used is a polyoxypropylene triol obtained by reaction of glycerol and propylene oxide.

Abstract: 931,099. Axial-flow fans. WILMOT-BREEDEN Ltd. Jan. 18, 1962 [Jan. 20, 1961], No. 2345/61. Class 110 (1). [Also in Group XXVII] A fan impeller comprises variablepitch blades controlled directly or indirectly by a temperature-sensitive element fitted in a central body part of the impeller and facing upstream of the latter so that in use an air flow induced by rotation of the impeller impinges on the element. Fig. 2 shows a fan impeller for cooling a motor vehicle radiator 1 and comprising variable-pitch blades 2 carried by a hub 5. A collar 25 on the end of each blade spindle 3 carries an eccentric pin 26 engaging in a slot 27, Fig. 4, in a rod 18. The stem 14 of a wax-filled thermostat 12 is screwed into the hub 5, the body of the thermostat being engaged by four ribs 16 projecting radially inwardly in a central hole in a disc 9. Axial movement of the disc 9 produced by the thermostat 12 causes axial movement of the rods 18 against the action of springs 23 to vary the pitch of the blades 2. At low temperatures the blades 2 are in fully-feathered position, with each pin 26 engaging a transverselyextending portion 28 of the slot 27. At the maximum-pitch position shown in Fig. 4, the pin 26 enters a longitudinally-extending portion 29 of the slot 27, and further temperature increase therefore produces no further increase of pitch. To ensure that heated air from the radiator 1 flows over the thermostat 12 even when the blades 2 are fully feathered, auxiliary centrifugal impeller blades 24 are provided on the back of the disc 9 to draw air through the spaces between the ribs 16.
