Title: Sack lift
IPC: B66C23/44
Filed: 1979-06-14
Abstract: In order to provide a readily mounted sack lift for use on an agricultural tractor 1, a jib 6 is pivotally mounted on a post 5, which itself is supported by a vertically extending support 10 with lateral extensions 22. The assembly is supported on the upper link 3 and lower links 4 of the conventional three point linkage and at 27 and 25 provides three points in the manner of the three point linkage for attachment of an implement shown as a spreader 11. When the hopper of the spreader 11 needs refilling the tractor 1 is driven adjacent a sack of the appropriate material and the linkage 3, 4 lowered so that both the spreader 11 and the support 10 are in contact with the ground. Hydraulic pressure supplied through line 9 from the tractor 1 to cylinder 8 raises the jib 6 to lift the attached sack over the spreader 11 for emptying therein. <IMAGE>

Title: Apparatus for joining edges
IPC: B29C63/18
Filed: 1979-09-07
Abstract: An apparatus for butt jointing opposite edges of a sheet of plastics material to form a tubular sleeve for use as a printing forme comprises two opposed elongate platens (1 and 2) and clamp means (3), Figure 1 (not shown), to clamp the platens together to sandwich the edges of the plastics material to be joined between them. At least one of the platens includes a strip heater 15, Figure 2, extending along it with thermally insulating material 18 extending along both sides thereof. Preferably, the heater 15 has embedded therein two low power electrical heating elements 16 and a single high power element 17. The thermally insulating material 18 ensures that portions of the plastics material adjacent the opposite edges of the sheet are held firmly in place throughout the heat welding operation to ensure that the completed joint is substantially void free and stress free. The heater 15 and the insulating material 18 are enclosed in a polytetrafluoroethylene sleeve 19. The apparatus may also include nip bars 4 to enable opposite edges of the sheet of plastics material to be clamped into position before the platens are brought together. Adjustable springs 13 or an inflatable hose (24), Figure 6 (not shown), apply pressure at the nip between the platens. The platen 2 may have thereon a polytetrafluoroethylene coating 6, Figure 2, or a curved polytetrafluorethylene strip (21), Figure 4 (not shown). <IMAGE>

Title: Process for the Separation of Anthraquinone Compounds using Fractional Crystallisation
IPC: C09B1/36
Filed: 1979-10-11
Abstract: There is described a simplified process for separation of certain alpha , alpha '- disubstituted anthraquinones of the formula   <IMAGE>  in which R<1> represents hydrogen or an optionally substituted alkyl, cycloalkyl or aryl group, R<2> represents an optionally substituted alkyl cycloalkyl or aryl group, Y represents the link -CO-, -SO-, or -SO2, and one Z represents the group   <IMAGE> whilst the other represents a hydrogen atom, from mixtures also containing  alpha -monosubstituted and  alpha , beta '- disubstituted anthraquinones which comprises fractional crystallisation of the mixture. The process is especially useful for separating the waste liquors arising after separation of the majority of both the 1,5- and 1,8- anthraquinone disulphonic acids formed by the conventional mercury catalysed disulphonation of anthraquinone. The waste liquors are first halogenated to produce mono and dihalogenated anthraquinones and then all halogens in the  alpha - positions are acylated and the resultant mixture separated by fractional crystallisation.

Title: A method for reducing desorption from an alloy of a rare gas formed by transmutation of one element of the alloy and an alloy thus obtained
IPC: C22C43/00
Filed: 1979-11-28
Abstract: Desorption from an alloy of a rare gas formed by transmutation of one element of the alloy is reduced by forming the alloy in a single phase by increasing the concentration of one element in the alloy with a non- transmutable isotope of the element. The method is primarily applicable to the fabrication of tritiated targets e.g. tritiated titanium and erbium for sealed neutron tubes, the non transmutable isotope used being deuterium.

Title: Texturised water-insoluble milk materials
Inventor: SMITH DAVID GRAYSTON
IPC: A23L1/00
Filed: 1982-05-07
Abstract: A water-insoluble milk based foam material is produced by heating a milk based liquor in a manner so as to increase the temperature of the liquor relatively rapidly and substantially uniformly throughout its volume to a temperature at which foaming and protein denaturing occurs but below that at which the Maillard reaction occurs. Because of the insoluble nature of the resulting material it finds particular application as a foodstuff for use as a breakfast food (intended to be eaten with milk), and also as a snack product and third world foodstuff. Heating is preferably effected by exposure to microwave energy or radio frequency energy, or possibly also by induction, resistance or ohmic heating.

Title: A brake disc for a vehicle disc brake
Inventor: WIRTH XAVER
IPC: F16D65/12
Filed: 1982-09-28
Abstract: The disc carries at its radially inner periphery a retaining flange 5 split up into flange portions 10 by radial recesses 9. The retaining flange 5 serves to mount the brake disc on a hub via a pair of axially spaced and parallel conical surfaces 7, 8 which engage corresponding surfaces of the hub. The flange portions 10 are provided with axial holes 11 to form structures which are flexibly distortable in a peripheral direction in the area of their connection to the annular body 2, so that differential thermal expansion between the annular body 2 and the retaining flange 5 can be absorbed by flexible distortion of the flange portion 10, without causing unduly high inner stresses in the brake ring. It is possible to reinforce the flange portion 10 with axial reinforcement ribs 12 without noticeably influencing their flexibility, which serves to further absorb differential thermal expansions. <IMAGE>
