Title: Apparatus for forming molten liquid plastics into strands or filaments
IPC: B29C48/08
Filed: 1975-09-15
Abstract: 1480692 Supplying plastics to extrusion devices C F SCHEER & CIE 15 Sept 1975 [14 Sept 1974] 37891/75 Heading B5B  Molten plastic is delivered from a container to a processing device, such as a spinneret, by distributing apparatus so constructed that, when necessary for cleaning &c., the plastic can be shut off from the spinning head and kept re-cycling moving through the distributer and container with no "dead" corners where stationary plastic can collect. In the embodiment illustrated in Fig. 1, plastic is supplied from tank 10 to housing 22 having an outlet 28 which can feed spinning head 34 or, as illustrated, be closed by sliding shutter 36. Flushing port 40, adjacent to the outlet 28, provides a back flow to valve 24 and via connection 44 to container 10. Valve 24 is opened completely when the plastic is simply recycling, and partially closed when filaments are being spun. This partial closure permits a small back-flow of plastic which keeps the apparatus continuously flushed. Piston 38 is used to move spinning head 34 and shutter 36 along rail 32 to start or stop the spinning. In either mode pump 18 is kept working, but excessive back pressure does not build up. Fig. 2 illustrates an embodiment in which two containers 100A and 100B are connected to the outlet 120, which, as before, may be closed or used to feed a spinning head. Valves 164A and 164B permit the supply from tanks 100A and 100B respectively to pass through to orifice 120 or be cut off. In the position illustrated valve 164A is open and the supply from tank 100A is being used for spinning, a proportion of the plastic recycling through flushing line 160 through choke valve 132, partially closed as spinning is in progress, through multipleway valve 134 to connection 154A and the supply tank. As valve 164B is closed any plastic in 100B is kept recycling through supply line 106B, U- shaped port 124B, return line 128B, fully open choke valve 136B and connection 154B to tank 100B. As the supply from tank 100A is used for spinning choke valve 136A is partially closed to permit a small proportion of the plastic to return via line 128A and keep it scoured. Should it be desired to connect tank 100B to the spinneret instead of 100A then valve 164A is shut and 164B opened, multiple-way valve 134 connected to 154B instead of 154A, valve 136A fully opened and 136B partially closed. Filllers 156A and 156B are provided in the return circuit.

Title: Improvements in or relating to balers
Inventor: MURRAY PATRICK ANTHONY MOLTENO
IPC: A01F15/10
Filed: 1967-08-25
Abstract: 1,244,302. Hay balers. P. A. M. MURRAY, and D. CRAIG. 21 Aug., 1968 [25 Aug., 1967], No. 39269/67. Heading B5F. A pick-up baler comprises a backwardly sloping wheeled chamber provided at its rear end with a normally closed tail gate 3 and at its forward end with a packing plate 6 reciprocated by beams 18 and 23 pivoted to rotatable arms 17. Material picked up by rotary tines mounted at the forward end of the chamber is fed upwardly into the chamber in small discrete amounts by orbitally reciprocated packing fingers 14 carried by arms 17. The charges are directed into the chamber along a feed passage defined by a fixed curved panel 11 and a series of strips 12 depending from the plate 6. In operation, as each charge is forwarded into the chamber through opening 13 it is compressed by strips 12 and is moved upwardly toward the top of the chamber by the action of the succeeding charge and by the plate 6 which has a small upward component of movement. A series of vertical stacks of charges is thus built up in the chamber and the bale as it increases in size moves backwards against the pressure of twine 44 and sprung members carried by the walls of the chamber. When the chamber has been filled the twine is knotted across the feed opening 13 by a knotter unit located at X, the twine being fed to the knotter by needles 29 which reciprocate across the feed opening. Retraction of the twine needles 29 actuates a trigger 57 which releases catch 51 to allow the gate 3 to partially open under its spring biasing. As the next bale is built up the preceding bale is forced partially out of the chamber, thus fully opening the gate and allowing the bale to be removed. After removal of the bale the gate swings shut and is latched in position whilst the rest of the succeeding bale is formed.

Abstract: 1,261,416. Preserving fruits and vegetables. FYNS KONSUM INDUSTRI A.S. 6 Aug., 1969 [9 Aug., 1968], No. 39420/69. Heading A2D.  Starchy fruits and vegetables are preserved by contacting the fruits and vegetables with hot steam containing sulphur dioxide, the content of sulphur dioxide being reduced to zero during the last part of the steam treatment. The sulphur dioxide-containing steam may be generated by heating water containing a compound which will evolve sulphur dioxide on heating in sodium metabisulphite. Prior to the above treatment, the fruit and vegetables may be blanched. A suitable apparatus for carrying out the above processes is shown in Fig. 1 wherein the fruit or vegetable is placed in treating chamber 14. Steam is passed through the line 20 to the water chamber 16 containing water having dissolved therein a sulphur dioxide generating material. The sulphur dioxide-containing steam is generated in chamber 16 and passes through the sieves 17 to contact the fruit or vegetable. Steam may be exhausted from the apparatus through the lines 40. The apparatus may be held at a reduced pressure by the use of a pump connected to the main line 44. The amount of sulphur dioxide generating material is such that towards the end of the process, pure steam is generated in the chamber 16. At the termination of the process the fruit or vegetable may be removed by the use of a screw conveyor 13 and mashed in the mashing apparatus 62, 64. The process is particularly applicable to the production of mashed potato and yam.

Woodworking apparatus for sawing, moulding or routing comprises a base 1, a tool carriage 21 slideable on rod and tube members 11, 12 of a subframe and arcuate projections 14 on side arms 13 of the subframe engaging arcuate grooves 15 in frame arms 2 to support the sub-frame for adjustment of the tool about an axis parallel to the top of a slotted worktable 3 so that the working angle of the tool 10 relative to the table top can be varied. The base 1 has a single aperture 5 but the apparatus can be rotatably attached to a bench and the table top is in two parts adjustably secured by bolts 8 in elongated slots and located by studs in spaced holes so that the width of the tool slot 7 can be varied. For holding the sub-frame in adjusted angular position, a long bolt 16 passes through arcuate slots 17 in the two frame arms and through the tube member 12 and at one end has a clamping nut 19. For indicating the amount of angular adjustment, a pointer 51 co-operates with a scale 52 on an arcuate slot 47 through which passes a rod 46 for traversing the carriage 21 along the members 11, 12. The switch 50 for a driving motor on the carriage 21 may be incorporated in the handle 49 of the rod 46. The motor and reduction gearing to a tool spindle 36 are carried by a casing 33 which can be raised and lowered on posts 27, 28 by screw threads 27b on the post 27 and in a bearing 39a. A swing knife 42 for the saw 10 is attached to the motor casing 33.

A bracket 53 having a split socket 58 for a fence arm 59 can be fitted to a screw 54 by a screwed collar 55 and is located by studs 57 and 57a. To adapt the apparatus for spindle moulding, the rod 46 is removed and the bolt 16 is fitted through alternative holes 62 in the frame arms after the sub-frame has been through 90 degrees so that motor spindle is positioned beneath a hole in the table to one side of the slot 7. If a routing cutter is fitted, the slot 7 is widened by moving back one half of the table so that the cutter can project through the slot. The first Provisional Specification describes an open tubular cradle with a square frame in which a rotatably-adjustable slotted work-table is secured in angularly-adjusted position by tightening a flexible band. The tubular slideway carrying the tool carriage is adjustable up and down pivoted arms by rack and pinion means. A sawing fence has clamps at each end for securing it to the table frame and, for moulding, a fence provided with a bearing for the tool spindle may be fitted.
