Filed: 1972-11-09
Abstract: 1389711 Cartons REED INTERNATIONAL Ltd 2 Nov 1973 [9 Nov 1972] 51813/72 Heading B8P A carton of cardboard or corrugated board and folded from the blank shown in Fig. 1, has portions 13, 14, 19 that form corner posts in the erected carton so that filled cartons can be supported one on another. Flaps 6 extending from sides 2 have oblique slots 8 so that the flaps 6 can be interlocked and handholds 9 will register with handholes 16 in end walls 4. Alternatively, outwardly folding flaps in the end walls may form handles. Extensions 17 on the end walls are folded inwardly to enclose the flaps 6 and tongues 21 engage slots 22 in the base 1. The side strips 19 on the extensions 17 lie against the portions 13 to reinforce the corner posts. The corner posts which are triangular when folded from the blank shown in Fig. 1, may alternatively be of square cross-section. A cut-out 15 in each flap 6 ensures an even height for all four sides of the carton, alternatively the end walls may be lower than the sides.

Title: Improvements in or relating to tubes for hydraulic and pneumatic cylinders
IPC: B21C23/32
Filed: 1965-12-09
Abstract: 1,124,608. Extruding. OSTROJ, NARODNI PODNIK. 9 Dec., 1965 [10 Dec., 1964], No. 52248/65. Heading B3P. [Also in Division F2] In a method of cold extruding a steel tube for hydraulic and pneumatic cylinders the blank is lubricated with a metallic surface film of thickness 10 to 60 microns. A blank formed from a steel tube is electroplated with copper or copper and cadmium and extruded with a punch 3 between a die 4 and a ring 5 on a mandrel 2 to form a tube 7 having a flange 8. When the extrusion is completed the mandrel 2 is raised to eject the tube 7 from the die and then held whilst the mandrel is pulled down again. In another embodiment, Fig. 8, a cylinder having a closed end is formed by backwardly extruding a solid blank which has previously been phosphate coated to form a cup 17. The cup is then heat treated, electroplated and further extruded to form a cylinder. During extrusion the metallic surface film serves as a lubricant and becomes partly diffused into the body of the tube. Colza or other oil may be used to provide additional lubrication during extrusion. A detachable insert 28, Fig. 11, may be used in the die 29 and it may have notches to form a cylinder having a rippled exterior.

Title: Method of drying microbial cells particularly yeast cells
IPC: C12N1/16
Filed: 1971-11-10
Abstract: 1373116 Yeast &c. KANEGAFUCHI KAGAKU KOGYO KK 10 Nov 1971 52262/71 Heading C6F [Also in Division A2]  A method of drying microbial cells, particularly yeast cells, obtained by cultivating microorganisms on petroleum hydrocarbons (including methane), methanol or acetic acid as carbon source involves evaporating by heat volatile matter contained in the cells, which have been recovered from the fermentation liquor by conventional methods, over a constant drying rate period until the falling rate sets in and heattreating the obtained product in a drying atmosphere at a temperature 65‹ and 120‹C for at least 30 minutes. Such heating breaks the membranes of the cells and denatures the protein to permit ready digestion by animals. The micro-organism may be one of the species of yeasts, bacteria or moulds particularly mentioned. Use of a mixture of Candida and Trichosporon cells is also mentioned. The Examples describe the drying of (1) Candida novellus (2) Candida lipolytica (3) Pichia miso mogii (4) Candida utilis and (5) Bacillus megatherium, each of which had been cultivated upon n-paraffin. According to the procedure of Example 1, 8Kg of dry yeast was mixed with 10Kg of a yeast cell cake having a volatiles content of 72%, that had been obtained by cultivating Candida novellus on n-paraffin containing 5% of iso-paraffin as carbon source, and the mixture was powdered. The powdery mixture was dried for one hour in a fluidized bed at a temperature of 40‹C and the dried product was further heated at 100‹C for 2 hours.

Heading B3W In a rotary punch the drive to a cutter roll 2 carrying a cutting die 2 and an anvil roll 4, which has a resiliently compressible peripheral surface, e.g. of rubber, or comprises a brush roll, includes transmission gears of non-reducible ratio i.e. the products of multiplying the gear teeth of the driving gears and the driven gears respectively have no common denominator in order to spread the cutting wear circumferentially over the anvil roll. The roll shafts 18, 22 are supported in box frames 21 one of which houses the transmission gearing, Fig. 6 not shown, the other housing a cam drive and gears for shifting the anvil roll axially during its rotation to further spread the cutting wear. A cam gear 34, rotatable on the anvil roll shaft 22, is formed in two sections, with comple mentary faces 36, spaced to form a cam groove therebetween. A follower disc 37 keyed to the shaft 22 includes diameterically opposed studs 38 on which rollers 39 are rotatably mounted. The rollers are located in the cam groove so that as the cam gear 34 rotates it shifts the disc 37 and thus the shaft 22 roll 4 axially back and forth. The hubs 44 of the cam gear sections abut shaft bearings 23 to prevent their axial movement. An elongated slot 43 in the shaft 22 in which a driven gear 32 of the transmission gearing keys allows the axial shifting of the shaft. The rotary punch is followed by a stripper unit 6 comprising a roller 7 carrying a knockout punch 8 and a resiliently compressible stripper roller 9 . Both the anvil roll 4 and the roller 9 are associated with a rotating brush 14 for removing waste material from them.

Abstract: 1502590 Mechanical switches COAL INDUSTRY (PATENTS) Ltd 5 Dec 1975 [18 Dec 1974] 54604/74 Heading H1N [Also in Division B7] An electric switch safety device for use, for example, in mining installations where tubs are hauled by a continuously driven rope 25 provides for automatically switching off the winch should a clamp or clip (26, Fig. 3, not shown) holding a tub on to the rope 25 not be released before the end of a run, but is not actuated by rope vibrations below a predetermined amplitude. The device comprises a member 4 biased against a restoring force by a rope or cable 25 to a rest position, a first electric switch 20 arranged to be operated by the rope 25 when it moves to remove the bias from the said member 4, and a second switch 14 having an associated time delay mechanism and arranged for operation by consequential movement of member 4 from its rest position when the said bias is removed. As shown, a pulley 4 rotates on shaft 5 which is urged upwardly by springs 9 but held down by rope 25, and a roller 12 on arm 10 secured to shaft 5 normally depresses a plunger 13 holding switch 14 closed. Switch 20 is in series with switch 14 and is normally closed but can be opened by a pivoted latch 23 acting on a lever 21. Normal vibrations of rope 25, insufficient to lift latch 23, do not result in opening of switch 20 or 14 (due to the time delay action) but if rope 25 lifts latch 23 it opens switch 20. If the rope passes above latch 23 and falls again it will rest on top of latch 23 and cannot bias pulley 4 downwards to prevent switch 14 opening. Thus the winch will be stopped before clip (26) can cause damage.

Excess current through a D.C. load 6 (Fig. 1) in the event of a short circuit therein, is avoided by the arrangement shown, wherein the load 6, is supplied from A.C. mains 1 via a secondary winding 2b, of a a transformer 2 and a rectifier bridge 4. The transformer primary 2a is connected to a controllable converter 3 shunted by an inducter 5 and commutating thyristor 7 and cagacitor 8, The capacitor is charged from an auxiliary R.C. source (not illustrated) to the same polarity as, but higher voltage than, the output of converter 3. Excess current in 6 causes a collapse in load voltage, which is detected by a means not described, which means functions to turn ON Th7. This causes the capacitor voltage to be applied, in opposition to the converter 3 output voltage, to turn OFF the conducting thyristors of the converter so that the transformer Primary current is cut-off and hence also the Secondary current and current to load 6. Simultaneously the control circuit (not described) of converter 3 is changed over to inverter operation mode. The current which was flowing in inductor 5 when Th7 was switched ON continues to flow via C8 and Th7, firstly increasing and then dying away to zero when C8 is discharged, thus causing Th7 to turn OFF.
