Title: Improvements in or relating to the coating of seeds
Inventor: GRIMM HANS
IPC: A01C1/06
Filed: 1962-12-18
Abstract: To facilitate uniform sowing of seeds and their germination in an environment, e.g. wet soil, deficient in atmospheric oxygen, the seeds, such as monogerm beetroot and sugar-beet seeds, are coated, e.g. at 4 DEG C., with a coating comprising one or more hydrophobic metal compounds and one or more autoxidisable compounds, which coating is rendered temporarily and/or locally alkaline, either before, during or after application to the seeds, by the application of one or more alkaline compounds, in the presence of oxygen or one or more oxidising agents, to effect autoxidation of the autoxidisable compound or compounds. Specified hydrophobic metal compounds are: ferric oxide, zinc oxide, red lead oxide Pb3O4, lead dioxide, chromium oxide Cr2O3, calcium stearate or palmitate and magnesium stearate or palmitate.  Specified autoxidisable compounds are: pyrocatechol, resorcinol, pyrogallol and tannin. Specified alkaline compounds, which may function as binders and fertilizers are: lime, potash, water-glass and ground basic slag. Specified oxidising agents are: air, hydrogen peroxide and inorganic per acids or salts, such as sodium perborate and pernitrous acid.  The seeds may be coated in the presence of an aqueous solution of a non-electrolyte such as sugar, which solution may contain a wetting agent such as soap and a dye such as eosin.  After autoxidation has been effected, the pH of the coating may be reduced to a value between 6.5 and 8.0, as by adding an acid or acidic substance such as peat.  An agent which promotes germination such as an inorganic nitrate (including ammonium nitrate) and a bacterial concentrate such as Bacterium herbicola may be included in the coating.

Title: Spring-applied brake actuator
IPC: B60T17/08
Filed: 1973-10-18
Abstract: 1442834 Spring-applied actuators; transmitting mechanisms WESTINGHOUSE BREMSEN UND APPARATEBAU GmbH 18 Oct 1973 [19 Oct 1972] 48709/73 Headings F2E and F2F A piston 4 of a vehicle brake actuator is movable under the action of a spring 7 to pull the core 14 of a Bowden cable and cause application of a brake; release of the brake may be effected by the manual release of a locking device arranged between the piston 7 and the core 14. In the embodiment of Fig. 1, a threaded pin 17 at the end of the cable core 14 is retained by a nut 18 in a threaded hole 19 of a locking sleeve 21 which is arranged to be locked in a tube 22 firmly connected with the piton 4. To this end an internal groove 23 running round tube 22 holds locking balls 24 in radial holes 25 in the sleeve 21 on a tubular shoulder 26 of a shoulder locking pin 27, the shaft 30 of which leads outside the actuator. The guide tube 22 is movable in a guide 29 fitted in an end wall 31 of the actuator housing 3. In the event of a desired or undesired fall of pressure in a pressure chamber 2, the spring 7 moves the piston 4 to the right, taking the tube 22 and the locked locking sleeve 21 with it and pulling the core 14 which is fixed to a brake lever. To release the brake manually without the application of fluid pressure to chamber 2 the operator strikes the shaft 30 and when the tubular shoulder 26 passes the drillings 25 the locking balls 25 are released and the locking sleeve 21 is pulled toward the left by the tension in cable core 14, and the brake is thus released. When pressure acts once again on the piston 4 the device is automatically locked. In the embodiment of Figs. 2, 3 the tube 122 connected to piston 104 carries a profile ring 133 equipped with internal grooves 134, 135 adjacent one of which is a stop 136. A reduced diameter part 138 of a locking bar 142 provided with guide cams 139, 141 extends into the ring 133 and the threaded pin 117 of the Bowden cable core 114 is attached inside the reduced part 138. To release the brake manually a rotary movement is applied to the bar 142 until the guide cams 139, 141 are over the grooves 134, 135, whereupon the cable core 114 pulls the bar 142 through the ring 133. To relock the device the piston 104 is acted upon by pressure and the tube 122 and ring 133 are thereby moved leftwards. When the cams 139, 141 are free from grooves 134, 135 a torsion spring moves the bar 142 to a locked position.

Title: Improvements relating to apparatus for feeding materials to packaging machines
IPC: B65B1/08
Filed: 1966-11-07
Abstract: 1,112,740. Weighing apparatus. S. B. BLODGETT. Nov. 7, 1966 [Nov. 5, 1965], No. 49811/66. Heading G1W. Apparatus for feeding material to a packaging machine, operating in cycles during each of which there is an available feed time during which the packaging machine can accept the material being fed, operates in synchronism with the packaging machine during each cycle for an actual feed time which starts with the beginning of the available feed time and which is terminated when a predetermined weight of material has been fed to the packaging machine, and means is provided for subtracting a first signal generated by the feed apparatus and representative of the actual feed time from a second signal representative of the available feed time to produce a third signal which operates a device to adjust the feedrate so that the first signal approaches the second signal. The material to be packed, e. g. potato chips, pretzels, coffee, &c., is supplied via a shoot 50 to a conveyer 51 and a vibrating feeder pan 57 to a dump bucket 72. A signal 69 representing the actual weight of material in the bucket 72 as measured by the scale 67 is fed continuously until a preset weight is received in the bucket 72, to a relay 62. From the latter a signal 69' is transmitted to a synchronous motor unit 21 to engage a clutch 23 and release a brake 24 so that the motor 22 drives a gear 30' meshing with a gear 31 rigidly connected to a bevel gear 32, which thus rotates in each cycle for the duration of the actual feed time. A signal 15 indicating the available feed time is transmitted from the packaging machine 11 via a cam operated switch 16 to a synchronous motor unit 25 to engage a clutch 27 and disengage a brake 29 so that the motor 26 drives a gear 39' meshing with a gear 33 rigidly secured to a bevel gear 41, which is thus driven in each cycle for the duration of the available feed time. The gears 32, 41 rotate in opposite directions and engage a differential bevel pinion 34 which merely rotates about its axis when both gears 32, 41 are rotating. If, however, one of the gears 32, 41 continues to rotate after the other has ceased turning the differential pinion 34 rolls on the rotating gear 32 or 41 and causes a stub shaft 35 to turn a shaft 37 to generate and electrical signal in a device 42 to change the feeding rate to maintain the actual feed time approximately equal to the available feed time.

Filed: 1966-11-09
Abstract: 1,166,531. Shearing. WESTERN ELECTRIC CO. Inc. 9 Nov., 1966 [9 Nov., 1965], No. 50150/66. Heading B3W. A method of cutting, by hydraulic pressure, articles having portions offering different resistances to cutting, comprises the steps of placing the portions to be cut between a female die and a source of hydraulic power and increasing the hydraulic pressure while applying support pressure to the said portions, such that simultaneous cutting of all said portions occurs. An apparatus for carrying out the method comprises a pair of die blocks 14 and 15 having die cavities 16 and 17, the blocks each defining two sides of a rectangular opening to receive a waveguide 10. In the die cavities are plates 30, 32 which have slotted inter-engaging corners so that the waveguide is supported externally all round its periphery. The plates are supported by springs 36, the tension of which is adjusted by screws 38 to suit the material being cut. A mandrel 22 which is inserted in the waveguide has a peripheral groove which is positioned opposite the die cavities 16 and 17. A composite nylon and rubber seal is provided in the groove to engage the inner walls of the waveguide. A bore 24 in the mandrel communicates with the peripheral groove by transverse conduits and receives a plunger 28 which is forced into the bore to increase the fluid pressure in the peripheral groove. As the pressure increases the material tends to deform and shear at the regions 59 near the middle of the flat faces, but these regions are supported by the plates 30 and 32 so that the pressure continues to increase until it is sufficient to shear the corners 61. For any particular material the pressure of the springs 36 is adjusted so that the plates do not withdraw until the fluid pressure is sufficient to shear the strongest part of the article to be cut.

Title: Method and apparatus for equalizing tensions of sub-tows
IPC: D01D10/04
Filed: 1967-11-06
Abstract: 1,211,022. Filament tension equalizing apparatus. TEIJIN Ltd. 6 Nov., 1967 [5 Nov., 1966], No. 50415/67. Heading B5B. [Also in Divisions D1-D2] In a method of equalizing the tensions of subtows of synthetic thermoplastic filaments having different tensions and running along parallel paths before they are gathered into a single tow which may then be drawn, each sub-tow is subjected to a particular resistance by a particular degree of deflection from its path of travel such that the tensions of the sub-tows thereafter are equal. As shown, sub-tows 1 removed from cans 2 are guided in parallel relationship by hooks 3 fitted to rods 4, or by rollers (not shown), and then, in passing between additional guides 6 and 7, are individually deflected by rings 9 of guides 10 each adjustably positioned on a support rod 8 so as to cause a required degree of deflection in inverse relation to each associated sub-tow tension. Guides 10 may be replaced by a single plate (12) providing a row of holes for separate guidance of the sub-tows and pivotally mounted on a support 5 so that the angle formed between the plate and a horizontal plane may be adjustably varied by movement of a hand wheel transmitting through worm gearing. In examples, 30 sub-tows of undrawn polyethylene terephthalate filaments are gathered into one tow by means of the apparatus of Fig. 1, and then drawn in hot water or steam, crimped by stuffing and heat-relaxed.
