Abstract: 1393235 Endless belt conveyers MATO MASCHINEN - UND METALLWARENFABRIK CURT MATTHAEI GmbH & CO KG 30 July 1973 [31 July 1972] 36222/73 Heading B8A The ends 2, 3, of a conveyer belt are drawn together by applying tension to cables 4 which are connected to bars 5, 6, between which the belt is gripped, the cables 4 applying gripping pressure to the bars 5, 6, by the action of a cam-like mechanism. Each cable 4 which may be disposed at an angle as shown in Fig. la, or may be parallel with the belt as shown in Fig. 1b, passes around a goove in the periphery of a cam-like member 12 and is secured to the body of the member 12 at 16. The latter is pivotally mounted at 11 on lugs 9 which are rigid with a sleeve 7 carried by the bar 6. A lever arm portion 17 of the member 12 is pivotally connected at 18 to a sleeve 8 carried by the bar 5. Thus when the cable 4 is tensioned, the bars 5, 6, are drawn together. The plane of the member 12 may, as shown in Fig. 2, be disposed at an angle to the direction of conveyance. Alternatively, the sleeves 7, 8 may be rotationally displaceable so that the member 12 may be self-aligning.

Title: Improvements in connection with the mowing, brushing, and pricking of lawns and the like
IPC: A01B1/24
Filed: 1934-12-21
Abstract: 433,255. Mowing, brushing, and pricking lawns. DRONSFIELD BROS., Ltd., and DRONSFIELD, S. W., Atlas Works, Oldham. Dec. 21, 1934, No. 36654. [Classes 6 (i) and 6 (ii)] Apparatus for treating lawns and other grassed land and adapted to be used alternatively as a lawn-mower, a pricking and aerating apparatus, or a brushing-machine, is provided with means for detachably mounting a pricking-roller or a rotary brushing-device to operate in lieu of the detachable grass cutter cylinder, whereby a triple-purpose apparatus of similar nature to a lawn mower is produced. The rotary mowing-cutter C, Fig. 1, is mounted on a stationary spindle a, which is removably mounted on a pintle f, Fig. 4, at one end and an adjustable screw g, with locking-device g<1>, at the other end, Fig. 4 showing the spindle a replaced by another removable spindle a<1> on which is mounted a rotary brush B adapted to be driven in place of the cutter by the usual gearing of the lawn mower. The usual delivery plate D, Fig. 1, with ledger blade D<2> is secured to a removable spindle D<1>, Fig. 4, mounted on a pintle f and an adjustable screw g, the latter being mounted in an eccentric bush to provide for slight adjustments of the ledger blade. When the rotary cutter is replaced by the brush B, a light delivery plate P is mounted on the spindle D<1> instead of the mower delivery plate D, and may be adjusted by the same screws p<1> which serve to adjust the delivery plate D. In order to effect aeration by pricking, the cutter or brush is removed, and a pricking-cylinder furnished with spikes is mounted on another removable spindle, and is rotated by forward movement of the machine. The cutter, brush, and pricker are adjusted relatively to the ground by the usual forward roller, the spindle 1 of which is carried by slotted brackets 2 adjusted by rack and pinion gear 3, 4.

Patent GB-816794-A (GB)
Title: Improvements in or relating to apparatus for drying culture media and the like
IPC: F26B17/02
Filed: 1955-12-21
Abstract: <PICT:0816794/III/1> In apparatus, for dyring culture media and heat-sensitive food products, wherein the material is spread as a film of a moving endless belt 10 and the film is heated by elements 22 which emit radiant energy, adjustable shutters 30 are mounted between the radiators and the belt to regulate the amount of radiant energy reaching the belt.  The shutters 30 comprise metal slats mounted on oscillatable rods 31.  In the inclined position these slats reflect radiant energy away from the faces of the belt to a degree dependent upon their inclination from the vertical.  The belt, which may be made of stainless steel, is mounted on pulleys 11, 12; and pulley 11 is rotated in the direction shown by a source of power (not shown).  The belt is enclosed in a housing 35 which is evacuated through a pipe 36 connected to a vacuum pump. The material to be dried is supplied to the belt from receptacle 17 by roll 20.  The radiant elements comprise chambers 23 through which a heat-transfer liquid of the chlorinated bi-phenyl type is circulated by pipes 24, 27.  Pulley 12 has a hollow shaft which is connected by pipes 15, 16 to a peripheral compartment 13 through which cold water is circulated, whereby the dried product is cooled.  The cooled product is scraped off the belt blade 38, and collected in one or other of the two containers 43.  Piping 44, controlled by valves 45, is adapted to supply an inert gas, such as nitrogen, to fittings 42 whereby the vacuum below valves 41 can be broken after a container has been filled.  The slats 30 may be individually adjustable, but they are preferably interconnected in sets of two or more.  In order to achieve any desired differences of radiation intensity at various points on the belt, the effect of the shutters may be supplemented by contructing or arranging the radiators in a stepped configuration, or inclined to the belt, so that the spacing of the radiators from the belt differs as between the various points where such different radiation intensities are required.  Likewise, the radiators may be divided into sections each fed by heating-liquid at different temperature, or fed in cascade to provide a temperature-gradient over the extent of the radiators.  The water-vapour resulting from the drying may be removed from the housing by the employment of steam-jets, by absorption by silica gel, by freezing on refrigerated surfaces, or by condensation by sprays of refrigerated lithium chloride solution.

Title: Method for determining the viability of seeds prior to their  germination
IPC: A01C1/02
Filed: 1974-08-27
Abstract: 1471076 Measuring viability of seeds electrically SENSORS Inc 27 Aug 1974 37452/74 Heading G1N The viability of seeds is determined by applying a potential to each seed and measuring the current passing therethrough. Seeds in a dry state are first moistened for a period of time and at a temperature sufficient to cause the seeds to pass from the dry state into at least the first phase, inhibition, of their pre-germination cycle but without initiating the last phase, ribonuclease synthesis, of the cycle. Each seed is then placed between a pair of steel electrodes to which a potential of about 1À5V is applied, or a pair of dissimilar metal electrodes generating their own voltage, and the current flowing through the seed measured. After an initial maximum the current decays to a steady state, either the maximum or steady state current being used to indicate the viability. After testing the seeds are returned to their dry state and stored. Calibration. Measurements as above are carried out on each kind of or brand of seeds and instead of returning the seeds to their dry state the germination cycle of each of the seeds is completed for a predetermined time to produce a seed radicle. The lengths of each of the radicles is measured and correlated with the corresponding measured current. Alternatively the seeds may be dried and then planted in soil for a predetermined period to allow at least some of the plants to emerge. The plant heights are then measured and these with the soil emergence levels are correlated with the corresponding measuring currents. Tests have shown that higher levels of currents are commensurate with lower levels of germination, radicle height and plant height, i.e. viability of the seeds. Thus after the calibration testing of seeds of the same type may be carried out and those which show a current less than a predetermined level, chosen by the calibration, are rejected. Various graphs and tables correlating current and viability are given.
