Title: Improved apparatus for sorting weeds, stones and the like from potatoes or other crops or vegetables
IPC: B07B13/00
Filed: 1953-04-01
Abstract: 757,994. Separating solid materials. BRICE, A. July 1, 1954 [April 1, 1953; Jan. 22, 1954], Nos. 8994/53 and 1924/54. Class 117. Relates to machines, for sorting potatoes or the like from stones &c., of the type incorporating a smooth rotating surface on to which the mixture is fed and separated by centrifugal force and the different coefficients of friction of the components of the mixture. In the apparatus described, a smooth conical bowl member 1 is rotated by the friction drive 3 and has a central aperture 2. The axis of the bowl is inclined at about 10 degrees to the vertical and its sloping sides include an angle of about 140 degrees. Potatoes, stones, earth, &c., are fed from an elevator 5 to a shoot 4 passing over the upper part of the periphery of the bowl. The potatoes are discharged over a peripheral rubber &c. beading 9 at the lower edge of the bowl and the remainder of the 'material is guided by a deflector 6 to the central aperture 2 for discharge to the ground. The aperture 2 is covered by a dome 7 to minimize the loss of potatoes therethrough. The potatoes are checked by a hanging canvas screen 10 and drop into a trough 11, and as, in practice, a certain number of stones still remain, they are fed to a further separator. This comprises a smooth conical bowl member 20 with an upper rim 21 and an outlet 22 its axis being vertical. The bowl is rotated by shaft 23 which also rotates a smooth distributer disc 28 to which the potatoes and stones are fed by a conical distributer 25 on to which they drop from the trough 11. The member 25 is surrounded by a curtain 29 of loose chain mesh or suspended lengths of chain. Potatoes which drop vertically off member 25 are flung by disc 28 over the rim 21 of bowl 20 or against the upper part of the bowl which discharges them over the rim. The stones, however, slip on disc 28 and fall to the lower part of bowl 20 and slide out of the opening 22. The rim 21 overlaps an annular collecting trough 31 communicating with a shoot 32. The ring 33 forming the bottom of the trough 31 is supported on spring-loaded rollers 34, so that when sufficient weight of potatoes is present it is depressed into contact with, and rotated by, the rim 21 to carry the potatoes to the shoot 32.

Patent GB-950596-A (GB)
Title: Time delay device
IPC: H02H3/08
Filed: 1960-03-15
Abstract: 950,596. Protective cut-out arrangements. McGRAW-EDISON CO. March 15, 1960 [March 19, 1959], No. 9114/60. Heading H2K. [Also in Division H3] In an overload protective arrangement an inverse time delay is provided by a capacitor 29 which is shunted by a rectifier 66 and a resistor 63, the capacitor only being permitted to charge when the voltage drop across the resistor 63 is raised in response to the current in the protected system 20 reaching a predetermined minimum value. In the arrangement shown in Fig. 2, the current derived from a current transformer 22 and rectified by a rectifier 24 causes transistors 75 and 76 to conduct, so causing a junction point F to have a potential proportional to the system current. When this potential exceeds the fixed potential of a junction point G determined by a Zener diode 72, a transistor 70 conducts and causes a further transistor 94 in series with the resistor 63 to conduct. This increases the voltage drop across the resistor 63 which prevents the flow of current through the rectifier 66 and permits the charging of the capacitor 29 through a resistor 36, transistor 40 and a resistor 47. As the capacitor 29 charges, the voltage at a junction point D rises causing the emitter currents of transistors 100, 101 to rise, with the result that the potential at point M connected to the base of a transistor 98 rises. The potential at the emitter of this transistor is maintained constant by a Zener diode 110 so that when the capacitor 29 has charged sufficiently for the potential at point M to exceed that at point P, the transistor 98 conducts causing the energizing of the relay 120 and the tripping of a main circuit-breaker 130. The power supply for the transistors and the relay may be derived from a battery, or as shown from a capacitor 30 which is charged from the current transformer to a potential determined by a transistor 44 and a Zener diode 45. The inverse time delay characteristics of the arrangement may be varied by altering the values of series resistor 47, shunt resistor 48 and the capacitor 29 as in the automatic reclosing circuit-breaker arrangement of Fig. 10 in which a number of rapid tripping operations are followed by a number of slower tripping operations before lock-out occurs. In this arrangement a known hydraulic counting arrangement 172 moves a bar 214 step-by-step on successive closing operations of the circuit-breaker 130, the movement of the bar controlling the operation of switches 224 to connect or disconnect an additional capacitor 229 and additional resistors 247 and 248 to vary the time delay. Lock-out is effected when an arm 260 on the bar 214 releases a lock-out switch 174 to open contacts 186 in series with the closing coil 176 of the circuit-breaker.

Abstract: 1,154,997. Differential gear control. DAIMLER-BENZ A.G. 26 Feb., 1968 [3 March, 1967], No. 9174/68. Heading F2D. A manually controlled hydraulically or pneumatically engaged clutch 15 for positively locking a motor-vehicle differential 12 for cross-country use is automatically overridden by a speed-responsive fluid pressure relief valve 24 permitting clutch release, via a spring 19, to re-establish differential action of the gear for normal road use. As shown. the positive clutch 15 is controlled via a pivoted lever 17 connected to a piston 18 moved for clutch engagement to lock the differential for cross-country use, when fluid pressure is supplied from a reservoir 20, charged by a pump 21, by a manually operated valve 23 via the pressure release valve 24, which valve is electromagnetically controlled by a winding 25 connected to a contact 26 in the vehicle speedometer such that on increase of the vehicle speed on normal paved roads (e.g. when the speed reaches a figure of say 40 k.p.h. corresponding to the position of the speedometer contact 26), the pressure release valve 24 is opened to override the manual valve 23, viz. releasing the fluid pressure via duct 27, whereby the spring 19 returns the piston 18 to disengage the clutch 15 for normal differential action, an indicating lamp (not shown) warning the driver to turn off the manual valve 23.

Filed: 1951-04-24
Abstract: 680,195. Measuring heat quantities. NAAMLOOZE VENNOOTSCHAP PROVINCIAAL EN GEMEEN-TELIJK UTRECHTS STROOMLEVERINGSBEDRIJF. April 24, 1951 [April 28, 1951],. No. 9509/51. Class 97 (iii). [Also in Group XIX] A heat consumption meter for a flowing fluid is provided with a flow-meter driving a toothed cylinder, the number of tooth of which varies in axial direction, co-operating with a toothed wheel which is axially slidable on a shaft driving a counting mechanism and is shifted by a pivotal lever having a fixed fulcrum loosely engaging the slidable toothed wheel, a floating lever being pivoted to the pivotal lever and being coupled at each end to a Bourdon tube thermometer. The shaft 2 of a continuous flow type water meter 1 drives, through a gear 3; a stepped toothed cylinder 4, whose shaft carries a gear 5 actuating counting mechanism 6 to indicate the quantity of water flowing in a heating plant. Each of two Bourdon tubes 7, 8 forms part of a thermometer the temperature feelers of which are placed in the forward flow of hot water and return flow of cooled water respectively. Pivotally connected to the free end of each Bourdon tube is a link 9, 10, each of which is pivotally mounted on a pin 12 secured to a lever arm 14 rigidly secured on a shaft 13 which carries a lever arm 15 engaging with its forked end 19 the chamfered hub 18 of a toothed wheel 16 slidably mounted on a square shaft 17 and adapted to be driven by the cylinder 4 and to drive a counter 21 through gear 20. The thermometers and Bourdon tubes 7, 8 are filled with mercury at high pressure, e.g. 150 atmospheres. The Bourdon tubes are preferably of equal size and shape and so mounted that their free ends move along parallel lines a, b upon changes of temperature so that with the linkwork suitably adjusted and the number of teeth on the cylinder suitably graded, the displacement of the wheel 16 will be linearly proportional to the temperature difference and the counter 21 will indicate the quantity of heat consumed in the plant. The extent of displacement of the wheel 16 may be varied by adjusting the pivot 12 of the floating lever 11 in a slot of the arm 14 whereby the active length of the arm is varied. As shown, the number of teeth on the lower part of the cylinder 4 is constant so that a constant minimum quantity of heat independent of the temperature differential is registered by the counter 21, e.g. this may apply for differentials below 20‹ C. Where there are no teeth the cylinder should be of smaller radius than it is between teeth to avoid driving by friction. In a modification, the forked end 19 of lever 15 is formed separately and is pivoted on a block 22 which is pivoted on the lever 15 so that the fork 19 pivots about two axes at right angles. Double tariff counting mechanism may be provided, e.g. for day and night, comprising two counting mechanisms alternately driven through differential gear controlled by a relay excited by a time switch.

Title: A process for the production of cyanuric acid
Inventor: CLAREN OTTO BERND
IPC: C07D/
Filed: 1961-03-16
Abstract: Cyanuric acid is prepared by heating urea in the presence of a solvent consisting of a mono- or di-hydric alcohol which contains no ether groups and has a boiling point above 170 DEG C., preferably between 200 DEG C. and 300 DEG C.  Suitable alcohols are 1,4-butane-diol, 1,6-hexane-diol, n-octyl alcohol, and n-nonyl alcohol.  The cyanuric acid produced as a fine powder may be separated by, for example, suction filtration or centrifugation.  In the Example 300 parts of n-octyl alcohol are heated with 200 parts of urea.  A homogeneous solution forms at 130 DEG C. and evolution of ammonia begins at 170 DEG C.  The boiling point of n-octyl alcohol (usually 194 DEG C.) rises under the reaction conditions to about 235 DEG C.  The precipitated acid is suction filtered and washed with a little methanol, and the whole process is then repeated six times, 200 parts of urea being added each time to the same alcohol.  The yield of cyanuric acid is 95% of the theoretical yield.  The Specification also contains a review of prior art processes in which cyanuric acid is prepared by heating urea in the presence of phenols, ether alcohols, acid amides, sulphuric acid, diphenyl, and fused tin.

Filed: 1975-03-07
Abstract: 1500551 Data transmission; monitoring arrangement INTERNATIONAL STANDARD ELECTRIC CORP 7 March 1975 [8 March 1974] 9625/75 Heading H4P A plurality of clock pulse units supply, through lines respective to the units, groups of equipment and each group has a change-over circuit which selects the other supply on failure of the supply being utilized. The lines may loop through the various pieces of equipment and be connected to a further monitor at the far end. As shown two clock pulse supplies TG1, TG2 are connected through decade scalers Z1, Z2 and respective inhibit gates SP1, SP2 to lines st1 and st2 which loop through the various pieces of equipment E 1-EN and back to a monitoring circuit UA1. Each piece of equipment comprises a monitoring and change-over circuit (Fig. 2] which changes to the other supply when a monitor CO1 detects that the first has become faulty. The selected output also feeds a monitor (US1) which detects the absence of pulses and a unit US2 which detects a discrepancy in the ratio of the pulse rates of that of a further supply (ot 1 or ot2 of Fig. 1). The ends of the loops st1 and st2 are applied to the up and down count terminals respectively of a counter UA1 which receives input from the pulse sources so that if the pulse rate of one source is higher than the other the counter counts to b1 and gives a first alarm Al and if it ceases altogether it counts to aI and gives a second alarm Al. UA1 also operates gates SP1 and SP2. Likewise if the other is of lower frequency or ceases the counter counts to cl and d1 to give alarms and effect changeover. The clock supplies TG and TG2 are, in addition, counted down in scalers TU1 and TU2 and similarly applied to further equipment such as for call metering.
