Title: A method and machine for the treatment of sugar or fodder beet seed clusters
Inventor: HARMOS FERENC
IPC: A01C1/00
Filed: 1958-07-29
Abstract: 881,844. Treating beet seeds. AGRIMPEX MEZOGAZDASAGI KULKERESKEDELMI VALLALAT. July 29, 1958, No. 24463/58. Class 58. In treating sugar- or fodder-beet seed clusters, particularly polyploids, to improve the germinating power, the clusters are rubbed against each other, under their own weight, to effect removal of their outer integuments and associated bacteria, parasites, eggs thereof and weed seeds. The clusters, e.g. together with an abrasive subtance such as quartz sand, are fed into a container 1, having an upper cylindrical part and a lower frustoconical part 4, and are agitated by blades 3 secured to a rotating shaft 2, e.g. at a pitch so as to propel the seeds downwards. The seeds are discharged through openings 6 in the base 5 and a turnably adjustable plate 7. Powder produced during agitation may be drawn off by suction. The treated seeds may be subjected to sieving or screening to isolate single seeds, double seeds and larger clusters and any abrasive substance present.

Title: Water control mechanism for automatic washing machines
IPC: D06F34/08
Filed: 1946-08-16
Abstract: 622,485. Washing-machines. TRIGGS, W. W. (Bendix Home Appliances, Inc.). Aug. 16, 1946, No. 24479. [Class 138 (ii)] In an automatic washing machine, during the time an electromagnetic water valve 23 or 24 is operated to fill a tub 11 with water, a sequence timer drive motor 17 is interrupted by a snap-action switch 29 controlled by a water level responsive mechanism 27 which closes the switch 29 at a predetermined water level; the timer motor being energized while a drain valve 31 is open by a second snap-action switch 33 in a separate circuit, the arrangement being such that a closed circuit for the timing motor is provided at all times except when the water is being admitted. Mechanism.-A perforated, horizontallymounted drum 10, Fig. 2, is contained in the tub 11 and is belt driven by an electric motor 14 through a two-speed gear-box 13 controlled by a solenoid 25 and giving a low-speed rotation for washing and a high-speed for drying. Water control means.-Hot and cold water is fed to a mixing valve 21 which is controlled by a hot-water solenoid 23 and a thermostaticallycontrolled mixed water solenoid 24 (not shown). The draining assembly, Fig. 3, comprises a continuously operated drain pump 30 driven by the motor 12 and connecting it to the tub 11, a valve 31 controlled by a solenoid 32. The switch 33 is linked to the solenoid 32 so that it is closed when the drain valve is open. A float 27, Fig. 2, in the tub operates two linked switches 28, 29. Switch 28 is in the circuit of the water solenoids 23, 24 and is closed when the tub is empty and opened when it is full. Switch 29 is in a timing motor circuit in parallel with the drain-operated switch 33 and operates in the reverse order to switch 28. Operation.-the solenoids are all controlled by the sequence timer 16 which is driven by a synchronous motor 17 and comprises four cams 1-4, Fig. 5, controlling switches 1A, 2A, 2B, 3A, 3B, 4A. Switch 1A breaks the electric supply circuit; switches 2A, 2B control the drum and hot water solenoids; switches 3A, 3B control the mixed water and motor speed solenoids and switch 4A short-circuits float switch 28 at one part of the sequence. The operation must be started manually by moving the cams until switch 1A makes contact, the timing motor is then able to take over control, but does not run until the tub is full of water, since its circuit is broken by switch 29. When the tub is full, the soak-agitate period is commenced as shown in Fig. 6. At the end of this period the operation of cam 1 stops the machine which must be restarted manually to start the remainder of the cycle comprising washing, rinsing and drying periods as shown in Fig. 6. Whenever the tub is filling with water, the timing motor is stopped, since the drain switch 33 and the water-level switch 29 are open. When the tub is being emptied, the drain switch 33 is closed and so the timing motor runs. When the tub is full, switch 29 is closed. Specification 514,887 is referred to.

Rotary mixers.-A concrete mixer of the conical, tilting drum type is provided with automatic means for operating the charging skip, supplying a measured quantity of water, and tilting the drum to its charging and discharging positions at the beginning and end of the mixing operation. For this purpose a shaft 17, Fig. 8, driven from the prime mover, drives a screwed shaft 58 through a clutch 61 and direct and reverse trains of gearing 56, 60, and 49, 62, 59; the gears 49 and 50 are on a, sleeve 51 clutched to the shaft 17 by a hand-operated clutch 52. The screwed shaft 58 operates a slider 72 having a sleeve member 76 surrounding a rod 70 and provided with a projection 87 engaging a catch 85 on a second rod 80 connected with a clutch 45 operating the winding-gear for the charging skip and with a brake 93. As the slider 72 moves to the left, a projection 77 thereon engages a fork 90 which, through a rod 91 and lever connections, operates a three-way valve 92 connecting the measuring tank with the mixing drum and main alternately. The projection 77 then engages an arm 82 operating the link 80 which throws the clutch 45 into operation to raise the charging skip. The sleeve 76 then engages a spring-mounted collar 78 thus moving the rod 70 and operating, through a bell-crank 69, link 68, and snap-over lever 66, a slider 63 controlling the clutch 61; by these means, the rotation of the shaft 58 is reversed and the slider moves to the right. The projection 87 thereon engages the catch 85 and moves the rod 80 to disengage the winch clutch 45 and apply the brake 93 controlling the lowering movement of the changing skip; the catch 85 is thrown out of engagement by a fixed pin 88. An adjustable stop 75 on the slider then engages a second spring-mounted collar 79 and moves the rod 70 thus effecting a second actuation of the clutch 61 to reverse the rotation of the shaft 58; the movement of the slider 63 operates a striker 94 which sounds a gong indicating the end of the mixing operation. The movements of the rod 70 operate an arm 35 on a shaft 30 which, as shown in Fig. 5, operates a pair of yokes 29 controlling clutches on a pair of bevel gears on a constantlydriven shaft and in mesh with a bevel on a worm shaft 22 which tilts the yoke F in which the mixing-drum is mounted. The clutches are automaticall thrown out of gear by the engagement of cams 32 in the worm wheel 20 with arms 31 on the control shaft 30 at the ends of the tilting movements of the mixing-drum.
