Title: Improvements in or relating to an implement for harvesting beets or the like root vegetables
IPC: A01D25/04
Filed: 1956-11-06
Abstract: 848,938. Root crop harvesters. VAN DER LELY N. V., C. Nov. 6, 1956 [Nov. 7, 1955], No. 33868/56. Class 6(3). An implement for harvesting beets and other root crops comprises members for engaging the roots and rotating them about their longitudinal axes while they are still in the ground, for the purpose of loosening them and removing excess soil therefrom. As illustrated in Fig. 1, one of the crop-engaging members comprises an endless belt 26, driven via the transmission shaft 32 from the power take-off of the the traction vehicle, and supported by a beam 21A rigidly fixed to the frame 7 of the implement. The second member comprises a bar 38 pivotally mounted on a beam 37, which is in turn pivotally mounted on the frame 7, the two members being urged together by draw springs 40. That run of the belt 26 which is adjacent the bar 38 moves in the direction opposite the direction of advancement of the harvester, and its speed relative to that of the harvester is so adjusted that the roots engaged between the members 26 and 38 are rotated about their longitudinal axes without being moved in a direction transverse to those axes. The members 26 and 38 are inclined to the horizontal, thereby exerting a lifting force on the roots and removing them from the soil. The roots are dropped on to the ground when they reach the rear ends of the members 26 and 38 and are then picked up and deposited behind the harvester by the conveyer 45. The arrangement may be modified by providing a second endless belt in place of the bar 38 and arranging for the run adjacent the belt 26 to move rearwardly at a speed which is different from that of the belt 26. The harvester may alternatively be modified by substituting two powerdriven wheels 96 for the members 26 and 38, and by providing wheels 111 for the purpose of lifting the roots on to a conveyer 115, the wheels 111 being inclined to the vertical, and either being freely rotatable so as to be rotated by their contact with the ground as the harvester advances, or being driven. This latter modification forms the subject of Specification 848,939.

Title: Improvements in or relating to envelope making machines
IPC: B31B19/00
Filed: 1935-12-07
Abstract: 467,097. Feeding sheets. DICKINSON & CO., Ltd., J. Dec. 7, 1935, No. 33982. Convention date, Dec. 7, 1934. [Class 100 (i)] [Also in Group XVII] The rotatable separator discs of the feeding mechanism described in Specification 375,025 are each provided with a series of circular grooves 39 on their operative faces to reduce the frictional drag between the discs and the stack of envelope blanks. A suction device 71, operated through a lever 71a initiates the feed of the bottom blank from the pile A by engaging the forward portion of the lowermost blank and separating the same from the stack. The suction is then cut off and a pair of daggers 73 move to engage the upper face of the blank and press it against the conveyer 74. Simultaneously, shovel-like members 53, 54, extending along top and bottom faces of the separator discs 10, 11 move forward, the function of the members 53, 54 being to prevent the horns 52 of the separator discs from coming into contact with the window apertures of the blanks. Rollers 75 now move forward and the lifter 62 is actuated so that a roller 69 lifts slightly the rear end of the stack A. The sucker 71 is now withdrawn and the horns 52 of the discs 10, 1.1 enter between the partly separated blank and the stack to support the stack while the conveyer carries off the separated blank. A portion of the weight of the stack is taken by a finger at the front of the pile, and the stack is maintained against movement by adjustable stops 40, 47, 49a, the stops 40 being adapted to project into the grooves 39 positioned between ridges 38 formed on the separator discs. The distance between the axes 19 of the discs 10, 11 may be varied by the manipulation of links 17, 18, pivoted at 22, and carrying sprockets and chains always in driving connection. Bolts 36 permit of maintaining the adjustable links 17, 18 in any desired position. The separated blanks arranged in a band, with sealing flaps only exposed, are passed by belts 74, 78 to a drum 80, gum being applied to the flaps by a device 81, 82. A reciprocating suction device 86 working in co-operation with oscillating daggers 89 remove the gummed blanks to the grippers 83 of a drying chain 84 moving slightly faster than the drum 80.

Abstract: 919,900. Frequency discriminators. RIBLET, H. J. Oct. 4, 1960 [Oct. 5, 1959], No. 34052/60. Class 40 (5). A tunable microwave frequency discriminator is formed by a pair of contiguous waveguide sections 2, 3, hybrid coupled by a short slot 5 of length d about equal to one free space wavelength at the operating frequency, with one input 12, and two outputs 13, 15 each give equal outputs of TE 10  and TE 20  microwave energy modes to a pair of detectors 16, 17. The outputs of TE 10  mode are equal in phase but of TE 20  mode are opposite in phase and 90 degrees differing in phase from the TE 10  mode at the operating frequency. A matched termination 14 absorbs all energy reflected backwards to it. Further, a tunable cavity resonator is coupled to either the TE 10  or TE 20  mode by a longitudinal or cross-slot 9 respectively, just above the slot 5, with the latter junction, or differentially to both modes depending on the orientation of the slot 9, and for frequency variations the relative phases of the TE 10  and TE 20  waves combined at the detectors (of opposite polarities) varies to give a differential output dependent on the magnitude and sign of the deviation. Inductive indentations 8, by reducing the waveguide width below 3#/2 and a capacitive button 6, prevent any TE 30  mode arising. The detector inputs may first be amplified by travelling wave or other amplifiers. The discriminator output may stabilize the frequency of a klystron or backward wave oscillator by a D.C. feed-back loop.
