Title: Beet lifting and topping implement
IPC: A01D27/04
Filed: 1943-11-02
Abstract: 571,086. Beet harvesters. LOUCKS, C. A., and SCHMIDT, L. K. Nov. 2, 1943, No. 18151. Con-. vention date, April 16. [Classes 6 (i) and 6 (iii)] A beet harvesting machine comprises a spiked wheel 16 upon which the beets are impaled and lifted from the ground, and a sub-soil plough 21 positioned below and slightly to the rear of the ground-engaging portion of the wheel, the plough and wheel being mounted on a frame 10 which can swing up and down about an axis - adjacent its forward end, and means being provided to remove the impaled beets from the spikes 19 of the wheel. The machine shown comprises a main frame 1, having a rear cross beam 4 and side beams 2 converging, forwardly towards a draft tongue 5 for connection to a tractor drawbar 6. Upon frame 1 is pivoted for vertical swinging movement about its forward end a frame 9, shown in its raised position in Fig. :2, the rear end of frame 9 being mounted between arcuate guide beams 14. Frame 9 can be raised or lowered by a winch driven by an engine 61 and is resiliently suspended by springs 'connected to chains depending from a frame 13 upstanding from main frame 1. Wheel 16 is journalled in frame 9 and is driven by engine 61 so that, when the frame is lowered, it travels over the beets and impales them. The beets are carried ,around the wheel on rows of spikes 19 until they meet a topping device carried by a frame 32 upstanding from frame 9. As shown in Fig. 4, the topping device comprises sets of fingers 35 fixedly mounted on an adjustable shaft 34 and projecting tangentially to wheel 16 between the rows of spikes 19. The fingers are fitted with topping knives 36, also projecting between the spikes in a position determined by the adjustment given to shaft 34. The beets are fed to a tumbling conveyor disposed between side walls 40 and comprising a number of rotating shafts, each carrying a number of wheels 42 fitted with curved fingers 42a. Earth thus loosened falls on to a transverse discharge conveyor 60 while the beets pass into a hopper 47, which feeds them to an endless upwardly and outwardly inclined conveyor 49 adapted to discharge into a truck. Conveyor 49 has its upper portion hinged to the lower portion, whereby it may be folded to be across the machine when not in use. The beet tops are removed from the spikes by spring- controlled pivoted bars 55, Fig. 6, extending between the rows of spikes. Each bar has a deflector plate 58, whereby the tops are discharged on to the conveyor 60. The plough 21 is carried by a member 20 which is so connected to frame 9 that its longitudinal position and its angular inclination with respect thereto can be adjusted. As shown in Fig. 12 the plough may consist of a member 85 fitted with longitudinally extending ground-cutting blades 86 and outwardly curved deflectors 87.

Title: Impact compacting machines
IPC: B28B1/04
Filed: 1971-06-01
Abstract: 1335721 Impacting machine INCA GES FUR VERFAHRENSTECHNIK MINERALISCHER STOFFE mbH 1 June 1971 [18 June 1970] 18360/71 Heading B5A Briquettes are made from granular materials by an impact compacting machine, in which the maximum drop of the impacting weight is 0À8 metres and the minimum impacting energy is 0À3 metrekilopond per square cm. Briquettes are made from sand/water/binder using limes and stone, magnesite or sintered or powdered ceramic materials, to form fire resistant cladding fireclay blocks or magnesite blocks. As described, granular material 8 is placed in a mould box 7 closed by an impact plate 9 that is movable by a stroke device 10. An impact weight 6 guided by rails 3 and suspended from a bridge 4 is operated by a stroke-and-latch device 5 to compact the material 8. The first blows of the weight 6 have less energy, that is increased stepwise or continuously. Eight strokes give a briquette with a bulk density of 1À9 gm/cm<SP>3</SP> and an acceptable, limited amount of comminution of added bulking clay. The ratio of mass of the plate 9 to the single blow energy is kept in the range 1 : 1À5-1 : 4. Retractable spikes 11 produce locating apertures in the finished briquettes. A high mass impact plate 9 reduces its initial velocity on impacting, and reduces after-blow oscillation and plate vibration.

Title: Improvements in and relating to windscreen wiper mechanisms
Inventor: BLAZEY SIDNEY HENRY
IPC: B60S1/24
Filed: 1956-06-15
Abstract: 800,176. Windscreen wipers. GENERAL MOTORS, Ltd. June 5, 1957 [June 15, 1956], No. 18526/56. Class 138(1). A windscreen wiper mechanism comprises a drive member 12 which has attached to it a gear segment 11 with a pitch circle centre B. The drive member 12 is able to pivot about the shaft 9. A second segment 7 with pitch circle centre A. engages segment 11 and pivots about shaft 1. Movement of drive member 12 by means of the connecting rod 15 causes the rotation of segments 11 and 7 in such a manner that the respective distances between the pivot axes 9 and 1 and the point of contact between the two segments varies inversely and continuously throughout the arc of oscillation. Thus it is possible to enable the velocity of the wiper 19 to reach a maximum when at the centre of its stroke and to move slowly at the extremeties of its path, thereby reducing noise at the time of reversal. In place of gear segments made of metal or nylon, a frictional engagement between the segments may be employed.

Abstract: 1,149,860. Electronic musical instruments. WARWICK ELECTRONICS Inc. 28 April, 1966 [28 April, 1965], No. 18714/66. Heading G5J. In a monophonic instrument, operation of a key produces both the associated tone signal and a gating signal which allows the tone to pass to the output with a percussive waveform. As shown, operation of any of keys 11 allows the output of its associated tone generator C 2  which is in the form of a succession of rectangular waves 21 to pass through a frequency halving circuit 18 to a diode 38. This diode normally prevents the signal reaching voicing networks at the output 59, but operation of the key also removes the earth made by the normally closed top contacts of the keys and a diode 28 from a condenser 30 which begins to charge. A waveform as shown at 33 appears at its output which opens the diode 38 so that a waveform as shown at 51 passes to the voicing networks and the output, decaying as the condenser 30 becomes fully charged. A resistor may replace diode 28. In the arrangement of Fig. 2 (not shown), the note is sustained should the player release the key before the percussive pulse has completely decayed and a capacitor is provided to cut off the tone less abruptly than would be the case if the percussive signal were removed.

Abstract: 766,132. Animal traps. SADLER, G. B. June 22, 1955 [June 29, 1954], No. 18996/54. Class 5(1). An animal trap comprises a trapping member 9 pivotally mounted on a base plate 1 and having an extension 6 integral therewith. A lever 13 passes through an aperture 16 in the extension member and is capable at one end of being engaged in an aperture 17 formed in a bait holding member 10 which is pivotally mounted on the base plate. The other end of the lever 13 bears against a leaf spring 14 and is formed with a shoulder 19. In order to set the trap, the extension member 6 is depressed towards the base plate against the action of a spring 5, thereby raising the trapping member 9. On passing the member 6 over the shoulder 19 of the lever 13, the spring 14 acts so as to bring the lever into a position in which it can engage the bait holding member on tilting the latter in an anti-clockwise direction. Once the engagement has been effected, the trap remains in its " set " position when the pressure on the member 6 has been released. When an animal removes the bait from the prong 18 of the bait-holding member, the latter tilts so as to release the lever 13, whereupon the extension 6 is raised by the action of the spring 5 and the trapping member 9 falls on to the base plate 1.
