Abstract: 680,934. Piezo-electric crystals. GENERAL ELECTRIC CO., Ltd., and ROLLIN, L. May 9, 1951 [May 9, 1950], No. 11566/50. Class 40 (viii). The natural frequency of a piezoelectric unit is adjusted to a required value by sealing the unit in an envelope which also contains a filament coated with a material which, on passing a current through the filament, is sublimed on to the unit at a controllable rate. The general method of adjusting the frequency of a unit, constructed to have a frequency slightly higher than that desired, by subliming small quantities of non-conducting material thereon is described in Specification 589,108. As shown, the unit 1 is mounted on wires 3, which are connected through struts to a line 12. A tungsten filament 15 coated with sodium aluminium fluoride is connected to a heating supply 13. Leads 12 are connected to a circuit for measuring frequency, and the filament is heated until the indicated frequency is reached. The filament heating is provided with a switch to enable it to be controlled manually or automatically from the frequency measuring circuit.

Abstract: 703,617. Combine-harvesters; huskers. MINNEAPOLIS-MOLINE CO. May 10, 1950, No. 11659/50. Class 58. [Also in Group XXXI] Relates to a tractor-implement combination in which the implement shown in Figs. 6 and 7 as a combine harvester and in Fig. 9 as a husker is mounted on the tractor (see Group XXXI) by means 85 on the front axle housing 14 of the tractor and means 100, 101 on the side of the tractor frame. As shown in Figs. 6 and 7 the combine harvester is of the " straight-through " type and has a comparatively narrow housing 105 containing the usual threshing elements including a forward beater 106 to the rear end of which housing is a hood 107 from which straw is discharged. Over the housing 105 is a grain tank. 108 to which the clean grain is delivered by a conveyer 109, a tailings conveyer returning any uncleaned grain for recirculation. A header 111 having the usual sickle and conveyer mechanism is supported at the front end of the housing 105 to permit up and down adjustments of its front end to regulate. the cutting. These adjustments are effected through linkage 149, 147, a hydraulic ram 139 and a supply pump, the pump, ram and link 147 being carried by the tractor. The combine harvester is driven from the tractor engine through a belt drive, a pulley 126 serving to tension the belt and to declutch such drive and the movement of the pulley being controlled from the tractor. As shown in Fig. 9, the husker unit comprises a bed frame carrying the usual husking bed and conveyer assemblies and supporting a rearwardly directed elevator 153 for delivering the cleaned corn. Forward of the bed frame and pivoted thereto for up and down adjustments in the same manner as the header 111 in Fig. 6 are snouts 154, between which operate the usual gathering chains or snapping rolls. Surmounting it is a conveyer 155 for delivering the harvested ears to the husking mechanism. The husker unit is driven in the same manner as the combine harvester shown in Figs. 6 and 7.

Abstract: 1447424 Laying fabric G STUMPF 18 March 1974 [30 March 1973] 11988/74 Heading D1S A fabric laying machine for reciprocation along a laying table 1 comprises a carriage 12 carried by a frame 5 for mounting a supply 13 of fabric 19, power rollers 16, 17 carried by the frame 5, transfer means 18 operable to move the roller 17 from a first position in which it forms a nip with the roller 18, Fig. 1, to a second position in which it is spaced apart from the roller 16, Figs. 2 and 3, means to rotate the rollers 16, 17 when the roller 17 is in its first position to pull fabric 19 from the supply 13 through the nip of the rollers 16, 17, and a deflecting roller 20 carried by the frame 5 to cause the fabric 19 to contact the roller 16 over an arc of contact when the roller 17 is in its. second position. As shown, the frame 5 runs on wheels 4 on rails 3 on the table 1. A follower carriage 5a is releasably coupled to the frame 5 and is provided with wheels 5c running on the rails 3 and a platform 5b for an operator. At least one support wheel (not shown) for the carriage 5a runs on a rail 5d. Two guide rails 7 guide either a web-severing device 9, Figs. 1 and 2, releasably arranged on an endless chain 8 or a laying head 10, Fig. 3. The carriage 12 is displacable on wheels 11 transversely to the direction of movement of the frame 5. An edge-sensing device 21 acts to shift the carriage 12 in response to any deviation of the longitudinal edge of the fabric from the required path. The transfer means for moving the roller 17 relative to the roller 16 includes bars 18. For laying a double layer fabric, e.g. a longitudinally folded fabric, the carriage 12 is provided with horizontal support arms 23, Fig. 1, adjustable, according to the decrease in the diameter of the fabric supply roll 13, to achieve vertical drop into the nip between the rollers 16, 17 with the roller 17 in the first position. This adjustment is controlled by a sensing device (not shown), preferably, combined with the device 21. To lay a single layer fabric; the carriage 12 of Fig. 1 is replaced by that of Figs. 2 and 3, the roller 17 is moved to its second position and the fabric 19 is lead under the roller 20 and around the roller 16 which acts as a delivery roller. The sensing device 21 is moved from a position 21a to a position 21b. The carriage 12 of Figs. 2 and 3 is provided with vertical roll supports 24 and cantilever arms 25 carrying rollers 26. If it is desired to sever the fabric at the end of each lay, a severing device 9, Figs. 1 and 2, having a power driven circular knife 27 engagable in a cutting slot in a cylinder 28, is provided. To form a zig-zag pile of fabric, the device 9 is replaced by a head 10 having laying blades and run-up cams 29. The chain 8 supporting either the device 9 or the head 10 adjusts the height of these members as the height of the fabric pile 22 increases.

As applied to the mill shown in Fig. 1, the mill 1 is fed through an inlet 2 and a fan 4 discharges ground material to air separators 5, 6, the coarse material deposited in the separator 5 being returned to the mill and the finely ground material deposited in the separator 6 is discharged through a pipe 11 as the final product, or deposited in separator 13. Ground material is extracted from the mill by mechanical means 15<1> and is discharged into the air or other sifter 13 from which the coarse material is returned to the mill and the fine material discharged at 16. In Fig. 2 hot air is sucked in through a pipe 2<1> by a fan 4 and the coarse material deposited in the cyclone 6 is discharged into a silo 19 from which it is conveyed by a screw 20 into the discharge outlet 21 of the fan 4 and conveyed to the place of use. Ground material from the mill is mechanically conveyed to the separator 13, the coarse material being returned to an intermediate stage of the mill whilst the fine material is conveyed to the silo. In a modification the separator 13 may be embodied in the pipe line 18<1> to the cyclone 6. The cyclone 6 and silo 19 may be dispensed with, the air current from the mill carrying the pulverized particles directly to the place of use.
