Title: Devices for forming bales of crop
Inventor: LELY CORNELIS VAN DER
IPC: A01F15/08
Filed: 1987-07-10
Abstract: A device for forming bales of crop comprises a pick-up member (4) for picking-up crop lying on the ground, and a winding space (5) in which an expelling element (61) for expelling a bale is movably arranged. In this device simultaneously with the opening of the wall closing the outlet opening for the bale during operation, the expelling element can engage the whole length of the bale (in the direction of width of the machine) so that expelling forces are exerted on the bale uniformly distributed over the length of the bale. Thus the risk of parts of the bale getting loose during the removal thereof is avoided, which parts would have to be removed separately or picked up from the field. Also disclosed is a device for forming bales of crop comprising a pick-up member for picking up crop lying on the ground, a winding space, and a winding element (45A-Figure 5) which is pivotable with respect to a further part of the device in a manner such that it is at the same time suitable as an expelling element for removing a bale. <IMAGE>

Title: Corrosion protection tape
Inventor: TERAO NOBUATSU
IPC: C09J7/22
Filed: 1987-09-09
Abstract: A corrosion protection tape comprising an elongate sheet 1 made of an extensible material, e.g. plastics, with an adhesive layer 2 on its inner side and metal particles 3 adhered to the adhesive layer 2 in a longitudinal strip which is closely adjacent one (edge 4) of the two longitudinal edges of the adhesive layer 2 (which edges are also the edges of the sheet 1 in the illustrated embodiment). The tape can be wound on, for example, pipe such that the part of the sheet 1 having the strip of particles 3 directly contacts the outer surface of the pipe, the particles 3 thereby acting as a galvanic sacrificial anode eliminating or reducing the corrosion of pipe, and the other part of the sheet 1 is wound on the pipe so that it overlaps that part of the sheet 1 having the particles 3 and contacting the pipe. <IMAGE>

Patent GB-890295-A (GB)
Abstract: 890,295. Multiplying-machines. OLYMPIA WERKE A.G. July 24, 1958 [Aug. 22, 1957], No. 23862/58. Class 106 (1). In a machine for performing multiplication automatically by the shortened method, the members of a multiplier register are set, on the entry of the multiplier, to take account of the correction cycles by advancing a member an additional step when the member of next lower order is set to represent a digit greater than five. The multiplier register is formed by slides 16 carrying arms 24. When a multiplier key 36 is depressed, an aligner rod 46 is raised to free the slides 16 and a bar 33 is lowered so that in the ensuing cycle, which is initiated by the multiplier key, it will be moved to the right by a cam-controlled lever 5a. This movement restores the slides to their zero positions. At the same time a comb 15 is lowered and acts on studs 26 in the arms 24 to lower the latter and disengage their teeth 25 from studs 12 in pawls 9 carried by the differential levers 1 which, also at this time, are differentially set under the control of a pin carriage 7. The comb 15 is then restored upwardly so that the teeth 25 of the arms 24 engage the differentially set studs 12. On restoration of the differential levers 1, the slides 16 are thus set in accordance with the multiplier, the pawls 9 engaging abutments 31 on levers 29 when the differential levers reach their zero positions. However, if a slide 16 is moved beyond the " 5 " position, a cam slot therein rocks the lever 29 of the next higher order to remove the abutment 31 from the path of the pawl 9 for that order. The latter is thus able to move a further step and, in doing so, advances its slide 16 an additional step. The slides 16 are locked in set positions by the aligner rod 46 and continue to store the set multiplier as a constant factor until a different multiplier is entered.

Patent GB-909821-A (GB)
Abstract: 909,821. Moving coil instruments; ratiometers. SANGMMO WESTON Ltd. Nov. 25, 1958 [Nov. 7, 1957], No. 34756/57. Class 37. The meter of Specification 838,056 is modified for use as a ratiometer by providing two side-by-side coils and arranging that at least one of the two flux gaps G2, Fig. 4, is of non- uniform flux density which steadily increases (decreases) from one end of the gap to a maximum (minimum) at the centre of the gap and then decreases (increases) to the other end of the gap. The current directions in the two coils W1, W2 of the moving coil system produce respective torques t 1 , t 2  and t 3 , t 4 . Increase in the current through W1 rotates the assembly anti-clockwise, and those sides of coils W1, W2 lying in the non-uniform gap G2 will respectively move into regions of lower and greater flux until equilibrium is reached. The gap G2 is preferably bounded by cylindrical faces having radius r 1 , centre X1 and radius r 3  centre X2 respectively. The construction may be idential with that disclosed in Specification 838,056 except that two coils are used and that the yoke ring 31, Fig. 3, is subjected to a further machining operation to effect the required shaping with respect to the centres 39, 40. In other modifications the variable flux density may be a maximum at the centre position, Fig. 5 (not shown), or both gaps may have flux densities varying respectively in opposite senses, Fig. 6 (not shown). The outer gap surfaces need not be cylindrical.
