Title: Apparatus for wiring memory matrix cores
IPC: G11C5/02
Filed: 1973-12-07
Abstract: 1445890 Assembling magnetic storage matrices VYCHISLITEL TSENTR SIBIRSK OTDELENIA AKAD NAUK SSSR 7 Dec 1973 [7 Dec 1972] 56877/73 Heading H3B In a wiring arrangement for a magnetic storage matrix in which apertured storage cores 3, Fig. 1, prethreaded in stacks 2 on parallel column wires 1 are threaded row-by-row at an aligning position 5 by rotationally advancing a coiled row wire 9 through the core apertures, the resulting looped row wire of a newly threaded row is straightened by rotating the wire from at least one end in such a direction as to eliminate the coil loops, while at the same time the terminations of the wire are moved further apart by a distance corresponding to the number of straightened turns. The straightened wire 15 with its cores is then moved into its final position in a frame 4, foil threading is effected by a coiling member 6 comprising a tapered spindle 7 in a housing 8. Row wire straightening is effected by a terminal member 13 mounted on a threaded rod 11 for rotation by a drive motor 12, the rod being moved longitudinally by engagement with a fixed nut 14 so as to take up the slack of uncoiled wire as rotation proceeds. In a modification, Fig. 2, both ends of a row wire are attached for straightening to respective terminal members 13 which rotate in opposite directions, each terminal member being coupled through gears 19, 20 to threaded rods 16 providing longitudinal movement in nuts 14. A similar arrangement, Fig. 3, has the added facility of each coil of the coiled row wire being straightened in turn. This operation is provided by soft pads 24 longitudinally driven by hollow feed screws 21 which are rotated by threaded rods 11, a plate 25 being removed so that the soft pads, on supporting nuts 23, rotate into engagement with the coiled row wire. As uncoiling proceeds the soft pads advance inwardly from turn to turn.

There are two diametrically opposite gaps in the loop, one of which provides feed terminals 15, 17, and at the other of which a resistive element 27 is serially connected, at points 23, 25. By making the transverse dimension d of the loop less than #/2 (#= wavelength at the lowest VHF operating frequency) it is stated that the directivity outwardly from the feed terminal gap is made greater than that in the opposite direction (Fig. 2, not shown). As described, the loop 10 includes two semicircular bands 11, 13, which are tapered down at their ends. The feed terminals 15, 17 are connected to input terminals 19, 21 of a low pass filter, which is comprised in a combiner 20 (Fig. 5, not shown). The dipole 30 is of "bow-tie" type and it has two triangular arms 31, 33, which may have bent-down extensions 75, 76 at their outer ends 37, 39. The feed terminals 35, 36 are connected to input terminals 41, 43 of a high pass filter which is comprised in the combiner 20. Parasitic elements for the dipole 30, which are also inside the loop 10, comprise a reflector strip 45 and three directors 47, 49, 51 each formed by a respective pair of strips 47a, 47b; 49a, 49b; 51a, 51b. Additional directivity for the UHF aerial may be obtained by providing L-shaped slots 53, 55 in the band 11, and L-shaped slots 57, 59 in the band 13, as shown. Said slots are stated to reduce side-lobes (Figs. 3, 4, not shown). The system may be embedded in suitable dielectric material, such as foamed plastic, and then be mounted on a mast 81.

Patent GB-710891-A (GB)
Abstract: 710,891. Calculating-apparatus. KIENZLE APPARATE GES., and MAIER, L. Oct. 31, 1951, No. 25522/51. Class 106 (1) Speedier operation of a ten-key machine is made possible by returning and clearing the pin carriage at an early stage in the machine cycle which follows each setting, so that a further item can be set whilst the previous is being registered. The carriage 10 is mounted for lateral movement between guide rails 21, 22 and the pins 9 are projected by spring-retracted thrust rods 7 operated through levers 5 from the keys 1. The carriage is driven by a spring 16 acting through a lever 53 and link 64, and step-wise movement is secured by a series of pins 14 which are successively disengaged from an abutment 15 by means of a push-rod 20 operated by a yoke 18 underlying projections 17 on the key stems. The guide rails 21, 22 are carried by arms of levers 28 and 35 (Fig. 4) pivoted at 38, 39 and interconnected at 36. At the commencement of the machine cycle, a pawl 27 on an actuating arm 26 displaces the carriage rearwardly, by engagement with the lever 28, to position the set pins in the paths of differential levers 30 connected to totalizer setting racks 66, 67. A bail 29 then releases the levers to their springs 31 and the set pins arrest the levers differentially, pawls 44 then holding the levers set by engagement with ratchet teeth 45 thereon. Immediately thereafter, and before the end of the half cycle, a projection 34 on the actuating arm 26 restores the carriage to its forward position by engagement with the lever 35, and then rocks a lever 51 which through a link 52 returns the carriage to the setting position against the spring 16. A further item can then be entered whilst the levers 30 are released to enter the item just set and complete the operating cycle.

Title: An electrical sealed contact relay of adjustable sensitivity
IPC: H01H51/28
Filed: 1978-06-14
Abstract: An electrical relay formed by a plurality of electrodes sealed in a tube of insulating material, of which at least one ferromagnetic electrode is flexible. To obtain a stable position to be selected from two positions, the so-called "rest" and "working" positions, of the common flexible reed the forces acting on the flexible reed are unbalanced by an additional magnetic flux providing dissymmetry of attractive force at the "rest" and "working" electrodes 2, 3. This dissymmetry is created by means of a magnet 10 which is attached to a pole piece 11 secured to the "rest" electrode 2 and is spaced from the "working" electrode 3 by a spacer 13 of non-magnetic, electrically insulating material. Final adjustment of the sensitivity of the relay is obtained by adjusting the thickness of the member 13 between the magnet 10 and electrode 3. <IMAGE>

Title: An arrangement for controlling a stream of solid particles
IPC: B65D90/54
Filed: 1978-06-28
Abstract: An arrangement for controlling a stream of fluidized solid particles flowing through a duct 14 to a discharge opening 15. The duct 14 prevents solid particles from reaching the discharge opening 15 simply by sliding in a non-fluidized state therethrough, due to the dimensions of the duct. Means are provided for controllably supplying a fluidizing gas to the duct to cause a fluidization of solid particles within the duct and this permits a controllable outflow of fluidized particles through the discharge opening. Said gas supplying means include a plurality of gas admission openings 19 in the wall of the duct and valve means 25 for individually controlling the supply of gas through each such opening. At least one additional separately controlled gas admission opening may be provided in the wall of a particle containing receptacle 12 at the input end of the duct at a level slightly above the outlet 13 of the receptacle. The apparatus shown may be used for gassifying coal. <IMAGE>

Title: Method of reinforcing earth structures
IPC: E02D3/12
Filed: 1979-03-28
Abstract: Facing units 3 for cladding the boundary surface of an earth structure 1 are bound to the structure by stabilising or reinforcing elements comprising perforated tubes inserted and held in the structure as will now be described. A hose is first inserted along the tube until the open ends coincide and water is pumped through while the tube is vibrated and subjected to longitudinal pressure. This leaches away surrounding soil to assist movement of the tube into the earth with clearance round it. Cement grout is next pump through the hose which is gradually withdrawn so that grout flows from the open end of the tube and through the perforations in bond with the soil. The other end of the tube is plugged and a facing unit passed over it and pressed against the soil through the medium of a thrust plate by a nut screwed on to the tube, this action also serving to tension the tube Alternatively a screwed sleeve may be attached to the end of a plain tube. The soil area behind the facing unit may also be grouted by a passage extending through the unit. An alternative tube is of cruciform section with fins or ridges to increase the area in contact with the earth. <IMAGE>
