Abstract: 1389947 Measuring roughness BOWATERS UNITED KINGDOM PAPER CO Ltd 12 Sept 1973 [12 June 1972] 27262/72 Headings GIM and G1S [Also in Division G3] Apparatus for measuring the roughness or permeability of paper for example or a small gap between a surface and a fluid outlet, or the bore of narrow tubes, or the fluidic resistance of porous plugs, comprises a wheatstone bridge arrangement using known substantially linear fluidic resistances, see also Heading G3H, the term "linear resistance" meaning that resistance in which a mass gas flowrate is proportional to the difference in the squares of the pressures upstream and downstream, or a liquid flow where the mass flow-rate is proportional to the difference in the pressures upstream and downstream. In Fig. 2 for example the gauging head 2 of Specification 1063657 clamps a paper sample 4 against a support 3, the air escaping from the head along the surface of the paper constituting a measure of the paper roughness which may be related to the reading on a transducer T across a known resistance 1, or. a pressure gauge 5. The plug I can be a sintered glass plug or a packed bed of spherical glass, ceramic, metal or plastics particles of 0.05-0.80 mm diameter in the case of glass. The particles are constrained against relative movement by pressure, or bonding with hot melt compositions including thermosetting resins, shellac, bitumen and cellulose esters, or the bonding may be by sintering and the need for adhesive may also be practicable for beds of thermoplastic beads. The fixed resistance of Fig. 5 comprises a tube 6 of about 3 mm inside diameter containing perforate plates or meshes 7, 8, 9 spaced by packed particles 10. Mesh 8 is urged by a spring 12 and sleeve 11 against the non-bonded particles to hold them fixed. In Fig. 6 shellaced glass spheres and held by meshes 14, 15 and spring 16, the housing being heated to 100‹C to fuse the shellac. After cooling, the mesh 15, plate 17 and spring 16 are removed so that the bed may be scraped away to give a required rate of flow. Formulae concerned with the mathematical design of linear resistances are explained.

Abstract: 828,825. Printing machines. DRUCKMASCHINENWERK PLANETA VEB Sept. 10, 1956, No. 27591/56. Class 100(2) Inking apparatus; damping apparatus. In a hydraulic device for axially vibrating a roller in inking or damping apparatus, wherein the control valve is switched by a striker 21 moving with the vibrated parts, abutments 23 engaged by the striker are carried by left-hand and righthand threads on the control valve spindle 22, which can be turned by an external knob 22a to vary the abutment spacing and hence the roller travel. In a press having five reciprocating distributing rollers (Fig. 1, not shown), two of these are coupled by a two-armed lever giving simultaneous opposite-phase movement, and one roller of this pair and the remaining three rollers have hydraulic motors 9, 10 attached to their respective shafts 20 and operated by oil supplied by a 4- way gear pump via adjustable relief valves individual to each motor; the oil return from each motor is taken via one of four adjustable butterfly valves whereby the number of reciprocations per minute is controlled. The motor shown is fed with oil through a bore 12 connected by a channel 13 or 17 in a main control valve 14 to conduit 15 or 16, each leading to one end of the fixed cylinder 9; the channel 13 or 17 not so engaged serves to connect the other end of the cylinder to a return bore 18. The valve 14 is switched by coupling the spaces at its ends alternately with the supply and return bores 12, 18 by a pair of valves 24, 25 carried by the spindle 22. The striker 21 may have a square bore, or a cylindrical bore with a key, engaged by a rotatable but axially restrained twisted square-section spindle, or a round spindle with a helical groove, which is thereby rotated as the piston 10 reciprocates, to cause a pointer attached to the spindle to indicate the exent of movement on a dial; a hydraulic or electrical transmission between the member 21 and the pointer may be substituted. In a modification the cylinder 9 is formed within the roller shaft 20 and moves over a fixed piston mounted on the end of a piston rod of cross-sectional area half that of the cylinder and having two bores leading to the opposite sides of the piston; the side nearer to the rod is permanently connected to the oil supply, and the other side is alternately connected to the oil supply or to a return pipe by a single-channel valve corresponding to the valve 14.

Title: Magnetic memories
IPC: H01F10/06
Filed: 1975-07-01
Abstract: 1519843 Magnetic storage arrangements SPERRY RAND CORP 1 July 1975 [1 July 1974] 27655/75 Heading H3B Information represented by magnetic bubble domains 32 with NÙel boundaries, Fig. 4, is stored in a ferromagnetic thin film layer 30 having an easy axis of magnetization 31 in its plane, the film being of such minimal thickness as to be incapable of supporting Bloch or cross-tie domain walls. The layer is generally magnetized in the '0' direction M F , but a bubble directed in the antiparallel '1' direction 34 may be formed, or erased, at the intersection of a word line 38 and a digit line 40, by the coincident application of an alternating word line current field H AC  from a word driver 66, and a selected positive or negative digit line current field +H B , - H B  from a digit driver 70. Reading is effected non-destructively by the alternating field H AC  alone, and produces an output of doubled frequency in a digit line sense amplifier 72 if a bubble is present. The formation of a bubble is stabilized by a D.C. digit bias field H B  supplied by bias drivers 60, 61, 62, and is directed in the positive '1' direction under a digit line and in the negative '0' direction on either side of that line, auxiliary digit lines 39, 41 being provided for the purpose. Alternatively the auxiliary lines may be omitted by plating each digit line 104, 106, Fig. 11, with a continuous layer 105, 107 of a remanent magnetic material such as cobalt. These layers provide in association with a magnetic keeper plate 116 the alternate positive and negative bias fields + H B , - H B . The magnetic film may consist of 81% Ni-19% Fe limited in thickness to 50Š to 250Š, and may be adjacent a ground plate 114. Further bubble stabilization is obtained in both arrangements by a D.C. word bias field +H wp  applied during a switching operation from a word pulse driver 64, and also by inclining the orthogonal word and digit lines relative to the easy and hard axes of the film so that an angle of between 5 degrees and 20 degrees is subtended.
