Title: Associative Store
IPC: G11C15/02
Filed: 1967-11-29
Abstract: 1,151,466. Associative stores. INTERNATIONAL BUSINESS MACHINES CORP. 29 Nov., 1967 [7 Dec., 1966 (2)], No. 54251/67. Heading G4C. [Also in Division H3] An associative store has two cells per bit, each cell having two magnetically-coupled anisotropic magnetic films. In the associative store of Fig. 4, each bit is stored in both true and complement form in respective storage cells, e.g. A1 (true) and A1<SP>1</SP> (complement). Each cell has two anisotropic magnetic films separated by a layer of insulator, viz. a high coercivity " storage " film and a low coercivity " read " film. The magnetic vector in the storage film lies in one sense or the other (depending on the bit stored) along the easy axis and biases the read film so that its magnetic vector, M in Fig. 4, lies antiparallel along the hard axis of the read film, the easy axes of the two films being orthogonal. Any cell storing 1 has the storage film only partially switched so that the read film is barely saturated in one sense to store 1 but is well into saturation in the other sense to store 0. During associative interrogation, bit drivers 26, 261 pulse bit lines 24, 24<SP>1</SP> positively and negatively respectively to interrogate for 1 or negatively and positively respectively to interrogate for 0. Any mismatch produces a pulse in one of detection lines 20, 20<SP>1</SP> depending on the sense of the mismatch, a match detector 22 ORing the detection lines 20, 20<SP>1</SP>. The array of cells is staggered as shown for noise reduction. A word may be non- destructively read out by pulsing both lines 20, 20<SP>1</SP> with the same polarity at low amplitude, a sense pulse being produced on one of the two bit lines 24, 24<SP>1</SP> in each case, the two bit lines being combined in a differential sense amplifier 28. To write in a word, the word is cleared by pulsing both lines 20, 20<SP>1</SP> (or other lines not shown) at high amplitude, then the new word is written by coincident-current technique pulsing lines 20, 20<SP>1</SP> and (with data-dependent polarities) bit lines 24, 24<SP>1</SP>. Fig. 7 shows one cell of the associative store of Fig. 10. A high coercivity " storage " magnetic film 10 and a low coercivity " read " film 12 with easy axes EA1, EA2 interact as before but are separated by a bit line 14, the ends of which are connected to a bit driver 18 directly and via a conducting ground plane 16 respectively. 20 is a match detection line, 24 is a word write line, 28 is a magnetic keeper and 18 is insulator. In the store of Fig. 10, each bit is stored twice, e.g. in cells A1 and A1<SP>1</SP>. Each bit position, e.g. A1, A1<SP>1</SP>, to be associatively interrogated is pulsed positively on line 14 to interrogate for 1 or negatively on line 14<SP>1</SP> to interrogate for 0, a pulse being induced on line 20 in the ease of mismatch. A word can be read out on the lines 14 non-destructively in pulse/ no-pulse form by pulsing line 20. Coincident current write-in is possible using lines 24, 14, 14<SP>1</SP>.

Abstract: 1,159,260. Laminates. R. FREUND. 21 Dec., 1966 [29 Dec., 1965], No. 57109/66. Heading B5N. [Also in Division F2] A laminate used in making bearings comprises a sheet of flexible material 11 and a plurality of exposed substantially parallel filaments 12 of bearing material having a diameter at least 0À001 inch and adhered to said sheet in a single layer. The flexible backing is suitably of cellulose acetate and the filaments may be polytetrafluoroethylene, nylon or metal, e.g. aluminium or silver, or mixtures thereof. Oil wick threads may be mixed with the filaments for the spreading of lubricant. The material may be prepared by passing a group of filaments between grooved roller 48 and drum 38, which has been previously covered with the backing sheet coated with adhesive. The drum 38 is then slowly turned so that it turns slightly more. than one revolution whilst the grooved roller slides on rod 41 a distance equal to the width of the group of filaments, thus avoiding crossing of filaments, the tube formed being cut open to form a flat sheet. In an alternative apparatus the laminate is formed as a continuous strip, and if desired the adhesive may be applied immediately prior to bonding of the filaments. The filaments may be circular, semicircular or triangular, in section and may have retaining grooves. The filaments may be arranged in a herringbone pattern.

Abstract: 1331108 Barrel apparatus for electrolytic treatment UDYLITE CORP 29 Dec 1970 [9 Feb 1970] 61628/70 Heading C7B [Also in Division F4] Articles are treated in bulk (e.g. electro-plated or, in sequence, cleaned, rinsed, plated, coated and/or dried) within a substantially cylindrical perforated barrel supported with its axis horizontal and while given an oscillating rotary motion about its axis. The barrel has a longitudinally extending slot-like opening 2 of a width less than 1/6 the circumference of the barrel's treating zone and, opposite the slot, at least one tumbling rib 6 or wall surface disposed to extend inwardly of the otherwise regular cylindrical shape of the barrel's interior. The barrel's rotary motion is limited so that the articles do not fall out of the slot, the total rotary movement being 180 degrees to 220 degrees. Stop means may be provided for this purpose which may be adjustable to allow complete rotation of the barrel for unloading Fig. 15 (not shown). The barrel may have circumferential ribs or corrugations and may have partitions along its length dividing the barrel into separate compartments. As shown in Fig. 1, the barrel is rotated and periodically reversed by a periodically reversed motor 18 through gear and an overide clutch and gear mechanism 14. Alternative means for oscillating the barrel are described with reference to Figs. 7-11, (not shown). Cathodes 21 are supplied with current through connections 19 and lugs 15 of the barrel supporting frame 9, 11, 15. Anodes may be provided within the barrel and/or within a plating tank so as to at least partially surround the barrel. A barrel for an electrolytic process may be of synthetic or natural hard rubbers, polyvinyl chloride resins, poly methyl methacrylate resins, phenol formaldehyde resins or polypropylene, but for non- electrolytic processes may be of metal. Articles may be subjected to treating sprays or drying gases, e.g. hot air, injected through the open mouth of the barrel Fig. 14, (not shown). Barrels with their frames may be conveyed through loading, treating and unloading stations Fig. 12, (not shown), or loading and unloading may be at a single-station.
