Patent GB-1234346-A (GB)
IPC: G11C13/04
Filed: 1969-12-08
Abstract: 1,234,346. Read-only stores. INTERNATIONAL BUSINESS MACHINES CORP. 8 Dec., 1969 [15 Jan., 1969], No. 59765/69. Heading G4A. [Also in Division H3] An optical memory comprises a stack of transparent memory planes, in which each plane has a plurality of domains for storing binary information and in which a linearly polarized light beam transmitted through the stack during a quiescent state is unaffected by domains of each of the planes; and means for disturbing all the domains of a selected plane, whereby the optical properties of such domains are modified, causing a modulation of the polarized light beam. Using ferro-electric, antiferromagnetic or magneto-optical material in the planes and using domains oriented in opposite directions for 1 and 0 respectively, application of an electric or magnetic field or stress to the selected plane rotates its domain vectors so that 1 and 0 rotate the plane of polarization of light differently. The light emerging from the stack is received by an array of photodiodes. Readout is non-destructive.

Abstract: 1,238,501. Coating. E.I. DU PONT DE NEMOURS & CO. 21 March, 1968 [21 March, 1967], No. 13743/68. Heading B2E. [Also in Divisions B5, C3 and D2] Aromatic linear polyamides, polyimides, polyimidazoles, polythiadiazoles and polyoxadiazoles which are contaminated by halide ion are intimately associated with 0.1 to 15 wt. % of a degradation inhibiter which is a manganese, zinc or bismuth oxide; a manganese, zinc, bismuth or aluminium hydrated oxide, hydroxide or nitrate; a manganese or zinc carbonate or bismuth subcarbonate; or a manganese, zinc, bismuth or aluminium organic acid salt which is pyrolysable to an oxide below 300‹C to reduce thermal degradation when heated in contact with copper or iron. The intimate association may be effected by incorporating the inhibitor in the polymer or by coating it on the polymer or on another part of an article which contacts the polymer. The combination of certain of the inhibitors with polyamides which is the subject of Specification No. 1,238,502 is disclaimed. The polymer may be used to make a paper, in which case the inhibitor may be added to the starch or as varnish for metal bodies which may first be coated with the inhibitor.

Apparatus for the automatic production of gramophone records as described in the parent Specification is modified in that the first transfer means incorporates a pair of semi-circular claws E, actuated by mechanisms 21, 22, which encircle a space closed at the ends by two record labels, into which space mouldable material is injected to form a cake of material sandwiched between the labels, the cake then being conveyed by the claws to the next station for moulding into a record. The record moulding operation, its subsequent trimming and stacking, and the mechanism for transferring the product to the various stations from the moulding station is as described in the parent Specification. Record labels are supplied from laterally located magazines L1, L2 by vacuum grabs J1, J2 carried on a laterally reciprocating support S and vertically reciprocated by mechanisms 40, 41. A lower label is first fed to a table T, the claws are then closed and an upper label fed on to the claws. Moulding material is then supplied from a dispenser H and pipe Q to the space, a hole being formed in the material by a reciprocated pin Z.

The unit is supported by groundengaging means, e.g. rollers 74 disposed rearwardly of the blade 46 and by the connection to the frame which connection comprises a pair of laterally-spaced rigid members, preferably length adjustable tie-rods, 98 pivotally connected to both the unit and frame preferably by means of ball and socket joints 100, 103, and a third similar rigid member 96 vertically spaced from the pair of members 98 and pivotally connected to the unit preferably by ball- and socket joint 104 and to the frame preferably by a bushed bearing on roller 18 spindle; the connection allowing the cutting unit to move relatively to the frame 2 bodily upwards and downwards as well as to tilt relatively to the frame about any axis parallel to the direction of travel of the lawn-mower. Alternative embodiments involve the arrangement of the tie-rods 96, 98. Fig. 1 shows the lower pair 98 extending forwardly and upper 96 rearwardly of the cutter unit. In another embodiment both upper and lower tie-rods extend forwardly, in another, both rearwardly, and in a further embodiment the pair of tie-rods 98 are placed above the lower one 96 and all extend forwardly. The spacing between the cutting cylinder 40 and blade 46 may be adjustable by means of spring-loaded screws 62 acting between lever plates 60 and parts 64, 72 attached to side plates 42, 44 of the cutting unit. The height of cut is adjusted by means of nut 94 screwed to a spring loaded rod acting on an L-shaped lever 78 carrying roller 74.

Abstract: 1307137 Feeding web to a packaging machine SCANDIA PACKAGING MACHINERY CO 7 Sept 1971 41650/71 Headings B8C and B8R In a method of handling a continuous web of very thin film of wrapping material such as polypropylene, polyethylene, &c., longitudinal stiffening pleats are formed in the web without causing transverse stress therein and while the web moves along a path for subsequent feeding to an operational working station in, for instance, an article wrapping machine. As shown, three shafts 10-12 are geared together and are supported in side frames 15, 16, the top shaft 10 carrying a roller 17 over which a continuous transparent web S of thin material is fed into a pleating device and the shafts 11, 12 carrying rollers 25 and 28-30, respectively. A vertical frame, pivoted at 33 and operated by a handle 35, 36 through a toggle 34, 37, supports shafts 26a and 30 which carry rollers 26 and 31, 31A, 31B, respectively, which co-operate with the corresponding rollers 25 and 28-30. The pivotally movable frame 27 also supports four vertical grooved bars 40-43 which coact respectively with vertical strips 45 mounted on a stationary plate 45a on the frames 15, 16. The two centre bars 45 extend above the side bars 45 so that, as the web S is fed over the roll 17 and downwardly between the rolls 25, 26, the inner pairs of rods 45 and bars 41, 42 first form the inner two pleats, in the web S the two outer pleats, being subsequently formed by the outer grooved bars 40, 43 and the corresponding rods 45 as the web passes between the rollers 28-30 and 31, 31A, 31B. In this manner the reduction in width of the web is always made in an unpleated portion of the web so that the latter is stiffened without being transversely stressed and the pleats are not permanently formed. A chain of gears 52-54, connected to a source of power, not shown, drives the shafts 10-12 and also the shaft 50 of a revolving knife 48 which co-operates with a stationary blade 49 to cut the web S after it has been fed through a slot 46 to a wrapping station. The pleats are removed when the film is wrapped around an article.

In an endo-prosthesis. Figure 1, the distal member 1 for insertion in the lower leg is provided at its upper end with a flat or slightly concave surface 2, and the proximal member 3 for attachment to the upper leg is provided at its lower end with a convex surface 4. The two members are coupled by means of crossed links 5, 6 which are pivotally connected to each of the two members. In an exo-prosthesis, Figure 2, the tubular proximal member 10 for attachment to the upper part of the leg is connected at its lower end by a clip 11 to a bearing member 12 having a quadrant-shaped cross-section, the curved portion of the member 12 being provided with teeth 13.

The two members are connected together by means of two parallel links 18, one on each side. For the desired rolling movement, the embodiment of the Figure 2 can either have the axis of one of the link pivots adjustable, as by location in a slot form, or have the curved surface of the member 12 of varying curvature. The links of either embodiment may alternatively be accommodated centrally within the two members.
