Title: Overload release mechanisms
IPC: A01D34/07
Filed: 1963-10-02
Abstract: 986,363. Mowing machines. FORD MOTOR CO. Ltd. Oct. 2, 1963 [Oct. 22, 1962], No. 38718/63. Heading A1F. [Also in Division F2] An overload-release mechanism for a mower-support which is adapted to break back under excess load, comprises a link 25 having two members 34, 37 which are connected together and are slidable together against the action of a spring 30, the spring being stressed by extension of the link until a predetermined extension has occurred, whereafter the spring becomes disengaged from one of the members to permit further extension of the link to occur freely. The mower comprises a transverse arm 12 carrying the cutter-bar and supported by the draught-links 15 of a tractor, the link 25 being connected between the arm 12 and the pivot 29 of the draught-link 15. The member 25 is tubular and has the tube 34 freely slidable within it, limited by the spring 30 which is housed between a collar 31 and a flange 35 on the tube 34. The rod 37 is freely slidable within the tube 34 but has a head 41 which is pressed against the flange 35 by a pivoted latch 42 loaded by a spring 45, so that relative movement of the rod within the tube will not normally occur. If the spring 30 is sufficiently compressed by overload, the flange 35 and head 41 will move down the tube 25 far enough for the head to disengage from the latch 42; the rod 37 will then be free to move relatively to the tube 34 until the head strikes an inward projection 49 in the lower part of the tube 34.

Title: Milling machine
IPC: B23Q39/04
Filed: 1957-12-13
Abstract: 837,456. Milling. DELISO, J. J. Dec. 13, 1957, No. 38830/57. Class 83 (3). A milling-machine comprises means to rotate a turret at fast-traverse and slow-feed speeds to carry a number of workpieces past a series of fixed cutters, and including a pair of discs adjustable to alter the points at which the rotational speed of the turret is changed. The turret is slotted to receive work-holding or indexing devices. A continuous chain driven by a motor 22 rotates a number of cutter-shafts 24, each mounted on an adjustable slide 30. The turret-shaft 16 is rotated through chain gearing driven by either a fast-, or a low-, speed motor, according to the energization of two electromagnetic clutches. The clutches are selectively energized by a switch 70 having an arm riding on the periphery of the pair of discs. The discs are similar, and have alternate lands 66, 68, and gaps 72, so that, by adjusting the discs relatively to the shaft 16, the distance between the ends of adjacent lands can be increased, so lengthening the time of the fast traverse. Swarf falls downwardly on to the base 10.

Abstract: 1,018,093. Surgical dressings. MOLNLYCKE A. B. Oct. 22, 1962 [Oct. 24, 1961], No. 39958/62. Heading A5R. A surgical compress is made by disposing an absorbent pad, e.g. disintegrated cellulose or cellulose sheets, between a thermoplastic film, e.g. polyethylene, and a liquid-permeable layer, e.g. gauze, the film being covered with a fibrous web, e.g. wet-strength paper, folding the edges of the film and web over the edges of the permeable layer to enclose the pad and treating with heat so that the film joins the fibrous web to the permeable layer. The permeable layer may be covered with a thermoplastic film layer which becomes perforated by the fibres present during the heat treatment. To assemble the compress, absorbent pads 3a, 3b, 3c are fed at regular intervals from a table 7 on to continuous superimposed webs of wet strength paper and plastic film which are drawn from rolls 11, 9. The pads are covered by a continuous gauze web drawn from a roll 15. The superimposed components are passed through a folding device 18, which turns the edges of the paper and film webs over the gauze, and then through heated pressure rolls 16, 17 which secure the folded edges to the gauze and form depressions 20 between the pads.

Title: Production of lubricating oils
IPC: C10G47/00
Filed: 1964-10-02
Abstract: Lubricating oil is obtained from a low-viscosity index heavy oil boiling in the lubricating oil range and containing aromatics and poly-cycloparaffins by hydrocracking the latter constituents and aromatics to lower boiling dealkylated aromatics, cycloparaffins and paraffins under conditions near the reforming threshold (the point at which aromatization and hydrogenation processes are in balance) including a temperature of 700-900 DEG  F. and a pressure of 1000-4000 p.s.i.a. to obtain a product without significantly decreasing the total aromatic content and recovering a high viscosity index lubricating oil boiling above the initial boiling point of the feed and which may be dewaxed.  Suitable conditions are such as to effect at least 10% dehydrogenation of perhydrophenanthrene to aromatics (as indicated in a graph) and a space velocity of 0.3-5 vol/vol/hr. using as catalyst a sulphided Group VI preferably wiht a Group VIII metal on a cracking support. The product may be catalytically hydrogenated to obtain a stable product, and fractionated to recover fractions boiling over a range not exceeding 100 DEG  F.

Title: Improvements in or relating to storage devices for electric pulses representing information
IPC: G06F3/08
Filed: 1959-11-27
Abstract: 910,382. Electrical digital-data-storage-apparatus. COMPAGNIE DES MACHINES BULL. Nov. 27, 1959 [Dec. 4, 1958], No. 40425/59. Class 106 (1). A device for the cyclic repetition of electric pulses comprises a plurality of capacitors each having one electrode at a fixed potential and the other connected to a separate contact stud of a rotary switch on which slide at least two brushes, the arrangement being such that a capacitor is charged by the first brush and discharged one cycle later by the second brush, the discharge being available for a utilization circuit and also to control the charging of a second capacitor for a further cycle if necessary. As described, the sensing of a hole in a record card 20 completes a circuit from a + 48 V. source, via cam contacts C27, C28, a common brush 29, conductive roller 25, brush 22 and switch arm 80, to the winding 77 of a relay which closes contacts 77b to apply a + 2 V. potential, via a brush 73, to one electrode of a capacitor 53 whose other electrode is connected to earth. A drum 30 carrying capacitors 53 to 69 rotates counterclockwise at a rate such that the capacitor (53), receiving the pulse for storage, reaches a second brush 75 one card cycle later. On reacing the brush 75, the positively charged capacitor fires a thyratron 98, energizing a relay 90 which closes contacts 90a and connects the + 48 V. supply via line 89 and switch 85 (in the lower position) to a utilization circuit. Also, with switch 80 in the lower position, the relay 77 may be energized again to re-store the pulse in the capacitor now contacting brush 73 for a further cycle. A third brush 74, connected to a negative potential of - 10 V., ensures that no positive charge is inadvertently left on a storage capacitor after passing brush 75. In a modification (Fig. 5, not shown) the drum carries two series of capacitors co-operating with two sets of brushes diametrically opposed. In another modification, by using relatively highvalue electrolytic capacitors the output relays can be operated directly, eliminating an electronic amplifier. In this case, undesirable sparking at the brushes is avoided by including inductive loads in the brush circuits (Fig. 8, not shown). The storage capacitors may be formed on the surface of a drum or disc by known coating techniques, or cylindrical-type capacitors may be packed in containers within the drum (Figs. 13 and 14, not shown).
