Title: Improvements in and relating to magnetic recording or reproducing heads
Inventor: JACOBS ERIC WILLIAM
IPC: G11B5/29
Filed: 1955-01-19
Abstract: 783,794. Magnetic recording and reproducing heads. ENGLISH ELECTRIC CO., Ltd. Jan. 13, 1956 [Jan. 19, 1955; Jan. 19, 1955], Nos. 1621/55 and 1622/55. Class 40 (2). A multiple magnetic head unit comprises a unitary elongated support member to which are attached a plurality of magnetic record heads disposed along its length. In one embodiment, individual heads 9 are first assembled in a jig 14, Fig. 2, provided with locating slots 14b. The gaps 10a of each head bestride a tightly drawn tape 17 of non-magnetic material, such as phosphor bronze or beryllium copper, in order to align the gaps 10a, and steel balls 16 effect an accurate spacing of the poletips of each head. The heads are temporarily held in position by the spring teeth 18a of a comb-like member 18, Fig. 3. At this stage a low melting point alloy 21a, such as a eutectic composition of bismuth, cadmium and lead, which melts at 91 ‹ C., is cast into the individual recesses between the steel balls. A small amount of plastic material is then placed at the base of each recording head adjacent to the balls 16 and tape 17 to secure the heads in position. A slotted metal tube which is to become the container for the heads is placed over the heads as shown in Fig. 4, and thermosetting resin 21b is introduced through terminal apertures 19b prior to the fitting of terminal blocks 20. When the resin is set, the complete unit is removed from the mould and the fillter material 21a removed by heating above the melting point. The metal ribbon or tape 17 remains adhering to the resin 21b and is cut away to leave only those parts filling the slots 10a. In another embodiment, Fig. 7, a mounting tube 27 has a segmental support plate 28 brazed or cemented to it, after which transverse parallel slots 27a are cut in it. Each magnetic has cemented to it an aluminium bar 31, the ends 31a of which rest upon the bottom of the slots 27a. A cement may be used to secure the ends 31a of the bars 31 to the tube 27, but before this cement has set the heads may be manipulated so that the noses lie in required position, as determined by the travelling microscope 30. Each recording head may be locked in position by wedging it so that it is firmly held against a ground side of the slot accommodating it, after which moulding material may be introduced into the tube 27. In a modification of this embodiment, Figs. 8 and 9, individual heads are secured to clamping blocks 42 which are then screwed to a flat surface 40b machined on the thickest part of the wall of an eccentrically bored support tube 40.

Title: Farm implements for raking, tedding, windrow turning or similar operations
IPC: A01D78/00
Filed: 1966-01-13
Abstract: 1,126,769. Haymaking machines. R. M. WORREL and H. A. HUEBNER. 13 Jan., 1966, No. 1738/66. Heading A1F. The rake-wheels of a haymaking machine are rimless and each comprise spokes 60 radiating from a hub, the outer ends of the spokes carrying peripheral tined segments 85, 86 pivotally mounted for movement between positions substantially concentric to the hubs and positions outwardly pivoted therefrom. The machine is similar to that described in Specification 1,126,770 and comprises three rake-wheels 30 mounted on a common shaft 31 that is carried by a tractor so that it extends horizontally but oblique to the direction of travel of the tractor, the central rakewheel being concentric with the shaft and the outer ones being carried by outriggers 39, 54 pivoted on the shaft and suspended by springs 92 from a cross-bar 24 forming part of the frame carrying the shaft 31. Each spoke terminates outwardly in a forked bearing 61 within which are pivotally mounted two mounting blocks 70, 71 for the segments, each segment consisting of a pile of wires 87 of different lengths, the inner end of the pile being bonded to a mounting block and the outer end of each wire formed with a loop 89 terminating in a tine 90. Clips 91 hold the wires together in the manner of a leaf-spring. Each segment is prevented from inward movement further than a circumferential position by a step 64 on the forked bearing 61, and abutments 77, 78 on the respective mounting blocks restrain the segments from excessive outward movement. As each wheel rotates, the segments fall, under gravity, into circumferentially extending positions in the upper part of their travel, but fall outwardly into groundengagement in the lower part, thereby increasing the raking width of the machine. As shown in Fig. 2, six spokes are employed and each segment extends over 60 degrees, but in a modification (Fig. 18, not shown) only three spokes are used so that the wheel-circumference is discontinuous. In a further modification (Fig. 14, not shown) the tines are separate from the segments, which comprise rigid, pivoted, arcuate bars.
Patent GB-575315-A (GB)
Title: Process for effecting molecular rearrangements in fats and fatty oils
IPC: C11C3/10
Filed: 1943-02-02
Abstract: The rearrangement of fatty acid radicles in a triglyceride mixture is effected by heating the mixture in the presence of not more than 10 per cent water and under a pressure at least as great as the vapour pressure of the mixture containing the water.  Thus, a mixture of tristearin and free oleic acid is converted by such treatment to distearo-mono-olein, dioleomonostearin and free stearic acid.  If any hydrolysis has taken place during the treatment, the pressure may be released, the water boiled off, and heating of the mixture continued to re-esterify free hydroxyl radicles.  After the treatment, any free fatty acid may be removed by alkali-refining or by distillation or by esterification with glycerol.  Triglyceride mixtures mentioned are coconut oil and tristearin, hydrogenated cottonseed oil and oleic acid, coconut oil and hydrogenated cottonseed oil and even a single fat such as coconut oil or palm oil.

Filed: 1955-01-20
Abstract: 789,061. Agricultural implements. OKSANEN, A. Jan. 20, 1955, No. 1763/55. Class 6(1).  A device for connecting a disc harrow to a tractor provided with hydraulic lift links comprises a drawbar 9 attachable to the lower lift links and pivotally mounted by means of a pin 13 between two plates 10 attached to the harrow. The pin 13 slides in slots 14 in the plates 10 and when the harrow is being drawn by the tractor the drawbar 9 may pivot between limits determined by two members 22 which abut against the drawbar. To prevent swinging of the harrow when it is raised clear of the ground by the tractor, the tractor is first backed to allow a projection 18 on the drawbar to engage between guide plates 20 thus holding the drawbar rigid with respect to the harrow. Specification 789,062 is referred to.

Abstract: Pulverulent material, suspended in a combustible gas or gas supporting combustion, is introduced into a vertical reaction chamber in a direction tangential to the wall thereof, and therein caused to form a gyrating flame, which is subjected to a positive upward suction in line with the axis of gyration.  Reference is made to oxidizing sulphur or carbon, to reducing sulphate of lime, to reduction of zinc ores with subsequent oxidation of the zinc vapour, and to conversion of ferric oxide to ferrosoferric oxide by heating in an oxidizing atmosphere at 1000--1400 DEG  C.  In an apparatus suitable for the treatment of zinc ores, the burner chamber A consists of two cones connected by a <PICT:0406124/III/1> cylindrical portion 3.  Powdered ore, together with producer or town gas, acetylene, &c., or pulverized coal from pipe 6 and air from pipe 7, is blown tangentially into the chamber through one or more pipes 4. Fan 9 draws additional air up through the chamber. Zinc vapour passes to chamber 11, and is there oxidized by air from pipe 10, the oxide vapour passing to chamber 12.  The combustion air is preheated by passage through chamber 13 surrounding chamber 11.  The vanes of fan 9 may be divided into two parts separated by a partition, air being drawn through one inlet and zinc vapour through the other, so that oxidation is effected on the side of the fan remote from chamber A. Hot unvolatilized particles collect in chamber 14, and serve additionally to heat the air drawn in at the bottom of chamber A. The lower cone and cylindrical portion 3 may be perforated to permit entry of additional air.  In a modification of the apparatus, there are disposed below pipes 4 one or two annular pipes, each supplying a series of gas burners.  In a further modification, one tangentially-disposed gas burner may be provided, combustion air being supplied under pressure from an annular chamber surrounding the cylindrical portion.
