Title: Magnetic transducer head assembly
IPC: G11B5/48
Filed: 1955-03-15
Abstract: 797,594. Screw-and-nut gearing. INTERNATIONAL BUSINESS MACHINES CORPORATION. ; March 15, 1955 [March 18, 1954], No. 7513/55. Class 80 (3). [Also in Group XXXVIII] To adjust the distance between a magnetic transducer core and an adjacent co-operating magnetic record carrier such as a rotary magnetic drum, not shown, as used in a magnetic computing and storage apparatus, a magnetic transducer head assembly uses the known differential thread principle and comprises a casing 18 containing the transducer core 11 and coil 13 and having an external screw-thread 20, a mounting 33 having an internal screw-thread 35, and a bushing 32 having external and internal screw-threads 36, 37 to connect it to the mounting and casing respectively, the threads 35, 36 connecting the bushing and mounting being of different pitch from those 20, 37 connecting the bushing and casing and the casing and mounting being relatively non-rotatable whereby rotation of the bushing produces axial movement between the casing and mounting. The bushing is of nylon, is knurled at 43, and when assembled its internal thread 38 engages the unthreaded part 21 of casing 18 whereby they are compressed and furthermore the bushing is expanded to press its external threads 36 against those 35 of the mounting 33 to prevent unbidden rotation of the bushing. The mounting 33 has a lug slotted at 42 to secure the assembly to a mounting ring, not shown, and a keyway 40 engaged by a hollowed key 23 in casing 18 to prevent the relative rotation.

Title: Improvements in or relating to electric heating apparatus for buildings and the like
Inventor: HUNT JOSEPH JAMES HOLMES
IPC: F24D13/02
Filed: 1958-03-10
Abstract: 895,738. Mounting electric heating resistances. SIMPLEX ELECTRIC CO. Ltd. March 10, 1959 [March 10, 1958; Oct. 4, 1958], Nos. 7638/58 and 31749/58. Drawings to Specification. Class 39(3) In an electric heating installation for buildings wherein the electric heating element is embedded in a wall, ceiling or floor for space heating, the heating element is mounted on a sheet or on a plurality of strips and the assembly as a whole has a flexibility such that it can be folded or rolled up into a compact form, yet when unfolded or unrolled it is sufficiently stiff to preserve its configuration. The resistance wire has an insulating sheath of PVC or of composite nylon and polychloroprene. The sheathed wire can be secured to the strips by adhesive or by welding. There may be two sets of strips (or sheets) secured together by adhesive or by welding, stitches, staples or rivets with the heater wire between various configurations being described. Fig. 5 (not shown) has a perforated or unperforate sheet. In Fig. 7 (not shown) only alternate tunnels are filled with the heating elements. In modifications the heater elements can be inset from the lateral boundaries. The sheets may be of paper or formed of or incorporating synthetic resin or combinations of paper or fibrous material and synthetic resin the resin forming an impregnating medium or being applied as a reinforcing lamine or metal foil alone or reinforced by a lamine of paper or fibrous material which may if desired be impregnated with synthetic resin. Alternatively the reinforcing lamina may itself be formed of synthetic resin. The heater can be secured to the sheets by adhesive if combinations of paper and fibrous materials are used therefor, or if of synthetic resin the latter is selected so that the wire can be fused to the sheets. The sheets can be connected to one another as can the two sets of strips, e.g. by stitches instead of by adhesive or by fusion.

Abstract: 556,723. Coke-oven doors. KOPPERS CO. June 8, 1942, No. 7812. Convention date, Aug. 13, 1941. [Class 123 (i)] [Also in Group XII] A self-sealing coke-oven door comprises a plug portion 31 and an outer rugged metal supporting back 10 of dished shape having inner side walls with a marginal flange that by adjusting screws 20 regulate the pressure on a flexible sealing member 21, he supporting back being spaced from the plug portion to which it is secured by bolts 15 passing through bosses 13 so that air for cooling purposes may pass freely between the supporting back and the plug assembly. Openings 17 give access to this air which passes upwards and around the levelling door frame 25 which is spaced from the back 10. A thin clamping sheet 48 is secured to lateral supports 35 of the plug 31 by bolts 37 which pass through bars 49 under which the sheet 48 is clamped. The levelling door frame 25 is bolted to the plug assembly out of contact with the supporting back and. projects through an opening 26. Heating up gas may be supplied to the interior of the coking chamber through an opening 54 covered by a plate 55.

Title: Disc brakes
IPC: F16D65/12
Filed: 1973-02-17
Abstract: 1447113 Discs for disc brakes; indicating GIRLING Ltd 15 Feb 1974 [17 Feb 1973] 7909/73 Heading F2E A disc 1 or 1a for a spot-type disc brake has two diametrically opposed portions of the periphery of the disc cut away at 4 (Fig. 2) or chamfered at 5 (Fig. 4) over a circumferential length at least equal to the maximum circumferential of a brake pad, the radial dimension of each cut-away or chamfered portion being such that its radially inner edge is of a radius less than that at which the radially outer edge of the pad 2 is applied to the disc, thereby preventing formation of an axially extending tip 3 over the part of the periphery of the disc occupied by the gaps or chamfered portions. The brake pad 2 can therefore be more easily removed in a radial direction for pad replacement. The disc may be utilised in a brake with opposed hydraulic cylinders in a caliper, or in a reaction-type brake with a slidable bridge member-in the latter case only one face of the disc 1 need be chamfered since once one pad 2 has been removed the bridge member can be so positioned as to allow the removal of the remaining pad. To facilitate pad removal a mark may be provided on the bell of the disc for alignment with a mark on an adjacent fixed part of the vehicle to indicate when one of the gapped or chamfered parts of the disc is in alignment with the brake pad.

Abstract: 1302767 Magnetic storage devices KOKUSAI DENSHIN DENWA KK 20 Feb 1970 [24 Feb 1969] 8183/70 Heading H3B In a magnetic storage matrix, a set of parallel row conductors 2 coated with magnetic material are sandwiched between two sets of column conductors 5, at least one of the latter sets comprising ribbons 6 of conductive material each coated with a thin film of magnetic material 7 except at regions 4 facing adjacent row conductors. The column conductors of a set are held together by insulating material 8, and high packing density may be achieved since the films 7 isolate the column conductors from one another. The structure of Fig. 1 is made by inserting coated ribbons into a grooved carrier 8 and grinding away edges 4, a layer 9 being provided to insulate the rows from each column. Fig. 2 shows an alternative structure where the edges 4 have been etched away to leave an air gap 7a, and a different carrier formed of several spacers 8c is used. In a similar structure, Fig. 7 (not shown), the assembly is mounted on a printed circuit board, the edges of the assembly being cut at an angle to expose to conductors for connection to drive circuitry. An embodiment where only one set of column conductors is coated with magnetic material is also described, Figs. 3-5 (not shown). The coated row conductors may be made by vapour depositing a magnetic strip on to a carrier, vapour depositing a conductor on to the strip, and electrolytically depositing a magnetic film to form, with the strip, a closed film around the conductor. In the above embodiments the easy axis of magnetization of the row conductors is circumferential while in the column conductors it is axial.

Abstract: In forming agglomerates of titaniferous materials for the production of titanium tetrachloride or titanium oxide by static bed chlorination, titaniferous material of 60-120 mesh is mixed with coke of 20-80 mesh and a light tar or tar residuum binder to form an aggregate which is spread out in a relatively thin cake and heated to a temperature above the volatilization temperature of the volatile hydrocarbons of the binder, but not above 400 DEG  C., to burn off the volatile hydrocarbons, and the coalesced aggregate is then cooled.  The titaniferous material may be rutile or ilmenite ore, ore concentrates or a titaniferous slag, the coke may be unground petroleum coke, and the binder may be a tar residuum, pitch or asphalt, but preferably is a light tar, and may constitute substantially 15 per cent by weight of the aggregate.
