IPC: H01H35/10
Filed: 1962-12-04
Abstract: 1,013,612. Mercury switches. R. K. LE BLONDMACHINE TOOL CO. Dec. 4, 1962 [Feb. 2, 1962], No. 45828/62. Heading H2B. A centrifugal switch 30 for indicating the starting or stopping of a rotating member 40 includes an insulating barrier 52 over which mercury divides during continuous rotation to break contact between slip rings 54, 56 with which mercury pools 62, 64 are in continuous contact. When switch 30 ceases rotation the mercury collects in a single pool 66, Fig. 3, around the barrier 52, after a time delay caused by notches 78 constricting the mercury flow around the barrier. Alternatively an insulating barrier 210, Fig. 14, which divides the mercury into two pools 212, 214 has a peripheral groove 216 communicating via diametrically opposite notches 218, 220, with the two sides of the barrier such that the mercury establishes a connection therethrough only when the switch continuously rotates and the mercury is thrown out as an annular layer inside the switch body. Inert gas is supplied to switch 30 via a hole 68. The slip rings are located in slots in the switch body, or are moulded therein, or themselves define part of the switch body (Figs. 6-13, not shown). The insulating barrier may have apertures through which the mercury meets upon cessation of rotation (Fig. 12, not shown). U.S.A. Specification 3,094,595 is referred to.

Patent GB-461287-A (GB)
Abstract: 461,287. Gravity-separation apparatus. MILLS & CO. (ENGINEERS), Ltd., J., and MILLS, M. W. Sept. 11, 1935, No. 25216. [Class 111] A settling chamber for separating sand, grit &c. from crude sewage has its base curved so that the transverse section is in the form of an arc of a circle and a standing-wave flume, or weir is arranged in the discharge passage from the chamber to control the flow and head of liquid in the chamber so that the crosssection of the liquid in the chamber is proportional to the amount of liquid delivered to it, and the rate of flow therethrough is consequently constant. Fig. 3 shows a crosssection of the settling-chamber b. The settled solid matter is removed through a suction pipe e which oscillates across the chamber and is mounted on a platform d moving on rails d<1> lengthwise of the chamber. The matter drawn up is delivered to a wagon g carried by the platform, which carries also electric motors to move the platform, to drive the suction pump and to oscillate the pipe e. A float h in the sewage controls the mechanism which moves the pipe e to ensure that the end of the pipe does not emerge from the liquid. Fig. 4 shows an alternative means for removing the settled matter, which is lifted by buckets j<3>, pivoted on slowly revolving arms j<1> and tilting to discharge their contents down a trough k<1> to a wagon k which moves with the platform d<x>. An arrangement is described in which a chamber b as described above, is used as an auxiliary settling chamber to treat the thicker matter separated in a preliminary settling-tank.

Title: Method of making self-supporting coils and mandrel therefor
IPC: B65H55/00
Filed: 1961-12-27
Abstract: 952,401. Making coils. INDUSTRIAL RESEARCH PRODUCTS Inc. Dec. 27, 1961 [Dec. 27, 1960], No. 46360/61. Headings B3A and B3E. [Also in Division B5] A method of making a self-supporting coil comprises the steps of winding wire on a mandrel and then pulling the mandrel out of the coil by a force acting axially of the coil for a time and with a force sufficient to contract the walls of the mandrel away from the coil to provide an annular clearance throughout the length of the coil tunnel. A plastic mandrel 10 is formed by injection moulding to the shape of blocks 12, 14, connected by a land 16, having a central transverse stratum of slightly less tensile strength than the rest of the land 16. The mandrel may be formed by casting or machining. The block 12 is then clamped between jaws 24, 26, Fig. 5, of a winding machine and wire 17 is wound around the land 16 and an adhesive 28 which does not adhere to the mandrel is applied thereto. The wire coil so formed may then be pressed between flat surfaces and excess adhesive removed. Heavy wire leads 30, 32, Fig. 7, may then be soldered to the ends of the wire of the coil and lie along grooves 38, 40 or holes in the block 14. The mandrel and coil are then mounted in a jig, 37, Fig. 9, and coated with an imbedment compound 41, Fig. 13, which may be the same as the adhesive 28. The adhesive 28 and imbedment compound 41 is cured or set and the coil and mandrel stripped from the jig 37. The block portions 12 and 14 are then clamped in jaws which pull apart so as first to stretch the land 16 of the mandrel and cause it to contract away from the wire windings and then to cause the mandrel to break into two at 54. The mandrel may be of polyethylene, acetyl, acrylic, chlorinated polyether, nylon, polypropylene, styrene, polycarbonate, polychlorotrifluoroethylene, fluorocarbon, vinyl plastic, or polytetrafluoroethylene.

Title: Draft sensing apparatus for tractor
IPC: A01B63/112
Filed: 1974-10-28
Abstract: 1493379 Tractor draft sensing apparatus MASSEY-FERGUSON SERVICES NV 28 Oct 1974 [29 Oct 1973] 46583/74 Heading A1P A tractor draft-sensing apparatus comprises an elongated shaft 17 mounted on spaced fulcrum supports 19, draft means 5 connected to the shaft at points spaced from the supports whereupon forces on the draft means cause the shaft to bend, sensing means responsive to bending of the shaft and including an elongate member 27 attached at one end to the shaft and arranged to extend generally parallel to the shaft, means for measuring the relative movement between the shaft and the other end of the elongate member resulting from bending, and an arrangement for limiting the relative movement in a first plane whilst allowing the relative movement in a second plane. In the preferred embodiment the shaft 17 has cylindrical end portions 17a joined by an intermediate portion 17b being of smaller dimension in the horizontal plane than in the vertical plane. The other end of the elongate member 27 engages the shaft via a cam system which senses bending of the shaft in the horizontal plane only. The cam system comprises a roller 31 engaging a cam surface 35 on a cam member 33 rotatably carried on the shaft 17 and pivotally connected at its outer end to a link rod 37 transmitting movement of the cam member to control mechanism C against the action of a spring 39. Mounted on the shaft 17 is an elongate arm 40 having a horizontal slot 42 into which the roller 31 extends. The slot 42 permits fore and aft movement of the roller 31, and the member 27 relative to the shaft 17 but prevents vertical movement therebetween. Rotation of the member 27 and the arm 40 about the shaft 17 is prevented by a pin 44 extending from a hole in the housing 15 into a slot 46 in the arm 40. Under the action of horizontal forces the shaft 17 bends but the member 27 remains straight thereby operating the cam system and the control mechanism C to adjust the height of the draft links 5. Under the action of vertical forces both the shaft 17 and the member 27 bend and no net change in the height of the draft links 5 results.

[Also in Division B6] Apparatus for bending the tip end of a series of artificial Christmas tree limbs passing through the apparatus comprises (Fig. 9) an endless belt 216 supported by two spaced pulleys 208 and 210. The pulley 208 is mounted for free rotation about a horizontal axis and positioned above the driven conveyer belt 134. The pulley 210 is supported for free rotation about a vertical axis, is slightly inclined from the horizontal and positioned below the conveyer belt 134. The tip section 114 of the tree limbs moves into contact with the belt 216 at contact point 218 and is bent downwardly since the belt is moving downwardly and at the same time changing from a generally horizontal position to a vertical position. Apparatus for bending the inner end 115 of the same limb in the opposite direction to the bend given to the tip end 114 comprises upper and lower axially spaced, overlapped notched wheels 230 and 232 (Fig. 7) which are positively driven in opposite directions at a speed which is co-ordinated to the velocity of the conveyer belt carrying the spaced limbs by a flexible drive means coupled directly to a driven pulley associated with the driven conveyer belt. The periphery of the upper wheel at the bottom thereof is in line with the upper run of the conveyer belt 136, and the wheel locates the inner end 115 of the limb adjacent the bend point 117 while the bending is achieved by the smaller overlapped wheel 232. The extent of the bend is determined by the axial spacing Y between the wheels and the vertical overlap between the wheels.

Title: Improvements relating to magnetic thin film memories
IPC: G11B11/105
Filed: 1967-10-19
Abstract: 1,133,919. Magneto-optical data storage. INTERNATIONAL BUSINESS MACHINES CORP. 19 Oct., 1967 [10 Nov., 1966], No. 47554/67. Heading H3B. Data stored in a magnetic garnet thin film is read by directing a beam of polarized light, having a wavelength less than 5000 A, on to the storage location and detecting changes in the polarization of the beam caused by the stored data. The film preferably consists of gadolinium iron garnet, less than 2 microns thick, and preferably 0À2 micron thick, mounted on a transparent substrate. The film is maintained at its compensation temperature in a magnetic field which is incapable of switching the magnetization direction of any part of the film at the compensation temperature. To store data polarized light, e.g. from a zinc oxide laser or from a gallium arsenide laser associated with a frequency doubler, is directed on to a selected region of the film by means of an optical deflector, and raises the temperature of this region. The magnetic field is then sufficient to switch the magnetization in this region to store a " 1," for example. If a " 0 " is to be stored either the light beam or the magnetic field is suppressed, or the field is reversed. During read out the magnetic field is switched off and the film is scanned more rapidly to reduce to heating of the storage sites. The reading process may utilize either the Faraday effect, whereby the plane of polarization of the beam is rotated, or the circular dichroism of the film, whereby one of the circularly polarized components of the incident beam is absorbed more than the other, depending on the direction of the remanent magnetization in the storage region.
