Title: Device for giving warning of excessive deviation of a craft from a predetermined heading
IPC: G05D1/02
Filed: 1957-08-01
Abstract: 886,423. Radiation sensitive devices. COWELL, R. E. Oct. 31, 1958 [Aug. 1, 1957], No. 24465/57. Class 40(3). An instrument for use in a manoeuvrable craft for monitoring the operation of a gyroscopic direction-defining instrument used during manual or automatic steering of the craft comprises two relatively rotatable members, the first of which is stabilised against turning movements of the craft by means including a device responsive to the Earth's magnetic field, and the second of which is rotated relative to the first by said turning movements, one of the members being settable to a predetermined angular position relative to the other member, and means responsive to relative angular displacement between the two members to energise a visual or audible warning device when said angular displacement exceeds a predetermined magnitude. As shown, Fig. 1, the card 5a of a magnetic compass 1 has a sector 6 cut away near the periphery, the sector subtending an angle of 20 degrees at the centre of the card, i.e. 10 degrees each side of the North point. A hooded lamp 10, mounted on a wheel 12 below the compass, is maintained opposite a photo-electric cell 11 mounted on a ring 13 above the compass, thewheel 12 and ring 13 being rotatable together by a knob 20 on the upper end of a shaft 19 on which are mounted pinions 17, 18 meshing with gear teeth cut in the peripheries of wheel 12 and ring 13 respectively. When the craft's course is set, knob 20 is operated until light from the lamp 10 impinges on cell' 11 through the centre of cut away sector 6; to facilitate this a suitable scale may be provided on the upper surface of ring 13 to co-operate with a fixed index mark The output of cell 11 is amplified in an amplifier 29, Fig. 2 (and possibly in a pre-amplifier on ring 13), and used to heat the heating coil 28 of a bimetallic device 27. Any deviation of the craft's head from the set course of more than 10 degrees interrupts the flow of light to cell 11 thus causing the bimetallic device 27 to cool and, unless the deviation is transient, to close contacts 26 in an alarm circuit containing a bell or hooter 10, a warning lamp 22 in series with an interruptor 23, and a manual switch 24 which is normally closed. To prevent the cell 11 from being energised by reflected light it is provided -with a hood 30 and flange 31, both painted matt black. In modifications, the compass card may be radially extended over one sector so that the light from 10 does not reach cell 11 while the craft's heading is correct; or the cell may respond to light reflected from the card; infra-red radiation may be used instead of visible light, the cell 11 being replaced by a thermo-pile or a thermally controlled relay, or a source of weak nuclear radiation on the card may co-operate with a detector which moves with the craft.

[Also in Division E1]  In rods for mineral drilling operations, individual interconnected tubular sections 1 each have an integral polygonal, e.g. quadrangular, sectioned female coupling part 2 at one end and an axially bored corresponding polygonal sectioned male coupling part 3 protruding from and welded in the other end, respectively, for engagement with the male and female parts of adjacent sections, a spring-loaded snap-pin 8 in each part 3 is engageable with a hole 9 in a mating part 2, and to stabilize and seal each coupling the end 5 of each part 3 is made cylindrical over a length greater than its diameter to accurately fit a corresponding cylindrical bore 6 adjacent a mating part 2 and a sealing ring 10 is provided in a groove in the bore 6 or, as shown, the end 5. The snap-pin 8 is retained by a ring 11 and provided with a sealing washer 12. As shown, a helical smoothing rib 7 is wound round the section and welded thereto at both ends. The drillings produced at the bottom of the borehole may be moistened during drilling to produce a non-flowing slurry which is fed to the borehole mouth by the rib 7. As shown, a small transverse bore 13 may be provided in the polygonal part 3 to permit a controlled small quantity of liquid to be added to the drillings drying out during transportation. Drilling may be initially without flushing medium so that the drillings are moved only by the smoothing rib, a flushing medium such as water or air being used later. The sections of Fig. 4 (not shown) dispensing with the smoothing rib are used where a smooth borehole wall is not needed.

Abstract: 1,137,828. Controlling looms. ELITEXZAVODY TEXTILNIHO STROJIRENSTVI OBOROVE REDITELSTVI. 2 June, 1966 [4 June, 1965], No. 24644/66. Heading D1E. A loom is driven by a reversible electric motor through a clutch and brake operated by an electromagnet controlled by a circuit including relays, a timing switch driven by the loom, and three pushbuttons marked START, STOP, and REVERSE. A D.C. operating voltage and a lower holding voltage are provided for the relays and an A.C. supply is provided for the contactor controlling the motor, which is left running continuously. The arrangement is such that when the STOP button is pressed or the warp stop motion operates, the timing switch brings the loom to rest at back centre, but the other stop motions bring the loom to rest before beat up. The loom can be turned forward for one revolution by pressing the START and STOP buttons in succession and keeping the latter depressed until the loom stops again at back centre. When the loom has stopped in another position, it can be returned to back centre by pressing the REVERSE button; the loom is then declutched at back centre by the timing switch, but the motor continues to run in reverse until the button is released, when it reverts to forward running. To enable the loom to be turned forwards or backwards, the warp and weft stop motions are shorted on operation of the pushbuttons, but if the loom is stopped by the shuttle stop motion it cannot be started until the shuttle has been pushed into the box.

Title: Manufacture of poly-halogen derivatives of pyrene and of pyrene quninones
IPC: C07C25/22
Filed: 1933-09-11
Abstract: Polyhalogen pyrenes are obtained by the action of excess of chlorine on halogen-pyrenes containing 4--6 chlorine or bromine atoms. Polyhalogen-hydropyrenes are initially obtained and hydrogen halide is eliminated to give polyhalogen derivatives.  By oxidation of these products with mineral acids, polyhalogen pyrene quinones are obtained.  According to examples; (1) tetrachloropyrene, obtainable by chlorinating in trichlorobenzene, is treated with chlorine at 100 DEG  C. to give a tetrachloropyrene tetrachloride, the product heated at 300 DEG  C., to give off hydrogen chloride with the production of hexachloropyrene, also obtained by treating the tetrachloropyrene tetrachloride with quinoline or alcoholic potash at 100--130 DEG  C.; the hexachloropyrene gives on treatment with nitric acid at ordinary temperatures, 2 : 5 : 7 : 10-tetrachloropyrene-3 : 8 quinone, which may be converted into a quinhydrone with hydrosulphite, and a dichloronaphthalene 1 : 4 : 5 : 8-tetracarboxylic acid and its anhydride, by strong oxidation; the hexachloropyrene gives a chloropyrene quinone on treatment also with fuming sulphuric acid; the same product is obtained by treating the tetrachloropyrene tetrachloride directly with fuming sulphuric acid; (2) tetrabromopyrene, obtainable by brominating in nitrobenzene at ordinary temperatures to--150 DEG  C., is treated with chlorine in trichlorobenzene at up to 120 DEG  C. to give a polybromopyrene polychloride, which on heating at 300 DEG  C. or in a solvent or with basic agents gives a polybromo-chloropyrene with evolution of hydrogen bromide; (3) hexachloropyrene may be further chlorinated in presence of iodine at 0 DEG  C. to give a perchloropyrene which decomposes on heating at 300 DEG  C. to give a decachloropyrene, this yielding, on oxidation with nitric acid an octochloropyrene-3 : 8 quinone; (4) octochloropyrene obtainable as a bye-product in the preliminary chlorination of pyrene, is oxidized with nitric acid to give a hexachloropyrenequinone.  The oxidation products such as those of example 1 may be used from the manufacture of naphthalene vat-dyes and the quinones may be converted by the exchange of chlorine with amino compounds, into vat dyes.
