Title: Improvements in larvicidal preparations
IPC: A01N25/04
Filed: 1943-04-12
Abstract: Hydroquinone is employed as an antioxidant for preserving pyrethrins present as toxicants in larvicides comprising a stable disperse system of oil in water, some of the oil particles being lighter than water and some heavier than water, and the disperse phase containing an emulsifying agent.  Specifications 493,074 and 547,927, [Group VI], are referred to.ALSO:A larvicide comprises a stable disperse system of oil in water, some of the oil particles being lighter than water and some heavier than water, the disperse phase containing an emulsifying agent and the oil particles of both groups being toxic to larvae by virtue of the nature of the oil and/or by virtue of a toxicant dissolved or dispersed in the oil.  The oil which is lighter than water may be mineral oil such as kerosene or a slightly heavier oil sold by the Shell Oil Company under the name P31, or that sold as Wakefield's water white oil.  The oil which is heavier than water may be one which is miscible with the lighter oil, such as nitrobenzene or carbon tetrachloride, in which case the preparation is made by mixing separately prepared emulsions of the oils in water; or the heavier oil may be one which is immiscible with water lighter oil, e.g., dimethyl phthilate when the preparation may be made by a single emulsification.  The following toxicants may be added:-pyrethrins, rotenone, organic thiocyanates, fenchyl thiocyanoacetate or p-dichloro-diphenyltrichlorethane.  The emulsifying agent may consist of an oil-soluble components, e.g., cholesterol, cetyl alcohol, oleyl alcohol, mixed secondary alcohols (C10-C18), geranium oils or essential oils, and a water-soluble component, e.g., sodium cetyl sulphate, sodium oleyl sulphate, hexadecyl trimethyl-ammonium bromide, hexadecyl pyridinium bromide or the sodium salts of cresylic and oleic acid. Alternatively composite emulsifying agents such as a long chain ester of glycerine or a glycol, a sulphuric ester of a long chain secondary alcohol or a non-ionogenic fatty condensation product may be employed.  Certain of the specific examples also comprise prepared chondrus as a hygroscopic agent, hydroquinone as an antioxidant for stabilizing pyrethrins, methylcyclohexanol as an oil-soluble stabilizing agent and tetralin as a supplementary solvent.  Specifications 493,074 and 547,927 are referred to.

IPC: H03K7/02
Filed: 1953-03-03
Abstract: 748,278. Pulse code modulation circuits. GENERAL ELECTRIC CO., Ltd. June 3, 1954 [March 3, 1953], No. 5956/53. Class 40 (5). For sampling a varying signal voltage applied to a cathode follower stage 1, the cathode is periodically connected to a storage capacitor 4 through a diode switch 5 rendered conducting by a pulse applied to the primary 11 of the transformer 7. To avoid cross-talk &c., the valve 1 is normally held non-conducting by a positive voltage from voltage divider 26, 27, 29, applied to its cathode through rectifier 25, but which is cut off during the pulse by rendering the diode non-conducting by a pulse from the secondary 12 of the transformer 7. In a modification, the cathode resistance of stage 1 is common to a second triode which normally is conducting but is cut-off during the pulse, Fig. 2 (not shown). The sampler may feed the coder of a pulse code modulation system.

Filed: 1930-02-25
Abstract: 346,527. Ventilating systems. NEILSON, T. and MARSHALL, J., 11, Cogan Street, Pollokshaws, Glasgow. Feb. 25, 1930, No. 6180. [Class 137.] Air, treating ; controlling ventilation ; forced ventilation.-A flow of air for ventilation is conditioned by cooling it to a dew point corresponding to the relative humidity finally required, saturating it with water vapour at this temperature, and heating it by indirect contact with incoming air, which is thereby preliminarily cooled. Air drawn by a fan 6 from a room 1 mixed with fresh air from a conduit 4 passes through a conduit 5 to a heat exchanger 7. The amount of air entering at 4 is regulated by a valve 13 operated by a thermostat 16 in the room. The air then passes through conduit 8 to a refrigerating coil 10 controlled by an adjacent thermostat 18. The air is thus cooled to the desired dew point, and liquid drops entrained are separated at 11. The air is then heated by incoming air in the heat exchanger 7 and enters the room by conduit 8e. When required, the conduit 5 is closed and atmospheric air drawn in at 15 is heated at 12 and passed directly into the room, the valve 14 being suitably adjusted. Steam may be added at 28 to an extent controlled by a humidostat 17 in the room. Also, by moving valve 13 to a position 3 atmospheric air from the conduit 4 passes through the heat exchanger 7 to the fan 6, conduit 8, cooler 10, water separator 11, heat exchanger 7 and conduit 8e to the room, whence it returns to atmosphere through conduits 2, 27. The heat transfer unit comprises a nest of tubes fitted between endplates in one conduit and across another.

Title: Improvements in or relating to recording apparatus
Filed: 1932-03-01
Abstract: 398,214. Recording apparatus. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, and CHELIOTI, G., Osram G.E.C. Lamp Works, Brook Green, Hammersmith, both in London. March 1, 1932, No. 6249. [Class 106 (iv).] One recording-apparatus is successively connected to each of a number of devices influenced by the conditions or operations to be recorded, the apparatus comprising marking means, means for operating the marking means, and a control device successively associated with the said devices to determine whether or not the operating means shall be effective in actuating the marking means. In the embodiment shown, the apparatus is adapted for recording the results of burning-time tests on electric lamps. The record drum 11 is driven by a shaft 14 which also drives through a screw 16 a carriage 18 to which is pivoted the recording arm 15 pressed towards the drum by a spring 21 but normally withheld therefrom by a cam 22 and a controlling latch 23. Each lamp has a resistance 24 in its circuit, each resistance being connected through an amplifier 25 to an electromagnet 26. An arm 12 secured to the shaft of the drum makes contact with each resistance circuit in turn. If the corresponding lamp is alight, the potential difference across its resistance energizes the magnet 26 so that the circuit to a magnet 27 may be completed when a rapidly-rotating cam 28 closes contacts 29, the control latch 23 then being moved to release the arm 15 to make a mark. The arm is restored by the cam 22. The drum may be given an intermittent motion, in which case the contacts 29 are unnecessary. In other embodiments, photo-electric cells may be employed as the elements sensitive to the changes to be recorded.

Headings F2Q and F2V A secondary gear unit for use in conjunction with a primary gear unit 31 adapted for mounting on a fluid valve 1 allows either a direct or a reduced drive to the primary unit, and can provide an impulse torque for unseating a firmly seated valve or for seating firmly a valve. The casing 56 of the secondary gear unit is mounted on a flange 38 of the primary gear unit 31 by means of a plate 46 and an adaptor 42. A coupling member 48, splined to one end of a shaft 44 rotatably supported in the flange 38 by a bearing 39 having an adjusting bush 41, has a tooth or lug 49 engaging with a wide slot in one end of a sleeve 51, supported by bearings 50, 58, to form a lost-motion coupling. A bevel gear ring 54 fixed to the sleeve 51 meshes with a bevel gear 74 on a shaft 73, 83 carrying a hand wheel 84. A pipe-thread bore 61 in the casing 56 may either be closed by a plug or may receive a bush 64 holding a bearing 66 for a shaft 62 coupled at one end 63 to the shaft 44 and having the other end 67 squared and projecting outside the casing 56. Oil seals 57, 59, 65, 82 are provided. The drive from the shaft 44 is conveyed by a bevel gear 45, a large bevel gear ring (not shown) in the primary unit 31, a driving sleeve 35, an adaptor 8, and a yoke sleeve to the valve. To unseat a valve, the hand wheel 84 is turned until one edge of the slot in the sleeve 51 impacts against the lug 49 to impart an impulsive torque to the valve. Thereafter a manual or motor drive may be applied to the end 67 of shaft 62 to rapidly operate the valve. Specification 930,489 is referred to.

Title: Improvements in or relating to devices for removing metal from a workpiece
IPC: B23H7/18
Filed: 1959-02-24
Abstract: 896,828. Electro-erosion. PHILIPS ELECTRICAL INDUSTRIES Ltd. Feb. 24, 1959 [Feb. 27, 1958], No. 6329/59. Class 83 (4). [Also in Group XXXV] In a control system for a spark-erosion device 1 for removing metal from a workpiece 8, an electromagnetic element 18 driving the device is fed with energizing pulses of a lower frequency than the spark discharge frequency and after each pulse is energized as a function of the mean electrode current so that an electrode 5 is brought to a position a small distance from the workpiece during the time sparking occurs. The electrode 5 is held by a spring 6 carried on a member 4 movable against frictional restraint along guides 3. On connecting the device to a supply 9 a relay 14 is energized to close contacts 32 and energize the electromagnetic element 18 and pull up the electrode 5 against the action of the spring 6. After an interval determined by a relay 20 shunted by a capacitor 21, contacts 19, 22 change over and the relays 20 and electromagnetic element 18 are energized by the voltage drop across a resistor 12 carrying the mean discharge current between the electrode 5 and the workpiece 8. When the gap is too great for a spark-discharge to take place the electromagnetic element releases the electrode 5 and the impact of an abutment 7 on the member 4 drives the assembly towards the workpiece. This sequence is repeated until a discharge occurs and the electrode is pulled away from the workpiece by a current flowing through the electromagnetic element 18 proportional to the mean discharge current. As erosion takes place the mean discharge current falls and the spark gap decreases until further movement is prevented by the abutment 7 touching the movable member 4. Relay 20 then releases, contact 19 opening and contact 22 closing so that an impact takes place to lower the member 4 and advance the electrode towards the workpiece. The spark discharge frequency is determined by the capacitor 11 and a charging resistor 13. The discharge current through the resistor 12 is smoothed by a capacitor 10. When the electrode sticks to the workpiece, the relay 14 is deenergized and a high current flows through the electromagnetic element 18 to charge a capacitor 34 and pull the electrode away from the workpiece. Specification 800,061 is referred to.

Filed: 1972-02-10
Abstract: 1324582 Tube joints ROBERT KARST 10 Feb 1972 [10 Feb 1971] 6330/72 Heading F2G In forming a joint between a cylindrical spigot and a tube 1, e.g. a telescopic radio aerial, a clamping wire 16 is deformed radially inwardly, so that the ring and the tube are seated in a first portion 14 of a recess and the ring overlies a second portion 15, without touching it. The free part of the ring is thus held under residual stress to maintain the tube wall clamped against the surface of the portion 14. Instead of a solid metal spigot, the spigot may be constructed from an injection moulded plastics part (18, Figs. 3-10, not shown) and a stamped out metal part (22). The tube 1 makes electrical connection with opposing surfaces (24, 28) of part (22). Indentations (30) engage a balldetent to allow angular adjustment of the aerial.
