Title: Improvements in an Apparatus for Manufacturing a Hose for Taking an Undisturbed Soil Sample
IPC: E21B25/06
Filed: 1968-04-05
Abstract: 1,194,643. Making tubes. STICHTING WATERBOUWKUNDIG LABORATORIUM. 5 April, 1968 [6 April, 1967], No. 16501/68. Addition to 1,143.924. Heading F2P. [Also in Division B2] An apparatus for making a hose by coating a knitted hose comprises a tray 14 for the coating liquid, the tray having an aperture in its base through which a tubular element 20 extends. The tubular element 20 over which the knitted hose is drawn comprises a body of revolution provided with a central bore the upper end of which extends above the tray 14. A tube 22 is mounted within the tubular element 20 to form an annular space in the central bore. The annular space communicates with an air supply, the air in the use of the apparatus passing into the upper end of the tube 22 and through the tube 22 thus keeping the coated tube above the tubular element inflated. A resilient ring 11 is provided in the central aperture of the tray to prevent leakage of coating liquid. In the construction shown the sealing of the resilient ring 11 is aided by providing a pressurized air chamber 9 below the tray. Air passes from the chamber 9 to the annular space through passages 23 in the tubular element. The tubular element may be supported either by rollers 28, one at each side of the tubular element (lefthand half of element in Figure) or by magnetic or electromagnetic means 30 (right-hand side). The knitted hose may be mounted on a pin 3 or the apparatus may be connected to a knitting machine. The apparatus is also provided with heaters and guide pulleys (Fig. 5, not shown).

Title: Wax modified polystyrene compositions and process of manufacture
IPC: C08L25/06
Filed: 1955-06-08
Abstract: In the process for making round records of the parent Specification, the wax and additional polystyrene which is added is obtained by precipitating a mixture of aqueous wax and polystyrene emulsions, drying, and mechanically working at between 160 DEG  and 225 DEG  C., before incorporating in the basic polystyrenecarbide composition. The wax emulsions may be prepared from carnauba, candelilla, montan, esparto, oricury, beeswax, cotton wax, insect wax, japan wax; a synthetic wax made by hydrogenating vegetable, marine or animal oils; or mineral waxes such as paraffin and microcrystalline waxes, ozokerite, or ceresin.  The emulsions may contain zinc stearate and polyethylene glycol oleyl ether.  The polystyrene emulsions may be prepared by polymerizing styrene by heating in aqueous emulsion with a potassium persulphate catalyst, a sodium soap of dehydrogenated rosin, t-dodecyl mercaptan and sodium hydroxide under nitrogen, preferably to give Standinger molecular weights of 40,000 to 150,000. The mixed emulsions may be precipitated by aqueous sodium chloridehydrochloric acid solution, aqueous isopropanol or aqueous acetic acid, and the coagulum dehydrated by exposure to air or heat. The mechanical working is carried out in a heated screw extrusion, Banbury or multi-parallel roller mixer.  The product is diced and blended with fillers, e.g. diatomaceous silica, slate flour and calcium carbonate, pigments, e.g. carbon black and soaps such as zinc and calcium stearates, and moulded.

Title: Dispensers for use in bacteriology and similar biochemical  analysis
IPC: G01N1/00
Filed: 1973-04-06
Abstract: 1471865 Dispensing measured quantities of liquid UNILEVER Ltd 8 April 1974 [6 April 1973] 16735/73 Heading B8N A device for dispensing liquids for bacteriological sampling comprises a reservoir 2 for the liquid, and a dispenser 9 connected to the reservoir via a conduit 3 for liquid, means for applying pressure within the reservoir to three liquid therefrom via the conduit 3 into the dispenser 9, control means for controlling the level to which the dispenser is filled, and dispensing control means for controlling dispensation of a measured quantity of liquid from the dispenser, the reservoir and dispenser being detachable for separate sterilization and the control means and dispensing control means being in the form of externally applied clamps 7, 8 which flatten a flexible pipe coupling. As described the reservoir 2 is a bottle supported in a base unit 1 on which the dispenser body 9 is detachably secured by clips 14. In operation a vibrating diaphragm air pump 11 supplies air to the bottle 2 via a conduit 4, connecting unit 5 and bacterial filter 6. Liquid forced from the bottle passes to the dispenser body 9 via the conduit 3 and a dip tube 15 forming part thereof. When the liquid in the body 9 reaches the level 19 it closes an electrical circuit including an electrode 16 to send a signal to an amplifier 12 which closes a solenoid operated valve 7. A similar valve 8 in an outlet tube 10 of the body 9 is then opened to dispense the measured quantity of liquid, a breather tube 21 with a bacterial filter permitting this. The valves 7, 8 each comprise a wedge acting against a flexible tube portion and are interlocked so that valve 7 must be closed before valve 8 can be opened. The quantity of liquid dispensed may be varied by using electrode 17 instead of electrode 16. The body 9 may be detached by opening valves 7, 8, disconnecting unit 5, opening a plug 13 in the electrical line to amplifier 12, and removing the body from clips 14.

Title: Improvements relating to the control gear of a marine type internal combustion engine
Inventor: GARDNER JOHN KYNASTON
IPC: B63H21/22
Filed: 1960-05-12
Abstract: 900,322. Regulating. GARDNER & SONS Ltd., L. April 27, 1961 [May 12, 1960], No 16761/60. Class 7(6) In a marine internal combustion engine a single hand level a Fig. 1 controls the engine speed and the Ahead, Neutral and Astern positions of the engine drive reverse gear through three plug valves keyed to the spindle b which control a hydraulic cylinder/piston arrangement Fig. 6 to operate the reverse gear, through a rod i; movement of the lever a through a small angle from the neutral position merely operating the reverse gear after which the engine speed control z can be operated from idling to full speed whilst the reverse gear remains in the selected position. For the Astern position of the reverse gear the level a closes plug valves d and e Fig. 6 and causes plug value c to admit pressure oil to the right hand side of the piston h and relieves the pressure at the other side to move the rod i appropriately. During this first small angular movement of the handle a the part t moves along a slot w and when the Astern position is reached abuts the end of the slow w. Further movement of the handle a is translated by a rod y into control of the engine speed or governor lever z. Control of the reverse gear and engine speed for the Ahead position is effected in a similar manner by opposite movement of handle a. Frictional retention of the position of handle a is provided by a pad 10, Fig. 3. The engine lubrication oil may be used as the pressure fluid and by-pass cocks may be fitted in two pipes connected to opposite ends of the cylinder g to make the hydraulic system inoperative without affecting the engine speed control. The hand lever may be remotely controlled from a ship wheelhouse.
