Abstract: 596,232. Dental articulators. TAYLOR, G. C. Nov. 29, 1944, No. 23759. [Class 81 (ii)] A method of making artificial dentures includes the step of moulding the model of the relevant part of the patient's mouth around one end of a plate so that the end is anchored in the model, the opposite end of the plate having a portion adapted to be clamped in an articulator to permit adjustment of the plate angularly with respect to the clamping means about an axis disposed at or near the clamped end of the plate and disposed transversely of the length of the plate, the moulding step being performed during the formation of the model itself against an impression taken from the patient's mouth. The articulator comprises a base 10 formed with a clamp 7 having a cylindrical seating 12 for the cylindrical portion 9 of the lower plate 8, the two halves of the clamp being urged apart by spring 16. A spigot 11 on the base carries a post 20 which may be locked in any position of rotation by tightening screw 24 carried by split clamp 22. This is retained in the post by screw 21. The upper end of post 20 is forked to carry a head 26, the movement of which about pivot 27 is limited by an adjustable stop 28. The upper clamp 34 for plate 42 is formed with a cylindrical stem 33 which is slidably and rotatably mounted in a bore in the head 26, and which may be clamped by tightening screw 37 in a split clamp 35. The seatings in clamps 7, 34 and the corresponding parts of plates 8, 42 may be ribbed or grooved as shown, and the remaining parts of the plates, which are forked, may be formed with projections to improve anchorage.

IPC: B65G49/04
Filed: 1953-08-28
Abstract: <PICT:0751012/III/1> Articles 10 to be treated, e.g. degreased, cleaned and painted, by being dipped in tanks 11 are supported by members 13 which are suspended from an endless chain constructed as described in Specification 639,244 [Group XXX] and guided around a track 12. This track is suspended from a platform 19 supported by pillars 17, by means of chains 23 which are secured at one end to girders 16 connecting the long sides of the track and pass round chain wheels 22 adapted to be driven through gearing by an electric motor 20 whereby the track may be guided by rollers 18 up and down the pillars 17 so that the articles are moved into and out of the tanks 11.  The conveyer chain is driven by a driving unit as described in Specifications 665,883 [Group XXV] and 665,888 [Group XXX].  When the articles are in register with the openings 26, an arm 29 on the member 13 of the leading article engages the operating member 28 of a switch 27 where the conveyer driving unit is arrested and the hoisting motor 20 is started so as to effect lowering the track.  When the articles are immersed to the requisite depth within the tanks, a trip switch 30 is engaged by the left-hand girder 16 whereby the hoist motor is stopped and a reversing switch 31 operated to effect reversal of the motor and so bring the articles clear of the tanks.  Immediate re-starting of the hoist motor is prevented by a time switch 25 which is set by the operator so as to maintain the articles for a pre-determined time within the tanks.  When the track is fully raised, a trip switch 32 is operated so as to stop the hoist motor and start the conveyer driving unit 24.  The tanks 11 may be re665,887 and 737,265 [both in Group XXX] also are referred to.

Title: Improvements in or relating to the construction of "in situ" concrete piles
IPC: E02D5/52
Filed: 1931-08-24
Abstract: 370,795. Concrete piles. HOOD, A., 181A, Adelaide Road, Hampstead, London. Aug. 24, 1931, No. 23805. [Class 68 (i).] In making concrete piles in situ, a hole is bored and lined, hollow pre-cast units are inserted in it, and grout is supplied under pressure to the hollow core, the lining being withdrawn before or as the grout fills the hole. As described in connection with the Figure, a boring is made to the firm stratum 3, and a steel casing 4 is sunk in it. A solid pre-cast toe unit 5 is then placed at the foot of the casing, and the pile is built up by lowering a succession of hollow reinforced concrete units 6 with parts 7, 8 forming spigot joints which are completed by pouring grout into the recesses 9. This grout flows through passages 10 into the casing 4. Pressure is then applied to the pile by a hydraulic jack 12 set between two I-section beams 13 and a helmet 17. The beams 13 are connected by rods 14 to a collar 15 on the casing 4, which is thus withdrawn as the pile is pressed down. A sectional pipe is then lowered through the bore 6a and grout supplied while the casing 4 and the pipe are both lifted. Before the casing 4 is completely extracted pressure is again applied by means of the jack. A steel rod is then forced down the grout in the bore 6a, part being left projecting.

Title: A bath and process for depositing a film of magnetic material on a substrate
IPC: C23C18/36
Filed: 1965-06-04
Abstract: A magnetic Co film is electrolessly deposited on a substrate (e.g. of glass, ceramics, plastics such as polyethylene terephthalate, or of metal) from an aqueous solution of a Co salt, a hypophosphite such as sodium hypophosphite and a material which produces malonate ion in solution. A predetermined coercivity can be obtained by appropriately selecting the concentration of the malonate ion.  The Co salt may be a chloride, sulphate, acetate or sulphamate, and the malonate may be malonic acid.  The solution may contain the ammonium ion added e.g. as (NH4)2 SO4 and NH4OH.  The pH is maintained at 8 to 11 by adding hydroxides, e.g. NH4OH, and ammonium salts such as (NH4)2SO4 or NH4Cl.  The substrate may be a tape drum or disc.  In an example a polyethylene terephthalate web is mechanically roughened, chemically etched and then sensitized by exposure to a Sn Cl2 solution and then to a Pd Cl2 solution with a water rinse after each exposure.  The sensitized web, at this time having Pd on its surface, is then electrolessly coated with the Co.  The coating bath may comprise:- .cobaltous ion.3.75 - 15.0 grams/litre .hypophosphite ion.3.0 - 24.5 grams/litre .malonate ion.15.0 - 200.0 grams/litre .ammonium ion.1.0 - 100.0 grams/litre

Title: Improvements in or relating to bleaching of oils
Inventor: MCMICHAEL CHARLES EDWARD
IPC: C11B3/10
Filed: 1953-09-04
Abstract: <PICT:0737965/III/1> Fatty oil, such as cottonseed oil or soya bean oil, is bleached with an adsorbent, such as carbon black or bleaching clays, e.g. fuller's earth, by subjecting the oil in a first stage to the action of partially spent adsorbent, mixing the partially bleached oil in a second stage with fresh adsorbent, and separating the partially spent adsorbent therefrom for use in bleaching additional oil in the first stage, a small portion of oil being mixed with the fresh adsorbent to form a slurry to be used in the second stage.  The adsorbent and the oil to be treated are both preferably de-aerated and dehydrated by stripping with steam before contact with each other.  In a suitable plant, the oil to be bleached is pumped through a supply pipe 13 to a spray nozzle 14 in the upper part of a lower chamber 10 of a treatment vessel 9 where it is steamed with steam from a perforated pipe 15, and is then withdrawn at the bottom and pumped through a heat exchanger 17, a heater 18 and then delivered to one of the filters F1, F2, F3, F1 being shown in use. The filter contains a mass of partially spent adsorbent and the oil is thus subjected to the first stage bleaching.  The oil then flows through pipe 19 to an oil inlet 20 located below a body of oil in the bottom of an upper chamber 8 of the treatment vessel 9.  Here the partially bleached oil is mixed with a slurry of the oil and fresh adsorbent, supplied to a spray nozzle 7 from a mixing vessel 4, for the second stage bleaching.  The oil and slurry are then withdrawn from the upper chamber 8 through a pipe 21 and pumped to the filter system, F2 as shown, for separation of the partially spent adsorbent from the oil.  The fully bleached oil is then discharged through line 23, heat exchanger 17, and cooler 25 to storage.  The filters are used in rotation.  The compartments of the vessel 9 communicate through a stand pipe 12 and the upper chamber has a vacuum offtake 15 so that both the fresh oil in the lower chamber and the slurry in the upper chamber are steam-stripped under vacuum.  A perforated steam pipe 27 and a heating coil 28 may be provided in the upper chamber 8. The oil is heated in the heater 18 to an effective bleaching temperature of about 250 DEG  F.  The oil for the slurry may be the unbleached oil, the stripped oil or the final bleached oil. Specification 700,234 is referred to.
