[Class 120 (ii)] In rove-stop mechanism for spinning, doubling and like machines of the kind wherein the rove is gripped and the feed rollers separated by means operated by a continuously moving member when moved by a detector lever upon breakage of a thread, a counterbalanced intermediate lever connected with the rovegripping and roller-separating means is moved by the detector into the path of an oscillating member, and a pawl and catch-plate mechanism for operating the oscillating member is arranged to be manually disconnectible during doffing. Retaining means are provided for holding the rove-gripping and roller-separating means while the thread is being pieced. A detector lever 2 pivoted at 2b and adjustably weighted at 2<g> is adapted by means of a stud 2d, to move an intermediate counterbalanced lever 4 into the path of a catch 13 on an oscillating shaft 14 whereby a lever 5, upon which the lever 4 is mounted, is moved about its pivot 6 and closes a rove-gripper 8<c> and raises the feed roller lever 10 by means of a pin 5<f>. A catch lever 9 attached to the lever 5 engages a stop 9<b> and holds the parts in position during piecing. The shaft 14 is oscillated from a continuously rotating crank pin 17<c>, Fig. 3, by means of a connecting-rod 17b and a plate lever 19 carrying a pawl 21 and a projection 21b which are adapted respectively to engage a catch 20<a> and a projection 20<b> on a plate 20 keyed to the shaft 14. The pawl is raised to interrupt the transmission as desired during doffing, by means of a cam plate 22 operated manually through a rod 22<a>, shaft 30 and hand lever 22d. An adjustable stop-stud 20<c> is adapted to engage the plate 20, and determines the forward position of the catches 13.

Title: A lubricating oil composition
IPC: C10M161/00
Filed: 1965-04-27
Abstract: A method of lubricating the cylinders of engines with separate cylinder and crank-shaft lubrication which comprises supplying to the cylinders a lubricating oil composition which in addition to a lubricating oil or a mixture of lubricating oils, and a dispersed salt and/or hydroxide of an alkaline earth metal, also contains at least one oil-soluble polymer without polar groups and which has been prepared by polymerization of at least one olefinically unsaturated compound.  The base oil may be a distillate or residue, or a mixture thereof; the salt or hydroxide may be of calcium, strontium, barium or magnesium, carbonates and carboxylates being preferred, and an alkaline earth carboxylate, e.g. a naphthenate or sulphonate, may be added as stabilizer.  The polymer may be a homo- or co-polymer of a mono- or di-olefin, vinyl or allyl ester, vinyl ether, or unsaturated ester; or a polymer of a polar compound subsequently treated to eliminate polar groups, e.g. a polymer containing acid units which are subsequently esterified, or one containing hydroxy groups which are subsequently esterified.  Non-polar polymers may also have an after-treatment provided that that this does not introduce any polar groups.

Abstract: 1510693 Monitoring drill pipes HOMCO INTERNATIONAL Inc 29 April 1975 [29 April 1974] 17792/75 Headings G1M, G1N and G1S Apparatus for locating the position 10, Fig. 1, where a drill pipe P is stuck in a bore hole B comprises a sensor S lowered by a wire W into the pipe as part of a string of units including an upper bowspring U and lower bowspring G, the sensor consisting of an upper magnetic circuit formed by stator cores 60, 64, Fig. 8, and rotor core 66, determining the inductance of an upper coil 70, and a lower magnetic circuit formed by stator cores 62, 64 and rotor core 68, determining the inductance of a lower coil 72. The cores 60, 62, 64 are attached by upper bowspring U to a first point of contact with pipe P, and the rotor cores 66, 68 are mounted on a ferromagnetic rod 154a which is attached at its lower end to a second point of contact with pipe P via lower bow spring G. The portions of the string of units carrying the bowsprings U, G include a flexible section which is contracted when the probe assembly is lowered into the pipe, enabling the rod 154a and the rotor cores to be clamped. When the sensor S is located at the pipe sticking point a tension applied to the support wire W releases the rod 154a, and the rotor cores 66, 68 assume a predetermined angular position relative to the stator cores 60, 62. The tension on wire W is slightly relaxed, allowing the switch contact 78 to be earthed, and a stress or torque is applied to the pipe P to produce a differential change in the inductances of coils 70, 72, since the upper bowspring U is moved and the lower bowspring G is in contact with a part of the pipe that is stuck. The coils are fed with alternate half cycles of the output of an oscillator 26, and the resulting D.C. unbalance is smoothed at 34 and indicated at 38 at the surface equipment M. An increased tension is then applied to the support wire W to changeover switch contacts 78, 80 enabling a current from circuit C to be fed via switch K to a detonator D which explodes to release the pipe P. In a modification to avoid errors due to the formation of local electro-chemical EMF's in the presence of salt water in the borehole, the unbalance signal from the probe S-3, Fig. 14, is fed through a high pass filter 416 to peak detector 420 to charge capacitors 425, 428 in the alternate half-cycles. The resultant D.C. voltage across potentiometer 430 is amplified and shown on meter 38. The borehole probe may also include a ferrous mass detector, a temperature sensor and an inclinometer.

Abstract: 1,269,556. Liquid filter. B. D. BOHNA & CO. Inc. 8 April, 1969 [15 April, 1968], No. 17970/69. Heading B1D The useful surface area of a sand bed filter is extended by an array of flat distributing elements in the form of cloth bags 22 filled with coarse material 24 and extending vertically from the fine filtering medium 14 into the body of unfiltered liquid 30 above, so that filter cake 38 forms on the top of medium 14 and along the surfaces of the bags. The liquid is delivered to the body 30 by side nozzles (32) and is cleaned in passing a short distance into medium 14, and then percolates down into a coarse supporting layer (16) (Fig. 2, not shown). Alternatively, bags (54), similar to bags 22 but completely buried in sand 14 and extending down into layer (16), arranged between pairs of bags 22 receive the filtrate and conduct it easily to layer 16 (Fig. 6, not shown). The bags are suspended from horizontal cables (25) by ties 27. The bed is cleaned by backwashing from below or by jets of water from pipes (46, 50) extending between the bags and moving along the bed (Figs. 4, 5, not shown) to agitate the sand, the water and solids overflowing into discharge channels (48). Medium 14 may be sand, anthracite, lead or glass powder, the cloth 22 may be polypropylene, polyethylene, metal, natural fibre, P.T.F.E. or polyester and is woven of monofilament strands. Filtration may be under gravity, pressure or vacuum. The enclosing tank may be concrete or metal. The apparatus is used to filter water or to remove solids from a solution of phosphate rock in nitric acid. Fig. 7 illustrates flat hollow filter elements comprising fine sand enclosed between double walls of cloth, supported internally by coarse material and immersed in unfiltered liquid. The lower flaps of the cloth bags are clamped to a support plate by bars 74, and backwash liquid is delivered through valve 82 into the filtrate manifold 78. The claims cover only the Fig. 7 construction.

In a party-line system with provision for revertive calling, a push-button PB at each substation allows the subscriber after dialling to replace the D.C. loop by an A.C. loop through his receiver and condenser QC so that he may hear interrupted ringing tone alternating with an additional audible tone, continuous or interrupted, which the revertive call relay set is arranged to apply. Both tones cease when the called party replies, and the button PB is then released to restore the D.C. loop. The system is of the kind described in Specification 542,039 in which two switches F, C at each substation are stepped alternatively by high voltage impulses from the exchange to connect up the instruments on outgoing and incoming calls.
