Abstract: 1391662 Wells &c FUDO KENSETSU CO Ltd 22 June 1972 [18 Sept 1971] 29277/72 Heading E1F In the formation of a compacted sand drain by driving casing into the ground, supplying sand to the casing, partially withdrawing the casing to form a cavity, filling the cavity with sand discharged from the casing, driving the casing to compact the sand, and repeating the operations of supplying sand, partially withdrawing the casing, filling the cavity with sand, and driving the casing to compact the sand until the drain is formed, the volumes of sand discharged into the cavity and/or the bearing strength of the sand after each compaction are or is measured and compared with design valves appropriate the depth to facilitate any necessary adjustment to design valves during subsequent operations. Two indicators are used in the formation of a drain, one giving the actual depth and the depth that the casing has to be driven to give the design volume of sand discharged at the depth, and the second giving the design bearing strength at various depths and the actual bearing strength after driving the casing. The bearing strength of the volume of sand in the drain at any depth is derived from that penetration speed of the casing or by the strain measured in the casing.

Title: Improvements in or relating to vehicle shock absorbers
Inventor: KATZ MAURICE
IPC: F16F9/34
Filed: 1968-06-20
Abstract: 1,235,536. Hydraulic shock absorbers. M. KATZ. 20 June, 1968 [29 June, 1967], No. 29543/68. Heading F2S. In an hydraulic piston-cylinder shock-absorber, flow of fluid from one side of the piston to the other (e.g. but not necessarily through the piston) is controlled by a valve in which a closure member is spring-urged into a position in which it closes two flow paths through the valve. When the piston is at rest both these paths are closed, and when it moves in a given direction fluid pressure opens one of the flow paths if the movement is slight and the other if the movement is substantial. The latter flow path is more restricted than the former. In Fig. 1, the valve element 3 is urged by a spring 4 to close an aperture 6-7 in the piston 1 of the shock-absorber and the drawing shows the fluid flow path # 1  which is opened when movement of the piston in the upward direction causes fluid pressure above it to just move the element 3 downwardly against the spring. Greater movement in the same direction would close part 6 of the aperture and open part 7 to provide a more restricted flow path f 2 ,(Fig. 3, not shown) through the piston. Fig. 4 (not shown) depicts a modification of the Fig. 1 construction in which the spring 4 of Fig. 1 is supplemented by a second spring (8), only one of these springs acting on the valve element during small displacements thereof and the other spring becoming effective on larger displacement. In Fig. 5, there are two valve elements 15, 19 which are themselves flexible and so act as their own return springs. Each valve element opens, on slight displacement, a relatively wide channel 21 or 27 and on greater displacement closes this channel and opens a narrower channel 30 or 29. The two valve elements are effective in respectively opposite directions of piston movement. The drawing shows two of the four possible flow paths through the piston, viz. the flow path f 3  for slight downward movement of the piston and the flow path f 4  for substantial upward movements of the piston.

Title: Improvements in or relating to electrical moisture meters for "flong" or other moisture absorbent materials
IPC: G01N27/04
Filed: 1949-11-18
Abstract: 664,037. Resistance measurements; moisture meters. LONDON EXPRESS NEWSPAPER, Ltd., and ASHTON, C. J. May 11, 1950 [Nov. 18, 1949], No. 29615/49. Class 37. A meter for measuring moisture in fibrous materials such as stereotype flong comprises a casing c, Fig. 3, with a hinged cover-plate s. The casing carries a micro-ammeter m, preferably graduated in percentages of moisture up to a maximum of 60 per cent, and a handle h with a press-button switch b by which the instrument is rendered operative. The cover-plate s is made of insulating material and can be fixed in closed position by screws. In the plate s are holes through which project two contact-plates p having flanges and pressed outwardly by coilsprings m bearing against an insulating plate n spaced from the plate m by sleeves, bolts, and nuts o. On a third plate k supported from the plate n are mounted a high-tension battery HT, low-tension battery LT, and valve EV. On the inner surface of the top wall of the casing c are mounted a resistance d of 2 megohms which can be adjusted only when the cover s is open, a resistance e of 0.25 megohms which is adjusted by an external knob r, and a double-pole switch g operated by a press-button on the opposite side of the handle h. The plates p are connected in series with the battery HT and a resistance 7, Fig. 4, of 500 megohms, so that the resistance between the plates p of the surface against which they are pressed forms with the resistance 7 a potential divider, the junction of these resistances being connected to the grid 2 of the valve EV. The resistances d, e and meter m are connected in the cathode circuit. The filament 5 is heated by the battery LT and the standing anode current is balanced out by a resistance 8 of one megohm. The switch g has two linked arms 3, 4, of which the former short-circuits the plates p when the switch is closed and the latter closes the filament heating circuit for adjustment of the maximum meter reading before making a measurement. For measuring, the switch g is opened and the filament heating circuit is closed by the switch 9 operated by the press-button b. The meter then indicates the water content of the flong against the surface of which the plates pare pressed.

Abstract: 440,513. Arc-rupturing in switches. ELLISON, Ltd., G., and ANDERSON, J., Wellhead Lane Works, Perry Bar, Birming- ham. Oct. 17, 1934, No. 29745. Addition to 345,454. [Class 38 (v)] The invention of the parent Specification is modified by mounting within the apertures in the pile of spaced plates i of non-magnetic material, an insulating tube q having a longitudinal slot r formed in one side of it, through which the arc can escape to the spaces between the plates. The fixed contact b is mounted in the tube q with slight clearance and extends downwards across several of the spaces. The central core has an insulating sleeve m, and insulating sleeves p surround the rods forming the return path for the flux. Insulating rings j separate the plates i from one another and enclose the spaces between them. When the movable contacts f are lowered to open the circuit, the arcs pass through the slots r into the spaces where they aro whirled round by the radial field set up by the coil. If the arc makes a complete rotation, it is deflected by the closed side of the tube and so prevented from joining either contact again. When first formed, one end of the arc can travel up contact b into the upper plates, but an insulating sleeve h prevents movement along the movable contact f.

Title: An improved mineral oil composition
Filed: 1946-10-08
Abstract: Low-pour test mineral oil compositions comprise a major proportion of a waxy mineral oil, e.g. a lubricating oil, a pour-depressing amount of a high molecular weight condensation product of a long-chain aliphatic compound having at least 10 carbon atoms in the molecule with an aromatic hydrocarbon or a hydroxy or amino derivative thereof, and a pour stability promoting amount of a condensation product prepared (see Group IV (b)) by heat-thickening at about 400 DEG  to 750 DEG  F., a compound of the formula R-COX, where R is a member of the class consisting of alkyl and aryl alkyl radicals having at least 10 carbon atoms in an aliphatic chain, e.g. the stearyl radical, and X is a halogen, e.g. chlorine.  The composition may contain about 0.1-2.0 per cent, e.g. 1.0 to 1.25 per cent of a high mol. wt. condensation product of a chlorinated paraffin wax with naphthalene and about 0.01 to 1.5 per cent, e.g. 0.5-0.75 per cent of stearyl chloride heat-thickened at 400 DEG  to 750 DEG  F.  The aromatic compound used in making the alkyl-aromatic condensation product may be diphenyl, benzene, toluene, amyl-benzene, anthracene, phenol, naphthol, cresol, aniline or xylidine.  The long chain aliphatic compound is preferably paraffin wax chlorinated to about 10-20 per cent chlorine content.  Alternatively the chlorinated wax may be dehydrochlorinated to produce corresponding olefines and the latter may be condensed with the aromatic compound.  Alternative long chain aliphatic compounds which may be used are stearic acid, stearyl chloride, octadecyl alcohol, or cetyl alcohol.  The acyl halide used in the preparation of the other condensation product may be prepared from palmitic or behenic acid or mixtures of acids obtained by the oxidation of paraffin wax.  The oil base stocks may be waxy paraffinic or mixed base mineral oils and may have been partially dewaxed.  Their viscosity may lie within the normal range for lubricating oils or may be of much lower viscosity, e.g. hydraulic oils of viscosity as low as 40 s.u.s. at 100 DEG  F. U.S.A. Specifications 1,815,022 and 2,251,550 are referred to.ALSO:Condensation products which may be used as additives in mineral lubricating &c. oils (see Group III) are prepared by heat-thickening at about 400-750 DEG  F. compounds of the formula R-COX, where R is an alkyl or aralkyl radical having at least 10 carbon atoms in an aliphatic chain, and X is a halogen.  In the example stearyl chloride is heated for 3 hours at 580 DEG  C. until the evolution of hydrogen chloride has ceased and the heat-thickened product heated to 600 DEG  F. at 10-20 mm. mercury pressure to remove volatile impurities.  Alternatively, the acyl halide may be prepared from palmitic, behenic or paraffin wax oxidation acids, and after heat thickening, the product may be dissolved in a solvent and washed free from acid prior to heating under reduced pressure.  U.S.A. Specification 2,251,550 is referred to.
