[Class 68 (ii).] A method of making a concrete pile in situ in a preparatory tube consists in ramming the tube by means of a main hammer striking the top of the tube while a tamping-hammer remains suspended in the tube, introducing small quantities of concrete and tamping them while the tube is extracted in stages. A tube A with a loose end B is driven by a drop hammer F and a tamping hammer K which always remains in the tube A is operated by means of a rope P passing through the hammer F, anvil C, and dolly E. Concrete is fed through a spout D on the upper end of the tube A. The tube is lifted by ropes H, and the concrete tamped spreads to form a " bulb " above the shoe B and round the reinforcement R. A second and other " bulbs " may be similarly formed as the tube A is withdrawn. A steam &c. hammer for use in this process comprises a hollow piston-rod down which the rope P is passed.

Abstract: 923,209. Electro-osmotic integrators. UNION CARBIDE CORPORATION. April 14, 1961 [April 22, 1960], No. 13434/61. Class 37. Relates to an electro-osmotic integrator wherein there is included a vessel 10 made of glass or plastic containing a polar liquid, a porous disc 12 dividing the vessel into two compartments, a pair of electrodes 14, 16 close to the disc, one in each compartment and a capillary 24 communicating with both compartments calibrated to give an indication of the time integral of the voltage applied between the electrodes. The porous disc 12 is composed of " fritted " (partly fused) glass of pore size 0.01-1 micron; while preferred polar liquids are water or acetone containing a trace of silver chloride. Methanol, ethanol, acetonitrile and propionitrile are also mentioned. The electrodes used may be porous silver; other electrode materials mentioned are thallium, copper, cadmium and lead. In operation the electrodes of the device are connected to a voltage source and this causes movement of the liquid through the disc 12 by electro-osmosis. If the voltage is interrupted the position of liquid in the capillary 22 will remain relatively unchanged provided the pore sizes in the disc are sufficiently small. Thus if a suitable shunt resistance is connected across the leads 18, 20, the device when properly calibrated can be used to integrate the passage of current with respect to time in a circuit. In Fig. 2 the device is shown used as a state of charge indicator for a battery B.

Abstract: 560,539. Gauges. SOLEX, Ltd., and WATTEBOT, L. E. Sept. 24, 1942, No. 13442. [Class 106 (ii)] Gauging apparatus of the type in which the rate of escape of a fluid, such as compressed air, through a nozzle structure is used for measuring linear dimensions, is characterised in that the actual nozzle structure comprises at least one nozzle contacting a surface being operated upon, in conjunction with at least one measuring nozzle, the gauging fluid being supplied to all the nozzles from a single conduit or branched conduits. In Fig. 1, the test-piece 10 is inserted in the gauge body and is contacted by a contact nozzle 14 in a nozzle structure 13 slidable in the body, the measuring nozzle 15 being spring-pressed to open to an extent controlled by the dimensions of the test-piece. The loss of pressure, indicated on a manometer, indicates the dimension required. In Fig. 2, the internal diameter of a member 32 is determined by a gauge having two contact nozzles 24, 25 and a measuring nozzle 27 supplied by a branched conduit 30. In Fig. 5, two nozzle structures 60, 61 are aligned, with the measuring nozzles adjacent and pressed apart by a spring 62. Fluid is supplied to the structure 60 which feeds the structure 61.

Abstract: 135,291. Percival, S., (Lyons, H. C.). Nov. 20, 1918. Moving-chamber apparatus.- Relates to apparatus of the dipping type employing a tilting bucket, applicable specially to milk churns. The churn is provided with a detachable hood having a lateral delivery port, and the movement of the dipper is such that, when raised, its spout projects from the port clear of the hood. In the form shown in Figs. 1 and 2, the hoods H, fitting in the neck c of the churn, has an opening h<1> which is normally closed by a sliding door h<2> having a tripping-flange h<x>. The dipper D, which is pivoted at d<3> to a rod M passing through a guide h<4> in the hood, has a spout d, the rear end d<x> of which normally rests against the rod M. When the dipper is raised, the spout comes into contact with the flange h<x> and lifts the door h<2> until arrested by the flanged top of the hood, further movement of the rod M causing the dipper to be tilted with its spout projecting through the opening h<1> and delivering its contents through the hole d<4> into a receptacle R.

A door hinge which is adjustable in three dimensions comprises two hingeably connected plate elements, one carrying a ball mounted on a threaded rod or tube so as to be adjustable in one dimension relative to its associated plate element, and the other carrying a socket engaging the ball and mounted so as to be adjustable in any direction perpendicular to the adjustment dimension of the ball. The plate portion 1b of the element 1 has a tapped hole 3 carrying a screw-threaded rod 4 having at one end a part-spherical head (i.e. the ball 6) and at the other end a hexagonal cross-sectioned recess 7 for rotating the rod, or holding it when clamping the lock nut 8. The portion 2b has a bore 9 carrying a pin 11, with a clearance j, the pin having an enlarged head 12 with a recess 16 and a shoulder 13 which bears on the face 14 of 2b. The recess encloses a socket element 17 formed from plastic or sintered metal having a low frictional coefficient, receiving the ball, the latter has a peripheral extent greater than 180‹ (i.e. more than a hemisphere), and is retained in the socket by a collar 15 screwed on to the head comprising the socket. The other end of the pin 11 is screw-threaded and is clamped in the bore 9 by tightening a nut 18 with a lock washer 19 carried on the thread 21, thus bringing the shoulder 13 of the head 12 to bear on the face 14; the head has two flat faces whereby it may be held when tightening the nut 18. The ball is thus adjustable in a direction up or down along the axis of the hinge, by screwing the threaded rod 4, and the socket is adjustable perpendicular to said axis by movement of the pin 11 within the clearance j. The hinge is particularly useful for mounting automobile doors when the plates 1a and 1b may be welded to the vehicle door A and body B respectively.

Arsenic, copper, and nickel, depositing. - A coating of metal upon metal for electrotyping for printing work, for sound-reproducing records, and for other purposes, is produced electrolytically in three stages. The metal is first coated with a very thin film of arsenic by electro-deposition from a solution prepared from arsenious acid, potassium cyanide, caustic soda, and acetic acid. This coating enables the after-work to be stripped or parted. A thin coating of nickel is then deposited to provide a hard face, and on this copper is then rapidly deposited.
