Abstract: 595,819. Electricity supply. G.M. ENGINEERING (ACTON), Ltd., and NEWELL, J. July 11, 1945, No. 17734. [Class 38 (iv)] [Also in Group XXXVI] Installation systems.-An electrical distribution system, in which conducting bus-bars are supported and insulated in a duct, has fused distribution circuits tapped off from it ; the fuses, fittings and out-going terminals being located in the duct, screened from the busbars and accessible through doors in the duct. A dust or trunking 1 has doors 2 at intervals, and contains conducting bus-bars 6, 7, 8, 9 supported by transverse insulating plates 10 mounted on pillars 11, projecting from the back of the duct. Opposite each door, the pillars carry an insulating plate 12, behind which slides a thin insulating screen plate 14, larger than the door aperture and lotted at 15, 16, 17, 18, so that the bus-bars are accessible when the screen plate is slid to the left, as in Fig. 1, but when it is slid to the right, the apertures are obscured behind the insulating plate 12, on which are mounted outgoing terminals 13b, connected to distribution cables passing through the conduit 31 in the floor of the duct. Insulating fuse holders 19, 19a, 19b, carrying tubular fuses 22, 22a, 22b, have at their ends resilient clip contacts of unequal length, the longer being adapted to engage a bus-bar and the shorter, an appropriate outgoing terminal. No fuse being required in the neutral distribution cable, it is connected to a terminal block 30 carrying a clip contact which engages the neutral bus-bar. In a modification (not shown), complete fuse units are mounted on a common base, together with a neutral terminal, each being fitted with a suitable contact clip to engage the appropriate bus-bar. Outgoing cables are connected direct to the fuse units and to the neutral terminal, While the contact clips are strong enough to form the only support for the complete plug-in units. The invention is suitable for 2, 3 or 4 wire systems, and for use as a rising main, for example in blocks of fiats.

Title: Improvements in, or relating to, aerials
IPC: H01Q9/12
Filed: 1955-06-21
Abstract: 793,552. Aerials. CHERRINGTON, G. L. A. June 21, 1956 [June 21, 1955], No. 17853/55. Class 40 (7). An aerial capable of receiving signals in two frequency bands comprises two pairs of tubular elements, 1 and 2, 3 and 4, one of each pair being mounted on and electrically connected to each of two parallel conductors 10 which are secured by but insulated from a support clamp 16 and 17. The elements are closed at their outer ends by plugs 5 and the elements of one pair 1, 2 are longer than those of the other pair. Each element is socketed on to a split spigot 6 formed integrally with a pierced mounting ear 9. Each conductor 10 comprises a bolt having a head 10a against which butts mounting ear 9 for element 3 or 4. The rounded section of this ear (see Fig. 2) fits into a diametric groove in an insulating sleeve 11 fitted on the rod. A second insulating sleeve 12 follows and then the bolt is threaded into the tapped hole in ear 9 for rod 1 or 2 as the case may be. A lock-nut 13 and terminal 15 for securing the feeder completes the assembly. The adjoining portions of insulators 11 and 12 are of reduced diameter and fit in parallel grooves in the faces of clamp-pieces 16 and 17. The clamp is mounted on a bracket 22 which can be attached to any suitable support by screws 23. The domed head of this bracket has a slot 19 in it through which projects a bolt 18 and on to the bolt are secured the clamppieces 16, 17 by wing nut 21. The aerial is thus capable of considerable adjustment; the bolt 18 may be moved angularly round the domed head of the bracket in the slot 19, the clamp may be rotated on the bolt 18 and the elements may be rotated individually about the axis of conductors 10. It is preferred to arrange the rods as a straight dipole to receive the stronger signals and those to receive the other frequency band as a V dipole.

Title: Manufacture of cementitious materials
IPC: C04B7/00
Filed: 1933-06-22
Abstract: A process for producing a cement consists in mixing lime and finely divided siliceous or argillaceous materials in the presence of sufficient water to insure hydration of all the quicklime present and to ensure the presence of free water throughout the mixing operation, maintaining the mixture at a controlled elevated temperature from about 100 to 400 DEG  C. sufficient to produce reactions between the lime and the silica, and while continuing to provide a limited quantity of water continuing the mixing under the controlled temperature conditions until a product having hydraulic properties is produced.  The time taken may vary from a few minutes to an hour or more according to the temperatures employed and the fineness of grinding of the raw materials.  The lime may be quicklime, hydrated lime or air-slaked lime, and the non-calcareous component may be silica sand, siliceous earths, e.g. diatomaceous earth, tripoli, clay and other argillaceous and argillocalcareous material generally known to be suitable as the material for supplying the siliceous and aluminous components in Portland cement manufacture and in which the proportion of siliceous constituents is large compared with aluminous constituents.  The mixing may be accompanied by grinding p throughout the process.  Portland cement or Portland cement clinker may be added during the mixing or mixing and grinding operation, in varying amounts according to the nature of the product desired.  An addition of 10-20 per cent, by weight of the mixture, results in a satisfactory masonry or stuccoing cement, a mixture containing 65 per cent of Portland cement is comparable to a high grade Portland cement, and one containing 70-90 per cent has the characteristics of a super cement.  Accelerating agents may be added, e.g. sodium chloride, calcium chloride, sodium hydroxide and tannic acid, and also waterproofing-agents, e.g. rosin.  Specifications 361,901 and 385,698 are referred to.

Filed: 1951-07-31
Abstract: 720,278. Diamond tools. WHEEL TRUEING TOOL CO. July 31, 1951, No. 18091/51. Class 124. A drill bit or like tool comprises a coherent sintered body portion including a inner layer of tungsten and diamonds embedded in and exposed at the surface of an outer layer of tungstentungsten carbide, the diamonds being surrounded by a layer of massive tungsten carbide. In the form shown, there is placed in a carbon mould 10 a number of diamonds or discrete diamond particles 13 kept in upright position by a setting matrix 14, a layer 15 of a mixture of powdered tungsten and tungsten carbide, and then a layer 16 of tungsten particles, these layers then being cold compacted under a pressure of 400-600 p.s.i. The diamonds may be set in a single horizontal plane or in a set of inclined planes or steps. The tungsten powder is of less than 200 mesh and the tungsten carbide varies between 30 and 200 mesh. German silver, bronze or other brazing metal 21 is then added, and the compact heated for at least 1 hour at a temperature of 1700-2100‹F. but below the melting point of the brazing metal. This forms massive tungsten carbide in the layer 18 including the diamonds by interaction of the tungsten-tungsten carbide mixture and the carbon of the mould, a layer of tungsten carbide at the junction of the tungsten and the carbon wall of the mould, and a relatively soft solid tungsten inner mass 19. Further heating to above 2100‹F. causes the brazing metal to infiltrate the compact. The resulting mass is then compressed at 400-600 p.s.i. before cooling.

Sphygmographs. -- A sphygmograph comprises a casing 6, Fig. 2, containing two gauge capsules or Bourdon tubes 7, 8 connected, through tubes 9, 18 respectively, with the atmosphere at 10 and with a valve 19. The tube 7 is connected by a link 11 with a forked member 13, pivoted at 12 and carrying a cord 14 wound round the spindle 15 of the recording table (not shown). The tube 8 is connected by a link 20 with a spindle 21 carrying the recording pen 22. The tube 8 is also angularly adjustable by a screw at 17. The valve 19, Figs. 2 and 4, has connections 23, 24, 25 to the tube 18, an artery-constricting pneumatic cuff and a small air pump 26 respectively. A rotatable cock 27 having passages 29. 30 in one setting places the interior of the casing 6, the tube 8, and the pneumatic cuff in communication with the air pump 26, and when turned through 90‹, cuts off the air-pump and places the cuff and the tube 8 in communication with the interior of the casing 6 through a capillary passage (not shown) in the cock. In use, air is pumped into the casing 6, the tube 8, and the cuff to a pressure greater than that of the arteries, the recording table being simultaneously rotated by the action of the tube 7. The cock 27 is then turned and a leak 34 in the casing 6 is opened. When the falling pressure, which effects reverse rotation of the recording table, reaches the arterial pressure, pulse beats are recorded by the pen 22 through the agency of the tube 8, the pressure pulses being subsequently dissipated through the capillaxy passage in the cock 27, or through alternative or additional capillary openings in the tubes 8 or 18, some of which may be adjustable in size. The instrument is calibrated by injecting known volumes of air into the tube 8 while the cuff is in position. When out. of use, the pen 22 is held from the recording table by a vertical pin supported on one end of a lever, and is released by the rotation of the cock 27, a cam on which engages the other end of the lever. The casing 6 is provided with a lid, clamped or otherwise attached thereto and provided with a glass window which may be clamped between two rubber washers by a metal ring held down by catches. A cover-plate is provided, beneath the recording table, for the pressure-actuated apparatus. The leak 34 may comprise a resiliently mounted conical valve and a screw-threaded apertured cap 37, rotation of which presses the valve, to any desired extent, from its seating.
