Title: Improvements in or relating to the making or repairing of roads
IPC: E01C7/06
Filed: 1931-06-20
Abstract: 385,329. Roads ; surface-heating apparatus. KOMLOS, D., 21, Szinyei Merse, Budapest. June 20, 1931, No. 17918. Drawings to Specification. [Class 107.] A method of making or repairing roads comprises forming on or applying to a road bed or foundation an interstitial layer of alkalicontaining rock, such as felspar or like silicates, subjecting the layer to the action of heat by means of a furnace until melting and coagulating of the layer to the desired depth is effected, and then cooling, or allowing to cool, the fused layer. The term "alkali-containing rock" includes both rocks which naturally contain alkali and silica and also rocks in which one of these elements is naturally absent but to which has been added the necessary amount of alkali or silica or both. Suitable materials for the layer are felspar, granite, andesite, diabase or dolorite. When andesite is used for the layer, a temperature of 1350-1400‹ C. is necessary for four hours in order to melt the layer to a depth of 5 cms. The furnace may be left in position to protect the melted layer until the latter is quite cool, and if desired cooling may be accelerated by connecting the combustion chamber of the furnace to an exhauster. When the surface of the road consists of a material of a soil-like nature, holes are drilled into the soil and a layer of felspar applied. When the materials constituting the interstitial layer contain too high a content of alkali, a siliceous substance such as surface soil of a sandy nature, sand, quartz, sandstone, or finely-ground fireclay may be added to increase the viscosity of the melt. This addition may be effected by sprinkling the siliceous substance on the interstitial layer or by blowing the substance thereon during melting. If the application of this substance is continued after melting is completed but while the layer is still soft, a rough surface is produced on the road. Where the surface on which the road is to be prepared or repaired consists mainly of igneous rocky material, such as macadam, the layer to be fused is formed by loosening the earth or road to a depth of 8 to 10 centimetres. If the surface consists of a loamy, sandy, gravelly or soil-like material, the layer is formed by loosening the earth and adding a quantity of broken alkali-containing rock such as felspar. The furnace may consist of a rectangular body, which is closed on all sides except at the base and contains one or more burners. Spaces between adjacent sections of a road constructed as described above, or cracks or fissures formed in such a road, are adapted to be filled with a material such as surface soil, sand, quartz, sandstone or fireclay mixed with a binder such as lead oxide, and heat is applied thereto. The binder may consist alternatively of linseed oil and lead oxide.

Abstract: 1,066,813. Bowling alleys. AMERICAN MACHINE & FOUNDRY CO. May 4, 1964 [May 13, 1963], No. 18428/64. Heading A6D. A bowling alley installation comprises a pit conveyor 4 for receiving spent pins and balls from the playing deck A, the conveyor delivering pins to an elevator (not shown) at the rear of the pit, and diverting the balls to an exit aperture 12 in the kickback k of the alley, from whence the balls are lifted by device 40 on to return tracks R, the device 40 and tracks R being mounted exteriorly of the kickback. Balls issuing from the exit aperture are fed to the lifting device by means of a driven, resiliently mounted roller 118 having a friction surface, and co operating with a guide surface 114. The balls are then rolled up the sloping portion 68 of the return track (which comprises parallel rods preferably sheathed in rubber tubing), by a driven, endless belt 42 mounted on a framework F which includes a spring 62 to maintain the correct tension in the belt and is mounted on pivoted links 70, 72 so as to be movable away from the track 68 as the ball climbs the latter. This ensures that whilst a ball is on the track 68, the lower part of the belt 42 is spaced from the track by a distance which is greater than the diameter of a ball, so that two balls will not be on the track simultaneously. A paddle 200 is mounted exteriorily of the kickback for reciprocation towards and away from the exit hole 12 to redirect any pins issuing from the hole back in to the alley pit, the drive to the paddle including a yieldable operating member such as a dashpot 220 whereby the pressure exerted by a ball on the paddle is sufficient to cause the operating member to yield and arrest operation of the paddle to allow the ball to pass through the hole 12 to the foot of the lifting device 40. Preferably the ball lifting device 40 is installed between the kickbacks of two adjacent alleys and is arranged to serve both.

Patent GB-381539-A (GB)
Title: High-frequency thermionic amplifier
IPC: H03G5/00
Filed: 1931-06-25
Abstract: 381,539. Valve amplifying circuits. HAZELTINE CORPORATION, 15, Exchange Place, Jersey City, New Jersey, U.S.A.-(Assignees of Macdonald, W. A. ; Little Neck, New York, U.S.A.) June 25, 1931, No. 18441. Convention date, July 21, 1930.. [Classes 40. (iii) and 40 (v).] The invention relates to couplings for multistage wireless receivers adapted for ganged control of tuning and to maintain a constant band-width and constant amplification throughout the tuning range. The input coupling A comprises a large primary inductance P1 so that the aerial is resonant at a slightly lower frequency than the lowest frequency to be received. The response with frequency may be controlled further by arranging a capacitive coupling B1 to aid or oppose the magnetic coupling. The tunable circuits C1, S1, C2, S2 have a mixed coupling to maintain a constant band-width while inductance P2 compensates for the loss of inductance in coil S1 due to the proximity of the aerial inductance P1 and thus facilitates ganging. The coupling B is aperiodic due to resistance R3 or to the winding of the coils with resistance wire and provides a small step up. Volume is controlled by ganged resistances R1, R4, which being associated with untuned circuits do not affect ganging of the tuning condensers. Coupling C comprises a transformer T4 having a primary P1 resonant at a frequency slightly lower than the lowest operating frequency in series with a small inductive primary P2. The overall response curve and band-width are further modified by the impedance K4, R5 in the secondary circuit and the inherent capacitive coupling B2. Since the overall band-width is maintained substantially constant the sidebands may be cut and a constant correcting circuit comprising resistance condenser combination K9, R9 be used. A low pass filter section L1, K8 is provided to remove high-frequency currents from the output circuit of the detector V5. The anode and screen-grid circuits of the valves V1 .. V4 are decoupled by resistances 8, 9 and shunt condensers 12 while grid bias is obtained from voltage dropping resistance 11, which tends to stabilize operation by counteracting variations in valve mutual conductance. The detector bias is obtained from voltage dropping resistance 13 which minimizes to a considerable degree detector overloading. In a modification, Fig. 2 (not shown), couplings of the type A are provided with resistance capacity coupling impedances in addition to the magnetic and capacitive couplings between the two tuned circuits and the second volume control may be a variable resistance across the primary circuit of a tunable intervalve coupling. In addition band-width and selectivity may be controlled by using magnetic or capacitive coupling alone and by employing a single primary resonant at a frequency lower than the lowest operating frequency or by using a single primary of a relative few turns in combination with a capacitive coupling.

Abstract: 935,347. Applying pre-determined tension to bolts. G.K.N. GROUP SERVICES Ltd. May 18, 1961 [May 26, 1960], No. 18598/60. Class 89 (1). In a bolted connection one of the connection elements has separate projections extending from a face thereof lying in a plane normal to the bolt axis and spaced around it, and engaging with an abutment surface in the connection, also in a plane normal to the bolt axis, to provide, between the said element face and the abutment surface a visible gap or gaps, the projection form being such that when the element is loaded by tension induced in the bolt shank during tightening of the connection, element portions adjacent the projections will yield plastically so that the dimensions of the gap or gaps are diminished. Preferably, projection form is such that the majority of the plastic yield occurs at substantially uniform load and hence the major part of the diminishing in gap size to nothing. With a bolt 10 (Figs. 1 and 2 (Prov. Specification), the underside of the head 14 is recessed at 13 to provide projections 14 and has grooves 17. The cross-section is reduced in thickness at 17. A nut, which may be square in shape, may be similarly formed around the hole therein. A hexagonal nut (Fig. 5), has a recessed portion 31, grooves 32, and feet 33. The said connection element may be a washer. A sealing washer or sealing compound may be used under the head of a bolt or nut. If this is required to avoid corrosion the thickness of the washer or compound is chosen to be at least equal to the dimension of the gap corresponding to the minimum tension to be in the bolt shank, and compressed on tightening to give the seal. A load-indicating washer (Fig. 6), having a plain central hole, may be a ring 40 (Figs. 6 and 7), fitted in the portion 13 (Fig. 1), having brightlycoloured tabs 41 locating in the gaps 15, and projecting out therefrom when the ring 40 is flattened with closure of the gaps.
