Title: Improvements in or relating to volume reduction in the measurement of gases flowing in pipe lines
IPC: G01F1/12
Filed: 1958-02-07
Abstract: 832,871. Integrating-apparatus. GEHRE, H. Feb. 7, 1958 [Feb. 8, 1957], No. 4100/58. Class 106 (4), Apparatus for measuring the volume, as reduced to standard temperature and pressure, of a gas flowing in a pipe line A comprises a continuously variable drive 40, 33 in the transmission from a gas meter 52 to a counter 48 set by a mechanical computer deriving a correction factor Z from the temperature and pressure of the gas in accordance with the gas equation of state. The computor comprises a balance beam 1 which is coupled to an inclination balance 4. The beam is acted on by a manometer 8 connected to the service duct A of the meter 52 and by a barometer 9 sensitive to atmospheric pressure and has an adjustable abutment 16 for co-operation with a pin 17. The pin 17 runs in a vertical guide 18 and is caused to feel for the beam 1 by a detector lever 11 pivoted on a pin 10. The pin 10 is carried by a carriage 21 moved on a horizontal guide 22 by a temperature sensitive apparatus 23, 24, 24<SP>1</SP>. The carriage 21 also carries an horizontally adjustable vertical guide 25 for another pin 27 carried by the lever 11. Once the guide 25 has been adjusted, its distance from the pivot-pin 10 is fixed so that any vertical displacement of the pin 27 is proportional to the ratio of the pressure, causing the vertical displacement of the pin 17, to the temperature, causing the horizontal displacement of the pin 10. The displacement of the pin 27 is used to set the friction wheel 33 relative to the cone 40, so that the counter 48 registers the required volume. A constant speed drive 15, independent of the meter 52, rotates a crank-shaft 13 to actuate the feeler pin 17 periodically with an amplitude to cover the expected variation of the correction factor Z. A brake 61 is provided to prevent pin 17 affecting the positioning of the beam 1 and cam teeth on a disc on the shaft 13 release the brake 61 several times while the cam 14 holds the pin 17 in raised position, thus allowing the beam 1 to follow variations in pressure and temperature. Another brake 69, 71 holds the lever 30, 31, which controls the position of the wheel 33, and releases it to follow up the pin 27 when a cam 63 raises a rod 64 during the sensing part of the cycle. The weight 6<SP>1</SP> is chosen so that the weight 6 is displaced either side of the bottom dead-centre by an angle small enough to introduce only a negligible sine error with the correction factor Z in the region of a fifth to a half its maximum likely value. Specification 742,648 is referred, to.

Title: Improvements in and relating to devices for securing wall boards and the like to beams or the like parts of a building structure
IPC: E04B9/24
Filed: 1947-02-13
Abstract: 622,156. Securing wall boards &c. ANDERSON & SON, Ltd., C. F., and DUNKERLEY, V. Feb. 13, 1947, No. 4146. [Class 20(iv)] A T, L, I or like section beam &c. has a web 3 with slots or apertures 4 and a flange 1, 2 which supports the edge portion of a wall, etc., board a, the board being secured by a wedge device formed of bent strip metal with a base 8, 9 engaging the upper face of the board and a sloping surface 5 extending into a slot in the beam with the edge 4a of the slot engaging a transverse corrugation or projection b on the sloping surface to hold the wedge in position and flex the sloping surface whereby the board is pressed against the flange. The portions 8, 9 may extend inwardly to approximately the centre and be upturned at the ends or the portion 10 at the thin end may be pressed against the sloping side 5a, and these portions may be barbed to dig into the boards and prevent movement. The corrugations may be replaced by projecting tongues, teeth, or burrs. The wedges may be used with boards of different thickness and apertures 4 of varying size.

Title: Improvements in apparatus for annealing metals
IPC: C21D1/74
Filed: 1931-02-11
Abstract: 371,080. Metal heating furnaces. DODERER, W. H., Neudek, near Karlsbad, Czecho-Slovakia. Feb. 11, 1931, No. 4207. [Class 51 (ii).] Charges, conveying; . cooling.-Relates to annealing-furnaces of the kind comprising a heating-muffle 2 with a cooling- extension 12, to which a protective gas is admitted by a connection 13, the gas flowing in opposite directions and escaping at the ends of the muffle and its extension, and comprises (a) the provision of baffles 16, 16a, Fig. 1, for retarding the flow of gas along the extension 12, and (b) the use of a door 23, Fig. 2a, for shutting off the muffle from the cooling-extension while a scavenging-gas is being passed through the latter. The baffles 16, 16a consist of pairs of hinged plates or brushes which yield in the direction of travel of the material under treatment. The muffle is heated by gas and air supplied through ports 6 .. 9, and the products pass to a recuperator through the flues 10, 11. The discharge end of the cooling-extension is inclined and the protective gas escapes through the uptake 15, the arrangement being such that, when a lighter gas than air is used, the gas will not pass below the level of the line GS. In the construction shown in Figs. 2 and 2a the material is passed through the muffle by pairs of overlapping wheels 22, the last two pairs of-which are driven faster than the remainder, so that the material will pass quickly from the muffle to the cooling-extension. In the latter the material is conveyed by rollers 26 mounted on watercooled copper pipes, and these rollers are driven in groups by motors M through worm gearing S and chains 34. The inclination of the muffle increases from the inlet end, and the final portion of the cooling extension is so steep that the materials will descend by gravity. The cooling extension is water-jacketed and the removable cover 28 is made gastight by a seal 29.

A scale 11 mounted on a plate 10 is movable relative to a cursor 12 upon which are engraved three or more concurrent straight index lines 14, 15, 16, the cursor also being movable relative to the scale in a second direction not parallel to the first. In the form shown for calculating viscosity/temperature properties of a lubricating oil, the viscosity scale is engraved upon the plate 11 and the index lines on the cursor correspond to three different temperatures, 210‹ F., 140‹ F., 100‹ F. To calculate the viscosity at 140‹ F. corresponding to 5À05 cs. at 210‹ F. and 22 cs. at 100‹ F., the plate 11 is moved until the line 14 cuts the scale segment 13c at the 5À05 cs. graduation. The cursor 12 is then moved until the index line 16 cuts the scale segment 13c at the 22 cs. graduation when the viscosity at 140‹ F. may be obtained by reading the intersection of the scale segment 13c and the index line 15.

IPC: H04B7/10
Filed: 1929-02-13
Abstract: 306,538. Telefunken Ges. fiir Drahtlose Telegraphie. Feb. 24, 1928, [Convention date]. Fading, preventing. - For the prevention of fading in wireless reception, particularly on short waves, two or more aerials or aerial systems A1, A2, Fig. 1, oriented at right-angles to one another and separated by at least three wave lengths, are arranged to feed directly or indirectly, as by lines K1, K2, into a combined receiving circuit E. The different orientation of the aerials reduces fading effects due to changes in polarization of the arriving waves, whilst the spacial separation reduces the effects due to interference. The aerial systems may be arranged in a straight line, preferably athwart the direction of the arriving waves, or at the corners of a triangle or other geometrical figure. Amplifiers, phase regulators, &c. can be employed in the receiving circuit E, and the combination may be effected before or after rectification. In Fig. 2, each aerial system comprises a vertical aerial A1, A2 and a horizontal aerial R1, R2, shown as a frame aerial. The aerials A1, A2 are connected by lines K1, E2 to a combining circuit H1, and the aerials R1, R2 by lines L1, L2 to a circuit H2. High-frequency currents from HI and H2 are fed to rectifiers G1, G2 which have their output circuits connected to a common indicator or receiver J. In another arrangement (Fig 3, not shown), four straight aerials are spaced apart at the corners of a rectangle, diagonally opposite aerials being parallel to each other and at right-angles to the other pair. They all feed a common receiver.
