Title: True air speed indicator
IPC: G01P5/14
Filed: 1939-01-18
Abstract: 523,974. Differential-pressure gauges. SCHWIEN, L. N. Jan. 18, 1939, No. 1725. Convention date, Jan. 26, 1938. [Class 106 (ii)] In an air speed indicator comprising a member responsive to the difference between static and velocity air pressure and connected by a transmission gear to an indicator, separate static pressure and temperature responsive elements are connected to the transmission gear in such a manner as to vary its multiplying ratio and cause the reading of the indicator to be compensated for changing pressure and temperature. A bellows 46 receives internally velocity air pressure through pipe 44 and the static air pressure line is connected to the casing 10 of the instrument. The movement of bellows 46 is thus proportional to the difference between these pressures and the speed indicator band 23 is operated therefrom by a post 60 and a bell crank lever 65 acting on a lever 66 operating a toothed sector geared to the shaft of pointer 23. An evacuated bellows 95 is provided in the casing which thus moves according to the static pressure, and through levers and linkage 127 moves the post 60 to alter the effective length of lever 65. A further bellows 152 is connected to a thermal element containing expansible fluid and through links 186 and 200 shifts lever 65 longitudinally on its axis. The effective length of lever 66 is thus altered. Thus the multiplying ratio of the transmission is altered to compensate for both pressure and temperature changes. The bellows 152 also actuates a temperature indicating hand 24 through a linkage 205.

Title: Improvements relating to tolerance limit gauges
IPC: G01B5/08
Filed: 1952-01-22
Abstract: 698,308. Linear-dimension gauges. AKTIEBOLAGET SVENSKA KULLAGERFABRIKEN. Jan. 22, 1952 [Jan. 26, 1951], No. 1794/62. Class 106 (ii). A plug gauge is provided with fixed gauging surfaces for gauging the tolerance limit of a body on the go side and a separate gauging surface for gauging the tolerance limit on the not-go side, said separate gauging surface being resiliently movable during a gauging operation and the whole gauge being so arranged that the go and not-go surfaces can be brought selectively into a gauging position by tilting the gauge body. Fig. 1 shows a plug gauge 1 on an arm 2, the opposed ends 4 and 5 of the gauge body 1 forming the " go " surfaces of the gauge. The " not-go " surfaces comprise the end 5 and the outer tip 10 of a finger 8, Fig. 3, slidable inwardly within the end 4 against resilient means such as a rubber pad 11. Figs. 4 and 5 illustrate how the gauge is used to test a bore 16 assumed to be within the prescribed limits. The gauge is inserted in the bore in an oblique position as shown in Fig. 4 so that it can be freely moved to the position to be gauged. The handle 2 is then allowed to move downwardly. If the gauge tilts without resistance, the bore is too large. When the bore is within the prescribed limits, the tip 10 of the finger 8 engages the wall 16 of the bore as the gauge is tilted, this engagement being plainly felt by the operator and the gauge can be tilted entirely past its central position shown in dotted lines in Fig. 5 to the position shown in full lines. Within such limits the pressure from the wall of the bore forces the finger 8 backwards in its groove, compressing the rubber pad 11 sufficiently to permit the finger 8 to pass the central position. If the gauge body cannot be tilted entirely over to the final position shown by full lines in Fig. 5, then the hole is too small. According to a modification the finger 8 may be replaced by a member hinged to the gauge body. Specification 608,171 is referred to.

IPC: B22D27/06
Filed: 1968-01-12
Abstract: 1,217,083. Casting processes; ingot moulds. H. J. DAUSSAN. 12 Jan., 1968 [13 Jan., 1967], No. 1835/68. Heading B3F. To form a covering crust of porous slag D<SP>2</SP> and metal D<SP>1</SP>, Fig. 9, during casting of ingots of rimming, balanced or fully killed steels, a certain amount of solid rim S, Fig. 1, is allowed to form and then a deoxidizer I, Fig. 6, in divided form is spread on the liquid surface to form a shrinkage basin a, b, c, d which is then spread with a mixture II containing an oxidizing agent and a reducing agent which react exothermically at the metal heat to form the crust D<SP>1</SP>, D<SP>2</SP>. There may be a further addition III (for cooling and/or fluxing) of liquid or solid CO 2 , a jet of water, or water in combined form in sodium borate or boric acid, or a solution of sodium silicate or carbonate. Al, Si, Ca or Ti or an alloy or ferroalloy thereof is used as the deoxidizer I or reducing agent in II and the oxidizing agent is iron oxide scale. A frusto-pyramidal taper may be imported to the top of the mould A<SP>2</SP>, Fig. 6, by an integral or fitted body A<SP>3</SP> of the mould metal. For adding the substantances I and II there is used a container B, with an end 4 droppable by means of a cable passing through a hollow handle 3 to a lever at the free end. Alternatively, when a sufficient rim of solid metal has formed, a heat-destructible container B<SP>1</SP>, Fig. 6, including the substances I, II and III is supported by its edge on the rim. The wall of a bottom compartment is mainly consumed (leaving a minor part 15a) to deposit the deoxidizer I. Then the centre portion of a wall of two crossed sheets of corrugated cardboard or a wall of spongy cellulose is burned away to spread the exothermic mixture II in the shrinkage basin thus formed. The wall contains the cooling and/or flux material III at least at the periphery.

Title: Method of Impulse-Arc Welding with a Consumable Electrode
Inventor: POTAPIEVSKY ARKADY GRIGORIEVIC
IPC: B23K9/09
Filed: 1967-01-13
Abstract: 1,164,005. Welding by fusion. INSTITUT ELEKTROSVARKI IMENI E. O. PATONA. 13 Jan., 1967, No. 1958/67. Heading B3R. [Also in Division H2] In consumable electrode arc welding in which D.C. impulses of current Jimp. are superimposed on a D.C. arc current J 1  of the same polarity, the transfer of electrode metal is at the rate of one drop per Jimp. impulse. In the ease of a short circuiting arc the impulses are of current Jimp = (2 to 12) J 1 , duration 1 to 15 millisecs, rate of increase 200 to 5000 KA/sec and frequency 5 to 300/sec. In the case of a continuous arc the impulses are of current Jimp = (6 to 12) J 1 , duration 1 to 3.5 millisecs., rate of increase 700 to 5000 KA/sec. and frequency 25 to 300/ sec. For controlling the thermal cycle and penetration and the melting of the electrode, each impulse may be preceded by one or more auxiliary impulses of current (2 to 5) J 1 , duration 3.5 to 15 millisecs. and rate of increase 30 to 700 KA/sec. To control the arc stability each main impulse may be preceded by one or more auxiliary impulses of current (2 to 10) J 1 , duration 0.1 to 0.9 millisecs. and rate of increase 700 to 7000 KA/sec. Both types of auxiliary impulses may be used together but such impulses do not cause transfer of metal. The main impulses may occur at a preset frequency or may be triggered off by a cyclic change in the arc parameters caused, e.g. by the growth of the droplet on the electrode tip or by shortcircuiting of the arc. Gas shielded arc welding of Cu, Al, Ti, stainless steel and alloys such as Al/Mg may be effected with gases such as CO 2 , A, He. The arc current is supplied by a 3-phase transformer 1, Fig. 6, and rectifier 4 through a variable inductance 5. A transformer 6 in series with the rectifier 4 charges a capacitor 8 during shortcircuiting of the arc. A control device 10 also responds to shortcircuiting of the arc after a delay to cause a valve 9 to conduct and to discharge capacitor 8 through a resistor 12 and inductance 11 to produce the main impulse. In a modification, Fig. 7 (not shown), a second A.C. source is connected through a transformer to charge the capacitor and to control through a phase shifter the valve controlling discharge of the capacitor.
