Title: Automatic volume control system
IPC: H03G3/22
Filed: 1940-05-22
Abstract: 542,030. Automatic volume control. PHILCO RADIO & TELEVISION CORPORATION. May 22, 1940, No. 9077. Convention date, June 17, 1939. [Class 40 (v)] A degenerative plate rectifier is arranged so that negative A.V.C. potential may be taken direct from the anode. As shown in Fig. 1, the output from the signal transfer means 2, for example an intermediate frequency amplifier, is applied to a pentode 3 arranged as a degenerator plate rectifier. The detected output is taken across a cathode load resistance 4 having a byepass condenser 5, The anode is connected to earth through a resistance 7, anode circuit power being supplied by a source 6. Thus the anode is always negative with respect to earth and is increasingly negative with an increased signal. This gives a suitable negative A.V.C. voltage which is applied from the anode of pentode 3 to the grids of the valves in the earlier stages, after smoothing by resistance 8 and condenser 9. Since the total cathode current is substantially independent of the plate potential this arrangement does not affect the detection. Modifications are described in which delay is introduced by a suitably biased diode connected across impedance 7 (Figs. 2 and 3, not shown). Specification 540,454 is referred to.

Abstract: 1514016 Ligaturing apparatus P PERISSE 8 March 1976 [14 March 1975] 09198/76 Heading A5R Surgical ligaturing apparatus comprises an elongate body 1 with a pair of actuating cams 2, 3 with finger rings, a tubular charger 5 being located in a longitudinal slide and containing ligature carrying cartridges 8 formed in a train and threaded onto a tubular shaft 6 co-axial with the body and formed at its rearward end with a connection for a flexible conduit attached to a vacuum source so that a suction force will be created at its front end to suck in a bud-shaped portion of tissue provided with a blood vessel to be ligatured. The cartridges each have a tubular front end 10 co-axial with shaft 6 to form an annular space 11 for a ligature 12 Fig. 4. The ligature has two turns 13, 14 two hitches 15, 16 and has its ends 18, 19 extending past guides 20, 21, knives 26, 27 abutments 25 on the front end of the charger, to anchorages 24. A resilient rearwardly extending arm 32 engages a recess 31 in the following cartridge and a heel 45 of the leading cartridge engages in recesses 44 at the front bifurcated end of a member 40 slidable in a groove at the bottom of the slide and actuated by the arms 2, 3. In operation of the apparatus the arm 2 is moved inwards against spring 49 and via linkage 51, 52, 53 moves member 40 forwards so as to move the leading cartridge via heel 45 and recesses 44 by an amount d 1 . Movement of this cartridge causes ramps 33, 35 on the arm 32 to ride up surfaces 35, 36 whereby the arm is disconnected from the following cartridge. Simultaneously the ends of the knot pull against abutments 25 to tighten the ligature around tissue in shaft 6. Further inward movement of arm 2 causes the linkage 51, 52, 53 to go over-centre and return the leading cartridge by an amount d 2 . This will cause the following cartridge to move the knives 26, 27 forwards in the leading cartridge to cut the ends of the ligature, the following cartridge having been engaged with a pawl 60 during the initial forward movement of the leading cartridge. The arm 2 is prevented from returning to its initial position by its rearward end engaging a spring loaded pivoted pawl 57. Inwards movement of arm 3 against spring 50 now causes member 40 to move the leading cartridge forwards by an amount d 3  so that it is ejected from the charger, this movement of arm 3 moving arm 2 so that it is released from pawl 57. Both arms can now return to their initial positions under the action of springs 49, 50 and the following cartridge takes up the leading position as member 40 is withdrawn and heel 45 of this cartridge is engaged in recesses 44.

The resultant oppositely-phased I.F. signals are applied to opposite ends of a #-type filter section producing a 180 degree phase-shift so that the two signals combine in phase at the input to the first I.F. amplifier 9. Chokes CH1, CH2 are connected as shown to provide a D.C. return path for the rectifier circuits. A condenser 10 (and also if desired a shunt resistance) may be provided to balance the input impedance of the valve 9. A neutralizing condenser 11 may also be provided. In an alternative arrangement, Fig. 4 (not shown), the phase-shifting network is replaced by two 90 degrees phase-shifting #-sections connected in series. Fig. 3 shows a further arrangement in which the phase-shifting network comprises a length of transmission line. The output from the transmission line is coupled to the I.F. amplifier through an impedance transformer CR comprising a length of short-circuited transmission line as shown.

Title: Improvements relating to processes for the bonding of molten aluminium and aluminium alloys to cast iron and steel
Inventor: HALLETT MICHAEL MOUNTJOY
IPC: C23C6/00
Filed: 1951-04-20
Abstract: In a method of bonding molten aluminium and aluminium alloys to cast iron and steel, the surface of the base metal is first mechanically cleaned, if necessary and coated with a flux, then immersed in a zinc bath at a temperature of 450 DEG -700 DEG C. for not less than one minute or more than sixty minutes and finally the aluminium or aluminium alloy is cast thereon at a temperature of 650 DEG -850 DEG C.  Zinc chloride is a suitable flux but others may be used, for example 70 per cent. calcium chloride, 25 per cent. sodium chloride and 5 per cent. potassium chloride.  In an example, grey cast iron was machined, treated with a saturated solution of zinc chloride containing 5 per cent. by volume of concentrated hydrochloric acid, dipped in a bath of electrolytic zinc for one minute at 660 DEG C. transferred to a mould and pure aluminium poured around it at 750 DEG C.  In modifications the zinc bath was at 555 DEG C. or 520 DEG C. and the aluminium was poured at 760 DEG C. or 800 DEG C. respectively.  In another modification the zinc bath was at 625 DEG C. and an aluminium alloy containing 13 per cent. zinc and 3 per cent. copper was cast at 780 DEG C.  Alternatively the zinc bath treatment may be for three minutes at 580 DEG C. and an aluminium silicon alloy cast on at 700 DEG C.  In another example cast p  iron was de-greased, pickled in sulphuric acid inhibited with stannine for 30 seconds at 85 DEG C., washed, immersed for 15 minutes in equal parts of sodium nitrate and potassium nitrate at 400 DEG C. washed again, pickled in hydrofluoric acid for one minute, fluxed with zinc chloride and immersed in a zinc bath for six minutes at 670 DEG C. An aluminium silicon alloy was then cast on it at 620 DEG C.
