Title: Improvements in or relating to apparatus for surface hardening metal articles in succession
IPC: C21D1/08
Filed: 1940-11-11
Abstract: 545,256. Surface 'hardening. SHORTER PROCESS CO., Ltd. (Linde Air Products Co.). Nov. 11, 1940, No. 16340. [Class 72] An apparatus for surface hardening a succession of similar articles comprises movable supports for two articles adapted to be moved intermittently between a position in which a first article is heated and a position in which a second article is heated, the first article being quenched during the movement, and the movement of the apparatus is reversed for quenching the second article and bringing a third article into the heating position. As shown, two articles A. A<SP>1</SP> are supported in workholders H, H<SP>1</SP> mounted for rotation on a carriage C. The article A is heated by oxy-acetylene blow pipes B for a pre-determined time after which arms 36, 37 and 38, 39 supporting the holders H, H' are moved downwardly to lower the articles into a tank T of quenching medium and the carriage C is moved to bring the article A<SP>1</SP> below the heating position, the articles being rotated during all the operations. The arms are then raised, the article A<SP>1</SP> being heated and the article A being removed and replaced by a third article. When A' has been heated the arms again drop, the carriage C moves in the opposite direction to bring the third article into a position below the heating means, the arms raised, and the operations repeated. A motor M, operating through ears, moves the carriage, and a motor M' rotates the workpieces and causes the lowering of the arms into the quenching tank, e.g. by the release of a latch. The operations may be manually or automatically controlled. The arms in the lowered position may be held at a pre-determined depth in quenching medium which may be circulated. The speed of rotation of the articles, and the heating time may be adjustable.

Title: Improvements in and relating to soldering fluxes
Inventor: EMBLEM HAROLD GARTON
IPC: B23K35/36
Filed: 1951-07-11
Abstract: A substantially non-acidic flux including or comprising hydrazine phosphate is used in soldering process; alternatively, a soldering flux, which is preferably substantially non-acidic comprises hydrazine phosphate in association with a vehicle for making it adherent to metal, such vehicle including or comprising an organic substance.  Thus, an aqueous hydrazine orthophosphate solution may be used or the flux may comprise glycerol or cetyl pyridinium bromide in aqueous solution, or a cream or paste may be formed with petroleum jelly and emulsifying wax, or colophony resin may be mixed with powdered hydrazine phosphate.
Patent GB-770736-A (GB)
Title: Average flow indicating system
IPC: G01F15/075
Filed: 1955-06-08
Abstract: 770,736. Electric measuring systems. PANELLIT, Inc. June 8, 1955 [June 15, 1954], No. 16477/55. Class 40 (1). [Also in Group XIX] A recording system comprises flow responsive apparatus for finding the average rate of flow of material in a number of different time intervals in units based on a common period comprising computing means responsive both to means for measuring the quantity of material flowing during an interval and to means for measuring the interval. A sensing device in a recording system 12 is fed repeatedly and sequentially from a stepping switch 46 with voltages proportional to the average rate of flow of material through pipes 2, 2<SP>1</SP> . . . taken over the interval elapsed from the beginning of the last of a succession of hourly periods and the averages are printed automatically at the end of each hourly period and at any instant during the period, as desired, by operation of a manual read out switch. To derive the voltage corresponding to the pipe 2 the instantaneous rate of flow is derived from the difference of pressure either side of a restriction 14 by extracting its square root and is fed to an integrator to drive a shaft 16 in accordance with the quantity that has flowed through the pipe 2. The shaft 16 then acts through a clutch 18 linearly to displace the moving contact of a potentiometer in proportion to the quantity that has flowed since the beginning of the hourly period when it was returned to zero potential position by a spring 32 released by a solenoid 30 when briefly energized upon a synchronous motor 24 acting through a cam 26 on contacts 28. The input to the potentiometer 20 is derived from the moving contact of a potentiometer 22 which is linearly displaced by the motor 24 through a clutch 29 so that it taps a voltage inversely proportional to the interval of time since it was set to maximum potential by a spring 28 under control of the same time cam 26. Thus the output of the potentiometer 22 is directly proportional to the quantity and inversely proportional to the time and so represents the average rate of flow since the beginning of the hourly period. If the static pressure in the system is liable to fluctuate compensation may be introduced through a further potentiometer 36 and where averages are derived from a number of pipes 2, 2<SP>1</SP> and the maximum ranges of the corresponding apparatus vary, scale compensating factors are introduced through potentiometers 44, 44<SP>1</SP>. In an alternative embodiment the inverse time factor may be introduced in the sensing device of the recording system, Fig. 4, not shown.

Title: Roasting particles
Inventor: SOMINSKY DAVID SAMUILOVICH
IPC: C22B1/10
Filed: 1963-04-26
Abstract: Inorganic particles are simultaneously roasted and comminuted by collision with one another by introducing them, as a gas-borne suspension, through opposed nozzles into a roasting chamber, withdrawing particles of desired size and recycling the remaining oversize particles. In the apparatus shown in Fig. 2, preheated particles are introduced through opposed nozzles 5 into the roasting chamber 7 in which they are simultaneously roasted and comminuted by collision, particles of below a certain size are withdrawn through a perforated plate 9 together with spent combustion gases and are passed to a cyclone 14 (not shown) for settling, the spent combustion gases being used to preheat the particles in the bunkers 2; oversize particles are removed through apertures 11 and recycled to the nozzles 5.  Reference is made to roasting limestone of size less than 30 mm. to obtain lime with a surface area up to 5000 square cm. per gram. <PICT:1081085/C1/1>
