Patent GB-941795-A (GB)
Title: Improvements in or relating to permeable bodies
IPC: B22F7/00
Filed: 1962-01-08
Abstract: A method of making permeable articles having fluid conducting passages therein comprises applying a porous powdered metal body to an impervious metal body and heating the bodies to produce bonding at their contacting surfaces, the impervious body being deformed either before or after the bonding operation to form passages between the two bodies. A layer of powdered <PICT:0941795/C3/1> metal 10 is applied to a metal plate 11 which has previously had a pattern of stop-weld applied to the surface, the plate and powder are subjected to a pre-sintering temperature and the metal powder compressed by rolling to the required shape prior to heating to a sintering temperature, which also produces welding of the bodies. The unwelded portions are then distended by fluid inflation or by a mandrel to form passages between the plate and the porous body. The porosity of the powdered metal body may be determined by the choice of particle size, or by including organic particles such as wood flour which combust during the sintering operation. The rolling pressure will also modify the porosity. An apparatus for continuous compressing and sintering comprises a coil of strip 11, a spray gun 19 and masks 20 which cooperate to produce the required pattern of stopweld, a hopper 14 containing powdered metal, a pair of driven rolls 13 and a sintering station 18. In an example a 3/8 inch wide layer of levigated alumina suspended in water was applied to a strip of copper 2 3/4 inches wide and 0.005 inch thick, and a layer of tin solder applied to the remainder of the plate.  A 2 inches wide body, 3/8 inch thick, of sintered copper made from powder with a particle size -100 to +325 Standard U.S. mesh was placed on the plate and the assembly heated to 350  DEG F. to solder the parts together.  In a second example a 1/2 inch wide layer of a graphite suspension was applied to a copper strip .010 inch thick by 1 7/8 inches wide.  The same side of the strip was then coated with a thin layer of copper powder suspended in an organic laquer and the assembly sintered in hydrogen at 1800  DEG F. for 15 minutes.  A second layer of copper powder 1/16 inch thick was then applied, sintered at 1600  DEG F. for 15 minutes in an hydrogen atmosphere and the compound strip then rolled to compact it slightly. The unwelded central strip was expanded by a mandrel. The pre-sintering step may be omitted. Specification 759,804 is referred to.

Title: Improvements to carrier wave communication systems
IPC: H04J1/14
Filed: 1940-01-13
Abstract: 537,966. Carrier telephony. STANDARD TELEPHONES & CABLES, Ltd., and JACOBSEN, B. B. Jan. 13, 1940, No. 783. [Class 40 (iv)] In a system in which the communication currents are held at or below a given level, signalling currents are sent at a definite higher level for actuating a receiver which does not respond to currents of a lower level. The high-level signal may be merely a prefix, actual signalling currents being transmitted subsequently at a lower level. As shown, telephone currents from lines such as A1 are limited in level as at L and passed to a preferably balanced modulator 7, and modulated carrier currents are de-modulated as at DA and passed to a line such as B1. The transmitter S for auxiliary signals may be arranged to send at a level 3 or 4 db. above the maximum level permitted to the speech currents by apparatus L. Alternatively, the apparatus S may send only a prefix at this level, the effect of this prefix being to remove a loss pad at y to make the receiver more sensitive. At the termination of the prefix a loss-pad is inserted at x to reduce the level of the auxiliary signals and the speech line A1 is cut at q to prevent interference by speech currents. The speech line at the receiving end may be cut at r. Alternatively, the receiver may be connected as part of network N2 to make it inoperable by speech from B1. Signals received at R may be sent back to the sender for checking purposes. The signal impulses may also control the transmission equivalent of the channel concerned.
