Title: Improvements in the manufacturing of porous refractory bodies
IPC: B22F7/00
Filed: 1965-04-27
Abstract: A method of manufacturing a porous refractory metal body e.g tungsten, comprises forming a porous metal substrate of coarse porosity, the substrate having a surface of the required profile and being thicker than the required thickness of the body, impregnating the substrate with emissive material for electron emission e.g. barium calcium aluminate, sintering to the surface a fine porous metal layer and then machining the body.  In an example 1-10 micron tungsten powder is pressed and then sintered at 2200 DEG C. in vacuo or a reducing atmosphere to a porosity of 25%. Impregnation with barium calcium aluminate is effected at 1900 DEG C. and after forming grooves by milling, a layer of tungsten powder 1.3-3.5 microns in size is applied to the surface as a suspension in water and sintered at 1900 DEG C. in vacuo or hydrogen.

Chases.-A chase is formed from laminations of rigid material or materials bonded together, at least the top and bottom laminations being stamped or completely out out of sheet-metal to form one - piece frame - like members. The laminations may be of sheet steel, alloys of magnesium, or alloys of aluminium, such as that known under the Registered Trade Mark " Duralumin." Metal laminations may be bonded together by the glue known under the Registered Trade Mark " Redux." The internal laminations may be of wood, paper or canvas impregnated with a plastic such as that known under the Registered Trade Mark " Bakelite," or may be of plastic. The internal laminations may be one-piece members stamped from steel or other metal sheeting, plastic, impregnated wood, paper or canvas, or may be built up from T-, L- or Z-shaped elements formed by stamping from sheet or by extrusion. The elements are so assembled that joints between them in each lamination are staggered relatively to the joints in adjacent laminations. When the material of the laminations has a grain, the elements of a lamination are so arranged in the various laminations that the grain is any one lamination extends at rightangles to that in adjacent laminations. The top and bottom one-piece laminations may be formed of channel-section, the internal laminations fitting into the channels and the edges of the channels of the two laminations touching and being bonded together. Specification 711,032 is referred to.

Abstract: 1292154 Cooling or heating liquids; heat exchange tubes BASS CHARRINGTON Ltd 10 Oct 1969 18402/69 Headings F4H and F4S A device for heating or cooling beverages comprises beverage exchange units immersed in a tank of liquid and each comprising two portions arranged in series, the beverage in the upstream portion having a higher centre of gravity than the beverage in the downstream portion. The arrangement thus takes account of the temperature gradient that will exist in the liquid tank when a beverage is being cooled. As illustrated, each heat exchange unit comprises a flattened coil 19 containing and  connected in series with a circular coil 20. Beer enters through a pipe 18 and passes through the coils to a distributer 22 from which it flows through pipes 23 to dispensing points. A strengthening member 21 is provided and the unit stands on feet 24. In a modification, Fig. 6 (not shown), the coil 20 is replaced by a cylinder of similar dimensions which may be finned. In another embodiment, Fig. 5 (not shown), the unit comprises a cylinder and a circular coil which are connected in series and arranged side by side. The heat exchange units are immersed in a tank of water which is cooled by a refrigeration unit, Figs. 1 and 2 (not shown). A further heat exchange unit may be located at the bottom of the tank and used to cool a beverage which is dispensed less frequently than that cooled by the primary units. The further unit may take the form of a pipe having two portions of sinuous form arranged in adjacent horizontal planes.

Title: Method and apparatus for geophysical exploration

Abstract: 1,011,604. Locating conductive ore bodies. NEWMONT MINING CORPORATION. May 9, 1963 [Nov. 28, 1962], No.18436/63. Heading G1N. A method of detecting the presence of a subsurface conducting ore body comprises:- (1) establishing a primary magnetic field in a selected region by passing a current pulse through a transmitter coil and terminating the pulse linearly over a predetermined time interval, and (2) measuring the voltage induced in a receiver coil by the transient secondary magnetic field after the complete termination of the current pulse. The pulse of primary field is produced in a coil 32, Fig. 14, by a D.C. power source 73 and contacts S1 of a relay 84, the switch being controlled by a timing pulse generator 78, and a pair of reversely disposed Zener diodes 76, 77 being provided across the coil to produce a linear decay of coil current when the contacts are opened, the current having been of sufficient duration to establish magnetic quiescence. The timing is made adjustable by capacitors 82, 83. The current pulse is described with reference to Fig. 13 (not shown). The resulting current pulse 35a Fig. 12 picked up by receiver coil 34 is applied via an attenuator 45 to a relay and low pass filter 44, the relay of which is operated at time t2 on the current pulse shown, i.e. at the termination of the linear decay period, by a triggering circuit, coil 33 of which is tightly coupled to the transmitter coil. The leading edge of the picked up trigger pulse operates a counter 37 which closes a relay 38 and applies the pulse to a delay circuit 39. The delay circuit is responsive only to position going pulse 40 which it delays until time t2 when it is employed to trigger a monostable multivibrator to produce a square wave pulse 43 having a time duration of 100 milliseconds (the apparatus read time). Pulse 43 operates relay 44 to pass the pulse 48 to a D.C. amplifier 49 the output of which is sampled on a time basis by gates 1-3, and applied through integrating amplifiers to respective meters 58, 65, 72 the gates being controlled by multivibrators 1-3 and the succeeding gate being opened by the closure of the preceding gate. The merits of the arrangement are discussed with reference to a number of graphs, and arrangements for a more accurate determination by repeating the measurement with different transmit-receive coil spacings are described. The arrangement is said to give good results even in the case of deep bodies under a conductive overburden. The arrangement is said to be able to determine the conductivity of the body and the inclination of a tubular body, and the use of a charging current having its energy concentrated in the frequency region of 5-50 cycles is recommended. The arrangement is said substantially to eliminate the overburden response.
