Abstract: 1,230,212. Continuous casting; straightening. CONCAST Inc. 12 Sept., 1968 [12 Sept., 1967], No. 43519/68. Headings B3E and B3F. A continuously cast curved metal strand 17 is straightened by passage through the nip of a single pair of rolls 11, 12. The rolls are driven at equal peripheral speeds and engage opposing surfaces of the casting with a pressure sufficient both to plastically deform the casting and to prevent slippage between the casting and rolls. The thrust on the rolls can be varied by a screwdown mechanism 16. When casting slabs the working rolls are provided with "back-up" rolls (not shown) to relieve strain on the working roll bearings. As the casting passes through the nip of the rolls (at a point where it still has a molten metal core) it is preferably deformed by an amount at least equal to the cross-section of its molten core at the deformation point before deformation.

Abstract: 1,238,356. Accumulator. VARTA A.G. 31 Oct., 1968 [4 Nov., 1967], No. 51636/68. Heading H1B. An electric accumulator has a cell containing at least one positive and at least one negative electrode and a mobile body of aqueous electrolyte in direct contact with both the positive and negative electrodes in which the active material of one of the electrode forms during discharge compounds readily soluble in the electrolyte, and said electrode is provided at the base of the cell container, the base being electrically conductive or provided with electrically conductive inserts. In an embodiment, Fig. 1, the base of a cell container consists of a metal plate 1 made of for example Ag, Ni, or Cu, over which is scattered zinc powder 2 and thus forms the negative electrode. Positive electrode 3 which may be an oxygen, AgO or Ni(OH) 2  electrode is provided in the upper part of the container. Separator 4 may be a cellulose foil and a solution of KOH or NaOH may be the electrolyte. In an improved embodiment, Fig. 2, a set of additional negative electrodes 5 is provided between the positive electrodes 3 and is conductively connected to the negative base electrode 2, so that on charging zinc deposits preferably on upper electrode 5, the portion depositing in spongy form and not adhering firmly falls and contacts lower electrode 2. In a further construction, the external electrical connection between the two negative electrode supports is dispensed with, electrical connection then being established by the spongy zinc which is first deposited on the base electrode and accumulates until it contacts the upper set of negative electrodes 5. Zinc is then preferably deposited on the upper electrodes 5. When an oxygen electrode is used an additional electrode which serves as a positive electrode during charging is provided at the uppermost edge of the container, as the oxygen electrode cannot generally be used during charging.

Abstract: 1,265,203. Doppler radar; frequency detectors. SHORROCK DEVELOPMENTS Ltd. 14 Jan., 1970 [19 March, 1969], No. 14413/69. Headings H3A and H4D. In a speed measuring C.W. Doppler radar the received signals are mixed with the transmitted waves to give a Doppler frequency signal which is amplified and converted into a corresponding square wave signal whose amplitude is limited by a Zener diode, said limited signal being applied to a capacitor charging circuit connected to a meter which indicates the speed of the object. In apparatus for measuring the speed of vehicles or work emitted by a machine or the rate of liquid flow, C.W. signals from a Gunn diode feeding a horn aerial are reflected from an object and mixed with the transmitted signals in a mixer diode. The beat frequency signal is fed to a terminal T, Fig. 1, then through an amplifier stage, comprising transistors TR1-TR3, to a Schmitt trigger TR4, TR5, whose output is limited by a Zener diode D2 to Vz. This square wave is passed to a switch arrangement TR7, TR16 which allows alternately C2 to charge through TR7 and then C1 to charge to the voltage on C2 through TR16. The average current discharged through the meter resistance connected to terminal X is thus proportional to C2, Vz and the beat frequency. In a first embodiment the meter has switched resistors (LR) connected in parallel to adjust the range of the meter, (Fig. 2a, not shown). In a second embodiment, Fig. 3, the signal from the capacitor C1 is filtered and passed through a F.E.T. voltage follower TR8, TR9 to the collector of TR10. Capacitor C3 is charged for positive-going signals and is prevented from discharging by diode D3, the voltage follower TR11, TR12 feeds back to the gate of TR9 providing a linear voltage-to-current converter. Meter M applied to terminal M is placed in series with range switch resistors to indicate speed. The meter may be reset by discharging C3 either manually by switch SW or automatically. In the automatic mode, the removal of the input signal causes TR9 to conduct, turning on TR14, after a delay caused by the R.C. network, TR15 is switched on, operating a relay K to close contact K1 to discharge C3. A push-to-read facility may be provided which earths C3 until a button is depressed whereon the speed is indicated.

The foam metal may be produced by spraying or electro-depositing metal on a polyurethane foam material, or by dipping such a material in metal, and then heating to "ash out" the polyurethane. As shown, each friction element 1 comprises a layer 3 of foam metal embedded in a carbon block 4 adjacent to the surface 5 of the block which is to be attached to a support member 2, Fig. 2. Element 1 is formed by impregnating the foam metal layer 3 with a resin-bonded composition including powdered graphite or other form of carbon and subsequently carbonizing the whole to form the block 4. The part of the pad containing the foam metal layer may be made separately (where the metal cannot withstand the relatively high graphitization temperature) and subsequently bonded to a graphite moulding to form the composite article. The metal of layer 3 may be nickel, steel, copper or molybdenum. The support member 2, Fig. 2, (showing a brake rotor or stator in cross-section) may be steel, beryllium or graphite reinforced with carbon fibre. The friction element 1 is pressed to shape, leaving clearance holes 6, before carbonization, and afterwards is secured by rivets 7. In Fig. 3 (not shown) the density of the foam metal layer is increased around the rivet holes and along the radial abutment edges, and counter-sinking extensions are provided around the rivet holes. In Fig. 4, on the other hand, the density of the foam metal layer increases progressively or stepwise from the interior outwards. In Fig. 5 (not shown) a sheet metal backing plate (51) is brazed or soldered to the "foam metal" face of the block and is dimpled at the rivet holes to engage countersunk depressions in support member 2. In Figs. 6 and 7 (not shown) the foam metal layer extends beyond the radial edges of the block, and the rivets pass only through these extensions; the extensions may be densified by impregnation with brazing or other metal. Riveting may be replaced by welding or brazing in this embodiment.
