Abstract: 554,685. Melting metals; alloying. WEBB, G. W., and PROCTOR, W. F. Oct. 13, 1941, Nos. 13159/41 and 2225/42. [Class 82(i)] [Also in Groups XI and XXIII] Metals, e.g. aluminium, are melted in a bath of molten inert material having a lower melting point than, and a different specific gravity from the metal, and a boiling point above the melting point of the metal, e.g., in a salt bath, which may include fluorides. A casing 1 contains a hopper 2 with refractory bars 3 to receive ingots from pre-heating chambers 4. The lower end of the hopper opens into a trap box 9 with a flanged valve seating which receives an inverted cup valve operated by a handle 13. Electrodes 15 are arranged in the hopper for heating the salts above the metal, and electrodes are arranged for heating the salts in the casing 1. The temperature may be controlled by a thermostat. The metal discharge tube 11 may also be provided with a thermostatically controlled heater. The outlet end of the hopper may be modified to provide a measuring chamber by which a measured quantity of molten metal is discharged at each operation ofthe valve. The valve seal may be of lead to avoid attack on the valve by aluminium. The lead seal may be omitted if the valve is of a material impervious to aluminium, and is sufficiently deep. In a modification in which the metal, e.g., magnesium or its alloys, is lighter than the salt, the hopper is inverted and the metal floats upwards towards the discharge passage. Instead of ingots, swarf may be melted, in which case it is fed from a container by a pusher, or conveyer, or through a tube with valve. In another modification, metals may be mixed in the hopper to form an alloy, by means of a helical rotary mixer.

Abstract: 1,234,199. Read only store. SIEMENS A.G. 11 Dec., 1968 [12 Dec., 1967], No. 58791/68. Heading G4A. A read only store having a conducting strip L1 on a carrier A, B passing through or passing by transformer cores passing through apertures O in the carrier according to the data stored, has the carriers stacked together with the strip on adjacent carriers connected the cores and interrogation terminals together in opposite directions. One carrier A has the terminals P1, P2 and the strip L1 coupled as shown in Fig 1 An adjacent carrier in the stack has the strip L2 connected to the terminals as shown in Fig. 2. If all strips were connected as shown in Fig. 1, stray capacitance between adjacent carriers caused by the large area of the terminals would cause current to flow in the carriers adjacent to the carrier being read. If the carrier being read stores " O " and the adjacent carriers store " I," the stray currents induce signals in the read out core representing a stored "I" and cause the difference between the " I " signal and the " O " signal to be diminished. If alternate A, B carriers are used, the stray currents introduced flow in opposite directions so that if a " O " is to be read stray currents in stores holding a " I " produce an increase of the difference between " O " and " I " signals in producing for instance a negative stray " I " read-out instead of the conventional positive " I " read-out. To obtain consistent read-out the input read-out pulse card A must be applied to the opposite terminal to that of card B.

Abstract: 1397900 Quadraphonic encoders SANSUI ELECTRIC CO Ltd 27 Dec 1973 [18 Sept 1973] 59868/73 Heading H4R Four sound channels 1-4 are encoded into two composite channels L T , R T  by coupling each channel in major and minor quadrature components to one composite channel and in minor quadrature components to the other. Thus L F  is coupled through reference phaseshifter 7 and through register R 3  (# 3 ) and phase shifter 8 to L T  adder 11, and is also coupled through R 1  (# 1 ) and phase-shifter 10 and through inverter 13, resistor R 6  (# 3 ) and phaseshifter 9 to R T  adder 12. The other sound channels R F , L B  and R B  are similarly coupled to produce signals Corresponding left signals are in phase but the right are in antiphase in the composite signals L T , R T . The ratio of the amplitudes of corresponding components in the two composite signals is ##1+ #<SP>2</SP> 2 : ###<SP>2</SP> 1  + ###<SP>2</SP> 3  and suitable choice of the #'s improves centre side signal separation and enables records thus encoded to be reproduced by a conventional stereophonic system in a more compatible manner than records encoded conventionally without the diagonal elements of Fig. 1. The #'s may have different values in left-right and right-left directions. For # 1  = # 2  = # 3  = 0À3063 the amplitude ratio of the corresponding signal components is the conventional 0À414 but there is no L c -R c  cross-talk between L T  and R T , rear signals are 152 degrees out of phase and C F  signals appear in L T  and R T  in-phase and at the same level for normal 2-CH stereo compatibility. For # 1  = # 2  = 0À4142, # 3  = 0À1715 corresponding front components in L T  and R T  are in-phase and rear components in antiphase but C F  signals have only 19 degrees phase difference, blurring the front image in 2-CH stereo, whereas L c  and R C  separation is 15À3 db. For # I  = 0À3714, # 2  = # 3  = 0À2, C F  components are in-phase, L F -R F  phase difference is 17 degrees, L c -R c  separation is 16 db and diagonal separation is 19À57 db. For # 1  = 0À383, # 2  = 0À330, # 3  = 0À2082 the phase difference between front components in L, T  R T  is 10À27 degrees and between centre components is 10À07 degrees. L c -R c  separation is 17 db and diagonal 25À35 db.
