Title: Improvements in or relating to the thermal treatment of magnesite, dolomite or lime
Inventor: REMMERS KARL
IPC: F27B15/00
Filed: 1965-10-11
Abstract: 1,128,932. Thermal treatment of magnesite, dolomite or lime. RHEINSTAHL ECO G.m.b.H. 11 Oct., 1965 [15 Oct., 1964], No. 43061/65. Heading C1A. Magnesite, dolomite or lime is subjected to a thermal treatment, e.g. at 1000-1670‹ C. to the point of deacidification (of magnesite, dolomite or lime) or sintering (of magnesite or dolomite) by conducting the material in the form of dust or fine granules, in counter-current with hot gas produced in a combustion chamber, through a plurality of centrifugal separators connected in series with or parallel to one another or in series/parallel arrangement relative to the flow of gas and/or the material drawn through the separators, the separators being adapted as required to be selectively connected in the said series, parallel or series/parallel arrangement by means of adjustable valves and by-pass pipes by which the material may be caused to by-pass one or more of the separators. The hot gas may be produced in an oil heated combustion chamber or a plurality of connected chambers and part of the gas drawn through the separators may be returned to the combustion chamber(s). Incompletely burnt gas may be produced in the combustion chamber and air required for complete combustion may be introduced into the gas flow at a point before or after the gas has passed through one or more of the separators. The material to be heat treated may be dried in a stream of hot gases which convey it to the separators. The residual heat in the treated material may be used to supply heat to air or other gas entering the combustion chamber. The material may be homogenized in a reaction container after the heat treatment. As shown in Fig. 2, air preheated by reaction product at 10 is passed into oil heated combustion chambers 1<SP>1</SP> and thence via cyclones 2-5 to dust extraction plant 6 where the product is recovered and passed to collecting chamber 9 and preheater 10. Combustion gases are withdrawn through the cyclones and dust extractor by means of fan 13 and partly recycled to the effluent from the combustion chambers in line 14. Material to be treated is supplied at 21 and first is dried in conduit 15. By means of valves 24, 26 and by-pass lines 25, 28 the material may be passed to line 14, line 14<SP>1</SP> or to the collector 9.

Title: Recording galvanometer
IPC: G01R5/04
Filed: 1965-10-19
Abstract: 1,117,243. Local circuits for electric meters. CLEVITE CORPORATION. Oct. 19, 1965 [Nov. 9, 1964], No. 44224/65. Heading G1Q. The position of the recording arm 34 of a moving coil recording galvanometer is sensed by a transducer 36 and the temperature of the moving coil 32 is sensed by a thermistor 30. The outputs of the transducer and the thermistor are connected to a feedback system controlling the galvanometer response in which the positiondependent feedback from the transducer ensures linearity and the temperature-dependent feedback from the thermistor corrects for variations of damping with coil temperature. The transducer output is fed to a detector 38 which passes a position-dependent current I p  to an amplifier 132 which drives the coil 32. The detector's position-dependent output is also passed to a network 133- whose circuitry is disclosed in Fig. 3 (not shown) -which passes a fraction of the position-dependent signal and differentiates the remaining fraction to provide a velocitydependent signal. This combined position-andvelocity signal is modified by the output of thermistor 30 and further differentiated by the capacitor 135 to provide a damping signal current I c  related to the velocity and acceleration of the movement but corrected for the effect of coil temperature on damping. The amplifier 132 is such that the input I 1  to be monitored, the position feedback current I p  and the damping signal current I c  are made to satisfy the relationship I 1  + I p  + I c  = 0. Thus when the movement is at rest (I c  = 0) I 1  = -I p , so that provided I p  is linearly related to recording arm tip displacement the latter is a linear function of I 1 . Strict proportionality between I p  and recording arm tip displacement can be attained by suitable design of the transducer 36: this aspect of the system forms the subject of Specification 1,117,242.

Abstract: 1398134 Boots &c BRITISH BATA SHOE CO Ltd 28 Sept 1972 [29 Sept 1971] 44839/72 Heading A3B [Also in Division B5] A method of forming a shoe sole from two thermoplastic materials of different colours comprises moulding an outer sole portion 26 and then moulding an inner sole portion 30 at a different location to interconnect the outer sole portion 26 and the lasted upper 32. The outer sole portion 26 is moulded in a cavity defined by a piston 23, sides 21 and a top mould (24), Fig. 4 (not shown). Top mould (24) is then replaced by a lasted upper 32 which is spaced from the outer sole portion 26 to form a mould cavity 28 for the inner sole portion 30. One form of suitable apparatus is shown in Fig. 7. A pair of mould pistons 35, 36 are mounted in a cylinder 38 which is pivotable about a horizontal shaft 40. In the first moulding step the piston 35 cooperates with a lower mould 41 to form the outer sole portion 26. Cylinder 38 is then rotated so that piston 35, carrying the outer sole portion 26, can cooperate with an upper mould, defined by a lasted upper 37; sides 46 and outer sole portion 26, so that the inner sole portion 30 may be formed. While the second step is being carried out, a further outer sole portion is moulded on the now lower piston 36. In another form, Fig. 9 (not shown) the apparatus comprises a piston (51) slidable in a cylinder (53). In the first step, piston (51) is lowered and the outer sole portion 26 is moulded in the cavity defined by sides (52). Sides (52) are then moved apart to allow piston (51) to be raised to cooperate with a lasted upper and new side moulds to form the inner sole portion. In a modification, Fig. 11, conventional side moulds 57 are used. In the first step, a dummy last 60 is used. In the second step, piston 51 is raised and dummy last 60 is replaced by a lasted upper.

Abstract: 1407088 Radio signalling SIEMENS AG 29 Sept 1972 [22 Oct 1971] 45013/72 Heading H4L A multichannel telecommunication system is provided with means for automatically switching over to a spare channel in the event of a fault in a radio link. As shown in Fig. 1, a radio relay system is provided with operational channels I to IV and two substitute channels. A filter W feeds six radio receivers ME whose outputs a1 to a6 are connected via receiving switching network NE to a transmitting switching network NS whose outputs c1 to c6 are connected via respective transmitters MS and common filter W to a transmitting aerial. The remaining relay stations are connected similarly and may include transmission line sections, the return path being identical. Four supervisory channels are provided for transmitting back to the transmitter of a link such as SA2 information regarding the condition of the respective channels I to IV and controlling the changeover to a spare channel. These signals may be transmitted via the return link or by a special line or radio link. Each supervisory channel has a transmitter KS which may be switched to transmit one of three frequencies to an associated receiver KE under the control of receiving network NE to denote that operation is normal or to denote which of the two spare channels is to be utilized. Each transmitter KS1, Fig. 2, comprises an oscillator 4 which normally operates at frequency f 0  (system normal) or may be switched via line 1 or line 2 to frequencies f 1  or f 2  respectively. The output of the oscillator is filtered at 5 and supplied via a filter 6 in the receiver KE1, amplifier 7 and limiter 8 to a frequency discriminator 9 whose two amplitude maxima coincide with frequencies f 1  and f 2  which lie symmetrically above and below f 0 . Frequencies f 1  or f 2  produce a response in circuits 10 or 11 respectively which is used to effect the required switching. A circuit 12 produces a further signal at terminal 3 when either f 1 , f 2  or f 0  is present whereby in the absence of f 1  or f 2  the circuit is monitored. If a fault causes the signal at terminal 3 to be outside the normal range it may be arranged to maintain the switching state existing before the fault.

Patent GB-1049347-A (GB)
Title: Growth of calcite crystals
IPC: C30B9/12
Filed: 1964-11-06
Abstract: Calcite crystals are grown by mixing CaCO3 with a flux, the proportion of CaCo3 being greater than that corresponding to the eutectic composition, heating the mixture sufficiently to render at least part of it molten without decomposing the CaCO3 and cooling at least part of the molten mixture to allow CaCO3 to crystallize out as calcite. In one embodiment the whole of the molten mixture is slowly cooled to cause gradual supersaturation.  When the predetermined end temperature is reached, the mixture is quickly quenched to room temperature. Alternatively, the temperature of the mixture is maintained higher at the bottom than at the top, the temperature at the top being sufficiently lower than that at the bottom to cause supersaturation of molten mixture carried upwards by convection; under these conditions an excess of solid CaCO3 is preferably kept in contact with the mixture at the bottom and one or more seed calcite crystals may be added to the upper region.  Quenching is carried out after all the excess CaCO3 has been transported from the bottom to the top of the mixture. The calcite crystals are recovered by washing with hot water to remove the flux.  The method of the invention is usually operated at normal pressures in air but if temperatures above 800 DEG  C. are used, the process is carried out in a pressurized CO2 atmosphere.  Additives may be incorporated in the calcite, e.g. by adding to the melt metallic carbonates, for instance Cd, Co, ferrous, Zn, Mg, Ni or Mn carbonate. Specified fluxes are Li2CO3, Li2CO3/K2CO3, Li2CO3/KNO3, LiNO3 and CaCl2.
