Abstract: 1,248,550. Cultivating disc assembly. S. M. WEISS and R. G. SIMPSON. 4 Sept., 1970 [9 Sept., 1969], No. 42338/70. Heading A1B. A cultivating disc assembly comprises a cultivating disc 3, having a central aperture 8 from which radial slots 9 extend; a mounting member 4; and a keeper plate 12. Clamping bolts (not shown) are passed through the holes 7 and 13 and tightened so that the central portion 15 of the disc is firmly held between mounting member and keeper plate, the stems of the bolts extending through the outer ends 11 of the slots. This form of mounting enables the ends of the slots to move radially outwardly in the region of the bolts so as to permit the disc to behave elastically when distorted by working stresses and be less subject to fracture. Furthermore by placing these accommodating holes in a common keeper plate their stress concentration effect is confined to the keeper which may be made quite cheaply from a suitable steel or ferrous casting. The central portion 15 may be dished, as shown or it may be flat.

Title: Electric furnaces
IPC: H05B3/00
Filed: 1969-08-28
Abstract: 1,273,037. Resistance furnace. PERKINELMER CORP. 28 Aug., 1969 [7 July, 1969], No. 42946/69. Heading H5H. [Also in Division G3] A furnace, particularly for subjecting a sample to programmed temperature variations, comprises a resistive heating element and temperature sensor 32 with a non-linear temperature coefficient of resistance connected in parallel with a resistive element 36 whose temperature coefficient of resistance is substantially zero, so that in use the combined resistance temperature coefficient of the heating element 32 and resistive element 36 is more linear than that of the element 32 alone, and the resistive element 36 is also arranged to heat the furnace. As shown, a nickel heating foil 32 is formed by conventional printed circuit techniques on an insulating support 34 which is bent around the aluminium shell 12 of the furnace and a nickel-chrome resistive foil 36 is likewise formed on insulating support 40, and wrapped around the heating foil, the foils 36, 34 being secured by a metal clip 38 insulated from foil 36 by insulating material 40. The furnace may be used in various analytical apparatus e.g. a scanning calorimeter, a thermal gravimetric analysis instrument or a thermomechanical analysis instrument as shown. The heating element 32 and resistive element 36 are energized via a thyristor whose firing angle is controlled. Such control is effected by measuring the impedance of the temperature responsive parallel arrangement 32, 36 by making the arrangement part of a potential divider. A set point signal is provided by a second potential divider supplied by a D.C. source whose amplitude may be varied in accordance with the desired temperature programme. A chopper alternately connects the set point signal and the signal representing furnace temperature to a capacitor. The voltage from the capacitor is applied to an amplifier to produce an alternating voltage representative of the difference between the set point voltage and the voltage across 32, 36. This signal is applied via a D.C. amplifier to the S.C.R. trigger control circuit which effects an amplitude to phase conversion for controlling the angle of the S.C.R. and hence the furnace temperature.

Abstract: 1,071,632. Semi-conductor controlled rectifiers. SIEMENS-SCHUCKERTWERKE A.G. Oct. 21, 1964 [Oct. 26, 1963], No. 43016/64. Heading H1K. A four-layer semi-conductor controlled rectifier has one of its terminal layers embedded in that intermediate layer of opposite conductivity type which bears the control electrode. The concentration of uncompensated impurity centres in this intermediate layer decreases from its outer surface in a direction towards its junction with the other intermediate layer. The rectifier is so constructed that the concentration of uncompensated impurity centres in those parts of the intermediate layer immediately adjacent the embedded terminal layer is not less than 5 x 10<SP>16</SP> centres, cm.<SP>-3</SP> and that every current path between the control electrode and the electrode on the embedded terminal layer passes through a part of the intermediate layer in which part the concentration of uncompensated impurity centres is not greater than 10<SP>17</SP> centres, cm.<SP>-3</SP>. In the embodiment described an N-type silicon wafer is subjected to overall diffusion of gallium and aluminium to form a 70 Á P-type surface layer. An annular gold/ antimony electrode 17 is alloyed to this surface layer to produce a 23 Á N-type embedded zone 15. The doping level at the surface of the diffused surface layer is about 3 x 10<SP>18</SP> centres. cm.<SP>-3</SP> and is about 4 x 10<SP>17</SP> centres, cm.-<SP>3</SP> at the level of the PN junction formed by the embedded layer. A gold-boron is alloyed within the annular electrode to form the control electrode 18 and a similar foil alloyed to the other major face of the wafer to form the third electrode 16. The edge portions of the wafer are mechanically removed (e.g. by sand blasting) to form the four layer structure. That part of the diffused surface layer between the annular and disc electrodes 17, 18 is removed by sand blasting to a depth of 30-40 Áat which depth the doping level is about 10<SP>15</SP> centres. cm.-<SP>3</SP>. Thus every current path between electrodes 17 and 18 must pass through a region in which the doping level is no higher than about 10<SP>15</SP> centres, cm.<SP>-3</SP>. The surface of the recess formed is given a light after-etch to remove surface disturbances of the crystal lattice. In a variant, the surface conductivity of the intermediate layer may be substantially metallic.

Abstract: 1,159,254. Thyristor sawtooth generating circuits. RADIO CORPORATION OF AMERICA. 27 Sept., 1966 [8 Oct., 1965], No. 43196/66. Heading H3T. An electron beam deflection circuit, particularly for providing horizontal deflection in a television receiver, comprises a series resonant circuit 24, 27 in series with the primary of a transformer 26, the secondary 26b of which is tuned by a capacitor 30 and feeds deflection coils 29, a diode 31 returning energy to the supply 22 substantially throughout the trace portion of the deflection waveform. As described, each pulse from a horizontal oscillator not shown turns on thyristor 21, transferring energy from capacitor 24 to the primary of transformer 26 and giving a sinusoidal half cycle of current in the primary winding at the frequency of the series resonant circuit 24, 26, 27. The flyback current in the deflection coil 29 occurs at the same time and is formed by a sinusoidal half cycle at a frequency determined by secondary winding 26b and capacitor 30. The flyback duration may be equal to, less than or greater than the half cycle in the primary circuit. A further trace commences when diode 31 becomes conductive, thyristor 21 becoming non-conductive. The parallel circuit 24, 25 executes one half cycle of oscillation during the trace period. Flyback pulses are fed back to a phase comparator (not shown) which controls the frequency of the horizontal oscillator.

The liquid component of the solution consists of 0-10% by weight of one or more volatile hydrocarbon chlorides, at most 40% by weight of water, and the remainder one or more water-soluble lower aliphatic acids. The cellulose ester may be a cellulose acetate made by a process in which acetic acid alone or acetic acid and a volatile hydrocarbon chloride is employed as a diluent. The cellulose ester may be cellulose propionate or cellulose acetate butyrate. The granules of precipitated cellulose ester formed may be allowed to remain in contact with the precipitant for a time. The used precipitant may be diluted to precipitate residual cellulose ester material dissolved therein after having been separated from the cellulose ester precipitate previously formed. It may then be separated from the second precipitate, reconstituted and recycled to the main precipitation zone. As shown in Figs. 1 to 6, forms of apparatus in which the precipitation may be effected comprise a tubular or annular member 21 for extruding the cellulose ester solution into the stream of precipitant, the member being closed at its lower end 23 and being provided with a number of orifices 24 in its side wall. A tubular member 22 coaxial with and spaced from the member, 21 to form therewith a duct of annular cross-section communicates with a precipitant inlet pipe 25 and is provided with an opening 26 through which the suspension of granular precipitate in the precipitant is discharged. The top 27 of the member 22 is closed. The precipitant inlet pipe 25 is tangentially disposed with respect to the tubular or basin-shaped member 22 so that a gyratory motion is imparted to the stream of precipitant flowing through the duct between the members 21 and 22.
