IPC: C04B2/00
Filed: 1916-08-14
Abstract: 102,928. Statham, N. Dec. 23, 1915, [Convention date]. Calcium carbonate in light condition weighing from 17 lb. per cubic foot to about 16.2 lb. per cubic foot, is produced by spraying milk of lime through an atmosphere containing considerably more than 20 per cent. by volume of carbonic acid.. Gas from a lime kiln 1 is passed through a washer 3 to carbonating-towers 7, 8 by means of a fan 11. Lime is slaked and converted into a thin milk in a hydrater 13, and is passed by a pump 18 to spraying-devices at the top of the towers. The liquor from the towers collects in a tank 9, from which liquor is also drawn by the pump 18. When carbonation is complete, the liquor is discharged to a filter 25, the carbonate being dried in a drier 26 without agitation, and, after disintegration, is sifted in a bolting-machine 27. The Specification as open to inspection under Sect. 91 (3) (a) contained a claim for precipitated chalk weighing not more than 17 lb. per cubic foot which does not appear in the Specification as accepted.

[Class 83 (iii).] A socket for securing a morse taper bit in a drilling-machine spindle 6 comprises an intermediate socket 2 shaped internally to fit the bit shank and a securing sleeve 10 rotatable on the spindle. The socket is provided at 4 with radial projections between which are adapted to engage driving lugs 5 on the spindle, the sleeve 10 also having internal recesses as shown in Fig. 5 to allow the socket to be inserted. In operation, the sleeve is rotated till its projections are in line with the lugs 5 whereupon the socket and bit are inserted and the sleeve then rotated to cause its projections to pass behind the projections 4 and prevent their axial removal. Spring pressed balls 13 located in axial recesses 15 in each of the lugs 5 co-operate with eight recesses 12 in the sleeve 10 in order to register and indicate the locked or open positions of the latter, the angular rotation necessary for changing from one to the other being only 45. Balls 9 are mounted between a collar 7 secured to the spindle 6 and a collar 8 secured to the machine and the sleeve 10 is located axially by an internal spring ring 11. The bit engages the socket 2 by means of a tang end which projects through the end of the socket to facilitate disengagement.

Abstract: 852,159. Frequency modulation. NATIONAL RESEARCH DEVELOPMENT CORPORATION. April 17, 1957 [April 20, 1956], No. 12226/56. Class 40(5). In an R-C phase shift oscillator the variable resistance of a pair of thermionic diodes D2, D1 connected in series with a modulating or bias source applied to terminals I produces variation in phase shift of the feedback from one valve VIb through the phase shifting path C1, Dl, D2 to the grid of another valve VIa having common cathode coupling with the valve VIb, so producing variation of the oscillator frequency. A network C4, R4, D1, D2 connecting thegrids of the oscillator valves linearises the frequency variation and counteracts changes in amplitude of the oscillations. In a modification the anode of D2 and cathode of D1 are connected to the cathode circuit of a triode valve whose grid potential is adjustable from a potentiometer so that the mean resistance of D1 D2 and mean oscillator frequency are adjustable. Further the resistor R4 may be omitted and the grid of VIb connected to the mid-point of a resistance connecting the anode of D2 and cathode of Dl. Resistors may be in series with D1, D2 to lower the mean frequency, and resistors may shunt the diodes to stabilize the lowest frequency generated. Further, the modulation may be applied to the terminals I through a cathode follower whose cathode load resistor is tapped and connected to the cathode of an output valve with grid connected to the terminal O, so that the D.C. level of the oscillations directly taken from the anode of the output valve is stabilized. In a further modification of Fig. 2 the resistor R4 is omitted and the grid of VIb connected to the tapping of a potentiometer connected across the input terminals I.
