Abstract: 322,820. Grupe, W. F. Aug. 14, 1928. Divided on 322,803. Cigarette-making machines.-A tobacco-feeding mechanism comprises a carded conveyer, for example a roller 13, Fig. 1, a picker roller 17, and a number of tobacco-projecting devices 19 arranged in series, to the successive action of which devices a stream of tobacco is subjected, so that tobacco is projected by each projecting device over a large area of a succeeding projecting device, or of a conveyer 23 supplying a succeeding projecting device. The constituents of the tobacco fall upon the conveyer or projecting device at positions nearer to or further from the projector according to 'the weight &c. of the constituents, forming over-lying deposits which gradually accumulate to the final thickness. As shown in Fig. 1, tobacco in a hopper 10 is fed by a belt 11 to the carded roller 13 and passes under a brush roller 15 and a comb 18. A picker roller 17 delivers the tobacco against director plates 21 and into the pockets of a tobacco-projecting roller 19 having vanes 20. The roller 19 projects the tobacco tangentially on to a carded conveyer roller 23 provided with a compressor roller 26, a comb 28, a picker roller 27, and a second projecting roller 19<a>, by which the process is repeated, the tobacco being confined between side walls (not shown). From the last conveyer roller 23<b> of the series, the tobacco is directed by the picker roller 35 into a hopper 36 leading to cigarette paper 37.

Title: Improvements relating to frequency dividing circuits
Inventor: WATSON EDWARD
IPC: H03K25/00
Filed: 1957-10-21
Abstract: 867,767. Pulse frequency-divider circuits. FAIREY CO. Ltd. Oct. 14, 1958 [Oct. 21, 1957], No. 32863/57. Class 40(6) A pulse frequency-dividing circuit comprises a capacitor the charge on which is varied in steps until at a predetermined value a Zener diode conducts to connect the capacitor to a re-cycling circuit which generates an output signal and discharges the capacitor after a predetermined number of input pulses have been applied. The Figure shows a pulse frequencydivider circuit in which pulses from the generator 10 are applied to a conventional "cup and bucket" circuit 11, 12, 13, 14. The voltage across the capacitor 14 decreases in steps at each input pulse until at a predetermined value the Zener voltage of diode 30 is reached. The diode then conducts to trigger the blocking oscillator circuit comprising the PNP junction transistor 20 so that the capacitor 14 is discharged and the cycle repeats itself. An output signal may be derived from the blocking oscillator circuit to indicate the application of a predetermined number of pulses. Preferably the transistor 20 is of the silicon type and the coil 24 is preferably shunted by a catcher diode 33. In a modification a valve blocking oscillator circuit is employed instead of the transistor circuit shown.

Title: Improvements in and relating to methods of making vacuum-tight connections between ceramic bodies and other ceramic or metal bodies
IPC: H01J5/42
Filed: 1937-11-29
Abstract: 506,520. Uniting metal to ceramic material by heat. BRITISH THOMSONHOUSTON CO., Ltd. Nov. 29, 1937, No. 32930. Convention date, Nov. 30, 1936. [Class 36] In effecting a vacuum-tight connection between two ceramic bodies, or between a ceramic body and a metal body, a crucible containing solder is arranged around the point of connection of the bodies and the whole is then heated to melt the solder, which runs between the two bodies and joins them. The crucible, or the part surrounding the soldered joint, is then removed. The crucible, which may be formed in a plurality of parts to facilitate its removal from the connected bodies, is preferably of graphite or of a metal to which the solder does not adhere. To avoid bubbles in the soldered connection, the heating of the solder may be carried out under reduced pressure, which is increased during the cooling-off of the soldered connection. When employing a soft solder the ceramic body may be pre-metallized at the points of connection. Fig. 1 shows a ceramic insulator 2 supporting the anode conductor 1 of a mercury vapour rectifier. Metal sleeves 3, 4, closely fitting the ends of the insulator are welded respectively to the anode conductor and the container 7 of the rectifier, the sleeves being soldered to the insulator by melting solder 10, 11 contained in crucibles 12, 13 surrounding the insulator, which crucibles are removed after the soldering operation. Due to the close fit of the sleeves on the insulator attack of the solder by mercury vapour during operation of the rectifier is minimized, as also is the possibility of leakage of solder, during the soldering operation, between the sleeve 4, and the insulator. In a modified construction the crucible is formed by the outer wall 14, Fig. 2, of an annular trough integral with the sleeve 4 and into which the lower end of the insulator is inserted. After melting and setting of the solder 17 the wall 14 is turned off or otherwise removed. Fig. 3 shows ceramic tubes 2. 18 and the flanged end 19 of a metal tube ready for connection together by solder 21 contained in a crucible 22.
