Title: Improvements in and relating to wireless transmitters
IPC: H03B5/10
Filed: 1925-10-30
Abstract: 264,935. Im Thurm, J. K., Shearing, G., and Matthews, C. Oct. 30, 1925. Thermionic generators and amplifiers. - In order to maintain a constant frequency, the power amplifier V feeding the main auxiliary circuit L, C is connected to a local oscillator valve F through a resistance r, which carries only the exciting component of the current flowing in the local oscillatory circuit L1, C1. The ohmic losses in the resistance r are small, though high values of high-frequency potential are developed across the tapping points for energizing the power amplifier. The arrangement prevents interaction between the circuits of the amplifier through interelectrode capacity, whilst the tuning of the circuit L1, C1 is independent of the value of the resistance r. In an alternative arrangement the grid and filament tappings from the resistance r to the power amplifier are reversed and independent sources of supply are provided for the valves F and V respectively. Keying is effected by altering the value of the resistance r, either by cutting out part of the resistance or by using a separate shunt resistance. Specification 239,599 is referred to.

Filed: 1955-09-27
Abstract: 772,280. Bottle-filling machines. SOC. PARISIENNE D'EXPANSION CHIMIQUE S.P.E.C.I.A. Sept. 27, 1955 [Oct. 21, 1954], No. 27508/55. Class 94(1). Bottles 3 are fed in succession by a conveyer 4 into pockets 2 of an intermittently-rotatable table 1 to which is detachably secured an annular member 5 formed with holes 6 whose diameter is equal to, or slightly less than, that of the necks of the bottles. The first step of movement of the table positions a bottle below a tapered guide 7 through which a slub 8 of cotton wool is fed by a reciprocating comb 9<SP>1</SP> so as to form a compressed wad in the associated hole 6. The guide and table then move together from position A to position B, the wad is cut from the slub by a rotary knife 10 and the guide returns to position A to allow the next wad to be fed. The next step of movement of the table positions the bottle beneath a piston 12 which forces the wad to the bottom of the bottle where it expands to its original diameter to form a lining. The bottle is then positioned beneath a shoot 13 and receives a charge of tablets from an intermittently-rotatable, perforated, counting disc 14 to which the tablets are supplied from a hopper 15. The bottle is jigged during the filling operation. A clutch in the driving gear of the disc is controlled by a feeler, Fig. 3 (not shown), which is engaged by the bottle, so that the disc is not rotated unless a bottle is present to be filled. Subsequent movements of the table position the bottle beneath a guide 7<SP>1</SP>, knife 101 and piston 121 whereby a wad of cotton wool is inserted in the neck of the bottle, and the filled bottle is finally removed by the conveyer 4. The guides 7, 7<SP>1</SP> are secured together by arms 11 pivoted on the axis of rotation of the table 1 and are simultaneously rocked between positions A, B and A<SP>1</SP> B<SP>1</SP>. This rocking movement is utilized to drive the table through pawl and ratchet gearing.
