Filed: 1941-05-27
Abstract: 549,644. Wireless transmitting apparatus. STANDARD TELEPHONES & CABLES, Ltd., and WILLOUGHBY, E. O. May 27, 1941, No. 6784. [Class 40 (v)] The last valve V of a transmitter is coupled to an antenna AE by means of a coil LC in the aerial circuit coupled to the tuning inductance LV, LF of the transmitter output circuit which includes a condenser C and trimmer CT. The size and disposition of the coupling coil LC are so arranged that variations in the power transmitted due to variations in tuning of LV are automatically compensated by variations in the mutual inductance of the tuning inductance and coupling coil. The coupling coil LC may also comprise two coils in series. In this case (Fig. 2, not shown), the output and aerial circuits are not tuned to resonance. The coils LC are overcoupled at the short-wave end of the frequency range and this is compensated by means of the trimmer CT. This gives a suitable degree of coupling at the long-wave end of the range and a uniform power output throughout the range.

Abstract: 716,489. Making cartons. ROSE CONTAINERS, Ltd. March 20, 1952 [March 29, 1951], No. 7265/51. Class 18 Apparatus for forming carton bases and inserting them in tubular bodies comprises a punch and die for forming the bases and inserting them into a transfer member, and an ejector for forcing the bases out of the transfer member into the bodies. A cutter 14 cuts a disc from a web 12 and a plunger 21 passes it through a flanging die 19 into an aperture 26 in the cylindrical transfer member 27. The cylinder rotates to bring the base opposite an ejector 36 housed within the cylinder's open end. The ejection is attached to a tube 34 reciprocating on a stationary piston 44, and as the ejector advances, vacuum is created in the tube in front of the piston as soon as a hole 37 is closed by the base. The base is thus gripped and carried into a carton body 53 held in the pocket of a conveyer chain 49. The suction is broken when a hole 43 in the tube moves to the front of the piston. A reciprocating feeler 66 detects absence of a carton in a conveyer pocket by swinging forward to bring an abutment 64 out of register with a reciprocating abutment 63. This permits an element 58 to trip the pawl 71 of the rachet feeding the web 12. The Provisional Specification states that the conveyer is as described in Specification 716,490.
