Abstract: 429,841. Memorandum appliances. LAMSON PARAGON SUPPLY CO., Ltd., and GARWOOD, V. W., Paragon Works, Canning Town, London. Dec. 7, 1933, No. 34471. [Class 16] In an autographic register of the kind wherein a plurality of superposed paper record strips, interleaved with carbon sheets or strips, are fed from a compartment by feed mechanism over a writing plate, the record strips consisting of pre-printed individual forms each having aligning holes therein, and the register being so constructed that for each full movement of the operating means, a handle for example, a complete fresh form is placed in position and over the writing plate, means is provided whereby a card, paper strip, or the like can be inserted beneath the record strips in the register and beneath a carbon strip under the record strips and held there while the record is made on the top strip, this record appearing on the copy strips and on the card, paper strip, or the like. As shown, a bracket 4 secured to one of the side walls 1 of the register body carries a trough 5 for carbon papers which extend transversely of the register between longitudinally movable record strips. A member 6 comprising a bottom solid plate 9 which is the writing plate for the register, a top plate 7 with a writing aperture 8, and side walls connecting the two plates, is carried on the register body and is adapted to facilitate the insertion of a card or a strip beneath the carbon papers and record strips. The carbon papers, including an extra one at the bottom, are led over the member 6 and clamped by a bar pivoted on the latter and sharpened at one edge to serve as a tear-off bar, and a card or strip inserted at 14 between the plates 7, 9 will receive copies of entries made on the record strips. Where a strip is used it is fed by feed rollers 12, 13, which are geared together and operable by a handle. An extension 16 on the plate 9 on the withdrawal side of the member 6 acts as an additional writing plate. A window formed in the top plate 7 enables registration marks on the card or strip to be seen so that the latter can be registered in the member 6. The usual top cover 3 of the register is hinged on a bracket 2 on one of the side walls 1, and the aperture therein registers with the aperture 8. The outer edge of the cover 3 may serve as a tearoff edge for the carbon paper instead of the clamping-bar. The member 6 may have a transverse division to allow two cards or strips to be introduced, and two writing apertures may be provided in the top plate. A solid strip may cross the aperture 8 to prevent certain matter being copied on the card or strip. The member 6 may be replaced by a plate provided with side flanges on opposite sides thereof and connected by bridge pieces to guide the card or strip. Where a strip is used for the copy it may be fed from a drum or a zig-zag folded pack at one side of the register, and then rewound or packed at the opposite side. Specifications 136,116, 196,291, and 229,616, [all in Class 16], are referred to.

Abstract: 813,938. Improvements to high-frequency electronic oscillators. BRITISH THOMSONHOUSTON CO. Ltd. Nov. 19, 1957 [Nov. 21, 1956], No. 35606/56. Class 40 (6). [Also in Group XL (b)] A frequency-controlled high-frequency oscillator has a means of coupling the oscillator output both to a load and to a resonant circuit tuned to the desired frequency of oscillation. At least one element of gyro-magnetic material is included in the circuit so as to limit to a small amount the proportion of the output energy diverted to the resonant circuit but allow substantially all the reflected energy to return to the oscillator, the arrangement being such that the reflected energy tends to restore the frequency of oscillation to the desired value: In the embodiment shown in Fig. 1 two waveguide paths 1 and 2 are connected together by hybrid couplers 3 and 4 which are separated by a phase shifter 5 mounted in waveguide 2. Waveguide 1 is terminated at B by a load circuit 6 and waveguide 2 is terminated at C by a high-Q resonant cavity 7 and at D by a matched termination 9. The output energy of a magnetron oscillator 8 feeds into waveguide 1 at A. The phase shifter 5 is arranged to have a phase shift of 180 plus or minus 20 degrees in the direction D to C and substantially no phase shift in the direction C to D. Hence with energy fed in at point A the major part passes directly to the load 6, and only a small part is diverted into the cavity 7 due to the effect of the phase shifter. However, since there is no phase shift in the reverse direction substantially all the energy reflected from the cavity will return to the oscillator 8. In an alternative arrangement (Fig. 2, not shown) the load and the cavity are interchanged, and the phase shifter modified.
