Abstract: 422,289. Ink-ribbon mechanism; ink ribbons. PELTON, G. E., The Popkins Farm, Alexandria, Virginia, U.S.A. Sept. 16, 1933, No. 25684. [Class 100 (iv)] Ink is supplied to a typing-ribbon by applying a finely gauged, evenly distributed, narrow film of ink to a narrow, non-absorbent, supplyribbon which interwinds closely on the spools with the typing-ribbon. The supply-ribbon may consist of silk fabric, preferably made from long-fibre threads, impregnated with a starch or tracing-cloth solution, adhesive being sometimes employed for closing the pores. The supply-ribbon may be calendered, preferably on the face to which ink is applied, the finished supply - ribbon being about twothousandth of an inch in thickness. The material known under the Registered Trade Mark " Cellophane " may be employed for the supply-ribbon. The ink-applying apparatus may comprise means such as a valve or wick for fining down a stream of ink from a reservoir, and means such as an apertured plate for gauging the width of the film to be applied, the apparatus being devoid of moving parts. A form of such apparatus is shown in Figs. 1 and 2 and comprises a reservoir 10 provided with one or more fine nozzles 11, regulated by needlevalves 20, for applying ink to a narrow supplyribbon 12 which passes along a guide 18 and interwinds on the spools 13, 14 with the typing- ribbon 15. The guide is provided with a resilient lining 19 of cork, felt, or the like and the reservoir is provided on the front with projections for stretching the supply-ribbon as it passes over the nozzles. When a supplyribbon calendered on one face is employed, the dull face is arranged in contact with the lining 19. The guide-channel is carried by a hinged flap 30. Each valve 20 is arranged in a tube 21 and is provided with a grooved collar 22 for cutting off the supply of ink to the nozzle. The nozzles are of different diameters and are adjusted or cut off to regulate the amount of ink delivered. To determine the position at which ink is supplied to the typing-ribbon, the reservoir is adjusted vertically by means of nuts. In an alternative apparatus shown in Fig. 7, the supply-ribbon 12 passes over a pulley 33 having a jacket 35 of felt or the like, and receives a narrow film of ink from a serrated disc 32 running in contact with a roller 31 to which a broad film of ink is supplied from a reservoir 10 by means of a wick 30.

Title: Improvements in or relating to electromagnetic devices for modulating the amplitude of high-frequency waves
IPC: H03C7/02
Filed: 1952-10-16
Abstract: 719,517. High-frequency impedance networks. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Oct. 16, 1952 [Oct. 19, 1951], No. 25988/52. Class 40 (8). [Also in Group XL(c)] Amplitude modulation of electromagnetic waves passing along a wave guide 13, 14, Fig. 4, is effected by a gyromagnetic member, preferably a ferromagnetic member 16 of substantially non- conductive material which is subjected to a magnetic field created by the modulating current, the wave frequency being greater than the natural gyro-magnetic resonance frequency of the member. One face of the wave guide has a branch tube 19 within which a co-axial member 18, 20 is adjustably fitted, the inner conductor 18 projecting into the guide at one end and being looped around the member 16 at the other end. The outer conductor 20 which may be of rectangular section, makes sliding contact with the tube 19 and is separated by insulation 15 from the inner conductor 18, which may be of ribbon shape. The member 16 is pre-magnetized by a permanent magnet 17, and the modulating current causes a variation in the impedances of the wave guide. The member 16 may lie across a diameter of an insulating ring -inserted in the outer conductor 20, Figs. 5 and 6 (not shown). In Fig. 1, a wave source 1 feeds through a guide 2 a pair of oppositely-directed guides 3, 4 one terminating in a dummy load 7 and the other in a radiating horn 8. Modulators 5, 6 branching from the respective guides in the manner shown in Fig. 4 have their respective, ferromagnetic members 16 energized in phase opposition by the modulating current. This results in variable reflection of the waves at the modulators, but the impedance presented by the guides 3, 4 jointly is substantially constant, and the frequency of the wave remains unchanged. In a modified arrangement (Fig. 2, not shown) a straight wave guide connects the source 1 to the horn 8 and includes the modulator 5, whilst the modulator 6 is included in a branch guide terminating in an adjustable piston.
