Title: Improvements in or relating to telecommunication systems and apparatus
IPC: H04B7/155
Filed: 1952-10-24
Abstract: 732,798. Automatic frequency control systems. GENERAL ELECTRIC CO., Ltd., and ASPIN, J. J. E. Nov. 25, 1953 [Oct. 24, 1952], No. 26763/52. Class 38 (4). [Also in Group XL (c)] An oscillator, e.g. the local oscillator 3 of the receiver of a relaying station, has its frequency controlled by passing part of its output to a standard resonator 8 either whose tuning is modulated about a mean frequency equal to the frequency to be controlled, or the oscillator itself is slightly frequency modulated so that the resonator output is phase or amplitude modulated with a phase or phase sense corresponding to the sense of frequency error, which phase is then detected and applied to correct the frequency through a servo control 14. Further, the second harmonic of the modulating frequency fm present when the oscillator is at its correct frequency is detected by a filter 13 and applied to operate an alarm, indicator or control 16 when the amplitude falls below a predetermined level. Thus any failure of the local oscillator 3 or A.F.C. system causes operation of device 16. In addition a monitor 17 responsive to the D.C. output of the receiver frequency changer 2 may check the latter and the output from the local oscillator 3. The monitor 16 may operate a supervisory tonemodulated generator 18 which injects the appropriate intermediate frequency fi into the amplifier 4 if the preceding part of the relay station fails. Alternatively, as described in Specification 664,016, [Group XL (c)], the sysmay effect change-over of faulty transmitting apparatus.
Patent GB-693956-A (GB)
Title: Improvements in or relating to storage electrodes for use in signal converting electron discharge tubes
IPC: H01J29/43
Filed: 1951-11-15
Abstract: 693,956. Cathode-ray tubes. RAULAND CORPORATION. Nov. 15, 1951 [Nov. 15, 1950], No. 26764/51. Class 39(i) A storage electrode for a signal converting tube comprises a foraminated structure such as a mesh 12, Fig. 3, covered on one side with an insulating film 13 of which the portions covering the interstices of the mesh are coplanar with the central plane thereof, and on the other with photoemissive material 14, leaving the insulating film exposed. The mesh may be of gold or chromium, possibly plated on to copper. The photoemissive material may be a conventional caesium/antimony or caesium/silver-oxide mosaic structure, and the film 13 may be any suitable insulating material although silicon dioxide is preferred. One manufacturing technique consists of forming an antimony layer on one side of a fine gold mesh, which is then covered with an organic film such as nitrocellulose, this film being drawn into the interstices of the mesh by surface tension. Silicon dioxide is then evaporated on to the other side of the mesh, completely covering mesh and interstices, as at 13, to a suggested thickness of 1000-8000 : after which the nitrocellulose film is dissolved away. The mesh electrode is then mounted within the tube, and photosensitized in the normal way. The mesh should be as fine as possible, since this determines the resolution, and the gold mesh of the above example has a thickness of .0002 in. and 400 openings per in. The storage electrode is used in tube 10, comprising cathode 22, control grid 25, first anode 29, second anode 33 closed at one end by a wide mesh screen 37, decelerating electrode 16, accelerating electrode 17, further accelerating electrodes 44, 45, which may be formed as wall coatings, and a metal-backed fluorescent screen 41. The secondary emission ratio for the insulating film 13, and hence the storage electrode as a whole, may be greater or less than unity, according to the voltage of the primary electrons. In order to condition the storage electrode for recording, its potential is raised, by tap 38 on potentiometer 31, to a value which gives a greater than unity value, so that a positive charge is built up. A charge pattern is established on the storage electrode by signals from a source 23 in the cathode circuit, or by causing the incoming signals to vary the potential of control grid 25. The photoemissive side of the storage electrode is illuminated from a source 42, so that an image pattern of photoelectrons is projected to impinge on fluorescent screen 41. Alternatively, the storage electrode may be conditioned by a flooding beam or a focused scanning beam from a separate gun. The tube is particularly suitable for half-tone storage and reproduction. Specification 677,300 is referred to.

Filed: 1959-08-06
Abstract: 886,207. Friction clutches. INSTITUT FUR FORDERTECHNIK LEIPZIG. Aug. 6, 1959, No.26921/59. Addition to 798,367. Class 80 (2). The multi-disc friction clutch of the parent Specification, in which a driving shaft 8 is connected to a driven housing 10 upon energization of an electromagnet 1 attracting an armature 2, secured to a sleeve 4 drawn rightwards of the Figure to compress a dished spring 5, abutting at its outer periphery 15 against a pressure -plate 12, thereby biased to engage clutch discs 6, 7 for the transmission of torque, is modified by replacing the disengaging helical springs arranged in the sleeve by a ferromagnetic dished spring 17 engaging between the outer periphery 18 of the armature and the inner periphery of the electromagnet. The dished spring 17 serves to guide the flux from the solenoid to the armature, thus increasing the magnetic force on initiation of a clutch-engaging movement. In the form shown, the electromagnet 1 rotates with the driving-shaft 8, but in a modification, Fig. 2 (not shown), the electromagnet is stationary and is mounted by means of a ball-bearing upon the driving-shaft.

Abstract: 210,820. Nicholson, E. G., and Aeolian Co., Ltd. Oct. 6, 1922. Winding-mechanism; tracker-bars. - Tunesheets of different widths are automatically guided by mechanism comprising three or more pairs of ducts, the ducts of each pair being at opposite ends of the tracker-bar and the pairs not in action being automatically ineffective. The three pairs of ducts c - - h, Fig. 1, are connected respectively to the two halves of a junction-block i, the connections from the middle pair of ducts e, f being crossed. Fig. 4 shows a section of one-half of the junction-box, with connections c<1>, f<1>, g<1> from the ducts c, f. g. The two chambers i<1> between two pairs of diaphragms as j<1>, l<1> in the junction-box, of which l<1> is the larger, are connected to suction at i<5>, and the two tubes as n<1> are connected to primary pneumatics n<3>, o<3> and valves n, o controlling the connections of coupled bellows r<1>, r<2> either to atmosphere or to suction at q<2>. A wide sheet normally will cover all the ducts c - - h, the diaphragms n<3>, o<3> being therefore cut off from atmosphere, and the valves n, o therefore connecting the bellows r<1>, r<2> equally to suction. If the tune-sheet moves, say to the right, the duct c is uncovered and the diaphragm j<1> is drawn from its seat, permitting atmosphere to pass from the duct c<1> by the tube n<1> to the diaphragm n<3>. The bellows r<1> being thus connected to atmosphere, the bellows r<2> collapses, moving the tune-sheet to the left. With a medium sheet, normally the bellows r<1>, r<2> are equally connected to atmosphere, the ducts c, d being both uncovered, but the uncovering of one of the ducts e, f will operate one of the diaphragms as l<1> to force the diaphragm as j<1> on to its seat and cut off the atmospheric connection through the tubes as n<1>, c<1> of one of the diaphragms n<3>, o<3> and connecting the appropriate bellows r<1>, r<2> to suction. With a narrow sheet, both bellows r', r<2> will normally be connected to suction ; but the uncovering, say, of the duct g will admit atmosphere directly by the tubes g<1>, n<1> to the diaphragm n<3> and connect the bellows r<1> to atmosphere. The bellows r<1>, r<2> are connected by a rod r<4>, adjustable in length, to an arm on a spindle u carrying cams s<5>, t<4> against which the roll spindles are pressed by springs s<7>, t<5>.

Title: Roller for a textile machine
IPC: D01G1/08
Filed: 1977-06-29
Abstract: The roller (10) has a metal sleeve (12) mounted on a shaft (11) by means of a rolling bearing. The sleeve (12) is surrounded by an inner tube (14) and an outer tube (15) which both consist of elastomeric material and which are connected to one another by vulcanisation. The material of the inner tube (14) consists of an elastomeric matrix, into which very short fibres oriented circumferentially and preferably consisting of cellulose are embedded. Consequently, in comparison with the outer tube (15) which consists of the hitherto conventionally used material, such as rubber or caoutchouc, if appropriate with suitable additives, the material of the inner tube (14) has a substantially steeper stress/strain curve than the elastomeric material of the outer tube (15). The roller (10) thereby withstands very much higher contact pressures, without the elastomeric material (14, 15) coming loose from the sleeve (12). <IMAGE>
