Title: Improvements in the production of ferrites
IPC: C04B35/26
Filed: 1951-12-20
Abstract: For the production of ferrites, used in particular for magnetic purposes such as the preparation of magnet cores, there is employed ferric oxide obtained by burning iron carbonyl in excess of air, suitably at 500-700 DEG C., the ferric oxide being then combined with the other component of the ferrite.  Thus it may be intimately mixed with solutions of metal salts, e.g. nitrates, acetates, formates, sulphates or chlorides, and the mixture heated to cause ferrite formation, a temperature of 1000 DEG C. being specified for a mixture containing 50 per cent. Fe2O3, 25 per cent.  MgO and 25 per cent. ZnO.  The mixture may be heated in steam when the more difficultly decomposable salts, e.g. sulphates and chlorides, are used. Ferrites of zinc and manganese, and zinc and nickel are also referred to.

Title: Television transmitter
IPC: H04N5/073
Filed: 1935-10-31
Abstract: 465,185. Television. RADIOAKT.- GES. D. S. LOEWE. Oct. 31, 1935, No. 30035. Convention date, Nov. 2, 1934. Addition to 465,184. [Class 40 (iii)] To synchronize interlaced scanning, the edge of the image 12 to be scanned is bordered by an optically produced synchronizing - line 13, of which the light intensity exceeds the extreme value in the image and the length is greater than the height of the image. The framing- signal is produced by two slits 14, 15 in the scanning-disc 9, which are outside the scanning- area but within the line 13 and are staggered to the extent of the length of a scanning-line. The width of the slits is equal to that of a few scanning-apertures. Image signals are prevented from interfering with the synchronizing signals by making the width of the image less than that of the scanned area and using the line 13 to make up the width to the length of a scanning-line. The width of the line 13 is equal to that of several scanning- apertures and is so regulated by wedges 16, 161 that the two framing-signals are of equal intensity. The line 13 is so sloped that, despite its displacement relatively to the meridian 17, the framing-impulses are exactly staggered to the extent of one scanning-line and the two sets of scanning-lines accordingly engage correctly. A diaphragm, Fig. 3 (not shown), rotates at half the speed of the scanning- disc and has a spiral slit to expose the scanning- apertures and two windows, which are staggered to expose the slits 14, 15 correctly, and are followed by spokes to darken automatically the later part of the return lines at the receiver.

Abstract: 1,045,755. Selective punching apparatus. TELETYPE CORPORATION. Aug. 1, 1963 [Aug. 16, 1962], No. 30550/63. Heading B4B. Punching apparatus comprises a plurality of punches 82 each operable by a pivotallymounted lever 55 to perforate a record tape, a plurality of elements 20a to 20h selectively movable in accordance with coded input information, spring-influenced pivotally-mounted levers 42b to 42h for sensing the elements 20a &c. to control the levers 55 in accordance with the input information, and further levers 42a, 42k for recognising a given code combination, e.g. an answer-back code combination, so as to move additional levers 55 to provide additional perforations in the record tape thereby altering the recording of the given code combination. The elements 20a to 20h, Fig. 2, are extensions of selectively-settable code bars 137 of the printer disclosed in Specification 1,021,027. In the example described, the input code combination has marking signals in the 0, 4 and 5 levels and spacing signals in the remaining five levels. Accordingly, only the code bar extensions 20a, 20e and 20f, Fig. 4, will be moved to the left in Fig. 2. As shown in Fig. 4, all the code bar extensions have tines 41, the extensions 20a, 20e and 20f have additional tines 100, 102 while the remaining extensions have additional tines 101, 103. The levers 42b to 42h have tines 43 for sensing the tines on the code bar extensions while the levers 42a, 42k have continuous tine bars 43.for sensing the tines 100 to 103. As disclosed in Specification 1,038,516, when a pivotally-mounted driving bail 56 is moved counterclockwise, all the levers 42 move upwardly under the action of their springs 48 but those in which a tine 41 on the code bar extension is sensed by a tine 43 will be blocked from further upward movement whereas the others will move further upwardly into a position where each shoulder 75 on a projection 70 will be raised above the opposed shoulder 74 on an associated pawl 73 whereupon the pawl will be moved counterclockwise about its pivot 77 under the influence of spring 76 to latch the pawl to the lever 42. At this juncture, the bail 56 is moved downwardly and through lugs 57 drives the sensing levers downwardly against the bias of their springs 48, 76. Those of the sensing levers that are latched to pawls pull the pawls downwardly and rotate the respective levers 55 about pivot shaft 80. The latched pawls and levers 55 associated with levers 42b to 42j cause the corresponding punches to perforate the record tape. Upon downward movement of the levers 42a, 42k, the associated levers 55 move a driving bail 111 into driving engagement with lugs 106 on additional levers 55 to cause further punches to perforate the tape. The levers 55 having lugs 106 are those corresponding to the code bar extensions 20b, 20c, 20d, 20g and 20h.

[Class 138 (ii)] [See also Groups XVIII and XXIX] In apparatus for delivering measured quantities of liquid from one or more tanks 4, 5 to a washing machine (not shown), each tank is provided with a number of discharge openings 16 arranged at different levels and adapted to be rotated in sequence to a position over a discharge open ing 13 from the tank so as to deliver the content! in successive meas ured quantities, the rotation being effected by energy stored up during the opening of the drainage valve of the container and released when the valve is closed. The discharge pipes 16 are carried by a plate 14 rotated through a spindle 15 by means of a ratchet wheel 17 actuated by a pawl 19 on an arm 18 mounted at one end on the spindle and connected by a cable 21 to a weight 20 and to the drainage valve mechanism. When the valve is opened the pawl moves over a tooth of the ratchet which is rotated by the weight 20 when the valve is closed. The I tank is filled from a valve 8 controlled by an arm 23 carrying a float 9 resting, through an arm 22, on the surface of the ratchet. As the ratchet is turned after the tank is empty, the arm 22 falls into an opening 24 therein, thus opening the valve 8 and preventing further rotation of the ratchet. A sub-tank 10 arranged around and beneath the float 9 and having a bottom port adapted to be opened and closed by a float valve 12 as the level in the main tank falls and rises, ensures that the valve 8 remains fully open until the main tank is filled to the level of the top of the subtank and then quickly closes.
