Title: X-ray examination of objects
IPC: A61B6/03
Filed: 1974-08-06
Abstract: 1434153 X-ray apparatus SIEMENS AG 6 Aug 1974 [6 Aug 1973] 34677/74 Headings H5R and H4F To produce a chart of the distribution of effective atomic number in a thin cross-section of an object 4, e.g. a human body with trunk 3, two narrow beam X-ray sources, 6, 7 of different photon energy with associated scintillation detectors 8, 9 are scanned on rails 13, 14 to cover the same series of parallel tracks as in scan I, the ring 2 on which the sources and counters are mounted then being rotated through a small angular step about axis 5 through the object. The next scan is made after return to start, or in the reverse direction, the whole process being repeated until 180 degrees of rotation has been covered. For each detector the matrix of digitized outputs for n tracks at W angular steps is inverted to give the absorption coefficient at each of the nÎn points at which orthogenal sets of tracks I and III intersect. The ratio of absorption coefficients at the two photon energies is calculated for each point and translated by the computer from a stored conversion table into effective atomic number or a function thereof, displayed in digital values on printer 20, and in analogue shades of grey on viewer 21. In scanning, the digitized output from each detector enters the computer store from the instant when the beam first cuts the object until it leaves, totals for corresponding elements from each detector being stored correspondingly. In place of linear and angular movement of the sources and counters the object may be moved equivalently.

Abstract: 1513188 Television SONY CORP 21 Aug 1975 [29 Aug 1974] 34814/75 Heading H4F X-Y matrix type display panel 11 control arrangement comprises "write in" memory circuits W 1 -W K  for the column lines Y l -Y K  of the display panel, each circuit including four flip-flop circuits F A1 -F D1  into which binary coded (i.e. four bits) video signal samples from coder 22 and level detector 21 are sequential fed under the control of clock pulses C w  from oscillator 23 which is triggered by the horizontal sync start pulses S H  i.e. the "write in" memory circuits W l -W K  are loaded with each line of video signal samples by shifting each bit along the lateral shift registers W A -W D  formed by the flip-flop circuits F A1 -F Dk , the lower order bits of each video sample being stored in flipflops F A1 -F AK . These bits are transferred, under the control of read pulses C T2  from oscillator 26, sequentially into "read out" memory circuits R 1 -R K , which each include four flip-flops connected to form a shift register, from which they are sequential fed to the Y-column line driving transistors T Yl -T YK  by sequentially produced pulses C R1 , C R2  and C R3  from pulse generator 29. These latter pulses are delayed by <SP>1</SP>/ 15  T H , <SP>3</SP>/ 15  T H  and <SP>7</SP>/ 15  T H  from the transfer of signals with pulses C T2  so that discharging currents between the crossed X-Y conductors of the display are caused to flow for different time periods (Fig. 5F-5I) corresponding to the weight (i.e. order) of the bits in the digitally coded video signal samples. The X row lines are driven line sequentially via driving transistors T X1 , T x2  ... Instead of transferring the bits from the "write in" memory circuits W l -W K  to the "read out" memory R l -R K  sequentially in a series manner, the transfer may be effected simultaneously by connecting F A1 -F AK  to F El -F EK , F Bl -F BK  to F Fl -F FK  etc. The display panel may comprise a gas discharge, liquid crystal or electroluminescent panel.

Title: Electrical resistor and method of making same
IPC: H01C7/00
Filed: 1955-12-05
Abstract: 794,848. Electric heating resistance coatings. PRITIKIN, N. Dec. 5, 1955 [Dec. 17, 1954], No. 34818/55. Drawings to Specification. Class 39(3) [Also in Group XXXVI] An electrical resistor which may be used for heating is produced by depositing an iridized coating of metal oxide on a preformed inorganic insulating base and protecting it by fusing a film of glass to the surface of the coating. The base may be of glass or ceramic and the iridized coating may comprise tin, indium, cadmium with or without small amounts of zinc, copper, iron magnesium, cobalt and vanadium or tin and antimony or oxides of the above metals. The coating may be produced by mixing a salt of the desired metal in a liquid carrier and spraying this on to the heated base. Terminals of noble metal are formed either under-or overlying the iridized coating, the coating may be etched away to provide areas for application of the terminals. The protective coating of glass may be sprayed in a molten state on to the iridized coating the base preferably being heated and parts which it is not required to protect being masked from the spray. Alternatively a glass sheet may be laid over the coating heated and pressed into intimate contact with the coating. A glass frit may be used as the protective coating it being fused to form a continuous film over the iridized coating or it may be applied by means of a screening process. The glass sheet or frit should preferably have the same temperature coefficient of expansion as the base of the resistor.

Title: Improvements in or relating to the preparation of monosodium novobiocin
IPC: C07H17/075
Filed: 1962-09-12
Abstract: Crystalline monosodium novobiocin is prepared by neutraliizing novobiocin dispersed in acetone containing from 2% to 25% by volume of water to produce monosodium novobiocin, crystallizing the thus-produced monosodium novobiocin by decreasing the concentration of water to less than 1.5% by adding acetone, adding about 1/2 volume of an inert organic solvent, particularly a hydrocarbon solvent, and recovering crystalline monosodium novobiocin.  The neutralization of the novobiocin can be effected with sodium hydroxide, a sodium alkoxide or a sodium salt of an acid having a dissociation constant less than that of novobiocin.

Abstract: 483,865. Clocks. BOWELL, G. B. Dec. 31, 1936, No. 35803. [Class 139] Striking mechanism for synchronous motor clocks is driven from a continuously running motor by a friction drive connection 5, 10, pressed into action by the release of the letting- off piece 13 through the intermediary displacement of a sector 17 which presses against a rotating surface A of the striking part 11, the sector being thereby rotated to its disconnecting position. A motor-driven spindle 1 is geared to drive the minute hand arbor 2 which, in turn, drives a gear-wheel 15 and ratchet-wheel 16, mounted on the letting-off piece 13, at the rate of one ratchet tooth per hour thereby controlling the position of the sector 17 by means of a spring click 18. At each quarter the sector 17 is released to bear upon the hub A and engages the friction wheels 5, 10 by tilting the bar 7 about its pivot 6.
