Title: Apparatus for visual presentation of digital and analog information
IPC: G09G1/14
Filed: 1962-02-14
Abstract: 988,379. Radar position markers. SPERRY RAND CORPORATION. Feb. 14, 1962 [March 16, 1961], No. 5699/62. Heading H4D. In a P.P.I. display in which a secondary highfrequency sweep signal gives out continuous digital information representative of r and o scanned and the computed position of an object, e.g. a missile, is also given in digital form in terms of rand o, the secondary trace is brightened up to show the predicted position of the object when the two sets of digital information from the computer and sweep signal are equal. The rotating radar aerial 10 is mechanically coupled to the rotor shaft of a low speed resolver 24 having its rotor excited by the sweep signal shown to give sine and cosine sweep signals on lines 32 and 34. These signals are then fed, via sweep switch 36 to the deflection plates of the C.R.T. 45, to produce, in a known manner, the normal P.P.I. display. The invention lies in the provision of a secondary sweep circuit operating at, say, 100 times the speed of the normal sweep circuit and comprising a high-speed gear portion of train 22 coupled to a high-speed resolver 26 having its rotor fed with high-frequency sweep signals from generator 30 and feeding the resolved signals to the switch 36 for feeding, under certain conditions, to the C.R.T. deflection plates. The angular position o of the secondary sweep is determined by a magnetic or photo-electric pick-up 52 scanning the high-speed gear 22 and feeding pulsed signals, via amplifier 54 to counters 48. The instantaneous range r represented by the secondary sweep signal is given by the range gate 64 feeding a pulse signal equal in width to the said sweep signal to one input of an AND gate 62 to let through a series of high-frequency pulses from generator 58 to a second r counter 50. The computed r, o position of the missile &c. is stored in digital form in register 74 and is compared in a multi-input coincidence gate 72 with the corresponding r, o counts in counters 50 and 48. When the latent secondary trace is in the computed position on the C.R.T. screen, the counters 50 and 48 have counts equal to those in the register 74 and the gate 72 sends a signal to the sweep switch 36 to switch the deflecting plates from the normal sweep signals to the secondary sweep signals, and also to a video switch 86 to cut off the normal C.R.T. grid signal and brighten up the trace to produce a spot on the C.R.T. in the computed position. The operation is started by applying a ready pulse to the range gate 84 for it to produce a secondary sweep controlling pulse, and to an AND gate 80 so as to pass the signal from the gate 72. The signal from gate 72 is also passed back to the computer to start it on a new computation.

Title: Manufacture of interpolyamides
IPC: C08G69/36
Filed: 1940-04-04
Abstract: 540,135. Resinous polymerization products. DU PONT DE NEMOURS & CO., E. I. April 4, 1940, No. 6090. Convention date, April 4, 1939. [Class 2 (iii)] Inter-polyamides are prepared by heating, at amide-forming temperature, 6-aminocaproic acid, hexamethylenediamine and adipic acid, or amide-forming derivatives of these, the aminocaproic acid or amide-forming derivative thereof constituting from 50-85 molar per cent of the total reactants, and the other reactants being present in substantially equimolecular proportions, until substantially all of the reactants have combined to form the interpolyamide. The preferred amount of 6- aminocaproic acid is from 55 to 75 molar per cent of the total reactants. It is preferable to add water to the original reactants in carrying out the initial polymerization, but after the initial heating with retention of water, the heating is continued with removal of water. Examples are given describing the preparation of interpolyamides from :-(1) 6-amonicaproic acid and hexamethylene diammonium adipate ; (2) caprolactam and hexamethylene diammonium adpate; and (3) E-aminocapronitrile and hexamethylenediammonium adipate. Plasticizers, viscosity stabilizers, pigments and antioxidants may be present during the reaction, and the preferred temperature range is 180- 300C. The products are useful in making fibres, filaments, sheets, films, moulded articles, electrical insulation, felting compositions, adhesive and coating compositions. Specification 461,237 is referred to.

Title: Improvements in or relating to the measurement of water-vapour content in a flow of gas
IPC: G01N7/10
Filed: 1960-02-22
Abstract: 941, 521. Estimating hydrogen in a gas stream; hygrometric apparatus. PHILIPS' GLOEILAMPENFABRIEKEN N. V. Feb. 22,1960 [Feb. 24,1959|, No. 6147/60. Addition to 846, 648. Headings G1B and G1S. In a method of determining the water vapour content in a flow of gas, as in the parent Specification, in which the water-vapour is decomposed to produce hydrogen and by means of suction the hydrogen is caused to diffuse through a semipermeable wall, such as a heated palladium tube 8, to a pressure measuring device 10, the suction is applied from pump 16 through an attenuating device, such as a capillary tube 13, so that although the partial pressure of the hydrogen at the measuring device 10 is hardly affected the partial pressure of other gases, such as carbon dioxide and carbon monoxide, which have diffused through the tube 8, is reduced to a negligible value. As in the parent Specification any free oxygen present in the gas flow may be removed by diffusion through a heated silver wall and any free hydrogen by diffusion through a heated palladium wall. Alternatively, after removal of free oxygen, the gas flow may be divided between two ducts 2, 3, the water vapour being decomposed only in tube 2. Heated palladium tube 9 and capillary tube 14 are similarly arranged to those 8,13, associated with duct 2 and the device 10 is in the form of a differential manometer, so that the effect of the free hydrogen diffusing through tubes 8, 9 is balanced out.

Title: Improvements in or relating to dynamo electric machines
IPC: H02K1/18
Filed: 1929-02-27
Abstract: 327,823. General Electric Co., Ltd., and Orsettich, R. Feb. 27, 1929. Rotary transformers; armatures and field magnets, cooling; reducing flexing of leads connecting fixed and movable members.-In a frequencyconverter wherein the stator is rotatably mounted, a curved surface, for example, a cylindrical surface is provided on to which a lead associated with the stator winding is adapted to wind as the stator is rotated, thereby avoiding serious flexing of the lead. The stator 1 of a three-phase generator forming part of a frequency changer can turn on rollers 3 carried by webs 7 forming part of an outer fixed structure 2. End shields 8 extend from the outer shell 2 to fans mounted on rings 11 on the rotor shaft 12. Further end shields 16 beyond the end shields 8 extend inwardly to the rotor shaft, thus serving totally to enclose the machine. Cooling air flows in a continuous circuit from spaces 17 at each end of the machine and is blown by the fans 10 past the stator end windings 46 through ducts 47 between the stator frame 5 and the core 25, radially inwards through ducts 19, radially outwards through other ducts 19 and through openings in the frame 5 between the ducts 47 into ducts 20 between the stator and the outer parts of the fixed shell 2. Rotor cooling air is led from the spaces 17 through channels 48 in the rotor shaft 12 under the rotor end windings 14, through longitudinal ducts 49 and through ducts 18 into the air gap whence it flows radially outwards together with the stator cooling air. Air from the spaces 20 flows out through the bottom of the machine and is led through a cooler back to the spaces 17. A channel 24 below the machine is in communication with the interior at each end. Connection to the stator windings is effected by six pairs of cables 26, three at each end of the machine. Each pair of cables is secured to a common terminal socket 103. which is clamped to a pair of terminals 17 and one wall of the channel 24. The other ends of the cables extend on to a cylindrical shell 31 which surrounds the stator end windings and are secured thereto by cleats 32, 33. At 35, the cables enter under the shell, and each pair is secured in a common terminal socket 102 connected to a terminal 40 mounted on an end plate 30 of the frame 5. Copper strips 41 connect the terminals 40 to the stator winding. The shell 31 is formed with annual flanges 37 and 100, the former fitting on an annular seating 36 on the frame 5 and the latter making a sliding but substantially airtight joint with an annular flange 101 on the endshield 8 so that there is no appreciable leakageof air into the space 51 between the shell and the part 44 of the end shield. The cables may be secured together at intervals by clamps 43 and are prevented from touching the wall of thechannel 24 by a roller 45.

Abstract: 1,148,932. Apparatus for scalding carcasses. H. PILLER. 16 Feb., 1966 [16 Feb., 1965], No. 6708/66. Heading A2U. Apparatus, Figs. 4 and 5, using circulating, hot, moist air for scalding animal carcasses, e.g. for scalding carcasses of pigs or poultry to facilitate debristling or plucking at 53, is in the form of a tunnel comprising adjacent scalding compartments 41 and 42 defined by walls 26 and 27 separated by a passage 40, transverse end-walls 43 provided with entrance and exit apertures 44, and a transverse partition-wall 51 provided with an aperture 52. An overhead rail 45, from which the carcasses are suspended and along which they are moved through the compartments 41, 42 passes through said apertures and has, in each compartment, a looped configuration, e.g. a horizontal loop comprising two parallel, straight portions 47 and 48, and curved, connecting portions 49 and 50. A curtain of air, from nozzles 46, may be provided at each of the apertures 44. Each carcass is suspended from a hook 15 rotatably mounted in a trolley 20 running on the overhead rail. A dog 21 on travelling a chain 19 engages a pin projecting from a trolley, and thus moves it along the rail. A pinion 18, secured to the rotatable shaft of each hook 15, engages a fixed rack or chain 16, so that the hook is rotated. Each scalding compartment comprises at least one electrically driven fan 28, which draws moist air from the upper part of the compartment and circulates this air past a heating element 30 in the passage 40, then, through apertures 29 near the base of the wall 27, into the lower part of the compartment, where the circulating, heated air passes over heated water in a trough 33. This water is heated by an element 34, such as a steam coil or immersion heater, e.g. to generate steam. The circulating, heated air thus picks up steam and/or water vapour before passing upwardly, through spaces 37 between overlapping louvres of a roof-shaped deflector 36, to scald carcasses. Waste, condensed water dripping from the carcasses is directed, by the deflector 36, in an effluent gutter 38 along each side of the compartment. The heating elements may be controlled by means including thermostats 31 and hygrometers 32.
