Title: Production of porous metal fluoride pellets
IPC: B01J20/00
Filed: 1972-09-08
Abstract: 1363198 Metal fluoride bodies UNITED STATES ATOMIC ENERGY COMMISSION 8 Sept 1972 [7 Oct 1971] 41769/72 Heading C1A A stable and porous metal fluoride body is made by (a) forming from a mixture of sinterable metal fluoride powder essentially non- reactive with gaseous fluorinating agents and water, an agglomerate containing from about 0À5 to 25% water and (b) contacting the agglomerate with a mixture of a non-reactive gas and a gaseous fluorinating agent to convert substantially all of the water therein to volatile products by localized exothermic reaction of said agent and water, the temperature of contacting and the concentration of said agent being controlled to limit the heat generated by fluorination to values effecting bonding of said agglomerate at the sites occupied by said water. The agglomerate may be contacted with the mixture of non-reactive gas and gaseous fluorinating agent in two successive operations the first being conducted at a lower temperature, e.g. 80 to 100 F., and with a lower concentration, e.g. 0À5 to 10 volume per cent fluorine, balance argon, than the second which may be carried out at a temperature below the temperature effecting generalized sintering of the agglomerate using a fluorine content up to 100 volume per cent. A volatilizable lubricant, e.g. a stearate, may be incorporated in the agglomerate and the resultant metal fluoride body may be in the form of individual pellets comprising a comparatively hard, moderately reactive exterior and a more reactive (higher surface area) interior characterized by a high sorption capacity.

Title: An endless conveyor installation with selection control for delivery of goods at selected receiving stations
IPC: B65G47/48
Filed: 1959-12-10
Abstract: 897,583. Endless conveyers for delivering goods at selected positions. DURKOPPWERKE A.G. Dec. 10, 1959 [Jan. 9, 1959], No. 41998/59. Class 78 (1). A conveyer for delivering goods in transport boxes T at selected positions arranged along its length on both sides of the conveyer comprises a pair of endless chains 51 between which are mounted by their diagonallyopposite corners rectangular carriages F, the arrangement being such that the carriages remain horizontal in upper and lower runs of the chains and when passing over suitable guides (not shown) from one run to the other. Each carriage carries rollers running on rail tracks 55 and a platform 59 which supports a transport bar T and is supported on the carriage by two longitudinally-extending pins 66 on opposite sides of the platform engaging in opentopped pivot bearings 60 on the carriage. A selector device comprising two sets of push-buttons 72 is also mounted on the rear of each carriage, each button 72 when depressed causing downward projection of a contact member 71, and the arrangement being such that whenever one button in each set is depressed it releases any previouslydepressed button. At each of a number of positions along the conveyer there is a sensing device comprising a pair of microswitches 73, 74 connected electrically in series. When a carriage reaches the selected delivery position the two contact members 71 on the carriage simultaneously operate the microswitches 73, 74 at that station to complete a circuit to a solenoid 76 which moves a shaft 78 to project a roller 79 into the path of a stirrupshaped rail 67, mounted on and depending from the platform 59. A drop pawl 80 engages the end of the shaft 78 to prevent it from being returned by a spring 77. As the carriage arrives opposite the delivery position rollers 70 on one side of the platform 59 pass under a retaining rail 82 secured to the edge of a receiving table 83 at the same side of the conveyer, while at the same time the roller 79 engages the inclined portion 67<SP>1</SP> of the stirrup 67 to raise the platform. Since the platform is held down at the delivery side by the rail 82 the platform is tilted, as a result of which stop. members 84 on the carriage, normally projecting through slots in the platform to retain the box T, are made flush with the surface of the platform, so that the box T slides by gravity on to the receiving table 83. After delivery a release lever 86 on the carriage engages and pivots the drop catch 80 to allow spring 77 to return the roller 79 out of the path of the stirrups 67 of following carriers. Rollers 70 are provided on both sides of the platform so that by the above arrangement boxes T are delivered to the delivery tables of successive receiving stations on opposite sides of the conveyer, the rail 82 being arranged to hold down the side of the platform 59 adjacent the receiving table.

Title: Scales
IPC: G01G19/414
Filed: 1964-10-14
Abstract: 1,088,058. Digital weighing apparatus. HOBART MANUFACTURING CO. Oct. 14, 1964 [Oct. 15, 1963], No. 42015/64. Heading G4H. In a weighing machine weight placed on platter 21, Fig. 2, causes movement of a coded scale 36 having marks in cyclic decimal code, each digit being represented in cyclic binary form, the marks being sensed by photo-cells 50. The scale is illuminated from behind by lamp 40 and an image of a small section is projected by lens 42 on to a mask 45 having an array of slits, one for each photo-cell 50. There are fourteen photo-cells each sensing one of the tracks A-N, Fig. 4, of Scale 36. The tracks are grouped in three fours and a pair, representing four decimal digits. The decimal digits are represented in cyclic form and each digit is represented in cyclic binary form. The most significant digit can be zero, 1 or 2 so that a pair of binary, digits suffice to represent it. The range of the machine is 25 pounds. The E and G tracks of the tenths digit are extended below zero and above 25 lb. to give an indication that the machine is outside its working range. The presence of E and G signals is used to prevent operation of the apparatus. Signals from the photocells are applied to five four-layer diodes whichenergize corresponding relays. Contacts of the relays are connected in decoding network in which the first three digits of each decimal digit are converted to a, value 0-5 and this member or its nines complement is taken according to the value of the fourth digit and the highest order decimal digits. (In the cyclic decimal code alternate decades use the ten digits in reversed order so that, for two digits, if the high digit is even the nine complement of the digit is taken, thus 16 becomes 13 whereas 26 remains 26.) The groups are read out in succession each as a mark on one of ten leads to a computer or printer. There are means normally preventing operation of the apparatus. unless the weight exceeds a certain minimum, e.g. 1/10th of a pound. The M track (the tens of pounds) is cut away from zero to 1/10th of a pound so that, below this minimum, neither the M or N relay is energized. This is normally used to prevent operation of the apparatus but it can be overridden by a manual control. The A and C tracks are used to indicate that the scale has come to rest. Means are provided to sense when either of the A or C relays has droppedout. The A and C tracks have coded areas in mutually exclusive positions so-that one or the other or neither is operative. The corresponding relays are arranged to discharge through capacitors so that they drop-out after a small delay. Contacts of the A and C relays are connected in series with a detector relay coil which remains energized as long as the A and C relays are alternately energized in quick succession due to the speed of movement of the scale. As the scale slows down one of the relays A and C releases and after a short delay the detector relay responds to allow operation of the apparatus.
