Filed: 1947-08-27
Abstract: 640,284. Packaging frangible articles &c. WINGFOOT CORPORATION. Aug. 27, 1947, No. 23663. Convention date, Dec. 4, 1946. [Class 94(i)] A method of packaging fruit or other articles comprises enclosing a plurality of articles 9 between two sheets of wrapping material, uniting the surfaces of the sheets in the area surrounding each article, dividing the resulting sheet into smaller sheets each consisting of a plurality of the pocketed articles and then mounting these smaller sheets on frames 18 comprising separate compartments for each of the pocketed articles. The wrapping material is preferably sheets of thermostretchable and heat sealable material such as rubber hydrochloride and is fed from rolls 4, 5 and heated by means of heated rollers 6, 7 before being passed between cupped drums 1, 2. The wrapping material may be stretched into the mating cups 3 in the drums by the articles themselves or by means of plungers or a vacuum applied to the cups. By suitable valve means the vacuum is applied after the cups have been covered with the heated film and is advantageously cut off from the cups in drum 1 just before mating with those in drum 2. The vacuum applied to the cups in drum 2 may be released simultaneously or may be held until the cups reach the bottom of the drum. The drums are wide enough to accommodate three to twenty or more cups and the frames 18 have partitions 19 to accommodate each article in a separate compartment. A number of frames may be stacked on top of one another with a cover on top the whole being secured together by adhesive tape or other means. Specification 640,283 is referred to.

Title: Method of assorting lump material
IPC: B07B1/00
Filed: 1947-09-01
Abstract: 649,033. Sorting solid m a t e r i a 1 s. STRANDSTROM, G. E. Sept. 1, 1947, Nos. 24074 and 24075. Convention dates, Jan. 12, 1945, and May 17, 1945. [Class 117] Lump material of different sizes such as ores, minerals and the like, for instance limestone, the maximum dimension of a lump not differing greatly from its minimum dimension, is assorted according to quality by first separating the material into groups of pieces of different sizes in such manner that twice the smallest dimension of the smallest pieces in each group is at least equal to the smallest dimension of the largest pieces in the same group, and leading each group to its assorting station along a guide channel with side flanges, the distance between which corresponds to the greatest dimension of the largest pieces in this group, thereby forcing the pieces to arrange themselves in the channel one behind the other in the direction of travel except in the case of the smallest pieces of the group two of which at the most can arrange themselves side by side transversely of the channel but not overlying one another. As illustrated, limestone pieces are delivered from a coarse crusher 1 to a duct removing sieve 2 from which they pass to a washing unit 3 and thence to three subsequent shaking sieves 4 of different sizes of mesh where the pieces are separated into four groups of different sizes. These groups slide down into their individual channels R. The last sieve feeds two channels, one with the " thrus " and the other with the " overs." Each channel R feeds four assorting stations 6 at the ends of branch channels 5. Each assorting station 6 comprises assorting means in the form of an endless belt and a separating unit 7 and troughs 8 for conveying the different qualities assorted to collecting silos 9. From each of the separating units 7 a guide trough 8 leads down to each silo 9. The troughs 8 shown in Fig. 3 thus all convey the same quality and the same size group. Thus for five qualities each group has twenty troughs 8 and with four size groups there will be eighty troughs 8, sixteen of which convey the same quality to a silo 9. The material may be caused to move along the channels by reason of the slant thereof, or by shaking or by a combination of both means. In an alternative arrangement, instead of sorting all the qualities at the end of branch channels 5, the grading may be done at different stations along the channel, the number of stations being determined by the number of qualities to be graded, one or more grades being sorted out at each station.

Title: Improved manufacture of hafnium and zirconium compounds
IPC: C01G25/02
Filed: 1924-10-11
Abstract: Phosphates, phosphites, arsenates, arsenites, antimonates, or antimonites of hafnium and zirconium are converted into soluble p compounds by treatment with a medium containing free hydrofluoric acid.  The mixed phosphates may be obtained by treating a hafnium ore with carbon and chlorine or with a flux such as an alkali bisulphate, and adding phosphoric acid to the solution.  The phosphates of hafnium and zirconium are then separated as a precipitate free from compounds of the other metals.  The mixed phosphates are treated with a liquid containing free hydrofluoric acid, for instance a bifluoride solution, and the solution is then poured into an alkaline solution such as ammonia solution to precipitate the oxides, from which the double fluorides may be prepared.  If ammonia has been used as a precipitant it is advisable to make the double ammonium fluorides. The Specification as open to inspection under Sect. 91 (3) (a) refers to the conversion of the compounds of hafnium or zirconium by the process described.  The subject-matter does not appear in the Specification as accepted.

Filed: 1962-06-28
Abstract: 980,519. Secret contact - combination switches. ELECTRONIC SECURITY CORPORATION. June 28, 1962, No. 24813/62. Heading H2B. A secret combination switch comprises a shaft 25 carrying four loosely mounted conducting tumblers 35...38, each tumbler having a toothed periphery with one insulating segment 56 and an annular recess 43 in which is a radially extending web 45 ... 48 respectively. Projecting from the rear of each tumbler is a peg 50 and secured to the shaft is an arm 40 which is engageable with the peg 50 of the rear tumbler 38. Rotation of an indexed operating knob 28 causes arm 40 to pick up the peg 50 of the tumbler 38. Further rotation causes the web 48 of tumbler 38 to pick up peg 50 of tumbler 37. Continued rotation causes the tumblers to be picked up in turn. Rotation of knob 28 is halted by the operator when it reaches its corresponding reference position where the insulating segment 56 of tumbler 35 is engaged by contacts 68, 69 of bus-bars 65, 66. The knob is now rotated in the reverse direction, tumbler 35 being retained in position by the engagement of the contacts 68, 69 with the teeth of the tumbler, until the insulating segment of tumbler 36 is in engagement with its contacts 68, 69. The knob is successively, reversely rotated until the insulating segments of all the tumblers are in engagement with the contacts 68, 69 of bus-bars 65, 66 and thus the circuit through the bus-bars is broken. In order that the combination may be varied the ends of the shaft 25 are of non-circular crosssection and the arm 40 and knob 28 are adjustably mounted on them. In an alternative embodiment (Figs. 8, 9, not shown) a coupling of non-circular cross-section is inserted between the end of the shaft and the knob so that the combination can be varied to a greater extent. The bus-bars 65, 66 are welded or adhesively secured to an insulating lining 60 in the case.
