Title: Improvements in mechanical pencils
IPC: B43K24/14
Filed: 1925-04-24
Abstract: 241,808. Alexander, A. E. (Furedy Holding Co., Inc., F.). April 24, 1925. Petted holders. - In a pencil holder of the type provided with lead-feeding mechanism, and in which one of two leads may be projected for use while the other is held retracted in the case, means are provided for effecting a partial rotation of the lead-carriers at a predetermined point in their movement to enable them to be aligned with the aperture in the point, the rotation being effected automatically during the operation of the lead-feeding mechanism. The leads 75, 76, Fig. 1, which may be of similar or different characteristics, are held in the ends of cranked rods 79, 80 the upper ends of which extend into corresponding hollow cylinders 35, 36. The cylinders are formed with oppositely-directed helical slots, the upper portion 40 of each slot being of flat pitch, while the lower portion 41 is of steep pitch. The cylinders are mounted in apertures 18, 19, Fig. 2, formed in a guidemember 11 frictionally held in the upper end of the barrel 10 and formed with longitudinal guide slots 20, 21, into which the upper ends of the rods 79, 80 extend after passing through the helical slots in the cylinders. The guide slots are formed with two offset parts 23, 24, Fig. 4, extending parallel to the axis of the member 11 and approximately corresponding in length and position to the portions 40, 41 of the helical slots in the cylinders, and the parts 23, 24 are connected by an oblique, slot 25. Pinions 45, Figs. 1 and 5, are fixed to the upper ends of the cylinders 35, 36 and are adapted to be rotated together by a ring 50 having teeth engaging with the pinions and frictionally mounted in a cap 52 rotatable on the end of the casing. The pinions are slightly larger than the apertures 18, 19 in order to prevent downward displacement of the cylinders. Rotation of the cap 52 in one direction therefore causes the rapid withdrawal of the lead 76 from the position shown in Fig. 1 due to the engagement of the end of the rod 80 in the steep part of the helical slot in the cylinder 36, and a slight feeding forward of the lead 75 due to the engagement of the rod 79 in the flat portion of the slot in the cylinder 35. When the ends of the rods 79, 80 come to the crossslots 25, they are given a slight rotation to move the cranked end of the rod 79 into, and the end of the rod 80 out of, alignment with the aperture in the detachable tip 15. Further rotation of the cap in the same direction then causes rapid advance of the lead 75 and slow retraction of the lead 76. Spare leads may be carried in apertures 30 formed in the member 11. The end of the cap 52 may be adapted to hold an eraser 87, and a covering-cap 70 may also be provided, the eraser or cap serving to close the ends of the receptacles 30 and to prevent upward movement of the cylinders 35, 36.

April 14, 1936, No. 10710. Convention date, May 27, 1935. [Class 41] Alloys of alkaline earth metals with heavy metals are obtained by electrolysis of a fused electrolyte consisting of the oxide of the alkaline earth metal dissolved in a mixture of the chloride and the fluoride using an anode of carbon and a molten cathode of the heavy metal such as lead zinc or copper. The oxide may be replaced by the carbonate, oxalate, acetate or other compound forming the oxide on heating. The flux may consist of a 60 parts of calcium chloride to 40 parts of calcium fluoride corresponding to formation of calcium chlorofluoride, but percentages of calcium fluoride between 10 and 60 may also be employed. The alloy formed may be refined electrolytically as anode using a cooled iron cathode on which a tube of the alkaline earth metal, e.g. calcium is deposited ; the same electrolyte is suitable in this stage. Alternatively in the refining the metal may be deposited into a top cathode layer of molten aluminium or magnesium to form an alloy with these metals.

Polymerization is effected at temperatures of about 70 DEG  to 150 DEG C. and in the liquid phase, and diluents may be used.ALSO:Calcium, barium and strontium chelates are prepared by customary methods from organic carbonyl compounds containing a hydroxy group (including enolic hydroxy) attached to a b -carbon atom.  The chelating agents may be esters of b -carboxylic acids of the type R1COCHRCOOR1 wherein R is hydrogen, alkyl or aryl and the R1S represent alkyl or aryl ; beta-diketones of the type RCOCHR1COR wherein R is alkyl or aryl and R1 represents hydrogen, alkyl or aryl ; o-hydroxy phenyl carbonyl compounds of the type <FORM:0851271/IV(b)/1> wherein R and R1 represent hydrogen, alkyl or alkoxy and beta-keto acid amides of the type RCO,CHR1,CONR2R3 wherein R is alkyl or aryl, R1 is hydrogen or alkyl and R2 and R3 represent hydrogen, alkyl radicals or aryl radicals which may be alkyl- or alkoxy-substituted.  Numerous chelating agents of each class are specified.  In Examples (1) strontium acetate is reacted with sodium ethyl aceto acetate ; (2) butyl aceto acetate is reacted with calcium acetate in aqueous ammonia ; (3) calcium acetate is reacted with a solution of aceto acet-p-phenetide in aqueous NaOH. The chelates are used as polymerisation catalysts (see Group IV(a)).

Mouldings of expanded cellular ebonite are made by incorporating into a rubber composition a blowing agent which reacts above the vulcanizing temperature vulcanizing the composition in a mould at a temperature such that the blowing agent does not react, removing the moulded component from the mould and expanding the moulded component by heating uniformity over its surface area. The expanded moulding is then heated further to convert the rubber to ebonite. The blowing step is preferably performed in a heated bed of fluidized particles. Preferably the rubber composition, which may be natural or synthetic is moulded at 140‹ C., heated to expand for 3-5 minutes at 180-200‹ C. and heated for 2-3 hours at 150‹ C. to complete the conversion to ebonite. The vulcanized rubber moulding may be stored before or after foaming for subsequent conversion to ebonite.
