Patent GB-365888-A (GB)
Abstract: 365,888. Match - making machines. BADISCHE MASCHINENFABRIK & EISENGIESSEREI VORM. G. SEBOLD UND SEBOLD & NEFF, 3, Seboldstrasse, Durlach, Baden, Germany. April 7, 1931, No. 10184. Convention date, Sept. 23, 1930. [Class 50.] The fixed guides l, m for the match-carrying elements a are interrupted at the dipping table by horizontally displaceable guides k. The dipping table b is raised between guides d, e to effect contact with the matches and just before contact is also moved in the same direction and at the same speed by links g together with the guides d, e which slide along rods f. Cross rods h, i connect the respective guides d, e at each side of the machine. The guides k having a slot through which passes a guiding screw p slide on extensions n, o of the machine, being coupled to the guides d, e by lugs k<1> engaging with rod i. The grooves in the guides k are curved immediately in front of and behind the dipping table so as to incline the elements a in these positions, the increased distance between the ends of adjacent matches allowing the table to pass in and out between the match rows. A fixed bar q secured to cross rods r, s supports the elements midway between their ends and a moving guide t secured to the rods h, i is disposed above the bar q.

IPC: C07C17/02
Abstract: 366,348. Dichlorethylene ; tetrachlorethane. CONSORTIUM FUR ELEKTROCHEMISCHE INDUSTRIE GES., 20, Zielstattstrasse, Munich, Germany. April 9, 1931, No. 10457. Convention date, May 9, 1930. [Class 2 (iii).] Dichlorethylene is obtained by bringing acetylene and chlorine in substantial absence of water vapour into contact wth cuprous and/or cupric chloride at an elevated temperature. The copper chloride may form a coating in a base of metallic copper or may be deposited on pumice, carborundum, or other support. The reaction may be carried out at temperatures above 150‹ C. and substantially below 400‹ C. According to one example, chlorine and acetylene in the ratio of 2: 1 are passed through a copper tube filled with copper Raschig rings through which chlorine has previously been passed at 160‹ C., the reaction temperature being maintained in the range 200-240‹ C. by cooling. Dichlorethylene consisting chiefly of the low-boiling isomer is formed, together with some tetrachlorethane. Other examples in which proportions of 1 : 1 and of 15 : 13 of acetylene and chlorine respectively are employed are also given.

A. ; 2, Duncan Street, Millburn, New Jersey, U.S.A.) Dec. 5, 1929, No. 37313. Convention date, Jan 2. [Classes 39 (i) and 40 (v).] A screen-grid valve with its associated input and output circuits is so arranged and connected that there is substantially no coupling between these circuits due to parts being common to both circuits and entirely separate paths are provided for the charging currents for the capacity constituted by the screening grid and the anode. Similar arrangements may be made for the screen-grid to control grid capacity and one lead to the screening grid may be taken through one wall of the valve and another lead to the screening grid be taken through the opposite wall. The input and output circuits are arranged in separate compartments in a screening box with the valve projecting through an aperture (Fig. 4, not shown). High-frequency chokes are provided in all supply leads. A similar arrangement for the valve used as a detector is employed and in the output a low-pass filter is provided. Fig. 2 shows an arrangement in which coupling due to the charging current to the capacities formed by the screening grid and the grid and anode respectively is eliminated. Fig. 3 shows an arrangement in which, in addition, the coupling due to a lead to the filament common to the input and output is obviated. The invention is particularly applicable to short-wave signalling.

Title: Method and apparatus for securing a rigid end piece upon one end of a thermoplastic tubular element and tubular containers thus obtained
Filed: 1956-12-13
Abstract: 815,448. Cutting containers from thermoplastic tube. TUBOPLAST, S. A. Dec. 13, 1956 [Dec. 19, 1955; Dec. 7, 1956], No. 38122/56. Class 87(2). [Also in Groups XVII, XXVIII, XXXII and XL(b)] A machine, Fig. 9, for making tubular containers comprises feed rollers 21, 22 that seize a thermoplastic tube 13 issuing from an extruding machine and deliver it along a support 12 to a severing device 14 and shaping ring 16. A vertical shoot 15, containing rigid end-pieces 2 formed with an annular groove having a restricted mouth, is arranged so that an end piece 2 drops down one at a time into the path of the tubing 13, whereupon the moving tube enters the groove in the end-piece and presses the endpiece against a spring biased heating member 17. The end of the tube then melts to fill the groove after which it may be cooled by means such as an air jet, where after severing means 14 is automatically operated and the resulting article falls into a shoot 18. A cam 58, rotating with the roller 21, causes a rod 53 to move the heating member 17 with the tube 13 during a working stroke and to make a quikc return stroke. The severing means comprises a double edged blade so that after it has performed a cutting operation by moving in one direction it can cut off the next length of tubing by moving in the opposite direction. A control and timing device (not shown) employs solenoids to oscillate a rocking lever coupled to the cutting means 14, there being a dash-pot arrangement in the mechanism for ensuring a quick cutting stroke and a damped finish to the stroke. In a modified form, Fig. 10, a support 73 carries a source of light 74 and a photo-cell 75 on either side of the path of travel of the tube 13. The cell 75 is connected through an amplifier 76 to the solenoids of the severing mechanism. A heating solenoid 71, connected to a source 72 of high frequency current, is also carried by the support 73, the support 73 being adjustable along the tube axis by screw means 77, 78. When the end of a plastic tube intersects the light beam the photo-cell 75 actuates the severing mechanism, the tube 13 having been heated by the high frequency currents to cause the end of the tube to melt and fill the groove as described above.
