Title: Improvements in and relating to high-speed planing machines
IPC: B23D7/00
Filed: 1937-02-12
Abstract: 490,371. Hydraulic transmission of power. LANGE, A., (trading as LANGE & GEILEN MASCHINENFABRIK). Feb. 12, 1937, No. 4196. [Class 69 (ii)] [Also in Group XXII] A hydraulic machine tool such as a high-speed planing-machine has a main pump for operating the table and a subsidiary variable delivery pump which may operate the cross feed of the tool and also has its suction pipe connected to the delivery of the main pump, so that it may assist the reversal of the table. The main pump P driven through gearing m from a motor M draws from a reservoir A and delivers through pipe 11 to a valve V. A valve connection 28 leading from the pipe 11 has check valves 29, 291 which prevent direct flow from the line 11 into line 28. The pipe 11 is also connected to the suction side of the auxiliary variable delivery pump 23 which is driven directly by motor M and delivers through pipe 21 to reversing valve R connected by pipes 19, 20 to the ends of valve V. The pump delivery is controlled by tilting the pump casing by means of a cam 24 and lever mechanism 17, 25. The table is operated by a cylinder 1 connected by pipes 12, 13 to the valve V. Dogs D, D<1> on the piston rod 3 act through a lever 30 to shift the reversing valve. The ends of the reversing valve may be connected to a distributer T for lubricating the machine. The stem 5 of the valve V operates a link 27 to rotate the cam 24 and operate the table feed through ratchet mechanism 26, 26a. In operation during the stroke of the main piston to the right the parts are in the positions shown, the pipe 11 connected to pipe 12 through the valve V, and the pump 23 in its minimum delivery position also connected through valve R lines 19 and 28 and check valve 29 to the pipe 12. Exhaust passes through lines 13, 15, 16. Near the end of the stroke, the dog D shifts the valve R so that lines 21 and 20 are connected and valve V is moved to right, liquid from the front of piston 9 being directed through pipe 19 to the lubrication system. Shifting of the valve V directs fluid from pipe 11 to line 13 to return the table and also directs the subsidiary pump output through line 20 and valve 29 to pipe 11. Movement of the valve stem 5 to the right meanwhile causes the cam 24 first to raise the pump 23 to its maximum delivery position and then to restore it to minimum delivery position which is reached when reversal is completed. The variation in the delivery of the subsidiary pump at the end of the stroke causes the table velocity curve, Fig. 2, instead of falling abruptly from v<1> to v<2> to follow the rounded line shown in Fig. 2.

Abstract: 1427631 Two part coupling AKZONA Inc 30 Jan 1974 [1 Feb 1973] 04369/74 Heading H2E To prevent mating of misaligned or inappropriate connector members, each is made hermaphroditic, with shrouded male contacts and protruding female contacts. Annular shells 10, 12 of mating connector members, with 10 fitting into 12, carry identical cylindrical inserts 32, each shell comprising three stacked insulating plates 34, 35, 36 with aligned contact apertures. Rear plate 34 is retained by flange 37 behind shell shoulder 38, and by sleeve 40 gripped in in the shell by rib 41. Sleeve 40 carries an elastomeric body 43 with cable gripping apertures. Male and female contacts 45, 46 are carried in the plate apertures, with retainer members 52 surrounding the necked parts 48 of the contacts and trapped in the apertures of middle plate 35. Male contacts 45 lie behind the face of insert projection 54 while female contacts 46 project beyond projection 54, the set forward and set back parts 54, 56 of the face of plate 36 joining along diametral plane 58. On mating the connector members with correct alignment, female contacts on one member engage male contacts in the other and vice versa. Shell 10 carries loose ring 22, retained by annulus 20 captive in groove 18 in the shell and a groove in ring 22, and on mating ring 22 is rotated to engage in internal helical channels the equispaced pins 24 on shell 12. Rotation of ring 22 until pins 24 slip behind spring detents 31 compresses elastomeric block 60 round the female contacts. Block 60 both retains plate 36 and exerts force after mating to maintain pressure between pins 24 and ring 22. The leading edge of shell 10 makes on full engagement a moisture-tight seal against elastomeric ring 84 in shell 12. Other designs (not shown) employ unequal numbers of male and female contacts in one insert and complementary numbers in the other non-identical insert, the dividing surface on plate 36 being no longer diametral, and optionally a cylindrical surface rather than a plane. Each connector member can then mate only with its complement. Axial keys (62-66, Fig. 2, not shown) on the periphery of shell 10, fitting in keyways (72-76, Fig. 3, not shown) inside shell 12, may be provided. Shell 12 is shown with flange (80) having holes (82) for panel mounting (Fig. 3, not shown).

Abstract: 1,101,171. Transferring processes; pictures. F. G. EDWARDS. 2 Feb., 1965 [3 Feb., 1964], No. 4545/65. Headings B6C and B6X. A process for transferring an image 10, Fig. 2, from a paper backing 14 to another backing comprises the steps of coating the obverse side of the image with a water emulsion of an acrylic polymer, drying the coating 15, soaking the paper backing and coated image in water, peeling the wet paper backing from the coated image, coating the reverse side of the coated image with said water emulsion of an acrylic polymer, and applying the coated image to the other backing with the coating 24, Fig. 8, on the reverse side still wet and in contact with the other backing which may be canvas or board such as 25. It is useful to precede the application of the coating 15 by spraying the image 10 with a solution of acrylic ester resin which forms a film 13 and thereby prevents bleeding or running of the image when the water emulsion is applied. Several applications of the coating 15 may be effected and desired body thickness of this material may be ensured by sticking sheets of compatible material to the initial coating. The transferred image may be built-up with further coats of emulsion over the coating 15 or the latter may be removed, leaving the image as it was at the beginning or after the film 13 was applied.
Patent GB-496348-A (GB)
Title: Manufacture of tetrachlorethylene
IPC: C07C17/00
Filed: 1938-02-14
Abstract: Tetrachlorethylene is produced by passing over a hot inorganic catalyst a mixture of acetylene, ethylene, or a chlorhydrocarbon having 2 carbon atoms and not more than 4 chlorine atoms, and hexachlorethane or a fully chlorinated paraffin containing more chlorine than hexachlorethane such as fully chlorinated propane or butane.  A suitable mixture may be made by treating tetrachlorethylene with chlorine to convert a part of it into hexachlorethane, and then passing this mixture together with acetylene, ethylene or the chlorhydrocarbon containing not more than 4 carbon atoms over the catalyst.  The reaction temperature may be 200-400 DEG  C., and the catalyst may be broken glass or porcelain, wood charcoal, bone charcoal, active carbon or silica gel.  The catalyst may be impregnated with a substance known to promote splitting off of hydrogen chloride such as cupric chloride.  Examples describe the production of tetrachlorethylene from mixtures of hexachlorethane with trichlorethylene, tetrachlorethane, and dichlorethylene, respectively and also from a chlorination product of tetrachlorethylene together with acetylene.  In the last case, if excess of acetylene is used some di- and tri-chlorethylene are also produced.
