IPC: F16L33/213
Filed: 1944-02-24
Abstract: 575,057. Pipe couplings. CHIFFEY, E. Feb. 24, 1944, No. 3457. [Class 99 (i)] A coupling for hose or soft metal pipes comprises a rigid tubular member 6, which is fitted over the end of the pipe and has secured thereon a hollow support 9 which is subsequently expanded to grip the pipe, a strengthening conical member 16 being then forced in to expand the support 9 still further.

Title: Improved fuel compositions
Inventor: JACKSON ROBERT GLOVER
IPC: C10L1/10
Filed: 1957-02-01
Abstract: A lead-scavenging and anti-knock fuel comprises gasoline containing not more than 2 theories of halohydrocarbon scavenger in which is dissolved or dispersed (a) not less than 5 theories with respect to the lead of certain boron compounds, and (b) not less than 0.5 theories with respect to the lead of sulphur and/or phosphorous compounds.  The boron compound is defined as any boron compound soluble or dispersable in the base fuel other than boronic or borinic acids of the general formula R-B(OH)2 and <FORM:0829635/III/1> respectively, wherein R is a cyclic radical with a cyclic carbon attached directly to the boron, or their anhydrides or salts. Examples of the boron compounds are boric acid, alkali metal and alkaline earth metal salts of oxy-acids of boron; trialkyl esters, acid esters, cyclic and dicyclic esters of boric acid, especially ethyl 2-methyl pentane 2,4 diolborate, alkyl boronic and dialkyl borinic acids and their esters, particularly the cyclic esters formed from alkyl boronic acids with 6 to 10 carbon atoms and alkane diols with 2 to 8 carbon atoms alkanolamine esters of boronic and borinic acids, borazoles and boric acid polyesters. Suitable sulphur compounds added to the fuel preferably in the proportions of 10-15 theories, for example, oil-soluble sulphur compounds of sweetened Middle East crude oils contain thiophene and its derivatives, such as dialkyl thiophene, e.g. 2 methyl thiophene, 3 ethylthiophene, 2,4 dimethylthiophene or benzthiophene.  The phosphorus compounds which may be added to the fuel in the ratio of 0.5 to 1.5 theories in preference to the sulphur compounds or as a mixture with the sulphur compounds are oilsoluble organic esters of oxyacids and thioacids of phosphorus, such as ortho-, pyro-, or metaphosphoric acids, and phosphorous or hypophosphorous acid, the alkyl-phosphonic and alkyl phosphinic acids and their thioanalogues, for example, tri-methyl phosphates and phosphites, triphenyl orthophosphate, tricresylthiophosphate, dicresyl propyl phosphonate.  The gasoline portion of the fuel which may be a straight-run, catalytically or thermally reformed, or catalytically or thermally cracked gasoline suitable for use in spark-ignited internal combustion engines and can contain benzene, toluene, alcohol or ethers should not contain more than 0.2 theories of halohydrocarbon lead scavengers, for example ethylene dichloride and ethylene dibromide, and is preferably free from such compounds.  Lead containing anti-knock compounds such as tetraethyl lead, ethyl trimethyl lead, diethyl dimethyl lead, triethyl methyl lead and tetramethyl lead are present in the fuel in the proportions, for tetra ethyl lead from 0.5 to 5 cc. per Imperial gallon.  Specifications 722,537, 722,538, 794,380, 818,047, 818,727 and 829,634 also are referred to.

Title: A new or improved fabric adapted for production on twist lace machines
IPC: D04C5/02
Filed: 1921-01-31
Abstract: 178,596. Coombes, W., and Pare, F. W. Jan. 31, 1921. Lace.-One or more weft threads d are laid within a shed formed from the warp threads b ... b<111>, c ... c<111> and bobbin threads a of a twist lace machine in such a manner that at the places where the wefts are locked in, the warps exert equal and opposite forces on the bobbin threads, thereby preventing distortion of the latter and reducing the tendencv of the fabric to unrove. The warps b ... b<111> are carried by one fully threaded bar or the equivalent number of partially-threaded bars and the warps c ... c<111> are carried by a similar bar or equivalent. The two bars are shogged simultaneously in opposite directions when the carriages are in the back combs. The weft d is laid in when the carriages are at the front, and a second weft e may be laid in when the carriages are at the back but is not locked in as is the weft d. In a modified method of working two pairs of warp bars or their equivalent are used one pair to lock in a front weft when the carriages are at the front and the other pair to look in a back weft when the carriages are at the back. Additional patterning or like threads may be inserted.

Title: A method for the manufacture of paraformaldehyde in a crapechip form
Filed: 1959-02-04
Abstract: Paraformaldehyde is manufactured in a "crape-chip" form by casting a hot aqueous solution of formaldehyde, having a concentration of 60-95% by weight, over the surface of a body maintained at a temperature below an absolute temperature Tl, defined by the equation T1 = 83,5 + 3,35F, in which F is the percentage concentration by weight of formaldehyde, so that the solution is formed into a uniform thin layer; scraping the thin layer of partially solidified material before the surface portion is completely solidified, thus converting the material into a crape-chip form; and drying it on a penetrable bed carrying the material by passing a dry inert gas through the bed so that it penetrates and dries the material.  The inert gas may be, for example, air or nitrogen and it is preferred to use it at an elevated temperature.

Title: Improvements relating to valveless lubricating pumps
IPC: F16N13/10
Filed: 1927-02-14
Abstract: 275,494. Steinwandt, J. Feb. 14, 1927. Reciprocating - cylinder pumps; camactuated pumps. - A valveless pump for supplying oil to a number of lubricating points in succession comprises a casing a in which works a piston c operated by a cam g carried by the driving-shaft u. The upper end of the piston is bored to accommodate a plunger q which shares the motion of the cylinder until a nose q<2>on the plunger is arrested by contact with one of a series of adjustable stops r. This arrangement permits the amount of oil to be supplied to the lubricating points to be regulated, as on the arrest of the plunger oil is sucked into the space c<2> as one of a series of radial ducts in the cylinder is in alignment with one of a series of ducts m in the casing in communication with an oil reservoir by way of a duct p<1>. At the bottom of its stroke, the piston c is rotated through a predetermined angle by a driving-pin s and during the upward stroke, the charge of oil in the space c<2> is delivered to one of the lubricating points by way of one of a series of ducts m, p, with which the radial ducts in the cylinder is now in alignment. The drive of the pin s is effected by its engagement with one of a series of recesses i in a polygonal part e of the piston, this polygonal part co-operating with a flange on the cam to lock the piston against rotation during its stroke. The polygonal part is provided with a similar part, but having a lost motion relative thereto controlled by a pin. This arrangement secures the resumption of the proper sequence of operations when the motion of the pump is reversed.
