Title: Improvements in or relating to bottle or like capping machines
IPC: B67B3/02
Filed: 1948-05-03
Abstract: 651,487. Bottle capping machines. SCOTTS ENGINEERING (NEWPORT), Ltd., and BURDIN, N. V. May 3, 1948, No. 12028. [Class 125(ii)] In a machine for capping bottles or the like, the load required for the capping operation is applied to the capping head by a resilient member, which is adapted to be loaded gradually, and to be released when required, to provide the said load, thus avoiding undue variation in the output from the machine driving mechanism. In the form shown, a horizontal driven cam shaft 4 carries cams 5 and 6 which engage followers 7 and 8. Cam 5 is profiled so that it lifts the follower 7 gradually, compressing a spring 10 from its lower end. During this operation, the upper end of the spring is held stationary by a link 17 connected to the cap 18 which abuts the said upper end, the link being connected by a lever 13 to the follower 8 which, at this time, is bearing on a concentric portion of the cam 6. A beam 20 is mounted so that one end bears on the cap 18 and the other on the capping head 22 which is of the form described in Specification 651,486. At the appropriate moment the follower 8 engages a stepped down portion of the cam 6 and, through lever 13 and link 17, releases the upper end of the spring, which then exerts its accumulated energy on the beam 20 to effect the capping operation.

Title: Improvements in or relating to the Manufacture of Hollow Ware.
Inventor: SNYDER GEORGE COCHRAN
IPC: B27D1/08
Filed: 1918-07-30
Abstract: 118,110. Snyder, G. C. July 23, 1917, [Convention date]. Machines and apparatus for making tubs, pails, &c. In a process for making barrels, tubs, pails, &c., two strips of material are simultaneously wound in spiral form so as to produce two hollow elements tapered in opposite directions. In making a barrel, a strip of material is drawn from a roll mounted on a rod 50, Figs. 1 and 2, and after it has been slit longitudinally by cutters 56, 67, the two portions are wound on the adjacent ends of a pair of mandrels 23 driven from a shaft 29, the ends of the mandrels abutting against each other during the commencement of the winding operation. When a few turns have been wound, the mandrels are gradually moved apart by screws 39 driven from the shaft 29, thus causing successive convolutions of the strips to overlap so as to produce two hollow tapered elements. When the wound portions have reached the desired length, the rotation of the screws 30 is; stopped by disconnecting clutches 44, 45, and the cutters 56, 67 are moved out of action by levers 57, 66 operated by a sliding cam 82 moved by a lever 72, which is turned by a circular projection 70 on one of the mandrels 23. A few turns of unslit material are then wound round the centre of the barrel. When the central portion of the barrel has reached the desired diameter, a roller 106 moves a stop 105, thus allowing a spring-pressed knife 100 to descend and sever the material transversely. Clutches 46, 47 are then thrown into gear to separate further the mandrels 23, so that the finished barrel body falls into a shoot 132. During winding, the outside of the barrel is engaged by spring- pressed wipers 125. Cam-actuated pins 87 mounted on the mandrels 23 are arranged to embed themselves in the strips of material so as to hold the first windings in their correct positions while the mandrels are being separated to form the tapered portions of the barrel. The shape of the barrels may be altered by varying the rate of separation of the mandrels. Adhesives &c. or a powder adapted to act as a binding-material when the barrel is subsequently heated are spread upon the material by jets 131. Coating-material may be applied to the interior of the barrel by a pipe 98. Tubs and pails may be made in the same manner as barrels, except that the cutters 56, 67 are retained in action through the entire winding operation. In a simpler form of machine adapted for making barrel-shaped containers, mandrels 135. Fig. 11, are moved apart by arms 144 operated by a shaft 141 formed with right- and left-handed screw-threads. The arms 144 are thrown out of action when the container has attained the desired length. The mandrels are moved farther apart, to release the finished article, by handoperated levers 149, 152.

Abstract: 1,033,039. Bonded-fibre fabrics. E. I. DU PONT DE NEMOURS & CO. March 24,1965 [April 10, 1964], No. 12439/65. Heading D1R. A flexifilamentary sheet is bonded by light compression between two surfaces of which one is of heat-conducting material and maintained at a temperature equal to or greater than the upper limit of the melting range of the film-fibrils, and the other is of a flexible poor heat conductor, cooling the sheet while still restrained, and then if desired repeating the process with the sheet faces reversed. "Film-fibrils" are longitudinally extended fibrous elements in the form of a ribbon of thickness less than four microns. A "flexifilament" is a strand comprising an integral three-dimensional network of film-fibrils. As shown the sheet 5 passes around idler roll 3c and is pressed on to the internally heated drum 1 by the endless belt 2 of felt. The drum 1 may be of steel and is hot enough to bring the surface of the sheet to a temperature equal to or slightly less than the upper limit of the melting range of the film-fibrils of the sheet. The belt may be preheated by the roll 9 and the heated plate 10, but is cooler than the drum, so that the back of the sheet remains at a lower temperature than the face. The belt 2 and sheet 5 pass from the drum 1 to a cooling roll 4 to cool the sheet under restraint. The flexifilaments are preferably of polyethylene or copolymers in which at least 85% of the recurring units are ethylene units. The other monomor can be proplylene or 1-butene. The strands may contain waxes, dyes, pigments, antioxidants, delustrants, antistatic agents, reinforcing particles, adhesive promoters, bactericides, dye promoters, removable particles, ion-exchange materials or ultraviolet-light stabilizers. Glass fibres may also be present. The initial sheet may be formed by electrostatic laying of the flexifiiamentary strands, and may then be completed by rolls or embossed.

Title: Improvements in or relating to the production of gas mixtures rich in hydrogen
IPC: C01B3/22
Filed: 1936-05-01
Abstract: In a process for production of gases rich in hydrogen by the partial combustion of methane with oxygen, two coke shafts 1, 2 are connected at their lower hot ends by a passage 7, the methane containing gas being introduced through a pipe 3, and passed alternately down each shaft.  The methane is heated in shaft 2, and passes with oxygen supplied from nozzle 6 through passage 7 into shaft 1 where it is cooled, and the gases from the conversion leave by outlet 8, the gas being then passed in the opposite direction through the shafts 1, 2. A catalyst such as calcium oxide, iron ore, or alkalized blast furnace coke may be used, and, to increase the hydrogen content, water vapour may be added. a portion of the carbon monoxide being converted into carbon dioxide.  To prevent undue deposition of soot due to <PICT:0458557/III/1> hydrocarbons in the gases, the coke and slag may be extracted by conveyer worms 10 which are cooled by steam from a pipe 15, a branch from which leads to the coke container 14.

In one embodiment, as shown, the member 101  is moved by altering the distance between the tip of probe 106 from the member 101, the probe 106 having an externally screw threaded portion 117 which engages with an internally screw threaded collar 116. A transparent scale plate 122 carried by brackets 120, 121, in conjunction with a line 126 on a barrel portion 125 of the probe 106 allows the transverse distance moved through to be determined. The distance between the probes 104, 106 may be adjusted to accommodate different wheel or tyre sizes. Two coplaner mirrors 202, 203 may be provided which are adjusted to a vertical plane by leg 207, pivotal probes being mounted on the mirror assembly so as to define vehicle abutment surfaces and thereby effect correct orientation of the mirror assembly. In an alternative embodiment, the member is movable between the two positions by rotation about a pivotal mounting which is fixed in relation . to the probe tips, a scale being provided to enable the angle turned through to be determined. The mirror may be double sided and provided with a horizontal sight tube having hair lines along its length to align with plumb bobs draped over corresponding parts of the vehicle in order to position the mirror perpendicularly to the horizontal axis of the vehicle. In an alternative mirror construction, two vertical and coplaner mirrors are employed which are mounted to pivot about a vertical axis to allow the desired orientation thereof to be attained. The various mirror and gauge embodiments may be interchanged.
