Title: Thermoplastic container end and method and apparatus for inertial spinwelding of thermoplastic container ends
Inventor: FORTUNA VINCENT
IPC: B65D8/22
Filed: 1983-08-01
Abstract: A thermoplastic end is inertially spinwelded onto the paperboard sidewall of a container body, the end having an annular groove 148 for snugly receiving the sidewall 112 and a wall configuration 136, 138, 140, 142 and 144 which minimizes the forces exerted on the bond by liquid contents which would tend to dislodge the end portion. The end portion has strengthening ribs 122 positioned generally within the region of U-shape and additional radial ribs imparting strength and rigidity to the container end. The paperboard sidewall may be internally lined with a layer of thermoplastic material or may be unlined. During spinwelding, a sidewall supporting mandrel having an expandable engaging portion is inserted into the sidewall and subsequently expanded to define a cylindrical surface of a diameter equal to that of the specified internal diameter of the sidewall. A seating member at the end of the sidewall supporting mandrel establishes the depth to which the container end is inserted into the sidewall and is provided with a low-friction member which contacts and aligns the rotating container end with the container side- wall; Figures 4-9 and 13 (not shown). <IMAGE>

Title: Apparatus for determining a change in the composition of a fluid
Inventor: HEEPS BRIAN HAMILTON
IPC: G01N11/16
Filed: 1983-08-03
Abstract: Apparatus for determining a change in the composition of a fluid either liquid or gaseous includes an antenna (16) that is immersed in the fluid. Oscillations are induced into the antenna and then tuned to the natural frequency of the fluid to produce resonance. Any change that then occurs in the composition e.g. density, viscosity, of the fluid will present a different natural frequency at the antenna (16) and hence the tuned frequency of the antenna will no longer produce resonance. Detecting means are coupled to the antenna for sensing resonance and shifts away from resonance arising from a change in the composition of the fluid at the antenna. The apparatus may be used to detect the interface between successive hydrocarbon products pumped along the same pipeline or to detect contaminants in a liquid or gas. The antenna (16) is vibrated generally perpendicular to the fluid flow by either electromagnetic or piezoelectric means (14, 15). Various shapes of antenna are disclosed. <IMAGE>

Title: Diffractive authenticating device
Inventor: GALE MICHAEL THOMAS
IPC: G09F3/00
Filed: 1983-09-13
Abstract: A diffractive coating layer, (202) situated at the interface between a substrate layer (200) and an overcoat layer (208) of the device, is divided into a set of small slightly (a) separated regions (204). This allows a direct bond of the overcoat layer to the substrate layer within the separation areas (206), which direct bond provides a more secure bond than that provided by a bond of the coating layer to the substrate and overcoat layers. <IMAGE>

Title: Canoes
Inventor: MACKERETH GRAHAM JOHN
IPC: B63B35/71
Filed: 1984-01-17
Abstract: A canoe (10) has a seat (13) and two footrests (14). The footrests are formed as buoyancy tanks. The two footrests have lugs hinged together on a pin defined by one end of a cord (32). The other end of the cord can be secured at a cleat 23 accessible to the canoeist. The hinged ends of the lugs are located in a transverse slot (20) in a fore-strengthener (15) and the footrests occupy a uniform width space between the strengthener and the hull of the canoe. By pulling on the cord (32) the footrest position can be easily adjusted by the canoeist. The footrests serve their conventional footrest function, they are adjustable, they serve as buoyancy tanks, and they serve to give lateral support to the strengthener (15). <IMAGE>

Title: Continuous miner
Inventor: WECHNER EDWARD
IPC: E21C27/22
Filed: 1984-05-29
Abstract: A mining machine is disclosed comprising a body 2 mounted on crawler tracks 6. The body can be manoeuvred to face in substantially any direction over the ground on which the machine is disposed. A cutting head comprising cutting drums 40 is mounted at the front of the body 2.

Patent GB-2161602-A (GB)
Title: Examination over a surface
Inventor: HESKETH GRAHAM BERNARD
IPC: G01N29/30
Filed: 1984-07-12
Abstract: In a method for carrying out an examination over a surface of an object, particularly one having a complex shape, a measuring probe (136) is scanned over the surface. For each position of the probe, the co-ordinates of the probe (x,y,z) are measured with respect to predetermined axes, and new co- ordinates (X,Y,Z) are then calculated with respect to axes defined by three points (A,B,C) on the surface. The plane triangle having those points as vertices is subdivided into coplanar elements (1-25), and for each element the corresponding probe measurement is recorded. A visual display (106) may indicate those elements for which probe measurements have been recorded. Further triangles can then be generated and scanned over, each sharing at least one side with a previously scanned triangle. Ultrasonic B-scans may be displayed as grey-scale images on another visual display (108). Coupling between the probe (136) and the surface is taken to be satisfactory when the rear-wall echo is within preset limits. <IMAGE>

Title: An apparatus for crystallising carbon
Inventor: MAYNE LESLIE JAMES
IPC: B01J19/12
Filed: 1984-12-21
Abstract: An apparatus for crystallising carbon to produce diamonds comprises: a hydraulic ram (1) which carries at its end region carbon (3) in solid form; and a chamber (6). The chamber (6) contains a material (13) which is held at a very low temperature, and has an aperture in its lid to receive an end region of the ram (1). The solid carbon (3) is heated using a laser (14) until it has reached a high temperature at which point it is urged into the material (13). The resulting high pressure causes the carbon to crystallise to form diamonds similar to those produced naturally. <IMAGE>

Title: Optical analyser and signal processor
Inventor: DANIEL CAROL DAVID
IPC: G06E3/00
Filed: 1987-04-14
Abstract: An incoherent light beam is analysed by transmitting the beam along a dispersive optical fibre 5 to effect temporal dispersion and then through a diffraction grating 9 to effect spatial dispersion. The light emerging from the diffraction grating then forms a pattern which, with time, changes both its frequency and its position. The arrangement can be used in a filter for an intensity modulated beam. Light emerging from the diffraction grating is focussed at 11 onto a coded mask 14 of transmissive and opaque sections representing a filter function or a signal for correlation. The output from the mask is focussed onto a photo-detector 17. The mask and detector 17 may be omitted, the arrangement then being used to scan a page of information. A two-dimensional and an array of photo-detectors may be employed to effect transforms or filtering. <IMAGE>

Title: A pumping device
Inventor: SIBBALD ALASTAIR
IPC: F04D33/00
Filed: 1987-10-01
Abstract: A pumping device 10 (40, Fig. 4) for fluids comprises a duct 12 (41) along which fluid can flow; a resiliently flexible arm 14 (56) having an upstream end and a downstream end, the arm being free to oscillate transversely with respect to the flow; and magnetic means 20 (59) effective on the arm intermediate said upstream and downstream ends for enabling said transverse oscillation. The downstream end of the arm is free to move transversely with respect to the flow and the upstream end of the arm is so constrained as to be prevented from undergoing transverse movement with respect to the flow. Because of this, the transverse oscillation due to the magnetic means imparts a flagellating action in the arm causing a flow of fluid along the duct. <IMAGE>
