Title: Improvements in or relating to methods and apparatus for the production of heterofilaments and heteroyarns
Inventor: LODGE REGINALD MONTAGUE
IPC: D01F8/04
Filed: 1962-07-31
Abstract: Composite or heterofilaments and heteroyarns are produced by separately metering into a spinneret assembly comprising a cover, housing and spinneret plate at least two synthetic polymers in a viscous liquid state, i.e. either viscous melts or viscous solutions. The polymers allowed to meet and form a liquid interface or interfaces and are forced, after forming the liquid interface or interfaces through a filtering medium contained within the spinneret assembly and are extruded through the orifices in the spinneret plate to form filaments which are subsequently drawn to orient them.  The polymers may be metered into the assembly in a molten state and after forming the liquid interface or interfaces, and being forced through the filtering medium contained within the assembly may be extruded to form filaments which are solidified by a transverse blast of air. The liquid interface(s) formed by the polymers within the spinneret assembly and the orifices within the spinneret plate may be arranged to be parallel and in the same vertical plane and the volumetric flow rates of the polymers may be adjusted to produce heterofilaments (composite filaments) in which the polymers are in side-by-side relationship.  The interfaces and some or all of the spinneret plate orifices may be otherwise disposed with respect to each other so that some or all of the filaments produced are homofilaments consisting wholly of each of the polymers.  The polymers may be polyamides.  At least one of the polymers may be polyhexamethylene adipamide.  One of the polymers may be an interpolymer of polyhexamethylene adipamide and polyepsilon caprolactam, e.g. in the proportions 80 : 20.  At least one of the polymers may contain a delustrant such as titanium dioxide or a coloured pigment.  At least one of the polymers when in filamentary form may be an elastomer or a potential elastomer. At least one of the polymers in filamentary form may be potentially adhesive under conditions in which at least one other component in filamentary form is non-adhesive.  One component in filamentary form may have a greater shrinkage capacity than the other polymer(s) in filamentary form.  When one of the polymer components can be rendered adhesive by heating, the heterofilaments may be used to form non-woven fabrics, the filaments being bonded together at their cross-over points by heating them.  The heterofilament may consist of a polyhexamethylene adipamide component and a polyepsilon caprolactam component, the latter being rendered adhesive by heating the filament to temperatures at which the other polymer is still non-adhesive.

Title: Geophysical prospecting apparatus
Inventor: MCLAUGHLIN GEORGE HARRISON
IPC: G01V3/08
Filed: 1955-10-18
Abstract: 825,046. Geophysical prospecting. NUCOM Ltd. Oct. 18, 1955, No. 29740/55. Drawings to Specification. Class 37. Geophysical prospecting apparatus comprises means responsive to naturally occurring time transients of the earth's magnetic field having a frequency range in the range from 1 to approximately 20,000 cycles per second to provide a signal representing the intensity of such transients. In the case of an electrically conducting ore body the time transients are stated to induce eddy current in the body which reduce the magnetic field in the body but which increase the magnetic field externally of the body. In the case of magnetically permeable bodies the magnetic lines of force produced by the time transients are concentrated in the body and are reduced outside the body. As described the apparatus comprises a search coil which can be tuned to a number of frequencies in the above range and the output of which is applied to an indicating instrument via an amplifier. The apparatus enables the variation in the direction or amplitude of the magnetic field at a number of points adjacent the body to be formed and by graphically plotting the angle or amplitude against distance the location of the body and whether it is of electrically conducting or magnetically permeable material can be found. Readings at different frequencies are taken since it is stated that good conducting bodies such as massive sulphides will concentrate magnetic fields of all frequencies above a few cycles per second whereas poor conductors such as disseminated sulphides will only concentrate fields above a few hundred cycles per second; wet faults and clay are stated to only effect high-frequency fields and these differences and the use of appropriate frequencies enables the different bodies to be located. To eliminate thermal noise two identical tuned circuits connected in opposition can be used each being connected through a suitable amplifier to a single indicator.

Title: Improvements in and relating to water closets
IPC: E03D5/04
Filed: 1927-11-07
Abstract: 306,639. Pitt, S. Nov. 7, 1927. Actuating-mechanism.-A water closet comprises a basin 1, Fig. 1, pivotally supported in a pedestal 1<a> eccentric to its central axis, means being provided whereby the raising of the seat may tilt the basin and open the flushing valve, and its subsequent lowering permits the return of the basin and valve to their initial positions. A flexible member 15 is connected at its opposite ends to the seat and to a pulley 9 on a spindle 7, means being provided so that, when desired, the seat may be moved without effecting motion of the flexible member. Normally, however, the lifting of the seat turns the pulley to tilt the basin. Simultaneously a pin 11 is moved to contact with a shoulder 17<a> on a tumbler weight 17 and throw it over to turn a spindle 20 to open a flushing valve 21. Water then passes through a pipe 25a to a tank 26, Fig. 5, having an outlet pipe 28 delivering into the basin. When the seat is lowered, the tension on the member 15 is relieved, and the eccentricity of the basin causes its return to normal position; the pulley 9 simultaneously returns and the pin 11 engages one end of an adjustable pin 18 and returns the tumbler weight 17 to close the flushing valve. A plate 10 loosely mounted on the pulley 9 has a slot 10<d>, Fig. 6. in which the pin 11 works, an arm 10<b> carrying a basin counterbalance weight 14, and a slot 10<c> loosely engaging a fixed pin.
