Patent GB-964348-A (GB)
Title: Dewaxing and deoiling process
IPC: C10G73/06
Filed: 1961-08-14
Abstract: Oil and wax are separated from each other by conducting a mixture of the oil and wax in flowable form under the surface of a liquid solvent for the oil, said solvent being at a temperature below the solidification temperature of the wax in the mixture, as measured in the solvent, dispersing the mixture into the solvent, for example by spraying, so as to emerge therein as particles or droplets of size 5-100 microns, and after a sufficient interval of time for the wax to solidify and the oil to dissolve, separating the wax particles from the solvent and oil, for example by filtering.  The solvent may thereafter be recovered from the oil.  The initial wax-oil mixture may first be heated to above the melting temperature of the wax.  Any conventional solvent for deoiling or dewaxing may be used, methyl ethyl ketone with either toluene or benzene being preferred.

Title: Improvements in or relating to Razor Blades
Inventor: WATSON HUGH ROBERT
IPC: B05D7/14
Filed: 1966-06-30
Abstract: 1,175,527. Steel/synthetic resin laminate; razor blades. WILKINSON SWORD Ltd. 7 Feb., 1967 [30 June, 1966], No. 29322/66. Headings B4B and B5N. [Also in Division B2] A razor blade has on and/or adjacent its cutting edge a coating of, or containing, a polymer and/or copolymer of tetra-fluorothi-irane. The copolymer may be of tetra-fluorothi-irane with tetra-fluoro-ethylene. The polymer and/or copolymer may be deposited, e.g. as a powder, dispersion or solution, by dipping or spraying, on the blade which is thereafter heated to cause the polymer and/or copolymer to adhere thereto. The dispersion may be formed in a solvent, after which the solvent is replaced by a more volatile solvent having a boiling point below 150‹ C. A liquid having a boiling point of volatile solvent not less than 150‹ C. may be applied to the blade before or after the dispersion is deposited. The coated blade is heated in a reducing or inert atmosphere or in vacuo to a temperature above the melting point of the polymer. The coating may be applied by frictional transfer from a stropping disc having a surface of, or loaded with, the polymer, by direct bonding, e.g. by adhesion or hot rolling of a thin foil of polymer, or by polymerization of the monomer in situ or by gaseous deposition of the polymer. A subbing layer of a polymer or vinyltriethoxysilane or lauric acid may be interposed between the metal surface and the polymer coating, or the metal surface may be pretreated or rendered porous, e.g. by etching, metal plating by spraying, evaporation or by electrolysis, or by heating in a gaseous atmosphere. The blade may be of stainless or carbon steel.

Title: Liquid dispensing apparatus
IPC: B67D7/74
Filed: 1973-06-21
Abstract: 1438164 Dispensing liquids LLEWELLYN LEWIS Ltd 16 May 1974 [21 June 1973] 29573/73 Heading A4T Blending dispensing apparatus e.g. for petrol comprises flowmeters 3, 4 for measuring the flow of two respective constituents, a stepping motor (not shown) for simultaneously operating valves controlling flow of the constituents so that rotation of the motor in respective direction increases or decreases the proportion of one constituent, and a control circuit for actuating the motor in accordance with processed pulses from the meters 3, 4. If, for example, a blend of 75%:25% high octane: low octane petrol is to be dispensed, the number 25 corresponding to the low octane percentage is set into a memory 1. With the valves correctly set, the high octane meter 3 will produce 3 pulses for every one from the low octane meter 4, and a total of four pulses per low octane pulse will be summed by an OR gate 7 and fed to a logic circuit 9. The input from the gate 7 is multiplied by the number from the memory 1 to produce an output of 100 pulses per low octane pulse, which is divided by 100 by a divider 11 and fed to a logic circuit 12, having two outputs 13, 14 for respectively stepping the motor and determining the direction of movement. If the pulse frequency output of the divider 11 is greater than the pulse output of the meter 4, indicating an excess proportion of high octane petrol, the motor will be actuated to increase the low octane proportion, whereas a lesser output will actuate the motor in the opposite direction to increase the high octane proportion. Identical outputs will result in stepping of the motor in alternate directions as the pulses are received, to maintain a uniform overall blend ratio. The output of the gate 7 also actuates a counter 15 for operating displays at the dispensing point and a central station, indicating the quantity dispensed, and governs a line 25 for terminating dispensing if a maximum allowed volume is reached. It is also fed through a settable divider 16, set according to whether the petrol is priced e.g. by the gallon or the litre, to a second logic circuit 19 having a memory 2 into which the unit price is set, the circuit producing an output for controlling a total price display. Lines 23 may further be provided to enable the incorporation of means for setting the apparatus to dispense petrol to a given total price or for the inclusion of a note validator.
