Patent number: 10087583Abstract: The invention relates to improvements in security elements for use in or on security substrates. In particular the invention is concerned with security elements having public recognition features. The security element includes at least one light transmitting carrier substrate, a first metal layer having substantially metal-free areas defining indicia which are visible in transmitted light, a partial first light scattering layer providing further indicia which are visible in reflected light. The first light scattering layer overlaps the metal free areas in the first metal layer.Type: GrantFiled: October 15, 2008Date of Patent: October 2, 2018Assignee: De La Rue International LimitedInventors: James Peter Snelling, Timothy Edward Berridge

Patent number: 9644383Abstract: A grate cover in combination with a swimming pool being installed in a recess in the top of a sump. The grate is formed of an upper and a lower section. The upper section exhibits four squares or four triangles therein, The upper section has a dome-shaped configuration and has four square or triangular shapes therein, depending on the geometric division therein, each shape has openings therein. The lower section has four trapezoid shapes therein. Each of the shapes of the upper section, whether square or triangular, has a concave surface curvature therein at a transition between the upper and the lower section. Each of the trapezoids of the lower section has two concave surfaces- curvatures therein. One curvature extends in a first direction from the upper section toward an outside edge of grate cover. The other second concave curvature extends in a direction which is normal to the first direction.Type: GrantFiled: August 28, 2014Date of Patent: May 9, 2017Inventor: Peter Snelling

Publication number: 20160176222Abstract: The present invention relates to improvements in security elements for use in or on security substrates. The security element comprises a first light transmitting carrier substrate and at least two regions of material extending substantially parallel to each other along at least a part of the length of the security element. A transverse gap of at least 1 mm lies between the regions of material. The security element further comprises an infill layer which at least partially fills the transverse gap between the regions of material. The infill layer transmits light, such that a layer located on an opposing side of the infill layer from the viewing side is visible through the infill layer when the security element is viewed in transmitted light.Type: ApplicationFiled: July 17, 2014Publication date: June 23, 2016Inventor: James Peter SNELLING

Patent number: 9348070Abstract: The present invention relates to improvements in security devices that can be used in various authenticating or security applications, and in particular to an optically variable security device which can be viewed under low light conditions. The security device comprises a light deflection structure having a first side and a second opposing side. A colorshifting layer is applied to the first side of the light deflection structure and a reflection layer is applied to at least a first region of the second side of the light deflection structure so as to provide a strong reflection in a direction substantially parallel to the incident light source when the direction of the incident light is at an angle away from the normal to the security device. The security device has at least one second region in which the reflection layer is absent, said first and second regions defining indicia.Type: GrantFiled: July 30, 2012Date of Patent: May 24, 2016Assignee: De La Rue International LimitedInventors: Adam Lister, James Peter Snelling

Patent number: 8243356Abstract: The authenticity of a security document, such as a bank note, is verified by use of a security feature arranged in or on the document, which security feature comprises an antenna arranged to receive EM-radiation from an external energy source; a rectifier arranged to receive electric energy from the antenna and convert it into a rectified current; and an electrochromic display arranged to alter its electrochromic state in response to said rectified current. Hence, a security feature able alter its appearance in response to EM-radiation is provided, which comprises a display that can be given a large variety of two dimensional shapes.Type: GrantFiled: April 30, 2008Date of Patent: August 14, 2012Assignee: De la Rue International LimitedInventors: Mats Robertsson, Petronella Norberg, Xin Wang, Staffan Nordlinder, Anna Malmström, Lars-Olov Hennerdal, James Peter Snelling, Philip George Cooper

Patent number: 6569787Abstract: A laminated bullet resistant glazing comprises a plurality of glass and plastic plies arranged in at least two layers including an outer layer and an inner layer. The outer layer extends beyond the inner layer so as to form a step which extends around at least part of the periphery of the glazing. The glazing is reinforced with a band positioned at least partially on the step and having at least first and second longitudinal faces, and in position the first longitudinal face is in contact with the step and the second longitudinal face is in contact with an adjacent portion of the glazing. Application of the band to the step enhances the support strength of the outer layer and enables the manufacture of a bullet resistant glazing having an outer layer reduced in thickness compared to prior bullet resistant glazings.Type: GrantFiled: March 3, 2000Date of Patent: May 27, 2003Assignee: Pilkington Aerospace LimitedInventor: James Peter Snelling
