Title: Reduced friction formwork for a concrete slab
Inventor: FABIO PARODI
IPC: E04G19/00
Filed: 2013-06-11
Abstract: Disclosed is a support element for a reduced friction formwork for a concrete slab using a layered liner sheet that compresses over a period of time. The support element for use as a component of a formwork for producing a concrete slab to be supported on a surface of at least one load bearing member, the support element includes a layer of active material which compresses under load. A first surface of the support element is attached to a backing sheet and a second surface of the support element opposite the first surface can form a support surface of the formwork onto which concrete is poured to form the concrete slab. The active material is chosen such that the load supported by the active material reduces gradually from an original value of 100% when the concrete is poured to less than 40% of its original value after 10 days as the concrete cures and the load is gradually transferred onto the at least one load bearing member. The backing sheet has a coefficient of friction less than 0.4 when placed in contact with another backing sheet of the same kind and includes thermal insulation. The layer of active material is sandwiched between two backing sheets. The thickness of the active material is in the range from 10 mm to 50 mm and includes an flexible enclosed void of a fluid or air or gas.

Patent NZ-756905-A (NZ)
Title: Comfort and safety linen system
Inventor: SIEBUHR JASON
IPC: A47G9/10
Filed: 2018-02-14
Abstract: Provided herein is a bed linen system formed from a one-piece panel that includes slits separating a bed sheet portion from a blanket portion and integral gussets that envelop the corners of a mattress. The gussets include a parabolic curve, a long edge and a short edge wherein the long edge is integral to a side edge of the bed sheet and the short edge is attached to a headboard or a footboard side edge. The slits work in conjunction with the gussets to redirect tension from pulling force applied to the blanket towards the center axis of the mattress, thereby making it more difficult to remove the system from the mattress by a user, while allowing the user to ventilate the foot area during use. Minimizing the attachment points to create the gussets provides resistance to tearing. The system is advantageous in that it provides a bed linen system that avoids opportunity for use as a self-harm device, affords comfort and care, and requires minimum effort in linen changes for patients who have difficulty with movement and/or are impaired.

Title: Crewing system for sailing vessel
IPC: B63H9/00
Filed: 1996-03-15
Abstract: The crewing of a sailing vessel never allowed the crew member a static position. This innovative crewing system consists of a vertical shaft 1, fixed at the transverse centre of the boat, connected to which a structure 2 rotates, supporting, on opposite sides of the shaft, mast 3 and crew member. This lever system is actuated by the force of the wind F applied to the sail 4 which alters and defines the position of the mast [at a distance from the shaft which can be refined, a] and, consequently, that of the crew member, depending on wind direction. The crew member thus remains in a seat 5 which has a translational movement X (around the shaft) and allows radial movement Y (approaching or moving away from the shaft), this being effected and checked 6 by the crew member as a function of wind force. Steering is transmitted from a wheel 7 (coupled to the seat) to the rudder or rudders 8 via cables 9. Angular adjustment Z of the sail does not interfere with the lever system, given the travel of the sheet 10 which passes via the axis thereof. <IMAGE>

IPC: H01Q3/26
Filed: 1994-01-04
Abstract: FIELD: antenna engineering. SUBSTANCE: size and quantity of array antennas depend on size and shape of areas to be irradiated and quantity of beams depends on number of beam-generation circuits feeding the array. All antennas operate at the same amplitude level; direction and shape of beams depend on phase setting. Active phased-out transmitting antenna array has many antennas arranged in hexagonal manner. Each antenna has horn capable of radiating every signal of two orthogonal polarizations. Horn is excited by multipole band filter designed to pass signals at frequency within specified band and to suppress signals of other frequencies. Filter is coupled with dielectric air cavity installed on substrate. Dielectric air cavity has solid high-efficiency push-pull integrated amplifiers exciting orthogonal microwave signals by means of probes in combination with amplifiers arranged so that they excite cavity when they are spaced 180 deg apart. Beam shape and direction and signal amplitude of all antennas are maintained at equal level by means of phase shifters and attenuator installed on substrate and connected to amplifiers placed inside cavity. EFFECT: provision for simultaneous generation of several independent beams for irradiating desired areas without irradiating other areas of space.
