Shelf Height Adjustment Mechanism

The present invention relates to a height adjustment mechanism (1) adapted to be used in refrigerators (9) having at least one shelf (10), enabling adjusting the height of the shelf (10), and comprising a rectangular prism shaped frame (2) comprising of vertical and horizontal arms, a rectangular shaped shelf bearer (3) movable upwards/downwards inside the frame (2), on which is placed the shelf (10) whose height is to be adjusted, and four threaded shafts (4) mounted on four corners of the frame (2) in perpendicular direction to the horizontal shelf bearer (3) plane, extending between the lower and the upper arms of the frame (2) by freely passing through the holes on the corners of the shelf bearer (3), and provided with helical threads on their outer cylindrical surfaces.


Bubble size control in a two-dimensional fluidized bed using a moving double plate distributor
Koksal, M; Vural, H (1998-03-01)
Pulsating the flow in a fluidized bed by using a moving double plate distributor (MDPD) lo control the bubble size and enhance the fluidization characteristics is a new approach. In this novel design, a second plate Is placed under the existing distributor such that it can make a reciprocating motion generating pulses to the flow field. The frequency and amplitude of the pulsation can be adjusted to break up the large bubbles in the bed. The aim of this study is to investigate the effect of pulsation on the...
Stacking sequence optimization of a composite pressure vessel by genetic algorithm
Kutay, Halil; Kayran, Altan; Department of Aerospace Engineering (2007)
Stacking sequence design is a combinatorial problem when the fiber orientations in each layer are restricted to certain angles. In addition, there often exist many optimal or nearoptimal designs for the stacking sequence of a composite pressure vessel under different loading conditions. Genetic algorithms are quite well suited for finding the optimal designs for such a combinatorial problem. In this thesis, a genetic algorithm code is developed in Matlab, optimizing the stacking sequence of a composite pres...
Stabilized FEM solution of MHD duct flow with conducting cracks in the insulation
Tezer, Münevver; AYDIN, SALİM TUTGUN (2023-05-15)
In this paper, the numerical solution of the fully developed liquid–metal magnetohydrodynamic (MHD) flow is given in a rectangular duct under an external oblique magnetic field with no-slip and insulated walls containing crack regions. The coupled MHD flow equations are transformed first into decoupled convection–diffusion equations in terms of the velocity and induced magnetic field. Thus, we apply the SUPG stabilization in the finite element method (FEM) solution procedure for high values of Hartmann numb...
Edge cracks in a transversely isotropic hollow cylinder
Kadıoğlu, Fevzi Suat (Elsevier BV, 2005-09-01)
The analytical solution for the linear elastic, axisymmetric problem of inner and outer edge cracks in a transversely isotropic infinitely long hollow cylinder is considered. The z = 0 plane on which the crack lies is a plane of symmetry. The loading is uniform crack surface pressure. The mixed boundary value problem is reduced to a singular integral equation where the unknown is the derivative of the crack surface displacement. An asymptotic analysis is done to derive the generalized Cauchy kernel associat...

A shear flexible finite element is formulated for linearly tapered, symmetrically laminated composite beams. The element has three nodes and 18 degrees of freedom. The three-node configuration is obtained from a five-node parent element by constraining the shear angle variation to be linear. The bending in two planes, twisting and stretching are considered. The performance of the element is tested with isotropic and composite materials, constant and variable cross-sections, and straight and curved geome...
