Ashby's Mill. Ashby's Mill, often referred to as Brixton Windmill, is a restored grade II* listed tower mill at Brixton in the London Borough of Lambeth. The mill was in Surrey when built and has been preserved.

History

Ashby's Mill was built in 1816 and worked by wind until 1862, when the business was transferred to a watermill at Mitcham on the River Wandle. The sails were removed in 1864 and the windmill was relegated to use as a store. In 1902, the lease on the watermill expired and a steam engine was installed in the windmill. This was later replaced by a gas engine. The windmill was worked by engine until 1934, and supplied wholemeal flour to West End hotels and restaurants.

After the war, there were proposals to demolish the mill and build a block of flats. The proposal was rejected and it was decided to conserve the mill, which was restored in 1964 by London County Council. New sails were fitted, and machinery from a derelict windmill at Burgh le Marsh, Lincolnshire installed to replace that which had been removed. The work was done by Thompson's, the Alford millwrights. Following restoration, the mill was opened to the public at Easter 1968. The mill passed to Lambeth Council in 1971 and remains in their ownership. Further restoration was carried out in 1978 and 1983, but the windmill had been placed on the Buildings at Risk Register in 1995.

The Friends of Windmill Gardens had been formed in April 2003 with the aim of restoring the windmill and surrounding area as a public amenity. In September 2004, an archaeological dig was organised, with assistance from the Museum of London Archaeology Service. A £25,000 grant was given by Lambeth Borough Council towards repairs to the mill and gardens. A £2,000,000 restoration plan has been put together with assistance from the Horniman Museum and the Society for the Protection of Ancient Buildings. An application for a grant from the Heritage Lottery Fund was submitted. The Heritage Lottery Fund granted £397,700 towards the restoration. Lambeth Council and the Friends of Windmill Gardens also contributed towards the restoration of the mill, which cost £581,000. The restored mill was officially opened to the public on 2 May 2011 by Chuka Umunna, MP for Streatham.

Description

Ashby's Mill is a four-storey brick tower mill with a boat shaped cap. It had two Patent sails and two Common sails. The cap was winded by a hand wheel, no fantail being fitted. The cast iron windshaft is the only remaining original piece of machinery. The mill is  diameter at the base and  to the curb, and  high overall.

USNS Henry Eckford. USNS Henry Eckford (T-AO-192) was a Henry J. Kaiser-class fleet replenishment oiler of the United States Navy. She was never completed.

Construction
Henry Eckford, the sixth Henry J. Kaiser-class ship, was laid down by the Pennsylvania Shipbuilding Company in Chester, Pennsylvania, on 22 January 1987. Her construction encountered numerous problems. Although she was launched on 22 July 1989, her construction contract with Pennsylvania Shipbuilding was cancelled on 31 August 1989. Along with her unfinished sister ship USNS Benjamin Isherwood (T-AO-191), the incomplete Henry Eckford was towed to the Philadelphia Naval Shipyard in Philadelphia on 27 October 1989 for lay-up.

A new contract was awarded on 16 November 1989 to the Tampa Shipbuilding Company of Tampa, Florida, to complete Henry Eckford, and she was towed from Philadelphia to Tampa. However, construction problems continued, and that contract also was canceled, on 15 August 1993, when the ship was 84 percent complete. Cost overruns had run into the millions of U.S. dollars.

Reserve
The Navy decided that completion of Henry Eckford as an oiler was no longer necessary, and considered converting her into an ammunition ship, but the conversion was found to be cost-prohibitive. Instead, the nearly complete Henry Eckford was turned over to the Maritime Administration and towed up the James River in Virginia, where she remained in reserve in the National Defense Reserve Fleet as part of the United States Navy's James River Reserve Fleet at Lee Hall, Virginia. She was struck from the Navy List on 10 November 1997, and her title was transferred to the Maritime Administration on 2 February 1998. She and Benjamin Isherwood were the only units of the 18-ship Henry J. Kaiser class not to be completed.

Scrapping
On 19 July 2011, Henry Eckford departed for Brownsville, Texas, to be recycled by International Shipbreaking Limited.

Bresler–Pister yield criterion. The Bresler–Pister yield criterion is a function that was originally devised to predict the strength of concrete under multiaxial stress states.  This yield criterion is an extension of the Drucker–Prager yield criterion and can be expressed on terms of the stress invariants as

where  is the first invariant of the Cauchy stress,  is the second invariant of the deviatoric part of the Cauchy stress, and  are material constants.

Yield criteria of this form have also been used for polypropylene and polymeric foams.

The parameters  have to be chosen with care for reasonably shaped yield surfaces.  If  is the yield stress in uniaxial compression,  is the yield stress in uniaxial tension, and  is the yield stress in biaxial compression, the parameters can be expressed as

Alternative forms of the Bresler-Pister yield criterion 
In terms of the equivalent stress () and the mean stress (), the Bresler–Pister yield criterion can be written as

The Etse-Willam form of the Bresler–Pister yield criterion for concrete can be expressed as

where  is the yield stress in uniaxial compression and  is the yield stress in uniaxial tension.

The GAZT yield criterion for plastic collapse of foams also has a form similar to the Bresler–Pister yield criterion and can be expressed as

where  is the density of the foam and  is the density of the matrix material.

Hurt Wood Mill, Ewhurst. Hurt Wood Mill is a grade II* listed tower mill at Ewhurst, Surrey, England, which has been converted to residential use.

History

Hurt Wood Mill was built in 1845, replacing a post mill that had been blown down. The post mill was standing in 1648. The mill worked by wind until c1885 and the  sails and fantail were removed shortly afterwards. The mill house was converted at some point, with two new sails being fitted in 1914. In 1937 four new sails and two new stocks were fitted by Neve's, the Heathfield millwrights.

Description

Hurt Wood Mill is a four storey brick tower mill with an ogee cap. It had four Patent sails carried on a cast iron windshaft. The cap was winded by a fantail. The clasp arm Brake Wheel is wooden. When the mill was a working mill, it had sails that rotated anticlockwise, but those fitted in 1937 would have rotated clockwise had they been a working set.

Philipp Forchheimer. Philipp Forchheimer (7 August 1852 – 2 October 1933) was an Austrian engineer, a pioneer in the field of civil engineering and practical hydraulics, who also contributed to the archaeological study of Byzantine water supply systems. He was professor in Istanbul, Aachen, and Graz.

Forchheimer introduced mathematical methodology to the study of hydraulics, thus establishing a scientific basis for the field. He graduated as engineer from the Technische Hochschule Zürich in 1873, received his doctoral degree from the University of Tübingen, and completed habilitation at the Technische Hochschule Aachen. He was the rector of the Graz University of Technology until 1897. In addition to his teaching, he worked as a consultant for underground construction projects. He made proposals for the construction of a tunnel under the English Channel.

In 1891, he took up a parallel appointment in Constantinople at the Ottoman School of Engineering, which he successfully re-organised in 1914. His work in Turkey led to a study of the Byzantine cisterns with the archaeologist Josef Strzygowski. In 1897 or 1898, he spent a month researching aqueduct systems at the Austrian excavations in Ephesus.

Modification to Darcy's Law 
Forchheimer proposed a modification to Darcy's Law, describing fluid flow through packed beds in 1901. This also had a significant influence on the development of the Ergun equation.

where:

 is the pressure drop across the bed,
 is the viscosity of the fluid,
 permeability (const.),
 is the (area-averaged) velocity of the fluid,
 is an empirical constant,
 is the density of the fluid.

A more general expression of the friction factor follows from Forchheimers modification:

where  is the Reynolds number and C is a constant.
