Gallery wrap. Gallery wrap is a method of stretching an artist's canvas so that the canvas wraps around the sides of the stretcher bar or strainer bars and is secured to the back of the wooden frame.

Structure
The frame is usually 1.25" (approx. 4 cm) thick. As a result, the hardware (staples or tacks) used to secure the canvas are not visible. The sides of the canvas are prepared and primed in the same manner as the face or front. They may then be painted a solid color (usually white) or painted to continue the image appearing on the face. This method of stretching and preparing a canvas allows for a frameless presentation of the finished painting or photograph. In some competitions it is considered "framed" and ready to hang.

Terminology
In canvas printing, the term "gallery wrap" refers to an image that appears on the sides of the frame as well as the front. The image on the sides is either a continuation or a reflection of the main image, or an otherwise fabricated element such as a solid color or colors derived from the adjacent image.

Gallery wrap is a very popular way to display art. However, because the edges of the canvas are wrapped over the thick bars, approximately two inches of the image (top, bottom, and sides) are not visible from the front. If the subject of an image or painting is sized and positioned correctly, the image will not be negatively affected. However, in some situations photo editing techniques are employed to fabricate additional image/material or to mirror existing content  on the wrapped edges. Solid colours can also be used on the wrapped edges.

Gallery wrap production can be digitally automated with a Photoshop plugin or raster graphics editor.

Gallery wrap versus non-gallery wrap
Gallery wrap is a method of displaying art wrapped over thick wooden bars so that there are no visible fasteners (such as staples or tacks). This method of stretching and preparing a canvas allows for a frame-less presentation of the finished painting.

In contrast, a non-gallery wrap canvas is usually intended to be framed before presentation. 
The stretcher bars are often thinner, and the canvas can be secured at the sides with staples or tacks as the frame will hide them. 
However, thin stretcher bars can be found "gallery wrapped" as a hangable work without a frame.

Paul Pietzschke. Paul Pietzschke, or Paul Pietzschke NautiChem, is a German corporation that produces sealants, coatings and lubricants for shipbuilding. Its main office is in Norderstedt, North Germany. It was founded by Paul Pietzschke in 1889 in Hamburg, Germany, as a chemical and technology company.

Products 

From the beginning, the Paul Pietzschke Company has produced and marketed a line of elastic sealants, coatings and lubricants for the commercial shipbuilding industry. In 1962 it developed the WKT Synthetic Sealing Compound, the first fully synthetic sealant for the yacht and shipbuilding industry. The company's products are sold under the registered trademark NautiChem.

History 

Paul Pietzschke was founded by its namesake in 1889 in Hamburg, Germany. Its first trademark was registered in the German imperial patent office on February 24, 1898, under the name Paul Pietzschke. Its logo showed the letter “P” and a newt tied up in chains, with its mouth closed with a padlock, indicating that Pietzschke products protected from the harsh effects of rough sea water, even under the water line. In 1998 Mr. Paul Peter Pietzschke, from the third generation of the family-owned enterprise, transferred the company to Mr. Ralf Beckedorf. NautiChem was introduced as the company’s new trademark in 2001 and since then is used in the company’s current name, Paul Pietzschke NautiChem.

Gully emptier. A gully emptier (colloquially: "gully sucker") is a type of specialized tank truck with suction gear which can suck wastewater and mud and sludge out of hollows such as the hollows below drain grids in street gutters and carry it to a suitable disposal point. It needs to be able to suck out and pump through into its tank any road grit and miscellaneous solids that have entered the hollow.

Some have a means of squeezing the water from its load, and letting that water into the drain or keeping it for high pressure cleaning of drain pipes.

Differences from a vacuum truck
A vehicle which is purely a vacuum truck has a long wide flexible hose without the big solid nozzle with controls on.

Gully emptiers are often outfitted with devices to separate the liquid content of its tank from solid matter, allowing the liquids to run to storm drain.  Since this is not done with cesspool content, cesspool emptiers have no need for such separative capability.

Sometimes a gully emptier has a flexible hose without solid nozzle like on a cesspool emptier.

Opel Super 6. The Opel Super 6 is an executive car which was built by the German car manufacturer Opel between 1937 and late 1938. The car was equipped with a 2.5-litre straight-six engine and had a top speed of . It was available in three different versions: a 4-door sedan, a 2-door coupé, and a 2-door cabriolet. A small number of custom-bodied cars were also made by various coachbuilders such as  and Gläser.

The  produces  at 3500 rpm. In total, 46,453 Opel Super Six were built in the two years it was available.

An interesting detail was the windscreen wiper drive which received its power via a mechanical linkage from the camshaft, a solution which Opel continued to use in post-World War II Rekord models until 1957.

Hexamethyldisilane. Hexamethyldisilane (TMS2) is the organosilicon compound with the formula Si2(CH3)6, abbreviated  Si2Me6.  It is a colourless liquid, soluble in organic solvents.

Synthesis and reactions
Hexamethyldisilane can be produced by Wurtz-like coupling of trimethylsilyl chloride in the presence of a reducing agent such as potassium graphite:

With an excess of the reductant, the alkali metal silyl derivative is produced:

The Si-Si bond in hexamethyldisilane is cleaved by strong nucleophiles and electrophiles. Alkyl lithium compounds react as follows:
Si2Me6  +  RLi  →   RSiMe3  +  LiSiMe3

Iodine gives trimethylsilyl iodide.
Me3Si−SiMe3  +  I2  →   2 SiMe3I

Fish tape. A fish tape (also called a draw wire, draw tape, or an electricians snake) is a tool used by electricians to route new wiring through walls and electrical conduit.

Made of a narrow band of spring steel, by careful manipulation, the tape can be guided through confined spaces such as wall cavities or conduits in many countries. The goal is to push toward an area where guide string has been dropped inside the confined space and to pull it through, so the guide string can then be used to pull through various types of wiring, such as phone wire, network cables or speaker wire. Fish tape is designed to pull through guide string only. Using it to directly pull the target wire can damage or warp the fish tape.

Design 

Fish tapes are usually stored coiled on a plastic reel. Because of this, they have a natural curvature and it is this curvature that allows them to be guided. By manipulating the reel, the end of the tape can be directed slightly. The tape is rigid enough that it can then be pushed in the direction in which it is pointing. In this way it can be easily guided through an empty wall cavity. Thermal insulation, firestops, pipes, HVAC ducts, electrical conduits, and other obstructions make use of a fish tape more challenging.

The "tape" can be made from many different materials including steel, fiberglass, and nylon. The tape usually has a special end ranging from a hook or loop to a specialized fastener device to allow the user to attach the tape to the guide string (or a very light cable) before pulling.

Invention and patent
Keith Leroy Wilson of Colorado Springs, Colorado, owner of the Electrical Construction Co, founded in 1947; invented the Fish Tape Snagger.  Wilson filed the original patent on 29 Mar 1960 and Patent # 3,035,817 was awarded on 22 May 1962 by the US Patent Office.

Double use 

Occasionally, two fish tapes are used from opposite ends of the wall. Because they each have a hooked end, one fish tape is capable of catching the other, and the one tape can then be pulled back, carrying the second tape out with it. Electricians sometimes attach a battery and a doorbell or buzzer to two fish tapes so that when the ends of the tapes make contact with each other (within the wall), the bell rings.

HMAS Shepparton (A 03). HMAS Shepparton (A 03) is a Paluma-class survey motor launch of the Royal Australian Navy (RAN).

Design and construction

The Paluma-class vessels have a full load displacement of 320 tonnes. They are  long overall and  long between perpendiculars, have a beam of , and a draught of . Propulsion machinery consists of two General Motors Detroit Diesel 12V-92T engines, which supply  to the two propeller shafts. Each vessel has a top speed of , a maximum sustainable speed of  (which gives a maximum range of ), and an endurance of 14 days.

The sensor suite of a Paluma-class launch consists of a JRC JMA-3710-6 navigational radar, an ELAC LAZ 72 side-scan mapping sonar, and a Skipper 113 hull-mounted scanning sonar. The vessels are unarmed. The standard ship's company consists of three officers and eleven sailors, although another four personnel can be accommodated. The catamarans were originally painted white, but were repainted naval grey in 2002.

Shepparton was laid down at Eglo Engineering's shipyard in Port Adelaide, South Australia on 21 September 1988, launched on 5 December 1989, and commissioned into the RAN on 24 January 1990. The ship was named for the city of Shepparton, Victoria.

Operational history
In January 2011, Shepparton was one of three RAN vessels deployed to survey Moreton Bay and the Brisbane River for submerged debris as part of Operation Queensland Flood Assist, the Australian Defence Force response to the 2010–11 Queensland floods.

In October 2013, Shepparton participated in the International Fleet Review 2013 in Sydney.

On 16 June 2023, HMAS Shepparton and  were decommissioned at , with the acceleration of the Defence Strategic Review released in May 2023.

National Railway Equipment. National Railway Equipment Company  is an American railroad equipment rebuilding, leasing, and manufacturing company, headquartered in Mt. Vernon, Illinois.  NREC sells new and rebuilt locomotives to railroad companies worldwide, with an emphasis on the North American market.

N-ViroMotive Series

NRE's flagship locomotive product is dubbed the N-ViroMotive and is targeted at providing light duty road switcher engines with increased efficiency and decreased air and noise pollution.  These locomotives are specifically targeted for yards and other urban environments where noise & exhaust from idling locomotives can become a nuisance.  They also fill a market segment for light duty locomotives now largely abandoned by the major builders, GE & Electro-Motive, which have not listed such locomotives in their catalog for nearly 20 years.

N-ViroMotives are newly built as opposed to rebuilt with donor parts.  They use a low hood design with up to three diesel generator sets (gensets) that supply power to the traction motors.  The current gensets use a  Cummins diesel engine and can be easily swapped in and out for repair or overhaul work.  The gensets are computer-controlled to switch on and off according to the demands of hauling the load.  Trucks are of the EMD standard Blomberg B design.

As of 2009, NREC has sold upwards of 210 N-ViroMotives to many different railroads, including the U.S. Army, with the largest order of 60 being delivered to the Union Pacific which plans to use them in the smog conscious L.A. area.

Aeromarine PG-1. The Aeromarine PG-1 was an American single-seat pursuit (fighter) and ground attack (PG) biplane developed by the Engineering Division of the United States Army and manufactured by the Aeromarine Plane and Motor Co.

Development and design
The PG-1 was intended to fulfill both ground strafing and aerial defense roles, the contract for construction was won by Aeromarine in May 1921.

Armed with a single 0.5 in (12.7 mm) machine gun as well as a 37 mm Baldwin cannon firing through the propeller hub; the cockpit had  armour. The wings were dissimilar, with a wide-chord upper wing with ailerons, and a closely spaced narrow-chord lower plane with dihedral that placed the tips close to the upper wing. The upper wing was mounted close to the top of the fuselage with a cut-away forward section to accommodate the cockpit, and attached to the lower plane via V-type struts.

Power was to have been provided by the eight-cylinder, water-cooled  Wright K-2 engine but the first two prototypes were fitted with  Packard 1A-1116 units due to delays in clearing the K-2 for flight testing. A third prototype was also built and testing was eventually carried out using both the K-2 and Packard 1A-1237 at McCook Field. Prototype aircraft suffered disappointing performance, high levels of vibration and poor visibility. The aircraft had a tendency to spin when stalled. Development was abandoned in 1922.
