Lampin Corporation. Lampin Corporation is a Massachusetts-based component manufacturer and assembler of right angle gear drives, spur gear, and mechanical assemblies, serving the aerospace, medical, optical, semiconductor, food processing, and high-tech industries. Lampin offers design review, supply chain, and inventory management services. Lampin is 100 percent employee-owned.

History
Harold Fairbanks founded the company as the Laminated Pinion Gear Company in 1964. The company was initially headquartered in Ashland, Massachusetts, a town in the Blackstone Valley. In the 1970s, Harold Bushnell purchased the company and moved it to Uxbridge, its headquarters.

On November 23, 1982, Scott Rossiter purchased the company, renaming it the Lampin Corporation. In 1990, Lampin acquired MITRPAK, a line of spiral bevel gear drives, from Johnson & Bassett, a Worcester, Massachusetts company founded in 1870.

Lampin continued to expand, and in 2001, Rossiter elected to sell 30% of the company to the employees through the employee stock ownership plan (ESOP). In 2006, Rossiter sold all the shares to the ESOP, making the company 100 percent employee-owned. In 2013, Lampin received a $74,100 matching grant from the state of Massachusetts to create jobs and train thirty new employees.

Current corporate directors are Floranne R. Reagan, Michael S. Shaw, and Donald J. Romine.

In January 2022, John Biagioni was appointed president following Robin LeClaire's retirement, who will remain on Lampin's board.

Acquisitions
In March 2016, Lampin acquired the precision component manufacturer Howard Precision Products of Framingham, Massachusetts. The company was formerly known as the E. Howard Watch & Clock Company, founded in Massachusetts in 1851. All employees of Howard were offered positions at Lampin and were to be moved to Lampin's facilities in Uxbridge.

Gribovsky G-28. The Gribovsky G-28 (, VVS designation TI-28) was an advanced trainer for trainee fighter pilots, built in the USSR just before the German invasion in 1941. It satisfied VVS testing but changing priorities led to the abandonment of production plans.

Design and development
The TI in the VVS name for the G-28 indicated its function as a Trenirovochni Istrebitel or Fighter Trainer. After basic training a prospective fighter pilot could gain experience of the characteristics of a quite fast, manoeuvrable, single seat, enclosed cockpit aircraft, fitted with guns or bombs. It was, like all earlier Gribovsky aircraft, almost entirely of wooden construction.

Its cantilever low wing had two wooden spars and was plywood skinned.  The ailerons were fabric covered duralumin frames and the inboard, pneumatically activated flaps were also duralumin.  In plan the wing was strongly tapered, mostly on the trailing edge, carefully faired into the fuselage at the wing roots and ending in elliptical tips.

The G-28 was powered by a  MV-6 six cylinder inverted in-line engine, driving a two blade variable pitch propeller.  The engine was on a steel tube mounting and enclosed in a light-alloy cowling. The fuselage was a wooden monocoque with an integral fin. A cockpit with a sliding, multi-panel canopy was situated over the trailing wing root, merging into the raised upper rear  fuselage behind it.  At the rear the tailplane was mounted on the upper fuselage.  Both elevators and the rudder were aerodynamically balanced, fabric covered dural structures.  In plan the horizontal tail was elliptical, with a small cut out for movement of the curved rudder, which extended down to the keel.

Though the G-28 had some of the characteristics of contemporary fighters, it differed in having a fixed tailwheel undercarriage. Each unfaired main wheel was on a cantilever oleo leg from the forward spar; the tailwheel castored.  Its armament was simple, with a single machine gun aimed with a reflector sight and monitored with a wing root camera.  A pair of underwing racks could each carry two bombs with weights up to .

The G-28 first flew on 22 May 1941.  It was flight tested by the VVS and found satisfactory, though Gribovsky hoped to install the more powerful MV-6A engine variant in production aircraft. After the German invasion of the USSR in June 1941, Gribovsky's priority became production of the Gribovsky G-11 assault glider and the G-28 was abandoned.

UC2 Kraka. Kraka, or UC2 Kraka was an amateur-built midget submarine completed in 2005, the first diesel–electric amateur sub in Denmark. It was built by Peter Madsen, Claus Nørregaard and several other people. The overall length was , and it displaced 6 tonnes. The propulsion was diesel–electric with a 16 hp diesel engine and an 8 hp electric motor. Kraka can be seen at Denmark's Technical Museum in Elsinore (aka Helsingør).
Kraka is named after a woman in Norse mythology known for her intelligence.

Construction
The sub was built at Peter Madsen's workshop in Farum, Denmark. Construction took  years and over 3600 hours to build. It was built with two engines, a diesel and an electric, making the sub a diesel-electric. With a diesel drive, this theoretically allows the sub to have a  range, and up to  submerged. It can run at a speed of  on the surface, and  submerged, using the snorkel and with extra fuel aboard. The boat is  long,  wide,  with dive planes, and  high from keel to top of periscope. On electric drive, it has a range of . On diesel drive, it has a range of . It has a nominal dive depth of , but the crush depth is theoretically . Maximum operational depth is . It has a 40kW Volvo Penta MD 19 diesel and a 6kW Sauer Danfoss 24V DC electric motor. The marine diesel engine was 65 years old when it launched in 2005. Backing the electric is 24V 400Ah Sectronic-Fram GS gel battery. UC2 has two sets of balance tanks, two main tanks and two trim tanks. With its flooding system, it takes only 20 seconds to reach neutral buoyancy. At the bottom of the sub is a dive lock, allowing emergency escape while submerged. The lock also allows use by divers while submerged. Unlike predecessor Freya, Kraka is equipped with an air compressor allowing for extended dive times. UC2 cost about 200,000 DKK to build. The sub can hold 4 people.

History
Construction started in 2002 and finished in 2005, when it was launched and put out to sea for voyages. At the time it was finished, it was one of only three diesel submarines in private civilian hands in the world, and one of only seven civil private sea-going submarines in the world.

After decommissioning, it was put on display, at Denmark's Technical Museum in Helsingor.

Peab. Peab AB (originally Paulsson Entreprenad AktieBolag ) is a construction and civil engineering company headquartered in Förslöv, Scania, listed on NASDAQ OMX Stockholm. It is the third largest construction company in Sweden and the Nordic region, with annual revenues exceeding SEK 50 billion. Peab has approximately 130 regional offices and 14,578 employees in Sweden, Norway and Finland.

History
The foundation of Peab was laid in 1959 by the brothers Erik and Mats Paulsson, then aged 16 and 14 respectively, to help farmers with refuse collection and disposal. However, the current name wasn't used until 1967, when the brothers created the limited company Bröderna Paulsson Peab AB, shifting focus towards construction at the same time. The company expanded in southern Sweden by acquisitions throughout the '70s and '80s.

Peab finally reached national coverage in 1991, after a merger with the OTC-traded company Hallströms and Nisses AB; a company whose market was Stockholm and northern Sweden, supplementing Peab's market coverage. The first international expansion occurred in 1994, when Peab acquired Fagbygg A/S in Norway, which later merged with NOR Gruppen A/S, making it the fourth largest construction company in Norway. In 1999 the company entered the Finnish market, after acquiring Rakennus OY Leo Heinänen, which was complemented with Seicon and Vasa Betong in 2003.

In 2011, Mats Paulsson stepped down as CEO, moving into the position of Vice Chairman of the Board. Erik Paulsson with family sold their shares in Peab to Mats Paulsson and his family in 2014.

Business areas
Peab is organized into four business areas, serving both external customers and internally, to other units in the company:

 Construction — Performs contract work for new construction, renovation and maintenance
 Civil Engineering — Offers civil engineering on infrastructure projects, as well as maintenance of roads
 Industry — Delivers material and equipment
 Project Development — Offers housing and commercial property development services

Construction is the largest business area, accounting for almost half of the operative net sales and share of employees in 2013. Approximately 80% of the sales were located in Sweden.

Bribery scandals
PEAB has been involved in a number of bribery scandals during the construction of Friends Arena. A high level manager was bribed with a sailing boat by a subcontractor. In addition, founder Erik Paulsson was charged with bribery of city director Sune Reinhold of Solna city.

Mack model EH trucks. The Mack model EH trucks were a family of 4x2 trucks used by the US and British military before and during World War II. They were built in conventional and cab-over-engine models and were used as both trucks and semi-tractors. Originally a commercial design, in 1943 a military version became standard.

History 
In 1937, the US armed forces bought Mack's commercial E series in small orders, the EH was the largest model. In 1942, large numbers of modified trucks were supplied under Lend-Lease to Britain and many could be seen carrying the L or H-numbers of the British War Department. They differed from the commercial type by lacking chrome trim and nameplates, and were fitted with a military style cargo body with canvas cover. They were painted olive drab all over. 510 EH, 70 EHU, 140 EHT with semi-trailers ST20, 180 EHUT with semi-trailers ST20 were delivered.

In 1943 a military design version of the EH type was destined mainly for Defense Aid. From the total of 3450 EH produced, 2400 were supplied to Britain.

After the war, the E series commercial production continued until 1950.

Engine and driveline 
The standard engine was the EN310 (Mack) 6 cylinder L-head petrol engine, a Buda Engine Co. 6DT389 diesel was available. Some modified EH and all military design trucks had an EN354 engine, a   L-head inline 6 cylinder gasoline engine developing  at 2800 rpm and  of torque at 1150rpm. Some transmissions were direct in 4th and overdrive in 5th gear, while others were direct in 5th. The rear axle was a double-reduction full-floating “banjo” type.

Chassis 
The EH had a ladder frame with two beam axles on leaf springs. The military models had two wheelbases, the  short for tractors and the  long for straight trucks. The variant EHUS had a shorter wheelbase at . They were used as fuel servicing trucks in the US Navy or as wreckers for the USMC. The bus chassis had a  wheelbase.

Commercial types had split-rim wheels and hydraulic brakes, military types had disk-type wheels and air brakes. The tires were 9.00x20.

Models 
There were four basic models. The EH was a conventional straight truck chassis, EHT was a conventional semi-tractor. The EHU was a C.O.E. straight truck chassis, and the EHUT was a C.O.E. semi-tractor. A C.O.E. can have a longer body, but the engine is harder to work on.

Besides the cargo and semi-tractor, there were fuel and water tankers, van bodies, wreckers, bus chassis, and fire trucks.

M1 medium tractor. Prior to and during the second world war the US Army called several tractors M1 medium tractor. Under the Ordnance Corps these "off the shelf" tractors were meant to tow artillery pieces, so were not equipped with blades like their engineer counterparts. Eventually these were replaced by purpose built "high-speed tractors" (HST). Some tractors were equipped with crane attachments for ammunition, and material handling.
