IBM 7701. The IBM 7701 Magnetic Tape Transmission Terminal was a communications device announced by IBM in  1960.  It was designed to transfer the contents of a reel of magnetic tape over a leased or dial telephone circuit.

The IBM 7702 was a similar device that could communicate at higher speeds. 

The 7701 was the first product introduced in conjunction with IBM's TELE-PROCESSING trademark.

Technical details

The 7701 communicated using the Synchronous transmit-receive (STR) communications protocol over either private or switched (message service) telephone lines.  It operated at speeds of either 75 or 150 characters per second (cps).  The 7702 operated at speeds of either 150, 250, or 300 characters per second.

The devices used a special incremental magnetic tape drive that was controlled by the STR communications unit.  The drive used standard one half inch, seven track magnetic tape reels recorded at 200 bytes per inch (BPI).  It moved the tape on demand in increments of  and was capable of reading data under the read/write head even when the tape was stationary.  Either binary or BCD tapes could be processed.

The 7701 could communicate with a remote computer system or with another 7701 or 7702.

Dimensions
The 7701 was  high,  wide, and  deep.

National Air Pollution Symposium. The National Air Pollution Symposium was held on November 10–11, 1949 in Pasadena, California by the Stanford Research Institute (now SRI International), along with assistance from the California Institute of Technology, the University of Southern California and the University of California.

SRI had performed much of the early research on air pollution and the formation of ozone in the lower atmosphere. About 400 scientists, businessmen, and politicians attended the event, which was the first event of its kind. The conference (and subsequent conferences) spurred some of the early pollution and climate change research, as well as early climate change legislation including the Air Pollution Control Act of 1955.

Russell City Energy Center. The Russell City Energy Center (RCEC) is a 619-megawatt natural gas-fired power station, which began operating in August 2013. It is operated by Calpine, and is located in Hayward, California. It is named for Russell City and is built on that community's former landfill site.

History
In 2001, the Calpine energy corporation developed plans to build a 619 megawatt power plant, the Russell City Energy Center, at the city's former location. The plant broke ground in late 2010. The plant borders the City of Hayward Waste Water Pollution Control Facility and property owned by East Bay Discharge Authority near the Don Edwards San Francisco Bay National Wildlife Refuge and the Hayward Regional Shoreline.

The Russell City Energy Center is the nation’s first power plant to receive a federal air permit that includes a voluntary limit on greenhouse gas emissions. A Federal Appeals Court, in May 2012, denied an environmental claim by nearby Chabot College. The plant went online in August 2013, and its full output of electricity is sold to Pacific Gas and Electric Company under a 10-year contract. Calpine Corporation owns 75% of the plant's peak dispatchable capacity, or 464 megawatts, and GE Energy Financial Services owns the balance.

On May 27 2021 an explosion at the plant shut down energy production. The city of Hayward is opposing the reopening until more is known about the cause.

Design and specifications
The power train consists of two Siemens Westinghouse 501 FD Phase 2 combustion turbine generators (CTG), each  maximum and each followed by a heat recovery steam generator (HRSG). The two HRSGs are heated from the CTG exhaust gases to generate steam. The generated steam is let in a single steam turbine generator (STG) of  maximum. Resulting peak output is  gross.

Under baseload operation, the output is  gross from each gas-turbine and  gross for the steam-turbine, adding to  gross of which  consumed by the auxiliary equipment, yielding a  net output.

The two CTGs output the power at , the STG at , output which is connected to individual oil-filled generator step-up transformers, increasing voltage to . The auxiliary equipment motors are operated at 4,160 volts and the balance power distribution is operated at 480 volts and 277 volts for the lighting loads.

Production 
Russell City Energy Center's production is as follows.

Slade Brook. Slade Brook () is a  biological and geological Site of Special Scientific Interest in Gloucestershire, notified in 2003.

Location and habitat
The site, which includes an active tufa-forming stream, is in the Forest of Dean plateau and Wye Valley Area of Outstanding Natural Beauty. The stream system has a series of tufa dams, plunge pools and connecting stream sections.  This results from a combination of physical and chemical processes.

The Slade Brook rises on the Carboniferous Limestone of the Forest of Dean.  It flows for two kilometres before joining the River Wye, which is also notified as an SSSI. Approximately a kilometre section of the stream includes the main focus of tufa deposition.

Rainwater (which percolates into sinkholes in the limestone), is enriched with dissolved calcium carbonate. When emerging from springs along the brook, the removal of carbon dioxide causes precipitation of calcium carbonate. The main deposits of the calcium carbonate are at a series of dam-like structures, which are constructed of tufa.

The process is assisted by vegetation (which includes tree litter such as twigs and branches), algae and mosses. The flow of the stream is slowed and photosynthesis encourages the removal of the carbon dioxide.  The vegetation and debris then become the area for tufa accumulation.

The site is significant as tufa dams actively forming are relatively rare and this site has approximately sixty.  They enable research into the origins of fossil tufa dams as well as modern formations

Invertebrates
The white-letter hairstreak butterfly is recorded at this site.

Conservation
Natural England reports in March 2009 that the site remains in a favourable active condition.

German submarine U-399. German submarine U-399 was a Type VIIC U-boat of Nazi Germany's Kriegsmarine during World War II.

She carried out one patrol. She sank one ship and caused another to be declared a total loss.

She was sunk in the English Channel on 26 March 1945.

Design
German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-399 had a displacement of  when at the surface and  while submerged. She had a total length of , a pressure hull length of , a beam of , a height of , and a draught of . The submarine was powered by two Germaniawerft F46 four-stroke, six-cylinder supercharged diesel engines producing a total of  for use while surfaced, two Garbe, Lahmeyer & Co. RP 137/c double-acting electric motors producing a total of  for use while submerged. She had two shafts and two  propellers. The boat was capable of operating at depths of up to .

The submarine had a maximum surface speed of  and a maximum submerged speed of . When submerged, the boat could operate for  at ; when surfaced, she could travel  at . U-399 was fitted with five  torpedo tubes (four fitted at the bow and one at the stern), fourteen torpedoes, one  SK C/35 naval gun, (220 rounds), one  Flak M42 and two twin  C/30 anti-aircraft guns. The boat had a complement of between forty-four and sixty.

Service history
The submarine was laid down on 12 November 1942 at the Howaldtswerke (yard) at Kiel as yard number 31, launched on 4 December 1943 and commissioned on 22 January 1944 under the command of Oberleutnant zur See Kurt van Meteren.

She served with the 5th U-boat Flotilla from 22 January 1944 and the 11th flotilla from 1 February 1945.

The boat's first patrol was preceded by the short journey from Kiel in Germany to Horten Naval Base (south of Oslo), arriving at the Norwegian port on 28 January 1945.

Patrol and loss
U-399 departed Horten on 6 February 1945. On 21 March, she torpedoed the Liberty ship James Eagan Layne "about twelve miles off Plymouth". The ship was beached at nearby Whitesand Bay but settled on the bottom; at high water, only her masts and funnel showed. She was declared a total loss.

The boat sank the Dutch-registered Pacific on 26 March 1945. This ship had taken part in Operation Dynamo, the Dunkirk evacuation, in 1940.

U-399 was sunk later on the same day by depth charges from the British frigate .

Forty-six men died in U-399; there was one survivor.

Space Games. The Space Games is a  freefly skydiving competition event created by 'Father of ' FreeFly' Olav Zipser.   

In the early days of freeflying, Zipser wanted to get the best freeflyers at the time together to research, develop, and document the performance evolution of human freeflight / freeflying.

Human flight races, air games and competitions with an open-class and a pro-class were devised, and the first of its kind and first Space Games was held at Skydive America Palm Beach, Pahokee, Florida in 1997.

A total of 16 Space Games events were organised between 1997 and 2006, with cash prizes totalling as much as US$35 000 per event awarded to the winners of different categories.

The Space Games consists of human flight air races and competitions, and incorporates double elimination one-on-one races, open rounds, competition rounds, the FreeFly Indie 500, the FreeFly Atmosphere Dolphin Challenge, Fastest, Slowest and Furthest competitions, Freestyle, Sky Surf, and 3way and 4way FreeFly Challenges.

History

The Space Games came about as a result of the Atmosphere Dolphin FreeFly License Program ran through  Olav ZIpser's  First School of Modern SkyFlying.  Zipser used a constant speed and direction measuring device (space balls) around which high speed precision  freefly athletes could train and be tested to fly to the same standard.  This provided the testing ground for the research and development of freeflying, and opened up the possibility for a number of human flight air games and competitions.

The 1st Space Games was held at Skydive America Palm Beach, Pahokee, Florida in 1997.

The most recent and 16th Space Games was held at Skydive Sport Center Tortuga, Arezzo, Italy in 2006.

Toyo T-T.10. The Toyo Kukku T-T.10 is a low wing, single engine training aircraft which seats two in tandem.  It was designed and built in Japan in 1952.

Development
Toyo Aircraft was established in June 1952 and their first aircraft, the T-T.10, was completed by the end of the year. It is of mixed construction; the wing is built entirely from wood and fabric around two spars, with a plywood skin enclosed within fabric.  The flaps and ailerons are wood framed and fabric covered. In planform the wings are straight tapered with rounded tips; most of the taper is on the trailing edge. There is 6° of dihedral. The T-T.10's tail surfaces are also straight tapered with rounded tips, generally wood framed with fabric covering.  Its horizontal tail is mounted at the top of the fuselage. The  elevators have a cut-out to allow rudder movement, as the latter extends down to the keel. There is a trim tab on the port elevator.

The fuselage of the T-T.10 is fabric covered over a welded chrome-molybdenum steel frame. The engine is a 140 hp (104 kW) Lycoming O-290-D2 flat four, driving a two-bladed propeller. Student and instructor sit in tandem with dual controls under a multi-framed, continuous, two part sliding canopy. The rear fuselage line is raised compared with the forward section, but not to the full canopy height. The T-T.10 has conventional landing gear, with narrowly faired cantilever, coil spring damped mainlegs and a tailwheel.

The first T-T.10, registration JA3026, flew for the first time on 30 December 1952; the first production model (JA3049) followed soon after, on 11 February 1953. Production numbers are not known exactly; one report speaks of a "small batch" but only the first two T-T.10s appear in the single engine serial range JA3001 - JA3100, which covers the period August 1952 to September 1955, so they may constitute the whole batch.
