User Location Service. In computing, User Location Service was a standards-based protocol for directory services and presence information, first submitted as a draft to the IETF in February 1996.

Client software supporting ULS included early versions of Microsoft Netmeeting, Intel Video Phone and FreeWebFone. Netmeeting had depreciated ULS in favour of Internet Locator Service by 1997 and FreeWebFone no longer exists.

A ULS server provides directory services and presence lookup for clients.  At one stage, public ULS servers were made available by Microsoft and others, but these have largely been abandoned.

ULS typically runs on the TCP port 522.

British Rail Class 22. The British Rail Class 22 or "Baby Warship" was a class of diesel-hydraulic locomotives designed for the Western Region of British Railways and built by the North British Locomotive Company. They were very similar in appearance to the Class 21 diesel-electrics, although shorter in length by almost five feet. The nickname Baby Warship related to the similarity in appearance (and internal equipment) to the British Rail Class D20/2 or Class 41 Warship Class. The Class 22s were numbered D6300-D6357.

History

Introduction

D6300 was introduced to traffic in 1959 and deliveries continued until 1962. The Class 22s were allocated to Bristol Bath Road, Laira Plymouth, Newton Abbot and Old Oak Common. The majority of the class always operated in the West of England, on a range of local passenger and freight work, with smaller numbers of the later units operating on local work in the Bristol area and around London Paddington (notably moving empty carriages between the main station and Old Oak Common yard).

Availability
Initially the locomotives had some problems with engine and transmission faults, but could be returned to North British Locomotive Works (NBL) for repair under the contractual agreement. By 1961, reliability had improved, but with the more powerful locomotives of Classes 35, 42, and 43 now being available, the locomotives were displaced onto more secondary duties, including work on the former Southern Region lines west of Exeter. By the mid 1960s, the locos had settled down to give reliable service, with availability over 85%.

Decline
NBL went bankrupt in 1962 and, by the late 1960s, withdrawn locomotives were being used to provide spares. Attrition was inevitable and the withdrawals, which had commenced in 1967, finished with the withdrawal of 6333, 6336, 6338 and 6339 on 1 January 1972. Ex-London Midland Region Class 25 diesel-electrics were drafted in as replacements.

Livery 

The NBL type 2s were introduced in all-over green livery with a light grey skirt band, mid-grey roof, red buffer beams and black underframe. Numbers appeared below all four cab windows and the BR 'lion and wheel' emblem was placed high on the bodyside as centrally as possible. Later a small yellow warning was added. From 1967 some locos were repainted in the new corporate rail blue livery. The first four repaints, D6300, D6303, D6314 and D6327 had small yellow warning panels which they retained until withdrawal, later blue repaints had full yellow ends. Only about half the class were repainted into blue. The BR logo was placed immediately below each cab window, with the loco number below this; on some locos this was reversed.

Models 
Dapol released a 00 gauge model of the class 22 in late 2011.

Smeg (appliances). Smeg () is an Italian upmarket home appliance manufacturer.

History 
Founded in 1948 by Vittorio Bertazzoni as an enameling and metalworking company, the company preserves the memory of its original purpose and location (Guastalla, Reggio Emilia) in the name acronymised as Smeg, Smalterie Metallurgiche Emiliane Guastalla ("Emilian Metallurgical Enamelling Works Guastalla").

During the 1950s the company’s metalworking background was accompanied by the production of its first cooking appliances. In 1956, the company presented "Elisabeth", one of the first gas cookers equipped with automatic ignition,  a safety valve in the oven and a cooking programmer.

In the 1960s, Smeg introduced its first washing machine, the Leda, and then the large 60 cm Niagara dishwasher, with capacity for 14 place settings.

In 1971, the company began production of built-in hobs and ovens.

Other activities 
Smeg started in the residential sector, and later entered the commercial market. Smeg Foodservice manufactures appliances for the hotel, restaurant and catering market, and Smeg Instruments supplies disinfection equipment to hospitals and dental surgeries.

Business 
The design and manufacture of Smeg appliances is concentrated in four factories based in Northern Italy, each specialising in a specific type of appliance. Smeg has subsidiaries worldwide, overseas offices and an extensive sales network. Smeg has developed products in collaboration with architects and designers including Guido Canali (who also designed the company headquarters in Guastalla), Mario Bellini, Renzo Piano, Marc Newson and deepdesign.

Production takes place in six plants in Italy and China (Guastalla, Milan, Turin, Chieti, Bonferraro and Shenzhen). The subsidiary SMEG Deutschland GmbH is active in Germany. SMEG is represented worldwide with 16 branches, in Great Britain, France, Belgium, Netherlands, Germany, Sweden, Denmark, Spain, Portugal, Russia, Ukraine, Kazakhstan, South Africa, USA, Australia, Mozambique as well as two representative offices in Hong Kong and Saudi Arabia.

FAB 1950s-style appliances 

In 1997, Smeg introduced refrigerators styled similarly to 1950s models, in several colours, with model names prefixed "FAB", and bearing the distinctive SMEG logo. The FAB line remained in production, with technically modern appliances with 1950s appearance. The FAB28 had deep curved doors and a large handle. Fridge-freezers were later introduced, with more colour options, and special editions such as a Union Jack door. In 2014, small domestic appliances such as toasters and kettles were added to the FAB 50s range.

Awards 
 2010: Good Design Award granted by the Chicago Athenaeum, Museum of Architecture and Design and the European Centre for Architecture, Art, Design and Urban Studies, for the FP610SG oven and the P755SBL hob from the innovative Newson product line.

Carl Pollock. Carl Arthur Pollock, OC (1903 – August 16, 1978) was a Canadian businessman. Born in Kitchener, Ontario, graduated from the University of Toronto in electrical engineering. A scholarship from the Massey Foundation financed two years at Oxford University, England. At university he showed exceptional talent in track and rowing.

He taught for a short time at the University of Toronto, but his father's illness led him to choose a career in business and industry at the Kitchener electronics firm his father founded in 1907, Electrohome. Pollock joined the firm in 1930, was president from 1951 to 1972, and oversaw the most successful years of Electrohome's history.  During the decades to follow, Electrohome produced many different consumer products, including furniture, electric motors, small appliances, and most importantly, radios and televisions. By 1965, Electrohome products were being sold in 23 countries. Total sales in 1968 were $44.5 million. By end of the decade, Electrohome was the second largest employer in the Kitchener-Waterloo area, and colour television was the company's largest single product line. In fact, Electrohome engineered, designed, and manufactured the only Canadian colour television receiver.

He was also the founder of several media outlets in Kitchener, including CKKW, CFCA and CKCO.

Pollock was a member of the National Design Council and in 1963 he became president of the Canadian Manufacturers' Association. He was convinced that Canadian technology and industry would take no second place. His own firm led in introducing several firsts in the electronics field.

In 1975, he was made an Officer of the Order of Canada "for his many services to industry, particularly in the field of electronics and for a variety of community activities." He was a founder of the University of Waterloo, chairperson of the board of governors for eleven years and chancellor from 1975 to 1978. He was a founder of the Stratford Festival of Canada and supported musical groups, including the Kitchener-Waterloo Symphony Orchestra.

His son John A. Pollock took over the role of 3rd generation president of Electrohome in 1972, and led the company into a number of different electronics businesses, primarily industrial. The most successful products during this period was a line of data, video, and graphics projectors. Electrohome eventually was dissolved in an orderly wind down in late 2008.

At University of Waterloo, the engineering building CPH (Carl Pollock Hall) is named after him.

Politechnika Warszawska PW-6. The Politechnika Warszawska PW-6U is a Polish two-seat training sailplane designed at the Warsaw University of Technology for basic flight instruction and transition training to the PW-5 single-seater. It was manufactured at PZL Świdnik from 2000 and at ZS Jezow from 2007.

Development
The PW-6 was designed to be an ab initio trainer with the capability of providing cross-country training as well. It has handling and performance characteristics similar to the Politechnika Warszawska PW-5. In this way, it was envisaged that the transition to solo flying in the single-seater could be made sooner.

The prototype of the PW-6, built at the Politechnika Warszawska, PZL Świdnik and DWLKK, made its maiden flight from Bemowo Airfield, Warsaw, in July 1998. Type certification was granted in September 2000, after Jerzy Kedzierski and Maciej Lasek completed the test flights. Serial production started at PZL Swidnik soon afterwards, with first deliveries to Egypt, New Zealand, Belgium, Canada, United States, Portugal and Germany. Production at PZL Swidnik ceased after approximately 26 aircraft had been completed, but resumed at Zaklad Szybowcowy Jezow in 2007.

Design
Classical shoulder-wing, two seater, tandem layout, designed in accordance with the requirements of JAR-22 Utility Category.
Wing shape and profile are similar to the PW-5 design: trapezoid plan with bow-shaped ends, shoulder-set on the fuselage, having a single-spar structure with sandwich shells. Schempp-Hirth-type air brakes extend on the upper wing surface only.
Fuselage shell of glass-epoxy composite monocoque structure, stiffened with frames. Fabric-covered rudder.
Fixed undercarriage consisting of main wheel behind the rear pilot, with shock absorber and drum brake, a smaller front wheel and a tail wheel to prevent ground scraping if over rotation takes place during take off or landing.
Two tow releases, for aerotowing and winch-launching.

Variants
The following derivatives were projected, though not built:
PW-7 Motorglider project: two seater side-by-side motorglider, with PW-6 wing geometry.
PW-9A Aerobatic Training Glider, with automatic control connections and tail ballast compartment.
PW-9M Self Launching Training Glider, with Solo engine and folding propeller.

GER Class S56. The  GER Class S56 was a class of  steams designed by James Holden for the Great Eastern Railway.  Together with some rebuilt examples of GER Class R24, they passed to the London and North Eastern Railway at the grouping in 1923, and received the LNER classification J69.

History
The Class S56 were a development of the Class R24, being almost identical, apart from higher boiler pressure and larger water tanks. Twenty were built in 1904 at Stratford Works.

All twenty passed to the LNER in 1923. Thirteen class J69 locomotives were lent to the War Department in October 1939, of which five had been built as Class S56. They were sold to the War Department in October 1940, where they were used on the Melbourne and Longmoor Military Railways. The remaining locomotives were renumbered 8617–8636 in order of construction; however gaps were left where the locomotives sold to the War Department would have been. At nationalisation in 1948, the remainder passed to British Railways, who added 60000 to their number. Post-war withdrawals started in 1958, and by 1962 all had been retired.

Preservation

GER no. 87 (LNER 7087, 8633, BR 68633) has been preserved, initially at the Clapham Transport Museum, and now at the National Railway Museum. It is currently on display at Bressingham Steam Museum.

Dippel's oil. Dippel's oil (sometimes referred to as bone oil) is a nitrogenous by-product of the destructive distillation of bones. A dark, viscous, tar-like liquid with an unpleasant smell, it is named after its inventor, Johann Konrad Dippel. The oil consists of aliphatic chains, with nitrogen functional groups including  pyrroles, pyridines and nitriles, as well as other nitrogenous compounds.

Dippel's oil had a number of uses, which are mostly obsolete. Its primary use was as an animal and insect repellent. It saw limited use as a chemical warfare harassing agent during the desert campaign of World War II. The oil was used to render wells undrinkable and thus deny their use to the enemy. 
By not being lethal, the oil was claimed to not be in breach of the Geneva Protocol.

Research Unix. Research Unix refers to the early versions of the Unix operating system for DEC PDP-7, PDP-11, VAX and Interdata 7/32 and 8/32 computers, developed in the Bell Labs Computing Sciences Research Center (CSRC). The term Research Unix first appeared in the Bell System Technical Journal (Vol. 57, No. 6, Part 2 July/August 1978) to distinguish it from other versions internal to Bell Labs (such as PWB/UNIX and MERT) whose code-base had diverged from the primary CSRC version. However, that term was little-used until Version 8 Unix (1985), but has been retroactively applied to earlier versions as well. Prior to V8, the operating system was most commonly called simply UNIX (in caps) or the UNIX Time-Sharing System.

History 

AT&T licensed Version 5 to educational institutions, and Version 6 also to commercial sites. Schools paid $200 and others $20,000, discouraging most commercial use, but Version 6 was the most widely used version into the 1980s. Research Unix versions are often referred to by the edition of the manual that describes them, because early versions and the last few were never officially released outside of Bell Labs, and grew organically. So, the first Research Unix would be the First Edition, and the last the Tenth Edition. Another common way of referring to them is as "Version x Unix" or "Vx Unix", where x is the manual edition. All modern editions of Unix—excepting Unix-like implementations such as Coherent, Minix, and Linux—derive from the 7th Edition.

Starting with the 8th Edition, versions of Research Unix had a close relationship to BSD. This began by using 4.1cBSD as the basis for the 8th Edition. In a Usenet post from 2000, Dennis Ritchie described these later versions of Research Unix as being closer to BSD than they were to UNIX System V, which also included some BSD code:

Versions

Legacy 
In 2002, Caldera International released Unix V1, V2, V3, V4, V5, V6, V7 on PDP-11 and Unix 32V on VAX as FOSS under a permissive BSD-like software license.

In 2017, Unix Heritage Society and Alcatel-Lucent USA Inc., on behalf of itself and Nokia Bell Laboratories, released V8, V9, and V10 under the condition that only non-commercial use was allowed, and that they would not assert copyright claims against such use.

Pliny Earle I. Pliny Earle I (December 17, 1762 – November 19, 1832) was an American inventor who made wool and cotton carding pickers.

Biography
Pliny Earle I was born in 1762 in Leicester, Massachusetts, the son of Sarah and Robert Earle.

In 1785, he teamed with Edmund Snow in the manufacture of carding machines for cotton and wool. Among the many obstacles encountered by Samuel Slater in the introduction into the United States of the manufacture of cotton by machinery was the difficulty of procuring card clothing for his machines.

After unsuccessful applications to several other persons, he went, in 1790, to Earle, who, although it was a new and untried work, agreed to make the cards. He succeeded, but to achieve that success he was obliged to prick the holes for the teeth with two needles fastened in the handle. This led him to the invention of the machine for pricking "twilled" cards, by which the labor of a man for fifteen hours could be performed in as many minutes. This machine was in general use for years, until the machine that both pricks the leather and sets the teeth superseded it. He was a member of the Society of Friends, and, apart from his inventive genius, made extensive attainments in science and literature.

Earle subsequently took little part in political affairs. He devoted his time principally to literary work, and published an Essay on Penal Law; an Essay on the Rights of States to Alter and to Annul their Charters; Treatise on Railroads and Internal Communications (1830), and a Life of Benjamin Lundy. At the time of his death he was engaged in a translation of Sismondi's Italian Republics, and in the compilation of a Grammatical Dictionary of the French and the English Languages.

He died in Leicester, Massachusetts in November 1832 and is buried at Quaker Cemetery.

Cryomodule. A cryomodule is a section of a modern particle accelerator composed of superconducting RF (SRF) acceleration cavities, which need very low operating temperatures (often around 2 Kelvin). The cryomodule is a complex, state-of-the-art supercooled component in which particle beams are accelerated for scientific research. The superconducting cavities are cooled with liquid helium.

A cryomodule section of an accelerator is composed of superconducting cavities that accelerate the beam, also including a magnetic lattice that provides focusing and steering.

Design considerations

SRF cavities tend to be thin-walled structures immersed in a bath of liquid helium having temperatures of 1.6 K to 4.5 K. Careful engineering is required to insulate the helium bath from the room-temperature external environment.  This is accomplished by:
 A vacuum chamber surrounding the cold components to eliminate convective heat transfer by gases.
 Multi-layer insulation wrapped around cold components.  This insulation is composed of dozens of alternating layers of aluminized mylar and thin fiberglass sheet, which reflects infrared radiation that shines through the vacuum insulation from the 300 K exterior walls.
 Low thermal conductivity mechanical connections between the cold mass and the room temperature vacuum vessel.  These connections are required, for example, to support the mass of the helium vessel inside the vacuum vessel and to connect the apertures in the SRF cavity to the accelerator beamline.  Both types of connections transition from internal cryogenic temperatures to room temperature at the vacuum vessel boundary.  The thermal conductivity of these parts is minimized by having small cross sectional area and being composed of low thermal conductivity material, such as stainless steel for the vacuum beampipe and fiber reinforced epoxies (G10) for mechanical support.  The vacuum beampipe also requires good electrical conductivity on its interior surface to propagate the image currents of the beam, which is accomplished by about 100 μm of copper plating on the interior surface.
