Title: Fiber optic connector for high density applications and method of manufacturing fiber optic connectors
IPC: G02B6/38
Filed: 1980-10-08
Abstract: The present invention relates to fiber optic connectors and, more particularly, to a fiber optic connector for optically interconnecting two high density sets of optical fibers and a method of manufacturing fiber optic connectors. While prior art fiber optic connectors are available, they are generally limited to connectors for a small number of communication channels. Recently, there has been a growing interest in and recognition of the need for, developing a suitable fiber optic connector for optically interconnecting two high density sets of optical fibers, particularly for single fiber cables, with low loss and minimum cross-talk characteristics. The connector of this invention satisfied this need. The connector includes a pair of connector members 22, 24 each having a rear end and a forward, mating end 30, 32. It also includes means 34, 36 associated with the forward, mating end of each of the connector members for terminating one high density set of optical fibers 38, 40, each of the terminating members including means for disposing the optical fibers of one high density set in a predetermined pattern. The connector further includes means 74, 76 for securing the connector members together with the forward, mating ends thereof adjacent. With these features of construction, the connector is well suited for optically aligning two high density sets of optical fibers. <IMAGE>

Title: Antifreeze for fuels
IPC: C10L1/12
Filed: 1981-01-22
Abstract: Fuel for internal combustion engines, particularly diesel engines, contains as a fuel antifreeze a combustible liquid which is miscible with petroleum fuel and with water, suitable antifreeze additives being methanol, 2-methoxyethanol and glycol ethers. The antifreezing additive prevents the freezing of water droplets entrained in the fuel, this ice formation being more commonly responsible for starting problems than actual freezing of the fuel itself. The fuel may also contain additives such as emulsifiers to promote dispersion of water droplets, low flash point liquid such as acetone or combustible oxidising agents such as methyl nitrate to facilitate cold starting, lubricants and corrosion inhibitors. A diesel tractor has been regularly run on the non-freezing fuel over a period of thirteen months during which time engine performance has not been affected and no starting difficulties during cold weather (down to -7 DEG C) have been experienced.

Title: A pressure compensated breakaway pipe coupling
Inventor: FLORY JOHN FREDERICK
IPC: F16L55/10
Filed: 1982-06-02
Abstract: A breakaway pipeline coupling comprises first and second pipe sections 12, 14 which cooperate to form a fluid seal and are designed to separate at a predetermined tensile load. A plurality of piston 20 and cylinder 18 pressure compensating devices are arranged around the exterior of the sections to hold them together until separation.

Title: Power converting system
Inventor: HATAKEYAMA TAKANOBU
IPC: H02M3/158
Filed: 1982-09-29
Abstract: The system converts electric power between ac (Ea) and dc (EL) and includes a chopping circuit (GTO1, GTO2;) connected to the dc output side of a full-wave thyristor bridge circuit (U1-W2; U1-W1, D1-D2; R1-S2). The system is controlled to reduce the output voltage from a maximum to a zero value by first reducing the duty cycle of the chopping circuit until a minimum pulse width is reached and then reducing the phase angle of firing of the thyristors of the bridge circuit. The arrangement enables conversion from max. to zero dc voltage with a high power factor. <IMAGE>
