Abstract: A door check device, for installation between a motor vehicle body and a motor vehicle door that swings in opposing opening and closing directions relative to the vehicle body, with an improved roller is provided. The roller includes a metal core having an internal bore and a molded plastic bushing lining the internal bore such that the metal core and the plastic bushing include interlocked or bonded structures that essentially prevent the relative rotation between the metal core and the plastic bushing.

Abstract: Provided is a novel method of dyeing a corespun yarn which comprises an inorganic fiber core and at least a first sheath. The method comprises: (a) contacting the corespun yarn with a dye liquor; (b) heating the dye liquor to a dyeing temperature for a time effective to dye the yarn; (c) cooling the dye liquor at a controlled rate; and (d) rinsing the yarn with water or with a mixture comprising the dye liquor and water. The dyed corespun yarn has a strength retention of about 80% or more based on the undyed yarn. The methods in accordance with the invention allow for the formation of uniformly dyed, high strength corespun yarns. Also provided is a dyed, corespun yarn which can be made by the inventive method, a fabric formed from the corespun yarn, as well as a product upholstered with the fabric. The dyed yarns exhibit substantially no “grin through” and little to no yarn strength loss after dyeing.

Abstract: A strut for mechanically coupling a driving member to a driven member in a planar one-way clutch is formed in a progressive die from a length of cold-formed metallic stock material such that the strut's diametrical member-engaging end surfaces are coextensive with a pair of cold-formed surfaces of the stock material. A pair of oppositely-projecting "ears" are integrally formed on the strut proximate to one of its end surfaces at one station of the progressive die. The ears cooperate with a complementary recess or pocket formed in one member's planar clutch face to thereby nominally position and maintain the strut's first end surface within the pocket. A surface on each ear is preferably coined at another station of the progressive die to thereby provide a relief which prevents deleterious contact between the ears and the opposed clutch face of the other clutch member.

Abstract: A steering column assembly. The steering column assembly comprises an upper column member and a lower column member mounted to the upper column member such that the upper column member can move relative to the lower column member. A shock absorption assembly is interconnected between the upper column member and lower column member. The shock absorption assembly includes a piston member and a piston receiver, the piston receiver including absorbing material which, upon impact to the upper column member, is compressed by the piston member within the piston receiver and extruded from the piston receiver so as to absorb impact energy as the upper column member moves relative to the lower column member.

Abstract: An improved gas turbine engine diagnostic system is disclosed which is particularly adapted for direct measurement of compressor performance, including efficiency and mass flow, for aircraft engines, without having to remove the engine form the aircraft. The system includes an instrumented compressor air discharge tube which has probes for total pressure, static pressure and temperature. The instrumented air discharge tube may be substituted for an existing air discharge tube for the engine to be tested, without having to remove the engine. Transducers attached to these probes provide signals which are connected to a data recorder or computer. Data can be taken as the engine is run, either on ground test or flight test. The total mass airflow output from the compressor stage for various engine performance settings can then be calculated using the static pressure, total pressure and air temperature measurements.

Abstract: A slat conveyor comprises a plurality of transverse slat units interconnected by links at the sides of the conveyor to form an endless chain-like structure mounted on sprockets at the ends of the conveyor, the slat units being fitted with rollers which roll along endless tracks. Each slat unit comprises a thin elongated plate having the longitudinal margins bent through an angle in excess of 90.degree. to form an inverted channel-shaped slat member and two side plates secured one in each side of the slat member. Each side plate is fitted with two locating studs and an axle spindle. Each slat unit is connected to an adjacent slat unit by two of the links arranged one on each side of the conveyor, each link having two bores which receive the studs on the associated side of one slat unit as a close fit and a third bore which receives the axle shaft on the associated side of the adjacent slat unit as a rotational fit.
