Abstract: ABSTRACT OF THE DISCLOSURE           A traction drive assembly for railbound vehicles comprises a motor-transmission unit, which is supported on at least one wheel set axle and consists either of a motor that extends in the longitudinal direction of the vehicles and angle drives flanged to said motor on both sides thereof, or of a motor which extends parallel to the wheel set axle and a spur gear set coupled to the output shaft of the motor. Each angle drive or the spur gear set is provided on its output side with a quill, which concen-trically surrounds the associated wheel set axle. In connection with such traction drive assembly it is proposed that each or the quill is connected to the associated wheel set axle by a flexible coupling, which permits an offset of axes and an angular misalignment of axes, and by an elastic bearing for transmitting the weight of the motor-trans-mission unit. The elastic bearing may be disposed laterally at the quill or within the quill. At least one lever, which is elastically pivoted to the motor and to the vehicle frame or bogie (truck), is provided as a backing element for taking up overturning moments and mass acceleration forces.

Abstract: ALKYLATION PROCESS                  Abstract of the Disclosure Alkylation of aromatic amines with ethers in the presence of iron oxide catalysts is described.  By means of the process aniline, o-toluidine, and the like can be selectively orthoalkylated with such ethers as dimethyl ether, diethyl ether, tetrahydrofuran, and 1,4-dioxane at elevated temperatures in the presence of a catalyst containing iron oxide.  With ethers such as dipropyl ether, diisopropyl ether and dibenzyl ether, N-alkyla-tion is the predominant reaction.  By appropriately modifying the iron oxide catalyst the process can be rendered selective for the para-alkylation of the amine.  An advantage of the process is that the unreacted ether is not extensively decomposed in the process and thus can be recovered for recycle or other use.

Abstract: KEYBOARD ENTRY SYSTEM      ABSTRACT      A keyboard entry system is disclosed which com-prises a keyboard which includes a plurality of letter keys, one for each letter of a selected language.  The entry system responds to conventional sequential acti-vation of individual keys by providing output signals indicative of the respective individual letters asso-ciated with the activated keys to an application program such as a word processor or printer control program. The keyboard entry system also responds to chords of simultaneously activated multiple keys by using these chords to retrieve stored words from a dictionary.  It is the stored words rather than the entered chords which are applied as inputs to the application program.  This system allows an operator to use both conventional se-quential key entry techniques and chorded entry tech-niques for rapid data entry.

Abstract: Abstract A new technique for forming CMOS custom logic circuits is disclosed wherein standard cells are used and the prior art technique of field oxide isolation is replaced with transistor isolation.  That is, the boundaries between the cells are formed by transistors that are permanently "off", i.e., tied to the positive or negative voltage supply, depending on whether the transistors are p-channel or n-channel devices, respectively.  Therefore, instead of having to deposit separate p+ and n+ source/drain diffusions for each cell, as in the prior art, a single p+ diffusion strip and a single n+ diffusion strip are utilized, where the polysilicon mask of both the logic and isolation transistors defines the cell sizes.  Thus, the p+ and n+ diffusions become generic steps which do not vary from circuit to circuit, decreasing the turnaround time associated with custom logic circuit layout and design.

The effective areas of the upper and lower diaphragms is designed to have a ratio of about 4 to 1.  An adjustable air by-pass valve is provided to adjust the air pressure acting on the upper diaphragm to permit ratio adjustment of the air pressure reaching the regulator to the fuel pressure reaching the engine, for example, a fuel injector leading to the engine.

Abstract: ABSTRACT OF THE DISCLOSURE    A direct-crimp coaxial cable connector having a captive inner pin contact includes a tubular main body which extends from the front end which serves as an outer ring contact to the rear end where the tubular main body is crimped over the cable braid of a coaxial cable.  A crimp ring is provided inside the rear end of the tubular main body and secures the cable braid of the coaxial cable against a ferrule which is inserted between the cable braid and the cable dielectric prior to crimping.  The ferrule captivates an insulator ring and an inner pin contact which are rear-loaded into the tubular main body of the connector prior to crimping.  A cylindrical contact insulator is secured inside the front end of the tubular main body, separates the inner pin contact from the front end of the tubular main body and secures the inner pin contact in combination with the insulator ring and ferrule.  Threads are provided on the inside surface of the ferrule to hold the ferrule in position during crimping, to help provide positive contact to the tubular main body and to captivate the insulator ring and inner pin contact.

Granted: 1990-03-13
Abstract: ABSTRACT OF THE DISCLOSURE:          The invention proposes a hydrophilic silicone composite useful as biomaterial,  and a method of producing it.   The hydrophilic silicone composite comprises a continuous matrix made of a crosslinked silicone polymer and contains from 10 to 150 parts by weight of a powdered hydrogel filler per 100 parts of such crosslinked silicone polymer.   The hydrogel filler has a particle size of from 10-6 to 10-1 mm, and is formed of particles of polymeric hydrogel made from physically or chemically crosslinked polymers or copolymers of glycol monomethacrylate polyol monomethacrylate or dihydroxyether monomethacrylate, amides of methacrylic or acrylic acid or their N-monosubstituted and N,N-disubstituted derivatives,  or from a multiblock copolymer of acrylonitrile with acrylamide or acrylic acid. The strength of this composite in dry from is substantially higher than the strength of the same hydrogel alone.   Its swelling in water and other solvents such as ethanol or ethylene glycolmonomethylether is much higher than would correspond to the content of hydrogel in the composite, and the lowering of its tensile strength by addition of swollen hydrogel is substantially less than would correspond to the silicone polymer in the composite.   Moreover,  the non-swollen composite has a strikingly high shape memory at temperatures above Tg.

Abstract: ABSTRACT: Bi-axial supporting arrangement.     The invention relates to a supporting arrangement for a rotatable element (16), as a rotating mirror or an-tenna included in a target seeker mounted at the nose of a projectile. The rotatable element (16) is supported by a bearing body, as a spherical ball (15), which is placed in a corresponding spherical recess (14) in a stationary part (12, 13). The ball (15) is supported by air or liquid in its recess so that it can perform both rational motion about a spin axis (10) and angular deflection motions about turning axes (01, 02) lying in a plane, which is perpen-dicular to the spin axis. According to the invention the angular deflection of the ball (15) about the said turning axes (01, 02) is controlled by means of magnetic fields, which are produced by magnetic yokes (25-27) provided with coils (22, 24). The yokes are terminated by magnetic poles (30-33) situated at the surface of the spherical recess (14) and cooperate with a magnetic, e.g. soft magnetic, part (29) of the ball (15).          -(Fig. 1).
