Abstract: 1512720 Angular motion transducer NISSAN MOTOR CO Ltd 24 Dec 1975 [28 Dec 1974] 52858/75 Heading G1N An angular displacement or velocity transducer consists in an annular member 26 of ferrite with alternate N and S poles magnetized along its periphery and secured for rotation with the crank-shaft 10 of an I.C. engine between the rim 16a of a crank-shaft pulley 16 and a non-magnetic support 22 secured to the crank-shaft by a bolt 24, passing through a cylindrical portion 22a. A roller bearing 30 is mounted on the portion 22a and an annular support 34 is secured to the bearing outer race 30b. The support 34 is prevented from rotating by a plate 42 screwed by bolt 44 to stationary engine stay 46, allowing adjustment of the precise location of the pickup head relative to the annular member but obviating the need for adjustment of the clearance between the head and the member. The support carries a pick-up head 40 disposed adjacent the outer periphery of the annular member so as to sense magnetic variations as the crank-shaft rotates. Electric signals representing angular displacement and velocity of the shaft are produced by the head.

Title: Method of preparing polyurethane elastomeric fibres having a set extensibility
IPC: C08G18/66
Filed: 1965-12-20
Abstract: Yarns and fabrics are made from elastomeric polyurethane fibres which are produced by forming a fibre of a reaction product of a diisocyanate, a glycol and a polymeric diol, drawing the fibre, and simultaneously or subsequently heat-setting the fibre at above 50 DEG C to reduce its extensibility to not more than 50% (Division B5-B6). Depending on the length of heat-treatment, the fibres may be given a temporary heat-set, the elasticity being recoverable by a heat-shrinkage treatment after the fibres are formed into yarns or fabrics, or given a permanent set, resulting in fibres and yarns having properties between elastic and non-elastic materials.  In Examples (1) a plain weave fabric consists of: warp:-worsted yarn 3/42/mm Z-twist, S-twist; weft:-worsted yarn as above plus 70/10 yarn of the heat-set polyurethane fibres having 94% extensibility.  The fabric is then heat-shrunk at 90 DEG C.  (2) Raw polyurethane yarn is drawn and heat-set to 91% extensibility and then incorporated with woolly nylon yarn to form a knitting yarn, which is then knit into a fabric using a rib stitch of 1:1.  The extensibility of the polyurethane yarn is then recovered by relaxing the fabric in water at 95 DEG C.  (3) A plain weave fabric consists of: weft:- polyurethane 70/10 yarn; warp:-mixed polyester and rayon yarn of 31/1's.  The fabric is relaxed in steam at 100 DEG C.  (4) Raw polyurethane yarn is drawn and heat-set to 98% extensibility.  The resulting 30/10 yarn is mixtwisted with cording yarn and woven into an interlock of 8/cm and course of 8/cm.  The fabric is relaxed in steam at 120 DEG C to recover the elasticity of the polyurethane yarn.  (5) Heatset polyurethane yarn and a mixed yarn of vinylon and cotton are used alternately as warp in a plain weave fabric having a weft of mixed polyvinyl alcohol fibre and cotton yarn.  The fabric is relaxed in water at 100 DEG C to recover the elasticity of the polyurethane yarn.  (6) Heatset polyurethane yarn is used as warp, and mixed vinylon and cotton yarn as the weft in a plain weave fabric, which is then heat-shrunk in water at 100 DEG C.

Abstract: 1,058,630. Valves. HONEYWELL Inc. Dec. 23, 1965 [Dec. 24. 1964]. No. 54523/65. Heading F2V. A ball-shaped valve member 41 of rubbery material is loosely mounted on a pin 40 passing diametrically through the ball. The pin is rotatable about an axis parallel to itself so that the valve member can be moved to engage and seal a flow port 12 opening into a valve chamber in which the ball is mounted. The pin is carried by a yoke 38 connected to a spindle 23 which is rotatable through gearing by an electric motor 78. The motor is such that it can stall safely when the valve member is arrested. A gear sector 71 loaded by springs 55, 56 is adjustable so that the valve may be made of normally open or normally closed type. Three positions of adjustment 50, 51, 52 are indicated in Fig. 3 (not shown), and are obtained by removably mounting the sector on an externally toothed part fast with the spindle. The operating gear assembly may also be turned through 180 degrees on top of a flange 14 of the valve body 10 to effect further adjustment. The valve member may close the inlet or the outlet port, or may selectively close two ports in a three-way valve arrangement. Alternative, e.g. pneumatic, actuating means may be used.

Patent GB-574000-A (GB)
Abstract: 574,000. Calculating-machines; interlocks. AKTIEBOLAGET FACIT. Oct. 27, 1943, No. 17762. Convention date, Nov. 30, 1942. [Class 106 (i)] A calculating machine for the four rules is provided with several interlocks. The invention is applied to the machine described in Specification 551,311 in which a pin-wheel rotor on a shaft 5 rotates in one or other direction according to which motor key 1, 2 is depressed. A pointed pawl 500 (Fig. 6, not shown), permits the actuation of only one of the keys 1, 2. The numeral keys 200 co-operate with crowding locking pawls 499 on a fixed bar 501 to permit depression of only one key at a time. As described in the prior Specification, three shift keys 197, 198, 199 are provided without interlock. Operation of a shift key rocks shaft 44 and a locking member 524 to engage pins 525 to lock the setting arms 31 for the pin wheels and therefore to lock the numeral keys 200. On the other hand, depression of a numeral key rocks the setting arms 31 via pins 38 so that the pins 525 lock the member 524 and therefore lock the shift keys. Operation of a motor key 1, 2 rocks a lever 331 clockwise to start the motor as described in the prior Specification, and' the cam surface 331a rocks an arm 505, Figs. 1, 5, counterclockwise to displace a bar 502 to its extreme left position, Fig. 1, to lock all the numeral and shift keys. It also locks the lever 515, Figs. 1, 3, in clockwise position to lock an arm 516 and hence to prevent clearing of the registers. At the same time, the arm 515c locks a spring-pressed lever 209, Fig. 4, a pin 209a of which holds the chief control lever 201, described in the prior Specification, in set position. The bar 502 remains in its locking position until the motor key 1, 2 is released and a cam disc 308, Fig. 5, on the shaft of the pin-wheel rotor, completes its current revolu. tion to permit a releasing arm 310 to rock away from the bent portion 331b of the contact lever 331, whereupon the arm 505 and bar 502 return to original positions and the contact lever 331 opens its contacts to stop the rotor. On the other hand, the bar 502 is locked in right-hand position by depression of one of the numeral or shift keys 197-200, or if the clearing arm 516 is rocked, as described in Specifica. tion 551,311, and then the bar 502 via the arm 505 locks the contact lever 331 and the motor keys 1, 2. Incorrect positioning of the chief control lever 201, Fig. 4, with the pin 209a out of one of the recesses, rocks the lever 209 counterclockwise which rocks the lever 515, Fig. 3, counterclockwise to block the bar 502 and therefore lock the motor keys. As described in the prior Specification, the addition and subtraction keys are coupled to the motor keys and share their interlocks. Specifications 351,276, 413,205, 431,623,; 431,627, and U.S.A. Specification 2,188.748 also are referred to.
