Patent GB-642720-A (GB)
Title: Improvements in and relating to knitting machines
Inventor: PEBERDY ROLAND
IPC: D04B9/10
Filed: 1947-01-24
Abstract: 642,720. Knitting-machines. BENTLEY ENGINEERING CO., Ltd. Jan. 24, 1947, No. 2314. [Class 74 (ii)] A latch-retarding member, which is engaged by the latches of the needles of a circular machine in the course of their relative rotation, is shifted to and fro, while the machine is in operation, between positions giving differing degrees of retard, by means operated by the machine itself. The shank 1a of a J- or L- shaped latch retarder 1 is slidably mounted in a block 4, so that its operative extremity 1b may be moved (against a return-spring 18) tangentially of the needle circle, toward or away from the knocking-over point 21, to vary the degree of retard. This movement is effected by a cam surface 8a on one leg of a stirrup 8 rockable around an axis 9 against the action of a spring 10. The position of minimum retard is determined by the position at which a stopscrew 12 on the stirrup cross-bar bears against the block 4: beyond that point, the stirrup 8 and the block 4 swing as one about the spindle 9, against the action of a spring 15, to raise the retarder 1 and swing it away from the needle cylinders, rendering it inoperative. The rest position of the block 4 is determined by the abutment of a, stop-screw 13 against an arm 14 protruding from the spindle 9; and the position of stirrup 8 corresponding to maximum retard by the abutment of a stop-screw 11, also on the stirrup cross-bar, against the block 4. The shank 1a of the retarder is telescopic, so that the positions of the end 1b may be pre-set. The stirrup is rocked from the maximum retard position to that of less retard (and, beyond that position, stirrup and block 4 are rocked together) by the control drum, acting through a connection 16. The block 4 and the stirrup 8 are also rockable together by the yarn changing mechanism, through a connection 17. The position of the retarder 1, lengthwise of the needles, may be adjusted by raising or lowering a vertical post 24, which carries the whole mechanism and may be integral with the spindle 9. In knitting a conventional sock, the latch retarder will be held inoperative, during welt formation, by the control drum. Prior to knitting a 1 x 1 rib band, which follows, the control drum allows the mechanism to move to the position of maximum retard. On the change-over to plated broad-rib or non-rib fabric the drum rocks the stirrup 8 to move the retarder 1 to reduce the degree of retard; and this position is maintained during the subsequent half-round splicing. When the heel yarn is substituted for the ground, plating and splicing yarns, the retarder is rendered inoperative by the yarnchange mechanism, acting through the connection 17, but is reintroduced thereby, with reduced degree of retard, at the end of the heel. Like operations take place in toe formation.

Title: Vehicle braking control
IPC: B60T8/60
Filed: 1969-01-15
Abstract: 1,254,643. Anti-skid braking systems. MESSIER. 15 Jan., 1969 [16 Jan., 1968], No. 2429/69. Heading F2F. [Also in Divisions G3 and G4]  A system for anti-skid control of fluid-pressure brakes on the wheels of an aircraft, includes three separate regulation circuits and a computer which latter computes the slip, g, where g = (w - w<SP>1</SP>)/w, w, w<SP>1</SP>, being the speeds of an unbraked and a braked wheel, respectively, the reciprocal of the former speed being approximated by the relation 1/w # a+bw - K log w (see Division G4). A first regulation circuit produces a signal to control the current in a coil B 1  of a transducer TR controlling braking pressure which signal, ST, is a function of the position of a brake-pedal and also of vehicle acceleration or deceleration. The former function has one of two levels, Fig. 8 (not shown), depending on the coefficient of friction of the ground, Fig. 7, while the slope of the law relating vehicle acceleration or deceleration to signal output, Fig. 6 (not shown), has one of two levels, Fig. 9 (not shown), again dependent on the ground surface. The resultant slip lies between the values g 1 , g 2 . Fig. 7, with corresponding brake pressure lying in one of two ranges. A second regulation circuit provides integral slip regulation, in this a reference slip signal g c  is added to the braked wheel slip signal g and the sum is integrated, the integral being positive or negative, Fig. 12 (not shown), according to whether g>g c  or not, this integral acting to correct the braking pressure. A third regulation circuit acts to control brake pressure as a function of slip, g. An amplifier 9 to which is fed a signal representing g supplies an amplifier 46 of which the gain is a parabolic function, its output signal controlling a solenoid coil B 4  of the transducer TR. Details of the circuits are given. (For Figures see next page.)

Abstract: 217,263. Union-Special-Maschinenfabrik Ges., and Maier, K. Jan. 31, 1923. Sewing-machines; channelling and channelclosing devices; presser-feet; feed; needde-guides. -Sewing-machines for work on leather and like material in which the sewing-thread is embedded, are provided with an adjustable knife which cuts the work in front of the needle along the line of feed to produce an incision parallel to the surface of the work. The presser-foot 24, Fig. 6, has an upright stud 30, Fig. 7, which is connected to the presser-bar 3 by a member 31. A member 1, Fig. 6, is yieldingly mounted on the end of the presser-bar 3 so as to be pressed on to the presserfoot 24. A U-shaped arm 1<a> on the member 1 encircles a guide-rod 4 to prevent lateral movement of the member. Slidably mounted in the member 1 is a rod 2, a head 5 on which adjustably receives the stud 6 of a knife holder 7 which carries a vertically-adjustable knife 10. Fixed to the opposite end of the rod 2 is a collar 11, an arm of which carries an axle 12, Fig. 2, which is embraced bv a U-shaped arm 13 of the member 1 to prevent rotation of the rod 2. A sleeve 14, rotatably journaled on the axle 12, but held from axial displacement thereon has a stud 14a on which is slidably mounted a ball 15. A rod 16<a> universally jointed to the ball 15 is fixed to the feed bar 17, so that the lateral movements of the feed bar are communicated to the rod 2, while allowing the member 1 to partake of the vertical movements of the presser-foot. During the feedstrokes, the presser is raised and the knife acts as an auxiliary feed-member. During the return movement to the right, Figs. 2 and 7, the knife slits the work. The knife 10 has a horizontal cutting portion 10<b> which extends in front of the vertical lip-raising portion in the direction of cutting. A device 33, Fig. 7, fixed to the knifecarrier, presses the work down in front of the knife during cutting to ensure uniform depth of incision. An interchangeable and adjustable channel closing strip 20 is mounted on the sleeve 1<c> of the member 1. A cam lever 27, Fig. 7, pivoted at 26 to the presser-foot engages a pin 28 on the member 1 so that the cutting apparatus can be raised bodily during sewing. If the presser-foot is raised by the usual hand lever 32, the cutting apparatus is also raised to release the work. In a modification for use on hard or dry leather, a member 44, Fig. 22, is fixed to the presser foot, a tongue 42 thereon engaging in the work-slit while a groove 48 acts as a needle-guide. An edge-guide roller 47 adjustably mounted on an arm 48 of the knife-holder 7 moves with the knife and prevents the work yielding during cutting.
