Title: Improvements in knitted stretch fabric and a method of making the same
IPC: D04B1/10
Filed: 1958-02-10
Abstract: 874,799. Knitting. URLAUB, G. A. Feb. 10, 1958, No. 4325/58. Drawings to Specification. Class 74 (2). An interlock fabric is knitted on a circular machine in which spaced needles in one bed have a cutting edge in the hook and on the latch so as to sever the corresponding loops on one face of the fabric to produce visible lines of weakness. The associated needles of the other bed are rendered inoperative so that the yarn on the other face of the fabric floats across these wales. Strips of material suitable for bandages may subsequently be provided by cutting along the float wales. Other means of providing weakening lines along wales may be employed such as using special cutting sinkers, or reinforcing except in spaced wales. The fabric also may be produced on flat, straight bar and warp machines.

[Class 100 (iii)] Magazines.-Means for facilitating removal of a magazine from its base frame are so arranged as to be normally within the confines of the frame and to be movable out of the frame in the plane thereof, in order to support the magazine in a vertical position, so that it can be lifted off. The base frame B, Figs. 1 and 2, of each magazine contains a pair of telescoping slides L<1>, L2, the upper L<1> of which carries at the front end a cross-piece L. The magazine A is raised until a cross-rib A<1> at the forward end clears retaining-shoulders B<1> on the base frame, and is then slid forwards until another cross-rib A<2> engages the cross-piece L. The further movement of the magazine extends the slides L<1>, L<2>, so that it can be swung down into the vertical position, in which it hangs from the cross-piece, brackets A<3> on the rib A<2> serving to hold the magazine in place. The magazine is replaced by hanging it on the cross-piece and tilting it up. As the magazine is pushed back, brackets A6 engage the cross-piece and effect the return of the slides into the base frame. In a modification, the slides are replaced by two arms M, M<1>, Fig. 5, pivoted at opposite sides of the base frame, and connected by a pin m<5> passing through slots m<6>. As the magazine is drawn forwards, plates A<10> on its underside engage lugs m<4> on the ends of the arms M, M<1> and swing the arms outwards, so that the magazine can be suspended from them. In another form, the pivoted arms have toothed segmental portions, which gear together and cause the arms to move in unison.

Abstract: 1420107 Amplifier arrangements WESTERN ELECTRIC CO Inc 30 Jan 1973 [31 Jan 1972] 4553/73 Headings H3T and H3W In an amplifier circuit for amplifying an input signal S(t), Fig. 3, having both amplitude and phase variations including means 10 for deriving from the input signal S(t) a pair of constant amplitude phase modulated components S<SP>1</SP> 1 (t), S<SP>1</SP> 2 (t), the phase modulation of each of the two components is proportional to the arc sine of the amplitude variations of the input signal S(t) and is in the opposite sense with respect to that of the other, means 28, 29 independently amplify each of the components by the same gain factor G<SP>1</SP> and the amplified components are linearly combined at 30. The amplifiers 28 and 29 can include non- linear amplifying devices such as power oscillators using Gunn diodes, Impott diodes or magnetrons which are phase or injection locked to S<SP>1</SP> 1 (t) and S<SP>1</SP> 2 (t). In Fig. 3, the input signal S(t) is passed to a limiter 21 which provides a constant amplitude phase modulated term output p(t) and to an envelope detector 22 which provides an envelope output E(t). The subcircuit 20 can be modified (Fig. 4, not shown) by replacing the detector 22 by a synchronous detector including a mixer (23) and a LPF (24). A feedback loop, containing a high gain amplifier 11, a phase modulator 12, a mixer 14, a low pass filter 15 and a resistor 16 operate on E(t) and p(t) to produce the constant amplitude phase modulated component S<SP>1</SP> 2 (t) which contains the phase fluctuation #(t). The other component S<SP>1</SP> 1 (t) is obtained from the output of a second phase modulator 19 having the same modulation characteristic as the phase modulator 12 and fed from the output of the amplifier 11 via an inverter 18. The output from the amplifiers 28 and 29 are combined at 30. The matched modulator requirement can be removed by providing a second feedback loop with its own high gain amplifier, phase modulator &c. for producing S<SP>1</SP> 1 (t) directly from E(t) instead of indirectly from V o (t). In a modification, Fig. 5, a low frequency signal S(t) such as in the 10's or 100's of MHz is separated to produce a S<SP>1</SP> 1 (t) and S<SP>1</SP> 2 (t) which are then translated in frequency using a common oscillator 41 and a pair of mixers 42 and 43. The outputs from the mixers 42, 43 are band pass filtered at 44, 45 and fed via amplifiers 46, 47 to a combiner 30.

Title: Process for the production of polysulphuric acid esters of polygalacturonic acid methyl esters
IPC: C07H7/033
Filed: 1953-02-19
Abstract: Polysulphuric acid esters of polygalacturonic acid methyl esters are prepared by reacting polygalacturonic methyl esters having a molecular weight greater than 15,000 with chlorosulphonic acid in the presence of a reaction medium of formamide.  Preferably, the methyl esters are reacted with a previously prepared mixture of chlorosulphonic acid and formamide at substantially room temperature. In general, a mixture of 1.5 to 3 ccs. of chlorosulphonic acid in 5 to 12 times its volume of formamide is used for each gram of polygalacturonic acid methyl esters.  The sulphated product may be isolated by pouring the reaction mixture into alcohol and filtering off the precipitate. The sodium salts of the esters are obtained on treating with sodium carbonate or bicarbonate.  As starting materials there may be used pectins from fruit, leaves and other parts of plants. Partial degradation products of pectin still of M.W. greater than 15,000 may also be used; the partial degradation is effected by reacting on the pectin with pectinase in a concentration of up to 5 per cent based on the pectin at a pH of 2 to 3 for a relatively short time without substantial saponification of the carbomethoxy groups. The polysulphuric acid esters of undegraded polygalacturonic acid methyl esters may also be degraded in this manner to yield polysulphuric acid esters still of M.W. greater than 15,000.  The products have anticoagulant properties.  In examples: (1) citrus pectin is treated in dilute acetic acid with Pectinol 100D and the degraded product of M.W. above 15,000 is recovered and sulphated with chlorsulphonic acid in formamide yielding a product having 3.96 per cent methoxyl content and 12.5 per cent sulphur; (2) citrus pectin is sulphated and then degraded to a M.W. of about 20,000 following the procedures of (1).ALSO:Pectin (polygalacturonic acid methyl ester) is degraded with retention of substantially all the carbomethoxy groups yielding products of molar weight in excess of 15,000 by reacting on the pectin with pectinase in an amount of up to 5 per cent based on the pectin at a pH value of 2 to 3 for a relatively short time, which may amount to 1/2 to 24 hours at a temperature between 10 DEG C. and 30 DEG C.  In an example, citrus pectin is treated in dilute acetic acid with pectinase at room temperature for 1 hour and then heated to decompose the ferment, the product being recovered by precipitation with methanol.  The degraded pectins are used to prepare polysulphuric acid esters thereof (see Group IV(b)).

Abstract: 373,192. Indicating faults in railway permanent way. CARDEW, C. A., St. Eerme, Ingram Road, Wahroonga, near Sydney, Australia. Feb. 16, 1931, No. 4868. Convention date, Feb. 21, 1930. [Class 105.] Apparatus mounted on a locomotive or other vehicle for indicating faults in railway and like permanent way is actuated only by relative movement of two remotely disposed unsprung parts, such as two axle-boxes on the same side of the vehicle, which are so connected to the indicating mechanism that a sidewise tilting of the sprung portion of the vehicle does not effect a differential movement of the members of the indicating mechanism which can only arise from a vertical movement of one axle-box relative to the other at a permanent way fault. The axle-boxes 1; 2 actuate bell-crank -levers 6, 7 on the suitably sprung main body of the locomotive to displace two members which are moved equally when the main body tilts sidewise and this movement is, therefore ineffective to operate co-operating electrical contacts. The contacts can only be operated by a differential movement of the two axle-boxes. The members may be two sliding or rocking elements carrying co-operating electric contacts and brushes but in the form shown in Fig. 2 the two bell-crank levers are connected by rods or by wires 8, 9 and tensioning springs 28, 29 to the ends of a lever 26 pivoted on a switch arm 20 ; equal movement of the wires 8, 9 which arises from a sidewise tilt turns the lever 26 without displacing its pivot 27, but a vertical movement of one axle-box relative to the other causes a displacement of the pivot 27 and therefore of the switch arm 20. One or more contacts 16 .. 19 are opened depending on the amplitude of movement and each contact serves to operate indicating and recording apparatus and apparatus to eject whitewash on to the permanent way. Fig. 14 shows the electrical control apparatus. When a permanent way fault is of sufficient amplitude to open a contact 126 a relay 167 is de-energized and at its back contact 170 picks up an auxiliary relay 176 the front contact 173 of which energizes a time relay 177, a winding 179 of an electromagnetic valve of a whitewash tank 162 for spraying the rails, an indication apparatus 175 such as a lamp or a recording apparatus, and a reclosing relay 178 the armature of which permits the relay 167 to be energized since the contact 126 is only briefly opened. The armature of the time relay 177 closes contacts in a holding circuit for the auxiliary relay 176 so that the indication and other apparatus is energized for a sufficient time. A lamp 166 is provided to indicate the correct setting of the switch controlled by the bell cranks. The apparatus may be provided on each side of the vehicle to test each rail and by extending the contact segments of the switch on one side of their centre, the apparatus will not give a double indication as may happen at low speeds.

Abstract: 413,053. Moving signs. SPECTAD DEVELOPMENT SYNDICATE, Ltd., 157, West George Street, and NOBLE, F., 38, Montrose Street, both in Glasgow. Feb. 17, 1933, No. 4873. [Class 3 (i).] A non-endless display band is wound on and off two rollers intermittently in each direction, with automatic reverse at each end of traverse, by a solenoid supplied with direct or, when fitted with a rectifier, alternating current. The period of display, and the time taken in effecting change of display, can be regulated separately by a dash-pot having adjustable air inlet and outlet valves, the return of the solenoid plunger during display being by gravity. One of the rollers is connected to its shaft by a spring which tensions the band, and the varying travel of the band due to change of effective size of the rollers, is compensated by the spacial disposition of the displays on the band. The rollers are geared together by chain and sprocket, the chain being driven a constant distance at each actuation by a shaft 13 geared therewith. The shaft 13 carries a disc 14 having notches 15 engaged by two pawls 19, 19<a> pivoted on linkages 16, 17 and pressed to the disc 14 by springs 20. The links 17 are pivoted to a cross-bar 11 on the solenoid plunger, and one of them is rendered ineffective by a guard 21 pivoted at 22 so as to lie on one side or the other and thus determine the direction of rotation of the shaft 13. A spring-pressed locking-bar 41 registers the disc 14. The reversal of the travel is obtained by a Geneva-stop 33 on the shaft 13 rotating a gapped disc 35 one step for each display, one or the other of two pins 36, 36<a> raising a spring- pressed catch 37 and releasing and subsequently pushing an arm 39 on the spindle 22 to move the guard 21. The display band is illuminated by lamps which are switched on during display by an arm 26 snapped against contacts 24 by a spring 27<a> coupled at its other end to a rod 27 fixed to the bar 11 to move up and down with the plunger. When the rod 27 comes to its bottom position it brings the arm 26 over to contacts 25 which make the solenoid circuit. Catches spring-held and released by a second arm moving vertically with the plunger time the exact moments of make and break of the arm 26. Specifications 311,014 and 325,973, [both in Class 3 (i)], are referred to.
