Title: Improvements in or relating to the crimping of yarn
IPC: D02G1/12
Filed: 1969-11-18
Abstract: 1285970 Stuffer-box crimping apparatus JOSEPH BANCROFT & SONS CO 18 Nov 1969 [21 Nov 1968 19 June 1969] 2427/72 Divided out of 1285969 Heading D1F The subject matter is as disclosed in Specification number 1285969 but the claims are directed to a stuffer-box crimper comprising variable yarn core choking means at the outlet of the crimping chamber. The choking means preferably comprise a pair of pivoted members 51 which are biassed towards each other. The members are mounted on the shafts 52 of a pair of gear wheels 57 which are urged to rotate, in the direction bringing the members 51 together, by a weighted line 55. In their retracted positions, the members 51 preferably register with the inner walls of the crimping chamber 10. In an alternative embodiment, the pivoted members form part of the walls of the crimping chamber when fully retracted.

Title: Improvements in or relating to dyestuffs suitable for sensitising photographic silver halide emulsions
IPC: C09B23/16
Filed: 1935-08-16
Abstract: Dyestuffs suitable for sensitizing photographic silver halide emulsions are prepared by condensing a quaternary salt of a heterocyclic nitrogen compound having a reactive thioether or selenoether grouping, or a reactive aminovinyl-, acylaminovinyl-, arylaminovinyl- or acylarylaminovinyl-group, with a compound containing two amino groups linked by a single bond or by a conjugate chain of carbon atoms some or all of which may form part of one or more aromatic carbocyclic rings, and which may be represented by the general formula <FORM:0461688/IV/1> , where n = o or a positive integer, or with a salt of such a compound.  Starting materials on the one hand are the specified reactive derivatives of substituted and unsubstituted thiazoles, thiazolines, oxazoles, oxazolines, selenazoles, selenazolines, pyridines, quinolines, indolenines, pyrimidines, thiodiazoles, quinazolines, benzthiazoles, naphthathiazoles and anthrathiazoles; and on the other hand hydrazine, o- and p-arylenediamines, benzidine, dianisidine, 2.2<1>-, 2.4<1>- or 4.4<1>-diaminostilbenes.  Reaction may be carried out in a solvent (alcohol or pyridine) with or without an acid-binding agent (sodium acetate or sodium ethoxide).  The resulting dyes are similar to those described in Specification 461,668 but contain in the linking chain two nitrogen atoms which are either adjacent or separated by a <FORM:0461688/IV/2> group or by a number of such groups.  In examples: (1) 1-methylthiobenzthiazole, 2-ethylthioquinoline, 1-methylthiobenzoxazole, dimethylthio - b  . b <1> - diazole, dimethylthio - a  . b  - diazole, 4 - methylthioquinazoline and 1 - methylquinoline - 4 - thione are respectively condensed with methyl-p-toluenesulphonate and the resulting salts condensed with hydrazine hydrochloride in pyridine: (2) 1-methylthiobenzthiazole is condensed with methyl-p-toluenesulphonate and the quaternary salt condensed with o - phenylenediamine, p - phenylenediamine dihydrochloride and benzidine respectively in pyridine: (3) 1.3.3-trimethyl-2-w-acetanilidovinylindolenium iodide is condensed in pyridine with hydrazine hydrochloride, p-phenylenediamine hydrochloride and dianisidine respectively, and in alcohol with benzidine: (4) 1-w-acetanilidovinylbenzthiazole ethiodide is condensed with p-phenylenediamine hydrochloride in pyridine, with hydrazine hydrochloride in alcohol in presence of sodium acetate, and with benzidine in alcohol: (5) 1-w-acetanilidovinylbenzoxazole methiodide is condensed with p-phenylenediamine hydrochloride in pyridine, and with benzidine in alcohol.  For sensitizing photographic silver halide emulsions one or more of the dyes may be incorporated in the uncast emulsion or the film or plate coated with the emulsion may be bathed in a solution of the dye; thus 100 c.cs. of a 1 : 1000 dyestuff solution may be added to 6,5 litres of emulsion, or the coated support may be bathed in a 1 : 1000 dyestuff solution.  Reference is made to Berichte 61, pages 59--62.

IPC: G01C13/00
Filed: 1916-03-03
Abstract: 104,527. Greer, W. M., (Reaks, H. G.). March 3, 1916. Indicators actuated by floats; indicators, alarm and signal.-In a device for recording and signaling the state of the tide a pencil p carried by a nut a working on a screw-threaded spindle b moves along a drum c rotated, for example, once in 24 hours, to give a graphic record of tidal movement. At the same time contacts m, m<1> moving in conjunction with the pencil control lamps l to signal the state of the tide. The spindle b is operated by a wire h passing round a pulley d secured to the spindle, one end of the wire being secured to a tide-operated float and the other to a suitable counterweight. The contacts m, m' may be carried by the wire h, or, as shown, by the nut a. The contacts move over conducting-strips n divided into insulated sections corresponding, for example, to feet and fathoms respectively. With low-power lamps, the lamp circuits may be controlled directly by the contacts m, m<1>, and strips n, but with high-power lamps, the contacts may operate relays which serve to control the lamp circuits. A modification is described in which the lamps burn gas or like illuminant, the relays serving to control valves regulating the supply to the individual lamps. The Specification gives a suitable lamp-group code. The " fathom " lights may be coloured, for example red for one fathom, and green for two.

Title: Improvements relating to impedance testing instruments for radio frequency energy
Inventor: CHARMAN FREDERICK JOHN HENRY
IPC: G01R27/02
Filed: 1956-02-02
Abstract: 854,878. Impedance testing instruments. ELECTRIC & MUSICAL INDUSTRIES Ltd. Feb. 4,1957 [Feb. 2,1956], No. 3271/56. Class 37. An impedance testing instrument comprises a feeder F for connecting an impedance Y to a source of oscillations S, means for detecting the relative amplitude. of oscillations transmitted from the source to the impedance and vice versa, and a variable reactance connected to the feeder to tune out the reactive component of the impedance; whereby the reactance of the impedance may be determined having regard to the variable reactance which gives the minimum reflection from the impedance. Two directional couplers D, D<SP>1</SP> measure respectively the amplitudes pl 0  and l 0  of oscillations reflected from impedance Y and transmitted from source S, and the variable reactance comprises a stub T having a movable element U. In operation, stub T is adjusted until its electrical length is a quarter wavelength of the oscillation from source S and [p] is then observed from meters M, M <SP>1</SP>. The electrical length ° of stub T is then varied until a minimum value P<SP>1</SP> is obtained. With reference to the simplified Smith's chart (Fig. 2) Y, B, G are the admittance, susceptance. and conductance of the impedance (Y=G+jB) A circle radius p <SP>1</SP> is constructed about centre G=1 intersecting the line B=O at G1, G2; the intersection of circles G=G1, G=G2 with vector 1 (i.e. a circle centre G = 1, radius [p] gives points Y1, Y2 for the load admittance from which alternate values of B1, B2 can be read off. The appropriate value of B is then indicated by the approximate ZO1 formula B = ZO1/ZO2 +an ° where ZO1, ZO2 are the impedances of the stub and feeder. The junction errors are removed by applying a true load at BB <SP>1</SP> and then adjusting stub T for zero reflection. In a modification, stub T is assymmetrically connected in a detachable length of feeder inserted between couplers D, D 1 and terminals B, B 1; this feeder can be reversed so that the instrument can be used in two ways, with different electrical lengths between the stub and load in each case.

During operation of the power-operated master cylinder, the plunger is driven into the cylinder and the pressure developed causes the legs 22 and 24 of the U-shaped packing member 20 to be forced apart to provide sealing engagement with the bore and plunger rod respectively. The disc 32 also " grows " radially under such pressure to provide an efficient seal. Behind the disc 32 is a support disc 34, preferably of a fabric impregnated thermal setting resin such as " Spauldite " and beyond that a back up disc of metal abutting against a snap ring 40.
