Abstract: 1391009 Polyacetylenic carboxylic acid salts EASTMAN KODAK CO 8 June 1972 [14 June 1971] 26799/72 Heading C2C [Also in Division G2] New polyacetylenic compounds of general formula where A<SP>+</SP> is an ammonium or substituted ammonium ion; B is a group of formula -CH 3 , -COO-, -COOR<SP>4</SP>, -CONHR<SP>5</SP>, or -OCONHR<SP>7</SP> where R<SP>4</SP> is H or C 1 -C 4  alkyl, R<SP>5</SP> is C 3 -C 10  alkyl which may be substituted, R<SP>6</SP> is alkyl or phenyl and R<SP>7</SP> is C 1 -C 8  alkyl which may be substituted, phenyl or substituted phenyl; n is at least 2; and x and y are each 0 or an integer from 1 to 10; are used in photographic materials. They may be prepared from known polyacetylenic compounds by known methods. For example, amine salts of amidesubstituted carboxylic acids may be prepared from polyynes having both carboxylic acid and carboxylic ester groups by treatment with an amine. Acid treatment of this salt yields the amide-substituted carboxylic acid which can in turn be treated with a different amine to form a different amine salt of an amide-substituted carboxylic acid.

Abstract: 659,759. Sewing; sewing - machines. MIKOLAS, F. Oct. 15, 1948, No. 26928. Convention date, May 2, 1947. [Class 112] Stitches.- A single - thread seam comprises on one side of the work a series of chain-stitches and a series of plain stitches, connected by double stitches on the other side. In the form shown in Fig. 9, the plain stitches c interlock with the chain-stitches a, and the double stitches d lie in the line of the seam, but in a modification the plain stitches and the chain-stitches lie in parallel lines with the double stitches, arranged transversely. Loop-stitching. - The seam is produced by a machine having a hooked needle 7, Fig. 9, and an eyed needle 6, carried in the same needle-holder on the lower end of a needle-bar 4, Fig. 4 (sectional plan) driven by the usual crank and pitman from the shaft 1; the needle-bar carries a take-up pin 31. A looper 25, Fig. 9, oscillating through 360 degrees, takes the thread loop from the eyed needle and carries it round the hooked needle for engagement by the latter. An auxiliary needle 8 is preferably associated with the hooked needle 7, acting 90 degrees out of phase with it so to strip the loop from the latter needle after it has descended and to close the hook during the drawing-up of a new loop. The needle 8 is associated with a guide plate 37 on the other side of the needle 7, both these members being carried by a vertically-sliding bar 16 actuated by a link 14 from an arm 12 on a spindle carried in a bearing 13 and oscillated by an arm 11 connected to an eccentric 9 on the shaft 1; the bearing 13 is clamped on a vertically slidable bar 18 connected by a screw 21 with the presserbar 20, so that the action of the auxiliary needle is related to the thickness of the work.. Presser-bars.-The presser-bar is pressed downwards by a leaf-spring 22 which bears on a nut on the screw 21 connecting the presser-bar with the bar 18. It is lifted by a knee-operated lever 33 engaging under the member 13 clamped on the bar 18 or by a finger-operated cam-lever engaging under the end of the knee-operated lever.

A length of cable to be test stretched is fastened at one end to a pin 16 in a fixed but adjustable carriage 4, Fig. 1b which is an extension of Fig. 1a, and at its other end is attached to a pin 5 in a carriage 3 which is movable on wheels 54 and is fastened to a long adjusting screw 46 extending right through a tubular piston and cylinder 24, Fig. 3 (not shown), to an abutment 21. In operation, the cable length is first tensioned by moving a locknut 47 to a position where it abuts the end of the ram 24, then the ram is operated to push against the nut 47 and move the carriage 3 away from the carriage 4. The second locknut 48 may be used to retain an initial load if due to the length or elasticity of the test cable the required breaking strain is not at once obtained. A power unit 45 incorporates measuring means to indicate the load applied by the ram. For Figs see next page

Abstract: 815,623. Floor polishing machines. BYLOCK ELECTRIC Ltd. Aug. 14, 1957 [Sept. 6, 1956], No. 27391/56. Class 138(1). In a machine for polishing, burnishing, scrubbing or cleansing floors or like surfaces of the kind having a plurality of disc brushes 1, e.g. three, rotatable about vertical axes and driven frictionally from a vertical motor-driven shaft, two brush-driving wheels 2 are supported by bearings 10 sliding towards and away from the shaft 8 in rectilinear slots 12 (in a base plate 3) by which they are guided, inclined to the direction of forward movement of the machine, so that during such movement the wheels 2 will tend to be forced into driving engagement with the shaft 8. The third brush-driving wheel 2<SP>1</SP> similarly mounted contacts the wheels 2 and is forward thereof, each slot 12 being substantially at right angles to the line joining the centres of the wheel 2<SP>1</SP> and the wheel 2 guided in the slot. Each wheel 2 is attached through a spindle 9 to a brush 1, each bearing 10 being mounted between plates 11, 15 in a block 11a to slide in a slot 12 towards the spigot or shaft 8 by the force of a spring 14. Means for controlling movement of the bearings comprises a cam 17 pivoted on the plate 3 acting through rollers 18 upon bevellededge portions of the plates 15 and having an arm 19 engageable with an extension finger 20 on one limb 21 of a fork of the machine handle. By movement of the handle 13 the wheels can thus be brought into and out of engagement with the shaft 8. Each brush 1 is mounted so as to permit it to rock slightly from its normal horizontal position by having a flat leaf spring 24 with bent-upwings received in a recess 26 in the brush body 1a. The leaf spring 24 as well as a small driving plate 27 engaging with reinforced shoulders projecting into the recess 26 to drive the brush are held on the spindle 9 by a screw which also serves to secure a fastening clip 29 whereby a felt pad may be held in position by a press stud. A spring-loaded cam 23 on the handle fork 21 is made to actuate a motor switch 22 to switch the motor on after the brushes 2 are brought into driving engagement with the shaft 8 on moving the handle to its working position and vice-versa.
