Abstract: 1,142,286. Lubricating. SACHSENRING AUTOMOBILWERKE ZWICKAU VEB. 10 March, 1967, No. 11298/67. Heading F2A. [Also in Division F1] A lubricant-pump 2 supplying lubricant to the fuel-air mixture of an internal combustion engine of a vehicle is combined with a deliverypump 1 which serves the steering, clutch, brake or suspension of the vehicle, the lubricant in the lubricant pump 2 being heated by means of heat transmitted from the pressure-medium of the delivery-pump 1. The casing of the latter is in contact with the casing of the lubricant pump 2 and a common shaft 3 is rotated by the engine (not shown), via a coupling 4. Thus a gear 5 of the delivery-pump 1 drives a gearwheel 7 which is on a stub-shaft 8 and pressure medium is delivered to the steering &c. A worm 9 on the shaft 3 drives a wormwheel 10 which is mounted on a piston 11 of the lubricant-pump 2. The piston rotates to effect valve action and is reciprocated by means not shown. Lubricant is supplied to a chamber 14 of the pump 2, via a feed-pipe 12 and bores 13, and passes from the chamber 14 to the piston 11 via a passage 17. Alternatively, the chamber 14 may be by-passed and lubricant may be supplied direct to the piston 11, via a feed-passage 18, Fig. 3. In use, the pumping action of the delivery-pump 1 causes heat to be produced in the pressure medium. The latter flows through passages 15 and 16 in the lubricant-pump 2 and supplies heat to either the lubricant in the chamber 14 or to the lubricant flowing through the feed-passage 18.

Title: Improved means for controlling the pattern mechanism of high speed drop box looms
IPC: D03C1/36
Filed: 1925-05-02
Abstract: 254,448. Livesey, A. May 2, 1925. Change-box motions.-The drop boxes are controlled by a rod A connected by a spring a to a rod A<1> on a lever B, which is operated by a connecting rod C from a crank C<1> on the stud of a toothed dog wheel D<1>. This is turned to change the boxes by the teeth e of a gear wheel E rotating with but slidable on the tappet shaft E<1>, the wheel E being moved into position to engage the dog wheel D<1> by a bell crank lever M<1> operated by a rod M from an indicator lever K. This lever is pivoted on the end l of a lever L, which is pivoted on a projection or stud l<1> carried by the loom frame. A runner on the lever L rests on a member g<1> on a frame G or lever carrying the stud of a pattern disc or wheel H. The frame &c. G is raised by a cam on the tappet shaft, and if a peg on the wheel H is in position under the lever K it operates this lever, whereby the rod M and lever M<1> are operated against spring action and the boxes are changed. A pawl i mounted on the loom frame normally engages a ratchet wheel h rotating with the wheel &c. H, so that this is rotated at each reciprocation of the frame &c. G, but when the end of the pattern is reached and plain weaving is to occur,. one of a number of pins &c. on a second disc or spider wheel H<1> rotating with the wheel H operates a detector lever K<1>, a rod n, a lever N and a rod D, which lifts the tail of the pawl i,. thus stopping the rotation of the pattern wheel &c. H. The loom then weaves plain cloth until the pawl i is released. When the lever N is operated to stop the rotation of the wheel &c. H, a pin n<2> thereon is raised out of a hole in the. periphery of a spring-controlled friction disc P, thus enabling this disc to be rotated frictionally by a disc P<1> on a shaft driven by worm gearing from the take-up roller. the pin &c. n' now bears against the periphery of the disc P and prevents the lever N from returning to normal position when the frame &c. G next descends. When, however, the next hole in the disc P comes into position beneath the pin n<2>, the lever N falls, the pawl i is released and the rotation of the pattern wheel &c. H is restarted, the rotation of the disc P being stopped. The friction disc P is interchangeable for other discs. The rod D is preferably connected by lever mechanism r, R, r<1> to the knock-off handle of the loom, so that the pawl i will be disengaged immediately the loom is stopped. A modification is described wherein a card barrel and cards are used, the barrel being mounted on a stationary part of the loom frame and the indicator levers being mounted at the top of a lever contolled by a cam on the tappet shaft. The lever carries a third lever, which is pivoted to the loom frame and carries the pawl for rotating the card barrel. A modification is also described relating to drop boxes for more than two shuttles.

Title: Manufacture of cyanine dyes, and their use in modifying the properties of photographic emulsions
IPC: C09B23/04
Filed: 1936-04-24
Abstract: Photographic gelatino-silver halide emulsions are sensitized by means of dyestuffs containing a benzthiazine nucleus and having the formula <FORM:0478945/IV/1> or <FORM:0478945/IV/2> where A = H or alkyl, D = vinylene or phenylene, R and R1 = organic residues, X = an acid radicle, Y =--CH2--S-- or --S--CH2-- and Z = the non-metallic atoms necessary to complete a heterocyclic nucleus.  Thus R and R1 may be methyl, ethyl, n-butyl, decyl, allyl, or benzyl, X may be halide, alkylsulphate, perchlorate, or p-toluene sulphonate and Z may represent the atoms necessary to complete a 5-membered heterocyclic nucleus, e.g. an oxazole, thiazole, selenazole, indolenine, thiazoline, selenazoline or a 6-membered heterocyclic nucleus, e.g. pyridine or quinoline.  The dyes are obtained by condensing a quaternary salt of a 3-alkylthiol derivative of a 2 : 4-or 1 : 4-benzthiazine with a cyclammonium quaternary salt containing a reactive alkyl group in the a - or g -position.  Instead of the salts and the respective bases and alkyl salts may be used.  A basic condensation agent may be added. In the examples: (1) - (6) 3-methylthiol-2 : 4-benzthiazine is fused with ethyl-p-toluenesulphonate and 1-methylbenzthiazole, quinaldine, 1-methylbenzselenazole, 1 - methyl - 5 : 6 - benzbenzthiazole, 1-methyl3 : 4-benzbenzoxazole or 2-methylthiazoline; the reaction mass is dissolved in alcohol, in some cases refluxed with triethylamine to complete the condensation, and the dye precipitated with potassium iodide, (7) 3-methylthiol - 1 : 4 - benzthiazine, 1-methylbenzthiazole and methyl-p-toluenesulphonate are heated together and the dye precipitated as above.  A sample has been furnished under Sect. 2 (5) of the dyestuff made by condensing 3 - ethylthiol - 2 : 4 - benzthiazine methiodide and 1-ethylbenzthiazole ethiodide in alcohol in presence of triethylamine.  The dyes are added to the emulsions so that the concentration of dye is 10--20 mg./litre of emulsion.  3 - Methylthiol - 2 : 4 - benzthiazine is made by electrolytic reduction of anthranilic acid to o-aminobenzyl alcohol, treating the latter with alcoholic potassium hydroxide and carbon disulphide to form 3-thiol-2 : 4-benzthiazine and methylation. The quaternary salts are made e.g. by heating with methyl iodide or sulphate.  3 - Methylthiol - 1 : 4 - benzthiazine is made by reduction of o-nitrophenylthioglycollic acid to 3-ketodihydro-1 : 4-benzthiazine, treating the latter with phosphorus pentasulphide in boiling xylene and methylating.

Filed: 1944-06-19
Abstract: 645,331. Compression and tension resistances. GALL. D. C. June 19, 1944, No. 11668. [Class 37] [Also in Group XXII] A resistance strain gauge comprising a length of wire formed into a grid of parallel runs is produced from a length of wire 1, held at a constant tension by a spring-urged hook 16 by drawing the wire out into loops between stationary hooks 25 by hooks 34 which are moved back one at a time to form the grid 1a to 1f (see Fig. 9). At this stage an internally-heated platform 38 is raised to bring a base 2 into contact with grid and cement is applied and allowed to set and so to secure the grid to the base. Hooks 25, 34 are raised free from the wire which is cut near the outside edges of hooks 18, 19 to leave the grid ready for attachment, of the terminal strips (not shown) which are further secured by cement to the base 2. The base 2 may be a continuous strip (see Fig. 5), and is fed from a roller (not shown) through a guide tube 37, I over the platform 38 and then, with the grids attached, through a further guide tube 48 to the front of the machine. The hooks 25, 34 are respectively attached to blocks 24, 30 which are pivoted on axles 23, 29. The raising and lowering of the blocks 24, 30 is by the horizontal movement of rods 55, 59 and their associated coupling components 53, 54 ; 57, 58. The downward movement of the block 24 causes a pecker 49 to grip the base strip 2 in tube 37 against a guide 51 and move it forward by an amount equal to the overall length of a complete grid. Platform 38 is raised by a cam 41 and rod 39 device operated by rotation of knob 45a, a number of similar devices shown in Fig. 5 may be mounted side by side, all being fed with wire from a common reel.
