Filed: 1922-12-28
Abstract: 201,847. Heute, A. Dec. 28, 1922. Soles, machines for. - The rollers 1, 2 of a machine for rolling leather are mounted in a frame of such a construction as to constitute a projecting casing for the operating-mechanism, and at the foot of the frame a drawer is provided for the storage of leather, tools, &c. The frame may be constructed as shown in Figs. 1 and 2, of a pair of suitably-bent angle-iron members 12, 13 secured together by bolts 30 which also serve for holding facing plates 16 - - 19 that stiffen the frame and also act as a guard for the rollers; a gap is left between the plates to allow the leather to be fed to the rollers, and the edges of the plates below the gap may be bent outwardly to form tables for feeding and receiving the leather. At the lower part the frame members are spaced outwardly so as to form a base for the machine, and in the space so formed the drawer 25 is fitted. A space for a tray 27 is left immediately below the lower roller 1. The latter is mounted in fixed bearings, 15, and the upper roller 2 in movable bearings 7, which are pressed downwardly by the loading screw 3 acting through levers 4, the enlarged heads 5 of which act between fixed abutments 6 and the upper bearings 7. The gears 8, 9 at the sides of the frame are protested by casings 20, 21. In the construction shown in Figs. 4, 5 and 6, the angle-iron members are dispensed with, and the frame is constructed from a pair of members 30, 31, pressed as shown and connected together by bolts passing through the fixed bearings 15, the abutments 6, and the block for the loading screw 3, and to stiffen the frame, webs 36 are bent outwardly at the sides; in the spaces left by these webs, the gears 8, 9 are fitted, being protected by casings 20, 21.

Title: Improvements in or relating to the measurement of wall thickness of metallic articles
Inventor: WELLS RALPH WESTON
IPC: G01B7/06
Filed: 1956-11-20
Abstract: 840,552. Electric tests. BRITISH INSULATED CALLENDER'S CABLES Ltd. Nov. 19,1957 [Nov. 20,1956], No. 35518/56. Class 37. The wall thickness of metal articles, such as sheet-strip, tubing and cable sheaths 3, is determined by passing a constant current through the wall from electrodes 3 so that a magnetic field is produced, and adjusting the height of a conductor 4 in series with the sheet path so that the resultant magnetic field, as detected by a ferrite-cored coil 6 is zero. The height of the conductor as measured on the adjusting screw 11 is a measure of wall thickness. An alternating supply is used and the coil is tuned to the A.C. frequency by capacitor 7. The contact members are held in a frame 5 of heat and electrical insulating material which also supports the coil 6. In an alternative arrangement (not shown) the field is arranged to deflect the electron path in a triode valve the heater of which is fed with A.C. and the grid of which consists of a slotted plate through which the electrons pass. Thus the output is a series of " squarish " pulses.

Title: Binary full addersubstractors

Filed: 1971-07-29
Abstract: 1364281 Binary adder/subtractor TOKYO SHIBAURA ELECTRIC CO Ltd 29 July 1971 [31 July 1970] 35635/71 Heading G4A A binary full adder/subtractor stage comprises three logic units 30, 40, 50 interconnected as shown (Fig. 4). The first unit 30 receives only the two digits A, B to be added or subtracted and gives an output R according to the equation: The second unit 40 receives the output R of the first unit and the carry-in (or borrow) signal C n-1  and produces the answer A according to the equation: The third unit 50 receives the inputs of both the first and second units as well as an input O determining whether the stage is to add or subtract and produces a carry-out signal C n  according to the equation: Each logic unit 30, 40, 50 comprises a complementary circuit of P- and N-channel insulated gate field effect transistors and therefore draws negligible current except when switching; it is thus suitable for physically small integrated circuits for use in table top computers. Each of the first and second logic units 30, 40 comprise a pair of switching circuits 30c, 30e, and 40c, 40e connected between the supply conductors, one of the pair being conductive when its inputs are in a like state and one being conductive when its inputs differ. The third logic unit 50 comprises a mixture of AND and OR gates. Some transistors (e.g. 51, 56) serve dual functions but may be duplicated, e.g. as in Fig. 7 (not shown) which shows an alternative circuit operating according to different but equivalent equations.

Title: Improvements in treating textiles and oils therefor
Filed: 1936-10-30
Abstract: Textiles consisting of or containing animal hairs, e.g. wool, mohair, angora, shoddy, alone or mixed or with silk, rayon, cotton, are oiled, subjected to one or more textile processes, and scoured, the oil consisting of an ester or mixture of esters as defined with or without a diluent, the viscosity being between 200 and 650 seconds Redwood at 60 DEG  C.  The esters are such fully esterified liquid synthetic esters of the following groups as have specified properties: (1) ester formed from a monohydric alcohol and an unsaturated acid, polymerized and/or oxidized; (2) ester formed from a monohydric alcohol, and a polymerized and/or oxidized unsaturated fatty acid, the acid may be polymerized and/or oxidized as such or as an ester which is then hydrolyzed; (3) ester formed from a di- or a tri-glycol and an acid as in (2); (4) ester formed from a di- or a tri-glycol and a saturated or an unsaturated fatty acid; in all cases the acids contain 8 or more carbon atoms.  A "polymerized and/or oxidized" ester or acid is one which has been heated with or without access of air with polymerization, oxidation, or both, has been effected.  The specified properties are: the ester (1) must not oxidize much more easily than olive oil (as used for textile purposes); (2) is substantially insoluble in water; (3) does not disperse in water by simple agitation; (4) can be removed by scouring in soap solution with or without alkali.  The esters may be used alone, or in aqueous emulsion, or in admixture with a diluent which may be of higher or lower viscosity, e.g. petroleum jelly, polymerized rape oil, a thin mineral oil, or a thin ester.  The example given is an oxidized and slightly polymerized methyl cyclohexanol oleate, iodine value 51; this may be emulsified with soap solution, or with Twitchell base, to form a "wool cream" requiring dilution before use.  Components specified for the different groups of esters are: alcohols-for groups 1 and 2, hexyl, lauryl, cetyl, cholesterol, methyl cyclohexanol, ethyl; for groups 3 and 4, di- or triethylene and propylene glycols; acids-for groups 1, 2 and 3, mono- and di-ethenoid fatty acids, and simple substitutive producer; for group 4, mono-ethenoid and saturated fatty acids, e.g. oleic, stearic, and oxidized or hydrogenated di-ethenoid fatty acids, and simple substitution products, e.g. dihydroxy-stearic acid.
