Title: Improvements in or relating to the isolation of piperazine
IPC: C07D295/023
Filed: 1945-04-13
Abstract: Piperazine is isolated in the form of its hydrohalide/ammonium halide double salt from an aqueous solution containing a piperazine hydrohalide by adding to the heated solution a quantity of an ammonium halide in excess of the stoichiometric amount (relative to the piperazine hydrohalide), cooling and separating from the solution the resulting precipitate of the piperazine hydrohalide-ammonium halide double salt.  The solution so treated is advantageously one containing a piperazine hydrohalide mixed with hydrohalides of other organic bases with or without mineral salts, or one obtained by the conversion of diphenyl piperazine into the nitroso compound, followed by treatment with bisulphite and hydrolysed in an acid medium, or by the method disclosed in Specification 595,430.  In examples: (1) a mixture containing 181 parts piperazine hydrochloride (obtained by the method of Specification 595,430) is dissolved in 1000 parts water and the warmed solution is treated with 200 parts ammonium chloride and thereafter cooled to precipitate the double salt; (2) a solution of piperazine (obtained from diphenyl piperazine via its nitroso compound) is concentrated, freed from precipitated salts, treated with concentrated ammonia to bring the pH to 2 and then with ammonium chloride to precipitate the double salt.  A sample has been furnished under Sect. 2 (5) of the double salt of piperazine hydrobromide and ammonium bromide, obtained by p  neutralizing an aqueous solution of piperazine hydrate with aqueous hydrobromic acid and by adding to the warmed solution ammonium bromide, followed by cooling.

Title: Apparatus for measuring forces
Filed: 1959-03-18
Abstract: 856,504. Weighing apparatus. BARTELT ENGINEERING CO. March 18, 1959 [March 26, 1958], No. 9416/59. Class 143 [Also in Group XIX] A' force-measuring device comprises a cantilever spring supported on a base with a rigid member dis- - posed adjacent the free end of the spring in a plane transverse to the longitudinal axis of the spring, the rigid member being in connection with the spring and resiliently supported by the base in such a way that movement of the member with deflection of the spring under load is confined to a single direction transverse to the longitudinal axis of the spring. The invention is described with reference to a weighing apparatus whose load-supporting platform 10 (Fig. 2) is attached to the rigid member 23 of the device. This member comprises an apertured rectangular plate disposed in a vertical plane adjacent the free end of the horizontal cantilever spring 13. The resilient supporting means for the member 23 consists of flat springs 28 connecting the four corners of the member 23 to the casing 12 of the apparatus by means of the arrangement shown in Fig. 4. The free end of the cantilever is connected to the rigid member by a wire 39. The casing 12 enclosing the device is fitted with an inlet 62 for the admission of air under pressure which escapes through the aperture 27 through which the connection between the rigid member 23 and the load platform 10 extends, thereby excluding dirt. The casing also supports an hydraulic damper 53. Indicating means. The free end of the cantilever 13 carries the armature 20 of an electromagnetic transducer 19 of conventional type for recording the displacement of its end. Temperature compensation. Those parts of the device which extend transversely to the cantilever's longitudinal axis all have substantially the same coefficient of thermal expansion as each other and those extending parallel to the cantilever are made to have the same coefficient of expansion as the cantilever. The circulation of the compressed air in the casing also serves to reduce temperature gradients within the apparatus. The electromagnetic indicating transducer is also constructed to avoid errors due to temperature changes, being constructed so that the non-magnetic frame of the transducer has the same expansibility as the magnetic core thereof and arranged so that the whole construction is symmetrical about the gap in which the armature 20 moves.

Title: Improvements in or relating to mechanical catalysis
IPC: C07F3/02
Filed: 1943-06-11
Abstract: <PICT:0571539/IV/1> Chemical reactions involving a solid and a liquid or gas are facilitated by cutting chips from a mass of the solid and exposing the new surfaces as they are formed to the action of the fluid reagent.  The local heat and pressure generated at the point of cutting accelerate the reaction.  Suitable apparatus comprises a cylindrical reaction chamber 10 in which rotates a shaft 5 carrying a cutting blade 8, against which a rod 16 of the solid reagent is slowly advanced by a screw 23.  The chamber is supplied with gas inlet and outlet pipes 27, 31, a liquid inlet pipe 33 and an outlet pipe 36 for the reaction products.  It is surrounded by a passage with connections 39, 41 for the circulation of a heating or cooling fluid.  The invention is particularly applicable to reactions between metals and organic liquids.  For example, hexachlorethane is obtained by cutting chips off an aluminium rod in a body of carbon tetrachloride near its boiling point, in an atmosphere of nitrogen. The chips may be cut at such a rate that they are immediately consumed, or at a greater rate, in which case the reaction proceeds autocatalytically after the mixture has left the reaction chamber. In another example, a Grignard reagent is prepared by cutting chips of magnesium in an ether solution of phenyl bromide.  The phenyl magnesium bromide formed is hydrolysed or reacted with other compounds, e.g. with ethylene oxide to produce benzyl carbinol. Reactions of the Barbier type may also be effected, e.g. magnesium may be cut in presence of a mixture of ether, phenyl bromide, and water to form benzene and other products.

Abstract: 708,001. Shuttleless smallware looms weaving two fabrics;, beat-up motions. CROMPTON & KNOWLES LOOM WORKS. April 24, 1951 [May 5, 1950], No. 9550/51. Class 142(2) Two fabrics are woven, one above the other, in a small ware loom in which loops of weft, interknitted at the selvedges, are inserted from opposite sides alternately by needles actuated by a continuously-rotating comb. Weft inserting mechanism, Figs. 4 and 23. A pair of needle carriers 55, 70 are oscillated about floating pivots 63, 63a which are linked to arms 42, 43, themselves coupled together by a link 76; oppositelyrotating cranks 50, 69 oscillate the carriers, and a crank (not shown), running at halfspeed, swings the pivots 63, 63a from side to side. When the pivots are performing the left-hand part of their travel, needles 71, 72 on the carrier 70 follow the path a. Fig. 23, to lay wefts in the two fabrics; needles 58, 59 on the carrier 55 at the sametime enter and leave the sheds along the path b without laying any weft. When the pivots 63, 63a are in the right-hand part of their travel, the needles 58, 59 lay weft, and the needles 71, 72 make an ineffective stroke. Forming selvedges, Fig. 27. As a weftinserting needle emerges from the far side of the shed, the weft thread W rides up a deflector 155 to ensure engagement by a knitting needle 140, which is disposed (though not so shown on Fig. 27) with its hook and latch pointing slightly downwards; the needle draws the loop of weft through the preceding loop (not shown) on the shank of the needle, this loop being thereby cast off. A nylon bristle 158 prevents the latch 101 from, swinging shut. when the needle moves to take a fresh loop. Beat-up motion, Fig. 8. The weft in both fabrics is beaten up by peaks e, f on continuously rotating comb blades d whose minimum radial dimension is such that they never emerge from the warp even when the sheds are open.

Abstract: 740,226. Sliding-clasp fasteners. TALON, Inc. April 1, 1954 [April 20, 1953], No. 9568/54. Class 44. A slide fastener slider comprises overlying spaced wings 2 and 3, means detachably connecting the wings together at one end thereof including an inwardly extending portion 6 carried by one of the wings which cooperates with and engages a corresponding inwardly extending portion 7 carried by the other wing, a movable latch member 10 pivotally attached to one of the wings adjacent the inter-engaging portions, the latch member being arranged in a recess 9 in the first wing and extending up through a recess in the other wing to a point above the surface of this wing and an enlarged portion arranged on the outer free end of the latch member above the surface referred to, the enlarged portion 14 having means co-operating with that surface for maintaining the wings in their proper spaced operating relation and for permitting the wings to be moved apart to another predetermined spaced position. As shown, the inter-engaging portions 6 and 7 are formed with polygonalshaped inter-engaging surfaces to prevent relative rotation of the wings 2 and 3. The latch member 10 pivoted to the wing 3 and extending through an aperture 13 in the wing 2 is provided with a head portion 14, projecting beyond the wing 2, having on each side thereof a cam portion 15 which co-operates with a pair of side-by-side recesses 16 and 17, on the outer surface of the wing 2, the recess 16 being shallower than the recess 17. A pull member 20 is pivoted at 19 to the wing 2 and is provided with a recess 21. A spring 24 biases the latch member 10 into engagement with the recesses 16 corresponding to the normal spacing of the wing members 2 and 3. If, however, material or foreign matter are caught between the wings and the fastener elements, the wings are moved apart to free the slider by operation of the pull member 20 to its uppermost position so that a wall 22 of the recess 21 bears against a face 18 of the latch member 10 and moves the latter into engagement with the recesses 17 against the spring 24. Upon release of the pull member, the wings 2 and 3 are automatically returned to the position shown.

Title: Improvements in or relating to electrical measuring bridges
IPC: G01R17/00
Filed: 1954-04-02
Abstract: 766,567. Measuring bridges. WAYNE KERR LABORATORIES, Ltd., and CALVERT, R. April 4, 1955 [April 2, 1954], No. 9683/54. Class 37. A radio frequency impedance measuring bridge comprises a pair of inductive ratio arms formed by two windings of a common core, having a third R.F. energized winding exciting the bridge, and an unbalance detector energized through an output winding connected at one end to the ratio arm junction and connected at the other end through the unknown impedance to a point on one ratio arm remote from the junction thereof; the input of an adjustable attenuator network being connected across the other ratio arm to provide an adjustable output voltage applied through a standard resistance to the output winding. An input transformer 11 is excited at, e.g., 100 mc/s. over winding 12 and has two ratio arm secondary windings 13, 14, of which 14 is variably tapped, whose junction is connected over line 15 and through the primary 16 of output transformer 17 (energizing phasesensitive detector 19) and the unkown impedance 9, 10 to the free end of winding 13. The adjustable tap of winding 14 is connected to the input of an adjustable ladder attenuator 21 energizing potentiometer 22 whose variable tap is connected through adjustable standard resistance 24 to the unknown impedance end of primary 16, which is also connected through adjustable standard reactance 25 to the tapping 20 of winding 14. Resistance 24 and tapping 20 may be fixed, while winding 13 may be variably tapped and the standard reactance connected to adjustable taps on winding 16. The line 15 may also be variably tapped to a point on winding 16. At balance the reactive and non-reactive currents flowing in winding 16 through the unknown impedance 9, 10 are respectively balanced by the reactive current flowing directly through standard impedance 25 and from the attenuator through standard resistance 24, whereby the reactive impedance component is calculable from the turns ratio of the ratio arms, the value of reactance 25, and the setting of the tap 20; and the non-reactive component is calculable from the turns ratio of the ratio arms, the setting of tap 20, the setting of the attenuator, and the value of resistance 24. The measurement of the R.F. values of inductive and resistive impedances of a coil enables its Q to be determined.
