Abstract: 119,483. Morison, D. B. June 29, 1917. Aspirating apparatus, ejector, for the extraction of air and vapour from steam-condensers of the multiple-stage class wherein the first stage consists in a plurality of jets in parallel each functioning in connexion with its own combining tube, and consists in the combination therewith of a second-stage ejector around the axis of which the ejectors of the first stage are arranged, the discharge from these ejectors being around or forming an annulus around the inducing-fluid nozzle of the second stage, so as to convey the discharged fluid thereto for further compression. The first stage nozzles x, Fig. 1, have a common suction-chamber r, with condenser connexion y, and are supplied from a common supply chamber t situated at a little distance in order to avoid heating effects. The first stage combining-tubes g are at first circular in section, but eventually widen out as passages e so that they can enter without sudden change of shape an annular chamber surrounding the central inducing-fluid nozzle v of the second stage, which is supplied with steam through a pipe l from a chamber m. Fig. 5 shows in two sections the gradual change in shape of the passages e, and the approach of their radial bounding-walls p, which ultimately coalesce, and end in sharp edges. According to a modification the combining-tubes g may be continued into the combining-tube h of the second stage, Multiple-stage ejectors, according to this invention, may be employed as the air-withdrawing and controlling ejectors of the three-stage system described in Specification 8335/15, the third ejecting stage being constituted by a steam or water operated ejector or a mechanical airpump, with or without intermediate receivers.

Abstract: 757,387. Drawing arrangements for spinning machines. HARBECK, M., STEFFEN, H. W., STEFFEN, E., and HARBECK, M., [trading as HEIDENREICH & HARBECK.]. April 7, 1953 [April 9, 1952; Jan. 9, 1953], No. 9425/53. Class 120 (2). A spinning frame for bast and leaf fibres has a drawing device comprising a pair of belts located between feed and delivery rollers, one of the belts being partially supported by a roller adjacent the delivery rollers and mounted on a pivoted lever. A feed roller 2 is preferably mounted on a driving shaft 1 with which it is coupled for normal operation, but from which it is disconnected upon actuation of a stop motion by a thread feeler lever 34. Simultaneously with the stopping of the roller 2 on thread breakage, belt-supporting rollers 25, 29, which are geared to it, are stopped also. The lower belt 22 is carried by rollers 25, 26 and the upper belt 23 by rollers 29, 30, the two latter being staggered. Roller 30 is mounted on the end of a lever 32 suspended from a pivot 33 and adjustable by means of a rod 41. Also suspended from the pivot 33 is a curved arm 39 arranged to press the belts 22, 23 together. A feed pressure roller 11 is loaded by a spring 13 and a delivery pressure roller 16 is loaded by a spring 17 acting through a lever 51 held in position by a lever 47 having a cam surface 48. The spring 17 also serves to urge a roller 21 against a roller 20. In another embodiment, Fig. 4, an upper apron roller 59 is mounted on a lever 72 carried by a pivot 61, that also carries a curved arm 60 arranged to press belts 56, 57 together by means of an adjustable spring 75. The belts 56, 57 are also urged together by the resilient down-turned ends 76 of a number of rods 63 suspended from a pivot 65. A slide-member 64 may serve to adjust the pressure of the rods 63. Reference has been directed by the Comptroller to Specifications 516,466 and 731,868.

IPC: F16H61/46
Filed: 1964-03-06
Abstract: 986,630. Hydrostatic transmissions. SPERRY RAND CORPORATION. March 6, 1964 [April 5, 1963], No. 9501/64. Headings F2C and F2D. [Also in Division G3] In a hydrostatic transmission, the pump 10, which may be of the rotary cylinder, reciprocating piston type as described in Specification 754,836, has its displacement automatically controlled in accordance with delivery pressure by a tilting yoke 26 operated by a piston and cylinder servo actuator 30 controlled by a regulating valve 40. The latter has ports 44, 46, 48 respectively connected by pipe-lines 50, 52, 54 to the pump outlet, the actuator 30, and to exhaust, and a spool element 66 with lands 68, 70 controlling communication between the ports 44, 46 and ports 46, 48 respectively. The spool is loaded by a spring 80 and a smaller diameter sensing valve member 74 is mounted between the spring and spool, the member 74 being subjected to the pressure in a chamber 76 formed by the interior of the valve housing 42 and the interior space 78 of a screwed-in end cap 58. A longitudinal passage 86 having a sharp edged restriction 90 establishes communication between chamber 76 and pressure port 44. In the normal spring- biased position the valve spool 66 is urged to the right against an end stop 82, the land 68 isolating port 44 from port 46 and land 70 permitting communication between ports 46 and 48. As the pump delivery pressure increases a point is reached when this pressure acting on the right-hand end face of spool 66 overcomes the combined force of spring 80 and that due to the pressure in chamber 76 acting on sensing element 74, to allow land 68 to open communication between ports 44, 46 to pass pressure liquid to actuator 30 and thus reduce the pump displacement. The loading of spring 80 may be varied by an adjusting screw 84 passing through end cap 58, and the volume of chamber 76 may be altered by adjusting the axial setting of end cap 58 or by replacing the latter with one having a different internal liquid volume 78. Details of suitable operating parameters expressed in terms of the valve areas, spring rating and liquid bulk modulus are given.

Abstract: 1,088,537. Arc welding systems. WESTING- HOUSE ELECTRIC CORPORATION. March 8, 1965 [April 7, 1964], No. 9723/65. Heading H2H. An arrangement for providing a welding current which tapers according to a prearranged pattern to give crater-free welds comprises a bank of resistors 1R-5R with selector switches 1CB-5CB, contacts 1CRa- 5CRa operated from cams 1CW-5CW motivated by a timer motor TSW, and a variable resistor VR motivated by a motor M2. Preparatory to welding, selected ones of switches 1cB &c. are closed and VR set to zero, and the welding operation is commenced. Near the end of the operation switch SW2 is reversed to energize a relay 8cR which energizes a motor M2 to increase the resistance of VR decreasing the welding current until at some position a limit switch 2LS on its shaft de-energizes relays 1CR-5CR increasing the circuit resistance resulting in a sudden drop in welding current. Resistor VR continues to increase until limit switch 1LS is operated opening contactor M, which terminates the welding current. When it is desired to terminate the welding current in steps, timer TSW may be operated so that cams 1CM-5CM open switches 1CW-5CW in a predetermined sequence. The rise of welding current may be controlled in a like manner by controlling relays 1CR-5CR from a sequential controller.

Title: A novel trialkenyl boron and the production of citronellol therefrom
IPC: C07F5/02
Filed: 1961-03-17
Abstract: The invention comprises tricitronellyl boron, which may be made by treating 2,6-dimethyl-2,7-octadiene with diborane. The diborane can be employed as a gas or generated in situ, e.g., by treatment of sodium or lithium borohydride, sodium trimethoxy borohydride, or sodium or lithium hydride with boron trifluoride etherate, or from anhydrous aluminium chloride and sodium borohydride.  Suitable solvents are diglyme, dioxane and tetrahydrofuran.  The reaction may be carried out at temperatures between 0 DEG  and 160 DEG C., preferably at room temperature or slightly above.  The resulting tricitronellyl boron can be oxidized and then hydrolysed in an aqueous medium to form citronellol. Oxidizing agents such as hydrogen peroxide, oxygen, nitric acid and alkaline potassium permanganate may be used. Hydrogen peroxide may be used in aqueous alkaline solution to accomplish the oxidation and hydrolysis, or the hydrolysis of the intermediate trialkenyl borate may be effected with water or dilute acids. The 2,6-dimethyl -2,7-octadiene may be obtained by hydrogenation of turpentine with a Raney nickel catalyst to give pinane which is thereafter pyrolyzed in the presence of a mildly acidic catalyst at 400 DEG  to 700 DEG C. to yield a mixture from which the desired diene is recovered by fractional distillation. By using a diene made from optically active pinane from American turpentine, an optically active citronellol is obtained. This can be dehydrogenated to optically active citronellol which is cyclized to isopulegol and the latter hydrogenated to optically active 1-methanol.
