Title: Process for desiccant drier regeneration
IPC: C08F2/00
Filed: 1973-06-27
Abstract: 1417742 Dessicant regeneration in olefin copolymerization EXXON RESEARCH & ENG CO 27 June 1973 [13 July 1972] 30508/73 Heading C3P An ethylene-α-olefin copolymerization process in which the steps of (a) diluent purification and recycle and (b) regeneration of the dessicant drier used to dehydrate the α-olefin monomer feed, using a portion of the dry recycle diluent, are integrated into the copolymerization procedure. In this manner, the diluent employed for regeneration is returned to the purification zone (a) after removal of water from the drier. Ziegler catalysts are used in the copolymerization. The diluent used in regeneration may be a vapour or liquid. In the former case a further step of cooling the drier may be necessary, e.g. by passage of dry liquid diluent therethrough. It is also preferred to flush the drier with α- ol'efin vapour prior to regeneration, to remove residual liquid monomer therefrom. The polymerization is preferable applied to ethyl'enepropyl'ene-non-conjugated diene terpolymerization. Aluminium oxide is mentioned as the dessicant.

[Class 44] A door latch, particularly for vehicle doors, of the kind in which the spring loaded latch bolt is retracted by a member operable by inside and outside handles and also disengageable from the bolt by the inside handle to render the outside handle inoperative, comprises the combination of a supporting plate a formed with a cam slot k, a peg h<1> movable by the inside handle along the cam slot k and passing through a slot i' in the bolt retracting member d, and another peg h attached to the plate a and passing through another slot i in the bolt retracting member. The movable peg h' is carried by a link j operated by the inside handle, and movement of the link in one direction pulls back the member d and so retracts the bolf b by engaging the shoulder f, while movement in the other direction causes the peg h<1> to move down into the inclined part of the slot k and tilting the front of the member d downwardly so that the lug g thereon clears the shoulder f. The outside handle, which in the construction shown is movable about a vertical pivot, is arranged to operate the member d by contact with the front of the lug g.

Abstract: 543,308. Synthetic resins. STANDARD OIL DEVELOPMENT CO. Nov. 28, 1939, No. 31010. Convention date, Dec. 31, 1938. Addition to 513,521 and 523,248. [Class 2 (iii)] In a process of preparing co-polymers having a molecular weight above 800 ty the treatment of an alipiiatic mono-iso-olefine, e.g. isobutylene or 2-methyl butene-1, and a hydrocarbon having a conjugated system of alternate double and single bonds and containing at least one olefinic linkage, e.g. 1. 3- butadiene, isoprene or styrene, with a Friedel-Crafts catalyst at a temperature below 0‹C., the catalyst is employed in the form of a solution or dispersion in an inert organic liquid and is fed into the reaction mixture in the form of fine drops having a volume of not more than 0.01 c.c. The catalyst solution or dispersion may be forced under pressure through a straight or conical orifice or through a porous thimble, or may be sucked up by a gas such as nitrogen under pressure and ejected through a nozzle. The low temperature may be produced by carrying out the reaction in the presence of a liquefied normally gaseous hydrocarbon such as liquefied ethylene, propane or butane, which acts as a solvent or diluent and also as a refrigerant, or by the addition to the reactants of an inert normally gaseous material such as solid carbon dioxide, if desired in the presence of a low molecular weight hydrocarbon such as ethane, propane or a refined saturated fraction of naphtha as a solvent or diluent. Suitable catalysts are aluminium chloride or bromide and titanium tetrachloride dissolved or dispersed in an inert organic liquid haying a freezing point not more than 20‹ C. above the desired polymerization temperature, e.g. alkyl halides such as methyl-, ethyl- or isopropyl chloride, chloroform and carbon disulphide. The catalyst solution may be cooled externally or by the addition of solid carbon dioxide.

Title: Improvements relating to power supply systems
IPC: H02J7/14
Filed: 1963-08-07
Abstract: 1,045,287. Automatic voltage control. ROBERT BOSCH G. m. b. H. Aug. 7, 1963 [Aug. 8, 1962], No. 31084/63. Heading G3R. A voltage regulator for a permanent magnet alternator having a rectified output for connection to a battery comprises a controllable semi-conductor which carries the load current and which is controlled in dependence upon the output voltage. As shown, a three-phase alternator A having a permanent-magnet field F supplies a battery B over rectifiers 13, 14 and 15, a power transistor 16, positive lead 18 and negative lead 17. When the output voltage is below a pre-determined value, e.g. 13V, transistor 16 is conductive by virtue of a base/emitter voltage derived from a voltage divider 23, 24; any increase in this pre-determined value operates a relay 20 connected across the leads 17,18 by a switch 19 which is closed in its operative position, whereby the relay contacts 21, 22 are closed to short circuit the base/emitter path of the transistor 16 which is then cut off. When the battery voltage subsequently drops below a lower limit e.g. 12. 8V, the relay 20 is de-energized and the control cycle starts again. In a modification (Fig. 2, not shown), the switching of the power transistor 16 is effected by a blocking oscillator comprising a feedback transformer and a control transistor responsive to the output voltage. In another embodiment (Fig. 4, not shown), each winding of the three-phase alternator is connected in series with an individual transistor, the three transistors being controlled by a common blocking oscillator.

An axial-flow pump comprises an impeller chamber which is open in axially opposite positions, the annular rear opening being connected to a substantially semi-toroidal annular chamber to deflect the flow through about 180 degrees and direct it in countercurrent to the impeller flow towards an annular opening which is coaxial with the front opening of the impeller chamber, and the impeller being adapted to rotate in either direction to cause liquid to flow in either direction. In the twostage pump shown, the pump stator comprises members A, B, C, member C affording a semitoroidal chamber which connects the impeller chamber to an annular passage coaxial with the impeller chamber and afforded by the members A, B. The pump casing is connected to a tank F by a pipe fitting G affording an inner pipe 64 connecting the impeller chamber to a diffuser 68, and an annular outer pipe 66 forming a continuation of the annular passage. Flow can be controlled by a valve H which provides a variable by-pass between the pipes 64 and 66. The electric driving motor is reversible to reverse the direction of rotation of the pump and hence the direction of flow. Where textile fibres are being dyed, washed or otherwise heated in the tank F, the reversal may take place automatically at pre-determined intervals. Instead of being curved as shown, the pipe fitting G may be of straight or other shape.
