Title: Liquid formulations of herbicidal mixtures
Inventor: FRISCH GERHARD
IPC: A01N47/30
Filed: 1990-06-08
Abstract: Abstract of the disclosure Liquid formulations of herbicidal mixtures Stability problems  and,  in particular,  instabilities caused by crystal growth, and changes in the biological availability of the active substances frequently occur in formulations  of mixtures  of water-soluble,  salt-like active  substances  with  active  substances  which  are insoluble in water, depending on the composition. The invention relates to particularly stable formulations of mixtures on the basis of linuron and active substances which are dissolved in salt-like form from the group comprising the phenoxyacetic and phenoxypropionic acids, glufosinate, glyphosate, dimethylphosphinoylhydroxyacetic acid and 1,1'-dimethyl-4,4'-bipyridinium chloride. The formulation  auxiliaries  are,   essentially,   lignin-sulfonates and salts of polymerized alkylnaphthalene-sulfonic acids.

IPC: C08G65/40
Filed: 1990-08-08
Abstract: Abstract of the disclosure Process for the preparation of an aromatic polyether.            A process for the preparation of an aromatic polyether by condensation of dihydric phenols with activated aromatic dihalo compounds or by self-condensation of polynuclear activated halophenols employs a mixture of sodium carbon-ate and sodium hydrogen carbonate as  a condensation auxiliary.            By this means,  the relatively low reactivity of the sodium carbonate is enhanced and the reaction rate is significantly increased.

Inventor: KLEY DIETER
IPC: G01N31/00
Filed: 1990-09-18
Abstract: ABSTRACT OF THE DISCLOSURE.       Air containing water-soluble oxidizing agents, usually predominantly hydrogen peroxide, is exposed in concurrent flow to water that may be acidified if the air contains interfering acidic reducing agents such as sulfur dioxide.  After that exposure the gas is separated from the liquid and, if the stripping liquid has been acidified, it is then neutralized.  The neutral stripping liquid containing the oxidizing agents is mixed and then reacted with an iodide solution in the presence of a catalyst, after which the reaction products are passed, as the cathode solution, through an electrochemical concentration cell which has an anode chamber filled with a concentrated iodide solution as an anode solution. The volume of air exposed to the stripping liquid is continuously measured and likewise, in the concentration cell, the iodine formed before the mixed solution enters the concentration cell is continuously measured, so that content of water-soluble oxidizing agents in the air can be continuously measured or monitored.
Patent CA-2026465-A1 (CA)
Inventor: FAHY ARTHUR J
IPC: F16H48/285
Filed: 1990-09-28
Abstract: ABSTRACT            (Reference is made to Figure 5) A differential mechanism is provided with two output shafts 202 and 204 coaxially arranged and extending to wheels 203 and 205 of a vehicle.   The differential is provided with a pair of connected discs 221, 209, the disc 209 being rotated about the common axis of the shafts 204,  202 by a drive shaft  206  and  a  pinion.   An  intermediate  shaft  211  is eccentrically positioned between the two discs 2099 221 and is formed with a circumferentially extending spiral tooth 241.  The tooth 241 engages a driving gear 217 fixed to the shaft 202 at one end-portion and the other end-portion of the member 240 provides a member in mesh with the second member  216 fixed  to  the  shaft  204.     The  teeth of the members 216 and 240 are shaped and positioned so that drive between them is inefficient but they will translate over one another if the member 216 is rotated in the same direction and at the same speed as the member 240.   This occurs when the vehicle is cornering and one wheel  is increasing in speed  while  the  other  is reducing  its  speed.    In  the situation  where  one  wheel  loses  ground  adhesion,  the differential  prevents  said  one  wheel  from  racing  and removing drive torque from the other wheel.

Title: Shock absorbing motor mount for a rotary cutter
Inventor: DETTBARN DEKE
IPC: F16F15/06
Filed: 1990-12-24
Abstract: A shock absorbing motor mount for heavy duty rotary cutting machines commonly equipped with a frame and a hydraulic motor or the like mounted on the frame for driving a rotating cutting blade is disclosed. The shock absorbing motor mount includes a bearing for rotatably mounting the motor to the frame and a means such as a torsion arm for limiting the rotation of the motor with respect to the frame to permit an effective transfer of power from the motor to the cutting blade and normally maintaining the motor at a neutral position. The means for limiting the rotation generally includes a resilient shock absorbing means such as compression springs mounted on one end of the torsion arm for progressively decelerating the rotation of the motor when the cutting blade strikes an object which possesses sufficient inertia to induce a rotation of the motor with respect to the frame, and for returning the motor to the neutral position.

Title: Ribbon-type dispensing cap construction
Inventor: STULL GENE
IPC: B65D47/24
Filed: 1991-02-01
Abstract: RIBBON-TYPE DISPENSING CAP CONSTRUCTION                Abstract A dispensing cap construction for containers, hav-ing a cap body for attachment to a container neck, and having a discharge spout portion through which the con-tainer contents can be discharged, and a closure cap turnably carried by the cap body. The closure cap has a non-round or slit-shaped orifice, and a stopper blade in the closure cap is received in the orifice so as to close it off. The stopper blade is turnably mounted on the spout portion of the cap body to enable it to turn simul-taneously with the closure cap. Cooperable elements on the cap body and closure cap effect relative axial move-ment of the stopper blade and the closure cap in response to turning of the closure cap on the cap body, thereby to enable the stopper blade to close and open the orifice as the cap shifts. The orifice imparts a wide and thin, ribbon-shaped characteristic to the discharged product, and is especially well adapted for dispensing mustard, ketchup, cream dressings or the like where such a ribbon characteristic is desired. The advantage of the present construction over the devices of the prior art is that the components of the construction are not stressed or bent during normal use, thereby eliminating problems with breakage, and with the components possibly taking a "set", which might interfere with proper operation.

Title: Aircraft aircrew life support apparatus
Inventor: FOOTE JAMES C
IPC: A62B9/02
Filed: 1991-03-12
Abstract: A breathing demand regulator for use in aircrew life support apparatus has an aneroid capsule 56 coacting with a valve head 50 to restrict outflow from a breathing pressure control chamber 32. The aneroid capsule expands t.o move the valve head in the event of aircraft cabin altitude rising above a predetermined level due to loss of cabin pressure. An end face 53 of a valve stem 51 supporting the valve head senses inflation pressure of an aircrew G-suit by way of a passageway 59 for movement of the valve head in the presence of G-load. This arrangement provides for increased control pressure and, hence, increased breathing gas pressure in a regulator outlet 13, in meeting the higher of requirements for positive pressure breathing to protect an aircrew member exposed to both G-load and high aircraft ambient altitude (say above 12000 metres).      The regulator is disclosed in combination with an anti-G valve arrangement 90, 100 and a G-suit inflation control valve arrangement 60, 61 and 120, 121 that provides the higher of G-suit inflation pressure requirement for protecting the aircrew member when exposed to high aircraft ambient altitude in the presence of G-load.
