Title: Cyclohexene compounds and process for making same
IPC: C07C47/46
Filed: 1959-05-05
Abstract: Hydroxyalkyl cyclic aldehydes of the general formula: <FORM:0868850/IV (b)/1> wherein R1 is a hydrogen atom and (a) C - - - C represent two carbon atoms joined by a single bond and R2, R3 and R4 are independently a hydrogen atom, a lower alkyl group, a phenyl group or a lower alkylated phenyl group, or (b) C - - - - C represent two carbon atoms joined by a double bond and R2 and either R3 or R4 are absent, are prepared by carrying out a Diels-Alder reaction between 2-methyl-2-hydroxy-6-methylene-octene-7 (myrcenol) and a dienophile having the general formula:  <FORM:0868850/IV (b)/2> wherein C - - - - C are joined by a double or a triple bond.  The reaction is carried out, at temperatures of up to 175 DEG C., in the presence of an anti-polymerization agent such as hydroquinone, t-butyl and di-t-butyl para cresols, and hydroquinone monomethyl ether.  In Example 1, a mixture of myrcenol and acrolein and a small proportion of hydroquinone is heated at 150 DEG C. for 41/2 hours in a sealed vessel.  The reaction-product is submitted to vacuum fractionation to separate 4-(4-methyl-4-hydroxy-amyl)-D 3-cyclohexene carboxalde hyde.  <FORM:0868850/IV (b)/3> Example 2 describes the reaction between myrcenol and crotonaldehyde to obtain the 6-methyl-compound.  Example 3 describes the reaction between myrcenol and propargyl aldehyde to obtain a mixture of isomers of 4-(4-methyl-4-hydroxy-amyl) D 3,6-cyclohexadiene carboxaldehyde.  In Example 4, the product of Example 1 is hydrogenated, in the presence of Raney nickel, to give 4-(4-methyl-4-hydroxy-amyl)-cyclohexyl carbinol which is then oxidized, by means of a solution of chromic oxide in anhydrous pyridine, to obtain 4-(4-methyl-4-hydroxy-amyl) cyclohexane carboxaldehyde.  The products of the examples are valuable perfume materials.  Myrcenol is prepared by the addition of the elements of water to the isolated double bond of myrcene Me2C:CH,CH2,C(:CH2),CH: CH2 (a) by reacting it with acetic acid, and subsequent saponification of the acetate, or (b) by reacting the myrcene with anhydrous hydrogen chloride, and subsequent hydrolysis of the hydrochloride.

IPC: E21C45/00
Filed: 1927-06-09
Abstract: 296,813. Stoces, B. June 9, 1927. Drawings to Specification. Hydraulic mining.-In mining gold &c. in placers by direct leaching with cyanide &c., pumping is first begun and the solvent then introduced at a. point where all the fluid is flowing towards the pump or pumps, so as to prevent loss of solvent. Where the placer contains fluid under a sufficient head, syphon pipes may replace the pumps. In dry placers, a pump or pumps supply water and a further pump or pumps withdraw it, the solvent then being introduced at an intermediate point. Where running water is present, a row of pumps is arranged at right angles to the direction of the flow, the solvent being supplied on the up-stream side of the pumps; alternatively, two rows of pumps may be provided, and the solvent admitted between the rows. The section of a placer under treatment may be surrounded by further pumps which prevent flow of exterior water to the section. If only a given layer of the placer contains metal, the solvent may be introduced only into this layer. Specification 17168/96, [Class 85, Mining &c.], is referred to.

Inventor: FEENEY THOMAS AQUINAS
IPC: B64C13/24
Filed: 1953-06-04
Abstract: 760,225. Controlling aircraft. NORTHROP AIRCRAFT, Inc. June 4, 1953, No. 15413/53. Class 4. [Also in Group XXXVIII] A full powered airplane control system comprises a pilot's control element movable in two planes at right angles to operate control surfaces either as elevators or ailerons and a variable length leverage arm, the length of which is a function of airspeed, connected between the control element and the surfaces so as to modify the movement of the surfaces for a given movement of the control element, only when the control element is moved to operate the surfaces as elevators. Dual controls are shown in Fig. 2, in which longitudinal movement of control levers 9 or 10 translates shafts 18 and 19 to rock saddle 22 about its pivot 14 through a variable length arm 17. This rocking, by links 24a, 24b and levers 25 rotates elevon cable quadrants 20a, 20b in the same sense to operate the elevons as elevators. Rotation of levers 9 or 10 in a lateral plane rocks shaft 11 in its bearings 12, which tilts the saddle 22 to rotate the cable quadrants in the opposite sense, to move the elevons as ailerons. Two way centering spring assemblies 30, 33 are provided, spring assembly 30 being connected to control lever 9 by a variable length rod 32. Referring to Fig. 3, the length of the rod 17 is variable by a screw and nut assembly 51, 52, rotatable by a D.C. motor 54 with reversed windings 55. A relay 83 has its winding connected to a pick off 72 of a potentiometer 75 controlled by a ram pressure air speed bellows rod 63b and to a pick off 79 of a potentiometer 78 controlled by the length of the rod 17. The relay contacts connect a battery 77 to one or other of the motor windings if the length of the rod does not correspond to the position of the bellows diaphragm. A precisely similar arrangement controlled by the same airspeed bellows is used to vary the length of the rod 32 connecting the control columns 9 and 10 to the elvator spring fed box 30. A manual cable 56 to the motor shaft is provided for an overriding pilot's control. The potentiometers may be non-uniformly wound to provide any given variation of movement ratio with airspeed. Specification 614,102 is referred to.

Title: Improvements in or relating to pulsator mechanisms for mechanical milking appliances
IPC: A01J5/12
Filed: 1947-06-12
Abstract: 623,974. Milking machine pulsators. SHIRLEY, R., and HOWSE, C. G. June 12, 1947, No. 15477. [Class 84] [Also in Group XXVI] A milking machine pulsator that is secured to a milking pail comprises a vacuum pressure engine that rotates a crankshaft to control the valve system of the engine and also to drive a cam to operate a valve or valves regulating the alternate application of vacuum and atmospheric pressure to the teat cups. The engine casing 17, 18 is formed with a number of diaphragm chambers 33 and the diaphragms 37 mounted in opposed chambers are mechanically coupled by rods such as 38, 39 so that when a vacuum is applied to one of each pair of opposed chambers 33 and atmospheric pressure to the other the rods move and cause rotation of the crankshaft 27. Since there are a number of pairs of interconnected diaphragms the rotation of the crankshaft is continuous. Mounted on the crankshaft is a pinion 47 which rotates a number of star wheels 51-53, the number corresponding to the number of chambers 33. The star wheels are mounted on a distributor block 57 and each controls the alternate application of vacuum and atmospheric pressure to a diaphragm chamber due to ports 58, 59 formed in each wheel, these ports connecting the pressure sources to passages such as 62, 65, 66 leading to a chamber 33. Vacuum pressure is supplied from the vacuum manifold 91, through a passage 100 past throttling valve 102 to an annular groove 101 and thence past each star wheel by a passage 63 to the passage 62 when the ports 59 in each wheel connect the two passages. Air at atmospheric pressure is supplied to the passage 62 by way of passages 67, 68 and passages passing through the diaphragm manifold plate 14 and distributer block 57 to the chamber 61 and thence through a passage 60 formed in each wheel to the port 58. The ports 58 and 59 in each wheel are arranged to reverse the pressure on each diaphragm every half revolution of the wheel. A locking ring 50 on the pinion 47 prevents the star wheels from being displaced with respect to one another. A pinion 74 keyed on the crankshaft turns through a pinion 82 a cam 79, the cam pro-: files 75a-78a of which rock arms 75-78 to cause oscillation of spring-loaded slide valves so that ducts 93 leading to the teat cups are subjected to alternate atmospheric and vacuum pressures. The air at atmospheric pressure is admitted gradually but the vacuum is applied rapidly or instantaneously. If all the teat cups are to operate together only a single face or rotary valve is used instead of the valves 88. Specification 600,666 is referred to.

Title: Improvements relating to inverter or converter circuit arrangements
Inventor: PELLY BRIAN RAYMOND
IPC: H02M7/515
Filed: 1963-04-19
Abstract: 1,002,728. Converting. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. April 3, 1964 [April 19, 1963], No. 15511/63. Heading H2F. A frequency changer for supplying an induction heater has one or more controllable rectifiers rendered conductive intermittently by a control circuit dependent on the output, and a starting circuit operated by breaking a current to the oscillatory load circuit to initiate oscillations therein. In the Figure the star connected econdary windings 11, 12, 13 of the input transformer are connected through diodes 15, 16, 17 and two groups of controllable rectifiers 18, 19, 20 and 21, 22, 23 to an inductor 25 whose centre tap is connected through another inductor 27 and protective resistor 28 to the star point. In operation the protective resistor is shunted by relay contacts 2R2. The controllable rectifiers of each group receive firing pulses simultaneously from the control device 30, of any suitable kind, which is responsive to the output waveform and supplies firing pulses to the two groups alternately. When phase 13, say, is most positive the controllable rectifiers 18 and 21 conduct alternately, commutation being due to the resonant load circuit 31, 32. Starting circuit and protection.-Two relays are provided, one, R2, being relatively quick and the other, R1, being relatively slow to de-energize. The coil of relay R1 is connected through a press-to-start switch 37, a pair of its own normally closed contacts 2R1 and a pair of normally closed contacts 1R2 of the other relay R2 to an auxiliary D.C. supply. Further contacts 1R1 of the relay R1 connect the resonant load circuit 31, 32 to an additional winding 33 on the input transformer when the relay is energized. When the start switch is pressed relay R1 is energized for a brief period so that current flows through contacts 1R1 into the load circuit and is then broken suddenly. The resulting oscillatory current starts the control device 30 which triggers the controllable rectifiers. If the circuit fails to start the process is repeated as long as switch 37 is closed. When operating the load voltage energizes relay R2, whose contacts 1R2 and 2R2 disconnect the starting circuit and short circuit the resistor 28 which limited current during the starting period. In the event of commutation failure, on starting or at other times, the quick acting relay R2 is released and resistor 28 put back in circuit.

Title: Improvements in aircraft steerable landing element mountings
IPC: B64C25/50
Filed: 1941-12-02
Abstract: 560,316. Aircraft landing gear. MACLAREN UNDERCARRIAGE CO., Ltd., and MAGLAREN, O. F. Dec. 2, 1941, No. 15536. [Class 4] In'an aircraft landing element structure comprising an auxiliary wheel arranged to contact the ground at landing, just prior to touching down of the main landing element thereby 'to pre-set the main element directionally in accordance with the direction of travel, the auxiliary wheel is carried by a structure which is pivoted to the support of the main element for up and down movement relatively to the main element support, against the resistance of a resilient device. The auxiliary wheel may also act as a servo-device to effect positive steering movement of the main landing element. As shown, an auxiliary wheel 9 is mounted by a steering pillar 10 on a frame 8 pivoted at 12 for vertical movement, to the swivelling fork 5 of a main landing wheel 7. A telescopic shockabsorber 16 extending between the fork 5 and frame 8 holds the wheel 9 in a relatively low position when the machine is in the air, so that this wheel, in landing, touches the ground prior to the wheel 7 and both wheels are turned about the axis of the fork 5 to correspond with any drift component in the direction of travel of the aircraft before the wheel 7 touches down. After landing the wheel 9 may be turned about the axis of the pillar 10 by a remote control cable 11 attached to an arm on the pillar and thus effect steering movement of the wheel 7 through the frame 8. The auxiliary wheel 9 with the frame 8 may be retractable and in the retracted position may engage a lug on a non- rotatable part of the mounting to lock the wheel 7 in its fore-and-aft angular setting. To avoid shimmy effect the wheel 9 may have a high pressure or a solid tyre or it may comprise two wheels rotatable about a common axis and set with a slight toe-in. Damping means may be provided operating between the fork 5 and a non-swivelling part. Specifications 509,923, 542,648, and 559,582 are referred to.
