Patent GB-943193-A (GB)
Title: Process for the separation of pyridine derivatives
Inventor: WADDINGTON WRIGHT
IPC: C07D213/06
Filed: 1959-01-05
Abstract: A mixture of pyridine homologues is resolved into a first component substituted in the 2-position and a second component having the 2-position free by treating the mixture with a mineral acid salt of nickel, cobalt or iron to form a complex with the second component, separating the complex from the first component and decomposing it to regenerate the salt and the pyridine homologue(s) of the second component.  The pyridine "homologues" referred to comprise mono-, di- and tri-alkyl pyridines, quinoline and isoquinoline.  The complex may be separated from the first component by partitioning the mixture between water and a hydrophobic solvent for pyridine homologues.  The decomposition of the complex may be effected by heating an aqueous solution of the complex, e.g. at 80-100 DEG C. and the heated residue may then be extracted by extracting with a hydrophobic solvent, e.g. toluene, or by distillation.  Alternatively the complexes may be decomposed by treatment with caustic soda.  In the examples (a) a mixture of pyridic homologues is separated into two components-one containing 2,6-butidine, a -picoline and 2-ethyl pyridine and the other containing b -picoline and g -picoline; and (b) a mixture of quinoline and isoquinoline is separated into its two components.

Abstract: 988,562. Treatment of plants. ETHYLENE-PLASTIQUE S.A. Jan 3, 1964 [Jan. 17, 1963], No. 333/64. Heading A1E. [Also in Division B4]  Tongs for use in holding fruit buds comprise a pair of arms 1, 2 pivoted at 3, a cam slidably mounted by means of a slot 9 on the pivot 3, the cam bearing on a track 17 provided on the arm 2. The cam in one of its end portions in the slot allows pivotal movement of the arms and in the other end position serves to lock the arms in closed position. In the position shown, the jaws can be opened by exerting a slight pressure on the free ends of the arms. The arms are closed by applying manual pressure to the push member. 14 to move the cam in a direction away from the chambers 15, 16 and cause pivotal movement of the arms. A lug 18 at the end of the arm 1 prevents the cam from lifting when the arms are in closed position. The tongs are made of polyethylene or other plastics material, the track 17 being rendered resilient in that only one end thereof is connected to the arm 2. The chambers 15, 16 are provided with pads of expanded material. Specification 941,562 is referred to.

Abstract: 589,446. Rotary engines. FARESO, J. A. Jan. 6, 1945, No. 591. [Class 110 (ii)] In a rotary engine of the type in which a pair of arcuate annular cylinders mounted on a rotary output member co-operate with a pair of pistons mounted on an oscillatory member which rotates with the output member and oscillates relatively thereto, the relative motion between the members is obtained by means of a connecting rod which is journalled centrally on a stationary crank-pin offset with respect to the axis of rotation of the output member and has two oppositely extending arms, each of which is slidably and rotatably connected to one of said members. The two arcuate cylinders 19 form part of a rotor 18 to which is secured or formed integrally therewith an output shaft 15 and a hollow shaft 24. The shafts are journalled in bearings 17 carried by a casing 11. The pistons 20 are carried by a member 21 which is journalled on a stationary shaft 22. A double-ended connecting rod 26 is journalled on an offset portion 25 of the shaft 22 and is slidably connected to trunnions 29, 30 which are pivotally connected to the member 21 and the rotor respectively. The shaft 22 can be pivotally adjusted about its own axis to control the position of the pistons and thus to advance or retard the ignition timing. A circular recess may be formed on the rotor to provide, in conjunction with a similar recess formed in the casing 11, an annular channel communicating with bores or passages in the rotor and the casing for the transfer of fuel to the cylinders. Cylinder heads 31 are provided with ignition means and inlet and exhaust valve gear. The rotor is provided with cooling ribs 32. A multicylinder engine may be constructed from a number of units of the type described. According to the Provisional Specification, the cylinders may be straight instead of curved, the pistons being connected to the rotor by link arms ; alternative means for obtaining the relative motion between the pistons and cylinders, involving the use of cams, are described.

Title: Optical transceiver
Inventor: YOSHIDA TAKASHI
IPC: H04B10/27
Filed: 1994-01-06
Abstract: PURPOSE:To inexpensively realize a self-diagnostic function by detecting a light receiving output voltage when only a leaked light from a light emitting means directly to a light receiving means is received so as to omit excess optical fiber signal lines for diagnosis. CONSTITUTION:When a control section is received by an optical transceiver 1, a drive circuit 21 stimulates a light emitting element 22 based on a control signal from a light emitting control circuit 20. The light is sent to a peripheral equipment via an optical branching coupler 105 and an optical fiber signal line 4, and simultaneously a leaked light is received by a light receiving element 32 via optical paths 51, 52. When a light emitting means 2 is deteriorated and the intensity of the stimulated light is reduced, the intensity of the leaked light is educed. In this case, when the light passing through the line 4 is not in existence, an output voltage VO of the light receiving means 3 gets lower than a 2nd reference voltage TH2 of a comparator 8. As a result, an abnormal signal is outputted from the comparator 8 and the signal and a light emitting signal S20 from the circuit 20 are multiplexed and a logic discrimination circuit 7 provides an output of a signal representing a fault.
