Title: Improvements in or relating to the production of benzene carboxylic acids
IPC: C07C17/32
Filed: 1955-04-05
Abstract: Benzene polycarboxylic acids are obtained from benzene homologues by (1) chlormethylation, with chlormethylether or with formaldehyde and hydrogen chloride, to give a mono- or di-chlormethyl body and obtain a derivative of benzene containing at least three alkyl and chlormethyl groups; (2) oxidation of the product with nitric acid at atmospheric pressures to oxidize the chlormethyl groups and give a chlorine-free intermediate; (3) oxidation of this intermediate with nitric acid at elevated pressure to oxidize the residual alkyl groups.  Nitric acid of 38-47 per cent strength may be employed in stage 2 and 30-38 per cent strength in stage 3, and the same acid, weakened by the reaction, may be used without separation in both stages.  An oxygen-containing gas may be passed through during reaction.  The mono- and di-chlormethylated bodies are prepared together if a substantial excess of formaldehyde is used, and then, (1) they may be oxidized together, the acids obtained being separated by fractional crystallization; or (2) the crystals of dichlormethyl body which separate on cooling may be oxidized separately; (3) the mono-chlormethyl body may be separated by distillation and separately oxidized or further chlormethylated to give dichlormethyl body. Terephthalic acid is obtained as a by-product when crude xylene containing ethylbenzene is used as starting material.  In examples: (1) m-xylene is chlormethylated, and the oily crystal layer separated and filtered, the crystals of dichlormethyl body being oxidized as above to pyromellitic acid, and the oily liquid mixture is either oxidized to pyromellitic and trimellitic acids, separated by fractional crystallization, or fractionally distilled and the separated mono-and di-chlormethyl bodies are oxidized; (2) crude xylene is treated as under (1), terephthalic acid being obtained as a by-product; (3) 2,4-dichlormethyl toluene is oxidized with nitric acid to give a chlorine-free methyl-phthalic acid, which is further oxidized to trimellitic acid; (4) pseudo-cumene is chlormethylated, and the crystals of dichlormethyl body oxidized with nitric acid to benzene pentacarboxylic acid; (5) durene or isodurene is similarly converted to mellitic acid; (6) crude xylene is monochlormethylated and the monochlormethyl compound is oxidized with nitric acid in two stages.

Title: Scavenge pump device in uniflow engine
Inventor: SHIMODA KUNIHIKO
IPC: F02B33/44
Filed: 1985-01-10
Abstract: PURPOSE:To obtain a high scavenge pressure even if an auxiliary motor blower is eliminated, by utilizing a scavenge valve which slides on the inner surface of an engine cylinder and opens and closes scavenge holes, and a scavenge pump chamber in which a partition wall is provided in a scavenge sump so that a closed space is defined below the piston. CONSTITUTION:When the load of an engine is below 50%, a valve 54 is opened while a discharge valve 56 is closed to introduce high pressure air into an air cylinder 52 so that an air piston 53 serves as an air spring 53. As a piston 17 ascends, scavenge air is introduced from a scavenge air inlet chamber 41 into a scavenge air pump chamber 42 through a check valve 44. A scavenge port 12 is closed by a scavenge port valve 51. When a piston 17 descends, pressure in a scavenge chamber 42 increases so that scavenge air flows from the scavenge air pump chamber 42 into a scavenge air pump 19 through a check valve 45. Further, the piston 17 lowers to depress the scavenge port valve 51 overcoming the air piston 53 so that scavenge air flows into the cylinder through scavenge holes 12. When the load of the engine is above 60%, high pressure air in the air cylinder 52 is discharged so that the same scavenge operation is carried out as that in conventional engines.

Title: Transfer rod
Inventor: ISHIGURO SHIYUUICHI
IPC: B23Q11/00
Filed: 1984-01-11
Abstract: PURPOSE:To mininize the position deviation without rectification by fixing the 1st rod member, in which a workpiece is positioned, to one end of the 2nd rod member which is same in heat expansion ratio as the 1st rod member, and the other end of which is connected to the driving source, and which is vertically slidalby stacked. CONSTITUTION:When rods are heated up, the 1st rod member 11a stretches to the left due to fixed state of a hydraulic cylinder 3 in its position and direction of elongation delta of the 2nd rod member 11b is directed to the right due to its left end fixed to the rod 11a. Accordingly, the elongation delta composed of those of the rod members 11a and 11b is shown by a straight line PR. Since the straight line PR exists within a parallellogram OPQR, the elongation delta composed of those of the rods 11a and 11b is smaller than the single elongation delta of each of the rods 11a and 11b, and also the relative elongation delta becomes zero at an intersection point m of the straight lines PR and QO. Accordingly, if delta is selected according to the accuracy of transfer machines, and the positions P1 and Pn are set between P (m+alpha) and P (m-alpha), the affection of the elongation delta can be minimined.

Title: Fast forward/rewinding/stop-detecting circuit for video tape recorder
Inventor: WATABE FUMIO
IPC: H04N17/06
Filed: 1988-01-08
Abstract: PURPOSE:To accurately detect the fast forward/rewinding/stop operation of a video tape recorder by providing a synchronizing separator circuit that takes out a horizontal synchronizing signal and a vertical synchronizing signal from a reproduced video signal, a video signal discriminator circuit, a counter, etc. CONSTITUTION:The synchronizing separator circuit 20 takes out a horizontal synchronizing signal S37 and a vertical synchronizing signal S38 from a video signal reproduced by a video tape recorder VTR, and the signal S37 is supplied to the video signal discriminator circuit 26. The circuit 26, upon judging the signal to be normal, supplies an output S45 to the clock input terminal of a preset counter 27, and at the same time, supplies the signal S38 to the reset terminal of the counter 27. In case the operation is normal reproduction, the circuit 26 lets the signal S27 pass through itself as it is, but in case either one of fast forward, rewinding and stop operations, the signal S37 comes disordered, hence the signal is inhibited to pass through and thus the execution of either one of said operations can be detected. At the time of detecting disorder in the signal S37 by the counter 27, an operation discriminating circuit 28 can detect which one of said three operations the operation actually is.
