Title: Improvements relating to coke ovens and the like
IPC: C10B27/02
Filed: 1931-01-09
Abstract: 356,079. Coke ovens.STILL, C., Recklinghausen, Westphalia, Germany. Jan. 9, 1931, No. 813. Convention date, Jan. 14, 1930. [Classes 51 (ii) and 55 (i).] Distillates are drawn off by suction from the charge in coke ovens by forming ducts in the coal, and bringing tubes secured in the oven roof into sufficiently gastight connection with the ducts. After the oven has been charged, iron rods 24 are pushed into the coal 10, forming ducts 23 into which tubes 21 are jammed, these tubes being inserted through sleeves 18, 19 formed with boxes 12, each tube having a bell 22 which dips into a water seal. The rods 24 may be left in the coal until it becomes sufficiently coherent to ensure the durability of the ducts. The rods may be pushed through the tubes 21 after these have been driven into the coal, or, a pressed coal cake, with holes already formed to register with the tubes 21, may be charged into the oven. After coking, the tubes are withdrawn upwardly. Distillates may be withdrawn from the gas space 20 through the usual outlets 6 leading by extension pipes 7 to the main 8, and also by suction through the tubes 21, boxes 12, conduit 15, and main 9, a pipe 17 drawing off the condensates, the oven may, however, be entirely filled with coal, the gas collecting space being omitted.

Title: Improvements in or relating to isotopic exchange processes
Inventor: WALKER PETER THOMAS
IPC: C01B4/00
Filed: 1966-01-07
Abstract: <PICT:1100991/C1/1> Ammonia or hydrogen is enriched in deuterium in a dual temperature ammonia hydrogen exchange process in which the ammonia stream from the hot tower (1) is split into two streams (11) and (12), the first of which is passed in countercurrent flow in a cold transfer tower to a hydrogen containing gas (preferably ammonia synthesis gas) and the second of which is passed through a cold tower in countercurrent to the hydrogen stream leaving the main cold tower; the two ammonia streams then being combined and passed to the main cold tower. In the preferred embodiment shown the hot tower 1 operates at about 20 DEG  C. and the cold tower 2, cold reflux tower 3 and cold transfer tower 4 operate at about - 70 DEG  C.  The system operates on liquid ammonia containing potassamide (35 g/litre) and pyrrolidine (16% by weight) and ammonia synthesis gas at a pressure of about 240 atmospheres. Ammonia circulates as shown by the solid lines and hydrogen as shown by the dotted lines.  Hydrogen leaves the hot tower 1 through line 23, is cooled in heat exchanger 21 where any condensed ammonia is removed via line 25, and then passes via line 26 to cold tower 4 and through line 27 to cold reflux tower 3.  This tower is small and may be attached to the top of the main cold tower 3.  The hydrogen then passes to heat exchanger 24 and thence to the hot tower, the hydrogen being saturated before entry with ammonia from the evaporator 6 in the ammonia line.  Ammonia from the hot tower (which is depleted in deuterium) first passes through evaporator 6 from which some of the gas is passed to the hydrogen line via 7. The remainder of the ammonia is cooled in heat exchanger 9 and split into two streams.  Stream 11 passes through cold reflux tower 10 and stream 12 is passed in countercurrent flow with an external stream of synthesis gas 13 and 14. The ammonia streams then pass through the cold tower 2 and through a finishing plant 19 from which the product, deuterium enriched ammonia is drawn off.  The remaining ammonia is heated in heat exchanger 9 and passed to the hot tower 1.

(2) A condensation product is obtained by mixing 5 parts of dimethylaniline with 4 parts of monochloracetic acid and water to a thin solution which is heated to 100‹ C. for two hours. The solution is then cooled to 70‹-80‹ 0. and 2 parts of 30 per cent. formaldehyde is added, and the mixture is heated in an autoclave at an excess pressure of one-tenth atmosphere. The product may be employed in conjunction with other ingredients.

Title: Starting device in carburetor
Inventor: SATOMI TOORU
IPC: F02M1/04
Filed: 1978-01-06
Abstract: PURPOSE: To make a preparation of starting dense mixture with ease, by means of opening the throttel valve simultaneously with an opening operation of the starter, with an inlet port of the starter air provided in an air suction passage at downstream of the venturi.  
     CONSTITUTION: When operated a cranking, a flow sum of fuel in passages 28A, 28B flows in a passage 28 by an air suction negative pressure of starting mixture passage 27, bing mixed with an air from an air passage 26, with a starting mixture constructed. And a quantity of air floming to pass a venturi is beng increased because of a throttel valve 5 being slightly open, and a quantity of air flowing in the venturi is almost proportional to an opening degree of the throttle valve, regardless of on and off of the starter, because an inlet port of the air passage 26 is located at the downstream of the venturi. In such way, the quantity of air flowing in the venturi is not decreased even for the starter being opened, further with a main air blocked by a valve 12, consequently, a high density mixture can be prepared.

Title: Door sash for automobile
Inventor: TAKAHASHI NAGAHIRO
IPC: B60J5/04
Filed: 1986-01-06
Abstract: PURPOSE:To prevent a waterdrop from entering the inside of a vehicle from the opening part of a glass by forming a projected edge part on the outer side face of an upper door sash which receives a side window glass, and restraining the rise of air flow accompanying traveling which flows along a glass surface. CONSTITUTION:A projected edge part 8b is formed on the outer side face 8a of an upper door sash 8 for receiving a side window glass 2. Thereby, when a vehicle is traveling, an air flow which flows on the side of a door 1, flows along a glass surface 2 forming a track F and is restrained from rising up at the lower part of the projected edge part 8b, flowing to the rear of the vehicle passing through the side of a pillar 10, without passing over a gap 4 between the upper door sash 8 and the side window glass 2. Accordingly, even when a waterdrop 7 is deposited on the side glass 2, the waterdrop 7 is made flow to the rear of the vehicle along with the air flow accompanying traveling, thereby, preventing a waterdrop 7 from entering the inside of the vehicle through the gap 4.
