Title: Improvements in and relating to direct contact jet condensers
Inventor: HAYDEN ROBERT LESLIE JAMES
IPC: F28B3/00
Filed: 1950-04-21
Abstract: <PICT:0700747/III/1> <PICT:0700747/III/2> In a direct contact jet condenser for use as an intercondenser or as an after condenser in an air-evacuation system of the steam-jet type, wherein an upflowing mixture of steam and air from an ejector it contacted with downflowing streams of cooling water supplied from a spray-head, a jumbled mass of loosely-packed ferrules is supported in the condenser-casing between the spray-head and the inlet for the mixture of steam and air, whereby efficient steam condensation and air cooling are obtained at a low pressure drop.  In the condenser shown (Fig. 1), the mixture of steam and air is introduced into the casing 10 through inlet 24; and cooling water is introduced through spray-head 16, which has six nozzles 18.  The mixture of steam and air contacts the cooling water in a jumbled mass of brass ferrules 14, supported on grating 12.  The ferrules are formed of sheet metal as shown in Fig. 2, the longitudinal rib 28 obviating the engagement of one ferrule within another.  In a casing having a diameter of 18 ins., ferrules having a diameter and a length of about 1 5/8 ins. in a mass 10 ins. deep, give good results.  Cool air is discharged from the condenser through outlet 26; water is discharged through outlet 22.  Stoneware or porcelain ferrules can also be used.

Title: Selective Catalysis
IPC: C07C7/148
Filed: 1967-03-02
Abstract: 1,164,535. Zeolitic catalysts. MOBIL OIL CORP. 2 March, 1967 [2 March, 1966], No. 9899/6T. Heading B1E.[Also in Divisions C2 and C5] A crystalline aluminosilicate zeolite catalyst is used in a method of preferentially reacting one of a plurality of organic compounds which and at least one other of which, is of dimensions which enable it to enter the pores of the aluminosilicate, in which method the one compound differs from .the other with respect to the catalyst by possessing a substantially higher rate of sorption, the product of the preferential reaction being itself of dimensions which enable it to pass from the crystalline aluminosilicate. Catalytically active material may be introduced into the crystal lattice e.g. zinc, cobalt, nickel and silver,by contacting the zeolite with solutions containing them. Further, catalytic centres may be obtained by exchanging part of the metal ion of the aluminosilicate with an ion exhibiting suitable catalytic activity e.g. silver, copper, gold, aluminium, hydrogen, zinc, strontium, cobalt, potassium, nickel, rare earths, ammonium, cadmium, mercury, lithium and magnesium. Reactions described include preferential cracking, hydrogenation and halogenation.

Title: Reactor furniture for purifying waters
Inventor: NAGY OLIVER
IPC: C02F1/00
Filed: 1987-07-21
Abstract: The proposed equipment contains a reactor chamber operating with hydrostatic overpressure as a quasi-mixed-vessel. The overpressure is used to produce circulation in the settling space. The mass flow of the circulation producing reaction mixt is independent of the reactor loading, as it is equal to the sum of the recirculation and fresh feed flows. If necessary, the equipment will also produce circulation in the reaction space. These features ensure, in spite of the simplicity of the equipment, high specific volumetric and surface loading and high clean-up efficiency. the reactor can be used for a variety of applications, such as raw water and waste water clarification, softening and waste water biological treatment.

Abstract: PURPOSE:To make it possible to easily correct errors of the positions in the transverse direction of grooves of many disk trays and further to prevent the inclined arrangement of respective wall members by improving the compression spring parts provided between the wall member at the extreme right end and side plate. CONSTITUTION:Three pieces of columnar supporting rods 4a, 4b, 4c are spanned in parallel with each other between two pieces of the side plates 1a and 1b via the shaft holes of the side plates. Many pieces of the wall members 5 each having a small sheet thickness are inserted into these supporting rods. The wall members 5 are successively superposed on each other, by which the grooves 8 for housing disks are formed between the adjacent wall members. The compression springs 7 are provided between the wall member 5b at the extreme right end and the side plate lb. The supporting rod 4a is provided with a collar 16 and thin washers 17 in place of the compression springs. As a result, the perpendicularity of the wall members and the deviation in the transverse direction between the grooves 8 for housing the disks and the detecting parts are adjusted by properly selecting the number of sheets of the thin washers 17. Free setting of the compression rate is thus possible. The surfaces of the wall members are protected by using a resin contg. a rubber component for the wall members 5.

Abstract: PURPOSE:To enhance husking performance by holding one rubber roll to a shaft in the oblique upper part and holding the other rubber roll to a shaft in the oblique lower part and fitting the lower rubber roll to a laterally moved rotary shaft so as to be rotated and freely laterally moved and providing a flow plate for supplying unhulled rice between both rolls. CONSTITUTION:One rubber roll 7 is held to a shaft in the oblique upper part and the other rubber roll 8 is held to a shaft in the oblique lower part respectively. Further the roll 7 is fitted to a fixed rotary shaft so that only rotation is freely performed and the rubber roll 8 is fitted to a laterally moved rotary shaft so as to be rotated and freely laterally moved. The roll 7 is rotated at the circumferential speed speedier than the roll 8. Furthermore a flow plate 4 for supplying unhulled rice is provided between the rolls 7, 8 and a groove 13 is formed along the flow direction on the flow face of the flow plate 4. As a result, the phenomena such as bit failure and rebound of unhulled rice 12 are not almost caused. Further the fine locational relation of the roll 7 for flow of unhulled rice can be accurately held and rational rice husking is enabled.

Title: Pulse width modulator
Inventor: SOBASHIMA AKIRA
IPC: H04N5/14
Filed: 1985-01-09
Abstract: PURPOSE:To improve the S/N by loading an n-bit data to two counters operated at a clock frequency fC at a prescribed sampling period. CONSTITUTION:A high-order (n-1)-bit of an n-bit data from an input terminal 1 is loaded to a counter 5 by using a pulse outputted from a pulse generator 3 at each sampling period TS=1/fS and the n-bit is loaded to a counter 4. After data load, the 1st counter 5 starts counting in a clock frequency fC and when the count reaches a prescribed value, the count of the 2nd counter 4 is started. When the count reaches a prescribed value, the count is stopped. Then an output of both the counters is given to a combination circuit 6, from which a signal subject to pulse width modulation is obtained. Thus, the data word length (n) to be handled is expressed as log2(fC/fS)-bit, and since the pulse width control is attained by the accuracy of the operating frequency fC, the S/N is improved.
