Patent GB-209379-A (GB)
Title: Improvements in or relating to the treatment of ammonia charged gas
IPC: C10K1/10
Filed: 1923-02-06
Abstract: 209,379. Koppers Co., (Assignees of Bird, E. H.). Jan. 2, 1923, [Convention date]. Ammonia; ammonium sulphate; carbon dioxide; sulphuretted hydrogen.-The process for scrubbing gases with a non-volatile alkali solution and regenerating the latter by heating at suitable pressures as described in Specification 190,115 is applied to gases containing ammonia, and impurities such as sulphuretted hydrogen, carbon dioxide &c., the ammonia being recovered as ammonium sulphate. Aliquor containing an alkaline earth may also be employed for scrubbing the gases but preferably a sodium carbonate solution is used. In Fig. 1 plant is indicated in which the invention is embodied in the " indirect process " of ammonia recovery. Gas such as coke oven gas from the ovens 1 passes through a collecting main 3, cooler 5, and tar extractor 7 to a scrubber 9 containing an alkaline liquor of such volume and strength that all the ammonia is absorbed. Preferably a solution of sodium carbonate containing a small amount of bicarbonate is employed. The purified gas leaves by a pipe 13 and the saturated liquor is distilled in a column 17 by means of direct steam. All the ammonia and about half the sulphuretted hydrogen is thus removed. By regulating the pressure a further quantity of the sulphuretted hydrogen and some carbon dioxide are evolved. The liquor is completely regenerated in an evaporator 22 by heating and regulating the pressure. The gases evolved in the column 17 and the evaporator 22 together with the ammonia obtained by decomposing in a still 36 the ammoniacal liquor which condenses in the collecting main, cooler &c., are finally passed into a saturator 28 producing ammonium sulphate. By conveying the unabsorbed gases into the pipe 32 the sulphuretted hydrogen may be utilized in heating the ovens. In a modification, the concentration of the alkaline liquor used in the scrubber 9 is such that little ammonia but most of the sulphuretted hydrogen is absorbed. The fouled alkaline liquor running from the scrubber is treated as in the " indirect " process described above and the unabsorbed gas is passed into a second' saturator after going through a re-heater. A further arrangement of plant is described in which the portion of the fuel gas used for heating the ovens is not scrubbed with alkaline liquor but passes to a saturator after being cooled and having its tar extracted. The remaining or surplus gas is treated as in the modification described above in which the ammonia is recovered partly by the " direct " and partly by the " indirect " method, the gases obtained by distilling the fouled absorption liquor and the ammoniacal solutions from the tar extractor &c. being conveyed together to the saturator receiving the unscrubbed gases.
Patent GB-451360-A (GB)
Title: Improvements in or relating to clutches for spur-wheel variable speed gears
IPC: F16D11/10
Filed: 1935-02-04
Abstract: 451,360. Claw - clutches ; variablespeed gearing. MOLDENHAUER, E., 58, Charlottenstrasse, Dusseldorf, Germany. Feb. 4, 1935, No. 3621. [Class 80 (ii)] The end faces of the co-operating claws 5, 7, Fig. 1, of a claw-clutch, used in the variable-speed gear of a motor-vehicle, are uniformly inclined so that engagement cannot occur if the driven part is overrunning, the movable clutch member 3 being connected with its associated shaft 11 by projections 22 on the former engaging grooves 2 in the latter, which grooves and projections have inclined parts 23 and 24 such that the driving torque tends to engage the clutch. An auxiliary sleeve 12, splined on the member 3 (or on the fixed clutch member 9), and operated by the brake mechanism of the vehicle, has claws 13 engageable with claws 21 on the member 9 (or on the member 3), the end faces of these claws 13, 21 being inclined oppositely to the claws 5, 7, so that, when the driven part is overrunning, the claws 13, 21 engage upon actuation of the brake and the claws 5, 7 can then engage. The movable member 3 is common to two claw clutches, the second clutch being similar or being of ordinary construction ; in the former case, two auxiliary brake-actuated sleeves are provided and the projections 22 and grooves 2 have doubly-inclined parts as shown at 90, 91 in Fig. 9, wherein two double-ended claw sleeves 77, 78 are arranged on the driven shaft 82. A gear 69 is fast on the driving shaft 81, gears 71, 73, 75 are loose on the shaft 82, and constantly-meshed countershaft gears 70, 72, 74, 76 normally rotate together. A claw clutch 36 is, however, provided whereby the gear 76 can be disconnected from the other countershaft gears, whereupon a reversing train (not shown), can be brought into action. The three brake-actuated auxiliary claw sleeves 87, 88, 89 are controlled by a longitudinally-movable rod 38, Fig. 10, linked to the brake pedal 61 through the intermediary of a spring 63, while the pedal 67 controlling the engine clutch 60 has a hooked member 66 which operates to prevent actuation of the rod 38 except when the pedal 67 is depressed to disengage the engine clutch. Specifications 383,827 (as open to inspection under Sect. 91) and 397,321 are referred to.

Abstract: 898,262. Diaphragm pumps. FULLWOOD & BLAND Ltd., R. J. April 29, 1960 [Feb. 3, 1959], No. 3806/59. Class 102(1). A pump for use as a releaser device in a vacuum milking apparatus comprises a pump diaphragm 1 and driving diaphragms 2, 3 all mounted on a rod 4. The pump diaphragm 1 and the member 14 form a chamber having a port leading to nipple 17; the diaphragm 2 and member 14 form a chamber having a port leading to nipple 22, and the diaphragm 3 and member 25 form a chamber having a port leading to nipple 29. The chamber between the diaphragms 2, 3 is in communication with the atmosphere. The member 13, forming part of the pump chamber has outlets 30, 40 leading to valve chambers 31, 41 fitted with gravity operated poppet valves 33, 43. In operation, the opening 42 of the valve 41 is connected to a receiving vessel under reduced pressure, directly linked to the milk pipe line of the vacuum milking apparatus, and the opening 32 of valve 31 is connected to a milk container at atmospheric pressure. The nipples 17, 29 are connected to the pulsator and nipple 22 to the vacuum pump. The driving diaphragm 2 is caused to flex towards the right and so the volume of the pump chamber decreases. When the pulsator communicates with the vacuum pump, the larger area of the diaphragm 3 causes the pump diaphragm to move to the left and so the pump chamber alternately expands and contracts as the pulsator alternately connects with the atmosphere and vacuum pump. As the volume increases, valve 33 closes and 43 opens and allows milk to pass into the chamber. When the volume decreases, valve 43 closes and 33 opens and milk flows into the receiving container. In modifications of the invention, there may be three or more driving diaphragms, each of the same area. Specifications 602,938 and 795,702 are referred to.

The Figure shows capacitors 10a-10f connected in parallel via resistors 11a-11f and 12a-12e to charge across the D.C. supply 16. When a triggering pulse is applied to terminal 18 the ignitrons 14a-14f are rendered conducting to discharge the capacitors 10a-10f in series, the output pulse at terminal 26 being applied to the load 20. The ignitrons may be of the sealedoff mercury vapour type. In a modification, Fig. 2 (not shown), the triggering electrodes of the ignitrons are all resistively coupled to the firing terminal. In a further modification, Fig. 3 (not shown), the triggering electrodes of the ignitrons nearer to the earth potential end of the generator are resistively coupled to the firing terminal the remainder having their triggering electrodes capacitively coupled each to its own anode terminal. These latter tubes are rendered conducting by the triggering electrode, being driven positive with respect to cathode due to the rapid increase of voltage across each of these latter tubes when the earlier ones are fired.
