Patent GB-803591-A (GB)
Title: Improved metabolic processes
IPC: C12P27/00
Filed: 1955-12-30
Abstract: Gibberellic acid is obtained in a process which comprises the cultivation of an active strain of Gibberella fugikuroi in an aerated nutrient solution characterized in that carbon dioxide is also introduced into the solution.  Preferably the carbon dioxide is introduced in a proportion not greater than 10 per cent by volume of the air used for aeration.  Examples illustrate the increased yield of gibberellic acid obtained by the use of carbon dioxide. Specification 783,611 is referred to.

Title: Improvements in or relating to centrifugal machines
IPC: F04D7/06
Filed: 1928-12-20
Abstract: 316,503. Sulzer FrÞres Soc. Anon. Sept. 6, 1928, [Convention date]. Balancing moving parts; compensating for unequal expansions. - Elastic members 13, 14 are arranged to rotate with the shaft 5 of a centrifugal pump for high-pressure hot water, or other rotary machine in which the shaft and the parts connected to it have different coefficients of expansion. The space between the members 13, 14 may be filled with water under pressure and the members act as springs to press the impellers, or other members on the shaft, against the collar 15. To balance the axial thrust, water under pressure from one of the pump stages is passed through the slot 8 into the chamber 9 from which it passes in a thin film according to the position of the relief disc 10.

Patent GB-1420729-A (GB)
Title: Pneumatic control device
IPC: F16P3/22
Filed: 1974-08-29
Abstract: 1420729 Pneumatic control circuits ROBERT BOSCH GmbH 29 Aug 1974 [1 Sept 1973] 37783/74 Heading F1P The pneumatic control device shown, Fig. 1, comprises three valves 8,9,10 and two pushbutton valves 3, 4 for supplying signals to the valves 8-10, the arrangement being such that in order for compressed air to be supplied from a port A9 both push-buttons must be operated within a given period of time determined by a time delay device 11. The latter comprises a throttle 12 and a chamber 13. As described, the device is used as a safety device for a press and an operator has to use both hands to operate buttons 3, 4 substantially simultaneously. When button 3 is pressed, compressed air from a pump 6 passes through a line 7 to a port Z8 and moves valve 8 to its second position in which compressed air is fed to the delay device 11, through ports S8, A8. If the button 4 is not pressed before the air passes through the delay device 11, compressed air flows through ports R9, B9 of valve 9 and to port Z10 of valve 10 which changes this valve to its second position. This closes port R10 so that any subsequent flow of air caused by pressing button 4 is blocked. If button 4 is pressed within the delay period, compressed air is supplied through ports P8, B8, R10, B10 to port Z9 so that valve 9 is moved to its second position. Thus, air coming from port 59 passes through port A9 to the ram 1.

Title: Improvements in shaft seal assemblies for rotary pumps
IPC: F16J15/00
Filed: 1959-11-10
Abstract: 860,456. Stuffing-box substitutes, TORNBERG & LUNDBERG A.B. Nov. 10, 1959 [Nov. 13, 1958], No. 38063/59. Class 122 (5). The shaft 13 of a rotary pump is sealed by means comprising a non-rotatable sealing ring 55 engaged by a rotatable sealing ring 57 and one or more elastic sealing lips 49, 51 engaging a conical surface of a body 53 attached to the shaft, the ring 55 and the lips 49, 51 being carried by a' resiliently axially displaceable sleeve 37 and the ring 57 being pressed against the ring 55 by a spring 65 to thereby form a mechanical seal and also urge the sleeve 37 axially to maintain the lips 49, 51 in contact with the conical surface. The sleeve is slidably sealed to a bore in the pump casing 35 by an 0-ring 39 and is connected to the casing 35 at the end adjacent the pump impeller 11 by a rubber diaphragm 41. The ring 57 is attached to a ring 61 sealed to the shaft by an O-ring 63, the ring 61 being axially displaceable on but rotatable with the shaft. The invention is shown applied to an immersion pump, the side of the impeller adjacent the diaphragm being open whilst the other side is closed by an annular disc 69. In operation, the diaphragm 41 is subjected to the vacuum developed on the suction side of the pump and the sealing pressure of the lips 49, 51 is reduced accordingly compared with that obtaining when the pump is stopped and the water pressure due to the immersion depth acts on the diaphragm. The casing 35 is surrounded by an oil reservoir 25.

Abstract: 1,024,065. Universal joints. LOHMANN & STOLTERFORT A.G. Sept. 27, 1963 [Oct. 20, 1962], No. 38133/63. Heading F2U. To facilitate dismantling a universal joint without separating axially the connected shafts, the joint includes a ring-shaped housing of such length that when removed from its coupled position, it leaves a sufficiently large space between the shaft ends for one or more resilient rings forming part of the joint to be taken out sideways. As shown, two rubber or like resilient rings 3, 4 each include a conical metal ring 3d, 4d and have hubs 3a, 4a bolted to the hub 2 of a shaft 1. Rigid rims 3c, 4c surrounding the resilient rings 3, 4 are bolted to a radially inwardly directed flange 5a of a ring-shaped housing 5, having a radially outwardly directed flange 5b bolted to a flange 7 fast with a shaft 6. The length of the housing 5 and the spacing between the shafts 1, 6 is such that, having removed the housing, the bolts securing the hubs 3a, 4a to the shaft hub 2 can be taken out and the resilient rings 3, 4 slidden away sideways from between the shaft ends. In one modification, two universal joints according to the invention are connected in series, Fig. 2 (not shown), by bolting their radially outwardly directed flanges 5b together. In another modification, Fig. 3 (also not shown), the outer ring of the resilient rings are bolted to the radially outwardly directed flange of the housing, which has its inwardly directed flange bolted to the second shaft.

Title: Precipitation of a layer of material
IPC: B01D46/22
Filed: 1973-08-13
Abstract: 1414053 Removing fibres from gas stream ROCKWOOL AB 13 Aug 1973 38209/73 Heading BIT [Also in Division D1] Resin-coated mineral fibres are delivered in an air stream 12 to the upper run of endless metal filter conveyor 15 which carries the resulting fibrous batt rightwards, and air containing fine fibres which have penetrated the bond is recycled from suction box 23 through tube 29 to a downstream part of the batt which then retains the fine fibres. In Fig. 1 (not shown) air is recycled to a chamber opposite a third suction box (25) and passes through the whole batt thickness. In Fig. 2 the batt is divided by blade 40 and recycled air passes only through layer 42' and second conveyor 42, the layer 42' reuniting with the main batt at 53. This concentrates fine fibres on the top of the finished batt, but air can be divided and recycled through both halves of an equally divided batt, either inwards or outwards to concentrate fine fibres at the surfaces or in the centre of the finished batt. Baffle 13 eliminates large non-fibrous particles which fall from outlet 14. The resin in the batt is heat-cured downstream of 39.

Abstract: 360,728. Internal-combustion engine locomotives. MASCHINENFABRIK AUGSBURG-NURNBERG AKT.-GES., 7, Stadtbac,hstrasse, Augsburg,. Germany. Dec. 22, 1930, No. 38599. Convention date, Jan. 17. [Class 79 (i).] Comprises a locomotive having two or more internalcombustion engines, some of which, during normal running, drive the locomotive wheels directly, and others indirectly, wherein only the indirectly-acting engine or engines is or are supercharged. The indirectlyacting engine may drive the locomotive through any desired transmission means, as, e.g. toothed gearing, electric or pneumatic transmission. In the construction shown a two-stroke-cycle engine g drives the wheel axles i directly, and the other engine a drives an air-compressor b supplying compressed air to expansion cylinders f driving the axles. The upper ends bl of the compressor cylinders deliver air to'the cylinders f through a pipe 6 and a heater e heated by the exhaust gases in the exhaust pipe d of the main or indirectlyacting engine a. The lower ends b<2> of the cylinders b deliverair through a pipe l to the engine a either for scavenging, in the case of a two-stroke cycle, or for charging, in the case of a four-stroke cycle. The engine a is supercharged by throttling the exhaust at m. The exhaust air from the air cylinder passes to a receiver j supplying scavenging or charging air to the direct-acting cylinders g. A relief valve n connects the receiver j to the pipe l so that if the pressure in the receiver becomes excessive air can pass into the pipe l through the valve.
