Title: Improvements in or relating to gyroscopes
IPC: G01C19/38
Filed: 1958-05-09
Abstract: 865,642. Gyroscopic apparatus. ABBEY, A. (American Bosch Arma Corporation). May 9, 1958, No. 15009/58. Class 97(3) In a gyroscope having un equal compliances in at leas two mutually perpendicular directions so that under accelera tion the corresponding weigh shift causes an error producing torque, a cantilever beam- 1' carrying an adjustable weigh 21 is mounted on the rotor cas ing 15 with its longitudinal axis parallel to the axis of the rotor shafts 10, 11. The weight 21 is adjustable along beam 17 by engaging a threaded end portion thereof. As shewn the direction of maximum compliance is along the axis of the rotor shafts 10, 11, the compliance in the two mutually perpendicular directions being less but equal to one another so that the beam 17 is of circular cross section. If however the compliances in the two mutually perpendicular directions are not equal, the beam 17 is of rectangular crosssection, the stiffness of the beam in each perpendicular direction being inversely proportional to the stiffness of the system in that direction. In a modification a second compensator is mounted at the bottom of the casing and if beams of rectangular cross-section are used the stiffer axis of one beam is perpendicular to the stiffer axis of the other.

Filed: 1916-10-21
Abstract: 110,571. Scott, R. W. Oct. 21, 1916. Circular machines; knitting, methods of.-Relates to the production, on circular machines, of a longitudinal mark, wall or ridge resembling a mock seam which may extend through a section of spliced fabric, and consists in selectively raising one or more special needles n<1>, Fig. 1<r>, to receive a wrapping of auxiliary yarn t from a guide t<1> by relative movement between the guide and the whole circle of needles n, the wrapping being engaged with the fabric by knitting upon the needles n<1>. The auxiliary yarn may be cast off without knitting, as shown in Fig. 12, interknitted with the loops of the ground fabric as shown in Fig. 18, or knitted separately as shown in Fig. 22; also, the auxiliary yarn may engage the fabric in each course or intermittently to imitate a sewn seam. The invention is illustrated in connexion with the machine shown in Specifications 12722/13 and 102,711. Needles n<1>, Figs. 4 and 9, having specially short butts, are adapted to pass a depressing-cam 100 and take the auxiliary yarn f from a guide t<1> which is brought into operation against the action of a spring by an additional elevating movement imparted to a thrust bar controlling one of the main yarn guides. The cam 100 is carried by a spring arm 101, and is normally adapted to engage all the needle butts, but is held out of range of the butts of the needles n' by the engagement with a lug 107 of a lever 420 operated as described in Specification 10819/15. Where intermittent engagement of the auxiliary yarn is not required, the cam 100 is arranged to miss the butts of the needles n<1>, and the lever 420 is dispensed with. In splicing, the floats of splicing yarn s, Fig. 1, are deflected beneath a dial 5, Fig. 6, having a cut-away portion 20, so as not to interfere with the auxiliary yarn t. The needles n<1> may be isolated to receive the yarn t by elevating them above the remaining needles. Fig. 1<a> shows a stocking S having a mark or mockseam 2 in imitation of flat-fashionel hosiery, the mark 2 extending through a spliced portion h. Specification 11934/06 also is referred to.

Title: Improvements in the manufacture and production of valuable hydrocarbons
IPC: C10C1/20
Filed: 1929-05-15
Abstract: 313,123. I. G. Farbenindustrie Akt.- Ges. June 7, 1928, [Convention date]. Mineral and tar oils.-Valuable hydrocarbon products such as benzines, lubricating oils, &c. are obtained from tar, crude oils, &c. by subjecting the materials to a " condensation " treatment namely a treatment in which several molecules are combined by chemical reaction or by polymerization to form larger molecules, followed by a treatment with hydrogen at elevated temperatures and preferably under pressure and in the presence of catalysts. The condensation may be carried out by heating the materials in the presence of " condensing " catalysts, e.g. aluminium chloride, boron fluoride, zinc chloride, &c. or in the presence of gases having a '' condensing " action particularly gases containing oxygen, e.g. air, industrial waste gases steam, or gases containing compounds of sulphur or chlorine. Dehydrogenating catalysts, e.g. vanadium pentoxide may also be present. Air at 160-180‹ C. is led through a porous plate into an oil obtained by the destructive hydrogenation of brown coal and mixed with 5 per cent of vanadium pentoxide. The products are led with hydrogen at 430-450‹ C. and 200 atmospheres over a catalyst containing molybdenum, zinc, and magnesia. A lubricating oil having a flash point of 191‹ C, and viscosity of 14‹ Engler at 50‹ C, is obtained. A better yield is obtained if the pressure is increased to 1000 atmospheres. A heavy benzine of boiling point range of 180-250‹ C. mixed with water vapour is passed at 700‹ C. with high velocity of flow over an iron catalyst containing free alkali. The high boiling point products are treated with hydrogen at 1000 atmospheres and 430‹ C. in the presence of a catalyst containing molybdenum, chromium and manganese.

Title: Improvements in and relating to elastic fluid turbines
IPC: F01D15/02
Filed: 1920-06-07
Abstract: 168,675. British Thomson - Houston Co., Ltd., and Halliwell, R. F. June 7, 1920. Cooling parts.-In an elastic-fluid turbine provided with ahead and astern stages, the idle stage is prevented from overheating due to running in dead steam by providing valve-controlled passages between the two stages and the condenser, the valves being arranged to open automatically to establish connection between the idle stage and the condenser. The reverse rotation of the idle stage induces a reverse circulation of steam from the condenser through the stage which keeps it cool. A high-pressure turbine 1, Fig. 1, and a low-pressure turbine 2 are each provided with ahead and astern stages and passages 14, 15 controlled by spring-pressed valves 12, 13 connect the inlet ends of the ahead and astern stages of the high-pressure turbine 1 to the condenser 3. If steam is admitted into the ahead section of the turbine 1 through the inlet 4, the valve 12 is closed by the steam pressure acting against the spring, but the valve 13 remains open by the action of its spring and the circulation of cooling steam from the condenser 3 through the astern stage of the low-pressure turbine 2, pipe 8, astern stage of the high-pressure turbine 1, and passage 15 back to the condenser. Similarly, if steam is admitted to the astern sections of the high-pressure turbine 1 through the inlet 7, the valve 13 is shut automatically and the valve 12 opens to allow circulation of cooling steam in the ahead sections. The valves 12, 13 may be combined as shown in Fig. 2, being formed on one sliding-pieee so that pressure in the pipe 11 moves the valve to the left and closes connection between the pipe 11 and the passage 16 leading to the condenser but simultaneously opens connection between the pipe 10 and the passage 16. A handle 18 affords means for testing the freedom of the sliding valve.

Title: Improvements in or relating to alkylation of hydrocarbons
IPC: C07C2/62
Filed: 1939-05-24
Abstract: 529,194. Alkylating isoparafftns. TEXACO DEVELOPMENT CORPORATION. May 24, 1939, No. 15413. Convention date, June 18, 1938. [Class 2 (iii)] The loss of olefins is avoided in the alkylation of isoparaffins by means of olefins in the presence of concentrated sulphuric acid as a catalyst by separating the acid from the reaction product and contacting the separated acid with substantially olefin free isoparaffin to strip the acid of olefins prior to its discharge from the system. It is stated that the olefins absorbed by the acid probably alkylate the isoparaffin. The reaction of the present invention is preferably carried out in a continuous multi-stage countercurrent operation, using a multiple injection of olefins between stages, and the preferred source of olefins is the C 4  fraction of cracked hydrocarbons. In the figure isoparaffin introduced through line 1 is mixed in mixer 3 with used oxide introduced through line 8, and alkylation of the isoparaffin takes place. The reaction mixture passes through line 9 to settler 10 where the stripped acid separates and is removed through the line 12. The hydrocarbons in the upper part of the settler 10 are diluted with olefins introduced through line 14. The amount introduced is preferably such as to give an isoparaffin to olefin ratio of from 3:1 to 5:1. The isoparaffin -olefin mixture passes from separator 10 to the mixer 20 where it is contacted with partially spent acid introduced through line 22. After mixture the product passes to separator 25. After separation the now completely spent acid is passed back to the mixer 3 above referred to. In a similar manner the hydrocarbons pass through three other types of mixers and separators. In each case the acid being passed in from the set following until in the fifth stage fresh acid is used of 94 per cent. to 98 per cent. concentration. After passing from the fifth stage settler 54, the hydrocarbons enter mixer 58 where they are contacted with a neutralizing agent, and then a fractionator 68. The bottoms are withdrawn through line 72, and the overhead vapours pass to a secondary fractionator or stabilizer 75 to separate the motor fuel hydrocarbons and the gaseous hydrocarbons.

Filed: 1970-04-01
Abstract: 1310905 Watering plants W B CRANE Jnr 1 April 1970 [2 April 1969] 15447/70 Heading A1E A plant watering device which is responsive to the moisture content of the planting medium, e.g. soil 24, comprises a substantially airtight enclosure 13 defined by containers 11, 12, the soil 24 and plant roots 25 being contained in the container 11. A tube 27 is connected at one end via stopper 29 to an air chamber 13a and at its other end to a one piece porous sensing element 32 which is located in the soil 24. When the watering device is in use the enclosure 13 is filled with water through an opening 30 and the stopper 29 is replaced as shown. Assuming that the soil 24 is initially moist moisture will be extracted therefrom into the pores of element 32 which then acts as a closed valve and prevents the flow of air through tube 27 into chamber 13a. As the soil 24 becomes dry the pores of element 32 start to permit seepage of air through tube 27 into chamber 13a thus causing water to seep through a porous element 22 from reservoir 13 into the soil 24, which will again cause blockage of the pores of element 32. The pore size can be predetermined to suit the plant conditions. In a further embodiment, Figs. 2-3 (not shown) the receptacle (40) is inverted and is connected to a sensing element (50) by a tube (51) which is connected to a tube section in the receptacle (40). When air enters the receptacle (40) through tube (51) water is caused to flow gradually through outlet openings (46) located in the receptacle base into the soil. Plant pots (43) formed of porous material are located in the soil (42) and have capillary association therewith.
