Title: Improvements relating to safety arrangements for the drives of haulage and conveyor installations operated through the medium of controlled electric discharge devices
IPC: B66B1/12
Filed: 1936-06-16
Abstract: 469,156. Control of motors. SIEMENSSCHUCKERTWERKE AKT.-GES. June 16, 1936, No. 16785. Convention date, Aug. 20, 1935. [Class 38 (iii)] In a safety arrangement for the drive of a conveying or hauling installation, the driving motor of which is supplied with current from and when acting regeneratively supplies current to an A.C. network through the medium of electric discharge devices which are controlled in their operation, for example, by means of grids or other controlled electrodes, the operation of the safety arrangement first operates a safety brake for the conveyer or hauling drive and the discharge devices are then switched off by operation of the brake, so that they are not switched off until after the brake has been operated. The invention is particularly applicable to systems having two discharge devices in cross-connection, and the contacts or the like operating to switch off the discharge devices only after operation of the brakes are operatively arranged on the safety brake or on devices whose operation is controlled by operation of the brake. The brake first causes the switches on the D.C. side of the discharge tubes to be opened and switches in the A.C. circuit are then opened by auxiliary contacts either on the brake or on the D.C. switches. In an emergency, the A.C. switches may be opened without reference to the safety brake, the holding coils of the D.C. quick-acting switches and of the brake magnets being connected behind the A.C. switch, so that when the latter is opened, the D.C. switches and the brake are operated. Upon switching-in the installation, the switches in the D.C. and A.C. circuits which are dependent on the brake are short-circuited by a starting relay which may be subsequently cut out by a contact controlled by the brake. Should a short-circuit occur, for example, in the transformer supplying the discharge devices; the A.C. switches are released. The control devices may be divided into groups, one group serving to switch off at once the discharge devices, while the other group or groups switch off the devices after a time interval or upon the attainment of a certain working condition, e.g. the arrival of the conveyer bucket at its upper stopping position. The invention may be applied to converter arrangements having only one group of discharge vessels, which may be controlled by switch means to operate either as rectifier or inverter and conversion may be effected either from A.C. to D.C. or between alternating currents of different frequencies.

Title: Improvements in or relating to combined alkylation and isomerization processes
IPC: C07C7/00
Filed: 1944-09-06
Abstract: In a combined process of isomerizing normal paraffins using a metal halide catalyst, and alkylating the isoparaffins with olefins using sulphuric acid as catalyst, product from the isomerization stage is treated with an alkaline reagent, alkylated product is then added to the mixture and the whole treated with additional alkaline reagent, the hydrocarbon phase then being separated and distilled.  Corrosion of the distillation apparatus is thereby avoided.  Products from the isomerization of paraffins with a volatilizable metal halide and a promoter such as hydrogen halide pass to a fractionator 12 wherein hydrocarbons are separated as overhead from a liquid residue equivalent to 2-20 per cent of the feed, containing the metal halide. The hydrocarbons pass to condenser 14, accumulator 15, and thence to hydrogen chloride stripper 17, part being returned to the fractionator by line 18.  Isomerized product leaves by lines 25, 26 for further separation of iso- and normal paraffins.  The liquid residue 20 is mixed with alkaline reagent in line 27 and mixer 28, alkylate from the alkylation of isoparaffin with olefine in presence of sulphuric acid is introduced by line 30, and additional alkali by line 31.  The <PICT:0588835/IV/1> combined streams pass to mixer 32, thence to settler 34 where a hydrocarbon phase separates and is fed to fractionator 36 yielding isoparaffin as overhead, alkylate as bottoms, and normal paraffin as a side stream.  The alkali phase is fed to line 27 or part to line 27 and part to line 29 for treating the isomerization residue 20 or combined isomerizate and alkylate. Alkali is periodically discarded by line 45 and fresh alkali added by lines 49 and 27 or 31.  Alternatively, fractionator 12 may be byepassed, isomerized product passing directly to stripper 17 and the stripped hydrocarbons to line 21 via line 55.  Sufficient alkali, e.g. 10 DEG  p  B<\>ae sodium hydroxide, should be used to neutralize the acidity of isomerizate and alkylate.

Abstract: 603,152. Washing gases with liquids. FLEISHER, W. L. Sept. 6, 1944, No. 17040. [Class 55(ii)] In a gas-conditioning apparatus, a cell unit comprising a plurality of parallel strands is supported at an acute angle to the horizontal and intermittently supplied with liquid which washes the cell and leaves a moisture film on the strands for removing dust from the gas passing through them. As shown in Fig. 1, the cell 10 comprises two layers 15, 20 of parallel glass strands spaced by a few random diagonal strands, the layers being pressed together by external wire screens 13 and 21 and having a resilient corrugated wire mesh 17 between them. The cell may be supported as shown in Fig. 2, and intermittently supplied with liquid from a tank 40 periodically emptied by a syphon 41. The liquid is evenly distributed over the top of the cell by a trough 48, Fig. 4, the liquid flowing down pipe 43 and out of a T-head 52 onto a wire mesh retarding screen 51 and then falling in a narrow sheet-like stream through a small slot 50. Other means may be used for intermittently supplying the liquid e.g. the trough may be made to tilt and discharge liquid when full. Two or more cells may be placed end to end in which case an additional retarder is provided in the trough, or a second cell may be placed underneath the first but extending in the opposite angular direction, the liquid flowing from the top cell directly on to the top surface of the bottom cell. Specification 516,646, [Group IX], is referred to.

Title: Integrated semiconductor rectifiers and processes for their fabrication
Inventor: MCCANN J A
IPC: H01L23/36
Filed: 1971-05-25
Abstract: 1355702 Semi-conductor devices GENERAL ELECTRIC CO 25 May 1971 [27 July 1970] 17069/71 Heading H1K In a process for producing integrated rectifier units a wafer of semi-conductor material is provided with regularly spaced parallel bands of opposite conductivity type in both major faces so that opposed bands are aligned and are of opposite conductivity type to form P-N junctions, grooves are formed in one face between adjacent bands to a depth sufficient to intersect the junctions, grooves are formed in the other face perpendicularly to the bands to a depth sufficient to intersect the junctions, and the wafer is subdivided along selected ones of the grooves to form units each containing at least two P-N junction rectifiers. A lightly doped N (or P)-type Si wafer is subjected to planar type-processing to form a pattern of parallel N + and P-type bands in both major faces. Alternatively a single masking and diffusion step using GaAs as the impurity source may be utilized to form all the bands simultaneously. Parallel grooves are formed in one face to isolate the bands from one another and grooves are formed in the other face parallel to one another but perpendicular to those in the first face to form columns of alternate type segments, apertures being formed where the grooves intersect. The grooves may be produced by sawing or by etching for which strip shaped contacts may be applied to act as the mask. The wafer is then subdivided along appropriate grooves to form integrated units. The unit shown in Fig. 8 is a single phase full wave bridge rectifier which is utilized by connecting output conductors to N+ and P-type regions 202, 204 and input conductors to the pairs of adjacent N + and P-type regions 208A- 206A, 208B-206B respectively. The lateral junctions between these adjacent regions are shorted by the contacts. By dividing such a unit along the groove parallel to the Y-axis, units comprising two diodes are formed. By utilizing a segment of the wafer extended by a further pair of diodes (dividing at the next groove) in the X-direction a three phase bridge rectifier may be formed. The units may be mounted on a heat sink comprising a Cu substrate by an insulating layer of aluminium nitride, berrylia, alumina, boron nitride or a synthetic resin. The unit is surrounded with a glass passivant which together with the electrodes encapsulates the device. Alternatively, the passivant may be an oxide, nitride, silicone varnish or rubber, or epoxy resin, the device being mounted in a housing. The starting wafer may be uniformly doped and a single diffusion to form bands of the opposite conductivity type used. The bands may also be formed by alloying. The grooves may be passivated before subdivision of the wafer.
