Abstract: 1,031,070. Mounting electrical equipment. M.E.L. EQUIPMENT CO. Ltd. Feb. 18, 1965, No. 7069/65. Heading H1R. In an electrical assembly, for example, a crystal filter, an electrical component having a substantially rectangular metal housing, the width of which is at least twice its depth, and leads to the component which project from an end of the housing in the direction of the length thereof, is secured to a support member parallel to the major surfaces of the housing. The support member, or a surface part thereof, may be of conductive material, the housing being soldered thereto. Further, similar component housings may be bonded to the reverse side of the support member and/or in layers on the first housing. In Fig. 3 (not shown), a component housing 1 having a lip 12 is maintained parallel to a support 7, to which it is soldered at 8, by a corresponding pip 13 pressed out of the support 7. In Fig. 4, a channel-shaped support 17 carries housings 31... 35, and is itself soldered to the base 23 of an earthed casing 40.

[Class 2 (iii)] In the alkylation of isoparaffins with liquid olefines, the hydrocarbon mixture containing the olefines and normal and iso paraffins is freed from the normal paraffins before the alkylation. In the Figure a pentane-amylenefraction is distilled in a column 3 to separate a bottom product, containing the normal pentane, from the amylenes and isopentane, which are condensed in a condenser 6 and fed first to a mixer 11 and then to an emulsion of hydrocarbons and sulphuric acid circulating through pump 16, cooler 17 and time tank 18. Isobutane feed is introduced through line 12 and recycled isobutane through line 13 to give excess of isoparaffin over the amylenes. A controlled amount of reaction mixture is withdrawn through line 21 to a separator 22. Fresh acid is introduced through line 26 and the hydrocarbon products are debutanized in a still 28 and scrubbed with caustic alkali in a scrubber 33 before passing to a storage tank 37. The following alkylation catalysts are mentioned : halogensulphonic acids, boron fluoride, boronfluoride-sulphuric or phosphoric acid mixtures, aluminium chloride and organic and inorganic aluminium chloride complexes.

Abstract: 1481273 Electro-phoretic analysis SHIMADZU SEISAKUSHO Ltd 21 Feb 1975 [28 Feb 1974 7 March 1974] 7360/75 Heading G1N Apparatus for electro-phoretic analysis of ions and like electrically charged particles comprises a capillary tube in which a liquid column comprising different ions is formed, means providing a potential gradient between the ends of the tube to separate the ions into zones, means for detecting potential gradients of the ions in the different zones and either (a) a circuit for calculating the ratio of the potential gradient of one ion to that of each of the other ions or (b) means for also measuring the migration speed for each ion and circuitry for dividing the speed by the potential gradient to produce a measure of the ion mobility. As described, a sample to be analyzed is inserted into a PTFE tube between a leading electrolyte, high mobility, and a terminal electrolyte, low mobility. A potential is applied between the ends of the column and potential gradient is sensed by two longitudinally spaced electrodes flush with surface of a bore in a chamber located in the tube. The potential gradient is converted to a frequency and transmitted via an optical link before reconversion to a voltage for recording or processing. The measuring section of the tube is maintained at constant temperature. In the embodiment shown in Fig. 4, the potential gradient of the leading electrolyte A is detected at d and stored at f. The potential gradients of the unknown ions C , D , E are consecutively detected at e, compared with that of A at g, and the value recorded at h. Alternatively, only one detector may be used, the value of A<SP>-</SP> potential gradient being stored and compared with those of C , D and E . In the other embodiment Fig. 6, the potential gradient for each ion is measured at d, and stored at f. The ion speed is determined by the time for its boundary to move from detector 61 to detector 62 and is stored at 65. Circuit g calculates mobilities which are recorded at h. Alternatively, one of the boundary detectors 61 or 62 may measure the potential gradient.

Title: Improvements in or relating to apparatus for regulating the output of dynamo-electric generators
IPC: H01R39/42
Filed: 1942-06-02
Abstract: 556,501. Automatic control systems for D.C. generators. STACKPOLE CARBON CO. June 2, 1942, No. 7486. Convention date, June 21, 1941. [Class 38 (iv)] Voltage, current.-The output of a dynamo 13 is regulated by a motor 1 the armature of which is in series with the field winding 16 of the dynamo, its own winding being connected across the dynamo output leads. The motor is held stationary by braking until the dynamo output reaches a value at which a solenoid, in shunt or in series with the output leads, reduces the braking. This solenoid then varies the braking so that the back e.m.f. of the motor regulates the dynamo field as required to maintain the output constant. When the output tends to exceed a limiting value the solenoid lifts a brush 7 on the motor commutator to interrupt the dynamo field circuit and prevent further rise in output. As shown in Fig. 2 a spring 9 adjustably presses a brush 7 on the motor commutator to determine the output required to start the motor, and the solenoid 21 through a back coupling progressively relieves the brush tension and eventually lifts the brush. In a modification a shunt connected solenoid regulating output voltage operates upon a brake block on a drum coupled to the motor spindle, a blade spring pressing on the block being extended to engage brush-lifting means. A series connected solenoid lifts another brush to limit output current.

Title: Improvements in or relating to marine steam propulsion plant
IPC: F22G5/16
Filed: 1944-04-24
Abstract: 575,918. Steam boilers; superheaters. BABCOCK & WILCOX, Ltd., and ZOLLER, R. E. April 24, 1944, No. 7564. [Classes 64 (iii) and 123 (iii)] The temperature of steam from a boiler, or boilers, of a marine propulsion plant including ahead and astern prime movers is controlled by a de-superheater or heat-exchanger which is associated therewith and is maintained at a temperature sufficiently high to permit its immediate use when superheated steam is required for astern working. The de-superheater preferably comprises an enclosed casing 5, having an inlet 10 and outlet 12 connected respectively by a downcomer 48 or 48<1> and riser 47 or 47<1> with the steam and water spaces of the steam and water drum 30 or 30<1> of the boiler, and locating main and auxiliary banks 1, 2 of U-shaped tubes which open into, a head 4 at the one end thereof. This head 4 is divided by walls into a steam inlet chamber 24 with port 27, a main steam outlet chamber 25 with port 28 and an auxiliary steam outlet chamber 26 (not shown) with port 29, the inlets and outlets of the main tubes 1 opening into the chambers 24, 25 respectively and the inlets and outlets of the auxiliary tubes into the chambers 25, 26 so that steam will flow from the port 27 through the chamber 24 and tubes 1 to the chamber 25, from which it may pass through the port 28 or flow through the tubes 2 to the chamber 26 and port 29. As shown, the inlet port 27 leads from piping 34, 35, 37, 38 between superheaters 31 or 31<1> and a common main 39, the port 28 is connected to the steam main 39 through pipes 40, 42, and the port 29 by pipes 43, 45 to a pipe 46 supplying auxiliary apparatus, for example, oil heaters and atomizers requiring steam at a temperature below normal superheat temperature. The arrangement is such that the continuous flow of steam from the superheater to the auxiliary pipe 46 through the de-superheater 5 will maintain normal circulation through the latter of water and steam from the downcomer 48 to the riser 47, and, therefore, normal temperature during ahead working of the plant when the de-superheater is by-passed by shutting a valve 41 in the pipe 40 ; for astern working a valve 36 in the pipe 35 is shut and the valve 41 opened. The auxiliary tubes 2 and chamber 26 may be dispensed with, in which case the port 29 opens from the main steam outlet chamber 25 ; alternatively the tubes 2 may be associated with a separate inlet chamber, as well as the outlet chamber 26. The temperature of the de-superheater may also be maintained by locating it in a by-pass parallel with the main leading to the ahead turbines, or by associating it with the wall cooling tubes or the boiler furnace.
