Title: Improvements in or relating to turbine-driven centrifugal pumps for boiler feed systems
Inventor: LANG JOHN RUSSELL
IPC: F01D25/22
Filed: 1958-12-16
Abstract: 889,190. Lubricating bearings. WEIR Ltd., G. & J. Dec. 4, 1959 [Dec. 16, 1958], No. 40517/58. Class 12 (3). A turbine - driven centrifugal pump for a boiler feed system, comprises a turbine wheel 1 and a pump impeller 2 on a common driving shaft 3 mounted in bearings 4, 5 interposed between them, the bearings being lubricated with the boiler feed water and the turbine and pump being contained in a common casing 13, 19, 18. The bearings are of plastic or carbon. The axial thrust of the turbine is taken by a thrust ring 14 or, under certain conditions, by a thrust ring 16. Cool water is injected through a connection 20 by the bearings, some of the water passing to the turbine exhaust by way of passages 22, 23 and the rest to the pump suction chamber 11 leading from the feed water connection 12. If the temperature of the feed water passing through the connection 12 is low enough, the connection 20 may be omitted. Pressure in the space 11 then rises until the same quantity of water is flowing to the bearings as leaks between the impeller rings 7 and the wear rings 10. Since the whole assembly is enclosed in a single casing, the pump is suitable for dealing with radio-active fluids.

IPC: B22D7/12
Filed: 1960-11-25
Abstract: 903,534. Mould and core materials. DAUSSAN, H. J. Nov. 25, 1960 [Nov. 28, 1959; Feb. 24, 1960; Oct. 25, 1960], No. 40545/60. Class 83 (1). [Also in Group VIII] A screen for protecting the sides of an ingot mould from the splashing of the pouring jet is made by tightly rolling a strip which after insertion in the mould will unwind to an extent which leaves the ends of the strip superposed. A fire-proofed corrugated cardboard strip 1, Fig. 1, is reinforced with metal strips 3 and the ends BC bent so that when the coil I, Fig. 5, unwinds in the mould E<SP>1</SP> the ends engage, Fig. 7. The screen may be made of two strips A, Fig. 8. In a modification, Fig. 15, a loop 16 is attached to the strip and prevents complete unwinding of the coil. The loop 16 may retain the tight coils until the screen is inserted into the mould, e.g. as by the use of ties 26, Fig. 20, which are then freed by pulling to allow the screen to expand.

Title: Improvements relating to weighing apparatus
Inventor: CHILTON JOHN MOORHOUSE
IPC: G01G23/37
Filed: 1961-11-16
Abstract: 1,031,344. Selective signalling; multiplying- apparatus. W. & T. AVERY Ltd. Nov. 15, 1962 [Nov. 16, 1961], No. 40981/61. Headings G4A and G4H. A system for weighing a pre-set mixture of two ingredients includes a computing circuit for producing a count representing the total weight of the two ingredients from the weight of some of the first ingredient and the pre-set composition of the mixture, whereby the second ingredient can be dispensed into the same scalepan as the first ingredient until the computed total weight is reached. The computing circuit operates as follows. The nines complement of the weight x of some of the first ingredient is entered into a first counter. Clock-pulses are then applied to the first counter which produces an output pulse when it becomes full (after x clock-pulses). Each output pulse from the first counter performs two functions (a) it is entered into a second counter which has previously been set to the nines complement of 100 + r, where r% is the desired percentage composition, and (b) it causes the nines complement of the weight x to be re-entered into the first counter. This process repeats until the second counter becomes full (after 100+r), whereupon the supply of clock-pulses to the first counter is discontinued. The total number of clock pulses passed to the first counter will then be x (100+r) and these clock pulses also pass to a divide by 100 counter and then to a third counter. The final result is that the third counter contains a count of x (1 + #-#) which is the weight x plus r% of x.

Title: Improvements in or relating to heat exchangers
Inventor: PATTEN THOMAS DIERY
IPC: F28D9/00
Filed: 1959-12-02
Abstract: 901,914. Plate heat exchangers. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Dec. 22, 1960 [Dec. 2, 1959], No. 41030/59. Class 64 (3). A heat exchanger comprises stacked plates, the plates being embossed with rows of foursided pyramidal projections and adjacent indentations resulting in the plates being corrugated in two directions at right angles to each other, such that the cross-sectional flow area is constant. Plates 1 consist of thin metal sheets embossed with the four-sided pyramids having rounded crests. Every sheet may be embossed or the exchanger may consist of alternate flat and embossed sheets. If every sheet is embossed they may be supported by means of rods 3 drilled through holes 2 such that the projections of one plate come into contact with the indentations of the next. If no rods are used, then either the projections must be affixed to the indentations of the adjacent plate or spacers must be placed between the edges of the plates. If alternate flat sheets are used, then the assembly does not require such accurate alignment of the plates as when only embossed sheets are used, but the method of supporting is the same. The plate interspaces are made into ducts by sealing certain lengths of the plates by sealing bars 4. Various types of sealing bars are disclosed in Fig. 5 (not shown).

Title: Building structures
IPC: G21C9/004
Filed: 1965-09-28
Abstract: 1,096,363. Pressure doors. UNITED KING- DOM ATOMIC ENERGY AUTHORITY. Sept. 28, 1965 [Sept. 28, 1964; April 5, 1965], No. 41260/65. Heading F2P. A wall opening of a pressure vessel comprises a framework F defining a plurality of apertures which are closed by displaceable panels P, the panels being held close to the apertures by means H which responds to displacement of one of the panels so that displacement of one panel effects displacement of the remaining panels. The framework is in the form of a rectangular grid and is closed by a number of similar rectangular panels. In the embodiment shown in Fig. 2, each pair of panels 15 and 16 have their outer edges secured behind the webs 12, 13 of the frame F, whilst gaps between their inner edges and a supporting member 14 in the form of a bar across the full width of the panel are sealed by adhesive tapes 17, 18. The means H is in the form of a vacuum panel 19 of smaller area than the panels 15, 16, and having abutments 20 which press against the inner edges of the panels. Attached to the back of the panel 19 is a sealing ring 22 forming a vacuum chamber which is evacuated through channels 30, 24 in the member 14 and which connect with similar vacuum chambers on vacuum panels which hold the remaining displaceable panels to the framework and to a vacuum pump. Atmospheric pressure (on the left-hand side of Fig. 2) retains the panel 19 in position against panels 15 and 16 which are also subject to a pressure in the chamber (on the right-hand side of Fig. 2) normally less than is required to displace them outwards. If the pressure in the vessel rises in excess of the normal sufficiently to blow out any one panel, the vacuum in the chamber 23 is broken. The chamber 23 is interconnected to all the other vacuum chambers so that all remaining panels are also displaced. In other embodiments (Figs. 3 to 5, not shown), the vacuum chambers are formed around the periphery of the back surface of each panel so that they are able to retain the panels by suction against flanges which protrude inwards around the periphery of each opening in the framework. A member is provided to clamp the panels to the frame temporarily whilst the vacuum is being formed. Alternatively, the holding means may consist of a series of electromagnets so interconnected that when the excess pressure in the vessel displaces one panel the electromagnets on the remainder become inoperative.

Title: Improvements in and relating to Tumbling Media
IPC: B24B31/14
Filed: 1966-09-15
Abstract: 1,163,739. Tumbling media. MINNESOTA MINING & MFG. CO. 15 Sept., 1966 [16 Sept., 1965], No. 41323/66. Heading C4V. A process for producing tumbling media barrel finishing comprises depositing droplets of flowable permanently settable composition on a substantially flat surface, hardening the composition and thereafter collecting the hardened chips on the surface, the composition having, during depositing, a viscosity between 500 and 30,000 poise measured on a rotating spindle viscometer at 2 r.p.m. Abrasive particles in the composition may be finely divided alumina, silicon carbide, titanium carbide, zirconia and silica. These particles may be angular in shape to provide abrasiveness and have an average size range of 1 to 500 microns. The compositions may contain 30 to 75% by weight of the abrasive particles. The binding materials may be vitrifiable ceramics such as clay or frit-containing compositions which are mixed with water or a fugitive organic binder of desired consistency prior to use. The shapes are dried into formation to harden them sufficiently to permit firing in a kiln. The shapes are generally fired to the softening point of at least some of the constituents of the ceramic composition in order to cause some degree of vitrification. Other binders include the cementitious type such as Portland cement, which attain a permanence upon air curing. Suitable resinous binding materials include polyester resins, polyester styrene copolymers, phenolics and epoxy resins. Such resins are generally mixed with the abrasive particles and a suitable catalyst and hardening may be accomplished by passing the shapes through a heated oven or a radiating chamber wherein the resinous constituent is polymerized or cross-linked. The shape of the media may be varied by having orifices with configurations other than circular, for example, rectangular, triangular, elliptical and indented. The collecting surface may be quilted, ribbed, dimpled or corrugated. This surface may consist of a moving belt which conveys the shapes through the hardening zone.

The piston 10, attached to a lip seal 13, is connected by a hollow piston rod 10 to a handle 12 by which the pump is reciprocated. When the handle is pulled air is sucked from an orifice (5) in the mattress, Fig. 1 (not shown) through a further orifice 20 in the sleeve 9 of the support to the chamber 19, and when the piston is pushed back a non- return valve at (5) closes and the pressure in chamber 19 builds up forcing the lip seal 13 to open and allow the air to pass through: an aperture 14 in the hollow piston rod from which it passes out of an aperture 17 at the end of the rod. The poles 6 may be integral with the mattress, or detachable for ease of transport to the site of an accident, they may also be formed from two or more parts, one of which contains the pump. The mattress is inflated through a further aperture (5).

Abstract: 1398944 Measuring current CONTRAVES - ANTRIEBSTECHNIK AG 5 Sept 1973 [13 Oct 1972] 41683/73 Heading G1U [Also in Division H2] The direct current output of a rectifier assembly D1-D6 is measured by using at least two transformers 20, 30 in separate current paths such that all the rectified current flows through the primary windings. The transformer secondary windings have individual capacitive loads 22, 32, rectifying diodes 21, 31 and feed a common load impedance 40. The rectified current I 1  flows through a D.C. motor M and its magnitude is controlled by adjusting the firing angle of the S.C.R. assembly D1-D6 which full-wave rectifies the three-phase input R,S,T. A second rectifying assembly provides an opposite current I 2 , which is similarly measured. Adjustment of the relative values of 1 1  and 1 2  enables the motor M to be reversed and controlled in speed.

Title: Method of producing poly olefines of high whiteness
IPC: C08F10/00
Filed: 1961-11-23
Abstract: Polyolefines of high whiteness are prepared by polymerizing olefines in the presence of liquid diluents by means of mixed catalysts containing titanium tetrahalides and organo-metallic compounds of Group I to III of the Mendel<\>aeeff Table, under conditions of pressure and temperature such that the polymer is separated in the liquid as a solid phase which is then separated and washed out, characterized in that the polymerization is effected in the presence of hydrogen at a constant olefine-hydrogen partial pressure ratio, the hydrogen partial pressure being kept at less than 10% of the olefine partial pressure.  Ethylene and its homologues are particularly suitable monomers.  Suitable organo-metallic compounds mentioned are aluminium-organic compounds having 1 to 3 alkyl, aryl and/or cycloalkyl groups and up to 2 halide atoms in the molecule e.g. aluminium trialkyls, triaryls, tricycloalkyls, dialkyl aluminium halides and alkyl aluminium sesquihalides. Liquid hydrocarbons mentioned are butane, pentane, hexane, isopropylcylohexane, petrol and diesel oil fractions.  Polymerization temperature is from 20 to 200 DEG  C. and pressure is ordinary or slightly elevated.  The polymerization may be carried out continuously or discontinuously in the presence of an inert diluent. The hydrogen is advantageously mixed with the olefine; in the case of a continuous process it can be introduced to the cycled gas.
