Abstract: 1484315 Nuclear reactor pressure vessels HOCHTIEF AG FURHOCH UND TIEFBAUTEN 14 Oct 1974 [24 Oct 1973] 44929/74 Heading G6C A composite concrete-and-steel pressure vessel is constructed so that, upon raising to operational pressure and temperature, stressing of an inner steel membrane is below the elastic limit of the steel, the membrane 6 being secured to an insulating layer 2 within an outer concrete wall 1 by fastening elements each comprising a radial anchor sleeve 7 slidably receiving an anchor member 8 with a stop flange 10. The concrete wall 1 is lined internally by steel 3 and has embedding cooling ducts 4; the insulating layer 2 is, e.g. of low-thermal conductivity concrete blocks 2a, 2b. In the inoperational state, a span 19(of dimension # r ) exists between the outer surface of the membrane 6 and the inner surface of the layer 2. Upon raising the vessel to operational pressure, the radius of the membrane increases by #r whereby the membrane 6 contacts the insulating layer 2. In detail, the membrane 6 mounts spring members 11 which bear against the inner surface of the layer 2. The anchor sleeves 7 are secured in the blocks of layer 2. Flanges 10 limit relative movements between the anchor sleeves 7 and anchor members 8. The space 19 can be filled with a suitable compressible material. The membrane 6 may comprise vertically arranged sections (6a, 6b, Fig. 2, not shown) welded together at transverse flanges (12) in order to enable it better to withstand axial stresses. The layer 2, the blocks 2a, 2b of which are wedgeshaped in plan, is retained to the steel lining 3 by securing bolts 14, nuts 16 and plates 17 anchoring the blocks 2b; blocks 2a are, then, retained by the wedging action of blocks 2b.

Title: Fluid logic elements
IPC: F15C3/00
Filed: 1972-09-29
Abstract: 1384140 Fluidic elements; data storage apparatus S LEKARSKI P HARDY L HARDY and J GACHOT 29 Sept 1972 [5 Oct 1971] 45001/72 Addition to 1360823 Headings G4P and G4B [Also in Division F2]  A fluid logic element includes a chamber containing a valve member which is movable by fluid pressure. The member experiences magnetic attraction towards one or more walls of the chamber. The chamber has an opening in which a second valve member is mounted. Movement of the first member changes the position of the second member, to prevent or allow fluid flow through the opening. The first valve member 113, Fig. 1, is of elastic material containing permanently magnetized material and is secured by a rigid plate 114 carried on piston 115 in chamber 106. Wall 101 of the chamber is of magnetic material. When fluid is admitted to duct 117 membrane 103 moves piston 115 upwards until member 113 seats against annular shoulder 121. In this position it has raised second valve members, of which one 125 is shown in opening 123, to allow fluid to flow from duct 126 to outlet duct 127. If the wall 107 of the chamber is non-magnetic, when the pressure in duct 117 falls the attraction between member 113 and wall 101 moves the piston down, so preventing further fluid flow from 126 to 127. In this case the element provides the AND function. On the other hand, if wall 107 is of magnetic material member 113 is attracted to it when raised, and remains in this position when the pressure in duct 117 falls i.e. the element is bi-stable. In this case member 113 can be returned to the position shown by applying fluid pressure to duct 120, causing membrane 112 to press disc 118 down on the top of piston 115.

Filed: 1971-09-20
Abstract: 1370886 Valves JAMES HOWDEN & CO Ltd 20 Sept 1971 [26 Sept 1970] 45970/70 Heading F2Y A liquid seal for a gas pipe comprises a vessel 3 containing liquid 4 and divided by a partition 6 into chambers I and II, two Venturi devices 13, 15 being arranged so that gas flow in the outlet 12 reduces the pressure in the chamber II and hence the liquid level in the chamber I to uncover the lower end of the gas inlet 9. Initial gas flow bubbles through the liquid to the Venturi devices but return flow is prevented. If the liquid level is sufficiently reduced to permit gas to flow under a baffle 11, gas enters the throat of Venturi 15 and reduces the flow to the throat of Venturi 13. Resistance to flow is thus reduced and not increased as it would be if only one Venturi were provided. Specification 1,165,821 is referred to.

Abstract: 1492585 Heating ceramic articles AUTOMATISME & TECHNIQUE 28 Oct 1974 [31 Oct 1973 18 Sept 1974] 46483/74 Heading CIJ [Also in Divisions H5 and F4]  A plant for heating and fritting ceramic articles a has a first furnace 3, which may be a conventional electric resistance oven, in which the articles are heated to around 1000 C., at which they are susceptible to heating by dielectric loss by microwaves, before further heating to the fritting temperature by microwaves in a waveguide 11. In the plant shown, small ceramic articles a are placed on a first conveyer 2 to be heated in furnace 3. Before entering wave guide 11, at 10 articles a are placed on discs of relatively cold alumina, preferably with an interposed insulating layer of expanded alumina, and covered with a protective shield b also of relatively cold alumina. The shielded articles pass through waveguide 11 where microwaves pass through shield b and support 9 without loss, to heat the articles. Shield b and plate 9 contain thermal radiation from articles a, to protect waveguide walls and keep articles a hot. After leaving waveguide 11, the shields and plates are returned to entrance 10. Their temperatures are regulated to some suitable value during this time to avoid thermal shock at 10 when articles a are enclosed. The temperature of microwave heated articles may be measured by means of their absorption of further microwaves in a chamber (1016, Fig. 5, not shown) after the heating waveguide 11 or between two heating waveguides when two are used. This temperature is used to control the microwave energy supplied. The energy absorbed is adjustable by tilting or oscillating the waveguide so that the path of articles a is not along the axis of the waveguide, the micrwaves being in TM010 mode, or by adjusting the voltage supplied to the microwave generator, magnetron or klystron, or the proportion of each cycle when energizing pulses are supplied to the generator. Refractories mentioned are oxides of aluminium, barium, beryllium and zirconium.

Abstract: 1525274 Memory testing INTERNATIONAL BUSINESS MACHINES CORP 17 Nov 1975 [20 Dec 1974] 47215/75 Heading G4A A memory array includes address AR and data DR registers in the form of feedback shift registers which are arranged so that a test pattern may be shifted serially into the two registers, SCAN IN, and a comparator 13 arranged to compare the array outputs with the data register outputs. The arrangement is described in connection with an LSI memory device in which the inputs to the memory array normally pass through on-chip logic from the device inputs although it is stated that a memory array with directly accessible inputs may also be used. In either case an input SCAN IN is provided which, under the control of a control signal CONTROL, is used serially to shift a test pattern through the address and data registers which are formed of master/slave flip-flops. The pattern may be shifted right through the registers, the output SCAN OUT being compared with the input SCAN IN to test for faults. Alternatively when the registers are loaded the CONTROL signal is changed to complete feedback loops via exclusive -OR gates EO for each register. The two registers are then shifted and pass through a cycle of states so that particular data items are stored in each address. By comparing 13 the array output with the data register output faults in the array may be located. By using signal G2 the data register produces complementary outputs so that the array can be checked for the storage of 1's and 0's. Pseudorandom patterns may be fed into the address and data registers which are then shifted 2<SP>n</SP> times to produce a large number of test patterns from a single input sequence.
