Title: Improvements relating to heat exchangers particularly for nuclear reactors
Inventor: HUTCHINSON WILLIAM GEORGE
IPC: F28D7/06
Filed: 1962-10-17
Abstract: 985,464. Tube-type heat exchangers. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Oct. 17, 1963 [Oct. 17, 1962], No. 41045/63. Divided out of 985,463. Heading F4S. A heat exchange system includes a number of tube units each with inlet and outlet headers 22, 23 for one fluid (the secondary fluid) flowing through tubes 50 (shown as U-tubes), and a surrounding shell 48 having an inlet port 51 for another fluid (the primary fluid) flowing over the tubes. In the unit shown the primary fluid passes out of the shell through ports 52. In the arrangement according to the invention all the units project downwardly from the floor of a main header 41 (Fig. 1, not shown) common to all the units, with the ports 51 opening into the header space and with each shell 48 extending out of the header through a corresponding aperture in the header floor and being sealed around said aperture. Each sealing means shown comprises a ring member 53 joined to the shell by a flexible bellows 54 so as to be movable longitudinally of the shell. Linkage 55 including a rocker arm 56 is actuable by a screw and nut adjustment 57 (Fig. 4) operable from outside the heat exchanger unit to move the ring 53 into sealing engagement with the header floor. The unit shown is of rectangular cross-section (Fig. 3, not shown) and the primary fluid flow is in two passes separated by a baffle 49. The primary and secondary fluids flow in contraflow in each pass. In a modification described (Figs. 5, 6, not shown) the unit is cylindrical, the U-tubes being arranged in an annular bank each with one limb in a first pass for the hottest primary fluid and defined by a tubular baffle, and another limb in the second pass formed by the annular space around the baffle. In this construction the primary fluid inlet port 51 is connected to the interior of the baffle by a short duct 59 (Fig. 6, not shown). In a further alternative a once-through flow path may be provided for the primary fluid by a shell of U-shape with one limb shorter than the other. The heat exchanger system described is associated with a nuclear reactor in which the primary coolant is a liquid metal flowing in a cycle through the reactor and heat exchanger units, the circuit including a reservoir in which the lower ends of the units are immersed. Hot liquid from the reactor passes into the main header and thence through the units 21, inlet ports 51. The heated secondary coolant from the units 21 passes in known manner to other heat exchangers (not shown) for generating steam.

Patent GB-1048088-A (GB)
Title: Surgical articles
IPC: C08G63/08
Filed: 1963-10-18
Abstract: Absorbable surgical sutures which may be used to form meshes, artificial tendons, staples and cartilage material comprise a sterile oriented synthetic polylactide having a viscosity of at least 1.0 at 0.1% by weight concentration in benzene at 25 DEG C. and being such that it shrinks in length less than 15% when immersed in water at 77 DEG C. for 5 minutes.  Sutures may be prepared by forming the polylactide by heating lactide and catalyst and then converting the polymer to filaments by spinning from the polymer melt or solution. The polymer may be extruded through a spinneret, after which the resulting filaments are drawn to at least 4 times their original length, annealed at 60-150 DEG C., while held taut, until they show less than 15% shrinkage when immersed without tension in water at 77 DEG C. for 5 minutes and then annealed. The drawing step may be done at 80-130 DEG C., and may be conducted in one or more steps in air or a bath of glycerol or water.

Patent GB-1083458-A (GB)
Title: Improvements in or relating to apparatus for conveying mineral in mines
Inventor: LOW ALEXANDER CHARLES
IPC: E21F13/02
Filed: 1963-10-19
Abstract: 1,083,458. Conveyers for mines; hoppers; bunkers. MAVOR & COULSON Ltd. Jan. 1, 1965 [Oct. 19, 1963], No. 41365/63; Headings B8A, B8E and B8S. Conveying apparatus particularly suitable for use in a coal mine includes a hopper 3 into which mineral is discharged if a stoppage of a conveyer 2 occurs. A first conveyer 1 normally discharges into a shoot 4 of the hopper 3 and mineral passes on to the conveyer 2. The hopper also includes a series of doors 17 of inverted V-shape which are pivotal about an axis 18 at the apex of each V. Counterweights 19 ensure that the doors 17 normally close the bottom of the hopper. When the conveyer 2 stops the shoot becomes blocked and a pivotally suspended door 16, due to the mineral, swings into the position shown at 16A and closes an aperture in the bottom of the hopper 3. When the shoot 4 is full mineral passes over the shoot into the hopper and fills the pockets formed by the doors 17. If the hopper fills completely the conveyer 1 is automatically stopped. Assuming the conveyer 2 (which conveys at a faster rate than the conveyer 1) has just been restarted, the shoot 4 clears, the door 16 swings open under the weight of mineral in the first pocket of the hopper 3 and the mineral is moved away by the conveyer 2. When the first pocket is sufficiently cleared of mineral, mineral in the next pocket falls due to the weight of the mineral swinging the door open to the position shown at 17C, 17D. The process is repeated for the remaining pockets until the hopper 3 is empty.

Patent GB-902024-A (GB)
Title: Improvements in or relating to memory systems
IPC: H01L29/00
Filed: 1959-12-08
Abstract: 902,024. Semi-conductor data-storage devices. GENERAL MILLS Inc. Dec. 8, 1959 [Dec. 8, 1958], No. 41735/59. Class 106 (1). [Also in Groups XXXVI, XXXIX and XL (c)] A data storage system includes a semiconductive element having a grain boundary, means for applying a potential to the element to charge the grain boundary so as to represent information to be stored, and means for applying an interrogating signal to the element to determine the state of the boundary charge and thus provide an indication of the stored information. A matrix of the semi-conductive elements is formed by a slab of N-type germanium 42, Fig. 6, having orthogonal grooves 46, 48 on opposite faces and which extend deeper than the grain boundary 44. Information in the form of a pulse which may have one of several possible amplitudes or merely represent a binary " 1 " is supplied from generator 34 to an element which is selected by means of switches 70, 72. In a subsequent read-out operation, the amplitude of the current pulses derived from the elements depends on the data stored, e.g. a larger pulse is obtained from elements which were initially uncharged to represent " 0 " than from those which were charged to represent " 1," all elements being left in a charged condition at the end of the read-out operation. The elements may be discharged by illuminating them with light from a lamp 74. Alternatively, each element may be provided with a hole-injecting contact connected to a separate read-out generator, each element being left uncharged at the end of the read-out. Non-destructive read-out may be obtained by connecting each element as part of a resonant circuit and employing an R.F. read-out signal to indicate the capacitance of the elements, and hence their charge. Fig. 9 shows an embodiment in which all the elements of matrix 42 are initially charged, and information is stored in selected elements by deflecting the electron beam of cathode-ray tube 100 so that light falls on and discharges the selected elements. The magnitude of the current pulse obtained during read-out by generator 98 is indicative of the information stored, each element being left in the charged state, ready to receive further information.

Title: Improvements in cracking liquid hydrocarbons
Inventor: KNOBLOCH WALTER
IPC: C10G9/00
Filed: 1960-12-06
Abstract: <PICT:0911114/IV (b)/1> The production of olefins or producer gas is effected by vaporizing a vaporizable liquid hydrocarbon mixing it with oxygen or air and steam or carbon dioxide, and introducing it at atmospheric or increased pressure through a burner into a reaction chamber and simultaneously introducing a non-vaporizable liquid hydrocarbon through an atomizing jet in the same burner into the mixture of vaporized hydrocarbon and gases.  Vaporizable hydrocarbons are hydrocarbons which can be vaporized without leaving a residue, e.g. light gasoline, liquefied gases and petroleum distillates; non-vaporizable hydrocarbons are those which cannot be vaporized without leaving a residue, e.g. crude oils, residue oils and oils containing compounds forming non-volatile resins.  The vaporizable and non-vaporizable liquids may be obtained from a single feed by passing into a vaporizer, the nonvaporizable portion being recovered from the sump. Suitable conditions are 600 DEG -2,000 DEG C. and up to 30 atmospheres. In the drawing, vaporizable hydrocarbon enters through vaporizer 1, and gases by line 3 and after mixing flow through the annular space 4 of the burner 2.  Liquid hydrocarbon is preheated before spraying through jet 7 which is drawn back to prevent wetting of the reaction chamber walls.  The whole mixture is ignited.  The reaction chamber may be empty or filled with coke or other inert solid or catalyst.
