A device for use in explosive forming operations comprises means for supporting one side of the material to be formed and a member having passing therethrough one or more apertures opening on to the opposite side of the material and adapted to direct and concentrate a shook wave by multiple reflections upon said material. The apparatus comprises a foundatoin 1 of e.g. cement, in which is located a cylindrical female die member 3 of e.g. steel having female die cavities 4 of a circular, rectangular or triangular cross-section, a cylindrical workpiece 5 positioned therein in which is located, in abutting relationship, a member 6 having a plurality of shock channels 7 complementary in position and shape to the die cavities 4 and in which is positioned an explosive charge 8 surrounded by a liquid, solid or gaseous force transmitting media of e.g. soft plastics, sand, powder, air or water. The explosive charge e.g. dynamite, P.E.T.N. T.N.T., or R.D.X. of a spherical, rectangular or cylindrical shape is fired via a detonator to punch holes 14 through the walls of the workpiece 5. The shock channels 7 are preferably tapered having an angle α between 0 degrees to 45 degrees preferably between 0 degrees to 30 degrees, the cross sectional size and shape of the channel thereof adjacent the workpiece being complementary to that of the die cavity 4. To carry out seam welding or shearing operations a shock channel 7 of a long trough-like configuration running the full length of the workpiece in conjunction with a slender charge of a similar length may be used. To perform a single drawing operation the die cavity which may be hemispherical cup shaped, is preferably closed at one end and evacuated. The materials of the workpiece may be Rene 41, PH-17 Molybdenum steel, titanium or aluminium.

Title: Improvements in and relating to tubular heat exchangers
IPC: F22B1/18
Filed: 1965-05-19
Abstract: 1,109,669. Tubular heat exchangers; steam generators. WAAGNER-BIRO A.G. 19 May, 1965 [20 May, 1964], No. 21371/65. Headings F4A and F4S. A heat exchanger comprises helically coiled tubes defining a plurality of telescoped coaxial cylinders each containing one or more tube coils and the tube lengths, which include pipes connecting the tube coils to headers, increase in length with each increase in cylinder diameter, the increase in length diminishing from cylinder to cylinder. In one form (Figs. 1-3) the axial tube spacing is constant and the ratio of number of tubes to cylinder diameter decreases with increasing cylinder diameter. Alternatively the ratio of number of tubes to cylinder diameter may remain constant, the axial tube spacing from cylinder to cylinder decreasing with increasing cylinder diameter. In another form described (Fig. 5) the axial spacing (27) increases with increasing cylinder diameter, the transverse spacing (28) between adjacent cylinders remaining substantially constant. Further arrangements comprise two concentric groups of cylinders one group having smaller diameter tubes than the other (Fig. 7). Alternatively (Fig. 8) these cylinders of smaller and larger tubes may be arranged alternately, and may be superheater and reheater tubes. The drawing shows steam generating plant in which a flow of hot gas (which may be assisted by a fan at the point 57) flows over the tube cylinders. Feed water enters via header 58 and passes through preheater, evaporator and superheater sections 60a, 60b and 60c respectively from which steam flows via header 62 and temperature regulator 63 (e.g. an injection cooler) to a header 64 which conducts the steam to a final superheater 66. Interleaved with the cylinders of tubes 66 are other tube cylinders 73 in which expanded steam from a turbine (not shown) is reheated before passing out at 72 to the low pressure part of the turbine. 75 is a tube supporting structure (not described in detail) from which the tubes are suspended. 74 is a baffle to prevent by-passing of the tubes by the heating gas.

Abstract: 1,089,374. Cartridge-actuated tools. BIRMINGHAM SMALL ARMS CO. Ltd. May 24, 1965 [May 23, 1964], No. 21383/64. Heading B4C. A cartridge-actuated tool for driving nails, studs or the like comprises a driving piston 3 and a gas-bleeding control screw 8 whereby a proportion of the gas can be diverted to atmosphere or to other parts of the tool thereby varying the pressure applied to the piston. The cartridge chamber 4 is connected by passages 5, 6 to the cylinder space above the piston and by passages 5, 11 to atmosphere or to the under. side of the piston. When full pressure is required to act on the piston the screw is rotated to close the passage 5 and when less pressure is required the screw is released so that some of the gas flows to the underside of the piston. Graduations may be provided in order to indicate the length of nail which can be used with a particular setting of the screw.

Title: Process for preserving hops
IPC: C12C3/04
Filed: 1930-07-18
Abstract: Hops are preserved in storage chambers the moisture content of the air in which is made such that drying of the hops does not take place.  The content is preferably such that even with the rise in temperature which takes place in the chamber it does not fall below about saturation point, but does not cause wetting of the hops.  The air may be circulated from the chamber to a cooler where the moisture is removed, and water in a finely divided form is then added to the cooled air, for example by means of a Schlick centrifugal atomizer, before its return to the chamber.  The water, which may contain a disinfectant or other suitable addition, frees the air from dust, bacteria, odorous substances, &c.  Cooling may be effected in separate chambers having cooling coils or in the spray chamber by cooling the spray water to which substances lowering its freezing-point may be added.  Fresh air may be added to the circulating air.ALSO:Hops are preserved in storage chambers the moisture content of the air in which is made such that drying of the hops does not take place.
