Title: Explosive charges having ignition characteristics
IPC: F42B3/00
Filed: 1971-07-26
Abstract: 1361983 Explosive charges; detonators DYNAMIT NOBEL AG 26 July 1971 [24 July 1970 6 Aug 1970] 35043/71 Heading F3A An explosive charge having an improved brisance comprises a solid body of explosive material with at least one passage extending therethrough for the throughflow of combustion gases when detonated at one position, which body is adapted to produce, as a result of said throughflow, a shock wave or detonation front which emanates from each of a plurality of positions in the passage and travels towards a position on the periphery of the body which it reaches before a detonation front travelling from said one position in the direction of the passage, the velocity of the detonation front being less than the velocity of the combustion gases. The detonation fronts or shock waves emanating from each of the plurality of positions are created respectively, by blocking the passage 3, Fig. 5, in the charge 1 with plugs 4 of inert or explosive material, or by leading the combustion gases directly to the periphery of the charge through lined, or unlined, cavities 1, 3, Fig. 8. The charges are ignitable by detonators 5 and may be surrounded by casings 12 which are burst into splinters of a length determined by said plurality of positions. The charge can be used as a detonator if inserted in a bore in a charge of larger diameter. In another embodiment (Fig. 3, not shown) the charge is in the form of concentric charges with an annular passage therebetween or is in the form of a sphere (not shown) with a plurality of radial passages emanating from a central ignition point.

A water-tube steam boiler heated by exhaust gases from an internal-combustion engine comprises upper and lower tube plates 6, 8 to which are respectively bolted covers 4, 7 enclosing respectively a steam collector chamber 1 and a  water receiver chamber 2, the chambers being connected externally by a valved downcomer pipe 17 and by a bank of vertical water tubes 3 which extend between the tube plates. The tube bank is encased by insulated plates 11-14, plate 13 being formed with a central opening through the upper half of which the exhaust gases enter the boiler at 20, the gases flowing horizontally through the tube bank above a guide plate 15 and returning under the plate to discharge at 22 through the lower half of the opening. A rotatable damper 18, the setting  of which may be regulated automatically by means responsive to variations in steam output or pressure, is disposed between the gas inlet and outlet ports to control the volume of gas entering the boiler. Thus, for example, if the boiler pressure rises the damper is turned towards its closed position to decrease the flow of gas into the boiler and at the same time provide a by-pass for the surplus gas, as indicated at 19. Chambers 1, 2 are provided with anti-surge baffles 9, 10 when the boiler is to be fitted to a vehicle. A tubular heat exchanger 16 for preheating the feed water by means of the engine cooling water is disposed in the lower part of chamber 2.

Abstract: 1,150,138. Valves. THERMAL HYDRAULICS CORP. 7 Aug., 1967, No. 36181/67. Heading F2V. [Also in Division G1] A temperature responsive actuator for a valve 45 comprises a casing 10 containing a chamber 11 filled with thermally expansible wax adapted to be heated by a heating element 12 through which a constant electrical current is passed, the wax moving a piston shaft 16, 22 to actuate the valve, the casing 10 being surrounded by a housing 30 to provide an annular space 34 through which a cooling fluid is passed, this fluid ensuring that overheating of the actuator does not occur. In the arrangement shown, the cooling fluid is the same as the fluid controlled by the valve 45, the effect of the fluid flow from the valve inlet 39 to the outlet 41 causing a suction effect in a passageway 36 thus drawing a by-pass cooling flow through the space 34. The valve 45 is provided with a seat 44 and a spring 46 urges the valve towards its closed position. The shaft of the actuator acts through a bearing 50 to open the valve, its movement being guided by a stem 51 sliding in a sleeve 52. The end of the sleeve 52 functions as a limit stop for the valve. The sleeve 52 is formed integral with a cap 48 which is also provided with an arcuate vane 54 for controlling the velocity of fluid flowing through the valve. The position of the vane can be adjusted by turning the cap in its screw-threaded mounting and set by tightening a set-screw 55. Provision for manual operation of the valve 45 is accommodated by mounting the casing 10 in a ring 24 which may be reciprocated to open and close the valve by manual rotation of a screw-threaded pusher member 31. Electrical wires 14 connected to the element 12 pass through a central bore in the member 31. If desired, a separate cooling fluid may be provided for the actuator, the valve being used to control flow of another fluid, e.g. steam, in a separate conduit.

[Class 78 (i)] [Also in Group I] A bread-slicing machine is provided with a pair of parallel conveyers, each of which has flights which extend towards one another and are arranged to engage a loaf and feed it to the slicing-knives. The flights may be arranged horizontally to engage the opposite ends of the loaf, but as shown, a conveyer 3 is arranged above a conveyer 1, the flights 4 being pivoted at 6 so that backward extensions 7, having bearing members 9, engage a track 10 which holds the flights in vertical positions during the loaf-pushing movement. The track 10 releases the extensions 7 just as a preceding loaf comes into contact with the knives, the flights 4 thus being allowed to pivot idly as they are withdrawn from the loaves. The loaves are moved through the knives 11 by the positive feed given to the following loaves. The conveyer 3 is driven from the conveyer 1 by chain gearing 12, 13, the conveyer 1 having flights 2 pivoted and controlled by a track as described in relation to the flights 4. The flights 4 may be arranged to lag behind the flights 2 to compensate for irregularities in the loaves. The conveyer 3 is mounted in a structure 15 which is adjustable vertically in virtue of the slots 16, so that the flights 4 may move in a path to suit the height of the loaves. The loaves are supported, adjacent to the knives, by plates 18 having serrated forward ends, the plates being adjustable about horizontal axes 19, 20. Side guides 21 for the loaves are provided.
