Abstract: 1306180 Armour piercing incendiary projectiles and fuzes therefor K DIEHL 30 June 1971 [9 July 1970] 30604/71 Heading F3A A projectile which can be used against both armoured and structurally weak targets comprises a ballistic cap 4, Fig. 1, containing an incendiary charge 8, an armour-piercing body 1 containing an explosive incendiary charge 9, and a base fuze 6, 7 which detonates the charge 9 and causes the body to 1 burst behind the walls of the target thus scattering fragments and ignited incendiary composition in the target. A groove 3 provides a predetermined breaking line. The charge 8 ignites spontaneously at impact. The fuze 6, 7 comprises an inertia member 15, Fig. 2, integrally formed with a striker 18, a centrifugal spiral safety band 31 preventing movement of the striker against a detonator 32, and a spring loaded abutment member 21 which is locked in position by a centrifugal member 26 that is released only when the rotational speed of the projectile drops below a predtermined value. Upon firing the projectile, the band 31 expands and the striker 18 is thrown. against the detonator when a hand target is encountered. With a soft target, or in the event of a miss, the centrifugal member 26 unlocks the abutment member 21 when the speed of rotation falls sufficiently, and the spring 22 causes the abutment member to drive the striker into the detonator.

Abstract: 966,445. Feedwater heating systems. C. A. PARSONS CO. Ltd. July 31, 1963 [Aug. 13, 1962], No. 30973/62. Heading F4A. In a feedwater heating system for a steam turbine plant the feedwater is passed through successive direct contact heaters which are arranged in groups of two or more, the heaters of a group being at different levels so that the feedwater flows from the highest through successively lower heaters in the group until it reaches the lowest under gravity, the water being pumped from one group to the 'next. In the form shown, the direct contact heaters 1 . . . 7 are arranged, except for the last heater 7, in groups of two. In each group the height of the first heater 1, 3 or 5, above the second 2, 4 or 6, is sufficient to allow feedwater to flow by gravity against the pressure existing in the second heater. Pumps 8, 9 lift the water from the lower heaters 2, 4 respectively to the higher heaters 3, 5 of the next group, whilst a pump 10 lifts the water from the heater 6 to the heater 7 whence it enters a tank 11, a pump 12 drawing the water from the tank and discharging it through a tubular heater 13 to the boiler feed pump 14. Steam tapping lines 15 ... 20 convey steam from the main turbine to the heaters, the line 20 supplying the heater 13 and also supplying steam to the turbine 21 of the pump 14. Steam tapping lines from the turbine 21 convey the steam to the heaters 7, 6 and additional steam to the heater 4.

Abstract: 320,540. O'Dell, A. E., (Siemens-Reiniger- Veifa Ges. f³r Medizinische Technik.). Oct. 29, 1928. Supplying and controlling consuming devices; systems depending on static transformers; charging and discharging condensers.-In making X- ray photographs with a short exposure, condensers are discharged through an incandescent cathode tube. the primary circuit of the supply transformer being broken at the beginning of the discharge by an overload release device. In the Figure, g denotes an overload release device included in the primary circuit a, which supplies energy to the condensers b and c through the high tension transformer secondary d and rectifier tubes e and f. The X-ray tube h is connected to the condensers bv leads 2 and 3. When the cathode is heated by direct current, the tube current may enter the cathode in the opposite direction to the heating current or, in the case of relatively low power apparatus, in the same direction. When the cathode is heated by alternating current, the lead 3 is joined to the mid point of high resistances W1, W2, bridging the leads conveying the heating current. To control the exposure a magnetically actuated high tension switch or a valve tube i, which can be made to act as a switch by deflection of the electron stream or by using a grid, is connected in series with the X-ray tube. The heating current is interrupted upon completion of the exposure by an overload release device k, delay action relay or fusible cut-out.
