Title: Improvements in or relating to the manufacture and production of concentrated nitricacid
IPC: C01B21/44
Filed: 1930-12-22
Abstract: Nitric acid is concentrated by exposing a downflowing mixture of weak acid and a dehydrating agent, such as sulphuric acid, in a fractionating column or tower to a counter-current of weak nitric acid vapour resulting from the distillation of the effluent collected at the base of the column, which is heated in such a manner that the vapours generated pass a counter-current to the effluent while it is undergoing distillation.  The heating of the effluent may be carried out in any suitable manner, avoiding the direct introduction of heated gases or steam.

Abstract: 1,044,667. Semi-conductor switching circuits. GENERAL ELECTRIC CO. Oct. 3, 1963 [Oct. 4, 1962], No. 38979/63. Heading H3T. [Also in Division H2] An overload protective arrangement for a plurality of loads, e.g. inverters 11a . . . 11d comprises a resistor 12a ... 12d in series with each load and a gating circuit 14a ... 14d connected across each resistor and including a tunnel diode 21 and a pulse transformer 26. These pulse transformers are connected through coupling diodes 29a . . . 29d to the gating electrode of a silicon-controlled rectifier 31 which is connected in series with the primary winding of a pulse transformer 33. When an overload occurs, the increased voltags drop across a resistor 12 causes a tunnel diode 21 to change its state and the resulting pulse from transformer 26 renders the controlled rectifier 31 conducting. The resulting pulse produced in each of a plurality of secondary windings 34a of the transformer 33 causes a silicon-controlled rectifier 37 in each of the circuit units 15a . . . 15h to conduct and connect a low value resistor 38 across the power supply to the inverters. Thus the units 15a . . . 15h effectively short-circuit the supply and cause the opening of a circuitbreaker or the blowing of a fuse 16.

Abstract: 957,596. Pneumatic jacks. COMPAGNIE PARISIENNE D'OUTILLAGE A AIR COMPRIME. Oct. 16, 1962 [Oct. 16, 1961], No. 39199/62. Heading F1P. [Also in Division G3] A pneumatic jack having maximum power and speed at the start of both the forward and return strokes has the side 5 of the piston 3, Fig. 1, connected to a distributer 6 which is adapted to communicate with either a pressure source 7 or atmosphere 8 and the other side 10 connected to a reservoir 11, an escape path 13 being provided between the side 5 and the composite volume formed by the side 10 and reservoir. As shown in Fig. 2, the reservoir 11 is incorporated in the piston rod 4 and is in communication with the side 10 through an orifice 20. The rate of flow along the escape path is controlled by means of a throttle formed by a helical groove on a plunger 29, the plunger being adjustable by screw means along a stepped axial bore in the piston so as to vary the effective length of groove. Damping at the end of each stroke is effected by means of ducts 22, 23 and 25, 26 provided with throttling adjustments. To operate the jack, the side 5 is connected with the air supply 7 and as the piston moves along its stroke, the power of the jack decreases owing to compression of the volume of air at the side 10 and in the reservoir, the throttling device in the escape path 13 operating so that the pressures on each side of the piston become balanced on completion of the stroke. The return stroke is effected by connecting the side 5 with atmosphere and as the piston moves along its stroke, the power of the jack decreases at a rate depending on the rate of escape through the path 13 and the rate of exhaust through adjustable reducing means 9; at the end of the return stroke the pressures on each side of the piston are balanced. A duct 35 is provided to expand piston packings 33, 33a. In another embodiment, Fig. 4, the reservoir is disposed externally and adapted to receive the escape path 44, 46 controlled by reducing means 45; instead of single reducing means 45 to serve both forward and return strokes, additional reducing means 45a together with non-return valves 47, 47a may be employed.

Title: Improvements in and relating to a Mine-Sweeping Alarm Device for Marine Mines
IPC: B63G7/00
Filed: 1961-11-06
Abstract: 1,193,010. Marine mines. GERMANY, FEDERAL MINISTER OF DEFENCE. 6 Nov., 1961 [18 Nov., 1960], No. 39717/61. Heading B7A. A mine-sweeping alarm device comprises transmitting means and also means to release the device from a mine, whereby when a minesweeping operation or other disturbance occurs, the device is released from the mine and rises to the surface of the water for transmitting a signal. The object of the invention is to provide a device which will give warning when a ship passes over a mine or when a sweep occurs. In Fig. 1 (a) the mine 1, with an alarm device 2 fixed to it, is laid on the sea-bed. The device 2 is connected to the mine 1 by a soluble coupling which includes lumps of a watersoluble salt, and in (c) the coupling is shown to have been dissolved and the device moored by a cable 3 which includes an explodable coupling 4. An antenna 5 is shown. In (d) the ship causes the coupling 4 to explode and part the cable 3, which allows the device to reach the surface and transmit a radio alarm signal. In (f) the device destroys itself by explosion and sinks. The mine may be fitted with a slowacting relay so that the release of the device may be delayed. The sinking fuse may be triggered by clockwork mechanism set in motion on explosion of the coupling 4, or by an hydraulic pressure switch. The battery for the radio transmitter can be switched on by the same means. The device may be used to signal the passage of a particular type of ship, e.g. submarine, or the passage of a convoy or warship squadron. In another embodiment, Fig. 2 (not shown), both the mine and device are moored. The device may be arranged to detonate the mine to which it is connected when a ship comes within effective range of the mine.
