Abstract: 1,177,231. Liquefied gas containers. G. J. H. TREPAUD. 27 Jan., 1967 [28 Jan., 1966; 10 June, 1966; 12 Jan., 1967], No. 4071/67. Heading F4P. In the event of an undue external temperature rise, liquefied gas e.g. butane stored under pressure at or below a level 16 in an inner tank 1, Fig. 1, is caused to rise up the annular space 7 between tank 1 and a surrounding tank 5 thereby cooling the latter and the so-vaporized butane is freed of entrained liquid particles by passage through a conventional separator 13, 14, 15 and is then passed through a duct 12 containing a bursting disc 23 to an open-air burner system (not shown). The bottom portions of tanks 1, 5 are connected by ducts 8, 8<SP>1</SP> having normally closed valves 10, 10<SP>1</SP> which open at a predetermined temperature to allow access of liquid butane to annular space 7 and also through apertures 20, 21 in hollow tank-supporting legs 2. Liquid particles separated by an annular baffle 14 and a filter mesh 15 are returned through a funnel 13 and a vertical duct 3 to the lower portion of the outer tank 5. The latter is coated externally by an asbestos layer 6. In a modification the upper and lower portions of inner tank 1, Fig. 4, are open to the outer tank 5 and liquid forced up space 7 is vaporized,. freed from liquids by baffles 45, 13, 14 and is relieved through valves 70, 70<SP>1</SP> to the open-air burner. In a further modification, when the upper and lower portions of the inner tank 1, Fig. 5,. are open to the tank 5, the inner tank is formed of separate segments 1a, 1b, Fig. 7, secured along their edges to spaced rectangular sectional ducts 46, 46<SP>1</SP> which extend in vertical meridian planes and are welded to the outer tank 5. The duets are open at their lower ends 47, 47<SP>1</SP> and are connected at their upper ends 48, 48<SP>1</SP> to atmosphere through a fuzible disc 50, Fig. 6 and a next duct 49 and also to the inner tank through a non-return valve 52.

Title: Paired cylinder two stage combustion IC engine - has valve connecting cylinders for second stage lean fuel, rich oxygen combustion
IPC: F02B75/02
Filed: 1976-10-14
Abstract: An internal combustion engine has one or more compounded pairs of undulating volumes, such as produced by a piston reciprocating within a cylinder which share periodically common combustion and which are provided with combustible fuel mixtures prepared externally. The fuel-air mixture, when involving a petroleum type fuel, is burned internally in two stages, the first burn at elevated temperatures is a fuel-rich, oxygen-lean mixture to minimize the nitrous oxides produced, and the second burn at lower temperatures is a fuel-lean, oxygen-rich mixture to substantially complete combustion of unburned hydrocarbons and oxidize carbon monoxide prior to being exhausted to the atmosphere. Paired cylinders communicate to form a common combustion chamber to effect the second stage burn and extended power expansion by differential displacement. Both cylinders have inlet valves, only the second stage having an exhaust, a movable valve allowing communication between the cylinders.

Title: Automatic synchronisation system for sampling oscilloscopes - takes signal from second output of splitter in phase with input to feedback circuit comprising filter and VCO
IPC: G01R13/34
Filed: 1977-05-06
Abstract: The automatically-synchronized system for sampling oscilloscopes operates with a double sampling sequence and requires no wide-band amplifier and divider. The h.f. signal being measured is fed directly to the input of the sampling circuit. A splitter has one output connected to the oscilloscope and produces a l.f. representation of the input signal. A signal in phase with the input is taken from the second output to a feedback circuit comprising a filter and v.c.o. The oscillator drives the sampling circuit in phase with the input. In the second sampling phase, the oscillator triggers sweep and step generators whose outputs are fed to a comparator. This supplies a phase-shifted sampling. The double operating mode provides time-multiplex operation of the sampling circuit and the amplifier and pulse-shaper circuit.

Title: Induction spool for casting round ingots of ferrous metals and alloys - using inset pieces of high resistivity at current connections to correct electromagnetic field within spool
IPC: B22D11/01
Filed: 1977-12-12
Abstract: Round metal ingots are (semi-) continuously cast by means of an induction spool which is circular in form, constructed of a hollow box section material and connected at two points to current feed and discharge cables, the connections being divided by an insulating shield set radially into the spool. On each side of the insulating shield, there are inset pieces of a material with a specific resistivity pref. of the order of 40 to 60 times greater than that of the spool material itself. The function of the inset pieces which are box shaped, pref. three times as long as the width of the spool section with their inner walls lying against the inner wall of the spool, is to concentrate the induction current along the inner face of the spool at the cable connection points thereby ensuring that the induced mangetic field within the spool is uniform. The incorporation of the inset pieces ensures that the cross-section of the cast ingot is uniformly round and undisturbed at the face opposite to the current connections on the spool.
