Title: Oscillating-water-column wave-energy device having a helical column
Inventor: DUCKERS LESLIE JOHN
IPC: F03B13/14
Filed: 2008-04-21
Abstract: An oscillating-water-column (OWC) device for capturing energy from waves comprises a helical column B, C within which water can resonate. The helical column is formed by a spiral C running along the length of a column B. By having a helical column as opposed to a vertical one, the height of the wave energy device can be reduced while retaining the same column length required for resonance. The reduction in height of the column enables the device to be installed closer to shore, and operate closer to the surface of the sea. The device may comprise a central spine D, while two or three spirals C may run (collectively) clockwise or anticlockwise along the tube / column B to thereby form helical columns. A floatation buoy (A) is preferably attached to the OWC device. Preferably the oscillating water column drives an air turbine, which in turn drives a generator to produce electricity.

Abstract: 787,635. Fuel injection systems; regulating. TEXACO DEVELOPMENT CORPORATION. April 7, 1954 [April 16, 1953], No. 10189/54. Classes 7(3) and 7(6) [Also in Group XXVIII] 'In a fuel-injection type engine having means causing the air to swish in the cylinder, the fuel injection pump is provided with control means comprising a piston 80 adjusted by a cam 82 in response to engine operating conditions for varying the initial volume of the fuel injection system, i.e. the volume fuel between the pump plunger and injection orifice at the start of the pumping stroke, thereby varying the duration of injection. As applied to an engine in which liquid fuel is injected from a nozzle 32. Fig. 2, into the rotating air in the cylinder, in such manner that the fuel-air mixture progressively formed is swept towards a flame front established by a spark plug 44, where combustion takes place, the duration of injection is varied in accordance with engine speed and hence in accordance with the rate of swirl of the air. The duration of injection is controlled by varying the initial volume of the compression space of the fuel injection pump by means of the piston 80, Fig. 3, whose position is adjusted by cam 82 in accordance with engine speed. The duration of injection may also be varied by a nozzle 110. Fig. 4, used in conjunction with the pump of Fig. 3. In Fig. 4 the load of the valve spring of the fuel injection valve is varied with varying engine speed by means of a plunger 140 carrying the valve spring abutment and actuated by the average pressure. in the fuel delivery pipe 35 transmitted through a narrow bore pipe 144 to a chamber 142 The average pressure in the pipe 35 varies with varying engine speed and the resulting variation in the load of the valve loading spring varies the valve ' opening pressure and hence the duration of injection. In a modification, Fig. 5, the pressure in the pipe 144 acts upon a plunger 154 which adjusts a screwed stop 150 limiting the lift of the injection valve 152. The plunger 154 carries a pin 160 engaging helical slots in the end of the stop 150 whereby axial movement of the plunger causes rotation of the stop 150. In supercharged engines the duration of fuel injection is varied in accordance with the supercharging pressure in addition to engine speed. Specification 596,846 is referred to.

Title: Process of preparing ª-ionylidene acetaldehyde
IPC: C07C47/38
Filed: 1964-03-11
Abstract: The invention comprises 5-(21,61,61-trimethyl cyclohexene - 11 - y1) - 3 - methyl - 3 - hydroxy - 1,1 - dialkoxy - 4 - pentynes (C15 - acetylenic hydroxy acetals) and corresponding 4-pentenes (C15 ethylenic hydroxy-acetals); and the preparation of b -ionylidene-acetaldehyde by converting 1 - ethynyl - 2,6,6 - trimethyl - cyclohexene into the corresponding Grignard magnesium derivative, condensing the latter with a b -ketobutyraldehyde acetal thereby obtaining a C15 acetylenic hydroxy acetal, partially hydrogenating this to the corresponding C15 ethylenic hydroxy acetal which, by hydrolysis accompanied by dehydration is converted into b -ionvlidene acetaldehyde.  The first step is effected by reacting 1-ethynyl-2,6,6-trimethylcyclohexene with RMgX, where R is C1- 6 alkyl and X is bromine or chlorine, in an ether.  To the Grignard is added an acetal CH3COCH2CH(OR)2, where R is C1- 6 alkyl, with moderate heating if necessary, and the C15 acetylenic hydroxy acetal is purified by molecular distillation. The partial hydrogenation may be effected by hydrogenation with a deactivated catalyst such as Raney nickel deactivated with zinc acetate-piperidine or piperidine alone, or palladium deactivated by quinoline or pyridine. Alternatively the hydrogenation is effected by an alkali metal aluminium hydride.  The hydrolysis of C15 ethylenic hydroxy acetal is carried out by a hydrohalic acid in acetone, methylethylketone, dimethylformamide or acetonitrile.

Title: Improvements in fluidized bed roasting of metal sulfide concentrates
IPC: C22B1/10
Filed: 1955-04-12
Abstract: <PICT:0769267/III/1> <PICT:0769267/III/2> Sulphide ores are fed to a fluidized bed roasting process in the form of agglomerate particles suitable for fluidized roasting, e.g. so as to pass through a 4 mesh screen and preferably through a 200 mesh screen, characterized in that the ore concentrate is sprayed as an aqueous slurry through the freeboard space above the level of the bed and the size of the particles in the slurry, the air quantity used for spraying the amount of water in the slurry and the dimensions of the furnace are controlled so that the particles enter the bed in a substantially dry condition.  Ores treated include nickeliferrous pyrrhotite, cupriferous sulphides including sulphide-oxide mixtures, auriferous iron sulphides including those containing arsenic, iron sulphide including those containing lead, zinc and copper.  Salts such as sodium sulphate are introduced into the slurry to aid the roasting. Argillaceous substance such as bentonite may be added to effect some bonding of the ore slurry during spraying.  A valved slurry feed line 10 with constant head tank 12 discharges slurry through line 20 to slurry feed line 24 by means of pump 22 and extends by coupling 25 through a removable cover 30 on a hood 32 mounted centrally around a manhole 33 on top of roaster 34.  Air to help in spraying may be fed in at 26.  The slurry is sprayed through the freeboard space and reaches the level of the bed at 118 as suitable dry particles for fluidized roasting.  The temperature of the bed and freeboard space may be controlled by spraying water through pipes 202 and 204 as shown. The ore fines may be recycled via pipe 124, cyclones 126 and 128 and fed back to the bed via feeder 140.  Burners 180 and 182 may be used to bring the bed to the initial temperature necessary for roasting.  Ore is discharged by overflow from pipe 116.  The air discharge nozzles 54 for the roasting, illustrated in Fig. 5, are standard pipe couplings or fittings 144 mounted on the upper ends of pipe nipples 146 and secured to plates 48, 50 and 52 (see Fig. 1) and through holes 148.

This prevents clogging of the jets with fines and presents a dead overall layer 160 which insulates plates such as 50.
Patent GB-105528-A (GB)
IPC: E21B1/30
Abstract: 105,528. Fletcher, J. April 17, 1916. Percussive drills; percussive channelling drills. -In a fluid-operated percussive rock drill or coalcutter, a by-pass 29 manually controlled by a valve 31, is provided between the front port 24 and the cylinder; if the by-pass is open, cushioning due to incoming fluid is relieved when the piston passes the by-pass in its forward stroke. Further by-passes 33 - - 37 are provided in the cylinder and are controlled by a manually-operated tube valve fitting in an aperture 32 ; by manipulating this valve, the port 50, communicating with the ports 52, 53 leading to the ends of the main valve 70, is put in communication either with the by-pass 34 only, or with pairs of bypasses 33, 35, or 34, 35, or 36, 37, whereby the length of stroke of the piston and its path of reciprocation in the cylinder are varied. The fluid inlet in the valve chamber 26 communicates with annular passages 62, 63. With the main valve 70 in the position shown, fluid passes from the passage 62 through a port 22 to move the drill piston forward, and from the passage 63 through ports 80 in the valve to a recess 68<x> to lock the valve; exhaust passes through passages 24, 64, 61. When the piston passes any by-pass 33 - - 37 that is open, fluid from the cylinder passes to the port 50 and thence through ports 52, 72 to act on the valve piston 73, and also through ports 79 to act on the valve plunger 69; this fluid overcomes the pressure in the recess 68<x>, and the valve moves over. The return stroke is similarly effected.
