Title: Reciprocating jet mixer - having perforated discs mounted on reciprocating shaft in cylinder
Inventor: BRAUER HEINZ PROF DR ING
IPC: B01F11/00
Filed: 1975-06-06
Abstract: Mixer consists of a cylindrical mixing vessel in which is located a shaft with circular mixing elements at intervals along it. The shaft is on the axis of the cylinder and can move axially with a reciprocating motion. Guide elements can be attached to the shaft and/or the mixing elements. The elements divide the mixer into stages and their dia. is only slightly less than that of the cylinder. The stroke of the shaft is approx. equal to the element spacing. The stroke in each direction can be of different durations. The disc movements create jets in the mixer which project into adjoining causing a mixing of fluid present in the mixer. Used for mixing and homogenising phase mixtures such as two or more liquids; liquids and gases, the liquid being the continuous phase; liquids and particulate solids; liquids and bubbles; or solid particles. This can be done batchwise or continuously. Can be for heat or mass transfer operations. Dynamic mixers generally employ rotating elements in which the bulk of the energy is imparted to the tangential component which is ineffective for mixing purposes. The system described uses all the energy for the mixing.

Title: Air conditioning heat exchanger with plates - having cross flow pipes with slot type projections punched into plate
Inventor: KOBAYASHI NOBUYUKI
IPC: F28F1/32
Filed: 1975-06-18
Abstract: The heat exchanger consists of a bundle of plates with several tubes of about 10mm dia. running through them joined by U bends. The plates have a series of short and long slot like projections cut or pressed into them formed into several series. Each series has two rows of short slots flanked on either side by a row of long slots. In each series are the holes for the tubes and these have projecting spacer ties. The slot rows interchange with the row of holes. The slots and the space between them are both 2.0 to 2.2 mm wide. The ht of the projection over the slots is equal to half the ht of the projecting spacer tie, which is 1.8mm at most. The tubes are arranged on a triangular pitch with centres on an equilateral triangle of 23.5 to 25 mm. For use in air conditioning equipment. This type of exchanger is common for heating air streams but heat transfer is relatively poor between the plates and the air. The system described improves this and therefore gives a more compact exchanger.

Title: Extraction of viscous oils from undergound formations - using low-temp oxidn by oxygen - steam mixts
Inventor: REDFORD DAVID ARTHUR
IPC: E21B43/243
Filed: 1975-06-19
Abstract: Recovery of hydrocarbons from underground formations provided with at least one injection hole and at least one prodn. hole, with a connecting passage for fluid, by (A) injecting a mixt. of steam and oxygen-contg. gas at a temp. corresp. to the satn. temp. of steam under the formation pressure, and (B) extracting the hydrocarbons from the prodn. hole. Method is used esp. for extn. of heavy viscous oil (bitumen) from tar sand deposits. A controlled oxidn. takes place at much lower temp. than with normal in situ combustion. Carbonisation and coking the oil leading to blockage of the formation, with slow movement of the combustion front, is avoided. Improved visbreaking and mobility in advance of the front reduces blocking by excessive accumulation of viscous oil and allows increased yields of oil to be extd.

Title: Stereophonic program signals transmission system - using auxiliary carrier transmits signals over HF FM channel with difference modulation
Inventor: GRIESE HANS-JOACHIM DR
IPC: H04H1/00
Filed: 1975-06-26
Abstract: The auxiliary carrier is frequency modulated (6) by the difference combination of program signals, and the signal so obtained is added to the sum combination of the two program signals. The combination signal so obtained is used to modulate a main carrier. The amplitude of the auxiliary carrier is so controlled at the transmitter by a program signal amplitude, that when the program signal amplitude rises, the auxiliary carrier amplitude decreases and vice-versa. A matrix produces signals (A+B) and (A-B) from the signal imputs. The final modulator is a frequency modulator.

Title: Electronic switching circuit - connects parallel A.C. networks, or connects generators to network in operation
Inventor: BORN ECKHARD DIPL PHYS
IPC: H02J3/40
Filed: 1975-07-02
Abstract: A switching network for connecting generators in parallel, compares voltage phases of networks to be connected in a phase discriminator which generates a triangular voltage varying at the difference frequency of the two voltages. It delivers a switching command before the instant of phase equality. A triangular voltage is also applied to a differentiating circuit delivering a voltage proportional to the derivative of the triangular voltage. It is applied to a summator to which the triangular voltage is also applied. The summator is followed by a limiter which delives a tripping signal when its input voltage exceeds a specified minimum value. A logic circuit follows the phase discriminator and the limiter, which retransmits the switching command only when the tripping signal is present.

Title: Radioactive plant disposal by concrete embedment - then cutting into transportable blocks esp. by autogenous burning
Inventor: LIEHMANN GERHARD
IPC: G21F9/36
Filed: 1976-02-03
Abstract: Disposal of solid radioactive waste materials, esp. metal components such as valves, steel vessels and the like, consists of filling in the components with concrete and embedding them in concrete and then cutting or breaking them up. Pref. the resultant concrete blocks or objects are cut up by powder burning or powder fusion, esp. using exothermally oxidisable substances already mixed in the concrete. Method is used esp. for complete removal and disposal of nuclear power plants after their useful life. Individual large or small parts of the plant, for example, steam generators, are filled with concrete, surrounded with concrete and then cut up. This means that all the loose and difficult components, such as tube bundles, are held firmly in position during cutting. An additional advantage is than the amt. of exposed surface, emitting radiation, is very much limited since the greater part of the articles is covered and embedded in concrete which provides adequate shielding. Alternatively, saws may be used for cutting up the concrete blocks.

Title: Oil well drilling fluids - contg. ilmenite as weighting agent
Inventor: HUEBOTTER EARL E
IPC: C09K8/02
Filed: 1976-03-16
Abstract: Oil well drilling fluids based on oil, water or emulsions, contains added thickening agent, and ilmenite of particle size such that 85 wt % passes a 0.044 mm (325 mesh) sieve as weighting agent, in amount sufficient to give the required density. The ilmenite is of sufficient purity to have a density of 4.3 min. Fluid is used as coolant, lubricant, hydrostatic head, etc. in sinking of boreholes by continuous drilling. Ilmenite is harder than barytes and does not suffer particle size reduction with consequent increase in viscosity of the fluid during continuous circulation. Density is almost the same as that of barytes, allowing the same tables to be used to calculate the amt. required.
