Title: Automatically initiating in situ combustion with downhole burner - having flame-out detector and ignitor responsive to thermocouple detecting combustion
Inventor: HOWARD CURTIS EUGENE
IPC: E21B36/02
Filed: 1978-03-17
Abstract: A method for initiating heat in a well in a subterranean reservoir for recovering petroleum comprises suspending an elongated open ended combustion chamber in the well and mixing an air-fuel mixt. in the chamber. An ignitor ignites the mixt. in response to a thermocouple adjacent the ignitor detecting no combustion in the chamber. Upon detection of combustion by the thermocouple the ignitor is extinguished to provide an automatic, reliable and flame-out proof method for initiated heat. Used for producing well bore in counter-current in situ combustion process and air injection well bore in forward in situ combustion process. The ignition system can be used in heavy oils, tar sands, oil shale, partic, in deep wells. A highly agitated combustible mixt. is provided by supplying air to the combustion chamber through air ducts in the chamber wall. If flame-out is detected then reignition is effected.

Title: Shorting closing time of steam valve for turbine - converting changing number of revolutions of rotation counter into inversely-proportional impulse pressure
Inventor: GROHROCK OTTO ING GRAD
IPC: G05D13/52
Filed: 1979-01-20
Abstract: The closing time of a steam valve for a steam turbine is reduced by a sudden decrease in load. The changing number of revolutions of a rotation counter is converted into an impulse pressure inversely proportional to it. The adjusting piston of the valve (11) is set in dependence in the change in oil pressure in the impulse control line (17). The latter is assigned to a differential control (15) switched in parallel to the revolution control (12, 32). The differential control can be for an hydraulic steam turbine control. In which case, an oil chamber is divided into two volumes by a separating piston slidable against the force of a biasing spring.

Title: IC engine with over head cams - has tappet with face inclined to give unidirectional thrust on one side only
Inventor: KUHN PETER R DR ING
IPC: F01L1/12
Filed: 1979-04-19
Abstract: A cam on an overhead camshaft moves a triangularly shaped tappet on top of the valve shaft. The cam runs on an inclined face of the tappet which has a horizontal base sitting on the valve shaft and a vertical face running on a guide block. The inclined face is at angle such that the normal between it and the cam is such that the sideways thrust is always in the same direction and passes through the surface of contact between the tappet and the guide block. This prevents tipping of the tappet with a guide block on one side only.

Title: Monitoring vehicle exhaust emission while on dynamometer - using regulated exhaust extraction to collector via three=way valve
Inventor: STRAUB WERNER
IPC: G01M15/10
Filed: 1979-09-25
Abstract: An emission monitoring method for vehicles involves pumping fuel to the injection or carburation system of the vehicle from an external tank (8) whilst the vehicle is on a dynamometer. The exhaust gases are gathered via a tube (11). The method is more economical and easier to implement than a constant volume sample test, but produces sufficient accuracy of emission parameters derived from measured conc. values. A small fraction of the exhaust gases pass to a collector (14) via the tube (11), a vol. divider (12), and a three-way valve (13). When the collector is full, its contents are passed via the valve (13) to an analyser (16). The vol. divider contains a wt. or spring loaded baffle plate arrangement and releases most of the exhaust gas to the atmosphere after mixing it with air.

Title: Central heating fuel economy system - has heat-up time circulated from difference between internal and ambient temperatures
IPC: G05D23/24
Filed: 1979-09-27
Abstract: The system economises fuel in a building central-heating system by cutting out heat-generation during slack periods and cutting it in again in sufficient time before demand resumes. Ambient temperature and also mean internal temperature are taken into account in determining the appropriate moment. The heat-up time is a function of the colling-down time elapsing after cut-out and also of the difference between internal and external temperatures, and of a constant. The latter is arrived at from a base value by measuring the actual time for heating-up and comparing it with the calculated value.

Title: Temp. control system for absorption heat pump - regulates heat of driver to control flow of heat exchange fluid
Inventor: JANSSEN HARALD DR
IPC: G05D23/20
Filed: 1979-12-04
Abstract: The absorption heat pump uses a driver heated by an oil or gas burner and supplied with a rich solution of the refrigerant. Between the absorber and the driver is a pump so that the weak solution passes through the primary side of the main heat exchanger. The temp. of the driver is kept constant by regulating the burner and the flow of the liquid is controlled by the rated temp. The supply of the weak solution to the absorber is controlled by an adjustable throttling valve. This valve is controlled by the level of the weak solution in the driver. The amount of liquid pumped is varied in accordance with the heat requirement.

Title: Interferometric examination of distorting optical elements - by forming master hologram with reference and object beams, for strongly refractive components
Inventor: ROTTENKOLBER HANS DR ING
IPC: G01B9/021
Filed: 1980-03-05
Abstract: An interferometric arrangement for quantitative evaluation of variations from the shapes of the of optical elements enables full holograms to be formed of strongly refractive and distorting elements over their entire extent. A laser (1) beam is divided into object (5) and reference (6) beams. The element under examination is placed in the object beam before a light sensitive layer (18) on which is a hologram reconstructed from the object beam and obliquely incident reference beam. The wavefront corresp. to a reference object is effectively stored in the hologram for comparison with that of the test object. This is achieved by inserting a diffusing plate (16) in examination. This ensures a uniform distribution of high intensity at the hologram.
Patent DE-3016354-A1 (DE)
Title: Isolating current transformer for accurate measurements - has integrating circuit and control winding for rapid change of magnetisation
Inventor: HAXEL KLAUS DR ING
IPC: G01D3/06
Filed: 1980-04-28
Abstract: The transformer is in two sections. The compensating winding is switched in alternate half cycles by solid state switches with alternating polarity across a d.c. supply. The switching only takes place during the short intervals when the current to be measured is changing rapidly. At such times the integrator is switched off. When the compensation current is very small the switch between the common point of the compensating windings and one input of the integrator turns on and an integration over a time period takes place. With low magnetising current and high permeability the leakage flux is very small during the integrating time. Thus primary and secondary windings may be spaced well apart to give the required galvanic separation.
