Title: Recovery of hydrocarbons from underground deposits - using a hot gas generator at the bottom of a borehole
Inventor: HAMRICK JOSEPH T
IPC: E21B36/00
Filed: 1977-08-16
Abstract: Extraction of hydrocarbon or other materials from underground deposits using a hot gas generator at or near the deposit level, which is continuously supplied with fuel and oxidising agent, and which produces steam and/or other hot gases to heat the oil in the deposit. The fuel and oxidising agent are passed down the borehole through pipes, and the hole is sealed off above the generator by an inflatable packing, the hot gases passing out through the bottom into the formation. Damage to the pipes by heating and expansion when steam is pumped down from the surface, and cooling of the steam during passage are avoided. The system can be used at below the max. depth of 1000m. possible with steam. When excess hydrogen is used as fuel, its low mol. wt. and high diffusion rate allows easier penetration into the deposit and more rapid heating of a large volume. In presence of natural catalysts, hydrogenation of oil occurs, with a further reductive viscosity.

Title: Football shoe preventing deflection of the foot - increases accuracy of shots and passes without loss of flexibility
Inventor: DASSLER ADOLF
IPC: A43B5/02
Filed: 1977-09-17
Abstract: At least one of the components forming the bottom of a sports shoe;- the outer sole, the inner sole and possibly a reinforcement piece, and at elast in the front zone of the shoe, is produced froma resilient, elastic material. This component, is, at least locally,dished transversely to the length of the sole and arched downwards. The dished zone at the front of the sole also is arched in the lengthways direction, so that a slightly spherical effect is obtd.with the arching extending across the full widht. In the zone of the front sole, the inner sole is made from resilient elastic material, such as polyamide,over the length extending to the bending line. In the heel zone a conventional inner sole material is ued. The design is specifically intended for a football shoe which stiffens the foot downwards when the ball is kicked to make a shot or a pass, so that deflection of the foot is prevented without any loss of flexibility of the shoe and without its weight being increased. The stiffening of the foot ensures much greater accuracy. The weight can be reduced to less than 250 g. Abrasion of the instep is prevented as well as the brusing which happens with conventional shoes.
Patent DE-2745961-A1 (DE)
Inventor: ECHLE BERNHARD DIPL ING
IPC: A61L2/20
Filed: 1977-10-12
Abstract: A mixture of steam and a sterilising substance is used for the purpose of sterilisation inside a sterilisation chamber (1). After the sterilising process, the mixture is pumped by a vacuum pump (6) into a condensation vessel (3) and from there through a second branch (15), with a first shut-off valve (11) being open, back into the sterilisation chamber (1). The condensation vessel (3) is cooled down to a temperature above the liquefaction temperature of the sterilising substance, but below the liquefaction temperature of the steam. At the same time, the proportion of steam in the condensation vessel (3) is condensed and drained via a second shut-off valve (11') into a liquid collection vessel (4). The second shut-off valve (11') is then closed and the condensation vessel (3) is cooled by means of an evaporator (9) below the liquefaction temperature of the sterilising substance. The method permits reliable separation of water or steam and sterilising substance. As a result, it is possible to use considerable amounts of steam in addition to the sterilising substance for the sterilising process in order to exert, for example, an additional bactericidal effect on the goods to be sterilised present in the sterilisation chamber. <IMAGE>

There may be a series of similarly serrated blade holders, all meshing with a single wormgear wheel. The wheel can comprise a central ring engaged by the sectored serrations. This permits continuous blade holder angle adjustment, even with multiple blade holders.
Patent DE-2755579-A1 (DE)
Inventor: DUCKWORTH CLIFFORD
IPC: D06B19/00
Filed: 1977-12-09
Abstract: In a process for pad-dyeing textile material in sheet form on a pad-mangle having a short-liquor trough using aqueous padding liquors which in addition to dyeing assistants contain dyes which develop an affinity for the fibre only on heating of the padding liquor to temperatures above 60 DEG C, the cold padding liquor is passed on the way to the pad-mangle trough through a continuous heater, raising it to the treatment temperature which is above 60 DEG C. A short-liquor (economy) pad-mangle usable for this purpose has a continuous heater situated in the liquor feed line between the reservoir tank and the short-liquor trough and is provided with a means for setting the temperature of the padding liquor flowing out of the continuous heater into the short-liquor trough. The process is of special relevance for the continuous pad-dyeing of cotton textiles, since it makes it possible, despite the single-stage method of operation, to achieve the same success as requires a multi-stage treatment in the case of conventional pigment padding processes.

Title: Industrial smoothing iron installation - has temp. regulator remote from iron making possible use of electronic circuits
Inventor: DOKOUPIL JIRI DIPL ING
IPC: G05D23/24
Filed: 1978-05-26
Abstract: The temp. detector positioned in the sole plate of an industrial smoothing iron consists of an NTC resistance, and is connected to a temp. regulating device arranged completely separately from the iron and connected to the power supply. The iron has a steam supply controlled by an electromagnetic valve via a microswitch in the iron handle, which is aligned parallel to the sole plate. The surface of the sole plate is given a micropore coating by a thermal atomising process. The edges of the sole plate are protected by a hard trim of aluminium oxide, and the whole is surfaced with PTFE. Problems arising in industrial irons from the use of bimetallic thermostats and their hysteresis, together with the relatively large heating power which has to be controlled, and the much higher frequency of use are overcome and the life time of the iron is extended.

Title: Address decoder for dynamic semiconductor memory - has addressing vertical FETs, each with auxiliary transistor whose drain terminals are coupled to FET source terminals
Inventor: MEUSBURGER GUENTHER DIPL ING
IPC: H01L29/808
Filed: 1978-08-31
Abstract: The address decorder is produced as a MOS integrated circuit. The number of address field-effect transistors corresponds to the number of address bits. Each transistor gate is controllable via an address line. These transistors are connected with a feed transistor to form a NOR-gate, whose signal output serves to activate the addressed memory.
