Patent DE-2636565-A1 (DE)
Title: Heating tar sands in situ - by electrical induction to assist oil extraction
Inventor: FISHER SYDNEY T
IPC: E21B43/24
Filed: 1976-08-13
Abstract: Natural underground deposits of crude oil, esp. mixed with e.g. tar or bituminous sands are heated by electrical induction heating of a limited section of the deposit to assist extraction of the oil. Heating is continued until the temp. in the heated section reaches a given value and may be continued during extraction of the oil. It is carried out by passing an alternating current of predetermined voltage, current intensity, wave form and frequency through a conductor which encloses part of the formation. Heating is achieved without affecting the oil present by combustion or carbonisation.

Title: Colour filter panes for underwater illumination of fountains - is fitted with blades driven by free fall of water turning panes in opposite directions
Inventor: DROST BERNHARD
IPC: F21S8/00
Filed: 1976-11-05
Abstract: Each colour filter pane is driven by its own blades making a rotary movement round the axis of the fountain producing successive colour changes in the lighting of the fountain. Two colour filter panes (1, 2) are positioned without contact in planes above each other with each colour filter pane having its own buoyancy unit (5, 6) whereby the upper pane is held in a surfaced position, with the lower pane held in a submerged position. Each of the colour filter panes is equipped with several drive blades projecting from the water of the fountain and inclined in the direction of the turning movement required. The blades are subjected to kinetic energy by the free fall of the water playing in the fountain which drives the colour filter panes (1, 2) in opposite directions.

Title: Vertical die casting machine - having two:part casting sleeve with lower movable out of alignment for charging
Inventor: UENO TOYOAKI
IPC: B22D17/12
Filed: 1977-02-10
Abstract: In a vertical die-casting machine, the casting sleeve is in two parts.

Patent DE-2715816-A1 (DE)
Title: Spring core mattress with several protective layers - has two rigid reinforcement layers ensuring greater distribution of stress points
Inventor: BERTHOLD FRANZ XAVER
IPC: A47C27/05
Filed: 1977-04-07
Abstract: The spring core mattres includes a more rigid but still deformable reinforcement layer (9) which covers the spring core and is in turned covered by a softer foam layer (10) with this softer layer being covered by yet a further more rigid reinforcement layer (11) with another softer layer (12) lying between the latter reinforcement layer (11) and the outer cover (3). The provision of a second reinforcement layer ensures that any punctiform stresses can be more evenly distributed. The inner reinforcement layer is thus only subjected to very slight deformations and indentations so that there is practically no relative movement between the spring core and the lower reinforcement layer so that the latter is protected from friction wear and tear and can thus be made of a cheaper material.

Title: Elastomeric coupling to fit glass components tightly together - comprises a sleeve having a tapering outer surface and cylindrical inner surface; used esp. for laboratory appts.
Inventor: KOHLER HELMUT PROF
IPC: F16L49/02
Filed: 1977-06-27
Abstract: Connector for fitting two glass components of different dia. together e.g. a tapering glass stopper into a glass bottle or glass tube with tapering mouth is made of elastomeric material and fitted between the glass component with greater dia. and hat with smaller dia. The connector is a sleeve which has a conical outer surface and an inner cylindrical surface; the inner dia. being 0.5-5, pref. 1-2 mm smaller than the smallest dia. of the neck of the bottle (or of an even smaller-dia. extension e.g. a cylindrical extension of the neck of the bottle). Used e.g. for assembly of glass equipment for chemical laboratories. In contrast with direct glass-on-glass connections, high dimensional accuracy of components to be connected is not critical. The connection achieved by the elastomeric coupling, is not rigid, hence less liable to damage by inadvertent rough handling.

Title: Resonance controller for automatically tuning earth fault coil - has aND=gate receiving trigger signal and signal representing increasing star point to earth voltage for limiting latter
Inventor: WEBER WALTER
IPC: H02H9/08
Filed: 1978-01-19
Abstract: The resonance controller automatically tunes earth-fault coils in power networks and has a trigger supplied with the star point to earth voltage. The trigger's threshold is slightly lower than that at which an earth fault is indicated. An AND-gate logically combines the trigger's output with a signal representing an increase in the star point to earth voltage whilst the coil is being adjusted in the absence of an earth fault. The AND-gate produces a signal that terminates the coil's tuning.
