Title: Funnel shaped barge propeller housing - has ear shaped shroud enclosing double conical restrictions forming water jet
Inventor: KAUFER NICOLAUS
IPC: B63H5/14
Filed: 1976-09-09
Abstract: The barge has its propeller (6) housed inside a shroud (1) attached to the hull so as to form a tunnel (3e giving a jet effect of the water driven through it by the blades. This shroud widens outwards (8) at first, at the water entry end. The shroud also partly encloses this portion, and has a very gradual increase in size, giving a funnel effect, then increases more abruptly, forming an ear shape. The slope of the wide part (8) is between 20 and 50 deg., preferably between 35 and 45 deg. near the bottom edge (9) of the funnel. This reduces by 5 to 35 deg., preferably 10 to 20 deg..

Title: Switching pulse generator for control of hotplate - has controllable clock generator providing infinitely variable on-off switching ratio
Inventor: GERUM ERICH
IPC: G05B11/28
Filed: 1976-09-18
Abstract: Electronic controller regulates the on-off ratio of switching pulses. Between the output (10) of a first circuit (1) producing square-wave pulses and a clock generator (9), is a second circuit (2) with two parallel branches (3, 4) each containing a variable resistor (5, 6). A changeover switch (14) connects either the first or the second parallel branch to a supply. Partial resistances are tapped from the two variable resistors and united at the clock generator input (11). The tappings are coupled so that resistance variations in the two parallel branches are always approximately inversely proportional to each other. The charging currents dependent on the resistance in the two branches vary the clock frequency which is used to control the square wave pulse circuit, and the pulse frequency of this circuit is always lower or at most equal to that of the clock generator.

Title: Implantable electrical terminal for organic tissue - is porous to intermesh with tissue without formation of fibrous tissue encapsulation
Inventor: ENGER CARL C
IPC: A61N1/05
Filed: 1977-01-20
Abstract: The terminal includes an electrically conductive portion having a surface for contacting the tissue electrolyte. This surface is surrounded with an inert non-absorbable porous material having interconnected and continuous pores with a dia. 10 - 500 mu. This permits the ingress of blood capillaries and intermeshing with the tissue without the formation of a fibrous tissue interface. Electrolytes in the tissue can thus come in contact with the electrically conductive portion of the terminal. For implanting in living human or animal tissue, as a component of e.g. a heart pace maker etc.. The living tissue does not build up a defensive fibrosis around the terminal which would insulate and isolate it from the vascularized tissue.
