Title: Self cleaning oil burner - is started by counterflow engine exhaust afterburner with oil evaporating dish upstream of oil combustion chamber
Inventor: LEISTRITZ HANS KARL DR
IPC: F23D5/02
Filed: 1976-02-25
Abstract: The self-cleaning oil burner is of the type which is started -up with the aid of the after-burner of a combustion engine and into which the oil is introduced (9, 8). The outlet chamber (13) of the after-burner is downstream of its counter-flow combustion chamber (1, 2, 3).

Title: Phase shifter for electronically controlled antenna - uses two mutually decoupled signals supplied in opposite propagation direction
Inventor: GOBERT JEAN DIPL ING DR
IPC: H01Q3/36
Filed: 1976-06-03
Abstract: The phase-controlled antenna consists of several individual radiators and its phase shift of two high frequency signals is controlled by an electronic device. The first signal is supplied to a controllable, non-reciprocal, ferrite phase-shifter (4) in its first propagation direction. The second signal is supplied to this phase-shifter in a different propagation direction. The two high frequency signals can be mutually decoupled by circulators (5, 6), typically two for each phase-shifter. Alternately different polarisation of the two signals transmission may be used for this decoupling. The non-reciprocal ferrite phase-shifter may be mounted in a waveguide with a signal coupler at both ends of the waveguide. The couplers may provide connection of mutually orthogonal, linearly polarised signals.

The shoulders (2a) are folded under the band, and the band has a number of transverse slots cut in it matching the pitch of the thread on the adjusting screws.
Patent DE-2630794-A1 (DE)
Inventor: LEONHARDT FRITZ PROF DR ING
IPC: E02C1/00
Filed: 1976-07-08
Abstract: The core area of the concrete parts is filled with a concrete with coarse-grained aggregate and low cement content. In contrast, the marginal areas are filled with a finer-grained aggregate and a higher cement content. The concrete parts are moderately prestressed by prestressing elements, and in fact a partial prestress of 20 to 50 % of the final prestress is applied to the prestressing elements before the greatest temperature difference is reached between the core temperature and the temperature in the marginal areas approximately at the time of the transition of the concrete from its gel-like state into the rigid state. The method permits a reduction in the thermal stresses occurring and an increase in the abrasion resistance.

Title: Power tool-shaft coupling overload safety device - switches off power supply when maximum safe torque is exceeded
Inventor: EPP PETER
IPC: B25J19/06
Filed: 1977-04-22
Abstract: The safety system for a hand operated manual tool such as a welding tool used on a vehicle production line, cuts off the power when the tool is released, to avoid damage. Two shafts (1, 2) are connected by a coupling which includes a flange (4) on the end of the first shaft (1) which fits into a recess in the flange (3) of the second shaft (2). Pins (11) projecting from the periphery of the first flange (4) engage triangular holes in the walls of the second flange (3). Six equally spaced compression springs (8') hold the pins (8) in the vertex of the triangular hole. When the torque transmitted between the shafts exceed a predetermined limit, the force on the pin (11) overcomes the spring loads so that the pin (11) rides up the side of the triangular hole and the two flanges (3, 4) approach each other. This motion actuates a lever (19) mounted between the flanges which then actuates a switch (20) to cut off the power supply.
