Title: Electric toaster with bimetallic timer switch - has auxiliary heating and selective switching and by=pass of additional resistors or diode to supply
Inventor: NEUBAUER HORST DR
IPC: A47J37/08
Filed: 1979-01-20
Abstract: An electric toaster has one to two button controls and a bimetallic timing switch. The auxiliary heating of the bimetallic heating element is connected in series with the heating element of the toaster. The toasting surface can be adjusted between an operating position and an ejection position, and reset by a lever. The ejection occurs when the metalic switching element is buckled by thermal stresses at the end of a heating phase. The toaster is switched off when the toast has been ejected. There is an additional power consuming element selectively switched in parallel with the bimetallic auxiliary heating. This element can be a fixed resistor or a switched diode. The toaster can be connected directly to the supply bypassing the auxiliary heating of the metallic switching element and the additional consuming element.

Title: Helicopter rotor blade cyclic and collective pitch control - adds linear actuator movements to position swashplate which moves axially to set pitch and tips
Inventor: VOGT ALFRED DIPL ING
IPC: B64C27/68
Filed: 1979-06-22
Abstract: The pitch of helicopter rotor blades is set by a swashplate on the rotor shaft and connected to each of them by a linkage. The swashplate moves axially to set collective pitch and tips about two axes to set cyclic pitch for fore-and-aft and lateral control. The swashplate is connected by rods to two pairs of linear actuators, electric or hydraulic, which set cyclic pitch. They are fixed to a unit which is moved axially on the rotor shaft by the collective pitch actuator. Thus the swashplate axial position and tilt is the linear sum of the collective and cyclic actuator settings. The actuators are controlled to respond linearly to the control column position, e.g. by means of potentiometers attached to it.

Title: Central heating consumption meter circuit - has temp. sensor leads conducting signal in opposite direction to initiate electrically-operated valve assigned to radiator
Inventor: LOEWENHOFF PETER DIPL ING
IPC: G01K17/06
Filed: 1979-07-05
Abstract: An electrical circuit for a heat consumption meter counteracts deliberate or accidental interference with the leads. At least one temp. sensor is installed in the region of each radiator used in the central heating system. The measured values are conducted to the meter via measuring leads. The radiator has an electrically-operated valve for turning-on the heating flow. The valve is controlled by a signal conducted via the temp.-sensor measuring leads. The latter can form part of a circuit carrying currents flowing in various directions. The polarity arising on the measuring leads for transmitting the sensor's measured values can be temporarily switched round to transmit the control signal. The resistance of the current carrying circuit can be substantially smaller in the control signal transmitting direction than in the other direction.

Title: Testing lubricant film formation under operating conditions - using tapered roller measurement bearing with axial and radial displacement
Inventor: MUENNICH HERMANN DIPL ING DR
IPC: G01N33/30
Filed: 1979-07-14
Abstract: A lubricant performance testing device with a measurement bearing in the form of an axial oller bearing enables the film formation qualities of a lubricant under frictional contact to be evaluated. The measurement bearing is an axial tapered roller bearing (1) with distortion-free bearing discs (9,10) and tapered rollers (11) which can be displaced radially using nuts (16) on the thread of a bolt (14) on which the bearing slides. The roller rotation axes are perpendicular to the bearing axis. One bearing disc (9) has a plane bearing surface. The radial displacement of the tapered rollers may alternatively be accomplished using hydraulic pistons. The bearing housing disc (9) may be displaceable in the axial direction. The device measures the frictional moment over revolution rate and oil film thickness over revolution rate characteristics.

Title: Magnetic core designs using flat stampings - has parallelogram shaped or trapezoidal portions adjacent to one another tacked by straight weld (HU 28.9.79)
Inventor: SARINGER KALMAN
IPC: H01F27/245
Filed: 1979-08-10
Abstract: The core stampings of uniform thickness for a magnetic core construction, for transformers or coils, are produced in a variety of shapes each having the common features of symmetrical parallelogram sections, with some portions bending into oblique sections, so that they fit together to make contiguous chevron patterns and thus may be built up into various sizes.

Title: Fastening short circuiting rings on switching magnets - securing to magnet core by contactless laser welding
Inventor: DEUTRICH JUERGEN DIPL ING
IPC: H01F7/12
Filed: 1979-12-14
Abstract: The short circuit rings and their fastening on switching magnets are exposed to various very high requirements, combining a high electric conductivity with mechanical strength for a very large number of switching operations. For this purpose a laser welding is used for securing the short circuiting rings to magnetic cores, or armatures, of both solid or laminated type. When the short circuiting ring is to be inserted in grooves of pole surfaces, the ring is secured in the grooves by a number of spot welds, or by a seam weld, using a laser radiation directed orthogonally to the pole surface of the magnetic core. When the ring is formed by a suitable piece of wire, annularly bent and welded at abutting ends, laser welding is also used for the wire section it ends after has been inserted in the pole surface grooves.
