Patent DE-2933199-A1 (DE)
Title: Engine converting heat into mechanical energy - has rotor with thermally sensitive strips to shift centre of gravity when heated
Inventor: HAHN BERND ING GRAD
IPC: F03G7/06
Filed: 1979-08-16
Abstract: The rotor (1) is fixed to a horizontal shaft (2). Outer sections of the rotor parallel to the axis are made of material which expands when heated. A warm source (3a) heats one side of the rotor and a cold sink (4a) cools the other. The resulting expansion and contraction displaces the centre of gravity of the rotor to produce a moment about the axis which causes rotation. The hot and cold sources can act by blowing fluid onto the surface of the rotor. Alternatively fluid can flow through longitudinal channels in the periphery of the rotor. The fluid can flow in an open or closed cycle.

Title: Heat energy conversion to chemical energy - by cracking methanol in reactor heated with steam from nuclear reactor and heat exchange between charge and product
Inventor: KOCH CHRISTIAN DR
IPC: C01B3/22
Filed: 1979-12-13
Abstract: Conversion of heat energy to chemically bound energy is carried out in a reactor heated by steam from a nuclear reactor, in which a synthesis gas (I) contg. CO and H2 is produced from MeOH. The reactor (11) is heated with fresh steam from a light water reactor at 230-300 deg.C and the (I) formed is passed through a heat exchanger (21) cooled by the MeOH charge, which is first brought to a pressure above that in the reactor, so that no vaporisation of MeOH takes place in the heat exchanger. The MeOH is expanded again after the heat exchanger and before entering the reactor. The reaction is accelerated and a large portion of the heat of (I) is utilised for the process.

Title: Sugar free chewing gum of high water content - comprising gum-base, solid and liq. sorbitol and aroma agent
Inventor: SCHUETTE JOHANNES
IPC: A23G4/10
Filed: 1980-03-21
Abstract: Chewing gum comprises (wt.%) chewing gum base 18-35 (25-31)%, total water 8-4 (10-13)%; aromatising agents 0.7-2 (0.8-1.2)% and sorbitol 49-73%, esp. 27-33% solid sorbitol and 37-43% liq. sorbitol. The compsn. is made by warming the base material to 40-45 deg.C and kneading while adding solid sorbitol. When this has mixed in sufficiently, sorbitol dissolved in water is added, followed by the aromatising agent and opt. lecithin, and the whole mass kneaded. A sugar-free gum, esp. useful as a soft bubble gum, is prod. which does not require fatty acid derivs. etc. to be added as softener (the high water content provides adequate softening). A satisfactory degree of sweetness is achieved with a relatively small amt. of sorbitol, without need for any saccharin.
Patent DE-3011965-A1 (DE)
Inventor: SCHNEITER ALI
IPC: G04C9/08
Filed: 1980-03-27
Abstract: A time resetting operation in an electronic timepiece requires blocking of the stepping motor 1, and block of the mechanical type is avoided by the invention. A STOP switch 10 actuated by a time resetting stem of the timepiece sets to state "1" a flip-flop 11 which blocks gates 12 and 13 for controlling the passage of the pulses which drive the motor 1 through a feed circuit 2. The circuit 2 then passes a continuous current in the same direction as the last drive pulse. Thus, triggering of the continuous current leaves the position of the rotor unchanged. A counter 14 counts 1-second pulses and then resets the flip-flop 11, which causes the motor to resume normal operation. This avoids excessive discharging of the battery of the electronic timepiece if the user forgets to return the stem to its initial position after a time resetting operation.

Patent DE-3027936-A1 (DE)
Title: Terminal connector for telephone exchange wiring board - has wire wrap terminal pins in staggered rows permitting greater pin density
Inventor: BECKER HARRY ING GRAD
IPC: H04Q1/14
Filed: 1980-07-23
Abstract: The proposed terminal unit increases the number of connector pins without increasing physical size. In achieving this end the space required for the interconnecting wiring supports is not diminished. A desirable, increase in the number of terminal pins is achieved by staggering the pin positions (5) in the connector housing. The shift of half a pitch between one row and the next maintains the distance between adjacent pins whilst permitting a reduction in spacing between rows. Up to 50% more terminals per unit area are achievable with the proposed modification. The housing also has a slot (8) through which the end of a flat or ribbon connecting cable can be brought. Additionally, there are access holes (7) near some of the pin positions for entering further cables. The edges of the housing can be provided with support slots (23) for cables.

Title: Radial cylinder high pressure pump - has driving eccentric formed by two rings with varying diameter rollers between them
Inventor: SCHULZE WERNER ING GRAD
IPC: F04B9/04
Filed: 1980-10-27
Abstract: The pump has a shaft (6) with an eccentric on the end of it. The eccentric causes pistons (9) in radial cylinders (10) to reciprocate. The inner part of the eccentric is a ring (12) attached to or made integrally with the shaft. The outer part is an annular ring (14) the outside surface of which acts on the shoes of the pistons. Rollers (17) between the two rings increases in dia. over one half of the circumference of the rings and decrease over the other half. This gives the required eccentricity with a friction gear effect which reduces the outer ring speed below that of the shaft.

Title: Method for increasing the efficiency in the use of primary energy for heating, hot water and power supply
Inventor: BORST ADOLF H
IPC: F02G5/00
Filed: 1981-05-23
Abstract: For supplying a building with heat, hot water and power a small combined heat and power plant is described, which is to be installed in the building, for example in a detached house, in place of a heating boiler. This plant comprises a number of small motors for driving electrical generators and a heat pump, which can be set in operation as required. The heating and hot water demand of the building is met in that heat for heating is provided from the surroundings by means, for example, of a gas engine-driven heat pump and that waste heat released from the drive motors is collected in a hot water tank and held ready to meet demand. In order to increase the service life of the motors designed as an internal combustion engine, the latter are kept constantly at operating temperature in that, for example, where air cooled motors are used, the cooling air of at least one constantly running motor is utilised to maintain the operating temperature of the other motors. The proposed combined heat and power plant is capable of extremely flexible adaptation to the particular energy demand conditions.
Patent DE-3122954-A1 (DE)
Title: Open-celled plastics foam tampon for sanitary or medical purposes
Inventor: LEHR ALFRED VON DER
IPC: A61F13/20
Filed: 1981-06-10
Abstract: Described is a tampon for sanitary (hygienic) or medical purposes which consists of open-celled plastics foam. With such tampons the object is to use physiologically safe materials of construction and to arrange them in such a way that the tampons have good liquid-absorbing and -retaining capacity and, what is more, are sufficiently soft in the use state. This object is achieved when the tampons consist of a polyvinyl alcohol-acetal foam which has been cold pressed in the dry state. The material is preferably about 10-20% acetalised. One way of manufacturing the tampons is to soften open-celled foam of polyvinyl alcohol-acetal by moistening with water and stamping (blanking) from it tampon preforms (blanks) which are dried until the foam material has hardened and are then pressed in the cold state to form the final tampon.

Patent DE-3129895-A1 (DE)
Title: Sheet-metal hollow profiled bar, in particular upright profile for shelf units
IPC: A47B96/14
Filed: 1981-07-29
Abstract: An upright profile (2) for shelf units is to be designed as a sheet-metal hollow profiled bar which, having a substantially rectangular peripheral boundary, is provided on one peripheral side with an open longitudinal gap (9). In this case, the upright profile (2) designed as a hollow profiled bar is intended to correspond to box-type hollow profiles in terms of its resistance to torsion and thus satisfy the requirements of safety and inspection authorities in respect of providing statical evidence. At the same time, however, the advantage that the upright profiles (2) can readily be used for fastening wall parts or attachment rails is to be maintained. The longitudinal gap (9) is therefore bounded directly by three inner profiled wall sections (10, 11, 12) which each extend at a right angle to one another, and of which two inner profiled wall sections (10 and 12) have a relatively large spacing from the outer profiled wall sections (13 and 15) parallel thereto, while the third, inner profiled wall section (11) rests against the outer profiled wall section (14) parallel thereto. In this case, it is possible for the third, inner profiled wall section (11) to adjoin one profiled wall section (10) of the two further inner profiled wall sections (10 and 12) integrally on one side, while its free longitudinal edge (18) on the other side is overlapped, without clearance as far as possible, by the free longitudinal edge (19) of the other profiled wall section (12) of the two further inner profiled wall sections (10 and 12). <IMAGE>
