Title: Diesel engine driven heat pump - uses heat exchange with pump pressure side, engine cooling water and exhaust gas to generate hot water or air
Inventor: CREDE HELFRIED DIPL PHYS
IPC: F02G5/00
Filed: 1978-02-11
Abstract: The diesel engine driven heat pump is used to operate heat consuming domestic appliances such as washing machines, dishwashers and laundry driers. The water or air supply of the domestic appliance is in heat exchanging contact with the pressure side of the refrigerant circuit of the heat pump. It is also in heat exchanging contact with the cooling water of the diesel engine and the exhaust gases of the diesel engine. The water is supply of the domestic appliance is fed initially from a hot water boiler of the heat pump system or brought into heat exchange contact with it. Subsequently it is operated with the diesel engine exhaust gases.

Title: Double-action vacuum cleaner mouthpiece with brush strips - has tight seals between different parts preventing dirt from clogging adjustment mechanism
Inventor: STETTNER GERHARD ING GRAD
IPC: A47L9/06
Filed: 1978-02-16
Abstract: The perimeter of the mouthpiece plate (2, 8) tightly adjoins the inside of the mouthpiece hood (1). The hood engages over both the plate and two parallel vertically adjustable brush strips (5) which are designed to move up and down through slits in the plate (2, 8). The walls of the slits adjoin the bristles of the brush strips (5) and dirt is prevented from penetrating into the inside of the mouthpiece where it could block the adjustment mechanism for the brush strip, since there is a tight seal both between the plate and the mouthpiece housing and between the plate and the brush strip.

Title: Electronic ampere-hour meter for electric vehicle - modulates and amplifies voltage drop followed by demodulation and integration
Inventor: RADU IONEL DR ING
IPC: G01R21/133
Filed: 1978-10-24

Title: Stabilising hydratable clay formations - using a carboxylic acid-chromium complex to prevent clay swelling and particle migration
Inventor: KALFOGLOU GEORG
IPC: E21B43/20
Filed: 1978-11-11
Abstract: Stabilisation of subterranean formations contg. hydratable clay against clay swelling and particle migration is effected by contacting the clay with an aq. soln. of a Werner-type Cr complex (I) in which trivalent Cr atoms are coordinated with a carboxylic acid ligand contg. a 2-8C (pref. 2-4C) hydrocarbon radical, to form a polynucleated Cr complex on the surface of the clay particles.

Patent DE-2855338-A1 (DE)
Title: Typewriter with spring oscillatory system - generates type carrier driving force in opposition to spring
Inventor: PUCH DIETHELM DIPL ING
IPC: B41J7/34
Filed: 1978-12-21
Abstract: The typewriter has all essential power-consuming functions operated electrically, although the typing operation is by a separate drive for a single type carrier. With the aid of a mechanical spring-and-weight oscillatory system, the rest position of the carrier corresponding to the typing position for a selected character is adjusted by a force equilibrium between the carrier driving force and the spring force. A carrier driving force is generated in opposition to the spring force in the system. Movement of the carrier from a first rest position into a second one ready for typing takes place in accordance with the natural frequency of the spring-and-weight system. As a reference point for the reversal necessary for positioning the mid-point between the first and second carrier test positions is used.
Patent DE-2856853-A1 (DE)
Inventor: HUPACH HEINZ
IPC: B23P9/02
Filed: 1978-12-30
Abstract: In large diameter electric motors, in particular engines for hydraulic power stations, the rotors are constituted by segments (1) made up of many metal sheets stacked by covering over and placed on a rotor brace (6). Following the staggering of the sheet segments during the stacking to produce rings several meters in diameter, inaccuracies occur due to the summing up of the limits set to the division of the individual sheets and which are called stacking inaccuracies. Because of this, the bolt passage holes (3) are diminished by thereabout a few hundredths of a millimeter. To reinsure the exact measure of these passage holes it is proposed to reinsure real measure to the borings (3) made in the sheet segments (1) stacked by crushing their walls by means of a calibrating tool comprising a cylindrical body (12) provided with conical rollers at its circumference (14). The forming of cuttings is thus avoided and the power of the machine tool is notably less than that of machines utilized in known procedures. Moreover, the calibration of the holes can be executed with only one pass, thus entailing a significant saving of time in working.
