Title: Handle fitting for saucepans etc. - has interengaging spring and bracket with recesses for easy replacement
Inventor: ANDRESEN HEINRICH
IPC: A47J45/07
Filed: 1977-03-28
Abstract: The easily detachable handle for saucepans and other cooking pots includes a holder (3) which has two upstanding brackets (7) which are attached diagonally symmetrical with each other and have recesses which are open on opposite sides and are cut away towards these openings. A spring (6) or spring wire can be fitted in the actual handle so that the latter can be set on the saucepan wall with the spring wire between the two parallel brackets (7) and can then be secured by a slight rotational movement which causes the spring to pass into the recesses and engage behind the rear-cut sections. This engagement can be clearly sensed and the handle is then secured. If required it can be released by a more forceful rotary movement in the opposite direction so that a damaged handle can be readily replaced without special tools or skill.
Patent DE-2717061-A1 (DE)
Title: Target practice hit recording equipment - has horizontal or vertical stripe target with measuring markings on both sides
Inventor: FRITZ WILHELM
IPC: F41J1/00
Filed: 1977-04-18
Abstract: The equipment for hand weapon target practice enables the marksman to find the most suitable body position for accurate firing. The target (12) is a vertical or horizontal strip fastened to carrier sheet (11). In certain distances to the right and to the left of the target are several measuring markings (13) parallel to the target. During aiming practice the marksman brings his weapon into bearing with the target, whereupon the line of sight is temporarily obscured by the instructor. After reinstatement of the line of sight the marksman can see whether, and how much he came off his target and can readjust his firing position. A similar procedure applies for the actual firing.

Title: Sludge conversion to compost - in bio-reactor with concurrent flow of air
Inventor: NEMETZ HERBERT
IPC: C05F17/00
Filed: 1977-05-12
Abstract: Raw sludge from sewage plant, mixed with carbon carriers, is converted into compost in an aerobic reactor in which the sludge descends in concurrent flow with air. The CO2 content of the waste gas is measured and the air flow rate is controlled thereby. A suction device draws the air in a downward direction through the material in the reactor. Contrary to the conventional counterflow principle, the concurrent flow causes the sludge to rot without causing stoppages by excessive humidity or uneven air distribution in the rotting material.

Title: Plastics- or rubber-foam coating for tennis racket strings - applied by immersion or spraying, and treated with serrated rollers after setting
Inventor: REPPERT RUEDIGER LOTHAR VON DI
IPC: A63B51/02
Filed: 1977-07-13
Abstract: The parent patent described mfr. of coated tennis racket strings (which may consist of natural gut, plastics, twins or wire) by applying >=1 layer of soft, pref. foamed, plastics or synthetic or natural rubber, by immersion oating. In this adn. coating is effected, with the racket ready-strung, by immersing the whole racket whose frame has previously been wrapped into an easily detachable adhesive tape, into the coating soln. Alternatively, coating is carried out by spraying coating soln., before stringing the racket, onto the strings until the coating has the desired thickness, and then roller-treating the gradually setting coating with a serrated roller. The treatment confers adequate roughness to the strings.

Title: Central heating control equipment - has computer to compare temp. of solar heater, heat exchanger and heat accumulator and to compare values with that of circulating water
Inventor: KEHL ALBIN DIPL PHYS DR
IPC: F24D19/10
Filed: 1977-10-08
Abstract: The control equipment is for a central heating system having a solar energy collector forming a heat-first source and a heat exchanger acting as a second heat source working with the environment. A heat accumulator is charged by the two sources, and a heat pump delivers energy from the sources or the accumulator to the heating circuit. The control equipment controls the heating power as a function of the difference between the heating water temperature and a datum value at two or more levels. It has a computer for comparing the temperatures of the heat sources and the accumulator at each level to a predetermined monitoring pattern. It also compares these temperatures with those of the circulating water of the user, to arrive at the best system for economic operation, determining an order of functioning for the regulator.

Patent DE-2802881-A1 (DE)
Title: Conveyance of natural gas through a pipeline - having sections between which the gas is compressed, gas cooled from travel along a section is used to cool the compressed gas
Inventor: LINDE ROBERT VON DIPL ING
IPC: F17D1/04
Filed: 1978-01-24
Abstract: Real gases are conveyed over long distance by a pipeline having a number of sections connected in series. Between the sections compressor stations compensate for pressure loss in the preceding pipeline section. The pressure and temperature of the gas as the start of each pipeline section are selected so that a lowering of gas temperature results from the drop in pressure in the pipe section. This low temperature gas is used for recooling the gas heated by compression, before entry into the next pipeline section. The method of the invention provides a more economical conveyance of natural gas over long distances. It is based on the concept that a pipeline without external heat supply behaves thermodynamically like a throttle. Such throttling occurs with constant enthalpy. While the temp. of an ideal gas does not vary during throttling, throttling of a real gas causes a temp. variation between the molecules, which is termed a Joule -- Thompson effect, as a result of the Van der Waal's cohesion forces. This effect produces considerable cooling of the gas at certain pressures and temperatures. This condition is utilised since the conveying capacity of a pipeline of given diameter is considerably increased by conveyance at low temperatures because of the small specific volume.

Title: Self-centering three-jaw drill chuck - has lock ring to prevent rotation of ball thrust race positioned by screwed cap
Inventor: ROEHM GUENTER HORST
IPC: B23B31/12
Filed: 1978-04-26

Title: Shuttleless loom selvedge formation - by securing each pick between the turns of two intertwined binding threads
Inventor: SHINDO AKIO
IPC: D03C7/08
Filed: 1978-07-21
Abstract: A selvedge-forming device for a shuttleless loom comprising a first unit for twisting together two binding threads after the insertion between them of one end of the weft, and a second unit at the other edge of the fabric for similarly twisting together two binding threads between which the second end of the weft has been laid. The units are so arranged that the two binding threads in each selvedge unit are all twisted together in the same direction. The arrangement produces similarly firm edges at both side of a fabric, with no tendency to rupture due to the extraction of all twist from a binding threads during selvedge formation.
