Title: Crimp connector for flat cables - with prismatic ridges at bottom and sharp edges at top of U-stamping
Inventor: KOENNEMANN ALFRED ING GRAD
IPC: H01R4/24
Filed: 1975-04-08
Abstract: The crimp connector for the flat connectors of a ribbon-type cable is a U-shaped metal sheet stamping with a number of prismatic ridges enclosed across the flat bottom. The free ends of the legs are pointed to form a sharp edge so that they penetrate the cable insulation from the top as well as the prisms from the bottom, when the connector is compressed around the cable by a crimping tool. This provides a more reliable contact than the one raised tooth at the bottom of conventional crimp connectors. The transverse prismatic ridges also protect the connector from being pulled off by tension.

Title: Rotary cement kiln with vertical pellet calciner - having air inlet valve in transfer duct between calciner and kiln
Inventor: GOTTLIEB STEVEN
IPC: F27B1/20
Filed: 1976-01-20
Abstract: In the base of the vertical pellet calciner is an oscillating grid through which the pellets discharge into a transfer funnel and a duct leading to the downstream rotary kiln. Off-gases from the kiln pass into the calciner body through external pipes with a small portion flowing upwards through the solids transfer duct. In the latter is a valve which can be used to admit cold air to join the stream of kiln gases flowing upwards through the solids transfer funnel. This air, as well as serving to cool the grid mechanism is used in the calciner as combustion air and enables the primary air supply to be reduced in proportion and the distribution of fuel combustion zones within the calciner to be controlled. The pellet feed to the calciner may be mixed with coal dust slurry to aid fuel economy. For use in cement kilns with pellet calciners feeding the kiln. Accurate control of calciner, temp. is possible avoiding unwanted sintering. Max. fuel economy is obtd. by good control of primary air supply.
Patent DE-2611502-A1 (DE)
Inventor: BROSZINSKI HANS-JUERGEN DIPL I
IPC: B61L19/06
Filed: 1976-03-18
Abstract: In a push-button and track-diagram railway signal box, the storage relays of the element groups for identifying start loading, destination loading, direction loading and position loading of the respective groups are not switched directly but rather via connecting relays which are acted on during the approval test. The approval test takes place after the route search has been successfully completed; this requires separate switching levels for the route search and the approval test. As a result of this separation it is possible to use long-life, quickly-switching switching means, for the route search, preferably electronic switching means. In the approval test, only the connecting relays (FA2, DA, FA2<*>, ZK2, DK) of the element groups (ES2, ED) which are actually involved in a route, and thus also only the associated storage relays, are activated. The connecting relays are fault current-excited, as soon as the acceptability of the entire route has been established, and only switched after further approval conditions have been tested. They are mainly of low-impedance design so that a greater number of them can be switched simultaneously in series. <IMAGE>

Title: Cooling mixer for granular and gel-form synthetics - has vanes inclined to exploit whirlpool motion during agitation
Inventor: HARTMANN JOHANN
IPC: B29B13/04
Filed: 1976-07-08
Abstract: A cooler mixer for the prepn. of granular, gel-type or similar synthetic materials has, inside the container, at the bottom, a rotary mixing arm, and above this, spaced out around a circle, stationary vanes forming cooling compartments through the double walls of which a refrigerating medium is circulated. The vanes extend radially and are inclined obliquely to the bottom of the container, between two support rings. One of these is positioned some distance from the inside wall of the container whilst the other is located close to the axis of the container and surrounds it. The supporting rings have, at least in places, channels for the cooling medium and the outer ring is attached by ribs, >=2 of which are conduits for the cooling medium. The height of the supporting ring can be adjusted on the ribs and the posn. of the ribs relatively to the machine frame can also be varied. The vanes are placed so closely behind each other and their inclination is such that they partially overlap each other. The mixer takes fully into account the whirlpool condition brought about by the vertical motion of the mass which is superimposed upon the rotary motion. The material flows across the inclined vanes with sufficient press. to ensure an adequate transfer of heat and shorten considerably the necessary cooling time.
