Patent DE-1725024-A1 (DE)
Inventor: MORSE JOHN FRANKLIN
IPC: F16H59/02
Filed: 1967-01-19
Abstract: 1,119,587. Change-speed control. MORSE CONTROLS Inc. 8 Dec., 1966 [28 Jan., 1966], No. 54937/66. Headings F2D and F2K. A hand-operated change-speed lever 11 adapted to range a six-speed automatic transmission comprises an arm 70 extending through a slotted plate 14 presenting six shift stations (11-1 to 11-6), Fig. 2 (not shown), and a hub portion 23 formed with a slot 59 through which passes a shaft 24 carrying a journal sleeve (65), Fig. 7 (not shown), to which the hub is connected by a resilient bushing 58 allowing pivoting of the lever 11 about the mirror axis of the slot 59 against increasing resistance from the bushing, but preventing twisting of the lever about the major axis of the slot to obviate wedging of the lever in the slotted plate 14. On rotating the lever 11 about the shaft 24, the hub portion 23 acts on a push-pull cable 26 to condition the change-speed transmission for automatic operation under the influence of vehicle speed or engine manifold depression. The hub 58 and sleeve (65) may be vulcanized with high quality rubber to ensure permanent attachment thereof to the bushing. Holes 44a, 44b provide alternative mounting positions for the push-pull cable 26. The lever 11 is formed with an elbow, Fig. 5 (not shown), to ensure biasing thereof towards the stepped side of the plate 14 at all times. A safety switch 72 (not further described), prevents starting of the engine unless lever 11 is in neutral. In position (11-1), the transmission is in neutral; in (11-2) in reverse; in (11-3) automatic shifts from low through two intermediate ratios to top are provided; in (11-4) top is omitted; in (11-5) an automatic shift from low to the lower of the two intermediate ratios is provided; and in (11-6) an automatic shift from a sub-creeper to a creeper ratio below low is provided.
Patent DE-1801087-A1 (DE)
Title: Heat transfer system with forced air circulation
Inventor: MARTINEZ CARLOS BENJUMEDA
IPC: F24H3/08
Filed: 1968-10-01
Abstract: Hot air arising from a combustion zone where heat can be produced by a wide variety of energy carriers gives up its heat to the exchanger by means of a system of channels in accordance with the chimney draught or suction effect which imparts a flow acceleration to the air sufficient to raise its velocity to the required extent for efficient heat transfer. The air channels form a vertical array connected to top and bottom headers and with centrally embedded pipes. No auxiliary equipment is necessary.

Patent DE-2019031-A1 (DE)
Title: Zip fastener machine
IPC: B29D5/04
Filed: 1970-04-21
Abstract: The machine works from monofil plastics which come in as strand material for placement between the teeth provided on a forming member. The strands are fed in by a feeder and below this a pusher whose push track is curved, arcuate and matched by the opposed curved or arched surface of a surmounted feeder. The feeder surface protrudes to form embossing cams at intervals so as to stamp out the coupling surfaces on the strand which is thus fed on positively into the tooth space with the legs superposed and the rear connectors of the links grasping the divider teeth from behind. A finger on the pusher can be used to hold the connectors down during placement and a lever is used to drive the links down in between the teeth. Any thickness of strand can be handled owing to the positive feed between feeder and pusher.

Title: Rubbish comminuter with toothed drum - has pivot arm, cooperating with counter-comb and sieve jacket
Inventor: SCHERER ALBRECHT
IPC: B02C23/04
Filed: 1973-09-07
Abstract: Comminuter for preparing rubbish has a revolving milling tool consisting of a slowly revolving drum set with tearing teeth, turning away over a counter-comb and sieve jacket, and mounted on a spring-loaded pivot arm. Comminution results of bulk material between the drum and in a hopper above it, and between drum and comb and drum and jacket. Preferably the drum escapes upward, owing to the pivot arm, when hard material is clamped between it and the comb or jacket. Comminution is uniform, and wear on the tools is small. Should hard material become jammed between the drum and counter comb or sieve jacket the drum, by virtue of its fixture on the swinging arm, disengages by moving upwards, "climbs", as it were, over the destruction and damage to the apparatus is prevented.
