Title: Fresh air control for car - with linked sliding controls for fresh air flaps and blower rheostat on dashboard
Inventor: BOEVING EGON
IPC: B60H1/00
Filed: 1973-07-11
Abstract: The fresh air flow for the car is controlled by one lever whose position along a slot determines the amount of fresh air added to the system. The lever alters the setting of a rheostat progressively after the linked fresh air flap lever has been set to its maximum. In this way the blower is only activated after the maximum effect has been obtained from the flaps. The driver can then readily adjust the flow without looking at the controls. For recirculating air, in winter etc. the control is pulled axially to set the blower to maximum.

Title: Cutting tool with reduced vibration - hard outer cutting soft inner support section and transition section
Inventor: CLINE CARL F
IPC: B23B27/14
Filed: 1974-02-13
Abstract: The composite cutting tool for machine tools has an outer cutting section of hard elastic material which acts on the workpiece and an inner support section of a softer, resilient material, with an intermediate transition section, of a medium hard material for mechanical damping. This transition material has a greater mechanical damping property than the inner support section, but a smaller mechanical damping property than the outer cutting section. The outer cutting section so covers the transition section that contact with the workpiece is prevented. Preferably the support section is of metal and the two other sections are of a metal-ceramics mixture.

Title: Backfill concrete production and placement - ring chamber blower mixes aggregates with binder for blowing into cavity
Inventor: HOELTER HEINZ
IPC: E21D11/10
Filed: 1974-03-02
Abstract: Manufacture and placement of concrete for backfilling purposes in large cavities in mining operations, e.g. between supports and rock in headings to prevent gas accumulations is achieved by the use of pressurised suction nozzles of the ring chamber blower type. These draw in aggregates which are then wetted with liquid binders in the expanded compressed air jet and can be blown into the waiting cavity in this condition. The system eliminates the use of hand operated machines to a large extent, thus avoiding a labour intensive operation.
