Title: Semiconductor chip assembly using automatic process - has substrate disc absorbing water cut by diamond blade saw and using thermoplastic lacquer
Inventor: PELTZ HANNS-HEINZ
IPC: H01L21/78
Filed: 1976-11-24
Abstract: The semiconductor chip assembly uses a semi-automatic process for mounting the chips on a support. Instead of the relatively expensive aluminium coated substrate, the process uses a substrate disc which absorbs a small amount of water and which can be cut with a diamond saw without damaging or causing a lot of wear to the blade. A good adhesive strength is achieved with the adhesive used. There is a high degree of dimensional stability, heat resistance and resistance against acetone and alcohol. The coefficient of thermal conductivity will balance out any thermal stresses. The substrate disc is made from separate foils of hard paper and the adhesive is a thermoplastic lacquer.

Title: Dual heat exchanger thermal power unit - is driven by medium heated to expand in one heat exchanger and cooled by latent heat of fusion in other one
Inventor: HOLZER WALTER
IPC: F01K3/10
Filed: 1977-01-18
Abstract: The thermal power unit is driven by the exchange of heat between two or more heat exchangers (1, 8). The first exchanger (1) stores latent energy e.g. in the form of latent heat of fusion of a solid which turns into liquid when heat is supplied. The second exchanger (8) receives heat from its surroundings. The two exchangers are connected by a closed cycle (2, 7, 3, 7) carrying a medium to transfer the heat, which medium expands and drives a turbine or rotary pump (4) to produce mechanical energy and to return (5) the medium, after it has been cooled, to the second exchanger (8). The second exchanger may receive heat from a latent-heat store in which e.g. a liquid solidifies whilst giving up its latent heat.

Title: Electronic heater control circuit - has saw tooth generator connected as quasi-feedback to electronic control circuit
Inventor: KIESLICH HORST
IPC: G05D23/24
Filed: 1977-06-25
Abstract: The temp. dependent control circuit is for the heating medium feed- and return room temp. and for the heating energy. A separate saw-tooth generator with adjustable pulse width, is connected as a constant quasi-return to an electronic temp. dependent heater control circuit. The heater control circuit consists of a Wheatstone bridge with an external temp. dependent resistance; and of an operation amplifier with three-point characteristics. The resulting impulse width-proportional control voltage actuates a servo unit via switch elements. The generator has a field effect transistor (11a), with two variable resistances (8a, b) and a capacitor (10). This permits the periodic length of the servo tooth impulses to be adjusted between one second and thirty minutes. The amplitude of the impulses is limited by a diode.

Title: Low drag marine propulsion system - has laminar flow water intakes in bows above which are air intake scoops with air discharged into ducts at stern by impellers
Inventor: MAYR MAX
IPC: B63H11/04
Filed: 1977-06-29
Abstract: The high speed, low drag marine propulsion system has laminar flow water intakes on both sides of the hull at the bows, the water being expelled from stern ducts after passing through thrusters. Air is collected in scoops over the bows and from the windward side of the boat and expelled from ducts at the stern.

Title: Failsafe clamp for tow-rope - has friction clamp and spring plunger which disengage under set strain and pay out more cable
Inventor: ADLEYBA CIHAT
IPC: B60D1/18
Filed: 1977-11-19
Abstract: The two rope is fitted with a spring loaded clamp (14) which couples to the towing cable by a friction clamp and with a spring loaded plunger (5) to control the action of the clamp. As the tension applied to the tow the spring is compressed and the clamp relaxes. Peak tension is accommodated by the system without transmitting the forces to the vehicle towing points. The clamp operates under peak tension and on sudden release of tow, as during braking. It provides a safety force to completely release the two rather than cause damage. The release point can be set for heavy or light vehicles.
