Title: Twin-piston two-stroke combustion engine - has common compression chamber and crank case, pistons acting as pumps
Inventor: MIEHLKE WERNER
IPC: F02B75/02
Filed: 1973-09-22
Abstract: The two engine cylinders are arranged in parallel and contain reciprocating pistons between the tops of which there is the common combustion chamber. The lower ends of the pistons act as charging pumps in connection with the common crank case.

The second piston draws in an air-fuel mixture, pre-compresses this and transfers this to the second inlet ports in the combustion chamber. The pistons may, alternatively, act as separate charging pumps, each being associated with a separate crank case, one piston pre-compressing fresh air and the other an air-fuel mixture.

Title: Wound cylinders from reinforced plastics rovings - pressed to shape by sliding tools on winding mandrel before hardening
Inventor: KRAEMER REINER
IPC: G02B5/12
Filed: 1973-10-12
Abstract: Wound cylindrical parts for use as bearing bushes, spring rings, insulators etc. are produced by wrapping glass-fibre reinforced polyester plastic rovings around a mandrel.

Title: Semiconductor chip support prodn. - uses solder blobs applied via templates or by screen printing using appropriate solder paste
Inventor: STEIN KARL-ULRICH DR ING
IPC: H05K3/34
Filed: 1974-03-28
Abstract: The printed circuit board with a semiconductor chip is contacted, together with the semiconductor chip contact points by depositing solder blobs on the conducting paths of the circuit board and on the semiconductor chip contact points. The tinned contact points are placed on top of each other and the soldered together. The solder blobs are applied through a template or by screen printing using a soldering paste. The contact points of the semiconductor chip are prepared before screen printing by application of a passivating and an adhesive layer. A copper-gold alloy adhesive layer may be applied on the strip aluminium conducting layer, and subsequent etching leaves it only at the contact points, on which the solder is then applied. The paste applied is then heated up to its melting point in a following operation.

Title: Binding inorganic glassy bodies by means of metals - using combination of active and non-active metals
Inventor: SCHMIDT-BRUECKEN HEINRICH DIPL
IPC: C04B37/02
Filed: 1974-04-10
Abstract: Binding together inorganic bodies made from glass, glas-ceramic, ceramic or quartz by means of a combination of an active metal(s) (e.g. Li, Be, Mg, Ti or Zr) or its precurson (e.g. azide) with a non-active metal (e.g. pure Ag, Cu or Au) is effected by applying the metal combination to at least one of the surfaces to be jointed; joining the surfaces under press. and heating in vacuum or a protective atmos. to such a temp. that chemical bonds are formed between atoms of the active metal and components of the inorganic body. The known process of metal-binding, mono- or, at most, bi-component ceramics (such as Al2O3 and/or BeO) termed 'dry-soldering' is adapted to joining glassy mixed-oxide bodies (or bodies contg. glass phases, solid solns. or the like) and glassy quartz. The active metal forms chemical bonds with one or more components of these bodies, whilst the non-active metal is sintered, whereby very strong joints are formed.

Title: Loading vehicle travelling mast - has strips running parallel to casing to damp out oscillation on halting
Inventor: SANDER BERND ING GRAD
IPC: B66F9/07
Filed: 1974-04-20
Abstract: The mast is particularly for forklift trucks and cranes used to handle goods in shelf systems, and has a series of strips running coaxially to its casing on the inside or outside. The strips can be of different lengths, assembled into a leaf-spring-type packet against the mast, all beginning at the base, and ending in steps as they extend upwards. They can be of metal, plastic, or a mixture of the two, with interleaving of a different material between them, their surfaces and that of the interleaving components being ribboned or roughened. The design rapidly damps out any oscillations in the mast on halting after travelling along the shelves etc., and thus greatly assists speed and accuracy of manoeuvre, particularly in automatically-operated warehouses.

Title: Carburettor with electro mechanical metering regulator - has computer to determine fuel air mixture ratio and ignition timing
Inventor: PRAGER GEORG FRIEDRICH RUDOLF
IPC: F02D35/00
Filed: 1974-06-10
Abstract: The circuit is actuated by the ignition switch to feed current to a voltage stabiliser and an oscillator to pass square waves on to a computer and a Lambda transmitter. The electro mechanical actuators fed by the output amplifiers are then ready to supply fuel to the carburettor(s). As soon as the engine is started, engine revolution speed signals are transmitted the engine speed governor and the ignition timing regulator. The ignition contact breakers are advanced and the ignition timing then is taken over by a thyristor unit corresponding to fuel octane engine revolution speed and load. The Lambda transmitter forms from the oscillator signal and the revolution speed signal the corresponding fuel air mixture ratio to be given to the computer which finally determines the correct ratio, after taking into account engine temperature and air pressure, to be transmitted to the fuel regulator units. An electronic lock can be introduced as an anti theft device.
