Title: IC engine fuel injection system - has switch closed by throttle when idling in transistor base current circuit
Inventor: SCHUELZKE PETER DIPL ING
IPC: F02D41/08
Filed: 1974-10-23
Abstract: Duration of opening of one or more solenoid-operated injectors is regulated by a monostable multivibrator, the duration of whose impulses depends on one or more engine parameters, particularly the vacuum downstream of the throttle. An extension stage delivers an impulse added onto that from the multivibrator and whose length depends on that from the latter. The mixture is enriched during warming up. An idling switch is coupled to the throttle butterfly or the accelerator pedal, and is closed in the idling position. This switch is in the base current circuit of a first transistor whose collector is connected via a resistance and a diode to the emitter of a second transistor functioning as an emitter follower.

Title: Induction motor with output shaft rotating at supersynchronous speed - using rotor surface as part of step up gear uses friction prive to output
Inventor: VOLKRODT WOLFGANG DR ING
IPC: H02K1/16
Filed: 1974-10-29
Abstract: The application is particularly to small motors running at very high speeds, for example (20,000 rev/min. driving a vacuum cleaner fan. In order to eliminate the undesirable features of the universal motor an induction motor is employed. One slot (7) in the stator is not wound, and is used to carry the output shaft (12) which is held in suitable bearings on the motor frame. Through the slot opening the shaft is brought into mechanical contact with the smooth surface of the rotor (3) thus producing a friction drive step up gear. The shaft may be suitably treated to provide a high coefficient of friction on its surface. The stator (1) is typically designed with a ring winding (2).

Title: Baby's bib fabric mfg. process - uses layered fabrics of thermoplastic film with fabric cladding for thermal pressure bonding
Inventor: VANHOVE JAQUES
IPC: A41B13/10
Filed: 1975-01-11
Abstract: A process is claimed for the manufacture of multilayered material which is absorbent but at the same time impermeable for applications such as babies bibs. A stack is formed by placing materials on top of each other, each material being composed of three layers with a thermoplastic film core surrounded by non thermoplastic materials. Heat and pressure are applied to the stack so that the thermoplastic cores are bonded to the layers on either side of them at the points of heat and pressure contact. The process gives a dense impermeable material with good absorbent qualities, economic manufacturing costs.

Title: Stacked sheet separator mechanism - has bar sliding vertically with flexible separator member bearing against top sheet
Inventor: KJELLMAN LARS HARRY WILHELM
IPC: B65H3/56
Filed: 1975-02-15
Abstract: The mechanism is particularly for handling sheets of plastics, separating the top one from those below it. A bar is movable up and down parallel to the stack, and carries a separator member, which in the neutral position extends parallel to and above the topmost sheet. As the latter is lifted clear, this member bends, and slides over the endge to between this sheet and the next one underneath it. Th member can be in the form of one or more leaf springs; in the latter case one above the other and extending for unequal distances above the topmost sheet, so that they slide over its edge in succession. The bar can be arranged to slide downwards freely under gravity, although a locking device prevents it moving upwards.

Title: Sawtooth current generator for deflection coil - has thyristor connected across coil and controlled from series commutating inductor
Inventor: BE GMANN GUSTL DIPL ING
IPC: H03K4/83
Filed: 1975-05-30
Abstract: The sawtooth current generator, for a deflection coil, has a sweep switch consisting of a thyristor (7) and anti- parallel diode (8) connected via a supply capacitor across the deflection coil (9). The coil is connected in series with two further capacitors (4, 6), a commutating inductor (3) and an input inductor (1) across the supply poles. The control pulses for the sweep thyristor are obtained from the commutating inductor via a rectifier (11) and RLC circuit. The first peak from the commutating inductor charges a parallel capacitor (12) which discharges into a capacitor (14) in the RLC circuit. This latter capacitor discharges through a shunt resistor (19) and causes the appropriately poled pulses to be applied to the thyristor.

Title: Vacuum circuit breaker drive system - uses additional spring to give bias to system when opening and closing
Inventor: KUMAGAI TATEO DIPL ING
IPC: H01H9/00
Filed: 1975-08-02
Abstract: The object is to assist in eliminating timing discrepancies in multiple pole circuit breakers, especially if they are of the vacuum type, caused by friction. The problem is overcome by providing an additional spring which opposes the action of the spring controlling the operating cam when the switch is closing and assists it when opening. The additional spring is separately anchored at one end and coupled to the operating rod at the other. It is biased such that when the cam disc driving spring is acting to close their actions are opposed, but when opening their effects add: The extra spring is always tending to open the contacts of the vacuum switch.
