Title: Integrated circuit with field effect transistors - for memory cell has enhancement and depletion driver and load metal oxide transistors
Inventor: DANGEL JUERGEN DIPL PHYS
IPC: H01L27/088
Filed: 1973-11-12
Abstract: In an integrated circuit with field effect transistors (FETs) with driver transistor(s) (I) and load transistor(s) (II), (I) is a metal oxide semiconductor (MOS) transistor of the enhancement type and (II) a MOS transistor of the depletion type and the circuit is produced by n-channel Si gate technology. The threshold potential of (I) and (II) pref. is regulated by ion implantation, esp. using B ions for (I) and P ions fro (II). The field threshold potential of the parasitic FETs can be increased by ion implantation over the entire surface or a limited part of the surface, pref. using B ions. There pref. is no oxide fil between the poly-Si-layer and the n+ - zone forming the source region of (II) and thus a contact results which contributes to an increase in the packing density. Used in memory cells for data stores produced using the monolithic integrated technique.

Title: Semiconductor laser with beam generated in tunnel zone - can be modulated by very high frequencies with low absorption losses
Inventor: RUSSER PETER DIPL ING DR
IPC: H01S5/062
Filed: 1974-04-30
Abstract: The semiconductor laser generates the light beam in a tunnel zone sandwiched between two layers, and the current flowing through the device flows through one of the layers. it can be modulated by very high modulating frequencies. The output radiation only spreads to the zones bordering active laser zone of the semiconductor substrate. The laser zone is a tunnel zone which is embedded in between two semiconductor layers built up as a waveguide. The losses due to absorption are very low. The regions of the semiconductor immediately around the tunnel zone have a higher refractive index than the outside layers and it acts as a dielectric between two layers of different type conductivity.

Title: Hydraulic piston seal with sealing lip - uses two identical knife edge seals to prevent leak oil losses
Inventor: EDLUND ROY DIPL ING
IPC: F16J15/3208
Filed: 1974-05-16
Abstract: A hydraulic seal arrangement has two identical seal rings placed axially next to one another. Each seal has a seal ring which is in contact with the piston rod by a circular knife edge sealing lip. A pre-stressed O-ring, located in the same groove as the seal ring exerts a radial contraction force on the seal ring. The low pressure side of the seal ring is tapered whilst the high pressure side has a cylindrical recess with the seal lip in between. Any oil that leaks into the circular space between the two seals is carried back into the high pressure chamber when the piston moves in that direction.

Title: Monaural to stereophonic signals convertor - divides frequency band in two or more sections
Inventor: CHRIST HARALD
IPC: H04S5/00
Filed: 1974-05-27
Abstract: Different frequency sections are filtered or divided out from a mono source. These sections are then alternately applied to two or more channels connected to a stereo reproduction system. Unusual effects can be created by leaving out or over-emphasising a section, or allowing a section to be played on both sides or all channels. The function of the loudspeakers can be reversed by means of a stereo potentiometer. In another embodiment the power is taken from the loudspeaker supply of the mono apparatus so that no additional mains or battery supply is necessary. Division of frequencies is made by bridges and potentiometers.

Title: Solenoid actuated mechanical counter - has lever actuated by solenoids which operates on sprocket wheel to move counter display discs
Inventor: VOSSELER MANFRED
IPC: G06M1/10
Filed: 1974-07-01
Abstract: A mechanical counter has activation by solenoid using an impulse signal.

Title: Loudspeaker or headphone automatic level adjustment - surrounding noise is picked up and converted to control electric signal
Inventor: SUEHSMUTH GUENTER ING GRAD
IPC: H03G3/32
Filed: 1974-08-05
Abstract: Loudspeaker etc. is energised, directly or indirectly, by a voltage (UL) obtained by addition of the input signal voltage (US) to a voltage (UP) which is proportional to the production of the incoming signal voltage (US) and a mean value of a rectified voltage (UM) obtained by picking up the back ground noise and converting to electric signal. The microphone (3) is fitted within the the room in the neighbourhood of the window to pick-up the interference coming mostly from traffic. The output (UM) from the microphone amplifier (4) reaches the analogue multiplier (7) via a rectifier (5) and a low pass filter (6) which forms the arithmetical mean value.

Title: Readily soluble dispersions of water soluble polymers - obtd. by polymerisation of oil in water dispersions of monomers
Inventor: SRNA CHRISTIAN DIPL CHEM DR
IPC: C08J3/09
Filed: 1974-12-11
Abstract: Dispersions of water-soluble polymers of mol.wt. exceeding 100,000 in a hydrophilic organic solvent are prepd. by taking an aq. soln. contg. a water-soluble ethylenically unsatd. monomer and polymsg. in a hydrophobic organic dispersion medium in the presence of a water-in-oil emulsifying agent and a polymsn.initiator. Water is removed during the process so that the concn. of polymer is the aq. phase reaches >=70wt.% and then the hydrophobic dispersion medium is replaced by a hydrophilic organic solvent in which the polymer is practically insoluble and which has a b.pt. >100 degrees C. Water-soluble polymers of high mol.wt. dissolve only slowly in water, partic. if in fine powder form, and it may be necessary to remove finer particles by sieving, and dissolve only coarser particles. This wasteful and tedious process is avoided.

Title: Self emptying swarf tray for mechanical saw - has crank driven scraper plate with raking motion
Inventor: RUEZ NORBERT
IPC: B65G25/02
Filed: 1975-06-14
Abstract: The metal mechanical saw is provided with a collecting tray for swarf (4). A scraper strip (6), made from expanded sheet metal, is placed above the inclined swarf tray (4). Two upright arms (11), to which the scraper plate is attached, are linked to two identical crank drives (14).
