Patent DE-2523421-A1 (DE)
Title: Manual printer with embossed card printing forms - has upper and lower pressure rolls
Inventor: TITMUSS KENNETH WILLIAM
IPC: B41L19/00
Filed: 1975-05-27
Abstract: The printer is especially for printing from credit cards. It has an upper and a lower casing part (1,2) assembled for an opening (12) in the upper part to provide access for a card carrier to a pair fo upper and lower pressure rolls (7, 7A) mounted on the respective casing parts so that printing is effected when the carrier is fed into the nip of the rolls together with the card, a sheet of carbon paper and a sheet of print paper. Two sets of rolls (7, 7A, 5, 5A) may be provided to print lateral parts of the card in succession so as to reduce the force necessary to pass the carrier through the printer.

Title: Storage-stable, aluminosilicate-bonded enzymes - useful in washing compsns to remove albuminous stains from textiles
Inventor: SMOLKA HEINZ DIPL CHEM DR
IPC: C11D3/386
Filed: 1975-07-17
Abstract: An enzyme prepn. consists of an enzyme bonded to a finely divided, water-insol. cpd. disposed to bond Ca and pref. contg. bonded water which is of formula (I) (Katz/nO)x.Me2O3.(SiO2)y (where Kat is an n-valent cation exchangeable with Ca, x is 0.7-1.5, Me is B or Al and y is 0.8-6, pref. 1.3-4) and which has a Ca-bonding capacity of >=50 mg CaO/g. The enzyme prepn. is added to textile-washing compsns. where ir aids the removal of albuminous stains. By bonding the enzyme directly to a carrier, problems associated with previous attempts to add granules of the enzymes to washing compsns. (i.e. unwanted granulation aiding salts) are avoided.

Title: Sun and planet gearing with load equalization - has kinematic chain of links between planets and planet carrier
Inventor: VATTEROTT KARL-HEINZ DIPL ING
IPC: F16H1/22
Filed: 1975-07-24
Abstract: Sun and planet gearing includes a kinematic chain of elements (22) connected between the planet wheels (23) and the planet carrier to equalize the loads on the planet wheels. Mathematical formulae are given for optimizing the number of links and the number of planet wheels. The parent specification described a kinematic chain of a closed rotational system unsupported by fixed structure. The present addition provides for such support for the rotational input and output vectors of the chain, i.e. for the input and output shafts of the gearing.

Title: Cancer cell decomposition system - applying irradiated cancer cells to inflamed skin area to produce antigens
Inventor: HANSCHMANN HORST
IPC: A61M37/00
Filed: 1975-08-04
Abstract: Radiation-damaged viruses, or their carbon mutations, or information chains with bonding flaws, or cancer cells which have been altered by ionising radiation are impregnated with a foreign substance by means of the blue light spectrum, solar radiation or minute fluorescing particles such as luciferin to form antigens in a small surface inflammation in the skin. The tissue sample of cancerous cells is emulsified with luciferin in an ultrasonicator and applied to a small inflamed area of the skin and the resulting antigens used to break down similar viruses, cells or mutant information chains in the body. Initially ultrasonic or hypersonic oscillations or radiological treatment can be used to break up the majority of the cancerous cells in the tumour.

Title: Hot water tank return flow heat loss preventer - includes heat trap at bypass line connected to supply
Inventor: BITTER HARALD DIPL ING DR
IPC: F24H9/12
Filed: 1976-04-08
Abstract: A hot water circulation system includes a hot water tank (4) or other unit in which the hot water enters at the top (8) after passing through a three way valve (2) connected to the supply (1). This valve can be used to shut off the supply to the tank, but allow the hot water to continue along a by pass line (5) to a further part of the circuit. There is also a connection between this line and the bottom of the tank through which a heat loss can occur. To prevent this, this connection can be a bend which forms a trap to prevent heat from the by pass from flowing into the tank. Alternatively an upper fin and a lower fin can be spaced apart inside the connecting tube (7) to form a trap.
Patent DE-2619237-A1 (DE)
Title: Noise generator to mask cable TV signals - prevents reception by unauthorised subscribers by varying attenuation of signal
Inventor: HANFGARN WERNER DIPL ING
IPC: H04N7/171
Filed: 1976-04-30
Abstract: The noise generator masks specific cable TV signals to prevent reception by unauthorized subscribers. This is achieved by continuously varying the attenuation of the signals. The attenuation is frequency so that only certain programmes are affected. The attenuation may be periodic with a frequency between 50 Hz and the line frequency, and the ratio of the time for which the signal is attenuated to the time of a complete period may be equal to or less than 1:2. The attenuating circuit is switched off by an address signal specific to a subscriber and transmitted via the cable to a special address detector at the receiver. The address signal may be a TDM digital signal.

Title: Oscillating vane motor for use with pressurised gas - has external crank linked to vane through connecting rod and timed disc valves
Inventor: SONCIN EGIDIO
IPC: F01C21/18
Filed: 1976-06-02
Abstract: The engine for the conversion of gas press. to rotational energy produces the pressure by internal combustion. This takes place in a cylindrical casing with four inward-pointing radial ribs, which a co-axial cylindrical piston with four radial vanes divides into eight variable volume chambers. Rotary sleeve inlet and transfer valves and the associated porting are embodie in two opposed ribs; the other two have combustion chambers and spark plug holes. Exhaust is via radial ports 180 deg. apart in the piston hub into the hollow engine centre. From an arm on an axial hub-extension a connecting rod runs to the crank on an external output and timing gear shaft, the whole being so arranged that piston oscillation produces shaft rotation.

Title: Attachment socket for car safety belt - has internal light source which is permanently on enabling user to locate belt end fitting
Inventor: FREY EGON
IPC: B60Q3/02
Filed: 1976-08-31
Abstract: The attachment socket (1) for a car safety belt is provided with a funnel-like recess (3) to receive the end fitting of the belt.

Title: Amplitude modulation to phase modulation conversion factor - is measured for test object using amplitude modulator and phase discriminator
Inventor: MUEHLBERGER WALTER ING GRAD
IPC: G01R29/06
Filed: 1976-09-29
Abstract: An amplitude modulated A.C. voltage is applied to the tested object. The phase modulation produced in it is converted by a following phase discriminator in a corresponding change of output voltage, which serves as a measure for the am/pm conversion factor. The measurement a.c. voltage (Um) is amplitude modulated by a modulation a.c. voltage (Us), in turn modulated with an auxiliary A.C. voltage (UH). A voltage component (Us") of the frequency (fm) demodulated after passage through the object (X) is applied to a phase discriminator, to which a reference A.C. voltage (UB) of the same frequency (fs) is applied. Its output voltage variations at a frequency (fH) of the auxiliary output voltage (UH) are evaluated.
