Patent DE-2601351-A1 (DE)
Title: Small or irregular transmission line signal suppression - uses logic network with double threshold and symmetry detection
Inventor: AFFOLTER PETER DR
IPC: G01R19/17
Filed: 1976-01-15
Abstract: A method of suppressing small or irregular shaped transmission line signals, detecting in particular packages of symmetricall pulses in certain transmission lines suppresses the noise even if it exceeds a specified threshold. A packet or sequence of regular symmetrical positive and negative roughly sinusoidal pulses of more than a given amplitude is detected, and any other signals suppressed by finding the signal to two input flip flops via Schmitt trigger circuits set to give two distinct sets of positive and negative thresholds. The outputs of these flip flops feed two more flip flops in a cross connected configuration and the outputs of these are fed to an AND gate from which the circuit output is taken. A hysteresis characteristic is produced which suppresses small or irregular waveforms as required.

Title: Fastener for temporary fixing brush head to handle - uses rotary cam to force parallel cranked handle prongs apart to engage brush head holes
Inventor: WEIHRAUCH GEORG
IPC: B25G3/34
Filed: 1976-03-19
Abstract: The fastener may be used in the demountable fixing of a brush head onto a handle. A two pronged terminal is provided at the base of the handle, and various fastener mechanisms may be used to displace the prongs into the brush head holes. The prongs may terminate in short square returns. The returns either converge or diverge, and the prongs are displaced in the direction of the returns to engage brush head sockets. The fastener mechanism may utilise a rotating cam or a sliding cursor to effect the desired relative displacement of the prongs.

Title: Olefin sulphonate bleaching with hydrogen peroxide - using aq. soln. activated by phosphate and or silicate
Inventor: YAMAMOTO KAZUO
IPC: C07C301/00
Filed: 1976-05-18
Abstract: Bleaching of 12-22 C olefin sulphonates takes place by mixing them with >0.1 (0.5-5) wt. % H2O2 and with >0.1(2-7) wt. % phosphate, and/or silicate and heating total to 30-130 (50-100) degrees C, pref. in aq. soln. having pH >5 (7-12). Phosphates and/or silicates act catalytically in controlling H2O2 decompsn. Bleaching activity with H2O2 is improved, nearing that obtd. with hypochlorites. Foaming during bleaching is controlled by using phosphates. Corrosion-resistance of plant can be improved by using silicates. Use of phosphates and silicates achieves foam-control and improved corrosion-resistance of plant.

Title: Microscope photometer double beam analysis appts. - has chopper and comparator mirror between specimen and detector
Inventor: DIETRICH ROLF
IPC: G02B21/00
Filed: 1976-06-25
Abstract: The microscope photometer is suitable for reflection and transmission measurements using the twin beam method for qualitative and quantitative analysis of chemical, biological and medical specimens.

The beam is bent by a trapezium prism (6) and enters one half of an object lens (7) which focusses it onto the specimen. The reflected light is then refocussed onto a photo-multiplier detector. To simulate twin beam operation, a chopper mirror is interposed between the sample and the oject lens together with a comparator mirror either between the chopper and the lens or actually attached to the front of the lens.

Title: Volley ball shield for hand and forearm - has triangular section rigid material strapped to forearm with foam layer between
Inventor: MONHOFF KARLHEINZ
IPC: A63B60/40
Filed: 1976-09-16
Abstract: The shield (1) for the hand and forearm for playing volleyball consists of a tube of triangular cross section made of PVC, wood metal or similar material. A strap (2) fixed to the mid-points of two sides of the triangle forms a handgrip at one end of the tube. The other end of the tube is lined with a strip (3) of foam rubber to fit closely around the user's arm. The shield enables the user to strike the ball with much greater force and to control its direction more accurately than is the case when using bare hands. An alternative design uses a woven net mounted on a frame instead of a triangular tube.

Title: Appts. for folding and welding continuous thermoplastic sheet - into narrow pockets, with longitudinally aligned filling tubes to keep the pockets open
Inventor: PAULY HANS
IPC: B65B9/20
Filed: 1977-07-04
Abstract: Continuous thermoplastic sheet is converted into small individual sealed bags by passing through a guide which folds both edges of the sheet to the centre of one face of the sheet prior to continuous longitudinal welding below the level of formation of the longitudinal and the transverse welds. Filling tubes parallel to the sheet axis discharge into each of the twin pockets below the level of longitudinal welding, but above the level of transverse welding. Used for mfr. of rectangular sachets or packs filled with e.g. liquid, creamed or paste materials such as foodstuffs. Narrow pockets can be made and filled more readily by longitudinal division and filling than by conventional transverse division and filling because the filling tubes are static and keep the faces of the advancing film continuously apart.
