Title: Bonding steels of different compsns. by heat and pressure - using flame spray applied nickel brazing alloy contg. chromium, boron and silicon
Inventor: PRZYBYLLA FRITZ ING GRAD
IPC: B23K35/30
Filed: 1978-02-08
Abstract: Prior to bonding, the joint surfaces of the workpieces are coated with a metal layer (a) which is a commerciallyavailable Ni-Cr-B-Si alloy powder applied by flame spraying to obtain a layer (a) 0.2-1.0mm thick, followed by sintering. The workpieces are then heated on their joint surface to 900-1080 degrees C. and pressed together at 50-500 bars; the pressure is maintained at least until the Ni-Cr-B-Si alloy (a) has solidified. A simple process, where the steel workpieces being joined together may vary widely in compsn. A relatively thick layer (a) can be used to provide accurate final dimensions on the brazed assembly.

Title: Ground air sampling equipment - has free space in incompletely-filled interchangeable sample containers filled with inert gas
Inventor: RADTKE MANFRED
IPC: G01N1/22
Filed: 1978-02-20
Abstract: Ground air sampling equipment has a fixed sample container without a gas chamber for intermediate storage of an exchange gas. Two identical quickly interchangeable sample containers are used, and a gas chamber for intermediate storage of an inert gas is combined with the containers to form a unit. Sampling using the equipment is much faster than with existing equipment, e.g. 20-25 measurements per hour as opposed to 20 per day. Thin channels are used for both the sensor and pump unit, i.e. having a dia. of 1 to 2mm at most. The turbulence is therefore limited so that a mixing of the specimen medium with the still volume of gas does not affect the specimen taken.
Patent DE-2812166-A1 (DE)
Inventor: BIGLER HANS
IPC: H05B6/06
Filed: 1978-03-20
Abstract: In this method, undesired side effects, e.g. an excessively high starting current inrush or remanent magnetisation, are eliminated by switching the heating current on and off in a surge-free manner. A workpiece is inserted as a secondary short-circuited turn (3) into the separable iron core (1) of a primary field coil (2), and not only is inductively heated there but is also immediately demagnetised again by appropriate phase-gating control of the field current. An RC circuit (8, 9, 10) has the effect that switching on and off the heating time-delay switch (7) is passed on only gradually to the integrated circuit (6) and the triac (5) for controlling the excitation. <IMAGE>

Title: Road surface traffic sign arrow - has outline surround of different pref. lighter colour than body of arrow
Inventor: SCHMUCK PETER
IPC: E01F9/50
Filed: 1978-09-30
Abstract: The arrow is used to indicate correct traffic flow directions, reduction in number of lanes or for other driver guidance. The arrow marking system is typically applied to road carriageway surfaces, with a single-colour marking area.

Title: Time division duplex data receiver synchronisation - suppressing data transmission to allow echoes to decay before synchronising
Inventor: PFEIL DIRSKO VON ING GRAD
IPC: H04L5/14
Filed: 1979-04-30
Abstract: Digital signals are exchanged over a 2-wire subscriber's line by time division duplex. Signals are sent in blocks of 2 sync. bits and 18 data bits at 256kBit/s at intervals of 250 microsec. On receiving a block from the exchange, the subscriber sends his block back after a pause of 20 microsec. Until initial synchronisation of the exchange receiver is achieved, data transmission from the exchange is suppressed and only sync. bits are sent. The exchange receiver is then synchronised to the first bits received from the subscriber. This allows 70 microsec for echos to die away and ensures that the exchange receiver does not synchronise to echos of its own transmission.

Patent DE-2932737-A1 (DE)
Inventor: BEHNKE JOACHIM DIPL ING DR
IPC: C08G63/66
Filed: 1979-08-13
Abstract: A method for production of polycarbonate-polyether-blockcopolymers is provided. One or more solutions comprising bisphenol A and polyalkyleneglycol and a phosgene solution are added to a cooled initial reaction medium in a cooled reaction chamber in such a way that the phosgene contacts substantially the reaction partners from the one or more cooled solutions after they have spread in the reaction medium. Preferably the phosgene solution and the one or more solutions are added through tubes ending above the liquid level of the reaction medium such that the solutions added contact only within the stirred reaction mixture the reaction partner. The phosgene is employed in an excess of less than about 10 weight percent of the stochiometrically required weight amount relative to bisphenol A and polyalkyleneglycol. The polymer is useful in the production of membranes for dialysis, ultrafiltration and reverse osmosis.
