Title: Magnetic recording material with binder cured by ionising radiation - allows coating with solvent-free paste, giving resistance to solvent and scratching
Inventor: DIECK LEOPOLD DIPL PHYS DR
IPC: G11B5/702
Filed: 1980-02-21
Abstract: Magnetic recording material consists of a carrier (I) with a magnetic coating having a plastics binder (II) crosslinked by ionising radiation. Pref. (II) is an acrylate prepolymer and (I) is a polyester film, which pref. contains unsaturation before irradiation and is (partly) crosslinked with (II) after irradiation. The coating is applied in the form of a paste of liquid, solvent- free polymers, prepolymers and/or monomers polymerised and/or crosslinked by radiation as (II) and (III), esp. gamma-Fe3O4 (IIIA) or CrO2. (II) pref. is an epoxy, polyester and/or polyurethane acrylate. The amts. used are 20-30 (wt.)% (II) and 70-80% (III). The coating is applied in a thickness of 2-5 micron and polymerised and/or crosslinked under normal atmos. conditions by irradiation with electrons, pref. with energies of 140-250 (150) keV. It can be tempered after and/or pref. before irradiation for 1 min. to 3 hr. at 40-200 deg.C (2 min. at 150 deg.C before and 1 min. at 150 deg.C after irradiation) and then irradiated again. The coated (I) is passed through a radially symmetrical magnetic field before irradiation. The paste pref. is applied to the back of the film and passed over a highly polished drum, where it is irradiated with accelerated electrons to effect crosslinking. The magnetic coating is insensitive to solvents and resistant to scratching and can be made from a mixt. of magnetic particles (III) and (II), without a foreign solvent.
Patent DE-3009211-A1 (DE)
Inventor: HEPP VOLKER PROF DR
IPC: G04G99/00
Filed: 1980-03-11
Abstract: An event-module is, on its lowest logical level, a universal instrument for measurement and storage of times, intervals, periods, time series and durations. It permits codification of personal and external events by means of time-marks and makes them accessible in the course of their realization. It permits the possibility of analyzing the serial structure and the correlation in time of these events in a most general way. The evolution of the present can instantaneously be compared with the anticipation of the future by use of external time-marks. Further, the introduction of a programmable dialog-logic which enables the user to find answers to specific questions of, e.g., his personal experiences is disclosed. The module helps in decisions and is not only a measurement device, but also a partner. Likewise, the module can act as an opponent of the user and e.g. sophisticated games may be played. The event-module can be considered a cybernetic system into which the human being is incorporated in contrast to conventional learning machines (TURING machine, chess computer) and which interacts with his behavior patterns (habits, orderliness, etc.). This system not only records events and their duration and displays them on demand, but it interferes due to its boundary conditions (Te,  DELTA Te) with the actual course of events. It is a mobile, interactive system with learning potential.
Patent DE-3012771-A1 (DE)
Inventor: WILLEMS LEONARDUS FRANCISCUS
IPC: G10L25/90
Filed: 1980-04-02
Abstract: In a formant speech analysis synthesis system, formant extraction to control a recursive digital all-pole filter encounters the problem that pole-pairs are not orderly arranged and that real poles may occur which are not representative of formants. The problem is solved by transforming the coefficients of the second-order sections of the filter to coefficients which can be easily ordered and by means of which it is simple to assign formants to the real poles.

Title: Coolant feed for pillar drill - has spindle hand lever moving sprung piston to pump coolant via adjustable tube
IPC: B23Q11/10
Filed: 1980-04-30

Title: Mfg. crystalline silicon plate or strip with columnar structure - suitable for making large solar cell, by sintering on sheet of high m. pt. metal
Inventor: HANKE LEOPOLD DR PHIL
IPC: C30B29/64
Filed: 1980-05-09
Abstract: Prodn. involves making a slip from Si powder with a particle size of under 1 micron and a binder, spreading the slip on a substrate and drying the sheet formed, then removing the substrate and sintering the sheet below 1400 deg.C on an inert, refractory substrate in a protective gas atmos., until a layer of monocrystalline granules of dia. corresp. to the thickness of the sheet is obtd., as in 2927086. The novel feature is that the sintering substrate is a sheet of high-melting metal, which is resistant to Si, pref. a sheet of W or Ta. The substrate can be used many times, since there is no change in form or reaction with Si, and the sintered material is not contaminated by diffusion of material from the substrate.

Title: Box-section frame equipment - has walls doubled by folding sheet metal strip and supported by coupling pieces
Inventor: SMITKA GUENTER
IPC: A47B47/00
Filed: 1980-09-03
Abstract: The equipment forms a box-section frame for an air-conditioning unit etc, having profiled bars along the edges securing walls and coupled together by corner pieces with clamping pieces inserted in their ends. The bars are formed from sheet-metal bent into troughs with two outside long walls at right angles to each other, each joining onto a second short wall bent inwards at right angles. Third and fourth walls join onto the second ones, the third ones extending towards each other and ending clear of each other to form the trough mouth. The fourth walls form strips against which the unit walls bear and run parallel to the first walls, and all walls are symmetrical in relation to the line bisecting the angle between the first ones. The third walls (5) are doubled, by folding of the sheet-metal strip, and are supported in place by the clamping coupling pieces (10-14).

Title: Hotplate for cooker with insulating layer - fixed between heating element and bottom of shallow pot-shaped holder
Inventor: KUMMERMEHR HANS
IPC: H05B3/74
Filed: 1980-09-12
Abstract: A thermal insulator (9) is pressed against the bottom (4) of the shallow pot-shaped holder (1) that contains the heating element. The insulator is made of an aerogel oxide, esp. a silicic acid aerogel, made by flame pyrolysis and reinforced with mineral fibres and/or containing an opacifier. The insulator has fine pores. The insulating layer (9) is convex on its surface facing the bottom of the holder so that when the force used to press it into the holder is removed the layer does not bow up outwards at its centre. The layer may also, or alternatively, be concave on its surface facing away from the bottom of the holder. The bottom of the holder may also, or alternatively, have devices to retain the insulating layer. Such devices may be perforations whose holes slope at an angle to the surface of the bottom or indentations, likewise included. The insulating layer may also be bonded to the bottom of the holder by an adhesive. The advantage lies in the simple manner in which the insulating layer is prevented from bowing outwards.

Title: Hydraulic ram synchronising equipment - has movement-reversing ram connected to opposite sides of main rams
Inventor: DROTLEFF ZOLTAN
IPC: F15B11/22
Filed: 1980-12-18
Abstract: The equipment synchronises hydraulic rams in an open circuit, there being two or more double-acting rams connected in series and having the same bore, piston diameter and stroke.

Abstract: The invention relates to a folding bicycle with a frame, at least one steerable front wheel, associated front-wheel fork and handlebars, at least one driven rear wheel, associated rear-wheel fork and chain drive with pedal cranks as well as with saddle pillar and saddle. So that the bicycle is not a bulky object when folded together and can be easily transported, for example even on public transport, the frame is a case-like housing (1) on which the front-wheel fork (20), optionally the handlebars (23, 24), the saddle pillar (14) and the rear-wheel fork (11) are pivotably mounted such that the bicycle, with the parts pivoted in or folded in, can be transported like a case. The housing (1) can be essentially box-shaped and hence case-shaped, the required openings being closable by flaps (16 and 28 respectively). The chain drive with bottom-bracket bearing (3), chain wheels (4) and chain (6) is fixedly mounted in the housing, the rear-wheel fork (11) being mounted such that it can pivot about the axis of a drive pinion (7) and there being coupled to this drive pinion (7) a further pinion for a chain drive which extends along the rear-wheel flap (11) and is intended for driving the rear wheel (10) so that on pivoting in the parts the chain tension is not changed. <IMAGE>
