Title: Crystallisation of amorphous plastics granulates - by stirring in an upward stream of hot gas
Inventor: NONNENMACHER FRIEDRICH KARL
IPC: B29B13/06
Filed: 1976-04-02
Abstract: Crystallisation of amorphous plastics granulates comprise heating while at rest in a layer of thickness 600 mm., with an upward stream of gas at 140-250 degrees C and with velocity 50-90% of that required to fluidise the bed. When the gas temp. directly over the bed is within 20 degrees C of the inlet temp., the granulate is stirred for 10 mins. and then discharged, opt. with subsequent drying. Used esp. mf or treatment of polar thermoplastics, eg. (co)polyester and polyamides, which tend to agglomerate. Crystallisation is achieved in short and uniform dwell times, with much reduced consumption of hot air and plant size, compared with use of fully fluidised beds with expansion of 100% or more. Prods. have good storage and flow properties.

Filed: 1976-06-03
Abstract: Novels salts of 1,3-bis(-(beta-ethylhexy)-5-amino-5-methyl-hexahydropyrimidine are of formula (I), where n = 1 or 2. X = COOH, OH, NH2, SO3H or SO2NH2 and can be same or different when n = 2. When X = COOH or OH then it must be at the 4 posn.). Hexetidine (II) is known as an antimicrobial, active against bacteria and some fungi, esp. as an antiseptic and antibiotic for the oral mucosa.

Title: Domestic coffee making machine - has electronic circuit to indicate build=up of scale in water heater system
Inventor: EBERTH HELMUT
IPC: A47J31/54
Filed: 1976-07-24
Abstract: A domestic coffee-making machine has a cold water tank (1) with a base (2) provided with two electrodes (3, 3'). The electrodes (3, 3') are connected to a diode (4) which is connected to a warning device (5). The diode (4) is also connected to the contacts of the regulating switch (6) of the water heating circuit. In normal operation all the water flows out of the tank (1) before the heater (7) reaches the temperature at which the regulator (8) opens the switch (6) and so no current can flow between the electrodes (3, 3'). When there is a build-up of scale in the heater (7), the temperature rises more rapidly so that there is some water left in the tank when the switch (6) is opened. This water conducts current across the electrodes (3, 3') which energises the warning device (5).

Title: Dry application of film to substrate - uses heated guide roller with electrode connected to HV HF generator
Inventor: BRINKMANN HORST
IPC: B29C63/48
Filed: 1976-07-28
Abstract: Apparatus for dry application of a web-like or sheet like substrate comprises a film supply roller (13), and a heated guide roller (15). A heat source acting on the surface of the film passing around the guide roller consists of an electrode (18) connected to a h generator (17) supplying a steady current, while the guide roller forms a counter-electrode. The generator and/or the electrode may be retained variably around the film contact zone of the guide roller, and is pref. spaced apart from and radially displaceable relative to the guide roller, to allow regulation of heat intensity and escape of excess heat. The apparatus allows plasticisation of the film without loss of heat, and heating of the guide roller without an auxiliary heat source for the guide roller.

Title: Linear motor disc rotor - is constructed with stiffening webs or slots to compensate for differential thermal expansion
Inventor: BREMER KLAUS ING GRAD
IPC: H02K41/025
Filed: 1976-09-15
Abstract: A motor uses at least one linear motor section to impart motion to a rotor in the form of a disc. The losses generated in those parts of the disc moving at an angle to the travelling field can generate sufficient heat to distort the disc causing rubbing in the air gap and damage to both rotor and armature. To minimise the distortion the rotor, which is made of a solid disc, may be either stiffened or slotted locally to give expansion gaps. The stiffening may take the form of a flanged rim, dished centre, radial ridges or a combination of these. The slotting may be circumferential, radial or a combination or, alternatively, it may consist of a large number of perforations. Air or liquid cooling may be used in the machine.

Title: Magnetic playing figure located on horizontal board - is horizontally and vertically moved by magnetic handle underneath board
Inventor: KOCH FRITZ
IPC: A63H33/26
Filed: 1976-09-29
Abstract: A magnetically neutral playing board (10) is used to move playing figures (18) along a fixed path. The figure (18) consists of a magnetic cube whose polarity axis is perpendicular to the playing board surface. Fixed obstacles (20) are placed across the playing path at certain interval. A handle (14) which is moved along the underside of the playing board includes a bar magnet whose magnetic axis is also perpendicular to the board. The magnetic attraction produced drags the playing figure along the selected path. At an obstacle, a quick upwards movement of the handle produces a lifting of the figure (18), thus the obstacle can be jumped over in a continuous motion.

Title: Rotary recording machine gating signal generator - uses up=down counter storage of adjustable counter comparison value
Inventor: KUGLER ROLAND ING GRAD
IPC: G05D3/20
Filed: 1977-04-25
Abstract: Arrangement generating a gating signal for controlling recording on a rotary printing machine uses a disc on the machine shaft with studs equally spaced about the perimeter for reference and counting pulse generation. A first counter produces cylinder pulses by comparing its contents with an adjustable value. A second present counter produces gating signals by comparing its input with an adjustable valve. Both are synchronised with the reference pulse. The comparison value is stored in an up-down counter with preset inputs driven by the first counter output and counter inputs driven by a clock generator. Preset inputs are hand switched or controlled by a marker signal. The clock circuit is hand or regulator triggered.
