Patent DE-3013556-A1 (DE)
Title: Continuously curing extrusion - passing from nozzle vertically upwards through calculated height of heated liquid curing medium
Inventor: TSUDA TEIZO
IPC: B29C48/91
Filed: 1980-04-09
Abstract: An extrusion is continuously cured by passing it upwards vertically through a liquid curing medium and continuing its movement upwards. The extrusion enters the curing medium directly. The figure shows an example for externally reinforced extruded tubing. An extruder screw (11) produces the outer layer on to the inner tubing (3A) at a nozzle (20) which enters directly into a tubular curing chamber (23) fed with the heated curing medium. This latter material is e.g. a low m.pt. Sn-Bi alloy raised to 150 degrees C. When the nozzle head details have been adjusted to produce the desired thicknesses of extruded material, the curing medium is switched on and flows into the chamber (23) up to a calculated height (e.g. some metres). Its temp. is maintained by a heater (26) and the space in the chamber (23) above its level receives a current of circulating hot air or, if necessary, an inert gas to prevent oxidation of the curing medium. Suitable method for e.g. "TOLEC" (R.T.M.) curing medium, eliminates problems of curing by passing horizontally through the medium, uniform pressure on extrusion, extrusion is not cooled before entering curing medium.

Title: Track braking system with automatic velocity control - has descent braking section adjusted in dependence on run-through velocity for control braking section
Inventor: POEHLMANN ADOLF
IPC: B61L17/02
Filed: 1980-05-24
Abstract: The track braking system has a control braking section (RB) and a descent braking section, the former divided into initial, main and final rubber track braking stages (VB,HB,NB). The entry and exit velocities of the rail wagon for each stage (VB,HB,NB) are monitored to allow automatic braking release upon the required velocity being reached. The required run-through velocity for the control braking section is used to set the braking criteria of the descent braking section, to ensure that the control braking section is released before full passage of the wagon. Pref. the instant for evaluating the release state of the control braking section is provided by the point at which the last axle leaves the main braking stage (HB). The calculated required run-through velocity in the control braking section (RB) is dependant on the wagon loading.

Title: Time-switch plug assembly for room socket - produces heating current for controlling central-heating thermostat upon connection of load at predetermined time
Inventor: ELTGEN NORBERT
IPC: H01R24/06
Filed: 1980-07-26
Abstract: The time switch plugs into a conventional socket and has its own socket for connecting to a load. The switches contacts connect and disconnect the load from a low voltage supply in accordance with a given time program.

Title: Screw bolt fastening with mortar pressed in hole through wall - involves supply duct into ring chamber formed by base or counter plate recess
IPC: F16B13/14
Filed: 1980-09-13
Abstract: Mortar under pressure is used for connecting a bolt, or screw braced with base plate and counterplate, in a hole through a wall, to the wall itself, with force and form-locking action. On the side facing the hole ( 1), the base plate (4) or counter plate (5) has a recess (9) combining with the bolt (3) to form an annular chamber (8), and a mortar supply channel (10) entering this at an acute or right angle to the bolt. The pressing device is attachable to this. Between wall (2) and base plate, and wall and counterplate, there is a ring disc (14,15) of soft-elastic material. The channel may be prolonged outwards by a pipe (11) with a stop valve (12). The bolt can always be securely joined to the wall parallel to the hole.
Patent DE-3034644-A1 (DE)
Inventor: GREINER HARRY M DR ING
IPC: B41F31/14
Filed: 1980-09-13
Abstract: An inking unit for a printing press including a source of ink, a set of ink transfer rollers for establishing an ink film, a distributor roller vibrated endwise for distribution of the ink film and a form roller for applying the ink film to a plate on the plate cylinder. The form roller has a shaft and an outer cylindrical shell, the latter being rotated by surface engagement. A bearing between the shaft and the shell permits relative axial as well as rotational movement. A cam of the cylindrical, or drum, type mounted on the shaft has an endless wavy groove in which is received a cam follower in the form of a roller extending radially inwardly from the sleeve so that the sleeve reciprocates through a single cycle as a result of a single relative rotation of the shaft. The shaft is driven at a speed which causes the frequency of vibration of the form roller to differ from the frequency of vibration of the distributor roller so that the ghost image on the form roller is constantly being displaced and dissipated both peripherally and axially with respect to the image on the plate resulting in substantially ghost-free printing. A clutch is provided for remote switching between two modes of operation.

Inventor: RODRIGUEZ HORTENSIA NANCY FERN
IPC: D21C9/10
Filed: 1980-10-06
Abstract: Bleaching bagasse pulp is carried out by heating in alkaline medium, treating with O2 under pressure and then bleaching in several stages by chlorination and/or treatment with ClO3 or H2O2, second alkaline extn. and then treatment with a hypochlorite and/or ClO2 and/or H2O2. These stages can be carried out in any sequence. Pref. treatment with O2 is carried out at 4-10 bar and 105-125 deg.C for 30-90 min in the presence of 2-6.8% NaOH and of 0.5-3% Mg salt as degration inhibitor. This can be preceded by pretreatment with an acid. Chlorination is carried out with 1-3% Cl2 for 30-60 min, alkaline extn. with 0.5-3% NaOH for 30-90 min, treatment with 0.4-1.6% hypochlorite (as Cl2)at pH 10-12 for 90-180 min, treatment with 0.2-1%ClO2 in the first stage and 0.2-0.8% ClO2 in the second and treatment with 0.2-1.2% H2O2 at pH 9-11. The process is useful in the prodn. of pulp and paper. It is cheaper and causes less environmental pollution than usual.

Title: Metal window frame with heat barrier anchoring profile - has groove edges scalloped using oscillating tool or spark erosion, to positively locate fitted strip
Inventor: HENDEL ALFRED
IPC: E06B3/273
Filed: 1980-10-15
Abstract: The arrangement is intended for producing a scalloped profile along the edges (7,11; 8,11) of a longitudinal T-section groove of a sectional metal member (1), in which a thermally insulating connector strip is to be secured by bending (5). The strip serves as a heat barrier when the member is used for the manufacture of composite door or window frame elements. The scalloped profile, which positively locates the barrier strip when fitted, is produced by a cutting tool (10,13) or a spark erosion electrode. This is oscillated (12) between the edges whilst the member is continuously moved longitudinally.

Title: Method for regulating the rotation speed of externally-energised DC motors, and a circuit for carrying out the method
Inventor: HAASS ADOLF
IPC: H02P7/29
Filed: 1981-01-07
Abstract: The rotation speed of externally-energised DC motors, to the extent that they are used for driving model railways, is regulated precisely, at a low cost in terms of equipment, in such a manner that the generated armature voltage is measured in the time intervals between the DC pulses which are applied to the motor armature (2), and is compared in a comparator circuit (6) with a required value (7).

Title: Hollowing-out machine
Inventor: AYYOSCH AHMED
IPC: A23N4/12
Filed: 1982-08-06
Abstract: This appliance for hollowing out vegetable-like fruits comprises two main parts: the boring device and the drive. The boring device is coupled by bayonet closure to the main housing (drive). On the boring rod there are six cutting blades, distributed over the circumference, which are firmly soldered onto the upper part of the boring rod. The lower part of the cutting blades is fastened on a displaceable annular disc. By pressing the disc upwards in the axial direction, the peeling blades are forced into an arcuate shape. At the same time, the boring rod, including the peeling blades, rotates, driven by the electric motor. Consequently, the vegetable-like fruit can be hollowed out.
