Title: Process for draining a fibre material web, in particular a paper web or cardboard web, and a papermachine wet press using the process
Inventor: SKYTTAE OSMO
IPC: D21F3/02
Filed: 1985-09-30
Abstract: In the process for the press treatment of a fibre material web, in particular a paper web or cardboard web (W), a press nip (NL) is used which is formed between two press rollers (10, 11) and through which the web (W) to be dried by pressing is carried by a cloth or a water-absorbing belt or passed between cloths (17, 24) and/or a water-absorbing belt. In addition, one or more elastic press belts (30) are passed through the press nip. The maximum pressure force (pmax) to be exerted in the process is selected between an upper limit (p2) and a lower limit (p1), the upper limit (p2) being less than 130 bar and less than the function p2max (L) which, with increasing length (L) of the press nip, is a decreasing function whose curve is determined mainly by the maximum available pressure momentum (Imax), and the lower limit (p1) being greater than 50 bar. The diameters of the said press rollers (10, 20) are selected in such a way and, as the said press belt, an elastic belt (30) is used whose thickness, construction and viscoelastic material properties are selected in such a way that, in the abovedefined range (p2-p1) of the maximum pressure force, the following length range (L) for the extended press nip (NL) confined between the rollers (10, 20) is designed with the following upper limit L2 and lower limit L1: L2 < 200 mm, ...

Due to the two-piece gas cup with a nozzle holder screwed to the torch tube and an insert nozzle which can be inserted into the nozzle holder, the gas-cup change is simplified, the amount of material required for the wearing parts to be exchanged is reduced, and the quality of the inert-gas jet is increased.
Patent DE-3538495-A1 (DE)
Title: Food
Inventor: SIEBKE INGO
IPC: A23L19/12
Filed: 1985-10-30
Abstract: The invention relates to a ready-roasted or ready-fried prepared food in the form of a ready-to-eat prepared dish. The food is shaped in the manner of croquettes and has a single or multiple component filling which is encased by a dough-like mass, in particular a potato-like mass. The filling can have a solid or pasty consistency. The food according to the invention, after deep frying, is available for consumption in compliance with the requirements for finger food or fast food. Since the filled croquettes are not coated with breadcrumbs and the casing gives off virtually no fat to the outside, the opportunity is offered of eating the croquettes without use of an aid, that is using the fingers, without the fingers becoming grossly contaminated in the course of this. As a result of the absence of a breadcrumb coating, no deposits form in the deep frying fat, which deposits would relatively rapidly carbonize as a result of the action of heat.

Title: Training device for remote control of model helicopters in free flight
Inventor: NAIVERT KAREL
IPC: A63H27/133
Filed: 1985-12-19
Abstract: The invention relates to the negative results achieved when using model helicopters with the previously available practise frames which have a specific hinged connection between the frame and the helicopter and hence produce an unnatural flying behaviour of the helicopter while the pilot is practising. Thus, all the said disadvantages are overcome by a novel device system developed by me, in that the behaviour of the helicopter body during practise maintains a natural flying attitude precisely, as in the case of control reaction. In favour of this free-flight device is the fact that the practise time is reduced by the said advantages, so that a person who is interested in this sport has his interest stimulated in a positive manner.

Title: Control loop for deflecting cathode rays in display devices
Inventor: SPIETH ROBERT H
IPC: H04N5/12
Filed: 1986-03-21
Abstract: A circuit arrangement for synchronising a sequence of horizontal deflection current pulses of a cathode ray display with a sequence of synchronisation pulses contains an adjustable delay circuit which, in turn, is triggered by a synchronisation signal and triggers the generation of the deflection current pulse after a predetermined time delay. The delay is automatically controlled by a feedback loop in which the existing delay is measured by means of an RS flip flop, which outputs output pulses, the duration of which is equal to the delay. An integrator forms the mean value of the pulse chain coming from the flip flop and logically combines a reference signal with the mean value in order to generate by this means a control signal for the delay. The circuit arrangement operate with minimum bandwidth and dynamic characteristics which are free of acquisition restrictions in order to produce by this means minimum sensitivity to interference.

Title: Mixer, distributor or coupler for at least three optical waveguides
Inventor: KAYED JALAL DR
IPC: G02B6/28
Filed: 1987-03-06
Abstract: In optical telecommunications technology, the light which is guided through optical waveguides is mixed or distributed in multi-gate elements. Mixers or distributors of this kind have previously been characterised by the use of high-quality types of glass and by complex mechanical operations for the production of these elements. The core component of these elements, a so-called mixer wafer, must for example be cut very precisely, ground, polished, lapped, fixed and appropriately bonded. The invention is based on the fact that the mixing or distribution of the light which previously took place in the mixer wafer can also be achieved in an optical immersion medium (3; 4). Optical fluids (4) or optical bonding agents (3) can be used as optical immersion medium (3; 4), bonding agents which cure in ultraviolet light being particularly significant. The invention provides for an optical multi-gate element to be produced by means of a single capillary (1) made of quartz glass in which the immersion medium (3) is located, into which in turn the ends of the optical waveguides (21, 22) are fixed using a bonding agent after they have been adjusted. The immersion medium ensures, in a distributor, for example the mixing of the incoming light over the entire inner cross-sectional surface of the capillary (1) and uniform distribution of the light to the outgoing optical waveguides (22). Mixers, distributors or couplers which are designed in this way ... Original abstract incomplete. <IMAGE>

Title: Torque-compensating gear unit
Inventor: BOUDEELE RENE
IPC: F16H1/28
Filed: 1987-04-16
Abstract: Torque-compensating gear unit for transmitting the torque of an assembly, using its moment of inertia to compensate for reactions. In the transmission of torque, reactions which drove the assembly in the opposite direction have hitherto arisen. The absorption of these forces led to technically complex solutions without eliminating them.   This planetary gear unit is mounted on the assembly. The driving torque is taken by the internal gear and transmitted via toothing to the planet gear, where the driving torque is taken off. The planet carrier is part of the gear case. During transmission to the planet gear, the direction of rotation is changed and this gives rise to a reaction to the driving torque of the same magnitude and the same direction which is the resultant of the moment of inertia of the case, which is reduced to this, its mass about its axis of rotation.
