Title: Method for recording and playback of recording media and playback arrangement for implementing the method
Inventor: LOFBERG BO
IPC: G11B23/28
Filed: 1980-09-26
Abstract: When recording a program on a recording medium of the optical disk or magnetic tape type, the program signal INF is encoded 1 before being registered 2 on the recording medium RC or a material for its manufacture. During playback of the recording medium by means of a common playback arrangement 4 for the particular type of recording medium, the program signal CINF played back is decoded 5 by using decoding information which is obtained from the user's personal data medium ID. At the same time as the decoding, a personal identification information is introduced into the decoded program signal DINF. The personal identification information is introduced preferably in such a way that it is not noticeable when playing back the program signal with the help of a common playback machine. Playback of the recording medium requires access to necessary decoding information, which is assumed to be secret and which is temporarily saved on the personal data medium. This necessitates use of the personal data medium, whereby the personal identification information is necessarily introduced into the decoded program signal. When transferring the decoded program signal to a recording medium of the same or different kind, the personal identification information will always end up on the copy thus produced. With the help of the personal identification information and data stored in conjunction with the obtaining of the personal data medium, such a copy can be traced back to a particular person. This provides protection against unauthorised copying of pre-recorded media. <IMAGE>

Title: Braking arrangement for a wheeled cross-country training ski
Inventor: ERIKSSON JOHN MARTIN
IPC: A63C17/14
Filed: 1982-11-10
Abstract: The invention concerns a brake arrangement for a wheeled cross-country ski to simulate the action of the force of propulsion at the binding against the base during actual skiing and the ski contains a foot plate with at least one front wheel 1 and at least one back wheel 3 provided with a brake 2, which foot plate is designed to support the skier's boot and has a front and a rear part 4, 5, which parts are hinged together to turn about a horizontal axis of rotation and are prestressed into a normal position by means of a spring element 9. Furthermore, there is a lever system 2, 6 arranged to influence the brake 2 when there is a change in the angle between the parts from the normal position, in accordance with the size of the change. In order to achieve an even more lifelike function of the training ski with regard not only to the vertical component of the force of propulsion but also the horizontal component thereof, the invention proposes that the axis of rotation 15 is situated essentially directly underneath the back edge of the sole of the boot fastened to the foot plate and the lever system contains an actuating arm 6 firmly joined to the front part 4, which extends backward past the axis of rotation 15 and is designed to act on the brake 2 not only when there is a rotation between the parts 4, 5 of the foot plate from the normal position, but also upon lengthwise backward motion relative to the rear part 5. <IMAGE>

Title: Heating system valve assembly for house
Inventor: BROSENIUS HILDING
IPC: F24D3/10
Filed: 1985-08-23
Abstract: A heating system comprises radiators with corresp. rise and return pipes, a heat source and an expansion tank system. A water pump circulates water between the heat source and the radiators, the heat source being located on a lower level than the radiators. The heat source is directly or indirectly provided at the top with an open outlet, the radiator system water pressure above this outlet being produced by the normally permanently functioning water circulation pump. The position of the valve arrangement is such that the return pipe is held open so long as the pump pressure is maintained, but closes if the pump pressure ceases through power failure or pump fault. In turn, tapping off water from the radiators at the bottom as the result of pump stoppage is prevented.

Title: Process and device for producing glass spheres, and spheres which are produced thereby
Inventor: BRAUN R K
IPC: C03B19/10
Filed: 1987-04-06
Abstract: A method and a device for forming spheres from irregularly shaped, very small particles of glass or other thermoplastic material, and the spheres which are produced thereby, with a thin carbon-containing coating being applied to the particles, after which the particles are caused to pass through successive fluidized beds 15, 110 and 130. The first bed 15 has an inert atmosphere and is maintained, by means of heating elements 67, 69, 70 at an elevated temperature which is sufficiently high to permit surface tension to shape the particles into a spherical form while they are in a fluidized state in the first bed 15. A fluidizing material is introduced into the bed by means of elements 53, 54, 55, 56, 57 for suspending the particles therein and fluidizing it in such a way that the particles move at an essentially constant level the whole time they are in the bed. The spherical particles subsequently pass through successive additional beds 110 and 130, where they are cooled down to an intermediate temperature, which is sufficient to cause the particles to solidify, are exposed to an oxidizing atmosphere, which completely removes the coating, and are then cooled down further while being maintained in a fluidized state. The inert gaseous atmosphere inside the first bed 15 is withdrawn continuously and recirculated through the system. <IMAGE>
