Title: Systems and methods for load balancing across media server instances
Inventor: NETHERCUTT GLENN THOMAS
IPC: H04L29/08
Filed: 2018-08-30
Granted: 2021-11-25
Abstract: A system and method are presented for load balancing across media server instances. In an embodiment, media is broken out into a multi-tenanted service allowing the media to be scaled independently of the number of organizations supported on a cloud-based collaboration platform. Scaling may occur in a scaling-out or a scaling-in operation. States for a media service may comprise in-service, quiescing, quiesced, failed, etc. The states may be used to monitor sessions associated with an instance and determine which media instances to terminate during a scaling-in operation. In an embodiment, new instances may be added to a collection of media instances in response to an increased workload in a scaling-out operation.

Abstract: <HO>Multi-needle sewing machine for the longitudinal quilting of piping of seat coverings</HO>     A process for operating a multi-needle sewing machine for the longitudinal quilting of piping of seat covering is indicated, in which the under-cloth and the strip-shaped piping filling material are supplied as stock and an over-cloth blank is applied. The piping filling material is guided in channels which are open towards the under-cloth and which have run-on slopes on the entry side, so that the over-cloth blank, fixed at the edge by a co-running clamping device allowing transverse displacements, comes to bear on the run-on slopes during its transport and, during further transport, is guided by the side walls of the channels round the longitudinal edges of the piping filling material, the material being added laterally. Holding-down devices following the channels extend directly in front of the needles, so that a crease-free sewing pit is maintained and the sewn covering, which is severed from the web by means of a severing cut, is distinguished by plastically protruding piping.

Title: Method for demodulating a frequency-modulated data signal
Inventor: ANNECKE KARL-HEINZ DR-ING
IPC: H04L27/156
Filed: 1984-10-19
Granted: 1986-04-03
Abstract: The invention relates to a method for demodulating a double frequency-shift keyed (2-FSK) data signal which is sampled cyclically, by means of two delay components, three sampling values being combined in such a way that the output signal is directly proportional to the instantaneous frequency, and is characterised in that three consecutive sampling values are in each case weighted with different factors and are then added together. In a first solution, the summation signal is then multiplied by the second sampling value and the result checked for 0 by means of a comparator at whose output the demodulated signal occurs. In a second solution, the adder output signal and the second sampling value are in each case checked for 0 by means of a comparator whose output signals are compared by an EX-OR component at whose output the demodulated received signal similarly occurs (Figure 3). <IMAGE>

Title: Casing for a fire detector
Inventor: JAKIM PETER DIPL-ING
IPC: G08B25/12
Filed: 1986-03-14
Granted: 1987-07-23
Abstract: The casing for a fire detector comprises a casing trough, for receiving a detecting insert, and a door (3) which is articulated, such that it can be folded down, on the casing trough and has a window cutout (9) which is closed by a glass pane (11) and through which the detecting insert is accessible.

Title: Powder coating device
Inventor: TALACKO RADOVAN DIPL-ING
IPC: B05B14/48
Filed: 1986-05-10
Granted: 1987-08-13
Abstract: Said device includes a powder container (12) for fresh coating powder and a metering device (32), by means of which powdered additional material is conveyed from a further container (36) in a metered amount into the powder container. As a result, the free-flowing properties and the capability of undergoing triboelectric charging of the coating powder can be improved and segregation of the additional material from the coating powder is prevented. Since the powder coating device even adds the additional material into the coating powder in a precisely metered manner, it is no longer necessary to buy and keep in stock a separate mixture of coating powder and additional material for each powder colour. <IMAGE>

IPC: G01S17/10
Filed: 1991-12-16
Granted: 1993-02-25
Abstract: A method of measuring the thickness of a film of water, snow or ice on a surface involves directing pulsed l.m. radiation obliquely from above onto the surface and measuring and evaluating the reflected radiation. The transition time difference is measured between pulsed signals reflected at the surface of the covering film and at the covered surface. The film thickness is derived from this time difference. Time resolved signal reception is performed to enable the time difference to be determined from the time variation of the received signal.

Title: Continuous removal of organic coating, e.g. resin, from steel pipe - involves heating pipe with a medium frequency induction coil and burning off to remove coating completely without thermally degrading steel
Inventor: FOERSTER HERBERT DIPL ING
IPC: B08B7/00
Filed: 1993-02-10
Granted: 1994-02-24
Abstract: An organic coating on hollow metal bodies, esp. steel pipes, is removed where they have an epoxy undercoat and an ethylene-copolymer to coat, and the surface is cleaned off mechanically for renewed application of the organic coating. The metal wall is uniformly heated to at least 200 deg.C but max. 350 deg.C by induction heating at medium frequency, the coating is then immediately heated externally in the presence of oxygen so that it is thermally broken down at at least 400 deg.C but max. 550 deg.C but without causing the metal wall to exceed 400 deg.C. The product is then subjected to the mechanical cleaning. ADVANTAGE - The procedure is continuous. It effectively removes all coatings from the metal surface but without heating it enough to affect its properties.

Patent DE-4333259-C1 (DE)
Inventor: DALSTEIN THOMAS DIPL ING
IPC: H02H7/26
Filed: 1993-09-27
Granted: 1995-05-24
Abstract: The invention concerns a method of generating a signal indicating the direction of a short-circuit in an electric power-transmission line to be monitored. In order to be able to produce such a signal reliably even in the event of a short-circuit in the vicinity of the control point, each current and voltage signal (JR(t)) derived is separately sampled and normalized to give different normalized sample values (JRn). Using triggering reference values (Sn), difference values ( DELTA iR(t),  DELTA iR(t-1),  DELTA iR(t-2),  DELTA iR(t-3)) are calculated, difference values [ DELTA iR(t),  DELTA iR(t-1), DELTA iR(t-2),  DELTA iR(t-3)] from one series (SiR) being applied successively, at the same time as difference values corresponding to the same times from the other series (SiS, SiT, SuR, SuT), to various input neurons (50...53; 76...79) in an appropriately taught neuronal net (55). In the event of a short-circuit in one direction (the forward direction), the signal (Sm) from the output neuron (82) exceeds a predetermined upper threshold value (0.8) while, in the event of a short-circuit in the reverse direction, the output signal (Sm) falls below a predetermined lower threshold value (0.2). The difference in size of the output signal (Sm) is used to generate the appropriate direction signal (RS).
