Patent SE-7608834-L (SE)
Inventor: DAVIDSON JR A R
IPC: G10K11/16
Filed: 1976-08-06
Abstract: An array of independent sound cancellation units is arranged over a vibrating noise generating surface. Each unit includes an arrangement of acoustic transducers (sensors) positioned adjacent the surface to obtain an electrical average of the local acoustic noise generated by a predetermined zone of the surface. The summed average is changed in phase and gain by an active filter whose output drives an acoustic projector also positioned adjacent the surface and the acoustic output of which sums with the original noise signal in the acoustic far field, thus tending to cancel the noise. In essence, each vibrating surface zone and its associated sound cancellation unit tend to form an acoustic doublet. A signal indicative of the projector output is used as a feedback signal, with appropriate time delays, to cancel the effect of the projected output signal being picked up by the unit's transducers, and to cancel the effect of the output of other projectors of the array.

Abstract: A broadcast receiver includes an automatic search tuning arrangement, the tuning being automatically selected on operation of switches which correspond to a number of regions (A . . . F) and other switches which correspond to the chosen program (VF, P1, P2 or P3). These switches cause a control circuit (59) to address a gate circuit (95) to sequentially produce an output corresponding to a subarea of a region to be applied to an address memory (93) of a memory circuit (23). The address memory in turn causes a memory (33, 35, 37 or 39) corresponding to the selected program to produce codes stored therein which correspond to the transmission frequencies of that program and which are used to control the output frequency of a local oscillator (7) via a phase locked loop. The transmission chosen for reception is determined by a count of the number of receivable transmissions corresponding to tuning data from one and the same group.

Abstract: This invention is related to a method of making a lead storage battery with a thixotropic gel as electrolyte consisting substantially of a sulphuric acid and a gelling agent. The object is to provide a lead storage battery which is maintenance free, leak-proof and of a long cycle life while permitting filling of the electrolyte independently of the plate dimensions including the superficial extent of the plate. To achieve this object: (a) the sulphuric acid is electrochemically bonded in the active material of the electrodes; and (b) the gel forming electrolyte is filled into the battery in the form of a gelling agent and a sulphuric acid concentration which is insufficient for the formation of a gel, but which is sufficient for initiating a charging process upon application of a charging voltage. During the charging process the sulfuric acid that is bonded to the electrodes, together with the gel forming electrolyte, will start the formation of the gel.

Abstract: A mechanical central buffer coupling for a so-called model Scharfenberg for rail vehicles which have a main conduit connected to a coupling lock in a brake actuator coupling lock, comprises a controlled pneumatic valve for opening the lock which is characterized by an air valve connected with the main air conduit and to the pneumatic valve. The air valve is connected to the brake actuator so that in case of unintentional severing of the central buffer coupling the air valve actuates the brake of the rail vehicle by venting the main conduit. The model Scharfenberg mechanical central buffer coupling generally includes an arrangement of a rotary pivotable lever system between two mechanical coupling members in such a way that the mechanical coupling members can pivot even without moving the lever system, so as to make possible an actuation of the air-shut off member only upon actuating the releasing device of the coupling members but not heretofore upon an unintentional severing of the coupling members.

Abstract: A method for draining liquid from, for example, a liquid separator in a pressure-gas conduit, with the aid of a valve. The invention is based on the concept that when a fluid flows through two constrictions connected in series, the pressure between the constrictions will vary in dependence on whether the fluid is a gas or a liquid. In the former case the pressure will be higher, and can therewith be used to close the constrictions. The invention also relates to a valve for carrying out the method, the valve comprising an inlet (32), a first constriction (33) which opens into an intermediate pressure chamber (36), a second constriction (34) located between the intermediate pressure chamber (36) and an outlet (41). A valve body (35) located in the intermediate pressure chamber is arranged to be activated in a direction which closes the constrictions (33, 34) by the pressure prevailing in the intermediate pressure chamber (36) and in an opening direction by the pressures prevailing in the constrictions (33, 34), the pressure in the intermediate pressure chamber (36) being increased when gas appears in the first constriction (33) instead of liquid, and the pressure increase and the areas of the constrictions (33, 34) being adapted so that the valve will close in response to the aforesaid increase in pressure.

Abstract: In known lung-controlled valves, the positive pressure in a breathing connection is established by the fact that the control diaphragm of the valve is tensioned by spring force. There, however, the opening force brought about by the spring is greatest when the inlet valve is closed, while it is smallest when the inlet valve is completely open. To keep the opening force as small as possible with the valve closed, and to leave the opening force approximately unchanged with increasing opening of the inlet valve, a magnet is provided on the inside of the housing cover of the lung-controlled diaphragm and the control diaphragm comprises a magnetizable part which is held at a minimum distance from the magnet by spacers when the inlet valve is closed.

Abstract: The invention relates to a method of equalizing blockages in a partioned cell mobile radio communication system with overlaid channel reuse patterns, so called cell clusters. A mobile station can be assigned a channel which belongs to a cell cluster with less cells (small cells) than remaining cells (large cells) in the system. The small cells are overlaid the large cells. The invention is based on the fact that if, for a constant number of channels (3n+9m) in the system, a channel is moved from the large cell group (the 9-cluster group), then the number of channels in the small cell group (the 3-cluster group) increases by a factor = the relationship between the channels in the large cell and small cell groups, respectively. In such a system the blockages for mobile stations far away from the base station can be much higher than for mobile stations near the base stations. A plurality (k) of the channels (m) which are available in the large cells outside the small cells solely for the traffic (B) in this area is reserved, these channels being blocked for the traffic (A) within the small cells. Different ways of reserving these channels are described, so that a favorable equalization of the blockages in the system is achieved.
