IPC: H04R17/00
Filed: 1986-05-20
Abstract: The hydrophone containing a signal processor, incorporates a container, the cover of which consists of the converter body and fixtures for a number of elements (4). The elements each comprise a piezo-electric sheet of plastic e.g. polyvinyl fluoride, and has an elliptical shape with pointed drawn-out ends to provide small side lobes. The thickness of the plastic can vary over a wide range, but is normally around 0.6 mm.. The two sides of the plastic (10) have linings (11, 12) consisting of metal granules in a binder. Ring-shaped slots (13) are stamped out of the side facing the baseplate in each case side. A lead (16) passes through a plate hole to the signal processor, and in the same way the field formed by the division of the sheet or lining by the slots is connected to the processor by leads (17). The element is thus divided into independent parts, each comprising a field and corresp. area of the lining on the other side as electrodes, and the in termediary piezo-electric plastic material. The electrodes (11) are connected via an amplifier (18) to a summation unit (19), and a low pass filter (20) is connected in the intervening lead (17). The file filter is allocated two limit frequencies (f1, f2), the value of which is diminished with increasing size of the electrodes.

Abstract: The tire crampon comprises a cross-shaped member having four arms, interconnected by half-braces bearing bushes for connection to a vehicle's wheel hub bolts. Counter-arms are slideable on the arms and each have a toothed sector rigidly associated with an end thereof. The counter-arms move radially outwardly away from the cross-shaped member upon having a centrifugal force applied thereto, and due to the biasing action of compression springs acting between the arms and the counter-arms, thereby causing the toothed sectors to grip the ground. Chains limit the excursion of the counter arms, which can also be locked in a retracted position by pawl devices.

Abstract: A vacuum beam product dispenser and singulator to dispense and singulate "soft" products in an automated order dispensing system (AOS) is comprised of a product cartridge and an inclined conveyor belt. The conveyor belt picks the products from the bottom of the cartridge using a vacuum control element and carries it up the conveyor until it reaches a pinch roller that holds the product ready to be dispensed to a central conveyor of the AOS. Products are picked from the product cartridge by the inclined conveyor in an unbalanced position such that a product will fall off the conveyor unless held by a vacuum generated by the vacuum control element. Thus, random multiples removed from the cartridge with the picked product fall off the conveyor. The product stream from the hopper is thereby singulated. <IMAGE>

Abstract: An outreach limit (11) is provided in order to prevent overloading leading to overturning of the boom crane (10) of a telescopic boom having a main boom (12) and at least one extension boom (17). The support points (19, 20) between the main boom and the extension boom have been connected to the main boom so that the distance (a) between the support points will remain constant when the extension boom is pulled out. The function of the outreach limit is based on the measurement of main boom deflection. According to the invention, the outreach limit (11) involves a measuring bridge (31) fastened at both ends (21, 34) to the main boom (12). The bridge will bend to the opposite direction compared with the main boom so that when the outreach limit is in operation, its sensors (24, 25 and 30) will feel the total deflection of the main boom and the measuring bridge. <IMAGE>
