Abstract: The invention relates to a method and an apparatus for the transfer of concrete panels onto a transportation bed for transportation. According to the method, the transportation bed is driven to underneath the load to be transferred, the supports (1) are subsequently inclined in their transverse direction until they transfer the load onto the bed. In accordance with the invention, supports (1, 7, 6) are used, the leg members (1, 7) of which are provided with tilting joints (8, 9) in the direction of inclination, said joints being preferably fitted at the lower ends of the vertical supports (1), at the joints between the vertical supports (1) and the horizontal beams (7). The vertical supports (1) of the leg members (1,7) of the stands (1, 7, 6) are preferably inclined by about 30 DEG by connecting one of the stands with a pulling bar to the transportation bed and by pulling the load on the supports forward in this manner. The inclining movement of the stands is damped by a spring (15) or a shock absorber, installed between the vertical support (1) and the horizontal beam (7), whereby the concrete panels can be transferred by means of a controlled and attenuated movement onto the transportation bed.

Abstract: The invention concerns a method and an arrangement for generating smoke for smoke treatment of foodstuffs. The smoke is developed by means of a technique in which combustion takes place from above, the smoke being used only when there is a charcoal layer of 0.5 to 100 mm on the fuel stack, which has arisen during combustion of the fuel. The charcoal layer acts as a regulator of the combustion air flow, the combustion being allowed to take place at a temperature which is advantageous as regards the development of odours and hazardous substances. The layer of charcoal also acts as a selective filter and removes hazardous substances from the smoke. <IMAGE>

In a system in which alternating currents selected by a key-set are sent from a subscriber's substation to the main exchange to signal the wanted number, these signals may also be used to signal the class of service of the subscriber. The class of service may be placed under manual control of the subscriber. In one embodiment for two-party lines two oscillators, powered from the main exchange, are provided. One oscillator provides frequencies E, F, G, H and the other providing frequencies A, B, E or C, D, E for X and Y party strappings. Digits 1 . . . 8 are sent as a combination of one of frequencies E, F, G, H with one or other of A, B in the case of an X-party and with one or other of C, D for Y-party. Frequency E is used only on 9 and 0 or 0 (barred trunks) where X- and Y- party discrimination is unnecessary. The key 0 produces frequencies G, E or H, E according as the manually operated barred trunks key is or is not thrown. In a second embodiment three oscillators are used, two giving the ordinary two-out-of-five frequency code for the digits and two extra frequencies F and G being provided for X and Y party discrimination, a further combination involving F and G being used for 0 (barred trunks). In a third embodiment frequencies are arranged in narrowly spaced pairs. Digit determination can then be effected using wide-band filters capable of accepting either of a pair, and X- or Y-party discrimination being then effected using narrow band filters.

Title: Method and system for condensation of unprocessed well stream from offshore gas or gas condensate field
Inventor: BENCZE ISTVAN
IPC: B63B22/02
Filed: 2003-12-23
Granted: 2007-02-14
Abstract: In a method of condensing an unprocessed well stream from an offshore gas or gas condensate field the well stream taken from one or more wellheads is cooled and directly expanded, isentropically, or near isentropically, to a state in which the pressure is close to that of a storage tank. Part of the well stream is condensed and condensed fractions thereof is drawn off the expander and fed to the storage tank along with condensation products from the exit of the expander. Hence, without any preprocessing, a condensed well stream product is produced which comprises a mixture of liquids and solids which is collected in the storage tank for transport therefrom to land. A system for carrying out the method is also disclosed. The invention makes the condensation of an unprocessed well stream possible without any preprocessing thereof, such as extraction of solid particles, e.g. sands, removal of water, cleaning or drying. Thus, by means of the invention smaller gas or gas condensate fields can be developed in a more cost efficient way.
