Title: Procedure and device for smoking food prods. - comprises circulating smoke through smoking chamber and mixing with steam which accelerates process by condensing on surface of prod.
Inventor: NESS EDUARD DIPL ING
IPC: A23L3/3409
Filed: 1990-06-05
Abstract: When a prod. is smoked in a chamber, steam is mixed with the smoke before it enters the chamber, and the temp. of the steam/ smoke mixt. is kept higher than that of the prod. The smoke may be circulated through the chamber in a closed circuit. The flow of the mixt. in the chamber is made turbulent. A smoke producer is pref. connected by smoke flow and return pipes to the smoking chamber, and a steam supply pipe opens into the smoke flow pipe near its entry into the smoking chamber. A fan provides a turbulent smoke flow in the smoking chamber. An isolation valve, a strainer and a regulating valve are provided in the steam supply pipe. USE/ADVANTAGE - For smoking food prods. to preserve and improve the taste. The smoking process is accelerated, since the steam condenses on the prod. and therefore deposits some of the smoke particles on its surface.

Title: Doubled yarn splicing - has separate splicing stations set up for different types of yarn components
Inventor: FUJIWARA MICHIAKI
IPC: D01H15/00
Filed: 1990-08-28
Abstract: To splice a break in a doubled yarn where, at a spinning station, two yarns of different types are spun simultaneously and are doubled together for winding, they are cut automatically at the doubling point when a break is regisitered in one of the components. The yarn sections are caught by a suction unit and are sepd. without laying in the doubling guide, to be passed to separate splicing stations where each yarn component is spliced with the same type. The doubled yarn at the winding bobbin is carried by a suction tube to a cutter with separate yarn components leading back to a guide in front of the bobbin where they combine. On a correct lie, the separate yarns from the bobbin are each spliced with one of the same type from the spinning station. On an incorrect positioning, the doubled yarn from the bobbin is cut, the components sepd. and the waste removed, and further laid until the sensors register that they are in place. ADVANTAGE - The method allows for the different types of yarn making up the doubled yarn, giving an effective splicing with min. waste.

Title: Produce peeling appts. - has screw conveyor within trough of counter rotating peeling rollers
Inventor: RIECHELMANN HARRY
IPC: A23N7/02
Filed: 1991-06-12
Abstract: The appts. to peel agricultural produce in an industrial application, such as for root vegetables and certain fruit, has a trough conveyor screw to carry the material from the feed to the outlet. The screw is within a trough, and has a constant screw pitch. The rotary speed of the screw can be varied, as it carries the produce through the peeling operation. Pref. the trough is formed by powered peeling rollers, powered in two gps. by two drives. They are rotated in opposite directions according to the loading and quality. The peeling rollers have structured edges, similar to smooth cut files, with deeper milling at the feed end, becoming smoother towards the outlet, so that the produce is virtually smooth when it emerges. For maintenance, and a rapid peeling roller exchange, a snap coupling in on a double-bearing drive journal at the drive end, and a roller bearing is inserted into the end plate at the take-off end. A fine sieve trap and material removal unit is built-in below the trough. The sides of the machine frame are covered by suspended plates of a non-rust and non-damaging to foodstuff material, to catch water sprays. ADVANTAGE - The appts. gives an even peeling action to the produce, which passes through the systems without bunching or clogging.

Title: Thermal cleaning process for electrostatic filter for airflow in wood panel production - has electrodes heated periodically to fluidise deposited layers for disposal
Inventor: BOEHLER HARALD
IPC: B03C3/45
Filed: 1991-08-11
Abstract: The extract air from the wood panel processing is cleaned through electrostatic filters where water vapour, resin fumes, wood particles etc. are collected. The collected substances grow layers on the filter and are removed by directly heating the electrodes. This fluidises the layers and the fluids are collected for disposal. Electric heating can be used, or a heated coolant. Alternately a heat recovery cycle from the exhaust air can provide the necessary heat. The processing unit can have parallel filters, enabling one set of filters to continue operation while the other set is cleaned. The fumes released during cleaning can be handled in the other filters. ADVANTAGE - Efficient, cost effective management of process filters.

IPC: A47F3/04
Filed: 1991-08-14
Abstract: The invention relates to a refrigerated display cabinet whose refrigerated goods compartment is accessible via at least one glass door, and in which the pane and/or the frame of the glass door and/or the contact profile of the glass door can be heated electrically in order to avoid condensation of water vapour on the inside and outside of the pane. In order to be able to switch the electric heating off during shop closing times, an energy-saving insulation cover is positioned vertically in the refrigerated cabinet between the refrigerated goods compartment and the glass door. A cold-insulating plastic is used as an energy-saving insulation cover. Furthermore, a coating serving for additional cold-insulation can be applied. <IMAGE>

Title: Quick method of repairing skid belts - by removing top and bottom rubber covers from core at two ends, holding belt taut around system of rollers, and joining ends
Inventor: HOLLMANN MANFRED
IPC: F16G3/06
Filed: 1991-09-12
Abstract: The two ends of a skid belt are bonded together quickly in a repairing method, whereby the top and bottom covers are removed from the tensile strength core at each end, and the ends of the core are fixed together in a clamping device. The skid belt (1) has a high tensile strength core (2) of aramid cord threads with top (3) and bottom (4) covers of rubber. The mechanical repairing equipment removes these top and bottom layers (3,4) from each end of the core (2); it has two lower clamping (e.g.) tubes (7) which can revolve, a top centre tube (8) which can also revolve, and two other turning tubes (9). One free end of the core (2) is passed round one of the lower tubes (7), through the gap (11), round the tube (9) and then between itself and the lower tube (7). The free end can now be cut if required. The system of tubes grips the core (2) tautly. The lower cover (4) at one end of the belt (1) is stripped from the core (2) but not removed (unlike the others). When the complete belt (1) has been mounted and held taut the lower cover (4) is appropriately cut, so that this cover (4) has a smooth surface. ADVANTAGE - This improved method is quick and produces durable bonds even when the belts use cord thread. The equipment used ensures that the joints can withstand high loads and will pass smoothly around rollers.
