Patent DE-4234299-A1 (DE)
Title: Convection baking oven - has upwards diagonal air flow to expand usage to baking large loaves
Inventor: FISCHER GEORG
IPC: A21B1/26
Filed: 1992-10-12
Abstract: The oven with recirculating hot air, to take a trolley with a number of levels to carry the products for baking, has a diagonal hot air flow upwards from below, to flow over the material being baked, and mainly strike against the under surfaces of the baking plates. The lower section of the feed and distribution channels is connected to the energy supply section. The feed and distribution channels have an upwards tapering cross section so that the diagonal hot air outlet is stabilised over the whole height of the baking zone. The cooled hot air is extracted by suction at the energy section through an opening. The suction opening is opposite the feed to the distribution channel, at the upper side of the baking chamber and at the lower side of the energy section. USE/ADVANTAGE - The convection oven is for a bakery. The air flow system allows the oven to be used not only for bread rolls and small baked items, but also for large loaves.

Title: Cutter support for underwater granulator for thermoplastics - locks axial movement of cutter shaft as cutter passes extrusion holes to reduce vibration
Inventor: YAMASAKI NOBUHIRO
IPC: B26D1/14
Filed: 1992-11-27
Abstract: An underwater granulator has a removable water chamber attached at the extrusion end of a thermoplastics extruder. A rotating cutter is held aganst the nozzle plate by a shaft which is mounted in a housing so that it can rotate and move axially. Constant pressure is exerted through a hydraulic actuatng cylinder which compensates for the wear of the cutter. A locking mechanism intermittently prevents axial movement of the cutter shaft. A pick-up provides signals which coincide with the cutter blades covering the extrusion holes and thus being exposed to the full extrusion pressure. An auxiliary hydraulic actuating cylinder moves a clamping screw in unison to prevent axial movement during this period. The constant pressure provided by the main cylinder can therefore be of relatively low value so that wear on the cutter is reduced. USE/ADVANTAGE - The invention reduces vibration of the cutter shaft and cutter wear.

Abstract: The invention is based on a cold-air refrigerating installation with a pre-compressor (1), a first heat exchanger (3), a motor-driven post-compressor (4), a second heat exchanger (6) and an air expansion turbine (2) which drives the pre-compressor (1). In order also to be able to operate this cold-air refrigerating installation as a closed heat pump for heating the air, it is possible according to a first basic arrangement to provide a third heat exchanger (27) which can be connected into the circuit between air expansion turbine (2) and pre-compressor (1), as a result of which a heat pump installation with a pre-compressor (1) - post-compressor (4) - second heat exchanger (6) - air expansion turbine (2) - third heat exchanger (27) - pre-compressor (1) circuit is formed. With the third heat exchanger (27), heat is extracted from the environment and, with the second heat exchanger (6), outside air is heated and pushed into an incoming-air duct (24). According to a second basic arrangement, an open heat pump installation with an air expansion turbine (2') - second heat exchanger (6') - pre-compressor (1') - post-compressor (4') air guide is formed, the air expansion turbine (2') drawing in outside air, heat being extracted from the environment with the second heat exchanger (6') and supplied to the air, and this air being heated in two stages and pushed into an incoming-air duct (24') with the pre-compressor (1') and the post-compressor (4'). <IMAGE>

Title: Process for coplanar free bending of tubes, bars or similar
Inventor: REIGL MARTIN DIPL ING
IPC: B21D7/00
Filed: 1994-09-09
Abstract: The process forms curves in a workpiece, by displacing and rotating its ends, which are held tightly in clamps. The applied forces, couples and bending moments generate a region of plastic flow in the workpiece at the position of the largest positive bending moment, and also at the position of the smallest negative bending moment, causing curvatures of different sign to arise. The movements of the clamps are controlled by computer, so that the flow regions start at the edge of the workpiece and shift in towards the centre. The dynamics of the clamps can be measured and stored, in order to assist reproduction.

Patent DE-4437718-A1 (DE)
Inventor: MAUS WOLFGANG
IPC: B01D53/86
Filed: 1994-10-21
Abstract: For the catalytic reaction of exhaust gases in an exhaust system, in particular an exhaust system for use in internal combustion engines, a device is proposed with a catalyst carrier element (1) which is provided with a plurality of channels (2) through which the exhaust gas can flow. The free cross section (4) of flow of the channels (2) is partially closed in the direction of flow of the exhaust gas by plastic deformation of the channel walls (11), specifically, in an outer ring region (3) of the catalyst carrier element (1). The plastic deformation can be carried out using, for example, a tool (17) provided for this purpose with a disc (18) which can rotate about an axis (19). The disc (18) is forced against the catalyst carrier element (1) and the casing (10) to create a plastic deformation of the casing tube (10) and channel walls (11) in the form of a peripheral crimp (20) pointing towards the carrier element (1). Other techniques can be applied to create the plastic deformation. The outer channels thus closed off form a thermal insulation against the casing tube (10) which helps the catalyst carrier element (1) to heat up more rapidly in the cold start phase.

Abstract: The drilling test unit views a drilled bore in annular sections in steps with the assistance of a 360 deg. optic, and as a bore development for the further machining, and also reproduced on a monitor screen. The working operation required is carried out by a cleaning device.The cleaning device is cylindrically shaped to contact the drilling wall and passes over the entire length of the drilled borehole. The optic is equipped with a cleaning device.
