Title: Telescopic suction tube for vacuum cleaner - secures inner tube to outer by relative rotation, inner tube wall having indented arrest recesses working with arresting element
Inventor: SCHULTZ WILFRIED
IPC: A47L9/24
Filed: 1991-01-16
Abstract: The securing body can be held down in the arrest position by a manually operable locking component or freed in an unlocking position. Movement of the locking component is against spring force, the spring, in company with the securing body and the locking component, being fitted in a ring space formed by an outer tube end widened section between the outer and inner tubes, and on a guide casing non-rotatably fitted on the outer tube. There are two unlocking positions (E1, E2) for the locking component (7) on the guide casing (8) which are operable from a common central position of the component. This central position is formed as arresting position (R) for holding down the arresting element (6). The locking component is fixed in its central position via two springs (11, 12, 11', 12') engaging on opposing ends of the arrest fillet. ADVANTAGE - Outer and inner tubes are easily secured or freed as required.

IPC: B66F9/12
Filed: 1991-02-13
Abstract: A warehouse stacker with two liftable load supports (13, 16) which can be separately controlled is of portal type of construction and is provided with two lift frames (12, 15) which are arranged one behind the other in the travel direction and are preferably designed as side lift frames. One lift frame (12) is fastened to the front-end chassis leg (4) of the transverse portal (5) of the vehicle chassis (1). Suspended on the latter is the first load support (13) which is provided with a layer-receiving device (18) for taking hold of at least one goods layer (34) in a layer-receiving position located outside the transverse portal (5). The lift frame (15) of the further load support (16) is arranged suspended in front of the transverse portal (5) and can be pivoted beyond the side of the stacker contour remote from the portal opening. The front chassis leg (3) lying between both load supports (13, 16) is of a flat type of design with a low height. The layer-receiving device (18) of the first load support (13) with a received goods layer (34) can thereby be brought essentially within the longitudinal contour of the stacker in a congruent manner over a load-supporting device (17) of the further load support (16) on which a warehouse pallet (41) is located. The compact type of construction permits efficient warehousing even under restricted space conditions while simultaneously relieving the physical strain on the warehouse worker. <IMAGE>

Title: Intercooler for two=stage compressor - uses temp. sensors and control circuit to open valve allowing spray of condensed fluid between compressor stages
Inventor: KAMMHOFF KARL-FRIEDRICH
IPC: F25B1/10
Filed: 1991-08-22
Abstract: The intercooler circuit for a two stage compressor (1) has the driving motor (4) between the LP and HP stages (2,3).

This taps off from a point between the condenser (5) and the expansion valve (6) and feeds into the compressor just after the LP stage. If the temp. either at entry to the motor or at exit from the HP stage exceeds a threshold, the intercooler valve is opened to allow an amt. of cold condensed fluid to be sprayed into the hot compressed gas after the LP stage. ADVANTAGE - Regulated intercooling independent of fluid used to give required exit temp. at HP stage.
