Filed: 1992-03-05
Abstract: A ceramic heating pipe 10 for electric heating of an industrial furnace, is formed so that the inner space of the heating pipe can be placed under an inert (nitrogen or argon) gas pressure. Gas may be supplied from both ends of the pipe. The pipe is of porous nature to allow gas to exit via its surface and protect the pipe from the effects of the heated material. Additional slots may be provided to increase the gas flow to effect as a gas supply to the furnace. Alternatively the pipe may be glazed to reduce gas flow. <IMAGE>
Patent DE-4210056-A1 (DE)
Inventor: LINGENHOELIN DIETER
IPC: F16J1/08
Filed: 1992-03-27
Abstract: The invention concerns an internal-combustion engine reciprocating piston with bosses which are designed to hold the gudgeon pin and which are stepped in the longitudinal direction, thus giving, in the zone extending towards the piston crown, a smaller distance between bosses than in the zone facing the piston shaft. Located in bores in the bosses are lubrication grooves (5) running parallel to the axis of the bores. The aim of the invention is to improve the lubrication inside the boss bores. This is achieved by virtue of the fact that the ends of the lubrication grooves (5) in the boss material, in the step zone between the narrower upper section of the gap between the bosses (1) and the wider lower section of the gap, face towards the crankcase space, i.e. they are separated radially with respect to the gudgeon pin.
Patent DE-4211509-A1 (DE)
Title: Baling press for waste material such as paper, packaging etc. - has rear wall of filling chute driven towards front wall by scissors mechanism to pre-compress waste during working stroke of ram
Inventor: HERMANNS RAINER
IPC: A01F15/10
Filed: 1992-04-06
Abstract: The rear wall of the fitting chute is formed as a pre-compression plate (15). The plate is driven towards the front wall (14) of the chute by a hydraulic cylinder and scissors mechanism (19,22), thereby pre-compressing and reducing the volume of the walls material before it is admitted to the baling chamber. Pre-compression takes place during the working stroke of the press ram (5). Fastened to the rear of the ram head is a plate (12) which acts as a shutter preventing waste material from falling into the space behind the ram. The return stroke of the ram does not extend the full width of the filling chute but only as far as the pre-compressed width of the waste material. ADVANTAGE - Improves press performance and utilization.

Title: Filling up of liquid container esp. motor vehicle oil tank - filling to level measured by dip stick, inserting suction stick and withdrawing fluid until air is detected by light barrier
Inventor: HUETTINGER HANS
IPC: F01M11/12
Filed: 1992-05-05
Abstract: The tank (1) is filled with liq. so that a liq. level is produced, at least slightly above a desired liq. level (2) lying between a min. mark (4a) and a max. mark (4b).

The suction opening (7) of the suction unit (5) lies at the height of the desired liq. level (2). Liq. is sucked from the tank until it is identified that the suction unit (5) is sucking air. This air esp. in the form of bubbles can be identified optically esp. using a light barrier (12). USE/ADVANTAGE - Suitable for mass produced vehicles before delivery of vehicle from mfg. site. Liquid tank can be simply and reliably filled to exact level.

Title: Cold process working cycle for refrigerator
Inventor: KNAPPE OTFRIED DIPL ING
IPC: F25B1/00
Filed: 1993-03-22
Abstract: The cycle for a cold process has the gaseous superheated working medium (point ZP1 on the enthalpy-pressure diagram) brought to condensation pressure and condensed at constant pressure (point ZP2 on the phase diagram). The condensate is reduced in pressure (point ZP3) and then evaporated at constant pressure (point ZP4), and finally brought back up to condensation pressure (point ZP2). The reduction in pressure for the condensate is done in two stages, the first reduction being to a pressure (point ZP5) roughly midway between condensation and evaporation pressures where preferably half of the maximum possible vapour content has been produced. At this stage, the vapour produced is removed at constant pressure and separately brought back to condensation pressure.

Title: Welding-cable connection for manual and automatic arc welding and cutting torch
Inventor: BUERKNER GUNNAR DR
IPC: B23K9/32
Filed: 1993-07-28
Abstract: The welding-cable connection according to the invention is characterised by a socket/contact-pin connection which rotatably and securely attaches the welding cable in the handle of the manual arc welding and cutting torch or to the machine side of the automatic arc welding and cutting torch. The rotatability is ensured by the arrangement of a spring basket (9) in the contact area (8) of the socket. When the contact pin is connected to the socket, the contact area (1) of the contact pin is clamped in the spring basket (9) and is protected from possible withdrawal by means of a clamping spring (13) which engages in an annular groove (4) on the contact pin. The stop (12) arranged on the socket limits the rotatability of the welding cable in interplay with the guide pin (5) arranged on the contact pin and thereby protects the control lines. <IMAGE>
