Title: Picture tube holder for television receivers
Inventor: GEELHAAR BERND
IPC: H04N5/645
Filed: 1981-09-01
Abstract: To mount the picture tube of a television receiver, the inside stiffening ribs of a plastic housing front part at the four corners of the housing front part in each case support a socket which accommodates a mounting bolt for the picture tube. To save material and work, the socket (2), according to the invention and Figure (1), is constructed of two U-shells (5, 6) interleaved with one another at a distance, which together form an insertion channel, which is reversely T-shaped in section, for a head bolt, which accommodates the laterally inserted head bolt (3) with a snapping action. This avoids bonding-in by means of plug-like intermediate pieces or screwing-in of mounting bolts and saves material and work. <IMAGE>
Patent DE-3135037-A1 (DE)
Title: Discharge pump
Inventor: HERTELL SIEGFRIED DIPL ING
IPC: F04C15/00
Filed: 1981-09-04
Abstract: The invention relates to the sealing of the shaft journal (9) of a discharge pump, especially a gear pump for molten polymers. Sealing is effected by means of a barrier fluid which according to the invention is a solvent for the polymer and is passed, at a slight positive pressure, into an annular cavity (27) which surrounds the drive-side shaft journal (9) and in an axial direction is bounded on both sides by stuffing-box packings (17, 18) held at a distance by spring elements (20). Owing to this design of the discharge pump, the inevitable leakage of the polymer delivered at high backpressure and high temperature is limited, and solidification, which impairs the sealing effect of the stuffing-box packings (17, 18) and makes them ineffective, is prevented. The barrier fluid can be circulated in a circuit consisting of reservoir (24), down main (32) and rising main (31), and be cooled and monitored at the same time. Further proposals relate to avoiding stagnation of the melt in chambers with reduced melt flow and the pressure relief of the bearing casing (10, 10.1) by a relief duct (16) connected to the suction side (5) of the pump, and by an inverse gap control to reduce friction and wear on the lateral faces of the gear wheels. <IMAGE>

Patent DE-3214491-A1 (DE)
Title: Oil-feed device for a controllable-pitch propeller
Inventor: WUEHRER WOLFGANG DIPL ING DR
IPC: B63H3/08
Filed: 1982-04-20
Abstract: Mounted on an intermediate shaft (13) connected to the propeller shaft (6) are a fixed housing (18) and separating rings (36a, 36b, 36c) which define in the housing (18) two annular passages (38 and 39) to which pressure oil can alternatively be admitted. Via control passages (60 and 61) which pass through the intermediate shaft (13) and the propeller shaft (6), these annular passages (38 and 39) are connected to two working spaces of a servomotor of the controllable-pitch propeller, which working spaces can each be loaded in opposite directions of action. The separating rings (36a, 36b, 36c) are each designed in one piece in the peripheral direction and, by web sections (41) flexible in the radial direction, are firmly connected in the axial direction to the separating ring (36a, 36b, 36c) allocated to the same annular passage (38 or 39). Each separating ring (36a, 36b, 36c) is guided in a sealing manner in a cylindrical bore of the housing (18) by a sealing strip (37) projecting beyond its outer peripheral surface. This arrangement permits elastic deformations of the separating rings (36a, 36b, 36c) for narrowing the bearing gap formed with the intermediate shaft (13), the sealing effect of which bearing gap is thereby improved, and permits a one-piece design in the peripheral direction of the housing parts (31, 32, 33) which surround the intermediate shaft (13) and thereby require less machining and assembly effort. <IMAGE>

Title: Hydrodynamic eccentric-spiral machine
Inventor: STREICHER MAX
IPC: F01C1/107
Filed: 1982-08-21
Abstract: In the eccentric-spiral pump, the axis (15) of the rotor (2) revolves around the pump axis (12) in the stator (1), which is divided by stator discs (103), as is the rotor by rotor discs (122), into pump stages with the stage width (b). In order to close off leakage openings in the parting planes between adjacent pump stages, screening means are provided, for example alternate radial changes in circumference with axially adjoining engagement surfaces which are provided on separate parts or on the same part, for example stator cavities (34 and 134) or sintered surfaces (221 and 121) with half the stage width b DIVIDED 2, separated by shoulder surfaces (51). The overlaps at the shoulder surfaces (51) prevent leakage flows and thereby make possible the pumping of low-viscosity media at relatively high pressure. <IMAGE>
Patent DE-3233081-A1 (DE)
Title: Simple trough-shaped mirror collector
Inventor: RADONS ULRICH
IPC: F24S23/74
Filed: 1982-09-06
Abstract: The collector according to the invention is for the recovery of solar energy in the lower to middle temperature range. It can preferably be used for hot water preparation and for house heating. The usual flat collectors for this use range have large heat losses because of their large-surfaced absorbers. Trough-shaped mirror collectors described in the literature indeed reduce the heat losses in proportion to the heat radiating in, but are expensive because of their costly shaping and do not generally offer sufficient space for an additional vacuum insulation (Fig. 1). In the mirror collector according to the invention, the shaping is simplified, in contrast to the known systems, by flattening of the trough shape, and additional space is provided for adding a vacuum insulation (Fig. 2). With a concentration ratio according to the invention smaller than 2, this collector offers excellent acceptance of direct solar radiation. Considerable acceptance for diffuse radiation is also achieved. Radiation measurements and heating simulation computations have shown that with the mirror collectors according to the invention, solar houses can be built in Central Europe which are fully self-sufficient in heating and are also affordable. <IMAGE>

Patent DE-3316087-A1 (DE)
Title: Sewer suction and flushing vehicle
Inventor: LANCIER AUGUST
IPC: E03F7/10
Filed: 1983-05-03
Abstract: The sewer suction and flushing vehicle relates to a suction-cleaning and/or high-pressure-cleaning installation of a flushing vehicle. Switching of the high-pressure water pump or suction pump of the vehicle is now no longer to take place on the vehicle itself (e.g. stop-cock or pressure-regulating valve), but directly from the remote operating point. Independent switching of the high-pressure water pump and suction pump is thus possible without significant delay with a single operator. Here, provision is made for the sewer suction and flushing vehicle to be provided with a suction-cleaning and/or high-pressure-cleaning installation of this type, in which the water high-pressure pump or suction pump are switched on and off by the action of an electropneumatic convertor remotely controlled by an electric switching circuit, a hydraulic or pneumatic cylinder acting on a push-in coupling between sewer vehicle motor and water high-pressure pump or suction pump. High-pressure water pumps or suction pumps can thus be controlled at high power, independent switching of these pumps combined with a robust operation not prone to faults, being possible. <IMAGE>
