Title: Insert lock for fixing curtain runners into tracks - allows smooth high-speed transfer of runners from auxiliary rail via resilient tongues
IPC: A47H13/00
Filed: 1979-11-23
Abstract: The resilient tongues of the lock, in the lower part continue the running face of the guide track and are fastened to the support component of the lock so that they can be moved sideways on either side by pressure from the extension of the guide track whilst maintaining their original horizontal plane. This pressure action can be produced by an upper auxiliary rail section pressed vertically upwards to feed the curtain runners into the guide track and is converted by lower inclined faces on the resilient tongues into a pressure action which moves them horizontally.
Patent DE-2948305-A1 (DE)
Title: Removing mercury vapour from hot waste gases - by finely divided metal which forms amalgam
IPC: B01D53/64
Filed: 1979-11-30
Abstract: The mercury is removed from exhaust gases derived from thermal processes, such as refuse incineration, by treating the gases with metals and/or alloys which form amalgams, i.e. Sn, Zn, Cu, Pb, Cd, U, Ag, Au or Cu alloys such as brass or bronze. The metal should be in finely divided form such as shavings or mesh, and may be the filling of a fluidised bed. If powdered, the metal can be blown into the gas. At the same time separate material may be used to remove harmful acid or alkaline components in the gas. The metal prevents the contamination of the atmos. which occurs with dry systems, or of water with wet systems, which arises when burning, e.g. household refuse, which can contain up to 4 g of mercury per ton.

Title: Double helix screw spindle - has nut provided with double-row ball bearings to double axial load capacity
Inventor: NEESE GERHARD ING GRAD
IPC: F16H25/22

Title: Electrical generator powered by wave motion - has float on vertical guide rising by buoyancy and falling by gravity
Inventor: WEISS GOTTFRIED
IPC: F03B13/18
Filed: 1980-07-21
Abstract: A vertical column is embedded in the sea bed and extends to above the highest level reached by waves. A float of specific gravity 0.5 can move up and down the column on rollers. The float is firmly attached to belts or chains which run over wheels at the top and bottom of the column. The upper wheels are connected by a gear train to a dynamo. The float is raised by the waves and falls by gravity. It takes belts or chains with it and thus drives the dynamo to produce electrical energy.

Title: Central heating system circulation pump switching control - using counter indexed by shutting down pulses for mixer valve
Inventor: LAMBERTI HANS ING GRAD
IPC: F24D19/10
Filed: 1980-08-26
Abstract: The central heating system has a mixer valve (4) adjusted via a setting pulse supplied in dependence on the difference between the actual and required temps. The shutting down pulses are used to index a counter, reset by the opening up pulses, with the circulation pump (5) switched off when a predetermined count value is reached and switched back on again by the next opening up pulse. The burner for the central heating boiler (1) may be shut-down when the circulation pump (5) is switched off. Pref. a module N counter is used, having a divisi on factor of N, its reset gate receiving the opening up pulses via an OR gate. When the count reaches the full value the counting input is switched to the output to provide a continuous pulse, maintained until the counter is reset.

Title: Rotary lawn-mower with centrifugal fan - has extended volute chamber to direct grass cuttings into grass box
Inventor: KLEVER MANFRED DIPL ING
IPC: A01D43/077
Filed: 1980-12-13
Abstract: The rotary oower driven lawn mower has two diametrically opposite blades (5) mounted on a rotating arm (4). This rotating arm acts like a fan and blows the grass cuttings into the grass box (10). This effect is assisted by a centrifugal fan (6) mounted on the same axis as the arm. The volute casing (8) of the fan is extended to form a spout (15) with its outlet (16) near to the entrance to the grass box. The air issuing from the outlet assists in concentrating the flow of air and grass cuttings in the direction of the grass box. This concentration of the flow is due to the fact that the air flowing from the centrifugal fan is kept separate from the flow from the blades until both flows reach the entrance to the grass box.

Title: Chamber filter press
Inventor: JENNINGES NORBERT
IPC: B01D25/21
Filed: 1981-01-07
Abstract: Liquids containing solid components can be filtered with the chamber filter press. These liquids are waste waters (effluents), liquids containing solid components produced in manufacture etc. The chamber filter press contains a filter cavity (22). This is enclosed by support plates (14). On the insides thereof lie flexible membrane plates (16) and on the insides thereof lie filter cloths (18). The liquid is purified on passing through the filter cloths (18) and then flows away between these and the membrane plates (16). At the end of a continuous filter process, compressed air is introduced between the support plates (14) and the membrane plates (16). These arch inwards and compress the filter cloths (18) with the filter cake situated in between. As a result, additional liquid is expressed from the latter.   <IMAGE>

Title: Device for feeding pressure medium from a fixed housing into a shaft mounted in the housing
Inventor: HIESTAND KARL
IPC: B23B31/30
Filed: 1981-01-17
Abstract: In a device (11) for feeding pressure medium from a fixed housing (12) into a shaft (13) mounted in the housing (12), with a sealing ring (14) inserted between housing (12) and shaft (13) and provided with bores (21, 22) interacting with transfer grooves (19, 20, 23, 24), rolling bodies (15, 16) which roll on the shaft (13) and the housing (12) being arranged laterally next to this sealing ring (14), the sealing ring (14) is centred by means of rolling bodies (33, 34) supported on the sealing ring (14) and the shaft (13) and/or the housing (12). This defined bearing arrangement of the sealing ring (14) ensures that the sealing ring (14) is always exactly guided and cannot shift radially if the pressure of the pressure medium changes. The sealing gaps (21, 28) therefore retain the preset values, and pressure-medium transmission working trouble-free over a longer operating period is guaranteed. <IMAGE>

Title: Manually operable balance
Inventor: HAACK WERNER
IPC: G01G1/36
Filed: 1981-05-27
Abstract: A manually operable balance has only a single operating member (14) which can be rotated into two positions. In one position (arrow 36), a rapid motion is switched on and displaces the sliding weight (8) very rapidly via a recirculating ball screw. In the other axial position of the setting knob (14) (arrow 48), a reduction gear (20, 21, 22, 24) takes effect and the sliding weight (8) is displaced more slowly. An indicator device has a counter with two groups of number rollers. Between the roller groups is located a planetary gear having two movement inputs and one movement output. The latter is connected to the thousands roller which is rotated directly by the planetary gear via a secondary shaft (31). A main shaft (34) rotates simultaneously and rotates the units roller, by which the tens roller and by this, in turn, the hundreds roller are advanced. In the number position 999, an actuating pin overrides the planetary gear for the thousands roller. The single manual-operation knob (14) can be rotated in both directions. The balanced state can be found in both directions of rotation. <IMAGE>
