Patent DE-2845110-A1 (DE)
Inventor: EHRMANN WOLFGANG ING GRAD
IPC: E05C19/06
Filed: 1978-10-17
Abstract: A lock catch for doors having holding elements thereon includes a catch housing formed with at least one door-mounted holding element-receiving slot therein. At least one locking lever is pivotably mounted within the catch housing. A spring is positioned within the catch housing to normally bias the locking lever to project into the slot. A first bevelled surface is formed on the locking lever and is engageable by the holding element on the door when the door is closed, such engagement resulting in pivotal movement of the locking lever in a first direction to permit entrance of the holding element into an inner end region of the slot inwardly of the locking lever. A second bevelled surface is formed on the locking lever is engageable by the holding element of the door upon withdrawal of such element from the inner end region of the slot in which it has been locked releasably. Such engagement effects pivotal movement of the locking lever in a second and different direction to permit withdrawal of the holding element from the slot. The spring is so positioned relative to the pivot axis of the locking lever and the bevelled surfaces thereof that the effective lever arm of the locking lever when the first bevelled surface is engaged by the holding element entering the slot is greater than the effective lever arm of the spring acting on the locking lever. Further, the effective lever arm of the spring acting on the locking lever is greater than the effective lever arm of the locking lever when the second bevelled surface is engaged by the holding element during withdrawal of the holding element from the inner end region of the slot.

Title: Mine coal cutting pick cone fixing lug - has reverse cone and circular sections, and reducing collar on ledge
Inventor: WETCHEWALD KARL-HEINZ
IPC: E21C35/18
Filed: 1978-10-27
Abstract: The pick is used esp. on mineral extracting or forward-driving machines in underground mining. The shaft and head of the pick are circular in cross-section, and a fixing lug on the cone is inserted in a hole on the end of the head, with solder in an annular gap. There is a reducing collar (2) between cone (3) and lug (4), set on a ledge (8). The lug comprises a section (11) attached to the collar, of inverted cone shape, and a cylindrical section (12) attached to it, and it fits the lug hole (5). An intervening peripheral soldering-medium gap is cut out, with the reducing collar seated on the ledge. This prevents the fixing lug from becoming prematurely detached from its hole during pick operation.

Title: Toggled injection mould - operated by low energy hydraulic system with controlled and other valves plus non-return valves
Inventor: OEHM WOLFGANG
IPC: B29C45/68
Filed: 1978-12-04
Abstract: An hydraulic system for closing toggled injection moulds consists of a pipe system, non-return valves (some regulated), flow rate and other valves, and accumulators. The oil returning from the closure cylinder chamber via one valve, on control valve, one regulated and one other non-return valve is stored in an accumulator with two chambers, the non-return valves are thereby closed; when the mould is to be closed, the stored oil flows under low pressure via valves, controlled non-return valves and flow rate valves into the cylinder chamber a non-return valve is closed, at the last stage of closure the system changes over to high pressure via a valve the controlled non-return valves are closed and the small quantity of oil remaining in the accumulator is led back into a tank via one controlled and one other non-return valve. Considerable energy savings are obtd. Press cannot be closed if mouldings or sprues lie between the mould tools.

Title: Light fitting frame with removable, transparent coVer - has support elements, each with transverse and vertical stops permitting cover swivel and removal
Inventor: KARLSSON TOR-LENNART
IPC: F21V17/10
Filed: 1979-05-10
Abstract: The rectangular light fitting frame with removable cover has two support elements in either long side. Each L-shaped support (201) works with cross (121) and vertical (122) stops within the main frame. The vertical stop is so spaced (D) from the leg (11) as to that the cover (2) lifts with legs (2011) straight over the rim leg (111). The projection of the supports on the light opening (200) equals the distance (A) between leg and cross stop at maximum opening angle between cover and frame, and greater than (A) at higher angles. The cover forms a louvre whose cross slats (23) lie between two stringer supports (20) with their horizontal legs (2012), with adjoining support leg (2011). The stringers project both ends beyond the final slat, closing off the end of the cover.

Title: Chrominance carrier phase position measuring system - compares coincidence of front flank of horizontal signal with zero passage of processed chrominance carrier
Inventor: TRISSL KARL-HEINZ DIPL PHYS
IPC: H04N17/02
Filed: 1979-05-30
Abstract: The system is intended for a PAL-coded colour TV signal, using the horizontal signal, the chrominance carrier, and the PAL-switching signal. The front flanks of the processed horizontal signal are compared for time coincidence with the zero passages of the processed chrominance carrier. The time coincidences are selected in time intervals dependent on the PAL-switching signal, the intervals corresponding to the interval of four TV lines. The selected coincidences are displayed w.r.t. their position within the TV raster. The used circuit has a detector for the time coincidences, a selector of the coincidence indicating signals from the detector in each fourth line of the TV raster, and a display device for the selected signals at the selector output, related to their time position within the raster.

Title: Phosphorus fertiliser prodn. from steel-making slag - by mixing with sludge from wet-process phosphoric acid mfr.
IPC: C05B5/00
Filed: 1979-06-30
Abstract: Prodn. of a P2O5-contg. fertiliser from waste sludge from wet-process H3PO4 mfr. is carried out by adding the sludge to steel making slag in an amt. such that the dry mixt. contains 3-9% P2O5. The slag is pref. ground before mixing with the sludge, or part of the slag is ground and mixed with the sludge and the rest is added in lump form. The sludge is pref. added to the slag while the latter is still hot, and the mixt. is subjected to forced agitation to produce 0.3-2mm granules which are then ground. The process eliminates problems associated with disposal of the sludge and converts it into a useful product without the need for expensive additives.

Title: Central heating system with electric heat pump - has by=pass for solar collector, controlled by temperature of heat retainer medium
Inventor: PETER ERWIN DIPL PHYS
IPC: F24D11/02
Filed: 1979-09-11

Title: Steering wheel has oscillation about mid-position damped - by magnets on fixed and rotating parts of steering column assembly
Inventor: PFLUGHAUPT ROLF ING GRAD
IPC: B62D1/16
Filed: 1980-01-17
Abstract: The arrangement is intended for eliminating the to and fro swinging movement of a steering wheel (2) about the straight ahead position after steering through a curve or as a result of road conditions or the like. The steering column (4) or a projection (14) fixed thereon carries permanent magnets (18) or magnetisable elements whilst a fixed carrier (12) facing this projection holds magnetisable elements or permanent magnets (16) so that deviation from the straight ahead position is resisted. The magnets, or magnets and elements may be arranged to produce this resistance by mutual attraction or to produce a mutually repelling force which increases with increasing deviation from the mid position of the wheel.
