Patent DE-2918273-A1 (DE)
Title: Closed tilt and sliding door security mechanism - has rebate stop plate, bolting stem on drive rod, and push bolt linked to rod (OE 15.5.79)
Inventor: AMANN ANTON
IPC: E05B65/08
Filed: 1979-05-07
Abstract: The device is for preventing a sliding door unit from tilting, where the door wing, with drive rod, is tiltable in the closed position. The rod, on the vertical wing rebate, slides down into an unbolting position, and then into a tilt position, releasing a scissors mechanism. The vertical rod (4) incorporates a parallel bolting stem piece (7). A stop plate (20) in the stock frame rebate works in conjunction with this, engaging it in the locking position of the rod, and releasing it in the unlocking position. There is a push-bolt (8) drive-linked to the rod, engaging behind a safety stop (22) on the bottom stock frame shank (21) relative to the movement direction of the wings. This is simple, readily built into a rebate, and operable in conjunction with standard drive rod fittings.

Title: Container produced by bottle pack process - has moulded closed tubular stub with rubber tube forming bleeder valve
IPC: B65D1/12
Filed: 1979-07-10
Abstract: In the upper zone of a container, a projecting tubular sealed stub is formed during mfr. The wall of its shaft can be pierced, and when an elastic tube of rubber is slipped over it under tension, it forms a vent valve. The container is of thermoplastic material and is produced by the "bottle pack" process; a combined blow moulding and filling process in which the liq. filling is put in under pressure. The cover welded to the screwed neck of the container can easily be removed. Some media such as bleaching liquors may overload an ordinary container stored in a relatively high ambient temp., and this problem is overcome by the venting valve.
Patent DE-2933574-A1 (DE)
Title: Deep drawing sheet metal - coated with self adhesive protective polyethylene film with specified properties
Inventor: MOSER STEFAN DR
IPC: C10M107/04
Filed: 1979-08-18
Abstract: Deep drawing sheet metal with a self-adhesive protective surface film uses polyethylene for the latter. The chosen plastic has the highest possible restoring force at a given elongation and has a relaxation of at least 50% of the elastic proportion within one minute after the deep drawing operation, thus resembling the behaviour of plastified PVC. This can be applied in a much smaller thickness and at a lower cost than PVC and requires neither plasticiser nor release coat.

It is now easy to remove this rail section together with all the curtain runners when the curtains are to be cleaned. The length of the removable part should be adequate to take all the curtain runners without undue crowding. The system is designed for simplicity of assembly.

Title: Frequency and phase control for plesio chronic oscillator - has phase totals counter retaining contents even if reference phase fails briefly
Inventor: SETTFORS JAN DIPL ING
IPC: H03L7/087
Filed: 1979-10-09
Abstract: The control has two phase discriminators (Ph1,Ph2) comparing the oscillator's (OSZ) output with a reference (Ref). The outputs of both discriminators control a phase totals counter (PSZ) that counts 360 deg. phase movements. A correction pulse is passed to a frequency correction counter (FKZ) during every count event of the phase totals counter when the direction of the frequency difference is i.e. when the oscillator phase moves away from a reference and suppresses a correction pulse when the direction of the frequency difference is i.e. when the oscillator phase moves towards the reference phase.

Title: Friction clutch
Inventor: HOENEMANN RUDOLF
IPC: F16D23/14
Filed: 1981-04-03
Abstract: The invention relates to a friction clutch which can be activated via a disengagement system for optional rotationally-fixed connection or disconnection of an engine and a gear. For simpler assembly and disassembly of the engine/gear units, the disengagement system is subdivided into two components, these being pre-fitted on the one hand on the gear side and on the other hand on the engine-side clutch prior to assembly of the engine/gear units, and being connected positively or non-positively via a lock connection upon assembly of the engine/gear units. The lock connection is in this case designed in such a way that it can be released in the assembled state of the engine and gear units in order to disconnect the two units of the disengagement system pre-fitted on the one hand on the gear side and on the other hand on the engine side and to permit, in this way, the disassembly of engine and gear.

Title: Circuit arrangement for shutting down electronically controlled diesel injection systems
Inventor: ROTHE JUERGEN DIPL PHYS
IPC: F02B3/06
Filed: 1981-04-10
Abstract: The invention relates to a circuit arrangement for shutting down electronically controlled diesel injection systems, especially as a function of the engine speed, in order to avoid inadmissibly high speeds. The object of the invention is to create a circuit arrangement which enables diesel engines with an electronically controlled injection system to be rapidly shut down should inadmissibly high engine speeds occur. This object is achieved in that a pulse generator driven by an engine delivers a sequence of pulses with a frequency varying as a function of the speed, which frequency is available as a measure of the actual speed. By means of a digital-analog converter this sequence of pulses is converted into a d.c. voltage proportional to the speed, which, when an adjustable limit value is reached, interrupts the injection process and shuts down the diesel engine. The application is mainly in higher-power diesel engines, which are used as main or auxiliary engines in ships.
