Title: Two current modulation of semiconductor laser - with higher current in bit stream form and lower current modulated so that sum has approximately constant power
Inventor: PETERMANN KLAUS DR ING
IPC: H01S5/062
Filed: 1980-02-15
Abstract: The total current, I, flowing through the laser comprises two components, (I1,I2). I1 is smaller than the maximum current the laser will carry and is modulated at a frequency which is lower than the reciprocal of the thermal time constant of the laser. The second current (I2), is a bit stream with pulse lengths smaller than the thermal time constant of the laser. I1 affects the temperature in the active zone of the laser whereas I2 is too short to significantly affect it. The wavelenth, lambda, along the emission axis is temperature dependent and the modulation of I1 is at least delta lambda (2 laser cycles). I2 is selected so that the median laser efficiency value remains constant. Therefore the total current I = (I1 + I2) is approximately constant for all bit stream outputs. I1 is typically modulated with 10 to 100 kHz.

Title: Double chamber pasty prod. dispensing package - has vessels inside pressure chamber, burst in stages to release pressure medium to empty bag inside
Inventor: KIEBER LOTHAR
IPC: B65D83/14
Filed: 1980-06-18
Abstract: The barrier-pressure-pack has an outer casing (1) enclosing a flexible bag (3) containing a product to be dispensed through a nozzle (2). It has a space (4) between the bag and the casing forming a pressure chamber which forces the contents from the bag. This space houses ampoule shaped containers (7,11) at top and bottom, which contain a pressure medium which is released, as the contents are forced from the bag. These containers are designed so that certain containers (e.g. the upper containers) burst open to release the pressure medium before other containers burst, so as to maintain a constant discharge pressure as the bag shrinks. This medium can extract heat so that the product, such as a sunburn treatment cream, is cooled as it is discharged. This effect can be obtained by reaction with a substance inside the pressure chamber.

Title: Carburettor ventilation valve with electrical actuator - for preventing fuel leakage due to pressure rise when engine is stopped
Inventor: NIED KLAUS
IPC: F02M5/08
Filed: 1980-12-19
Abstract: Ventilation of the float chamber and of the idling mixture chamber is employed to prevent fuel leakage into the engine. This can occur when the engine is stopped, and due to heating, the pressure in the carburettor rises. The present proposal is to use one electrically operated actuator to open the necessary vents. The idling mixture chamber (1) is connected by a vent pipe (5), of large cross sectional area compared with the air inlet port (2), to a valve (6). The actuator (9) for operating the vent in the float chamber (8) also operates the valve (6) in the idling mixture vent pipe. In one version both the vent pipe from the idling mixture chamber, or pipes if there are several such chambers, and the float chamber vent are all opened to atmosphere by a common valve (6). The design reduces the number of components and employs only one actuator.

Title: Carrying bar for containers
Inventor: HEINRICH SIEGFRIED
IPC: B65D25/28
Filed: 1981-05-15
Abstract: For portable containers having an outwardly projecting edge (16), for example transformer housings, a carrying bar (10) is provided, having limbs (28) which are formed on both sides of a handle (26, 26) and whose ends can be connected to the container in a positive-locking manner. The carrying bar (10) is subdivided into two sections (24) which each have one of the limbs (28) and part (26) of the handle and can be pushed together in the longitudinal direction of the handle. The possibility is thus provided of placing the two sections (24) of the carrying bar (10), which have not yet or only partially been pushed together, against the container from two opposite sides in such a way that they engage on or directly below the edge of the container. If the two sections (24) of the carrying bar (10) are pushed further or completely together, they hold the container between them in the manner of tongs. A catch or clamping connection prevents the two parts (26) of the handle being pulled apart unintentionally. <IMAGE>
Patent DE-3120423-A1 (DE)
Title: Mine layer
Inventor: HOFFMANN ERNST DIPL ING
IPC: F41H7/10
Filed: 1981-05-22
Abstract: In known mine layers, the mine holes are made either by spade-like digging devices or by means of ploughs. But if the ground is hard or even stony, these mine layers can no longer be used. The mines therefore have to be laid in the open. Moreover, the disadvantage of plough-like devices is that they are exposed to considerable bending moments as a result of the load exerted on them, together with the linkages which connect them to the respective mine transport vehicle. Furthermore, in the known instances, there are no possibilities of levelling the terrain again for camouflage purposes after the mine laying. Now the invention provides the precondition, in the form of a boring implement or within the framework of a breaking-open device with a knife-like precutter, for ensuring that individual mine holes or mine trenches can be made in relatively hard ground. For this, one embodiment of the invention provides a boring implement (45) which makes the mine holes in mutual interaction with a mine store (25) automatically ejecting the primed mines (4) to be laid, the drilled-out soil material being collected and, after the mine laying, being distributed uniformly again by means of a levelling device (41, 47). In another embodiment, the ground is cut open by means of a precutting knife (64), a wedge-shaped breaking-open implement (65) then penetrating into this gap, making a trench (71) and depositing the soil laterally. The discharge ramp (28) of the mine store (25) opens into the ground breaking-open implement (65). The ground breaking-open implement (65) is followed by a levelling device (69) which pushes the soil over the trench (71) again and levels the terrain. Both solutions of the invention work fully automatically and are assigned to a mine transport vehicle (2) directly or indirectly in the form of a trailer. <IMAGE>

Title: Device for selecting originals not worth copying in a photographic printer
Inventor: STEIN WERNER VON
IPC: G03B27/46
Filed: 1981-07-03
Abstract: Contained in the photographic printer is a device for selecting originals not worth copying, which are combined in accordance with a multiplicity of jobs to form a long strip. Provided on the strip are marks which characterise the position of the images and the beginning of the originals belonging to a job. Moreover, a film splice scanner (16), a notch scanner (17) of the original strip (1) and a quality detection scanning unit (18) are arranged on the transport path of the original strip (1) upstream of the copying station (4). The quality detection scanning unit (18) can be switched on and off by a selection logic (20) or be switched over to response thresholds of different sensitivity, specifically either on the basis of a pulse from the film splice scanner (16) or of a pulse from a counter (19), inserted between the notch scanner (17) and the selection logic (20), after a settable number of image marks before or after a job end mark, or of the detection of a first image worth copying inside a job. It is thereby achieved that the pictures for no-load switching are reliably detected at the start of a film, whereas the selection device is ineffective in the main part of the film or has an insensitive response threshold. <IMAGE>
