Patent DE-3152927-A1 (DE)
Title: Flat screen printing machine with moving squeegee unit
Inventor: BREINDL HERBERT
IPC: B41F15/18
Filed: 1981-09-14
Abstract: The flat screen printing machine with moving squeegee unit has a screen which is fixed during the printing operation and is intended for printing rectangular sheets with unequal side lengths of large formats. During the printing operation, the gripper strip can be swivelled away with the grippers below the plane of the baseplate by a device, in which case the sheet projecting over the baseplate is supported on the longitudinal side by a support strip and, when the printing operation has been completed, the grippers can be swivelled up above the baseplate, receive the sheet and transport it out of the machine. It is possible in this manner to move the grippers out of the printing path during the printing operation and to print the sheets in the gripper region as well.
Patent DE-3207695-A1 (DE)
Title: Telephone microphone
Inventor: CONSTANTIN HERMANN DIPL ING
IPC: H04R1/22
Filed: 1982-03-04
Abstract: The arrangement relates to a telephone microphone with an acoustic resonator disposed in front of the diaphragm. The acoustic impedance of the resonator is reduced by means of bores in the speech inlet. The bores are also soundproofed by suitable measures on a large graduated circle at the edge, while the bores disposed on a smaller graduated circle in the centre remain unsoundproofed. As a result, interferences in sound wavelengths in the order of magnitude of the dimensions of the capsule are suppressed and the frequency response decay above the transmission range is positively affected.

Title: Method for preparing dialysis solution for use in haemodialysis equipment, as well as a device for carrying out the method
Inventor: TERSTEEGEN BERND DR MED
IPC: B01F5/00
Filed: 1982-03-30
Abstract: The invention describes a method for preparing dialysis solution for use in dialysis equipment, as well as a device for carrying out the method. For preparation of an individually adapted, physiologically high-quality composition of the dialysis solution it is proposed that the dissolution of the solid substances take place by swirling in a chamber through which water flows. The dialysis solution which consists of water and substances dissolved therein is preferably prepared batchwise in each case in a quantity corresponding to the capacity of the corresponding dialysis equipment in a central supply unit by dissolution of substances, matched to the individual requirements of each particular patient, in water, and the dialysis solution thus prepared is then supplied to the particular dialysis equipment.
Patent DE-3221681-A1 (DE)
Title: Mass spectrometer with an external sample holder
Inventor: BENNINGHOVEN ALFRED PROF DR
IPC: H01J49/04
Filed: 1982-06-08
Abstract: In the mass spectrometer, the sample to be investigated must be vaporised and ionised in order to achieve mass separation with the aid of electrical and/or magnetic fields. A laser pulse is used to vaporise and ionise the sample. The sample is no longer located in the mass spectrometer, as in the past, but is fixed on a thin polymer film and is arranged on the outside of the mass spectrometer at normal pressure (air or protective gas). In this case, the polymer film is constructed as an inlet window to the mass spectrometer space. Using the laser beam, a micro-hole is burned in the supporting film, through which the sample located at this point is vaporised into the mass spectrometer space. The diameter of the micro-hole is so small that the high vacuum in the mass spectrometer is not adversely affected. The invention makes mass-spectrometric investigation of solid samples possible which would decompose or sublimate in a vacuum. In consequence, new application fields for mass spectrometry can be explored. <IMAGE>
Patent DE-3233296-A1 (DE)
Title: Hair-waving device
Inventor: HOFFMANN HARALD
IPC: A45D1/02
Filed: 1982-09-08
Abstract: In a gas-heated hair-waving device, a gas supply valve (3) is adjusted by means of a lever mechanism (7) in accordance with the temperature of the hair-waving device. The setting stroke of the lever mechanism (7) is produced by the fact that a permanent magnet (13) is mounted on a control plate (8) of the lever mechanism (7) and rests against a body (16) when the hair-waving device is cold. If the hair-waving device is heated excessively, the body (16) is heated to above its Curie point, such that the setting spring (14) can press the permanent magnet (13) away from the body (16) and, as a result, the control plate (8) adjusts the gas supply valve (8) in the direction of a closing movement. <IMAGE>

Title: Emergency spectacles with Fresnel lenses
Inventor: SCHOENFELDER THOMAS DIPL ING
IPC: G02C5/00
Filed: 1983-05-17
Abstract: The invention describes emergency spectacles in which the refracting elements consist of Fresnel lenses which can also be dyed. By virtue of a smaller space requirement and weight, the spectacles can be carried along more conveniently as replacement spectacles for emergencies, than can conventional visual aids in the form of spectacles, and this is preferably further promoted by the use of flexible material.

Inventor: IZUMIDA KIICHIRO
IPC: B64G1/24
Filed: 1984-05-12
Abstract: A system for controlling the orientation of an artificial satellite is described. The orientation of the satellite is determined using spatial coordinates and angular speeds of rotation about the body axes of the satellite, and using inertial and stellar sensors. The objective orientation of the satellite is calculated on the basis of the present orientation information, the angular speeds and from orbit information which is received from a ground station. The orientation of the satellite and the rates of change of the orientation are controlled simultaneously.

Title: Mechanical endless connection for a conveyor belt, especially for bucket conveyors
Inventor: KLUEPFEL OLAF DIPL ING DR ING
IPC: F16G3/06
Filed: 1984-05-30
Abstract: In the case of a mechanical endless connection for a conveyor belt, especially for bucket conveyors, in which the two end sections which are to be connected to one another of the conveyor belt section which is to be made endless are bent away outwards at the connecting point, essentially at right angles to the running side of the conveyor belt, after a rounded transition, and mouldings which are connected to one another by means of connecting screws rest on its outside and inside, by means of which the course of the conveyor belt at the connecting point is predetermined, a reinforcing element through which the connecting screws pass being allocated to the outer mouldings on both sides, in each case located outside, it is intended to create a solution which considerably simplifies or renders superfluous the initial connecting screw assembly and its tightening, at a low material cost. This is achieved in that the reinforcing elements are constructed as U-profiles (6, 11) and in that the U-reinforcing profile (6) which is allocated to the heads (9) of the connecting screws (8) is dimensioned in such a manner that the inner surface of a flange (7) of the relevant U-reinforcing profile (6) in each case rests on a screw-head side surface (10) in such a manner that the relevant screw (8) is secured against rotation. <IMAGE>

Title: Device for producing hollow bodies from thermoplastic material by the blow moulding process
Inventor: DINI NORBERT ING GRAD
IPC: B29C49/42
Filed: 1984-08-04
Abstract: In a device for producing hollow bodies from thermoplastic material by the blow moulding process a clamping unit is arranged on a base frame and comprises two mould carrying elements which are movable with respect to one another by means of a hydraulic cylinder and a synchronising device and each carry one mould half. Furthermore, gripper lever arms which carry gripper elements and are synchronised with the movement of the mould carrying elements are arranged on the base frame, the mould halves and the gripper elements closing in a spatially fixed mould-parting plane on account of kinematic coupling.   In order, with direct coupling between gripper elements and mould carrying elements, to reduce deformations of the clamping units, which occur in irregular loading cases and impair the required clamping states, one of the lever arms mounted on the base frame is coupled to a pull and push rod of the synchronisation system (toggle-lever synchronisation system or rack synchronisation system), the synchronisation with the other lever arm taking place via a synchronisation lever connecting the two lever arms.
