Patent DE-3219796-A1 (DE)
Title: Control device for the periodic control of a gas or liquid flow
Inventor: MESSMER HANS-PETER
IPC: F01L7/06
Filed: 1982-05-26
Abstract: The invention relates to a compression control system for heat engines with a time sequence of the gas states (piston engines), the combustion chamber or heat exchanger of which contains considerably more working gas than the throughput per revolution, the change in compression being effected exclusively by a change in the gas volume (not the mass) removed from the combustion chamber or heat exchanger per revolution by the relief device. This change in the volume removed is here preferably accomplished by means of a control element which controls the gas volume flowing through by the duration of its opening, with the result that an equilibrium at a new pressure level is established. By appropriate modification of the volume removed by the relief device, it is possible in heat engines to ensure that, in the case of throttling of the load, i.e. a reduced gas supply by the compressor or reduction of the gas temperature in the combustion chamber or heat exchanger, the compression remains constant. The matching of the machine to the knock properties of different types of fuel is furthermore possible.

Title: Method for determining the angle of the normals of a specimen rotating about a fixed axis of rotation and measuring machine for carrying out the method
IPC: G01B11/26
Filed: 1982-09-07
Abstract: In a method for determining the azimuthal angle of the normals to a specimen rotating about a fixed axis of rotation, use is made of a light beam which falls upon a light detector in accordance with the respective azimuthal angle of the specimen. The light beam has a small aperture angle and a small cross-sectional area and is emitted in a manner intersecting the axis of rotation of the specimen. The arithmetic mean is formed from two adjacent azimuthal angles at which there is in each case a variation in the intensity of the light beam, i.e. a lightening or darkening of the light beam, and this mean represents a measure of the azimuthal angle of the normals.

Title: Sealing device for a continuous linear passage of containers
Inventor: LIPOWSKI HELMUT
IPC: B67C7/00
Filed: 1983-01-22
Abstract: The invention relates to the sealing of containers with smooth or otherwise profiled edges. The aim of the invention is to make sealing possible when there is a continuous linear passage of containers with a high throughput of containers. To this end it is necessary for feeding of the seals to the container and the sealing process to coincide in time and space. The device comprises two plates which are provided with recesses for reception of the containers and which in the closed state move synchronously with the transport belt, whereas their return movement is slower and is possibly even interrupted to relieve acceptance of the seals by the magazine, which is fixedly connected to the framework. The seals are mounted in transfer discs which assume the task of positioning above the sealing points under the sealing units which are also attached to the plates. Additional processing of the seals can occur during rotation of the transfer discs. The transport belt speed remains constant. Possible areas of application are the food and drinks industry.

Title: Contact system for single-column pantograph interrupters
Inventor: FRIEBE HARRY
IPC: H01H31/36
Filed: 1983-02-28
Abstract: In a contact system for single-column pantograph interrupters, main-current contacts (2, 4 and 5) are provided which consist of moving pantograph contact pieces (4, 5) and the stationary mating contact piece (2). These main-current contacts (2, 4, 5) can be connected in parallel with preliminary contacts (14) which consist of a stationary preliminary contact piece (14a) and moving preliminary-contact pieces (14c). The preliminary-contact pieces (14c) close before the main-current contacts (2, 4 and 5) during switching on and open after the main-current contacts (2, 4, 5) during switching off. In this case, the stationary preliminary-contact piece (14a) is rigidly connected to the mating contact piece (2). In order to be able to carry out the switching movement of the preliminary-contact pieces considerably faster than that of the main-current contacts, the moving preliminary-contact pieces (14c) are constructed as two-armed levers which are supported in an electrically insulated manner and such that they can pivot on the mating contact piece (2), and are spring-loaded in the switching-off direction. The one lever arm (14b) of the moving contact pieces (14c) can be operated by in each case one of the moving pantograph contact pieces (4, 5). The other lever arm (14c) carries a contact element (16) for engagement with the stationary preliminary-contact piece (14a). <IMAGE>

Title: Visual signalling device which can be actuated by customers in order to call for service in restaurants
Inventor: KLEINERMANNS HUBERT
IPC: G08B5/00
Filed: 1983-05-26
Abstract: The device stands on the customers' tables in restaurants. It offers the customer the facility of issuing at any time a visual signal by a simple manipulation of the device, this signal being easily perceived by the service personnel even from a substantial distance. The device can consist, for example, of a vertical rod projecting from a baseplate, on which rod a visually striking sliding sleeve can be moved up and down, this being retained at any height on the rod by friction. If the customer requires service, he moves the sliding sleeve from the lower end of the rod upwards to the top, where it is automatically locked. The service personnel can now perceive this visual signal from a substantial distance and attend at the table in question. The movement of the sliding sleeve to half the height of the rod can represent the signal "bill, please". The device releases the customer from the previous irritation of watching out for and calling the service personnel.
Patent DE-3320340-A1 (DE)
Title: Liquid phosphate-free detergent
Inventor: PAASSEN NICOLAAS ADRIANUS IGNA
IPC: C11D3/386
Filed: 1983-06-04
Abstract: Hitherto, complicated substance systems have been added to enzyme-containing detergents to stabilise the enzyme, but they do not contribute to the washing effect. It would therefore be a great advantage if there were surfactants with a stabilising effect on enzymes. This is actually the case with ether carboxylic acids. The invention therefore relates to a liquid phosphate-free detergent which contains a salt of an ether carboxylic acid as enzyme stabiliser.
