Patent DE-3516156-A1 (DE)
Title: Sail-batten trimming system
Inventor: PATERNOSTER RUDOLF
IPC: B63H9/06
Filed: 1985-01-24
Abstract: Sails and airfoils of sea, land and air propulsion means can be aerodynamically trimmed more efficiently by the invention without substantial additional amounts of material and costs. By turning of the mast or mast parts, sail battens, mostly continuous, are pressed by means of lever action from the positive air-pressure side against the sail and are bent in the process so that the desired sail profile is obtained in a very stable form. Here, it is possible to use a specific mechanism or a mechanism which is variable, even during use, so that sail-batten bending and consequently the sail profile can be adapted at any time to the respective requirements. The system can also be designed as a retrofit system; at least individual rig parts of conventional systems can continue to be used. It is decisive that the sail-batten bending and thus the sail profile can also be produced without wind force. The system can be used in both single-layer and multi-layer sails, in groove-guided sails and in sails with mast pockets, in wings for hang gliders and the like. The conversion or the re-designing of a rig with this sail-batten trimming system usually does not infringe the class regulations of the sailing-boat and hang-glider classes, provided that sails with continuous battens are permitted in the first place.

Title: Selection device for circular knitting machine
Inventor: BECK ALFRED
IPC: D04B15/68
Filed: 1985-10-23
Abstract: A circular knitting machine has for each needle 34 a selector 51 with two protruding feet 53 and 54 which each face a selector cam channel 17 and 19 forming part of two superposed selector cams 16 and 18. Each selector 51 is radially pivotably gripped from below by a tip lever 47. The tip levers 47 are each controlled by two selecting sinkers 38 and 72, so that three different tip positions are possible. Accordingly either neither of the feet 53 and 54 of the respective selector 51 dip into a selector cam channel, so that the associated needle 34 remains down, or only the upper foot 54 engages into the corresponding selector cam channel 17, so that the needle 34 is pushed out only to a medium tucking position, or else the lower foot 53 too engages into its selector cam duct 19, so that the corresponding needle 34 is fully pushed out into the knitting position. This design provides a simple and reliable means of controlling three important needle positions without reducing the number of feeds. <IMAGE>

Patent DE-3603073-A1 (DE)
Title: Electronic clock having a weather station
IPC: G04G21/02
Filed: 1986-02-01
Abstract: An electronic clock having a weather station is intended to supply the consumer with a more useful information content for everyday concerns. For this purpose, a clock part (25) is linked to a measuring system (26) for environmental measured values (41) in a functional way to the effect that measured values (41) are determined and stored periodically over a specific predetermined time interval. These measured values (41) are read out sequentially in polling mode from the memory (45) and displayed in a digital or analog fashion (quantitatively or qualitatively). At the same time, instead of the actual time, the clock part (25) specifies, for example, that instant at which the measured value (41) instantaneously read out was recorded. It is possible in this way, for example, for measured values of atmospheric pressure stored hour by hour over a period of 24 hours to be read out and displayed in FIFO mode in a manner synchronised with a rapid stepping of hour display, in order to represent the fluctuation in atmospheric pressure in the past daily cycle against the assigned time, and the actual time and the last-determined measured value (41) are displayed after a rapid double cycle of the hour display (35) - in the example, a point time display. <IMAGE>

Title: Surgical manual instrument for removing tumour tissue
Inventor: FRITZSCH GERNOD DR ING
IPC: A61B18/00
Filed: 1986-07-30
Abstract: In conjunction with an operating device that comprises an ultrasound generator and a liquid aspirator, the manual instrument permits gentle and selective removal of soft pathologically altered biological tissue. The aim of the invention is the creation of an ultrasonic instrument which extends the possibilities for removal of a brain tumour. This is achieved, according to the invention, by the use of a piezoelectric ultrasonic transducer which is mounted with low damping in the vibration node of the manual instrument and which possesses four piezo-ceramic discs and a tapering sound-radiating coupling element of low acoustic impedance. It is releasably coupled to a solid aspiration applicator tapering in a defined manner and having an axial channel starting from the working end which is connected via a radial bore to a suction pipe in the zone of the vibration node. The ultrasonic aspirator is excited in its longitudinal natural resonance. On contact of the biological tissue with the applicator tip vibrating at high frequency small volumes of the tumorous cells and tissues are liquefied and are continuously aspirated through the axial channel of the aspirator (Fig. 3). <IMAGE>

Patent DE-3630386-A1 (DE)
Title: Process and arrangement for cleaning a heat exchanger
Inventor: NASSER GAMAL EL DIN DIPL ING
IPC: F28G9/00
Filed: 1986-09-05
Abstract: The process and the arrangement serve for cleaning a heat exchanger, in which a coolant with a specified rate of flow is pumped through a coolant inlet and a multiplicity of heat exchanger stages with coolant channels to a coolant outlet and in which coolant agent to be cooled is pumped from an inlet via flow agent channels, which are in thermal contact with the coolant channels and are separated from these with respect to the flow, to an outlet. Cleaning agent is supplied in the direction of flow of the coolant from a stage of the heat exchanger to be cleaned, and a corresponding amount of cleaning and cooling agent is removed again after the stage in such a way that the stage to be cleaned undergoes a pressure drop dp2, which leads to a flow rate v2, which is so high that the solids deposited in the coolant channels are carried away. The cleaning of the heat exchanger is carried out in stages, whereby after one stage in the heat exchanger has been cleaned, a stage lying behind it in the direction of flow is cleaned, until a stage in the heat exchanger lying at the coolant outlet is reached, whereupon the cleaning of a stage lying at the coolant inlet is started again.
