Patent DE-3143488-A1 (DE)
Title: Switching device
Inventor: MANN HERBERT ING GRAD
IPC: H01H13/18
Filed: 1981-11-03
Abstract: In a switching device, two mutually electrically insulated contact springs (4) engage between two plug pins (7) of a connecting plug. The plug pins (7) are in this case inserted into holders (16) and have a free intermediate space opposite the contact springs (4). A switch plunger (8) having a conical switch contact (9) engages between the contact springs (4), which switch plunger deflects the contact springs (4) laterally with respect to the plug pins (7) when axial displacement of said switch plunger (8) occurs, until the contact springs (4) make electrical contact with the plug pins (7). The axial displacement of the switch plunger (8) in this case takes place against the force of a spring (10), by means of a depression (15) on a cover (14) which closes a corresponding opening (13) in a chamber (2). An electrical connection of the plug pins (7) to the contact springs (4) thus take place only when the cover (14) is covering the corresponding opening (13) of the chamber (2). <IMAGE>

Title: Container for a salt lick
Inventor: HACKETHAL THOMAS
IPC: A01K5/015
Filed: 1981-11-21
Abstract: The invention relates to a container which is suitable for accomodation of a salt lick and is easily accessible to horses due to its bevelled shape. The lick can be stored in the container separately from the remaining fodder and thus avoids the disadvantages of the previous method where the salt licking stone was placed in the vicinity of the remaining fodder. Separate accommodation of the salt lick avoids mixing of the latter with the remaining fodder or covering of the lick by the fodder. The container can be fastened to a suitable stand or on the wall through the holes provided in the rear wall. The hole in the bottom ensures drainage of any salivation.

Title: Method and device for determining the speed of light-scattering objects such as molecules, small particles or the like
Inventor: SCHMITT FRIEDER
IPC: G01P5/26
Filed: 1981-12-10
Abstract: The subject of the invention is a method and a device for determining the speed of light-scattering objects such as molecules, small particles or the like, at least one light beam being directed onto the scattering centre (10), being scattered there and scattered light (36) being recorded by means of at least one detector (20). Such a method is normally termed Doppler laser anemometry. The known methods operate with a single-colour laser, or only one colour is used for measurement, either the laser beam being split into two beams and a reference beam being split off, or, instead, two beams scattered in different directions being brought into superimposition. In any case, an expensive optical system having, inter alia, beam splitters is required, and these produce sources of error. For the purpose of improvement and simplification, it is proposed to direct light of at least two wavelengths ( lambda 1,  lambda 2) from a multicolour laser (12) onto the scattering centre (10) without splitting. <IMAGE>

Patent DE-3218167-A1 (DE)
Title: Instrument for the introduction of anaesthesia catheters
IPC: A61M16/04
Filed: 1982-05-14
Abstract: The invention relates to an instrument for the introduction of anaesthesia catheters into the larynx and the trachea under visual control using an elongate, bent introduction tube which contains a glass fibre image conductor, the tube being partially encased by the anaesthesia catheter during introduction. In order to design this instrument so as to be much shorter and thus more handy, completely irrespective of the size of the patient, the invention proposes that the introduction tube be designed with at least one at least partial helical turn. As a result, the introduction tube can be kept short completely independently of the size of the patient. In fact, the anaesthesia catheter can be easily guided around the helical turn by the doctor himself, and furthermore the fact that the tube is helically wound does not lead to any reduction in the quality of the image. It is applied in the above-mentioned medical field. <IMAGE>

Filed: 1982-07-07
Abstract: An anti-skid chain for vehicle wheels, which is constructed in particular as a track-cross chain, with a holding ring (1) made of spring steel wire which has an improved hook closure. The holding ring (1) has an end (1a) which is bent around essentially in the shape of a hook for permanent connection to the hook-in sleeve (9) of the hook closure, the adjacent side hook (4a) of the chain network being arranged in a freely rotatable fashion on the holding ring (1) next to the hook-in sleeve (9). The end (1a), attached in the hook-in sleeve (9), of the holding ring (1) is bent over towards the inside of the ring and the hook-in sleeve (9) is constructed in two parts, from a shaft part (9a) which is attached to the holding ring (1) and from a capturing funnel (9b) which is placed thereon for the bent-over releasable end (12) of the holding ring (1). As a result, not only is a particularly simple and durable design of the hook closure produced but also particularly convenient handling results. In addition, the chain network of the anti-skid chain is turnable. <IMAGE>
Patent DE-3226763-A1 (DE)
Title: Means and method for fragrancing the interior of dishwashers
Inventor: KUENZEL WERNER
IPC: A47L15/44
Filed: 1982-07-17
Abstract: The means consists of an at least partially fragrance-permeable container which contains a fragrance-emitting material composed of fragrance and a fragrance carrier. The fragrance carrier is preferably a silicate material modified with organic ammonium salts, through which the fragrance is given off uniformly over a relatively long period. The fragrance-permeable part of the container is covered with a fragrance-impermeable layer which, on initial contact with water, comes off or dissolves. To fragrance the interior of dishwashers, the container is inserted in the interior and the washing cycle is started, as a result of which the means is brought into contact with water and the fragrance-impermeable covering of the means thus comes off or dissolves so that the fragrance slowly escapes from the means through the fragrance-permeable parts of the closed container and diffuses in the washing chamber.
Patent DE-3228922-A1 (DE)
Title: Connection of preferably dynamically highly-stressed machine parts by means of a plurality of long bolts and a plurality of short bolts
Inventor: DESCHLER GERHARD DIPL ING
IPC: F02F1/10
Filed: 1982-08-03
Abstract: The invention relates to a connection of preferably dynamically highly-stressed machine parts, especially the mounting of the cylinder head on the crankcase, by means of a plurality of long bolts and a plurality of short bolts. It is intended to improve such a connection to the effect that the pretensioning force losses after tightening of the bolts are made uniform on the individual bolt connections. Essentially, this is achieved in that a specially shaped elastic ring is inserted in each case in the short bolts either between the bolt head and the machine part to be braced or in that the short bolts have a greater material strength than the long bolts.   <IMAGE>

Title: Gauge for the arrangement of stencil characters
Inventor: LUDWIG BERND
IPC: B44B3/06
Filed: 1982-11-10
Abstract: In gauges for the arrangement of stencil characters for engraving machines having a repeating stencilling machine, there is the difficulty that either only linear engravings or semi-circular or circular engravings can be made, handling, above all adjustment, being complicated and time-consuming. To provide a gauge, by means of which it is possible to make both linear engravings and the most diverse circular engravings, including the arrangement of stencil characters in the circle or in the oval or on other curves, and furthermore to make the handling of the gauge substantially easier and, whilst ensuring a diversity of possible uses, to keep the outlay in terms of construction low, it is proposed that a common baseplate (1) be equipped with a number of guides (2 to 8) which extend at a distance from and parallel to one another and in which the stencil characters (9, 30) are longitudinally displaceable and limited by stops (10, 11; 31, 32) located on both sides, that the baseplate (1) be provided with a centring (14) and with angle markings (13) extending from this, and that the guides (2 to 8) have length markings (15) on at least one side. <IMAGE>
