Patent DE-2815345-A1 (DE)
Title: Growth regulation of cotton plants - using di:methyl-piperidinium salts at low application rates
Inventor: JUNG JOHANN
IPC: A01N43/40
Filed: 1978-04-10
Abstract: Growth regulation of cotton plants is effected by applying a N,N-dimethylpiperidinium (DMP) salt at a rate of 5-24.5 g./ha. Application of DMP salts at such low rates (cf. DT 2207575) still has a significant effect (reducing negative growth and increasing yields), while plant compatibility is improved, costs are reduced and pollution hazards are reduced.

Title: Object displacement measuring system - uses contact arm fitted above machine slide and has graduated scale and photoelectric detectors
Inventor: JACOBY HANS DIETER DIPL ING DR
IPC: G01B3/00
Filed: 1978-05-12
Abstract: The measuring system comprises an elastically suspended feeler (2, 3) which can make contact with the test-piece (4). The test piece is attached to a measuring bench (6) which incorporates a graduated scale (7) and photo-electric detectors (8). These are coupled to a counter (9). Also coupled to the counter is a further detector (10) which is activated when the feeler arm comes into contact with the test-piece. This action stops the counter and arrests the relative movement of the test-piece at the same time. The counter output is fed to a display (11). Via a gate (12) activated by the detectors, the count can be stored in a memory (13) for further processing/display (11a). The second gating signal is derived from the further relative movement between test-piece and feeler.

Title: Ring laser revolution rate meter with optical switch - alternately passes in opposite directions, for if operation, and overcomes lock-in effect
Inventor: RITTER GERHARD DIPL ING
IPC: G01C19/64
Filed: 1979-02-28
Abstract: The laser gyroscope or ring laser revolution rate measurement device contains an electromagnetic radiation amplifying medium in a closed beam path traversed in opposite directions by electromagnetic beams, ie laser beams. It is designed to overcome the lockin effect which tends to synchronise the two beams to a common frequency at low revolution rates. It thus enables low revolution rate measurement. An optical switching device placed in the beam path is switched alternately for passage of a beam in one direction only. It is non-reciprocally controlled with time so that two wave packets pass round the beam path in opposite directions and alternately amplified. The beam path can be an optical wave conductor wound into a loop. In one arrangement two circulators (Z1, Z2) are connected one each at either end of a loop contg., an amplifier (V) and a frequency filler (F), connected between change-over switches (S1, S2).

Title: Constant flow mixer valve - has spring-loaded unit to compensate for change of fluid pressure
Inventor: ORSZULLOK WILLY ING GRAD
IPC: G05D7/01
Filed: 1979-07-06
Abstract: The valve automatically maintains a constant rate of flow of a fluid but may be set to different rates and is independent of fluid pressure changes. Its main application is for hot and cold water mixers. A cone-shaped valve (6) is set by operating an external hand grip (22). The gap between this valve and its seating (5) determines the rate of flow. A coil spring (15) allows movement of the valve towards its seating as the fluid pressure increases thus compensating by reducing the gap and resulting in constant rate of flow.

Title: Protective strawberry planting guide - is made up of split field cross piece arrangement and stabilises ground surface and effects material savings
Inventor: WERLE KLAUS
IPC: A01G13/00
Filed: 1979-12-28
Abstract: The strawberry planting system consists of a number of split field elements. Each field has a planting hole at a given spacing and the surface of the field slopes downward to the planting hole. Each field element has a downwards pointing cross-piece at each side. On each cross side, each field has a cross-piece and further cross-pieces run from the middle line of the planting holes to the cross-pieces. This stabilises the surface and effects material savings because of the high wall strengths of the field elements.

Title: Waterproof seal for telecommunications cable junction box - uses heating element for rapid curing of sealant in mould esp. for telecommunications
Inventor: KLINGER SIEGFRIED ING GRAD
IPC: H02G1/14
Filed: 1980-01-24
Abstract: The seal is placed inside the cable jointing box (1). A mould (2), of metal or plastic, fits over the incoming cable (5) and covers the region where the covering is stripped off and the cores (7) opened out. Inside the mould is a spiral heating element (8) the coils of which are well clear of the cable cores. When the cable is in position and the cores correctly spaced the mould is filled with a two part resin sealant. The heating element tails (9,10) are connected to a supply and the sealant rapidly cured to give a watertight end. The provision of heat assists in ensuring that curing of the sealant is complete. It also is quick, reducing the risk of moisture absorption. The mould (2) is typically located in the jointing box by cast-on ribs (3,4) attached to the latter.
