Title: Alarm signalling device, particularly for monitoring high-voltage towers
Inventor: WELTE ELMAR
IPC: G08B25/10
Filed: 1987-05-26
Abstract: An alarm signalling device (10), particularly for monitoring high-voltage lattice towers (11) at risk from sabotage, is to be designed for maintenance-free continuous operation and low rate of false alarms. For this purpose, at least one timed-alarm sensor (16.1) responding to significant changes in the thermal radiation situation in the environment of a tower footing (13) is provided which, at the same time, is designed as infrared sensor for detecting any welding flame. A silent alarm is triggered when the alarm situation has existed for at least a typical time interval and, in addition, a pressure sensor (16.3) records an explosion pressure wave or at least one sensor (16.2) for structure-borne sound, which is attached to lattice tower struts (44), detects continuing manipulations (sawing or screwing) on the tower (11). The signal transmitter (15) transmits, apart from the pure alarm information (45), an identification of the tower (11) affected and in addition, if necessary, the current sensor signals (34), including those from an airborne-sound microphone for picking up the current noises in the environment of the tower (11), to an operations control centre for immediate assessment of the sabotage case. The autonomous local power supply unit (19) is subdivided into a long-time battery (20) for permanent low-power operational readiness of the passive sensors (16) and of the timed-alarm device (31), on the one hand, and, on the other hand, into a power battery system (21), which ...

Patent DE-3733578-A1 (DE)
Title: Modified spike system
Inventor: REINKE REINHARD DIPL ING
IPC: B60C11/16
Filed: 1987-10-03
Abstract: Technical objective of the invention The damage to roads caused by tyres with spikes was classified in 1974 as considerable by the conference of the minister of transport, in particular because on average car drivers waited too long before changing tyres and as a result the spikes damaged the surface of the road when it was free of ice and snow. As a consequence of this realisation, tyres with spikes were no longer permitted. Until now, no alternative means of ensuring road holding and reducing the braking distance on ice and compacted snow has been disclosed. (Apart from several plastic snow chain structures with steel pins which are laborious to install and remove and stress the damping system to a considerable degree). The modified spike system can be adapted to the prevailing weather (ice, thaw) within seconds at any filling station. Furthermore, a setting which does not damage the road can be achieved by virtue of the ability to control the pressure on the ice needles. Solution of the problem Each ice needle is not only borne by a piston-cylinder system but also pressure-controlled. (Drawing 1, No. 1, No. 2, No. 3, No. 11) By connecting in series all the individual spike systems necessary for a tyre surface, the entire tyre tread can be supplied with ice needles (Drawing 1, No. 10 and No. 5 and 6) Area of application Winter tyres and spiked tyres for passenger cars and lorries. <IMAGE>

Title: Fin-stabilised sub-calibre discarding-sabot projectile
Inventor: BECKER WILHELM ING GRAD
IPC: F42B14/06
Filed: 1987-12-12
Abstract: The invention relates to a sub-calibre projectile arrangement having discarding-sabot segments which can be ejected. Normally, detrimental effects (discarding-sabot impact) occur on the projectile body during the process of releasing the discarding-sabot segments, which effects lead to departure errors and hit inaccuracies. This disadvantage is considerably reduced by means of the device according to the invention in that at least one micro-notch (28) having a width of a few  mu m is introduced as a weak point into each discarding-sabot segment (18) from the side of the positively locking zone (30) so that, although axial compression stresses are transmitted during firing, the discarding-sabot segment can be decomposed into at least two parts, however, on leaving the barrel nozzle as a result of the tensile stresses which occur in the positively locking zone region during the release process. In consequence, disturbing influences on the projectile body are considerably reduced and the hit accuracy is improved. <IMAGE>

Title: Single-axle handcart for transporting loads in a manner which requires virtually no carrying force
Inventor: BOLDT WILFRIED
IPC: B62B1/10
Filed: 1987-12-29
Abstract: When transporting loads by means of conventional, single-axle handcarts, it is necessary, in addition to the pushing or pulling force, to apply a carrying force since the centre of gravity of the load lies between the wheel axle and the handle. In order to minimise this carrying force it is necessary to shift the centre of gravity of the load as far as possible onto the wheel axle in the travelling position of the handcart and to hold it there even when there is movement of the handle caused by walking. According to the invention, this is achieved by virtue of the fact that on the wheel frame, above the wheel axle, there are mounted as a support circular arc-shaped guides (rails, runners etc.) on which the load rests movably and when the handle height has been adjusted individually in the position of travel settles - following the gravitational force - over the wheel axle since then the lowest point of the guides and the centre of gravity of the load lie on a perpendicular line with the wheel axle and swing slightly about this line in the event of movements during transportation.

Title: Device for damping temperature fluctuations in thermostats
Inventor: HUBER PETER
IPC: B01L7/00
Filed: 1988-07-06
Abstract: The invention relates to a device for damping temperature fluctuations in liquids in the case of suspended, bath, circulation, through-flow and the like thermostats. The device according to the invention is characterised in that a liquid stream generated by a pump is guided in a flow guide (8) which has, at least in part, an extension (9) made of thermally conductive material which increases the cross-section and/or surface and/or extends the flow guide (8). An extension (9) made of thermally conductive material, which increases the cross-section and/or surface and/or extends the flow guide (8) offers to the liquid stream a sufficient contact surface in order to be able to smooth out, in particular, short-term temperature fluctuations by means of giving off (dissipating) or absorbing heat on the part of the flow guide. In this case, the flow guide (8) can be designed in the region of its extension (9) as an additional extension of the flow guide (8) which winds around the insert container (1) in the shape of a helix, in which extension temperature-controlling liquid can be introduced via a connection (13), and can be fed back via outlet openings (19) and overflow openings (17) into the temperature-controlling bath of the thermostat (Figure 2). <IMAGE>

Abstract: The invention relates to a ski brake with two brake arms arranged on both sides of the ski, which are respectively formed with an adjoining pivot-shaft part and a holding arm made of an essentially Z-shaped round wire piece. In this connection, the pivot-shaft parts are aligned approximately at right angles to the longitudinal axis of the ski and approximately coaxially with one another and mounted on the upper side of the ski by means of a holding plate. Furthermore, the free ends of the holding arms are angled towards one another and serve as a bearing for a pedal which can be operated by the ski boot and which forms an arm of a toggle lever, the second arm of which is mounted firmly on the ski at a distance from the pivot-shaft parts and the toggle joint of which is formed by a pivot and slide bearing, the brake arms being pivotable, against elastic force, out of the braking position into a position parallel to the ski and, in relation to the ends of the holding arms, pivotable in towards the longitudinal axis of the ski into a position of readiness, and the pivoting-in taking place by means of a relative movement of the pedal in relation to the holding arms. To achieve the aim of developing and designing such a ski brake in such a manner that, while maintaining its specific advantages, a simplification of the pedal can be achieved, which on the one hand permits more economical manufacture and on the other hand increases the operational safety of the ski brake, the pedal (9, 29) has at least one operating element (15, 34) which is provided to interact with the angled sections (8, 28) of the holding arms (6, 26).
