Abstract: A drainage device comprises an inner core 4 formed with a number of projections 5 and corresponding recesses 6 having flat apexes or tops and disposed in staggered rows, to define non-linear drainage channels between the core and two non-woven fitter sheets 8, 9 which are mounted adjacent the two surfaces of core 4. A drain pipe 2 is inserted between two extending edge portions 12, 13 of the filter sheets 8 and 9. The drainage device, when disposed underground, can thus collect underground water, which is suitably filtered by sheets 8, 9 and flows through the channels adjacent core 4 so as to be discharged through pipe 2. <IMAGE>

Abstract: Body noise or mechanical vibrations are damped by a sound or noise damping covering that may be secured permanently or temperarily to the surfaces of a body to be damped in the manner of an adhesive tape. The tape or band type damping covering comprises two layers of platelet elements of highly elastic material interconnected with play, for example by hooks. The layers are so arranged that the platelet elements in one layer are staggered relative to the platelet elements in the other layer. An intermediate layer of a plastic type material is interposed between the two outer platelet layers. The plastic material converts shearing stresses and hence the vibrations into heat. The plastic material may be a gel which absorbs liquid.

Title: Combined valve
Inventor: BERTKE HEINRICH ING GRAD
IPC: F16K31/06
Filed: 1981-08-18
Abstract: In an alternatively blocking or pressure-controlling combined valve, a valve-closing element (26) is influenced on opposite sides; on the one side by a magnetic coil (30) having magnetic armature (34) as well as a closing spring (28), and, on the other side, by a pressure-controller measuring unit (36) having a loading spring (42). The pressure-controller measuring unit (36) has a membrane chamber (40), which is in connection with an outlet-side chamber (20) of a valve housing (10) and is closed off by a control membrane (38). The membrane chamber (40) is in connection via a strongly throttled connection (52, 54, 56) with an inlet-side chamber (18). The armature (34) governs a less strongly throttled connection (46) between the chamber (20) and the diaphragm chamber (40). This connection is blocked when the magnetic coil (32) is in the non-excited state and released when the magnetic coil (32) is in the excited state. Thereby, the valve-closing element (26) in the closing position is relieved of the force of the loading spring (42) of the pressure-controller measuring unit. <IMAGE>

Abstract: method and apparatus are described for reducing the "dead-time" of a Geiger-Muller tube to about 5 or 6 microseconds in which the initial fall in anode voltage of the tube caused by a gamma-ray photon penetrating its wall and ionising the gas in the tube is amplified and the amplified signal used to switch the anode voltage to a lower value, thereby inhibiting further ionisation of the gas in the Geiger-Müllertube. After a short period of time in the range 3 to 10 microseconds, preferably 5 to 6 microseconds, the anode voltage is switched back to the original relatively higher voltage.

IPC: B60N2/90

Abstract: An improved track fitting (10) for anchoring a seat to a seat track (12) has an "anti-rattle" fastener member (40) for forcing a flanged top portion of a movement-restricting shear pin (28) against the top of the seat track (12) to prevent rattle and wear due to vibrations. A pivoted lever (30, 34) which also functions as a cover plate for the track fitting is mounted on the body of the track fitting for lifting the shear pin (28) against the force of a spring (38) which normally urges the shear pin (28) into locking engagement with one of the slots in a seat track. To prevent tampering by a passenger, the lever (30, 34) is rendered inoperable when the anti-rattle fastener member (40) has been actuated. A leaf spring (50) carried by the lever (30, 34) engages a body portion (20) of the track fitting and prevents the lever (30, 34) from rattling due to vibration. The lever (30, 34) can lock the shear pin (28) in its upper, disengaged, position as the track fitting (10) is lowered into the seat track (12) and can then be released so that the shear pin (28) will drop into one of the slots in the seat track (12) automatically as the fitting is moved slightly fore or aft.

Abstract: With the aid of anisotropic etching techniques, such as plasma etching and reactive ion etching, inter-connection patterns can be obtained having accurately defined rims. According to the invention, these rims are provided interalia at the area of contacts to be formed. The contacting zone thus formed, which has an accurately defined form, can be manufactured with rims of, for example, a refractory metal or polycrystalline silicon. In the latter case, a semiconductor zone (emitter zone, base contact zone, source, drain etc.) can be formed through the polycrystalline silicon in the subjacent semiconductor body. In this manner, very small structures can be obtained, whilst moreover different kinds of transistors can be manufactured in the same semiconductor body.

IPC: F16H61/00

Abstract: A control system for an automatic transmission which includes one or more hydraulically actuated friction engaging mechanisms (7, 9, 10). An electrical control device (30) receives electrical signals representing engine load and vehicle speed from sensors (31,32) for these quantities, decides which speed stage of the transmission should currently be engaged, and selectively supplies actuating electrical energy to one or more hydraulic fluid pressure switching valves (23,24,25). These valves selectively provide supply of line pressure from a line pressure generator (18) to the hydraulically actuated friction engaging mechanisms so as selectively to engage the desired speed stage of the transmission. This line pressure generator which produces the line pressure is controlled according to the current value of a certain parameter representative of engine load. The value of the line pressure generated by this line pressure generator varies in response to the current value of this parameter representative of engine load. Accordingly the value of line pressure can be adjusted according to engine load so as to be most appropriate for engaging each one of the friction engaging mechanisms from its disengaged condition when so required, the line pressure being thus varied in response to engine load which determines the torque which the friction engaging mechanisms will each be required to transmit when engaged. Thus both jerky engagement and also slippage during the process of engagement of the friction engaging mechanisms can be prevented, and such smooth engagement of the friction engaging mechanisms ensures long life for the transmission.

Abstract: In an arrangement for modifying the salt concentration of liquids, it is desired the economy, the application range and the effect on environmental conditions to increase. For this reason, it is intended to produce an energy-saving, environmentally friendly and technically easily controllable arrangement for modifying the salt concentration of liquids in wide concentration ranges with very simple means without ion exchange and without electrolytic deposition. According to the invention, the simultaneous effect of a magnetic and an electric alternating field on the liquid causes ion migration while preventing ion recombination. Selective ion migration leads to local zones of different ion concentration and polarity from which the volumes of liquid can be removed. The change in polarity of the alternating fields prevents electrolytic deposition, in particular of depositable metals, on the electrodes.
