Title: Cleaner for contaminated water esp. in fish pond - has compartmented filter tank pumped through with oxygenated water
Inventor: ROWE KEITH STANLEY
IPC: C02F3/04
Filed: 1980-07-30
Abstract: A tank is divided by perforated partitions into upper and lower chambers, and the lower partition supports the filtration medium for the treatment of contaminated water into which oxygen has been injected. An inlet pipe and an outlet pipe are fitted in the topmost zone, and the inlet pipe is above the outlet pipe. The inlet pipe sprays water through a number of holes along its wall. There are means of feeding back the water from the zone of the bottom partition into the outlet pipe, so that the water passes from above, through the filtration medium and into the leads back to the outlet pipe. For pref. the leads for the filtered water comprise at least one pipe starting in the partition zone and ending in the outlet pipe. The feedback leads comprise for pref. a number of riser pipes ending at the outlet pipe, which joint a pipe laid horizontally on the partition and having a large number of holes. The bottom compartment has a drain which is closed during working. Provides a means by which algae and organic impurities can be removed efficiently and reliably from fish ponds and aquaria.

Patent DE-3044692-A1 (DE)
Title: Determining fuse current versus time characteristic - by adjusting diffusion of low melting point material into element material, typically tin and silver
Inventor: BEHSE GABRIELE DIPL ING
IPC: H01H69/02
Filed: 1980-11-27
Abstract: The diffusion process is particularly applicable to determining current-time characteristics for semiconductor fuses. The method relates to fuses in which the melting point is determined by the addition of a reactive material at one point on the basic fuse element material, for example by adding tin to a silver strip. The additive material has a lower melting point than the base, but, when molten, reacts with the base to affect its melting point. In the process the additive material, typically tin, is diffused into the element material, silver, by a heat treatment process. The temperature and time relationship of this process are adjusted to give the required fusing characteristic. With the process the fuse can be designed for a specific duty, for example for a semiconductor a definite knee point between short circuit and long time fusing can be introduced.

Title: High temperature cylinder valve - has hollow cylinder with cross passage in refractory lined steel body
Inventor: WORLEY ARTHUR C
IPC: F16K5/04
Filed: 1980-12-05
Abstract: The cylinder valve comprises a hollow cylinder with a cross-passage, for use as a valve in high temperature fluid solid service, to block flow. The cylinder is enclosed in a refractory lined steel body which includes a main flow passage. The valve cylinder can be rotated 90 degrees about its longitudinal axis to either fully open or fully close the flow passage in the extreme cases. It can also function in an intermediate position as a throttle. Water or other coolant flow may be maintained through the cylinder if hollow, or the cylinder can be solid for small size valves. The refractory in the main flow passage surrounding the cylinder serves the dual purpose of valve seat and as insulation against extreme temperatures.

Title: Mounting for a shaft held in a housing
Inventor: SCHARD LOTHAR ING GRAD
IPC: F16C25/06
Filed: 1981-01-20
Abstract: A shaft (4) held in two ball bearings (1, 2) in a housing (3) and subject to high running requirements is to be free from axial play without the imposition of unnecessarily high friction torques while remaining simple to assemble. One bearing (1) is designed as a fixed bearing, while the outer race (5) of the other bearing (2) is initially held in the seat (6) of the housing (3) in a manner which allows slight axial displacement and is subject to the force of the spring (8) which gives the mounting the desired axial preload. The last assembly operation is the fixing of the outer race (5) in its seat (6), which is accomplished by bonding or welding or shrinking. <IMAGE>

Title: Pushrod for the actuation of an inlet or exhaust valve of an internal combustion engine
Inventor: USUI MASAYOSHI
IPC: F01L1/14
Filed: 1981-02-17
Abstract: A valve actuation pushrod for an internal combustion engine has a metal tube (1), which has end members (2, 2') with hardened, curved outer surfaces and which are welded to corresponding ends of the tube. A tubular metal member (3) has a length somewhat shorter than that of the tube (1) and by means of pressure is pressed into the tube or onto the wall of the tube. At least one of the ends of the tubular member (3) is distanced from the welded part between the tube (1) and the corresponding end member (2, 2'). In this way the problem of vibration between the valve head and the valve seat of the inlet or exhaust valve of the engine can be minimised owing to the differing vibrations of the tube and of the tubular member, since at least one end of the tubular member is not in contact with the corresponding welded part. <IMAGE>

Title: Chain of lights for a Christmas tree
Inventor: GUZYNDOWSKI HEINZ
IPC: F21S4/10
Filed: 1981-03-12
Abstract: A chain of lights for a Christmas tree, the cap of the candles (bulbs) being provided on both sides with in each case one plug contact for accommodating in each case one plug with the cable located thereon. A cable is connected to the mains plug which is provided while a second cable can be plugged in loosely with the plug in order to close the circuit. All the candles are connected to one another via loose plugs and cables and can be separated from one another. In the case of known chains of lights, worry often arose if the electric candles could not be plugged in correctly, because the individual branches of the tree were too far apart from one another and the individual cables between the candles were too short. Packing the chain of lights back into the box after use also resulted in difficulties. These and other disadvantages of the conventional chain of lights are now overcome by the measures which have been taken.

Title: Thyristor triggering device with auxiliary trigger thyristor
Inventor: CORDES AXEL
IPC: H03K17/73
Filed: 1981-04-03
Abstract: To trigger a thyristor (3), a capacitor (1), which can be charged up by positive anode voltage of the thyristor, is discharged to the gate electrode (8) of the thyristor by triggering the auxiliary thyristor (7). For this purpose, the capacitor can be connected with one connection to the cathode and with the other connection via a resistor (4) to a junction (5) between a diode (9) and the auxiliary thyristor from the thyristor anode (6) to the gate electrode (8). The duration of the gating current is determined by the capacitance of the capacitor and the resistance and can be selected to be long enough for reliable triggering by means of light-pulse-triggerable auxiliary thyristors to be possible even under more difficult conditions such as, for example, parallel operation of a number of thyristors, highly inductive load or load current oscillations. <IMAGE>

Title: Method for varying the power output of a spring brake cylinder having a pre-loaded spring in relation to at least one further identical spring brake cylinder of a motor vehicle emergency brake, and device for implementing the method
Inventor: UNSER KARL-HEINZ
IPC: B60T13/38
Filed: 1982-02-04
Abstract: The invention relates to a method for varying the power output of a spring brake cylinder in relation to a further identical spring brake cylinder of a motor vehicle emergency brake, and to a device for implementing this method. Differing residual stored pressures are generated in the spring brake cylinder according to a required differing power output. When the brake is operated, the spring brake cylinder with the lower stored pressure is first discharged and the discharging of the spring brake cylinder with the higher stored pressure is initiated as soon as a pressure loss corresponding to the initial pressure difference is reached in the other spring brake cylinder. The higher stored pressure results, in the one spring brake cylinder, in a preloading force which keeps the power output, over its graduated range, lower by a constant amount than that of the other spring brake cylinder. When fully vented, on the other hand, the full spring forces of both cylinders are effective for braking. The device has a relay valve in order to feed, for example, compressed air at varying pressure to the spring brake cylinders. The latter are discharged with a time delay, this being initiated at the spring brake cylinder with the smaller stored pressure.
