Patent DE-2218127-A1 (DE)
Title: Ice and snow dispersing agents - using ion exchange resin additives
Inventor: SCHMIDT ERHARD DIPL CHEM DR RE
IPC: C09K3/18
Filed: 1972-04-14
Abstract: Ion exchange resins in combination with neutral salts are used as ice, snow, rime and hail dispersing agents on traffic ways, esp. roads. The resin holds the salt, but being insoluble itself, cannot dissolve in the thawed H2O and drain away. Less salt is required for dispersal, with reduced corrosion hazard and environmental pollution. The dispersing salt, ctg. Na+, Cl- or also Ca++, Mg++, Fe++, Cu++, Ni++, complexions, NO3- or PO43- is mixed with the resin, pref. in the form of a powder or granulates in the spherical condition. The resins after use can be collected (e.g. at the water works) and used as fertilisers (ctg. NO3-, PO43-) or to remove toxic metal cations in other processes (e.g. ctg. K+, NH4+).

Title: Break-in detection supervisory system - has sensors with defined working frequencies hidden in interference on a common circuit
Inventor: ALLEN HOWARD JOHN BRANDSOM
IPC: G08B26/00
Filed: 1973-07-13
Abstract: The sensors indicate three states :- normal, alarm and faulty. These states may be given by modulation of a carrier or sub-carrier frequency. The sensors may be of the transponder type, and may detect movement of a door, window, or an intruder in an area, smoke, heat, pressure etc. A high amplitude noise or sweeping frequency signal may be injected into the cable to which the sensors are connected to make it difficult for an intruder to work out and simulate the frequency of response of a sensor. The system for processing uses a crystal controlled reference oscillator and a programmable digital filter. The digital filter is stepped round the required frequencies by means of a stepping pulse generator. The dedicated sensor alarm can be given for other than the normal status from a sensor.

Title: Ceramics introduced into kiln through lock - using rail-mounted locomotive with pushing bogie to drive trolleys
Inventor: BOHN PAUL
IPC: F27D99/00
Filed: 1973-10-31
Abstract: An apparatus for feeding loaded trolleys into a ceramics firing or drying kiln operates by pushing the trolleys along a rail track through a lock into the kiln; the pushing locomotive can be anchored by shoes into the rail, and then advances an auxiliary bogie to push the line of trolleys along the kiln; during this operation, the floor of the kiln is sealed by a plate attached to the moving bogie and sealed at its sides into suitable sealing troughs for the like. When the bogie has returned to its starting position, the locomotive can withdraw permitting a new trolley to be introduced, whereupon the locomotive advances and a sensor rod mounted on it regulates its approach speed to the trolley finally slowing it down as the bogie, which is now close up to the locomotive, comes into contact with the new trolley. The bogie is then advanced and the whole process repeated. The gates of the lock are operated at the appropriate intervals to permit the stacked goods to pass into the kiln. The ceramics are fed into the furance with minimum escape of hot gas, using relatively simple equipment.

Title: Plate spring made from spring steel - has additional surface of different material such as boron applied by heat treatment
Inventor: WALZ KARLHEINZ DR
IPC: F16F1/32
Filed: 1974-05-14
Abstract: The design is intended to overcome the difficulty that localised high pressure and stress can cause spring surfaces to separate and cause failure. For this reason a high friction and corrosion resistant layer is inserted between spring plates. This affects the hysteresis properties of the spring. A particular application is on the buffers of sliding armature motors. In this design boron is used for the outer surface. This increases the hardness from 430-495 VPN to over 500 VPN. In addition the surface of the steel is enriched with boron to form a boron ferrite layer.

Title: Traffic-bearing concrete or similar covering - made with prefabricated form remaining in concrete and providing joint gaps
Inventor: WEIGELE GEBHARD
IPC: E01C9/00
Filed: 1974-08-13
Abstract: The process is for the production of a ground surface covering, which can bear the weight of vehicles, made of concrete, or other suitable material. This is done by laying a prefabricated formwork pattern on the ground, which has been previously prepared as a foundation, and then filling with concrete, after which the formwork units remain in the concrete and provide the necessary joint gaps, with no further treatment required. The formwork may be made of plastic, and can add a coloured pattern to the plain gray concrete surface, and provides elastically resilient deformative qualities under the effects of frost or heavy loading.

Title: Conical cable entry nozzle of heat shrinkable material - is for sealing entry of cable into jointing box
Inventor: BACHEL ERNST
IPC: H02G3/06
Filed: 1974-08-13
Abstract: The conical nozzle is made from a heat shrinkable material which may have even shrinkage over its entire length, or alternatively the shrinkage may be a function of the diameter at any point. When the nozle is fitted over the cable and heated the length (L) is made to grip and seal onto the cable, and determined by the shrinkage (A), is then either a fixed dimension or in a fixed relationship to the cable diameter. The sealing between nozzle and cable outer sheath may be improved by incorporating a layer of heat softened adhesive on the inner surface of the cone.
