Title: Pollution reducing system for IC engine - with ozone generator in air intake filter to ensure complete combustion
IPC: F01N3/037
Filed: 1975-01-15
Abstract: The internal combustion engine (2) has an air intake filter (11) which contains an ozone generator. The ozone generator consists of a stainless steel electrode connected to earth and a high tension electrode of a suitable dielectric connected to the high tension coil (14) of the transformer (12). Ozone is generated as the air flowing through the filter (11) passes between the electrodes. The ozone reduces the amount of carbon monoxide and nitrous oxide in the exhaust gases. In addition the silencer (7) has swirl vanes which direct any unburnt hydrocarbons into the pipe (9) so that they are recirculated to the inlet manifold (4).
Patent CH-669454-A5 (CH)
Inventor: REHMANN ROBERT
IPC: F42C11/04
Filed: 1984-02-24
Abstract: In the method of increasing the detonation energy in an electromagnetic fuze system of a low-acceleration projectile a detonator generator which is held in an inactive or rest position by an elastic force, is accelerated along a predetermined travel path in the rear portion of a housing at the onset of the firing acceleration. The detonator generator is accelerated such that the detonator generator impacts upon an impact body which is provided with a central bore. As a result, a reaction member of the detonator generator inactivates its mechanical safety device and is accelerated, thus providing the detonation energy. In the retarding phase the detonator generator is returned into its original position by means of the elastic force and thus is ready for detonation. In comparison to known methods and apparatus there can thus be dispensed with an external power supply, whereby safety is increased with respect to maintenance, tests and firing.
Patent CH-630131-A5 (CH)
Title: Concrete surfacing with joints between surfacing sections of a road
Inventor: VOGT KURT
IPC: E01C11/10
Filed: 1980-02-05
Abstract: In the concrete surfacing with joints between the abutting surfacing sections (10, 20), the joints (11) are arranged in a zig-zag manner and, on both sides of the joint (11), a cutout in the concrete is filled with synthetic resin mortar or with cement mortar modified with synthetic resin (23, 24). The interface between concrete and synthetic resin mortar is likewise designed in a zig-zag manner. The result is that no abrupt load variations can arise at the surfacing edges at the joints, in particular when vehicles are equipped with tracks. Existing road surfacings can be renovated easily, the concrete surfacing sections being marked out in a toothed manner on both sides of the joint and the joint being maintained in the previous straight shape. As synthetic resin mortar has a greater resistance to impact than concrete, there is also no danger in this case that the straight joint could split out. <IMAGE>

Patent CH-628766-A5 (CH)
Title: Electronic device for brightness control of a sodium-vapour high-pressure lamp
Inventor: COUFAL HANSPETER
IPC: H05B41/392
Filed: 1978-04-06
Abstract: The electrical energy supplied to the sodium-vapour high-pressure lamp (20) is controlled as a function of a DC control voltage (US). This control is achieved by means of a circuit arrangement (IC1, R3-R11, C4-C6, D1) with whose aid the time or angle of triggering of a triac (TR1) is variable within each AC voltage half-cycle. In order to prevent the lamp (20) being completely extinguished inadvertently when it is set to the minimum brightness, a second circuit arrangement (30, 42, R12-R18, C7, D3, T1, 52, R25-R27, C9, D3, D5) is provided by means of which the required minimum current intensity of the current flowing through the lamp (20) is ensured irrespective of the magnitude of the DC control voltage (US). The voltage applied to the lamp (20) and the required minimum current intensity of the lamp reduce in accordance with the special characteristic of a sodium-vapour high-pressure lamp when the temperature of the lamp falls following the reduction in the lamp brightness. The voltage across the lamp (20) reduces to the same extent when the voltage across the triac (TR1) increases, so that the minimum current intensity is controlled automatically and indirectly as a function of the lamp temperature. The device created is used, for example, for brightness control of sodium-vapour high-pressure lamps in roadway and tunnel illumination systems. <IMAGE>

Title: High-efficient heat transfer system
Inventor: D ONOFRIO ANTONIO
IPC: F25B39/00
Filed: 1983-08-09
Abstract: The system comprises at least one evaporator (E) and at least two condensers (C). These each consist of bundles of coils of elongate form, enclosed in tubes (2, 10). In the tube bundle of the evaporator (E), at least one fluid circulates, while water which receives heat from at least two different fluids circulates in the condensers (C). A compressor (K) receives the said fluids coming from the evaporator (E) before transferring them, after compression has taken place, into the two condensers (C). The fluids consist of dichlorodifluoromethane (Freon 12) and chlorodifluoromethane (Freon 22) and circulate in a direction opposite to that of the water. In the evaporator, the fluids flow mixed with one another, while they flow separately in the condensers (10', 10''), i.e. the first (Freon 22) flows in the upper condenser (10') and the second (Freon 12) flows in the lower condenser (10''). With the system, a useful temperature of up to 75 DEG C is obtained, with the advantage of doing away with a boiler of the conventional type in a heating installation. <IMAGE>

Title: Method for making a load-supporting and/or stable pillar in the ground and a construction containing a number of such ground pillars
Inventor: UFFEN BEREND PIETER RENE
IPC: E02D5/46
Filed: 1999-05-20
Granted: 2000-05-02
Abstract: A method for making a load-supporting and/or stable pillar in the ground. This ground pillar consists of a hardened mixture of a binding material such as cement, possibly in combination with another binding material, and materials present in the ground. So as not to have to insert unnecessarily large quantities of binding material to achieve sufficient stabilization in some ground types, particularly those comprising organic clay and/or peat, a column of sand is inserted prior to the injection of the binding agent; the sand column is mixed with a proportion of the original earth and the binding agent is injected into this earth mixture in a subsequent step. The sand column should preferably have a smaller actual diameter that the load-bearing and/or stable ground pillar finally produced.

Patent CH-609374-A5 (CH)
Title: Detergent
Inventor: GRAND PAUL SHELDON
IPC: G03G15/05
Filed: 1972-08-30
Abstract: The detergent contains the following components:   a) an anionic surfactant which is an alkyl polyoxyethyl sulphate and/or a methoxyalkyl sulphate in which one oxygen of the sulphate group and the oxygen of the methoxy group are directly linked to vicinal carbon atoms on the alkyl group,   b) sodium silicate,   c) a non-ionic surfactant and   d) a water-soluble polymer which counters soil redeposition. In terms of its cleansing power, it is comparable or even superior to a phosphate-containing heavy-duty detergent. It can be formulated in such a way that it contains negligible amounts of sodium carbonate or is free of alkali metal carbonates. If an alkali metal carbonate is employed, the content of non-ionic surfactant of component c) in the detergent can be reduced by comparison with a corresponding formulation without alkali metal carbonate. The detergent is preferably phosphate-free. While having the same detergent action it is considerably more environmentally friendly than any phosphate-containing heavy-duty detergent hitherto customary.

Patent CH-622096-A5 (CH)
Title: Balance with digital indication
Inventor: METTLER H C ERHARD DR
IPC: G01G3/02
Filed: 1977-11-14
Abstract: The balance having electromagnetic force compensation possesses two weighing ranges, a switch (28'') making it possible to switch to the zero point of the finer weighing range at any point within the coarser weighing range, whereupon the entire fine range having the higher indicating resolution is in each case available once again. The non-linearities of the balance characteristic are substantially greater in the upper load range than in the lower load range. Moreover it is desirable to have not only a fine range with a variable zero point, but also a middle range with a constant zero point. In the light of these two aspects, there is additionally present a switch (64), by means of which a change-over can be made to a third weighing range which is greater than the above-mentioned finer range, but which has a higher indicating resolution than the coarser range. <IMAGE>
Patent CH-618379-A5 (CH)
Title: Injection-moulding machine
IPC: B29C49/06
Filed: 1977-12-02
Abstract: Injection is followed by blowing of the container, the neck of which is smaller than the body. The machine includes injection moulds (22) and blowing moulds (24) comprising cavities extending along the axes of the moulds. It furthermore includes forming cores (26) which can be aligned either with the blowing moulds (24) or with the injection moulds (22). Such a forming core (26), once aligned, can also penetrate or be removed from the cavities. Ring segments (clips) (80, 82) are also positioned around the forming cores (26). These segments (clips) (80, 82) can be moved so as to be in the closed position, in which they interact with the forming core, or in an open position, in which a blown container (C) can be released from the segments (clips) (80, 82) and from the forming core (26). The cross-sections of the various cavities perpendicular to the axis (18) of the mould, at each point between the inlet and the bottom of each cavity, are as large as the other cross-sections located between them and the bottom of the cavity. As regards the segments (clips) (80, 82), they form a part corresponding to the neck of a container, narrower than the inlet of the blowing mould. These segments (clips) (80, 82) closed up on a blown container can remove it when the forming core (26) itself is withdrawn from its cavity. In such a machine, the blowing mould (24), together with the injection mould (22), are not formed from elements which separate on demoulding. <IMAGE>
