Title: Wheel set guide for sets of running gear of rail vehicles which are capable of high speed
Inventor: VAN EEUWIJK WILLY DIPL-ING
IPC: B61F5/26
Filed: 1982-04-06
Abstract: In order to realise a set of running gear with supercritical running properties and in order to permit the wheel sets to set themselves radially when going around bends, the wheel set guide is provided with harder suspension in the transverse direction of the set of running gear than in the longitudinal direction of the set of running gear. Each wheel set is guided on each side by a flexurally stiff axle guide which is connected to the frame of the set of running gear by means of an axle guide joint so as to be capable of vibrating elastically about a horizontal axis (21). For the purpose of constructing the axle guide joint in an elastic fashion, the said joint is provided with annular rubber washers (16) which are arranged in vertical longitudinal planes of the set of running gear and are prestressed compressively in a horizontally transverse direction by means of an anti-fatigue bolt (17). By virtue of the shape and the material properties of the annular rubber washers (16) it is ensured that each time they are subjected to prestressing their compression spring constant which acts in the transverse direction of the set of running gear is greater than their shear spring constant which acts in its longitudinal direction. <IMAGE>

Title: Triggering of emergency alarm system on motor vehicle - using electronic switch and audio=visual warning relay activated by pressure in braking system
Inventor: LINDENMANN MAX
IPC: B60Q1/52
Filed: 1987-11-24
Abstract: The alarm signal is given intermittently by an electrical switch operated automatically by brake pressure, causing a relay to sound the horn and to flash the hazard warning lamps, pref. at the frequency of the winking indicator unit. It may be discontinued automatically when the speed of the vehicle falls to a very low value. Early warning is given to other drivers to resort to emergency braking, and to pedestrians to stop or to take evasive action. All persons directly involved are alerted, and any injuries sustained in collision are likely to be mitigated by involuntary reflex muscular tension. ADVANTAGE - Wide range of possibilities of accident avoidance is afforded with audible and/or visual warning which is given automatically during emergency braking.
Patent CH-576139-A5 (CH)
Title: Semiconductor gas sensor - heated to alternate temps. with resistance drop by gas absorption triggering fire alarm
IPC: G01M3/20
Filed: 1974-07-05
Abstract: A gas detector for use as fire alarm contains a metal-oxide semiconductor gas sensor which is repeatedly heated through an astable multivibrator with transistors to a low temp. of 30-40 degrees C at which it absorbs a gas component (CO), and to a higher temp. of 100-200 degrees C at which it releases the gas. When heated to the lower temp. a resistor is connected in a series with the sensor to indicate by its voltage rise that a reduced sensor resistance has been caused by a gas concn. above a certain threshold. This gas detector requires little electric power; it is simple yet it has a high efficiency. It can readily be set selectively for the detection of gases other than CO and is free from malfunction.

Title: Demineralization of brackish waters - by three stages of ion exchange resins
IPC: B01J49/00
Filed: 1971-02-12
Granted: 1972-10-06
Abstract: Partial or total demineralization is obtd. by using a system in which a weakly acid cationic exchanger in its Na form which removes such as Mg and Ca, followed by a strongly acid cationic exchanger in its H form which removes Na, and then by a weakly basic anionic exchanger in its OH form which removes such as Cl- and SO4. H2SO4 is used for regenerating the cationic exchangers, and Na2CO3 for the anionic exchanger. The use of the weakly acid exchanger increases the capacity of the system.

Title: Shaping machine for dough in bread-making - with successive rollings on conveyor to desired height
IPC: A21C7/01
Filed: 1973-03-08
Granted: 1974-10-04
Abstract: The dough, in pieces of a definite, wt. or vol., are passed between a pair of rollers and are transformed into flat cakes with a thickness corresp. to the desired length of the finished loaf. This thickness also depends upon the water content of the dough and its state of fermentation. The cake falls on an endless belt and is carried forward until its leading edge meets a loaded felt sheet; the cake, thus driven forward on its lower face and held back on its upper surface, undergoes a second rolling process. The rolled cake is then conducted to a pre-elongation passage and in its new form is carried to the elongation platform below the lower strand of the conveyor belt. It now undergoes a second elongation phase, in which it progressively attains the section and length required. At the end of the belt it falls, by gravity, on to another conveyor or a reception table. Lumps of dough, each for making one loaf, are produced in successive stages, which are regular, homogeneous and of good appearance in the pre-baking stage.

Patent CH-696141-A5 (CH)
Inventor: SIEGRIST RONALD
IPC: B29C45/58
Filed: 2005-10-11
Abstract: The method involves transforming torque and movement of an electric motor by a nonlinear transformation device. The torque and the movement of the electric motor are transferred to an injecting axle to be driven, and the torque of the electric motor above a nominal rotation speed is minimized. The electric motor is operated occasionally with number of revolutions above the nominal rotation speed. A nonlinear transmission behavior of the transformation device is partially compensated with respect to a speed of the injecting axle by number of revolution change of the electric motor. An independent claim is also included for a device for executing a method of driving an injecting axle by a fuel processing machine.
