Title: Dual track occupancy signalling system - measures train velocity for correspondingly delayed release of track-free signal to obtain added safety margin
Inventor: CZEHOWSKY JOSEF
IPC: B61L21/06
Filed: 1980-09-10
Abstract: The dual track occupancy system, for short single or multiple line track sections, uses a counter associated with switches at the beginning and end of the track section operated by passage of the rail vehicle. A track occupancy signal is supplied upon reaching an initial count after triggering by the train entering the track section. Two switches are used at either end of the track section, spaced to define a measuring section for determining the vehicle speed. The counter only responds to the switch signals to give a track free signal when the speed is below a given threshold, in which case the track free signal is supplied after a timed delay. The system provides an added safety margin independent of the train speed.

IPC: B60H3/06
Filed: 1981-01-31
Abstract: The invention relates to a device for heating and/or cooling, or for cooling and/or heating an air stream or the like, using Peltier elements. To achieve a heating or cooling of an air stream or the like with a comparatively high efficiency, the invention proposes that the arrangement of the Peltier elements (4-7) and the routeing of the air stream are such that the latter is passed thermally over the hot sides of the Peltier elements one after another and is fed back in countercurrent over their cool sides, or vice versa. The Peltier elements (4-7) are contained in a common housing (1, 2). The housing (1, 2) has ribs (3) or the like and is optionally fitted with rerouteing devices or the like. The invention furthermore relates to the use of such devices for cleaning air containing pollutants using sorption and catalyst materials, the air to be purified first being heated to 20-30 DEG C, then being exposed to the sorption materials and subsequently heated to 55-60 DEG C, after which it is exposed to the catalyst materials. After this the air is cooled and the purified air fed back for further use. <IMAGE>

Title: Breathing equipment
Inventor: HENKIN MELVYN L
IPC: A61M16/06
Filed: 1981-06-02
Abstract: Breathing equipment for simulation of predetermined altitudes by reduction of the oxygen content in the inhaled air comprises an inhalation line connected to a breathing mask and an exhalation line, as well as a device for mixing the exhaled air with the ambient air in order to form the inhalation air. Both lines are connected to an air storage chamber via a CO2 absorption device. The breathing mask has an opening which is dimensioned for adjustment of a predetermined proportion of oxygen in the inhalation air and communicates with the ambient air, so that part of the exhaled air is discharged to the ambient air on exhalation, whereas another part is passed through the CO2 absorption device and mixed with ambient air supplied via the opening in the breathing mask. Openings with different dimensions can be employed for simulating different altitudes. The inhalation air can be passed through a heat exchanger before being mixed with the ambient air. The breathing mask is provided with a strap arrangement with which it is fastened on the user's face. A first strap runs horizontally round the back of the head. A second strap runs from the top of the breathing mask over the head and down to the back of the head where it is connected with the first strap via two spaced-apart part-straps. The length of each strap is adjustable. <IMAGE>
Patent DE-3129905-A1 (DE)
Title: Bill post
Inventor: GOLAN HENRY
IPC: G09F15/00
Filed: 1981-07-25
Abstract: The bill posts of circular cross-section which have been conventional hitherto are disadvantageous from many points of view. Sticking bills on one above the other produces, over the course of time, a thick layer which requires considerable effort to detach. Owing to their large volumes, transportation and erection of such bill posts necessitate special vehicles and cranes. The invention provides a bill post whose side walls, which receive the bills, can be renewed easily and economically and, since the bill post according to the invention is produced by a modular-construction system, it is transported in a dismantled state and a special vehicle is thus not required. Construction and erection are carried out without special tools. As many identical levels as required can be placed one on top of the other and bill posts of different heights can thus be erected. The special cross-sectional shape permits a plurality of bill posts to be positioned one beside the other to form new decorative combinations which, furthermore, develop novel application purposes for bill posts. The bill post according to the invention has an approximately star-shaped cross-section and concave, easily exchangeable side walls.
Patent DE-3130783-A1 (DE)
Title: Plastic package
Inventor: LANGEN ALFRED
IPC: B65D75/36
Filed: 1981-08-04
Abstract: The invention provides a blister package, consisting of a bottom part and side walls which are connected thereto and by means of which a package interior is fixed, and consisting of a box-shaped lid which, in the closed state of the package, surrounds the side walls connected to the bottom part and closes off the package interior, the lid being welded to the bottom part on one side. The special feature of this package lies in the fact that a pocket-shaped inner covering (5) is provided, which consists of side walls (6) in a U-shaped arrangement and a covering (7) attached thereto, as a result of which a side opening (10) is formed, and that the lid (3) is welded in the region of the side opening (10) to the bottom part (2) along a seam (20). The package according to the invention advantageously guarantees an optimum protection for the packaged product. This is made possible on the one hand due to the fact that a pocket-shaped inner covering is provided. This inner covering, preferably produced from a transparent plastic material, protects the packaged product from above, even when the lid is open, due to the additionally provided covering. This pocket-shaped inner covering has a side opening through which the packaged product can be introduced into the package. In this case, the lid surrounding the inner covering in the closed state is advantageously welded to the pocket-shaped inner covering along the side opening. In order thus to introduce and remove a packaged product into and out of the package, the lid has to be pivoted through almost 180 DEG  in order to expose the side opening of the inner covering for inserting or removing the packaged product. An optimum protection, in particular also in respect of dust impairment, is thus provided for the article to be packaged. <IMAGE>

Title: Printing unit for a typewriter or similar office machine
Inventor: WIETRZYNSKI BOLKO DIPL ING
IPC: B41J25/24
Filed: 1982-03-27
Abstract: The frequent change-over to foreign languages with different characters or to different kinds of script necessitates an easy exchangeability of the type wheel (1) in printing units of typewriters or similar office machines. In known printing units, the type wheel (1) is slipped on to the free end of a drive shaft (19), the type wheel (1) being coupleable to the wheel receptacle (17) via a take-up pin (35). It is necessary, here, that the take-up pin (35) and an engagement orifice (7) corresponding to this be exactly in alignment. This exchange of the type wheel (1) is to be simplified by means of the invention. For this purpose, the type wheel (1) is blocked during the locating movement of the wheel receptacle (17), in such a way that the take-up pin (35) reliably engages automatically into the engagement orifice (37) of the type wheel (1) within one revolution of the wheel receptacle (17). <IMAGE>

Patent DE-3233083-A1 (DE)
Title: Eccentric press
Inventor: KOCH ELMAR DIPL ING
IPC: B30B15/00
Filed: 1982-09-06
Abstract: An eccentric press has two eccentric parts (8, 8') of invariable eccentricity, which are arranged so as to act in opposite directions on a driven eccentric shaft and are encompassed by in each case one connecting member (7, 7'). The press ram (1) is connected to the connecting members (7, 7') via two symmetrical lever arrangements (4, 4'). The lever arrangements (4, 4') consist of two parts (9, 9' and 10, 10') which are interconnected in an articulated manner and on which a stroke-adjusting device (16) acts in order to adjust the ram stroke. The joint (13, 13') arranged between the parts (9, 10, 9', 10') on the lever arrangement (4, 4') is positively guided on an adjustable movement path (B, B'). As a result, the driving forces produced by the movement of the connecting members can be transmitted to the ram (1) in a manner free from bending moments by means of the lever arrangement (4, 4') provided for force transmission. In this arrangement, no deflections occur in the ram drive, as a result of which tilting of the ram (1) in the event of loading on one side is prevented. In addition, in the eccentric press according to the invention, all of the advantages inherent in eccentric presses having a non-adjustable double eccentric, such as high operational reliability, are retained. Furthermore, the use of a double eccentric of fixed stroke makes adjustable rotary mass compensation unnecessary, since the stroke adjustment is not effected by changing the eccentricity. <IMAGE>

Patent DE-3235694-A1 (DE)
Title: Method and circuit for operating a double-pulse DC motor having no commutator
Inventor: MUELLER ROLF DR ING
IPC: H02P6/20
Filed: 1982-09-27
Abstract: The invention relates to a method and a circuit for operating a double-pulse DC motor having no commutator. It can, however, also be used for single-pulse motors of said type. Said motors are often used for operating disc memories. When such motors of the type mentioned initially are braked in operation, for example with the aid of a mechanical brake, as is often the case with direct drives for hard-disc memories, a problem can occur in the case of such motors if the motor reaches a position under the influence of the brake in which the resulting total torque cannot overcome the existing friction. The motor then does not start. The invention is based on the object of ensuring reliable starting under the said conditions. In accordance with the solution according to the invention, the starting of the motor is delayed, preferably electronically, with respect to the switch-on time and the release of the brake such that the motor can rotate after the brake has been released, under the influence of the non-electromagnetic auxiliary torque, into a position in which the electromagnetically generated torque is always positive. This is done advantageously using a suitably dimensioned RC element (1, 2) which is arranged in the commutating circuit (200, 300) or in the speed regulating circuit (100) at a point where the motor current can be influenced by relatively small control currents (Fig. 3). <IMAGE>
