Patent CH-643147-A5 (CH)
Title: Home training apparatus
Inventor: BIRUM PAUL LUDWIG EMIL
IPC: A63B23/04
Filed: 1979-04-09
Abstract: The home training apparatus is equipped with an erectable bicycle-like frame, having a saddle, pedal drive for the feet and an additional hand-crank drive instead of the handlebars for the hands, both of which act upon a common, adjustable braking apparatus. The object of the present invention is to improve physical training, especially in relation to arms and torso. Tests have shown that the desired variety of stresses on the muscles of the arms and torso can be achieved by changing the angular position of the two hand cranks. When the hand cranks set at an angle of 180 DEG  to each other - bicycle arrangement - the torso receives a certain twisting stress to left and right, while the arms can act powerfully in their circular movement. When the hand cranks are set identically with a 0 DEG  angle - rowing arrangement - the forward and backward movement and stressing of the trunk is at its maximum, which is valuable for health purposes. In the present invention, the desired variety of effect of the hand cranks is achieved, through two modes of operation, by twisting a gnarled nut (20) in such a manner that a predeterminable angular position is retained without varying continuously.
Patent CH-642502-A5 (CH)
Title: Method of electronic reproduction of a multi-colour motif
Inventor: JAEGER WALTER DIPL PHYS
IPC: H04N11/00
Filed: 1979-04-12
Abstract: So that even saturated colours can be reproduced in electronic reproduction of a multi-colour motif (1), using only two output signal sequences (SM, SP) which correspond to two colour components which overlap in colour, use is made of the fact that if one of the output signal sequences is zero, the green colour component which corresponds to the overlap must necessarily also be zero. Therefore, the second output signal sequence cannot contain green, and must therefore correspond to saturated blue or red. <IMAGE>
Patent CH-674387-A5 (CH)
Inventor: SPIESS HANSRUEDI
IPC: E02D29/14
Filed: 1987-10-12
Abstract: At their ends, the frame parts (2) of the frame have connecting lugs (4, 5) which are arranged at a different height. During assembly of the frame, two frame parts (2) lie next to one another, the connecting lugs (4, 5) of which lie one above the other at a distance apart and are connected to one another by a screw connection (13). So that the frame parts (2) are connected to one another in a positive-locking manner, the frame is turned upside down and a liquid, pasty or granulated filling material is poured into a recess on the underside of the higher connecting lug (5). The filling material also flows into the bore (6) for the screw connection (13), which bore (6) is covered by a washer (16). After the filling material has solidified, the frame can be transported either in this state or in the dismantled state and put together again in the same manner. Due to this type of assembly, mechanical working of the frame parts 2 can be dispensed with.

Patent CH-611846-A5 (CH)
Title: Apparatus for the evacuation of plastic containers
Inventor: WITTWER LOUIS
IPC: B65B31/08
Filed: 1978-07-19
Abstract: The apparatus is intended for domestic use and serves especially for sucking air out of plastic bags which are filled with foodstuffs for freezing. A hollow needle (3) is coupled via a flexible conduit (2) to a connecting nozzle (1) inserted in the suction connection of a vacuum cleaner (I). This needle (3) is used for piercing the plastic bag (II), specifically at the point where a special self-adhesive label (4) is affixed. After the air has been sucked out of the plastic bag (II), the hole used by the needle (3) is closed by means of a covering sheet of the two-part self-adhesive label (4). The bag (II) is thus prepared for the freezer compartment. To cool the motor of the vacuum cleaner, a further bore (a) is provided in the nozzle (1) next to the bore (b) for the flexible conduit (2). <IMAGE>

Abstract: This arrangement comprises a milling means enabling a plurality of cycles to be carried out in which the material is crushed slowly either by means of at least two communicating slow-compression crushers or by means of a slow-compression crusher (6) equipped with a system (9) for recycling the material from the outlet to the inlet of this crusher, whilst the pre-milled material is sent into a crusher containing balls (11), resulting in the final desired product which can subsequently be treated in a separator (13). The method and the arrangement of this invention permit, in particular, the milling of cement clinker. <IMAGE>
Patent CH-592889-A5 (CH)
Title: False twist texturiser speed indicator - simplifies design by indicating speed as function of yarn delivery rate
IPC: D02G1/02
Filed: 1975-10-03
Abstract: The indicatication of the false-twist unit speed is carried out when several of the twistrs are driven by an endless belt of which the control pulley shaft exhibits equispaced markings. The latter are sensed by photoelectric cells or electromagnetic pulse detection. The marking disc can be in the form of a gear or a perforated disc. Instead of perforations, the disc may exhibit dark and light shades for photodetection. The system ensures a high measurement accuracy, since the speed of the gear, and thus the number of counted pulses per unit of time depends on the peripheral velocity of the drive belt turning all false twist heads at the same speed. The connection of the belt driving pulley to the main drive of the texturizing frame ensures that the yarn delivery rate changes with the belt velocity, and thus with the speed of the false-twist heads.

Title: Filter for liquids - has distribution baffle with flap-valve to facilitate back washing
IPC: B01D29/00
Filed: 1971-04-21
Granted: 1972-12-08
Abstract: In multi-disc cylindrical filters commonly used for filtering the water of swimming baths, filtering efficiency is improved by placing baffles to spread the incoming liq. evenly along the filter surface, but this tends to impede the clearance of filter-blocking waste when back-flushing takes place. To overcome this disadvantage, a fairly large, non-return flap valve is fitted in the main baffle and arranged so that it remains closed during the filtering operation and is automatically opened by reverse flow liq. as soon as the back-flushing operation starts.

Abstract: 1293724 Automatic control of temperature LANDIS & GYR A G 20 April 1971 [28 April 1970 1 Feb 1971] 10238/71 Heading G3R A temperature control arrangement of a central heating installation, comprises a bridge circuit (not shown), including temperature responsive resistors and adjustable potentiometers R10, R11, Fig.1, the slidable contacts 12, 13 of which are movable by pegs 8, 9 respectively, whereby to adjust the linear operating characteristic relating the forward flow temperature of a boiler outlet to a sensed temperature (e.g. outside temperature). The pegs are linked by a graph indicator member 19 representing the said characteristic, and which is fixed to one peg and movable in the other. The indicator 19 is viewable against a coordinate scale on a front plate 16 and which has flow temperature as ordinate and outside temperature as abscissa. The slider contact 12 of R10 is carried by an insulating member 6 which also carries the  resistor R11. When peg 8 is linearly moved to adjust slider 12, the resistor R11 will be moved relative to its slider 13. Thus linear movement of peg 8 results in parallel displacement of the operating curve of a heating installation control, and movement of peg 9 results in a change in the slope thereof. A slider contact 15 connects one end 14 of R11 to a contact track (not shown) and thence to the bridge circuit. In an embodiment, Fig. 2 (not shown) both resistors are stationary, a first resistor being engaged by two slider contacts of a first adjuster and by one slider contact of a second adjuster. The second resistor is engaged by only one sliding contact.
