Title: Electrical proximity switch for erection in stalls
Inventor: MUELLER KARL
IPC: A61D17/00
Filed: 1981-10-29
Abstract: The invention relates to an electrical proximity switch which can be erected in stalls below a heat source. Since newborn piglets move immediately to a heat source the switch is actuated by them to generate an acoustic and/or optical signal to indicate birth. The proximity switch (10) has a pot-shaped flat housing. An electrical switch (18) is arranged in the middle of the bottom (11) thereof. The switch contains a switching knob (17) which is prestressed in an upward direction by a pressure spring. An actuation plate (14) is mounted on the switching knob. The plate (14) is supported against an inwardly extending collar (13) at the upper edge of the housing wall (12) by the switching knob (17) which is prestressed in an upward direction. When the actuation plate (14) is touched at any point the electrical switch (18) is switched, which closes an electrical circuit to, for example, an alarm bell signalling the birth of the piglets. The invention is mainly suitable for indicating the birth of piglets. <IMAGE>

Title: Improved process for the preparation of beta-chloroisobutyric acid
Inventor: ERNST HANSGEORG DIPL CHEM DR
IPC: C07C51/363
Filed: 1981-12-12
Abstract: An improved process for the preparation of beta-chloroisobutyric acid by reaction of methacrylic acid with hydrogen chloride comprises heating the methacrylic acid to temperatures of 110 to 150 DEG C in a closed reaction vessel under a hydrogen chloride gas pressure of at least 4 bar and then allowing the reaction mixture to react at the said temperatures for 1 to 3 hours under a hydrogen chloride gas pressure of at least 15 bar. beta-Chlorobutyric acid is a useful intermediate for organic syntheses. For example, (R)-(+)-beta-chloroisobutyric acid, which can be obtained therefrom by resolution of the racemate with d-ephedrine, opens up a relatively simple route for the synthesis of the side chain of optically active vitamin E, (2R, 4'R, 8'T)-alpha-tocopherol.

Patent DE-3212665-A1 (DE)
Title: Method for storing wide-band signals
Inventor: HORSTMANN WINFRIED
IPC: H04N9/86
Filed: 1982-04-05
Abstract: A method for magnetically storing wide-band signals, particularly colour video signals, is specified which is used for recording components in at least two narrow-band channels. The Y, U and V components are subdivided into signal sections for this purpose and are modulated in each case onto one subcarrier frequency. The centre frequency of the subcarrier for the brightness signal Y is approximately three times as high as the frequencies for the subcarriers of the colour difference signals U and V. By distributing the signal sections in pairs to the two recording channels and changing the time base of each signal section in the sense of an equal bandwidth requirement for all signal sections, each transmission channel is optimally utilised. The signal sections distributed to two channels are recorded in such a manner that sections of the same location are located adjacently to one another so that the effect of cross talk from one track to the adjacent track is minimised.

Patent DE-3219203-A1 (DE)
Title: Friction disc clutch/brake combination
Inventor: OTTO ALEXANDER DIPL ING
IPC: B30B15/10
Filed: 1982-05-21
Abstract: The invention proposes a friction disc clutch/brake combination, preferably for intermittently driven presses, shears or the like, with a clutch unit and a brake unit, in which, to satisfy safety requirements, the reciprocal actuation of the clutch and brake unit is effected by two systems completely identical in their action and connected in parallel. One system comprises a central pressure disc (6) which is arranged in axially displaceable fashion between the clutch and the brake unit and presses the clutch discs (2) and the brake discs (4) alternately against the associated outer pressure discs (10, 12). The second system comprises these same outer pressure discs (10, 12), which are connected firmly to one another mechanically and are likewise arranged in axially displaceable fashion, allowing the clutch discs and the brake discs to be pressed alternately against the intermediate pressure disc. In order to engage the clutch or the brake, all that is required is thus a corresponding movement of these two systems relative to one another, it being irrelevant in principle whether this movement is carried out by one system or the other or by both systems, for which reason functioning is fully maintained if one system fails. <IMAGE>

Title: Process for the continuous use of heat energy
Inventor: TEGGERS JOHANNES DIPL PHYS DR
IPC: C09K5/16
Filed: 1982-05-22
Abstract: In a process for the continuous use of heat energy, in particular for the transport of heat energy by catalytic cracking of methane and transport of the thus obtained cracked gas to the point of energy use, when the amount of heat energy at least required for operation of the cracking plant is exceeded, a partial quantity of the cracked gas is stored in a reservoir, while a quantity of methane corresponding to the stored quantity of cracked gas is fed out of a further reservoir. When the amount of heat energy at least required for operation of the cracking plant is not attained and the cracked gas reservoir is uncoupled, a second methanising plant is fed from this reservoir with a quantity of gas which is large enough for the amount of heat energy released during reaction thereof to be sufficient to operate the cracking plant. It is possible in this manner to maintain the operation of the plant, even if possibly at reduced power, when the external heat source used for heating of the cracking plant is only available with interruptions, as is the case, for example, when the cracking plant is heated with solar energy.
