Title: Temp. regulator with prestressed bimetal element - has U=shaped recess in bimetal element middle shank whose arms increase bending power
Inventor: SCHUETZE MANFRED
IPC: H01H37/20
Filed: 1976-08-14
Abstract: The temp. regulator has a prestressed bimetal element whose middle shank (16) has a U-shaped recess (21). The recess legs extend from engagement point of an insulating pin (12) of the rated value adjusted (10) to the clamping point of the bimetal element (1). Thus the effective length of the middle shank for its deflection is increased. Pref. the strip formed by the U-shaped recess abuts the insulating pin and has a notch (23), ending in a recess (24) at the clamping point of the bimetal element. The design improves the regulator response at temp. changes and gives a sensitivity to very small temp. differences.

Title: Scale indicator for domestic coffee machine - has heat sensor in loose thermal coupling with hot water pipe for optional positioning
Inventor: LEUSCHNER UDO
IPC: A47J31/58
Filed: 1976-08-24
Abstract: The scale indicator is for a coffee maker having a throughflow heater provided with a heat sensor (32) which is in loose thermal coupling with the hot water pipe (26) and gives off a signal in the event of an increased rise in temperature owing to scaling up. This heat sensor has a response temperature which is reached at a specific minimum time after the hot water has turned to steam. Since this response temperature is reached at the point of installation of the heat sensor the latter can be mounted at any point on the hot water supply pipe and can thus be readily visible without great expenditure. The sensor can be coupled to the hot water pipe by a thermally insulating material (32) which allows the rise in temperature in the pipe to be passed along only slowly.

Patent DE-2649177-A1 (DE)
Inventor: KAELIN JOSEPH RICHARD
IPC: C02F3/20
Filed: 1976-10-28
Abstract: In order to avoid all of the wet sludge already situated in the wet sludge aeration vessel (13), which has been preheated as a result of the biological conversion process proceeding there, from being cooled below the pasteurization temperature by cold wet sludge freshly introduced into an aeration vessel (13), the wet sludge aeration vessel (13) is provided in its interior with two perforated bases (31, 32) subdividing it into three sequential aeration chambers (13a, 13b, 13c). Feeding means (36, 37, 38) serve to feed pure oxygen into these aeration chambers (13a, 13b, 13c). To each of the aeration chambers is assigned a wet sludge circulation apparatus (33) in order to impart angular momentum about the longitudinal axis of the aeration vessel to the wet sludge situated in the individual aeration chambers (13a, 13b, 13c). It is achieved as a result that the residence time of the otherwise rapidly rising oxygen introduced into the wet sludge is prolonged and that the settling of solids is prevented. <IMAGE>

Title: Radar confusing anti-missile system - forces low-flying missiles into conventional radar detection zone by deploying reflecting layer
Inventor: SCHOEFFL RAINER
IPC: G01S7/38
Filed: 1977-03-30
Abstract: The radar signal deflection system for anti-missile installations is based on the use of reflecting strips or "window" distributed in the air to confuse radar guidance systems fitted to low-flying missiles or aircraft. These usually fly at low altitude to evade the ground-based radar detection systems and use a radar-based navigational beam aimed at the ground over which they pass. The anti-missile measure consists in the establishment of a distributed layer or layers of reflecting material, usually in the form of metal strips or thread or metallised plastics particles. These are placed in the likely path of a low-flying missile to simulate the ground zero. The missile navigational system is thus confused and causes it to fly at a higher altitude. It can then be detected by conventional radar detection systems linked to anti-missile weaponry.
Patent DE-2715750-A1 (DE)
Inventor: HOERDER ALEXANDER DIPL ING
IPC: G06F11/36
Filed: 1977-04-07
Abstract: For a microcomputer which consists of a microprocessor (CPU), input and output chips (ET, AT), at least one system memory (SSR) and a status memory (ZR), a test circuit is provided. This circuit has the task of providing the information of the internal registers of the microprocessor for external purposes, for example for display, during a software test. This does not change the user programs provided for the microcomputer and does not impair the operation of the microcomputer itself. For this purpose, certain machine cycles in which the information of the internal registers of the microprocessor exist on the data bus (DS) of the microcomputer, are determined with the aid of a machine cycle counter (MR). To request this operation, the machine cycle counter (MR) controls a separate register read program memory (RLSR), the information of which is used instead of that of the system memory (SSR) of the microcomputer. The microcomputers equipped with the test circuit are used in protection circuits, for example in railway protection engineering. <IMAGE>

Title: Sugar cane bagasse dewatering - by low-pressure roller, deflection roller and curved deflection of serrated layer
Inventor: KAETHER WILLY
IPC: C13B15/00
Filed: 1977-04-15
Abstract: The Parent Patent described a machine for the low-pressure pre-dewatering of sugar cane bagasse in which the flat layers of bagasse were transformed into bilaterally serrated and finally curved layers. In this addn., the efforts to achieve the transformation can be relieved by arranging a deflection roller at the end of the horizontal press zone past the main roller. This is followed by a curved press zone which takes the bagasse upwards along the main roller. This is a simpler design and has less wear than the transport elements described in the Parent Patent.

Title: Ingot casting process - using spark discharge shock pulses in fluid to suppress trans:crystallisation
Inventor: KORYTOV VLADIMIR A
IPC: B22D23/10
Filed: 1977-11-14
Abstract: In the mfr. of ingots, the solidifying metal melt is treated by elastic vibrations. This consists of pulses produced by a high-tension spark discharge in a fluid which is maintained until the volume crystallisation starts. The pulse repetition frequency and energy are large enough to suppress the transcrystallisation process of the metal. The result is a fine-grained metal structure in the central zone of the ingot. The acceleration of the crystallisation process provides a higher productivity of the plant.
