Title: Simple versatile switch with manual operating member - has moving iron core of electromagnet forming part of current-operated automatic release mechanism
Inventor: BAER SIEGFRIED
IPC: H01H51/08
Filed: 1979-06-09
Abstract: The switch has a switching mechanism with contacts and is operated by an electromagnet with a moving iron core. A manual operating member is located before the electromagnet. The path of travel of the iron core cuts the path travelled by the manual operating member. The switch can thus be operated by hand independently of the current through the electromagnet. No modification to the switch is required. The iron core acts simply as intermediary. The impulse force from the manual member is transferred to the iron core, which moves and causes the switching of the contacts in the same way as it would if it has been moved by a current through the coil of the electromagnet. No special devices or mechanism is needed to link the manual member to the switching mechanism.

Title: Air conditioning equipment for kitchen - has heat storage ice and heat exchange system to use heat produced during cooking
Inventor: KALBOW HEINZ DIPL ING
IPC: F25D17/02
Filed: 1980-03-21
Abstract: The air conditioning device is for rooms with short term heat yield. The heat to be conducted is taken up in an ice storage. The latter delivers heat outside the heat yield times by means of a cooling circuit. During the heat yield time it absorbs heat from the room through a separate heat exchange system. The latter transports a cooling conveying medium in a closed circuit through a heat exchanger set into operation by the room air and the ice storage. The conveying medium is inert w.r.t. ice. It flows round the ice in direct contact. A pump can be used to drive the cooling medium. The speed of flow can be regulated. Pref. the medium is a liq. having a specific gravity significantly different from that of the salt water forming the storage ice. The system operates under electrical control with a simple main switch (43) with a display lamp (44) for indicating operation, two illuminating lamps (46) for the cooking plate and indicator lamp (47) for the ventilator fan motor (6).

Abstract: The operating voltage of the light sources, in working environments whose luminance is to be controlled, is changed in the sense of luminance variations in dependence on time. The changes are carried out within selectable limit values. The lower limit value corresponds to a voltage value corresponding to a still sufficient brightness. The time dependent voltage function has pref. constant positive or negative rising values. This time dependent voltage function may correspond to a steady, constant curve. The process is carried out by a device with suitable electric and electronic modules for generating pre-programmed vary1ng operating voltage values.

Title: Bar chart graphic display appts. - uses analogue measurement values with bar directional changes for parameters exceeding defined thresholds
Inventor: BEHNERT REINHARD DIPL ING
IPC: G01R13/00
Filed: 1980-09-05
Abstract: The graphic display shows analogue measurement parameter values in the form of a bar chart whose bar lengths corresp. to parameter amplitudes. It provides a reliable indication of measurement values using a single colour display. The display bars (10,11) are subjected to directional changes when their corresp. measurement parameters exceed defined threshold values. The variations in direction of the bars are dependent on variable parameters. Each bar may have an associated display field (13,14) in which the value of the parameter which it represents is displayed numerically. The alarm value of display for excessive values is increased if a bar changes when a permissible limit is exceeded so as to draw attention to the parameter concerned.

Title: Electronic measuring device for determining the average dimension of moving workpieces in conjunction with arbitrarily large interruptions of the measuring surface
Inventor: FRITZSCHE GEROLD DIPL ING
IPC: G01B7/00
Filed: 1981-01-15
Abstract: The invention relates to an electronic measuring device consisting of measuring heads, a measuring amplifier, an averaging integrator, a display and control circuits, which is predominantly used in the size control of centreless grinding machines having the measuring point arranged on the tool track. Reliable measured values are obtained by averaging independently of arbitrary interruptions of the measuring surface. The object of the invention is to make use of measuring heads having a damped measuring lever and of a lifting device so as to link different functional units in such a way that an averaging integrator of known design outputs a measured value whenever there is no interruption of the measuring surface over the measuring time. According to the invention, the electronic measuring device contains two comparators which compare the damped falling measuring signal with an upper threshold value and with a variable comparison value, which initiate averaging when the measuring lever is placed against the workpiece, and which in the event of an interruption of the measuring surface control a scanning motion of the measuring lever by reduction of the comparison value in stages until the measuring lever reaches a measuring surface or a third comparator breaks off the scanning operation. <IMAGE>
Patent DE-3103549-A1 (DE)
Title: Energy-saving building heating
IPC: F24D5/10
Filed: 1981-02-03
Abstract: The invention relates to a building heating by means of a heat pump of the air/air or air/water system, the outside air which serves as a heat source being sucked in by way of interspaces between the supporting wall and front-hung façade and between the roof boarding and roof covering. The heat pump working with outside air as the heat source has the disadvantage that its heat capacity decreases with a falling outside temperature, that is to say with an increasing heat demand of the building. In order to satisfy the heat demand of the house completely, even on the coldest of days, the heat-pump apparatus becomes very large and correspondingly expensive. Since the temperature difference between the heat source and heating temperature is critical for the efficiency (performance number), the efficiency is appreciably impaired at low outside temperatures, that is to say with a large heat difference. As a result of the present invention, a good efficiency of the heat pump is achieved even when the outside-air temperature is low. As a result of the suction of outside air by way of gaps between the building walls and the roof, heat which is otherwise lost as transmission-heat loss is transferred to the air. The preheated air is cooled to slightly below the outside-air temperature on the evaporator of the heat pump and is blown into the open. The transmission heat given off by the surrounding walls is thereby absorbed virtually completely by the air stream. As a result of the higher temperature of the air, the temperature difference between the heat source and the heating temperature is reduced and the performance number of the heat pump is improved. Heat losses (for example, ventilation losses) going beyond this are covered by the slight cooling to below the outside temperature. The heating of the rooms takes place by means of low-temperature surface heating or by means of direct air heating. <IMAGE>
