Title: Table tapping device for dispensing beer
Inventor: CREMER KARL LUDWIG
IPC: B67D1/06
Filed: 1981-12-30
Abstract: For dispensing beer, use is generally made of stationary counter installations with beer tapping devices. For low requirements, beer tapping devices are also used, which have tins filled with beer. Lastly, it is also usual to tap the beer directly from a beer barrel. In order on the one hand to avoid the great expense for counter installations but on the other hand to be able to have beer ready for average requirements and at the same time to make the beer storable for a longer period also, an all-round closed and thermally insulated housing is proposed, which can be erected freely on a support and on the operating side of which one or more tapping cocks are provided, which can each, inside the housing, be connected to a beer can by means of a beer pipe connection, each beer pipe connection being connected to a common carbon dioxide body and an electrically operated cooling device being accommodated inside the housing.

Patent DE-3202593-A1 (DE)
Title: Improved heat pump
Inventor: LAUDE FRITZ
IPC: F25B30/02
Filed: 1982-01-27
Abstract: Heat pumps serve to extract thermal energy from the air and from flowing water or groundwater. In practice, this is a reversal of the known refrigerator principle. The range of application of air/water heat pumps is small, in practice only 38% of the heat required can be extracted from the air, because the efficiency is adequate only within a small temperature range. However, 62% of the thermal energy is required in the range from -20 DEG  to +2 DEG , and given a possible efficiency of  epsilon  = 1.66 there is no longer any advantage. The reasons are to be sought essentially in that the pressure relationships in the compressor assume unfavourable values, while in the case of multistage compression more favourable values arise, as can also be seen from the known energy p-h diagrams. Again, in the case of multistage compression the stage losses can be resupplied to the circulation process and, in addition, individual stages can - as a function of temperature - be connected or disconnected, thus enabling a higher efficiency.

Title: Simple spiral outside stair
Inventor: STEFAN HEINRICH
IPC: E04F11/116
Filed: 1982-03-09
Abstract: A simple spiral stair, in particular outside stair, is described, the individual steps of which are constructed as prefabricated steps. For the construction of the steps, two embodiments are proposed. In the first embodiment of a step, the tread plate and the riser plate are designed in separate parts; in the second embodiment of a step, the tread plate and the riser plate form one part. The material of the steps is concrete with an inner reinforcement. In both embodiments, the steps, assembled as a simple spiral stair, can overlap one another to a greater or lesser extent, so that a long or short winding can be produced using the same prefabricated steps. Rectangular steps which are known in their outward form, but are constructed in accordance with one of the embodiments according to the invention form the first step and the last step of the winding. <IMAGE>

Title: Power supply in active peripheral devices
Inventor: RAAB KLAUS ING GRAD
IPC: G06F1/26
Filed: 1982-03-16
Abstract: The connecting lines existing for data transmission are also used for supplying the active peripheral devices with power. The supply voltage is set in the central processing unit by means of commands from the peripheral device. Resetting and tolerance logic generates the commands. Disconnection of the peripheral device is detected in the central processing unit and allows the supply voltage to drop to a minimum value. The arrangement allows non-standardised line lengths to be used between the central processing unit and peripheral device in the case where the latter is centrally supplied with power. This makes it possible to implement commutation of a central processing unit to various peripheral devices in a simple manner.

Title: Method and digital integrated circuit for generating electrical oscillations within the audio-frequency range
Inventor: MICHEL ADOLF DIPL ING
IPC: G10H5/12
Filed: 1982-05-12
Abstract: The method enables electrical sine wave-like oscillations to be generated from square wave oscillations without steep low-pass filters for each octave in electronic musical instruments. Another advantage of this method consists in the possibility of carrying out transpositions of the overall tuning of the electrical musical instrument without changing the filters. These possibilities are combined in an integrated circuit which contains other additions for building up tonally expanded sound creations.
Patent DE-3227264-A1 (DE)
Title: Arrangement for monitoring a plant actuated by pressure medium
Inventor: BLECKMANN HANS-WILHELM
IPC: B60T17/22
Filed: 1982-07-21
Abstract: For monitoring a plant actuated by pressure medium, the periods for which the device which replenishes the pressure reservoir is switched on and switched off are compared with tolerance limits depending on the system, with additional consideration of the actuations of the pressure-using unit. Those longest and shortest times are used as the tolerance limits, which times result for the periods during which the device is switched on and switched off in the case in which the pressure-using unit is not actuated. For consideration of the actuations of the pressure-using unit during the periods when the device is switched on and switched off, only the possible extreme conditions are evaluated, i.e. the maximum and minimum volume used per actuation, and also the number of resulting actuations, so that the actual volume used does not need to be measured and the monitoring is restricted only to time measurements.

Title: Hose pump especially for the pumping of concrete
Inventor: BENDER HORST
IPC: F04B43/12
Filed: 1982-11-26
Abstract: The invention proceeds from a concrete hose pump in which a hose is led in a U-shape through a cylindrical housing having a vacuum, the hose being compressed by means of two rotatable pinch roller carriers preferably provided with elastically covered pinch rollers in repeated cycles against the inner wall of the housing, likewise preferably elastically covered, thereby progressively sealing off the hose cross-section. The elastic coverings are intended to permit the sealing embedding of larger stones in the area of maximum pinching, whilst the vacuum is intended to facilitate the return of the hose into its normal shape after pinching. Although the coverings permit adequate sealing they cause no changes in the repeated overstretching of the hose in the pinching area. The setting up of a vacuum requires a second pump, the weight of which together with that of the covering material adversely affects the mobility of the pump. The vacuum and the insulating effect of the housing covering lead to destructive temperature increases in the hose. In order to avoid these disadvantages it is proposed to design the housing open to the ambient atmosphere, to dispense with the elastic covering of the pinch rollers and the housing wall, to make the hose of such a thickness that the wall thickness is at least half the maximum grain size and to ...

Title: Housing for a tripping relay, especially for the tripping relay of a residual current device
Inventor: ZIELASKO HORST
IPC: H01H71/32
Filed: 1982-12-27
Abstract: The invention relates to a housing for a tripping relay, especially for the tripping relay of a residual current device (earth-leakage current circuit breaker).

Patent DE-3300531-A1 (DE)
Title: Method for controlling access to a time division multiplex information transmission path
Inventor: KILLAT ULRICH DIPL PHYS DR
IPC: H04L12/64
Filed: 1983-01-10
Abstract: An 8-kHz frame frequency with fixed allocation of the channels in the frame is suitable for the transmission of voice data in time division multiplex, whereas a fixed allocation of this type is very unfavourable for the transmission of data packets. Therefore, according to the invention, the frame is subdivided into a plurality of groups, in each case with the same number of words, and each group either contains only narrowband channels for voice data transmission or is associated with the high-speed channel. A signalling word, which always contains a unique bit pattern, for example with top priority, for groups with narrowband channels, is allocated to each group. If a subscriber station wishes to gain access to a word group in the high-speed channel, it transmits its own address and, where appropriate, priority data in a signalling word. If this bit pattern is received without interference, the subscriber station immediately seizes the allocated group of words in the high-speed channel for the transmission of a data packet. Allowance can be made for individual subscriber station priorities in different ways. If the bit pattern of the groups with narrowband channels receives top priority, these channels are automatically protected against access as a high-speed channel, and a central unit can flexibly increase the number of narrowband channels by transmitting this bit pattern in the signalling word of a further group. <IMAGE>

Title: Text-capable digital telephone station
Inventor: KAMMERL ANTON DR
IPC: H04M1/247
Filed: 1983-03-02
Abstract: The invention relates to a method for multiple use of the dialling keys of a text-capable telephone station with a display, where a specific stored code is assigned to each function of the dialling keys. In addition to the respective digit, the dialling keys contain a plurality of letters for text creation. The input of the text to be prepared and subsequently transmitted is intended to be as simple as possible. This is achieved in that, when a higher-order key is pressed, symbols appearing on the display cyclically in a time pattern are visible which are allocated in their sequence to the individual functions of each dialling key and that, when a dialling key is subsequently pressed, the function of the corresponding dialling key is transferred from a read-only memory to a main memory and appears on the display at the first free position which is assigned to the symbol in the time pattern. Since the higher-order key needs to be pressed only once per text, only one key needs to be pressed and released at the correct time for each function.
