Title: Breeding and treatment device for bees
Inventor: BUSCHACK WILHELM
IPC: A01K49/00
Filed: 1988-09-09
Abstract: The bees require 35@C in order for their nest to hatch. Since, however, the bees faithfully pursue tasks in order to preserve their species, this primarily also means consumption of food and great activity. On the other hand, the bee is being done great harm by the worldwide occurrence of the Varroa mite (Varroatose). This parasite lays its offspring-bearing eggs in the brood cells of the bees and develops with the bee in the concealed nest so that when the young bee hatches the Varroa parasite also hatches at the same time. The bees have no opportunity to get rid of the parasite themselves so that without external aid whole bee populations die. Elimination would be possible if there were no honey and wax which become toxic and are hence unsuitable for human consumption. By virtue of the device of this invention it is possible to allow concealed brood combs of the bees to hatch in the breeding and treatment system by keeping to rational technology, observing a good latent period and taking into consideration the nascent life and the division of labour between nature, bee and development. As the Varroa mite hatches at the same time as the bees hatch it is possible to use techniques in order to carry out treatment in the system according to the invention by biotechnological means - thermally and naturally, without obtaining damaging residues in the honey and wax. So that the bees are not born into a technical world... Original abstract incomplete. <IMAGE>

Patent DE-3834595-A1 (DE)
Title: Device on film processing machines
Inventor: WILKE HORST
IPC: G03D13/00
Filed: 1988-10-11
Abstract: The invention relates to a device on film processing machines for generating control signals when film strips or film plates are present or not present in a feed slot. Control signals of this type are important because in modern processing procedures the individual steps are subject to an exact control with a precise temperature tracking and, in addition, the preparation and regeneration of baths are also to be executed automatically. The start and the end of a film and the film width are to be detectable. Previous systems which had mechanical sensors or reflected-light barriers had the inherent risk of damaging the film mechanically or the risk, at least in the case of infrared-sensitive films, of strips forming due to the light of the light emitting diodes. Mechanical sensors or switches can furthermore be corroded by the processing chemicals. These disadvantages are removed according to the invention in that compressed air is blown transversely through the feed slot onto NTC or PTC conductors which are cooled when no film is present. An inserted film interrupts the cooling. The rise in temperature causes a change in current which can be easily measured and is used to generate a control signal.

Title: Circuit arrangement for detecting errors in the transmission of data between a transmitting device and a receiving device
Inventor: KOCK ERNST JOSEF DR
IPC: H04L1/00
Filed: 1988-10-26
Abstract: In a receiving device (EM) having a number of receivers (E1 to Ep), which are supplied with different proportions of the data containing the entire useful information (NK), these transmission data are subdivided into subsets (NT1, NT2...NTp), one subset of which is sent as intersection (SM) to each receiver (E1 to Ep) and one further subset (NT1, NT2... or NTp) of the remaining subsets is in each case individually sent to each receiver (E1, E2, ... or Ep). To each receiver, a parity generator (PG1 to PGp) is allocated which in each case generates from the individually supplied useful bits one parity bit (e.g. PB1), all of which together are logically combined to form a sum parity (SP) at the receiving end. At the transmitting end, the parity (PK) derived from all K useful bits (NK) is corrected by a signal (PC) which can only be derived from the parity (PSM) of the intersection bits in dependence on the number of receivers (EN), in such a manner that when the corrected signal (CP) does not correspond to the sum parity (SP) at the receiving end, an error signal (ER) is generated. <IMAGE>

Patent DE-3933809-A1 (DE)
Inventor: WOLF BERND M
IPC: C10B57/02
Filed: 1989-10-10
Abstract: In a process for the disposal of toxic and/or infectious waste, especially highly halogenated solids, plastic containers, hospital waste and the like, to recover useful substances and render inert non-recyclable and unoutgassable residues, outgassing by the pyrolytic process is used, with air excluded and a reduced oxygen content, followed by the direct incineration of the distillation gases obtained from pyrolysis or their cracking to form a pyrolysis separation gas. The waste to be disposed of is inserted in an autoclave (2), partially outgassed there for a period of 20 minutes to 6 hours at about 250 to 320  DEG C in an initial outgassing stage, then cooled and made into a granulate or pellets measuring from 1 to 50 mm, which are subsequently treated by the pyrolysis outgassing method in a second outgassing stage at a temperature of 550 to 600 DEG C. This generates distillation gas which is separated from the residues, like carbon, ash, heavy metal particles and other components. The liquid partial outgassing intermediate products, like oil and/or coal tars, produced in the autoclave (2) are taken to the second outgassing stage, while the distillation gas separated off in the first outgassing stage in the autoclave (2) is taken off and added to the stream of distillation gas from the second outgassing stage.

Title: Control system for refrigeration circuit - prevents flow of liq. refrigerant into compressor
Inventor: BUCK WILHELM DR ING
IPC: F25B41/06
Filed: 1989-10-19
Abstract: The refrigeration circuit has a compressor (6) which delivers the refrigerant in vapour form to the condenser (5). The liq refrigerant then flows through the flow control valve (9) to the evaporator (3). The evaporator is connected by a pipe (7) and duct (71) to the inlet of the compressor. In order to prevent any drops of liq refrigerant flowing into the compressor a detector (11) is installed in the duct. This detector (11) is maintained at a temp above the evaporation temp of the refrigerant. The detector (11) is thermally insulated from its surroundings so that when a drop of refrigerant falls on the det-ector (11) the refrigerant is evaporated and the temp of the detector falls. This falling temp generates a signal which controls the flow control valve (9). USE - Refrigeration circuit.
