Title: High speed counter with programmable frequency division - uses auxiliary counter stage to minimise delay associated with clock inhibition during preset cycle
Inventor: SOMMER BERND DIPL ING
IPC: H03K23/66
Filed: 1976-09-30
Abstract: A high speed clock controlled counter includes a facility for programming a specific frequency division ratio. The basic frequency division is provided by a binary counter (2) that is coupled to a selector (1) to apply a preset condition. The counter outputs (QA--QD) are coupled to a decoder (3) that recognises a specific combination. At the end of each cycle the preset is enabled (L) and the clock input (20) inhibited. In order to speed up the counter cycle, an auxiliary counter (4) is included. This counter does not influence the preset cycle, but minimises delay associated with inhibition of the clock input. A control pulse generator (7), preset pulse generator (6) and clock gate (5) complete the system.

Title: Aerating tunnel supports for compost heap of decomposing waste - comprising trestles standing on pallets with perforated tops
Inventor: WILLISCH HANNES
IPC: C05F17/02
Filed: 1977-03-18
Abstract: Supports of parent patern are for a compost heap in which household rubbish, drainage sludge, etc. are decomposed cleanly to produce an dreanic fertiliser. The supports form longitudinal tunnels in the base of the heap communicating with vertical chimney shafts to produce continuous oxygenation. The walls of the supports are perforated to allow circulating air to pass thro. In addition, the supports are carried on pallets which are located between the supports of two adjacent tunnels. The top platforms of the pallets are perforated to allow air pass freely through i.e. pref. in the form of a grill or screen construction. The perforated pallet tops assist aeration and speed the decomposition process. The possibility of unventilated dead spots, together with the danger of offensive putrefaction, is thus eliminated.

Title: Real and imaginary components measurement - is for output signal and involves sampling input voltage peaks and zero crossings
Inventor: GERSDORFF MICHAEL VON ING GRAD
IPC: G01R27/02
Filed: 1977-05-24
Abstract: The signal is the output of an element or system which can be determined by its frequency response.

Title: Condition monitoring system for PBX - collects information from all de-centralised devices before evacuating
Inventor: KRAUSS JULIA
IPC: H04Q3/54
Filed: 1978-03-28
Abstract: The condition monitoring system has its central control fetching interrogation information from the decentralised devices and entering it into storage cells unevaluated. The cells are assigned one to each decentralised device and are selected via addresses. The central control only evaluates this stored information after it has been collected from all decentralised devices. Only then does the central control initiate events resulting in information being sent back to the decentralised devices. Information evaluation is given a lower priority by the central control than information collection from the decentralised devices.

Title: Hydrogen sulphide removal from gases - with a soln. contg. sulphuric acid, copper sulphate and ferric sulphate; and recovery of molten sulphur
Inventor: YAMADA MINORU
IPC: C01B17/027
Filed: 1978-04-29
Abstract: Hydrogen sulphide is removed from a gas by passing the H2S-contg. through an absorbing soln. contg. 50g/l of sulphuric acid, copper sulphate and ferric sulphate.

Title: Battery charging system for motor vehicle - has three=phase excitation for generator to ensure immediate availability of supply
Inventor: RAGALY ISTVAN DIPL ING
IPC: H02J7/16
Filed: 1978-09-05
Abstract: The battery charging system has a 3-phase generator with an output winding on its stator and an excitation winding on its rotor. A voltage controller is connected to the generator's brushes, which slide over slip rings on the generator's shaft connected to the excitation winding. The latter receives a 3-phase current from a static inverter supplied largely from the battery being charged by the generator. The excitation current for the generator is therefore 3-phase. The advantage lies in power being available even at low generator speeds. The max. required speed of the generator can also be reduced.
