Title: Superconducting multiple resonator microwave filter - has strip line in cryostat, with central conductor of superconducting material
Inventor: MINET ROGER
IPC: H01P1/20
Filed: 1974-02-20
Abstract: The central conductor is placed between two dielectric foils and metal earthing plates of a superconducting material. The resonator frequency depends on the strip line length. Rectangular dielectric plates taper at one end, and can slide along paths which cross the strip line elements. They are externally remotely controlled. The strip line central conductor consists of sections about half a wavelength long at the filter centre frequency. They are coupled with each other through slots. Each of these sections is bent at a right angle, and the central conductor, together with the dielectric foils and earthing plates, forms a rectangular capacitively slot coupled filter with a strip transmission line. Strip line sections intersect the paths of the above plates.

Title: Domestic space heating system - utilises residual heat in domestic hot water run to waste in drains
Inventor: STOEVER ROLF
IPC: F24D17/02
Filed: 1974-08-12
Abstract: The waste pipe carrying water from the outlets of sanitary fittings terminates with an inlet pipe into an insulated storage vessel. The vessel has a high level outflow which takes excess water to the drains. A bypass round the vessel with a thermostatic valve ensures that cold water in the waste pipe goes straight to the drain. Space heating is provided by a heat pump which uses river water as a source. A three way valve allows all or some of the river water to pass through a heater coil immersed in the storage vessel before going to the heat pump evaporator. This raises the temperature of the heat pump source and therefore its output.

Title: Two stage column scanning of data - initial stage provides filtering of numerals prior to final recognition scanning
Inventor: RASEK EDUARD DIPL ING
IPC: G06V30/146
Filed: 1974-09-20
Abstract: The calculation of the charge to be made to a subscriber for a telephone call is determined by photographing the readout of a charge counter. Automatic accounting is based upon electronic scanning of the numerals recorded using a character recognition system. The resolution of the recorded information is likely to be fairly low, and an initial scanning procedure is executed to eliminate boundaries that are of no consequence. The net effect of the initial scanning procedure is to produce a classified and digitised image of the information. At the same time the initial scanning procedure defines limits for the final scanning stage that generates the required character recognition data. The initial process corresponds to a filtering process.

Title: Test tube for blood specimens - quartz wadding or granules used as coagulating substance
Inventor: HAEBICH HANS JOACHIM
IPC: G01N33/487
Filed: 1974-11-13
Abstract: The blood specimen test tube is designed to receive a coagulating substance. No additions or impurities arise which could disturb or falsify any clinical-chemical or serological examinations in this case where the coagulating substance is quartz. Commercially available quartz is sufficiently pure. In a preferred embodiment the quartz is in the form of wadding since a plug from it gives a large surface area per unit weight and therefore comes into contact with a large volume of blood. Threads of the wadding (2) adhere to the side walls of the tube (1) which, in view of the light weight, is sufficient to prevent it falling to the bottom. Alternatively, the quartz is in the form of finely granulated powder (5).

Patent DE-2551374-A1 (DE)
Title: Filter system for furnace gases - having saturation water cooler with bypass to give temp. above dew point
Inventor: BUTZ HEINZ
IPC: B01D46/44
Filed: 1975-11-15
Abstract: Dust removing plant for hot furnace gasses uses a dry filter preceeded by a cooler. The latter consists of a saturation spray cooler which cools part of the gas stream down to a temp. below its dew point. There is a controlled bypass around this to mix some hot gas with the output from the cooler so that the gas entering the filter is always above its dew pt. In general the final temp. should be at least ca. 90 degrees C or esp. in the range 120 to 250 degrees C. Any particles separated in the cooler are added to the dry dust from the filter to wet it out and granulate it. Used esp. for treating hot gases containing dust exhausted from furnaces. A major problem with such gases if cooled to below the dew pt. is their acidity causing corrosion problems in coolers etc. Also surface coolers are prone to blockage. Some cooling is necessary because filters will not accept the hot gas direct. The process described gives a simple method of ensuring a gas stream above the dew pt. yet cool enough to filter without blockage or corrosion problems in the cooler.
