Title: High quality video tape magnetic film implanting device - ensures even magnetic film on tape and is suitable for mfg. multiple layers
Inventor: TAMAI YASUO
IPC: G11B5/845
Filed: 1977-08-09
Abstract: The mfg. head and its attachments for implanting an even film of magnetically oriented material on a plastic carrier for mfg. high quality magnetic tape, particularly video tape. The device is suited to multiple layer implantation in an alternative form and gives even film quality. The basic unit consists of a prism shaped head (3) contg. a shaped slot or nozzle (5) and a small internal reservoir (4) through which the liquid magnetic material (1) is fed from above. The nozzle is shaped to prevent a vena contracta forming in the shaped column of material which falls through it and travels between two guides (7a, 7b) on to a plastic carrier tape (9). Magnetic orientation is provided by coils n8) and in some cases auxiliary coils (13) which in disturbance is minimised by a shield (11).

Title: Contactless temp. control for sanitary installations - uses optical transmitter and receiver and signal switching device for different appliances
Inventor: DOLDERER ERICH A
IPC: H03K17/94
Filed: 1977-08-10
Abstract: The temp. controller consists of a panel-mounted sensor comprising a moulded housing fitted with an optical transmitter (4) and receiver (3). The inlet/outlet windows of the transducer are on the underside of the moulded projection so that the light beam, which is transmitted vertically downwards can be reflected from an object, e.g. a hand (6), back to the detector. The signals from the light detector are amplified and passed to an amplitude discriminator. A control signal can thus be derived which is proportional to the proximity of the hand to the detector housing since the amount of reflected light will vary in proportion to the distance. The device can be used to control the water temp. of sanitary installations and the like.

Title: Double jet air cushion paper strip dryer - has heads facing opposite directions, each with block between arms of H-shaped housing
Inventor: OGAWA TADAO
IPC: F26B13/20
Filed: 1977-08-17
Abstract: The air cushion arm for e.g. strip paper, uses two jets (1) under and over which the strip passes successively. The first facing downwards, and the second facing upwards. The casing is approximately H shaped, with a gap at the centre of the cross piece (4). Between the bottom edges of the side arms (6) is a block (2), leaving a gap each side, between the edges and the block. This leaves a pressure zone (P) between the outer surface of the block and the travelling strip, holding the strip away from the surface. The side arms slope an acute angle to the vertical centre line of the jet housing. The sizes of the gaps and the chambers inside the housing are specified.

Title: Foam glass for use in solar collectors - as insulating and constructional material
Inventor: BEYER UWE DIPL CHEM DR
IPC: F24J2/51
Filed: 1977-09-08
Abstract: Foam glass is used as a heat-insulating and constructional material for solar collectors. The foam glass may be made from glass powder, volcanic glass, basalt and/or waterglass. Solar collectors constructed from foam glass as load-bearing material with a heat-insulating function are also claimed. The materials are completely resistant to temps. of 550-600 degrees C, which are above those encountered even in high-temp. collectors. They have higher mechanical strength than organic foams, and can be made with a glazed, closed-cell surface, and can function both as the load-bearing housing and thermal insulation of the collector.

Title: Hot water supply circuit - employs inner and outer recuperator coils at chimney for preheating water in auxiliary tank
Inventor: FISCHER WILFRIED
IPC: F28D21/00
Filed: 1977-11-14
Abstract: The central heating system has a duct between the boiler and the chimney with a coil inside the duct, and another coil around the outside of the duct. Thus both coils, which are in series are heated by the combustion gases. These coils are included in a circuit in which water is circulated to supply water to an auxiliary storage tank connected to the cold water supply. This circulation is controlled by a thermostat so that the water can be heated up to 42 deg.C and used directly. For higher temperatures, this water is fed to the main hot water tank before use.

Inventor: SLOYAN JEROME J
IPC: F01K25/08
Filed: 1977-12-19
Abstract: A Rankine cycle power plant system using propionic acid (I) as working fluid is new. The system, which is pref. sealed to prevent loss of (I) which can then be used repeatedly, comprises a boiler and an engine connected by a feed line and a return line. Opt. the return line includes a preheater tank and an air-cooled condenser, pref. thermostatically controlled.

Title: Pressure vessel penetration and seal for instrumentation ducts - with couplers permitting duct removal and temporary cover to vessel penetration
Inventor: SULIC MILAN DIPL ING
IPC: G21C17/10
Filed: 1978-04-24
Abstract: A reactor pressure vessel has a tubular instrumentation duct passing out through the vessel bottom. The duct is surrounded by a pipe which passes through an outer pressurised duct welded to the pressure vessel shell and forming the pressure boundary to the vessel. The pipe is sealed in the pressurised duct at a sealing point outside the pressure vessel shell. Below this sealing point, which comprises a screw connection, each instrumentation duct has a coupling point. When the instrumentation ducts are to be replaced, they are disconnected at this coupling point and a temporary cap is placed over the coupling points and sealed to the end of the duct, pref. by screwing into it at a screwed connection coaxial with the screwed connection forming the seal. The coupling points in the instrumentation ducts may be conventional self-sealing couplers. Used esp. for a boiling water reactor. More specifically for non-electrical instrumentation connections, such as those for measuring the coolant pressure. The instrumentation ducts can be replaced without draining coolant.

Title: Ceramic clap boards for covering walls and/or roofs - where pair of boards joined by longitudinal webs are continuously extruded, then cut to length and baked
Inventor: EICHHORN ROLF
IPC: B28B3/20
Filed: 1978-11-27
Abstract: The starting material is a ceramic which is completely resistant to frost and other climatic conditions, and is pressed in a known way used for mfg. split tiles to form a double flat strand where two flat continuous panels are joined back to back by webs running in the direction of travel of the pressing or extrudate out of the press mouth. The thickness of the two panels is reduced by increasing the size of the webs; and one edge of each panel may be bent during the pressing operation. When the pressing or extrudate leaves the press, holes or zones of weakness are pref. provided in the bent edges of the two continuous panels. The thickness of the panels of boards can be reduced in comparison with conventional boards, but high strength is still achieved and the ceramic may possess special desired colours.

Title: Turbo-molecular vacuum pump with two=part rotor spindle - has solid lubricant ejected from spindle interior towards top and bottom bearings
Inventor: PFAFF HANSEN DR
IPC: F04D19/04

Patent DE-2901148-A1 (DE)
Title: position control for electron beam welder - uses X=rays emitted during special measurement interval by beam travelling closed path intersecting weld direction
Inventor: MOENCH CLAUSPETER DIPL PHYS
IPC: G05D3/12
Filed: 1979-01-12
Abstract: The welding process is punctuated by brief measurement intervals in which the electron beam (14) is deflected and made to trace out a closed path (22) spanning the seam (12) being welded (18,20). The beam interacts with the workpiece (10) and causes X-rays (28a) to be emitted from its surface. These X-rays are detected by X-ray detectors and the result used to control the position of the electron beams. The X-ray detector's output is a function of that length of any one section of the closed path travelled by the beam that lies between a reference position and the X-ray detector's aperture limit intersecting the closed path. The detector's aperture limit (i.e. area of measurement limit) is parallel to the feed direction (X). The associated measurement area lies on the side of the measurement area limit facing the processing zone. The detector's output is proportional to the distance between a reference axis (electron gun's axis) and the point where the closed path intersects the measurement area limit.

Title: Engine with fuel flowmeter in pump inlet - returns excess fuel downstream of meter after cooling to avoid temp. affecting reading
Inventor: WABEL KARL DIPL ING
IPC: G01F1/12
Filed: 1979-06-21
