Title: Generation of radiation pattern on specimen - converts beam from source into parallel beams displaying pattern of masker
IPC: H01J37/30
Filed: 1976-11-15
Abstract: Instrument generates a radiation pattern on a prepared specimen. The radiation is derived from a source and there is a mechanism for adjusting the prepared specimen inside the instrument, whilst a detector indicates the amount of radiation penetrating the prepared specimen on a calibration marking. The instrument (1) displays a masker (2) on the prepared specimen (3). Electron beam 75) emanating from the source (4) is converted to parallel beams (8) via a condenser lens (6). The pattern (7) of the masker is displayed in accordance with a shadow projection in the ratio of 1 to 1. The calibration marking (27) is on the opposite side of the source. This marking is also radiated with a beam (28) from a source located on the same side of the prepared specimen.

Title: Door mounted aerosol spray actuator - has strip and belt can mounting with steel strip tongue depressed onto button by door frame
IPC: B65D83/16
Filed: 1977-01-07
Abstract: The mechanism automatically actuates an aerosol spray can. It is fixed to a door and door frame so as to eject a spray each time the door is opened or shut. The mechanism can have a belt of steel strip riveted to another such strip, so that the can can be fitted in place without having to touch it by hand. A shaped steel strip tongue opens the valve when in contact with the door frame. A sliding piece with supporting heel can be included, to allow adjustment of the mounting to suit the can length.
Patent FR-2341740-A1 (FR)
IPC: C23C14/08
Filed: 1977-02-21
Abstract: Such a component, e.g. a blade of turboengines, consists of an inner base material and a material layer applied to the base material in a sputtering process. In this process, the component (1), a moulding (2) of the material to be applied, and an anode grid (4) are introduced into a vacuum vessel (3). High-frequency alternating current is employed to detach atoms from the moulding (2) and use these to coat the component (1); as a result, an extremely smooth, dense and robust material layer is achieved even on complicated components.

Title: Connection between gas insulated HV line and oil filled transformer - uses intermediate gas filled space to form hermetically sealed joint
IPC: H01F27/04
Filed: 1977-02-14
Abstract: The connection connects a gas-isolated (eg SF6) tubular HV line to an oil-filled transformer. A hollow cone (16) is fixed and sealed to the outside of the transformer housing (24) and encloses the feedthrough (22) from the transformer's internal connection. The HV line's conductor (14) extends through the apex of this cone and connects with the end of the feedthrough. The conductor's casing (10) mates with the flange around the base of the cone. The space inside the cone is hermetically sealed and filled with the same isolating gas as the HV line and at approx. the same pressure. The oil pressure inside the transformer is less than the gas pressure (i.e. is roughly atmospheric).

Title: Control circuit for electric motor of dental drill - uses semiconductors to produce three=phase current from DC source
IPC: A61C1/06
Filed: 1977-07-13
Abstract: The dental drill is driven by a three phase stator wound electric motor. The motor operates on a dc supply with an inverter consisting of several semi-conductors connected to certain of the motor phase windings and to a frequency variable signal pulse generator by a switching circuit. This circuit enables one pair of semi-conductors to be blocked whilst another pair becomes conducting. This in turn supplies a three-phase current to the motor to allow it to rotate in one direction at a speed proportional to the frequency of the signal pulse. A voltage regulator is also connected to the circuit and enables the dc voltage across the motor to be varied over a pre-determined range depending on the frequency of the signal pulse. The max. turning moment is obtained at the relatively low speed of 5000 r.p.m.

Title: Nutritious medium for fodder yeast mfd. from manure, etc. - by hydrolysing conc. suspension and adding back decanted liq. fraction
Inventor: ZAITSEV K P
IPC: C12N1/16
Filed: 1977-09-05
Abstract: The process for converting liq. manure without stable litter into a nutritious medium for the growth of microorganisms esp. yeasts as a source of proteins and vitamins. The manure is sepd., e.g. by centrifuging into a clarified liq. fraction and a conc. suspension. The liq. fraction is sterilised and the conc. suspension is heated and then hydrolysed in the presence of a mineral acid as catalyst, e.g. H2SO4, the hydrolysed prod. then being neutralised. Prod. is treated, e.g. by ultraviolet irradiation to eliminate noxious, volatile, impurities, and is then cooled. Before neutralisation, the sterilized liq. fraction is admixed with the hydrolysed prod. The neutralised prod. is pref. desludged, e.g. via a decanting centrifuge. Used in mfr. of fodder yeast from pig manure, poultry droppings, waste from the futs of slaughtered animals in large abattoirs and similar organic refuse. Adding back the clarified liq. fraction greatly increases the yield of nutritious prod. while reducing mfg. costs. For example, a pig farm raising 108,000 pigs per year can produce 2,000 tonnes p.a. of fodder yeast to make up about 5,200 tonnes of fodder which represents a 10% saving on the fodder bill. The neutralisation process requires 20-80% less alkali when the liq. fraction is added back.

Title: Chipboard panel lining process - with difference in temperature preset at each side of panel before pressing paper to hottest side
Inventor: CLAROUS BERTRAND
IPC: B29C63/00
Filed: 1977-11-22
Abstract: The process is used to apply a thermohardening lining to one side only of a chipboard panel. The operation is carried out in a single or multi-stage bed press using heated platens.

Title: Austenitic iron-nickel-chromium-aluminium-rare earth alloy - for forged oxidation resistant resistance heaters
Inventor: DAVIDSON JAMES H
IPC: C22C38/40
Filed: 1978-01-17
Abstract: The alloy has the compsn. (by wt.) 20-60% Fe, 20-60% Ni, 15-27% Cr, 4-6% Al and 0.001-0.1% of one or more of rare earth metals (including yltrium and scandium). The Fe, Ni and Cr contents lie in a region shown in a ternary diagram for alloys contg. 5% Al at 900 degrees C. The alloy has a resistivity of >100 mu OMEGA cm. It has a higher oxidation resistance than Ni-Cr-Al-Y alloys because the Fe prevents spalling of protective oxide films; this Fe addn. does not reduce creep strength as long as the structure remains austenitic. The alloy is forgable since the rare earth addn. compensates for unfavourable effects of Al, has better toughness, creep strength and oxidn. resistance than ferritic alloys and has a higher temp. of use than known austenitic alloys.

Title: Oxidation of organic sulphide(s) to corresponding sulphone(s) - using hydrogen peroxide, a carboxylic acid and a mineral or sulphonic acid catalyst
Filed: 1978-03-24
Abstract: An organic sulphide is oxidised to the corresponding sulphone with a mixture of H2O2 and a carboxylic acid in the presence, as a catalyst, of a mineral acid or an organic sulphonic acid. The process gives higher yields of sulphone (e.g. 66-90%) than are obtd. in the known process performed in the absence of acid catalyst (e.g. 34%) with less formation of sulphoxide by-product (generally is approx. 0.1% if a sufficient quantity of acid catalyst is used as opposed to e.g. 15% in the absence of a catalyst). The sulphone products have a wide vareity of uses e.g. as insecticides, miticides and nematocides. In a typical example, 2-methyl-2-methylthio-propionaldehyde O-(methylcarbomoyl)-oxime is oxidised to the corresp. sulphone using H2O2 and formic acid in CH2Cl2 contg. concd. H2SO4.
