Title: Improvements in indicating devices for weighing scales
IPC: G01G23/20
Filed: 1923-02-26
Abstract: 217,957. Marks, E. C. R., (Toledo Scale Co.). Feb. 26, 1923. Indicating - mecha nism; computing - apparatus.-In a weighing scale the index for co-operating with the indicating chart consists of a thread or a pair of threads of fibrous material maintained in a taut condition by resilient holding means. As applied to a weighing scale having a computing drum 2 the reading line 15 of braided silk is attached at each end to a telescopic member 13, Fig. 4, pressed outwards by a spring 17 so as to maintain the reading line in a taut condition. The telescopic member has a boss 11 fitting into a hole 9 in a slotted clip 7 adjustably secured to the price plate 5 or to the frame of the chart housing. A slit 10, Fig. 2, leading from the hole 9 to the edge of the clip allows the telescopic member 13 and the reading line readily to be removed from, or inserted into the clip. When two reading lines are employed to avoid errors due to parallax, the second reading line is secured by similar clips at the other side of the plate 5. At the rear of the machine where no price plate is mounted, the clips for the reading line are secured to the frame of the chart housing.

Title: Graft copolymers and process for producing them
IPC: C08F290/02
Filed: 1972-02-08
Abstract: A copolymerisable long-chain monomer is prepared. The process of preparation comprises subjecting an olefinically unsaturated, anionically polymerisable monomer to an anionic polymerisation in the presence of a polymerisation initiator to form a monofunctional living polymer having a uniform molecular weight within the range from 5000 to 50 000 and terminally blocking (tipping, capping) the living polymer with a halogen-substituted epoxide or a halogen-substituted vinyl compound which are each free of silicon atoms with the elimination of an alkali metal halide. The resulting macromonomers with polymerisable, olefinically unsaturated end groups are then reacted with a second, unsaturated comonomer to form a graft copolymer, the latter comonomer forming the backbone of the graft copolymer and the macromonomer the side chains.

Title: Fuel feed control device for internal combustion engine
IPC: F02M51/08
Filed: 1973-02-07
Abstract: 1427995 IC engine fuel injectors HITACHI Ltd 7 Feb 1973 [3 March 1972] 5943/73 [Also in Divisions H1 and H3]  The opening and closing times of an electromagnetically opened I.C. engine fuel injection valve are reduced by providing the electromagnet with at least two coils and providing control means so arranged that at least one of the coils is capable of producing magnetic flux in such a direction as to close the valve, and at least one other, or the other, coil is capable of producing a magnetic flux which is only sufficient to hold the valve open once it has been opened (i.e., a holding flux), the control means being so arranged and connected to the coils that when the valve is to be opened, a holding current can first be passed through the one or the other coil to produce a holding flux, then an opening current can be passed through one of the coils to produce a flux sufficient to open the valve, and when the valve is to be closed, a current can be passed through the one coil which is such as to close the valve. Three separate coils, Fig. 7 (not shown) may be provided for the holding, opening and closing fluxes. Instead, two coils 22A, 22B, Fig. 6, may be provided. Prior to opening of the valve, coil 22A is energized via a control transistor 25C and a resistor 3, the resistor limiting the current to a value which is insufficient to open the valve but would be sufficient to hold the valve open if it were already open. When the valve is to be opened, a control pulse is applied to a transistor 25A to increase the current temporarily to a value which effects opening of the valve. Thereafter, the valve is held open by the current supplied via the transistor 25C. When the valve is to be closed, a brief control pulse is applied to a transistor 25B to energize coil 22B which is wound in antiphase to the coil 22A, and at the same time a longer control pulse is applied to turn off the transistor 25C. The tendency of coil 22B to reverse the magnetic flux established by coil 22A assists the rapid collapse of the flux and hence rapid closing of the valve. In Fig. 5, coil 12A is used exclusively for the hold current, controlled by transistor 15E, while coil 12B receives both the opening pulse via transistors 15A, 15B and, in the opposite direction, the closing pulse via transistors 15C, 15D. In Fig. 8 (not shown), the circuit is rearranged so as to eliminate one of the opening transistors. Fig. 10 shows an injector valve having two coils 127A, 127B, one of which is the hold coil. After the return spring 130 has been adjusted by sliding an adjuster 124 longitudinally by means of a tool, the core 121 is caulked against the adjuster to hold it in place. Filter 122 is then inserted.

Abstract: 840,407. Photographic colour separation procedure. MIEHLE-GOSSDEXTER Inc. Feb. 25, 1958 [Feb. 26, 1957], No. 6037/58. Classes 97(1) and 98(2) Colour separation records corrected for the media, such as pigments having solid primary and secondary colours as well as black and white, to be used in printing a reproduction therefrom by factors having positive and negative signs based on the reflectance/absorbance characteristics of printed samples of such pigments and the paper on which they lie, are made optically by preparing a composite image from light images of the negative factor signs and interposing this as a mask in the optical system used for exposure of the positive factor signs. These positive and negative sign factors are determined by illumination of a chart of the pigments and recording reflection intensity readings by a meter included in a photocell pick-up circuitry fully explained in U.S.A. Specification 2,567,240 and referred to in Specification 828,501 (which latter is directed to the preparation of separation records by conversion of electrical signals as distinct from the alleged optical method), but in the present Specification illustrated only by quotation of numerical results following red, green and blue light exposure for white, green and black areas of the chart, colours selected because in the red separation negative it is desired-to.have the green and white colours of equal density and maximum with respect to the black density: and by a mathematical indication of procedure in the case of eight different chart colours. Apparatus for the optical operation, to be incorporated in a process camera, has a panel 10 in place of the customary lens board with eight optical assemblies 11 circularly arranged about the optical axis 12, each assembly comprising lens 13, colour filter 14, diaphragm aperture or control member 16, shutter 17 and reflecting mirror 18, whereby images of copy 19 illuminated by light source 23 may be superimposed in the focal plane 21 carrying panchromatic film 22. In use the diaphragms 16 are set in accordance with the factors referred to above, the shutters for those with negative sign factors opened those with positive sign factors closed, and exposure effected; after which the film 22 is processed, replaced and used as a mask for exposure on a further panchromatic film 24, this time with the negative sign diaphragms closed and the positive sign diaphragms opened, and such film 24 when processed constitutes a colour corrected separation record, for instance the red separation. The procedure is repeated with different diaphragm settings for other colour separations as required.

Abstract: 890,626. Cathode-ray storage tubes. ENGLISH ELECTRIC VALVE CO. Ltd. Dec. 6, 1960 [Feb. 22, 1960], No. 6132/60. Class 39(1) A signal storage cathode-ray tube utilizes a foraminated storage electrode exhibiting the "Malter" thin film field emission effect. In a direct viewing storage tube the storage electrode 3 consists of a nickel or stainless steel mesh coated on the side facing the collector electrode 4 and gun 5 with a thin insulating layer of magnesium oxide, or of caesium oxide on alumina, and on the side facing the fluorescent screen 2, with a layer of field emission inhibiting material such as gold. The charge image is laid down on the storage electrode in consequence of the secondary emission arising under bombardment by the beam and as a result of the positive charge acquired by the storage electrode, field emission due to the Malter effect commences, the emitted electrons passing to the collector electrode. Some electrons, however are drawn through the interstices of the storage electrode to land on the fluorescent screen. The electron beam is switched on and off in accordance with the signals to be stored and displayed. The storage image may be erased by reducing the potential of the collector electrode or by increasing the potential of the storage electrode. The spacing between the storage electrode and the collector electrode and between the storage electrode and the screen may be 0.2 inch in each case. The voltages may be as shown. The electron gun 5 and the deflecting means may be replaced by a photo-cathode to produce a composite stream or the fluorescent screen may be replaced by a signal plate, a large continuous current being obtained from the signal plate in response to a transient signal applied to the electron gun.
