IPC: C22B1/20
Filed: 1975-07-16
Abstract: 1475026 Controlling ore sintering CENTRE DE RECHERCHES METALLURGIQUESCENTRUM VOOR RESEARCH IN DE METALLURGIE 16 July 1975 [19 July 1974] 29805/75 Heading ClA [Also in Division G3] A method controlling sintering of ores comprises determining the temperature distribution along a transverse zone of the upper surface of the sintering bed at the outlet of the mixture ignition hood by means of a radiation detector and controlling the ignition conditions accordingly. The radiation detector is preferably a pyrometer for IR covering 400-1,000‹ C. Scanning of the temperature profile may be performed by means of oscillating or rotating mirrors or by oscillating the detector about an axis. In the example, the signal from the detector is amplified, de-modulated and applied to an oscilloscope for displaying in real time, a sampling unit and a small computer. The computer or sampling unit may control various parameters, such as flow rate of fuel gas, in order to control the ignition of the mixture.

Abstract: 898,769. Copying telegraphy. TIMES FACSIMILE CORPORATION. Aug. 30, 1960 [Sept. 14, 1959], No. 29869/60. Class 40(3). In a facsimile receiver the marking device comprises a recording member supported for substantially unrestrained movement towards the recording blank, the recording member exerting a variable pressure on the blank under the control of an electromagnet. In a first embodiment, Fig. 1, the recording blank 10 passes between a rotating drum 17 and the recording member 14. The drum 17 is of ferromagnetic material and has a helix 19 formed thereon. Member 13 comprises a bar running the length of the drum and is supported on one of the legs 20 of the core 21 of an elongated electromagnet 22 which also runs the length of the drum. The other leg 24 of the core is positioned close to the drum, and when facsimile signals are fed to the electromagnet member 14 moves towards the drum, thus exerting a pressure upon the intervening recording blank and causing a mark to be made thereon. The amount of movement between the no-marking and heavy-marking positions of member 14 is very small. In modifications of this embodiment the marking member takes the form of a rod or is somewhat flexible, Figs. 4, 8, 9 and 10 (none shown). In further modifications the drum and helix are replaced by an anvil mounted on an endless moving belt, Fig. 6 (not shown). Various methods of supporting the recording member for unrestrained movement are described, and modifications to the drum are described with reference to Figs. 11, 12 and 15 (none shown). Several copies may be made simultaneously. Specifications 720,036 and 721,776 are referred to.

Abstract: 947,597. Cooling I.C. engines. KLOCKNERHUMBOLDT-DEUTZ A.G. Sept. 1, 1960 [Sept. 22, 1959], No. 30245/60. Heading FIB. In a cooling system for an I.C. engine thermostatic means responsive to the exit cooling air temperature activates control means to decrease the cooling air supply as the engine temperature increases through a first range immediately after starting and then actuates the control means to increase the supply of cooling air through a second temperature range as the temperature of the exit cooling air increases beyond a certain value. With increase of temperature, valve 1 is moved leftwards by a rod 3 connected to a thermostat in the exit cooling air stream. When the engine is started liquid is supplied from an auxiliary supply duct 5 through groove 7 and outlet duct 6 to an hydraulic slip coupling driving the blower, the speed of the blower being reduced, due to the restricted flow passages of grooves 8 and 9, as the air temperature increases, until edge 11 coincides with edge 12 when the blower is stopped. As the air temperature further increases the main supply duct 4 supplies duct 6 through groove 10, the speed of the blower rising in correspondence with the rise of air temperature. In a modification groove 9 is omitted and a small rate of cooling air is supplied by an enginedriven fan.

Title: Improvements in or relating to strong, homogenous, coherent coatings and self-sustaining films and method of forming same
IPC: B05D7/26
Filed: 1946-10-10
Abstract: Wood, glass, metals, rubber, plastics, resin or stone is coated with a vinyl resin by applying a coating of an aqueous dispersion of the resin, drying the layer at the "incipient softening temperature" to form a porous layer and heating the layer to its "softening temperature" to eliminate voids.  By "incipient softening temperature" is meant that temperature at which the discrete spherical particles of vinyl resin in the latex begin to fuse together on drying without complete elimination of the voids between the particles.  By "softening temperature" is meant the temperature at which substantial plastic flow occurs and the particles of resin fuse to a homogeneous mass.  The aqueous dispersion may contain a plasticizer, e.g. tricresyl phosphate, dibutyl phthalate, dioctyl phthalate, undecyl tetrahydronaphthyl ketone or cyclohexyl o-benzoyl benzoate.  Vinyl resins specified are polymers of vinyl chloride, vinyl bromide, vinylidene chloride, vinyl acetate, vinyl butyrate, styrene, mixtures thereof or copolymers of two or more of these monomers with each other or with methyl acrylate, methyl methacrylate, methyl ethylacrylate and ethyl acrylate.  The heating may be effected by a current of a hot gas or by infra-red lamps.  The aqueous dispersion may include pigments, fillers, reinforcing agents, dyes or stabilizers.ALSO:Films of vinyl resins are formed by coating a surface such as a metal belt or drum with a layer of an aqueous dispersion of the resin, drying the layer at the "incipient softening temperature" to form a porous layer and heating the layer to its "softening temperature" to eliminate voids and removing the layer from the surface.  By "incipient softening temperature" is meant that temperature at which the discrete spherical particles of vinyl resin in the latex begin to fuse together on drying without complete elimination of the voids between particles.  By "softening temperature" is meant the temperature at which substantial plastic flow occurs and the particles of resin fuse to a homogeneous mass.

Title: Disconnect clutch assembly for winch drum
IPC: B66D1/24
Filed: 1975-07-18
Abstract: 1508004 Winch drives CATERPILLAR TRACTOR CO 18 July 1975 [10 Oct 1974] 30301/75 Heading B8B [Also in Division F2] A winch drum 13 is either power driven for winding, or free wheeled for paying out cable, under the control of a disconnect clutch 40 at the output of a main drive shaft 26, the clutch 40 being associated with a brake 41 operable upon disconnection of the clutch 40 to produce resistance to pay out rotation of the drum 13. The disconnect clutch 40 comprises a jaw gear 42 rotatable on the shaft 26, and a jaw gear 47 splined for rotation with the shaft 26 and axially movable along the shaft for jaw teeth engagement and disengagement with the gear 42. The jaw gear 47 is coupled by pins 59, 61 to a piston 49 movable axially in a chamber 52 in the shaft 26, the gear 47 normally engaging the jaw gear 42 since the piston 49 is biased to the right by spring washers 63. Upon supplying hydraulic fluid to the chamber 52, the jaw gear 47 is disengaged with movement of the piston 49 to the left and the fluid pressure also forces detent pins 81, 82, seated in a diametral passage in the shaft 26, radially outwardly to frictionally engage an internal groove in the gear 42 whereby limited resistance to rotation is generated in the drum free wheel gearing. The detent pins normally engage the groove 87 lightly under the pressure of a spring 86, this tending to keep the jaw gear 42 in a rightward position but permitting movement to the left during teeth engagement with the jaw gear 42. The parting of the jaw gear teeth is facilitated by the gear 42 being secured in the rightward position by the operating brake pins 81, 82. The power transmission between a power shaft and the main drive-shaft 26 comprises a normally disengaged disc clutch between the power shaft and an input shaft 19, the latter driving the shaft 26 selectively in either direction by hydraulically relaxing either one of two normally engaged disc clutches 27, 33. The input shaft 19 inputs to the two clutches 27, 33 through bevel gearing 21, 22, 23 which locks if both clutches are engaged.

Title: Electric wave filter systems

Abstract: 493,982. Multiplex transmission. LORENZ AKT.-GES., C. Nov. 5, 1937, No. 30382. Convention date, Nov. 6, 1936. [Class 40 (iv)] [Also in Group XL] In a separator for filtering the carrier frequencies assigned to three or more transmitters or receivers S1, S2, S3, the cut-off frequencies determined by the attenuation characteristics of a low-pass filter F1, a highpass filter F3, and one or more band-pass filters such as F2, instead of coinciding with the limits of the appropriate side-bands, coincide with the carrier frequencies belonging to adjacent side-bands. Thus the attenuation characteristic of each filter has a wide pass band which overlaps the pass bands of adjacent filters, but undesired frequencies are excluded by the high value of the image impedances, which are arranged to be infinite at the cut-off frequencies. Correctors K1, K3 are added when necessary to ensure the latter result, and the impedances of the filters are matched to the apparatus S1, S2, S3 by networks N1, N2, N3. The arrangement has the advantage that the attenuation in the working pass range of each filter is lower than it would be if the pass bands determined by the attenuation constants were narrowed to coincide with the signal side-bands.

Abstract: 1346254 Photographic flash apparatus POLAROID CORP 29 June 1971 [29 June 1970] 30435/71 Heading G2A In a photographic camera having a shutter 52; a carriage assembly 232-248 for detachably receiving a multi-lamp percussive flash unit; a probe 40 for firing a lamp of an inserted unit; and an advancing arm 48 for rotating an inserted cube, the advancing arm is movable from a rest position Fig. 1 (not shown) to a terminal position in engagement with the carriage assembly Fig.6 (not shown), in response to depression of shutter release lever 76, this movement of the advancing arm 48 operating the probe 40, and subsequent movement of the arm 48 back to its rest position advancing the flash unit. Sequence of operations Depression of the lever 76 rotates loading arm 50 anti-clockwise (as seen) and also the advancing arm 48, by virtue of a pin 70 and slot 200 connection, thereby causing an engaging tab 204 Fig.8 to move to the position 204', with its returning edge engaging an indexing pin 242. The loading arm 50 also rotates a shutter actuator assembly 54 thereby tensioning a spring 144. An impulse actuator 46 remains stationary during this rotation by virtue of a pin 172 sliding on a cam 198 of the advancing arm 48, thereby tensioning a spring 174. As the advancing arm 48 reaches its terminal position at the full depression of the lever 76, the contact between the pin 172 and cam 198 is released allowing the actuator 46 to rotate rapidly under spring action and raise the probe 40 to fire a flash-lamp. The anti-clockwise rotation of the actuator 46 occurs simultaneously with clockwise rotation of the actuator assembly 54, which allows the shutter blade 52 to rotate clockwise and start the exposure. When fully open, a stud 124 of the actuator assembly 54 engages a cavity 168 in the impulse actuator 46, thereby rotating the latter clockwise to withdraw the probe 40 back into the camera housing. The spring 144 now causes the shutter blade 52 to terminate the exposure. When the lever 76 is released to permit the loading arm 50 to be returned to its initial position, the advance arm 48 reverses its motion and the tab 204 cams against the pin 242 causing anti-clockwise rotation of the carriage assembly 232-248. A detent element 278 rides out of slot 270 until it re-engages slot 272 at the correct orientation. With each such rotation, the inner carriage member 248 moves so that a tab (266) Fig. 12 (not shown) thereof approaches an end position at which the loading arm 50 is prevented from returning to its initial position. Removal of the used flash unit clears the tab (266) from the loading arm path.

Abstract: The process of the parent Specification, which consists in mercurizing ketones of the formula R.CO.R1 in which R is a substituted or unsubstituted aromatic or mixed aliphatic-aromatic radicle and R1 an aliphatic or mixed aliphatic-aromatic radicle, is extended to the mercurizing of the same compounds containing also within the molecule arsenic, antimony or iodine: the mercurizing is effected by heating either with mercurizing salts or by means of mercuric oxide in an alkaline solution.  The products have therapeutical value.  In examples p-acetophenone arsinic acid (see Specification 220,668) or antimonic acid dissolved in caustic soda solution is boiled with mercuric oxide.  The Specification as open to inspection under Sect. 91 (3) (a) refers generally to the mercurizing of aliphatic-cyclic organic compounds, containing carbonyl groups not forming part of a ring, and containing also in the molecule "one or more chemico-therapeutical agents or groups of inorganic or organic nature" such as "naphthol sulphonic acids, the CH2NH2 group or the NHCH3 group."  Examples are also given in which p-acetophenone-arsinic acid and "p-acetophenone-salicyclic acid" are heated with mercuric acetate.  This subject-matter does not appear in the Specification as accepted.  p-Acetophenoneantimonic acid is obtained by treating diazotized p-aminoacetophenone with an antimonite.
