Patent TR-22961-A (TR)
IPC: C04B35/65
Filed: 1988-01-06
Abstract: A method of producing shaped, self-supporting ceramic bodies includes preparing a mold by applying a gas-permeable, conformable material (20) to a shape-defining surface of a shaped parent metal (10). The gas-permeable material (20), when set or stable, provides a mold with a shaped surface which is defined by, and is therefore substantially congruent to, the shape-defining surface. Upon heating, the parent metal (10) melts and flows from the mold into a receptacle without disturbing the mold. Oxidation reaction product is then grown by oxidation of the molten parent metal with a vapor-phase oxidant to form an oxidation reaction product which grows into the mold cavity and is shaped by it. A ceramic body is recovered from the mold and has substantially the same shape as the pattern section (12,14,18) of the original shaped parent metal (10).

Inventor: LARSEN TIM
IPC: G09F7/18
Filed: 1983-01-28
Abstract: A highway sign, preferably a large directional sign or board, has a circular frame 6 to which the outer edges of a sign surface 2 are fastened, for example, by pop rivets, and possibly with support and assembly elements arranged between the frame 6, to which the sign surface 2 may also be attached, and suitable suspension elements, and furthermore the frame 6 and possibly the support and assembly elements have the same cross sectional shape, Figure 2, with a smooth closed front side 4, to which the sign surface 2 is attached. The cross section of the common base profile 8 is essentially rectangular with a closed rectangle 12, whose opposite long sides 14 have extensions 16 beyond a short side 18 of the rectangle 12, which extensions at a distance from the short side 18 have edge pieces 20 inwardly projecting toward each other, which form between themselves a lengthwise opening 22 toward the short side 18, since the edge pieces 20 form inner wedge-shaped recesses 24 with the extensions 16. Thus, the highway sign can be constructed from a minimum of system elements, in that the frame profile or base profile 8 can be used both as frame element 6 and supporting and/or assembly element. Furthermore, several base profiles 8 can be clamped together with locking nuts 26, 32, 34, which have the same cross-sectional shape as the open back side of the base profile 8, and simple fishplates 28 and bolts 30. <IMAGE>

Patent GB-793020-A (GB)
Title: Improvements in preparation of nitriles
Filed: 1956-01-04
Abstract: Nitriles are prepared from aliphatic acids and ammonia by a method comprising a first step of reacting one or more (C8-C20) aliphatic acids and ammonia in liquid phase at a temperature above the melting-point of said acids to form water and a mixture of amides, nitriles, unreacted acids and ammonium salts and removing the water of reaction substantially as rapidly as it is formed, and completing the conversion of said mixture to nitriles in a second step under vapour phase conditions in the presence of ammonia and a dehydration catalyst; said ammonia being introduced into the vapour phase step of the process in an amount greater than that required to saturate the water-of-reaction.  The ratio of ammonia entering the liquid phase is preferably between 1.2 and 2.0 mols. per mol. of acid, and the ammonia from the vapour phase step may be cycled through the liquid phase step.  The liquid phase step is preferably carried out in the presence of a dehydration catalyst and at a temperature of between 200 DEG  and 300 DEG  C., and the vapour phase step is preferably carried out at between 300 DEG  and 400 DEG  C.  The dehydration catalyst is preferably insoluble in the aliphatic acids, e.g. activated alumina, silica gel, titania gel and acid clays.  Other catalysts specified are phosphoric acid butyl stannoic acid, and zinc and copper salts of coconut oil fatty acids, soya bean fatty acids, stearic acid, palmitic acid, oleic acid and tallow acids.  Aliphatic acid reactants may be saturated or unsaturated and include caprylic, pelargonic, capric, undecylenic, lauric, tridecylic, myristic, pentadecylic, palmitic, margaric, stearic, nonadecylic, arachidic, behenic, linoleic, linolenic, oleic, therapinic, arachidonic, elaidic and fatty acids derived by hydrolysis from palm, coconut and soya bean oils.  The examples describe the preparation of coconut oil fatty acid nitriles using an apparatus adapted for continuous working.

Abstract: 950,410. Escapement mechanisms. CROUZET S.A.B.L. Jan. 3, 1963 [Jan. 27, 1962], No. 334/63. Heading F2X. A gear-wheel 2 is adapted to be driven intermittently by a mechanism comprising a swing- ing plate 5 which carries a motor reduction gear unit 6, having a pinion 4 meshing the gear 2, and a two-arm lever 13, pivotally mounted at 12 on a stationary plate 1, having a finger 14 adapted to engage the teeth of the gear 2 and having a boss 18 which is adapted to be engaged by a portion 19 of the swinging plate 5. The plate 5 is urged in a clockwise direction with respect to the stationary plate 1 by springs 9, the movement being limited by pins 8 engaging slots 7. A spring 16 urges the lever 13 in a direction to engage the finger 14 with the teeth of gear 2. Rotation of pinion 4 in the direction of the arrow F causes swinging of the plate 5, in the direction of the arrow f, until the portion 19 of the plate 5 engages the boss 18 thereby releasing the finger 14 from engagement with the teeth of gear 2 and allowing rotation of gear 2, the plate 5 returning to its original position under the influence of the springs 9 and allowing the finger 14 to engage another tooth. Alternatively, the release of the lever 13 may be effected by a cam driven by the motor.

Title: Lubricated rotary plug valve
Inventor: HULSLANDER WILLIAM LEO
IPC: F16K5/22
Filed: 1958-01-03
Abstract: 884,727. Valves. HOMESTEAD VALVE MANUFACTURING CO. Jan. 3, 1958, No. 362/58. Class 135. Synthetic lubricant at 20 is forced by a screw in the operating stem of a rotary plug valve 11 past check valves 22, 23 and radial passages into an annular metering groove at the top of the rotary surface of the plug and then via four vertical peripheral grooves 14, 15 to a lower annular surface groove. When all the grooves are filled lubricant flows from the passage 17 through metering passages to an annular chamber 28 between the plug and the valve cover 30. The chamber is restricted by a plastic ring 35 sealing on the cover and a cylindrcial extension 34 on the plug and also by the plastic dam 31 slidably sealing in grooves 32, 33 in the plug and cover respectively. The ring has bevelled edges so that, as shown, the ring seals over a larger area on the cover than on the plug and thus is maintained against the cover by lubricant pressure. As lubricant pressure increases in chamber 28 the plug is moved downwardly against a spring until a reduced portion on part 34 moves slightly below the ring so that lubricant escapes around the stem and gives visual indication that the chamber is full. The valve is then fully charged for automatic lubrication and the spring slowly forces the plug upwards and lubricant out of the chamber 28 into the passages. For non-automatic lubrication the ring 35 is reversed so that both ring and plug are forced downwards by the lubricant pressure in chamber 28, the escape of lubricant over the ring acting as a relief valve and around the stem being an indication that all the passages are full. U.S.A. Specification 2,965,123 is referred to.

Title: Article handling device
IPC: B65G47/14
Filed: 1949-01-06
Abstract: 662,146. Feeding articles in predetermined attitude. SYLVANIA ELECTRIC PRODUCTS, Inc. Jan. 6, 1949. [April 30, 1948] No. 430/49. Class 117. A feeding device for delivering cupshaped articles 50 the right way up into a dispensing shoot 30 comprises a tilted. reservoir having a rotatable rim 14 provided with article receiving chambers 15 each of which has a resilient cam-operated finger 18 arranged to allow release of " right-way-up " articles into the dispensing shoot 30 but to engage and hold reversed articles in the chambers 15 for subsequent release therefrom into a second shoot having side walls 62, 63, arranged to turn over the articles received thereby and discharge them into the reservoir. As shown the reservoir comprises a fixed circular plate 10 surrounded by a rotatable ring 12 to which the rim 14 is attached, the ring 12 being driven through gearing by a motor 90. The apertures 15 in the rim 14 open into chambers on the ring 12 bounded by side members 16 which are skewed to help retain the cups 50 during their travel to the upper part of their orbit. Each cup retaining spring finger 18 (Fig. 5), is pivotally mounted on a block 19 secured to the periphery of the ring 12, the finger 18 being normally spring-urged out of engagement with the cup 50 but moved theretowards by a cam 25, fixed at the top of the travel orbit, engaging the outer end of the finger 18. A resilient guide wall 26 mounted on the plate 10 ensures that the cups 50 approaching the top of the travel orbit are seated deeply in their chambers. The cups 50 which are concavity upwards (Fig. 5), will be retained in their chambers by the spring fingers 18 under the action of the cam 25, but those which are right way up (concavity downwards) will not be held by the fingers 18 and will slide under gravity into the dispensing shoot 30 which is supported to pass over the lower part of the reservoir. If the shoot 30 is full the released cups will slide to the right thereof (Fig. 1), back into the reservoir, their movement being retarded, to avoid damage, by padded resilient skewed baffles 40, 41, 42. As the rim 14 moves beyond the operative area of the cam 25 the spring fingers 18 are urged upwardly by their springs 22 to release the retained cups which are then guided into the cup reversing shoot by a guide wall 61. The side walls 62, 63, forming this shoot respectively decrease and increase in height in the direction of travel of the cups 50, the lower part of the wall 63 overlying the wall 62. The tilting of the reservoir can be varied by adjustment of a clamping screw 96 along a slotted link 94 by which the device is supported on its main base 92.

Abstract: 930,125. Lights for small arms. BIRMINGHAM SMALL ARMS CO. Ltd. April 3, 1962 [Jan. 5, 1961], No. 450/61. Class 119. A telescopic sight 1 supported on a channelshaped mount 2 by which it is secured to the small arm, is connected to the mount by two longitudinally spaced screwed pins 12, 18 disposed with their axes perpendicular to one another and to the sighting axis, each pin being adjustable so as to tilt the sight 1 with respect to the mount 2 about the axis of the other pin. The body of the sight 1 is provided with integral bosses 9; 10, the boss 9 being received between spaced wings 11 on the mount 2, and the pin 12 passing through apertures in the boss 9 and wings 11. A head 13 on the pin 12 turns in a clearance hole in one wing 11 and engages one side of the boss 9 so that tightening of a nut 14 moves the boss 9 and hence the sight 1 against the action of a spring 15 which prevents backlash. The pin 18 is moulded into the boss 10 and passes through an elongated hole 17 in an extension 16 of the web 3 of the mount 2, the web 3 being formed with a resilient tongue 20 engaging the underside of the sight 1. Tightening or loosening a nut 19 on the pin 18 thus raises or lowers the rear end of the sight 1. The nuts 14 19 may be calibrated. The mount 2 is secured to the small arm by the means described in Specification 930,124.
