Title: Improved Apparatus for Automatically Adjusting Railway Brake Apparatus and the like to Compensate for Wear.
Inventor: LUARD EDWARD SYDNEY
IPC: B61H15/00
Filed: 1916-12-04
Abstract: 110,644. Luard, E. S., and Rawlings, V. P. Dec. 4, 1916. Compensating for wear.-An arrangement for automatically adjusting railway or like brake apparatus to compensate for wear comprises a rack 6, Fig. 1, adapted to operate the brake-rod 5 and having relatively large teeth 7 in engagement with the brake cylinder levers 3, 3a, a second rack 12 having relatively small teeth 13 and a pin-and-slot or similar connexion with the rack 6 so as to permit relative movement of the racks, and a fixed or movable take-up tooth or teeth 22 in engagement with the rack 12. In normal operation, when no wear has taken place, the levers 3, 3a actuate the rack 6 and brake-rod 5, and the pin 8 moves to the end of the slot 9 without displacing the rack 12 and rod 11; when a certain amount of wear has occurred, the pin 8 moves the rack 12 so as to cause one tooth 13 to be taken up by the tooth 22 which, in the construction shown in Fig. 1, is a fixed tooth. On the return movement of the levers 3, 3<a>, the racks 6 and brake-rod 5 are not permitted a full reverse movement, and the brake blocks are maintained at their normal distance from the wheels. As the wear continues and more teeth 13 are taken up, the pin 16 on the lever 3a gradually rides up a tooth 7 in the rack 6 until, when a predetermined amount of wear has taken place, the pin 16 slips into the next tooth 7 and the movement of brake cylinder piston is restored to its initial amount. A spring 23 maintains the rack 13 and tooth 22 in engagement. In a modification, shown in Fig. 3, in which two sets of levers 3 are actuated by the piston, one brake-rod 5 with a large-toothed rack 6 has a pin-and-slot connexion with the rod 11, and the other brake-rod carries a take-up tooth 22 which engages with the small teeth 13 of the rack 12. The spring 23 is carried by the brake-rod and bears upon the rack 12. In a further modification, the movable tooth 22 is replaced by a movable rack having small teeth in engagement with the teeth 13, both racks moving in a housing and being pressed into engagement by a spring mounted on the housing. Specification 18795/10 is referred to.

Title: Improvements in or relating to thermoelectric generators
IPC: H01L35/00
Filed: 1966-04-21
Abstract: 1,091,729. Thermoelectric generators. GENERAL DYNAMICS CORPORATION. April 21, 1966 [April 27. 1965], No. 17453/66. Heading H1K. A thermoelectric generator comprises a housing 10 containing an elongated thermopile 16 consisting of a plurality of elongated thermoelement pairs formed of P-type and N-type material, respectively, the hot end of the thermopile being thermally connected to a source of heat such as a radioactive isotope 24 and the cold end being mounted in a thermal capacitor 26. Each thermoelement pair comprises two thin wires (17, 18) made of dissimilar materials such as Chromel-P, Constantan, Cupron Special or the material sold under the Trade Mark " Tophel Special," and thermobundles 56 are formed by grouping a plurality of series-connected pairs and bonding them together with insulating material such as a silicon elastomer. A plurality of thermobundles are connected in parallel to form a set (58) and a plurality of sets are connected in series to give the generator output which is obtained via tapoff leads 28. Various output voltages may be obtained by connecting extra tap-off leads between the sets. The housing 10 is made of aluminium, and contains thermally insulating material 30 of low density and high rigidity which assists in supporting the thermopile. The generator is designed to minimize the effect of changes in the ambient temperature on output voltage, and therefore the thermal time constants of the structures adjacent to and including the hot and cold junctions must be equal so that the temperature difference between the hot and cold ends of the thermopile will remain constant. The thermal time constant of a structure is equal to the product of its thermal resistance and its thermal capacitance, and in the generator the temperature difference between the hot and cold junctions is maintained by the high thermal resistance of the structures adjacent to the hot junctions and the fuel 24 and the low thermal resistance of the structures adjacent to the cold junctions. Consequently. the thermal capacitance at the cold junctions must be proportionately higher than the thermal capacitance at the hot junctions, and this is achieved by providing a massive thermal capacitor 26 made of stainless steel and thermally connected to the housing 10 by studs 40. Suitable material for the fuel 24 is plutonium 238. A jig is described (Fig. 5, not shown) for use in the manufacture of the thermobundles.

Abstract: 1,003,158. Funnel kilns. L. S. POURSIN. May 7, 1962 [Oct. 17, 1961], No. 17544/62. Heading F4B. Agglomerated materials containing combustible matter, such as coal shale bricks, are fired at least partly by the heat of combustion of the incorporated fuel, the bricks being preheated to initiate combustion of the fuel, all the incorporated fuel being at least partly burst without the temperature exceeding that at which the bricks sinter by injecting air or steam on to the bricks to produce producer gas or water gas which is burnt in the presence of the bricks, and the fired bricks are cooled. The bricks, stacked on trucks 15, move through the preheating zone in countercurrent to the gases delivered from flue 30. In the firing zone, the bricks move in the same direction as the gases, which are delivered from flues 31, 32, 33 to a waste heat boiler or other heat recovery plant. In the cooling zone, air from fan 42 flows in countercurrent to the bricks and is withdrawn through passages 43, 44 to be fed to air inlets in the reaction or preheating zones. The zones are separated by steam curtains, and the temperature distribution within the firing zone is controlled by regulating the air supply and steam supply to balance the exothermic producer gas reaction and the endothermic water gas reaction.

Title: Improvements in textile oils
Filed: 1940-12-18
Abstract: 547,667. Textile oils. GOODINGS, A. C.; MARSHALL, H. B., and LEMON, H. W. Dec. 18, 1940, No. 17855. Convention date, Dec. 21, 1939. [Class 91] [Also in Group IV] Addition agents for mineral base oils to form a composition for use as a textile oil, comprise diesters of polyhydric alcohols having at least three hydroxyl groups in which one hydroxyl group is esterified with a long chain fatty acid of at least ten carbon atoms, and a second hydroxyl group is esterified with a short chain aliphatic acid of less than six carbon atoms. The polyhydric alcohol is preferably glycerol. The long chain fatty acid is preferably saturated but in, any case should not contain more than two double bonds. The short chain aliphatic acid preferably does not contain more than four carbon atoms. Suitable long chain fatty acids are oleic acid and the acids of naturally occuring non-drying oils including the vegetable fatty oils such as coconut, the animal oils such as neatsfoot and lard oils as well as mixtures of such acids particularly the mixed acids obtained on hydrolysis of such naturally occurring oils. Of the short chain aliphatic acids, acetic is the preferred acid. The preferred polyhydric acohol is glycerol but erythritol and mannitol may also be used. The addition agents are added to a base oil comprising refined mineral oils preferably in amounts of 5-7 per cent. by volume of the base oil, but amounts up to 20 per cent. may be used. The mineral oils used should have a gravity A.P.I. of 23-36, a viscosity (Saybolt Universal at 100F.) of 50-250 and a pour point of 0F.-50F. Oils which have been subjected to a fuming acid treatment are particularly suitable. In addition to the agents above referred to there may also be added to the mineral oil base liquid diglycerides of long. chain fatty acids of at least 12 carbon atoms, such as neatsfoot-diglyceride. Examples of addition agents according to the invention are coconut-acetic diester of glycerol, neatsfoot-acetic diester of glycerol, and neatsfoot-lactic diester of glycerol. The preparation of the coconut-acetic diester of glycerol is carried out by first forming coconut monoglyceride using an excess of glycerol, the excess of glycerol is removed by extraction with water and the coconut monoglyceride is then acetylated with acetic anhydride. Alternatively the coconut monoglyceride may be directly esterified without removing the excess of glycerine, in which case some acetic diglyceride is formed which has to be removed by extraction with water.
