Title: Improvements in Composition for use as a Substitute for Wood in Building Construction and Method of Producing the same.
Inventor: WHEELER WILLIAM HENRY
IPC: C04B28/26
Filed: 1916-10-05
Abstract: 111,686. Wheeler, W. H. Oct. 5, 1916. Fibrous plastic compositions.-A wood substi tute is moulded from a composition consisting of a fibrous filler, such as asbestos or saw dust and a composite binder, previously prepared, consisting of a mixture of a soluble silicate and Portland slag, natural or other cement, containing a substantial proportion of calcium oxide. The weight of the binder is preferably greater than that of the filler, and the percentage of water in which the soluble silicate is dissolved should preferably be that required to set and harden the cement. The moulded mass is then left at the ordinary temperature or at a temperature up to 100‹ F., and may then be subjected to a gradually rising temperature to assist the separation of the water from the soluble silicate and its combination with the cement. The moulded article is finally soaked in water to dissolve out free alkali which is associated with the alkali silicate. As an example, 30 parts by weight of fibre are mixed with 10-40 parts of cement and 60-30 parts of soluble silicate. Specification 1390/12 is referred to.

Title: Improvements in regenerating hydroforming catalysts
IPC: B01J23/96
Filed: 1956-05-08
Abstract: In a process for hydroforming naphtha in the presence of platinum catalysts, the catalyst is regenerated in the reactor by treating with an oxygen-containing gas and a halogen or volatile halide which (calculated as Hcl) is present in <PICT:0798239/III/1> a proportion of 0.2 to 2 mols. per mol. of water contained in the regenerating gas.  HCl, HF, CCl4 or chlorine are specified. The halogen is absorbed on the catalyst and replaces that removed by the water vapours formed in the main reaction and at the regeneration stage. The hydroforming plant shown consists of a lead reactor chamber 5 with associated preheater 3, a second stage reactor 9 and pre-heater 7, and a tail reactor 13 and pre-heater 11, connected to a naphtha supply pipe 1, recycled hydrogen supply pipe 2, and product recovery system (cooler 15, and separator 17).  To regenerate the used catalyst, the supply of naphtha and hydrogen is cut off, and a purging gas (nitrogen or flue gas) is admitted through a pipe 24 to remove vapours from the reactors.  Air is then admitted from a line 22 together with flue gas, and simultaneously HCl through a line 23. The oxygen content of the gaseous mixture is about 1.2 mols. per cent, and the HCl about 0.3 to 0.7 mols. per mol. of water.  The carbonaceous deposits are burned off.  The furnace heaters 3, 7 and 11 may be by-passed in this operation.  The gaseous products may be vented or passed through the separator 17 to remove water, and the gas re-cycled through a line 25.  At the final burning off stage the oxygen content of the regenerator gas is increased and may be effected under a pressure of 200 to 400 p.s.i.g., for up to 24 hours at 900/1000  DEG  F. which is stated to reduce the particle size to about 50   or less.  The catalysts are then treated with a purging gas, preferably nitrogen or dry flue gas, to remove any carbon oxide gases present.

Filed: 1974-04-02
Abstract: 1462386 Air conditioning apparatus O KRETZSCHMAR 2 April 1974 [3 April 1973] 14617/74 Heading F4V  Air conditioning apparatus comprises a casing 2 containing a blower and an arrangement 3 for regulating the temperature and an arrangement 4 for regulating the moisture of air emitted from the outlet 6. In Fig. 1, automatic temperature regulation is represented by the device 12 moving a part within the device 13 and automatic humidity regulation is represented by the device 12 moving a part within the device 14. A further control means represented by the shafts 8 and 9 can superimpose on the automatic regulation above, a temperature and humidity variation in a synchronous or asynchronous manner according to a programme that can be selected on the rotary cam control devices 17 and 18. The temperature regulating arrangement may include a heating resistance 56 on a rotatable support 54 which is adjustable with respect to a sliding arm 57 so that the resistance between the connections 58 and 59 varies. The rotatable support 54 is connected by a rod system 55 with the device 12 and the sliding arm 57 is operated by the shaft 8, thus providing two inputs to the temperature regulating arrangement. The humidity regulator may comprise a valve 60 for control of water supply from a pipe 61 to a pipe 62. The valve seat 63 is screwed into the thread 68 of the housing 60, so that rotary movement moves the seat in and out relative to the valve 67. The seat is rotated by a lever 69 connected by a rod 70 with the device 12. The valve body 67 is connected to the shaft 9 and by means of a threaded portion 64 and bushing tapped at 66, rotation of the shaft moves the valve body 67 in and out relative to the seat 63. The valve can thus respond to two inputs. The rotary cam control devices 17 and 18 may comprise a number of cams of different profile and may be arranged so that any one of the cams can be brought into use according to the superimposed programme desired. The cams are rotated by a motor 37 through variable speed pulleys 46 and 47. Cam followers (27), Fig. 2 (not shown), bear against the cam profiles and transmit movement via the tappet rods 22, 21 to the shafts 8 and 9.

Abstract: 595,451. Toothed gearing; friction-dutch es; variable-speed gearing. BORG-WARNER CORPORATION. Aug. 2, 1944, No. 14763. Convention date, July 14, 1943. [Classes 80(i) and 80(ii)] [Also in Group XXXIII] The transmission between the drive shaft and the sustaining rotor of a helicopter (see Group XXXIII) is contained in a housing 10, Figs. 1 and 2, and comprises an input shaft 11, 14 connected through a multiple friction clutch 15 a cam and roller type free wheel clutch 27 and reduction gearing 31, 32, 33, 36, 37 and 38 to an output shaft 12. The clutch 27 is interposed between members 18 and 25 freely rotatable on an intermediate shaft 24, member 18 carrying one set of plates of the clutch 15 and member 25 being fixed to the gear 31. Gears 32, 36 and 33, 37 are formed integrally and are mounted on countershafts 34 and 35 carried by the housing 10. The ring gear 38 is formed on the enlarged lower end 39 of the shaft 12. The clutch 15 is engaged by an annular piston 20 actuated by oil under pressure supplied from a gear pump 40 driven by the shaft 11. Lubricating oil for the gears and mechanism in the upper part of the housing is also supplied from the pump through chambers and passages and an orifice 55, the latter being restricted so that sufficient pressure is built up to engage the clutch. The circuit of the pump includes a relief valve 59 which is normally maintained closed against the action of a spring 60 by means of a valve stem 61 which rides on a surface 62 of a member 63 which is rotated to operate the pitch control mechanism of the rotor. If the blades are set to a pitch corresponding to zero lift, the valve stem drops into a recess 64 in the member 63 and allows the valve 59 to open, thus relieving pressure in the system and disengaging the clutch 15. In a modification, Fig. 3, in which two gear ratios are provided, an input shaft 108 carries a drum 109 having splines 110 driving a clutch 112, and splines 111 driving a clutch 113. Clutches 112, 113 are similar to the clutch 15 and are operated by oil under pressure through a valve 124 and collector ring 123. The driven member 114 of clutch 112 carries a gear 115, and the driven member 116 of clutch 113 a larger gear 117, these gears meshing with pairs of countershaft gears 118, 119 respectively, which are connected to a third pair of gears 120 meshing with a ring gear 121 connected to an output shaft 122. Gears 118, 119 and 120 may be formed integrally as cluster gears. According to which clutch is operated, the rotor will be driven at a low speed through the gear 115 or at a higher speed through the gear 117.
