Title: Improvements in and relating to processes for manufacturing insulated products in the form of powder
IPC: A61K31/375
Filed: 1938-03-25
Abstract: 514,047. Vitamins. WELLS, E. E., and ROWNTREE & CO., Ltd. March 25, 1938, No. 9267. [Class 2 (iii)] A process for producing a powder containing l-ascorbic acid (Vitamin C) in a form in which it is protected from external influences comprises dissolving particles of the vitamin in a solution of gelatine, gum or hard sugar, drying the solution and powdering the residue. Where gelatine is used, it may be rendered insoluble by exposing the powder to the vapour of formaldehyde. Vitamin C may also be protected from external influences by dissolving it in melted fat or wax, e.g. cocoa butter, preferably with addition of finely powdered sugar, and then cooling and solidifying the product and finally pulverizing it. The products may be added to beverages, or mixed with milk powder, salt, or mustard, or used as an ingredient of meat cubes.

Abstract: 1,063,359. Gas turbine ducted fan jet engines. GENERAL MOTORS CORPORATION. March 3, 1966 [March 31, 1965], No.9305/66. Heading F1J. The invention relates to a gas turbine ducted fan engine of the aft fan type, the engine being suitable for use as a vertical lift engine. The engine comprises a compressor 5, combustion equipment 6 and a turbine 7, Fig. 1 (not shown), the turbine 7 comprising inlet nozzle guide blades 22 and a rotor 9 on which are mounted blades 23, the rotor disc 9, being drivingly connected to the compressor by shaft 10. The turbine and compressor assembly is supported at its downstream end in a bearing 46 which is mounted in a support 47. The gases discharge from the turbine blades 23 into an annular duct 25 defined between an inner wall 31 and an intermediate wall 33, the gases being directed by interstage guide vanes 26 on to the blades 27 of a second stage turbine which drives a ducted fan, the gases finally discharging through the outlet duct 30. The ducted fan comprises fan blades 34 carried by the shroud ring 35 of the turbine blades 27, the fan blades being located in an annular duct defined by the intermediate wall 33 and an outer wall 38, air entering the duct through inlet 37 and being guided by blades 41 upstream of the fan blades 34 and by blades 42 downstream of the fan blades 34, the air finally discharging through outlet duct 43. The turbine blades 27 and fan blades 34 are carried by a rotor 29, the shaft portion 49 of which is supported in bearings 50, 51, the bearing 50 being carried by the support 47. Hollow radial struts 55 extend from the bearing support structure 47 across the turbine flow duct 25 and the fan duct 43 and are secured at their outer ends to ring members 57 which carry engine mounting bosses 58. The struts 55 have heat shields 75 disposed therearound in the region of the turbine flow duct, cooling air tapped from the engine compressor being caused to flow radially outwardly within the struts, through openings 82 into the space between the strut and its surrounding heat shield 75, thence through opening 83 into the turbine flow duct.

Abstract: 152,051. Lodge, Sir 0., Lodge, L., and Lodge Fume Deposit Co. April 14, 1919. Gases, electrically precipitating suspended particles from.-To obviate deposition of dust on the discharge electrodes of electrical dustseparating apparatus, deflectors are arranged in advance of these electrodes so as to divert the gases towards the parallel metal plates constituting the sides of the channels and between which the discharge electrodes are mounted; the deposition of the particles on these metal plates is thereby facilitated. Transverse ridges or projections may also be provided along the sides of the channels in order to prevent dust already deposited on the plates, from being carried along by the gases. The deflectors may consist of ridgeshaped members d, Fig. 1, and to form the ridges the edges of the plates a may be bent as shown and connected by intervening strips c; or the edges of the plates may be supported between pairs of transverse tubes. Or the plates a may be discontinuous, alternating with discharge electrodes e as shown in Fig. 4; in this case the edge of the plates are enclosed by open-jointed tubes g of triangular or other section, the tubes serving to shield the electrodes e and at the same time arresting the already deposited particles; or the deflectors may be formed by beading the edges of the plates. In all cases the plates &c. are supported so as to permit free expansive movement; thus the tubes g, Fig. 4, may be supported at their upper ends by bent metal strips i, Fig. 5, carried by an inverted trough-shaped member b, and at their lower ends by a transverse j, Fig. 7, to which they are secured by clips k. The discharge electrodes preferably consist of vertical tubes with a single row of transverse discharge points.

Abstract: 758,761. Spring suspensions; preventing lateral canting. SOC. ANON. A. CITROEN. April 2, 1954 [Dec. 21, 1953], No. 9701/54. Class 108 (2). Relates to a hydraulic anti-rocking device for a vehicle having a wheel suspension system comprising wheel supporting members which are elastically sprung with respect to the vehicle chassis frame by means of springs or by means of pneumatic cushioning devices. According to the invention, the wheel supporting members for each pair of wheels on opposite sides of the chassis frame act on the pistons of a pair of hydraulic cylinders provided on the chassis frame, the displacement of the pistons by the wheel supporting members being cushioned by the springs or pneumatic cushioning devices, and that by means of a rotary pump inserted in a connecting pipe between the cylinders, liquid is transferred from one cylinder to the other under the control of a distributer which is operated by a predetermined movement of the wheel supporting members, the arrangement being such that liquid is removed from the cylinder on the less loaded side and delivered to the cylinder on the heavier loaded side of the vehicle. In the arrangement shown, in which a pair of road wheels 1, 1 is controlled by hydro-pneumatic suspension devices 7 operatively connected to wheel-carrying arms 2, the devices 7 are interconnected, through piping 9 and a slide-valve or rotary valve distributer 14, with a continuously rotating gear pump 8. The arrangement is such that increased loading on one side of the vehicle is resisted by transfer of liquid by the pump 8 from the device 7 at the other side of the vehicle. As shown, the distributer 14, controlling the direction of liquid flow comprises a rod 13 operatively connected to both arms 2, for sliding movement in the valve housing. The rod 13 is formed with reduced diameter portions 18, 20, 21 which, in the position shown, prevents liquid flow between the devices 7, but which under conditions of unequal wheel loading connects the pump delivery 15 to the heavier loaded device and the pump supply 16 to the other device.

Abstract: 803,846. Supply systems for welding arcs. UNION CARBIDE CORPORATION. March 26, 1957 [April 4, 1956], No." 9902/57. Class 38 (4). [Also in Group XXII] In arc welding using a plurality of electrodes at least one of which is consumable and a source of welding power having a volt-ampere characteristic that is substantially flat or rising in the usable welding range the speed of the or each consumable electrode is changed from a starting to a welding speed when the last arc is struck. The source may be of transformer type having a saturable reactor type of control producing a volt-ampere characteristic as shown in Fig. 2 with a high no-load voltage A but which is substantially flat or rising in the usable welding range B to D. Three consumable electrodes 11, 12, 13, Fig. 3, are fed at the same speed by feed rollers mounted together and driven by a single motor M. Actuation of a control 32 connects the same source 21 of welding current to each electrode and the electrodes are fed forward at a pre-set slow or fast starting speed. When a detector 25 in each welding circuit has responded to the striking of the respective arcs the feed rate is altered to a pre-set welding speed. At the same time traversing of the electrodes may be started or the speed of traversing increased. Actuation of a stop means 33 brakes the feeding motor M and, after a delay determined by a circuit 34, disconnects the welding current. The electrodes may be fed at different speeds either by providing different-sized rollers or by driving the rollers by separate motors. In this case an arc detector is provided only in the welding circuit of the slowest fed electrode. In a modification a non-consumable and a consumable electrode are used together.
