Title: Method of and apparatus for making structural members
IPC: B28B23/00
Filed: 1964-11-05
Abstract: 1,090,841. Moulding hollow concrete beams &c. W. DICKINSON and W. J. M. HAINES. Feb. 4, 1966 [Nov. 5, 1964], No. 45130/64. Heading B5A. [Also in Division E1] Hollow concrete building elements are formed by a method comprising withdrawing a core from a mould once the concrete has partially set, the top of the elements being supported by a non-structural layer of wire-reinforced cardboard which seats on the cores and becomes part of the elements. The method comprises traversing over a bed of concrete between side shuttering (30) an electrically driven trolley 23 which supports four parallel, rigid cores 26 each of which is disposed below a reel 26 carrying the cardboard. As the trolley traverses in the direction of the arrow at 1“ feet/minute the cardboard unwinds on to the cores and wet cement discharges thereonto from the shoot 28. By the time (after 9 minutes) the cores have withdrawn from the element the cement has partially set the cardboard supporting the top (15) of the element. The bed (25) of the mould is heated by steam pipes (29), and the bottom layer of concrete may be laid either by initially traversing the trolley without the cores, or by having a shoot projecting in front of the trolley.

Abstract: 1,192,800. Oil blast switches. ALLM€NNA SVENSKA ELEKTRISKA A.B. 4 Oct., 1967 [5 Oct., 1966], No. 45188/67. Heading H1N. An oil circuit-breaker comprises a chamber 2 immersed in oil in a vessel 1. The chamber 2 is completely closed at its upper end and contains gas 9. A partition 5 separates the chamber into upper and lower compartments 6, 7, the partition supporting a fixed contact 8. The movable contact 4 passes through an opening 3 in the lower insulating wall 11 of the chamber closing the opening. A wall 12 in the vessel 1 defines with the wall 11 an annular channel 13 filled with oil; the inner end of the channel 13 is closed by the contact 4. During interruption, the arc first generates pressure in chamber 2 compressing the gas 9 which causes a flow of oil through opening 3 into channel 13 as soon as the contact 4 opens them. Oil pockets 15 enhance the extinguishing power at low currents.

Abstract: 1352369 Gas turbine engine combustion equipment GENERAL ELECTRIC CO 29 Sept 1971 [4 Jan 1971] 45300/71 Headings F4T  TM3 TP3D and TL1 The invention relates to gas turbine engine combustion equipment and to means for supplying fuel/ air mixture to the combustion zone. The combustion equipment is of the fully annular type and comprises outer and inner air casing walls 34, 36 and outer and inner flame tube walls 38, 40. An annular dome member 48 is disposed at the upstream end of the flame tube and an annular air and fuel mixing assembly is mounted therein, the assembly comprising an upstream wall 54 and outer and inner walls 56, 58 which define an annular chamber 52 which converges to define an annular inlet opening 60 into the combustion zone 46. A series of air inlets 64 comprising curved walls 69, 70 extend through the wall 54, a fuel injector 72 projecting into each inlet duct whereby a fuel and air mixture is turned from an axial direction into a nearly tangential direction as it enters the chamber 52. A series of guide vanes 62 are disposed within the chamber 52 whereby the fuel/air mixture is discharged into the combustion zone with axial and circumferential components. Series of swirl vanes 78 are disposed in annular inlets outwardly and inwardly of the annular inlet 60 whereby air flows into the combustion zone in counterflow to the flow of a fuel and air mixture entering through the annular inlet 60.

Abstract: 1,097,131. Gas blast switches. ENGLISH ELECTRIC CO. Ltd. Nov. 9, 1964 [Nov. 16, 1963], No. 45347/63. Heading H2B. The main interrupter and resistance switch contacts 10, 35 of a gas-blast circuit breaker are coupled to pistons 13, 36 respectively, movable in cylinders 14, 30 by compressed gas supplied through valves so that the main switch is closed before the resistor switch, the contacts being in gas-filled enclosures which are sealed both when the contacts are open and when they are closed. The breaker is opened by unlatching a rod 73 which, under a spring 74, moves to change-over a valve 82. This supplies compressed gas through a line 87 to open a blast valve 27, venting the interiors 23, 55 of the nozzle-shaped contacts 10, 35 and also cylinder 14 so that the gas in line 86 moves piston 13 to open the main contacts 9, 10. In this movement a contact biasing toggle 16, 19 is moved overcentre and pulls a rod 80 to reset valve 82 and also operates a valve 70 to actuate a shuttle valve 42 to vent the cylinder 30 of the resistor switch. Since a line 56 is also vented through the blast valve the piston 60 of a delay valve 57 moves slowly downwards eventually connecting to other side of piston 36 to the gas supply to open the resistor switch 34, 35. To reclose, the rod 73 is pulled down, changing over a valve 81 to vent lines 64, 86 to close the main contacts 9, 10 and, after pressure in line 56 has moved the piston 60, to vent line 69 to close the resistor switch.

Title: Speed control systems
IPC: H02P5/50
Filed: 1974-10-23
Abstract: 1484926 Automatic control of speed OWENS-ILLINOIS Inc 23 Oct 1974 [24 Oct 1973] 45811/74 Heading G3R In a speed control system for a plurality of electric motors operating in parallel, each motor is automatically regulated to a predetermined speed which is changed if the speed of one of the motors falls below a minimum value. In the embodiment, each motor 10 is controlled by a system as shown in which pulses from a motor driven encoder 14, having a frequency dependent upon the motor speed, are counted at 58 for a given time period determined by time base generator 56. The count, which is indicative of motor speed, is normally compared in a binary comparator 74 with a predetermined desired value 22. Any difference is used to vary the position of a servo potentiometer 40 to maintain the motor at the desired speed. However if the speed of one of the motors falls below a minimum value, an emergency logic system 62, that is common to all motor control systems, causes binary switch 76 to change state. This changes the reference to comparator 74 from the desired speed 22 to an emergency speed 23, which may be above or below the desired speed 22. The motor is thus regulated to run at the emergency speed. Details of the time base generator 56, count and hold circuit 58, comparator 74 and emergency logic 62 are given in Figs. 3 to 6 (not shown). The system may be used to control motors in glass container inspection machines that run in parallel from a single container making machine, and, if one of the inspection machines stalls or is stopped for repair, the other machines are speeded up to avoid build up of containers.

Title: Vibration isolation systems

IPC: F16F7/10
Filed: 1968-10-03
Abstract: 1292021 Vibration isolating systems KINS DEVELOPMENTS Ltd 2 Jan 1970 [3 Oct 1968] 46998/68 Heading F2S Two members, such as a body 1 and a foundation supporting it are isolated against relative vibration by means of a pair of interconnected pneumatic isolators I 1 , I 2  acting in series and resilient means such as springs 3. The isolating system also includes an inertia mass 2. The arrangement is such that for low frequency vibrations isolation is effected by the pneumatic isolators and for high frequency vibrations by the springs. In Fig. 4, a " capillary " tube 4 interconnects the isolators, which are identical piston-cylinder devices. The tube 4 may have a diameter of one inch and the cylinders diameters of one foot. In the static case, or for low frequency movements of the body 1, I 1  and I 2  exert equal and opposite forces on the inertia mass 2 so that the latter is effectively supported by the springs alone. Hence low frequency vibrations of the body 1 are absorbed by the interconnected isolators. At high frequencies, the " capillary " tube is effectively blocked so that the only damping agency is the mass-spring system 2, 3. A typical characteristic is shown in Fig. 5 in which # = 0 corresponds to zero damping coefficient (i.e. unrestricted flow of fluid in the capillary tube) and # = # to infinite damping (totally blocked capillary). The damping characteristic must at all times lie within these limits, so the actual characteristic of a particular apparatus will lie within the shaded area defined by the theoretical limits on #. The Specification contains a theoretical discussion of the performance of the proposed system and its advantages over previously known isolating systems.
