Title: Improvements in and connected with Internal Combustion Engines.
Inventor: DAVIDSON JOHN
IPC: F02B25/00
Filed: 1918-05-10
Abstract: 126,156. Davidson, J. May 10, 1918. Valves.-In a two-stroke-cycle engine of the kind described in Specification 119,401, in which the co-axial working and pump pistons are connected by a tubular extension acting as a valve. a tubular rod q is carried within the tubular extension c and acts as a valve to control the scavenging-air. The pump piston c compresses air on its upper side and mixture on its lower side, a piston-valve f controlling the distribution. The air is compressed into a. storage pipe i, and the mixture into a storage pipe k. The air pipe i communicates by branches t with casings p into which the tubular rods q extend. When the working piston b uncovers the exhaust ports a<1>, the scavenging-air is admitted through the rod q by radial ports r therein registering with cylinder ports s. Further descent of the piston causes ports o in the tubular extension e to register with the ports s and with a passage n communicating with the mixture pipe k, thus admitting the mix. ture. Fig. 3 shows a double-acting engine having a gas-compressing cylinder c on one side of the working cylinder a and a scavenging-cylinder y on the other side. Piston valves f, u control the gas and air, or automatic valves may be provided for the air cylinder. Or the cylinder may compress air on one side and gas on the other.

Title: Process for the preparation of sheet metal suitable for forming by the application of pressure
IPC: B21D22/20
Filed: 1961-03-03
Abstract: <PICT:0967199/C6-C7/1> A process for the manufacture of sheet metal suitable for forming by the action of pressure is characterized in that the sheet metal is subjected to a short heat treatment which results in the reduction of the hardness, tensile strength and yield point of the material of the micro-surface of the metal, thus improving its capability for undergoing deformation, the heat treatment being such as not to influence substantially the properties of the underlying material.  The heat treatment of the micro-surface is carried out by high frequency inductive heating for a period of from 0.01-0.1 second.  To improve the properties of the metal further at the same time as the heat treatment there is effected a decarbonizing and/or denitrogenizing of the micro-surface in a reducing atmosphere. Before the heat treatment is carried out, the micro-surface of the sheet metal is so shaped that it has a large number of substantially uniformly distributed slender peaks as shown in profiles 5, 6 and 7 of Fig. 1. This is effected by rollers which have been treated with a blasting material consisting of small grains of sand or shot, said material having been projected on to the roller surface at high speed.

Title: Improvements relating to apparatus for moulding and vulcanising rubber soles directly on to the uppers of shoes
IPC: B29C35/00
Filed: 1952-03-27
Abstract: 705,539. Moulding rubber soles on to footwear. SUPERGA SOC. PER AZIONI. March 27, 1952 [June 4, 1951], No. 7933/52. Class 87 (2) Apparatus for moulding and vulcanizing rubber soles on to the uppers of shoes comprises a rotary platform 3, presses mounted on the platform in radial formation around its axis and each comprising a mobile last 14 on which an upper is mounted and a stationary (with respect to the last) mould 15 in which a sole is placed, and one or more stations whereat the presses are unloaded (by removing the shoe from the last) and re-loaded (by placing a fresh upper on the last and a fresh sole in the mould) in succession. The lasts are operated by fluid-pressure rams 16 and are of the construction described in Specification 705,538, Fluid pressure is distributed to the rams from an annular conduit 30 through valves 31, one for each press, and is supplied through a pipe 27 to a rotary chamber 28 co-axial with the platform and thence through a conduit 29. The movement of the presses is covered by a shield 39 except at the loading and unloading station, where the shield has an opening, and on the shield at the station are fixed two tripping members, one of which is shown at 38. When the table brings a press to the unloading station the first tripping member strikes an operating member 36 on the spindle of the appropriate valve 31 and causes it to admit pressure fluid to a conduit 32 with the result that the piston in the ram 16 rises and opens the press. The press is re-loaded and as the table continues its movement the member 36 is struck by the second tripping member 38 and moved to cause the valve 31 to admit pressure fluid to a conduit 33 and close the press. As the press goes round on the table vulcanization heat is supplied to the mould 15 by steam supplied by a pipe 19 to a distributer chamber 18 whence it passes through a conduit 17 to the mould from which the exhaust steam and condensate passes through a conduit 20 to a second chamber 21 and thence to a reservoir 22. The last 14 is heated by electricity supplied through a conductor 41 connected to a contact ring 42 with which brushes 43, connected to a source of current, are in contact. The platform 3 is driven by a motor 1'2 through gearing 10. 9, 6. 5. Necessary material is kept on shelves 44 fitted above the shield 39.

Abstract: 789,087. Frequency and phase discriminators. PHILIPS ELECTRICAL INDUSTRIES, Ltd. March 18, 1955 [March 23, 1954], No. 7963/55. Class 40 (5). A frequency discriminator comprises a series resonant circuit 27, 28 from across the inductance and capacitance of which rectifiers 33, 34 are fed to give a differential output from a lowpass filter 37, 38, and the series circuit forms part of a parallel resonant circuit 27-30 resonant at approximately the same frequency so as to present across the input capacitor 30 a high impedance, e.g. to a pentode valve. Preferably the series resonance frequency lies between the half power points of the resonance frequency characteristic of the parallel resonant circuit, and may be varied between these points by varying the capacitor 28. Wider variations of the discriminator frequency may be obtained by conjointly varying, e.g. by a motor, both the capacitors 30, 28. The parallel resonant circuit as a whole may form part of a band-pass filter. The input may alternatively be connected to a tapping on the inductances 29 or 27. The discriminator may function as a phase detector if a frequency equal to that at its input is injected from a generator 41 into one or both of the output circuits through a coupling 42, 43, 431. The frequency or phase discriminator output may stabilize an input oscillation, or, through a motor, tune the discriminator to the applied frequency.

Title: Improvements in or relating to fuel supply apparatus for internal-combustion engines
IPC: F02M69/00
Filed: 1951-04-12
Abstract: 688,436. Fuel injectors; regulating. CUMMINS ENGINE CO., Inc. April 12, 1951 [June 14, 1950], No. 8521/51. , Classes 7 (iii) and 7 (vi). A fuel supply apparatus comprises a fuel pump delivering under substantially constant pressure, or a pressure varying with engine speed only, to a delivery line from which the fuel is distributed to the individual engine cylinders, the injection period being inversely proportional to engine speed, and is characterized by the delivery line between the pump and point of fuel distribution containing two adjustable throttle valves so interconnected that one valve moves towards closing position as the other moves toward opening position. A supply gear pump 24, Figs. 1 and 2, delivers to a float chamber 26 forming a supply reservoir for a constant pressure gear pump 32 having a delivery line 36 containing needle valves 37, 41, 43 and leading to a rotary distributer 35 controlling the connection to injectors 86. The valve 37 is a manually adjustable throttle valve and the valves 41, 43, are urged open by springs 72 and actuated by levers 70, 71 on a yoke pivoted at 63 and connected to the collar 61 of a centrifugal governor 50. As engine speed increases, the valve 43 moves toward closing and the valve 41 toward opening so that the valve 43 cuts off the fuel at excessive speeds and the valve 41 reduces the fuel flow at low engine speeds to counteract the increase in fuel supply due to the increased period of injection. The distributer 35 comprises a rotary plate 75, Fig. 2 having a radial passage 84 which is in constant communication with the fuel delivery passage 44 and engages in succession the passages 85 leading to the injectors 86 which include cam-actuated plungers 90 normally closing the fuel delivery ports 87. When used with a distributer, each plunger 90 is raised to open the port 87 slightly before the corresponding passage 85 is opened by the distributer, which controls the injection period. In a modification, Fig. 8, the distributer 35 is omitted and the fuel supplied to a pipe 95 common to all the injecters 96, the plungers 98 of which control the injection period. Non-return valves 88, Fig. 1, in the injectors 86 prevent air from the cylinders entering the fuel supply pipes. The governor 50 is carried on an engine-driven shaft 52, Fig. 2, which drives the distributer shaft 77 and the common shaft 100 of the pumps 24, 32, through bevel gears. At idling speed a groove 92 in the valve 41 opens an idling by-pass 91 and idling fuel is supplied through a groove 93 to a point downstream of the valve 41. A shut-off valve 45 is provided.

Title: An instrument for indicating ships courses
IPC: G01C21/20
Filed: 1925-03-31
Abstract: 253,263. Stuart, J. F. March 31, 1925. Plane-trigonometry calculators .-Consists of an instrument for determining the course of an observed ship in relation to her bearing when the range of the ship and the length of a horizontal fore-and-aft line on her are known. The ship is obset-ved through a window by means of a divided lens A, C, of which the movable part A is provided with an indicator K extending over a scale plate F. This plate is marked with a vertical scale m representing the known base lengths and co-operating with a vertically-displaceable indicator W. The plate is also marked with a range scale comprising lines radiating from a zero point j. Displaceably mounted on rollers R, T above the scale plate is an endless band M on which a horizontal line rt, equal to the breadth of the base line on the scale plate, is graduated according to the sines of angles from zero to 90‹ and the graduation marks are all joined to a point not seen in the Figure vertically below the point r. To use the instrument the half lens A is adjusted until the image of one end of the base line therein coincides with that of the other end of the base line in the half lens C. The indicator W is set to the known base length and the band M is then turned until the 90‹ line intersects the edge of the indicator W at the same point as the line on the scale g (the 14 line in the Figure) representing the known range of the ship. The desired course angle is then given by that line on the band M which intersects the indicator W at the same point as the indicator K, i.e. the 40 degree line in the Figure. When the angle subtended by the base is obtainable by separate means the divided lens may be omitted, the instrument then being provided with a subtense scale y on which the indicator K is set to the known angle. The instrument may also be used to obtain the range of a ship assuming her to be broadside on to her bearing. If the adjustment of the half lens A in this case brings the indicator K to the dotted line position K<1>, the range is given by the line on the range scale which intersects the indicator W at the same point as the indicator K i.e. in the Figure the range is 12,000 yards.
