Title: Lubricating grease compositions
Inventor: ARMSTRONG JACK WILLIAM
Filed: 1956-06-20
Abstract: A lubricating grease composition comprises a lubricating oil, an inorganic gelling agent and from 1 to 20 per cent based on the weight of the gelling agent of a thermosetting resin, the final stage of the polymerization of said resin preferably taking place on the surface of the gelling agent.  The lubricating oil may be a mineral oil or a synthetic oil, e.g. the esters of phosphorus- or silicon-containing acids or aliphatic dicarboxylic acids, but halocarbon, especially fluorocarbon oils and organo-silicone polymers, which are extensively described, are preferred.  The gelling agent may be an amorphous colloid, e.g. silica, alumina, magnesia, ferric oxide, nickel sulphide or a clay, e.g. bentonite. The thermo-setting resins are chosen from the products of the polymerization of an aldehyde, e.g. formaldehyde, acrolein, furfural, crotonaldehyde, and acetaldehyde with either a phenol, e.g. resorcinol, the cresols and alkyl phenols such as t-butyl and t-amyl phenol or an amino compound, e.g. urea, melamine, thiourea, aniline, benzene and toluene sulphonamides, alkyl substituted ureas and guanidine.  In examples lubricating compositions are described consisting of: (a) dimethylsilicone oil, clay and phenol-formaldehyde polymer; (b) methylphenyl silicone oil, silica gel and ureaformaldehyde polymer; (c) unspecified oil, Hectorite clay, melamine-furfural resin.  These greases are contrasted with similar greases wherein the resin is replaced by a linseed oil modified alkyd, polystyrene, polymerized diallyl-phthalate or nylon.  Specification 736,270 is referred to.ALSO:A lubricating grease comprises a silicone oil, an inorganic gelling agent and from 1 to 20 per cent based on the weight of the gelling agent of a thermosetting resin, the final stage of the polymerization of said resin preferably taking place on the surface of the gelling agent.

Patent GB-370757-A (GB)
Title: Improvements in work-feeding mechanism for sewing machines
IPC: D05B27/04
Filed: 1931-07-03
Abstract: 370,757. Sewing-machines. FAIRWEATHER, W., 65, Chancery Lane, London.-(Singer Manufacturing Co. ; Elizabeth, New Jersey. U.S.A.) July 3, 1931, No. 19190. [Class 112.] Feed by dogs ; feed by devices engaging the upper surface of the work ; by needles; needles, vibrating laterally; presser bars with periodic control.-An upper four-motion feed foot cooperates with a lower four-motion feed dog and the mechanism for alternately raising and lowering the feeding foot and presser foot is designed to overcome inertia and failure to engage the work at high speeds. The needle bar 12 is reciprocated by a link 10 from the crank disc 9 on the main shaft 8 in the usual way. The needle bar reciprocates in lugs 14 in a frame 15 arranged to swing on a pivot 16 to impart jogging movement to the needle. The jogging movement is imparted by the usual rock shaft 18 and crank arm 19. A tubular feed-bar 21 is journalled in the lower lug 14, this bar carrying the feed foot 22, apertured to permit passage of the needle. The bar 21 is engaged by a rod 25 pressed downwards by a spring 23, the tension of which is regulated by a screw 27, Fig. 2. The feed bar thus partakes of the jogging motion of the needle bar and helps to relieve the needle of strain. In Fig. 1, the feeding foot 22 is shown in its lowered position in engagement with the lower feed dog 4, at the beginning of the workadvancing movement of the feed members, the presser foot 42 being raised clear of the work support. As the feed members approach the end of their work-advancing movement, the rock shaft 49 is moved in a direction to lower the free end of the crank arm 48, so swinging the lever 32, 33 about its fulcrum stud 311 on the link 31. This movement of the lever 32, 33 is aided by the flat spring 56 and results in a downward movement of the presser bar 39 until it presses on the work. This position is reached at the end of the feeding movement. The fulcrum of the lever 32, 33 is then automatically shifted from the fulcrum stud 311 to the pin 35 so that further downward movement of the link 45 moves the lever 32, 33 about the pin 35, thereby lifting the feed foot 22 against the pressure of the spring 23. The feed foot, while lifted clear of the work, is returned to its forward position by the return jogging movement of the frame 15. The rockshaft 49 is then oscillated in the opposite direction by the eccentric 55, thereby rocking the lever 32, 33 in the opposite direction about the pin 35 to effect a downward movement of the fulcrum stud 31<1>. This causes the feeding foot 22 to be relowered to its work-engaging position ready to repeat the cycle.

Title: Improved device for providing high intensity electrical fields to accelerate charged particles
IPC: H05H5/06
Filed: 1959-06-04
Abstract: 900,781. Discharge apparatus. GENERAL DYNAMICS CORPORATION. June 4, 1959 [June 23, 1958], No. 19210/59. Class 39 (1). An arrangement for producing a high voltage electric field in a charged particle accelerator or gaseous discharge device comprises a plurality of separate low voltage primary circuits coupled to the secondary circuit formed by the particle or discharge path, and a conducting shield which confines all the flux generated within a defined volume. All the primary circuits are closed simultaneously and the total voltage generated equals the sum of the individual voltages induced. In Fig. 1, a toroidal discharge tube 10 is surrounded by a succession of cylindrical segments 12 which form the primary windings of primary circuits including coaxial cables 14, capacitors 16 and switching means 18, e.g. ignitrons, thyratons or spark gaps. One end of each segment 12 is grounded to a common point and connected to the outer conductor of a coaxial cable 14. A flat can 20 confines the flux on the outside of the toroid. Preferably, the can 20 clears the segments by a distance equal to the major radius a of the toroid minus the minor radius b of the segments 12. In Fig. 2, the coaxial cables are replaced by parallel plate transmission lines 22, 28. Plates 22 are connected to the bottom of the shield 20a and serve also to support the segments 12a. The plates 22 are connected to arcuate plates 26 which are connected to a plurality of supply cables 32 to reduce the inductances of the circuits. Horizontal plates 30 are connected to the lower edges of the plates 26 and 28. A ring-shaped shorting strap 34 connected to the plates 28 prevents insulation breakdown in the event of one of the voltage sources failing to operate. In Fig. 4, a linear discharge tube 38 is surrounded by a cylindrical shield 40 and the primary voltage circuits are constituted by segments 42, grounded discs 44 and discs 46 which are connected to the supply cables 48 via the flanges 50. In both Figs. 2 and 4 gaps may be provided in the conducting shield, as at 51, Fig. 5, to provide access to the discharge tube. In Fig. 7, the electric field induced by each segment 42b is split up into a series of sequential fields by tubular conductors 54 separately grounded to the shield 40b. In applying the invention to a charged particle accelerator, the cylindrical segments may be either pulsed by separate voltage sources or by one voltage source.

Title: Apparatus for electron beam irradiation
Inventor: DAVISON WILLIAM HENRY THOMAS
IPC: H01J33/04
Filed: 1969-04-16
Abstract: 1,241,371. Electron beam irradiation apparatus. T.I. (GROUP SERVICES) Ltd. 14 April, 1970 [16 April, 1969], No. 19316/69. Heading H1D. The window of an electron beam irradiation apparatus comprises an electron permeable membrane of titanium or aluminium adapted to withstand atmospheric pressure, and a second membrane spaced from the first and permeable to electrons and to gas. The second membrane may be a mesh of aluminium, titanium, nickel, stainless steel, or non-metallic material and a cooling gas may be circulated between the membranes without disturbing the irradiated material, which may be paint. Preferably, the gas flow is achieved by providing equal and opposite and negative pressures along two edges of the membrane, so that the mean pressure on one side is the same as that on the opposite side, e.g. atmospheric pressure, and the gas flow should be in the same direction as that of the work. The second membrane should absorb less than 50% and preferably less than 30% of the incident electrons and should have apertures less than 5 mm. across. The membrane may include wires that absorb substantially all incident electrons, in which case the area of the membrane should be not less than 80% open. Alternatively, a better distribution of the electron dose in the work may be achieved if the solid parts of the membrane are so thin that the total mass thickness of the solid parts, together with the cooling gas and the first membrane is less than half the range of the electrons used (which is proportional to the mass traversed). In this case the area of the solid parts should be 40-60%.

Title: Improvements relating to circuits for establishing a d.c. component in electrical signals
Inventor: LEE DAVID FREDERICK
IPC: H04N5/16
Filed: 1949-07-27
Abstract: 680,544. Television. ELECTRIC & MUSICAL INDUSTRIES, Ltd. July 19, 1950 [July 27, 1949], No. 19707/49. Class 40 (iii). A circuit for levelling electrical signals in a channel at a point where the peak-to-peak level of the signals is inadequate for direct levelling, the signals including recurrent datum portions which in the absence of distortion should have a uniform level, comprises a subsidiary amplifier fed with signals tapped from the channel and means for developing a signal proportional to the difference between the level of the datum portions and the mean level of the signals at the output of the amplifier, and means for applying a fraction of the developed signal to the channel to bring the datum portions of the signals therein to a uniform level. As illustrated, the invention is applied to a television system where it is desired to apply signals from a point 2 in the main channel 1 to a monitoring channel 3, the peakto-peak voltage of the signals at point 2 being of the order of only 1 volt. Connected to point 2 is an amplifier stage 6 having a gain of the order of 12, the amplifier feeding a rectifier stage which develops a current in the loop 13- 16 proportional to the difference between the levels of the extremities of the synchronising pulses and the mean level of the signals at the anode of stage 6. This current is representative of the D.C. component of the signals and that fraction of the potential developed across resistors 14, 15, 16 which appears across resistors 15 and 16 is applied in series with resistor 5 in the coupling circuit 4, 5 between point 2 and the monitoring channel. The fraction is made adjustable by resistor 15, the necessary value being of the order of the reciprocal of the product of the gain of the amplifier stage and the efficiency of the rectifier stage. Point 17 returns to a bias potential. Condenser 19 smooths the potential developed across resistors 15 and 16. In an alternative arrangement a fraction of the whole of the amplified signals after the D.C. component has been established therein in a conventional manner may be fed to resistor 5.
