Title: A multiple tumbling barrel machine for polishing and finishing small metallic parts and the like
IPC: B24B31/023
Filed: 1959-02-26
Abstract: 846,249. Tumbling. POLENGHI, S. Feb. 26, - 1959 [June 17, 1958], No. 6676/59. Class 60. A multiple barrel tumbling machine comprises one or more rows of rotating barrels 28, driven by a motor 14 through an endless belt 18, and a hinged support for each barrel whereby it may be disengaged from the drive without having to stop the machine. The endless belt 18, which is flat, V, or other shape, is tensioned between pulleys 16, 17 and engages suitableshaped rings 29 formed on the barrel peripheries. Each barrel-support 25 has fingers 26 provided with rubber or like rollers 27 to grip the cupshaped lower portion of the barrel so that the support and barrel rotate together about a spindle 21 which is itself pin-jointed to a fitment 20 clamped to a bar 13 running lengthwise of the machine and parallel to a bar 12 on which spindles carrying the belt guide-pulleys 19 are mounted. A spring 24 housed within the socket 23 of each spindle 21 tends to keep each barrelsupport vertical when inoperative, as when a barrel has been removed or is empty. Each conical barrel mouth is closed by a heavy cover 31, retained in position without clamping means and capable of being removed whilst the machine is in operation. When loaded with parts to be barrelled and the polishing compound the weight of a barrel causes it to assume the inclined position shown in dotted lines in Fig. 3 but locking means may be provided to keep full barrels 28 in a vertical position. If the barrels are arranged in more than one row a plurality of driving motors may be used. Barrels of different sizes, having a space relationship differing from the arrangement shown in Fig. 1, may be used ; they may also be provided with internal ribs.

Abstract: 194,715. Kautny, T. March 9, 1922, [Convention date]. Blowpipe burners.-A non-return valve is inserted in the acetylene supply pipe 7 of an oxyacetylene welding burner to prevent oxygen flowing back through the acetylene pipe if the burner nozzle becomes choked and a spring relief valve 5 is inserted on the acetylene duct to provide for the escape of the oxygen. The small contact surface of the two gases in the narrow acetylene passage prevents a quick mixture being formed and obviates the risk of explosion.

Title: Improved signal processing system
IPC: G05D3/18
Filed: 1965-02-18
Abstract: 1,063,577. Phase detectors. AMPEX CORPORATION. Feb. 18, 1965 [March 30, 1964], No. 7051/65. Heading H3A. [Also in Division G3] Two square wave pulse trains are phase compared by applying them to switch to opposite states a bi-stable circuit whose output of rectanguled pulses are then of a duration indicating the phase relation, and the difference between this output and one of the pulse trains forming a reference phase time base is then taken to form pulses whose polarity indicates the sense of the phase error of the other pulse train (as well as by their duration the magnitude of the phase error). These pulses may be integrated to form a variable D.C. voltage which, after amplifying, controls the speed of a servomotor controlling, e.g. the capstan drive of a magnetic tape recorder, and the variable phase square wave may be derived from a magnetic pick-off head coupled with a lined tachometer disc driven by the motor. The reference square wave may be applied over a series Zener diode 22, Fig. 1, limiting its amplitude, to a phase inverting transistor T1, with differentiating capacitor 44 in its collector circuit so that positive and negative pulses are produced and applied to a second transistor T2 which passes only one differentiated pulse polarity (positive). These pulses are sharpened due to an inductor 50 in the collector circuit 42, before being fed to the bi-stable circuit 108. The square wave tachometer signal may be applied to a Schmitt trigger circuit (comprising a pair of transistors T3, T4 with common emitter circuit) to produce sharpened output square waves which are differentiated by a capacitor 98 and one pulse polarity amplified by a transistor T5 with inductive collector circuit for sharpening the pulses, before applying them to the other side D of the bi-stable circuit. The bi-stable circuit output E (variable duration pulses) may be applied through a normally conducting transistor T6 to one end of a centre tapped resistance 126, 128, the other end being connected to the reference wave phase inverter T1 output, so that the centre tap output comprises pulses reversing in polarity with the sense of the phase error and of amplitude proportional to the magnitude of the error. These may then be applied to the connected bases of series conected NPN and PNP transistors T7, T8 and an amplified output taken from the centre tap of a resistance 140, 142 connected between the collectors.

Title: Method for Producing Outgassed Permanent Magnets and Neutron Generator Tube Incorporating such a Magnet
IPC: H01J27/02
Filed: 1968-02-13
Abstract: 1,189,911. Ion beam tubes. SCHLUMBERGER TECHNOLOGY CORP. 13 Feb., 1968 [13 Feb., 1967], No. 7067/68. Heading H1D. [Also in Division C7] A permanently magnetizable element for incorporation into a neutron generator tube is out-gassed by heating to a temperature above 400 C., but lower than a critical temperature, e.g. the Curie point, at which the structure of the material is so altered that the material cannot be magnetized in the absence of further heat treatment. The gas pressure is maintained at 10<SP>-5</SP> mm. Hg or less. The element is then allowed to cool and is then permanently magnetized in an applied magnetic field of, e.g. 400-800 gauss. The critical temperature is stated to be 900-1100 F. for " ALNICO " and 1800 F. for "INDOX." Ceramic magnetic material is also mentioned. The critical temperature is also stated to depend on the duration of heat treatment. The tube components other than the magnetizable element are out-gassed in hydrogen at atmospheric pressure by heating to 900 C. for an hour, but the magnetizable elements are heated in a vacuum of 10<SP>-5</SP> mm. Hg to 600 C. for an hour. All the components are then assembled, placed in the tube envelope and heated to 400 C. for fourteen hours at a pressure of 10<SP>-8</SP> mm. Hg. The tube is then sealed and the magnetizable element permanently magnetized. In the neutron generator tube shown the ion source 45 comprises a cylindrical permanent magnet and anode 57 having a massive nickel cathode 50 at one end and a second cathode 52 comprises a nickel annulus 53 and a central molybdenum plug 55 at the other. A deuterium and/or tritium gas supply 25 comprises a can 31 with a perforated end cap 30 containing a heated filament 26 coated at 44 with zirconium. A suppressor electrode is shown at 75 and the target 73 is a carbon button retained in a recess 74 of the electrode 15 by a copper mounting ring 81. The generator may be continuously operated with a gas pressure maintained at 1 micron or pulsed, the gas pressure being 10 to 20 microns.

Abstract: 571,279. Heating by electric arcs. STUPAKOFF CERAMIC & MANUFACTURING CO., May 5, 1943, No. 7110. Convention date, March 19, 1942. [Classes 39 (ii) and 39 (iii)] [Also in Group XXXV] A glower formed of material which is an insulator when cold but conducting when hot, used for example as a generator of infra-red rays, as an igniter in oil burning equipment and for illuminating purposes, is heated to render it operative by means of a self-extinguishing arc between divergent electrodes. Electrodes 7, are associated with a glower 2 so that the arc when formed may climb them and become extinguished. A transformer 5 may have a winding 4 furnishing operating current and a high voltage winding 9 producing the arc; this transformer may be arranged with a magnetic shunt 11 so that the current in winding 4 may be rendered substantially constant and the winding 9 receive insufficient excitation to re-establish the arc while current is flowing in winding 4. A transformer core 30 may comprise a number of secondary windings 32 with shunts 34 so that a number of glowers 33 may operate independently under constant current. The arc gap may be directly in shunt with the glower and high frequency current may be used to produce the arc which becomes short-circuited when the glower is in operation, Fig. 4 shows a D.C. system in which an induction coil with interrupter 26 produces the arc voltage and is disconnected by a relay 22 when the glower operates. A system in which a high frequency oscillator is coupled with a supply circuit for a glower with arc electrodes in parallel is also described.
