Title: A system for controlling the supply of power to a load through electric discharge apparatus
IPC: H02M1/02
Filed: 1942-08-07
Abstract: 562,640. Control systems for resistance welding etc.; converting by discharge apparatus. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. Aug. 7, 1942, No. 11094. Convention date, Aug. 13, 1941. [Class 38 (iv)] Current supply from an A.C. source to a load circuit is controlled by one or more ignitrons each having an immersion ignition electrode and a control member. Impulses tending to make an ignitron conductive are continuously supplied to the igniter, means being included for displacing the phase of the impulses to determine the average value of current to be transmitted, and a bias potential is applied to the control member to maintain the ignition in non-conducting condition and varied to permit conduction. Timing means may be provided to determine number of current cycles transmitted to the load. The Figure shows ignitrons 17, 19 reversely connected in parallel to supply A.C. to a transformer 11 feeding a welding load 7. Closure of the supply switch 143 energizes the anode circuit of the ignitrons and a peaking transformer 29 supplies impulses at an instant in each half-cycle determined by a phase shifting circuit 39 to the igniters 25 in turn. A holdoff bias voltage is also applied to control grids 27 through a tapping 55 on resistance 53, tapping 73 on resistance 75, conductor 83, potentiometer tap 71 and adjustable tapping 59 on resistance 57. A switch 145 starts welding current by energizing relay 81, Contact 79 connects a thyratron 77 in series with resistance 75 across the potentiometer and a contact 99 renders operative impulses from a transformer 97 at a phase determined by a thyratron 105 with its grid connected to a phase shifting circuit ; these impulses cause tube 77 to conduct, whereby a potential is developed in resistance 75 which changes the bias voltage on the control grids 27 to permit the ignitrons to pass current. At the same time a timing condenser 125, connected in parallel with resistance 75 through resistance 127, commences to charge and the voltage on the grid of a thyratron 129 eventually reaches a value at which this thyratron, which is in parallel with part of the potentiometer 65, becomes conductive, whereupon the thyratron 77 ceases to conduct and the hold off voltage is reapplied to the grids 27. Release of the switch 145 causes contact 139 to discharge the timing condenser 125 and reset the apparatus.

Abstract: Apparatus for applying wax to a yarn comprises a support which rotates a block of paraffin wax about an axis, a first spring which urges the block along the axis towards the unsupported end of the block and against both an impact member which substantially bears the force of the spring, and a further member urged by a second spring against the unsupported end of the block, the yarn passing between the further member and the block.  The further member comprises a generally circular plate having at one side a circular recess in which the impact member is situated.  The end of the second spring remote from the block bears against a rotatable helical cam member so that the spring force is adjustable.  The apparatus may be positioned in an automatic winding machine having a plurality of winding stations moving relative to a tender.  The tender can actuate a lever mechanism to move the impact member and thus the wax block against the first spring so that a yarn can be inserted.  A spring is provided to return the impact member to its normal position.  The support for the block of wax has a pulley disc driven by a belt and is secured either directly or through a clutch thereto.  The clutch is disengaged by an electromagnet when a yarn feeler senses the absence of a yarn.  The support is pivotably movable out of the belt engaging position into a wax block replacing position by a mechanism actuated when a feeler detects that the block is almost depleted. The tender replaces the block.

Abstract: 1,269,586. Compacting waste material in containers. KYSOR INDUSTRIAL CORP. 9 March, 1970 [14 March, 1969; 12 Nov., 1969], No. 11278/70. Heading B8C. Apparatus for compacting waste material comprises a generally rectangular ram chamber 10 having a top charging opening and a ramming port 29 in one side beneath a rigid header bar 23, and a rectangular ram 16, 18 which is movable with a sliding fit across the bottom of the chamber and outwardly thereof beneath the bar 23 and through the port 29 so as to extend into a container 12 releasably fastened to the chamber 10 for packaging and which is composed of two superposed, relatively slidable, sections 16, 18. A frame 15, rigid with the chamber 10, incorporates guideways for the complementary ram sections 16, 18 and accommodates hydraulic cylinders 21, 22 and 24 respectively for individual operation of the ram sections 16, 18. The total height of the ram sections 16, 18 is less than that of the ramming port 29 to provide an overclearance "X" so that the machine can clear itself of large incompressible materials. The lower ram section 16 has a projecting portion 30 which is adapted to compress and raise the contents of the container, detents 31 and brackets 32 being provided on the front face of the ram to facilitate the fitment of pinning rods across the opening of the container. Abutments 36, 38 respectively on the upper and lower ram sections 18, 16 limit the extents which the upper ram section 18 can lead, and trail, the lower ram section 16, a hook 42, fast on a bar 44 rockable in the lower section, being engageable within a keeper 40 secured beneath the upper ram section 18 when the latter is in its foremost projected position with respect to the lower section, the arm 45 being lifted by a shoe 46, when manually raised by a handle 51 and when the ram section 18 is projected sufficiently. High and low-hydraulic pressures from supplies PF2, PF2, Fig. 6, not shown, are directed respectively through control valves (65, 75) to move the rams into and out of the form chamber 10, and, if forward movement is arrested, by an incompressible load the rise in pressure in the high pressure supply (PF2) causes the supply to the cylinder 24 to be dumped so that the lower ram 16 moves forward to the limit of its stroke or to an extent permitted by the lost motion between the abutments 36, 38. If the apparatus remains jammed the upper ram section 18 remains stationary and the lower section 16 is retracted until it contacts the abutment 36 and the latch 42 engages the keeper 40, if the handle 57 is operated to raise the shoe 46, whereupon full power from both sources (PF1, PF2) is restored to all three cylinders (21, 22<SP>1</SP>, 24<SP>1</SP>) to move the ram sections forward in unison.

Title: Improvements in fluid control valves
IPC: G05D7/01
Filed: 1945-05-05
Abstract: 624,167. Valves. S.A.T.A.M. SOC. ANON. POUR TOUS APPAREILLAGES MECANIQUES. May 5, 1945, No. 11484. Convention date, Sept. 14, 1943. [Class 135] A valve for limiting the rate of flow of fluid in a conduit comprises a housing having an inlet 12, Fig. 1, and provided. with a movable assembly constituted by a valve member 1, having a threaded extension downstream of its seating 5 on which is mounted a velocitysensitive disc 9, and which has a pin and slot connection 7 with a spring-loaded piston-like member 2. The members 1, 2 are urged apart by a spring 4. The fluid pressure above the member 2 acts to open the valve and is communicated through an orifice 23 to a chamber below the member 2, the pressure in which may be regulated, to control opening and closing of the valve, by a valve in a conduit 11 leading either to a vessel containing fluid at a pressure lower than that in the inlet 12 or to a point downstream of the valve member 1. When the valve member 1 is open, the fluid flowing past the disc exerts a force thereon tending to close the valve member with increasing flow. In a modification, the chamber below the piston 2, Fig. 2, communicates with the inlet through a valved-conduit 17 and with the outlet through a passage 16 and past a spring-loaded ball valve 13 attached to a disk 9. Thus, as the flow increases the disc 9 tends to close the valve 13 resulting in an increase in pressure on the lower side of the piston 2, tending to close the valve member 1. The Specification as open to inspection under Sect. 91, comprises also a modification in which the disc 9 is dispensed with and the pressure in a Pitot tube upstream of the valve is applied to the chamber below the piston 2, the pressure in this chamber being regulated by a valve in an outlet conduit therefrom. This subjectmatter does not appear in the Specification as accepted.
