Patent GB-845300-A (GB)
Title: Improvements in or relating to shearing apparatus
Inventor: PENKALA EMIL
IPC: B23D21/00
Filed: 1957-03-11
Abstract: 845,300. Shearing. METAL TRIM Ltd. Jan. 1, 1958 [March 11, 1957], No. 7920/57. Class 83 (4). [Also in Group VIII] In shearing apparatus e.g. for cutting metal and plastics comprising co-operating fixed and movable dies having coincident openings corresponding to the shape of a profiled section, the movable die is mounted on a carrier member movable by downwardly applied force to shear the section and supported from a base member by elements which, on downward movement of the carrier effect lateral movement of the latter by toggle action so that the resultant shearing action is at an angle to the vertical at all parts of the section. Cold-rolled channel sections issuing directly from the rolling mill are sheared by a movable apertured die 11 mounted on a carrier 12 slidably disposed between frame members 1 and 2, the die 11 cooperating with a fixed apertured die 8 carried in a mounting 9 fixed to the member 2. On downward movement of the carrier 12 by pressure applied to a member 22 the bottom of the carrier forces rollers 14 between rollers 15 so that the carrier is moved laterally by toggle action, the resultant shearing action thus being inclined to the vertical and to the long dimensions of the section. End rollers 14, 15 respectively engage a depending portion 19 of the carrier 12 and a fixed abutment 16. The lower rollers are supported on recessed blocks 17 slidable on a base 4 and all the rollers are spring loaded. Rollers 23 permit relative movement between the carrier 12 and the pressure-applying member 22. The carrier is returned after shearing by a spring 26 which acts on a crossmember 29 carrying pivoted members 30 with rollers 31 engaging arcuate recesses 32 in the carrier. A stop member 35 prevents excessive rise of the carrier member, stops 33 locate the carrier laterally and maintain the dies coincident when not shearing and a stop 36 prevents vertically downward movement of the carrier while permitting movement of the carrier downwardly to the right by the toggle rollers. In a modification, Fig. 5, the movable apertured die 11 is supported by two spaced assemblies of rollers 14, 15, vertical pressure being applied through spaced series of rollers 23. When not shearing the carrier 12 is held against a stop 39 and a spring-loaded pivoted stop member 41 by inclined springs 42. The number of stages in the toggle assemblies may be varied to alter the angle of movement of the carrier and the assemblies may comprise articulated members instead of rollers. In the embodiment of Fig. 5 the dies may have separate apertures for simultaneously shearing a number of sections. Specification 588,230 is referred to.

Filed: 1953-03-23
Abstract: 732,166. Burner apparatus. SOLAR AIRCRAFT CO. March 23, 1953, No. 7988/53. Class 75 (1). [Also in Group XII] A combustion equipment, for example, reheat combustion equipment of a jet propulsion engine, comprises a duct through which a high velocity gas stream flows, a fuel distribution grid, a second grid downstream of the first having a fuel and gas mixing channel and a flame holding channel, and a supplementary flame holding channel downstream of the second grid. The fuel distribution grid comprises three concentric annular manifolds 38, 41, 42 and radially disposed pipes 36, 37, 43 all disposed in a common plane. The pipes 36, 37 intersect at the centre, and the pipe 36 is connected to a fuel supply at 53. The pipes 43 connect the manifolds 38, 41. All the manifolds and pipes are formed with fuel outlet nozzles 44 at the upstream side thereof. The second grid comprises inner and outer rings 56, 55 which are in line with the manifolds 41, 38 respectively. The rings are each formed by annular portions 58, 57 spaced apart by means of a trough-shaped part 61 which forms upstream a carburation channel 63 and downstream a flame holder channel 62. The inner and outer rings 56, 55 are connected by four radial members 66 which are similarly formed to provide upstream carburation channels 63 and downstream flame holder channels 62. The trough-shaped partition walls 61 have openings 72 to permit fuel and gas mixture to enter the flame holder channels 62. Those portions of the fuel pipes 36, 37 upstream of the radial members 66 have downstream-directed fuel discharge openings 69 which discharge fuel into the carburation channels 63. The circular pipes 38, 41 also have downstream-directed fuel discharge openings 71 to direct pilot fuel into the circular carburation channels 63 of the rings 55, 56. The openings 69, 71 may alternatively be directed upstream, the pilot fuel being carried by the gases into the carburation grooves. The supplementary flame holding channel comprises a ring member 82 of V-section with the open part of the limbs downstream. The V-section ring is disposed downstream radially between the rings 55, 56 and is connected by means of plates 85 and channel-section members 84 to the radial members 66 of the second grid. A pair of igniters such as sparking plugs 73, 74 project into the outer annular flame holding channel 62. The primary pilot combustion flames issuing from the flame holders 62 are indicated at 80, and the second pilot combustion flame issuing from the supplementary flame holder 82 is shown at 87, the pilot flames serving to initiate the main combustion in the fuelexhaust gas mixture. The main combustion flame front indicated at 89 does not tend to retreat downstream.

Title: Improvements in or relating to circuit arrangements for alternately rending conducting two rectifying circuits connected in parallel and in opposition
IPC: B23K11/24
Filed: 1966-02-24
Abstract: 1,137,108. Control systems for resistance welding apparatus. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 24 Feb., 1966 [27 Feb., 1965], No. 8172/66. Heading H2H. A circuit arrangement for rendering conductive a pair of reverse parallel connected rectifying devices-such as ignitrons-comprises means whereby the rectifying devices cannot be made conductive until the anodes thereof have become positive relative to the cathodes. Resistance welding apparatus is supplied from a transformer 1 which is energized from an A.C. supply 2 by way of a pair of reversely connected ignitrons 3, 4. Firing potentials for the igniting electrodes are obtained from a circuit which includes transistors 16, 25, 29 controlled by a square wave voltage generator 28 and these potentials are applied to the igniting electrodes by way of a circuit which includes a silicon controlled rectifier-or thyratron-29. Transistor 29 is rendered conductive by the output pulses from generator 28 and whilst conductive inhibits conduction of transistors 25, 16. When the anodes of ignitrons 3, 4 are positive relative to the cathodes a voltage is produced by transformer 36 and rectifier 33, 34 which renders transistor 29 non-conductive. Transistors 25, 16 are not rendered conductive by the output pulses of generator 28 whereby pulses are produced in the secondary winding 15 of transformer 14 which are applied to the controlled rectifier 10 causing it to conduct to energize alternately the igniting electrodes of the ignitrons 3, 4. Malfunctioning of the arrangement causes a relay 20 to be energized to operate safety devices or indicators. With a highly inductive load such as the transformer 1 in which the voltage current phase angle is, say, 60 degrees, the firing angle of the ignitrons must be at least equal thereto for satisfactory operation of the circuit arrangement. In other embodiments certain of the circuit components are omitted such as the amplifying transistor 25 and the ignitrons 3,4 may be replaced by a bridge of rectifiers, the controlled rectifier 10 being across the D.C. diagonal thereof, or by a pair of reversely connected thyristors.
