Abstract: 719,592. Sawing. BUNDY TUBING CO. Aug. 29, 1952, [Sept. 28, 1951.] No. 21723/52. Class 145 (2). A circular saw 15 and its driving motor 14 are fitted on a pivoted arm 12 which is interconnected through a fluid-pressure operated motor with a lever 30 linked to a clamp member 55 so that when a foot lever 80 is depressed to supply air to telescope the jack, the initial movement of the jack swings the lever 30, which offers least resistance, so that the clamp 55 lowers and draws the work, such as tubing W, against stops 10 and holds it there while the jack, reacting on the now fixed point 34, swings the arm 12 to pass the saw through the work. If there is no work on the saw table, the clamp moves through its full traverse and the saw itself does not move. The jack is indirectly connected with the arm 12 through a lever 22, the arm being pulled back against an adjustable stop 23 on the lever by a spring 20 and the lever bearing on a stop 25. A telescoping rod 40 connected to the lever 22 operates a switch 46 on the lever 30 to reverse the air supply to the jack at the end of the cutting operation. A pneumatic or hydraulic jack 73, also controlled by the foot lever 80 and the switch 46, raises and lowers a hood 60 which may also act as a hold-down for the work. An extension of the table top may be provided with an adjustable end-stop 7 and with upstanding posts aligned with the stops 10.
Patent GB-497610-A (GB)
Title: An improved process for the production of compositions of metal and metal oxides
IPC: C09C1/62
Filed: 1937-08-06
Abstract: A composition of a metal and its oxide or oxides is obtained by reducing the metal to a finely divided filamentary form and then milling the metal in that form in an oxidizing atmosphere.  Metals specified are lead, zinc, tin and aluminium, the invention being particularly described with reference to lead.  The <PICT:0497610/III/1> <PICT:0497610/III/2> lead-containing composition containing say 50 per cent lead and 50 per cent oxide may be used for the formation of electric battery plates, as a pigment or as a starting material for the production of pure higher oxides, arsenates or other compounds, litharge being obtained by roasting at 1000 DEG F. for an hour, and red lead by a much longer roasting at a lower temperature.  As shown, lead pigs 13 are fed into one compartment of a tank 3 which is divided by a wall 5 formed near the bottom with openings 6.  The tank is heated by gas burners 4 or electrically The melted lead flows through the openings 6 into the other compartment and thence via plug 10 and pipe 9 to a two part distributing device 20, 21 mounted on a shaft 16 and rotated by motor 19 through bevel gears 17.  Minute perforations are formed at meeting of the parts 20, 21, preferably by making the meeting parts of relatively small thickness, and knurling at least one of the parts as described in Specification 497,586, [Group II].  An iron float 23 closes pipe 9 when the lead has risen to the desired level in the distributing device.  On rotation of this device, the lead is forced through the perforations, being collected in filamentary form in annular tank 25 preferably containing water, heated, e.g. by gas burners 27.  The filaments which have a thickness say of ,003 inch and a length up to one inch, may be removed from the tank by a ring device 29.  The wet filaments are placed in a heated hopper and dried with agitation in the presence of air whereby a coating of oxide and hydroxide is formed which prevents balling in the subsequent milling operation. Dry filaments may be wetted and then dried, or treated with steam in the presence of air.  The coated filaments which are preferably quite dry are then milled in the presence of air or other oxidizing gas.  A suitable mill, Fig. 2, comprises an outer shell 30 and a preferably perforated inner shell 31, preferably formed with ribs or pins 32, 33 respectively. The outer shell is driven in one direction as a relatively slow speed, and the inner shell in the reverse direction at a much higher speed.  The metal filaments are fed between the two shells, or if the inner shell is perforated, into this shell from hopper 34, air being blown in through pipe 35.  The fine oxidized material passes through screen 36 into housing 37 and thence to bin 38.  The housing 37 is formed with a cloth top 38a or with a tall stand pipe, or a centrifugal separator or large cloth bag may be employed to separate the dust and air.  The metal filaments may alternatively be milled in a Hardinge or Raymond mill.

Abstract: 1513391 Colour television tubes PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES LTD 21 May 1975 [10 June 1974] 21806/75 Heading H1D In the manufacture of the screen of a shadow mask tube, in which areas of a photosensitive layer 3 on the inside of the face plate 2 are exposed in housing 1 to light through the apertures of the shadow mask 8, a single light source 4 is made, by successive exposures through an optical correction device 6 rotated through 180‹ about an axis 7 perpendicular to the face plate, to function as two virtual sources 9, 10 displaced laterally one on each side of the true source 4. By design of the correcting device 6, in conjunction with the conventional correction plate 5, the displacement of the source may be made a function of the position on the face plate of the exposed area. The true source 4 may be arranged off axis to suffer a constant physical displacement to a diametrically opposite position as the correction device 6 is rotated through 180‹ so that the device has to provide only the small correction about the mean displacement associated with the position of the exposed area on the face plate. The source 4 may be apparently enlarged by an independent small movement.

Patent GB-904633-A (GB)
Title: Air cooled surface condenser
IPC: F28B1/06
Filed: 1959-06-26
Abstract: A tubular, air-cooled, surface condenser comprises a condenser element 3 in which vapour flows downwardly, coupled in series to a reflux condenser element 6, a fan or fans 16 being arranged to blow cooling air past the tubes of both elements simultaneously. In the form shown all the steam condensing tubes are joined to a common condensate collecting header 4, <PICT:0904633/III/1> but whereas the tubes 3, forming the major part of the tube assembly, are connected at their upper ends to a steam inlet header 2, the reflux condenser tubes 6, forming a relatively small group, are connected at their upper ends to a header 7 which is connected through an after cooler 10 with the air suction line 11. Hence, uncondensed vapour in condensate header 4 is drawn upwardly and condensed in reflex condenser tubes 6.  Any uncondensed vapour which reached header 7 is forced by a steam-fed ejector 9, back into steam inlet header 2. Uncondensed vapour and air not so ejected into the header 2, is extracted by the vacuum line through the aftercooler 10.  Condensate from the aftercooler flows by way of conduit 12 and syphon 13 to the condensate outlet line 5.  The steam supply valve 15 to the ejector 9 may be so controlled, e.g. in dependence on the pressure in the condensate collecting line or in the header 7, that the suction capacity of the device 9 is automatically adapted to different loads and/or different cooling air temperatures.

Title: Improvements in or relating to electric control means for regulating the speed of two independently power driven mechanisms
IPC: H02P5/52
Filed: 1945-08-28
Abstract: 634,294. Automatic control systems for aircraft. FAIREY AVIATION CO., Ltd., EBEL, F. L., and LISLE, W. G. Aug. 28, 1945, No. 22124. [Class 38 (iv)] The movements of two independently power-driven mechanisms, e.g. aircraft wing flaps are synchronized by means of two rotary switches driven by each flap through gearing. Lack of synchronizm causes phase displacement of the rotary switches, which produces a corrective stoppage of the flap over-speeding. As shown, Fig. 2, (showing the schematic system for one flap), the rack C, driven from the hydraulic jack operating the flap, drives rotary switches h, n through shafts e, k and gears d, f, j. The hydraulic system moves the flaps up or down in response to a valve, as described in Specification 634,293, [Group XXIX], controlled by solenoids u, v, energized by battery 22. Switch h comprises disc g on which are mounted circumferentially, contact strips o, p, separated by insulating blocks q, r and four fixed contact pieces w, x, y and z, the relative angular spacing of which (being less than 180 degrees) corresponds with the flap positions " housed," " cruising," take off " and " landing ". Switch n comprises a disc m, the periphery of which carries contact strips 23, 24, 25, separated by insulating blocks 27, 28, 29, and four equally spaced fixed contact pieces 35, 36, 37, 38. Strips 23, 24, 25 are connected by lines 31, 34 and 32, 33 respectively, with the four corresponding strips on the switch n of the apparatus at the other side of the aircraft. The solenoids u, v are connected to the negative pole of battery 22 through switch n and to the positive pole through switch h and the manual selector switch 19, the contacts 15, 16, 17, 18 of which are connected to the fixed contacts w, x, y, z on both sides of the aircraft. In operation the switch 19 is moved to the position corresponding to the required flap position and the appropriate solenoid is thereby energized. Movement of both port and starboard hydraulic jacks is initiated, with the consequent rotation of both sets of rotary switches. With the flaps moving synchronously, the motion continues until the block r reaches the energized contact w, x, y or z, according to the position of switch 19, when the current to solenoid u or v is broken simultaneously in both flap systems. If the flaps do not move in synchronizm one set of rotary switches will move more rapidly than the other and the switches n will not remain in phase. The solenoid of the system associated with the over-speeding flap is thus open-circuited while that of the slower flap remains connected to the battery. When positional correspondence is resumed, the joint movement continues.
