Title: Improvements in or relating to a threading unit for use with a workpiece holder
IPC: B23G1/04
Filed: 1953-11-09
Abstract: 747,357. Screwing. SHEFFIELD CORPORATION. Nov. 9, 1953 [Nov. 18, 1952], No. 30932/53. Class 83 (3). A machine for screwing or tapping comprises means 21 on a spindle 16 for detachably connecting a threading tool 15, drive means 35 on means 42 which supports the spindle for sliding movement and rotates it always in the same direction, a lead unit including a screw 18 fixed to the spindle, means 106 for disengaging the lead unit, and a return mechanism 61, 62 for rapidly returning the spindle after a threading operation. A key 43 in the spindle 16 conveys the rotary motion from the sleeve 42 and permits the sliding movement. The worm-wheel 35 is rotated by a motor 2A through a belt 26 and change gearing 30 ... 32. The spindle is rapidly returned after threading by a motor 1A driving through a chain 56, a planetary gear clutch 65, 66, 67, 70, the pinion 61 and the rack 62 on the spindle. With a brake 72 engaged, the gear 65 rotates the wheel 67 to return the spindle. With a brake 74 engaged, the wheels 65, 66, 70 rotate idly and the spindle is held fast, thus allowing the unit to be mounted vertically. In operation, motor switches are pressed to start the motors 1A, 2A and a cycle-start-switch is pressed to energize a solenoid to move the yoke 106. The yoke 106 carries with it a sleeve 102 having a cam surface to close nut-segments 19 on to the lead screw 18. A solenoid is also actuated to release the brake 74. The spindle advances together with the die head 15 which is opened and closed by abutments on a rod 112. An adjustable abutment 90 carried along with the spindle actuates a switch 109 at the forward limit of movement to move the yoke 106 and release the nut segments. Movement of the yoke 106 also actuates a switch 120 to operate the brake 72, causing the spindle to be returned. At the rear limit a further adjustable abutment 91 actuates a switch 110 which de-energizes a solenoid to allow the brake 74 to be applied by spring means, thus holding the spindle against axial movement. This brake is also applied automatically in the event of power failure, or by pressure on a stop-button which cuts off all current. Lubricating machines.-A cam-driven pump 29 in a sump in a casing 13 supplies oil to a bearing 51, to the spindle and, if desired, to the lead unit. The spindle 16 is helically grooved externally and the sleeve 42 internally, for lubrication.

Title: Improvements relating to the production of iron and steel
IPC: C21B13/12
Filed: 1952-12-05
Abstract: 717,957. Manufacture of iron. KOCKS, F. Dec. 5, 1952 [Dec. 8, 1951], No 30964/52. Class 72 A process for the manufacture of iron directly from iron ores using molten high carbon iron as the reducing agent in an electrically heated furnace comprises adding a mixture of iron ore and slag-forming materials to the molten iron at the rate at which they are consumed, and tapping the iron slag continuously or periodically, the carbon content of the molten iron being maintained by the solution of one or more carbon rods which dip into the metal and are not connected to any source off electric current. As shown, the ore and slag forming materials are fed into the furnace through openings 18, 19 on to the surface of molten iron 20. A carbon rod 21 having its end below the surface of the metal is dissolved and maintains the carbon content of the iron sufficiently high to reduce the ore. The rod may be raised while ore is added to reduce the carbon content to a desired value and then the metal may be tapped or high carbon metal may be tapped continuously and later refined to the required carbon content. An induction furnace may be used.

Title: Fuel mixture control for internal combustion engines
IPC: F02D9/00
Filed: 1922-11-13
Abstract: 211,209. Commercial Cars, Ltd., and Thomas, E. W. Nov. 13,1922. Interconnecting two - valve members. - A valve for controlling the supply of gas or combustible mixture to an engine and a valve for controlling the air supplied to the induction pipe, are moved, in unison by a single control, during part of the range of movement, whilst at one or other end of the range one valve is adapted to be moved independently of the other so as to enrich the mixture. The gas-control valve 2, Fig. 3, and aircontrol valve 3 to the induction passage 38 are provided at one end of their spindles 4, 5 with arms 8, 9, 10, 11 carrying adjustable set-screws 12 which engage with lugs 13, 14 to limit the movements of the valves. Arms 15, 16, Fig. 2, are rigidly secured to the other ends of the spindles 4, 5 and are drawn together by a spring 20. Arms 21, 22 are freely mounted on the spindles and are connected by a link 23 the point of attachment of which to the spindles can be adjusted for example by a clamp 31 and holes 30. Lugs 24, 25 on the arms 15, 16 are adapted to contact with the loose arms 21, 22, to keep the arms 15, 16 a predetermined distance apart and this distance may be adjusted by a screw 32 in the lug 24. An actuating arm 26 is formed integrally with the loose arm 22 and another loose arm 34 carries a dog 35 adapted to engage an extension 36 rigid with the spindle 5. As the arms 26, 22 are moved in a clockwise direction the link 23 moves arm 21 which contacts with lug 24 and causes the gas valve to open. This movement of the valves in unison continues until the air valve is stopped by screw 12 meeting the lug 14. Continued movement of lever 26 then causes further movement of the gas valve against the action of spring 20. In the reverse direction, the air valve may be moved still further towards its closed position after the gas valve is closed by the lever 22 striking the lug 25. At starting, the air valve may be held closed while the gas valve is opened by moving the lever 34 so that the dog 35 engages the extension 36 on a member 37 rigid with the air-valve spindle. The controlling lever might be mounted upon the gas-valve spindle or upon a separate spindle mounted on the casing. Pointers 27, 28 on the arms 15, 16 may work over scales 17, 18 to facilitate adjustment and re-assembling of the parts and a chart may be provided giving the positions of the respective pointers for a particular strength of mixture, size of fuel jet or choke tube.

Title: Improvements in or relating to oscillating damping suspension systems for road vehicles, and for generating storable compressed air
IPC: F16F9/02
Filed: 1947-11-25
Abstract: 641,367. Gas compressors. FARRER, J. O. (Navarro, M., Llovet, E. J., and Llovet, A. E.). Nov. 25, 1947, No. 31245. [Class 8(i)] [Also in Group XXXII] An oscillating damping suspension system for road vehicles (see Group XXXII), also comprises means for generating storable compressed air during relative oscillation of the vehicle frame and wheel axles. In the arrangement shown, a pair of recesses located on either side of a central recess 2 in a casting block 1, each comprises upper, intermediate and lower chambers 3, 4 and 5 respectively, in which are slidably housed pistons 19, 28 and 31. The piston 19 which is connected by a piston rod 20 to a vehicle frame member 14, is provided with valved passages 27 whereby during relative oscillating movement of the vehicle frame and axle, air which is drawn into the upper part of chamber 3 through valved intake pipes 24, is compressed during the upward stroke of the piston 19 and is impelled through passes 27 to a zone 3a, from which it is subsequently forced through valved passages 29 in the piston 28 into a zone 4a of chamber 4, during downward movement of piston 19. Continued downward movement of piston 19 forces the compressed air through valved passages 30 in the piston 31, the subsequent downward movement of which against a spring 40, expels the compressed air through a non-return valve 43 and conduits 44, 45 to a storage tank on the vehicle. Axial alignment of pistons 19 and 28 with piston 31 during movement of the former into the chambers 4 and 5 respectively of the recess, is maintained by stems 35 and 37 on the pistons 19 and 28 which respectively engage recesses 36 and 38 formed in pistons 28 and 31. The compressed air stored in the tank may be used for recharging the pneumatic tyres of the vehicle.

Title: Improvements in or relating to the production of records of objects or pictures by scanning processes
Inventor: HORNER REGINALD GEOFFREY
IPC: G03B27/72
Filed: 1953-11-13
Abstract: 753,340. Copying by scanning. ILFORD, Ltd. Dec. 14, 1954 [Nov. 13, 1953], No. 31552/53. Class 40 (3). In an arrangement for producing a copy record of an object or picture using electrooptical scanning to produce signals representative of the latter which are then employed to produce the copy record the effect of spurious signals (e.g. the " smearing " effect of the " after-glow " light in "flying-spot" " scanning systems) is reduced by effecting a relative rotation between the direction of scanning and the object or picture and a similar relative rotation between the copy record and the copy producing means. In this manner uniformity of " smearing " results instead of " smearing " only in the direction of scanning. Fig. 1 shows one embodiment in which the picture to be copied, comprising a transparency 5, is mounted in fixed relationship with a sensitive photographic film 6 on an annular support 9 which is rotated by means of a motor 10 so that the direction of the scanning lines of the stationary raster produced by, the flying-spot scanner tube 3 rotates with respect to the transparency 5 and sensitive film 6 (following usual practice the light transmitted through the sensitive film is arranged to modulate the beam of the tube 3 by means of a photo-electric cell 7 and amplifier 8). In a second embodiment the transparency and sensitive film are stationary and the scanning coils of the flying-spot cathode-ray tube are arranged to rotate to produce rotation of the scanning raster (Fig. 2, not shown). Alternatively the rotation of the raster may be effected by the application of suitable waveforms to the deflecting elements (coils or plates) of the flying- spot tube or by the use of moving optical devices.
