Title: Improvements in or relating to pumping apparatus for liquids
IPC: F04B49/16
Filed: 1929-05-21
Abstract: 333,644. McGregor, R. May 21, 1929. Crank-actuated pumps; air vessels; indicating action of; regulating delivery by secondary piston in pump barrel.-A pump suitable for supplying fuel to a carburettor comprises one or two barrels 1 in which plungers 2 are reciprocated by a crank pin 19 through a slider 18 and a yoke 14. The delivery is controlled according to the difference between the pump output and consumption by means of a floating piston 7 which, during its movements in phase with the plungers 2, renders the strokes of the latter ineffective. These movements are regulated by a cam 5 which passes through a slot in the piston 7 and is connected to a spring-controlled piston 4 working in a cylinder 3 connected to the carburettor &c. The plungers 2 deliver through valves 12 and passages 11 to the cylinder 3, and any excess of delivery over consumption raises the piston 4 and cam 5, thereby increasing the stroke of the piston 7 and reducing the output to correspond to the consumption. The movement of the piston 4 may operate a consumption indicator.

Title: Improvements in or relating to induction machines
Inventor: LAITHWAITE ERIC ROBERT
IPC: H02K41/025
Filed: 1959-05-09
Abstract: 883,837. Linear motors. NATIONAL RESEARCH DEVELOPMENT CORPORATION. April 27, 1960 [May 9, 1959; Jan. 28, 1960], Nos. 15973/59 and 3076/60. Class 35. In an induction-type linear motor in which the magnetic field travels inwardly from each end to sustain an oscillating motion, the stator is so wound that the magnetic field in the gap is axial, and the linearly moving member is so constructed that axial current is prevented. This is achieved in flat-type machines as shown in Fig. 3 (15973/59) by winding the stators 10, 11 so that like poles are opposite and the working flux passes axially through the moving member 12 instead of across the gap. The conductors 13 on the moving member are only connected in pairs, e.g. A and B, so that the moving member may take the form shown in Fig. 4 (15973/59), in which a core 15 is surrounded by alternate rings 16, 17 of copper and iron respectively. Alternatively it may comprise a rectangular copper sleeve on an iron core, and this core may be stationary to provide a guide on which the coil-part slides. A better performance is attained if the sleeve is formed as a coil short-circuited on itself, or as shown in Fig. 4 (3076/60), several such coils 32, 33. The machine may be of tubular form, in which case the stator consists of coils wound on an insulating tube, the moving member being arranged as above. Return springs may be provided at each end.

Title: Improved method of and apparatus for cutting wired glass
IPC: C03B33/07
Filed: 1935-06-01
Abstract: 457,615. Cutting wired glass. PILKING- TON BROS., Ltd., 703, Tower Building, Water Street, Liverpool, and GASKELL, J., Stockswell, Hard Lane, St. Helens, both in Lancashire. June 1, 1935, No. 15979. [Class 56] A method of cutting wired glass consists in first cutting the glass and then shearing the wires by moving the cut edges of the glass relatively to one another in the direction of the cut and in the plane of the glass. Fig. 1 is a plan and Fig. 2 is a sectional elevation of a machine for cutting a continuouslymoving strip 1 of wired glass as it passes from a leer over a roller conveyer 2. The strip passes over three rollers 3 and a single roller 4 which are mounted on a truck 8 that runs along a short track 12 but is normally drawn towards the conveyer 2 by a weighted cable 48. The truck 8 carries a solenoid 14 which, when energized, forces a pad 15 downwards towards the rollers 3. The truck also carries two transverse screws 25, 31 on which are mounted shearing blocks 27, 28 respectively, that are adapted to engage the side edges of the strip 1. The screw 25 can be turned by a handwheel 26 to bring the block 27 just clear of one edge of the glass strip, while the screw 31 is rotated by a motor 35 to move the block 28 to or from the other edge of the glass. The block may also be moved by pneumatic or hydraulic means. Brackets on the truck support a transverse straight edge 46 above the glass strip, and also a snapping-bar 38 which is movable vertically, below the glass, by a pedal 42. In operation, the glass sheet 1 travels over the rollers 3, 4 until the solenoid is energized by the advancing edge of the glass strip striking a starting switch. The solenoid then forces the pad 15 downwards, and the pressure against the glass locks the truck 8 to the moving strip so that it is carried along the track 12. An operative scores the glass by moving a cutter along the straight edge 46, and then pressed the pedal 42 to raise the bar 38 and snap the glass. The motor 35 is set in operation to move the shearing-block 28 against the edge of the glass, so that one of the cut edges is moved relatively to the other between the blocks 27, 28 until the embedded wires are sheared. The operative then reverses the motor to restore the block 28 to its outer position, and the sheared-off length of glass is carried away by a roller conveyer 5. The truck continues to move along the track 12 until one wheel, 11, opens a switch 50, when the cable 48 draws the truck back to the position shown. The shearing-device can be mounted on a stationary frame when used for cutting a stationary glass sheet.

As the belt moves round these projections engage guides 27 which cause the rods to be advanced into the flax and afterwards retracted. While in their extended position the rods move upwardly as the belt reaches an inclined portion of its travel, thus straightening the flax. The front end of the machine is supported on two pivoted runners 16. The flax is gripped between the belt 36 and the wheel 35, pulled in an inclined direction, and deposited at the rear of the machine.
