Patent GB-186334-A (GB)
Title: Improvements in fountain pens
IPC: B43K5/06
Filed: 1922-09-15
Abstract: 186,334. Mitchell, O. Sept. 23, 1921, [Convention date]. Reservoir pens.-A fountain pen is provided with a cupshaped member B mounted to reciprocate in the rear end of the barrel 1, and a disc C frictionally engaging the inner walls of the cup and adapted to be moved thereby on a tube A to open and close air passages from one side of the disc to the ot,her and to open and close a passage a<2> communicating with the interior of the tube A. The tube communicates at its forward end with a passage through the feed-bar 2. The plug C is limited in its movement on the tube by stops a, a<1> and serves to prevent the complete withdrawal of the cup from the barrel 1 by engaging with stops e, which are so arranged that they arrest the movement of the cup when slots E in the walls thereof establish communication between the chambers above and below the plug. To fill the pen, the forward end is immersed in ink and the cup B is drawn out by means of the abutment b, so that the plug C is moved along the tube A to close the opening a<2>. The plug is then arrested by the stop a, and the cup, during its further withdrawal, causes the air behind the plug to be rarefied, so that when arrested by the engagement of the plug and stops e, ink is drawn into the barrel through the feed-bar openings 3. In pushing in the cup, the plug is carried down the tube, to open the passage a<2>, until arrested by the stop a'. Further movement of the cup cuts off communication through the slots E and the air compressed behind the plug escapes through the passage a<2> and tube A.

Title: Method for embroidering in two colours with a single needle
IPC: D05B93/00
Filed: 1933-09-11
Abstract: 413,142. Sewing and embroidery. KLEINERT, C., Friedrichsthal, Niederbarnim, Germany. Sept. 11, 1933, No. 25095. [Class 112.] A method for continuously embroidering in two colours by means of a single needle consists in threading the needle with two different coloured threads, passing the threads through the fabric from below at the point 1, whereupon one thread 2 is laid in a straight line in the upper surface of the fabric and the other thread 3 is spread at an angle. The needle is then passed through the fabric from above at 4, moved along the back and passed through at 5, so holding the threads 2 and 3 in position. The process is repeated to produce the two-coloured pattern shown. Other patterns may be produced. Needles.-To avoid the difficulty of threading a needle with two thick threads, needles with two eyes at right angles to each other as shown in Fig. 5, are provided.

Patent GB-407053-A (GB)
Title: Improvements in or relating to machines for winding wire, thread or the like from one reel, spool, or bobbin to another
IPC: B65H54/42
Filed: 1932-09-09
Abstract: 407,053. Winding yarns etc.; creels. RICHARDS, S. H., Highlands, Wood End Road, Harpenden, Hertfordshire, and LLOYD, H. J., Thorpe Lodge, Thorpe-le-Soken, Essex. Sept. 9, 1932, No. 25184. [Class 120 (ii).] In a machine for winding wire, thread, or the like of low tensile strength from one bobbin to another, both bobbins are frictionally driven from a common drive member in such a manner that the speed of winding remains constant. Means are provided for adjusting the pressure on the frictional driving member, for compensating irregularities in rate of feed or take-up, and for starting the machine gradually from rest. A friction wheel 2 having a rim of rubber or the like drives the supply bobbin 7 and the take-up bobbin 13 by contact with the windings thereof. The thread or wire is led over a counterbalanced tensioning lever 19. The bobbins are mounted in cradles 9, 9<a> ; 14, 14<a> pivoted at 10 and 15 to the lever 11, 11<a> pivoted at 12, which latter allows the bobbins to be removed from driving contact with the wheel 2. The pressure exerted by each bobbin on the driving wheel is adjusted by moving a weight 16 along a bar 17 held in the cradle 9<a> or 14<a> depending from the bobbin support. The machine is started gradually from rest by slowly moving the lever 23, 24 so as to tension the driving belt 4. The driving wheel 5 also drives the cam 26 which reciprocates the traverse arm 25.

Title: Improvements in or relating to load sensitive governors
Inventor: ADLER HERMAN G
IPC: F02D9/00
Filed: 1955-09-01
Abstract: 810,463. Fluid-pressure servomotor-control systems. NOVI EQUIPMENT CO. Sept. 1, 1955, No. 25195/55. Class 135. A drop in the inlet manifold depression of an engine, due to increased loading, causes upward movement of a piston 34, Fig. 3, under the action of a spring 40 against atmospheric pressure acting on the rod end of the piston resulting in counterclockwise motion of a lever 80 about a pin 84 on the rod 10 of an hydraulicallylocked piston 18, and hence elevation of a piston-valve closure 46. Oil then flows from an inlet 70 through a passage 50 into the cylinder above the piston 18 which is thus lowered to adjust the spring of a centrifugal governor connected to the rod 10; oil from beneath the piston 18 is exhausted via passages 54, 56, 74 and 72, passage 74 having an adjustable needle valve 76 therein. This translation of the piston 18 also acts through the lever 80 to restore the closure 46 to the central position shown. The reverse process occurs upon a load decrease, the exhaust oil flowing to the passage 74 by passage 50 and an axial duct 58 in the closure 46. In a modification, the inlet manifold opens into a bellows 180, Fig. 14, in a body 104, the interior of which is at atmospheric pressure, so that a decreased inlet depression, for example, causes rightward movement of the bellows under the influence of adjustable springs 202, 204, whereupon a piston-valve closure 172 connected to a shaft 210 actuated by the bellows is similarly moved by its lever 278 to admit oil from the engine lubricating system into the right-hand end of a cylinder 152 resulting in leftward travel of a normally hydraulicallylocked piston 154, oil is exhausted from the other end of the cylinder 152, under the control of the closure 172, into the body 104. This movement of the piston 154 restores the closure 172 to its original position as well as causing rotation of a sector 270 geared to the piston and keyed to a lever 250, Fig. 7, having a bolt 258 threaded therein which receives an adjustable element 262 to which is secured one end of the governor spring 144; the other end of the latter is attached to the governor lever 132 connected to the engine throttle so that movement of the piston 154 adjusts the spring tension. The spring 144 sets up a force opposing the rightward movement of a dished plate 118, Fig. 9, which would result from outward travel of governor balls 120. The supply of oil to the closure 172, Fig. 14, is determined by an adjustable needle valve so that instantaneous fluctuations in the inlet depression do not influence the governor and adjustment of the spring 144 is subject to a time delay. The shaft 210 assumes a definite position for each value of depression; a lever 230 is provided to enable the shaft 210 to be clamped to prevent longitudinal movement thereof in respect of variations in manifold depression.

A glass container 11, the neck 15 of which is adapted to be sealed by an aluminium cap 12 having a flat top wall 33 and a depending skirt 34, is characterized in that the neck 15 is provided with an annular bead 18 having an outwardly and downwardly extending upper surface 21 and a lower surface 23 extending downwardly and inwardly from the upper surface 21 to include an acute angle therewith, the combined lengths of the surfaces 21, 23 not exceeding the length of the skirt 34. An auxiliary bead 26, spaced from the bead 18 by a surface 31, facilitates crimping of the skirt 34 to form a flange 35 which is held in the channel formed by the beads 18, 26. In this way the cap 12 is held in place against the pressure of the contents of the container. A gasket 41 is secured inside the cap to seal the container. In order to facilitate removal of the cap the top wall 33 is scored at 45, 46 and the skirt 34 is extended to form a tongue 47. The skirt 34 is cut away at 52 on both sides of the tongue 47 so that the tongue will not tear off.

Filed: 1971-04-19
Abstract: 1284256 Axial-flow fans; I C engine cooling systems FORD MOTOR CO Ltd 19 April 1971 [7 May 1970] 25502/71 Headings F1B and F1C An I C engine, especially for motor vehicles, has a cooling system comprising a radiator 1, Fig.2, and an electric-motor-driven fan 2. The electric motor 3 is connected to a control unit 4, Figs.2 and 3, located in the stream of air leaving the radiator. During normal engine temperatures the motor is energized through an electrical heating element 5 so as to rotate the fan at a relatively slow speed (e.g. 700 r.p.m.). However, at high engine temperatures, the additional heat causes bi-metallic switch 6 to close to thereby shunt the element 5 and cause an increase in motor speed (e.g. to 1400 r.p.m.). The motor is connected to the battery via the control unit and ignition switch so that the fan is operative when the ignition switch is closed. However, the motor may additionally be connected to the battery through the bi-metallic switch of the control unit, so that the fan continues to operate for a period after the engine has been stopped at high temperature, a diode preventing consequent energization of the ignition circuit and heating element. The system includes an air conditioning condenser 7.
