Title: Desk set with hinged pen cup
IPC: B43M99/00
Filed: 1936-09-02
Abstract: 481,111. Pen-stands. DEHN, F. B. (Parker Pen Co.) Sept. 2, 1936, No. 24086. [Class 146 (iii)] In a desk set of the type in which a receptacle for the ink end of a fountain pen is mounted on a base, a member connected to the receptacle is hinged to the base, and the hinge connection has provision for limiting the movement of the receptacle from a position in which it is tilted very slightly above the horizontal to a position less than the vertical, so that, in the first position the ink from the pen will flow with only a minimum of pressure towards the writing point, and in the second position insertion of the pen is facilitated. The receptacle 11 is provided with two downwardly projecting lugs 19, pivoted within a recess 21 in a standard 16. The standard is mounted, as described in Specification 387,442, by means of a split sleeve 15 rotatably received within a sleeve 13 set in a base 10. The recess 21 is provided with walls 24 and 23 set respectively at angles of approximately 5‹ and 45‹ to the vertical, so as to limit the movement of the receptacle 11 between positions of 5‹ and 45‹ to the horizontal. The pen 12 is provided with a threaded or rounded enlargement 38 which is gripped by bowed spring fingers 43 of a collar 39, secured to the receptacle by a screwed cap 44. Alternate straight legs on the collar 39 press against a washer 46, which forms the outer limit to the movement of a sliding cup 28. The cup 28 is guided in a recess in a weight 26 and is pressed outwards by a spring 30 so that a soft-rubber seat 35 forms a seal with the end of the pen. When the pen is removed the weight 26 carries the receptacle to the more upright position ; when the pen inserted its weight brings the receptacle to the nearly horizontal position. The movement of the receptacle in both directions may be braked by a piston 56, Fig. 5, linked at 54 to the receptacle and moving in a bore 57 in the stand 53. An air passage 58 is provided and may be closed by a ball valve against too rapid escape of air. Alternatively the receptacle may be carried by a sector 65, Fig. 7, gearing with a train of wheels 69, 73 mounted between the hollow walls of the stand 62, the friction of the wheels having a braking effect. In both these modifications the motion of the receptacle is limited by its engagement with two faces on the outside of the stand.

Inventor: PEAT JOHN DEWAR
IPC: H01Q7/00
Filed: 1947-09-01
Abstract: 675,164. Aerials. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. March 25, 1948 [Sept. 1, 1947], No. 24105/47. Class 40 (vii). An aerial system having a substantially circular radiation pattern comprises a plurality of capacity loaded loop aerials side by side in juxta-position and angularly displaced with respect to one another in the planes in which they lie. It is stated that with a known capacity loaded loop such as that of Fig. 1, the current in the radiators drops to 0.924 of its maximum value at each end of the radiators causing non-uniformity in the field pattern particularly close to the loop. If, however, a second loop angularly displaced by 45 degrees be placed side by side with the first and both energized the resultant pattern is more nearly circular, a larger number of aerials with regularly spaced angular relationships will give still better omnidirectional results. A three-loop system, Fig. 4, comprises three loop sections 9, 10 and 11, with oppositely dispersed gaps 12 and 15 cut diagonally to provide angular displacement between the loops. Capacity loading is introduced at 13 and 14. In a development of this arrangement a large number of turns of wire are wound on a cylindrical former to provide a corresponding number of loops, inclined gaps are cut across the loops for the connection of the feeders and capacity loading elements in the form of triangular plates, Figs. 5 and 6 (not shown).

Abstract: 360,985. :Embroidery and running- stitch machines. JENNINGS, H. W. K., 51, Chancery Lane, London.-(Claes & Flentje Ges. ; M³lhausen, Thuringia, Germany.) Aug. 16, 1930, No. 24616. [Class 112.] Threads or ribbons are inserted into fabric by dividing the cross threads into groups in front of the needle and moving the groups alternately up and down so that when the fabric is fed forwards, the threads are positioned above or below the needle. Fig. 12 shows the needle a carrying the thread or ribbon e<1> and clamped to the presser foot c at c<2>. The blade g<1> descends to group two threads in front of the needle and the member f<2> rises to displace tl ese threads above the needle point. The blade g<1> then moves towards the needle, placing the threads above the needle. The blade g<2> then ascends to group three cross threads in front of the needle point and the member f<1> descends to depress these threads below the needle point. As the blade g<2> moves to the needle, these threads are placed below the needle. The parts are returned to original positic n as the complementary parts are operating. The fabric is fed forwards as the members g<1>, g<2> move forwards to avoid strain on the threads. Cumulative inaccuracies due to incorrect adjustment of the blades are automatically compensated for periodically by feeler combs m<1>, m<2> mounted to slide freely in the feed dog b and having a projection m<3> engaging a flat in the pivoted pawl n. These feelers are displaced along the feed dog bit by bit as the errors total up, until they release the pawl n to engage the teeth b<1> earlier than before, so causing a difference in the length of the feed stroke and a corresponding correction for errors.

Title: Improvements in coil ignition systems of internal combustion engines
Filed: 1939-08-28
Abstract: 532,362. Ignition systems. GENERAL MOTORS CORPORATION. Aug. 28, 1939, Nos, 24668 and 24669. Convention dates, Aug. 31, 1938, and May 29, 1939. Drawings to Specification. [Class 7 (iv)] Compensation for the transfer of material to the negative contact of the primary circuit interrupter, due to electronic flow from the instant of break, is obtained by subjecting the contacts to a voltage additional to the primary voltage and which is the sum of the primary induced voltage and a transient voltage derived from high-frequency oscillation which occurs when the secondary circuit discharges. Arcs established by the consequent flow of positive ions result in transfer of material to the positive contact. Such compensation may be effected (1) by increasing the capacity coupling between the low and high tension leads from the coil to the interrupter and to the distributer, respectively ; as by taping them together and separating them from the engine and earth ; (2) by a capacity coupling of the leads from the distributer to some or all of the sparking plugs with the insulated terminal of the interrupter, for which the leads may be bundled together ; (3) by increasing the length, and consequently the inductance, of the lead to the condenser bridging the interrupter contacts ; (4) by reducing radio-interfering suppressors. Compensation, it is stated, is required to a greater degree in 6-volt ignition apparatus than in apparatus taking 12-volts ; in the latter case the foregoing correcting factors may even have to be reversed to prevent building up of the positive contact.
