IPC: A01J11/16
Filed: 1948-12-14
Abstract: <PICT:0656915/III/1> <PICT:0656915/III/2> In a homogenizing device where liquid is forced under pressure between two co-operating blocks separated by a narrow aperture, two co-operating pairs of frusto-conical surfaces of different inclination provide two successive stages of homogenization and one expansion chamber is formed by a recess cut at the junction of the surfaces.  For any lateral displacement of the blocks from each other, the pair of surfaces of smaller inclination then have a greater separation and to this pair it is preferred to feed the liquid first.  In Fig. 4, the pairs of surfaces 20, 26, 21, 25 on blocks 15, 16, are separated by an expansion recess 27.  Liquid passes up the central passage 28 and leaves the second pair of surfaces via channels 30 formed in the upper block.  An adjustable spring 11 is provided to force the blocks together.

Title: Electronic data storage device
IPC: G11C11/30
Filed: 1954-11-15
Abstract: 768,110. Electric digital data storage apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. Nov. 15, 1954 [Nov. 18, 1953], No. 32991/54. Class 106 (1). Apparatus for dynamic storage of electric pulses comprises a one-shot multivibrator which, upon receipt of the initial pulse of a train of pulses supplied thereto, commences repeated cyclical operation by changing from its normal state to an alternative state for a period corresponding to a pre-selected number of pulses, and, on receipt of the next pulse following its return to the normal state, commences a new cycle and simultaneously emits an output pulse. A train of clock pulses A, Fig. 1, is supplied to the cathode of a valve T1, Fig. 6, which is prevented from conducting'by a: negative bias on its grid until a positive potential appears at a terminal G at a time representing a decimal digit (" 5 " in the example given) in a time cycle of 16 points. From then on a series of negative pulses B are produced at the anode 2, the first of these being fed via a diode 4 and capacitor 9 to the grid 10. of a one-shot multivibrator T2, driving it into the L.H. sideconducting state. The voltage of the L.H. anode 8 falls to 80 while the multivibrator is in this state, and therefore subsequent B pulses, which do not fall below 100 volts, are blocked by the diode 4. The multivibrator can be arranged to return to its normal state after just less than sixteen points of the cycle, whereupon the next B pulse will drive it back to the alternative state for a further cycle. To achieve greater precision a second one-shot multivibrator T3 is arranged for restoration after nearly a complete cycle, while the multivibrator T2 is now arranged to return after 4 points. Although the multivibrator T3 would normally be restored before a full cycle has been completed, it cannot be returned again to its alternative state until the shorter-cycle multivibrator T2 has restored. At the commencement of the new cycle an output pulse is developed at the cathode 27 of tube T4,

In a reservoir pen the feedbar is formed with a flow conduit extending from a point underlying the nib to the ink reservoir, such conduit including a straight portion underlying the nib and a circuitous portion around the wall of the feed-bar, the latter portion having one or more capillary channels in its bottom surface for the downflow of ink and an overlying open portion for the ingress of air. In one form, Figs. 2, 4, the feed-bar has at its inner end a helical capillary groove 24 which connects with a longitudinal groove 23 underlying the nib 19. Fins 25 forming capillary channels are provided in the base of the groove 24. The length of the helical groove 24 is about the same as that of the straight groove 23. In a modification, Fig. 8, the upper parts 28 of the walls of the groove 24 are flared outwardly from a bottom capillary channel, and the fins 25 are omitted. The straight groove 23 beneath the nib may be similarly shaped. As shown in Fig. 11, the helical groove 17a, with one capillary bottom channel, is connected to the longitudinal groove by a diagonal bore 31 whereby, during filling of the pen by expanding the sac 15 in the normal way, only the nib and lower end of the feed-bar need be immersed in the ink. The bore 31 may be cylindrical with a tube of elliptical cross-section therein, so that the space outside the tube constitutes a capillary passage for the ink and the space inside forms an air passage. According to a modification, the bore 31 is triangular with narrow passages at the corners to provide capillary ink channels ; the air passes along the centre of the bore. The helix 34, Fig. 11, by which the groove 17a is formed has diametrically-opposite portions which are perpendicular to the pen axis to facilitate moulding of the feed-bar in a two-part mould.
