Title: Improvements in processes of and devices for sizing textile threads and the like on beams or spools
IPC: D06B3/04
Filed: 1930-06-12
Abstract: <PICT:0363334/IV/1> Textile threads are sized on beams or spools by forcing sizing solution through the material in a digester under a pressure of from 1 to 4 atmospheres by compressed air, excess solution being removed from the threads and digester by compressed air acting in the opposite direction.  Sizing solution from a vat 1 is drawn into a bell-shaped tank 4 communicating by a pipe 16 and cock 21 with a vacuum pipe 19 and when the tank is full the cock 21 is closed and a cock 20 opened to connect the tank to a pipe 18 leading from a source of compressed air, communication with the vat 1 being closed.  Through a cock 11 and pipe 7, the tank is put into communication with a perforated core 27 about which the thread is wound and the solution is forced through the material into a digester 6, which encloses the material, until an overflow pipe 22 shows that the digester is full.  After treatment, the digester is put into communication, through a cock 23 and pipe 22, with the pipe 18 and a cock 15, on a byepass 14 between the digester and pipe 7, is opened to allow the compressed air to drive the solution out of the digester along the pipe 7 and up a pipe 8 into the tank 4.  When the digester is empty, the cock 15 is closed, and the compressed air drives surplus liquid from the material through the core 27.  A cock 17 on the pipe 16 is opened to allow air to escape to the atmosphere.

Title: Internal combustion engine valve gear using hydraulic tappets
IPC: F01L1/245
Filed: 1964-05-01
Abstract: 998,350. I.C. engine valve gear. JOHNSON PRODUCTS Inc. May 1, 1964 [May 16, 1963], No. 18206/64. Heading F1B. [Also in Division F2] In an I.C. engine having a hydraulic tappet in which a tubular push rod 20 seats on the bottom wall of a plunger 45 sliding in a tappet body 41, oil supplied to the push rod from rocker arm 11 passes through opening 48 and check valve 49 to compression chamber 46 and the push rod bore serves as an oil reservoir. Pressurized oil in rocker shaft 12 passes through orifice 15, passage 16 and opening 22 into the push rod bore 21. When the pressure in bore 21 exceeds that in chamber 46 e.g. when the valve 1 is closed, valve 49 opens to admit oil to chamber 46, thus taking up clearance. Air present in the oil is bled through opening 17 and between rocker shaft 12 and rocker arm 11 to passage 18, oil escaping from passage 18 lubricates the engaging surface. In a modification, the rocker arm passage 16 is offset from the opening 22 so that in the valve closed position air in push rod 20 bleeds through opening 22 and a groove in seating 19 whilst in the valve open position the rocker arm passage coincides with opening 22. An air bleed hole may be provided in the upper part of the push rod. In a further modification the push rod has a funnel-shaped end, oil being fed by gravity from a passage in the rocker arm which cyclically coincides with a passage in the rocker arm shaft to the funnel-shaped end.

Title: Improvements in or relating to electronic counting devices
IPC: H03K29/00
Filed: 1952-07-19
Abstract: 721,058. Multi-stable state circuits. BRANSON, L. C. July 2, 1953 (July 19,1952], No. 18285/52. Class 40 (6). [Also in Group XIX] In an electronic counter of the type employing rnulti-cathode gas-discharge tubes, carry signals are derived from a selected transfer electrode or electrodes situated between two of the storage cathodes of a tube. The transfer electrodes situated between the " 9 " and " 0 " storage cathodes have separate connections so that each multi-cathode tube has seven terminals as follows: (i) anode 18, Fig. 3; (ii) " 0 " storage cathode 19; (iii) " 1 to 9 " grouped storage cathodes 20; (iv) the transfer electrode 21 of a first group which is situated between the " 9 " and " 0 " storage cathodes; (v) the remaining nine transfer electrodes of the first group 22; (vi) the transfer electrode 23 of a second group which is situated between the " 9 " and " 0 " storage cathodes, and (vii) the. remaining nine transfer electrodes of the second group 24. In a first embodiment each of the two transfer electrodes 21, 23 which lie between the " 9 " and " 0 " storage cathodes are connected to the remaining transfer electrodes of the group 22, 24 to which they belong through the primary winding 38 of a transformer, the secondary windings of the transformers being connected between a source of bias 42 and the input terminals 22, 24 of the next higher tube stage. The order in which pairs of pulses are applied to terminals 22, 24 determines whether the discharge steps round in the positive or negative direction. When the discharge steps across the transfer electrodes 21 and 23 corresponding pulses are transmitted to the input terminals 22, 24 of the next stage, and so on. In another embodiment, Fig. 6 (not shown), the carry pulses developed across the secondary windings of the transformers are amplified before application to the next stage of the counter. In a further embodiment, Fig. 7, differential amplifiers are arranged between the counter stages. The arrangement for one group of transfer electrodes only is shown. Negative voltage pulses at the input 58 are applied also through a capacitor 67 to the R.H. grid 69 of a double-triode amplifier, and through a resistor 60 and capacitor 68 to the L.H. grid 70. When the discharge arrives at the transfer electrode 62 the current flow increases the voltage at the point 61 so as to cause the L.H. half of the double triode to conduct more heavily, whereby a negative pulse at its anode is passed on to the input of the next tube stage. In yet another embodiment, Fig. 8 (not shown), direct coupling is used between stages, and the counter may be operated by sine-wave inputs.
