Abstract: 504,850. Gas compressors ; machinery supports. TRIGGS, W. W. (Armaturen & Maschinenfabrik Akt.-Ges.) Jan. 12, 1938. No. 1008. [Class 8 (i)] [Also in Group XXIV] A compressor for chlorine gas which may comprise one or more stages or cylinders and be single or double-acting is suspended from a ceiling or supporting frame so.as to be accessible from all sides. The stage 1 and its supporting pillars 3 may be of concrete, wood, or iron ; the crank-casing 4 and its driving pulley 5 are located above the stage and the single or multiple cylinders 6, 6a, 7 below. Fig. 4 shows pair of double-acting suspended cylinders with connections for parallel or series working. In series working, the gas is drawn from the pipe 8 through pipes 27, 25 to the two first-stage cylinder spaces II, and discharged into an acid separator 13 from which a pipe 11 and branch pipe 21 supply the second-stages I, the gas .being discharged through the acid separator 10 and pipe 15. When working in parallel, the valve 12 is closed and a valve 22 opened, and the discharge from the separators is made through a common pipe 17.

Title: Process for the treatment of jute in order to obtain a fibre similar to wool
IPC: D01C1/00
Filed: 1929-01-15
Abstract: 309,021. Textiles (New Process), Ltd., (Assignees of Viallet, J.). April 3, 1928, [Convention date]. Retting.-In a process for treating jute, either unwoven or in fabric form, and particularly waste jute fabric such as old sacks or coverings, to produce a fibre resembling wool, the material is treated in a bath containing a small quantity of an enzyme such as diastase or diastafor and in addition a substance such as soda, the object of which is to attack and remove the starch and glue covering the threads of the fabric. The material is next treated in a culture medium formed in a bath containing a bundle of jute in its natural state from India soaked in a solution of potassium phosphate. This medium attacks the pectins in the waste jute fabric and the treatment extends for about 24 hours. The waste fabric is next stacked and heated to a temperature of 30‹ C. and fermented. The fermented mass is then unravelled in a damp state yielding long, supple, clean fibres suitable for mercerizing and bleaching.

Title: Improvements in or relating to rotary washing machines
IPC: D06F39/08
Filed: 1957-02-16
Abstract: The dry-cleaning machine of the parent Specification is modified so that accumulation of liquor in the machine from a continuous supply is eliminated for any selected height of "dip" by suitably adjusting the setting of the overflow pipe 13 (Fig. 2), in the external tank 12 of the machine by means of a rod 14 linked at 15 to a lever 16.  In one embodiment the invention is applied to an end-loading machine described in Specification 688,076.  The drain valve 20 (Fig. 6), of the machine has an additional "reclaim" setting, whereby spent liquor from the tank 12 is diverted for reclamation, e.g. to recover rinsing liquor for re-use during the "wash" stage, or to recover heat from spent "wash" liquor.  The lockable valve 20 has a rotary plug 21 with a throughpassage 22, used alone for the "open" setting in draining, and a passage 23, used therewith in the "reclaim" setting, the plug 21 having a handle 20a which may co-operate with an indicator plate 25.  In a different end-loading machine (Fig. 7), a longitudinal row of ports in the casing wall admit liquor to a duct-like external chamber 26 connected to the upper part of the tank 12.  The liquid enters the machine through a valve 30, and with several machines such valves may connect with a ring main for circulated heated liquid. <PICT:0825959/III/1> <PICT:0825959/III/2> <PICT:0825959/III/3>ALSO:In a rotary washing-machine as described and claimed in the parent Specification, accumulation of liquor in the machine from a continuous supply of detergent solution is eliminated, for any selected height of "dip," by suitably adjusting the setting of the overflow pipe 13 in the external tank 12 of the machine by means of a rod 14 linked at 15 to a lever 16.  In one embodiment the invention is applied to an end-loading washing machine described in Specification 688,076.  The drain valve 20 of the machine has an additional, i.e. a third, optional position (Fig. 6), a "reclaim" setting, so that spent liquor from the tank 12 is diverted for reclamation.  Thus, rinsing liquor may be re-used during the "wash" stage, or the sensible heat from spent "wash" liquor may be recovered.  The lockable valve 20 has a rotary plug 21 with a through-passage 22, used alone for the "open" setting in draining, and a passage 23, used therewith in the "reclaim" setting, the plug 21 having a handle 20a which may p  cooperate with an indicator plate 25.

Abstract: 111,584. Evans, J. Feb. 1, 1917. Swifts.-In an apparatus for greasing wire ropes or ropes or lines of other materials, the receiving-drum E may be slightly tapered and is removable from its bearings. One of the flanges of the drum is loose, so that the coil of rope &c. may be slid off the drum. The coil is wound on strips of wood or metal Q laid round the drum. The spaces between the strips form guide channels for the binding wire or cord. If a cylindrical drum be used, the strips Q may be tapered. The drum may be supported on standards B, C secured to the bank or otherwise.

Title: Improvements in or relating to acoustic frequency electrical circuit arrangements
Filed: 1935-01-17
Abstract: 450,468. Optical sound recording apparatus and processes. ROUND, H. J., Westfield, Muswell Hill, London. Jan. 17, 1935, No. 1654. [Class 40 (ii)] [See also Group XXXIX] A method of obtaining envelope waves from a band of acoustic frequency waves, more particularly for use in sound film recording, consists in subdividing said band into a plurality of sub-bands, independently rectifying said sub-bands and smoothing the rectified resultants, the smoothing of the rectified sub-bands being such that each smoothed rectified resultant is a sub-band of envelopes, said sub-bands substantially not overlapping and then adding the smoothed rectified resultants to obtain the required envelope waves. As shown, the audio frequency band from which the envelope waves are to be derived is fed in through a transformer A whose secondary feeds into two filters LP, HP by means of which the whole audio band is divided into two sub-bands. The low pass filter LP is arranged to pass the band extending from, say, 50 to 500 cycles, whilst the high pass filter passes the band extending from, say, 500 cycles to 10,000 cycles. The filter LP feeds through a transformer T1 into a rectifying and smoothing circuit D1, C1, R1, the smoothing in which is accomplished to such an extent that the highest frequencies in the smoothed output set up across R1 are not above a desired low frequency, e.g. 20 cycles. The filter HP similarly feeds through a transformer T2 into a rectifying and smoothing circuit D2, C2, R2 so that in the resultant smoothed envelopes set up across R2 frequencies up to about 300 to 500 cycles appear. Resistances R1, R2 are connected in series so that the series resultant set up between the output terminals O1 02 will be a substantially complete series of envelopes corresponding closely to the original sound waves.

Filed: 1952-01-22
Abstract: 728,393. Sawtooth generating and integrating circuits. GENERAL ELECTRIC CO., Ltd. Jan. 22, 1953 [Jan. 22, 1952], No. 1788/52. Class 40 (6). In a " Miller " integrating circuit employing a capacitor 3 between anode and grid of valve 1, a resistor 24 is connected between grid and cathode of a cathode follower 16 and is arranged effectively across part of the anode load to improve the linearity. When employed to generate a sawtooth, a negative pulse applied to the suppressor causes capacitor 3 to recharge over resistors 6, 7 and diode 25. During the succeeding anode run-down period, the effective impedance across the resistor 6 is increased due to the cathode follower action of the valve 16, the stage gain being thereby increased and hence the linearity. The recharge period may be decreased by cutting off the valve 16 (Fig. 2, not shown) at the suppressor grid with the synchronizing pulse so that the effective impedance falls.
