Title: Improvements in the laundering of white textile articles
IPC: C11D3/42
Filed: 1944-03-01
Abstract: In the laundering of cellulosic textile articles of the class requiring frequent laundering, wherein the articles are washed by customary methods, they are thereafter rinsed in an aqueous bath containing a very small proportion of a substantive blue fluorescent substance.  Advantageously, the aqueous bath contains not more than 0.05 per cent and suitably between 0.01 per cent and 0.001 per cent of the blue fluorescent substance calculated on the weight of the articles to be rinsed.  The blue fluorescent substance is preferably one showing an absorption maximum at about 3400 to 3700 Angstrom and it may be used in any of the rinses following the wash.  Specified substances are a di-benzoylaminostilbene-sulphonic acid or a nuclear substitution derivative thereof or a salt of these acids, e.g. a 4 : 41-di-benzoylaminostilbene-2 : 21-disulphonic acid or a nuclear substitution derivative thereof or a salt of these acids; 4 : 41-di-p-aminobenzoylamino-stilbene-2 : 21-disulphonic acid or a salt thereof; sodium 4 : 41-di-p-methylbenzoylamino-stilbene-2 : 21-disulphonate; the corresponding 3 : 31-disulphonates and 2 : 21-6 : 61-tetrasulphonates; the symmetrical urea derived from sodium 4-amino-41 - benzoylaminostilbene - 2 : 21 - disulphonate; dibenzyl derivatives such as sodium 4 : 41-dibenzoyl-aminodibenzyl - 2 : 21 - disulphonate; benzidine derivatives such as sodium-dibenzoylbenzidine - 3 : 31 - dicarboxylate; and the symmetrical urea derived from sodium-4-amino-41-benzoylaminostilbene - 2 : 21 - disulphonate.  In an example, a mixed batch of towels, tablecloths, pillow-cases and napkins is washed with soap in the usual way, rinsed twice in clean water and then given a final rinse in water containing in three tests respectively 0.0005, 0.001 and 0.004 per cent (calculated upon the water=7 gallons) of the sodium salt of 4 : 41-di-p-aminobenzoylaminostilbene-2 : 21 - disulphonic acid.

Inventor: SMITH ALFRED WILLIAM
IPC: B24D15/08
Filed: 1916-03-21
Abstract: 104,562. Smith, A. W. March 21, 1916. Stropping-apparatus for razors comprises a single rotatable stropping-drum 12 of a length substantially equal to that of the blade to be treated, a driving-pulley 22 on the drum, a substantially smaller pulley on each of one or more rotatable bladeholders, and a reciprocatable band or cord 24 engaged with the pulleys to rotate them. As shown in Fig. 1, the blades 18 are in contact with the drum in the positions they occupy when stropping is effected by a pull on the left-hand end of the cord, which is so wound that the drum always turns in a direction away from the blade edges under treatment. If then the right-hand end of the cord is pulled, the pulleys 25 are turned and the blades carried round quickly to bring opposite edges against the drum, which is then also rotated in the opposite direction. The drum is mounted on a fixed spindle 10 and retained by a cross-bar or frame member 7, which is secured by nuts 8, 9 so that the bar and the drum can be readily removed. For imparting a slight endlong movement to the drum during its rotation, it is mounted by a screw-thread upon the fixed spindle, projections 29 formed upon the drum and pulley or washers mounted on the spindle being provided to prevent jamming of the end face of the drum or of the pulley against the cross-bar 7 or the frame 1. Each blade-holder comprises a plate rotatably mounted on a fixed spindle and carrying a pulley 25, the blade being held between this plate and a slide 19 which is introduced under and retained in position by, end clips on the plate. An extension 20 serves as a finger-grip for withdrawing the slide. Several drums with a variety of stropping-surfaces may be supplied with the machine.

Title: Improvements in or relating to sound recording
IPC: G11B7/00
Filed: 1939-02-13
Abstract: 525,052. Optical sound recording. RADIO CORPORATION OF AMERICA. Feb. 13, 1939, No. 4683. Convention date, Feb. 12, 1938. [Class 40 (ii)] Relates to sound recording systems in which a plurality of vibrated light beams are projected on a film, and consists mainly in the provision of a controlling device which gradually eliminates one beam and simultaneously gradually varies the amplitude of vibration of the other beam or beams. In the form shown in Fig. 1, a double-hump record is produced on a film 17 in a known way by means of a lamp 5, a mask 8 with ground-noise shutters 9, a galvanometer 12, a slit 15, and accessory lenses. The galvanometer 12 is fed from an amplifier 34 itself fed from a master amplifier 35 supplied in known manner from pick-ups 36, 37, 38 through amplifiers 39, 40, 41, potentiometer mixers 43, 44, 45 and volume control potentiometer 46. The output of the amplifier 35 is also connected in generally knownmanner to a loud speaker 48 and a measuring instrument 51 for monitoring purposes, the loud speaker being relied upon for the adjustment of the mixers 43, 44, 45, and the meter 51 for the adjustment of the volume control 46. Now, according to the invention, (1) a wedgeshaped shutter 20 is provided at the slit 15 and is operated by a solenoid 21 controlled by a switch 32 ; (2) a variable attenuation network in the form of resistances 69 is provided between the amplifiers 34 and 35 and is adjusted by a solenoid 63 controlled by the switch 32 ; (3) a double-pole switch 60 is coupled to the switch 32 and is adapted to connect the meter 51 directly to the amplifier 35 when the electromagnets 21, 63 are out of action, and to interpose an attenuation pad 62 when the electromagnets are switched on ; (4) a signal lamp 28 is provided to indicate that the solenoids are switched on, and another lamp 29 to indicate that the solenoids are off; and (5) timing devices such as dash-pots 22, 67 are provided to make the solenoids perform their stroke. in substantially the same time interval. The operation of the system will be explained with reference to the positive record shown in Fig. 2. With the solenoids energized and no sound coming from the pick-up, the so-called "bias-lines" 72, 73 are obtained. Sound of large amplitude then yield traces 77, 78. If sound amplitude falls to level 81, 82 where ground-noise becomes considerable, the solenoids are switched off, so that the shutter 20 cuts off one beam and simultaneously the resistances 69 are cut off thereby correspondingly increasing the volume supplied to the galvanometer. The change takes place from a-c to b-d on the positive record, after which the record becomes a single one e with equivalent volume but reduced ground-noise. If volume again rises, reversion is made to the double beam recording 77, 78.
