Patent GB-1516646-A (GB)
Title: Pipe organ
IPC: G10B3/22
Filed: 1975-05-15
Abstract: 1516646 Pipe organs: recording L W ELLEN 12 May 1976 [15 May 1975] 20570/75 Headings G5J and G5X A pipe organ wherein the pipes are controlled electrically in response to a decoded, Fig. 2, multiplexed signal 20, is generated by keying circuitry, Fig. 1. Information corresponding to the key states of each of three keyboards of a pipe organ is encoded by a respective multiplexer 12, and information corresponding to the states of organ stops and pedal keys by a fourth multiplexer 12. This multiplexed information is combined 11 and used to control the length of pulses of an oscillator 10. Each change of state of the pulse train thereby output along line 18 or via a radio link is detected 32 and the pulse lengths determined 43, i.e. whether a pulse corresponds to a "key on", a "key off", or a "synchronization pulse". Stop key information, transmitted at the beginning of a scan, is demultiplexed 49 and stored in a respective latch 50 for use with the note played signals. The latter are processed by a footage adder 56 wherein each signal is modified once for each footage of the organ to determine the addresses of the pipes corresponding to the played note, and the stop controls therefor, said adder being controlled 51 in response to an oscillator 57. The output from said adder, in response to footage information from controller 51 keyboard information from decoder 66, and stop ifnormation 71 is demultiplexed 74 in order to'set latches 76, 77, 78 for a selected pipe magnet 79. Additional functions may be provided. The use of a shift register 13 allows; interval coupling; extension of harmony to chords including tenths, for example; arpeggios; transposition of key (this may also be effected using a transposition adder 69); and interdepartmental duets. A keyboard coupler will also allow such duets, and additionally, by suitable modification, will allow separate parts of a single keyboard to enable different departments of the organ. A tape recorder can be provided to record a multiplexed signal, and to subsequently transmit it to the demultiplexers, possibly in such a manner as to allow modification of the replayed signal from the keyboards. The organ may also be modified to handle "second touch" on the keys. Sustain and a-tonal effects can also be handled.

Abstract: 1,189,165. Positioning machine parts. A. KELLER. 5 May, 1967 [13 May, 1966], No. 20947/67. Headings B3B and B3T. A device for the positioning of a linearly movable part such as a slide of a machine tool, e.g. a lathe, comprises a perforated rigid bar 22 mounted between a stationary part 6 and a movable part 9, the end of the bar being connected to the stationary-part in a mounting 7 and is longitudinally adjustable by a knob 14. The bar is also supported on the movable part of the machine by a valve unit 5 through which the bar passes during the movement of the part. Air is supplied to the valve unit 5 into a chamber 34 on one side of the bar and is discharged into a pair of receiving chambers 41, 41a on the other side of the bar when a bar perforation 24 passes the nozzle 40 of the chambers 41 and 41a. The nozzle 40 is divided by a diaphragm 42 so that as a perforation moves past the nozzle 40 air is at first admitted to chamber 41 then to chambers 41 and 41a. A pressure between the chambers is registered on a manometer gauge until the moving part is accurately positioned, when the pressure differential is zero. Indicating lights are actuated to denote the position of the movable part and its direction of movement until the equilibrium condition is reached. A counter mechanism may also be actuated to denote the slide position or the operation to be performed when in that position. The bar may be attached to either the fixed or movable part of the machine and likewise the valve unit.

Patent GB-358593-A (GB)
Title: Improvements relating to the treatment of fabrics containing organic derivatives of cellulose
IPC: D06M15/15
Filed: 1930-07-15
Abstract: A finishing treatment for textile materials made of or containing an organic ester or ether of cellulose comprises treatment with an albuminoid substance such as gelatin or casein and with formaldehyde or a compound yielding formaldehyde.  Thus the material may be steeped in a solution of gelatin and thereafter immersed in a solution of formaldehyde or subjected to the action of gaseous formaldehyde, but a finish more resistant to scouring is obtained when the albuminoid substance and the formaldehyde are applied in admixture.  Casein is applied in presence of alkali.  The treated material may be dried in a stretched condition, e.g. on a stenter, and then ironed, or may be dried in contact with a smooth surface, e.g. by subjecting it to a calendering operation.  In an example a fabric made of cellulose acetate yarn is steeped for 1 hour in a cold 1,4 per cent gelatin solution to every 100 parts of which have been added 5 parts or more of 45 per cent formaldehyde solution, and the material is then dried on a calender; fabric so treated is firm and has a soft, glossy appearance.  The process is applicable also to mixed materials containing organic derivatives of cellulose together with other fibres such as cotton, wool, silk, or regenerated cellulose.  The Provisional Specification refers also to keratin as a suitable albuminoid substance.

Title: Improvements in the purification of zinc solutions preparatory to recovery of zinc by electrolysis
IPC: C25C1/16
Filed: 1926-09-01
Abstract: 278,851. Rhodesia Broken Hill Development Co., Ltd., (Stevens, R. H., Norris, G. C., and Watson, TV. N.). Sept. 1, 1926. Zinc sulphate, xanthate, and salts in general.- Impurities, such as copper, cadmium, cobalt, nickel, mercury, antimony, and arsenic, are precipitated from zinc solutions, particularly from zinc sulphate solutions prior to electrolysis, by treating the solutions with a compound of a derivative of dithiocarbonic acid of the type MS, CS, OR, where M is a radicle of which the said compound is appreciably soluble in the zinc solution, and R is an organic radicle such as the radicle of an alcohol, for instance, an alkyl radicle. Alkali xanthates or zinc xanthates may be used for effecting the purification, the latter being obtained by double decomposition between an alkali xanthate and a soluble zinc salt. The solution may first be partially purified by neutralisation with a basic material, and soluble copper compound, if not already present, may be added to assist the precipitation of other impurities, such as those of nickel or cobalt. The impurity precipitate may be subjected to a reducing or oxidising roast to recover metals or metallic oxides respectively.
