Title: Digital switch with indicator
IPC: H03K17/96
Filed: 1976-06-16
Abstract: 1528668 Touch-responsive switching circuit MASTER SPECIALITIES CO 16 June 1976 [18 July 1975] 24949/76 Heading G1N [Also in Division G4] A digital indicating switch comprises in combination a switch housing 11 having a face 12 with a seven-segment digital indicator 26 with segments 19-25 and with conductive touch-responsive areas 27, 28 on the face. A capacitive, resistive or heat-sensitive touch-responsive switch 33 has an input connected to an external clock generator 34 and a second input connected to one or both areas 27, 28 and provides a train of output pulses synchronized with the clock generator whilst an area is touched. The switch 33 includes a spark gap 55 protecting transistor 46 from damage due to static charge on the operator. A monostable multi-vibrator 35 is triggered on each pulse and provides a corresponding pulse to a counter 36. Thus application of a finger for a time equal to or less than the cycle time of the multi-vibrator produces only a single increment of the counter output. The counter output passes to an optional latch circuit 39 and thence to a BCD-seven-segment decoder 41 driving the indicator 26. The first touch area and its touch switch may advance the counter and the second area and touch-switch may decrement the counter or clear it, Fig. 4 (not shown). Or the switches may have separate multivibrators connected respectively to an up-count and down-count input of the counter Fig. 5 (not shown).

Title: Process for the manufacture of aldehydes and ketones
IPC: B01J27/06
Filed: 1958-08-01
Abstract: A catalyst for use in the oxidation of olefines to aldehydes and ketones consists of an acid to neutral aqueous solution containing a compound of a metal of the platinum group and a salt of vanadium, chromium, manganese, iron, cobalt, nickel or copper. Sutiable platinum group metal compounds are halides, sulphates or acetates. Preferably the platinium metal compound is present in an amount of 2 to 20 gms/litre and a larger proportion of the other metal salt is present.  After separation of the products and unchanged olefine the residual catalyst solution is treated with oxygen and a compound of oxygen and nitrogen, e.g. nitric acid or oxides of nitrogen, and the regenerated catalyst solution may then be recycled.  Preferably the regeneration is carried out at a temperature of 50-170 DEG  C. and a pressure of 1-50 atm. gauge. Examples are given of the use of aqueous catalysts containing (a) palladium chloride, ferric sulphate, cupric chloride and sulphuric acid; and (b) palladium chloride, ferric sulphate and sulphuric acid; the reduced catalyst solutions are freed from olefines and carbonyl compounds and are regenerated by treatment with oxygen and nitric acid.  Specifications 876,025, 878,777 and 884,962 are referred to.ALSO:Aldehydes and ketones are produced by the oxidation of olefinically unsaturated hydrocarbons by bringing the olefine or a mixture containing it, together with oxygen, if desired, into contact at a temperature up to 200 DEG C. with an acid to neutral aqueous solution containing a compound of a metal of the platinum group and a salt of vanadium, chromium, manganese, iron, cobalt, nickel or copper, and the residual solution, after separation of the carbonyl compounds formed and in the absence of the hydrocarbons is reacted with oxygen and a compound of nitrogen and oxygen.  Preferably 2-20 gms/litre of the platinum group metal compound is used with a larger proportion of the other metal.  The preferred temperature range for the process is 50 DEG C.-170 DEG C. under a pressure of 1-50 atmospheres gauge. Suitable compounds of oxygen and nitrogen are nitric oxides or nitric acid.  Any part of the apparatus in contact with the oxidising solution should be made of corrosion-resistant material. In the examples ethylene is oxidised to acetaldehyde and 1-nonylene is oxidised to n-heptylmethyl ketone. Specifications 876,025, 878,777 and 884,962 are referred to.
