Title: Process for the production of hydrogen peroxide and the hydrogen peroxide so produced
Inventor: RUST FREDERICK F
IPC: C01B15/026
Filed: 1953-12-23
Abstract: The oxidation of secondary alcohols in the liquid phase with gaseous oxygen to produce hydrogen peroxide is effected in the presence of a "sequestrative hydrogen peroxide stabilizer", i.e. a compound, other than a compound of boron, which inactivates substances which tend to catalyse the decomposition of hydrogen peroxide.  Compounds specified are: organic cyanides, alpha-hydroxyquinoline, acetanilide, benzoic acid, alpha-benzoyloxy-beta-dimethyl-aminobutyrine acid, glycerine phenyl ether, thiourea, sodium salicylate, thymol, gum arabic, albumin, uric acid, guaiacol, phosphatides, acetyl glycol, monoacetyl glycol ether, sodium benzenesulphonate, hexamethylenetetramine, alkali metal salts of the oxy-acids of tin, antimony, silicon and aluminium and the hydrous oxides of these elements, and the oxyacids of phosphorus and alkali metal salts thereof.  The presence of the stabilizer may be ensured by rinsing the reaction vessel with a solution of the stabilizer and additional stabilizer may also be added to the alcohol.  In a continuous process the stabilizer may be added continuously or intermittently to the alcohol either in the reaction vessel or being fed thereto.  Alcohols specified are isopropyl alcohol, secondary butyl alcohol, the secondary amyl alcohols, cyclohexyl alcohol, 3,3,5-trimethylcyclohexyl alcohol, ethyl allyl carbinol, 2-cyclohexene-1-o1 and 1-phenylethanol.  Free radical initiators may be employed.  The oxidation may be carried out at 70-160 DEG  C., preferably 90-140 DEG  C.

Title: Banknote dispensing machine
IPC: G07D9/00
Filed: 1975-08-29
Abstract: 1498097 Dispensing banknotes INTER INNOVATION AB 29 Aug 1975 [29 Aug 1974] 35741/75 Heading G4X [Also in Division B8] In a machine for dispensing a desired number of banknotes the notes are fed sequentially from a stack 12 to a compartment 26, the bundle formed is fed to a slot aperture 6, there is diverter means 37 for diverting a bundle from the aperture if it does not contain the desired number of banknotes or which contains notes fed as bank notes. A primary friction feed roller 13 feeds notes past stripper roller 15 to roller 14. They are conveyed around the roller to compartment 26 where the leading edges abut a stop 25. The length of the compartment is slightly less than the length of the notes. When a note abuts stop 25 the rear end thereof is pushed away from the path of an incoming notes by ratchet teeth 17. Detector 42 determines if there is a simultaneous passage of plural banknotes. When the correct number of notes has been fed the stop 25 is moved anticlockwise about pivot 33 which also causes belt 27 to move upwardly. Diverter means 37 is pivoted anticlockwise about pivot 40 and the bundle of notes is fed to aperture 6. If the feeding of a plurality of notes simultaneously is noted then the feeding of further notes is stopped and the bundle is fed to auxiliary compartment 36. The completion of a delivery cycle may be completed before the bundle is diverted to compartment 36. A further cycle is then effected so that the correct number of notes are dispensed. The machine is used in conjunction with a credit card and the insertion of a "secret" number. The delivery of a bundle of notes may be inhibited until the card is withdrawn from the machine. Warning and safety devices may be incorporated to indicate when the dispenser is empty and compartment 36 is full. The dispensing means, control means and storage means are mounted in a cartidge that can be fitted as a unit in a box-like easing (1) Fig. 2 (not shown).

Title: A mechano-electrical coupling device
IPC: H01L41/18
Filed: 1968-07-26
Abstract: 1,243,993. Piezo-electric crystals. HITACHI Ltd. 26 July, 1968 [2 Aug., 1967; 18 Sept., 1967], No. 35906/68. Heading HIE. [Also in Division H4] An electromechanical transducer utilizes the ferroelastic/ferroelectric properties of certain crystals, e.g. Rochelle salt, potassium dihydrogen phosphate (KDP), gadolinium molybdate (GMO) and methylammonium aluminium sulphate dodecahydrate (MASD). These crystals have the required properties at a temperature below a certain phase-transition point (Curie point) which may vary over a considerable range, e.g. for GMO it is 160 C., for KDP it is - 150 C. The Specification gives a list of crystal classes in which substances having the required properties are found and the relevant phenomena are discussed at length. The case of GMO is also discussed in Specification 1,243,994. The crystals exhibit E-field vs. E-polarization and stress vs. strain hysteresis characteristics whereby application of mechanical forces or electric fields comparable to the coercive stress or coercive field results in reversal of the spontaneous polarization or spontaneous strain of the crystal and it is stated that a large increase in electromechanical efficiency results from these reversals. The theoretical nature of "spontaneous polarization" and "spontaneous strain", are explained in the Specification. As shown in Fig. 7(a), a 5 mm. cube 1 of 45 Z-cut KDP (cut parallel to the surfaces [001], [110] and [110]) whose [001] surface is provided with an electrode 2 is disposed in a hollow cylindrical pressure cell 3 of pyroferrite. The arrangement is dipped in liquid N 2  and pressure applied by pistons 5. A voltage of about 5 kv is obtained across the electrodes and fed to a capacitor (Fig. 7b, not shown). The arrangement may be used as a transducer for closing the contacts of a relay (Fig. 8, not shown). The Specification describes a bimorph (Fig. 9, not shown), for use, e.g. in a pick-up, comprising two elongated GMO elements each cut from a single crystal perpendicularly to the c axis and affixed to either side of a resilient cantilever. The c axes are arranged in the same direction and electrodes arranged on the exposed faces. The bimorph operates in a bending mode. The Specification also describes a voltage transformer (Fig. 12, not shown), using two pairs of electrodes arranged on a 45 Z-cut GMO element (i.e. cut parallel to the [001] and [110] faces which are perpendicular to the c axis. The voltage ratio between the two pairs of electrodes is stated to be 100: 2.

[Class 56] [See also Groups XXII and V] Moulds for centrifugally casting fusible materials of all kinds, including glass and metals, are formed by introducing a pulverulent refractory substance, such as silica, sands, or quartz, into a shell, applying it against the wall thereof by centrifugal force, and then glazing the inner wall of the refractory material by fusion. A shell A, which may be of prismatic, cylindrical, pyramidal, or conical form carries roller tracks F, G, and is rotated about its axis to cause refractory material R introduced along its axis to be applied to the walls. The material is then dried and the inner surface thereof fused and glazed by an electric heating element L mounted on a carriage M and introduced through a hole O axially of the mould. A gauge or templet may be used to shape the surface of the material before glazing. The material N to be moulded is introduced through a second hole O<1> normally closed by a plug P. The glazed shell R may be removed after the moulding operation and used in further operations.

[Class 38 (v).] A method of preparing a sound record consists in recording the impulses reproduced from an original record and modifying one or more passages by means automatically introduced by the original record, and a multi-contact switch is provided for controlling the arrangements desired. The switch may comprise a series of vertical insulated metal strips f<1> connected side by side and encircled by a yoke g<1>, Figs. 4 and 6, consisting of a rear member h<1>, side members k<1>, and a front member 11 having a series of inwardly-projecting contact studs r<1>. The strips f<1> are all provided with a number of equally spaced holes m<1> arranged as shown in Fig. 4 in a series of horizontal rows. Each of the metallic strips f<1> is connected to one side of the various circuits in the unit q while the bar P and yoke g<1> form the return lead. Metal studs n<1> adapted to make contact with the projecting studs on the bar l<1> are inserted in each row in those holes m<1> corresponding to the circuits in the unit q which are desired to be used in the various stages of operation. The rear member h<1> of the yoke g<1> is provided with a toothed ratchet i supported by a wheel x<1> on a shaft w<1> as shown in Fig. 6. The yoke g<1> is normally held in position by the engagement of a pair of pivoted pawls t<1>, u<1> with a toothed wheel v<1> on the shaft w<1> as shown in Fig. 3. The pawls t<1>, u<1> are connected together by a link a<2> which is pivotally attached to a rod s<1> adapted to be operated either by a rod o<1> for manual operation or by a solenoid d<1>, Fig. 3, so as to cause the pawl t<1> to release the wheel v<1> and allow the yoke g<1> to be lowered to the next row of holes. The solenoid d<1> is controlled by a switch a<1>, b<1> adapted to be closed by a series of notches previously formed in the edge of the original film at the places where different modification is desired. The switch a<1>, b<1> comprises a roller w carried by a spring-controlled pivoted arm x. The arm x is pivoted on an insulated base e<1> slidable at right angles to the film and held against the edge of the film by a spring so that when the film is withdrawn the contacts a<1>, b<1> are maintained out of engagement. If desired, the yoke and contact strips may be fixed and the contact points may be separated by a movable card or flexible band having perforations or metal studs at suitable points along its length. A card in which suitable holes are punched may be used as a spacing card for setting the studs n<1>. In place of notches on the film the latter may be provided with metallic surfaces for completing the solenoid circuit, or with transparent portions through which light may be passed to operate a light-sensitive relay.
