Title: Push button tuning device
IPC: H03J5/12
Filed: 1964-03-23
Abstract: 994,768. Push button tuners. R. HOPT. March 23, 1964 [March 26, 1963], No. 12164/64. Heading H3Q. In a push button tuner, the member operated by the buttons may be moved laterally by the button in dependence upon the setting of a selector associated with the button so that the operated member engages one or other of two tuner units, e.g. UHF and VHF. The button heads 3 are secured on push bars 2 having adjustable extension rods 5 which, when the button is pushed, rotate the rocker 21 and thus set, by means of extensions 23<SP>1</SP>, 23<SP>11</SP>, one or other of the tuners 24, 28 to the desired position. The button heads carry a selector block 25 which, when slid downwardly by means of exterior lateral projections, rotate a bar 10 about a pivot 9 so that a projection 12 enters a slot in a bar 16. Operation of the button then causes extension 12 to engage surface 18 of the bar sliding it and thus the rocker bar to the left against the action of a spring so that the rocker bar operates tuner 24 and is disengaged from 28. Accordingly, any of the buttons may be used to operate either UHF or VHF tuners 24, 28 depending on the setting of selector blocks 25 in the button head.

Abstract: 514,114. Stapling continuous filaments. GROVES, W. W. (I.G. Farbenindustrie Akt.- Ges.). April 27, 1938, No. 12574. [Class 120 (iii)] A sliver of cut fibres is formed from a band of continuous filaments by feeding the band through a knife-edged slot in a member, and in a direction oblique to the slot and cutting it by a rotating sickleshaped knife co-operating with the knife edge of the slot to give a shearing cut obliquely through the band. As shown, two bands 1 are fed through a pair nf knife-edged slots 4 in a frame 3 and are cut by the sickle-shaped knife 6 mounted on the rotating shaft 5; the cut bands are brought together at draft rollers 7 so that the oblique cuts in the bands cross one another. There may be more than one knife and the staple of the fibres may be varied by adjusting the feed of the bands and the number and speed of the knives. The number of slots in the frame 3 may be varied, e.g., there may be four slots and the four cut bands may be united in pairs to produce two slivers lying in different planes. Specification 509,406 is referred to.

Abstract: 128,895. Soc. Industrielle de Produits Chimiques. June 22, 1918, [Convention date]. Addition to 136,833. Ammonium and sodium sulphates.-The process described' in the parent Specification for treating the double salt (NH4)2SO4.Na2SO4.4H2O prepared by the action of ammonia on sodium bisulphate by heating it with water to about 110‹ C. to separate anhydrous sodium sulphate; and, after filtering, cooling the mother liquor to separate ammonium sulphate, is carried out in the apparatus illustrated. A charge of the double salt, water, and a small quantity of ammonium sulphate is introduced into the vessel A, and is heated by a steam coil and agitated. When a temperature of 110- 111‹ C. is reached, the contents are passed into a filter B heated by a steam jacket. The mother liquor is passed into a vessel E and is cooled to 62‹ C. Ammonium sulphate, together with' a small quantity of sodium sulphate, crystallizes. and is separated in a filter F. The mother liquor is concentrated in an apparatus I, and is returned to the vessel A together with a quantity of the double salt and a small quantity of sodium sulphate sufficient to obtain a charge of the original composition. The sodium sulphate in the filter B is washed with a nearly boiling and saturated solution of sodium sulphate from a reservoir C. The wash-water passes either into the vessel E or into a reservoir D. The ammonium sulphate in filter F is washed with a solution of ammonium sulphate saturated at 60‹. The wash-water passes either into apparatus I or to a reservoir H.

Title: Program control device for a calculating or like machine

Abstract: 1,139,925. Mechanical calculating apparatus. ING. C. OLIVETTI & C., S.p.A. 24 March, 1966 [31 March, 1965], No.13006/66. Heading G4B. In a ten-key keyboard calculator capable of performing 20 different basic operations each initiated by positioning a programme cam-shaft in one of 20 positions, depression of a control key causes the cam-shaft to be stepped through an appropriate sequence of its 20 positions to effect the desired calculation. Thus, depression of the "multiply" key 15, Fig. 1, causes the camshaft 27 to advance sequentially through positions VI, VII, XII, and XIV which cause respectively, "set multiplier", "effect multiplication", "print multiplier" and "print product". The calculator includes 10 slides 121- 130, Fig. 5, each of which, when released, causes, by means of an associated cam 111-120, the programme cam-shaft to step through a particular sequence of positions. The control keys are so arranged that each partially releases a group of slides and some keys additionally fully release a slide. Thus some slides are only released when an appropriate combination of control keys are actuated (e.g. if before the "multiple "key 15 is depressed a non-motorized lever 337, Fig. 7, is moved to its "accumulate multiplicand" position then an additional slide (124 as well as slide 121) is released when the "multiple" key is depressed and the programme cam-shaft also stops in position VIII, in which position the multiplicand is entered into a specific totalizer). Thus actuation of one or more control keys release one or more slides which cause the programme cam-shaft to stop at the appropriate positions.

Title: -ethods and apparatus for alternating-current arc welding
IPC: B23K9/10
Filed: 1972-03-21
Abstract: 1424797 Welding by fusion NATIONAL RESEARCH DEVELOPMENT CORP 15 March 1973 [21 March 1972] 13172/72 Heading B3R [Also in Division H2] In a method of and apparatus for gas shielded arc welding using a non-consumable electrode the voltage applied between the electrode and workpiece periodically alternates in polarity and the arc current varies cyclically at a repetition frequency which is lower than the repetition frequency of the voltage alternations. A typical voltage and current waveform envelope 30 is as shown in Fig. 2 in which the voltage and current increase steadily, are held at a constant value and then decrease to zero there being periodic superimposed reductions 39 in the magnitude of the average current. The applied voltage may be in the form of alternate positive and negative pulses or alternatively as shown in Fig. 3 groups of pulses of one polarity may alternate with groups of pulses of the other polarity and the periodic reduction in magnitude of average current (line 35) may be achieved by reducing the duration of the voltage pulses 33 as compared with pulses 36 which provide a higher average current 37. In a circuit, Fig. 4, for providing a waveform of the type shown in Fig. 3 a three phase supply is connected through a bridge rectifier system 13-18 to pairs of thyristors 24, 27 and 25, 26 connected to terminals 28, 29 representing the arc gap and thyristors 48-51 are provided to commutate the thyristors 24-27. A servo system for controlling the welding current includes a transformer 57 which provides one signal to a subtraction circuit 58 the other signal to which is of the general envelope form as shown in Figs. 2, 3 and is provided by a reference circuit 59. Reference circuit 59 is fed with a first envelope component comprising a rising portion, constant value portion and decreasing portion from control -circuit 74 through differential amplifier 15, time setting resistors 72, 73, diodes 70 and amplifier 66 while a control circuit 79 through a bi-stable circuit 76 automatically selects first and second proportions (one of which may be unity) of the first component for application to the subtraction circuit 58. The output signal from the circuit 58 is fed via amplifier 61 to a logic circuit 62 in which it is used to control the duration of pulses provided at a frequency determined by a variable frequency oscillator 77 with frequency control 78. The thyristor drive circuit 63 amplifies the firing signals from the logic circuit which control the firing of thyristors 24-27 and commutating thyristors 48-51. A high frequency oscillator 80 is provided for igniting the arc at the commencement of a welding cycle. In an alternative circuit arrangement (Figs. 1 and 7, not shown) for producing the required waveform bridge-connected thyristors are used (instead of the rectifier 13-18) to provide suitably phase controlled pulses to the thyristor pairs which are connected to the welding terminals.
