Title: Improvements in and relating to electrical step by step mechanisms
IPC: G04C13/10
Filed: 1928-03-22
Abstract: 312,432. Parsons, I. H., and Ball, A. E. J. March 22, 1928. Reciprocating machines. - Electro-magnetically operated ratchet mechanism is energized from an electrical clock circuit to advance the typewheels of time-recording apparatus, and comprises a ratchet wheel A of 60 teeth fixed to a spindle B, a ratchet wheel D of 120 teeth loose on the same spindle and spring-connected to the " 60 '' ratchet wheel, and a lug E moving with the armature F, F<2> of the driving electromagnet H and coasting with the " 60 " wheel so that this wheel moves a distance equal to the pitch of its teeth for every two impulses of the electromagnet. A pin D1 on the wheel D projects through a slot A1 of the wheel A to coact with .a spring C anchored to the wheel A. When the magnet H is energized at half-minute intervals its armature lever F, F2, pivoted at F1, stresses a spring G3 and on the return movement to the left the driving pawl F3 advances the wheel D one tooth. The wheel A is held from rotation, however, by the lug E on the lever F engaging the teeth, so that the pin D1 flexes the spring C. At the next half-minute impulse pawl F3 and lug E are retracted and the spring C advances the wheel A <1>/120th of a rotation, the wheel D being held by the detent G2. On the subsequent movement to the left of pawl F3 the wheels A and D move <1>/120th of a revolution together. A stop G1 limits the drive of F3 to one tooth of wheel D.

Patent GB-1491623-A (GB)
Title: Electrical musical instrument with chord generation
IPC: G10H1/38
Filed: 1975-03-03
Abstract: 1491623 Electronic organ WARWICK ELECTRONICS Inc 3 March 1975 [24 June 1974] 8796/75 Heading G5J An electrical musical instrument with automatic accompaniment comprises a plurality of tone generators 46, chord selection means for developing signals representative of selected chords and including priority logic 40 for inhibiting all but one chord signal and a tone selection matrix 44 for selecting tone generators 46 which provide the notes required by the chord signal. The distinction between major and minor chords is made on line 58 which enables the correct one of gates 60, 66 to pass the major or minor third. Since the tone generators 46 cover only one octave some generated chords will be inverted, which inversion is detected by gates 82, 86 and corrected in dis-inverting gates 80 which merely raise certain notes by one octave. The output tones are frequency divided by dividers 70, 72, 74 so that arpeggio or strum effects may be generated by sequential gating matrix 130 under control of a counter 170 and an arpeggio/strum clock. Complex rhythms may be built up by rhythm unit 190. Operation of the chord detection logic 28 is described with reference to Fig. 2 (not shown), but chord signals may be generated by depression of either a single key or by the conventional three keys depending on the position of switch 29. In the one finger mode, a minor triad is selected by depressing the corresponding "sharp note". That is depression of G sharp generates a G minor chord. Complex chords containing other than root, third and fifth notes may be built up by including a "seventh" line 37. The accompaniment manual may be two octaves long and the keys colour coded to aid teaching of a beginner.

Title: Improvements in or relating to harvesters for turnips and like crops
IPC: A01D27/00
Filed: 1944-05-11
Abstract: 585,687. Turnip &c. harvesters. DOULL, G. May 11, 1944, No. 8988. [Class 6 (iii)] A turnip &c. harvester comprises a shawer or tops remover, a toothed ground plate which enters the ground to lift the turnips, a rotary cutter blade above and co-operating with the ground plate to sever the roots and a spade wheel to propel the turnips on to a moving grid. There may also be a pair of horns to gather into the line of the rows any turnips out of line and to lift into line any hanging down tops. The tops cutter, Fig. 1, pivoted at 3 to the frame of the harvesting machine (not shown) comprises scissor like blades 8 pivoted at 7, and co-operating with cutter blades 4, the blades 8 being oscillated by a bar 5 oscillated by the machine. The blades 8 may have no pivots 7 and so may be integral with the bar 5. The tops cutter arrangement is also attached by a slot 10 to the machine, the slot allowing lateral movement. A resilient bar 2<SP>1</SP> acts as a feeler bearing on the surface of the turnip to adjust the heignt of the cutter. Behind the cutter for the tops a pair of wheels with spring steep wire arms 14, Fig. 7, rotating in opposite directions whisk off any leaves left uncut. Alternatively, a rotary bristle brush 15, Fig. 11, may be provided for the same purpose, the frame of the brush being pivoted at 17 to the machine and lifted by the feeler arm 16 which contacts the upper surface of the turnips. The brush 1 can rise and fall through its sliding coupling 21, 22 to its drive shaft 23. The turnips are raised slightly from the ground by the dragging along of the ground plate 29, its teeth tips 30<SP>11</SP> being bent down so that the plate sinks a little into the ground until its V-notches 31 contact and raise the roots. The roots are then cut off by the rotating of the blades 33 co-operating with the serrations 31 of the notches. Instead of the blades 33 being mounted on a wheel, they may be mounted on an endless chain or belt (Fig. 5 not shown). This device is suitable where turnips are growing broadcast. The turnips having thus been topped and tailed are propelled on to a shaking grid 38 by means of the spades 421 of an inclined spade wheel 42 which is either driven from the machine or by contact of the inclined spades 42<SP>1</SP> with the ground asthe wheel is dragged along. The grid 38 is shaken from the. drive of an elevator the buckets of which may be formed of fingers 41 passing between the fingers of the grid 38. The delivery guide 40 may have like fingers.

Title: Improvements in or relating to Rectifiers for Alternating Electric Currents.
Inventor: HARTMANN JULIUS FREDERIK GEORG
IPC: H02M1/30
Filed: 1919-04-10
Abstract: 130,936. Hartmann, J. F. G. P. Nov. 14, 1918, [Convention date]. Commutator switching-arrangements. - In a rectifier for alternating currents, of the kind comprising a mercury or other conducting-liquid jet S passing through a magnetic field M and striking an electrode E, as described in Specification 102,977, an auxiliary source of current is inserted in parallel with the jet S in a circuit which includes a commutator, preferably comprising a subsidiary jet s traversing a field m, adapted to complete the circuit during the period in which the electrode E is impinged upon by the rectifying jet S. The auxiliary current maintains the motion of the jet independently of the rectified current, and permits the regulation of the rectified current to valves approaching zero. When the rectifying jet carries alternating current, the auxiliary current must be in phase with the current to be rectified and may be obtained from the same source as the main current through a separate transformer, as shown in Fig. 1, or by tapping the main transformer winding. In the arrangement shown in Fig. 3, the jet is alternately connected to half windings V<1>, V<2> of the transformer used and carries direct current. The auxiliary current is in this case supplied by a battery B, the fields M, m being alternating and supplied from the windings V<1>, V<2>. In a modification, batteries are placed in the leads connect. ing the subsidiary electrodes e<1>, e<2> with the main electrodes E<1>, E<2>. In the arrangement shown in Fig. 5, separate rectifying jets S<1>, S<2> are used for each half of the transformer winding, the auxiliary current being obtained from a battery B through a jet s traversing an alternating field m supplied with current from the same source as the current to be rectified. For rectifying polyphase currents, a rectifier with rotating field is used, as shown in Fig. 6, the auxiliary current being obtained from a battery B.
