Patent GB-1072083-A (GB)
Title: Numerically controlled contouring system
IPC: G05B19/39
Filed: 1965-03-15
Abstract: 1,072,083. Electric calculating apparatus. HITACHI Ltd. March 15, 1965 [March 16, 1964], No. 10885/65. Heading G4A. [Also in Division G3] In a numerical control system for a machine tool, whereby co-ordinate contouring incremental command pulse trains are generated in response to a programme, the locus of a cutter centre is offset by controlling the co-ordinate movement of the machine tool by pulse trains formed by synthesis from contour increment command pulses and pulses derived from a circle having a radius equal to that of the cutter. As shown, co-ordinate information from a device F is fed through a control circuit D to a conventional command pulse generator A supplying incremental pulse trains to a synthesizing circuit E and signals to a circuit C indicative of the direction of movement along the commanded contour. The circuit D also channels offset information to the registers of a circuit B providing offset pulse trains to the circuit E and signals x, y to the circuit C indicative of points on the circumference of the circle having a radius equal to that of the cutter. The circuit C derives a parameter S, dependent on the tangent to the commanded contour, which through circuit D, Fig. 10 (not shown), ensures that the values of x, y stored in B are such as to maintain the parameter S at zero. Circuits A, B are operated by D when the desired contour is continuous, i.e. S changes sign when passing through zero, but should a discontinuity occur, Fig. 6 (not shown), A, B are switched off until the new set of conditions have been satisfied. Prior to a contouring operation pulses are derived from a circuit B<SP>1</SP> and fed to circuit E to displace the cutter centre from an origin to a position derived from the registers in the circuit B, this action being reversed when the contouring operation is completed. The arrangement and method of operation of the circuits B, C, D is described in detail for a typical contouring operation.

Filed: 1932-04-18
Abstract: 396,501. Organs &c. BROAD, J. J., 24, Corfton Road, Ealing, and COMPTON ORGAN CO., Ltd., J., Chase Road, Willesden, both in London. April 18, 1932, No. 11072. [Class 88 (ii).] The stop keys of an organ control the circuits of coloured electric lamps so that parts of the console and/or a stage or auditorium are differently illuminated to suit the tone of music played. The intensity of illumination is increased as the swell pedal of the organ is depressed. As shown in Fig. 1, the wings and seat of the console comprise metal framework 4 to which ornamental translucent panels are secured. Lamps of various colours are mounted within the panels and are controlled by the stop keys of the organ. Fig. 2 shows a suitable control circuit, the diapason, flute, strings, tuba and trumpet keys, marked D, F, S, T and T<1> respectively, controlling white, blue, yellow, red and orange illumination, through the relay circuits shown, the supply for lighting the lamps being indicated at 12 whilst 13 is a lowvoltage supply for the control circuits.. The swell pedal 17 carries contact 16 which cooperates with contacts 15 to control relays 14, the relays shorteircuiting more or less of the resistance 10, connected in series with the coloured lamps, to control the intensity of illumination. An alternative arrangement in which when a key is depressed the intensity of illumination of the lamps is gradually increased is indicated in Fig. 3, the circuit for the diapason key only being shown. When the key is closed the solenoid 24 is energized and moves 21 over contacts 20, the rate of movement being controlled by dash-pot 25. As 21 makes the various contacts more of the resistance 18 is shortcircuited and the white illumination is gradually increased in intensity. Similarly when D is opened, 21 moves back slowly and gradually extinguishes the lighting. According to the Provisional Specification an induction coil may be provided to cause brilliant flashes, required for storm music, and streamers of tulle or other light flexible material may be agitated by a current of air from a fan and illuminated with yellow and red light to give a fire effect.

Abstract: 661,309. Machines for moulding soil blocks. WARNE, A. S. April 26, 1950 [April 26, 1949], No. 11086/49. Class 87(ii) A machine for moulding soil blocks for plants and seeds comprises a tubular mould 19, a ram 41 to compress the soil, a co-axial plunger 42 to create a central depression in the moulded soil and a bottom plate 23 for ejection of the block. The ram 41 and plunger 42 are manually actuated: through cams 46, 47 and rods 36, the cams being so arranged that the ram is depressed before the plunger and the plunger raised before the ram. Helical compression springs 39 disposed between a fixed guide bracket 37 and stops 40 on the rods 36 urge the rods upwards. Three moulds 19 may be arranged on a rotary table 13 to come in turn to loading, moulding and ejection stations around the table. The ejection plates 23 are actuated by an annular cam 32 having a single high point 31 at the ejection station. Three angularly spaced stops 49 corresponding to the three stations are carried on the table 13 and the table may be correctly located by interposing a hand-operated lever 50 in the path of any of the three stops. Mounted on the same shaft 54 as the lever 50 is a second lever 53 the end of which normally lies in a slot 55 in the annular cam 32 exactly under the moulding station. When, after the moulding operation, the lever 50 is moved away from its stop 49, lever 53 rises simultaneously and slightly lifts the plate 23 and the soil block in the mould, thereby preventing adhesion between the mould and the soil. The moulds may be disposed beneath the table 13. The table may be rotated mechanically from the cam shaft 48.
