Abstract: 850,659. Vehicle head-lamps. POPELAR, V., and VYROUBAL, L. Sept. 9, 1957, No. 28368/57. Class 75(3). A headlamp for a vehicle, additional to the two normally provided side fixed headlamps is turned in the horizontal plane from the steering of the front wheels of the vehicle up to a certain angle of steering in which the headlamp is turned faster than the wheels and, independent ly of the turning of the headlamp it is also pivoted about an axis to assume a dipping position to produce a dipping of the light beam, the pivoting taking place simultaneously with the dimming of the fixed headlamps. As shown, the lamp holder 22, Fig. 1, is carried by the reinforced end of the parabolic reflector 14, which end is widened into a flange 23. The centre reinforced end is inserted between two adjustable ball supports 42, 44, Fig. 2, the balls being mounted in sockets 43 on an axis inclined to the vertical and pressed into the flange 23. This flange 23 carries on one side the armature 37, Fig. 3, of an electro-magnet 36 the core of which is rigidly secured to the body 18 of the headlamp. The electromagnet 36 is energised when the fixed headlamps are dipped thereby attracting the armature 37 and deflecting the reflector 14 from its normal position by an adjustable arrangement depending on the gap between the core and the armature. The turning movement about a vertical axis of the lamp is effected by a disc 27, Figs. 1 and 4, rigidly connected to a pin 7, Fig. 1, driven from the steering knuckle arm through lever 3, Figs. 1 and 2, an upper driving disc 26 secured to the body 40 of the headlamp and a lower accelerating disc 28 secured to the support 18 for the headlamp.

Title: Electronic music system
IPC: G10H1/053
Filed: 1973-06-15
Abstract: 1439957 Electronic musical instrument D H BALDWIN CO 15 June 1973 [16 June 1972] 28671/73 Heading G5J An electronic musical instrument comprises keys 2, voltage control oscillator 9, means 7 for deriving a control voltage which is a function of the tone of the key of highest pitch of a group of keys actuated concurrently, means 8 for applying said voltage after a predetermined time interval to allow for failure of simultaneity of actuation of the keys, and means for acoustically transducing the tone signals derived from said oscillator. Actuation of a key of higher pitch than is already activated on keyboard 2 causes said control voltage to be passed by voltage divider 3 to storage means (not shown) in sample and hold circuit 8, the voltage being connected to V.C.O. 9 after a 20 ms. delayed gating pulse is generated by note played detector 7. Releasing the key of highest pitch similarly provides a 40 ms. delay followed by a further 20 ms. second delay during which time the control voltage is sampled again. Circuit 8 allows for a smooth variation of the stored voltage for legatissimo playing, or a stepwise variation for staccatissimo playing. Square wave oscillations corresponding to the control voltage are output from V.C.O. 9 to the frequency dividers 10. The tones from the lower octaves of frequency dividers 10 are filtered by voice filters 11 which simulate one or more brass instruments; including voltage controlled flatting and subsequent brightening of the tones within a modulating envelope. The tones from the higher octaves are filtered by flute filters 12, one per octave, and passed to gates 14 (providing controllable sustain) and 15 (providing fixed, short sustain). Tones are also passed to wave shaper 22 which receives signals from noise generator 21 and gating signals from note played detector 7 as well, to generate various, selectable waveforms, e.g. shortened pulses, sawtooth waves. Output from wave shaper 22 passes to voltage controlled filter 13 providing low pass, band pass and high pass characteristics selectively. Vibrato effects are supplied to V.C.O. 9 and gating voltages are supplied to mode selector 19 by the low frequency modulation oscillator 20 which can be set in both a random and non-random mode, the latter mode using signals from noise generator 21. The mode selector 19 provides trigger pulses to various circuits along the control signal lines of Fig. 1. Tone signals from conventional tone generators 1 are switched via keys 2 to voicing circuit 4 which colours the tones before they are amplified by preamplifier 17 and amplifier 5 and transduced by loudspeaker 6 along with the tones from filters 11, 13 and gates 14, 15. Expression shoe 18 is used to control the effect of filters 11, 13 on the harmonic content of the tones and to vary the gain of preamplifier 17. The various modes selectable by selector 19 are reiteration, percussion, normal (continuous), fast attack, slow attack and sustain. Details of the various circuits indicated by the function boxes of Fig. 1 are described.

Abstract: 617,365. Winding webs. HALLEY & SONS, Ltd., J., and HALLEY, A. M. Sept. 27, 1946, No. 28846. [Class 100(i)] In a printing or like machine, the web d is unwound from a roll a and rewound on a spindle c' to form a roll c which is driven by rolls e driven by a roll g actuated by sprocket gearing from the printing- machine, and according to the invention a constant load equal to the length of a constant length of web is applied to the winding rolls e by mounting the rolls a, c in a common slide b which can move over a guide l. The slide b is carried by brackets b<1> having anti-friction rollers b<2> to facilitate movement over the guide l, and a counterweight p attached to a cable m limits the downward pressure on the slide b to that of the combined weight of the rolls a, c and as this is constant the load on the rolls e is constant. The slide b is fitted with anti-friction supports b<3>, and the slide b is detachably connected to the the ends of the spindle c<1> by means of catches q. In a modification, the winding roll is pressed into contact with its driving roll by a piston actuated by hydraulic or pneumatic pressure which is obtained by mounting the roll a in a bearing carried by a piston acting in a cylinder connected to the cylinder in which the first piston acts. As the weight of the supply roll is diminished, the amount of pressure transmitted is diminished, but the actual rewinding pressure is maintained constant due to the increasing weight of the rewound roll.
