Title: Organ percussion system
IPC: G10H1/14
Filed: 1967-06-19
Abstract: 1,124,549. Organ percussion systems. HAMMOND CORP. 19 June, 1967 [23 June, 1966], No. 28068/67. Heading G5J. In an organ percussion system, a variety of effects, e.g. chime, xylophone, glockenspiel, piano, is achieved by combining the synthesis and formant approaches. As shown in Fig. 1, each signal lead from a bright wave generator 10 is connected to a percussion keyer at 12, controlled by a playing key at 16, and the outputs from the keyers are collected in half octave groups (excepting the low-frequency octave 13-24), amplified at 14 and filtered at 22 to leave only the fundamental sine waves. A harmonic selector matrix 18, controlled by tabactuated contacts at 20, is used to choose the finally synthesized harmonic content of the tone signals fed to the output. Other tab-actuated contacts control keyers 12 to determine the choice of a short, medium or long decay envelope. Signals from the filters 22 are amplified at 28 and passed to the output 30 via the tab control system 20. The output may be connected through reverberation or vibrato systems, swell control mechanisms and power amplifiers to one or more speakers. Leads 24 from the drivers 14 are also connected to individual piano and banjo formants 32, which attenuate certain frequencies and enhance others to give tone coloration. The piano and banjo tones, taken from the formants 32 through separate leads 34 and 38, respectively, pass through preamplifiers 36 and 40 and via the tab controls 20 to the output 30. The keyboard 16 includes an arrangement for reiterating the percussion envelope, and a mechanism for playing arpeggios.

Abstract: 489,351. Electrical precipitation apparatus. BRITISH THOMSON-HOUSTON CO., Ltd. Oct. 17, 1936, No. 28277. Void. Convention date, Oct. 17, 1935. [Class 39 (i)] A method of purifying a gas electrically at a pressure of the order of atmospheric comprises imparting to electrically charged liquid or solid impurities in the gas a volt velocity amounting to a multiple of the potential existing between a source of ions and a collecting electrode by subjecting said particles to successive accelerations in a series of accelerating fields which alternate with field-free spaces. The drawing is a diagrammatic representation of the apparatus. The gas to be purified enters the electrofilter at A, and passes an ionizing number consisting of emitting wires 1, which are connected to the negative plate of a condenser C. The gas then passes successively through accelerating fields 1, 2; 3, 4 ; 5, 6 ; and 7, 8 with intervening field free spaces 2, 3 ; 4, 5 ; 6, 7 &c. so that when the ions have traversed a sufficient number of the accelerating fields the volt velocity becomes high enough for separation to occur at the grid bars, 4, 6 &c. The ionizing member may alternatively consist of a vapour stream ionizer, hernst filament, &c.

Title: Improvements in vulcanizers
IPC: B29D30/06
Filed: 1933-10-14
Abstract: 421,300. Vulcanizing tyres. BRIDGE & CO., Ltd., D., Castleton Iron Works, Castleton, Lancashire.-(National Rubber Machinery Co. ; Akron, Ohio, U.S.A.) Oct. 14, 1933, No. 28431. [Class 70] A watch-case vulcanizer is locked by the operation of arms pivoted to one member and carrying pivoted wedgeblocks engaging lugs on the other member. Arms 42, Fig. 2, pivoted to the lower member 11 at 43, and operated by a cylinder and piston 45, 47, carry wedge blocks 50 which engage lugs 53 on the upper platen 21. The blocks 50 are square and are mounted eccentrically on pivots 49, so that by turning them round, the effective length of the arms may be varied. Overhanging lips 51 on the arms allow of slight rocking movement. To open the press, a valve 36 is opened by a handle 59 to admit pressure by a pipe 67 to the forward end of the cylinder 45 to withdraw the blocks 50, and by a pipe 63, Fig. 1, to a cylinder 27, the piston 26 of which is pivoted to an extension 24 of the upper platen 21. The relative sizes of the cylinders are such as to ensure unlocking before opening. As the press opens, a pin 25 is engaged successively by notches 31 on a swinging latch 29 to prevent accidental closing. To close the press, the valve 36 is manipulated to exhaust cylinders 27, 45, the latch 29 is tripped by levers 32, 33, 34, and handle 35, and the press closes under its own weight. The valve 36 is then operated to pass fluid pressure by a pipe 66 to the cylinder 45 to lock the press, by a pipe 16 to a bag 15 to press the mould halves together, and by a pipe 57 to the interior of the work 56. The friction between the blocks 50 and lugs 53 is such that the press cannot be unlocked until the internal pressure has been released.

Abstract: 693,812. Honing apparatus. MID - WEST ABRASIVE CO. Dec. 4, 1951 [Dec. 13, 1950], No. 28432/51. Class 60. Apparatus for honing a bore 70, Fig. 1, includes a reciprocating tool 10 and a gauge 87 which enters the bore under the action of means interposed between it and the tool when the bore has reached its final size, and means for discontinuing reciprocation of the tool in response to the movement of the gauge. The tool includes a head 11 carrying abrading elements 16 mounted in shoes 22 which are held in contact with cones 20, 21 by garter springs 24. The cones are connected by rods 44, 45, Fig. 2, to a piston 43 which under control of a valve 59 may be caused to displace the cones axially to contract or expand the elements 16. The cylinder for the piston 43 is formed in one end of a spindle 36 connected to a driving member 80, Fig. 5, which is reciprocated by a piston 74 under control of a four-way valve 77 and rotated by a slidably splined gear 79 driven from an electric motor 77'. The valves 59 and 77 are operated by solenoids forming part of a circuit which also includes the switch for the motor 77' and a microswitch having an arm 89<SP>1</SP> operated by the movement of the gauge into the bore to stop the machine and collapse the abrading elements. To allow for misalignment of the head 11 with respect to the member 80, the drive is transmitted through intermediate members 13, 25, having a spherical seat formed between their abutting ends and connected rotationally and axially by slots 27, pins 26 and a sleeve 29, while the rods 44, 45 are connected by a pivot pin 47 which also passes into slots 48 in the member 13. The gauge 87 has three radially-ended lugs corresponding to the final size of the bore and bolted to similar lugs on a housing 86 rotatably mounted on bearings 88, 89 on the member 25 and connected by arms 85' to a ring 87<SP>1</SP> which operates the switch arm 89<SP>1</SP>. In a modified form of gauge, the gauging surfaces are formed by three radially-adjustable micrometer screws. The gauge may have a chamfer 99 to pilot it into the bore and is pressed into contact with the latter by a coil spring 96.

Abstract: 971,650. Pressure gauges. LEYBOLD HOCHVAKUUM-ANLAGEN G.m.b.H. Aug. 8, 1961, No. 28564/61. Heading G1L. A gauge for measuring vacuums comprises housing 1 containing a hollow sealed deformable pressure sensitive element 2 containing a vapour forming substance, means being provided for supplying approximately constant heat energy to the element 2. At pressures above about 10 Torr the coefficient of thermal conductivity of element 2 is almost constant and the gauge functions in a conventional manner the pressure to be measured being supplied to housing 1. At pressures below 10 Torr the heat dissipation of element 2 is impaired and in the range 10- 10<SP>-3</SP> Torr the coefficient of thermal conductivity depends on the pressure. This causes an increase in temperature of element 2 and a consequential increase in the vapour pressure therein. This can be used for indicating purposes. In the embodiment shown in Fig. 4 the pressure sensitive element 2 is a Bourdon tube, the indication is by means of a spring biased pointer 9 and the element is heated by passing a current through it. In another embodiment the pressure sensitive element is a capsule, the indication made by the closing'of electric switch contacts and a heating coil is applied round the pressure sensitive element. A vapour filled pressure sensitive element 26, Fig. 6, according to the invention may be combined with one or more elements 22 of known construction to form a common control for a pointer or switch contact.

Title: Process for the manufacture of solutions from cellulose or derivatives of cellulose
IPC: C08B1/00
Filed: 1924-11-28
Abstract: The viscosity of solutions of cellulose or of cellulose derivatives, such as solutions of viscose, is determined by the absorptive capacity for alkali solution of the original cellulose material; the absorptive capacity is measured by determining the weight of a solution of caustic alkali of standard strength that will be absorbed by a standard weight of the material, for instance, in the form of pasteboard.  As the absorptive capacity is higher, so must the ripening of the alkali cellulose be permitted to proceed to a greater extent, either by prolonging the process or by the employment of a stronger caustic alkali solution, say, of 24 per cent as compared with the normal 18 per cent strength.

Abstract: 1495065 Alerting system for vehicle drivers NISSAN MOTOR CO Ltd 8 July 1975 [8 July 1974] 28667/75 Heading G3T  A safety system for alerting a drowsy driver of a motor vehicle comprises means to operate a warning device if no signals are produced by one of two sensors responsive to movements of the steering wheel and accelerator pedal respectively, within a predetermined time interval from the last signal therefrom or within a time interval which is dependent upon the speed of and distance travelled by the vehicle. In Fig. 1, sensors 10, 12, 14 produce outputs representative of vehicle speed, steering gear movement, and accelerator pedal movement respectively. An integrator 18 integrates the speed signal to produce a distance travelled signal. A reference voltage generator 22 produces a voltage proportional to the speed signal. A comparator 24 produces a logic "1" output when the magnitude of the distance travelled signal exceeds the reference voltage, indicating that the driver is inactive and drowsy, which output causes energization of a warning device 26 to alert the driver. The warning device may automatically switch on a lamp, a buzzer, a radio, or vibrate the drivers seat or open a window. A manual switch 28 is provided to reset the integrator and to switch off the power supply to the warning device if not required. An OR gate 16 produces a logic "1" output when a signal from either sensor 12 or sensor 14 is received, which output causes a circuit 20 to reset the integrator to its initial state, as described with reference to Fig. 2 (not shown), which prevents the operation of the warning device. Alternatively the integrator may be connected to a timer to produce a signal at the end of a predetermined time interval; if the sensors 12 or 14 produce no output in that interval. The steering wheel sensor may produce a logic "1" each time the wheel is moved through a predetermined angle, or oscillations of the wheel may produce pulses from a photo-electric type sensor.
