Title: Improvements in and relating to stringed musical instruments
IPC: G10D1/02
Filed: 1919-04-14
Abstract: 143,362. Piper, F. B. April 14, 1919. Violins etc.; guitars etc.; devices to facilitate support; bridges.-For playing by plucking with one hand whilst being juggled or spun, violins, violas, cellos, &c. are provided with sufficient strings, e.g. seven, to give natural notes of a large part of a diatonic scale. To facilitate grasping whilst the instrument is spinning, the rear surface of the scroll e does not overhang the neck d. A peg f, either blunt-pointed or ball-ended and intended for rotary movement across a stage, is substituted for the usual tail-pin. The bridge b and nut c may be flat, to space the strings in one plane. The neck of smaller instruments of the type is so constructed as approximately to coincide with the longitudinal axis of the instrument. For cellos, a stationary base g may be provided to enable them to be maintained in spin for longer periods. The cello has a thrust bearing j in a socket i resting on the spindle k. The lower end of the cello may be loaded as indicated by l. For concealment of the base, the depth of the cello is greater than usual, so that the profile of the base is within the back and belly of the instrument. Another base for rotating the cello is as described in Specification 20088/06 with reference to banjoes.

Abstract: 796,488. Electric digital-data-storage apparatus. STANDARD TELEPHONES & CABLES, Ltd. March 22, 1957, No. 9512/57. Class 106 (1). [Also in Group XXXIX] In binary intelligence storage equipment, each bit is stored both as itself and as its complement in a pair of ferro-magnetic or ferroelectric bistable cells whereby one cell is in the " 0 " condition and the other in the " 1 " condition or vice versa, so that the load impedance presented to a read-out pulse source is substantially constant and independent of the stored intelligence. As shown, a pair of storage cells 5, 6 comprise holes in a ferrite block which may be as described in Specification 760,048. Gates 12, 14 are conditioned by input amplifier 11, directly and through inverter 13 respectively, whereby according to whether or not an input pulse is applied, a half-write pulse is gated via amplifier 15 or 16 to " column " wire 8 or 9 which together with a half-write pulse on " row " wire 10 sets cell 5 or 6 to the " 1 " condition, the other cell remaining in the " 0 " condition. To read out, a pulse is applied to wire 10 to reset all the cells to " 0," a significant or spurious output pulse being induced in the associated column wire according to whether the cell is in the " 1 " or " 0 " condition. The wires 8, 9 are connected to a differential amplifier 17 which obtains the difference between its two inputs, whereby its output is positive or negative according to the intelligence stored. The wire 10 may thread the different pairs of cells in parallel (Fig. 3, not shown). The cells may be separate magnetic cores.

Abstract: 815,326. Electric analogue calculating systems. GENERAL -ELECTRIC CO. March 28, 1956 [March 29, 1955], No. 9666/56. Class 37. [Also in Group XL (b)] An electric analogue computer deriving a signal representing a predetermined function of an input signal comprises a cathode-ray oscillograph whose beam is deflected along one axis in linear proportion to the input and along the perpendicular axis by a symmetrical timebase voltage; the tube screen being partially covered by a mask whose profile in the first scanning direction defines the law of the required function so that the screen illumination excites a light-sensitive device whose output is integrated and superimposed upon the timebase voltage to position the tube beam to deflect by approximately equal distances on either side of the mask profile and the output of the lightsensitive device represents the required function. The input signal is applied to the horizontal plates of an electrostatic deflection C.R. tube 14 whose vertical plates 11 are excited by a sawtooth generator 17, and the tube screen is covered by mask 16 whose profile 16a defines in the vertical sense a predetermined function in terms of the horizontal spot deflection. Illumination of the screen excites photo-cell 15 whose output is amplified and limited to a rectangular waveform 21 which is symmetrical when the vertical sweep is centred at the mask profile, but whose positive and negative excursions differ in length according to the sense and magnitude of any asymmetry of the sweep about the profile. This waveform is integrated at 22 to a unidirectional voltage 23 superimposed on the vertical deflection voltage to maintain the sweep centre at the mask profile at all points of the horizontal deflection due to the input, so that when filtered free of the sawtooth voltage it represents the required function. The C.R. tube may be magnetically deflected by appropriate currents.

Filed: 1917-07-10
Abstract: 107,979. Petit, H. July 10, 1916, [Convention date]. Differential speed indicators; measuring average speed.-The average speed during the time elapsed since a given epoch is measured by causing a pivoted arm to move according to the direction of the resultant of displacements represented by two co-ordinates PM, OP, Fig. 1, one assigned to distance and the other to time. A plate 3 is moved by a screw 4 and nut 5 at a speed proportional to that to be measured, and carries an inclined screw 6 which is driven by a time escapement 7 and moves a nut 8 proportionately to time across the plate. The nut 8 is provided with a pin 11 which engages a groove in the arm 10, the pivot 9 of which is above the pin 11 at the epoch of setting or zero time position, and the resulting angular position of the arm 10 is a function of the average speed over the interval and is communicated by a pinion to an indicator. To prevent movement of the nut 8 during periods of rest, the motion thereof may be derived through an escapement from the main driving-shaft 16 through teeth 17 and a pinion 18, the average speed measured being thus limited to the periods of motion.

Abstract: 944,817. Dry rectifier assemblies. SIEMENS-SCHUCKERTWERKE A.G. March 17, 1961 [March 30, 1960; Aug. 25, 1960; Sept. 16, 1960; Feb. 9, 1961], No. 9958/61. Heading H1K. Two sets of rectifier units are produced using the same automatic production machine. The units of the first set, which are all the same, each consist of a stack of rectifier plates in seriesaiding relationship with a metal plate at the centre of the stack and another at one end. The units of the second set, all the same, differ from those of the first set by the replacement of an equal number of rectifier plates on each side of the central metal plate by metal dummy plates. The first and second sets of units are mounted in first and second housings respectively to form rectifier assemblies. A typical assembly made in this way consists of units as shown in Fig. 1 embedded side by side in resin 12 in a flattened metal or insulator cup 11 (Fig. 2). Each unit comprises four plate rectifiers 1, central connecting plate 6, end contact 5, resilient plate 4 and insulating foil 2 clamped together by a clip 3 making electrical contact with plate 4. Plate 6, contacts and clip 3 have integral tabs extending therefrom in the same direction and spaced apart a suitable distance for fitting into standardised printed circuit arrangements. In the Fig. 2 assembly the clips in both units are formed with extensions through which they are connected in series opposition by metal strip 10, and the tab on the clip of the second unit is omitted. At least some of the tabs may be spirally twisted to increse their flexibility. In units for containing larger numbers of plates (Fig. 10), to prevent the clip springing open the resilient plates 44 are formed with projections 44a and the clip with slots in its lateral edges where it folds over the projections. In an alternative unit (Figs. 7 and 8) the holder consists of apertured insulating block 23 and a metal clip 27 located by wing portions 28 engaging shallow grooves 26 in the block and by a lip 29 on the block. The clip serves to hold the plates together and to electrically connect the bottom plate to a contact 22 insulated by plate 32 from the other contact 32. Various interconnections of the units in a common housing are described.
