Filed: 1923-03-22
Abstract: 214,065. Beames, H. P. M. March 22, 1923. Link-motions.-In a modification of Walschaert. gear for locomotives with inside cylinders, the supplementary lead- and-lap motion imparted to the combustion lever C is ta.ken from a crank pin on a driving- wheel or from a pin mounted in a driving-wheel coupling-rod A, and the pivoted link F is oscillated by a rod E connected to a return crank D on the driving-wheel crank-pin. When the valve-chest is arranged outside the frame, the lever C is directly connected to the valve.

Abstract: 1465053 Change-speed control LUCAS ELECTRICAL Ltd 12 Feb 1974 [20 Feb 1973] 8217/73 Heading F2D A control unit 16, selecting ratios in an automatic transmission on a motor vehicle, is controlled by a multi-bit digital input signal which it receives from a memory 10 in the form of a diode matrix having a number, e.g. sixteen, of first input lines 11a ... 11p, crossed by a similar number of second sets of input lines 12a ... 12p, each set 12 consisting of two separate lines with diodes, represented by dots, connected between the lines in a manner determined empirically in accordance with engine and transmission characteristics, the sets of lines being energized through decoders 14, 13 and analogue-digital converters 20, 18 by transducers 19, 17 responding respectively to engine parameters such as engine speed and throttle setting or intake depression. The decoder 14 operates to turn on one of sixteen sets of switches 15a ... 15p each of which connects one of the sets of lines 12a ... 12p to the control unit 16. For a given value of each of the two control parameters one of the lines 11 will be energized and one of the sets of switches 15 will connect one of the sets of lines 12 to the control unit 16, which will then operate to select the required gear ratio. Thus, for example, with a diode connection (dotted) representing 1 and no connection 0, 11a, 15a would produce a control signal 10, whilst 11b, 15p would produce 00.

Abstract: 1300246 Electrophonic musical instruments; pianos D H BALDWIN CO 24 Feb 1970 8894/70 Heading G5J A string termination or agraffe for an electropiano is designed to provide coupling between strings similar to that provided by the soundboard and bridge of a conventional piano and to permit use of a number of transducers smaller than the number of strings. The agraffe comprises a U-section aluminium rail E, Fig. 3, resiliently bolted to a string plate 10 by means of a bolt 33, grommet 32 and a layer of felt 30. The tuned portion of the string 11 terminates at a knife edge on the cantilever arm 17 of the rail E and a rubber damper 40 thereon simulates the damping of the strings by a conventional wooden piano bridge. In a modification, the damper may be pressed on. to the top of the string with variable pressure to provide variable decay rates. A number of ceramic piezo-electric transducers 20 smaller than the number of strings is located within the rail separated by rubber dampers 26 from the cantilever arm 17. The static pressure on the transducers 20 is sufficient to prevent them coming loose even when the piano is played at full amplitude. The aluminium rail E may be replaced by one of soft iron and the piezoelectric transducer by magnet coil transducers.

Title: Improvements in or relating to tape dispensers
IPC: B65H35/00
Filed: 1946-03-22
Abstract: 609,875. Tape dispensers. MINNESOTA MINING & MANUFACTURING CO. March 22, 1946. No. 8897. Convention date, April 4, 1945. [Class 18] The severing device of a tape dispenser releases a catch member engaging a stop on a measuring roll when a length of tape is severed on the device thus permitting another length of tape to be withdrawn. As described, a roll of pressure sensitive adhesive tape is supported between two walls and is fed over a measuring roll 22 to the severing device 41. The measuring roll 22 is mounted coaxially with a disc 28 and imparts rotational movement to it through a pin 28a on the disc engaging a spring 27 mounted in a recess 22a in the side of the roll. Ridges x, y, z, of different lengths are provided on the face of the disc to act as stops and are engaged by a catch member 30 attached to a pivotally mounted rod 31 carrying a weight W which normally maintains the catch in the path of the stops. An arm 32 projecting from the rod rests on one end of a lever 36, the other end of which engages the lower end of the vertical shaft 40, supporting the severing device 41. When the tape is withdrawn, the disc 28 is rotated by the roll 22 until one of the stops x, y or z engages the catch 30, whereupon the spring 27 mounted in the recess 22a is pressed rearwardly by the pin 28a. The length of tape withdrawn is then severed manually and consequential downward movement of the severing device 41 rocks the lever 36 to disengage the catch 30 from the stop. The spring 27 causes the disc 28 to rotate and position the stop beyond the catch and to permit another length of tape to be withdrawn. The rod 36 may also be moved longitudinally, to position the catch member so that it engages alternate or only two of the ridge stops, and to be positioned so that the catch is held out of engagement with the stops. Such adjustment of the rod 36 enables different lengths or a continuous strip of tape to be withdrawn. The end of the tape is positioned after severing by its adherence to a shelf 41a on the back of the severing device.
