Title: Improvements relating to tape-reading apparatus
Inventor: POLLARD BRIAN WATSON
IPC: H04L17/14
Filed: 1951-02-27
Abstract: 711,482. Statistical-apparatus. FERRANTI, Ltd. May 7, 1952 [Feb. 27, 1951], No. 4717/51. Class 106 (1). [Also in Group XL(b)] A tape bears both intelligence and control markings and is frictionally driven past a reading device, the control marking producing a signal which arrests the tape, allows the intelligence markings to be translated into signals and finally re-starts the feeding of the tape. The invention is described with reference to an apertured tape co-operating with photo-electric cells, but the apertures may be transparent areas, and the invention is equally applicable to magnetic recording. In Fig. 1, the tape 17 is fed by friction through rollers 16, 18 driven from a continuously running motor 15 through a differential gear 12 which drives shafts 13, 14 ; when a control marking 31 affects its appropriate photo-cell, the resulting signal is shaped at 42, Fig. 4, and applied to a stable trigger circuit 44 to energize brake 19 and de-energize brake 20 so that the tape is arrested , the output is also applied to the reading device 50 from which is finally derived a pulse for restoring the trigger device 44 to energize brake 20 and release brake 19 and thus restart the tape feed. To omit any intelligence marking, the control marking is either covered up or extended to connect with the previous control marking. The trigger circuit 44 is coupled to the brakes 19, 20 over an amplifier 47 or 49 which preferably comprises a pentode valve 80, Fig. 5, normally cut-off so that condenser 82 is charged to the potential of HT+ ; when the control signal is applied to 48, the pentode conducts so that the full potential of condenser 18 is immediately applied to the brake energizing windings 27. A further condenser 85 may be connected as shown to prevent bounce or chatter of the brake when released. Two-speed operation.-To reach a desired part of the tape quickly, the arrangement of Fig. 6 is used ; motor 15 runs at a comparatively slow speed while motor 94 runs at a comparatively high speed ; with brake 93 operated, the speeds are additive so that shaft 13 is rotated at high speed; if brake 21 is operated, shaft 13 is driven only at the speed of motor 15. Reversible feed.-If this is required, the arrangement of Fig. 7 may be employed; motor 15 drives shaft 13 through differential gear 12 whose shaft 14 can be stopped by brake 21 and whose shaft 13 is coupled over brake 21<SP>1</SP> to shaft 100 of a gear 101 driven by motor 104 and whose shaft 102 can be stopped by brake 103: for forward feed, drum 21 is braked, but for backward feed brake 103 is applied ; the tape is stopped by applying brake 21<SP>1</SP>. The Specification also envisages the combination of Figs. 6 and 7.

Abstract: 588,514. Manure distributers. BAMFORD, C. J., and BAMFORD, H. V. Feb. 26, 1945, No. 4720. [Class 6 (i)] In a manure-distributing machine in which a conveyer feeds manure to a rotary beater, the chain drive from the land wheels to the beater passes over sprockets mounted on a pivoted bell-crank lever which is made in two parts slidably movable relatively to one another against the pressure of a spring. In the form shown, the bell-crank lever is pivoted on a pin 11 projecting laterally from the machine, which pin.also carries a sprocket 13. One of the arms 14 of the lever is attached to a pull-rod 16, the other arm 10 being bent into U-shape. A further U-shaped member 22, carrying at its lower end a sprocket 24, is pivotally mounted on the pin 11 and is provided with longitudinal slots 23 which enable it to slide longitudinally in relation to the arm 10. A compression spring 27 is provided to operate between a cross bar 26 on the member 22 and the end of the arm 10. A driving chain 25 entrains the sprockets 13 and 24, and, in one position of the lever, engages the periphery of a driving sprocket 8. By the operation of a hand lever (not shown) attached to a pull-rod 16, the bell-crank lever may be rotated about the pin 11 into a position where the chain 25 does not engage the driving sprocket. The disposition of the levers is such that the system is self-retaining in either of its two positions.

Abstract: 885,387. Typewriters &c. INTERNATIONAL BUSINESS MACHINES CORPORATION. Feb. 10, 1960 [Feb. 24, 1959], No. 4723/60. Class 100(4) A variable line spacing mechanism is operated by a hydraulic motor and controlled by a start electrical pulse which through appropriate delay circuitry produces a stop pulse after the desired number of line spacings had been effected. A hydraulic motor 73, which is supplied from fluid pressure generating means 74 rotates the shaft 71 mounting a platen 70 to feed paper forms 72 under the control of valve control means 75. A pair of spool valves 76, 77 control line spacing and paper ejection respectively. An electrical line spacing start pulse operates a start magnet LSSTM which moves the valve 76 to the left thus opening a chamber 82 to the central exhaust port 83 to allow the motor 73 to operate to effect line spacing. The start pulse is also applied to a suitable delay circuit, which may include a single shot multivibrator and an inverter, and which after a preselected variable delay generates a stop pulse which is applied to a stop magnet LSSPM which restores the valve 76 to stop the paper feed after the selected number of line spacing have been effected. Specification 819,465 is referred to.

Title: Improvements in or relating to electroacoustic transducer
IPC: B06B1/06
Filed: 1945-02-26
Abstract: 604,358. Electro-acoustic transducers. SUBMARINE SIGNAL CO. Feb. 26, 1945, No. 4824. Convention date, Dec. 19, 1939. [Class 40 (iv)] [Also in Group XXXVIII] A submarine transducer comprises a prismatic structure having a plurality of transducer elements such as crystals mounted on its faces and a cover member freely transmitting acoustic vibrations, the intervening space being filled with wave-conducting liquid. The quarterwave crystals preferably of Rochelle salt are mounted in pairs on the vertical faces of a hollow hexagonal prism 4, Figs. 1 and 2, in two or more rows 8 and 8<SP>1</SP> and are separated by insulators 9 of thickness small compared with the signal wavelength in water. Crystals of each pair are connected in series and the several pairs are preferably connected in seriesparallel. The sides of the prism have length .89 times the wavelength in water which is said to ensure full coverage in all directions. For transmission in a vertical direction one or more rows of crystals 10 are mounted on the top plate 7 of the prism. The sides and top of the hexagon have thicknesses # of the wavelength in its material which is said to reflect back all the energy received from the crystals. The top plate 7 is separated by a thinner portion 6 from the sides of the hexagon. The cover 12 which is of quarter-wavelength thickness and acts as a diaphragm approaches as closely as possible to the crystals and is secured to the base 1 by screws 14 in the groove 13, a water-tight gasket 15 being interposed. The material of the diaphragm has a specific acoustic impedance substantially the geometric mean of those of the impedances of the crystal and the outer water, and may be of a moulded macerated substance such as is known under the Registered Trade Mark " Bakelite." The space between the cover and the hexagon is filled with a waveconducting liquid such as castor oil. If larger power is required and hence it is necessary to have more crystals, the beam from each group will be narrower and therefore the prism must have more sides in order to ensure uniform radiation in the horizontal plane. If uniform hemispherical radiation is required, the upper surface must be replaced by a number of angularly disposed surfaces. The device may be used for telephone communication. Further, leads from each group of crystals may be brought out separately so that by utilizing one set at a time the general direction of the transmitting source may be found and also disturbances arriving in other directions eliminated. Quarter-wave magnetostrictive elements may be employed instead of piezo-electric elements.
