Abstract: 927,564. Doctors for paper-making machines. H. E. B. SCOTT. Oet. 24,1961 [Nov. 21, 1960], No. 39949/60. Class 96. [Also in Group XVI] A doctor for a paper-making machine having on its carrier 15 a suction chamber 16 for applying suction to the blade 18 along its length and near its tip to remove dust &c. from the associated roll, includes means, should the web break, for moving the chamber relatively to the carrier 15 from its working position to one in which the chamber acts to guide the tail of the broken web into the following nip. The carrier is pivoted at 35 and the suction chamber at 19. When a break recurs, the tail is drawn into the space between the chamber and the carrier and operates one of two microswitches MS 1 , MS 2  to close a circuit (which is described) controlling a valve whereby (a) compressed air is supplied to a pair of cylinders C 1  to pivot the chamber to the second position shown where its face 23 acts to guide the tail (b) suction is cut off from the chamber 16, (c) compressed air is admitted to a nozzled pipe 20 to help direct the tail, and (d) compressed air is admitted to a second pair of cylinders C 2  to apply the blade with increased force against the associate roll to compensate for the change in pressure resulting from the movement of the chamber. The parts can be restored by manually operating a button switch and hand-operated switches are provided for admitting air to cylinders C 2  to raise the doctor off the roll. In another form, the cylinders C 2  are omitted and cylinders C 1  raise the chamber 16 through intermeshing gears, the arrangement permitting the application of increased pressure to the doctor when the chamber is raised. The mechanism can also shut off suction to any chambers fitted to doctors on adjoining top rolls, and give an audible or other signal that a break has occurred.

Title: Improvements in or relating to apparatus for supplying an electric timing signal under the control of an input electric signal
IPC: H03L7/191
Filed: 1961-11-08
Abstract: 982,327. Automatic plane control. GENERAL ELECTRIC CO. Ltd., and J. M. SMART. Nov. 8, 1962 [Nov. 8, 1961], No. 39998/61. Heading H3A. In a signalling system, e.g. a telemetering system in which a signal is transmitted which at each of a succession of equal intervals of time has one or other of two values, means are provided at a receiving station for producing a timing signal from the received signal for synchronizing the operation of the receiving station equipment. The intervals of time have a duration of 20 m.secs. and the received signal, appearing at terminals 37, 38, is applied via bi-stable circuit 36 to bi-stable circuit 41 which produces a short duration signal for priming bi-stable circuit 44 whenever a transition occurs in the value of the received signal. An oscillator 31 operating at either 598 or 602 c/s., i.e. nominally twelve times the recurrence frequency of the received signals supplies an output via squarer 33 to a twelve-stage circulating register 32 arranged such that at any time only one of its stages registers " 1 " while all remaining stages register " 0." Stages 4-7 of the register are connected to one input of bistable circuit 44 via gate 45 and stages 9-12 are connected to a second input via gate 46. The preferred times of occurrence of transitions in the received signal are when stage 8 of the register stores the value 1, if, however, oscillator 31 is operating at its lower frequency a time will be reached when a transition occurs when one of stages 4-7 registers " 1 " and a signal is applied via gate 45 to bistable circuit 44 when the circuit is primed by the transition signal. On switching the circuit produces an output which switches the oscillator to its higher frequency. Operation at the higher frequency eventually produces coincidence between a transition and the storing of a " 1 " in stages 9-12 when the oscillator is switched back to its low frequency via circuit 44. As each stage of the register stores " 1 " once every 20 m.secs. time signals for synchronizing the receiver equipment are obtained from leads 49-54. The oscillator, Fig. 1 (not shown), includes a transistor circuit which switches a small capacitor in parallel with the oscillator tuned circuit for lowfrequency operation. Specification 982,326 is referred to.

Title: Improvements in or relating to Tuning Units.
IPC: H03J1/06
Filed: 1967-09-01
Abstract: 1,195,910. Push-button tuners. BLAUPUNKT-WERKE G.m.b.H. 1 Sept., 1967 [3 Sept., 1966; 22 Sept., 1966], No. 40062/67. Heading H3Q. In a push-button tuner wherein tuning is effected by altering the voltage on a varicap diode with adjustable voltage dividers, operation of a button (a) causes a gear-wheel on the button spindle which meshes with a gear on the parallel spindle of the corresponding voltage divider, to be clutched to a central spindle; (b) causes a cam to close a switch to bring the corresponding voltage divider into circuit; and (c) adjusts a tuning indicator by means of a swivel lever operated by an adjustable limit stop on a threaded portion of the button spindle. In Fig. 3 a gear 40 (of insulating material) engages a gear 44 on the spindle 45 which carries the slider 71 of a variable resistance, and, when a button 12 is pressed, a shoulder 43 presses a spring contact 47 upwards to complete the circuit. At the same time a bar 49 on the portion 48 of the button spindle slides in a slot 50 and moves a swivel arm 81. This carries a tension wire 83 (Fig. 1) which unwinds from a roller 84 on the shaft of the cylindrical tuning indicator 20 and turns it by the appropriate amount. Fine tuning.-Each button spindle carries a second gear 53 normally free but which is clutched to the spindle when the button is pressed by a pin 52 engaging crossed slots in a shoulder on the gear. A fine tuning knob 21 drives the gears 53 on all the button spindles through gears 64 and 65, but only the spindle which is clutched in will be rotated by the knob 21. The slider 71 of the voltage divider associated with this spindle will then be moved through gears 40 and 44 and threaded rod 45. At the same time the threaded portion 48 of the button spindle will cause the stop 49 to move to ensure that the correct tuning indication is displayed corresponding to the position of the slider 71. Band-change switch.-On the side of each button are three pairs of strips 15 which cooperate with tags 16 on the frame of the tuner, allowing the button to be set in one of three angular positions. At the rear of the button a disc 28 (Fig. 3) carries three projections 29, 30, 31 of unequal extent, and one of these engages a rocker 33 linked to a disc 34 (Fig. 1) at the top of the unit. This disc has a three-stepped slot 36 which engages a pin on a slide 37 to operate the band-change switch.
