Title: Improvements in machines for producing perforations, weakening lines and the like in paper, pasteboards or the like
IPC: B26F1/26
Filed: 1962-02-12
Abstract: 931,130. Perforating apparatus. G. S. HELLBERG. Feb. 12, 1962 [Feb. 16, 1961], No. 5332/62. Class 31 (2). A machine for producing perforations or weakening lines in paper, pasteboard or the like by means of a patrix 4 co-operating with a rotating tool 8 comprises means to control the temperature of the working surfaces of either or both of these members for the purpose of adjusting and maintaining a requisite clearance between them. The tool comprises cutters in the form of ribs 9 on the periphery of a roller arranged to rotate at a far greater speed than the patrix 4 which is in the form of a roller provided with protuberances or pegs 6 having outer surfaces corresponding to the shape of the holes to be perforated in the web 2 to be cut. The desired clearance between the patrix and tool is first set by adjustment of the tool and then maintained, in the example shown, as heat develops in the patrix and tool, by supplying a jet of air to the surface of the patrix through a conduit 15. The air supplied through the conduit is treated in a temperature-controlling device 18 and also receives an injection of moisture in the form of mist from a device 20. If desired, the temperature-controlling device 18 may be omitted and in another arrangement use may be made of refrigerating means for controlling the working surface instead of using an air jet. Similar temperature-controlling means may be provided in connection with the tool 8. The invention is described in relation to a process in which, when perforating resincontaining paper, a resinous deposit is formed on the working surfaces of the tool and patrix. Specification 886,484 is referred to.

Abstract: 983,077. Friction gearing. VECTRON ELECTRO-PHYSICS Ltd. Feb. 13, 1963 [Feb. 13, 1962], No. 5407/62. Heading F2Q. [Also in Division G5] Idler-rollers 10, engaging reversible frictiondrive means 9 and flywheels 8 carrying capstans 4, which with pinch-rollers 5 are simultaneously engaged to drive a record tape on other elongate medium 1 in the same direction, have their axes laterally offset differentially with respect to the lines joining the axes of the members 8 and 9. With the directions as arrowed, the resulting increased nip of 10b and reduced nip of 10a would, in the absence of the tape 1, result in a ¢% speed differential in the capstans 4, where the drive means 9 are synchronized but with the capstans coupled by the tape, the differential torque provides sufficient tape tension between the capstans to dispense with the usual pressure pads where the tape passes over transducer means 2, 3. Idler roller-arms 13 are preferably pivoted on axes on the lines joining the axes of the members 8 and 9 and when the drive is broken (by means not detailed) by disengaging the idlerrollers 10, ears 14 prevent casual, unwanted contacts of the idlers by limiting the movements of links 11.

Title: Improvements relating to variable-frequency oscillators
Inventor: GOODALL LAURENCE
IPC: H04L27/12
Filed: 1969-02-01
Abstract: 1,237,204. Frequency modulation. FERRANTI Ltd. 23 Jan., 1970 [1 Feb., 1969], No. 5558/69. Heading H3R. A variable frequency oscillator comprises: a tuned circuit LC which includes a switch T3 ... T6 having a first state in which the tuned Circuit is completed, and a second state in which the tuned circuit is interrupted; and a switch control circuit operable in response to a control signal at X either to maintain the switch in one state, or to cause it to alternate between the two states at a frequency considerably greater than the resonant frequency of the tuned circuit. The oscillator is used for transmitting FSK telegraphy signals, the signal at X being a two-state signal corresponding to "0" or "1". In one state the signal X opens a diode gate D3, D5, D6 to connect a multivibrator M to switch switches T3 ... T6 between their two states, thus alternately connecting and disconnecting capacitor C and inductor L to form a resonant circuit. In the other state of signal X the diode gate is closed and transistors T5, T6 of the switch remain conductive to close the LC circuit. In the state in which the switch is alternately opened and closed, the frequency of oscillation depends on the mark/space ratio of the multivibrator signal. Fig. 3 (not shown) discloses an alternative arrangement of the switches to permit one side of capacitor C to be connected to earth.
