IPC: B21B27/10
Filed: 1960-04-11
Abstract: 912,048. Rolling. PROPERZI, I. April 11, 1960 [April 11, 1959], No. 12865/60. Class 83 (4). In a mill for the continuous rolling of bars and wires having three rolls 1 enclosing the work, the rolls 1 are journalled in walls which define an enclosure 11 within which the rolls rotate and also define with the main housing 4 chambers 12 which accommodate drive gearing 8, 9 and the driving shaft 2. Cooling and lubricating liquid is passed through the enclosure 11 via an inlet port 18 and an outlet port 19, ring seals 10 preventing escape of the liquid to the roll bearings which together with the drive gearing and housing parts are cooled and lubricated by a separate supply circulating in the chambers 12. Coolant is admitted to the lower chamber 12 through a port 16 and reaches the upper chambers via bores 17 in the lower roll shafts 5 to be discharged at ports 20. The removable cages for the lower rolls are held in position by bolts 15 which force the cages against shims 14 to effect a seal. Specification 714,737 is referred to.

Filed: 1922-05-08
Abstract: 202,014. Sandys, M. T. May 8, 1922. Barometers.-In an instrument provided with an altitude scale arranged to be read against a pressure scale, an index is provided which co-operates with both scales and is capable of be. ing set manually relatively to the altitude scale. In the form shown in Figs. 1 and 2, a pressure-actuated needle 19 moves over a pressure scale on a fixed dial 7. The altitude scale 8 is secured to a ring 10 moving on ball bearings 11, which ring may be clamped by a locking-ring 14. The index 9 is mounted between rings 15, 16, and may be clamped by a ring 17 which screws over the ring 10. In use, the index 9 is adjusted to the known height of the instrument on the altitude scale, and clamped to the scale. The latter is then moved relatively to the disc 7 until the index registers with the pressure needle. The pressure at the sea-level or any other height may then be read on the pressure scale opposite the required height indication on the altitude scale. The index 9 may be provided with a second index moving over a scale on the index 9 to compensate for known errors in the instrument. In a modification, the index 9 is fixed to the casing and reads against a manually-adjustable altitude scale and a pressure graduated and operated dial carried by the spindle of the instrument. In a second modification, the altitude scale is mounted on a disc on the spindle together with but adjustable relatively to the index which reads against the altitude scale and also a fixed pressure scale.

Title: Method of making a thermoplastic article
IPC: B29C51/30
Filed: 1959-04-17
Abstract: 906,597. Moulding thermoplastic sheet material. HEDWIN CORPORATION. April 17, 1959 [Dec. 12, 1957], No. 13131/59. Class 87(2). An article such as a hollow liner for a barrel is produced from a thermoplastic material e.g. polythene, with selected strengthened areas by heating a polythene sheet to a forming temperature, gripping the sheet at spaced positions and cooling the gripped portions to below said forming temperature, cooling selected portions of the sheet which lie intermediate the gripped portions to below the forming temperature, stretching the sheet to effect a differential stretching of the cooled and uncooled portions of said sheet, and subsequently cooling the entire sheet while stretched to below said forming temperature. A male mould set comprises a head 11 supported on a plate 12, a base 13 supported by a piston rod 14 connected to the piston of a fluid pressure cylinder 15, and a series of movable discs 26, not shown in Fig. 5, which are arranged between the head 11 and the base 13. The mould set at room temperature is lowered centrally on to a heated sheet 24 of polythene in a frame 25 and the polythene is stretched to a position Y, Fig. 5. Vacuum is then applied to the head and base to draw the sheet from a position 24a to a position 24b and the thickness of the sheet is fixed at the areas contacting the head, the base, and the peripheries of the discs 26. A valve 19 is then manipulated and the base 13 is forced away from the head 11, Fig 4 (not shown) and the uncooled material stretched. The stretched material is then cooled and the base 13 retracted. The head 11 and base 13 may be water-cooled if necessary.

Patent GB-1433233-A (GB)
Title: Frequency sensitive switching circuits
IPC: H03H17/02
Filed: 1973-03-20
Abstract: 1433233 Intruder alarm WALTER KIDDE & CO Inc 20 March 1973 [27 March 1972] 13331/73 Heading G4N [Also in Divisions H3-H5] A frequency responsive circuit comprises: a source of A.C. analogue signal which is converted into a pulse signal with pulse width dependent on the time the analogue signal exceeds a reference level; a circuit receiving the pulses and storing the energy in them; a first detector responsive to pulses exceeding a predetermined width as determined by the energy level stored; and a second detector responsive to pulses exceeding a second predetermined width, greater than the first predetermined width. Input signals are converted to a rectangular pulse train which is applied to terminal 27. As long as the input pulse rate is sufficiently high the amplitude of the sawtooth voltage developed on capacitor 37e, say, is insufficient to reach the threshold of switch 91, and no pulses are produced at its output. If the frequency drops below a predetermined value, the amplitude of the sawtooth across 37e increases to above the. threshold of switch 91 and each input pulse produces a corresponding pulse at the output of switch 91. This basic circuit, Fig. 2 (not shown) may be considered as a "lowpass" arrangement, since an output is only produced if the input is below a predetermined frequency. A "high pass" arrangement may be made by the addition of a monostable circuit 53 comprising a PUT and a capacitor 61. If the input frequency is below the predetermined frequency the output from switch 91 causes capacitor 61 to be continually discharged so that input pulses fed from 27 to gate electrode G, cannot trigger the monostable 53 and no output is produced at 31. Above the critical frequency, switch 91 produces no output so that monostable 53 is enabled and produces an output pulse each time an input pulse occurs. The basic "highpass" arrangement is described with reference to Fig. 5 (not shown). According to the invention this basic arrangement is converted to a "band stop" arrangement by inclusion of a further section 28f, 94 which applies an inhibit signal to switch 91 below a second, lower, predetermined frequency, thus allowing the capacitor 61 to charge at lower frequencies. By inverting the polarities of the switch outputs a "bandpass" arrangement may be obtained Fig. 7 (not shown) and a "bandpass" and "bandstop" arrangement may be combined to give a pass band with a notch in it, Fig. 11 (not shown). The circuits are described as being used in an ultrasonic or microwave Doppler burglar alarm system to prevent false alarms due to frequencies not due to burglars, e.g. those caused by fluorescent lighting.
