Title: Improvements in and relating to regulators operated by periodically acting auxiliary power
IPC: H05B7/156
Filed: 1923-07-10
Abstract: 222,950. Roucka, E. July 10, 1923. Drawings to Specification. Valves controlled by pilot or relay valves.-In a device for regulating velocities of fluid flow or liquid levels, a lever sensitive to the value to be regulated operates, through the intermediary of a periodically-acting auxiliary power, the controlling-device of a servomotor which restores the value to its predetermined normal condition. In order to maintain a constant velocity of fluid flow through a pipe, differences of pressure on each side of a throttling device in the pipe and consequent upon a variation of velocity act on the sensitive lever to effect a regulation of the throlling device by the servomotor. When the apparatus is used for regulating liquid levels, a float acts on the lever and the servomotor regulates the inflow and outflow of the liquid by means of a valve. Specification 223,284, [Class 40 (i), Electric signalling systems &c.], is referred to.

Title: Improvements relating to torque-balancing arrangements
Inventor: BAXTER PHILIP
IPC: G01L3/10
Filed: 1961-05-17
Abstract: 935,915. Electric bridge circuits. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. April 18, 1962 [May 17, 1961], No. 17996/61. Class 37. [Also in Group XL (b)] The invention relates to torque-balancing arrangements for deriving, such as for torque measuring purposes, electrical outputs dependent upon the torque applied to a shaft, and particularly to arrangements in which the shaft torque is balanced electromagnetically. In the embodiment shown, a torque applied to a shaft 1 is opposed by torque exerted on the shaft in response to a flow of current through a coil 2 carried by the shaft and associated with electro magnetic means (not shown), the coil being connected in series with the operating coil 3 of a torque measuring device (not shown) and across the output terminals of a bridge circuit comprising two photo-sensitive cells 5, 6 and resistors 7, 8, the input terminals being supplied with A.C. or D.C. A suitably slotted or apertured disc 9 secured to the shaft 1 controls the light reaching the cells 5, 6, from a lamp 10 on rotation of the shaft, thereby increasing or reducing the current flowing through the coils 2, 3 until the electromagnetic force acting on the shaft balances the applied torque. One of the cells may be arranged to be fully energized while the other is completely de-energized. Furthermore one of the cells may be replaced by a suitable impedance. The balancing torque may be applied to the shaft by securing a further coil to the shaft and by suitable selection of the turns ratio between this coil and coil 2, the arrangement can serve as an amplifier, with the amplified signal dependent on the signal applied to the additional coil being derived from the current flowing through the coil 2 under balance conditions.

Title: Electronic frequency meter
IPC: G01R23/02
Filed: 1963-05-07
Abstract: 1,025,803. Frequency detectors. COMPAGNIE INDUSTRIELLE DES TELECOMMUNICATIONS. May 7, 1963 [Sept. 21, 1962], No. 18070/63. Heading H3A. [Also in Division G4] In a digital frequency meter employing a counter and using a D.C. voltmeter as an output indicator an " expanded scale " is obtained by controlling the voltmeter from the lower denominational stages of the counter, the higher stages being used merely to decide upon the range in which the frequency lies. The arrangement described is particularly adapted for measuring A.C. mains supply frequency, which should not depart by more than 2 c/s. from its nominal frequency of 50 c/s. The frequency is measured by counting the clock pulses from a 73À5 kc/s. source that occur in one cycle of the mains voltage. A frequency range of 52 to 48 c/s. then corresponds to a count range of 1413 to 1531. Now with an eleven-stage binary counter a range of 10110000000 to 10111111111 (i.e. from 1408 to 1535), over which the top four denominations remain constant at 1011 and the bottom seven denominations vary from 0000000 to 1111111, corresponds to a range of 52À2 to 47À9 c/s. Also even though the count varies inversely with the mains frequency over this small range the count varies substantially linearly with the frequency. Thus, in the arrangement described, if the count, at the end of a mains cycle, lies in the range 1408 to 1535 the count in the bottom seven denominations is displayed by converting the inverse of the count (to avoid a reverse reading scale) to a corresponding voltage which is indicated on a voltmeter, graduated, as shown in Fig. 3, linearly from 48 to 52 c/s. If, however, the count is not in the range 1408 to 1535 then the voltmeter is so controlled as to indicate either zero or a full scale deflection, that is the actual count in the bottom seven denominations is ignored. A block diagram is shown in Fig. 1 and it comprises a first gate 13 which is opened by a trigger 14 under control of a main timer 16 to pass the squared mains voltage to a trigger 26 which opens a counting gate 21 for one cycle of the mains voltage to allow the relatively high frequency clock pulses from a source 22 to pass to the counter III, the inverse outputs of the bottom seven denominations of which control a digital-to-analogue converter 29 and voltmeter 30. At the end of the counting period, when trigger 26 closes gate 21, it also resets trigger 14 via OR gate 27 and hence closes gate 13. If, by the end of the counting period, the count has not exceeded the lower end of the range, namely 10110000000, then a trigger 24, which is also turned on at the beginning of a measurement period by the timer 16, will not have been turned off, so that a pulse will pass via gates 25 and 17 and delay 18 to zeroize the counter and hence cause a full scale deflection on the voltmeter. If during the counting period the count reaches the upper end of the range, namely 10111111111, that a gate 19 closes the counting gate 21 and a zero deflection is produced on the meter.

Abstract: 581,630. Collar supports. WEINER, B. Sept. 22, 1944, No. 18158. [Class 141] A support for the wings of soft collars of the type having two telescopic limbs connected by a resilient wire member adapted to fit behind the tie, has each of the limbs formed from two leg parts connected by a helical spring enclosed within a sheath. As shown, the central member 1 is shaped to form loops 2 each leading into an upper leg part 3 which is enlarged at 5 and secured in axial alignment with a light helical spring 4. Each lower leg part 6 is similarly secured to the spring 4 and has a pointed end provided with a loop 8 to limit the penetration into the fabric of the collar. The spring 4 is free to slide in a rigid sheath 7 fixed to the upper leg part 3 and from which the lower leg part 6 projects. The central part 1 may, if desired, be looped to engage the collar stud. In a modification, the spring may be formed integrally with the leg parts. In another modification, the sheath may be fixed to the lower leg part instead of the upper or it may be made integrally with one of these parts by coiling the latter.

Title: Improvements in the production of castings and ingots
Inventor: HUME ROLAND DUDLEY
IPC: B22D7/10
Filed: 1960-05-23
Abstract: A method for the production of ingots and castings comprises locating in the mould or the head-box or riser thereof an exothermic product consisting of a major portion of a composition which is not directly ignitable in contact with the molten metal but which retains its shape when burnt out, in association with a minor proportion of exothermic material having much greater sensitivity to ignition. Both compositions may consist of aluminium, an oxidising agent, fluoride and a filler, the greater sensitivity being obtained by variation of composition or by use of very finely divided aluminium, or the more sensitive material may be a readily oxidisable substance such as magnesium or silicon.  The more sensitive material may be present as a layer on a preformed body of the major constituent, or as inserts therein. For example wire, cord or tube, e.g. of woven synthetic fibre may be coated by immersion in a slurry of the more sensitive material, placed in position and the less sensitive material rammed round it.  When surface finish of the insert is important the major constituent may be faced with an inert, metal-impermeable material, plugs of sensitive material being located in that surface and extending through to the less sensitive backing. Specifications 627,678, 769,719, 772,273, 774,490, 774,491, 775,380, 785,984 and 805,823 are referred to.
