Title: Elevator speed control apparatus
IPC: B66B1/28
Filed: 1976-10-29
Abstract: 1518235 Elevator speed-control MITSUBISHI DENKI KK 29 Oct 1976 [29 Oct 1975] 45182/76 Heading G3N The velocity of an elevator cage driven by a cage hoist drive motor is controlled. Generator 1 generates a required cage velocity signal which is computed on the basis of the distance to be travelled by the cage 12 to the floor at which it is to land, using a stored table in a ROM. Detector 2 gives the actual velocity of the cage in motion and the two velocities pass to comparator 5 whose output is passed to circuit 6 comprising two AND gates. Unit 3 determines the distance to be travelled by the cage, selects the necessary cage acceleration, and switches it according to call or other data received. Device 4 sets the acceleration from unit 3 and this passes, via an acceleration modifier 7 controlled by circuit 6, to unit 8 which integrates the signal to give a command velocity for the motor driver 9. The cage position is determined by detector 18, unit 11 integrates the command velocity to give distance travelled, and gain adjuster 10 ensures a smooth transition between two velocities. Positionvelocity converter 19 is used for final cage positioning. The circuitry of Fig. 2 is described in detail, Figs. 3-5 (not shown).

Abstract: 1,121,530. Valves. QUALITROL CORP. 27 Oct., 1965, No. 45421/65. Heading F2V. [Also in Division H1] A quick-acting pressure relief valve for tanks containing electrical apparatus, such as a transformer 16a (see Division H1) comprises a tubular valve base 13 sealingly secured around an opening 14 in the tank 16 and normally closed by a valve disc 41 and ring 51 separately biased by springs 39, 49 respectively, the valves 41, 51 and base 13 defining an annular chamber 59 normally partially sealed by gaskets 25, 27 seated in the base 13 but allowing slight leakage through a recess 60, and another gasket 55 secured to the upper surface of the disc 41. When a fault occurs in the apparatus 16a the pressure of the inert gas or air cushion in the space 45 above the oil 16b rises until it is sufficient to crack the seal at 25, whereupon the gas leaks into the chamber 59 causing the ring 51 to rise until the force of the outer spring 49 is no longer transmitted to the disc 41 which therefore accelerates rapidly upward and takes the outer ring 51 with it. Alternatively, the disc 41 and ring 51 may be replaced by a single member (41a) (Fig. 9, not shown). The valve is said to operate within a half-cycle from the occurrence of a fault or explosion within the tank. After the excess pressure is reduced, the springs return the valve assembly to its normal position. The valve parts which engage gaskets may be coated with a silicone lubricant and indication that the valve has operated may be given by a coloured rod 61, manually reset, or by a remote indicating device actuated by a switch (see Division H1) when the valve member 51 rises.

Abstract: 1,025,178. Light amplifiers; modulating light by light. WESTERN ELECTRIC CO. Inc. Dec. 4, 1962 [Dec. 11, 1961], No. 45723/62. Headings H3B and H3R. [Also in Division G2] Apparatus for generating harmonics, subharmonics or modulation products of electromagnetic radiation comprises a source 11 of coherent input electromagnetic radiation, a substantially non-linear, non-centrosymmetric, low-loss birefringent medium, such as a crystal 10 of potassium dihydrogen phosphate, so positioned that the input radiation travels in a direction along which the wave of polarization at a desired output frequency set up by the input radiation has a phase velocity substantially equal to that of an induced wave of the desired frequency. As shown, a ruby laser 11 supplies red light of wavelength 6,940 Angstroms to the crystal 10 cut so that the light makes an angle of 50 degrees with the optic axis Z and the projection of the ray on the XY plane makes an angle of 45 degrees with each of the X, Y axes. Ultra-violet light of wavelength 3,470 Angstroms is generated and passes out through filter 12 which eliminates the red light. The angle of cut, 50 degrees, is such that the velocity of the ordinary ray of the red light equals that of the extraordinary ray of the ultra-violet light. The crystal may be enclosed in a Fabry-Perot etalon 13A, 13B resonant at the frequency of the applied light. In a modulation arrangement, Fig. 3 (not shown), two sources 21, 22 are directed at the birefringent crystal 23 the direction each beam makes with the optic axis being such that the velocity of the wave of polarization P resulting in the crystal matches the velocity of a ray of the induced light of the desired modulation frequency along this direction, either the sum or difference modulation product being selected as the desired output frequency. As applied to parametric amplification, Fig. 4 (not shown) a laser beam 31 acting as the pump and a signal source 32, supply beams to the crystal 30 preferably, but not necessarily, in the same direction, the signal and idler beams being ordinary rays whose velocity is closely matched to that of the extraordinary ray of the pump. For parametric generation, Fig. 5 (not shown), the crystal 40 is irradiated with light from laser 41, reflective elements 42, 43 being provided on opposite sides of the crystal to form a cavity resonant at the desired frequencies.

Filed: 1971-10-05
Abstract: 1364301 Valves WATTS REGULATOR CO 5 Oct 1971 [5 Oct 1970] 46348/71 Heading F2V A control valve assembly for preventing contamination by backflow in water supply systems, comprises an intermediate chamber 46, a main inlet 44, a main outlet 50, and a relief chamber 48 communicating with atmosphere via outlet 28. When there is a demand for water, the pressure differential across a flexible member 52 exceeds a predetermined value, e.g. 2 p.s.i.g., and causes the outer region of the member 52 to move away from annular seat 14a and thereby permit water to flow from inlet 44 through the intermediate chamber 46 and a valve 75 to outlet 50. When there is no demand, the consequent fall in the pressure differential causes the member 52 to assume the closed position shown. If however the pressure differential is caused to fall still further, e.g. due to malfunctioning of valve 75 permitting backflow into chamber 46, the centre portion of the member 52 is raised off a central annular seat, and a connected valve member 66 is raised clear of its cylindrical seat 38a by a spring 74, thereby communicating the the chamber 46 with the relief chamber 48.
