Title: Improvements in hygrometric elements
Inventor: CLIFF THOMAS CHARLES
IPC: G01N19/10
Filed: 1964-10-21
Abstract: 1,074,335. Hygrometric elements. BRITISH THERMOSTAT CO., Ltd. Jan. 20, 1966 [Oct. 21, 1964], No.42894/64. Heading G1S. A hygrometric element comprises a sheet or strip of animal skin, paper, hair, plastic or like material which changes its physical dimension with changes in humidity the strip being treated with a salt such as lithium chloride having a large change in water content for a relatively small change of ambient humidity. The salts may be applied by immersion or spraying to give a large change in dimension per percentage change in humidity. Other examples of a salt used are sodium chloride and ammonium chloride. The hygroscopic salt may be mixed with a binder such as gelatine or polyvinyl alcohol so that the salt remains in the element even when the humidity is high.

A casement stay comprises a hollow stay bar 18 having a guide slot 19, and an elongated fastening plate 10, having at least one upstanding flange 11 at one end and an upstanding guide peg 13 remote from the flange and captively and slidably engaged in the slot, the stay bar having means such as a yoke 27 whereby it can be pivotally secured to a casement 30 and the fastening plate being adapted to be secured to a window frame 16 so that, in use, the stay bar cannot be disengaged from the peg and the flange can be used to retain the bar in a position overlying and aligned with the plate. The peg comprises a shank 14 extending through the slot 19 and a larger diameter boss 15 which can engage holes 22 in the top of the bar to hold the casement open but cannot be separated from the bar except through an enlarged aperture 33 (not shown) at one end of the slot. This aperture lies outside the nomal range of movement of the peg in the slot, so that the bar can only be separated from the plate by unscrewing one or other from the window. When the casement is closed the bar is located between the two flanges 11; if only one flange is provided it is positioned either on the side of the bar remote from the casement or midway across the plate so that it engages in the guide slot.

Abstract: 958,185. Electromagnetic switches. STANDARD TELEPHONES & CABLES Ltd. Nov. 22, 1962 [Nov. 22, 1961], No. 44205/62. Heading H2B. A sealed magnetic contact device comprises a bifurcated change-over magnetic contact blade 4 both forks 5, 6 of which normally engage a fixed non-magnetic contact 2. The upper surface 8 of fork 6 and the lower surface 7 of fork 5 are coated with one of the precious metals, gold or silver. When the device is energized, the fork 6 is attracted to a fixed magnetic contact 3 while the other fork is still in engagement with the non-magnetic contact 2. When the device is sufficiently energized, the other fork 5 is attracted to the magnetic contact 3 as well. On de-energization, fork 5 engages contact 2 before fork 6. In an alternative embodiment (Fig. 3, not shown), one fork is uncoated and the other is coated on both sides with precious metal. On energization the coated fork engages the magnetic contact before the uncoated fork and on deenergization leaves the magnetic contact before the other one. The device may be energized electromagnetically or by the approach of a permanent magnet.

A thyratron comprising a cathode 41, an anode 38, and a control electrode 39 provided with at least one narrow aperture through which the discharge passes in operation, also includes an additional electrode 42 provided with apertures corresponding to each aperture in the control electrode and of the same shape and size and at least approximately in register in the discharge path. The additional electrode 42 acts as a dummy anode and is connected to the anode by a high resistance (not shown). When the valve conducts the dummy anode has no effect, but when it is non-conducting the dummy anode is at the same potential as the anode and the apertures in it are sufficiently small for the electric field on the cathode side of it to be unaffected by the shape of the surface of the anode 38 so that performance is not affected by erosion of the anode surface by the discharge. In the arrangement shown the anode is the main anode, but it may alternatively be an auxiliary anode of the device. The electrodes 39 and 42 may each be provided with a single cross-shaped aperture (Fig. 2, not shown). The anode 38 is supported from a cylinder 35 joined to a ceramic ring 33, and the dummy anode 42 is supported by a tubular member 31 sealed to a ceramic cylinder 26 joined at its other end to a conductive cylinder 2 carrying the control electrode 39. The cylinder 2 is joined by ceramic members 7-9 to a cylinder 1, the joints being shielded by a tubular member 13 near which a baffle 40 is arranged.

Filed: 1971-10-06
Abstract: 1353495 Automatic control systems EATON CORP 6 Oct 1971 [26 Oct 1970] 46453/71 Heading G3R [Also in Division F2] The speed of a rotational drive is regulated by controlling the energization of a winding in an electro-magnetic coupling. The supply to the winding is automatically controlled by variation of the firing angle of a triggered semiconductor device in response to feedback representing speed, winding current and rate of change of current. As shown, a load 13 is coupled to an SCR power supply 15 through an eddy current clutch 11. The supply to the clutch winding is controlled by varying the SCR firing angles using pulses from a generator 19 controlled in turn by the output of an integrated circuit differential amplifier 21 which receives a reference voltage input and feedback signals from an A.C. or D.C. tachogenerator driven by the load 13. Winding current and rate of change of current signals are also fed back to the amplifier 21, the rate of change circuit comprising a bandpass filter. The reference voltage represents a desired angular velocity of the load. A circuit 37 limits the phase of the SCR firing angle in order to prevent excessive current in the winding. The reference voltage supply 31 may be connected to the amplifier 21 through a circuit which produces an output increasing linearly or logarithmically to the set value. The pulse generator 19 includes logic circuitry and a ramp voltage generator, and inverting pulses are supplied to the SCR circuit at the end of each half-cycle to allow rapid decay of the winding current. A brake winding is automatically energized when the clutch supply is switched off. The arrangement may be used for regulating the tension of a paper web in a printing press, a feed or takeup roller being driven under the control of a feedback signal derived from the position of a dancer roll around which a loop of the web is passed.
