Title: Improvements in permutation locks
IPC: E05B37/00
Filed: 1920-08-19
Abstract: 171,768. Elcock, R. Aug. 19, 1920. Guarding against unauthorized use.-The bolt of a permutation lock has to be disengaged from one of a series of gated rings, nested within each other, by being pushed forwards. before the rings can be set to allow the bolt to be withdrawn. Fig. 1 illustrates the lock applied to the steering- pillar of a motor-vehicle. The bolt 13 slides in the hollow screw 4 and the dial plate 11, mounted in a seating 3 secured to the steering-column 1. Pivoted on the bolt is a projecting member 17, which prevents withdrawal of the bolt when obstructed by the rings 18, 26, 25. Each of these rings has a gate, and when set in a predetermined position, the member 17 can pass through them. The rings are mounted one within the other, the outer one 18 being fixed to, or integral with, the casing and projecting inwards beyond the edge of the other two, its projecting-edge having false gates 19 cut in it. The bolt is rotatable by means of the engagement of its square head 20 in a hole in the dial plate 11. To set the rings for releasing the bolt, the member 17 is disengaged from the notch 19 in which it is resting, by pressing the bolt in the locking direction. The dial plate 11 can then be rotated, a stud on it engaging a stud 31 on the ring 25, and a lug 32 on this engaging a stud 33 on the ring 26. Turning the plate 11 by a certain amount first in one direction and then in the other, sets the gates 28, 27 of the rings 26, 25 under that, 24, of the fixed ring 18, and a final turn of the plate brings the member 17 into position to pass through the gates, allowing the bolt to be withdrawn. The member 17 can tilt forwards, enabling the bolt to be shot in any position of the rings. Its shoulder 40 engages a recess in the flange 39 of the bolt to resist pressure in the unlocking direction. Fig. IV shows a modification in which the bolt is non-rotatable and the outer ring 18 rotatable. In this case, the ring 25 is made fast to the dial plate 11 so that the rings are set in the same manner as before.

Title: Improvements in or relating to sealing systems
Inventor: STEVENS RAYMOND KENNETH PETER
IPC: F28D19/04
Filed: 1949-09-20
Abstract: 687,103. Sealing systems in particular for rotary regenerative heat-exchangers. POWER JETS (RESEARCH & DEVELOPMENT), Ltd. Sept. 1, 1950 [Sept. 20, 1949], No. 24200/49. Class 64 (i) Relates to arrangements, for example in rotary regenerative heat exchangers, for forming seal between a dividing wall 3, separating adjacent high and low pressure fluid chambers A, B, and a face of a member (e.g. a rotary matrix 1) moving across the wall, said seal comprising a sealing element 4 slidable against the face of the movable member for preventing fluid leakage across the seal between the chambers A, B and in sliding engagement with the wall 3 to minimise fluid leakage between the sliding surfaces 5, 6 of the element and the wall, such leakage tending to act on the element and to overload it and urge it hard against the face of the movable member. According to the invention, the sealing element is provided with a loading device tending to urge it into controlled sealing engagement with the face of the movable member whilst opposing any overloading urge due to fluid leakage (viz. between the sliding surfaces of the sealing member and the wall). In the form shown each element 4 of the seal fixed is to one end of a bellows 14 by means of a rigid tubular member 22, the other end of said bellows being secured through a dished member 17 to the wall 3 separating the chambers A, B. The dished member 17 forms with an end plate 18 an enclosed space containing the bellows, said space communicating with the rear face 13 of the sealing member 4 by way of a passage formed through a spigot 21 on the wall 3. The effective area of the movable end 15 of the bellows is made substantially the same as that of the rear face 13 of the sealing element 4. In operation the seal 4 is maintained in sealing contact against the face of the matrix 1 by the bellows 14 actuated by pressure fluid bled solely from a selected part of the rubbing face 12 of the seal and directed to the interior of the bellows through a bleed duct 11, any pressure applied to the rear face 13 of the seal by fluid leakage between the surfaces 5, 6, which would tend to increase the sealing pressure at the maxtrix face being counterbalanced by a corresponding pressure in the opposite direction on the end 15 of the bellows. A plurality 6f elements extend across the matrix face each element having its own bellows. Leakage between adjacent elements 4 is prevented by tongue and groove seals and by dumb-bell shaped parts interconnecting adjacent sealing elements Figs. 2 and 3 (not shown). A piston slidable in a cylinder or a diaphragm may be employed in place of the bellows 14.

Title: Apparatus for Measuring the Moisture Content of a Gaseous Substance in a High Temperature Chamber
IPC: G01N25/62
Filed: 1968-05-21
Abstract: 1,190,154. Hygrometric apparatus. ICHIKIN KOGYOSHA K.K. May 21, 1968 [Nov. 1, 1967], No. 24275/68. Heading G1S. Apparatus for measuring the moisture content of a gas in a high temperature chamber comprises a casing 1, a wet bulb thermometer 11, a dry bulb thermometer 10 and a reservoir 4, continuously supplied with water through an opening 5. The flow of the water past a flow speed reducing plate 6 and through holes 7 in a plate 8 prevents the water from reaching its boiling point. An overflow pipe 9 determines the maximum depth of the water which wets a gauge 12 covering the thermometer 11 and the water temperature is measured on a thermometer 20. A partition 2 separates the reservoir 4 from a chamber 3 containing the thermometers 10, 11 and opposite sides 14 of this chamber are formed with rectangular apertures to allow the gas to pass through the chamber. The flow speed of the gas, which is measured by inserting an anemometer in an opening 17 normally closed by a cover 18, is controlled by sliding doors which vary the degree of opening of the apertures. Calibration curves of the moisture pressure against the temperature of the dry bulb thermometer for various temperatures of the wet bulb thermometer are used to determine the moisture pressure and hence the moisture content corresponding to the temperatures indicated on the thermometers 10, 11.

Title: Static Regenerative Direct Current Motor Control.
IPC: H02P7/298
Filed: 1966-10-03
Abstract: 1,167,025. Control of D.C. motors; converting. WEB PRESS ENG. Inc. 3 Oct., 1966 [21 Oct., 1965], No. 24459/69. Divided out of 1,167,024. Headings H2F and H2J. [Also in Division G3] The subject-matter of this Specification is identical with that described in Specification 1,167,024 but the claims are concerned with the firing circuit for the field rectifiers. Each of the networks 114, 115, comprises a unijunction transistor 118, 119, which provides firing pulses through transistors 120, 121, to output terminals 122, 123, connected respectively to pairs of controlled rectifiers. A differential amplifier 124 is associated with alternate energization circuits 125 for the networks 114, 115. If input signals of one polarity or the other are supplied to terminals 116, 117, either transistor 127 or 130 conducts to charge capacitor 131 or 132 which supplies an input signal to the respective unijunction transistor. Synchronization of the firing circuit with the field supply is effected, circuit 138 comprising transistor 142 supplying power across the base terminals of transistors 118, 119, and circuits 125. The period of each half-cycle of A.C. input during which such power is supplied is determined by the interval during which current is passed by the Zener diode 141 and transistor 142, the instant at which the firing signal is generated being determined by the magnitude of the input signal at terminal 116 or 117. During the period in which power is supplied to the bases of transistors 118, 119, capacitors 329, 332, are charged but the voltages thereacross are insufficient to fire the unijunction transistors until near the end of the cycle. This generates a firing pulse which is independent of that due to the input at terminals 116, 117, whereby the field current is rapidly reduced to zero by regenerating inductive energy back to the power lines.
