Title: Improvements in or relating to Cross-bar Selector Switches
Inventor: LOSTY HOWARD HAROLD WALTER
IPC: H01H67/26
Filed: 1966-05-12
Abstract: 1,196,111. Electric selectors. GENERAL ELECTRIC & ENGLISH ELECTRIC COMPANIES Ltd. 8 Aug., 1967 [12 May, 1966], No. 21067/66. Heading H1L. In a cross-bar switch whose contact sets are capable of being mechanically latched, the select and actuate bars are driven through the intermediary of electrostatic clutches which employ the Johnson Rahbeck effect. The clutches may be of the type described in Specification 994,676. First embodiment (Fig. 1). Spring-loaded select (horizontal) bars 1 and actuating bars 3 are attached to stainless steel bands 9 which are wrapped round rotatable, semi-conductive partially-pyrolysed, cellulose carbon drums 8. The latter are rotated sequentially by means of separate or a common motor(s) (not shown) while the two required bands are pulsed with 250 volt D.C. Consequently a select bar 1 (Fig. 2) is moved to the right, thus moving all the rigid selecting fingers 5 pertaining to this bar into positions where one of them will be moved vertically upward by a lug 18 on the relevant actuate bar when the latter is moved under the influence of a D.C. pulse on its band 9. The thus selected finger is thereby trapped at the top of the right-hand limb of a U-shaped slot 19 in a static bar 17 which extends in parallel with the select bar, when the select bar moves back to the left and the actuate bar drops down (both bars being spring-loaded). The finger 5 (Fig. 4) is attached to a comb 15 which, in response to movement of the finger, moves its bare wire contact set 12 into engagement with the corresponding horizontal contact multiple consisting of strips 13. The bare wire contacts are multipled by means of vertical strips extending through the insulating blocks 14. An operated contact set is released by operating its select bar whereby finger 5 drops down the left-hand side of an inverted L-shaped aperture 20 in the select bar and is then moved back to the lower left corner of aperture 19 when bar 1 is restored. Second embodiment, Fig. 5. The select 1 and actuate 3 bars are controlled as in the previous embodiment but in this case, motion of a select bar (to the left) causes a row of rods such as 26 to rotate clockwise whereafter one of them is further rotated by the upward movement of an actuate bar. When bar 1 returns to the right, rod 26 is trapped by engagement of its arm 27 with the tapered, upstanding lug 31 on bar 1. Bar 3 then drops back without affecting rod 26. The cross-point sets consist of interleaved planes of horizontal and vertical bare wires 23, selected ones of which are connected together through the intermediary of metal clips 30 carried on the rods 26. Release of a cross-point is effected by re-enabling the corresponding select bar.

Title: Arrangement for separating mixtures by centrifuging
IPC: B04B5/12
Filed: 1937-07-30
Abstract: 491,112. Centrifugal separators. MAIER, R. July 30, 1937, No. 21182. Convention date, July 30, 1936. [Class 23] Suspended particles are separated from gases by means of a rapidly rotating smooth pipe, closed at the end, immersed in the gaseous mixture ; the pipe causes the surrounding gas to rotate with it and the lightest zone immediately adjacent the pipe wall is continuously withdrawn either axially, or through perforations in the pipe wall, while the heavier parts remain in the mixture or accumulate at the wall of its container. In the form shown in Fig. 2 the end of the pipe is expanded to form a hollow cylinder 1a with a large number of peripheral passages 2a. The pipe, which is rotated by an electric motor 4b, passes through a chamber 3a and is supported in stuffing boxes 3b, 3c. A duct 5a connects a suction pump 5b to the chamber 3a. The cylinder 1a is rotated in the mixture and the light component is drawn by the pump 5b into the pipe through one set of peripheral perforations, then into the chamber 3a and duct 5a through another set. The degree of separation of the dust or gas components can be regulated by varying the speed of rotation of the cylinder 1a or the suction of the pump. In the form shown in Fig. 3, the container 1 is partly cylindrical and partly conical, and the rotating pipe consists of sieve cylinder 4 rotated by the motor 6. Impeller blades 8 at the top of the cylinder draw the separated light component through the sieve and discharge it through the pipe 9. In a modification the container drum 1, Fig. 5, has an inlet 2 and encloses a three stage separator. The first two stages have drums with sieve walls 7, 7<1> and the third stage has a drum with a thick wall 7<11> with tubular passages. Impeller blades 8, pass the light component from the first separation to the second stage, and blades 8<1> pass it from the second to the third stage. The heavier components may be drawn off by the outlets 3, 3<1>. In a further modification the material supplied is passed through disintegrating apparatus before it reaches the separator, and the light component is drawn off axially from the gap between the rotating cylinder and a plate arranged outside it at right-angles to its axis.

Abstract: 626,114. Protective cut-out arrangements; thermal switches. METALS & CONTROLS CORPORATION. Aug. 5, 1947, No. 21232. Convention date, Sept. 15, 1939 [Class 38(v)] A protective arrangement for an energy translating device such as a poly-phase motor utilizes two thermally-actuated, doublepole switches, each having a single snapaction bowed bimetallic disc 4 electrically welded to a supporting plate 2. The disc 4 has a contact button 10 which co-operates with a second fixed plate 11 to form one " pole " of the switch, and a screw 6 rotatably engages the centre of the disc to permit the adjustment of the operating temperature. The other " pole " of the switch is formed by a resilient blade 14 carrying a contact 16 which co-operates with a fixed contact 17. This blade is fixed at 15 and is actuated by the disc 4 by means of an insulating push rod 13. The disc is heated by a heating coil 20, by the current flowing through the disc and if the switch is fixed on or in the motor, by the heat of motor. Fig 1 shows the use of two switches to protect the delta connected windings 29 of a three-phase motor, the connections being such, that the opening of either switch under overload conditions interrupts the current in all three phases. In this example the disc 4, the element 20 and the contacts 10, 11 of each switch are connected in series with a supply line and the contacts 16, 17 of both switches are connected in the third supply line. This arrangement may also be applied to apparatus having windings connected in star or two-phase three-wire apparatus, Figs. 6 and 7 (not shown). In a further embodiment, Fig. 5 (not shown) the two switches are used to protect a two-phase four-wire apparatus, each winding being connected in series with the contacts 10, 11 of one switch and the contacts 16, 17 of the other switch.

Filed: 1936-08-06
Abstract: 479,461. Aircraft with rotary wing systems. KAY, D. Aug. 6,1936, No. 21712. [Class 4] In a rotating blade arrangement for aircraft with a normally autorotative rotor, each of the blades is provided with sliding (or guiding) means adapted to engage with guiding (or sliding) means provided on the rotor hub, said means being so disposed as to provide fulcra permitting the displacement of the blade in the general plane of rotation, such displacement being accompanied by a change from a normal or positive pitch angle to a neutral or negative angle both when the blade experiences a lagging displacement during starting of the rotor and a leading displacement when the rotor is being braked, the said means at all times permitting flapping. The root end of each blade spar 1, Figs. 1 and 2, is formed or provided with a cross member 2 formed with or carrying ball ends 3, 4 engaging in spaced oppositely inclined slots 5, 6 in rotor hub 7, providing curved tracks along which the balls can travel. In the normal radial position the centrifugal force is taken by the ends of slots 5, 6. Flapping takes place about an axis passing through the centres of balls 3, 4. A leading swing causes the blade root to pivot about ball 2, ball 4 moving downwardly in track 6 to effect a reduction in pitch angle, whilst lagging causes the blade root to pivot about ball 4, ball 3 now moving upwardly in track 5 again producing reduction of pitch angle. In a modification, the tracks may be formed in members secured to the blade roots which co-operate with spherical or like members fixed in the hub. Means may be provided for altering the mean pitch angle on the ground or in flight by providing for angular adjustment of the ball-carrying or the slotted element.
