Title: A Modular Unit for Making Electrical Interconnections
IPC: H01R13/20
Filed: 1968-07-02
Abstract: 1,176,273. Two-part couplings. AMP Inc. 2 July, 1968 [26 July, 1967], No. 31508/68. Heading H2E. In a modular unit comprising a plurality of modules 6 of insulating material, (Fig. 2) provision is made for mounting each module on a carrier 4 in one of three different relative orientations, such that adjacent modules in the first orientation are electrically connected, as are all those in the second, whereas those in the third orientation are electrically isolated, some or all of the connectors in the module sockets are commoned. A bus-bar panel 118 (Fig. 3) is supported in the base 104 of the carrier 4 and has a copper bus-bar 122 exending along its length, midway between the sides, and further bus-bars 124a, 124b, 124c, 124d and 124e extending obliquely towards the central bar 122, there being a regular array of apertures on either side of the central bar 122, into which are inserted resilient contact pins 126 and 128, positioned in the base of the modules. Marking devices, 98 and 100 are present in the top of the modules (Fig. 2) and the three relative orientations are defined with respect to the fixed marker boss 146. When the module is in these different orientations, the pins 126 and 128 enter different apertures, so making contact with different busbars (Fig. 3) and hence with different sets of other modules. Each module (Fig. 4) comprises a housing 18 in the base of which are blocks 30 and 32, between and about which fits a conductor commoning element 40. This is made from, for example, half-hard tempered bronze, by die stamping and forming operations, and has integral contact ears 54, offset from the base by neck sections 53. Suitable cutting may produce unconnected sets comprising either three or six contact bars. A connector-retaining member 60 fits over the ears 54 and rests on the blocks 30 and 32, and is preferably of a moulded plastics material, e.g. nylon, but may be of metal. Over and into this fits an insert 74 of resilient material. e.g. silicone or neoprene rubber in the underside of which is a plurality of projections having grooves in their ends to locate the frame of the retaining element 60. The insert 74 has passageways 78, with constricted neckportions 80 to grip a supply wire 16 and form a seal. The wire carries a contact pin 8, which is held in position by the abutment of its enlargement 12 against a shoulder 70 in the retaining member 60 (Fig. 7, not shown). The contacts 126 and 128 extend downwards through the base 18 of the housing. Over the insert 74 is clipped a cover-plate 90, which may be of nylon or similar material. The carrier 4 is held together by a hooked clip 110, and also by means of mounting screws. It may be joined to other carriers by means of the interfitting parts 111, 114 and 116.

Title: Improvements in or relating to indicating instruments particularly for aircraft
IPC: B64C25/28
Filed: 1935-11-15
Abstract: 465,882. Electric selective signalling systems. BENDIX AVIATION CORPORATION. Nov. 15, 1935, No. 31675. Convention date, July 22. [Class 40 (i)] [Also in Group XIX] A single indicator gives quantitative indications of a selectable one of a number of functions by movement of a switch to the required position, pilot lamps being provided which indicate when any one of the functions varies by more than a predetermined amount. The indicator has a number of concentric scales for the various functions and may be fitted with two pointers which give simultaneous indications of the same function of two sources. The invention is described as applied to supervisory signalling of the oil pressure, fuel pressure, oil temperature and water temperature of two aeroplane engines. As shown in Fig. 1 the local instruments for measuring the functions of the two engines 4, 5 are connected by poly-phase, single-phase transmission systems to a central instrument (Fig. 1<a>) whilst cut-outs 18, 19 .... 24, 25, which may be of the type shown in Fig. 4, are connected to pilot lamps A, B, C, D. When any one function of one engine varies by more than a predetermined amount the contact arm 56 (Fig. 4) makes contact with either 54 or 55 and the corresponding pilot lamp A, B, C, D (Fig. 1<a>) lights. The pilot turns the switch so that the pointer 15 is towards the lighted pilot lamp and then pointers 2, 3 are set by polyphase, single phase signalling systems to indicate quantitatively the values of the function for both engines. The notches 16, 17 on the pointers indicate with which engine the pointer is associated.

Title: Sealing apparatus for the rotating hopper of a blast furnace
IPC: C21B7/18
Filed: 1961-09-07
Abstract: 922,048. Charging shaft furnaces. JOHN MOHR & SONS. Sept. 7, 1961 [Nov. 17, 1960], No. 32156/61. Class 51 (2). Apparatus for charging shaft furnaces of the double bell, double hopper type in which the upper hopper rotates, has a gas seal comprising a sealing baffle 73 disposed around and below the rotary hopper 11 and closed by a bell 63, the arrangement being such that the bell 38 closing the rotary hopper is fixed vertically in relation to the lifting device 50 by its operating sleeve 40, and the bell 63 is movable vertically in relation to the said lifting device by its operating sleeve 61, a compression spring 59 being located between the tops of the two sleeves to allow relative motion therebetween. The buffer 11 is driven by a motor 16 through a spur gear 15 and a ring gear 13, and is supported by lower and upper rollers 20 and 24 respectively and side rollers 29. The bell 38 and its sleeve 40 which rests by a bearing 48 on a support 49 forming part of the lifting device also rotate with the hopper 11 and an arm 52 engaging a slot 53 in the outer framework 54 prevents this rotation being transmitted to the lifting device. In the closed position shown the spring 59 is under compression so that, as the lifting device 50 moves downwardly, the bell 38 leaves its seating and when the spring 59 reaches the limit of its expansion the bell 63 also moves off its seating. In a modification, Fig. 2 (not shown), the spring is disposed within the upper part of the bell 38 which engages an annular recess in its operating sleeve 40, allowing vertical movement therein, the spring bearing against a flange on the sleeve 61. U.S.A. Specification 1,891,821 is referred to.
Patent GB-428786-A (GB)
Title: Improvements in or relating to alternating current electric circuit breakers
IPC: H01H9/56
Filed: 1933-11-18
Abstract: 428,786. Arc-rupturing in switches. MARSTON, G. S., and STATTER & CO., Ltd., J. G., 16, Great George Street, London. Nov. 18, 1933, No. 32202. [Class 38 (v)] A circuit-breaker having an auxiliary contact carried on the main movable contact carrying member and an auxiliary contact carried on the fixed main contact support, one auxiliary contact being slidably carried, has electromagnetic means energized from the line for maintaining the auxiliary contacts closed against the action of resilient loading means after the main contacts have opened, until the instantaneous current has failen to such a value that the loading means overcomes the electromagnetic means to open the circuit finally at the auxiliary contacts. Fig. 2 shows diagrammatically a breaker in the act of opening ; one half 12 of a magnetic ring is fixed to an extension of the carrier of the main movable contact 1, whereas the other 13 is controlled by springs 14 and connected by a spring as 10, Fig. 4, so as to move with a contact 8, which is slidably mounted in guides 7 fixed on the main fixed contact 2. The auxiliary movable contact comprises two parts 9 pivoted to a block 6 on the extension and urged apart by a spring 11. When opening on short-circuit or overload, 1, 3 separate and then 4, 5 but owing to the field set up in the ring 12, 13 by the current, 8 slides in the guides 7 and remains in contact with 9. At zero of the cycle the field is insufficient to overcome the force of springs 14, so 8 is separated from 9 and the circuit is finally opened. On normal loads, the field is inadequate, and 8, 9 separate at about the same time as 1, 3 so that the circuit is finally opened at 4, 5, which contacts are also the first to close. In the closed position, the shunt path is short-circuited by 1, 3 so the ring is unable to exert any choking effect, but such effect comes into play when 1, 3 open. The carrier of 1 may be the bridging member of an oil-switch with the parts so shaped as to circulate cooling oil during the opening movement. Instead of the ring being magnetized by a straight extension, a solenoid winding may be formed by looping the extension round the half-ring a desired number of times. In order to prevent sparking at the main contacts due to the choking effect of the ring, a resistance discharge path may be provided, such as shunt contacts adapted to separate before 4, 5 separates. The Provisional Specification refers also to a solenoid and spring-controlled plunger, and to a time-delay action in tripping.

Filed: 1926-12-23
Abstract: 263,812. Excetsior Feuerl÷schgerõte Akt.-Ges., and Treichel, O. Dec. 24, 1925, [Convention date]. Fire-extinguishing by foam; chemicals. - In the production of foam by the addition of a foam developer to a water-gas mixture, the foam developer is first brought into a very finely divided condition. This is effected by suspending the developer, for example saponin, in quantities above normal solubility, in a colloidal solution, such as a solution of albumen, with vigorous stirring. The mixture may now be added to the water-gas mixture, or it may be dried and the product used in the dry state. The same result may be achieved by mixing dry saponin with a powder insoluble in water, such as Kaolin or China clay.

Title: Improvements relating to weft-replenishing mechanism for the shuttles of looms for weaving
IPC: D03D45/20
Filed: 1921-12-06
Abstract: 198,708. Horrockses, Crewdson, & Co., Ltd., Lewtas, J., and Blackhurst, E. H. Dec. 6, 1921. Weft-feeler arrangements; shuttles, changing weft carriers in, automatically.-The weft feeler c, Fig. 1, controlled by a spring c' is pivoted to a bell crank d. A rod &c. e pivoted at d<2> to the lever d engages the weft fork hammer, so as to be moved thereby about the pivot d<2>, and when the weft is substantially exhausted projects into the path of a lever &c. h on a shaft i, whereby the shaft is turned and a member thereon actuates the replenishing mechanism to transfer a fresh cop into the shuttle. The lever &c. h is made of a comparatively large area so as to prevent actuation thereof at the wrong time, the rod &c. e engaging the face of the lever &c. under such circumstances instead of projecting into the path of the lever &c. If the shuttle does not enter the shuttle box, the nose or a part of the shuttle engages and operates a sliding spring- controlled member having a wedge-shaped or inclined part, which rocks a depending lever engaging an inclined projection on the shaft i. This shaft is consequently rocked and the lever h is moved to such a position that the rod &c. e cannot move behind it, and consequently the replenishing mechanism cannot be operated. When the loom starting-lever u, Fig. 6, is moved into position for stopping the loom it moves a spring- controlled lever t into engagement with a member r, Figs. 1 and 6, projecting from the member e, thereby preventing this member from being operated to cause replenishment. According to the Provisional Specification, the rod may pass through an extension of the weft hammer, and the engaging edges of the rod and shaft projections may be in knife-edge form.
