Filed: 1958-10-24
Abstract: 866,993. Valves. KOVO-FINIS, NARODNI PODNIK. Oct. 24, 1958, No. 34196/58. Class 135. A gas control device for a metal spraying piston comprises at least two cocks or valves, controlled by a single actuating element and interconnected in such a way that the movement of the cock or valve for controlling air to the burner is delayed both on opening and on closing with respect to the opening and closing movement of the valve or cock for controlling oxygen. In an embodiment a housing 3 contains two mutually coupled plugs 1 and 2 having passages e, g, h and i for the passage of acetylene, burner air, motor air and oxygen respectively. The two plugs are coupled together by means of a projecting member k on the plug 1 engaging in a slot in the projection 11 of the plug 2, the slot being widened in a radial direction to permit relative movement between the plugs (see Fig. 2). Plug 1 is actuated by a lever 8. On moving the plug 1 from the closed towards the open position the plug first moves through an angle before the second plug commences to move. In this way the opening or closing of the air passage g is retarded in relation to the opening or closing of the oxygen passage i. The passages e and i are provided with ignition slots f and j, the latter being shorter than the former so that acetylene is supplied in advance of oxygen.

Abstract: 387,082. Glass manufacture. GREGG & CO. (KNOTTINGLEY), Ltd., Hope Glass Works, Goole Road, and GREGG, H., Brooklyn House, Cow Lane, both in Knottingley, Yorkshire. Dec. 11, 1931, No. 34331. [Class 56.] Relates to a feeder of the kind in which the reciprocating plunger is surrounded by a tubular member or " sleeve " for controlling the flow of glass to the outlet. According to the invention, means are provided for preventing the iron parts that support the sleeve from being damaged by exposure to gas flames and hot gases, and thus to prevent iron scales from falling into the glass. The sleeve 1, Fig. 1, is made of refractory material and is carried by a metal plate 3 which is secured to the lower ends of two racks 22. An iron ring 7 fits into groove 6 in the sleeve and is secured to the plate 3 by bolts. These bolts engage slots in the edge of the plate 3 and thus permit easy removal of the ring 7 and the sleeve. Below the groove 6, the sleeve is enlarged to form a flange 4, the underside of which is bevelled, as shown. The bevelled portion 5 acts as a deflector which causes the hot gases arising from the forehearth 12 to travel outwards away from the sleeve holder and the parts connected with it. The ends 41 of the plate 3 are slotted to facilitate detachment from the racks 22. The ring 7 may be dispensed with, the sleeve being gripped by a flange on a ring which is formed on the underside of the plate 3. When the sleeve is to be rotated, the holder 3, Fig. 7, is provided with flanges 43 which slide into parallel guides 44 formed on a tubular member 45 that rests on a ball bearing on a plate 48 secured to the racks 22.

Title: Improvements in or relating to card feeding mechanism for statistical machines
IPC: G06K13/077
Filed: 1931-12-11
Abstract: 389,924. Statistical-apparatus. THOMAS, A., 11, Sandy Lane South, Wallington, Surrey. Dec. 11, 1931, No. 34406. [Class 106 (i).] In a machine for feeding cards to tabulating, sorting, and like machines, e.g. to a tabulating machine, as described in Specification 26896/13, [Class 106 (i), Calculating &c.], the cards are registered laterally by giving a lateral movement to the feed rollers which advance the cards longitudinally and form the sole support of the card, and a fixed side stop determines the lateral position of the card. As shown in Fig. 1 (Prov.), the feed rolls comprise fixed lower feed rollers 1 and spring-pressed upper feed rollers 3, and the upper rollers 3 are moved to the left to register the edges of the cards against a fixed stop 17. The rollers 3 are moved by means of oscillating U-shaped members 9 which move up and down with pillars 11 attached to the pin box of the tabulator. Fixed cam slots 13 engage pins on the members 9 to oscillate them, and the members 9 engage grooved discs 8 fixed to the shafts of the upper discs 3 and so move these discs laterally. The discs 8 also move the positively driven lower rollers 1 correspondingly, and when the card abuts the stop 17 the rollers 3 can yield owing to their spring mounting. The extent of movement of the rollers 3, 1 is constant and is such that cards entering at different lateral distances from the stop 17 can be registered thereby. In a modification, Fig. 2 (Comp.), which is applicable to key-operated card-punching machines, the rollers 1, 3 are not yieldingly mounted, but they are reciprocated laterally by a cam 108 and lever 106 with a striker 104 engaging a grooved disc 103 on the shaft of the lower roller. The rollers 1, 3 are moved away from the stop 5 by the cam 108 and return by spring action so that when the card abuts the stop 5 their motion ceases.

Title: Apparatus for detecting preselected classes of metal objects
IPC: G01V3/10
Filed: 1971-07-26
Abstract: 1350273 Electromagnetic testing WESTING- HOUSE ELECTRIC CORP 26 July 1971 [8 Oct 1970] 34854/71 Heading GIN The invention relates to detecting a relatively large ferromagnetic mass e.g. handguns and distinguishing it from thin metal objects such as keys, parts of radio sets, cameras, etc. For this purpose the detector is energized at two different frequencies (high and low) and the signals from the search coils are resolved into inphase and quadrature components. It is shown Fig.3 that the ratio of the inphase components (i.e. power loss) for thin metal curve A and a gun curve B differs considerably. The phasesense of the quadrature component discriminates between magnetic and non-magnetic material. A block schematic circuit for this purpose is illustrated in Fig. and is substantially selfexplanatory. When the quadrature component indicates "magnetic" and the ratio of the inphase signals indicates "large" comparators feeding an AND circuit trigger an alarm. Provision is also made to indicate an excessive. amount of non ferromagnetic material. A mutual inductance 22 may be used to null the output of the seach coil C2 in the absence of metal. Figs. 5A, B (not shown) illustrate arrangements of coils around a "search room" along three orthogonal axes to ensure detection of the major axis of a gun. Distinct sets of pairs of high and low frequencies may be necessary to avoid interaction between the axes.
