IPC: A43D85/00
Filed: 1917-01-26
Abstract: 103,673. United Shoe Machinery Co., (Assignees of Eppler, A.). Jan. 27, 1916, [Convention date]. Turn-shoes. machines for - A forepart - turning machine is provided with means to engage the toe portion of the upper externally so as to maintain the upper stretched over the form during the turning operation. The invention is described as applied to the machine described in Specification 9642/02. The upper-engaging member comprises a flexible arm 30 secured to a head 32, which is slidingly supported on the usual carrier 16 for the sole-engaging iron 15 and is connected with the carrier by a tension spring 33. The normal position of the head is determined by the engagement with its forward end of a shoulder 34 on the carrier, and as the iron 15 is advanced in the usual way, the member 30 moves forward with it and wipes the toe portion of the upper across an inclined face 40 on the supporting-form 5. The advance of the iron is limited by the engagement of a collar 35, formed on a rod 38 adjustably threaded into the head 32, with the face of a bushing 37 threaded in the end of a recess 36 formed in the usual arm 8. During the turning of the shoe proper, the member 30 remains in contact with the upper approximately at the tip line while the iron 15 is gradually withdrawn, and until the shoulder 34 contacts with the head 32, whereupon the iron 15 and the member 30 move backwards together.

Abstract: 142,785. Hartford - Fairmont Co., (Assignees of Peiler, K. E.). May 5, 1919, [Convention date]. Delivering molten metal; shearing.-Relates to the delivery from a tank furnace 1 of uniform charges of molten glass. The object of the invention is to deliver charges which are shaped to fit approximately the mould in which the charge is to be formed. According to the invention, the cross-sections at successive points along each charge are controlled by varying the rate of diacharge from the orifice 3. This variation is produced by the action of a vertically reciprocating plunger or impeller 13, driven by variable cam mechanism of the kind employed with the known paddle-feed or oscillating impeller. Figs. 27-31 show the action of the impeller 13, and Fig. 23 shows a tapered charge in a bottle blank mould. The diameter of the orifice 3 may be altered by exchanging the movable ring 52. The level of glass in the bag 2 is controlled by a gate 41. Shears 4 and delivery trough 5 of known kind are described. Reference has been directed by the Comptroller to Specification 157,159.

Abstract: 897,037. Determining relative quantities of fluid mixture constituents. UNITED KING- DOM ATOMIC ENERGY AUTHORITY. Jan. 5, 1961 [Jan. 16, 1960], No. 1655/60. Class 37. [Also in Group XVIII] A device for detaching mercury drops from capillary tube comprises a movable arm 1 for mounting the tube, stops 8, 9 limiting the movement of the arm and a solenoid 18 having an armature 16 which is coupled with lostmotion to the arm so that, when the solenoid is energized, the armature acquires considerable momentum before contacting the arm and moves it rapidly through a small distance, thus defining closely the instant of detachment of the drop. As applied to a differential polarograph, the aluminium-alloy arm 1 is bifurcated into two branches 3, 4 having clamps 5 for holding the capillary tubes and is pivoted about a vertical axis 2. The arm is held against the stop 8 by the net effect of two springs 29, 30 and carries a bracket 12 with a forked flange 13 engaging over a headed pin 14 adjustably fastened to the armature 16. A spring (not shown) presses a washer 25 on the armature against a forked bracket 26 to hold the armature in the outward position. Pulses of 0.02 second duration at 7 second intervals are supplied by the polarograph circuit and the rapid movement of the arm to the stop 9 shears the drops from the tubes.

Title: Improvements in or relating to the scrubbing of the interior surfaces of cooling zones
Inventor: KRAUS PHILIP BERKELEY
IPC: C01G23/07
Filed: 1957-01-16
Abstract: The interior surface of a cooling zone is scrubbed free from particles which may stick to the sides during cooling by passing therethrough, together with the material to be cooled, a particulate, inert, sublimable solid such as solid carbon dioxide, solid carbon hexachlorethane, ammonia carbamate or ammonium chloride.  The process is applicable to the production of metal oxides in the presence of a corrosive gas phase.  The cooling process is similar to that used in the preparation of titania described in Specification 776,419 except that the inert solids in this process are sublimable.  The titania is preferably manufactured according to Specification 707,560.  The cooler is made of a corrosion-resistant metal such as aluminium, nickel or stainless steel.  U.S.A.

Filed: 1943-02-03
Abstract: 563,308. Roll-film cameras. KODAK, Ltd., and NAGEL, H. Feb. 3, 1943, No. 1798. [Class 98 (i)] A film magazine for a camera comprises a cylindrical casing 8 carrying a guillotine cutter adjacent a film entrance slot, one member 28 of the cutter serving to close the slot and having a radial projection 35 which engages in a fixed guideway in the magazine-receiving chamber D of the camera when the magazine is inserted in an axial direction. When the magazine is subsequently locked in the chamber by a partial rotation, which causes locking means, such as tongues 39, carried by it to engage corresponding means, such as pins, in the chamber D, the projection 35 holds the closure and guillotine member 28 from rotating with the magazine, so that the film slot is uncovered. Conversely, rotation in the opposite direction to unlock the magazine causes the member 28 to close the film slot and, in co-operation with a fixed blade 33, to sever the film. The blade 33 is formed by one edge of a slot formed in a cover-plate 29 beneath which the member 28 is slidably mounted. A film core 16 is rotatably supported by the end walls of the magazine and is driven by a camera spindle 15 which passes through an aperture in the removable end wall 9 and engages within the core. The magazine is provided with the means described in Specification 563,307 for guiding and automatically connecting the leading end of the film to the core. Specifications 549,194 and 563,304 also are referred to.

If the echo signal is lost or too weak, the previously read-in signal is repeatedly read out and prevents flicker on a CRT display (not shown). Continued loss of echo signal activates coil 7 on the changeover device to result in a blank display. Shifting of the depth range inspected also triggers coil 7 to provide an uninterrupted display of the previous echo sounding.
