Title: Improvements in book-binding
IPC: B42C13/00
Filed: 1949-05-05
Abstract: 663,248. Bookbinding presses. KITCAT, L. G. Feb. 6, 1950 [May 5, 1949], No. 12032/49. Class 16. In applying pressure to books to remove the swell at the back of the assembled sheets the sheets are subjected first to uniform pressure over an area spaced from the back edge to grip the sheets against relative displacement in their planes and then to pressure over the swollen back edge. The book or books 1 are placed on a-platform 2 and a press head 3 urged towards an abutment bar 4 which is slidable in horizontal guides, against compression springs 5. The pressing in and removal of the swell 7 is effected by a pinching bar 8, which, prior to the displacement of the abutment 4, is spaced slightly away from the book receiving part of the machine as shown in Fig. 7. At the completion of the displacement of bar 4 the upper edge of face 8' of the pinching bar 8<SP>1</SP> comes into contact with bar 4. The pinching bar is then rotated about pivots 10 to bring its face 8' into co-planar relationship with the work-engaging face of the bar 4 and simultaneously the platform 2 is displaced downwardly away from the book by the engagement of part of the bar 8 therewith by means of cam 11<SP>1</SP>, bell-crank lever 14 and adjustable link 16. The press head 3 is moved by means of links 22, 23, arm 20 moved by cam 18 carried by shaft 12. The link 22 is pivoted to a bar 24, adjustable by screws 26 splined through pinions 27 driven by a chain 28 off a sprocket on the shaft of a hand wheel. The screws 26 engage a pair of coiled compression springs 32 to guard against breakage of the machine in the event of an increase in space between the bars 3 and 4 being demanded. The shaft 12 is driven by any suitable form of motor 40. Furthermore, the pivots 10 are given a vertical movement so that the bar 8<SP>1</SP> also has a smoothing action on the sheets. According to the Provisional Specification the sheets rest on parallel horizontal rods with the pinching bar notched along its lower edges to accommodate the rods.

Title: Airplane inflight refuelling apparatus
IPC: B64D39/00
Filed: 1954-04-27
Abstract: 740,334. Refuelling aircraft in flight. BOEING AIRPLANE CO. April 27, 1954 [May 18, 1953], No. 12175/54. Class 4. Mechanism for delivering fuel from a tanker aeroplane 1 in flight to a receiver aeroplane R includes a hose 5 extending between the two aeroplanes, upon the rearmost end of which is a primary drogue 8 for seating upon the probe P of the receiver aeroplane, and a secondary conical drogue 10 which in operation is fixed upon the hose 5 a short distance forward of the drogue 8 with its apex directed forwardly to maintain the hose between the aeroplane 1 and the drogue 10 taut at all times so that deflection of the hose resulting from relative movements between the two aeroplanes is confined to the length of hose 7 between the two drogues, whereby excessive whipping of the hose when slack is avoided. The size of the drogue 8 is such that it closes an aperture 3 in the aeroplane 1 when the hose is reeled in and the drogue 10 is of smaller size in order that it may pass through the aperture. The drogue 10 may be securely fixed to the hose 5 a distance from the drogue 10 less than the length of the compartment 2 in the aeroplane 1 in order that the drogue 8 may be drawn firmly over the aperture 3 or the drogue 10 may be mounted on the hose by releasable catches and held by spring fingers just inside the aperture 3 as the cable is reeled in so that the drogue 8 seats within it.

Filed: 1952-05-14
Abstract: 716,454. Typewriters &c. COXHEAD CORPORATION, R. C. May 14, 1952 [May 15, 1951], No. 12194/52. Class 100 (4) Type-wheel machines: type-wheel construction. -In a rear-strike machine using a type shuttle which can be indexed in either direction in response to the actuation of a key, the shuttle is provided with a line-forming symbol normally indexed at the printing position. Underscoring and ruling.-The line-forming symbol may be in the form of leaders 42, or single or double ruled lines 44, 45 as shown at 41. To print the required symbol on'y the operation of the case or figure shift keys is required together with the operation of a repeat strike button 65 which causes repeated printing and letter-spacing until automatica'ly stopped by a cam, adjustably mounted at the required position on the carriage. Depression of the button 65 effects the energization of a motor 67 having a rotary cam 70 closing a switch 71 to repeatedly operate a solenoid 47. A link 49, Fig. 6, moved by the solenoid causes an arm 62 to operate a three-unit letter-spacing pawl 61 and pivot a crank-lever 50 engaging a hammer escapement operating lever 46 in a manner described in Specification 676,221. When the carriage has reached a predetermined position the adjustable cam opens a switch 72 and the motor 67 stops. The depression of a button 64 causes single operations of the solenoid 47 to print one symbol at a time. Hammer impression arrangements.-The mechanism is simi'ar to that described in Specification 676,221 but a fork 56 attached to the crank-lever 50 and extending on each side of a hammer check rod 56 partly suppresses the impact of the hammer when printing the line symbols 42, 44, 45, by moving a thick zone 59 of the fork 54 into the path of the check rod 56 by the rocking of the crank-lever 50.

Filed: 1956-04-23
Abstract: 806,754. Turbines. GARRETT CORPORATION. April 23, 1956 [May 13, 1955], No. 12336/56. Class 110 (3). A turbine having a nozzle with a substantially uninterrupted surface diverging from the throat has means to interrupt the surface to divert a part of the nozzle jet stream so as to reduce the work performed by the jet stream on the turbine wheel. Gas is supplied to the convergent-divergent nozzle 17 of a turbine from a gas generator through a passage 15. The flow through the divergent portion 20 is controlled by mechanism 22 comprising a valve pin or rod 23 which slides in a sleeve 24 into and out of the stream of gas flowing through the throat 21. The rod 23 is relieved at 25 to provide a channel which conducts gas to an atmospheric exhaust passage 26. A solenoid 31 energized by a speed governor moves the rod 23 into the jet stream against the action of springs 28, 30. The arrangement of the springs is such that during initial movement of the solenoid, the light spring 28 only operates but on further movement of the rod 23 the heavier coil spring 30 is compressed. In the position shown the end of the rod 23 forms part of the surface of the nozzle. In a modification, Fig. 4 (not shown), a part of the wall of the nozzle is formed as a rotatable valve which may deflect flow from the outlet nozzle section to an exhaust passage. In another modification, Fig. 5 (not shown), a section of the nozzle outlet is rotatable.

Abstract: 196,189. British Thomson - Houston Co., Ltd., (General Electric Co.). May 3, 1922. Thermal current Meters; temperature errors, compensating for. - A U - shaped copper or other conductor 1 has a thermostatic element 14 mounted therein and co - operating with a non-return pointer 15 moving over the serrated edge of a scale 16. The U-shaped conductor is formed into a closed chamber by a block of fibre, hard rubber, or other insulating material 10 closing the back, a fibre or other insulating front plate 12, and a top cover-plate (not shown). The block 10 also serves to support the instrument. The U-shaped conductor 1 is connected to the terminals of the circuit, for example in place of the jumper or fuse connecting feeders in a manhole, by bolts passing through holes 4, 5 in ears 2, 3, which bolts may also secure the cover-plate. The conductor 1 is of such cross-section that the normal current flowing causes sufficient temperature rise within the chamber to obtain a readable deflection and to render changes of atmospheric temperature negligible. The bimetallic strip 14 may serve as a pointer, and the non-return pointer 15 may be replaced by a slider on the scale 16. The scale preferably reads from 0.7 to double the normal load current, and may be graduated in amperes or in percentages of normal current. The ears 2, 3 may be extended and have separate holes for the connecting-bolts and for attaching the cover-plate, or the cover-plate may be attached by a thumb-screw in the block 10. The cover-plate may have a slide above the scale 16, or may be dispensed with entirely. The ears 2, 3 may alternatively be formed as straight extensions of the U-member, or may be twieted in a plane at 90‹ or other angle.
