Title: Method and apparatus for providing an annular channel in a tubular member
Inventor: RIMAN PERCY HERBERT
IPC: B21D15/10
Filed: 1958-05-09
Abstract: 861,507. Making corrugated pipes; stamping. ARMSTRONG SIDDELEY MOTORS Ltd. May 4, 1959 [May 9, 1958], No. 14854/58. Classes 83 (2) and 83 (4). A method of forming in a ductile tubular member a coaxial annular channel of which at least a portion is of greater width than the channel mouth includes the steps of lightly and annularly gripping the inner and outer peripheries of the wall of the tubular member at each lateral side of an initial, coaxial channel formed therein of filling the channel with a liquid, and of applying pressure to the liquid for distorting the channel wall outwardly into conformity with concavities of tools, which can afterwards be moved to release the tubular member to produce a channel of the desired final form. In an embodiment a tube 11 initially formed with a radially outwardly-extending parallel-sided annular channel 12 is placed on an inner annular support formed from two abutting ring-like parts 13, 13a which form an annular recess 14 in their outer faces. The outer support is formed from two axially movable aligned annular portions 15, 15a assembled on the tube on each side of the channel 12 each portion having concavities 16, 16a. The channel and recess contain an endless rubber tube 17 filled with a liquid e.g. water or oil. In operation, with the support portions 15, 15a lightly engaging the sides of the channel 12, hydraulic pressure is applied to extend the tube into engagement with the channel wall and partially to distort it into the concavities 16, 16a. The support portions 15, 15a are then advanced towards each other to draw the flanking parts 12a of the tube inwardly against the light grip of the supports. The hydraulic pressure is increased and the support portions further advanced. This step is repeated until the channel is fully formed as shown in Fig. 2. Similarly, a radially inwardly extending channel may be formed in the tube 11. Local bulges may be formed in the channel by providing recesses 19 in the concavities 16, 16a of the support portions 15, 15a.

Abstract: 1,046,671. Moulding hollow articles; laminating. CHARLES CLAY & SONS Ltd. April 10, 1964, No. 14991/64. Headings B5A and B5N. [Also in Division G2] A multi-layered, hollow, article is formed by heat softening a sheet of thermoplastic material, placing the sheet, with at least one other sheet of thermoplastic material, over a former mounted on an electrically conductive backing member, pressing the sheets over the former by means of a hollow electrically conductive forming tool having a cross-section corresponding to that of the base of the former, so that the sheets are peripherally held between the backing member and the tool, and finally applying a H.F. oscillation between the backing member and the former to bond the sheets together. In the particular embodiment a spectacles case is formed over a former 15, 16 from a heat softened sheet 10, sandwiched between a decorative sheet 19 and a " suede plastic " sheet 18, by means of a forming tool 20, 23, as shown in Fig. 7. The outer wall 23 of the tool is provided with a knife edge so that the sheet is cut simultaneously with the bonding. Prior to the forming operation a strip 14 of woven nylon is placed between members 15 and 16 and welded to the sheets, to form a hinge in the finished case, the forming members 25, 26 being of such a length as not to sever the sheets. A lug 30, formed on the periphery of the case during the above operation is then heated and bent to form a catch to retain the case in its closed position. The heated lug is placed over a projection 45 of platform 31 and bent therearound by a member 37, pivoted to the upper end of spring biased member 39, itself pivoted to base 40. Member 37 is actuated by a piston 38 and at first pivots about the upper end of member 39 until it hits stop 43, whence it moves forward in the direction indicated by arrow 44 thus bending the lug around projection 45 as in Fig. 9. Upon withdrawal of the member 37 the lug springs back to the position in Fig. 10 (not shown) to form the finished catch. The forming may be assisted by resilient material e.g. formed plastics as in Fig. 7. The bonding may be performed by a heat-sensitive adhesive placed between the sheets or may be effected by a direct welding of the sheets.

Abstract: 673,852. Automatic gramophones. MORTIMER, E. W., and GARRARD ENGINEERING & MANUFACTURING CO., Ltd. May 19, 1950. [June 3, 1949] No. 14998/49. Class 40 (ii). In a record changer, or a gramophone with an automatic trip mechanism, in which a taptap lever frictionally coupled to the pick-up arm is tripped at the end of the record, the said tap-tap lever is uncoupled from the pick-up arm before the release of the trip mechanism. The taptap lever 1, Figs. 1 and 2, has a double bent end 10 and is mounted for pivotal movement about a pin 14 in such a manner that, by means of a slot 12, limited up and down movement is permitted whereby the tap-tap lever 1 may be uncoupled from frictional engagement with an arm 17 of a bellcrank which is also pivoted about the pin 14 and is coupled to the pick-up arm by another bellcrank 22, 24. The striking cam .4 on the turntable spindle has a sloping side surface 5 which moves the tap-tap lever against the frictional engagement with the arm 17 during normal feed in of the stylus when a record is being played, but the striking cam 4 also has a sloping upper surface 6 which lifts the tap-tap lever out of contact with the arm 17 during the accelerated movement at the end of the record. In a record changer, the tap-tap lever tilts a member 29 about an axis 30 so that a downwardly projecting arm 31, Fig. 4, rocks a lever 32 about a point 33, Fig. 1, and trips a detent 34 which releases a bell-crank 37 which, under the influence of a spring 39 strikes a pin 40 on a cycling cam-disc 41 to start an automatic cycle. In a gramophone with an automatic brake a tap-tap lever 44, Figs. 7 and 9, lifts the end 46 of a bent rod 47 to trip a detent 53 which releases a brake arm 56 having a turntable brake-pad 61 and switch contact 59 whereby the motor and turntable are stopped.

Abstract: 353,137. Angle -measuring instruments. NAAMLOOZE VENNOOTSCHAP NEDERLANDSCHE TECHNISCHE HANDEL MAATSCHAPPIJ GIRO, 9, Oranje Straat, The Hague.-(Assignees of Anschutz & Co. ; Neumuhlen, near Kiel, Germany.) May 16, 1930, No. 15060. Convention date, May 24, 1929. [Class 97 (ii).] A sighting device for measuring the variations in direction of distant objects from a ship is stabilized in azimuth by a gyroscopic compass repeater and is given a superposed adjusting movement by a slow-motion hand-wheel, the superposed motion being electrically transmitted to an angle indicator, the pointer of which may be disengaged from the drive as desired and read while at rest. In one form, Fig. 1, a telescope 1, preferably binocular, is secured by a set-screw 13 to a spindle 2 which is rotatably mounted in a gimbal-suspended casing. The spindle 2 is driven by the motor 10 which is connected to a master gyroscopic compass so that the direction of the telescope is not affected by turning of the ship. In order to superpose adjusting movements of the telescope on the movements caused by the motor 10, the latter is mounted on a disc 9, driven through gearing 8, 7, 5, 4 by a slow-motion hand-wheel 3. A distant angleindicator operated by the transmitter 6 indicates the displacements in azimuth of the telescope. The motor 14 of the indicator drives a pointer carrier 15. The pointer 19 is normally held out of engagement with the carrier 15 and presses against the bottom of a sleeve 21, by rotation of which the pointer may be brought to the zero position. A plunger 23 may be depressed against the spring 20 to cause the pointer 19 to engage the carrier 15.

Abstract: 1427100 Television recording and playback GRUNDIG EMV 4 April 1974 [4 April 1973] 15069/74 Heading G5R [Also in Division H4] To reproduce and display a still picture corresponding to the video signal recorded in an oblique track on a magnetic tape (one frame is recorded in each oblique track), the tape advance motor is switched off when a minimum in a signal representative of the envelope of the reproduced video signal from the track coincides with a signal denoting that a transducer head of the playback head wheel is positioned at an end of the track. This ensures that a track such as 4 (shown in chain lines) is scanned when the tape is stationary instead of a track such as 3, track 4 being such that those sweep areas which lie between the oblique tracks 2 recorded with the tape moving fall chiefly at the edges of the picture i.e. in the vertical blanking intervals. In Fig. 3 the reproduced FM video signal received at 5 is rectified 7 to develop a signal representative of its envelop which is gated via an FET switch 8, controlled by head wheel position-indicating pulses applied via a phase correcting circuit 9, on to a capacitor 10. For still picture reproduction a start pulse is applied to terminal 15 to set bi-stable 16 so that a voltage for slow tape advance is applied to the tape advance motor. The resulting voltage on capacitor 10 is integrated 11, differentiated 12, 13 and applied to a pulse shaper 14 which is responsive to positivegoing transitions to deliver a pulse which resets the bi-stable 16 to switch off the tape advance motor and actuate the motor brake.
Patent GB-151023-A (GB)
Abstract: 151,023. Western Electric Co., and Polinkowsky, L. May 1, 1918. Addition to 151,167. Drawings to Specification. Automatic exchange systems; metering-systems.-Relates to systems of the kind described in the parent Specification in which calls are extended over connecting-circuits controlled by sequence switches having two talking positions, special calls (such as those to toll operators) holding the switch in the first talking position, in which case metering is prevented, while ordinary calls advance the switch into the second talking position, metering taking place in the usual manner on the release of the connexion. According to the present invention, the means which prevent metering when a call is made to a special position, such as a toll operator, may be disabled by the depression of a metering-key by the operator, whereby in this case also the call is metered during the release of the connexion. The invention is described as applied to the system of the parent Specification, the only changes effected being the provision of a metering-key in the tolloperator's cord-circuit, and the addition of two relays and their associated circuits to the circuits of the call-finder and group-selector. The depression of the' metering-key opens the circuit over one side of the trunk and connects a metering-battery to the other side of the trunk, thereby energizing one of the additional relays at the first selector. This relay locks up over a holding-winding and the second relay, which (1) opens the circuit of the metering-preventing relay so as to ensure the metering of the call in the same way as the metering of an ordinary call during the release of the connexion, and (2) prepares a circuit to move the sequence switch out of its eleventh position when the operator withdraws the plug at the end of the conversation.

Filed: 1936-05-29
Abstract: <PICT:0461108/IV/1> Highly-twisted crape threads of or containing filaments of a cellulose ester or ether are produced by passing the thread through an atmosphere made by mixing steam with cool air or other cool inert gas and inserting at least the last part of the crape twist while the thread is under the influence of the steam and gas atmosphere.  The steam and gas are preferably separately introduced into a chamber so that they mix near the path of the thread and may be under slight pressure or the pressure inside the steam chamber may be slightly below that of the atmosphere and air allowed to enter therein through suitably-disposed apertures.  As shown, the thread 3 is twisted as it is drawn off the package 2 carried by a spindle 1 provided with a flyer 4 and passes through an eye 8 in the steam pipe 7 to an extension piece 9 also provided with an eye 11 through which the thread passes to the winding package 6. Steam is supplied to the pipe 7 from a header 12 connected to the pipe by branches leading to nozzles or orifices 14 in the pipe and cool air is led from a header 15 to the pipe 7 by branches 16; the air inlets are preferably more remote from the thread than the steam inlets.  In another arrangement, the extension pieces are connected to a second pipe provided with exit eyes for the threads and connected by branches with a suction pipe, holes being provided in the extension pieces for the admission of air and, if desired, in the steam chamber.

Filed: 1921-06-02
Abstract: 186,657. Ransomes & Rapier, Ltd., and Lewis, R. S. June 2, 1921. Jib cranes.-Comprises arrangements of hoisting and luffing gear for cranes of the type in which both hoisting and luffing gears are connected to a single source of power so as to be driven separately or simultaneously, the gearing not in use being automatically braked. In the present construction a driven shaft, normally braked by a stationary member, is coupled to a coaxial driving-shaft, the axial movement of the clutch member progressively releasing the brake and engaging the clutch elements. In the form illustrated in Fig. 1, a worm shaft A<1>, connected to the source of power, drives the hoisting-drum D directly and is fitted with the sliding element C<2> of a friction clutch for coupling it to the coaxial worm shaft B for driving the luffing-drum. The engaging movemsnt of the clutch moves the shaft B axially against the pressure of the load to release the clutch element C<1> from the fixed brake cone C, the brake being re-applied automatically as soon as the clutch is relieved. Preferably the drums are wound so that the raising of the load is accompanied by a lowering of the jib to give approximately horizontal traverse of the load during luffing. A solenoid C<5> may be used to operate the clutch. In a modification, the clutch and brake surfaces are flat discs instead of being conical. In a further modification, Fig. 3, two geared parallel shafts J, K are employed for driving the hoisting and luffing drums respectively, each shaft being fitted with clutch-and-brake mechanism similar to that shown in Fig. 1.
