Title: Improvements in or relating to phonographs
IPC: G11B33/06
Filed: 1954-07-07
Abstract: 792,100. Phonographs. KENT, A.. H. July 7, 1954 [Aug. 7, 1953], No. 19918/54. Class 40 (2). A phonograph for use in a toy or in advertising and which is stated to play in all attitudes including inversion comprises a first biasing spring 65 to provide on the stylus 14 of a sound reproducer unit 15 groove tracking pressure in a lateral direction radially outwardly of a record disc 12 carried by a turn-table 10 rotatably mounted in a frame plate 16, a second biasing spring 59, 60 urging the stylus downwardly towards the record for maintaining contact with the record groove 13 and a resetting mechanism operable by a manual control member. at least at the end of play to pivot the unit upwardly away from the record thereby to allow the first spring 65 to return the unit outwardly to a position where its stylus is. automatically located for re-engagement with the commencement of the groove; actuation of the manual control member initiates an automatic cycle of sound reproduction at the end of which the phonograph automatically stops ready for another cycle or re-actuation of the control member. As shown, the unit 15 is supported via rubber grommets 48 by a resilient A-shaped frame 45 whose apex is welded to a pin 51 pivotable in a bracket 46 in turn pivotable about a pair of spherical bearings 58 located in the plate 16, and the first spring 65 acts torsionally between the bracket 46 and an arm 43 which is also secured to the frame 45 while the end 60 of the second spring 59 both holds the bracket assembly into engagement with it pivoting bearings 58 and produces the downward bias on the stylus 14. Movement of bracket 46 is limited by a recess 90 in the plate 16. The turn-table 10 is driven via a pivotally-biased idler 21 by the shaft 20 of an electric motor 19 supported by brackets 22, 23 and a vibration damping rubber grommet 24 from the plate 16. The motor is supplied from two serially-connected batteries 29 via a switch 41, 42 of which the moving contact 42 is actuated by the leg 43b of the arm 43, whereby the motor is switched off when the stylus reaches the end of the record groove 13. The phonograph remains in this condition until by a,push button or other. manually depressable member outside the phonograph an arm 81 is depressed which in turn depresses an arm 70 on the bracket 46. This lifts the stylus from the record whereupon spring 65 returns the unit 15 until the latter is stopped by engaging the side of the photograph casing 80 which so guides the unit 15 on subsequent release of the push-button that the stylus engages the cornmencement of the groove 13. Reference has been directed by the Comptroller to Specification 725,755.

Title: Spray Foam Insulated Pipe
Inventor: BAUER RICHARD HENRY
IPC: B29C44/12
Filed: 1967-05-01
Abstract: 1,176,418. Insulating pipes; pipe Joints. ESSO RESEARCH & ENG. CO. 1 May, 1967, No. 20015/67. Headings F2G and F2P. In a method of applying foam plastics, e.g. polyurethane; insulation 32 to a pipe section, the constituents of a foamable plastics material is sprayed on to the cleaned exterior of the pipe section, and a vapour barrier coating 12 of bitumastic material is applied prior to foaming of said constituents being completed to provide a denser plastics surface skin layer. The pipe section 10 passes through a cleaning station 14 and a heater 16 prior to passing through a foam-plastics spray chamber 20 applying the foamable plastics to the rotating pipe section. The pipe section is then advanced to a twostage bitumastic spray unit applying a mastic primer layer and a denser layer to the applied foamed plastics layer whilst the latter is still tacky to produce a thickening of the insulation skin. The pipe section is then wrapped with Kraft paper at winding station 28. A control arrangement 30, which may include mechanical, optical or electrical sensing devices for determining the position of the pipe section ends, is effective to stop and start the application of the foam insulation, bitumastic and paper winding at appropriate points adjacent the ends of the pipe section to leave pared ends, which are then butt-welded at 38 to adjacent insulated pipe sections, The bared welded joint may then be insulated. A sheet 42 of galvanized iron is cylindrically wrapped around the joint on the ends of the sprayed insulation layers 32, which terminate in convex rounded end portions 40, and is secured by metal straps 44. Foamable liquid polyurethane 48 is then poured into the void to fill the same. A suitable waterproof mastic is then applied to the insulated joint, the wrapped iron sheet 42 being left in position or removed prior to the mastic application. Adjacent pipe sections may be temporarily joined prior to passing through the various method steps by a coupling 50, Fig. 3 (not shown), comprising interengageable tubes 52, 54, each tube carrying at one end a resilient disc 60 between a fixed plate 58 and an axially movable plate 64 insertable into the end of the associated pipe section. The said end of each tube is inserted into the associated pipe section and the resilient disc expanded into clamping contact with the pipe wall by axial compression between the plates 64, 58, plate 64 being moved towards plate 58 on rotation of a threaded bolt 62. The free end of tube 52 is then slid into the tube 54 and connected thereto by a bayonet connection 68, 70.

Abstract: 244,371. Taylor, C. Aug. 11, 1925. Registering webs.-Apparatus for stretching fabrics, more particularly for use in mercerizing- machines, comprises a number of cylindrical scrolls 9 of the kind having spiral grooves 11 extending from the centre to each end, these scrolls being arranged in an arcuate or circular row with unoccupied spaces between them and being driven to rotate about stationary axes or to revolve about a common axis, or to both rotate and revolve, tension rollers 20 being arranged at both sides of the row to retain fabric passing over the scrolls in tension therewith.

Title: Two level signal extraction circuit
IPC: G06T1/00
Filed: 1974-05-08
Abstract: 1442445 Bar code reader INTERNATIONAL BUSINESS MACHINES CORP 8 May 1974 [22 June 1973] 20264/74 Heading G4M [Also in Division H3] A binary data thresholder, e.g. for an optical bar code-reader, comprises two follow-and-hold circuits which after a respective data transition follow the positive and negative signals respectively and hold the maximum value on detecting a peak and means to provide a thresholding voltage from the two maximum values. The circuit described also includes resetting means for the follow-and-hold circuit if an excessive gap occurs between the signal. In Fig. 4 thresholding of the signals at 60 is effected in a comparator 62 which receives the input signal F(t) and a thresholding voltage Vth equal to the mean of the preceding positive and negative peak values obtained from follow- and-hold circuits 72 and 74. Circuit 72 follows the input signal when a differentiator and a slope detector 92, 100 detect a positive slope above a given value to provide one input to an AND circuit 106 and when following negative-to-positive transitions of the thresholder output at 70, a positive signal is provided at the other input of the AND gate. At the peak of the signal the differentiator output goes to zero, the AND gate is therefore not satisfied and circuit 72 holds the peak value. Circuit 74 correspondingly follows and holds the negative peak. Output signal transitions trigger a monostable circuit 128 which disables a clock oscillator 130 if signals are absent for more than the monostable circuit period, and the clock provides pulses for periodically resetting the follow-and-hold circuits. Correct operation at the first code bar may be assisted by a dummy initial mark or by a scanning probe reset switch. The positive follow-and-hold circuit 72<SP>1</SP>, Fig. 6, comprises s transistor gate 152<SP>1</SP> which, in the follow mode, connects the signal at 60<SP>1</SP> to a storage capacitor 146. To prevent an output transient when the gate is driven off, due to the self capacitance of the FET, a compensating pulse is applied to the storage capacitor via a further capacitor 156<SP>1</SP>, the compensating pulse occurring before the gate turn-off pulse and while the transistor is conducting. The compensating pulse for the negative follow-and-hold circuit 74<SP>1</SP> is applied to the gate via a delay circuit 165-172 to prevent the effect of oscillation. The storage capacitor of the follow-and-hold circuit could be replaced by an inductor circuit (Fig. 8, not shown) or by a storage CR tube.
