Title: Arrangement for television signal delay
IPC: H04N5/208
Filed: 1973-07-05
Abstract: 1406364 Television PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 5 July 1973 [8 July 1972] 31986/73 Heading H4F An image signal delay arrangement for a vertical aperture corrector which ensures that the delayed image signal is identical to the undelayed image signal, i.e. which compensates for temperature variations and ageing phenomena of the delay line, e.g. a glass delay line, comprises a modulator 13 (preferably amplitude modulator although reference is made to frequency modulation when magnetic disc or tape delays are used) in which the image signal at input 1 is modulated on a carrier from oscillator 11, the modulated carrier then being delayed 30, e.g. by one line or field period, and supplied via high frequency amplifier circuit 32, demodulator 43, and low frequency amplifier 45 to output terminal 57. In addition the output of the low frequency amplifier 45 is connected to a control circuit 58 (including integrating operational amplifier 61) which clamps the black level of the image signal to a reference potential, e.g. ground, and (as a comparator circuit) applies a control voltage to output terminal 63 which is a function of the difference between the reference potential and the black level in the delayed image signal present during a line blanking period before clamping, this control voltage being applied to the high frequency circuit 32 to stabilize the modulated carrier amplitude applied to the demodulator 43 when the black level is present in the image signal. In operation the circuit is initially adjusted by switching switch 36 to terminal 37 so that transistor 33 conveys a given D.C. bias determining its amplification. Phase shifter 44 is displaced until demodulator 43 provides a maximum output signal which results in an optimum synchronous detection, and then feedback resistor 56 in the low frequency amplifier 45 is adjusted so that the peakto-peak value of the output signal at 57 is equal to that of the input signal at terminal 1. The absolute voltage values are adjusted by resistor 51 until ground potential corresponds to the black level in the output image signal. The input image signal is clamped during the line blanking periods to ground in circuit 3-9. A signal delayed by two line periods may be similarly obtained from the output of operational amplifier 41 using one line period delay line 30<SP>1</SP>, high frequency amplifier 32<SP>1</SP>, demodulator 43<SP>1</SP>, low frequency amplifier 45<SP>1</SP> and control circuit 68<SP>1</SP>. Alternatively one delay line 30 may be used, quadrature modulation being employed for the one and two line delayed image signals. The demodulator 43 is substantially the same as modulator 13 but the current source 18 must be stabilized and resistors 16 and 17 equal.

Title: Improvements in or relating to machines for performing lasting or analogous operations upon shoe parts
IPC: A43D21/12
Filed: 1946-10-29
Abstract: A thick band of viscous adhesive is introduced between the lasting margin of stock and a shoe bottom part by a member arranged to engage the work before the lasting margin is pressed against such bottom part and after the stock has been worked inwardly over the shoe bottom by power-operated means.  Delay in conditioning a previously applied adhesive in cement lasting shoes is thereby avoided.  The invention is described as applied to a machine having a rapidly reciprocating gripper comprising front and rear jaws 12, 10, arranged to act around the shoe bottom in a progressive manner; an edge gauge 20, against which the shoe is held by the operator; a shoe bottom rest 14; presser-foot 16, which presses against the shoe margin and then moves to feed the shoe; and feed-retaining finger 188 all constructed and operated as described in Specification 598,216, [Group VII].  The presser-foot 16 which is vibrated rapidly toward and away from engagement with the lasting margin and feed-retaining member 18 both descend with hammer-like action and serve to press the lasting margin of the upper at different locations progressively against the shoe bottom member as it is fed forwards in the machine, to hold the upper in lasted position.  The shoe bottom rest 14 has a discharge orifice 370 in its shoe bottom engaging face through which <PICT:0618372/III/1> <PICT:0618372/III/2> thermo-plastic adhesive in the form of a thick band is pumped from a container 318 provided with thermostatically-controlled electric heating means.  The bottom rest 14 may be similarly electrically heated, and the arrangement is such that, when the operating treadle is depressed to swing the bottom rest 14 into its operative position and the jaws 10, 12 are rendered operative to grip and draw the lasting margin inwardly from the edge of the shoe, a valve rod 360 is lifted to permit a gear pump, having gear-wheels 346, 348 and driven by a flexible shaft connected to a worm-wheel 380 splined in the shaft 352 on which the wheel 348 is mounted, to draw adhesive in suitable fluid condition through a space 340 in the container and deliver it, through the lower end of a bore 356 and bores 310, 306, 304, to the discharge passage 370 in the shoe bottom engaging face of the member 14.  When the operating treadle is released, the arm 360 is moved down until its lower conical end 362 seats on the upper end of the bore 310 and discharge of the pump is byepassed, through the space between a flattened side 364 of the rod 360 and the bore 356, into the container.  This latter is so mounted as to be tiltable with its support 324 about the screws 326 by which the support 324 is connected to brackets 328 supported on the upper portion 24 of the machine frame, to enable it to be inserted for removal of adhesive therefrom.

Title: Improvements in the production of pleats, folds, tucks, or the like, in, or on, fabrics and apparatus to be employed therein
IPC: D05B35/08
Filed: 1919-12-22
Abstract: 160,549. Tombs, E. S. B. Boys-. Dec. 22, 1919. Sewing - machines; folding devices; feed by clamps; feed by moving machine; feeding long lengths of fabric. Fabric from a roll 3 is led by means of guide-rollers M and a feed roller M<6> past a sewing- machine X. Blades 52 form transverse pleats in the fabric which are stitched in place as a carriage O supporting the fabric and the rollers is moved step by step across the front of the sewing-machine. The carriage O is guided within a box 2 by rollers H and G and is moved transversely by a feed-screw A which is intermittingly rotated by means of a pin wheel 16, Fig. 6, and a continuously rotating cam 14. Clutches are provided for reversing the feed so that pleats can be stitched in both journeys of the carriage. The feed-roller M<6> is turned a suitable distance after the completion of a row of stitches by spur-gearing and a long toothed drum 41 extending from end to end of the box 2. Change-wheels 18 - - 21 and 37 - - 40 are provided to vary the movements of the feed-screw A and the feed-roller M<6>. The blades 52 are reciprocated by slides 55 carrying pins 54 which project through cam-slots in all the blades. The pleats are pressed together and held for stitching by a presser 56 actuated by the parts 58 - - 62. In place of the reciprocating blades 52 a pair of fixed pleating-guides may be used, one for each direction of travel of the carriage, and these are moved into and out of pleating posiiion by cam-gear. All the movements in a sequence of operations are performed automatically by cams and to avoid the use of very large cam discs, the cam shaft 22<a> is driven quickly, when the cams are operating by a fast-running worm 106 and diametrically opposed quadrants of pins 107 on a drum 108, and slowly at other times by a slow-running worm 110 and other quadrants of pins 111.

Title: Improvements relating to conveyors or elevators
IPC: B65G19/16
Filed: 1938-11-05
Abstract: 519,501. Endless-chain conveyers. NEW CONVEYOR CO., Ltd., and HOYLE, H. P. Nov. 5, 1938, No. 32127. [Class 78 (i)] Material is fed from a lower chamber charged through an opening j, and delivered to a shoot k by pivoted carriers m attached at intervals to an endless chain i. On the up-run through the conduit c the carriers are maintained horizontal by projections at their rear edges engaging the rear wall of the conduit. The latter is sloped rearwardly at p to allow the carriers to tilt and deliver the material to the shoot. Positive tilting is ensured by the ramp q. A second ramp s rights the carriers again before they pass the upper sprocket. Contact with the sloping portion of the outer wall of the descent conduit gradually tilts -the carriers again until contact of their rear projections with the inner'wall b can maintain them in the tilted position. Contact with the ramp u once more sets them at right angles to the run of the chain as they pass under the charging opening. A gap between the holding ramps u<1> and v allows the carriers to tilt momentarily again to drop any material they may have collected down to the bottom of the conduit from whence they scrape it up after passing the lower sprocket. The matter claimed in Specification 510,837 is disclaimed in the present Specification.

Title: Measuring apparatus
IPC: G01B11/02
Filed: 1974-10-07
Abstract: 1489181 Measuring feet SHOE & ALLIED TRADES RESEARCH ASSOCIATION 7 Oct 1974 [5 July 1973] 32192/73 Heading G1A Apparatus for measuring human feet senses the length and/or width of the foot, derives a signal electrically from the sensors and indicates an appropriate shoe size.  The apparatus may indicate shoe size by one of several methods. Mondopoint sizes may be displayed as the length in mm and the width in mm multiplied by sin 70 degrees. Separate displays may be provided for each foot or the larger of the length and width values may be taken. For British sizes, the size corresponding to the measured length is obtained from a store and displayed. This size value may be modified if the width falls outside the ranges for the measured size but within the range of an adjacent size. The measuring apparatus comprises a translucent platform 4b with partitions 6 and 8 against which the feet are placed. A line of equally spaced photodetectors 1 1 -1 n  is arranged below partition 6 and a line of photo-detectors W 1 -W n  is arranged on bar 22 between platform 4b and partition 6 for movement by motor 26 in the direction of arrow 32. In operation, a value is pre-set into a length counter and the count is counted down by pulses as photodetectors I are shadowed by bar 22 until any of detectors w are shadowed. The resulting count corresponds to length L. Shadowing of each photocells w sets associated stores and the farthest store to the right as determined by a scanning circuit represents the width. Circuitry is described for modifying the size in accordance with the measured width. The photo-detectors may be laterally positioned to obtain the correct spacing. In an alternative embodiment with a charge coupled photo-diode detector, a lens may be used to give a correct sized image of the foot at the detectors for obtaining the desired resolution.

Title: Improvements in and relating to buoyancy motors
IPC: F03B13/26
Filed: 1920-11-16
Abstract: 154,188. Schultz, E. J. A. Nov. 20, 1919, [Convention date]. Buoyancy motors; tidal energy, utilizing.-A hydro-pneumatic motor is operated by compressed air derived from a tidal energy plant. A wheel formed with blades b fixed on a hollow drum c is completely immersed in water contained in a casing a so that the bearings are relieved of the weight. An inlet e at the bottom of the case and an outlet g at the top are in communication with compression and suction chambers of a tidal energy plant by conduits F and G, Fig. 3. By means of piston valves P, P<1>, the conduit F can be put in communication with a chamber A or B and the conduit G with the chamber B or A; at the same time cylindrical bell valves C, C' allow communication between the chamber A and a channel D open to the tide or a channel D' open to a low-level reservoir E and reversely for the chamber B. At high tide, when the valves are in the positions shown in Fig. 3, there is compression in the chamber A and rarefaction in the chamber B which consequently fill and empty respectively. The valves P, P<1> and C, C' are then reversed so that there is now pressure in chamber B and rarefation in chamber A, the conduits F and G still being the compression and rarefaction conduits respectively. As the tide ebbs, a critical level M<2> is reached due to the height of the water in the casing a; at this point the tide is cut off by a sluice gate N and a reserve of water, accumulated at high tide, in a high-level reservoir K, is used until the tide continuing to ebb, the low-level reservoir E can be used to give the compression. Regularity can be obtained by employing more than one pair of chambers, and effecting the gate operations at different times as nearly as possible after equal periods. Other liquids than water may be used in the casing a and gases other than air may be employed. The peripheral portions of the blades may be formed as shown at m, n, Fig. 2, to facilitate the filling of the pockets at the top.

Abstract: 338,324. Siemens & Halske Akt.- Ges. Oct. 25, 1928, [Convention date]. Semi-automatic exchange systems.-An operator's impulse transmitting set is set by means of tens and units keys Z, E, and sends out a single train of impulses equal to the number keyed. The operation of a tens key connects the relay P to a group of 10 adjacent b-terminals of the sending switch Zg and the operation of a units key grounds a particular set of a-terminals separated from each other by intervals of 10 steps and also closes a contact E whereupon R, An pull up in series and start a ground impulse to the selector W. R also energizes X which locks and energizes stepping magnet D1 of the switch Zg. D1 shunts out R which terminates the impulse and shunts out X whereupon D1 falls and R pulls up again to re-start the cycle. When the required number of impulses has been sent, a circuit via the keys is made on the relapse of X for P which locks and interrupts the impulsing circuit. The switch Zg continues to advance and when it reaches normal P falls back. Prior to sending, the operator presses key A which lights lamp FL if the switch Zg is in its normal position.

In siphon-discharge water-waste-preventers of the kind in which by a single actuation or by two closely-repeated actuations of a single actuating -member, either only a predetermined proportion or the whole of the contents of the cistern can be discharged, the member 62 has associated with it pawl- and-ratchet mechanism, whereby an initial operation of the member operates a lever 32b for starting the siphon to effect a. partial but predetermined discharge, and a second operation, before said partial discharge is completed, operates a second lever 38b which operates means for continuing the action of the siphon to discharge the whole of the cistern contents. In the form shown, the apparatus is of the general kind described in Specification 438,878, _ the lever 32b being connected to the piston-rod and the lever 38b to the chamber 27. The levers 32b, 38b are loosely mounted upon the spindle 64 to which the member 62 is attached, which spindle carries a member 66, Fig. 2, fixed to a spindle 67 carrying pawls 68, 69. When the lever 62 is lowered the spindle 67 is rotated so that the pawl 68 enters a recess 71, Fig. 4, in the end of the lever 32b and rotates it to start the siphon ; the lever 62 being released it returns under the action of a counterweight carrying the pawls with it and causing the pawl 69 to enter a recess 72 in the lever 38b. If the lever 62 be again pulled, the lever 38b is thereupon actuated to lift the member 27 and complete the flush.

Title: Separation of mixtures containing alkyl aluminium compounds
IPC: C07F5/06
Filed: 1962-08-24
Abstract: Mixtures of C1-C3 alkyl aluminium compounds and hydrocarbons are treated with alkali metal cyanides or complex compounds thereof with alkyl aluminium compounds wherein the molar ratio of Me1CN:AIR3, Me1 being an alkali metal and R representing C1-C3 alkyl groups, is at least 1:1.5, separating the resultant complex compounds from the remaining components of the mixture and splitting them by heating into aluminium alkyl compounds and alkali metal cyanides or a lower complex compound thereof. The starting mixture may be any mixture of alkyl aluminium compounds with olefins such as is obtained by "displacement reactions".  Sodium and potassium cyanides are preferred, particularly mixtures thereof. These cyanides form with alkyl aluminium compounds complexes of formula Me1CN:AIR3 wherein the molar ratio are from 1:1.5 to 1:2. Thus the lower complexes may be used in place of the alkali metal cyanides.  The whole displacement product may be treated, or if desired the olefins up to and including C10 may be separated by distillation under vacuum e.g. in a thin film evaporator and to treat the higher olefin-alkyl aluminium mixture with the alkali metal cyanides. Complexing may be carried out at temperatures up to 150 DEG C., in the presence of a solvent if desired.  The a -olefins form a separate upper layer which may be separated by decantation, washed to recover any trialkyl aluminium compounds contained therein and fractionally distilled. The complexes may be decomposed by heating. Specifications 773,536 and 908,032 are referred to.
