Title: Improvements in work-holders for machine tools
Inventor: BRYANT VICTOR JAMES
IPC: B23D37/06
Filed: 1959-10-16
Abstract: 925,177. Broaching. LAPOINTE MACHINE TOOL CO. Ltd. Jan. 16, 1961 [Oct. 16, 1959], No. 35131/59. Class 83 (3). Indexing means for a machine tool workholder 10 comprises means, such as a motor, for moving the holder through the major part of each step and independent means 17 for moving it through the final part. A rotary table with such indexing means may be incorporated in a broaching machine as described in Specification 914,230. When the broach slide has been retracted it operates a switch to energize a solenoid-operated valve causing retraction of a piston 12, Fig. 2. The piston withdraws the plunger 17 from a recessed disc 18 and rocks a lever 19 to disengage a detent 11 from a clutch. The clutch is continuously powered by a motor and rotates the indexing mechanism. A dog 15 rotating with the clutch operates a switch to allow the piston 12 to advance under the pressure of a spring 13. The detent 11 thus stops the rotation after one revolution and the plunger 17 is advanced first by the spring 13 and, as a switch 23 is operated, by fluid-pressure, causing the wedge action of the plunger to position the disc precisely. Switches may be provided to allow several rotations of the clutch before the plunger and detent are engaged. In a modification, a chain conveyer in a machine for broaching workpieces 26, Fig. 3, is indexed by a fluid-pressure operated rack 28 driving through a one-way clutch 31. Fine-positioning is achieved by a plunger engaging a drum 35.

Title: Improvements relating to television pattern generators
Inventor: SCHAFFER JEFFREY
IPC: H04N17/00
Filed: 1958-11-03
Abstract: 878,170. Television. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Oct. 29, 1959 [Nov. 3, 1958], No. 35229/58. Class 40(3) In a pattern generator for a television system utilizing interlaced scanning with a non-integral number of lines per frame the test signal, which produces a "bar" pattern, consists of a pulse train derived via a divider-counter circuit 4 from the line synchronizing pulses. Since, due to the non-integral line-to-frame ratio, this arrangement alone would result in the "bars" occupying different positions in successive frames, an integral ratio between the test pulse train and the frame synchronizing pulses is produced by resetting the divider-counter 4 by means of pulses occurring at the frame synchronizing pulse rate. The division factor of the divider-counter 4 and of the divider-counter 3 which produced the frame synchronizing pulses from the master oscillator 1 may have any desired value and the invention is applicable to any interlaced television system in which the frames have a non-integral number of lines. The divider-counter 4 may comprise an appropriate number of cascaded binary scalers each of which is reset by the positively going portion of differentiated frame synchronizing pulses (Fig. 3, not shown). To produce a pattern which, in the complete picture (= 2 Î frame), has "bars" having a width of two lines the test signal may be derived from the output of a bistable circuit the two states of which are assumed, respectively, under the control of the positively going portions of differentiated line synchronizing pulses and the differentiated test signal pulse train from dividercounter 4 (Fig. 4, not shown).

Title: Improvements in or relating to parachutes
IPC: B64D17/14
Filed: 1954-12-06
Abstract: 756,139. Parachutes. PIONEER PARACHUTE CO., Inc. Dec. 6, 1954 [Dec. 15, 1953], No. 35265/54. Class 4. A parachute canopy 1 which is dome-shaped during descent and has a circular skirt portion with shroud lines 6 depending therefrom, is characterized in that one or more inflatable and collapsible guide members 12 are provided at or near the skirt, each comprising an upwardly and outwardly inclined panel 9 and an inverted U-shaped portion 8 extending between the canopy and the panel, and defining therewith a space communicating with the interior of the canopy, the sides of the U-shaped portion 8 being inclined to the vertical so that the force of the airstream on these sides produces a lateral tangential component. In Fig. 1, guide members 7 are provided at uniform intervals, and a pair of diametrically opposite members 12 have slanting sides. The pair may slant in the same direction, so that the rotations each produced on the canopy cancel out, but their translational forces are additive. Alternatively, they may slant oppositely, so that no translative force results, but the canopy is set in rotation. Each pocket 12 may be collapsed by the user by pulling a cord 15 running through an eye 17 and secured to the interior of the pocket, so that the user can control the rotation and translatory movement of the parachute. In a modification, each of the pockets 12 are replaced by a pair of such pockets, as in Fig. 6, where curved fabric members 28 are added, being secured to the U-shaped member 13b along one edge, and restrained by a cord 29 at the other, thus preventing the air stream from flowing over the top of the U-shaped member 13b, and tending to reduce the effect. In Fig. 8, the guide members are set further up the skirt, for which purpose the canopy is cut away at 30 to match the portion 26, which will become U-shaped when attached to the panel 23. The guide members may be vented, as shown at 11, Fig. 1, or may be of different porosity in different parts as shown by shading, Fig. 8. Reference has been directed by the Comptroller to Specification 703,026.
Patent GB-1444187-A (GB)
Title: Multistrand threads
IPC: D02G3/46
Filed: 1973-07-25
Abstract: 1444187 Covering cores K P BIERER 24 Oct 1974 [25 July 1973] 35388/73 Heading B8G [Also in Divisions D1-D2] Yarn comprises three strands e.g. of monofil, multifilaments and/or staple fibres of natural, synthetic, metal or glass fibre materials. The first strand extends along the length of the yarn and the second and third strands lie helically therearound in opposite senses, crossing one another and with the second and third strands alternately on the outside. The two helices may be of equal pitch so that the crossover points of the second and third strands are alternately on opposite sides of the first strand. In the apparatus shown, strands 10, 11, 12 are supplied from spools 20, 21, 22, the latter two on fixed supports, so that the strands are drawn upwardly through tubular elements 23, 24, mounted in a fixed plate 25 to be driven rotatably in opposite directions at equal speeds about vertically closely-spaced axes from a shaft 26 through bevel wheels 28 and pinions 29, 30. Guides 23, 24, lead into tubular guides 31, 32, into which strands may be threaded through slots 33. Guides 31, 32, at their upper ends lie just outside the periphery of plate 34 and rotate therearound passing one another twice each revolution at diametrically opposite locations. The first strand is led from spool 20 over tensioning device 35 and this taut strand is combined with second and third strands carried by guides 31, 32, at a point below an aperture 36 in a guide 37 through which the assembled yarn passes to be wound on a take-up spool 38 (also drawn from shaft 26). The second and third strands extending upwardly from guides 31, 32, form helices (around the first strand) in opposite directions and with the second strand passing alternately inside and outside the third strand and, since guides 31, 32, have to be mounted below plate 34, they are required to pass through the support therefor. The latter may be enabled by use of magnetic or air levitation means (not shown): however, in the mechanism shown, a support structure 56 for plate 34 comprises two pairs of freely rotatable rollers 57, 58, and 59, 60 engaging similar rollers 50, 51, driven (as by belt 42, pulleys 54, 55, on shafts 52, 53) in opposite directions in synchronism with the rotation of guides 31, 32, whereby the latter, in operation and whilst rotating, pass through moving shaped helical slots 61 of rollers 50, 51, in arcuate paths thereacross.

Title: Resistance networks for stabilizing phase shift in resolvers
IPC: G06G7/22
Filed: 1960-10-17
Abstract: 899,986. Electric analogue computers. COMPUTING DEVICES OF CANADA Ltd. Oct. 17, 1960 [Oct. 21, 1959], No. 35513/60. Class 37. [Also in Group XL (b)] In order to compensate for changes with temperature of the winding resistance Rw of a synchro, which cause phase variation (with temperature), in the synchro output voltage a network of resistance RN including a temperaturevariable resistor RT, e.g. a thermistor (Fig. 5) is provided in the synchro input, the transfer function at any temperature over a desired range then being shown mathematically in the Specification to be constant when RN+RI is constant (where RI represents the real part of the winding impedance and is equivalent to Rw). Other compensating circuits using one or more thermistors (Figs. 8, 10, 12, not shown) are described. In the embodiment of Fig. 6, A.C. voltages representing three sets of cartesian co-ordinates x1, y1, x2, y2, x3, y3 are summed and resolved by a synchro resolver YT into a vector of range So and bearing #. A motor 18 drives the rotor of YT and of a temperaturecompensated synchro YR until both rotors are set at an angle #, when the outputs across potentiometers 13, 14 are k Vi sin #, k Vi cos #, respectively, and a motor 17 drives the wiper of these potentiometers until there is no input to the amplifiers 19, 20 and therefore none to the stator windings 21, 22 of resolver YT when the amount of movement of the wipers will correspond to the range So. The use of synchro YR ensures that the outputs from 13, 14 are phase advanced for a given temperature and capacitors C2, C3 can then be chosen so that the feedback voltages to the amplifiers 19, 20 can be brought into precise anti-phase relation to the input voltage.

Title: Improvements in or relating to spring suspension systems of vehicles
IPC: B60G17/015
Filed: 1936-12-30
Abstract: 488,037. Vehicle suspensions. NEWTON, N. B. Dec. 30,1936, No. 35677. [Class 108 (ii)] In an arrangement for checking the roll of motor or like road vehicles during steering movements, actuation of the steering mechanism automatically effects a stiffening of the appropriate shock-absorbers on one or other side of the vehicle, the extent of the adjustment being dependent upon the vehicle speed or engine revolutions, and also, if desired, upon the degree of movement of the steering controls. In the arrangement shown in Fig. 1, pressure is developed in an oil circuit including a reservoir b, a toothed-wheel pump a driven by the engine, and an adjustable return passage h. The circuit is coupled to two cylinders c, d fitted with spring-controlled plungers g and valves g<2> which normally close passages c<1>, d<1> leading to the shock-absorbers on either side of the vehicle. When the steering-arm e is displaced, one of the plungers g is operated against the action of its control spring and pressure is admitted to the associated shockabsorbers, additional return valves c<2>, d<2> being fitted to release the pressure when the arm e is returned to its central position. In an alternative arrangement the operating member e is mounted upon the track-rod of the steering mechanism. By tapering the valves g<2> or providing them with tapering grooves, the adjustment of the shock-absorbers may also be made dependent upon the extent of movement of the arm e. In a modification, Fig. 4, a dash-pot including a reservoir q with a restricted orifice p is inserted between the operated plunger n and the control valve o for the shock-absorbers, with the result that an increased stiffening of the shock-absorbers occurs during a sudden movement of the steering mechanism.

G., and SCAMMELL LORRIES, Ltd., 52, High Holborn, both in London. Dec. 19, 1933, No. 35712. [Classes 78 (ii) and 78 (iv)] [See also Group XXXII] In vehicles for transporting refuse bins and other containers means are provided on the vehicle for selectively drawing the bins &c. on to the vehicle at a number of points and for selectively lowering them from such points and means are also provided for hauling the bins &c. up a ramp or ramps and for tipping the bins to discharge their contents. As shown, the bins are provided with rear wheels 6 and a front caster wheel 6<a> and are adapted to be engaged by a hauling device 11 whereby they may be drawn on to the vehicle by means of a ramp 7. The hauling device 11 is mounted at one side of the vehicle upon a carriage 12 adapted to traverse to any selected position on a longitudinal girder 15 by means of rollers &c. and comprises an hydraulic cylinder 13, ram 28 and a sliding beam 23 which is spring controlled by springs 13b mounted in columns 13<a>. In the arrangement shown, two bins &c. may be simultaneously dealt with and accordingly a cable 27 has its two ends provided with hooks &c. 31 and passes through abutments in brackets and under pulleys 32 on the carriage 12, over pulleys 35 on the ram and under a centre pulley 37 mounted on the slide 23. To draw the bins on to the vehicle the slide 23 is wedged or locked and the ram lowered to permit the ends of hooks 31 to engage the two bins whereupon on raising the ram 28 the bins are drawn up the ramp 7 on to the vehicle which is provided with transverse rails or guides. To lock the bin in position an incline 45 is provided, up which the rear wheels are partially drawn and over a spring-controlled catch 44 provided with a horn 44<a> for this purpose. When the bins are released these catches 44 engage the wheel axles and cannot release them until the bins are again drawn slightly forward by the hauling mechanism. The front wheels 6<a> are locked by an arm 48. The ramp is engaged in a longitudinal groove 9 which also serves for locating the shoot or plate 10 over which the contents are discharged when the bins are tipped. In tipping the hooks 31 engage their abutments and movement of the ram therefore moves the slide beam 23, the abutments 24 of which engage abutments 21 on the ends of the bins and cause them to tip as shown in Fig. 3, lower abutments on the beam 23 engaging members 25 to limit the tipping and members 24b hooking over the members 21 to prevent disengagement. The hauling cylinder 13 &c. is pivotally mounted on the carriage 12 and is connected by flexible conduit 43 to telescopic conduit 41 on the side of the vehicle. This latter conduit is connected to the pump &c. by flexible conduit 40.
