Title: Improvements in or relating to adjustable chairs, medical and other couches, and operating and other tables
IPC: A61G15/00
Filed: 1937-11-26
Abstract: 506,397. Surgical chairs. FIDDIAN, J. V. Nov. 26, 1937, No. 32610. [Classes 52 (ii) and 52 (iii)] A chair intended for use in obstetrics comprises a stand 1, 4, Fig. 1, carrying a horizontal shaft on which is tiltably mounted the chair proper comprising a back portion 20 and a seat portion 23, the whole of the chair being adapted to be tilted about the shaft to any angle, and the angle of the back relative to the seat being adjustable, clampable friction discs being provided to secure the chair in adjusted position. The stand comprises a U-shaped frame 1 of metal tube the upper ends of which are secured to dished friction discs 2, and a U-shaped frame 4 the upper ends of which are secured to flanged collars 6, the frames being connected by pivoted links 7. Each disc 2, Fig. 3, has a boss 8 which rides loosely on the collar 6, which in turn rides loosely on a boss 9 mounted slidably and rotatably on a cylindrical head 10 secured to one part of a two-part shaft 11, the two parts of which are connected together by screwed parts 12, 14. The outer part 15 of the head 10 has flats to engage a handle 17. Rotation of the handle in one direction draws the upper parts of the frame together. The boss 9 carries a disc 18 having friction linings 19 which fric- , tionally engage the disc 2 on one side, and discs 26 on a tubular cross member 27 on the other side. The chair back comprises a U-shaped frame 20, Fig. 1, the ends of which are secured to sockets on the discs 18, and a seat part 23, the side members of which are secured at the rear in sockets 25, Fig. 3, on the discs 26. Increase of pressure on the friction discs thus secures both seat and back in any position, but they may be secured in a predetermined relation by means of spring pins 28 on the discs 26 which engage holes in the 'disc 18. Similarly spring pins 30 on the disc 2 engage in holes' in the disc 18 to lock the back relatively to the stand. The seat back is provided with upholstery, preferably removable, e.g., a bag-like cover, and the seat may have any form of supporting surface, but preferably two wide bands 31, Fig. 4, are secured to the bottom of the back and are normally crossed, passed over the front bar 24 of the seat frame and secured to the sides 23 thereof. For certain operations, these bands are drawn up between the limbs of the occupant, passed outwardly over the thighs, then downwardly and secured to the frame side members. A tubular leg rest frame 34 is adjustably mounted on the front of the seat frame: The Provisional Specification states that the invention is applicable to adjustable seats and couches and to operating and other tables.

Title: Hydraulic devices for controlling the speed of wheeled vehicles
Inventor: LITTLE COLIN ROBERT
IPC: B61J3/08
Filed: 1965-07-30
Abstract: 1,136,566. Propelling vehicles. DOWTY MINING EQUIPMENT Ltd. 21 July, 1966 [30 July, 1965], No. 32685/65. Heading B7L. [Also in Division F2] A telescopic hydraulic device for fixing adjacent a track 13 and which is engageable with the passing wheels of a rail vehicle to effect retardation or acceleration thereof comprises a piston 14 and cylinder 11 defining a chamber 19, 25 which communicates with a low pressure connection 22 through a pressureresponsive valve 24 carried by the piston and with a high-pressure connection 32 through a mechanically-operated valve 33 carried by the cylinder, the latter valve being actuated by an hydraulic telescopic tappet 45, 54. Extension or collapse of the tappet is controlled by either a vent valve 56 or a lock valve, which is constituted by an orifice 49 normally closed by the end of a relief valve piston 43 within the pressure responsive valve. On depression of the piston 14 by a vehicle moving below the critical speed, valve 43, 49 remains closed and maintains the tappet fully extended. Valve 24 initially remains open. The lower end of the tappet engages a cup 66, Fig. 3, and compresses a spring 68 until the action of ball detent 63 is overcome and sleeve 59 of the mechanicallyoperated valve 33 released. The compressed spring then urges the sleeve downwards until parts 64 and 65 of said sleeve and a spigot part 34 of the valve become aligned to allow highpressure flow from connection 33 to enter chamber 19. The piston is forced upwardly to exert an accelerating force on the vehicle, the valve 24 closing and lock valve 43, 49 opening to permit collapse of the tappet on upward piston movement. A ring 57 secured to the piston, Fig. 3, engages a flange 60 on the valve sleeve 59 and lifts the latter to its previously closed position shutting off the highpressure supply towards the end of the piston extension stroke. If the piston is depressed by a vehicle moving above a critical speed, pressure responsive valve 24 is closed by the pressure differential due to flow through it, valve flange 42 moving from the larger 37 to the smaller 36, of two stepped bores in the piston wall. Further flow from chamber 19, 25, now at high-pressure and producing a retardation on the vehicle, takes place through a flap non-return valve 27, 28. Large back pressure may raise the relief valve piston to produce a by-pass passage through valve 24 and to vent the tappet, thereby preventing actuation of the mechanically-operated valve on contraction of the piston and cylinder. The vent valve 56 is provided to permit collapse of the tappet in the event of failure of the highpressure source to cause closure of valve 24 and opening of the lock valve.

Abstract: 352,857. Control of several motors. INTERNATIONAL GENERAL ELECTRIC CO., Inc., 120, Broadway, New York, U.S.A.-(Assignees of Allgemeine Elektricitõts-Ges.; 2, Friedrich Karl-Ufer, Berlin.) Oct. 30, 1930, No. 32693. Convention date, Oct. 31, 1929. [Class 38 (iii).] A series of motors m1, m2, such as those driving conveying belts, are automatically started in succession to prevent overloading the supply, some characteristic of each motor, that indicates its speed, is used to effect the starting of the next in the series. Closure of a pushbutton e causes contactor S1 to close. When the motor m1 has reached about 70-80 per cent of its normal speed, the relay W1, due to the decrease in stator current, closes its contacts and causes contactor S2 to close. Alternatively the speed can be determined by rotor voltages or by centrifugal switches. If star-delta starting is used, each relay W is only operative in the delta position, similarly if automatic starters for each motor are used, each relay W is only operative after the final contact of the starter has closed.

Title: A process for the manufacture of gasoline
IPC: C10L1/06
Filed: 1946-11-18
Abstract: Leaded gasoline having a desired A.S.T.M. octane number (N1) is manufactured from a thermal gasoline stock having an A.S.T.M. octane number (N) by hydrogenating the stock until its percentage saturation (S), i.e. the per cent decrease in bromine number due to hydrogenation, equals 11+4.7 (N1-N)\sBX, where X has any value not exceeding 5, and then adding tetra-ethyl lead.  The hydrogenation may be carried out at a temperature between about 400 DEG  and 850 DEG F., and a pressure between 100 and 1000 lbs./sq. in.  The percentage saturation may be controlled by adjusting the space velocity either alone or in combination with the hydrogen pressure.  In an example, a pressure distillate fraction having an octane number 73.8 is hydrogenated with a nickel sulphide-tungsten sulphide catalyst (in which the nickel sulphide is predominant) at 700 DEG  F., 700 lbs./sq. in. pressure, recycled gas (largely hydrogen) to hydrocarbon feed molecular ratio about 7 : 1 and a liquid hourly space velocity varying between 10 and 55.  The maximum octane number before the addition of T.E.L. occurs at 8 per cent saturation, but the optimum saturation for final octane numbers 77 and 75 after addition of T.E.L. is about 27 per cent and 14 per cent respectively. Molybdenum sulphide, tungsten sulphide promoted with a sulphide of iron, cobalt or nickel, and cobalt molybdate are given as examples of alternative hydrogenation catalysts.  The hydrogenation may be carried out with the gasoline stock in the vapour, liquid or mixed phase. Specification 333,511, [Class 32], is referred to.

Abstract: 619,093. Inductor alternators. BENDIX AVIATION CORPORATION. Nov. 19, 1946, No. 34304. Convention date, Dec. 21, 1945. [Class 35] The stator of an inductor alternator having a single toothed rotor is axially divided into two parts, an auxiliary part which is permanently magnetized and a main part composed of normal magnetic material and excited by the auxiliary part. In one form, Figs. 1 and 3, the main part 2 and the auxiliary part 3 are separated by a non-magnetic spacer 4 and are both of similar form having poles with teeth 5, 7, 9 and 6, 8, 10 respectively which carry three-phase main windings 11, 12, 13 and auxiliary windings 14, 15, 16 in which the exciting current is generated. A further field coil 17 is wound round the poles of both stator parts. In Fig. 8 (not shown), a control circuit is illustrated in which the windings 14, 15, 16 feed the field winding 17 through a polyphase rectifier. When it has built up, the voltage of the main windings 11, 12, 13 then feeds a further rectifier through a transformer, and this exciting current, which is controlled by a carbon-pile regulator operated by the output voltage of the machine, is added to that supplied by the auxiliary windings 14, 15, 16. In a modified form of the invention in which the laminµ are secured together by rivets, the windings are held in place by bent-up tabs on the stator end plates corresponding to the teeth. In a further modification, the auxiliary windings are dispensed with and the main generator winding is taken round the poles of both stators. A control circuit having a transformer fed rectifier supplying the field winding 17 through a carbon-pile regulator is described for this arrangement, condensers being used to correct the power factor of the load current. A further control circuit is described in which the generator output is rectified to charge a battery, the generated three-phase voltage being used to operate a cut-out relay controlling the carbon-pile regulator. Specifications 398,650, [Group XXIV], and 608,508 are referred to.

Filed: 1956-11-09
Abstract: 841,624. Sawtooth generating circuits; cathoderay tube circuits. PHILCO CORPORATION. Nov. 9, 1956 [Nov. 14, 1955], No. 34305/56. Classes 40(6) and 40(7). In a linearizing circuit for a sawtooth wave for a cathode ray tube, variations of the deflection coil flux from a constant reference level are prevented by comparing the voltage produced across the deflecting coil with a constant voltage and maintaining their equality. Fig. 1 shows a circuit in which a voltage 15 is applied via a driver stage and transformer to the line deflecting coils 13 of the cathode ray tube 14 of a television receiver. A flux clamp circuit 16 comprises a coil 17 coupled to the deflecting coil 13 so that the voltage produced across this coil is compared with a D.C. reference voltage from battery 19 and determines the conductivity of diode 18. The polarity of diode 18 is such that it conducts only during the sweep interval and only when the voltage across coil 17 exceeds that of battery 19. Under these conditions the coil 17 is effectively short-circuited heavy current flows in the flux clamp circuit and produces a retroactive flux change in coil 13 to maintain the current change substantially linear with time. The impedance of coil 17 and diode 18 are fairly low in value. The coil 17 may be placed inside and parallel to the associated deflecting coils 13 within the deflection yoke and there may be two coils connected in series or parallel with the coils 13. A section of the auxiliary coil 17 may not be coupled to the deflecting coil 13, Fig. 3, (not shown). As shown in Fig. 4 two auxiliary coils 26, 27 are partly inside and partly outside the deflection yoke, the extending portions of the coils while not coupled to the deflecting coils are closer to the gun of the cathode ray tube and have more influence on the beam. As shown in Fig. 5 four auxiliary coils 29, 30, 31, 32 are shown two inside and two outside the yoke each pair of coils being series connected. The auxiliary coils may be wire wound or formed by printed circuit technique. The battery 19 may be replaced by an RC circuit.
