Title: Improvements in fluid pressure operated braking apparatus
Inventor: BALLARD DONALD HENRY
IPC: B60T13/44
Filed: 1960-06-08
Abstract: 942,402. Fluid-pressure controlled brakes. CLAYTON DEWANDRE CO. Ltd. June 21, 1961 [June 8, 1960], No. 20124/60. Heading F2F. A braking apparatus for motor vehicles comprises an air - pressure - operated system for actuating one set of brakes, an air-pressure-boosted hyraulic system for actuating another set of brakes, and common pedal-operated means for actuating the control valve of the air pressure system and the master cylinder of the hydraulic system. As shown, a boosted hydraulic system for operating the front wheel brakes includes a servomotor 1, a control valve 2 and an hydraulic output cylinder 3 from which a conduit 4 leads to the wheel brake cylinders, compressed air being admitted to the servomotor by way of the valve 2 from a conduit 5 connected to a reservoir 6 which, or a supplementary reservoir, may be combined with the servomotor. The servomotor hydraulic cylinder unit is of the type wherein the servopiston has mechanical connection with the hydraulic cylinder piston and in which pressure generated in the master cylinder 7 is transmitted through conduit 8 to a plunger which actuates the valve 2 and also to a space behind the piston in the hydraulic cylinder such that normally the latter transmits the output of the servomotor and of the master cylinder 7 to the wheel brakes, but transmits the pressure generated by the cylinder 7 alone in the event of a failure of the compressed air supply. The cylinder 7 is actuated by a foot pedal 9, a " pulltype " valve 13 being interposed in the rod linkage 10 and controlling the flow of compressed air to the rear brake power unit 14 from a reservoir 15; depression of the pedal effects generation of the master cylinder pressure to operate the front brakes and simultaneous admittance of air pressure to the unit 14 to operate the rear brakes. In a modification, the rod and lever system 10, 11 and 12 and valve 13 are replaced by a beam to which the pedal 9 is connected, the ends of the beam being connected respectively by rods to the cylinder 7 and a push-type brake valve controlling the flow of compressed air to the unit 14. Specification 854,491 is referred to.

Title: Improvements in or relating to articles comprising rubber bonded to fabric comprising cords of or containing artificial silk and a process for the production thereof
IPC: B60C9/00
Filed: 1937-07-23
Abstract: Fabric comprising cords of or containing artificial silk is bonded to rubber by the solids deposit of a rubber dispersion containing a proteinous material and carbon black.  The proteinous material may comprise casein, glue or gelatine.  The carbon black is preferably derived from a dispersion of whole tyre reclaim, which is mixed with latex; or the carbon black may be separately dispersed with soap or the like and added to the latex, in which case a dispersion of other types of reclaim (e.g. tube reclaim) may also be added.  In an example, artificial silk cords are drawn through a bath of the dispersion and wound spirally, touching each other on a duck liner on a drum, and are then dried.  Plies are made by coating the cord side of the fabric with rubber stock in a calendar, stripping the duck liner, and coating the other side. Flexing and adhesion tests are described.  Specification 178,811, [Class 140], is referred to.

Abstract: 641,534. Prepayment gas meters. METERS, Ltd., and MAHER, D. P. July 31, 1948, No. 20437. [Class 27] A one-way drive between the metering and quantity mechanisms, enabling the gas valve to be closed manually independently of the metering mechanism, comprises an epicyclic gear having planet pinions h a loose fit on pins g of the planet carrier f, f' which has fixed abutments k which can be engaged by the planet wheels. In the mechanism shown, the sun-wheel i of the epicyclic gear is driven by the metering mechanism through a shaft j, whilst the planet carrier drives the quantity differential d through a worm a, the shaft n of which has a wheel e for zeroising the quantity differential independently of the meter. Rotation of the sunwheel i by the meter moves the planet pinions h bodily into engagement with the abutments k of the carrier; the epicyclic is locked and transmits the drive directly from the meter shaft j to the worm shaft n. When, however, the shaft n is turned by the wheel e, the planet pinions h and abutments k separate so that the pinions are free to turn on their pins g without driving the sun-wheel i. The two abutments k shown are so disposed as to be alternately effective upon successive half tooth-pitch rotations of the planet pinions. The planet carrier may, alternatively, be the driving and the sun-wheel the driven member of the epicyclic gear.

July 19, 1932, No. 20459. Convention date, July 31, 1931. Addition to 319,032. [Class 40 (iii).] The parent Specification describes a system in which dots are suppressed by a filter at the transmitting station, in order to prevent cumulative unbalance due to ferromagnetic dissymmetry between a loaded cable and an artificial line ; and the revised signals are sent on by a pair of contact-making relays. According to the present Specification the contact-making relays feed the cable through a distributer which reshapes the signals, and are arranged as storing relays in a multiplex system. Three transmitters TA, TB, TC feed three pairs A, B, C of storing relays through a distributer 14, dot-suppressing filter 15, and distributer 16. The armatures when idle are in the position shown. When a positive impulse is sent on from transmitter TA to the upper windings of relays A, both armatures a1 a2, are set to the left, or by a negative impulse both are set to the right. Positive or negative polarity, as the case may be, is therefore impressed on the appropriate segment of distributer 18 and is sent on to cable 20 through brush 24 during the next subsequent signal period (i.e. two segments later). During the following signal period (i.e. four segments after the operation of the relays A) current from battery RB is supplied through brush 23 to the lower windings of these relays, which are wound in such senses that the armatures resume the positions shown. The pairs A, B, C act in turn upon successive impulses. A similar arrangement may be adopted at a retransmitting station (Fig. 2, not shown) and switches are then employed for connecting one cable to an input terminal and the other to an output terminal of the symmetrically arranged repeating system.

IPC: A61F2/64
Filed: 1919-08-21
Abstract: 134,185. Desoutter, C. Aug. 21, 1919. Limbs, artificial.-The freedom of movement of a knee-joint is controlled partly automatically by the weight on the limb and partly mechanically at the will of the wearer. The leg and thigh members of the limb are formed with hemispherical friction surfaces e, h which are adjusted relatively to each other by the movement of the knee-joint pivot f in inclined slots j on the thigh. When the weight comes on the limb, the pivot f moves upwardly in the slots by compressing rubber blocks r against the upper end of the hookshaped lever p. By suitably actuating a rod m, the eccentric k<2> can be operated to move the lever p axially, and thus force the surfaces e, h into any position between the limits of complete freedom and absolute locking of the knee-joint. The pad d assists in maintaining the friction between the surfaces. By rotating the lever p against the action of the spring s through the medium of the knob x, the leg can be removed bodily from the thigh for repair or renewal. The mechanical operating-means for sliding the pivot f may be varied, or even omitted in some cases.
