Title: Improvements in or relating to engine-assisted pedal cycles
IPC: B62J17/00
Filed: 1956-08-20
Abstract: 798,714. Weather-shields and foot-rests for motor-cycles. KREIDLER, A. Aug. 20, 1956 [Aug. 24, 1955], No. 25317/56. Classes 136(1) and 136(3) An engine-assisted pedal cycle of the type having a pedal crank drive comprises a leg shield arrangement which includes a splash guard extending below the pedal crank drive and adapted to be resiliently deflected upon rotation of the pedals so as not to impede the movement of the pedals. As shown in Fig. 1, splash boards 4 are suspended on either side of a cycle frame 3 by arms 5, 6, one arm 5 being mounted on the pedal crank shaft 2, whilst the other arm 6 is linked to the rear wheel fork 7. Each splash board 4 is held in its normal position by means of a return spring 9. Pedal crank arms 11 are each provided with a pedal 12 fitted with rollers 13 on its lower side. On depressing one of the pedals the rollers 13 strike against the splash board 4 and force it downwardly. The device is arranged so that swinging movement of the suspension arms 5, 6 is effected in the same direction as the movement of the pedal crank arm 11. When the pedal has passed its lowest position, the splash board 4 rises under the influence of the spring 9 into the starting position where it abuts a stop 10 on the gear box 1. In a modification shown in Fig. 3 a control cam 14 is mounted on each side of the pedal crank shaft and a control finger 15 abuts the cam 14. This arrangement prevents the board 4 from swinging up and down in the event of small involuntary movements of the pedal cranks 11. In a further modification the splash guard is made in three sections hinged together. Alternatively, the splash guard may comprise a flexible belt or a rubber band.

Title: Improvements in or relating to gear pumps
Inventor: JUBB ALBERT
IPC: F04C15/00
Filed: 1952-10-13
Abstract: 732,141. Gear pumps. ROLLS-ROYCE, Ltd. Oct. 13, 1953 [Oct. 13, 1952], No. 25638/52. Class 110 (2). The end faces of the gears of a gear pump are supplied with the same fluid as is pumped by the pump but at a pressure greater than the delivery pressure thereof in order to reduce the feakage of fluid over the said end faces. The highpressure fluid is fed through conduits 23, 22 and a valve 24 to annular chambers 21 which are bounded by the shafts 10b, the casing 10c and the gear-wheels 10a. The valve 24 comprises a tapered member 24b controlled by diaphragms 25, 26; the former being responsive to the pressure in the conduit 22 and the inlet pressure of the pump whilst the latter is responsive to the delivery and inlet pressures of the pump through conduits 29, 28, respectively. Spaces 19 at the end of each shaft are connected by bores 18 and a duct 20 to the inlet side 10d of the pump. The arrangement is such that the pressure in the chambers 21 is higher than the discharge pressure of the pump by an amount proportional to the pressure rise through the pump. However, the pressure in the chambers 21 may be maintained higher than the discharge pressure of the pump by constant amount or at a constant value substantially higher than the discharge pressure of the pump. In such an arrangement the conduits 22 may be directly connected to the conduit 23 with a spring- loaded relief valve disposed therebetween, see Fig. 3 (not shown). In a modification, the conduit 23 incorporates a valve controlled by a diaphragm responsive on one side to the pressure in the conduit and on the other side to the discharge pressure of the pump and a spring, the arrangement being such that an increase of pressure at the discharge side of the pump increases the opening of the valve. The gear pump described above may be incorporated in a speed-sensitive system, see Fig. 1 (not shown), wherein the pump recirculates liquid to a tank through a restricting orifice, the pressure drop across which is employed to give an indication of the speed at which the pump is driven.

Title: The synthesis of diamonds
IPC: B01J3/06
Filed: 1961-07-17
Abstract: <PICT:0950303/C1/1> Diamonds are synthesised from a saturated solution of carbon in a molten solvent, prepared by subjecting a mixture of carbon and solvent material to a required temperature and pressure.  In one procedure a mixture of graphite and nickel is subjected to increasing pressure up to B, not exceeding that at which the melting point line of the solvent, Q, intersects the diamond graphite equilibrium line P, and the temperature is then increased to the required value C above the melting point of the solvent. The pressure is then increased further to a required value, D, when growth of diamonds is initiated due to the crossing of the graphite-diamond equilibrium line in the direction graphite-diamond. Temperature and pressure are maintained constant at their required values for a period of time, the temperature is then decreased to atmospheric and the pressure is finally reduced to atmospheric.  In an alternative procedure the temperature is increased to J, beyond the required value, the pressure is increased to its required value, K, and the equilibrium line is again crossed in the direction graphite-diamond by subsequently decreasing the temperature to the required value D.  In Example 1,200 mg. C + 550 mg. Ni are treated and B is 42,000 atmos., C is 2100 DEG  C., D is 75,000 atmos. and the temperature and pressure are maintained constant for 5 minutes.
