Title: Improvements in or relating to elastometers
IPC: G01N11/16
Filed: 1958-10-13
Abstract: 844,204. Testing physical qualities of materials. BATAAFSCHE PETROLEUM MAATSCHAPPIJ N.V., DE. Oct. 13, 1958 [March 19, 1958], No. 32583/58. Class 106 (2). [Also in Group XXXVIII] Apparatus for determining the elastic properties of a bitumen comprises a horizontal beam with a vertical pivot resting in a conical hole filled with the bitumen, one end of the beam being made to oscillate, and the relative phase and amplitude of the oscillations compared with the driving force are measured and translated into an indication of the bitumen elasticity. As shown (Fig. 2) a beam 11 has a central vertical shaft 12 resting in conical bearings, the lower recess 17 being filled with bitumen whose temperature may be raised by a heating coil 20 to ensure adhesion between the bitumen and the surfaces of the shaft 12 and the recess 17. At one end of the beam is a permanent magnet 13 (Fig. 1), located between two coils 22 fed with A.C. from an oscillator 23, making the beam oscillate in its horizontal plane. The other end of the beam carries a plate 30 co-operating with fixed plates 31, 32, and an inductor 34 whereby the resonant frequency of the circuit varies as the beam oscillates. Coil 34 is coupled to an oscillator valve 41, and the L.F. signal across the grid resistor 42 has its phase and magnitude determined by the swinging beam. The magnitude is indicated by a volt meter 45, and the phase by a cathode-ray oscilloscope 62, or by a phase comparator circuit 50, and it is shown mathematically that the elasticity of the bitumen can be determined from these figures obtained for two values of moment of inertia of the beam 11, by adding weights 19 to the beam, and measured separately.

Title: Manufacture of graphitic material
Inventor: GREAVES CHARLES DESMOND
IPC: H01B1/04
Filed: 1947-12-12
Abstract: Graphite material for dynamo brushes is made by mixing at an elevated temperature, e.g. 100 DEG  C., natural or artificial graphite, preferably of coarse particle size say - 16+32 B.S.S., and pitch in the presence of a volatilizable hydrocarbon solvent such as solvent naphtha, moulding the mixture to shape, preferably by extrusion, and heating the moulded shape in air to a temperature about 200 DEG  C. which is sufficiently high to remove the volatilizable solvent but not so high as to cause appreciable decomposition or volatilization of the pitch.  A minor proportion of sulphur or of an oxidizing agent such as benzoyl peroxide, or selenium dioxide, and a proportion of finely comminuted bituminous coal may be added.  Prior to use the pitch may be purified, e.g. by distillation, and the graphite may be treated to ensure minimum ash content.  Specification 353,493 is referred to.

Title: Vehicle with retarding system

Filed: 1973-07-13
Abstract: 1440102 Motor vehicle brakes CATERPILLAR TRACTOR CO 13 July 1973 [19 July 1972] 33574/73 Heading B7M [Also in Division F2] A vehicular drive train with a prime mover or engine 11 coupled with an input shaft 12 for a gear ratio transmission 13 and a power output (e.g. a bevel gear assembly 14) coupled to the vehicle driven wheels, incorporates a fluid retarder 16 having a rotor 18 coupled to the input shaft 12; the retarder 16 is operable to brake the drive train by communication to the retarder 16 of fluid under pressure from a pump 27 such communication being brought about by operation of a valve 23 by means of a solenoid pilot valve 34 under the control of a speed sensing switch 24 associated with a rotating part of the drive train such as the input shaft 12. In the unactuated condition of the valve 23 shown in Fig. 1, the pump 27 which is driven from the engine 11 draws fluid from a sump, for example, in the housing 15 of the bevel gear assembly 14 and directs it to the valve 23. A spring-centred spool 33 of the valve 23 has the position where the fluid flows through the valve 23 and via a conduit 22, a heat exchanger 41, a branch conduit 21a, a conduit 21, the valve 23 again and a conduit 43 back to the sump. Fluid flow through the retarder 16 is limited. If the speed of the input shaft 12 goes above a predetermined speed (say 2200 r.p.m.) the switch 24 opens the pilot valve 34 and connects a conduit 36 from the transmission 13 to the spool 33 to move it against its spring (Fig. 2). The pump 27 is then communicated with the conduit 21 via a passage 39 while the conduit 22 is blocked, and fluid from the pump 27 flows through the retarder 16 and then through the heat exchanger 41 and a relief valve 42 to be returned to the sump. The drive train is therefore automatically retarded. A signal lamp 26 is provided to warn the driver when the absorption capacity of the retarder 16 is exceeded (e.g. when the input shaft rotates above 2400 r.p.m.).
