Title: Improvements in or relating to engine starting mechanism
IPC: F02N15/06
Filed: 1945-10-12
Abstract: 602,120. Inertia starters. CLEVELAND, F..J. (Bendix Aviation Corporation). Oct. 12, 1945, No. 26721. [Class 7 (v)] An inertia starter, Fig. 1, whose flywheel 5 is connected to the engine engaging jaw member 8 through a reduction gear 16, 17 known torque limiting clutches housed in the casing 4 and a clutch 41 has its flywheel energized by an electric motor 6 through a free wheel device 29, 31, 33 and clutch 41 held in engagement by a spring 51, the said clutch being held from engagement with the flywheel, after it has been energized, by a solenoid 71, acting through a lever 55 to the thrust member 56, Fig. 2, when the jaw member 8 is engaged with the corresponding engine member 9. In operation the knob 80 is pulled, so closing the switch 78 and energizing the motor 6 and flywheel 5. Knob 80 is then pushed to break switch 78, engage members 8 and 9, close switch 79, energize the solenoid 71 so disengaging the flywheel 5 from clutch 41 and close clutch 14 so that the motor 6 remains in circuit and gives the engine an initial rotation. The contacts 83 of switch 79, Fig. 6, are then turned through 90 degrees so that the insulated portions 85, 86 of the switch break the circuit, the motor 6 and solenoid 71 are then de-energized and the clutch 41 engages the flywheel 5 which then expends its energy turning the engine. During this latter operation the armature of motor 6 is free to come to rest because of the free wheel unit 29, 31, 33. When the engine starts the controls are returned to the position shown in Fig. 2. Specification 304,275, [Class 7 (v)], and U.S.A. Specifications 2,038,191 and 2,156,602 are referred to.

Title: Improvements in or relating to aerial systems
IPC: H01Q21/12
Filed: 1928-09-18
Abstract: 299,447. Marconi's Wireless Telegraph Co., Ltd., (Assignees of Lindenblad, N. E.). Oct. 28, 1927, [Convention date]. Directive signalling.-In an " end on " aerial system built up of an array of radiators, such as 14, Fig. 1, the feed-lines 2 are of large crosssection, or comprise a number of conductors in parallel, and are closely spaced. The radiators 14 are coupled transversely, and external to the feeders through inductances 12. Other transverse inductances such as 16 are used to regulate the alternative characteristic and to control the rate of energy-flow in the feeders from a velocity equal to that of light for " end-on " directive transmission and energized by feeders 68, 70 from a source 74 through a distributor device 72 which feeds first one system and then the other alternately. The aerial arrays are inclined at different angles to the horizontal so that the effective radiation is " wobbled " in order to minimize fading. The transverse radiators may be horizontal, vertical, or intermediately inclined. Fig. 6 shows a triple " endon " aerial system energized by two-wire feeders 78, 100, 102 for focussing the directed beam. Adjustable "trombone" sliding connectors 112, 114, 116 are provided as shown, and may be controlled by pulleys and cords 134, 132, or levers 136, 138, in order to vary the effective length of the feeders and thereby the phase-relations of the different sectors of the array. This enables the transmitted beam to be focussed by regulating the convergence of the radiated waves, and also admits of " warping " the directivity of the system. In the Specification as open to inspection under Sect. 91 (3) (a) similar broadside aerial systems are also described. In one example a verticallytilted broadside aerial is backed by a similar reflecting array, both systems being directly energized and spaced apart by an odd number of quarter wave-lengths, say five. For broadside transmission generally the velocity of propagations along the feed lines is arranged to have an apparently infinite velocity. This subject-matter does not appear in the Specification as accepted.

Title: Fluid Temperature Logging While Drilling
Inventor: ARPS JAN JACOB
IPC: E21B47/06
Filed: 1967-06-12
Abstract: 1,170,487. Boring earth. ARPS CORP. 12 June, 1967, No. 27009/67. Heading E1F. [Also in Division G1] The temperature gradients in the region of a drill bit at the bottom of a bore hole are monitored to determine the drillability of each formation reached by the bit and the thermal conductivity of the formations which have already been drilled. As shown (Fig. 1), a well logging system comprises a drill bit 13 supported by pipes 15 and Kelly bar 16 for rotation by motor 30. Drilling fluid is supplied from a reservoir 40 by a pump 36, circulates through the centre bore of pipes 15 and drill bit 13 and comes up round the piping system to outlet 42. The bottom portion 52 of the drill. collar 14 carries four thermistors 60-63 (Fig. 3) located as shown the thermal energy produced by the drill bit 13 is determined by measuring the temperature rise in the drilling fluid as it flows through the drill sensed by thermistors 60, 61, and measured in a resistance bridge 65. The thermal conduction of the earth formations is determined by measuring the temperature of the drilling fluid at spaced locations as it flows up past the formations using thermistors 62, 63 connected into a second bridge 75. The outputs from the bridges are alternatively switched into a voltage to frequency converter 80, and fed to a fluid control valve 83 and to a relay 85 which controls the changeover switch 71 and produces distinctive marking on the two outputs from converter. 80, the relay 85 being operated after a pair of pulses derived from each bridge. Thus the time interval of each pulse pair is proportional to the specific temperature difference being measured. The pulses fed to the fluid control valve 83 produce pressure pulses which are sensed at the surface by a transducer 47, and the time intervals reconverted at 100 to voltage signals, which are combined at 101 with a fluid flow rate signal from generator 103 driven by pump 36, the product signals, representing drillability and thermal conductivity, being recorded separately at 50 against depth in the bore hole. Sudden change in the signals recorded at 50' may be used as alarm signals indicating special conditions at the boring location.
