Title: Improvements in the lubrication of internal combustion engines, compressors and the like
IPC: F16N13/14
Filed: 1930-08-01
Abstract: 360,461. Force-feed lubricating. PRESTWICH, J. A., 28, Canfield Gardens, Hampstead, London. Aug. 1, 1930, No. 23288. [Class 12 (iii).] Lubricating apparatus for an internal-combustion engine, compresser, or the like comprises three pumps associated together,. of which the first pump re-circulates direct to the moving parts oil draining into the crank case, while the second pump draws fresh oil from a tank and supplies measured quantities to the third pump which delivers it to the moving parts either alone or mixed wholly or partly with the delivery of partly-used oil from the first pump. A plunger d, Fig. 2, is fitted in a cylinder c in a casing a and a plunger d<1> of smaller diameter fitting in a bush c<3> in the cylinder has a pin-and-slot connection d<2>, d<3> with the plunger d and is pressed outwardly by a spring d<4>. Three pumping chambers f, f<1>, f<2> are thus provided. The plungers are rotated by worm gearing d<5>, e and caused to reciprocate by cams n, o coacting with abutments p, q. Fresh oil is drawn into the chamber f<1> from the tank through passages g<1>, g, and is discharged through a port g<2> and drip pipe h into a sight-feed chamber b. From the latter it is drawn into the chamber f<2> through a port and is discharged through a port j<1> to a passage k connected to the parts to be lubricated. Used oil is drawn from a well in the crank case into the chamber f through passages h<1>, l and is discharged through a port m to the passage k. The plungers have suitable ports co-operating with the ports in the cylinder and bush. The supply of fresh oil may be regulated by adjusting the screwed plug c<1>, which limits the throw of the plunger d<1>. The abutment q may be formed as a cylindrical abutment mounted eccentrically, so that by rotation thereof the throw of the plunger d may be regulated. In a modification, the plunger d<1>, Fig. 3, is integral with the plunger d and a cam groove n in the plunger d is engaged both by a fixed pin p, Fig. 9, and by an eccentric extension of a rotatable pin q. An excess of oil is drawn into the chamber f <1> on the suction stroke and oil is returned through the port g on the discharge stroke until that port is covered, when the pin p ceases to cause movement of the plunger, which remains stationary until the port g2 is uncovered, after which the pin q comes into action to complete the discharge stroke. By rotating the pin q, the supply of fresh oil may be regulated. ,

Title: Improvements in thyristor firing circuits
Inventor: WEAVER JOHN JAMES LAURENCE
IPC: H02M1/092
Filed: 1968-05-16
Abstract: 1,269,502. HVDC static converters. ENGLISH ELECTRIC CO. Ltd. 13 May, 1969 [16 May, 1968], No. 23305/68. Heading H2F. [Also in Division G1] In an HVDC converter groups of thyristors in a series chain, are fired simultaneously from a common pulse generator 14 the pulses from which are transmitted in the form of light waves (visible, infra-red or ultra-violet) through filamentary light guides 7, 9 to firing circuits local to the thyristors, the guides being coupled to a plane polarized light source through a polarized filter and the plane of polarization is controlled by the pulses from generator 14 such that light waves are transmitted through the filter only during a said pulse. Light waves in filaments 9 are converted to electrical signals by photo-transistors or photodiodes 10 to actuate pulse generators 11 which send firing pulses through distributing and gating circuits 13 to fire all the thyristors in groups 1 simultaneously. Alternatively there may be a respective pulse generator 11 and photo-sensor 10 for each thyristor. Light from a source 2 is directed through a polarizing filter 3, a solid crystal 4, and the polarizing filter 5. It is then focused by a lens 6 on to the end of a bundle of filamentary light guides 7. These guides enter a mixer or brancher 8 having output bundles of light guides 9. The crystal (e.g. of Yttrium iron garnet) when subjected to a magnetic field in response to a pulse from generator 14, rotates the plane of polarization of the plane polarized light through filter 3 to align with that at which the filter 5 imparts least attenuation so that the light wave impinges on the light guides 7 and the thyristors are fired. In the absence of an energizing field the plane polarized light through 3 passes through the crystal but is severely attenuated by filter 5 since this is polarized in a different plane and the thyristors will not be fired. Alternatively the crystal may be of ammonium dihydrogen phosphate disposed in an electrostatic field. The series strings of thyristors may be connected to form a bridge network.

Title: Improvements in and relating to concrete and compositions therefor
IPC: B01F7/00
Filed: 1932-10-20
Abstract: 412,556. Reinforced concrete. GAMMON, J. C., 8, Thornton Way, Hampstead, London, and MORGAN, J. S., Rodridge Hall, near Wingate, Co. Durham. Oct. 20, 1932, Nos. 23384, 33114, and 33115. Drawings to Specification. [Class 20 (iv).] A process for making fluent cement grout for concrete consists in first mixing cement, water, and fine mineral filler such as sand, chalk or granite dust, and then subjecting the mixture to intensive mixing between closely adjacent surfaces not in grinding contact but in rapid relative movement. The intensive mixing may be done by an ordinary colloid mill. The product is said to possess a high degree of fluidity and to be such that the filler does not readily separate from the cement ; it may be used for making concrete walls and beams by pouring it, preferably through vertical pipes which are raised as the filling proceeds, into the interstices of previously wetted coarse aggregate placed in position between shutters. The pipes may be perforated and may rest on U-shaped perforated channel members arranged horizontally in the wall or beam. The pipes may be of wire mesh or expanded metal and may be left behind in the concrete after grouting as reinforcement, being filled up with aggregate and grout. Specification 328,030, [Class 22], is referred to.

Title: Improvements relating to vehicle warning devices
Inventor: BOOTH RICHARD HERBERT
IPC: G08G1/16
Filed: 1960-07-05
Abstract: 987,214. Locating conductive and magnetic bodies. ELECTRIC & MUSICAL INDUSTRIES Ltd. June 30, 1961 [July 5, 1960], No. 23395/60. Heading G1N. [Also in Divisions G4 and H4] In a system for warning a vehicle of the presence of another vehicle ahead (or behind) in the same traffic lane 1-2, two signal paths are provided extending along the traffic lane in the form of transmission lines or, as shown, series of transformer coupled coils M r , M r+1  &c. N r , N r+1  &c. A transmitter on a vehicle injects a signal into the coil M r , M r+1  &c. over which it is located, the signal travelling along the M signal path until it reaches another vehicle in the lane which couples the two paths. The signal is thereby returned along the N path to a receiver on the first vehicle and actuates an indicator. In the direction of traffic flow 3 there is a voltage step up between successive M coils and a voltage step down between successive N coils, thus discriminating between signals from a vehicle ahead and from a vehicle behind. However by reversing these step-up and down arrangements following vehicles may be detected in lieu of vehicles ahead. By choosing appropriate transformation ratios of the coil coupling transformers the amplitude of a received signal may be proportional to the distance between the two vehicles. To cancel the signal produced in a vehicle receiver due to the path coupling effected by the vehicle itself a bucking signal may be provided. Preferably, however, a 30 degreees phase shift is produced between successive coils in the signal paths and the receiver is made phase sensitive thereby also to indicate the distance between the vehicles in question. The M and N sets of coils are arranged at right angles to each other to prevent direct coupling between them. The N coils may be in the road surface and the M coils beside the road so that adjustments between them may be made. When transmission lines are used in lieu of the coils a directional coupler effect can be obtained to discriminate against a following vehicle.
