Title: Improvements relating to sections for constructing railway sleepers
IPC: E01B3/36
Filed: 1961-01-04
Abstract: 916,192. Railway sleepers. KRUGER, C. J., and SOUTH AFRICAN IRON & STEEL INDUSTRIAL CORPORATION Ltd. Jan. 4, 1961 [Jan. 4, 1960], No. 427/61. Class 104 (2). In a railway sleeper consisting of two concrete blocks 1, 2 interconnected by a rolled steel crosstie 6, the cross-tie 6 is of an inverted U-shaped cross-section and has enlarged area concentrations in or on either side of the apex and at or near the extremities of the U-shaped crosssection. An example of the cross-tie sectional shape is shown in Fig. 2 and consists of a dome top portion 7 reinforced on its underside by material concentrations 10 arranged to form a groove 11 to receive the T-head, to prevent rotation, of a rail-securing bolt 5. The webs 8 diverge downwardly and terminate in material concentrations in the form of beads 9 or outwardly turned flanges, Fig. 5 (not shown). In the arrangement shown in Fig. 7, the T-heads 15 of the bolts 5 are inserted in a slot, both in the concrete block 1 and the cross-tie 6, arranged transversely to the longitudinal axis of the cross-tie 6 and are then turned through 90 degrees and lifted to engage the T head with the groove 11 in the cross-tie 6. In this arrangement the underside of the T head 15 is tapered and the securing bolt receiving holes in the concrete block 1 are tapered as at 17 to permit the bolts 5 to move from the vertical. The end of the cross-tie 6 may be bent outwardly at 8a to secure the crosstie 6 in the concrete block 1. In alternative arrangements the securing bolts may be welded to the cross-tie 6 or connected to nuts fixed or placed inside the cross-tie 6. In a further arrangement, Fig. 9 (not shown), the T head of the securing bolt 5 is inserted in a Z-shaped slot arranged along the longitudinal axis of the crosstie 6 and the bolt is turned through 90 degrees and lifted and then held in this position by its end faces engaging the walls in a wide slot 11 and by its side faces abutting the walls of suitably shaped apertures, Fig. 8 (not shown), provided in the concrete blocks. The above apertures serve to drain moisture from the blocks or alternatively, Figs. 1 and 7, draining apertures 30 may be provided. In a further embodiment in which the rails are held down by screws engaging wooden plugs embedded in the concrete blocks 1, 2 or by bolts passing through the blocks the ends of the cross-tie 6 embedded in the blocks 1 and 2 are bent to an S shape in the horizontal plane to avoid such wooden plugs or bolts, Fig. 11 (not shown).

Title: Improvements in radiating antenna systems
IPC: H01Q21/12
Filed: 1926-01-07
Abstract: 246,816. British Thomson-Houston Co., Ltd., (Assignees of Kellogg, E. W.). Jan. 30, 1925, [Convention date]. Artificial lines and balancing-network.-In an array of aerials for directive transmission the oscillatory current is supplied to all the aerials by a single line which is so designed that the power consumed by each aerial is substantially the same and that the waves in the supply line do not suffer reflection at the points where the aerials are connected. By an application of the theory which has been developed in connection with wave filters it is shown that if the aerial A, Fig. 1, is to have an effective resistance of 1000 ohms and to radiate 1000 watts, and if the aerials B and C radiating the same power be connected in shunt, through series resistances b, c, as shown, no reflections will take place provided that the circuits be dimensioned as indicated in the drawing. Instead of T-sections, suitably dimensioned L- sections may be employed. In practice, provided the effective impedances of the sytem be substantially ohmic, the arrangement shown in Fig. 3 may be employed, where. the intermediate aerials 4 - - 7 are coupled to both shunt and series resistances.

Abstract: 488,566. Valve circuits for wireless reception. RADIOAKT.-GES. D. S. LOEWE. Jan. 8, 1937, No. 625. Convention date, Jan. 13, 1936. Addition to 458,147 and 458,149. [Class 40 (v)] In a superheterodyne receiver in which radiation is prevented as described in the parent Specifications by feeding potential of opposite phase to the grid of the potential applied from the oscillator through inter-electrode capacities a second bridge circuit is provided one diagonal of which is connected between the cathode of the frequency changer and earth while the other diagonal is connected across the tuned circuit of the local oscillator. Fig. 1 shows a frequency changer in which the circuit of the local oscillator is tuned by the condenser 7a, 7b whose junction is connected to the cathode. Radiation due to coupling 13 is neutralized by condenser 12. A resistance 24 may be connected in series with the grid, or alternatively a resistance may be provided in parallel with condenser 7b to ensure exact phase opposition, or the oscillator may be a tetrode or pentode having a large anode impedance. The second bridge circuit is constituted by condensers 7a, 7b and differential condenser 17, 18, 19 which has a capacity equal to the capacity 10 between the grid 3 and the cathode. Fig. 3 shows an arrangement in which the balancing condenser 12 is dispensed with and the cathode is arranged to be in opposite phase to the oscillator grid by adjustment of the differential condenser.

Title: Improvements relating to vacuum brake apparatus for railway and like vehicles
IPC: B60T13/46
Filed: 1949-01-10
Abstract: 660,831. Vacuum brakes. GRESHAM & CRAVEN, Ltd., and MARSH, G. C. Jan. 9, 1950 [Jan. 10, 1949], No. 663/49. Class 103 (i). [Also in Group XXVIII] Automatic control of the steam supply to an ejector g drawing air from a vehicle brake system through an automatic feed valve c which remains open below a vacuum less than twenty inches of mercury and closes for a vacuum of or above twenty inches mercury gauge in the system is effected by a governor valve i acting to prevent or allow the passage of steam to the ejector according to whether the vacuum in a reservoir d is about 25 inches or below 20 inches mercury gauge. The valve i is opened against a spring r by reservoir vacuum acting above a diaphragm v to allow access of vacuum through a pipe w to the underside of a diaphragm x to close a valve j in the steam supply line. On reduction of vacuum in the reservoir d the valve i closes, and a vent u is opened allowing access of atmospheric air below the diaphragm x to open the valve j. The automatic feed valve c is opened by the pressure of a spring n and is closed by differential pressure across a diaphragm o ; the pressure at the upper side being that of the train pipe a except during a brake application when the valve c is isolated from the pipe a by the driver's valve b, and the pressure at the lower side being atmospheric except in the full release position of the valve b when it is equal to the train pipe pressure thereby putting the diaphragm o in equilibrium. In a modification a hand-controlled supplementary ejector draws between the valves c and b to exhaust the brake system when desired.

Title: Improvements in or relating to the treatment or purification of pressed, starchy pectin-containing materials
IPC: C08B37/00
Filed: 1937-07-11
Abstract: Pressed starch- and pectin-containing materials, e.g. apple or pear pomace from which the juice has been removed by pressing, are heated with water to about 140-200 DEG  F., and diastatic enzyme is subsequently added to solubilize the starch in the pulp which may then be dried for storage.  In an example, fresh apple pomace is ground to a fine pulp and five or six times its weight of water is added.  The material is next agitated in a tank and the temperature raised to and held for one minute at 177 DEG  F., and the material cooled to about 90 DEG  F., or else the liquid is drained off and replaced by cold water to adjust the temperature to 90 DEG  F. Sufficient diastatic enzyme preparation is next added to hydrolize the starch in 15-20 mins.  The liquid is finally pressed out and the residue dried.  The material may be bathed with alcohol to facilitate drying.  Pectin may be obtained from the dried material, e.g. by boiling for about 10 mins. with water acidified to pH 2,5.ALSO:Pressed starch- and pectin-containing materials, e.g. apple or pear pomace from which the juice has been removed by pressing, are heated with water to about 140-200 DEG  F. and diastatic enzyme is subsequently added to solubilize the starch in the resultant pulp which may then be dried for storage.

Title: Vehicle brakes
IPC: F16D65/56
Filed: 1973-01-05
Abstract: 1458361 Disc brakes; brake elements; transmitting mechanisms; wear adjustment GIRLING Ltd 20 Dec 1973 [5 Jan 1973] 852/73 Heading F2E A vehicle disc brake comprises a plurality of elongated friction members 2 having ends engageable with a rotor 7 and being supported in slots 3 in a casing 1, the friction members 2 2 being applied to the rotor 7 by an actuating mechanism including a beam 9 screwed to an adjuster screw 10 extending through the casing 1 alongside the friction members 2. In the illustrated embodiment the rotor 7 is a railway vehicle wheel and the casing 1 extends substantially the full length of an axle, terminating close to the inner surfaces of wheels 7 which act as braking surfaces for co-operation with respective sets of friction members 2. The casing 1, which may be in axial sections, is supported against drag forces but has a degree of "end" float to accommodate wheel set end float. The members 1 project through apertures 6 in the casing 2, and during braking drag forces are transmitted to side edges 5 of the apertures 6. The inner end of each member 2 is supported by a metal cap 8, preferably having a prestressed resilient means, such as a pair of belleville washers (11) through which braking forces are transmitted by the beam 9 which acts on all the caps 8-this serves to equalize the forces. The beam 9 which is keyed against rotation in slots 3 is movable via screw 10 by actuation of a wedge expander 12 located at the mid-point of casing 1-the screw 10 is journalled in a blind bore in the adjacent end of a roller-tappet of the expander 12. The screw 10 extends outwardly through a protective guide tube 19 which may be of friction or other expandible material to be worn away as members 2 wear. To adjust for wear the actuator wedge carries a pawl 13 co-operable with a ratchet wheel 14 mounted on a spindle 15, the outer ends of which have pinions meshing with gear-wheels 18 carried by the respective adjuster screws 10- the pawl 13 becomes effective to rotate the wheel 14 on an actuating stroke of the wedge exceeding distance X. Suitable provision is made to protect the adjuster components against excessive operating loads, e.g. resilient means for storing energy to effect adjustment on the return stroke or a frictional clutch means which slips under excessive loads. As shown, each member 2 is arranged to engage the whole swept area of the braking surface. If desired a larger number of friction members may be employed some of which engage an inner annular zone of the swept area, while the rest engage an annular outer zone.

IPC: F02N15/10
Filed: 1927-01-12
Abstract: 282,991. Bennett, A. Jan. 12, 1927. Turning-gear.-In mechanism for preventing the starting-handle of a motor vehicle from being engaged with the engine shaft unless the gearlever B of the vehicle is in the neutral position, a. blocking device D for preventing the movement of the starting-handle is prevented from being moved when the gear lever is not in the neutral position by a slide or plate A which is engaged by the gear lever and prevents movement of a lever, rod, or bar C<1> affixed to the blocking device. In one form, Fig. 1, a shaft C<1> rocking in bearings c<1>, c<2> carries at one end an arm D adapted to pass behind a collar e<1> on the shaft of the starting handle E, and at the other end a forked lever C carrying a pin c. The plate A is pivoted at a and has a slot a<1> engaged by the gear lever B and a hole a<2> into which the pin c can only enter when the gear lever is in the neutral position, when the shaft C<1> can be rocked to move the arm D out of the path of the starting-handle. In order that backward movement of the starting- handle may be prevented if the engine shaft turns backwards at starting, the collar e<1> may have ratchet teeth, the arm D acting as a pawl. In order that the axial movement of the starting- handle may move the arm D aside, the collar e may have a conical part e<2>, Fig. 8, and the collar may also have ratchet or other teeth e<3> for preventing rotation of the starting-handle if it should be possible to force the end of the arm D up the cone when the gear lever was' not in the neutral position. In a modification, Fig. 11, the gear lever B actuates a plate. A sliding in guides b, and a lever C<1> is pivoted at c' and carries at its ends a pin c for engagement with a hole a<2> in the plate A and a forked member D<1> in the path of the starting-handle, a spring s tending to hold the lever in the position shown. An inclined face d on the member D' enables the member to be pushed aside by the movement of the starting-handle when the gear lever is in neutral position. In a further form, a cranked rod is supported by parallel-motion links and has at one end a. pin for engagement with a hole in a plate such as A and at the other end a forked member such as D'.
Patent HK-54786-A (HK)
Title: Centrifugal separator
Inventor: MARTIN HENRY WOODS
IPC: F01M1/10
Filed: 1986-07-24
Abstract: A centrifugal separator for separating contaminants from contaminated oil has an outer casing (10, 11) and a rotor (20) within that casing mounted for rotation about a vertical axis. Oil under pressure enters the rotor at one end and at the other end exits through jets (78) into a chamber within the casing which is normally filled with air. As the jets of oil impinge upon the inner wall of the casing, a small amount of air becomes entrained in the oil and as the oil flows to a sump, the air is gradually removed from the interior of the casing. In order to prevent a build-up of oil within the casing, which could interfere with rotation of the rotor (20), air under pressure is supplied to the interior of the casing by means of a float-operated valve member (113) so that while the valve member is normally closed, any increase in the oil level will cause the float (124) to rise with that oil level and thereby open the valve (113) to allow additional air to enter into the interior of the casing.
