Title: Process for the production of hollow bodies by centrifugal casting and apparatus for carrying out the process
IPC: B22D13/10
Filed: 1934-04-10
Abstract: 428,157. Casting metals &c. DEUTSCHE EISENWERKE AKT.-GES., Mulheim-on- Ruhr, Germany. April 10, 1934, No. 10819. Convention date, Jan. 18. [Class 83 (i)] [See also Group V] Metal and other hollow bodies such as asbestos cement tubes are cast centrifugally with the aid of a distributer movable axially with respect to a rotating mould having an horizontal axis, the velocity of the material being cast being reduced on its way to the outlet end of the distributer to cause the material which flows out of the distributer in a wide stream, to pass into the mould merely under the tractive action of the inner wall of the mould without eddying or the formation of waves. The material flowing along the narrow portion 1 of a distributer loses speed in the widening portion 2 as it approaches the outlet 3 across which it passes as a broad shallow stream. The edge of the distributer may be perpendicular or oblique to the mould axis, be straight, convex or concave, and have an undulating form transverse to the direction of flow or be provided with projections or notches. The distributer may have a longitudinal partition to permit simultaneous casting of two materials, the first to strike the mould forming a heat-insulating coating and increasing the resistance of the finished tube to corrosion.

IPC: D06B1/00
Filed: 1923-04-21
Abstract: 219,380. Sellers, A. E. April 21, 1923. Rotary apparatus.-The angle at which the spray is thrown off by a rotary spraying-brush 20 is varied by mounting the brush in such a manner that it can be adjusted circumferentially with respect to the feeder-brush 11 which dips into a trough 9 of liquid; and the density of the spray is varied by adjusting the depth of penetration of the two brushes or by varying their relative speeds. Thus, the brush 20 is mounted in bearings 30 carried by arms 17 capable of being rocked about the axis of the feeder-brush 11, or by worm gear 16<1>, 22, 27; and the bearings of the spraying-brush 20 can be adjusted radially by mounting them as nuts on screwed rods carried by the arms 17 and actuated by a common hand wheel 21'. The brushes rotate in the same direction, but the speed of the spraying-brush is greater than that of the feeder-brush; and since the latter is driven, intermediate gears 29 carried by links 31, 32 are interposed in the drive in order that the necessary relative adjustment of the position of the shafts may be obtained. The brushes are preferably built up of discs secured to their respective shafts; and the bristles of the spraying-brush are preferably not so densely set as those of the feeder-brush.

Title: Improvements relating to track brake devices
IPC: B60T13/66
Filed: 1928-04-19
Abstract: 297,448. Westinghouse Brake & Saxby Signal Co., Ltd., (Assignees of Down, S. G.). Sept. 22, 1927, [Convention date]. Electric and magnetic; fluid-pressure ; skid.- Electromagnetic track brake shoes for railway vehicles are arranged to be moved into contact with the rail by means, such as fluid-pressure, other than the magnetic attraction between the shoe and the rail and to be subsequently and automatically energized, to avoid the necessity of supplying a high initial current for this purpose. The shoe 1 is carried by a piston 5 in a cylinder 6 to which pressure fluid is supplied by pipes 12, 17 past a spring pressed piston valve 10 which in its normally seated position connects the cylinder 6 to an exhaust port 15 by way of a passage 19. The circuit of the magnetizing coils of the shoe 1 includes contacts 26, 27 adapted to be connected by a contact 25 carried by a piston 21 the cylinder 20 of which is connected to the cylinder 6. The pipe 12 is connected to the straight air pipe of the fluid pressure braking system or to the usual brake cylinder. When pressure fluid is thus supplied to the pipe 12 the piston 10 is moved upwardly when the pressure reaches a predetermined value to close the exhaust passage 19 and permit the passage of the fluid to the cylinder 6 and the switch cylinder 20. The piston 5 is first moved to bring the shoe 1 into contact with the rail and consequent upon the further rise of pressure the piston 21 is moved to close the contacts 25, 26, 27 and energize the shoe. When the pressure fluid is released from the pipe 12 the piston 21 is first moved to break the circuit and the piston 5 then withdraws the shoe. When the fluid pressure falls to a predetermined valve the piston 10 re-seats and the pressure fluid remaining in the pipe 17 is vented through the passage 19. The pistons 10, 21 seat upon circular ribs 11, 22 so that only a restricted area is exposed to the fluid pressure until the pistons are unseated, a rapid movement of the pistons being thus ensured.

Title: Improvements in or relating to a synchromesh device for change-speed gears
IPC: F16D23/02
Filed: 1963-03-22
Abstract: 1,033,503. Positive clutches. BAYERISCHE MOTOREN WERKE A.G. March 22, 1963 [March 23, 1962], No. 11558/63. Heading F2C. In a split-ring synchronizer for dog clutches 5, 7; 6, 7 of a motor-vehicle change-speed gear wherein the expanding action of the split ring 8 is servo-assisted by a wedging member 11, the latter acts on the trailing end 8<SP>1</SP> of the split-ring 8, thereby avoiding premature self-locking produced in prior arrangements which wedge on the leading end. On initial engagement, friction drag in the synchronizing ring 8 by the clutch teeth in the direction of rotation D, Fig. 3, causes the trailing end 8<SP>1</SP> of the ring to tilt the wedge member 11 about a fulcrum formed by a recess 13 in the clutch hub 3<SP>1</SP>, whereby an arm 17 of the wedge member acts radially outwards on the trailing edge 8<SP>1</SP> of the ring 8 to provide the servo assistance. At the same time the trailing edge 8<SP>1</SP> of the ring acts to slide a latch member 12 along an arcuate surface 12<SP>1</SP> in the wedge member 11 so that a surface 21<SP>1</SP> on the latch member supports radially the leading edge 811 of the ring 8. With the ring 8 thus expanded, positive clutch engagement is balked until attainment of synchronism cancels the reaction forces and permits the dog clutch to pass over the ring into positive engagement. To facilitate engagement of the starting gear from standstill, the latch is formed in Figs. 5 and 6 (not shown) with one side of its lug set back flush with the lug of the locking member in their normal unengaged central position, thus excluding the action of the latching member for the direction of rotation corresponding to the engagement of the starting gear. Additionally, in Fig. 7 (not shown), the arm of the locking member which moves into engagement with the trailing edge of the synchronizing ring, under these conditions, is made substantially longer, thereby exerting a smaller supporting force on the ring to further facilitate engagement of the starting gear.

Title: Improvements relating to apparatus for determining the fullness of railway classification tracks
Inventor: GROSE BASIL HUBERT
IPC: B61L17/00
Filed: 1959-04-04
Abstract: 930,644. Railway classification tracks. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. March 17, 1960 [April 6, 1959; July 10, 959], Nos. 11562/59 and 23739/59. Class 105. The fullness of a railway classification track is determined by producing a signal indicative of the distance between the entrance to the track and a vehicle thereon nearest to the entrance and determining the rate of change with respect to time of that signal to determine whether the nearest vehicle is stationary or moving and if moving the application of the signal to a utilization device is rendered ineffective. The classification track ABCD is formed into a track circuit by insulated joints and the circuit fed at A, B with a constant amplitude voltage from the source 2 at 500-2000 c/s. The voltage at AB depends upon the distance of a vehicle from the point AB and is applied to a detector 3 whose D.C. output is applied to a voltage-time differentiating device 4 which feeds into a movement indicating relay IR which thus operates if the vehicle is moving resulting in an output from device 4 and contact IR1 opens in the operating circuit of the motor 6 of a positionanalogue device 7 which thus cannot operate until the vehicle becomes stationary. The voltage output from detector 3 is applied also to a voltage differencing 5 to which also a voltage from device 7 corresponding to the position of the previous vehicle entering the track, is applied and the difference voltage output applied to control the motor 6. Contact XTR1 in this control circuit opens when a relay XTR responsive to the presence of a vehicle in the approach section XT operates so that the position analogue 7 cannot be operated. A voltage from XTR2 may be applied through circuit represented by the broken line, to differentiating device 4 to provide an output to operate relay IR and indicate the presence of a moving vehicle in the approach section XT. In an alternative arrangement the output from a voltage-time differentiating circuit to which the track signal is applied, is fed to an indicating relay which if operated closes a circuit to light a lamp to indicate that the reading on a meter indicative of the fullness of the siding is invalid.
