Title: Improvements relating to fluid pressure braking apparatus
IPC: B60T13/46
Filed: 1927-06-20
Abstract: 297,401. Le Clair, L. J., Brackenbury, A. G., and Westing-house Brake & Saxby Signal Co., Ltd. June 20, 1927. Fluid-pressure.-A release, accelerating or other controlling valve device for fluid-pressure braking-apparat.us is provided in the body of the valve device in a conduit leading from the train pipe to the brake cylinder with a non-return valve having an aperture therein, or a byepassage around the valve in order to restrict the flow of fluid to the brake cylinder, but allow free flow from the brake cylinder. The invention is shown applied to vacuum brakes but may be applied to fluid-pressure distributing, accelerating, &c. valves. In an accelerating valve for a vacuum brake, Fig. 3, the non-return valve comprises a pivoted flap 36, having an aperture 37, in the passage 35 leading to the brake cylinder. The accelerating poppet valve 27 is normally maintained closed by a spring 38. Increase of pressure in the train pipe 29 causes it to rise and admit air from the pipe 30 as the vacuum in a chamber 33 above a diaphragm 34 controlling the valve cannot be sufficiently quickly destroyed through the restricted aperture 32 through the valve. This valve device may be arranged in the branch pipe from the train pipe to the brake cylinder. The invention is also shown applied to a release valve and the non return valve comprises a poppet valve adapted to close grooves in the wall of the passage in which it is arranged when fluid flows from the train pipe to the brake cylinder, restricted flow of fluid being allowed through an aperture in the valve or a by-passage around it.

Title: Method of making steel and apparatus for charging steel making furnaces
IPC: F27D3/12
Filed: 1959-05-13
Abstract: 886,514. Charging steel-making furnaces. CALDERON AUTOMATION Inc. May 13, 1959 [May 23, 1958], No. 16343/59. Class 51 (2). [Also in Group XXX] Apparatus for charging an open hearth steelmaking furnace 1 comprises a charging car 5 carrying bulk supplies of scrap, ore and limestone and running on rails 3, 4, and a carriage 8 running parallel to the car 5 on rails 6, 7 and having thereupon a conventional ram-charging machine 66 and a rotary jib crane 65 respectively running on transverse rails 96, 97 and 94, 95. The charging car 5 has an end hopper 11 with inclined guide members 38 and 39 given a conical and oppositely directed configuration and respectively combined with triangular flat surfaces 45 and 46, said guide members acting as orienting surfaces deflecting lengthy pieces of scrap longitudinally through the gap 40 into a charging box 36 disposed below. Charging car 5 also has a large hopper 10 loaded with scrap. Charging machine 66 is used in the manner described below to charge the furnace using the single box 36. In a modification, Fig. 12 (not shown), the inclined surfaces 38, 39 are flap doors pivoted about their longitudinal edges and opened by a system of co-acting levers. The rotary jib crane 65 (see Group XXX) is arranged so that, as the crane moves forwardly, the boom 132 swings through an arc guided by a roller 131 in a cam guide 103. This results in the electromagnet 139 describing a straight line path over the hopper 10 to the hopper 11. The drive 112 for the carriage 104 and the drive 145 for jib slewing incorporate fluid couplings to allow for relative variations arising from the straight line path of the electromagnet. Upward movement of the electromagnet is controlled by a limit switch 140 on the end of the boom and downward movement by a relay on the drive control which functions when the electromagnet rests on the scrap. In operation, two charging cars are located in front of the furnace, the first having limestone in hopper 11 and scrap in hopper 10 and the second having ore in hopper 11 and scrap in hopper 10. Successive loads of limestone are dumped into charging box 36 and then transferred to the furnace until the first hopper 11 is empty, whereupon successive loads of scrap are also dumped by the jib crane over the partly-opened orienting doors 38, 39 into said box until the first hopper 10 is empty. The process is then repeated with ore and scrap from the second charging car. The orienting hopper 11 is shown mounted singly on a carriage for movement over a train of wagons carrying charging boxes, Figs. 9-11 (not shown).

Title: Improvements relating to branning and dusting machines for use in the manufacture ofmetal plates
IPC: C23C2/22
Filed: 1928-06-05
Abstract: 315,958. Thomas & Clement, Ltd., and Powell, R. June 5, 1928. Cleaning.-In a branning or dusting machine the cleaning material is brought into contact with the plates fed by rollers 2, 3 into a space 8 containing the material by a series of agitating members comprising propellers 11 having three blades 13 spaced at approximately 120‹ and secured on spindles 10 mounted in bearings on the bottom plate of the machine. The plates are guided through the space 8 by guides comprising inclined bars 20 and a central bar 21 mounted on a bar 17 having turned-up ends 18 secured to the side frames of the machine and a bar 22 secured to the bottom plate 9. The plates are guided between brushes 4, 5 by plates 23, 24 provided with inclined edges 25, 26 and then between rollers 6, 7 by which the plates are passed between dusting rollers 29-30. The propellers 11 may be arranged on both sides of the plates so that both sides are cleaned, and the blades 13 may be covered with soft felt, sheep skin, cotton &c. A plate 50 prevents the cleaning material in the space 8 touching the roller 2. In a modification, the guides comprise a number of spaced bars which are hooped or curved below or above the edges of the propellers 11.

Title: Record reader
IPC: G06K13/00
Filed: 1962-05-01
Abstract: 1,003,581. Statistical apparatus. S.C.M CORPORATION. May 1, 1962 [June 20, 1961], No. 16588/62. Heading G4M. Record guides 56, 60, Fig. 1, are manually positionable on table 52 so that the reader can accommodate 5, 6, 7 or 8-channel perforated tape or edge-punched cards. An adjustable guide 102 and a stop 98 are provided for cards, the cards being inserted by hand. The record is advanced through the sensing station stepby-step under the control of pulses from an external source, or is driven manually. The record travels under a fixed plate 62, being urged against the plate by a resiliently mounted friction pad. The record also passes under a transparent plate 64 which is hinged so that it can be raised for inserting a card. The plate 64 is mechanically coupled to stop 98 so that the latter is raised for engagement with the leading edge of a card only when plate 64 is raised. Plate 64 is also coupled to a mirror which is thus positioned to reflect light on to a row of photoresistive cells for sensing the record, only when plate 64 is lowered. Knob 88 is axially movable so that when pushed in the shaft of the knob causes the two halves of a clutch 166, 168, Fig. 9, to be engaged for manually feeding a card by turning knob 88. When the knob is pulled out, the power drive clutch 186, 188 is engaged. Shaft 274 is driven intermittently by a motor through a friction clutch and an escapement mechanism, Fig. 11. The teeth on wheel 326 are circumferentially offset from those on wheel 328, and the wheels are engageable by pawl arms 334, 332 respectively. Solenoid 342 is normally de-energized and arm 334 is in engagement with a tooth on wheel 326. On supplying a pulse to solenoid 342, arm 334 is disengaged and arm 332 is rocked into the path of the next tooth on wheel 328, but as the solenoid is normally de-energized again before arm 332 engages this tooth, shaft 274 is rotated by one complete step. If the pulse is longer than it should be, shaft 274 is stopped in the middle of a step by the engagement of arm 332 with wheel 328, and the step is only completed when the solenoid is again de-energized. In this way it is ensured that shaft 274, which drives sprocketwheels 68, 70, Fig. 1, only advances the record by one column at a time. A switch 248, Fig. 9, is actuated to indicate whether power or manual feed has been selected. Levers which project above plate 52 in sprocket-wheel apertures 72, Fig. 1, are used to actuate a switch to indicate when a part of the record is in the sensing station. Identical apparatus is described in Specification 1,003,582.
Patent GB-1501127-A (GB)
Title: False alarm inhibitor
IPC: G08B13/16
Filed: 1975-04-22
Abstract: 1501127 Intruder alarms CADIN ELECTRONICS PTY Ltd 22 April 1975 [23 April 1974] 16654/75 Heading G4N An intruder detector comprises a Doppler detection device including a transmitter 10, a receiver 11, quadrature mixers 12, 13 for multiplying a reference signal and the output signal of the receiver to discern between positive and negative Doppler shifts, an integrator 22 for integrating the output of the detection device, an alarm 24 adapted to be activated when the output of the integrator reaches a predetermined threshold level, and a false alarm inhibitor 25 which includes means activated when the output from the integrator reaches a predetermined level lower than said predetermined threshold level for phase-shifting by 90 degrees the difference in phase of the receiver output signal with respect to the reference signal. As shown in Fig. 1, the inhibitor 25 comprises a level detector 26 connected directly to a switch 27 and via an inverter 29 to a switch 28, the switch 27 being connected between a +45 degree phase shift network 30 and a buffer amplifier 32, and the switch 28 being connected between a - 45 degree phase shift network 31 and the amplifier 32, the networks 30, 31 being supplied from the oscillator of the transmitter 10 and the buffer amplifier 32 supplying the reference signal to the Œ45 degree phase shift networks of the mixers 12, 13. Thus, in operation, one of the switches 27, 28 is normally closed and the other normally open, but when the level of detector 26 is exceeded, e.g. Œ0À5 volts, the switches change over thereby phase shifting by 90 degrees the reference signal with respect to the received signal. Thus the directional sense of the integrator output due to the interfering source is reversed and will fluctuate about the level of detector 26 until removed. However, upon deflecting a genuine movement, the frequency of the received signal changes and the output of integrator 22 is not affected by the phase switch. A circuit arrangement of inhibitor 25 is described with reference to Fig. 2 (not shown).  The inhibitor 25<SP>1</SP> shown in Fig. 3 comprises a divide-by-4 circuit 40 arranged in a phaselocked loop with a phase-detector 41, a filter 42 and a voltage controlled oscillator 43 that provides an output signal at four times the frequency of the transmitter signal. The four output signals of the circuit 40 are applied respectively to the phase detector 41, a low pass filter 44 supplying the transmitter 10 and a digital switch 45 supplying the mixers 12, 13, the digital switch 45 being under the control of a level detector 26<SP>1</SP> supplied by the integrator 22. One advantage of this embodiment is that the system is capable of being locked to a reference signal derived from another similar detector. Thus, transmitted signals do not interfere thereby avoiding false alarms. Either of the above embodiments may be combined with the false alarm inhibitor of Specification 1,498,514.

Title: Improvements in or relating to means for producing super- or sub-normal pressure in afluid system
IPC: B64C25/44
Filed: 1930-05-30
Abstract: 355,818. Fluid - pressure brakes. INDIA-RUBBER, GUTTA PERCHA, & TELEGRAPH WORKS CO., Ltd., 106, Cannon Street, and AVERY, W. L., of India-Rubber, Gutta Percha, & Telegraph Works, Silvertown, both in London. May 30, 1930, No. 16750. [Class 103 (i).] A device for expelling fluid from or sucking fluid into a fluid system for operating brakes comprises a piston or equivalent adapted to be moved by an operating lever movable in a direction at rightangles to the direction of movement of the piston &c. and having cam engagement therewith. Fig. 1 shows a device for a pressure system and comprising a pair of coaxial cylinders 25, 26 in each of which works a piston 35 with a screwed-on cap 36 securing a washer 38. Between rings 29, 30 secured to the ends of the cylinders is a spacing ring 31 which extends only partly around so as to leave an arcuate slot through which passes a lever 50 formed integrally with a plate 49. A pivot pin 48 for the plate is mounted in webs extending across the cylinders from the rings 29, 30. Cam members 52 secured to the plate 49 engage rollers 43 on pins 39 passing through the walls of the pistons 35 and through longitudinal slots 40 in the cylinder walls. The arrangement is such that transverse movement of the lever 50 causes outward movement of the pistons by the sliding of the cams 52 on the rollers 43. The cams are so shaped that the leverage on the pistons increases with the extent of movement. A valve 57 for supplying fluid to the system is arranged to be opened by the piston in its retracted position as described in Specification 340,222. In a modification, Figs. 6 and 8, a lever 68 passes through a ring 65 rotatably mounted on the cylinder 61 and abutting on a flange on the cylinder through a thrust bearing 67. The lever passes also through a circumferential slot in the cylinder and triangular apertures 71 in the skirt of the piston 63, the apertures providing cam surfaces 81, 82 engaged by the lever whereby the piston is forced to the left when the lever is turned. The piston is retracted by springs 79 and is prevented from rotation by lugs thereon engaging longitudinal slots 85 in the cylinder wall. The apertures 71 in the piston may be so formed as to provide cam surfaces adapted to move the piston in both directions. A bellows may be used instead of a piston and cylinder. Specification 343,129 is referred to in the Provisional Specification.
