Title: Gyroscope compasses
IPC: G01C19/38
Filed: 1925-08-17
Abstract: 247,265. Swinburne, J. Aug. 17, 1925. Gyroscopic compasses. - In a compass with a balanced gyro - casing, controlled by a level or plummet the tilting of which relatively to the casing operates a relay y controlling means for exerting torques around both the horizontal and the vertical axes, the level &c. also controls a creeping gear for slowly applying a uni-diirectional torque which remains until it is reduced or removed by the resulting tilt of the casing. This creeping gear is employed to apply corrections for changes of latitude and may be applied to a compass having an horizontal axis, or to a compass in which the axis is maintained parallel to that of the earth. The Figures show the application of the invention to a compass of the latter type, the gyro-casing A being pivoted about an horizontal axis B in the plummet element C which is pivoted in the vertical ring G. Secured by arms T to the element C is a plummet H carrying coils I in a magnetic field J. When the coils move within the field a current is induced in them, and this induced current is utilized to operate the torque-applying means and the creeping gear as indicated in Fig. 4. The gyroscope is driven by two phase cuirrent : the coils J are in phase 1 and when' the coils I are displaced a pressure is induced in phase 2. The coils I are in series with coils K, L in the field of a magnet M which is excited by phase 2 so that the current through the coils K, L produces a torque around the horizontal axis. The coils I also supply current to one phase of a two-phase motor N, the other phase being excited so as to produce a torque about the vertical axis. The creeping gear is operated by a two-phase motor F also receiving current from the coils I and operating through reducing gear a pinion gearing with a rack secured to the casing A to vary slowly the tilt of the gyro-axis, equilibrium being reached when this axis is parallel to that of the earth. In the case of a compass in which the gyro-axis is horizontal, the motor F may operate a rheostat in order to vary continuously the current passing through one of the coils K, L.

Title: Improvements in or relating to press for shaping and vulcanizing pneumatic tires
IPC: B29D30/36
Filed: 1955-09-21
Abstract: 793,571. Moulding tyres. McNEIL MACHINE & ENGINEERING CO. Sept. 21, 1955 [Oct. 1, 1954], No. 26969/55. Addition to 769,365. Class 87(2). A press for shaping and curing tyres from bands, in which the shaping and curing medium is in direct contact with the tyre, includes a pair of bead-clamping rings 30, 32, Fig. 5, located between and overlying the edges of the band B. The rings are moved apart, during descent of the upper mould section 2, from the idle position of Fig. 5 to the open bead-clamping position shown in Fig. 2. The means for moving the rings apart is independent of the curing medium, and as shown comprises a fluid-pressure pipe 54, pressure from which raises a piston rod 35 which carries the upper ring 30. The lower ring 32 is carried by the cylinder 40 in which the piston 44 of rod 35 slides. Cylinder 40 is raised and lowered by means of a double-acting fluidpressure cylinder 112 via lever 100 pivoted at 101. When the press is closing, Fig. 5, pressure is released from the upper end of cylinder 112 and the ring assembly drops by its own weight to the dotted-line position, where it remains until the mould sections come into contact around the band. Then the rings are spread apart by pressure from pipe 54 to raise ring 30 and pressure at the lower end of cylinder 112 to pull the ring 32 down. Curing medium then enters the band through pipes 86 and telescopic tubes 88. After curing, the mould section 2 rises, Fig. 7, but pressure is still maintained in 40 and 112 to hold the rings apart, the beads of the cured tyre being thus spread apart to allow water to drain out through openings 60, Fig. 2, in the lower bead ring. The opening movement of the press may be retarded or arrested at the Fig. 7 position to allow this draining. After draining, pressure is released from 40 and applied to the upper end of cylinder 112, whereupon the rings will come together and rise as a whole, thus stripping the tyre from the mould. Specification 691,173 is referred to.

Title: Improvements in or relating to shock absorbers
IPC: F16F9/48
Filed: 1939-10-02
Abstract: 533,048. Shock-absorbers. RIBBESFORD CO., Ltd., and THORNHILL, P. W. Oct. 2, 1939, No. 27035. [Class 108 (iii)] A shock-absorber comprises a cylinder 10 providing a working space 21 for liquid and a plunger 15 providing a chamber 27 into which liquid may be forced through a damping valve 43-45 from the working space 21 causing energy to be stored in resilient means such as air in a space 30 at the top of the plunger, the head 45 of the damping valve co-operating with a pair of opposed non-return valves in the form of rings 50, 51 movable in a passage leading from the working space 21 to the plunger stem 24 and limited as regards movement in an inward direction by a fixed ring 52. The double mushroom head 45 is normally held just seated on the ring 50 by a spring 56. A sudden increase of pressure in the space 21 moves the valve 43-45 to the right and liquid passes freely from the space 21 through the stem 24 into the chamber 27. When the pressure in space 21 begins to fall the valve 43-45 still remains displaced to the right since the increased pressure in the chamber 27 has an action thereon but causes ring 50 to seat on head 45 preventing fluid at this time passing back to the space 21. As soon as the pressure in space 21 drops to about normal valve 43-45 is moved to the left by spring 36 and fluid entering from stem 24 between ring 51 and head 45 pushes back ring 50 and returns to space 21, ring 51 controlling the rate of this flow. In filling the device the air space 30 is determined by a tube 34 engaging a non-return valve 31 fitted to the air space piston 28. Specification 531,099 is referred to.

Title: Improvements in or relating to sieving
Inventor: ALLEN ROBERT WILLIAM
IPC: B07B4/08
Filed: 1969-05-28
Abstract: 1,241,774. Sieving apparatus. H E N R Y SIMON Ltd. 24 March, 1970 [28 May, 1969], No. 27097/69. Heading B2H. A sieving apparatus comprises a sieve 18, means 14, 11a, 11 for delivering stock to the sieve 18, means 12, 12a, 23 and 13, 13a, 22 for conveying the "overtails" and "throughs" respectively separately from the screen, means 28 for forcing a current of air through the sieve co-currently with the "throughs", and means 24, 25 for preventing the air current from escaping respectively with the "throughs" and "overtails". The sieve 18 is disposed in a chamber 10 and forms the upper surface of a subsidiary chamber 19 which is sealed from the interior of the chamber by a wall 20. Stock, e.g. flour, is fed through a hopper 14, an airlock 16, a foraminous, flexible canvas sleeve 17 and a cuff 11a and falls on to the screen. Sieving is promoted by imparting a gyratory movement to the chamber 10. The throughs pass through the screen and fall on a tray 19 and are thence directed towards a port 13 for exit via a cuff 13a, a flexible sleeve 26 and a duct 22 which incorporates a rotary airlock 24. A duct 28 communicating with the duct 22 is connected to an exhaust system whereby air is drawn through the foraminous sleeve 17 into the chamber 10 and passes with the "throughs" through the screen 18. The "overtails" fall off the screen 18 towards a port 12 and exit through a cuff 12a, a flexible sleeve 27 and a duct 23, the latter being provided with a rotary air lock 25.

Title: Screw type connection for connecting a stem member and a bored member
IPC: E21B17/04
Filed: 1938-09-17
Abstract: 519,214. Securing rock-drills to stems. DREWETT, G. Sept. 17, 1938, No. 27199. [Class 124] [Also in Groups XXV and XXIV] A method for connecting a tubular part or socket 12 to a central stem 11 comprises providing' at least one of the parts with a helical groove on the surface facing the other part and interposing between the parts a helicallycorrugated thin metal sleeve, the helical formations being so differentiated that relative rotation of the helical parts causes deformation of the interposed sleeve to bond the socket and stem together. In one form, Fig. 1, in which the stem 11 is hexagonal in section the sleeve has a similar hexagonal form internally to fit the stem, and has a helical rib 14 on the outside adapted to engage helical grooves 17 in the inner surface of the member 12. The grooves, however, are of decreasing depth towards one end of the member 12 so that as the member is rotated, the rib 14 enters the shallower grooves and is distorted to bind the parts 11, 12 together. If the stem 11 and member 12 are both circular in section, an end flange with flats is provided on the member 12 so that its rotation can be prevented by means of a spanner. A wire helix may be inserted in.the interior of the rib 14 for stiffening purposes. In a further modification, the edges of the hexagonal stem may be notched to form an interrupted helical groove 22 which is engaged by an inwardlyprojecting helical rib 14b on the sleeve 13. In this form, the groove 17 has a different pitch from that of the outward rib 14a and the rib 14b and groove 22, so that as the part 12 is screwed on to the sleeve 13 it acts to deform the ribs and cause the desired frictional grip. The sleeve 13 is slit to allow it to be placed over the stem 11. The arrangement may be used in rock drilling for securing detachable bits and separate collars for stems and for securing a drill stem to a detachable socket or shank.

Title: Device for Listening-In to Noises in a Room
IPC: H04M11/00
Filed: 1966-06-17
Abstract: 1,150,430. Automatic exchange systems. AGFA-GEVAERT A.G. 17 June, 1966 [19 June, 1965; 6 April, 1966], No. 27223/66. Heading H4K. A microphone, and, if desired, a loud-speaker, may be arranged to be connected to the exchange-wires at an unattended subset in response to ringing current, or ringing tones, enabling a calling party to listen-in at a location of interest, such as a child's bedroom or where machinery is running. The microphone is connected only after a substantial period of ringing -by which time a caller unconcerned with the listening-in facility should have rung off-and disconnected after a further predetermined period. Connection may be made further dependent upon an additional signal transmitted by the caller such as a verbal command or further digits. In the arrangement shown in Fig. 2 the ring- ing signal is diverted from the subset bell 9 by switch 16, changed over when the subscriber leaves the subset, to operate relay 17 whose contact 17a effects charging of timing capacitor 24. Transistor 20 subsequently conducts after a given period of ringing to operate relay 21 which connects the microphone 27 and loudspeaker 28 across the exchange wires 2a, 2b to complete the D.C. loop. Ringing now stops and relay 17 drops out; relay 21 is now maintained operated so long as timing capacitor 30-previously charged over contact 17c-discharges through transistor 29, after which the microphone and loud-speaker are disconnected and the timing circuit restored to rest by its disconnection from the A.C. supply at contact 21b. In another arrangement (Fig. 3, not shown), the relay 17, unlike in Fig. 2, responds to each burst of ringing current and successively charges a capacitor whose voltage on reaching the threshold of a double-base diode changes over a mono-stable trigger circuit which during its astable state effects connection of the microphone and loud-speaker.
