Abstract: 634,804. Air traffic supervision; road signals for controlling traffic. STANDARD TELEPHONES & CABLES, Ltd., DUNN, R. H., HERBERT, S., and FLETCHER, J. F. June 19, 1947, No. 16205. [Class 118 (ii)] The passage of an aircraft or vehicle along a runway or road is indicated by means of one or more laryngophones or crystal microphones in vibration-transferring contact with the runway or road. The system for indicating or controlling the movement of cars or aeroplanes along roads or runways described in Specification 576,948 is modified by replacing the microphones used therein by laryngophones or crystal microphones. A number of such microphones 3 are mounted in junction boxes 2 buried in the road or runway 1, the necessary leads being laid in conduits 4. While these microphones will detect the vibrations due to a vehicle passing along the road section in which they are embedded, they are unaffected by sound waves from vehicles passing nearby or aeroplanes flying above them. Alternatively, a metallic rod, tube or strip may be placed across the vehicle pathway or partially or wholly embedded therein with one end of the rod terminating in a laryngophone or crystal microphone mounted in sound-insulating material in an enclosed box.

Title: Improvements in and relating to Coin-operated Prepayment Meter Mechanism.
Inventor: ANDERSON JOHN
IPC: G07F15/04
Filed: 1917-11-07
Abstract: 130,347. Anderson, J. Nov. 7, 1917. Electricity and gas, supplying by meter; coin action, weight. -In a coin-operated prepayment meter of the kind in which the coin itself, in descending into the till, effects the required operative action, a primary coin-operated member and an escapement member are arranged in such a manner that the escapement lever constrains the primary member in position to be struck by a coin falling down the channel, and is deflected from its constraining position by the coin before the primary member is struck by the coin. The mechanism comprises a worm 1 on the spindle 2 of the recording- mechanism engaging a wheel 3 on a shaft 4 carrying a wheel 5 which meslies with a toothed wheel 6 on a fluted spindle 7. The spindle 7 meshes with teeth on the exterior of a screwed sleeve 12 which is traversed on a spindle 9 in one direction by the meter consumption and in the other by the insertion of coins. A control member is provided comprising a plate 46 which engages the sleeve 12 to travel axially therewith and carries a pin 48 which projects into the path of axiallymounted arms 14 and prevents the insertion of more coins when at one end of its travel. At the other end of its path, the member 46 operates the lever 45 to close the gas-delivery valve by means of a rod 49 carrying an index 50. The primary operating-member, in the arrangement shown, takes the form of a number of arms 14 projecting from a disk one of which obstructs a coin channel 15. The normal position of an arm 14 is determined by a pin 16 on the arm which is engaged by a tooth 18 projecting from an escapement lever 20 pivoted at 201. A pin &c. 21 carried by the lever lies in the coin channel and is engaged by a falling coin to operate the lever and release the arm 14, which may then be acted on by the impact of the coin. The primary member may also be in the form of a spring-returned lever driving the shaft 9 by ratchet mechanism. A part of the spindle near the gas cut-out is left plain, so as to prevent jamming in the event of a leakage from the valve. The coin aperture 25 is at the side of the coin channel so that the height from which the coin drops will be always the same. A lever 35 may be provided to direct the coin on to the pin 21. Frand, preventing; diverting improper coins.- In the arrangement shown in Figs. 7 and 8, a plate 27 is pivoted on the coin shoot into which the lower end 241 projects and is engaged by a passing coin so as to bring forward the upper end 242 and block the shoot. In another form, Fig. 6, holes 38 are formed in the sides of the shoot, through which an inserted wire &c. will be guided into channels 42. Small coins miss the lever pin 21 and, being deflected by a curved strip 40, bounce on to a bar 44 fixed to an arm 14 and thence into a receptacle 32, where they are retained by a hinged arm 33 until removed by inserting the finger in an aperture 34.

Title: Improvements in or relating to centrifugal clutches
IPC: F16D43/04
Filed: 1964-04-20
Abstract: 1,047,814. Centrifugal clutches. FICHTEL & SACHS A.G. April 20, 1964 [April 23, 1963; Oct. 8, 1963], No. 16338/64. Heading F2C. A friction disc, claw or coil spring clutch is engaged by a circumferentially yieldable or rigid input-rotated spring-loaded centrifugal mass 16 which, after engaging the clutch is maintained radially outwards hooked to or simply bearing frictionally on a circumferentially-yielding output mounted abutment 31 under a torsion load so that the clutch remains engaged independently of speed until the torque falls to zero. In Fig. 2 (not shown), the mass 16 is carried in a freely-mounted shell 14 and engages the free end 26 of a coil spring 22, the other end of which is secured to the input shaft 10. At a set speed the mass 16 flies out and strikes the output abutment 31 which applies a torque to the coil spring 22 to contract it into engagement with the output shaft 24, the mass hooking at 32 over the abutment 31 to remain outwards independently of speed until the torque is released. The abutment 31 is formed by the end of a spring 30 frictionally mounted on or in the output 12 (Figs. 3-6, not shown). In Fig. 7 (not shown), the mass slides on a radial pin on the input and a notch thereon directly engages an abutment formed by one end of a coil clutch spring the other end of which is fast on the output, whereby the mass twists the spring and contracts it into clutch engagement with the input. In a modification of the latter form, Fig. 10 (not shown), the abutment is formed by an additional spring coil frictionally wrapped around a freely mounted sleeve engaging one end of the coil clutch spring. In a friction disc clutch, Fig. 11 (not shown), the mass 130 slides radially on a sleeve 118, loosely screwed on to the input 114 such that when the mass engages the output mounted abutment 154, the sleeve 118 is screwed axially along the input 114 to bring an end friction face 124 thereon into selftightening clutching engagement with a similar output face 144, the motion of the sleeve 118 being resisted by a spring arm 150 frictionally mounted on the input 114. In Figs. 13, 14 (not shown), pawls carried on axial pivot-pins on the input are permitted to engage output ratchet teeth when a screwed sleeve similar to that 118 in Fig. 11 (not shown), is retracted axially away from them.

Title: Improvements in door and like checks
IPC: E05F3/10
Filed: 1945-10-01
Abstract: 607,937. Door-operating appliances; ball joints. COWEY, L. E. Oct. 1, 1945, No. 16372/47. Divided out of 601,333. [Classes 65 (i) and 65 (ii)] A closing spring and fluid check device is arranged to be attached directly to a gate and gate-post in the same manner as the usual torsion spring, the cylinder and piston-rod being universallyjointed to fixing brackets; the device is inclined to the vertical when the gate is closed, and may be so arranged that no closing force is exerted when the gate is opened through 90 degrees and further opening is assisted. In the arrangement shown, the cylinder 1 is secured to a cap 3 which is balljointed to a fixing bracket 7a, and the piston-rod 5 is similarly jointed to a fixing bracket 7; a sleeve 9 surrounds the cylinder, leaving an annular space through which oil can pass from one end of the cylinder to the other, and carries sealing means 21 engaging the piston-rod. A compression spring 17 is arranged outside the sleeve 9, between the cap 3 and a similar cap 15 carried by the piston-rod 5, and is surrounded by a telescopic jacket 10. The piston 2 has two bores through it, one having a ball valve which permits free passage of oil when the piston moves downwards as the door is opened and the other having a spring-loaded ball valve which opens if excessive pressure is developed during the closing of the door; the passage of fluid past the piston during normal closing occurs through a groove 1a in the wall of the cylinder, the groove tapering to give an increasing checking effect as the door closes. Adjustment of the pressure of the spring 17 is effected by screwing the stud of the lower ball joint in the bracket 7a.

Title: Improvements in or relating to gaskets for use in pipe joints and to pipe joints incorporating such gaskets
IPC: F16L21/03
Filed: 1957-05-24
Abstract: 812,519. Pipe joints. UNITED STATES PIPE & FOUNDRY CO. May 24, 1957 [May 28, 1956], No. 16558/57. Class 99(1). [Also in Group XXVI] A socket 3 has an annular groove 36 in its inner wall which contains an elongated gasket having an axial part 19 engaging the inner wall of the groove and the outer wall 17 of a spigot in radial compression and being more readily deformable than the other axial part near the socket opening which has means 9 for preventing axial movement the internal gasket diameter reducing from a maximum at the socket opening to a minimum at the more deformable part. The spigot abuts the shoulder 5 on assembly indicating required depth of insertion. Before assembly of the joint the gasket is inserted in contact with front wall 11 of the groove so that the means 9 in the form of an annular protrusion of the groove 36 fits into a groove 18 on the gasket. The axial part of the gasket with groove 18 is reinforced by fabric, metal screening or sheet, synthetic plastic, &c. to resist deformation so that it is not displaced when the spigot is inserted. In modifications, Fig. 5 (not shown), a sleeve containing two gaskets connects two pipe ends, Fig. 6 (not shown), the protuberance is on the gasket and fits a complementary groove on the socket, Fig. 7 (not shown), the gasket and socket do not have protuberances or grooves, the gasket being secured in the socket by an adhesive, Fig. 9 (not shown), the gasket comprises two parts without reinforcement, one axial part of relatively rigid material such as rubber having a Shore "A " hardness of about 75-90 and the other axial part which grips the spigot constructed of a resilient material having a Shore " A " hardness of about 40-65, the two parts being integrally bonded together, Fig. 10 (not shown), the gasket has a continuous hole in the thicker portion to permit greater distortion on spigot entry. The outer surface of the spigot and inner surface of the gasket may be lubricated with, e.g. soft soap to facilitate assembly. In Figs. 11, 12 spaced apart holes 28 render the gasket more easily deformable and also serve to distribute the internal pipe pressure to the gasket and increase the sealing properties. In Figs. 13, 14 (not shown), annular ridges are provided on the internal surface of the gasket and a continuous slot replaces the holes 28 shown in Figs. 11, 12. In Fig. 15 (not shown), the resilient part of the gasket is composed of spaced apart sealing lips with a central groove at their juncture. The other axial part of the gasket which is rigid is thereby prevented from blowing out under pressure in the pipes.
