Class 40(1) [Also in Groups XXVI, XXIX and XL(b)] A fluid rate of flow meter comprises a conduit through which all or part of the flow to be measured passes a venturi in the conduit, a meter wheel is pivoted about an axis at right-angles to the direction of fluid flow and tangential to the venturi throat, the meter wheel having a maximum radius smaller than the diameter of the venturi throat and having no mechanical connection with the outside of the conduit, and photo-electric means for indicating the effect of flow variations in the conduit on the meter wheel. One form of flowmeter, Fig. 1, comprises a venturi sleeve 3 fitted within the conduit 1 and a four-bladed meter wheel 2 which is pivoted about an axis 6. A casing 11, attached to the conduit 1 contains a light source 12 from which a beam is directed through a window 9, in a recess 7, and is reflected from the edge of each blade of the wheel as it passes the window, the reflected beam falling on a photo-multiplier 16 for indicating the speed of rotation of the wheel. The wheel 2 may be of stainless steel or of tetrafluorethylene resin with, as shown in Fig. 4, the ends of each blade drilled to take a stainless steel wire 23 which is then cut to form a reflecting surface 20. In a second form, Fig. 3 the velocity of fluid flow is increased by means of a double conical body 4 and the wheel is fitted at the throat of the annular venturi so formed. The ratio of the minimum and maximum diameters at the throat is preferably 0.2 and the apex half-angles of the convergent and divergent portions are preferably 14 degrees and 7 degrees respectively.

IPC: G01C19/28
Filed: 1956-03-07
Abstract: 841,944. Electric transducers. SPERRY GYROSCOPE CO. Ltd. March 7, 1956, No. 7239/56. Drawings to Specification. Class 40 (1). In a gyroscope, the rotor case is supported inside a housing by a gimbal system, the space between being filled with mercury which provides a number of electrically-conductive paths for electrical signals developed in pick-off devices used to detect the relative movement of the casing and housing. At each pick-off, a U-shaped duct in the housing is filled with mercury and is magnetically-coupled, by an iron core, to a winding. The latter forms the primary of a transformer, the secondary of which is the mercury filled duct. Movements of the rotor case adjacent the duct, change the dimensions of the mercury path and hence produce a corresponding change in the primary winding impedance. Specification 741,960 is referred to.

Abstract: 1,020,337. Solid fuel firegrates. RADIATION Ltd. Jan. 7, 1965 [Feb. 21, 1964], No. 7276/64. Heading F4W. In a firegrate bottom of a solid fuel fire or stove consisting of an outer frame and a centrepiece 2 resting on four points 3, 4, 5 and 6 and connected to the outer frame at a pivot 8, oxidation, scaling and distortion of the firegrate is prevented by using a material of high heat resistance such as 30% chromeiron. Either centre-piece 2 only or both the outer frame and the centre-piece may be made of the chrome-iron, or the outer frame may be made of a chrome-iron of lower chromium content than that used in the centrepiece. Adequate clearance is left at the four supports 3, 4, 5 and 6 to allow for differential expansion and slight rotation around the pivot 8. The complete firegrate bottom is mounted in horizontal runners set at each side of a fire box structure enabling the assembly to be reciprocated backwards and forwards for shaking out ash.

Title: Improvements in and connected with pneumatic mechanism for operating peals or carillons of bells or single bells
IPC: G10K1/34
Filed: 1923-03-14
Abstract: 216,252. Johnston, C. F. March 14, 1923. Bell-operating mechanism, pneumatic.-In a pneumatic bell controlled by an electricallyoperated valve, the base of the mechanism constitutes a storage chamber for compressed air, whilst the control valve is operated by a solenoid or magnet placed axially with respect to the valve which it operates through a rod attached to or forming part of the core of the solenoid or the armature of the magnet. In one arrangement. Fig. 1, the valve comprises balls 10, 11 separated by a distance piece 12 and controlled by the armature 15 of an electromagnet 14 and by a restoring spring 13. The closure of switch 21 opens valve 10 to supply compressed air from the storage chamber 2 located in the base of the apparatus, to the cylinder 3, so that the piston 4 moves downwards and, by means of the pivoted lever 6, imparts an impulse to the bell. When the switch 21 is opened, spring 18 restores the lever 6 and piston 4, and the cylinder 3 is connected to the exhaust port 8. In order to obtain automatic repeated ringing, a second switch 27 is provided in series with interrupter contacts 24, 25 which are opened during the downward movement of the rod 5. In a modification, the piston is directly connected to the bell, the lever 6 being eliminated. The bells may be employed in carillons, the various switches being automatically operated by a perforated paper strip. One of the Provisional Specifications refers to means for adjusting the interrupter contacts so that rapid blows of short stroke or slow heavy blows of long stroke may be given to the bell as desired.

A collet for use in a collet chuck comprises a number of wedge-shaped members 1a, Fig. 1, held by rings 4, 5 to form a number of circumferentially-spaced slots 1b to receive jaws 6, the conical surface formed by the members and jaws engaging a complementary surface 6a in the chuck-body 17. The jaws have openings 7 engaged by the ring 5 and are moved in unison along the surface 6a to thereby move radially inwards to grip a work-piece by a ring 12 having projections 13 which engage the jawends between the members 1a. The ring is prevented from turning by pegs 15 and is moved axially by a ring-nut 19 engaging threads on the body 17. The jaws are urged in the direction to release the work by springs 11. In a modification, the jaws project from the ends of the slots to engage a cup-shaped member movable axially by a ring-nut splined to the body 17. In another arrangement, the jaws 106, Fig. 2, are fixed by projections 107 between a washer 108 and a ring 100 to a sleeve 81 having fingers 83 engaging splines in the body 17<SP>11</SP>. The sleeve is moved axially relatively to the body by toggle levers 91a, 91b acting between an adjustable abutment 92 and a pin 90 fixed to the sleeve. The toggle is moved by a cam surface 98 in a sleeve 97 engaging a roller 91c at the pivot-point of the levers, the sleeve being slidable by handle 101 moving a yoke 104 pivoted at 103 and having projections 104a engaging a groove 104b in the sleeve. There are preferably three peripherally-spaced sets of toggle levers, each housed in a recess 88 in an outer fixed sleeve 87. A ring 109, e.g. of rubber, may be provided in a groove between the jaws and the ring 100 to prevent entry of swarf into the collet. The ring 109 may be backed by a number of segments bonded thereto and surrounded by a spring circlip.

If the barrel surface is irregular, true driving surfaces are provided by attaching by hard pointed screws C, Fig. 3, a pair of turned cast iron &c. rings MR, one on each end of the barrel, the rings being connected by stays S parallel to the barrel axis. If the barrels require ventilation, orifices at the centres of the ends of the barrels are presented to the ends of pipes passing through standards T and the hollow frame AT to a fan. Inward leakage is provided in the system to remove dust from the air surrounding the barrels.

Class 103(1) Fluid pressure operated brake control apparatus for hoist and winding mechanism of the type wherein a cam disc 11, geared to the winding shaft, causes alteration of the position of a valve mechanism 17, 18 so that the flow of oil to the brake cylinder is restricted except at the beginning and end of a wind so as to limit the pressure applied to the brakes, is further controlled in accordance with the direction and speed of winding. As shown in Fig. 1, this further control is provided by means of a hydraulic coupling 1 rotated by the winding shaft, which when the speed is sufficiently great raises a weight 4 to close a valve 5 in the pipe joining inlet and outlet chambers 33 and 34 of the governor valve 6. The raising of the weight is permitted on a raising wind but prevented by means not shown on a lowering wind. In the arrangement shown in Fig. 2, the valve 5 is controlled by a piston 21 moved in a cylinder 22 when a pump 28 rotated by the wind shaft produces a certain pressure corresponding to a certain speed of winding. When lowering, the pump 28 sucks liquid from the reservoir 23 and therefore the valve 5 is not closed.
