Title: Improvements in or relating to means for counting or segregating of round tablets or balls of equal size
IPC: G06M9/00
Filed: 1946-02-11
Abstract: 607,746. Counting-apparatus. SCHUITEMA, A. Feb. 11, 1946, No. 4216. Convention date, July 17, 1942. [Class 106 (i)] A device for counting or segregating a definite number of round tablets or balls of one size comprises a table on which the tablets are spread and a measuring fork with an open measuring space at one end formed by one or more partitions consisting of parallel strips at a distance slightly greater than the diameter of the tablets whilst their length is an integral multiple of this diameter. As shown in Fig. 2, a measuring fork for manual movement over the table has a measuring space bounded by parallel prongs 1 and intermediate strips 2 forming partitions 3. The open end may be inclined as shown to the axis of the fork or at right angles thereto. The prongs 1 of the fork may have flared ends to facilitate entry of the tablets to the measuring spaces; one of the ends may be pivoted to its prong to facilitate removal of the supernuous tablets. The superfluous tablets may be removed (Fig. 5, not shown) by discharge into a collecting box, a pivoted plate being swung by the measuring fork in its movement along the table into a position to permit the counted tablets to fall into a receiving channel. To prevent the tablets taking up an inclined position or lying one on top of another, the measuring fork may be provided with a transparent cover-plate or a push-off bar may be affixed thereto. A mechanical form of apparatus is shown in Fig. 8 wherein the measuring forks 11 are formed with arcuate spaces 3 and are connected to a rotatable shaft 10. A roller 12 on each measuring fork co-operates with a fixed annular member 13 to impart a to-and-fro movement to the fork during its rotation with the shaft. The counted tablets are discharged through holes (not shown) in the table. In another construction shown in Fig. 9 the operating shaft 10 carries a flanged disc 25 to which the measuring forks 11 are pivoted. Rods 30 on the disc 25 direct the tablets to the measuring forks, those counted pass through an opening 28 in the table to a receiving channel while the superfluous tablets pass through a discharge hole 31. Specification 607,477 is referred to.

Filed: 1974-01-31
Abstract: 1493148 Radiography EMI Ltd 16 Jan 1975 [31 Jan 1974] 04563/74 Heading H4F Apparatus for examining a slice of a body by X- or y-radiation which is of the type described in Specification 1,283,915 in which the body is irradiated with a fan shaped spread of radiation which is detected by a plurality of detectors 18, the radiation source 5 and detectors 18 being orbited around the body so that it is irradiated along a plurality of angular positions and the resulting data from the detectors being processed to derive a reconstruction of the distribution of the absorption of radiation within the scanned body slice, wherein errors caused by sensitivity variations in the detectors are corrected in response to data derived by exposing the detectors to X- or y-radiation from an auxiliary source 29 at at least two positions separated by a predetermined interval in the orbital movement. The two positions are at the start and end of the orbital movement, the auxiliary source 29 being first moved by a nut and screw mechanism to a position in the orbital path of detectors 18 so that at the start of the orbital movement the detectors each successively receive a known number of quanta from source 29. The resulting outputs from the detectors are used to adjust the gains of amplifiers in the detector output circuits to compensate for any differences in sensitivity of the detectors. The source 29 is then withdrawn from the path of the detectors, the source 5 switched on and the orbital examination effected. This examination continues for one full revolution of the source 5 and detectors 18 about the body, and at a convenient time during this revolution the carriage 33 carrying the source 29 is driven along arcuate tracks 35 to the dotted position 33<SP>1</SP> thus putting it in a position just ahead of the detector system 18 when the examination cycle has been completed. When the cycle is completed source 5 is switched off and the source 29 moved into the orbital path of the detectors 18 so that more correction data is derived. Subsequently all parts are returned to their starting positions and the apparatus is switched off. The resulting change (if any) in the measured intensity of the radiation from source 29 by each detector 18 during the orbital movement is utilized to correct the absorption data from the detectors, e.g. assuming a linear drift in their sensitivities over the orbital scanning period. Each detector 18 receives a photon count from source 29 of the order of 10 times or more the count they experience on average per beam absorption measurement during body exploration.

Abstract: 937,520. Coke quenching wagons. ALLIED CHEMICAL CORPORATION. Feb. 7, 1962 [Feb. 27, 1961], No. 4778/62. Class 51 (2). The body 13 of a coke quenching car is mounted pivotally in bearings 22 so that by tilting movement the contents may be discharged through a discharge gate 43 mounted on one side of the body. The gate 43 is hinged at its upper edge and connected by a link 44 to the undercarriage 12 so that when the body is tilted the gate opens automatically. The tilting of the body is effected by a pneumatic or hydraulic cylinder 26 and piston 29 operating through the linkage 34, 35, 38, 39. The two rods 44, 39 are of adjustable length so that the inclination of the bottom 19 of the body may be varied and the position of the gate altered to suit. Inwardly projecting walls 48 form a housing around the rods 44 and protect them from the hot coke. The axis of the pivot on which the body of the car is supported is displaced laterally from the centre line of the car so that any tendency to accidental discharge is avoided. In addition the action of fluid pressure in the cylinder 26 is in the direction of resisting any tilting movement when the body is in the charging position.

Title: Apparatus for measuring the mach number
IPC: G01P5/00
Filed: 1949-02-22
Abstract: 663,287. Measuring Mach numbers. WULFSON, W. Feb. 22, 1949 [Feb. 25, 1948], No. 4849/49. Class 97 (ii). The Mach number of a solid moving rela.- tively to a fluid medium is measured by determining the ratio of the drag coefficients for two aero-dynamically different bodies carried by the solid. One such surface P is blunt in the forward direction and the other Q is sharp-pointed and they may be so selected that the drag ratio P/Q is a linear function of the Mach number M. In the preferred embodiment, the bodies P, Q are each attached to an arm a, only one of which is shown, which are both pivoted to a bracket f mounted in a casing n. The bracket f carries a moving element b which is capable of longitudinal movement in bearings d, e against a spring c by an amount proportional to the sum S of the actual drags on the bodies P, Q. Each arm a is integral with a lever m pivotally connected to a cross-bar g supported by the end of a leaf-spring b, the other end of which is fixed to the bracket f and the cross-bar g is therefore capable of movement transversely of the member b by an amount proportional to the difference S of the drags on the two bodies P, Q. A beam is pivoted at C to the bracket f and intermediate its length has a pin and slot connection with the cross-beam g. Its outer end D partakes of both the longitudinal motion of the element b and of the transverse motion of the cross-bar g and therefore moves through an angle α whose tangent is proportional to the ratio D/S. The Mach number M is determined from the ratio P/Q which is equal to 1+K tan α/1-K tan α where K is a constant. The angular movement of the end D of the beam i may be amplified and utilized to provide an indication of the Mach number by means of a pointer E. Alternatively this angular movement may be transmitted to a distance or utilized to operate a recording mechanism. If desired, the sum and difference factors Sand D may be separately indicated or recorded, and in combination with a thermometer they may be utilized to determine the actual speed of the body.
