Title: A foundry molding-machine
IPC: B22D13/10
Filed: 1955-04-27
Abstract: 808,348. Centrifugal casting-machines. HERMAN PNEUMATIC MACHINE CO. April 27, 1955 [May 5, 1954], No. 34964/56. Divided out of 808,345. Class 83 (1). In a centrifugal casting- -machine, particularly for casting pipes, an open-ended flask is rotatable in a cradle so that, after introducing sand &c. into the flask, and inserting a mandrel axially therein, the cradle may be rocked relatively to the mandrel, to cause the latter to consolidate and shape the sand whilst the flask is rotating. One or more flasks 16 are rotatably mounted in a cradle 11 which is carried by a pivot 8 on a support 7. Trunnions 6 on support 7, at right angles to pivot 8, are rotatable by fluid motors 5 to locate the flasks either vertically, as shown dotted in Fig. 2, or horizontally. A carriage 23, slidable along ways 22 on the machine bed 3, carries rotatable mandresl 25 corresponding to flasks 16. In operation, with the flasks 16 vertical after having discharged castings and moulds therefrom, the lower ends of the flasks are closed by plates 44, Figs. 3 and 5, which are rotatably mounted on a twoarmed spider 34 oscillatable and axially slidable on a shaft 31 carried by cradle 11. When this shaft is turned by a fluid-vane 32, a spring 38 maintains a stop 46 on the arm 34 in contact with a stop 45 on a cam 36 secured to the shaft, so that the arm and cam rotate together. After 90 degrees of rotation, the plates 44 are opposite the flask-ends and further rotation of the arm is prevented by a stop, but the shaft 31 continues to rotate cam 36 against a cam 37 secured to the arm, so that the latter is moved axially, under the influence of spring 38, to press the plates against the flask ends. Sand is the introduced into the upper ends of the flasks and the latter are rotated about their axes by a motor 17 whilst the support 7 is rotated about trunnions 6 to bring the flasks horizontal. The plates 44 are removed from the flasks by reverse rotation of shaft 31 and the mandrels 25 are introduced axially into the centrifuged cavities in the moulds by movement of carriage 23 through a fluid cylinder 26. The cradle 11 is then rocked about pivot 8 by fluid cylinders 15, Fig. 3, whereby the mandrels smooth and consolidate the sand and form socket and core cavities at one end of the moulds and spigot recesses at the other ends. The cradle 11 is then restored to normal position by cylinders 15, and the moulds are ready for casting. Means for applying cores to the ends of the flasks and for pouring the metal are described and claimed in Specifications 808,345 and 808,347.

Title: Balanceable electrical network
Inventor: JR DONALD MCKINLAY
IPC: G01F1/37
Filed: 1958-10-31
Abstract: 862,450. Electric measuring systems. BRISTOL CO. Oct. 31, 1958, No. 34981/58. Addition to 734,999. Class 40 (1). [Also in Group XXXVI] A self-balancing bridge circuit for determining fluid flow in a conduit 20 (Fig. 2) by allowing the pressure difference across a restriction 21 to adjust the slides of a potentiometer 151 comprises two automatically adjusted potentiometers 110, 115 whose sliders 111, 116 are mechanically linked to give a square law displacement characteristic, the ratio of the resistance of the detector 136 to that of potentiometer 115 being chosen to give a substantially constant measurement sensitivity. The pressure difference across the restriction 21 displaces an arm 25 attached to the slider 152 of potentiometer 151 connected in a bridge circuit with the balancing potentiometers 110, 115. The potentials at sliders 152, 116 are fed in opposition to the detector 136 which energizes a motor 138 to drive sliders 111, 116 together to the balance position, the displacement being linearly related to the fluid flow. It is shown that the sensitivity of the detector depends on the ratio of the detector resistance to that of potentiometer 115, and varies with displacement, but for values of this ratio less than one-tenth it is substantially constant over most of the working range. In a modification (Fig. 5) additional potentiometers 146, 149 are added to enable the use of sliding contacts instead of flexible leads, potentiometer 149 also producing a reduced sensitivity for large displacements. Specifications 568,204 and 703,772 also are referred to.

Title: Improvements in or relating to arrangements for recording variations in the electrical resistance of the human body
IPC: G01R27/02
Filed: 1947-12-31
Abstract: 631,925. Resistances measuring. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. Dec. 31, 1947, No. 35196. Convention date, Sept. 6, 1945. [Class 37] Variations in the resistance of the human body due to heart - beats are measured by applying H.F. oscillations from a valve oscillator to the body in series with a constant resistance, and feeding the resulting amplitude-modulated oscillations to an oscillograph together with out-of-phase oscillations from the oscillator, so as to reduce the effect of variation of amplitude of the oscillator. Oscillations from 1 are applied to the body between terminals 11, 10 and over resistance 9 in opposite phase to resistance 23; resistance 9 is preferably lower than the body resistance; the voltage across resistance 23 is rectified at 13 and applied, over network 12 ... 17 to eliminate H.F., to a valve 20 of the oscillograph 19. If the oscillator 1 is energized with rectified and smoothed A.C., any variation is removed by applying A.C. of the same frequency from 30, 31 over resistance 32 and phase-shifter 33 to the output circuit of rectifier 13. The network 12 ... 17 may be tuned by choice of one of condensers 25, 26, 27 to reduce variations, e.g. due to breaking, at frequencies other than the frequency of heart-beats. Resistance 36 may be switched in and out for calibrating the oscillograph.
