Abstract: 1,117,673. Measuring flow or velocity. CHESAPEAKE INSTRUMENT CORP. 28 Dec., 1965 [28 May, 1965], No. 54985/65. Heading G4H An A.C. signal of variable amplitude representing the velocity of a ship or fluid flow in a pipe is derived by a sensor and is applied to the secondary windings of a transformer which acts as a comparator. An A.C. reference signal derived from a counter is supplied to the primary winding of the transformer so that an error signal is produced, this being rectified and enabling one of two gates depending on whether the signal from sensor is larger or smaller than the reference signal. Pulses of corresponding amplitude are passed by each gate to an associated threshold device supplying the add or subtract input of the counter. Each binarycoded decade of the counter controls a summing network supplied with binary-weighted A.C. signals; the outputs of these networks being decimal weighted and summed to provide the reference signal to the primary winding of the transformer. A speed indication is derived from decoders. An integration with respect to time is performed to indicate total flow or distance travelled. A second counter is continuously cycled by a clock pulse source, supplies a binary-coded decimal output to comparator gates and sets a bi-stable circuit once in each cycle. When the contents of the first and second counters are the same, the bi-stable circuit is reset. In the period for which the bi-stable circuit is set, clock pulses are fed to a third counter via a sealing circuit so as to accumulate the integrated measurement. Means are provided for zero adjustment and calibration tests.

Abstract: 1322864 Regeneration of foundry sand SOC D'APPLICATION DE PRODUITS INDUSTRIELS ET CHIMIQUES SARL 29 Nov 1971 [30 Nov 1970] 55181/71 Heading B2H [Also in Division B3] A process for the regeneration of foundry sand comprises breaking the moulds, crushing the hot lumps of sand obtained therefrom, cooling the crushed sand to ambient temperature, separating the grains of sand from their coating of a binding agent by projecting them against the wall of a chamber to cause the matrix of binding agent to burst, submitting the sand thus obtained to granulometric selection by at least two screens, and removing dust from the sand in at least one stage of the process, where the dust is formed. After the mould has been broken up using a stationary, vibrating or impact type grid 1, the sand is gushed in the unit 2. and passed through a sand cooling unit 3 which is preferably of the fluid bed type. It is then carried to the top of a device 6 by a conveyor 4 provided with a separator for metalic particles, and an elevator 5. In the device 6, Fig. 4, the sand is subjected to horizontal jets of air issuing from pipes 9 which force the sand against baffles 8. A fine spray of water may be introduced into the device 6 from an atomiser 15 for cooling purposes. Dust is withdrawn through an outlet 11 whilst the sand passes through an outlet 12 to a screening apparatus 17 having between two and eight screens arranged above one another. From here the coarse fraction is either collected in a hopper 25 or conveyed to a secondary crusher 22 and reintroduced into the bottom of the elevator 5. An intermediate fraction is collected in a hopper 19 and reused in the manufacture of moulds, and a very fine fraction is drawn off into a chamber 26. The dust produced in earlier stages of the process is also conveyed to the chamber 26, where it is removed in filter sacks 26a or in a wet separation apparatus.

Abstract: 1,202,727. Recording the operation of machines. FRONTIER ELECTRONICS Inc. Dec.8, 1967 [Dec.27, 1966], No.56010/67. Heading G1J. A system for monitoring the operation of a number of machines such as looms comprises a multiple pen recorder A, the pens 20 of which are in contact with a moving paper 21, electromagnetic means B for controlling the position of the line each pen draws and a signal generator E coupled to each machine for generating signals identifying the cause of shut down of a machine. Each loom has a switch which operates on breakage of the worn yarn and a switch which operates on a breakage of the filling yarn. A further switch is also provided for manually stopping the loom and the three switches are connected in the transistor circuit of each signal generator. If, for example, the worn yarn breaks on a particular loom relays in the corresponding signal generator open the manual switch to shut down the machine and connect the pen to an oscillator in the signal generator so that a trace 22 is produced. When an operator reaches the loom, he depresses an interrupt button connected to the signal generator to temporarily return the pen to its initial line, thus recording by the part 32 of the trace, the length of time that the machine is closed down. The operator then repairs the breakage and the portion 33 of the trace records the time taken to repair the breakage. Similarly a trace 23 is recorded if the filling yarn breaks, however the oscillator output frequency is changed so that the loom fixer can tell from the trace which type of fault has developed. A third trace 24 is recorded when the machine is stopped for any other reason such as by actuation of the manual switch. Circuitry is also provided for recording the total shut down time of a group of machines, each machine having the contacts of one of the relays in its signal generator scanned once per minute for determining if the machine has been shut down. The scanner feeds counters so that the total shut down time of the machines may be determined. Similarly, circuitry is also provided for recording the number of times the machine or groups of machines have been shut down due to a particular cause.
