Inventor: HELLIWELL GUY STORR
IPC: F04D29/50
Filed: 1962-01-11
Abstract: 984,235. Centrifugal pumps. SAMUEL PEGG & SON Ltd. Jan. 3, 1963 [Jan. 11 1962], No. 1045/62. Heading F1C. A centrifugal or other impeller-type pump comprises a casing having ports connectible to liquid flow conduits, a rotatable hollow valve shell mounted around the impeller and having a transverse internal partition which divides it into two compartments, viz., an outlet compartment which directly surrounds the impeller, and an inlet compartment in communication with the impeller eye, each compartment being furnished with aperture means for registration with ports in the casing, and means for turning the valve shell to bring the aperture means into registration with selected ports in the casing thereby to change over the direction of liquid flow through the ports and conduits thereto. In the centrifugal pump shown, the impeller 6 rotates within an inner cylindrical casing 12 which is mounted concentrically within an outer cylindrical casing 8 by means of stays 13, 13<SP>1</SP>, 13<SP>11</SP>. A control valve comprises a cylindrical shell 18 fitting within the inner casing 12 and carried by a disc 19 mounted on a spindle 23. The shell 18 is divided into two compartments A, B by means of a conical partition 26 disposed adjacent the front of the impeller. When the shell 18 is in the position shown, ports 29 and 30 in it are in alignment with ports 33 and 32 respectively in the inner casing 12. As shown by arrows C, liquid then enters the pump through a conduit 10 and passes through the ports 32, 30 and a central opening 27 in the partition 26 to the eye of the impeller. The impeller discharges the liquid through the ports 29, 33 to a conduit 9. When the valve is turned by means of a handle 25 to an alternative position in which the ports 29 and 30 align with ports 34 and 31 respectively, the flow through the conduits 9, 10 is reversed, as shown by arrows D. The flow can be throttled by turning the valve to vary the overlap between the ports in use.

Patent GB-973292-A (GB)
Title: Improvements in the treatment of foundry sand
Inventor: BARLING THOMAS PERCY
IPC: C08K5/43
Filed: 1962-01-11
Abstract: Foundry sand is treated to render it capable of use without baking for the preparation of foundry moulds or cores by mixing the sand with a liquid capable of polymerizing to form a furane or urea formaldehyde resin and with aminosulphonic (amidosulphuric) acid as an activator for the resin.  The mixture contains resin in an amount 1-5% by weight of the sand and amino-sulphonic acid in an amount of 20-40% by weight of the resin, and preferably the sand is first mixed with the amine sulphonic acid in a mixer, the liquid resin is then added to the mixer, and the mixing continued. The resin binder may comprise a mixture of urea formaldehyde and furane resins or may contain phenol formaldehyde resin as a diluent.  It may also contain oleaginous diluents e.g. tung oil and linseed oil but any diluents are added in such amount, e.g. not exceeding 40% by wt. of the furane resin, that it is still unnecessary to bake the mould or core to ensure setting.  If desired, the aminosulphonic acid may be treated to render it free flowing as described in Specification 973,293.

Title: Method of drying and roasting or roasting and sintering
IPC: C04B7/44
Filed: 1952-01-15
Abstract: High melting silicates, oxides, carbonates and other substances such as clay or mixtures of substances such as lime and sand with a similarly high melting point are dried and roasted or roasted and sintered when mixed with fuel and return material and in layer heights of up to 30 cms., by a downward blast roasting process characterized in that in order to recover return material only from the lowermost layer of the material undergoing treatment, said lowermost layer is prepared from raw material without the admixture of fuel or return material and consists of particles of such a size that it goes completely into the return material on screening.  It is preferred to establish a ratio of 1 : 2 to 1 : 4 between the amounts of raw material present in the fuel-free lower layer and the fuel-containing upper layer.  Pulverulent raw material may be mixed with water, dusted with more raw meal, nodulized and, if desired, dried before roasting, the maximum grain size being adjusted to pass through, e.g. an 8 mm. sieve. The invention also applies to the production of cement and in the example raw cement meal is sprinkled with water in a worm mixer to give granules having a water content of 16.5 per cent.; these are dusted with 1.7 kg. of raw meal for 5kg. of said granules, and nodulized to give firm nodules with 11.5 per cent. water content. Roasting after drying is performed with a layer height of 30 cms., of which 5 cms. is taken up by the lower layer.  8 per cent. of coke slack, and return material in a 1 : 1 ratio is added to the upper layer.ALSO:Raw materials for the preparation of cement are dried and roasted or roasted and sintered when mixed with fuel and return material and in layer heights of up to 60 cms., by a downward blast roasting process characterized in that in order to recover return material only from the lowermost layer of the material undergoing treatment, said lowermost layer is prepared from raw material without the admixture of fuel or return material and consists of particles of such a size that it goes completely into the return material on screening.

Patent GB-852640-A (GB)
Title: Voltage generating and voltage comparison circuits
Inventor: RUSSELL GRAHAM
IPC: G06G7/52
Filed: 1956-07-05
Abstract: 852,640. Electric analogue calculating. NATIONAL RESEARCH DEVELOPMENT CORPORATION. July 2, 1957 [July 5, 1956], No. 1250/60. Divided out of 852,639. Class 37 [Also in Group XXXV] A conditional probability computer for the automatic control system set forth in Specification 852,639 (see Group XXXV) comprises interalia a number of basic units each comprising a reservoir and bucket capacitance voltage generating circuit associated with a comparison circuit, each of which generates a voltage logarithmically related to the occurrence of the input pulse signals applied thereto, the generated voltages of any two units then being compared to obtain the conditional probability of the occurrence of input pulse signals at one unit relative to the occurrence of the input signals at another unit. In Fig. 3, relay XYZ is normally held operated by a monostable flip flop circuit comprising valves VA, VB. At the occurence of an input pulse at the count-in point C, the monostable circuit is operated to de-energize the relay XYZ, whereupon control XYZ5 changes over to disconnect condenser BCA from point C and connect it to condenser CPA, whereupon condenser BCA removes part of the charge acquired by the condenser CPA. Disappearance of the input pulse allows the relay to be re-energized contact XYZ5 to resume the position shown, condenser CPA to resume charging, and condenser BCA to discharge through rectifiers MRB. The frequency with which the pulses are applied at C will thus govern the charge acquired by condenser CPA and hence the voltage Vi at the cathode of the valve VC. This voltage is fed simultaneously to a point x and to a second counting circuit comprising condensers BCB and CPB, wherein the relay XYZ operates contacts XYZ3 to connect the condenser BCB alternately to the condenser CPB and to the cathode of the valve Vc, thus generating a second voltage Vt which is added to the generated voltage Vi by a sampling condenser KS and further contacts XYZ2, XYZ4 of the relay XYZ. The voltage (V i   + V t) approximates to a logarithmic function of the occurrence of the pulses at C. The generated voltage (V + V t ) is fed by way of an output terminal So to the input terminal S i  of another similar unit whereby it is compared by simple subtraction with the voltage Vi generated in that circuit at x thus indicating the conditional probability of the occurrence of input signals at one circuit relative to the occurrence of input signals at the other unit. Simplified forms of the device are set forth in Fig. la, 2a (not shown).
