Title: Frequency deviation detector
Inventor: BARRATT FREDERICK HARRY
IPC: H03D3/14
Filed: 1960-09-14
Abstract: 968,995. Protective arrangements. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Aug. 3, 1961 [Sept. 14,1960], No. 31664/60. Heading H2K. [Also in Division H3] An alarm or relay circuit is energized by a bi-stable circuit when a frequency deviates from a nominal value. The frequency is applied through a transformer to a centre-tapped secondary, one half of which is shunted by a circuit 6, 7 series resonant at the nominal frequency so that its tapped output varies in phase with frequency variations, relative to the other secondary half output. Both outputs are then applied through resistors R2, R3 to transistor bases shunted by biased normally conductive rectifiers 12, 13 so that a square wave output is provided from the common collector circuit of the transistors, when both are non-conductive, of duty cycle duration dependent on the phase difference between the inputs. This is integrated to produce a negative voltage across capacitor C, (instead of normally earth potential), which, applied to cross-coupled transistor bi-stable circuit 13, 14, cuts off normally conductive transistor 13 and renders transistor 14 conductive so that relay 15 is energized. The circuit may be re-set manually or by relay 15, or a subsequent circuit breaker. A capacitor also may shun the base/emitter path of transistor 13.

Title: Improvements in or relating to the hydration of lime
IPC: C04B2/08
Filed: 1947-12-02
Abstract: <PICT:0637756/III/1> Lime is hydrated by passing it with water through a conveyer A into a vessel B to form a fluidized bed C, which is further fluidized by the passage therethrough of inert gas, e.g. steam or air, from fan D, the fine particles being thereby separated from the coarse, and being carried away in suspension through openings F.  The temperature is maintained slightly above 100 DEG  C. by control of the water supplied.  Unhydrated residue is removed through rotary valve J.  Openings F are formed with deflecting plates F2 to impart a circular motion to the gases, the cyclone action resulting causing the lime to separate; it is removed through opening H.  The gases pass to a fan washer L and thence to a baffle-box M, the water separating being returned to the conveyer A, and the gases passing to the inlet of fan D.  When the plant is started, air may be circulated, to be later replaced by the steam evolved.  Excess air and steam may be voided through valve P.

Title: Improvements relating to the manufacture of sponge rubber
IPC: C08L21/00
Filed: 1948-12-13
Abstract: Porous or cellular natural or synthetic rubber products are obtained by incorporating a salt of urea with an organic acid such as oxalic, succinic, tartaric or citric acid into the rubber mix and then vulcanizing at a raised temperature.  The preferred salt is urea oxalate which may be obtained by precipitation in the presence of a protective colloid such as casein, sodium alginate or bentonite and may then be coated with a fatty acid.  In examples 1-5, urea oxalate, succinate, citrate or tartrate is added to a natural rubber mix containing smoked sheet or pale crepe rubber and substances chosen from zinc oxide, semi-reinforcing furnace black, stearic acid, sulphur, whiting, titanium oxide, petroleum jelly, diphenyl guanidine, ebonite dust, softening agents and magnesium oxide were vulcanized to give cellular products.  In example 6, a neoprene sponge was produced from Neoprene G.N., peptiser, light calcined magnesia, soft carbon black, zinc oxide, mineral oil, stearic acid and coated urea oxalate.  The Provisional Specification also specifies stearic acid as the fatty acid which may be present when the urea salt is precipitated.
