Abstract: 917,631. Protective arrangements. WHIPP & BOURNE Ltd., and WHIPP, C. L. Feb. 24, 1959 [Feb. 25, 1958], No. 6024/58. Class 38 (5). An anti-pumping circuit-breaker control system comprises an electrically-controlled device C for closing the circuit-breaker, a contactor A for controlling the device C, a manual switch 22 for controlling the contactor, and a relay B which is initially controlled by the device C and has maintaining contacts B1 and normally closed contacts B2 in series with the contactor A. When the switch 22 is closed the contactor A closes its contacts A1 to energize the device C. The device C closes the circuit-breaker and closes contacts C1 to energize the relay B which opens contacts B2 to de-energize the contactor A and closes the maintaining contacts B1. Should the circuit-breaker trip open whilst the manual switch 22 is held closed, the circuit-breaker does not automatically reclose as the relay B at contacts B2 prevents the reclosing of the contactor A. Contacts 23, closed when the circuitbreaker is closed, complete a holding circuit for relay B when the switch 22 is released. Should the contacts C1 re-open when the circuit-breaker is closed with the device C de-energized, then further contacts 24, closed by the circuitbreaker when closed, are provided. Alternatively a single set of contacts operated by the circuit-breaker may be connected across the switch 22 and contacts B1.

Abstract: 985,284. Controlling aircraft. MESSER SCHMITT A.G. Feb. 19, 1962 [Feb. 18, 1961], No. 6263/62. Heading B7G. [Also in Division G4] An interceptor aircraft carrying ballistic missiles is controlled to fly a course such that at any time a missile may be fired, and will then fly a collision course to the target, the course direction # being governed by the equation: where # is the bearing of the line of sight from the aircraft T to the target Z from a fixed (e.g. gyrostabilized) direction Br, s is the range of the target and # its bearing from the direction of the interceptor course, w and v are the speeds of a missile and the target respectively, and k 1  and k 2  are constants. In the computer of Fig. 3, f(w, v) is taken as w - v, computed from assumed values of w and v by amplifier S 1 . A function generator FG derives sin 9 from the value of # available from radar equipment, and a multiplier M 1  derives - (w - v) sin #. A multiplier M 2  derives - sd#/dt from s and d#/dt signals available from the radar equipment so that summing amplifier S 2  derives e = sd#/dt + (w - v) sin #. When the interceptor is flying the desired course, e = 0. The value of # is sealed by the factor k 2 , and k 1  added in amplifier s 3 . The sum is multiplied by dx/dt in multiplier M 3 , and the result is fed to the aircraft control system as the demanded value of d#/dt.

Title: Continuous manufacture of polymeric materials from polyesters and organic di-isocyanates
Inventor: BELLIS ARTHUR JOB DANIELS
IPC: C08G18/08
Filed: 1955-03-04
Abstract: Polymeric materials are continuously prepared by injecting polyesters and organic diisocyanates in the presence of catalysts, and optionally of water, simultaneously or consecutively into a mixing chamber, without using high pressures as in Specification 769,680, and continuously flowing the liquid reaction mixture out of the mixer and shaping it into articles, blocks or continuous sheets.  The starting materials may be the ones usually employed in this art or may include polyesters as described in Specification 790,420. Emulsifying agents may be included, e.g. turkey red oil, oleic acid partially neutralized with diethylamine, cetyltrimethylammonium bromide, oleyl sodium sulphate or ethylene oxidealkyl phenol condensates.  When making cellular products, bulk density may be controlled by varying the amounts of water and diisocyanate employed. Blowing may also be controlled by addition of acids, e.g. benzoic, salicyclic, terephthalic, or phosphoric.  Fillers, colouring matters, flame-proofing agents or other inert materials may be added, e.g. as dry powders at any appropriate stage.  In examples: (1) a catalyst mixture of water, alkyl phenolethylene oxide condensate, and di-(b -diethylaminoethyl) adipate, together with toluylene-2,4- and -2,6-diisocyanates, are continuously blended in a mixing chamber with a liquid polymer from diethylene glycol, pentaerythritol and adipic acid, and the fluid blend is discharged continuously into moulds and left to stand at room temperature to form resilient cellular articles; (2) is similar but uses a catalyst mixture of water, the sodium salt of oleyl-p-anisidine sulphonate and N,N-dimethyl cyclohexylamine and a polyester formed from diethylene glycol, glycerol and adipic acid and previously mixed with copper phthalocyanine.  In Example (3) the catalyst mixture contains water. N,N-diethylbenzylamine, and diethylamine oleate.  Benzoic acid is dissolved in the liquid polyester used.  Example (4) prepares rigid cellular articles by using a polyester from adipic acid, phthalic acid and hexanetriol, a catalyst mixture of water, octyl phenol-ethylene oxide condensate and N,N-dimethylcyclohexylamine, and different proportions of reactants.  Example (5) uses a dried polyesteramide from ethylene glycol, monoethanolamine and adipic acid together with mixed toluylene-2,4- and -2,6-diisocyanates to produce resilient rubber articles.  In Example (6) a mixture of liquid polyester, water, oleic acid partially neutralized with diethylamine and di-(b -diethylaminoethyl) adipate is continuously blended in a mixing chamber with a mixture of toluylene-2,4- and 2,6-diisocyanates.  The fluid blend is continuously discharged into moulds to produce resilient cellular articles.  The Specification describes suitable mixing apparatus (see Group II) for the performance of the invention.  Specifications 553,733, 579,340, 659,344, 759,540 and 839,187 also are referred to.
