Compositions, as follows, are given in the Examples: (1) the active ester (25% w/o) in solution in diethylcarbital; (2) the active ester (20%) with ethylene oxide-octyl phenol condensate containing 10 mols ethylene oxide per mol. of octyl phenol (5%), and oleic acid-ethylene oxide condensate (5%) in a 4 : 1 by volume mixture of acetophenone and toluene.
Patent GB-982619-A (GB)
Title: Locking stays
Inventor: FERNBERG PAUL CARL ROGER
IPC: E05C17/32
Filed: 1963-01-31
Abstract: 982,619. Locking stays. F. T. PRODUCTS Ltd. Jan. 27, 1964 [Jan. 31, 1963], No. 4091/63. Heading E2F A stay comprises two members held in sliding contact so as to be pivotally or rectilinearly movable relative to each other in a defined direction and arranged to be locked in one, two or more positions relative to each other. In one embodiment, Fig. 1, the stay comprises two arms 11, 12 spring-urged together on a tubular pivot 13, the arm 11 including a slot 15 having a notch 16 having teeth 19, 20, and the arm 12 including a slot 21 having a notch 22, a flanged locking pin 26 passing through the slots 15, 21 and being urged radially inwards towards the pivot 13 by springs 27, 28. When the arm 12 has been rotated clockwise relative to the arm 11 through about 90 degrees, the notches 16, 22 are then in register so that the pin engages the notches and locks the arm 12 against anticlockwise movement, since side wall 17 of the notch 16 is undercut and side wall 24 of the notch 22 is substantially radial. On further clockwise rotation of the arm 12, oblique walls 23, 18 of the notches 22, 16 cam the pin 26 radially out of the notches, and the pin is moved along to the end of the slot 15 where it is in an overcentre position. As the arm 12 is rotated anticlockwise the pin 26 is prevented from engaging the notches 16, 22 by the corner formed between the radially inner edge of the slot 21, and the notch 22. Instead of providing the teeth 19, 20, the radius of the radially inner edge of the slot 15 may be made greater than the radius of the radially inner edge of the slot 21. The pin may be urged outwardly and the notches formed in the radially outer edge of the slot 15. Stays as described may be used in pairs for perambulator hoods, the hood being fully raised when the pin 26 is in the overcentre position, and half raised when the pin is in the locked position. In another embodiment, Fig. 9 (not shown), two locking positions are obtained by providing two notches in the slot 15. In a further embodiment Figs. 10, 11, 12 (not shown), the arcuate slot 15 of the arm 11 is replaced by two angled straight edges intersecting at the notch 16 and the portion of the disc radially outside the slot 15 is cut away.

A polymer matrix in the form of beads, which can be used for the production of ionexchange resins, is prepared by effecting suspension copolymerization of a neutral monomer of formula CH 2  = CRR<SP>1</SP>, where R is H, alkyl or cyanomethyl and R<SP>1</SP> is halogen, alkyl, cyanomethyl, substituted or unsubstituted aryl, nitrile or a heterocyclic group, with at least two cross-linking agents each of which has at least two olefinic bonds, at least one of said agents being an aliphatic or cycloaliphatic hydrocarbon or chlorohydrocarbon and the remainder being one or more aromatic hydrocarbons. The polymer matrix can be converted into an ion-exchange resin by treating the matrix beads with an appropriate reagent so as to introduce anion- or cation-exchange groups into the matrix, e.g. by hydrolysis of nitrile groups, chloromethylation and subsequent amination, or sulphonation. Suitable neutral monomers for the preparation of the matrix include styrene, acrylonitrile and methylene-glutaronitrile. Specified as (cycio)- aliphatic cross-linking agents are 1,3-butadiene, isoprene, piperylene, chloroprene, 2,3-dimethylbutadiene - 1,3, 2,3 - and 1,4 - pentadiene, 1,5 - and 2,4 - hexadiene, 2,5 - dimethyl - hexadiene-2,4, octadienes and methyl, dimethyl and methyl-methylene derivatives thereof, 1,3- decadiene, 1,3,5-hexatriene, hexachlorocyclopentadiene, cyclopentadiene and dicyclopentadiene. Aromatic cross-linking agents specified are divinyl- and trivinyl-benzene. In examples the suspension copolymerization is effected in the presence of benzoyl peroxide.

An instrument for the determination of the refraction of a light beam in its passage through the atmosphere in order to ascertain the correction to be applied during surveying comprises a transmitter and a distant receiver, the former transmitting a moving pattern of light bars in two ranges e.g. 2900 - 3000 A and 5800 - 6000 A displaced in phase by 90 degrees, and the latter comprising means for applying the two ranges to respective detectors, and comparing the phase of the respective outputs. Light from an arc lamp is modulated by spirals on a rotating disc reticle and the phase displacement of the two ranges is achieved by a prism. The received beam is split by a splitting mirror and the desired ranges are applied via filters to detectors which may be photo-multipliers. The output of a phase comparator to which the signals are applied is indicated on a meter. The beam may alternately be modulated by a linear moving fence type reticle.

Abstract: 685,275. Supersonic inspection devices. SPERRY PRODUCTS, Inc. Feb. 28, 1951 [March 2, 1950], No. 4845/51. Class 118 (ii). Relates to a'pulse echo system of the type disclosed in Specification 663,064 for detecting flaws in a thin plate 10 or pipe in which wave pulses are transmitted into the plate at an oblique angle and are propagated in the plate by multiple reflection, reflected pulses from a defect or the end of the plate being returned to the transducer by a similar multi-reflection path. In such a system a diffuse defect, e.g. a porous. region, does not produce a clearly defined echo since the pulses incident on the defect are merely scattered causing attenuation and according to the present invention such defects are detected by spacing a prism 40 from the transducer 16 in order to reflect the transmitted pulses, the amplitude of the reflected pulses as displayed on a cathode-ray tube 25 synchronized with the transmitter pulse generator 15 being reduced when a diffuse defect is present between the transducer and prism 40. As shown the transducer 16 is coupled to the plate 10 by a prism 17 and the angles # of the prisms 17 and 40 are preferably equal. The prism 40 may be adjustably connected to the transducer by a mechanical linkage, Fig. 4 (not shown).
