Title: Resins derived from phenol-formaldehyde condensates and epichlorohydrin
Inventor: HANSON NORMAN WILLIAM
IPC: C08G59/08
Filed: 1952-08-01
Abstract: An epoxy resin is made by reacting epichlorhydrin in the presence of an alkali with a partially oxyalkylated derivative of a nonheat-hardenable phenol-formaldehyde condensation product, the oxyalkylated derivative containing an average of at least 1.0 but less than 3.0 phenolic hydroxyl groups and an average of from 3-8 benzene nuclei per molecule.  The products are useful as resins and plasticizers and may be esterified with unsaturated drying oil acids to yield esters, preferably of molecular weight 1000-3000, having film-forming properties.  Oxyalkylation may be effected by an alkylene oxide (e.g. ethylene or propylene oxide) or a 1-chloro-2-hydroxy alkane.  In examples: (1)-(3) a cresol-formaldehyde resin having an average of 4 benzene nuclei and 4 phenolic hydroxyl groups was reacted with propylene oxide to convert 2 of the phenolic groups into alcoholic hydroxyl groups. The resultant phenol alcohol was then heated with epichlorhydrin first alone and then in presence of sodium hydroxide; a resin was extracted from the mixture by butyl acetate, a mixture of butanol and xylene or methyl cyclohexanol.  (4) A cresol-formaldehyde resin having an average of 4 benzene nuclei and 4 phenolic nuclei was treated with propylene oxide to convert 3 phenolic groups into alcoholic hydroxyl groups; the phenol alcohol was reacted with epichlorhydrin as in (1). (5) A pxylenol-formaldehyde resin having an average of 4 benzene nuclei and 4 phenolic hydroxyl groups per molecule was reacted with propylene oxide to convert 2 of the phenolic groups into alcoholic hydroxyl groups; the phenol alcohol was reacted with epichlorhydrin as in (1).  (6)-(10) The products of examples (1), (2), (4) and (5) were heated at 230-235 DEG  C. in an atmosphere of CO2 with groundnut fatty acids, linseed oil fatty acids or whale oil fatty acids.  The resulting resinous esters when dissolved in xylol or a mixture of butanol and xylene and, if desired, containing metallic driers, are coating compositions.

Title: Constrictor device for fitting tubeless tyres
Inventor: DAW REGINALD FRANK
IPC: B60C25/14
Filed: 1958-06-20
Abstract: 915,551. Inflating tubeless tyres. DUNLOP RUBBER CO. Ltd. June 5, 1959 [June 20, 1958], No. 19756/58. Classes 144 (1) and 144 (2). A device for constricting a tubeless tyre, to spread the tyre beads on to their rim seats for inflation, comprises one or more flexible chains 1 connected into a band encircling the tyre crown by one or more connecting assemblies 2, 3, each of which includes a radially adjustable tyre-engaging thrust member 7-10, whereby local pressure may be exerted on the tyre crown, the consequential reaction acting through the chain or chains 1 to constrict the tyre around at least a major portion of its periphery. As shown, two chains 1 are connected together at diametrically-opposed positions by two connecting assemblies, each comprising a yoke 2 having pivoted chainconnecting arms 3 and journalling a screwthreaded rod 7. The rod 7 is axially anchored in the yoke and co-operates with a screwthreaded sleeve 8 on a presser plate 9, the free end 10 of the rod being squared for spanner operation. For ready adjustment according to tyre diameter the chains 1 are engaged in keyhole slots 5 in each arm 3, as shown in Fig. 2. For small tyres only one chain, connected by a single connecting assembly, is necessary, the arms 3 of the assembly being shorter than those shown in Fig. 1. For very heavy tyres in situ on a jacked-up vehicle, the device of Fig. 1 may be assembled with the connecting assemblies each disposed above a horizontal diameter, the vehicle then being lowered just sufficiently to place the weight of the tyre on the ground and thereby provide a third pressure point symmetrically spaced with respect to the two connecting assemblies. For quick release prior to full inflation of the tyre, the chain 1, or the connection of the chain 1 to the associated arm 3, may include an over-centre toggle linkage 14-17, Fig. 4, operable by a detachable lever 20 to release the tension of the constrictor. The link 14 of the linkage has a hook 22 for readily detachable engagement with the chain 1.

IPC: H03K7/06
Filed: 1963-05-17
Abstract: 1,078,515. Pulse generating and pulse modulation circuits. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. April 20, 1964 [May 17, 1963], No. 19791/63. Headings H3T and H4L. In a circuit for generating pulses the repetition rate of which is dependent on the magnitude of an input signal, the input signal is integrated and arranged to trigger a monostable circuit when the integrated voltage reaches a predetermined value, the output of the monostable circuit being fed back to the integrator so that each pulse removes a constant amount of charge from the integrating capacitor. As shown in Fig. 2, D.C. signals are applied via terminals I1 or I2 to a Miller integrator comprising transistors T1 . . . T3 and capacitor C1 which produces a ramp the slope of which is dependent on the magnitude of the input signal. Zener diode Z1 breaks down when the integrated voltage reaches a predetermined value, triggering a monostable circuit comprising transistors T4 . . . T6, which generates a pulse the amplitude of which is limited by transistor T7 and Zener diodes Z2, Z3. Each pulse is fed back via a diode D6 to the input of the integrator so as to remove sufficient charge from capacitor C1 so that, after a time depending on the magnitude of the input signal at I1 or I2 the monostable circuit 3 is again triggered. The frequency of output pulses at terminals 01, 02 is thus indicative of the magnitude of the input signal at I1 or I2 and may vary linearly between 0 and 25 kc/s. for an input range of 0-6À8 v.
