Title: A process for improving the stability of polyolefines
IPC: C08J3/28
Filed: 1965-01-25
Abstract: The stability of a polyolefin is improved by dispersing the purified polyolefin powder in an inert hydrocarbon or aliphatic alcohol, admixing with 0.1 to 1% of a tertiary organic hypochlorite or a secondary organic hypochlorite containing an aromatic radical, heating under the action of ultra-violet rays, separating, and then washing the polyolefin.  In examples, the hypochlorite used is t-butyl hypochlorite, and heptane, isooctane or methanol is the medium. The treated polyolefins are tested for stability in compositions containing dilauryl thiodipropionate and thio-bis-(3-Me-6-t-Bu-phenol).

[Also in Divisions B3 and B4] A bolt-hole, nut &c. bush 10 comprises a thin-walled body with internal and external threads and means for locking the bush in the bolt-hole &c. The external threads 14 have shallow roots 15 and at least one of the internal threads 16 is removed by a counterbore 20 which facilitates expansion of the neck of the bush into locking engagement with the bolthole. This may be counterbored at 44, and the top thread or threads of the steel, stainlesssteel or aluminium alloy bush may be formed with teeth 34 of larger diameter than the threads 14. Grooves 30 in the threads 16 receive the hexagonal driving end of a tool 66 (see Divisions B3 and B4) which has an enlargement 70 drivable into the counterbore 20 for expanding the neck. The bolt-hole threads 38 also are of shallow form. One or more of the threads 16 may be deformed inwardly and slightly axially to form locking threads.

Alternatively, a four-cornered driving recess may be formed with corners 144, Fig. 14 (not shown), at about 120 degrees. The bush may taper, Fig. 16 (not shown), or have a locking neck at each end for engaging a nut 162, Fig. 17. The bush may be made self-tapping by tapering the end threads 274, Fig. 27, and forming recesses 272, radial openings, Fig. 29 (not shown), or axial slots, Fig. 33 (not shown). If the recesses 272 &c. are omitted, the metal of the bolt-hole may be displaced by the bush to form screw-threads.

Patent GB-575073-A (GB)
Title: Improvements in or relating to the production of cellulose ethers and of articles made therefrom
IPC: C08K5/17
Filed: 1944-02-25
Abstract: Cellulose ethers are stabilized by incorporating therein a N-alkylated diamine, which preferably contains at least two alkyl radicles attached to the nitrogen atoms.  N.N.diethyl ethylene diamine, tetra-ethyl p-phenylene diamine, tetra-methyl ethylene diamine, tetraethyl ethylene diamine, the butyl ethylene diamines, the ethyl and butyl hexamethylene diamines, the di-ethyl and di-butyl p-phenylene diamines and the tetra-ethyl and tetra-butyl p-phenylene diamines are specified.  The incorporation of the stabilizing agent may be effected before separation of the ether from the etherification solution or subsequently, for example, it may be dissolved, and added to the cellulose ether in solid form or in solution.  The stabilizing agent may be dissolved in an organic liquid which has a swelling action on the ether.  The cellulose ether and the stabilizing agent may be dissolved and the solution formed employed for the manufacture of artificial filaments, foils and the like, or as a coating composition.  The amount of stabilizer employed is from 0.05 per cent of stabilizer or 0.01 per cent of basic nitrogen, up to 1 per cent of stabilizer or 0.2 per cent of basic nitrogen, but is usually from 0.05 to 0.5 per cent of stabilizer or 0.01 to 0.1 per cent of basic nitrogen.  In order to reduce oxidation of the alkylated diamines, some of which yield coloured compounds, it is preferred to use neutral or slightly acid aqueous media.  Examples are given of the stabilization of ethyl cellulose by means of N.N.diethyl ethylene diamine.  According to the Provisional Specification, other basic substances may be employed in place of the N.alkylated diamines, particularly aliphatic and alicyclic bases, for example, 1-amino-heptane, 1-amino-octane and their higher homologues, 1-amino-2-methyl octane, 2-amino-2 : 7-dimethyl octane, cyclo-hexylamine and 3-methyl cyclo-hexylamine, 1 : 4-diamino-butane, 1 : 4-diamino-2-methyl butane, 1 : 6-diamino-hexane, 1 : 2-diamino-cyclo-hexane, and aromatic compounds such as benzylamine and diethylbenzylamine.

Title: Improvements in or relating to a protecting circuit for an electrolytic machining system
IPC: H02H7/125
Filed: 1966-01-27
Abstract: 1,143,932. Electrolytic machining. ATELIERS DES CHARMILLES S.A. Jan. 27, 1966 [March 4, 1965], No.3651/66. Heading C7B. [Also in Division H2] A protective circuit for an electrolytic machining apparatus including an electrolyte-filled gap between a tool electrode and a workpiece comprises a high pass filter operatively connected to the gap, the filter passing currents produced by an incipient fault in the gap; a detecting and discriminating device connected to the output of the filter, the device comprising means for discriminating between persistent signals produced by the incipient fault and transient parasitic signals of shorter duration than the fault signals, and further means for operating a cut-out for the current supply to the machining apparatus on detection of persistent signals produced by the incipient fault. As described the machining current is obtained from a rectified three-phase A.C. supply and detection of persistent incipient fault signals de-energizes a transistor (Q 1 ) which causes via a transistor circuit a relay to operate a solenoid-controlled switch in the A. C. power supply to shut down the apparatus. In one embodiment Fig. 1 (not shown) a control circuit for each phase of the supply is arranged to energize a further transistor (Q c ) bridging the first-mentioned transistor Q 1  to prevent this causing shut down due to transient high frequency parasitics in the current fed to the machining gap produced by rectifier switching in the absence of incipient fault signals, these if present being effective in those parts of the A. C. cycle when parasitics have ceased and the phase-dependent control circuits do not energize the bridging transistor Q 0 . In a second embodiment Fig.2 (not shown), incipient fault signals and parasitics passed by the filter de-energize the transistor Q 1  and in consequence the voltage applied to the base of a second transistor (Q 2 ) gradually approaches that of the negative terminal of a subsidiary supply as a condenser (C 1 ) in series with a resistor network across this supply becomes charged. If the filter output de-energizing the transistor Q 1  are of sufficient duration, i.e. are not transient parasitics, transistor Q 2  is also de-energized to effect shut-down of the apparatus.

Abstract: 1,271,155. Transistors. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 23 April, 1969 [23 April, 1968], No. 3691/71. Divided out of 1,271,154. Heading H1K. In a planar transistor, which may form part of the integrated capacitor memory described in Specification 1,271,154, from which the present application is divided, the capacitance of or in parallel with the collector junction is increased by provision of an additional region adjoining the base region. This region is directly connected to one of the base and collector regions and forms a PN junction with a part of the other region sandwiched between it and the one region. In Fig. 4, the region, 53, is formed in the same diffusion as the emitter region and overlies a thicker part 51a of the base region extending down to a low resistivity inclusion 4a forming part of the collector. In a modification the inclusion is absent and the base region of uniform thickness. One or more inclusions of the same type as region 53 may be formed in the surface of the base region and connected by conductive tracks to region 53. Finally in the lateral transistor shown in Fig. 6 with a frame-shaped collector and central emitter 83, the additional region 92, of the same conductivity type as the base is channel-shaped and overlaps the collector almost completely except on the side at which the collector electrode is attached. The surface passivation may be silicon nitride and/or oxide and in Fig. 6 the epitaxial base layer has a heavily doped lower section 103. The proximity of the additional part of the collector to the surface is advantageous where the photosensitivity of the collector junction is to be used.
