Abstract: 208,719. Thedinga, E. Dec. 21, 1922, [Convention date]. Void [Published under Sect. 91 of the Act]. Binding-posts and terminals; plug connectors.-A wire is gripped between two contact parts adapted to be screwed together upon a common axis, each having a guide for the conductor such that upon relative rotation one wire is drawn from the guide in one of them, bent around the common axis and finally clamped between the parts. The Figure shows a two-pin plug with a contact part f, provided with a hole h and a screwed stem g, fixed in a recess in the plug body a. The plug pin b carries the second contact part c and is adapted to engage the stem g. A hole or recess d in the part c is aligned with the hole h and after induction of a conductor and turning the contact part c upon the screw the conductor will be coiled around the screw and eventually clamped between the parts c and f. Two pairs of aligned holes may be arranged to connect two conductors together between the contact parts.

Title: Improvements in and relating to the production of urea derivatives
IPC: C07C273/18
Filed: 1922-11-23
Abstract: In the production of tetrasubstituted ureas by the interaction of carbonyl chloride with a secondary amine in a solvent, an agent, such as a tertiary amine, is added to fix the hydrochloric acid liberated. According to the example, a mixture of monomethylaniline and dimethylaniline, such as results for example from the methylation of aniline, is dissolved in benzene and carbonyl chloride passed into the heated solution; after the benzene has been distilled off, the excess of dimethylaniline, which formed the acid-fixing agent, is removed by adding dilute hydrochloric acid and the dimethyldiphenylurea filtered off.

Title: Improvements in the manufacture of textile articles containing or consisting of fibres of a cellulose triester set in a three-dimensional form
Inventor: FINLAYSON DONALD
IPC: D06M23/14
Filed: 1954-11-09
Abstract: Textile articles containing or consisting of fibres of a cellulose triester of a fatty acid having 2-4 carbon atoms in the molecule, the fibres being of a normal degree of crystallinity, are treated, while held in a three-dimensional form, to increase substantially the crystallinity of the triester and to set the articles so that, while they can be deformed by the action of stress, they tend to resume their original form when the stress is removed.  The articles are preferably treated, while held on a former in a fixed position to resist shrinkage, with steam or hot water at about 120-160 DEG  C., and especially with steam at about 15-75 p.s.i. gauge pressure.  They may also be subjected to dry heat at about 175-245 DEG  C., e.g. as described in Specification 758,442, or to the action of an organic liquid which is a swelling agent for cellulose triacetate, e.g. as described in Specification 776,346.  The article may be a three-dimensional article of woven, non-woven or knitted fabric or a single thread of fairly high denier coiled in the form of a spring. It may contain up to 70 per cent of fibres other than cellulose triesters, e.g. acetone-soluble cellulose acetate or natural or regenerated cellulose.  The cellulose triester fibres are preferably produced by melt-spinning, especially as described in Specifications 719,853, 719,860, 721,674, 726,900, 731,930, 748,772, 761,158 and 763,489, but may also be produced by wet-spinning, e.g. as described in Specification 687,414, or by dryspinning.  They may also be obtained by the further acetylation of a textile material comprising unoriented yarns of cellulose acetate of a lower acetyl value, e.g. as described in Specifications 448,816, 448,817 and 448,917, [all in Group IV].  In an example, knitted garments of melt spun cellulose triacetate yarn are thoroughly wetted with cold water, placed on a former of the desired shape and steamed for about one minute at a pressure of 40 p.s.i.g. Specification 753,461 also is referred to.

Title: Automatic-chrominance-control system
IPC: H04N9/68
Filed: 1957-10-17
Abstract: 816,666. Automatic phase-control systems. HAZELTINE CORPORATION. Oct. 17, 1957  [Nov. 16, 1956], No. 32470/57. Class 38 (4). [Also in Groups XL (b) and XL (c)] Relates to an automatic-gain-control system for the chrominance channel of a colour television receiver operating with the N.T.S.C. type of signal. In accordance with the invention the gain control detector 40 is a phase detector which compares the synchronizing burst obtained from the chrominance channel 20 via a gated amplifier 26 with the in-phase component of the local sub-carrier reference signal which is applied via lead 49. When the receiver is operating correctly with the reference signal in synchronism with the received bursts, the detector functions to produce a D.C. potential at point 50 which is proportional to the amplitude of the bursts. This potential constitutes the gain control potential and is applied via lowpass filter 52 and lead 55 to control the gain of channel 20 to stabilize the level of colour signals in the conventional manner. When, however, the receiver fails to operate in synchronism with the burst, the potential produced at point 50 is an alternating potential at the difference frequency between the burst and reference signals. In this condition no potential appear through filter 52 on lead 55 and the colour channel operates at maximum gain. Synchronizing bursts of increased amplitude are thus produced and permit the automatic-phasecontrol system 28-30 for the reference oscillator 31 to re-establish synchronism rapidly. The gain control potential may also be applied to control filters 29 and buffer amplifier 32 to further increase the sensitivity of the automaticphase-control system when the receiver goes out of synchronism. Reference is made to the use of the output from detector 40 to control a colour-killer circuit to disable the chrominance channel when other than a colour signal is received.

[Class 37] [Also in Groups XL and XI] In a radio receiver combined with a pedestal lamp, parts of the receiving apparatus are housed in the base section and other parts in the shade, the control of an adjustable element in one of the sections being manually effected by a member mounted on the lamp stanchion and rotating about the axis of the stanchion. In the embodiment of Fig. 1 the lamp comprises a shade 150, base 151 and supporting stanchion 152. The receiver is of the superheterodyne type, the combined volume control and switch 153 and the power supply unit 154 being housed in the shade assembly together with the illuminating lamps. The remainder of the receiver including the tuning condensers 155 are housed in the lamp base. The volume control and switch 153 are actuated through gearing by rotation of tube 210 and operating ring 211. The condensers 155 are similarly adjusted by rotation of ring 174 which rotates tube 158 through a train of friction discs for vernier adjustment. Adjustment of tone may also be provided and may replace the volume control in the lamp shade, the latter control then being housed in the base (Fig. 5, not shown). Other modifications relate to gearing for controlling the variable condensers which may comprise planetary systems, Figs. 7 and 8 (not shown), or bevel gears, Figs. 9 and 10 (not shown). The Specification as open to inspection under Sect. 91 also describes other forms of construction which now form the subject-matter of Specification 512,141. In a further embodiment, Figs. 11-15 (Cancelled, not shown), the lamp shade unit is detachable from the stanchion, connections being effected by plug-andsocket members. This subject-matter does not appear in the Specification as accepted.

Abstract: 1,134,460. Filling moulds FORMWOOD Ltd. 17 July, 1967 [29 July, 1966], No. 32698/67. Heading B5A. A method of filling a mould with a mixture of comminuted organic fibrous material and a binder, comprises blowing the moulding material from a predetermined position by means of an air current so that the material is first deposited in the mould cavity furthest from the filling nozzle and progressively accumulates towards the filling position until the mould is full.
