Title: Improvements relating to electric distant control systems
IPC: G08C19/38
Filed: 1926-10-20
Abstract: 260,579. Granat, E., and Compagnie des Forges et AciÚries de la Marine et d'HomÚcourt. Oct. 31, 1925, [Convention date]. Addition to 240,151, [Class 38 (iii), Electric motor control systems &c.]. Electric transformers; phase, changing. - A transmitter for an electric distant control system comprises a stationary inductive-winding connected to the segments of a commutator with which co-operates a set of movable brushes connected to the transmission wires. As shown in Fig. 1, the transmitter comprises a set of brushes 7, 8, 9 rotatable by a hand wheel 17 and co-operating with the commutator 2 connected to a winding 1 evenly distributed around a magnetic yoke 3. The winding 1 is supplied from polyphase mains. Displacement of the brushes adjusts the phase of the currents in the transmission wires to cause the operation of a receiver motor into a repeating position. Fig. 3 shows a modification wherein two sets of brushes 40, 41, 42 and 45, 46, 47 are independently rotatable on the commutator 39 by hand-wheels 44, 49. The winding is supplied through the brushes 40, 41, 42 and the brushes 45, 46, 47 are connected to the transmission wires. There the phase of the currents in the transmission wires may be adjusted by each set of brushes. In a further modification the single winding may be replaced by two windings which act as a two winding transformer. Specification 259,187 is referred to. The Specification as open to inspection under Sect. 91 (3) (a) states that the control system may be supplied with single phase current. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to the production of road surfacing binders
Inventor: DEMEESTER JACQUES
IPC: C10C3/04
Filed: 1965-06-23
Abstract: A road surfacing binder is made by blowing with air at elevated temperature (150 DEG  to 350 DEG  C.) a blend of: (a) 90 to 95 parts by weight of a vacuum residue having a cut-point of 550 DEG  to 570 DEG  C. and derived from a Middle East crude, and (b) 10 to 5 parts by weight of a heavy coal tar oil.  The invention increases the adhesivity of the binder, relative to the residue, for a given penetration, which lies in the range 10 to 350 mm./10 at 25 DEG  C. The coal tar oil is a coal tar distillate sufficiently involatile to cause no fire risk during blowing and in an example was obtained by distillation at atmospheric pressure in a plate column and had a cut-point of 370 DEG C.  Its density, viscosity, flash point etc. are given.  Two blends incorporating 10 parts b.w. of this oil with 90 parts b.w. Kuwait vacuum residue (Specification given) are described, the blends being blown to different terminal values of the penetration (namely 210 mm./10 at 25 DEG  C. and 98 mm./10 at 25 DEG C.), the specifications of the two binders being given.  A catalyst may be used in the blowing.

Title: Improvement in the production of fibres of acrylonitrile polymers
IPC: D01F6/18
Filed: 1960-07-29
Abstract: 954,553. Treating polyacrylonitrile. CRYLOR. July 29, 1960 [July 30, 1959], No. 26571/60. Heading B5B. Undrawn filament of acrylonitrile polymer are subjected at least once between their consolidation and final drawing to the action of a liquid consisting of or comprising as the major component, an aliphatic ketone. Acrylonitrile polymers are defined as acrylonitrile homopolymer, or copolymers and grafted polymers containing at least 85% of acrylonitrile and mixtures of such polymers. Undrawn filaments are defined as monofilaments, yarns or tows made by wet or dry spinning before they have undergone their complete drawing. They may have undergone washing or a preliminary drawing. Filaments are said to be consolidated when as a result of any spinning process, they have set to such an extent that their mechanical strength is sufficient to withstand normal textile treatments, e.g. winding-up. The filaments may be immersed in an aliphatic ketone, e.g. acetone, methyl ethyl ketone or diethyl ketone, before or after elimination of spinning solvent. The treatment may comprise removal of solvent by washing with a ketone. The treatment may be continuous or discontinuous, e.g. a wound package of filaments may be immersed in a ketone bath or yarn may be continuously passed therethrough. The ketone bath, or the last bath if several are used, preferably contains an oiling-agent, e.g. butyl stearate. Preferably, the treatment is carried out as closely as possible to the final drawing stage. In an example, a polyacrylonitrile yarn obtained by dry spinning is washed with water to remove solvent, collected in a perforated pot, and successively immersed in two baths comprising 70% acetone and 30% water. The yarn thus treated has improved drawing properties.

Title: Proximity sensing device
IPC: B66B13/26
Filed: 1966-06-15
Abstract: 1,111,735. Proximity switches. DOVER CORPORATION (CANADA) Ltd. June 15, 1966 [June 28, 1965], No.26602/66. Heading G1N. A proximity switching arrangement such as a "touch switch" for a lift system comprises a stable (i. e. fixed frequency) oscillator loosely coupled to a resonant receiver having a capacitance sensor plate, whereby the proximity of a conductive body detunes the receiver and thus reduces its output to operate a relay. As shown transistor T1 is connected in a Colpitts oscillator circuit having its tank-circuit loosely coupled to a resonant receiver circuit L2, C6, including a sensor plate SP. The output is rectified at D1 and applied through an opposing Zener diode D2 to a transistor T2 which is biased to the ON-condition in the absence of an input signal to hold transistor T3 switched OFF. In operation, the coupling between L1, L2 is adjusted to provide sufficient output to switch T2 OFF, so that when the circuit is detuned by the proximity sensor, T2 switches on and cuts off T3, and the collector voltage rises to operate relay XL.

The cone halves may normally be held apart either by springs or by projections L<2> on the lower pair of upper and lower rope-guides L, L<1> secured to the pillars E. Actuation of the frame when the cage rests on props &c. is prevented by the simultaneous resting on the props of a bar Q cross-connecting side levers P pivoted at P<2> and connected to the frameby links P<1>. The guide-ropes C are passed round. upper pulleys M and a lower weighted pulley. The upper pulleys gear with a brake wheel N. Thebrake N' is initially adjustable, and is further applied, upon movement of the guide-ropes, by a screw O rotated by means of a worm-wheel R' driven by the pulleys M through gearing and a worm R.

Title: Aperture corrector for television signals
IPC: H04N5/208
Filed: 1973-06-07
Abstract: 1420257 Television PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 7 June 1973 [10 June 1972] 27172/73 Heading H4F A conventional aperture correction signal derived at 18 from a television video signal at input 3 with the aid of line period delays 6 and 7 and image element period delays 11, 13 and 14, is modified in an amplifier 2 before it is added 40 to the video signal (delayed by 6 and 13) and the resultant gamma corrected 42, the amplifier 2 having different amplification factors for the positive and negative signal values in the correction signal so that an attenuated correction signal is derived in black level regions of the video signal and an amplified correction signal in peak-white value regions. Amplifier 2 prevents the disturbing broadening, i.e. emphasis, of image contours which would otherwise occur in the black area of the displayed aperture corrected video signal. Amplifier 2 includes an operational amplifier 20, the positive signals of the aperture correction signal (e.g. the horizontal aperture correction signal C H ) being applied to one signal channel (20, 21, 23, 25) and the negative signals to a second channel (20, 22, 24, 27). As shown these negative signals C HB  are derived from the video signals located nearest the black level and are amplified as a function of the instantaneous value of the video signal P, i.e. in response to a control signal P c  derived from signal P via 33-38 and applied to the insulated gate electrode of FET 27 so that a varying amplification factor A B  occurs in the second channel. FET 27 may be replaced by a resistor which might or might not be adjustable. Operational amplifier 28 constitutes a signal adder circuit which with potentiometer 26 allows the peak-to-peak value of the modified aperture correction signal to be adjusted. The black level of the input video signal is fixed at ground potential by periodically active clamping circuit 4. In a colour television camera the aperture (contour) correction signal is only derived from the green chrominance signal and added to all three chrominance signals. The aperture correction signal generator may include a one field period delay storage tube.
