Title: Controllers for dc or Universal Electric Motors
IPC: H02P7/295
Filed: 1968-08-29
Abstract: 1,182,399. Control of D.C. motors. GENERAL SIGNAL CORP. 29 Aug., 1968 [8 Sept., 1967], No. 41290/68. Heading H2J. A D.C. or universal motor 11, 12 is operated to position a load, such as a flow-regulating valve. Motor 11 drives a positional feedback signal generator 45. When the control signal produced by generator 46 is different from the feedback signal, summation network 18 produces an error signal which is fed into operational amplifier 19 the output 25 of which is applied to a timing network 16 which operates diac 15 to fire triac 13. The direction of conduction of triac 13 depends on whether the feedback signal is above or below the control signal and determines the direction of current flow through motor field 12 and consequently the direction of rotation of the motor. Operational amplifier 19 may be replaced by a linear amplifier. Diodes 41b and 41c of rectifier bridge 74 may be replaced by voltage dropping resistors. Zener diodes 42 and 43 may be replaced by voltage dropping resistors and a single Zener diode connected across the bridge output sections 38 and 39. Diac 15 may be replaced by other static triggering means such as the silicon bi-directional switch. Triac 13 can be replaced by a pair of silicon controlled rectifiers gated from a pulse transformer, Fig. 2 (not shown). In a further modification. Fig. 3 (not shown) a step-down transformer reduces the voltage applied to the control section and a companion transformer couples diac 15 with the gate circuit of triac 13 to eliminate all D.C. paths between the control section and power lines L 1  and L 2  to prevent ground loops. This isolation scheme can be used in the silicon controlled rectifiers power switching device of Fig. 2 by adding a step-down transformer and reconnecting the pulse transformer as in Fig. 4 (not shown). Specifications 1,178,348 and 1,106,800 are referred to.

Title: Process for improving the adhesive properties of polyolefines
IPC: B29C59/16
Filed: 1958-12-24
Abstract: A process for treating the surfaces of polyolefines to improve the adhesiveness thereof for macromolecular film-forming materials, comprises subjecting the polyolefin in a non-particulate form (e.g. as foil) to the action of a mixture of gaseous chlorine and gaseous sulphur dioxide in the presence of activating irradiation, for a time short enough for only the surface of the polyolefin to be affected by the sulpho-chlorination, the polyolefine as a whole remaining unchanged.  In examples the time ranges from 1 to 30 minutes.  The polyolefines may be polyethylene, polypropylene, ethylene propylene copolymers, polybutylene and polymers or copolymers of olefines having 5 or more carbon atoms.  The irradiation may be effected with quartz lamps (mercury lamps), incandescent lamps of high power (e.g. 1,000 watts), arc lamps or with ultraviolet light.  Following the chlorosulphonation the surface of the polymer may be aired to remove residual gases and may be coated or printed, e.g. with a paint, a lacquer or an adhesive film (see Examples 2, 3, 4, 5 and 6).  Foils of low pressure polyolefines such as polyethylene which have been biaxially orientated may be bonded following treatment by the process of the invention (see Examples 1, 7, 8, 9 and 10).  Macromolecular film-forming substances which may be used are chlorinated polyethylene, sulphochlorinated polyethylene, polyvinyl acetate, polyvinyl alcohol, polyvinyl chloride, polyvinyl chloracetate, polyvinyl propionate, polyesters, polyamides, natural rubber, copolymers of butadiene with acrylonitrile or styrene, neoprene, polyacrylic acid or esters, polyacrylonitrile, silicones, polystyrene, alkyd resins, epoxy resins, copolymers of vinyl chloride with vinyl esters or ethers or with acrylic monomers, cyclohexanone resins (with/without plasticizer) and melamine resins.  In examples the printing lacquers used comprise ingredients selected from benzene, cyclohexanone, methoxybutyl acetate, polyvinyl chloride, PV Fast Yellow, dibutyl phthalate, dioctyl phthalate and polypropylene. In Example 9 the sulphochlorination is applied to polypropylene sheet containing carbon black.  Specifications 799,392, 799,823, 801,031 and 819,867 are referred to.

Title: Shared volume and tone control system
IPC: H03G9/00
Filed: 1972-09-15
Abstract: 1354214 Gain and tone control MOTOROLA Inc 15 Sept 1972 [8 Oet 1971] 42941/72 Headings H4R H3Q and H3W A plurality of amplifiers have a common tone control and a common gain control, which controls are interconnected by a unidirectional conducting device in such a manner that variation of the tone control over part of its range causes a variation in the gain of the amplifiers. Gain control is effected by adjustment of a volume potentiometer 16 of which the tapping point 24 is connected to each amplifier, a fixed tapping point 23 of the volume potentiometer being coupled via diode 22 to the variable tapping point 26 of the tone control potentiometer 18. For a fixed volume potentiometer setting tone control is effected as follows. With tapping point 26 at earth potential diodes 46, 48, 50 are off, diode 22 is conducting and the frequency response of each amplifier is flat. As the potential at point 26 is increased diodes 46-50 turn on gradually whilst diode 22 is gradually turned off, all diodes operating in their non linear resistance range. The circuits comprising capacitors 40-44 and diodes 46-50 act to gradually shunt high frequency signals to earth but as the gradual turning off of diode 22 increases the potential at tapping point 24, the amplifier gains are increased to maintain the volume levels of the high frequencies at the amplifier outputs thereby effectively providing a bass boost. It is arranged that diode 22 turns off completely before diodes 46-50 are turned fully on and hence after a certain position of the tone control the bass frequency volume is no longer being increased but the high frequencies are still being further attenuated. Hence a response which is bass boosted and has a treble cut off is produced.
