Filed: 1964-11-30
Abstract: Sized glass fibre products are desized and softened by treatment with acid so that the extraction rate is 5-25% based on the weight of glass fibres having no size content before treatment.  The acid which may be inorganic, e.g. HCl, H2SO4, or HNO3, or organic, e.g. CH3COOH or (COOH)2, may contain a metal, other than an alkali metal, whose atomic number \sF12, or a salt of such a metal.  The products may subsequently be coloured by treatment with an aqueous solution of a coloured metal salt.  They may then be subjected to thermal treatment at 600 DEG  C. and/or treatment with resin.ALSO:Sized glass fibre products are desized and softened by treatment with acid so that the extraction rate is 5-25% based on the weight of glass fibres having no size content before treatment.

Abstract: 1434252 Clavichords E N DODSON 9 Jan 1975 [18 Oct 1973] 48635/73 Heading G5J A double strung fretted clavichord has tangents arranged so that when one has struck the strings, operation of the second excites one string leaving the other vibrating in its original mode. Preferably the tangents L, K have stepped surfaces P, O, the raised parts of the surfaces being offset to the left along the string to compensate for the increased tension applied by these parts. The striking surfaces of the tangents may be concave, various forms of tangent being described, Figs. 3 and 4 (not shown). If one string is higher than the other one tangent may be level and the other stepped. Where three tangents are to share two strings, two stepped tangents are provided on either side of a level tangent to permit any two of the three notes to sound simultaneously.

Abstract: 1,244,496. Windscreen wipers. McCORD CORP. Oct.28, 1968, No. 51108/68. Heading A4F. [Also in Division H2] In a windscreen wiper system in which a wiper is driven intermittently by an electric motor a housing 34 rotatably supports the wiper spindle 25 on which are rotatably mounted cams 41, 42 selectively engageable with the actuating member 73 of a switch 32 to open and close the wiper motor circuit, and a lost motion device connects the driving mechanism coupling the motor with the spindle 25, the cams 41, 42 being disengaged from the actuating member 73 for a predetermined time period during which a member 47 of a time delay device is spring actuated to rotate the cam 41 to close the switch 32 at the end of the time period, when the wiper motor is energized to rotate the cams 41, 42 and move the member 47 in the opposite direction. The time delay device 31 is pneumatically controlled and the member 47 is a rod connected to a piston 49 Fig.3 (not shown) movable in a housing 56 to which air is admitted via a bleed tube 55 which is pinched to control the air flow therethrough. The circuit for controlling the wiper motor 18, Fig. 5, and a motor 117 driving a windscreen washer pump, comprises a manually controlled multiple switch 30 including switches 94, 96, 97 having rotatable switch arms 94a, 96a, 97a, and 98a respectively, simultaneously movable to three positions for (a) wiper parking (b) continuous or intermittent wiping operation, and (c) windscreen washer operation with continuous or intermittent wiping operation. When the switches 94, 96, and 97 are in their wiper parking positions the circuit through said switches and the motor 18 is opened at the parking switch 113. When the switches 94, 96 and 97 are moved to their wiper operating positions as shown in Fig. 5 the circuits of motor field coils 105, 107 are completed via switches 101, 102, respectively. With the switch arms 101a, 102a maintained in engagement with the resistance 101c and bridge terminal 102b respectively, the wiper motor 18 will run continuously at a speed controlled by the setting of the arm 101a and the resistance 101c. To operate the wiper motor 18 intermittently the switch arm 102a is set to engage terminal 102c so that the circuit through the field coil 107 is completed through the switch 32 controlled by relative rotation of the cams 41, 42. To operate the washer pump during either intermittent or continuous wiper operation the switch members 94a, 96a 97a, and 98a are moved to the dotted line positions shown in Fig. 5 to operate the motor 117 without affecting the wiper operation.

In an automatic pilot, signals from magnetometers responsive to horizontal components of the earth's magnetic field are applied through feedback amplifiers to control a rudder motor, positional feedback signals from which vary the magnetic field in the vicinity of the magnetometers. In Fig. 6 (not shown), a pair of flux gate magnetometers 31, 32 are pivoted to remain in a horizontal position on a ship and adjusted so that they will point in an E-W direction when the ship is heading in a desired direction. The magnetometers are energized intermittently by an oscillator 44 and their outputs are separately rectified by diodes 55, 55' and amplified by transistors 53, 61 when heading deviation is sufficient to produce signals large enough to overcome the bias applied by a threshold circuit 47. Feedback is applied to the magnetometer windings through resistors 57, 64 and, since the windings are opposed, this results in one feedback being positive and the other negative to cause one or other of two relays 56, 65 to operate according to the sense of deviation so that a rudder servomotor 50 is operated in the appropriate direction to correct the deviation. A potentiometer 51b, operated with the rudder, provides negative feedback for application to auxiliary windings 52a, 58a associated with the magnetometers to make rudder deflection proportional to heading deviation. A variable resistance may be included in the last-mentioned feedback circuit to enable the amount of feedback to be adjusted to suit the response of the system.
