Patent GB-2034129-A (GB)
Title: Two speed motor assembly
IPC: G10K11/18
Filed: 1979-09-28
Abstract: A motor unit for driving a rotational acoustic diffuser system comprises two electric motors. The shaft of the first motor carries a take off pulley and a friction wheel, the pulley providing a drive for the acoustic apparatus. The shaft of the second motor can be engaged with the friction wheel to drive the shaft of the first motor when the latter is de- energised. The first motor alone rotates the pulley at about 300 rpm while the second motor rotates the pulley, via the friction wheel and the shaft of the first motor, at about 30 to 40 rpm. The invention provides for the second motor to be mounted on a rotatable support plate which can be rotated to engage or disengage the circumferential surface of the motor shaft with the rim of the friction wheel. Preferably, the support plate is moved to the engaged position by an electromagnetic arrangement to be energised simultaneously with energisation of the second motor and de-energisation of the first motor. <IMAGE>
Patent GB-2119003-A (GB)
Title: Vehicle door latch
Inventor: WHITTAKER ERIC
IPC: E05C3/24
Filed: 1979-12-18
Abstract: Latch bolt 3 is pivoted at 4 to a lever 12 which is itself pivotally attached to the back and front plates 1, 2 of the latch casing. An actuator spring 14 is anchored at one end 15 to the casing and attached at the other end to a cranked linkage 16 which is held by a peg 6 projecting eccentrically from the bolt pivot 4. Closing the door introduces a striker pin 32 which firstly acts on cam surface 8 to lift bolt 3 and so to pass behind the nose of the bolt into a safety latching position (Fig. 3). Further closing causes the bolt 3 to move backwards - downwards pivoting being prevented by leg 10 engaging base 31 of the casing - with pivoting of lever 12 until the line joining the point of contact of striker pin 32 with bolt 3 to pivot 4 has moved overcentre, from one side of pivot 13 to the other (Fig. 1). This is the full latching position. During this latter action, the line of force of spring 14 on pivot 4 also moves from one side of pivot 13 to the other, thus utilising the force of this spring to pull the bolt 3 and pin 32 and, therefore, the car door, into the fully engaged position. Unlatching is produced by rotation of plate 17 to cause its arm 22 to depress bolt pivot 4 to reproduce the safety latching position with second arm 24 under surface 11 of the bolt 3. This provides a fulcrum for further rotation of plate 17 to cause the bolt to pivot out of engagement with striker pin 32. The latch may be locked by pivoting arm 27 into engagement with shoulder 25 on plate 17, thus preventing unlatching. <IMAGE>

Patent GB-2382228-A (GB)
Title: Dual beam monopulse antenna system
Inventor: NELSON EVERETT ARCHER
IPC: G01S13/44
Filed: 1981-06-11
Abstract: A dual beam monopulse antenna system includes a flat plate antenna (fig.1, not shown) divided into quadrants each comprising a plurality of slotted waveguides (20). Each of the quadrants is provided with primary and secondary feed lines which are connected through directional couplers (42-136) to connecting lines (146-192) to the slotted waveguides (20). The primary feed lines (26, 28, 30, 32) are connected to a primary monopulse comparator network and the secondary feed lines (34, 36, 38, 40) are connected to a secondary monopulse comparator network. The sum and difference of terminals of the monopulse comparator networks are connected to switch networks (322, 332, 342). The switch networks have a first state to generate a pencil beam in which the slotted waveguides (20) are connected to the system summation terminal (330), system azimuth terminal (340) and system elevation terminal (350) via the primary feed lines alone. In a second state the switch networks are set such that the slotted waveguides (20) are connected to both the primary and secondary feed assemblies and therefore to the primary and secondary monopulse comparator networks. In the second state the slotted waveguides (20) produce a shaped search beam which has a greater vertical dimension than horizontal dimension. The antenna system, however, operates in the monopulse mode with both antenna beams. The system can be rapidly switched from one beam shape to the other. Polarization discs are positioned parallel to and spaced apart from antenna (10) to select a polarization desired for the beam produced by the antenna system by rotation of the polarization disc.
