Abstract: 1,200,122. Fishing reels. PENN FISHING TACKLE MFG. CO. 24 Aug., 1967, No. 39069/67. Heading A1A. The rotatable spool 36 of a reel has a brake device comprising a plate 34 mounted on pins 35 to allow axial sliding movement of the plate relative to the spool, and two friction discs 33 one on each side of the plate associated with two driving plates 20, 20a which are splined on a central shaft 30 and are held apart by spring 37. The spool is moved axially to apply the friction discs to the plate 34 by means of a lever 76 rotation of which moves pins 62 along cam faces whereby the bearing 60 and thus the spool is axially moved. The brake is initially adjusted by rotation of knob 92 acting through a gear to screw the part 70 with respect to the part 68. A pawl and cam connection between the driving plate 20 and the end plate of the reel frame allows rotation of the spool in the winding-in direction when the brake is applied. Radially disposed resiliently outwardly urged stops (83) and (85) Fig. 1 (not shown) are provided in the path of movement of the stop finger 78 but they may be depressed to allow the finger to pass. When the finger 78 abuts the pin (83). The spool is in the free spool position and when the finger abuts the stop (85) full braking is applied. In an embodiment the spool is driven by an electric motor.

Title: Improvements in or relating to squirrel cage rotors
IPC: H02K17/18
Filed: 1958-12-04
Abstract: 904,171. Squirrel-cage constructions. WESTPHALEN, W. Dec. 4, 1958 [Dec. 5, 1957; Jan. 15, 1958; March 7, 1958; Sept. 23, 1958], No. 39109/58. Class 35. A squirrel-cage rotor for use in an induction motor has at least two intersecting groups of short-circuited conductors, the conductors of at least one group being arranged obliquely to the rotor axis. The rotor preferably consists of a number of identical laminations. In one embodiment a lamination comprises one group of eighteen equally spaced slots, and a second group of twenty equally spaced slots so arranged that at least one slot of one group coincides with a slot of the second group. The discs may be divided into nineteen equal divisions and are stacked so that each disc is displaced from the preceding one by one division. The conductors are then formed by pouring or spraying material into the channels thus formed. The angle of obliquity of the conductors may be varied by displacing each disc by <SP>1</SP>/xth of a division from the preceding one. The number of divisions selected preferably lies between the numbers of conductors in the two groups, or may be the sum of these numbers. The groups may be oblique to the axis in the same sense if a number of divisions greater or less than the numbers of conductors is selected (i.e. seventeen or twenty-one divisions instead of nineteen). The slots may have either of the forms shown in Figs. 1, 1b. In the latter case each group of conductors comprises pairs of interconnected conductors and the outer conductors of the pairs of the two groups may have different resistances whereby the starting properties of the two groups may differ. To facilitate assembly, packing tongues may be inserted in holes near the centre of each disc (Fig. 3, not shown), there being one hole in each division. The packing tongues may alternatively be arranged in slots in the periphery of each disc (Fig. 4, not shown) if the rotor is large, some of these slots then coinciding with the conductor slots. In this case the additional slots are also filled with conducting material after removal of the packing tongues, resulting in a conductor network as in Figs. 5 or 6 (not shown). A rotor according to the invention may be used in a brakemotor (Fig. 8) where 11 is the stator, 12 is the rotor, 14 is an armature actuated by a fluxswitching portion 18 of the rotor. Brake shoe 16 is moved out of contact with the brake surface 17 by armature 14 when the rotor is switched on.

Title: A single lens hinged-mirror-reflex camera
IPC: G03B9/07
Filed: 1968-10-14
Abstract: 1,246,671. Reflex cameras. FRANKE & HEIDECKE G.m.b.H. [trading as ROLLEI-WERKE FRANKE & HEIDECKE]. Oct. 14, 1968 [Oct. 14, 1967], No. 40203/68. Heading G2A. A single-lens reflex camera comprises a between-the-lens pivoted blade shutter and a focal plane roller blind shutter. The blade shutter is open when cocked and when uncocked. When the blade shutter is required it is cocked and upon camera release, the following sequence takes place: the mirror pivots up, the blade shutter closes, the diaphragm shuts down to a pre-set value, the focal plane shutter opens, the blade shutter opens and closes to effect an exposure, the focal plane shutter closes, the mirror pivots down, the blade shutter opens, and the diaphragm moves to its fully open position. As shown in Fig. 3 the blade shutter comprises blades 28A mounted between a first ring 28 and a second ring (not shown). The shutter has been tensioned by moving a lever 36 which moves a lug 39 attached to the second ring, movement of lever 36 also tensioning springs 32, 34 and engaging a pin 42 with a ledge 41 of a lever 33. Upon shutter release the mirror (not shown) pivots up and moves a step 1 Fig. 1 in direction B allowing a spring 10 to rotate an assembly 3, 5, 14, 19 anti-clockwise. This movement releases from member 19 a pawl 20 joined to a ring 26. Spring 34 rotates ring 26 clockwise through the connection 41, 42. Ring 26 is joined to shutter ring 28 at 29 and thus ring 28 rotates to close blades 28A. Movement of assembly 3, 5, 14, 19 also moves a diaphragm blade ring 11 to close blades 11B until pin 18 engages a pre-set cam 17. Movement of step 1 also initiates a mechanism (not shown) to open and close the focal plane shutter at the correct times. Spring 34 continues to move ring 26 until notch 24 in pawl 22 engages member 19 and as lever 26 moves a lug 31 thereon strikes a catch 30 which releases the second shutter ring (not shown) for rotation to open and close blades 28A to effect an exposure. During movement of this second ring, lug 38 thereon strikes lever 44 disengaging the connection 41, 42. Spring 32 now seeks to rotate ring 26 anti-clockwise. This is possible when the mirror pivots down again, as step 1 is moved in direction B and assembly 3, 5, 14, 19 is moved clockwise. This moves the diaphragm to its fully open position and releases pawl 22 from member 19 to allow rotation of rings 26 and 28 to close the blades 28A.

Title: Colour Television Signal Amplifier
IPC: H04N9/68
Filed: 1966-09-13
Abstract: 1,155,468. Colour television receiver. INTERNATIONAL STANDARD ELECTRIC CORP. 13 Sept., 1966 [15 Sept., 1965], No. 4O879/66. Heading H4F. In a colour television receiver for PAL type signals in which the colour burst alternates between 135 and 225 degrees with respect to B-Y from line to line, i.e. a " swinging burst ", the colour saturation control circuit is such that amplitude variation of the chrominance signal is rendered ineffective during the period of the burst pulses, and the colour subcarrier oscillator is synchronized by the phase-constant component of the burst signal. The colour saturation control circuit which is inserted in the chrominance signal path between the IF- demodulator and the time demodulator stage of the PAL-decoder comprises a switching diode 12, Fig. 2, earthed at its cathode and connected at its anode to a steady source of positive biasing potential U b  via a resistor 14 and to a source of negative line fly-back pulses via a resistor 13. Connected to the common junction point of these elements are potentiometers 9 and 10 and resistor 15 to which is fed via capacitor 8 the chrominance signal from, for example, a chrominance signal amplifier. The output to the PAL- decoder is taken via capacitor 11. Diode 12 is normally conductive but is blocked by the negative fly-back pulses which interrupts the connection of potentiometers 9 and 10 to ground and thus renders them ineffective for amplitude control of the chrominance signals during the burst pulses. Potentiometers 9 and 10 may alternatively be bridged by means of a switch which is closed by the line fly-back pulses. In a second embodiment, Fig. 3, the chrominance signal is fed to the base of transistor 17 via capacitor 16 and an inductively coupled band-pass filter 18-24, 30 is provided in its collector circuit. The chrominance signal is removed via capacitor 31. The base of transistor 17 receives in addition to the chrominance signal a manually variable voltage U v  applied via resistor 28 and coil 27, and also positive line fly-back pulses applied via a capacitor 29 and the coil 27. The resistor 28 is of a value such that the voltage U v  is practically ineffective during the presence of positive line fly-back pulses and thus the amplification of the burst signal is determined by the amplitude of the pulses. In the absence of such pulses, the amplification of the chrominance signal is determined by the magnitude of the variable voltage U v .
